Description

Quick buckle type chain disassembly tool structure

This creation is about a kind of chain disassembly tool, especially a kind of structure applied to quick-lock chain disassembly tool.

Press, there is a conventional quick-lock chain, such as the structure of Figure 1 and Figure 2 described in the national patent No. I370208. The chain includes an array of serial units and a chain that connects two serial units on opposite ends of the chain. In the series-connected joint group, the series connection unit includes two parallel-spaced inner chain pieces and two outer chain pieces respectively located outside the inner chain pieces. And the joint set includes: two pieces of joint pieces spaced inside and outside and two connecting shafts. Each tab has a circular fixing hole and a button hole spaced from the fixing hole. The button hole has a large hole and a small hole connected to the large hole. Each of the connecting shafts has a fixing part connected to the fixing hole of one of the connecting pieces, and a buckling part extending into the button hole of the other connecting piece through the series connection unit.

When assembling the joint assembly, the fixing parts of the two shafts must be combined with the fixing holes of each joint piece in advance, and then the buckling parts of the two joint shafts pass through the series connection unit at the same time and face the size of the other joint piece. The hole is extended, and finally the tabs are relatively displaced along the length direction, so that the buckling part of the shaft is caught in the small hole of the buckle hole, and the assembly is completed. To disassemble the connector set 2, follow the above assembly steps in reverse order.

However, when the above-mentioned chain structure is assembled, the buckling part of the shaft can be locked in the small hole of the buckle by applying force outwards. However, when the chain structure is to be disassembled, the chain must be disassembled. Apply force inward to squeeze the shaft to move toward the larger hole, so that the shaft can escape the blocking effect of the small hole and then the chain can be disassembled. However, the assembly and disassembly of the quick-lock chain are traditionally used. It is operated by applying force with both hands, and it is reliable and brute force to pull outwards when combined, but when disassembling, because the chain is assembled by several chain blocks, it is difficult to squeeze inward with force. It is technically inconvenient to disassemble the quick-lock chain, and it is necessary to improve it.

In view of this, the creator has been engaged in the manufacturing, development and design of related products for many years, and after detailed design and careful evaluation for the above goals, he finally got a practical creation.

The technical problem to be solved by this creation is to provide a quick-lock type chain disassembly tool structure in view of the above-mentioned shortcomings existing in the prior art.

The above structure includes a dismounting tool, the dismounting tool is provided with two clamping arms, the front ends of the two clamping arms are each provided with a clamping claw, and the end portions are both provided with a through hole in the transverse direction, and are pivotally connected by a mandrel, and the clamping arm A through hole is provided in the same direction as the perforation, and the other clamp arm is provided with a screw hole in the same direction as the perforation. A screw rod passes through the through hole of the clamp arm and is locked to the other clamp arm. The screw hole allows the two clamping arms to be restricted by the mandrel and the screw and can only move horizontally, and then the screw is actuated by the screw to allow the two clamping arms to lean against each other, and the clamping jaws are used for chain disassembling operations By.

Preferably, the outer diameter of one end of the mandrel is provided with an embossed section, and the embossed section is penetrated and fixed in a through hole of the clamp arm, and the other end of the mandrel is along the other through hole of the clamp arm. Telescopic displacement.

Preferably, an elastic piece is further provided between the two clamping arms, and the elastic piece is passed through the On the screw rod, one end of the screw rod is formed with a big head-shaped stop part and restricted outside one clamping arm, and the other end is additionally screwed with a head bolt and restricted outside the other clamping arm.

Preferably, a limit stop wall is formed between the front end of the clamping arm and the clamping jaw in an L shape.

Preferably, a concave arc is formed on the inner side of the clamping jaws of the two clamping arms, and a limiting recess is provided on the front end surface of each clamping arm along the concave arc.

Comparing the effects of the previous technology: the size of the disassembly tool in this creation is only between the length of two to three links of a chain. It is small in size and convenient for storage, which is conducive to consumers to carry out and use the hexagonal wrench when disassembling and using. , Cross screwdriver and other hand tools can screw the screw, and then link the two clamping arms to move against each other, and through the two clamping jaws to achieve the purpose of chain removal operation, so that consumers can be more labor-saving and convenient In this way, the chain is disassembled and decomposed, which greatly improves the practicality of the structure.
