Description

Technical Field

[0001] This utility model relates to the field of wrench technology, specifically a bolt clamping tool. Background Technology

[0002] A socket wrench is generally called a socket. It consists of multiple sockets with hexagonal or dodecagonal holes and is equipped with a handle, extension bar, and other accessories. It is especially suitable for tightening bolts or nuts in very narrow or deeply recessed positions.

[0003] In existing technologies, bolts in some parts of large equipment are limited by space, such as coal bunker chutes and inside hoist skips. For example, when replacing the fixing bolts of the lining plates of hoist skips or coal bunker chutes, since the bolts all protrude from the inside of the container to the outside, it is necessary for operators to enter the skip or coal chute. This is not only laborious and poses a safety hazard, but also lacks lighting inside, making it difficult to accurately install wrenches and inconvenient to use. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 This utility model discloses a bolt clamping tool, including an outer cylinder 1. The left side of the outer cylinder 1 is open. A handle 2 is fixedly installed on the left side of the outer cylinder 1. An illumination mechanism 3 is provided between the handle 2 and the front and rear sides of the outer cylinder 1. A plug assembly 4 is fixedly installed on the right side of the outer cylinder 1. An internal hexagon socket 5 is snapped onto the right side of the plug assembly 4. Both the plug assembly 4 and the internal hexagon socket 5 adopt the structure of an existing socket wrench. A grip 6 is fixedly installed on the lower surface of the handle 2 near the left side. A driving mechanism 7 is provided between the grip 6 and the outer cylinder 1. A transmission rod 9 is installed on the upper surface of the driving mechanism 7 through a first pin assembly 8. The right end of the transmission rod 9 is inserted into the upper side wall of the outer cylinder 1. The transmission rod 9 is connected to a clamping mechanism 10. The clamping mechanism 10 is installed on the outer surface of the outer cylinder 1 at a position corresponding to the internal hexagon socket 5.

[0021] Specifically, the lighting mechanism 3 includes a battery 301, a switch button 302, and a lamp 303. The battery 301 is installed inside the handle 2. The switch button 302 is embedded in the upper side wall of the outer cylinder 1 near the left side. The lamp 303 is installed on the front and rear sides of the outer cylinder 1 near the right edge. The battery 301, the switch button 302, and the lamp 303 are electrically connected in sequence.

[0022] In this embodiment, when the switch button 302 is turned on, the battery 301 is powered by the light 303, and the light 303 illuminates the right side of the internal hexagonal sleeve 5.

[0023] Specifically, a plug 11 is threadedly installed on the front side of the handle 2 corresponding to the battery 301, and a wire hole 12 is opened on the right side wall of the handle 2 at the position corresponding to the outer cylinder 1.

[0024] In this embodiment, opening the plug 11 facilitates the inspection or charging of the battery 301 inside the handle 2.

[0025] Specifically, the transmission rod 9 has a Z-shaped structure, and the upper side wall of the outer cylinder 1 corresponding to the transmission rod 9 has a first rectangular opening 13.

[0026] In this embodiment, the first rectangular opening 13 satisfies the requirement for the transmission rod 9 to move left and right.

[0027] Specifically, the drive mechanism 7 includes a second pin assembly 701, a pressure handle 702, a spring 703, and a second rectangular opening 704. The second pin assembly 701 is installed on the lower surface of the outer cylinder 1 near the front and rear positions, and the pressure handle 702 is installed on the front and rear second pin assemblies 701. The left side of the pressure handle 702 near the lower side position is connected to the right side of the handle 6 near the lower side position by the spring 703. The second rectangular opening 704 is opened on the lower side wall of the outer cylinder 1 corresponding to the pressure handle 702.

[0028] In this embodiment, the spring 703 pushes the lower part of the pressure handle 702 to move to the right along the second pin assembly 701, so that the upper end of the pressure handle 702 drives the transmission rod 9 to the left end through the first pin assembly 8, and the transmission rod 9 drives the clamping mechanism 10 to clamp the right side of the internal hexagonal sleeve 5.

[0029] Specifically, the clamping mechanism 10 includes a third pin assembly 101, a U-shaped frame 102, a fourth pin assembly 103, a clamping plate 104, and a rectangular notch 105. The third pin assembly 101 is respectively installed on the front and rear sides of the outer cylinder 1, and a U-shaped frame 102 is installed between the front and rear third pin assemblies 101. The fourth pin assembly 103 is installed at the upper edge of the front and rear side walls of the U-shaped frame 102, and the fourth pin assembly 103 is connected to the right end of the transmission rod 9. A clamping plate 104 is fixedly installed at the lower edge of the right side of the U-shaped frame 102, and a rectangular notch 105 is provided on the right side wall of the clamping plate 104.

[0030] In this embodiment, the upper end of the U-shaped frame 102 moves to the right along the transmission rod 9 via the fourth pin assembly 103. At this time, the U-shaped frame 102 rotates along the third pin assembly 101, so that the clamping plate 104 on the lower right side of the U-shaped frame 102 is clamped on the right side of the internal hexagonal sleeve 5, thereby achieving the effect of clamping the bolt.

[0031] Specifically, the clamping plate 104 is an L-shaped structure placed horizontally.

[0032] In this embodiment, the clamping plate 104 can effectively clamp the internal bolts of the hexagon socket sleeve 5.

[0033] In use, select the corresponding hex socket 5 according to the bolt specifications and install it on the connector assembly 4. The pressure handle 702 in the drive mechanism 7 is held by hand, causing the lower end of the pressure handle 702 to rotate along the second pin assembly 701. At this time, the upper end of the pressure handle 702 drives the transmission rod 9 to move to the right via the first pin assembly 8. The transmission rod 9 drives the fourth pin assembly 103 in the clamping mechanism 10 to move to the right, causing the fourth pin assembly 103 to drive the U-shaped frame 102 along the third pin. When component 101 rotates, the lower end of the U-shaped frame 102 drives the clamping plate 104 to open downwards, placing the bolt into the internal hex socket 5. The pressure handle 702 is then released, and the spring 703 pushes the lower position of the pressure handle 702 along the second pin assembly 701 to the right. This causes the upper end of the pressure handle 702 to drive the transmission rod 9 to the left end via the first pin assembly 8. The transmission rod 9 then drives the fourth pin assembly 103 to move to the left, causing the fourth pin assembly 103 to drive the U-shaped frame 102 along the first pin assembly 701. The three-pin assembly 101 rotates, and the lower end of the U-shaped frame 102 drives the clamping plate 104 to clamp the right side of the internal hexagonal socket 5. The clamping plate 104 clamps the bolt inside the internal hexagonal socket 5. The operator can send the bolt to the installation position through the opening or observation hole. The switch button 302 in the lighting mechanism 3 is turned on to power the light 303 in the battery 301. The light 303 illuminates the right side of the internal hexagonal socket 5, making it easier to see the bolt installation position. The handle 2 drives the outer cylinder 1 to rotate, and the outer cylinder 1 drives the bolt inside the internal hexagonal socket 5 to rotate through the plug assembly 4, thus installing the bolt. After installation, the clamping plate 104 is opened to remove the bolt, completing the installation. This reduces the time that operators spend working inside containers such as coal bunker chutes and hoist skips, reduces the chance of injury, eliminates unnecessary safety hazards, greatly improves work efficiency, and allows for clear viewing of the bolt position, making it convenient to use.

[0034] In summary, this bolt clamping tool adds the function of clamping bolts to a wrench, reduces the time workers spend inside containers such as coal bunker chutes and hoist skips, lowers the chance of injury, eliminates unnecessary safety hazards, improves work efficiency, and adds lighting to clearly show the bolt position, making it easier to use.

[0035] 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.
