[0041] Embodiment 1:

[0042] The overturning backrest connecting corner code 40 of the present embodiment is applied to a backrest overturning device, as shown in Figure 1 and Figure 2 The backrest overturning device includes a support 10, a driving assembly 30 and two sets of connecting rod assemblies 20, and the driving assembly 30 and the two sets of connecting rod assemblies 20 are both installed on the support 10.

[0043] The driving assembly 30 comprises a driving rod 32 and a driving element 31 for driving the driving rod 32. The driving element 31 is fixedly installed on the support 10 and can be an electric motor, a pneumatic cylinder or a hydraulic cylinder. In the embodiment, the electric motor is taken as an example. The two ends of the driving rod 32 are connected with the two sets of connecting rod assemblies 20 respectively, and the screw block 33 is connected with the electric motor and the driving element support 10.

[0044] The connecting rod assembly 20 is movably installed on the support 10 and is driven to move by the driving rod 32. The ends of the two connecting rod assemblies 20 away from the support 10 are both provided with the overturning backrest connecting corner code 40 of the embodiment.

[0045] As shown in Figure 3 , the overturning backrest connecting corner code 40 comprises a corner code substrate 100, a hook corner code 200 and a lock catch 300. The corner code substrate 100 is connected with the connecting rod assembly 20 through bolts. The lock catch 300 is movably installed on the corner code substrate 100, and an elastic reset member 500 is arranged between the lock catch 300 and the corner code substrate 100.

[0046] Referring to the accompanying Figure 4 and the accompanying Figure 5 , the lock catch 300 is provided as one and is installed on the corner code substrate 100 through the stepped bolt 400. The lock catch 300 is rotatably connected with the corner code substrate 100. The convex ring 120 is arranged at the position where the corner code substrate 100 is connected with the stepped bolt 400. The lock catch 300 and the corner code substrate 100 form an installation gap through the convex ring 120.

[0047] The corner code substrate 100 is provided with a guide groove 130, which is in a circular arc shape. The lock catch 300 is integrally provided with a limiting block 310. The limiting block 310 is protrusively arranged towards the corner code substrate 100 and is inserted into the guide groove 130. The limiting block 310 and the guide groove 130 form a limiting structure.

[0048] The corner code substrate 100 is protrusively provided with a connecting lug 140. The lock catch 300 is provided with an avoiding hole 320 matched with the connecting lug 140. The avoiding hole 320 is in an arc shape. The connecting lug 140 is inserted into the avoiding hole 320.

[0049] The elastic reset member 500 is arranged between the lock catch 300 and the corner code substrate 100. The elastic reset member 500 is a torsion spring. The two ends of the torsion spring are respectively sleeved on the connecting lug 140 and the limiting block 310.

[0050] As shown in Figure 4 , the corner code substrate 100 is provided with a plurality of L-shaped hook grooves 110. One end of the hook groove 110 penetrates the corner code substrate 100 to form a mounting port. The mounting port is gradually increased to form an expanded port. In the embodiment, two hook grooves 110 are provided, and one of them is located at the edge of the corner code substrate 100.

[0051] Referring to the drawings Figure 6 and Figure 7 The end of the lock catch 300 is bent to form a lock cylinder 330. When the lock catch 300 is not under stress, the lock cylinder 330 overlaps the hook slot 110 to form a clamping structure.

[0052] The hook angle bracket 200 includes a clamping portion 220 and a connecting portion 210. The clamping portion 220 and the connecting portion 210 are integrally bent to form a 90° angle. The connecting portion 210 is provided with a plurality of mounting holes for connecting to a back cushion.

[0053] The clamping portion 220 is provided with a hook rod 230. The hook rod 230 is provided with at least two, and in this embodiment, two are provided. The outer side wall of the hook rod 230 is provided with a limiting protrusion 240. The hook rod 230 can be directly provided with a bolt, and the nut of the bolt can be used as the limiting protrusion 240.

[0054] The hook rod 230 cooperates with the hook slot 110. As shown in Figure 8 , during installation of the hook rod 230 into the hook slot 110, the limiting protrusion 240 can push the lock catch 300 to rotate and avoid interference. As shown in Figure 6 , after installation of the hook rod 230 is completed, the lock catch 300 is reset to form clamping. The lock catch 300, the elastic reset member 500, the hook rod 230, and the hook slot 110 form a clamping connection structure.

[0055] Working principle:

[0056] During installation, the two hook rods 230 are simultaneously pushed into the hook slot 110 along the mounting opening. During this process, the limiting protrusion 240 pushes the lock catch 300 to rotate. After the hook rod 230 is pushed to the bottom, it is moved to the end of the hook slot 110 in the vertical direction. The lock catch 300 is reset, and installation is completed.

[0057] During disassembly, the steps opposite to the installation steps can be completed.

[0058] Embodiment 2: As shown in Figure 9 and Figure 10 , the difference from Embodiment 1 is that only one lock catch 300 can be provided, and only two hook rods 230 can be provided. The lock catch 300 cooperates with the left hook slot 110 in Figure 10 to form a clamping connection structure.

[0059] The hanging rod 230 matched with the lock catch 300 is a movable hanging rod 231, and the hooking angle bracket 200 is provided with a movable slot 250, and the movable hanging rod 231 is slidably installed on the movable slot 250. A spring 600 is arranged between the hooking angle bracket 200 and the movable hanging rod 231, and the spring 600 is used to provide an elastic force to the movable hanging rod 231 away from the hanging rod 230. Under the action of the spring 600, the hooking angle bracket 200 is located at one end of the movable slot 250 away from the hanging rod 230, and the spring 600 can be a spring or a torsion spring. In the embodiment, the torsion spring is taken as an example.

[0060] The elastic force of the spring 600 is smaller than that of the elastic reset member 500. When the hooking angle bracket 200 is installed on the angle bracket substrate 100, the lock catch 300 overcomes the elastic force of the spring 600 and pushes the movable hanging rod 231 to the end close to the hanging rod 230.

[0061] Working principle:

[0062] During installation, the hanging rod 230 is first installed into the hook slot 110, and then the hooking angle bracket 200 is rotated around the hanging rod 230 to rotate the movable hanging rod 231 into the other hook slot 110. After the movable hanging rod 231 is rotated into the installation opening, the movable hanging rod 231 pushes the lock catch 300 to avoid, and when the hooking angle bracket 200 is rotated to the limit, the lock core 330 of the lock catch 300 is reset and pushes the movable hanging rod 231 to move to the end of the movable slot 250 close to the hanging rod 230 to complete the reset.

[0063] Embodiment 3: as shown in Figure 11 The difference from the embodiment 1 is that the movable hanging rod 231 is located between the two ends of the sliding slot of the hooking angle bracket 200 without external force.

[0064] During installation, the hooking angle bracket 200 is rotated around the hanging rod 230 to apply force, so that the movable hanging rod 231 is in contact with the angle bracket substrate 100. At this time, the hooking angle bracket 200 is continuously rotated to make the movable hanging rod 231 move away from the hanging rod 230, and after the installation of the hooking angle bracket 200 is completed, the hooking angle bracket 200 is clamped into the hook under the reset force of the spring 600. Therefore, the lock catch 300 can better complete the reset, and the situation that the lock catch 300 pushes the movable hanging rod 231 out of the hook slot 110 does not occur.

[0065] The embodiments of the specific embodiments are the preferred embodiments of the application, and are not limited to the protection scope of the application. Therefore, any equivalent changes made according to the structure, shape and principle of the application should be covered within the protection scope of the application.
