Description

Technical Field

[0001] The utility model relates to the technical field of automobile maintenance, in particular to a bolt disassembly device for automobile maintenance. Background Art

[0002] During the maintenance of a car, it is sometimes necessary to remove the internal parts from the car. During the removal process, the bolts are removed. The existing method of removing the bolts of a car is mainly to hold the outer hexagon of the bolt end with an outer hexagon wrench, then apply force to screw it out, and then remove the parts;

[0003] However, the existing hexagonal wrench can only be used to disassemble the hexagonal bolts of fewer specifications. If the specifications do not match, it is necessary to replace it with a hexagonal wrench of the corresponding specifications to twist and disassemble it. This frequent replacement of wrenches not only wastes the time of maintenance personnel, but also reduces the efficiency of maintenance personnel in automobile maintenance. Therefore, it is necessary to provide a bolt disassembly device for automobile maintenance to solve the above technical problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5The utility model provides an embodiment: a bolt removal device for automobile maintenance, including a connecting arm 1 and a handle plate 2, the handle plate 2 is installed below the connecting arm 1, and an adjustment mechanism 3 is distributed inside the handle plate 2, and a driving shaft 4 is movably connected to the inside of the connecting arm 1. Example 1

[0021] See also Figure 1-4 A sleeve hole 201 is provided inside one side of the handle plate 2, and a slide groove 202 is opened inside the handle plate 2. The adjusting mechanism 3 includes a slider 301 connected to the inner side of the handle plate 2, and a screw rod 302 is threadedly connected to the middle of the slider 301, and a clamping block 303 is installed at the end of the slider 301. The slider 301 and the handle plate 2 form a sliding structure, and a first bevel gear 401 is installed on the outer side of the drive shaft 4, and a second bevel gear 402 is meshed on the outer side of the first bevel gear 401. A knob 403 is connected to the end of the drive shaft 4, but the sizes of the hexagonal bolts on the car are different. In order to make the wrench suitable for hexagonal bolts of different sizes, the knob 403 can be manually rotated to make the knob 403 drive the drive shaft 4 and the screw rod 302 at the lower end to rotate, thereby driving the corresponding slider 301 to cooperate with the blind groove inside the handle plate 2 to slide close to the center of the handle plate 2, thereby driving the clamping block 303 at the end of the slider 301 to move in the same direction. Example 2

[0022] See also Figure 4-5 , which is different from Example 1, is that a first bevel gear 401 is installed on the outside of the driving shaft 4, and a second bevel gear 402 is meshed on the outside of the first bevel gear 401, and a knob 403 is connected to the end of the driving shaft 4, and the second bevel gear 402 and the slide groove 202 form an annular sliding structure. When the driving shaft 4 rotates, it can also drive the first bevel gear 401 to rotate. The rotation of the first bevel gear 401 can effectively drive the second bevel gear 402 to rotate. Under the action of the rotation of the second bevel gear 402, the other five second bevel gears 402 can rotate at the same time, thereby driving all the screw rods 302 to rotate at the same time. When all the screw rods 302 rotate, they can drive all the sliders 301 and the clamping blocks 303 to move toward the center of the handle plate 2 at the same time, so that the six clamping blocks 303 can effectively clamp and twist the outside of the end of the external hexagonal bolt.

[0023] Working principle: Figure 1-5 As shown, when inspecting the interior of a car, it is necessary to remove the bolts on the car. The existing method of removing the bolts of a car is mainly to tighten the outer hexagon of the end of the stud bolt with an inner hexagon wrench, and then rotate and apply force to screw it out;

[0024] However, the sizes of the hexagonal bolts on the car are different. In order to make the wrench suitable for the hexagonal bolts of different sizes, the knob 403 can be manually rotated to make the knob 403 drive the drive shaft 4 and the screw rod 302 at the lower end to rotate, thereby driving the corresponding slider 301 to cooperate with the blind groove inside the handle plate 2 to slide close to the center of the handle plate 2, thereby driving the clamping block 303 at the end of the slider 301 to move in the same direction;

[0025] At the same time, when the driving shaft 4 rotates, it can also drive the first bevel gear 401 to rotate, and the rotation of the first bevel gear 401 can effectively drive the second bevel gear 402 to rotate. Under the action of the rotation of the second bevel gear 402, the other five second bevel gears 402 can be rotated at the same time, so that all the screw rods 302 can be driven to rotate at the same time. When all the screw rods 302 rotate, all the sliders 301 and the clamping blocks 303 can be driven to move toward the center of the handle plate 2 at the same time, so that the six clamping blocks 303 can effectively clamp and twist the outer side of the end of the external hexagonal bolt;

[0026] In summary, the bolt removal wrench for automobile maintenance can be suitable for hexagonal bolts of different specifications. During the disassembly process, there is no need to frequently replace the wrench, thereby improving the efficiency of automobile maintenance.
