Description

Technical Field

[0001] This utility model relates to the field of power tools, and more particularly to an adjustable power equipment installation tool. Background Technology

[0002] Electrical equipment mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment mainly includes power plant boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment mainly includes transmission lines of various voltage levels, instrument transformers, contactors, etc. Wrenches are needed for the installation and maintenance of electrical equipment.

[0003] In related technologies, wrenches are generally hand tools that utilize the lever principle to tighten or loosen bolts and nuts. The force applied through the handle creates torque on a long lever arm, thereby amplifying the force and making operation more effortless. Different types of wrenches use specifically shaped heads to engage with fasteners, ensuring stable force application and preventing slippage. Through leverage and mechanical engagement, manual force is converted into greater rotational force to complete tightening or disassembly tasks.

[0004] Regarding the aforementioned technologies, the inventors believe that in practical applications, the operating space for bolts or nuts is often limited, and the construction environment is narrow. Generally, the wrench head and handle of a wrench used for tightening are fixed together and are usually formed as a long strip by integral casting. If there is an obstacle at the location of the handle when the wrench head is engaged with the bolt or nut, then the wrench head cannot engage with the bolt or nut in actual conditions, and the wrench will have difficulty completing the work of tightening or loosening the bolt or nut. Utility Model Content

[0005] To address the problem that existing power equipment installation tools are difficult to operate in confined construction environments, this invention provides an adjustable power equipment installation tool that can perform operations even in situations with limited space.

[0006] The adjustable power equipment installation tool provided by this utility model adopts the following technical solution:

[0007] An adjustable electrical device includes a wrench head that mates with a bolt and nut, a handle for gripping, a connecting handle for connecting the wrench head and the handle, and a rotating shaft. One end of the connecting handle is connected to the handle, and a first lug and a second lug are fixedly connected to the end of the connecting handle away from the handle. The first lug and the second lug are arranged opposite to each other. One end of the wrench head is fixedly connected to a third lug. The first lug has a first through hole, the second lug has a second through hole, and the third lug has a third through hole. The rotating shaft passes through the first through hole, the second through hole, and the third through hole in sequence. One end of the rotating shaft is provided with a fixing component for fixing the relative angle between the wrench head and the connecting handle.

[0008] By adopting the above technical solution, the wrench head and the connecting handle are connected by passing through the first lug, the second lug, and the third lug with a rotating shaft, and a fixing component is installed to fix the relative angle between the wrench head and the connecting handle. This allows the wrench head and the connecting handle to rotate relative to each other and adjust their angle, and the fixing component keeps their angle constant, so as to adapt to the operating space in different working environments and improve the portability and efficiency of the wrench.

[0009] Optionally, the fixing component includes a first gear and a second gear. The first lug is provided with a first locking groove that fits with the gear on the side away from the second lug. The first gear is embedded in the first locking groove. The first lug is provided with an embedding groove for the gear to be placed and rotated on the side near the second lug. The third lug is provided with a second locking groove that fits with the gear on the side near the first lug. The second gear is embedded in the second locking groove.

[0010] By adopting the above technical solution, after the wrench head is rotated to adjust the required angle between it and the connecting handle, the wrench head and the connecting handle are fixed by embedding the first gear in the first locking groove and the second gear in the second locking groove, so that the angle between the wrench head and the connecting handle no longer changes, simplifying the angle adjustment process between the wrench head and the connecting handle and improving the portability and stability of the wrench.

[0011] Optionally, a pressing piece is fixedly connected to the end of the rotating shaft away from the first gear, and a first compression spring is sleeved on the rotating shaft. One end of the first compression spring abuts against the side of the pressing piece near the second lug, and the other end of the first compression spring abuts against the side of the second lug away from the first lug.

[0012] By adopting the above technical solution, and by installing a pressing plate and a first compression spring, when the operator wants to adjust the angle between the wrench head and the connecting handle, the pressing plate can be pressed down to move the first gear out of the first locking groove and the second gear out of the second locking groove, so as to adjust the angle between the wrench head and the connecting handle. After adjustment, simply release the pressing plate, and the first gear will be brought back into the first locking groove and the second gear will be brought back into the second locking groove under the action of the compression spring to fix the angle, making the adjustment of the wrench angle more convenient.

[0013] Optionally, a rotating post is fixedly connected to the end of the connecting handle away from the wrench head, and a rotating hole is provided in the handle, with the rotating post passing through the rotating hole.

[0014] By adopting the above technical solution, and by providing a rotating column and a rotating hole, the handle and the connecting rod are connected together through the rotating column. This allows the force of the handle to be transmitted to the connecting handle through the rotating column, and the connecting handle drives the rotation of the wrench head, thereby increasing the lever arm of the wrench and reducing the difficulty of using the wrench.

[0015] Optionally, the handle is provided with a conversion assembly, the conversion assembly includes a plug rod, the side wall of the rotating hole is provided with a moving hole, the plug rod is slidably connected in the moving hole, the rotating column is provided with an anti-rotation groove, one end of the plug rod extending out of the moving hole is embedded in the anti-rotation groove, and the handle is provided with a first clearance groove for the plug rod to slide completely into the moving hole.

[0016] By adopting the above technical solution, and by providing a conversion component on the handle, when the insertion rod is inserted into the anti-rotation groove, the handle is embeddedly connected to the rotating column, and the handle can rotate around the rotating column as an axis to apply force. When the insertion rod is completely slid into the moving hole through the first clearance groove, the handle is disconnected from the embedded connection with the rotating column, so that the handle can drive the connecting handle to apply force, thereby playing the role of converting the connection mode, increasing the function of the wrench, and improving the practicality of the wrench.

[0017] Optionally, the first clearance groove extends through one side of the handle, and a transmission rod is fixedly connected to one end of the insertion rod that extends into the first clearance groove. The end of the transmission rod away from the insertion rod extends through the first clearance groove to the outside of the handle.

[0018] By adopting the above technical solution, a transmission rod extending through the first clearance groove and out of the handle is connected to one end of the insertion rod. This allows the operator to move the insertion rod by turning the transmission rod, causing the insertion rod to slide within the moving hole. This allows for free adjustment of whether the insertion rod is connected to the rotating column, making it more convenient for the operator to use and improving the portability of the wrench.

[0019] Optionally, a limiting hook is provided on the side wall of the first clearance groove away from the rotating column, and a limiting rope loop is provided on the transmission rod. When the transmission rod moves to the side away from the rotating column, the limiting rope loop is sleeved on the limiting hook.

[0020] By adopting the above technical solution, and by providing a limiting hook and a limiting rope loop, when the insert rod slides out of the moving hole, the limiting rope loop can be put on the limiting hook to fix the position of the insert rod, so that the insert rod will not slide back into the moving column, making the wrench mode switching more stable and improving the stability of the wrench.

[0021] Optionally, the fixing assembly further includes a second compression spring, one end of which abuts against the end of the insert rod away from the anti-rotation groove, and the other end of which abuts against the end of the first clearance groove away from the rotating column.

[0022] By adopting the above technical solution, and by installing a second compression spring in the fixed component, when the insertion rod slides out of the rotating hole and is fixed to the limiting hook by the limiting rope ring, the second compression spring is compressed. When the limiting rope ring is removed from the limiting hook, the second compression spring pulls the insertion rod back to slide into the moving hole and connects with and fixes it in the moving column. This makes the wrench switching mode more portable and improves the stability of the wrench switching mode.

[0023] Optionally, the conversion assembly further includes a limiting rod, which is fixedly connected to the insert rod and coaxially arranged with the insert rod. The second compression spring is sleeved on the limiting rod. The side wall of the first clearance groove away from the rotating column is provided with a second clearance groove. The end of the limiting rod away from the insert rod passes through the second clearance groove.

[0024] By adopting the above technical solution, a limiting rod is coaxially set on the insertion rod. When the insertion rod slides, the limiting rod is always inserted into the second clearance groove to fix the position of the insertion rod in the first clearance groove. This prevents the insertion rod from moving freely in the first clearance groove due to moving out of the rotating hole, thus ensuring the stability of the conversion component and improving the stability of the wrench mode conversion.

[0025] Optionally, the handle is provided with an insulating sleeve.

[0026] By adopting the above technical solution, and by providing an insulating sleeve on the handle, the wrench provides insulation during use, protecting the safety of the workers and improving the safety of the wrench.

[0027] In summary, this utility model has at least one of the following beneficial technical effects:

[0028] 1. By incorporating a rotating shaft and a fixing component, the angle between the wrench head and the connecting handle can be freely adjusted and fixed by the fixing component, enabling the wrench to be used in different working environments and improving its practicality;

[0029] 2. By providing a conversion component on the handle, the wrench's usability is improved by allowing the handle to switch between different usage modes depending on whether the insert rod is connected to the rotating column. Attached Figure Description

Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0037] This utility model discloses an adjustable power equipment installation tool.

[0038] Reference Figure 1An adjustable electrical equipment installation tool includes a wrench head 1, a connecting handle 2, an angle fixing module 3, a grip 4, and a conversion component 5. The wrench head 1 and the connecting handle 2 are rotatably connected to adjust their relative angle. The angle fixing module 3 is mounted on the wrench head 1 and the connecting handle 2 to fix their relative angle. The grip 4 is mounted on the end of the connecting handle 2 away from the wrench head 1 for easy gripping by the user. The conversion component 5 is mounted on the grip 4 to switch the mode of control for rotating the grip 4.

[0039] Reference Figure 1 and Figure 2 The angle fixing module 3 includes a rotating shaft 31, a first lug 32, a second lug 33, a third lug 34, and a fixing component 35. The first lug 32 and the second lug 33 are fixedly connected to the end of the connecting handle 2 away from the grip 4, and the first lug 32 and the second lug 33 are arranged opposite to each other. The third lug 34 is fixedly connected to the wrench head 1. The first lug 32 has a first through hole 321, the second lug 33 has a second through hole 331, and the third lug 34 has a third through hole 341. The rotating shaft 31 passes through the first through hole 321, the second through hole 331, and the third through hole 341 in sequence, so that the wrench head 1 and the connecting handle 2 can rotate relative to each other around the rotating shaft 31 to adjust the angle between the wrench head 1 and the connecting handle 2.

[0040] Reference Figure 2 and Figure 3 To fix the angle between the wrench head 1 and the connecting handle 2, the fixing assembly 35 includes a first gear 351 and a second gear 352. The first lug 32 has a first locking groove 322 on the side away from the second lug 33. The first gear 351 is fitted into the first locking groove 322 and engages with it, thus fixing the rotating shaft 31 and the first lug 32 relative to each other. The first lug 32 has a fitting groove 323 on the side closer to the second lug 33. The second gear 352 is placed in the fitting groove 323 to avoid contact with it. This fitting groove 323 can either mesh with the second gear 352 or be shaped like a circular hole 44. The third lug 34 has a second locking groove 342 on the side closer to the first lug 32. The second gear 352 is fitted into the second locking groove 342 and engages with it, thus fixing the rotating shaft 31 and the third lug 34 relative to each other.

[0041] Reference Figure 2 and Figure 3To unlock the angle between the wrench head 1 and the connecting handle 2, the fixing assembly 35 also includes a pressing plate 353 and a first compression spring 354. The pressing plate 353 is fixedly connected to the end of the rotating shaft 31 away from the first gear 351, and is used to drive the rotating shaft 31 to move towards the side of the first lug 32 away from the second lug 33. The first compression spring 354 is sleeved on the rotating shaft 31, with one end of the first compression spring 354 abutting against the side of the pressing plate 353 near the second lug 33, and the other end of the first compression spring 354 abutting against the side of the second lug 33 away from the first lug 32. When it is necessary to adjust the angle between the wrench head 1 and the connecting handle 2, pressing the pressing plate 353 will extend the first gear 351 from the first locking groove 322 and the second gear 352 from the second locking groove 342, and compress the first compression spring 354. After adjusting the angle by rotating the wrench head 1, releasing the pressing plate 353 will fix the first gear 351 in the first locking groove 322 and the second gear 352 in the second locking groove 342 under the action of the first compression spring 354, thus fixing the angle between the wrench head 1 and the connecting handle 2.

[0042] Reference Figure 4 and Figure 5 The end of the connecting handle 2 away from the wrench head 1 is fixedly connected to a rotating post 21. The handle 4 has a rotating hole 41, and the rotating post 21 passes through the rotating hole 41, so that the handle 4 can rotate around the rotating post 21.

[0043] Reference Figure 4 and Figure 5 To allow the handle 4 and the rotating post 21 to be switched between a fixed connection and a rotatable connection, the conversion assembly 5 includes a plug 51. The side wall of the rotating hole 41 has a movable hole 411, and the plug 51 is slidably connected within the movable hole 411. The rotating post 21 has an anti-rotation groove 211, and one end of the plug 51 extending out of the movable hole 411 is embedded in the anti-rotation groove 211, thus fixing the handle 4 and the rotating post 21. The handle 4 has a first clearance groove 42, allowing the plug 51 to slide completely into the movable hole 411 without entering the rotating hole 41.

[0044] Reference Figure 4 and Figure 5 To facilitate movement of the insertion rod 51, a transmission rod 511 is fixedly connected to the insertion rod 51. Here, the transmission rod 511 is located at the end of the insertion rod 51 away from the anti-rotation groove 211. The end of the transmission rod 511 away from the insertion rod 51 extends beyond the handle 4. A limiting rope ring 5111 is also fixedly connected to the transmission rod 511. A limiting hook 421 is fixedly connected to the side wall of the first clearance groove 42 away from the rotating column 21. When the transmission rod 511 moves to the side away from the rotating column 21, the limiting rope ring 5111 is sleeved on the limiting hook 421 to fix the position of the insertion rod 51.

[0045] Reference Figure 4 and Figure 5 The conversion component 5 also includes a limiting rod 52, which is fixedly connected to the insertion rod 51 and coaxially arranged with it. The side wall of the first clearance groove 42 away from the rotating column 21 has a second clearance groove 422. The end of the limiting rod 52 away from the insertion rod 51 passes through the second clearance groove 422. When the insertion rod 51 moves in the first clearance groove 42, the limiting rod 52 is always in the second clearance groove 422 to fix the position of the insertion rod 51, so that the insertion rod 51 does not deviate from its original movement trajectory when moving. In order to facilitate driving the insertion rod 51 closer to the rotating column 21, a second compression spring 521 is also sleeved on the limiting rod 52. When the insertion rod 51 moves away from the rotating column 21, the second compression spring 521 is compressed. When the limiting rope ring 5111 is removed from the limiting hook 421, the insertion rod 51 can be inserted into the anti-rotation groove 211 under the restoring force of the second compression spring 521.

[0046] Combination Figure 1 The handle 4 is also covered with an insulating sleeve 43 to prevent electric shock to the operator when holding the handle 4, thus protecting the operator's safety. The handle 4 also has a round hole 44 for easy hanging of the wrench.

[0047] The implementation principle of an adjustable power equipment installation tool according to this utility model embodiment is as follows: When the worker wants to adjust the angle between the wrench head 1 and the connecting handle 2, pressing the pressing plate 353 will extend the first gear 351 from the first locking groove 322 and extend the second gear 352 from the second locking groove 342 into the embedding groove 323, thereby unlocking; after adjusting the angle by rotating the wrench head 1 or the connecting handle, releasing the pressing plate 353 will allow the elastic force generated by the first compression spring 354 to embed and fix the first gear 351 in the first locking groove 322 and the second gear 352 in the second locking groove 342, thereby fixing the angle between the wrench head 1 and the connecting handle 2. When it is necessary to connect the relative rotation between handle 2 and grip 4, pull the transmission rod 511 and fix the limiting rope ring 5111 on the limiting hook 421. The insertion rod 51 moves out of the rotating column 21 and returns to the moving hole 411. At this time, the grip 4 can rotate around the rotating column 21. When it is necessary to connect the relative fixation between handle 2 and grip 4, when the limiting rope ring 5111 is taken out from the limiting hook 421, the insertion rod 51 automatically returns to the anti-rotation groove 211 of the rotating column 21 under the action of the second compression spring 521. At this time, the grip 4 is relatively fixed to the rotating column 21.

[0048] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
