Description

Technical Field

[0001] This application relates to the field of hand tool technology, and more particularly to a wrench. Background Technology

[0002] After the sliding door components are assembled, the height of the hinges in the sliding door needs to be adjusted in the vertical direction to ensure uniform gaps and surface differences after the whole vehicle is assembled. However, due to the small gap around the locking nut of the hinge in the sliding door, when the tool enters between the sliding door and the body to tighten the locking nut, it is easy to interfere with the door or body due to the small space, making it difficult to adjust the height of the hinges in the vertical direction. Utility Model Content

[0003] This application provides a wrench that reduces interference between the wrench and the car door or body, and enables adjustment of the car door's position in the vertical direction.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include:

[0005] This application provides a wrench, which includes a handle and a head. The handle extends along a first direction; the head is located at one end of the handle along the first direction and extends along a second direction. The angle between the first direction and the second direction is α, which satisfies: 18°≤α≤30°.

[0006] The wrench proposed in this application embodiment has a handle extending in a first direction and a head extending in a second direction, with the head and handle connected at an angle. When using the wrench to adjust the position of the car door in the vertical direction, the head of the wrench can be inserted between the car door and the car body, and the head cooperates with the locking component. By rotating the handle, the locking state and locking position of the locking component can be adjusted. Since there is an angle between the handle and the head of the wrench during the entire adjustment process, and an angle between the handle and the car body or car door when adjusting the state of the locking component, there will be no interference with the car body or car door, thereby realizing the adjustment of the car door's position in the vertical direction.

[0007] Optionally, the angle α between the first direction and the second direction is 20°.

[0008] In the above embodiment, when the head of the wrench is inserted between the door and the body, and the handle of the wrench is rotated clockwise or counterclockwise to adjust the position of the locking component, there is a gap between the handle and the body or door, which can reduce the interference between the handle and the door and the body, and realize the adjustment of the door's position in the vertical direction.

[0009] Optionally, the head includes a connected body portion and a tightening portion. The body portion is connected to the handle. Along the second direction, the tightening portion has a first end and a second end disposed opposite to each other. The first end is connected to the body portion, and the thickness of the first end is greater than the thickness of the second end.

[0010] In the above embodiment, when the head is inserted between the vehicle body and the door, the second end first enters the space where the locking component is located. Since the thickness of the second end is smaller, the head of the wrench can more easily enter the space where the locking component is located, thereby improving work efficiency.

[0011] Optionally, the thickness of the tightening portion gradually decreases from the first end to the second end.

[0012] In the above embodiments, the thickness gradient design provides guidance for the tightening part to enter the space where the locking member is located, making it easier for the tightening part to enter the space where the locking member is located.

[0013] Optionally, the tightening part has an opening for receiving a locking member, and the tightening part is provided with retractable teeth that selectively extend into the opening.

[0014] In the above embodiment, when the handle of the wrench is turned clockwise, the tightening part rotates the locking member, and the teeth extend into the opening and press against the locking member, thereby realizing the rotation of the locking member; when the tightening part is turned counterclockwise, the handle of the wrench is turned in the opposite direction, and the reverse force of the locking member pushes the teeth to retract, thereby realizing the effect of reverse free rotation and reset, so that the tightening part has both the function of clamping the locking member and quick advance and quick retreat.

[0015] Optionally, the teeth have a third end, which is rotatably connected to the tightening part; the wrench further includes an elastic element, which has a fourth end and a fifth end disposed opposite to each other, the fourth end being connected to the tightening part, the fifth end being connected to the teeth, and the fifth end being spaced apart from the third end.

[0016] In the above embodiment, when the tightening part is turned counterclockwise, the handle of the wrench is rotated in the opposite direction, and the reverse force of the locking member pushes the teeth to press against the elastic member and retract, achieving the effect of reverse free rotation and reset; when the handle of the wrench is rotated clockwise, the tightening part rotates the locking member, and the rotational torque of the tightening part is transmitted to the locking member through the teeth. The elastic member presses against the teeth that extend into the opening, and the teeth press against the locking member, thereby realizing the rotation of the locking member.

[0017] Optionally, the teeth may extend into a first surface and a second surface of the opening, the first surface and the second surface being connected and angled together. When the wrench is rotated clockwise, the locking member applies force to the first surface to cause the teeth to extend into the opening; when the wrench is rotated counterclockwise, the locking member applies force to the second surface to cause the teeth to retract.

[0018] Optionally, along the first direction, one end of the handle is connected to the head, and the other end is provided with an anti-slip part. Attached Figure Description

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0036] After the sliding door components are assembled, the height of the hinges in the vertical direction needs to be adjusted to ensure uniform surface differences after assembly. Currently, the method for adjusting the height of the hinges in the vertical direction is as follows: First, loosen the locking nuts in the vertical direction of the hinges counterclockwise, allowing the hinge's main shaft pin to be in a released and rotatable state. Adjust the bolt head of the main shaft pin; clockwise rotation lowers the door's position, and counterclockwise rotation raises it. After the door is adjusted, tighten the locking nuts in the vertical direction. However, due to the small gap around the locking nuts of the sliding door hinges, tools can easily interfere with the door or body when tightening the locking nuts between the sliding door and the body, making it difficult to adjust the height of the hinges in the vertical direction.

[0037] In view of this, this application provides a wrench that can be easily accessed in the working space between the car door and the car body, and can adjust the position of the car door in the vertical direction.

[0038] This application provides a wrench, as shown in the embodiments below. Figure 1 and Figure 2 The wrench includes a handle 1 and a head 2. The handle 1 extends along a first direction X. The head 2 is located at one end of the handle 1 along the first direction X and extends along a second direction Y. The angle between the first direction X and the second direction Y is α, which satisfies: 18°≤α≤30°.

[0039] The wrench proposed in this embodiment has a handle 1 extending along a first direction X and a head 2 extending along a second direction Y. The head 2 and the handle 1 are connected at an angle. When the wrench is used to adjust the position of the car door in the vertical direction, the head 2 of the wrench can be inserted between the car door and the car body. The handle 1 of the wrench is outside the car door, and the head 2 cooperates with the locking member. By rotating the handle 1, the locking state and locking position of the locking member can be adjusted. Since there is an angle between the handle 1 and the head 2 of the wrench during the entire adjustment process, there is an angle between the handle 1 and the car body or car door when adjusting the state of the locking member. Therefore, the handle 1 will not interfere with the car body or car door, thereby realizing the adjustment of the position of the car door in the vertical direction.

[0040] If the distance between handle 1 and head 2 is too small, handle 1 will interfere with the vehicle body when the state of the locking component is changed using a wrench. If the distance between handle 1 and head 2 is too large, handle 1 will interfere with the door when the state and locking position of the locking component are changed using a wrench.

[0041] For example, the locking element is a locking nut, which can be constructed as an 18-faced nut, and the wrench rotates the locking nut by 20° each time. Using the wrench described in this application, the locking element can be adjusted in confined spaces, thereby adjusting the vertical position of the vehicle door.

[0042] Optionally, refer to Figure 1 The angle α between the first direction X and the second direction Y is 20°. The angle between the handle 1 and the head 2 is 20°. When the head 2 of the wrench is inserted between the door and the body, and the handle 1 of the wrench is rotated clockwise or counterclockwise to adjust the position of the locking part, there is a gap between the handle 1 and the body or door, which can reduce the interference between the handle 1 and the door and the body, and realize the adjustment of the door's position in the vertical direction.

[0043] Optionally, refer to Figure 1 The head 2 includes a connected body part 21 and a tightening part 22. The body part 21 is connected to the handle 1. Along the second direction Y, the tightening part 22 has a first end 221 and a second end 222 that are disposed opposite to each other. The first end 221 is connected to the body part 21, and the thickness of the first end 221 is greater than the thickness of the second end 222.

[0044] Along the second direction Y, the second end 222 of the tightening part 22 is located on the side away from the main body 21. When the head 2 is inserted between the vehicle body and the door, the second end 222 first enters the space where the locking member is located. Since the thickness of the second end 222 is small, the head 2 of the wrench can more easily enter the space where the locking member is located, thereby improving the work efficiency.

[0045] It should be noted that the thickness of the first end 221 and the thickness of the second end 222 are along the thickness direction of the head 2, and the dimensions of the first end 221 and the second end 222 are also mentioned. The thickness direction of the head 2 is perpendicular to the first direction X and the second direction Y.

[0046] Optionally, refer to Figure 1 From the first end 221 to the second end 222, the thickness of the tightening part 22 gradually decreases. The gradual decrease in thickness of the tightening part 22 makes the second end 222 of the tightening part 22 the point of minimum thickness. The design of the gradual thickness change provides guidance for the tightening part 22 to enter the space where the locking member is located, making it easier for the tightening part 22 to enter the space where the locking member is located.

[0047] Optionally, refer to Figure 1 and Figure 3 The tightening part 22 has an opening 223 for accommodating the locking element, and the tightening part 22 is provided with a retractable tooth 3, which selectively extends into the opening 223.

[0048] The toothed part 3 is located in the tightening part 22. When the handle 1 of the wrench is turned clockwise, the tightening part 22 rotates the locking part. The rotational torque of the tightening part 22 is transmitted to the locking part through the toothed part 3. The toothed part 3 extends into the opening 223 and presses against the locking part, thereby realizing the rotation of the locking part. When the tightening part 22 is turned counterclockwise, the handle 1 of the wrench is turned in the opposite direction. The reverse force of the locking part pushes the toothed part 3 to retract, thereby realizing the effect of reverse free rotation and reset. This allows the tightening part 22 to have both the function of clamping the locking part and the function of quick advance and quick retreat.

[0049] Optionally, refer to Figure 3 The toothed part 3 has a third end 31, which is rotatably connected to the tightening part 22; the wrench also includes an elastic element 4, which has a fourth end 41 and a fifth end 42 arranged opposite to each other. The fourth end 41 is connected to the tightening part 22, and the fifth end 42 is connected to the toothed part 3. The fifth end 42 and the third end 31 are spaced apart.

[0050] Specifically, the tightening part 22 has a cavity, the third end 31 of the toothed part 3 is located in the cavity, the elastic element 4 is located in the cavity, the fourth end 41 of the elastic element 4 is connected to the tightening part 22, and the fifth end 42 is connected to the toothed part 3. The fifth end 42 is spaced apart from the third end 31, so that when the handle 1 of the wrench is turned clockwise, the tightening part 22 rotates the locking part, and the rotational torque of the tightening part 22 is transmitted to the locking part through the toothed part 3. The elastic element 4 presses against the toothed part 3 and extends into the opening 223, and the toothed part 3 presses against the locking part, realizing the rotation of the locking part. When the tightening part 22 is turned counterclockwise, the handle 1 of the wrench is turned in the opposite direction, and the reverse force of the locking part pushes the toothed part 3 to press against the elastic element 4 and retract, realizing the effect of reverse rotation and reset. That is, the tightening part 22 has both the function of locking the locking part and quick advance and quick retreat.

[0051] Optionally, refer to Figure 3 The toothed part 3 can be selectively inserted into the first surface 32 and the second surface 33 of the opening 223. The first surface 32 and the second surface 33 are connected and set at an angle. When the wrench is rotated clockwise, the locking member applies force to the first surface 32 so that the toothed part 3 extends into the opening 223; when the wrench is rotated counterclockwise, the locking member applies force to the second surface 33 so that the toothed part 3 retracts.

[0052] The tightening part 22 has a first abutting surface 225 facing the opening 223. When the locking member enters the opening 223 of the tightening part 22, the first abutting surface 225 and the first surface 32 clamp the locking member. Then, the handle 1 is turned clockwise, and the first abutting surface 225 and the first surface 32 clamp the locking member, causing the locking member to rotate and lock the locking member. However, when the turning space of the wrench is limited, when the locking member is turned, the handle 1 needs to be turned counterclockwise. At this time, the reaction force of the locking member on the second surface 33 of the tooth 3 causes the tooth 3 to press against the elastic member 4 and retract, so that the tightening part 22 has the functions of clamping the locking member and reversing free rotation reset at the same time.

[0053] Specifically, when the handle 1 is turned clockwise, the first contact surface and the first surface 32 clamp the locking member, causing the locking member to rotate and lock. The reaction force of the locking member on the first surface 32 of the tooth 3 and the elastic member 4 cause the tooth 3 to tend to extend into the opening 223. The cavity of the tightening part 22 has a first limiting part 224, which restricts the tooth 3 from continuing to move into the opening 223. When the handle 1 is turned counterclockwise, the reaction force of the locking member on the second surface 33 of the tooth 3 causes the tooth 3 to press against the elastic member 4 and retract, realizing the free-spinning reset of the wrench. When the handle 1 is rotated to a certain angle and the wrench needs to be turned clockwise again, the tooth 3 rebounds under the action of the elastic member 4 and continues to press against the locking member, thereby realizing the tightening or loosening of the locking member.

[0054] Optionally, refer to Figure 1 Along the first direction X, one end of the handle 1 is connected to the head 2, and the other end is provided with an anti-slip part 5. The anti-slip part 5 on the handle 1 is provided to increase friction and facilitate the operation of the operator.

[0055] When the wrench in this application enters the working space between the door and the body, the wrench first loosens the locking nut of the hinge connecting the door and the body, then adjusts the position of the door, and then uses the wrench to tighten the locking nut to the target torque. During the process of loosening and tightening the locking nut, the wrench can be moved back and forth. The wrench does not need to move in and out of the working position to realign with the locking nut, saving operation time.
