Description

Technical Field

[0001] This application relates to the field of hook technology, and more specifically to a hook with a replaceable connection structure. Background Technology

[0002] Maintenance workers typically carry a toolbox containing various tools when performing maintenance tasks. However, after conducting an on-site inspection, only one or two tools are often actually needed. Carrying the entire toolbox in this case would be inconvenient for the operation. Holding the necessary tools in hand has obvious drawbacks; if the work requires climbing or ascending, holding the tools would hinder movement.

[0003] The existing hooks have mostly fixed connection structures, which cannot be flexibly and quickly changed according to different work scenarios and tool types. This limits the adaptability of the hooks and further exacerbates the inconvenience of carrying and using tools. Utility Model Content

[0004] Therefore, this application provides a hook with a replaceable connection structure to solve the technical problems of inconvenience in carrying tools (carrying a toolbox increases the burden when there are few tools, and handheld tools hinder climbing), and the fixed connection structure of existing hooks, which lacks replaceability and is difficult to adapt to different tools.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A hook with a replaceable connection structure includes a hook body, a tool connector, and a waist hook. The front side of the hook body is provided with a slot. One end of the tool connector is slidably engaged in the slot, and the other end of the tool connector extends out of the slot to connect a tool. The waist hook is detachably disposed on the rear side of the hook body and is used to hang the hook body on the waist.

[0007] One end of the slot is provided with an inlet / outlet portion that allows the tool connector to enter and exit the slot, and the other end of the slot is provided with a diameter-reducing limiting portion that prevents the tool connector from sliding out of the slot; a locking member is provided on the side of the slot near the inlet / outlet portion, which is used to block the slot to restrict the entry and exit of the tool connector, and when the locking member is moved, the slot is unblocked.

[0008] Optionally, the slot is arranged vertically, the inlet / outlet portion is located above the diameter reduction limiting portion, the tool connector includes an abutment portion, a transition portion and a connecting portion arranged sequentially from top to bottom, the abutment portion is slidably engaged in the slot and abuts against the diameter reduction limiting portion, the transition portion passes downward through the diameter reduction limiting portion and extends out of the slot, and the connecting portion is used to connect the tool.

[0009] Alternatively, the connecting part includes a threaded connecting rod adapted to the tool, the threaded connecting rod being threadedly connected to the tool.

[0010] Alternatively, the connecting part may include a Velcro strap that is tied to the tool.

[0011] Optionally, the locking component includes an integrally formed locking part, a connecting shaft part, and a handle part. The side of the slot is provided with a mounting hole. The locking part passes through the mounting hole and is placed in the slot. The connecting shaft part is rotatably mounted in the mounting hole via a rotating shaft. The handle part is placed outside the mounting hole. A torsion spring is sleeved on the rotating shaft. When the handle is turned, the locking part is disengaged from the slot. When the handle is released, the locking part is located in the slot.

[0012] Alternatively, the waist hook is a "U"-shaped hook, the waist hook is arranged vertically, and the opening of the waist hook faces downward.

[0013] Alternatively, a clamping member is provided inside the opening of the waist hook, the lower end of the clamping member is fixed to the rear side of the opening, and the upper end of the clamping member extends obliquely upward to gradually tighten the opening.

[0014] Compared with the prior art, this application has at least the following beneficial effects:

[0015] This application discloses a hook with a replaceable connection structure. Firstly, the hook body, tool connector, and waist hook on the rear of the hook body allow tools to be hung on the waist at any time, freeing the hands of maintenance workers during tasks, especially facilitating operations such as climbing and ascending. Compared to carrying an entire toolbox, this reduces the worker's burden and improves operational convenience and flexibility. Secondly, one end of the slot has an inlet / outlet allowing the tool connector to enter and exit, while the other end has a reduced-diameter limiting part preventing the tool connector from sliding out. A locking element is located on the side of the slot near the inlet / outlet, blocking the slot and restricting the tool connector's movement. When the locking element is activated, the slot is released, allowing workers to flexibly and conveniently replace the tool connector according to different tool types and usage needs, improving the hook's adaptability to different tools. Because the tool connector is replaceable, workers can select the appropriate tool connector to connect to the corresponding tool according to different work scenarios, enhancing ease of use.

[0023] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] refer to Figures 1 to 4 As shown, this utility model provides a hook with a replaceable connection structure, including a hook body 1, a tool connector 2, and a waist hook 3. A slot 11 is provided on the front side of the hook body 1. One end of the tool connector 2 is slidably engaged in the slot 11, meaning one end of the tool connector 2 is engaged in and can slide within the slot 11. The other end of the tool connector 2 extends out of the slot 11 to connect a tool. The waist hook 3 is detachably mounted on the rear side of the hook body 1 and is used to hang the hook body 1 around the waist. Thus, through the hook body 1, the tool connector 2, and the waist hook 3 on the rear side of the hook body 1, tools can be hung around the waist at any time, freeing the hands of maintenance workers when performing tasks, especially facilitating operations such as climbing and ascending.

[0025] One end of the slot 11 is provided with an inlet and outlet portion that allows the tool connector 2 to enter and exit the slot 11, and the other end of the slot 11 is provided with a diameter reduction limiting portion that prevents the tool connector 2 from sliding out of the slot 11. That is, the tool connector 2 and the slot 11 are detachable through the inlet and outlet portion. One end of the tool connector 2 can enter and exit the slot 11 through the inlet and outlet portion, and the opening of the diameter reduction limiting portion is smaller than the opening of the inlet and outlet portion. The diameter reduction limiting portion restricts the tool connector 2 from sliding out of the slot 11.

[0026] A locking element 4 is provided on the side of the slot 11 near the inlet and outlet. The locking element 4 is used to block the slot 11 to restrict the entry and exit of the tool connector 2. When the locking element 4 is moved, the slot 11 is unblocked. That is to say, when one end of the tool connector 2 is in the slot 11, the tool connector 2 cannot be separated from the hook body 1 due to the restriction of the locking element 4 and the diameter reduction limiting part.

[0027] The locking element 4 and the diameter reduction limiting part restrict the tool connector 2 from disengaging from the hook body 1. By moving the locking element 4 to release the blockage in the slot 11, one end of the tool connector 2 slides out of the inlet / outlet and disengages from the hook body 1. This allows workers to flexibly and conveniently replace the tool connector 2 according to different tool types and usage needs, improving the hook's adaptability to different tools. Because the tool connector 2 can be quickly replaced, workers can select the appropriate tool connector 2 to connect the corresponding tool according to different work scenarios, improving ease of use.

[0028] In one specific embodiment, the slot 11 is arranged vertically, and the inlet / outlet portion is located above the diameter reduction limiting portion. The tool connector 2 includes an abutment portion 21, a transition portion 22, and a connecting portion 23 arranged sequentially from top to bottom. The abutment portion 21 is slidably engaged within the slot 11 and abuts against the diameter reduction limiting portion. The transition portion 22 passes downward through the diameter reduction limiting portion and extends out of the slot 11. The connecting portion 23 is used to connect the tool. Preferably, the abutment portion 21 is ball-shaped, engaged within the slot 11, and can slide up and down within the slot 11.

[0029] The connecting part 23 may be provided with a threaded connecting rod 231 adapted to the tool. The threaded connecting rod 231 is connected to the tool by threads. For example, it can be connected to any tool such as a lithium drill or a lithium wrench. Since the bottom of the tool is provided with a threaded hole, the threaded connecting rod 231 is connected to the threaded hole.

[0030] Alternatively, a Velcro strap 232 may be provided on the connecting part 23. The connecting part 23 is an arc-shaped sheet structure with symmetrical through holes. The Velcro strap 232 passes through the through holes and connects to the arc-shaped sheet structure. The Velcro strap 232 is then tied to the tool. For example, when connecting any tool such as a hammer, screwdriver, or wrench, simply use the Velcro strap 232 to tie the tool handle tightly.

[0031] The connection part 23 described above is easy to connect and disconnect from the tool, making it convenient to place and retrieve the tool.

[0032] In one specific embodiment, the locking member 4 includes an integrally formed locking part 41, a connecting shaft part 42, and a handle part 43. A mounting hole 5 is provided on the side of the slot 11. The locking part 41 passes through the mounting hole 5 and is placed within the slot 11. The mounting hole 5 has sufficient clearance to facilitate the rotation of the locking part 41. The connecting shaft part 42 is connected to the mounting hole 5 via a rotating shaft 7. The handle part 43 is located outside the mounting hole 5. A torsion spring 6 is sleeved on the rotating shaft 7. A counter-torsion spring is provided on one side of the connecting shaft part 42. The limiting groove 8 has a 6-position limit. One end of the torsion spring 6 is engaged in the limiting groove 8. The lower torsion arm of the torsion spring 6 abuts against the side wall of the limiting groove 8, and the upper torsion arm of the torsion spring 6 abuts against the upper side wall of the mounting hole 5. The bottom side of the handle part 43 abuts against the lower side arm of the mounting hole 5. When the handle part 43 is pulled upward, the locking part 41 disengages from the slot 11. At this time, the tool connector 2 can be removed or installed through the inlet and outlet parts. When the handle is released, the locking part 41 returns to the slot 11. By setting the locking part 4, not only is the tool connector 2 restricted within the slot 11, preventing the tool connector 2 from sliding out of the slot 11 from the inlet and outlet parts, but the slot 11 is also unblocked by pulling the locking part 4, facilitating the quick replacement of the tool connector 2.

[0033] In one specific embodiment, the waist hook 3 is a "U" shaped hook, the waist hook 3 is set in a vertical direction, and the opening of the waist hook 3 is set downward. The waist hook 3 is more suitable for hanging on the waist belt. When the waist hook 3 is hung vertically on the waist belt, since the direction of the waist hook 3 is consistent with the direction of the slot 11, the tool connector 2 is engaged with the diameter reduction limiting part in the direction of gravity, making the tool connection more stable.

[0034] The waist hook 3 has a clamping member 31 inside its opening. The lower end of the clamping member 31 is fixed to the rear side of the opening, and the upper end of the clamping member 31 extends obliquely upward to gradually tighten the opening. In this way, the clamping member 31 makes the waist hook 3 hang more securely on the belt.

[0035] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
