Description

A new type of chain handle

technical field

The utility model relates to the field of power transmission and transformation maintenance tools, in particular to a novel chain handle.

Background technique

A wrench is a hand tool that uses the principle of leverage to turn bolts, screws, nuts, and other openings or sockets that are threaded to hold bolts or nuts. The wrench is usually formed with a jaw at one or both ends of the handle, and when an external force is applied to the handle, the opening or control sleeve of the bolt or nut can be twisted. When in use, an external force is applied along the thread rotation direction to turn the bolt or nut. Existing wrenches all operate by installing the sleeve on the handle through the fixed shaft on the handle, and there are also wrenches with multiple sleeves fixed on the handle in various ways. Although this wrench has many functions, In the actual material installation and maintenance, due to the huge difference in bolt types, during the maintenance process, the staff can carry up to 3-5 wrenches when working, and when using socket wrenches, it is also necessary to carry multiple sockets of different types. , When climbing the tower, carrying a variety of tools not only wastes the physical strength of the personnel, but also easily causes the tools to fall when changing jobs frequently. At the same time, the type of wrench or sleeve that is carried during maintenance is incorrect, and it is necessary to stop working to reselect the wrench. This not only increases the complexity of work and delays working hours, but also affects work efficiency.

Detailed ways

The accompanying drawings are for illustrative purposes only and cannot be construed as limiting the patent;

The present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.

Example 1

A new type of chain handle, please refer to Figure 1-2, including handle structure 1, chain 2, chain groove 3, adjustment gear 4, center bearing 5, stop tooth 6, spring 8, spring stop column 7, spring stop Column mounting groove 9, sliding block 10 and operating block 14; wherein the chain groove 3 is arranged on the side of the handle frame 1, one end of the chain 2 is placed in the chain groove 3, and the other end passes through the top of the handle frame 1 to connect with the sliding block 10 The sliding block is located inside the handle frame 1 close to the top position; the adjustment gear 4 is installed in the middle of the handle frame 1 through the center bearing 5, and the adjustment gear 4 adjusts the chain by rotating itself to engage the ratchet with the gap between the chain 2 The length of 2; the operation block 14 is connected with the top of the center bearing 5; the stop tooth 6 is installed below the adjustment gear 4; the top of the spring 8 is connected with the stop tooth 6, and the bottom end is connected with the spring stop post The top of 7 is connected; the bottom end of the spring stop post 7 is set in the spring stop post installation groove 9; the spring stop post installation groove 9 is located at the bottom of the handle structure.

In this embodiment, the top of the handle frame 1 is also provided with locking teeth 11 for matching bolts of different specifications.

In this embodiment, the handle frame 1 is further provided with a permanent magnet 12 , and the permanent magnet 12 is embedded in the handle frame 1 .

In this embodiment, the number of permanent magnets 12 is five, and the five permanent magnets are vertically arranged on the handle frame 1 .

In this embodiment, the handle frame 1 is further provided with a baffle 15 , and the baffle 15 is opposite to the adjustment gear 4 on a vertical plane.

In this embodiment, the baffle plate 15 is fixed on the handle frame 1 by fixing bolts 13 .

In this embodiment, the number of the fixing bolts 13 is 4, and the 4 fixing bolts are distributed in four corners.

The working principle of the utility model is as follows: when working, firstly, the bolt is stuck at the locking tooth 11, the stop tooth 6 is adjusted, and the chain 2 is tightened by rotating the adjustment gear 4 through the operation block 14, when the chain 2 matches the bolt , reversely adjust the stop tooth 6, at this time the position of the rotating gear 4 is fixed, and the position of the chain 2 cannot be changed, and then rotate the handle 1 in the direction of the elastic bolt to achieve the purpose of disassembling the bolt.

Since the chain 2 can be completely taken out from the chain groove 3, the wrench of the utility model can disassemble the middle bolt of the double-piece clamp that cannot be disassembled by the socket wrench, and can also adjust the length of the chain 2 to adapt to various bolt types, which is more convenient than ordinary wrenches. Practical and convenient. The adjustment gear 4 is a mechanical locking position, which is also more reliable. The utility model adds a permanent magnet 12, which can be temporarily adsorbed on the iron material, thereby fully increasing the working safety. Wherein the chain 2, the adjustment gear 4, and the stop gear 6 are designed to be detachable, and can be directly replaced to reduce the economic waste caused by direct scrapping when the parts are damaged.
