Description

Game car height adjustment mechanism

technical field

The utility model relates to a height adjustment mechanism capable of adjusting the height of a game car.

Background technique

Baby play vehicles, such as general ride-on walkers and strollers, are a kind of utensils for infants and young children to learn to walk. Its structure generally includes an upper plate, a support frame and a lower plate. The child sits on it, and the lower plate is equipped with a wheel set. The support frame is connected between the upper plate and the lower plate to support the upper plate, so that the baby can walk on the surface of the lower plate with the support of the upper plate. In order to facilitate the use of infants and children of different ages and heights, height adjustment mechanisms are usually added to the game car. As far as its use is concerned, there are usually two types of cross-tube type and upright type. The inclination angle of the tube, while the vertical support frame uses the inner and outer tubes to expand and contract to achieve the purpose of height adjustment. U.S. Patent No. 5,728,030 discloses a vertical height adjustment mechanism, which uses a button to match the positioning hole to achieve the purpose of height adjustment for the expansion and positioning of the inner and outer sets. When making the button enter the positioning hole, it is easy to be cut by sharp edges such as plastic burrs on the periphery of the positioning hole, which is not safe enough. Therefore, Chinese patent ZL200920001263.9 discloses an improved scheme, the structure of which is an inner support frame provided with a plurality of positioning grooves, and an outer support frame telescopically socketed with the inner support frame, and its height adjustment mechanism includes A knob, a clutch, and a fixed block. A protrusion is extended on the knob and the purpose of height adjustment is achieved by engaging the protrusion with the limiting groove. The advantage is that the height of the protrusion in the clutch can be adjusted as required so that Adjust the height of the game car, but its disadvantage is that the card is not firm, and the position is not easy to grasp, which makes the machine prone to failure during use.

Detailed ways

The game car 10 shown in Figure 1 includes a top plate 2, a base 3 and support frame groups 4 installed on both sides of the game car 10, and the top plate 2 is provided with a riding portion 21 and a storage tray 22 for riding. And put game groups, food or other objects.

As shown in Figure 2, the height adjustment mechanism 6 includes a support frame group 4, a height positioning seat 61, a positioning rod 65 and a button knob 66; the support frame group 4 includes an upper support frame 41 and a lower support frame 42, the two are slidably socketed to form a structure that can be stretched and adjusted in length, the upper support frame 41 is locked on both sides of the upper plate 2, and the upper and lower support frames 41, 42 can be telescopically adjusted in length so that the upper plate 2 can Adjust the distance and height from the ground relative to the base 3.

The base 3 is installed below the upper plate 2, and extends upward from both sides of the base 3 or inserts and fixes the lower support frame 42 and sockets a shell 43. The base 3 of this embodiment is provided with a jack 33 for inserting Connected to the lower end of the lower support frame 42. The base 3 can be equipped with some wheels 31, so that the game car 10 can move smoothly, and the base 3 can also be equipped with a game board 32 as shown in Figure 1, allowing the baby to step on the game and send out sound and light or music, creating entertainment effects.

A second elastic element 5 is provided between the upper support frame 41 and the base 3, so that shock absorption and elastic expansion and contraction effects are generated between the upper support frame 41 and the lower support frame 42, so that babies and children can enjoy the up and down movement when sitting on the seat part 21. The fun of bouncing.

The height positioning seat 61 is fixedly connected to the inside of the upper support frame 41, and is provided with a plurality of positioning grooves 62 arranged vertically, and a stop projection 63 is formed between the single positioning grooves 62. The positioning grooves described in this embodiment 62 are oppositely arranged, and a single positioning groove 62 is connected by a central guide groove 64 .

The button knob 66 is located between the upper and lower support frames 41, 42, and is installed on the surface of the support frame group 4 to drive the positioning rod 65 axially. The position projection 7 is buckled with the positioning groove 62 to be positioned at the first position 71, which can prevent the telescopic sliding of the upper and lower support frames 41, 42, so that the distance between the upper plate 2 and the base 3 is fixed; When the button knob 66 is driven, it can move through the central guide groove 64 and make the limit protrusion 7 break away from the positioning groove 62, so that the upper support frame 41 and the lower support frame 42 can be freely telescopically moved to other positions, thereby adjusting the upper plate 2 and the base 3 or the height from the ground, specifically, the limiting protrusion 7 can move axially, that is, along a direction perpendicular to the height positioning seat 61 to the second position 72 and disengage from the positioning groove 62.

As shown in FIG. 4 , the button knob 66 can drive the positioning rod 65 , so that the limiting protrusion 7 turns to a third position 73 against the wall of the stopping protrusion 63 to prevent it from automatically snapping into the positioning groove 62 . Furthermore, between the button knob 66 and the upper support frame 41 or the lower support frame 42, a first elastic element 67, such as a compression spring, can be provided to keep the limit projection 7 at the first position 71 or the third position 73.

As shown in Fig. 2, Fig. 3, Fig. 5 to Fig. 7, the limit protrusion 7 under the normal state can be kept at the first position 71 by the elastic element 67, preventing the telescopic sliding between the upper and lower support rods 41, 42 , thereby adjusting the distance between the upper plate 2 and the base 3 and the height above the ground. The operator can pull or push the button knob 66 (depending on the position of the second elastic element 67) so that the positioning rod 65 and the limit protrusion 7 can move axially, that is, perpendicular to the direction of the height positioning seat 61, to the second position 72 for a certain distance. Break away from the positioning slot 62 to allow the upper and lower support frames 41, 42 to slide telescopically. At this time, the operator can adjust the height of the upper plate 2 from the ground. Enter the positioning groove 62 to fix the height of the upper plate 2 from the ground.

As shown in FIG. 7 , when the limit projection 7 moves to the second position 72, if the key knob 66 is twisted, the driving positioning rod 65 is rotated by a certain angle and the limit projection 7 is moved to the third position 73, The elastic element 67 pushes the positioning rod 65, but because the limit projection 7 cannot pass through the central guide groove 64, the limit projection 7 is blocked by the stop projection 63 and remains in the third position 73, and cannot return to the card. The first position 71 of the person positioning slot 62 . When the limit projection 7 is held at the third position 73 and cannot be snapped into the positioning groove 62, the upper support frame 41 and the lower support frame 42 can resume free telescopic sliding, and further, the upper support frame 41 and the support frame group 4 or A second elastic element 5 is arranged between the bases 3 to form a shock absorber and have an elastic expansion and contraction effect. When the baby sits on the seating part 21, the baby will have the fun of bouncing up and down.

As shown in Fig. 2, Fig. 3 and Fig. 8, when the operator turns the button knob 66 to make the positioning rod 65 return to the position where the position-limiting protrusion 7 is parallel to the positioning groove 62, the elastic element 67 makes the position-limiting protrusion 7 snap into position. The groove 62 returns to the first position 71, so that the upper plate 2 stops the bouncing effect and is fixed at an adjusted height from the ground.

The height adjustment mechanism of the game car of the utility model can provide the operator to adjust the height of the game car by using the button knob, so as to be suitable for infants and young children of different heights.
