[0010] Furthermore, the diameter of the movable groove is greater than the diameter of the threaded rod.

[0011] Furthermore, a plurality of ribs are arranged at equal angles on the inner wall of the cavity of the stud, and a groove is provided on the fixing ring at the position corresponding to the ribs, the ribs extend from top to bottom along the axial direction of the stud and form a rotation groove with the bottom surface of the cavity of the stud, the diameter of the rotation groove is larger than the diameter of the fixing ring, and the fixing ring can move freely in the rotation groove along the X direction or the Y direction.

[0025] The following will be combined with 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 of 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. Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a tolerance adjuster capable of realizing three-way adjustment comprises a coaxially mounted fixing sleeve 1 and a stud 2, wherein the fixing sleeve 1 is sleeved on the outside of the stud 2, the fixing sleeve 1 and the stud 2 are threadedly connected, and a bolt 3 is movably connected inside the stud 2.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the inner wall of the fixing sleeve 1 and the outer wall of the stud 2 are respectively formed with an internal thread 11 and an external thread 21, and the pitch of the external thread 21 is greater than the pitch of the internal thread 11. Therefore, after the stud 2 is threadedly connected to the fixing sleeve 1, the stud 2 has a certain margin for upward or downward movement. In this embodiment, the stud 2 can move 3-7 mm along the Z direction relative to the fixing sleeve 1.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6As shown, in the present embodiment, a stop block 22 is provided on the top outer edge of the stud 2, and the stop block 22 extends horizontally to beyond the diameter length of the stud 2, while the fixing sleeve 1 is a hollow cylindrical structure with openings at both ends. The stud 2 is rotated to move upward or downward relative to the fixing sleeve 1. When the stop block 22 abuts against the fixing sleeve 1, the stud 2 in the fixing sleeve 1 can be limited and constrained, thereby effectively preventing the stud 2 from escaping from the fixing sleeve 1, and achieving a better actual use effect.

[0029] In this embodiment, the stop block 22 is made of elastic material, has a large friction force, a better restraining effect, and reduces damage to the fixing sleeve 1 itself.

[0030] like Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, a cavity for the movement of the bolt 3 is formed in the middle of the stud 2, the top of the stud 2 is open, and a movable groove 25 is formed at the bottom of the stud 2. The opening at the top of the stud 2 and the movable groove 25 are both connected to the cavity of the stud 2. The bolt 3 is composed of an upper bolt head 31, a middle fixing ring 32 and a lower threaded rod 33. The diameter of the fixing ring 32 is larger than the bolt head 31 and the threaded rod 33. The internal cavity space of the stud 2 is larger than the outer contour of the fixing ring 32. When the bolt 3 enters the cavity of the stud 2 from the opening at the top of the stud 2 from top to bottom, the threaded rod 33 is inserted into the movable groove 25. At this time, turning the bolt head 31 can drive the entire bolt 3 to rotate, thereby fixing the relevant parts.

[0031] In this solution, the diameter of the movable groove 25 is larger than the diameter of the threaded rod 33. When the threaded rod 33 is inserted into the movable groove 25, since the internal cavity space of the stud 2 is larger than the outer contour of the fixing ring 32, the bolt 3 can move along the X direction or Y direction relative to the bottom surface of the inner cavity of the stud 2.

[0032] This solution simplifies the relevant structure, and can achieve tolerance adjustment in the X, Y and Z directions by relying on the cooperation of the three components of the fixing sleeve 1, the stud 2 and the bolt 3, which can effectively improve efficiency and reduce costs in both production and use. Example

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, a tolerance adjuster capable of realizing three-way adjustment comprises a coaxially mounted fixing sleeve 1 and a stud 2, wherein the fixing sleeve 1 is sleeved on the outside of the stud 2, the fixing sleeve 1 and the stud 2 are threadedly connected, and a bolt 3 is movably connected inside the stud 2. Compared with the first embodiment, the difference of this embodiment is that: Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, the inner wall of the cavity of the stud 2 is provided with a plurality of ribs 23 at equal angles, and the fixing ring 32 is provided with a groove 34 at the position corresponding to the rib 23. The rib 23 extends from top to bottom along the axial direction of the stud 2, but the bottom end of the rib 23 is not connected to the bottom surface of the cavity of the stud 2. A rotation groove 24 is formed between the bottom end of the rib 23 and the bottom surface of the cavity of the stud 2. The height of the rotation groove 24 is greater than the thickness of the fixing ring 32, and the diameter of the rotation groove 24 is greater than the diameter of the fixing ring 32. Therefore, when the bolt 3 is inserted into the cavity of the stud 2, the fixing ring 32 is The groove 34 on the ring 32 is aligned with the rib 23, and the bolt 3 is slid downward until the bottom surface of the fixing ring 32 contacts the bottom surface of the inner cavity of the stud 2, and the threaded rod 33 is inserted into the movable groove 25. At this time, the fixing ring 32 is located in the rotating groove 24, and the fixing ring 32 can move freely in the rotating groove 24 along the X direction or the Y direction, which means that the bolt 3 as a whole can move along the X direction or the Y direction with respect to the bottom surface of the inner cavity of the stud 2. Such a structural design makes it difficult for the bolt 3 inserted into the stud 2 to be separated from the stud 2, thereby ensuring the reliability of the tolerance adjuster after installation.

[0034] In this embodiment, the top of the rib 23 is chamfered so that the two can be butted together faster and more conveniently when the fixing ring 32 moves downward.

[0035] In the description of this specification, the description with reference to the terms "one embodiment", "example", "specific example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0036] The above contents are merely examples and explanations of the present utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the present utility model.
