Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a handrail hinge link that is easy to maintain. Background Technology

[0002] The hinge link of a car handrail is an important component that connects the car handrail to the vehicle body. It has a set of mounting heads at both ends that can be hinged. The performance of the hinge link directly affects the smoothness of the handrail's opening and closing and its service life.

[0003] Traditional hinge links often adopt an integrated structure design, and the hinge joints at both ends cannot be independently disassembled and assembled. When either hinge end fails, the entire link must be scrapped and replaced, resulting in a waste of material resources.

[0004] Therefore, to address the above issues, a handrail hinge link that is easy to maintain can be designed. Through a split structure design, the hinge joint and the link body can be combined in a standardized modular way. Each functional unit can be assembled and replaced independently. When a hinge module is worn or malfunctions, only the corresponding module needs to be replaced to restore the system function, which significantly reduces maintenance costs and improves material utilization. Utility Model Content

[0005] To overcome the problem that traditional hinge links mostly adopt an integrated structure design, the hinge joints at both ends cannot be independently disassembled and assembled, and when either hinge end fails, the entire structure must be scrapped and replaced, resulting in a waste of material resources.

[0006] The technical solution of this utility model is as follows: a handrail hinge link that is easy to maintain, including a link body and two sets of mounting heads respectively disposed at both ends of the link body, and a locking block. A first slot is provided at both ends of the link body. A plug-in block is fixedly installed at one end of the mounting head. The plug-in block matches the first slot. A second slot is provided on the front side of the link body. The locking block is disposed inside the second slot. Multiple sets of plug rods are fixedly installed on the rear side of the locking block. Multiple sets of through holes corresponding to the plug rods are provided on the side wall of the plug-in block.

[0007] Preferably, by setting the first slot to cooperate with the plug-in block, two sets of mounting heads can be spliced ​​to both ends of the connecting rod body respectively. By inserting the locking block into the second slot, multiple sets of plug rods pass through the through holes on the surface of the plug-in block, thereby locking the spliced ​​mounting heads and completing the standardized modular combination of the mounting heads and the connecting rod body, which is convenient for maintenance and replacement.

[0008] Preferably, the connecting rod body has multiple sets of bolts internally threaded, with one end of each bolt extending into the locking block and threadedly connected to the locking block.

[0009] Preferably, the inner wall of the second slot is embedded with multiple sets of anti-slip pads, which are in contact with the surface of the locking block.

[0010] Preferably, the front side of the locking block has a recessed latch.

[0011] Preferably, both the connecting rod body and the mounting head are equipped with oil injection channels.

[0012] Preferably, a sealing plug is engaged at the opening of the oil injection channel on the surface of the connecting rod body.

[0013] Preferably, a sealing gasket is provided at the connection between the oil injection channel of the mounting head and the oil injection channel of the connecting rod body.

[0014] The beneficial effects of this utility model are:

[0015] By engaging the first slot with the connector block, two sets of mounting heads can be respectively spliced ​​to both ends of the connecting rod body. Inserting the locking block into the second slot allows multiple connector rods to pass through the through holes on the connector block surface, locking the spliced ​​mounting heads. Bolts then secure the locking block inside the second slot, ensuring the stability of the mounting head splicing. Multiple anti-slip pads on the inner wall of the second slot increase friction, allowing the locking block to be stably inserted, reducing bolt connection pressure. This completes the standardized modular assembly of the mounting head and the connecting rod body. When a mounting head is damaged, the corresponding bolt is removed, and the corresponding locking block can be easily pulled out of the second slot using the recessed handle, unlocking the damaged mounting head. Simply replace the damaged mounting head and lock it using the above steps for normal operation, significantly reducing maintenance costs and improving material utilization.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment: a handrail hinge link that is easy to maintain, including a link body 1 and two sets of mounting heads 2 respectively disposed at both ends of the link body 1, and a locking block 3. A first slot 101 is provided at both ends of the link body 1. A plug-in block 201 is fixedly installed at one end of each mounting head 2, and the plug-in block 201 matches the first slot 101. A second slot 102 is provided on the front side of the link body 1, and the locking block 3 is disposed inside the second slot 102. The rear side of the locking block 3... Multiple sets of insert rods 301 are fixedly installed. Multiple sets of through holes 202 corresponding to the insert rods 301 are opened on the side wall of the plug block 201. By setting the first slot 101 to cooperate with the plug block 201, two sets of mounting heads 2 can be spliced ​​to both ends of the connecting rod body 1 respectively. By inserting the locking block 3 into the second slot 102, the multiple sets of insert rods 301 pass through the through holes 202 on the surface of the plug block 201, thereby locking the spliced ​​mounting heads 2 and completing the standardized modular combination of the mounting heads 2 and the connecting rod body 1, which is convenient for maintenance and replacement.

[0024] Please see Figure 3 and Figure 5 In this embodiment, the connecting rod body 1 is internally threaded with multiple sets of bolts 5, one end of each bolt 5 extending into the locking block 3 and threadedly connected to the locking block 3; by setting the bolts 5, the locking block 3 can be fixed inside the second slot 102, thereby ensuring the stability of the splicing of the mounting head 2; multiple sets of anti-slip pads 103 are embedded in the inner wall of the second slot 102, and the anti-slip pads 103 are in contact with the surface of the locking block 3; by setting the anti-slip pads 103, the friction can be increased, so that the locking block 3 can be stably inserted into the second slot 102, reducing the connection pressure of the bolts 5; a recessed handle 302 is provided on the front side of the locking block 3; by setting the recessed handle 302, it is convenient to apply force to the locking block 3, so that when replacing the mounting head 2, the locking block 3 can be pulled out from the second slot 102 to unlock the mounting head 2.

[0025] Please see Figure 1 , Figure 4 and Figure 5In this embodiment, both the connecting rod body 1 and the mounting head 2 are provided with an oil injection channel 4. The oil injection channel 4 allows for convenient addition of lubricating oil to the mounting head 2. A sealing plug 401 is fitted into the opening of the oil injection channel 4 on the surface of the connecting rod body 1. The sealing plug 401 protects the oil injection channel 4 from dust and debris when no lubricating oil is added. A sealing gasket 203 is provided at the connection between the oil injection channel 4 of the mounting head 2 and the oil injection channel 4 of the connecting rod body 1. The sealing gasket 203 seals the connection between the oil injection channel 4 of the mounting head 2 and the oil injection channel 4 of the connecting rod body 1, effectively preventing leakage and allowing the added lubricating oil to smoothly enter the interior of the mounting head 2.

[0026] By using the first slot 101 and the plug block 201 to cooperate, two sets of mounting heads 2 can be spliced ​​to both ends of the connecting rod body 1 respectively. By inserting the locking block 3 into the second slot 102, multiple sets of plug rods 301 can pass through the through holes 202 on the surface of the plug block 201, thereby locking the spliced ​​mounting heads 2. The locking block 3 can be fixed inside the second slot 102 by the bolt 5, thereby ensuring the stability of the splicing of the mounting heads 2. In addition, multiple sets of anti-slip pads 103 provided on the inner wall of the second slot 102 can increase the friction, so that the locking block 3 can be stably inserted into the second slot 102, reducing the connection pressure of the bolt 5, thereby completing the standardized modular combination of the mounting head 2 and the connecting rod body 1.

[0027] During normal maintenance, removing the sealing plug 401 allows for convenient addition of lubricating oil to the interior of the mounting head 2 via the oil injection channel 4. The sealing gasket 203 seals the connection between the oil injection channel 4 of the mounting head 2 and the oil injection channel 4 of the connecting rod body 1, effectively preventing leakage and allowing the added lubricating oil to smoothly enter the interior of the mounting head 2.

[0028] When a mounting head 2 is damaged, first remove the corresponding bolt 5. Then, using the recessed handle 302, the corresponding locking block 3 can be easily pulled out from the second slot 102, thereby unlocking the damaged mounting head 2. Simply replace the damaged mounting head 2 and lock the newly replaced mounting head 2 through the above operation, and it can be put into normal use, significantly reducing maintenance costs and improving material utilization.

[0029] Through the above steps, by cooperating with the first slot 101 and the plug block 201, the two sets of mounting heads 2 can be spliced ​​to both ends of the connecting rod body 1 respectively. By inserting the locking block 3 into the second slot 102, multiple sets of plug rods 301 pass through the through holes 202 on the surface of the plug block 201, thereby locking the spliced ​​mounting heads 2. This completes the standardized modular combination of the mounting heads 2 and the connecting rod body 1. When a module is worn or malfunctions, only the corresponding module needs to be replaced to restore the system function, significantly reducing maintenance costs and improving material utilization. This solves the problem that traditional hinge connecting rods mostly adopt an integrated structure design, and the hinge joints at both ends cannot be independently disassembled and assembled. When any hinge end fails, the entire system must be scrapped and replaced, resulting in a waste of material resources.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
