DETAILED DESCRIPTION

[0032] The following will be combined with the Figure 1 -Appendix Figure 3 , the present application is further described in detail.

[0033] A bidirectional reciprocating universal hinge, referring to Figure 1The system includes a mounting base 1, on which two baffles 2 are mounted. A hinge wheel 3 is rotatably mounted on the baffles 2. A hinge wheel rail for winding a wire rope is provided on the circumferential side wall of the hinge wheel. Several first mounting plates 4 are provided on the other side of the mounting base 1. All the first mounting plates 4 are rotatably connected to second mounting plates 5. Since the first baffles 2 and the second baffles 2 are rotatably connected, they can withstand the lateral force of the bidirectional reciprocating universal joint, thus solving the problem that the bidirectional reciprocating universal joint is prone to detachment under lateral force.

[0034] refer to Figure 2 A one-way thrust ball bearing 6 is provided at the rotatable connection between the first mounting plate 4 and the second mounting plate 5. One side of the one-way thrust ball bearing 6 abuts against the first mounting plate 4, and the other side abuts against the second mounting plate 5. The one-way thrust ball bearing 6 transforms sliding friction into rolling friction. The one-way thrust ball bearing 6 significantly reduces the friction between the first mounting plate 4 and the second mounting plate 5, reduces wear caused by friction, and extends the service life of the bidirectional reciprocating universal joint. Moreover, the design of the one-way thrust ball bearing 6 can ensure the accuracy and stability of the bidirectional reciprocating universal joint during rotation.

[0035] refer to Figure 2 The outer wall of the fixed plate 7 is provided with a support rib 8. The rotational connection between the second mounting plate 5 and the fixed plate 7 realizes the universal rotation of the bidirectional reciprocating universal hinge. The outer wall of the fixed plate 7 is extended with a support rib 8, which effectively enhances the overall rigidity and load-bearing capacity of the bidirectional reciprocating universal hinge and reduces the possibility of deformation or breakage of the fixed plate 7 due to excessive load during use.

[0036] refer to Figure 2 The support rib 8 and the fixing plate 7 are connected by a connecting hole 9. The connecting hole 9 passes through the support rib 8 and the fixing plate 7, thus enhancing the rigidity and load-bearing capacity of the bidirectional reciprocating universal joint after it is fixed, and ensuring the integrity and safety of the bidirectional reciprocating universal joint.

[0037] refer to Figure 2 A pressure bar 10 is provided between the two baffles 2 and at the edge of the hinge wheel 3 rail. The baffle 2 is located above the hinge wheel 3 rail and the pressure bar 10 is provided to prevent the wire rope from detaching from the hinge wheel 3 rail due to excessive swing amplitude caused by gravity. This effectively realizes the stability and safety of the bidirectional reciprocating universal hinge.

[0038] refer to Figure 3 The two ends of the pressure rod 10 are rotatably connected to the corresponding baffles 2. When the bidirectional reciprocating universal joint is in use, the back-and-forth sliding of the wire rope will increase the collision between the wire rope and the pressure rod 10. The pressure rod 10 is equipped with a rotating device to reduce the impact of the pressure rod 10 on the sliding of the wire rope when the bidirectional reciprocating universal joint is in operation, effectively increasing the usability of the pressure rod 10.

[0039] refer toFigure 3 The outer side wall of the pressing rod 10 is provided with a plastic sealing layer 12, which wraps the outer side wall of the pressing rod 10. The collision between the pressing rod 10 and the steel wire rope will cause wear between them. The plastic sealing layer 12 can effectively protect the pressing rod 10 and reduce the wear between the pressing rod 10 and the steel wire rope, thereby prolonging the service life of the pressing rod 10. The material of the plastic sealing layer 12 is polyformaldehyde or nylon.

[0040] With reference to Figure 3 The plastic sealing layer 12 and the pressing rod 10 are provided with a plurality of screw holes for inserting the screws 13. The screw holes of the plastic sealing layer 12 and the pressing rod 10 are threadedly connected with the screws 13. The screws 13 are used to connect the pressing rod 10 and the plastic sealing layer 12. The screws 13 effectively increase the firmness of the plastic sealing layer 12 and reduce the possibility of direct falling due to aging and damage. When the plastic sealing layer needs to be replaced, the screws 13 are unscrewed and then knocked out until the pin is removed, and then the plastic sealing layer 12 is removed to achieve the replacement of the plastic sealing layer 12, thereby effectively increasing the convenience of the pressing rod 10.

[0041] With reference to Figure 3 The outer side wall of the plastic sealing layer 12 is provided with a groove 14 at the position of the hinge wheel track 15. The groove 14 increases the movement range of the steel wire rope between the pressing rod 10 and the hinge wheel track, thereby effectively reducing the collision and friction between the plastic sealing layer 12 and the steel wire rope.

[0042] The implementation principle of the embodiment of the present application is as follows:

[0043] When the bidirectional reciprocating universal hinge is subjected to a lateral force, the first mounting plate 4 and the second mounting plate 5 can disperse the lateral force and reduce the possibility of the bidirectional reciprocating universal hinge being detached, thereby effectively increasing the stability of the bidirectional reciprocating universal hinge. The one-way thrust ball bearing 6 is arranged between the first mounting plate 4 and the second mounting plate 5 to change the sliding friction between the first mounting plate 4 and the second mounting plate 5 into rolling friction, thereby effectively reducing the wear caused by friction and effectively prolonging the service life of the bidirectional reciprocating universal hinge. The second mounting plate 5 is rotationally connected with the fixed plate 7 to achieve the universal rotation of the bidirectional reciprocating universal hinge. The reinforcing ribs are arranged on the fixed plate 7 to effectively avoid the possibility of the deformation of the fixed plate 7 caused by the overloading of the connected articles.

[0044] The pressing rod 10 is arranged between the baffles 2 to effectively reduce the possibility of the steel wire being detached from the hinge wheel track due to the excessive amplitude in the swinging process. The pressing rod 10 is rotationally connected with the baffles 2 to effectively reduce the friction between the pressing rod 10 and the steel wire rope. The outer side wall of the pressing rod 10 is provided with the plastic sealing layer 12 to effectively protect the pressing rod 10 from being broken due to the collision of the steel wire rope. The plastic sealing layer 12 is provided with the screws 13 for the replacement of the plastic sealing layer 12. The plastic sealing layer 12 is provided with the groove 14 to reduce the friction between the steel wire rope and the plastic sealing layer 12.

Therefore, any equivalent changes made on the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
