Description

Technical Field

[0001] This utility model relates to the field of bolt disassembly technology, specifically a single-hand disassembly device. Background Technology

[0002] High-altitude work generally refers to work performed at a height, with a person at a certain position as a reference. In the machinery industry, the scope of high-altitude work is quite extensive. We often see it in daily life; for example, installing or removing air conditioner outdoor units at height requires using bolts to fix or remove the mounting brackets used for the air conditioner outdoor units. Although safety precautions are in place before high-altitude work, it is extremely dangerous. Current installation methods basically involve workers manually aligning the bolts and nuts while ensuring the mounting bracket's position doesn't change. This is impossible for a single person to operate quickly. Therefore, how to enable workers to quickly and efficiently install or remove bolts has become an urgent problem to be solved. Utility Model Content

[0003] To address the above problems, this utility model provides a one-handed disassembly device, thus solving the aforementioned issues.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a single-hand disassembly device, comprising a snap-fit ​​cylinder, a sleeve rotatably connected to the left end of the snap-fit ​​cylinder, a handle fixedly connected to the snap-fit ​​cylinder at the left end of the sleeve, a bolt snapped into the right end of the snap-fit ​​cylinder, a nut connected to the right end of the bolt, two plates clamped and fixed between the bolt and the nut, a connector fixed on the sleeve, one end of the connector fixedly connected to the sleeve, and the other end of the connector connected to the nut.

[0005] Preferably, the snap-fit ​​cylinder has an internal cavity, within which a limit frame and a fixing frame are fixed. The fixing frame is located at the left end of the limit frame, and multiple prisms are slidably connected to the limit frame. One end of multiple telescopic hoses is fixed to the fixing frame, and the other end of each telescopic hose is fixedly connected to a prism. A piston is provided at the left end of the fixing frame and slidably connected to the cavity. The space between the piston and the telescopic hose is an oil chamber. A spring is fixed at the left end of the piston, and the left end of the spring is fixedly connected to the snap-fit ​​cylinder. An air hole is provided on the snap-fit ​​cylinder, and the air hole communicates with the internal cavity of the snap-fit ​​cylinder.

[0006] Preferably, the prism is a multi-faceted prism, and there are small gaps between each pair of the multiple prisms.

[0007] Preferably, the connector includes a bandage, one end of which is fixedly connected to the sleeve, and the other end of which is wrapped and fixedly connected to the nut.

[0008] Preferably, the connector includes a fixing plate, which is fixedly connected to the bandage. A connecting plate is detachably connected to the lower end of the fixing plate, and a vertical plate is detachably connected to the connecting plate. A snap-fit ​​block is fixed to the upper end of the vertical plate, and the snap-fit ​​block snaps into a nut.

[0009] Preferably, both the fixing plate and the vertical plate have multiple through holes, and both ends of the connecting plate are fixed with fixing bolts. The fixing plate and the vertical plate are fixedly connected to the connecting plate by fixing bolts.

[0010] Preferably, a reinforcing rib is fixed on the connecting plate, and the reinforcing rib is located at the right end of the fixing plate and fits against the right end face of the fixing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The bolt is clamped by the clamping sleeve, and the sleeve and nut are connected by the connector. The handle can be turned with one hand to facilitate the disassembly of the bolt and nut. When the handle is turned to disassemble the bolt and nut, the connector is obstructed by the plate. When the handle is turned, the plate blocks the connector from rotating, preventing the connector from rotating with the handle, thus realizing the disassembly of the bolt and nut with one hand.

[0013] 2. By using different numbers of prisms for telescopic movement, the remaining prisms engage and fix with the bolts, making the device suitable for bolts of different specifications. When connecting the clamping cylinder and the bolt, the plate is inserted into the cavity of the clamping cylinder. The plate moves against the prisms, and the prisms compress the corresponding telescopic hoses, squeezing the liquid in the telescopic hoses into the oil chamber, causing the piston to move and compress the spring. At this time, the remaining prisms engage with the bolts, thus fixing them. Attached Figure Description

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] Please see Figure 1 , Figure 2 and Figure 3 A one-handed disassembly device includes a snap-fit ​​cylinder 1. A sleeve 11 is rotatably connected to the left end of the snap-fit ​​cylinder 1. A handle 12, fixedly connected to the snap-fit ​​cylinder 1, is located at the left end of the sleeve 1. A bolt 4 is snapped into the right end of the snap-fit ​​cylinder 1. A nut 41 is connected to the right end of the bolt 4. Two plates 3 are clamped and fixed between the bolt 4 and the nut 41. A connector is fixed to the sleeve 11. One end of the connector is fixedly connected to the sleeve 11, and the other end is connected to the nut 41. The bolt 4 is snapped into the snap-fit ​​cylinder 1, and the sleeve 11 and the nut 41 are connected by the connector. The bolt 4 and nut 41 can be disassembled by rotating the handle 12 with one hand. When the handle 12 is rotated to disassemble the bolt 4 and nut 41, the connector is obstructed by the plates 3. The plates 3 prevent the connector from rotating, thus preventing the connector from rotating in tandem with the handle 12, thereby enabling one-handed disassembly of the bolt 4 and nut 41.

[0021] Please see Figure 1 , Figure 2 and Figure 3The snap-fit ​​cylinder 1 has an internal cavity, within which a limit frame 13 and a fixing frame 14 are fixed. The fixing frame 14 is located at the left end of the limit frame 13. Multiple prisms 131 are slidably connected to the limit frame 13. One end of multiple telescopic hoses 141 is fixed to the fixing frame 14, and the other end of each telescopic hose 141 is fixedly connected to a prism 131. A piston 15 is slidably connected to the cavity at the left end of the fixing frame 14. The space between the piston 15 and the telescopic hoses 141 is an oil chamber. Liquid is injected into the oil chamber, allowing the telescopic hoses 141 to return to their original position when the liquid is squeezed, thereby causing the prisms 131 to extend and return to their original position. A spring 16 is fixed to the left end of the piston 15, and the left end of the spring 16 is fixedly connected to the snap-fit ​​cylinder 1. When connecting the snap-fit ​​cylinder 1 and the bolt 4, the bolt 4 is inserted into the cavity of the snap-fit ​​cylinder 1, and the bolt 4 moves against the prisms 131. The piston 15 is compressed against the corresponding telescopic hose 141, squeezing the liquid in the telescopic hose 141 into the oil chamber, causing the piston 15 to move and compress the spring 16. At this time, the remaining prism 131 engages with the bolt 4, thus fixing the bolt 4. The clamping cylinder 1 has an air hole 17, which connects to the cavity inside the clamping cylinder 1. The prism 131 is a multi-prism shape, with small gaps between each pair of prisms 131. By setting gaps between each pair of prisms 131, when the bolt 4 moves against the prisms 131, it prevents the prisms 131 from affecting each other. At the same time, when the prisms 131 return to their original position, the spring 16 pushes against the piston 15 to move, and at the same time, external air enters the cavity of the clamping cylinder 1 through the air hole 17. The piston 15 squeezes the liquid in the oil chamber into the telescopic hose 141, and the telescopic hose 141 moves against the prism 131 to return to its original position.

[0022] Example 1:

[0023] Please see Figure 1 , Figure 2 and Figure 3 The connector includes a bandage 21, one end of which is fixedly connected to the sleeve 11, and the other end of which is wrapped and fixedly connected to the nut 41. In use, the other end of the bandage 21 is wrapped around the nut 41 and tightened, and then the handle 12 is held and rotated. When the handle 12 is rotated to disassemble the bolt 4 and the nut 41, the bandage 21 is obstructed by the plate 3. When the handle 12 is rotated, the plate 3 blocks the bandage 21 from rotating, preventing the bandage 21 from rotating with the handle 12, thereby realizing the disassembly of the bolt 4 and the nut 41 with one hand.

[0024] Example 2:

[0025] Please see Figure 1 , Figure 2 and Figure 4The connector includes a fixing plate 22, which is fixedly connected to the bandage 21. A connecting plate 221 is detachably connected to the lower end of the fixing plate 22, and a vertical plate 222 is detachably connected to the connecting plate 221. A snap-fit ​​block 223 is fixed to the upper end of the vertical plate 222, and the snap-fit ​​block 223 snaps into the nut 41. Both the fixing plate 22 and the vertical plate 222 have multiple through holes 225. The fixing plate 22 and the vertical plate 222 are adjusted according to the bolt 4 and the distance from the bolt 4 to the edge of the plate 3, so that the connecting plate 221 fits snugly against the edge of the plate 3. After adjustment, they are fixed by a fixing bolt 224 to prevent the connecting plate 221 from detaching from the fixing plate 22 and the vertical plate 222. Simultaneously, the snap-fit ​​block 223 snaps into the nut. 41 is engaged to prevent the nut 41 from rotating synchronously when the bolt 4 is rotated. The left and right ends of the connecting plate 221 are fixed with fixing bolts 224. The fixing plate 22 and the vertical plate 222 are fixedly connected to the connecting plate 221 through fixing bolts 224. The connecting plate 221 is fixed with a reinforcing rib. The reinforcing rib is located at the right end of the fixing plate 22 and is in contact with the right end face of the fixing plate 22. When the handle 12 is rotated to disassemble the bolt 4 and the nut 41, the connecting plate 221 is obstructed by the plate 3. When the handle 12 is rotated, the plate 3 blocks the connecting plate 221 from rotating, preventing the connecting plate 221 and the handle 12 from rotating together, thereby realizing the disassembly of the bolt 4 and the nut 41 with one hand.

[0026] When this utility model is put into use:

[0027] Insert the bolt 4 into the cavity of the snap-fit ​​cylinder 1. The bolt 4 moves against the prism 131, and the prism 131 compresses the corresponding telescopic hose 141, squeezing the liquid in the telescopic hose 141 into the oil chamber, causing the piston 15 to move and compress the spring 16. At this time, the remaining prism 131 engages with the bolt 4, thus fixing the bolt 4. After completion, wrap the other end of the bandage 21 around the nut 41 and tighten it. Then, hold the handle 12 and rotate it. When rotating the handle 12 to disassemble the bolt 4 and the nut 41, the bandage 21 is obstructed by the plate 3. When rotating the handle 12, the plate 3 blocks the bandage 21 from rotating, preventing the bandage 21 from rotating with the handle 12, thus enabling the bolt 4 and the nut 41 to be disassembled with one hand.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
