Description

Two-position concealed box with infinite adjustment

Technical Field

The invention belongs to the technical field of electrical and electrical appliance accessory devices, and in particular relates to a stepless adjustable two-position concealed box.

Background technique

The concealed boxes on the current market are mostly spliced concealed boxes or multi-position concealed boxes, among which the existing multi-position concealed boxes have a certain size. The main sizes of the 86-type switch and socket products on the market are 86*90 and 86*86, which can only be used for products of a certain fixed size; and since the size of this product is fixed, it can only be installed for a switch of a certain size during installation. Therefore, after the multi-position concealed box is launched on the market, it has the defect of poor versatility.

Summary of the invention

In order to overcome the deficiencies of the prior art, the present invention provides a highly versatile stepless adjustable two-position concealed box.

In order to achieve the above object, the present invention adopts the following technical scheme: a two-position concealed box with stepless adjustment, comprising

The first box body can be buried on the wall;

A second box body can be buried in the wall, and there is a distance L between the second box body and the first box body;

A connecting structure, used to connect the first box body and the second box body, and the first box body can move left and right along the connecting structure to adjust the size of the distance L;

A locking structure cooperates with the connecting structure to position the first box body.

The present invention connects the first and second box bodies through a connecting structure. When using a two-position concealed box, the spacing L can be adjusted according to the size of the socket switch to adapt to the relative socket or switch panel. Therefore, the connection method through the connecting structure improves the versatility of the two-position concealed box and can be applied to more sockets or switch panels; and the locking structure is used to position the first box body, which can effectively ensure that the first box body will not be displaced during use, thereby ensuring stability and convenience when installing the panel.

Preferably, the connecting structure is a connecting rail that is at least partially penetrated on the first box body; by setting the connecting structure as a connecting rail, the first box body can move smoothly left and right along the box body, and can be moved to any position of the connecting rail as needed, realizing stepless adjustment, thereby achieving the best adjustment effect.

Preferably, the first box body is provided with a positioning portion that cooperates with the connecting rail, and the locking structure is provided on the positioning portion; by providing the positioning portion, the locking structure can lock the first box body and the connecting rail, so that the first box body and the second box body can no longer move, which makes it more convenient to install the panel.

Preferably, an anti-slip piece that cooperates with the first box body to limit the position is provided on the end of the connecting rail; the anti-slip piece can prevent the first box body from detaching from the connecting rail, which improves the convenience of adjusting the first box body.

Preferably, it also includes a support rod for resisting the positioning part to limit the upward or downward movement of the positioning part; the positioning part can be limited to move upward or downward by resisting the positioning part with the support rod, so that the positioning part is in close contact with the connecting rail. When the locking structure is locked, it can ensure close contact with the connecting rail and have a good locking effect. In addition, the support rod has the advantages of simple structure, not easy to be damaged and easy to install.

Preferably, an anti-slip piece that cooperates with the first box body to limit the position is provided on the end of the connecting rail; the anti-slip piece can prevent the first box body from detaching from the connecting rail, which improves the convenience of adjusting the first box body.

Preferably, the fixing structure comprises a first fixing portion provided on the connecting rail and a second fixing portion plugged with the first fixing portion, and the second fixing portion is provided on the second box body; by plugging and matching the first fixing portion and the second fixing portion, when connecting the connecting rail and the second box body, one end of the connecting rail can be inserted into the second fixing portion, which is simple and easy to install.

Preferably, the first fixing part is an elastic clip arranged on the connecting rail, and the second fixing part is a groove for the elastic clip to be inserted into; the first fixing part is provided with a first locking protrusion, and the second fixing part is provided with a second locking protrusion which is limitedly matched with the first locking protrusion; the elastic clip is arranged and inserted into the groove, and its structure is simple and easy to disassemble and assemble; the first locking protrusion and the second locking protrusion cooperate with each other to realize a quick connection between the connecting rail and the second box body, and the stability after the connection is high.

Preferably, the connecting rail is provided with a recessed portion, and the positioning portion is provided with a convex portion passing through the recessed portion; by providing the recessed portion and the convex portion, when the first box body moves left and right along the connecting rail, the side wall of the convex portion and the inner wall of the recessed portion will limit each other, thereby ensuring the stability of the first box body when it moves left and right.

Preferably, the locking structure is a bolt threadedly connected to the positioning portion; by setting the locking structure as a bolt, the contact area between the connection structure and the side wall of the connecting rail is large, the locking effect is good, and the structure of this method is simple and not easy to damage, thereby improving the service life of the entire two-position concealed box.

In summary, the present invention connects the first and second box bodies through a connecting structure, and the spacing L can be adjusted according to the size of the socket switch to adapt to the panel of the relative socket or switch, thereby improving the versatility of the two-position concealed box.
