As shown in fig. 1, 4 and 6, some embodiments of the present utility model provide a tolerance adjuster, mainly for assembling and fixing components to be assembled, especially in the field of automobile parts.

The tolerance adjuster includes a locking member 100, a clamping member 200, a connecting structure 300, and a connecting member 400.

Specifically, the locking member 100 includes a connecting column 110 and a connecting block 120 disposed at one end of the connecting column 110, where a connection manner between the connecting block 120 and the connecting column 110 includes any one of threaded connection, adhesion, clamping connection or integral molding, and may be specifically set according to practical situations.

In this embodiment, in order to improve the overall strength of the locking member 100, the locking member 100 is formed by integrally molding the connection post 110 and the connection block 120, the connection block 120 is disposed at one end of the connection post 110 in the axial direction, and the axis of the connection block 120 coincides with the axis of the connection post 110.

Meanwhile, at least one first limiting portion 130 is disposed on a side of the connection block 120 facing the connection column 110, the first limiting portion 130 is adjacent to the connection column 110, and the number of the first limiting portions 130 may be one, two or more than two arbitrary values. It should be noted that, when the number of the first limiting portions 130 is plural, there is a space between two adjacent first limiting portions 130, and the plurality of first limiting portions 130 are all disposed around the circumference of the connecting post 110.

In this embodiment, the connecting column 110 is a hollow tubular structure, or the connecting column 110 is a hollow structure with one end open, which can be specifically set according to practical situations.

The side wall of the connecting post 110 is provided with a second limiting groove 111, preferably, the second limiting groove 111 is a bar-shaped groove, and the second limiting groove 111 is disposed along the first direction.

In addition, the clamping member 200 is provided with a first connecting hole 210, at least one second limiting portion 220 is disposed at an edge of the clamping member 200, specifically, at least one second limiting portion 220 is disposed at a side of the clamping member 200 facing the connecting block 120, the second limiting portions 220 are adjacent to an edge of the first connecting hole 210, and the number of the second limiting portions 220 is equal to that of the first limiting portions 130, and one first limiting portion 130 corresponds to one second limiting portion 220, and when the locking member 100 rotates relative to the clamping member 200, the first limiting portion 130 can form a limiting effect on the second limiting portions 220.

Specifically, the fastening member 200 is sleeved on the connection post 110, and the fastening member 200 abuts against the connection block 120, it is understood that the fastening member 200 can move along the axial direction of the connection post 110.

Further, an elastic piece 230 is disposed at an end of the clamping piece 200 away from the connecting block 120, a first protrusion 231 is disposed on the elastic piece 230, and the first protrusion 231 can be clamped in the second limiting groove 111, so that when the first protrusion 231 is not clamped in the second limiting groove 111, the elastic piece 230 has an elastic force to enable the first protrusion 231 to have a pressing force on the outer wall of the connecting column 110, and when the connecting column 110 rotates relative to the clamping piece 200 until the first protrusion 231 corresponds to the second limiting groove 111, at this time, the first protrusion 231 is clamped in the second limiting groove 111 under the elastic force of the elastic piece 230 to form a limiting structure, and thus a limiting structure is formed between the clamping piece 200 and the connecting column 110 to improve the stability between the clamping piece 200 and the connecting column 110, that is, the stability between the clamping piece 200 and the connecting block 120 is improved.

In this embodiment, the connecting structure 300 includes a fastener 320, and the clamping member 200 is elastically connected to the fastener 320 along a first direction, it is understood that the clamping member 200 is disposed on one side of the fastener 320, and the clamping member 200 can move along the first direction relative to the fastener 320 under the action of elastic force. Further, since the clamping member 200 is sleeved on the connecting post 110, that is, when the clamping member 200 moves along the first direction relative to the connecting structure 300, a limiting effect can be formed on the clamping member 200 by the limiting post 354, so as to improve the stability of the clamping member 200 in the moving process of the first direction.

Further, one end of the connecting member 400 abuts against the first connecting plate 322 on the fastening member 320, and the other end of the connecting member 400 is threaded through the connecting structure 300 to be connected with the connecting post 110 in a threaded manner, so that the distance between the end of the locking member 100 away from the connecting member 400 and the connecting member 400 can be adjusted during the threaded connection between the connecting member 400 and the connecting post 110, that is, during the rotation of the connecting member 400 relative to the connecting post 110.

Specifically, in the process of rotating the locking member 100 relative to the locking member 200, when the first limiting portion 130 abuts against the second limiting portion 220, the area of the non-overlapping region between the connecting block 120 and the locking member 200 is S1 on the projection along the first direction, and when the first limiting portion 130 and the second limiting portion 220 have a gap, the area of the non-overlapping region between the connecting block 120 and the locking member 200 is S2 on the projection along the first direction, so that S1 > S2 is satisfied.

It should be noted that, when the locking member 100 rotates relative to the clamping member 200, the locking member and the clamping member 200 are mutually staggered, and when the first limiting portion 130 abuts against the second limiting portion 220, the area S1 of the non-overlapping area between the connecting block 120 and the clamping member 200 reaches the maximum, that is, at this time, the fixing of the tolerance regulator to the plate-like structure can reach the most stable state, that is, the limiting effect of the tolerance regulator on the plate-like structure is improved through the limiting effect between the first limiting portion 130 and the second limiting portion 220, so that the user can quickly fix the maximum fixing position of the tolerance regulator to the plate-like structure in the process of rotating the locking member 100 relative to the clamping member 200, thereby ensuring the accuracy and the limiting efficiency of the plate-like structure when the user uses the tolerance regulator, and avoiding the influence on the locking effect of the locking member 100 caused by the too small or too large rotating angle of the user in the use process.

Specifically, when the tolerance regulator provided by the utility model is used for fixing the plate-shaped structure, the connecting block 120 of the locking block passes through the hole in the plate-shaped structure, and one side, close to the plate-shaped structure, of the connecting structure 300 is abutted against the plate-shaped structure to form a limiting effect on the locking block, at this time, when the locking block is rotated, the clamping piece 200 is clamped in the hole of the plate-shaped structure, namely, the plate-shaped structure forms a limiting effect on the clamping piece 200, namely, when the locking piece 100 is rotated, the clamping piece 200 cannot rotate along with the locking block, namely, after the locking block rotates, the clamping piece 200 forms dislocation with the hole of the plate-shaped structure, and the locking piece 100 and the hole of the plate-shaped structure form dislocation through the dislocation, namely, the plate-shaped structure is fixed between the connecting structure 300 and the locking piece 100 through the connecting structure 300 and the locking piece 100, so that the stability of the plate-shaped structure on the tolerance regulator can be ensured.

It should be noted that, by rotating the locking block, the first limiting portion 130 is abutted against the second limiting portion 220, at this time, the area of the non-overlapping area S1 between the connecting block 120 and the clamping piece 200 is maximized, so that the tolerance regulator can be quickly and accurately enabled to reach an optimal fixed state, and the experience of the user is improved.

In addition, since the plate-like structures have a difference in thickness, the connection member 400 and the locking member 100 are relatively rotated by the rotation, so that the locking member 100 is moved in the first direction, and the connection structure 300 and the connection block 120 are respectively abutted against opposite sides of the plate-like structures, thereby achieving locking of the plate-like structures. In this process, when the connecting piece 400 is rotated, since the clamping piece 200 is elastically connected with the connecting structure 300, the tolerance regulator and the plate structure can be corrected and compensated in the first direction through the elastic force between the clamping piece 200 and the connecting structure 300, so that the error compensation of the thickness of the plate structure in the first direction is realized, and finally, the component to be assembled is locked and fixed, the automatic compensation of the component to be assembled is realized, and the assembly efficiency and reliability are improved.

The first direction in this embodiment refers to the axial direction of the connection post 110.

As shown in fig. 3, 7 and 8, in some embodiments of the present utility model, the first limiting portion 130 is a first limiting rib, the second limiting portion 220 is a first limiting groove, and an outer wall of the first limiting rib and an inner wall of the first limiting groove can be mutually attached.

Along the circumferential direction of the connecting post 110, the thickness of the first limiting portion 130 is gradually increased to form a slope-shaped structure, and the depth of the second limiting portion 220 is gradually increased, so that the locking member 100 can play a role of tolerance compensation in the first direction in the process of rotating relative to the clamping member 200 due to different thicknesses of two ends of the first limiting portion 130. It should be noted that, when the end of the first limiting portion 130 with the larger thickness rotates toward the end of the second limiting portion 220 with the smaller depth, at this time, the first limiting portion 130 has a pushing force on the clamping member 200, so that the clamping member 200 moves in a direction away from the connecting block 120, thereby achieving tolerance compensation.

Specifically, along the first direction, the thickness of one end of the first limiting portion 130 is equal to the depth of one end of the second limiting portion 220, and the thickness of the other end of the first limiting portion 130 is equal to the thickness of the other end of the second limiting portion 220, so that the locking area of the tolerance adjuster can be maximized in the process of rotating the tolerance adjuster relative to the clamping piece 200, thereby forming a limit between the clamping piece 200 and the locking piece 100, and thus, when the first limiting portion 130 and the second limiting portion 220 are mutually attached to each other in the process of rotating the locking piece 100 relative to the clamping piece 200, the accuracy and the rotation efficiency of the rotation angle of the locking piece 100 relative to the clamping piece 200 can be improved, the tolerance adjuster can form a stable locking state to the plate-shaped structure rapidly, and the locking area of the tolerance adjuster can be maximized, so that the locking quality of the tolerance adjuster is improved.

It should be noted that, in some embodiments of the present utility model, the number of the first limiting portion 130 and the number of the second limiting portion 220 may be any number of one, two or more, and may be specifically set according to practical situations.

The first limiting portion 130 and the second limiting portion 220 are described as two exemplary embodiments. The two first limiting portions 130 are respectively disposed on two opposite sides of the connecting post 110, a space is provided between the two first limiting portions 130, the two second limiting portions 220 are respectively disposed on two opposite sides of the clamping piece 200, a space is provided between the two second limiting portions 220, and one first limiting portion 130 corresponds to one second limiting portion 220. It should be noted that, when one of the first limiting portions 130 abuts against one of the second limiting portions 220, at the same time, the other one of the first limiting portions 130 abuts against the other one of the second limiting portions 220, so as to further improve stability and accuracy of the locking member 100 in the rotation process relative to the locking member 200, and thus the tolerance regulator can quickly and accurately reach an optimal locking state.

As shown in fig. 7 and 8, in some embodiments of the present utility model, the first limiting portion 130 is a convex shape, and the second limiting portion 220 is a concave shape. Along the circumferential direction of the connecting post 110, the thickness of the first limiting portion 130 is gradually reduced, and it should be noted that, the thickness of the first limiting portion 130 refers to a vertical distance from a side of the first limiting portion 130 away from the connecting block 120 to the connecting block 120. Along the circumferential direction of the connection post 110, the depth of the second limiting portion 220 is gradually reduced, and it should be noted that, the depth of the second limiting portion 220 refers to the difference between the distance from the side of the second limiting portion 220 facing the connection post 110 to the side of the clamping member 200 facing away from the connection block 120 and the thickness of the clamping member 200 along the axial direction of the clamping member 200.

In the process of rotating the connection block 120 along the second direction relative to the connection block 200, when the first limiting portion 130 is engaged with the second limiting portion 220, at this time, one side of the connection block 120 facing the connection block 200 and one side of the connection block 120 facing the connection block 200 are completely engaged, and the first limiting portion 130 abuts against the second limiting portion 220 to form a limiting structure, that is, at this time, the connection block 120 cannot be continuously rotated along the second direction, so that stability of a relative position and accuracy of a rotation angle between the connection block 120 and the connection block 200 are ensured. In addition, when the connection block 120 rotates along the third direction relative to the clip 200, the first limiting portion 130 is gradually away from the second limiting portion 220, and forms an extrusion effect on the second limiting portion 220 through the first limiting portion 130, and pushes the clip 200 to move away from the connection block 120.

The second direction and the third direction are opposite to each other. Specifically, when the second direction is clockwise, then the third direction is counterclockwise. When the second direction is counterclockwise, the third direction is clockwise, and can be specifically set according to practical situations.

Specifically, the central angle corresponding to the first limiting portion 130 is equal to the central angle corresponding to the second limiting portion 220, and the length of the first limiting portion 130 is equal to the length of the second limiting portion 220 along the circumferential direction of the connecting column 110, so that when the first limiting portion 130 and the second limiting portion 220 are mutually attached, the first limiting portion 130 and the second limiting portion 220 can be completely matched.

In the first direction, the state when the locking member 100 and the engaging member 200 are overlapped is defined as an initial state of the tolerance adjuster, that is, in the initial state, the connection block 120 of the tolerance adjuster can pass through the hole of the plate structure, and cannot form locking to the plate structure.

Specifically, in the present embodiment, the projections of the clamping member 200 and the locking member 100 are square along the first direction, so when the locking member 100 rotates 45 ° relative to the clamping member 200, the area of the non-overlapping area formed by the misalignment between the clamping member 200 and the locking member 100 is maximized, that is, the most stable locking state can be achieved by the tolerance adjuster.

That is, when the tolerance adjuster is in the initial state and the locking member 100 rotates 45 ° relative to the clamping member 200, at this time, the first limiting portion 130 abuts against the second limiting portion 220, so that the first limiting portion 130 and the second limiting portion 220 form a limiting effect on the locking member 100 during rotation, so as to improve accuracy and rotation efficiency of a rotation angle of the locking member 100 relative to the clamping member 200, thereby improving locking efficiency and locking quality of the tolerance adjuster.

As shown in fig. 4 to 6, in some embodiments of the present utility model, the side wall of the connection post 110 is provided with a second limit groove 111, preferably, the second limit groove 111 is a bar-shaped groove, and the second limit groove 111 is disposed along the first direction.

Meanwhile, a first protrusion 231 is provided at an inner wall of the first connection hole 210. Preferably, the first protrusion 231 is an elastic protrusion, so that the first protrusion 231 and the second limiting groove 111 not only can limit the locking block and the locking piece 200, but also can prevent the first protrusion 231 from affecting the locking block in the process of rotating relative to the locking piece 200, thereby ensuring the fluency of the locking piece 200 in the process of rotating relative to the locking block.

Along the first direction, when the first protrusion 231 is clamped in the second limiting groove 111, the clamping member 200 is overlapped with the locking member 100, so that the tolerance regulator can quickly recover the initial state in the rotating process, and the assembling accuracy of the tolerance regulator is improved, and meanwhile, the assembling efficiency and the production efficiency can be improved.

As shown in fig. 1, 2, 9 and 17, in some embodiments of the present utility model, the connection structure 300 includes a fixed snap ring 310, the fastening member 320, an elastic member 330, a limiting member 340, an adjusting member 350 and a base 360.

The adjusting member 350 defines a first channel 351, the clamping member 200 and the limiting member 340 are respectively disposed at two ends of the first channel 351, one end of the elastic member 330 abuts against the clamping member 200, and the other end of the elastic member 330 abuts against the adjusting member 350, and it should be noted that the clamping member 200 is slidably connected with the first channel 351, so that the clamping member 200 can slide along the first channel 351 under the action of the elastic force of the elastic member 330.
