detailed description

The invention will now be further described with reference to the drawings and specific embodiments.

As shown in FIG. 1 to FIG. 12, a flip table includes a table frame, a telescopic tube 13, and a turning mechanism 17. The telescopic tube 13 carries the table frame via the turning mechanism 17. The length of the bellows 13 can be adjusted correspondingly to the table frame. High and low. The extension tube 13 includes an outer tube 131, an inner tube 132, an outer end plug 133 and an inner end plug 134. The outer end plug 133 is disposed at one end of the outer tube 131, and the inner end plug 134 is disposed at one end of the inner tube 132; the inner tube One end of the inner end plug 134 is inserted into one end of the outer tube 131 provided with the outer end plug 133; the outer end plug 133 has a roller body 1332, the roller body 1332 partially protrudes from the inner wall of the outer end plug 133; the inner end plug 134 The support portion 1341 and the engaging portion 1342 are located at the outer periphery of the inner tube 132, and the engaging portion 1342 is sleeved on the inner tube 132; the outer wall of the outer end plug 133 is fixedly connected to the outer tube 131, and the inner wall of the outer end plug 133 The inner tube 132 is gap-fitted; the support portion 1341 is fitted into the inner portion of the outer tube 131 and slides along the inner portion of the outer tube 131. The inner tube 132 and the outer tube 131 are in contact with each other via the inner end plug 134 and the outer end plug 133. The inner end plug 134 is in surface contact with the outer tube 131, and the outer end plug 133 and the inner tube 132 are in rolling friction. The resistance caused by the deviation of the size and shape of the outer tube 131 and the inner tube 132 is reduced, so that the lifting is smoother and smoother. It is less labor-saving when making height adjustments.

In order to reduce the friction between the inner end plug 134 and the outer tube 131, the inner end plug 134 of the present invention has a roller body 1343. The roller body 1343 is disposed on the support portion 1341, and the roller body 1343 partially protrudes from the surface of the support portion 1341. Thus, the inner end plug 134 and the outer tube 131 also have rolling friction.

The roller bodies 1332 and 1343 of the present invention can be used in two ways, a ball or a needle roller. For example, when the outer wall of the inner tube 132 is curved, a ball matching manner may be used; when the outer wall of the inner tube 132 is a flat surface, a matching manner of a needle roller may be selected; when the outer wall of the inner tube 132 is a flat surface, it may also be selected. The way in which multiple balls are arranged side by side.

The outer end plug 133 of the present invention has a ring body 1331. The ring body 1331 has a mounting hole. The roller body 1332 is disposed in the mounting hole. Since the roller body 1332 is in contact with the outer tube 131 and is in contact with the inner tube 132, the roller body 1332 can be placed in the mounting hole from the inside of the ring body 1331. At least one of the rollers 1332 can be used to help reduce the friction of the inner tube 132 relative to the outer end plug 133, or a plurality of evenly distributed. For example, the ring body 1331 is a square ring, and the ring body 1331 has four faces, and at least two needle rollers can be disposed on each face.

The ring body 1331 has a spring piece 1334; the outer tube 131 is provided with a lifting and locking mechanism 19, which can press the elastic piece 1334 such that the elastic piece 1334 is in close contact with the inner tube 132, and the outer tube 131 and the inner tube 132 are relatively stationary; or adjacent The elastic piece 1334 maintains a clearance fit relationship between the elastic piece 1334 and the inner tube 132, and the outer tube 131 and the inner tube 132 are relatively slidable. The lifting and locking mechanism 19 is a pressing rod; the outer tube 131 has an opening, and the opening is opposite to the elastic piece 1334; the pressing rod is disposed on the outer tube 131, and the rotating rod can rotate or close the elastic piece 1334.

The ring body 1331 has a recessed hole. Correspondingly, the outer tube 131 has a card 1311. When the ring body 1331 is coupled with the outer tube 131, the card 1311 is correspondingly received in the recessed hole, so that the outer end plug 133 is stably connected with the outer tube 131. .

The outer surface of the ring body 1331 of the present invention may further be provided with a ring step 1333. The outer tube 131 is butted together with the ring step 1333. The arrangement of the ring step 1333 facilitates the installation and positioning of the outer end plug 133 relative to the outer tube 131.

The support portion 1341 of the present invention cooperates with the inner wall of the outer tube 131, and has at least two mating faces disposed at intervals. The mating surface can be symmetrically arranged according to the shape of the inner wall of the outer tube 131, for example, a three-petal type and a four-petal type.

The bellows 13 of the present invention is used in conjunction with a gas pressure bar 15, which can adjust and fix the height of the bellows 13. The gas pressure bar 15 includes a pressure tube 151, a piston rod 152 and a valve needle 153. When the valve needle 153 is pressed, the piston rod 152 can be extended and contracted with respect to the pressure tube 151; the valve needle 153 is not pressed, that is, the valve needle 153 is in a normal state. The piston rod 152 cannot be expanded and contracted with respect to the pressure tube 151. The free end of the pressure tube 151 is fixedly connected to the lower end of the outer tube 131. The free end of the piston rod 152 is fixedly connected to the upper end of the inner tube 132. The fixed connection can be locked by using the nut 18, and the inner tube 132 and the outer tube 131 are The height change is synchronized with the change in the height of the gas pressure bar 15. When the gas pressure bar 15 is in the adjustable state, the inner tube 132 can be moved relative to the outer tube 131. When the height of the inner tube 132 is properly adjusted, the valve needle 153 is released, and the gas pressure rod 15 is The length is fixed. At this time, the heights of the corresponding inner tube 132 and outer tube 131 are fixed.

The inverting mechanism 17 of the present invention includes a positioning rod 171 and a tie rod 172; the positioning rod 171 and the rod rod 172 are respectively hingedly connected to the table frame; the table frame can be flat or erected relative to the positioning rod 171; the positioning rod 171 has a first positioning groove and a first When the table frame is flat, the pull rod 172 is connected to the first positioning groove; when the table frame is erected, the pull rod 172 is connected to the second positioning groove. When it is necessary to change the state of the table top 11, the connection position of the tie rod 172 can be changed.

In order to facilitate the user to perform the lifting operation, the flip table of the present invention includes a wrench 16, which presses the wrench 16 to change the state of the valve needle 153, thereby adjusting the length of the gas pressure bar 15. That is, the wrench 16 is hingedly coupled to the positioning rod 171; the wrench 16 is rotated to correspondingly disengage or squeeze the valve needle 153.

The flip table of the present invention also includes a table top 11 and a stand 14; the table top 11 is placed on the table frame; and the stand 14 is fixed to the lower portion of the bellows 13.

In the present invention, an outer end plug 133 and an inner end plug 134 are respectively disposed on the outer tube 131 and the inner tube 132, so that the frictional force when the outer tube 131 and the inner tube 132 move relative to each other is small, thereby facilitating the lifting operation and the operation force is small. By providing the lift lock mechanism 19, the safety of the flip table can be improved, and the table top 11 caused by the accidental collision can be prevented from falling. Also, since the turning mechanism 17 is provided, the flip table table 11 of the present invention can be erected, thereby reducing the floor space.

The above is a further detailed description of the present invention in connection with the specific preferred embodiments, and the specific embodiments of the present invention are not limited to the description. It will be apparent to those skilled in the art that the present invention may be made without departing from the spirit and scope of the invention.
