Existing chains require manual installation, which is labor-intensive. Furthermore, effective chain positioning is often not performed during installation, which affects installation speed and accuracy, causing numerous inconveniences.

[0003] In response to the above problems, the patent document with authorization announcement number CN221097363U discloses a driving installation tool for installing a large chain. The installation tool is provided with a first fixed column and a second fixed column parallel to each other at both ends of the base, and a placement cavity is formed between the two fixed columns, and the lower portion of the second fixed column is horizontally slidably connected to the base, and two positioning frames are provided in the placement cavity, both of which are connected to the second fixed column, so as to respectively position the first installation chain and the second installation chain to be connected, and the positioning frame is provided with a driving device for driving the two positioning frames to move in opposite directions at the same time, and an auxiliary installation component is provided in the placement cavity at the lower parts of the two installation chains; when in use, after installing the auxiliary installation component, the second fixed column is pushed toward the first fixed column to move until the two installation chains slide into the interior of the positioning frame, and then the two installation chains are positioned respectively by using the positioning pin to cooperate with the positioning hole opened on the positioning frame, and then the connecting shaft is installed into the connecting hole of the two installation chains using the auxiliary installation component to realize the installation of the chain.

[0004] Although the above-mentioned installation tool can move the second fixed column to drive the two positioning frames to move in opposite directions, so that the two installation chains are close to each other until a predetermined distance is reached, and finally the connecting shaft is installed into the connecting holes of the two installation chains through the auxiliary installation component to complete the installation of the chain, its structure is complex and the operation process is cumbersome, which increases the complexity of the operation and the possibility of errors, resulting in low installation efficiency.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0025] It should be noted that the main idea of ​​the chain quick tool provided by the utility model is: by setting a rotating mechanism including a first threaded segment and a second threaded segment, the threads on the two threaded segments are rotated in opposite directions, and a chain fixing is screwed onto each of the two threaded segments. The opposite ends of the two threaded segments are respectively rotatably connected to the outer shell and connected to a straight rod segment that passes through the outer shell and extends outward. A chain fixing is screwed onto each of the two threaded segments, and a one-way locking mechanism is fixedly installed on the threaded segment connected to the straight rod segment. By rotating the straight rod segment to drive the two threaded segments to rotate, the two chain fixings drive the two chains to approach or move away from each other, so that they move a predetermined distance, thereby completing the disassembly and assembly of the chain.

[0026] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below. The numbers of any elements in the drawings are for illustration only and not for limitation, and any names are for distinction only and do not have any limiting meaning.

[0027] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0028] Example 1 of the chain quick connection tool provided by the present utility model:

[0029] like Figure 1 and Figure 2 As shown, the chain quick connection tool includes a housing 1, a rotating mechanism is installed in the housing 1, and two chain fixing parts and a one-way locking mechanism are installed on the rotating mechanism.

[0030] About the shell 1. The shell 1 is a hollow cylindrical structure, with a first end seal 2 and a second end seal 3 at its left and right ends respectively. A through hole is opened at the center of the first end seal 2, and a rotating seat 11 is installed at the center of the left side of the second end seal 3.

[0031] Regarding the rotating mechanism. The rotating mechanism is an integrally formed structure, which consists of a straight rod section 4, a first threaded section 5, and a second threaded section 6 from left to right. The straight rod section 4 passes through the mounting hole from left to right. The first threaded section 5 and the second threaded section 6 are of equal length and have opposite thread rotation directions. The right end of the second threaded section 6 is fixedly connected to the rotating seat 11.

[0032] Specifically, the thread on the first thread segment 5 is a clockwise thread, and the thread on the second thread segment 6 is a counterclockwise thread.

[0033] Regarding the chain fixings. There are two chain fixings, which are screwed onto the first threaded segment 5 and the second threaded segment 6 respectively. The chain fixings include a fixing seat 7 screwed onto the threaded segments and extending up and down to penetrate the housing 1. A hook 8 is installed on the top surface of the fixing seat 7. The hooks 8 on the two fixing seats 7 are arranged opposite each other.

[0034] Correspondingly, guide grooves are provided on the top and bottom surfaces of the housing 1 for the fixing seat 7 to move left and right.

[0035] Regarding the one-way locking mechanism, the one-way locking mechanism includes a gear 9 fixedly mounted on the left end of the first threaded section 5 and a positioning member for preventing the gear 9 from rotating. A mounting hole for mounting the positioning member is provided on the housing 1.

[0036] Specifically, the positioning member is an elastic cylindrical pin 10 .

[0037] In addition, the chain quick connection tool also includes a rotating handle. The left end of the straight rod section 4 is the clamping end. The rotating handle includes a gripping portion 12 and a working end 13. A positioning hole 14 matching the size of the clamping end is provided at the center of the working end 13, so that after the clamping end is placed in the positioning hole 14, the gripping portion 12 is rotated to drive the clamping end to rotate, thereby driving the rotating mechanism to rotate, and finally realizing the two chain fixings to approach or move away from each other.

[0038] Specifically, the cross section of the clamping end is rectangular, and the positioning hole 14 is also a rectangular hole.

[0039] The working principle of the chain quick connection tool provided by the utility model is:

[0040] When connecting two chain sections, hook the ends of the two chain sections on the two hooks 8 respectively, put the positioning hole 14 on the clamping end, rotate the rotary handle clockwise until the rotating mechanism is locked clockwise, then insert the elastic cylindrical pin 10 into the mounting hole and make its bottom end contact with the gear 9 to lock the rotation of the gear 9, thereby locking the rotation of the rotating mechanism, and remove the rotary handle from the clamping end, and then fix the chain. If the chain is too long or too short during the fixed connection process, remove the two chain links from the hooks 8, and then add or remove chain links to adjust the length of the chain;

[0041] After the chain is fixedly connected, remove the elastic cylindrical pin 10, put the positioning hole 14 on the clamping end, rotate the rotating handle counterclockwise until the rotating mechanism is locked counterclockwise. During the rotation, the chain links are separated from the hook 8. Finally, insert the elastic cylindrical pin 10 into the mounting hole and make its bottom end contact with the gear 9 to lock the rotation of the gear 9, thereby locking the rotation of the rotating mechanism.

[0042] Example 2 of the chain quick connection tool provided by the present utility model:

[0043] The main difference between it and Example 1 is:

[0044] In Example 1, the chain fixing member includes a fixing seat and a hook installed on the top surface of the fixing seat.

[0045] In this embodiment, the chain fixing member includes a fixing seat and a vertically extending hanging rod installed on the top surface of the fixing seat.

[0046] Example 3 of the chain quick connection tool provided by the present utility model:

[0047] The main difference between it and Example 1 is:

[0048] In Example 1, the outer shell is a hollow cylindrical structure.

[0049] In this embodiment, the housing is a hollow rectangular structure.
