Description

Technical Field

[0001] The utility model belongs to the technical field of installing lock buckles, and in particular relates to a connecting lock buckle for a table top in a vehicle. Background Art

[0002] To improve the riding experience and comfort, commercial vehicles are currently equipped with flip-up tables for rear passengers. These tables are mostly installed with connecting rods, and a lock is provided on the upper end, which is mostly a rotating lock tongue. However, ordinary lock tongues have a simple structure and are prone to causing abnormal noises when opening or closing. At the same time, the stability will also be affected by the vibration of the car body, which can easily cause loosening.

[0003] Therefore, a connecting lock for a vehicle interior table top with a simple structure and stable assembly is in urgent need of research. Summary of the Invention

[0004] In view of this, the technical problem to be solved by the present invention is to provide a connecting lock for a table top in a car, so as to avoid the troubles of the previous table top lock having a single structure, being easy to loosen and having poor stability.

[0005] In order to solve the above technical problems, the utility model discloses a connecting lock for a vehicle interior table top, comprising:

[0006] An upper support, which is fixed to the back of the car seat and has a first pivot seat on its lower side;

[0007] The lower support is fixed to the upper end of the table top and corresponds to the upper support. The lower support has a downward-sloping buckle block;

[0008] A rotating paddle, wherein the lower end of the rotating paddle is connected to the first pivot shaft seat through the first pivot shaft, and the upper end of the first pivot shaft has a second pivot shaft seat, and the second pivot shaft seat is higher than the first pivot shaft;

[0009] The connecting buckle has an upper end connected to the second pivot shaft seat through a second pivot shaft, and a lower end provided with an inwardly facing buckle portion, and the buckle portion is used for buckling the slope buckle block.

[0010] According to one embodiment of the present invention, the upper end of the upper support further has a protruding limiting protection block, and the limiting protection block is higher than the second pivot shaft seat.

[0011] According to one embodiment of the present invention, screw mounting holes are respectively provided around the upper support and the lower support.

[0012] According to an embodiment of the present invention, the upper end of the rotating paddle is arc-shaped.

[0013] Compared with the prior art, the present invention can achieve the following technical effects:

[0014] The chair back and the table top are connected by respectively setting an upper support and a lower support, and then the rotating paddle and the connecting buckle are matched. By rotating, the connecting buckle is buckled with the lower support to form a locked table top, which has good stability and is easy to assemble.

[0015] Of course, any product implementing the present utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will describe the implementation of the present invention in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Please refer to Figure 1 and Figure 2 , Figure 1 This is a three-dimensional diagram of a connecting lock for a vehicle interior tabletop according to an embodiment of the present utility model; Figure 2 This is an exploded view of a connecting lock for a vehicle interior tabletop according to an embodiment of the present utility model.

[0023] As shown in the figure, a connecting lock for a table top in a car includes: an upper support 10, the upper support 10 is fixed to the back of a car seat, and has a first pivot seat 11 on the lower side; a lower support 20, the lower support 20 is fixed to the upper end of the table top, and corresponding to the upper support 10, the lower support 20 has a downward-facing inclined snap block 21; a rotating paddle 30, the lower end of the rotating paddle 30 is axially connected to the first pivot seat 11 through a first pivot 31, the upper end of the first pivot 31 has a second pivot seat 32, and the second pivot seat 32 is higher than the first pivot 31; a connecting snap 40, the upper end of the connecting snap 40 is axially connected to the second pivot seat 32 through a second pivot 41, and the lower end has an inward-facing snap portion 42, and the snap portion 42 is used to snap the inclined snap block 21.

[0024] In one embodiment of the present invention, the upper support 10 and the lower support 20 correspond to each other, one mounted on the front seat back, and the other mounted on the upper end of the table top. The lower end of the table top can be connected to the front seat back via a hinge or connecting rod. The upper support 10 is pivotally connected to the rotating paddle 30 via a first pivoting shaft 11. The rotating paddle 30 is also pivotally connected to the connecting buckle 40, which is used to lock the lower support 20.

[0025] The detailed operation process is as follows: because the second pivot seat 32 of the rotating paddle 30 is higher than the first pivot shaft 31, when the first pivot shaft 31 is rotated, the second pivot shaft 32 drives the connecting buckle 40 to have a certain lifting travel. As a result, when the rotating paddle 30 is pressed against the upper support 10, the connecting buckle 40 will move upward through the buckle portion 42 to lock the inclined buckle block 21, forming a fixed position. At this time, it is at a limit dead point and locked up and down. To unlock the buckle, just move the paddle 30 backward. It is easy to use and the buckle is stable, and it will not loosen due to vehicle body vibration.

[0026] In a preferred embodiment, the upper end of the upper support 10 further has a raised limiting protection block 50 , which is higher than the second pivot shaft seat 32 and serves to protect the second pivot shaft seat 32 at the lower end, providing good guiding and protective performance.

[0027] The upper support 10 and the lower support 20 of the present invention are respectively provided with screw mounting holes around their peripheries, so that the assembly is simple.

[0028] The upper end of the rotating paddle 30 is arc-shaped, which fits the finger pressing and is comfortable to operate.

[0029] In summary, the utility model connects the chair back and the table top by respectively setting an upper support 10 and a lower support 20, and then cooperates with the rotating paddle 30 and the connecting buckle 40. Through rotation, the connecting buckle 40 buckles the lower support 20 to form a table top locking, which has good stability and easy assembly.

[0030] The above description shows and describes several preferred embodiments of the present invention. However, as previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge in the relevant field. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
