[0037] Example 1

[0038] like Figure 1 and Figure 2 As shown, this utility model provides a connector 100 for connecting different workpieces (not shown) with mounting holes. The connector 100 can connect two different workpieces together at once, or it can connect three different workpieces together at once, and the number of workpieces can be determined according to the actual use.

[0039] The connector 100 includes a main body 110, a cap 120, and a movable part 130. The main body 110 is a column extending along a first direction. The main body 110 can be a cylinder, a square column, a triangular column, an elliptical column, etc. Preferably, the main body 110 is a cylinder with a central axis X, and the first direction can be understood as the axial direction of the main body 110.

[0040] like Figure 3 As shown, the main body 110 has a first end 111 and a second end 112 in a first direction. The cap 120 is fixed to the first end 111 to form an integral part with the main body 110. The cap 120 and the main body 110 can be fixed by welding, gluing, integral molding or other methods.

[0041] Further, the first elastic member 160 is sleeved on the main body 110 and located on the outer periphery of the main body 110, wherein one end of the first elastic member 160 is fixed on the cap 120, and the other end of the first elastic member 160 is a free end. The first elastic member 160 provides an elastic force in the first direction, which acts on the workpieces to tightly abut the adjacent workpieces in the first direction.

[0042] At least part of the cap 120 is located outside the circumferential sidewall of the main body 110 to form a stepped limiting end, which is used to limit the limit position of the main body 110 when moving in the first direction 111 to the second direction 112. It is worth noting that the "circumferential", "axial", "radial" appearing in the specification are the "circumferential", "axial", "radial" of the main body 110 without special instructions.

[0043] The shape of the cap 120 is not limited and can be a circular block, a polygonal block, an elliptical block, etc. Preferably, the cap 120 is a circular block and is coaxially distributed with the main body 110, and the radial dimension of the cap 120 is greater than that of the main body 110. At this time, the projection of the cap 120 along the axial direction partially overlaps with the projection of the main body 110 along the axial direction, that is, the cap 120 has a projection area outside the projection of the main body 110. Of course, the shape of the cap 120 includes but is not limited to the above types, and the cap 120 can also be a block provided at the edge of the first end 111, at this time, the projection of the cap 120 along the axial direction has no overlapping area with the projection of the main body 110 along the axial direction.

[0044] The movable part 130 is movably arranged on the main body 110, wherein the movable part 130 is located at the second end 112 or near the second end 112. That is, the movable part 130 and the cap 120 are respectively located at the opposite ends of the main body 110.

When the movable part 130 has multiple, the multiple movable parts 130 are equally spaced along the circumferential direction of the main body 110. Preferably, the second end 112 is symmetrically provided with a pair of movable parts 130, and the two movable parts 130 are spaced apart by 180°, which can optimize the stress condition of the movable part 130 and prolong the service life of the connecting piece 100 to a certain extent.

[0046] The circumferential sidewall of the main body 110 is provided with a receiving groove 140 matched with the movable part 130. The movable part 130 has a first state of being accommodated in the receiving groove 140 and a second state of being at least partially extended out of the receiving groove 140 and protruding on the circumferential sidewall of the main body 110.

[0047] The active part 130 can be switched between the first state and the second state under the action of an external force. The above-mentioned "external force" includes an installation external force for driving the active part 130 to switch from the second state to the first state, and a reset external force for driving the active part 130 to switch from the first state to the second state.

[0048] The installation external force is an external force applied to the active part 130 by the installation hole. During installation, the active part 130 needs to pass from one side of the installation hole to the other side, that is, the active part 130 needs to pass through the installation hole together with the main body part 110.

[0049] As shown in Figure 1 The active part 130 has a bearing surface 131 for the installation external force to act on. The bearing surface 131 is an outer wall surface of the active part 130, and is arranged at an acute angle with the central axis X of the main body part 110. In the direction from the second end 112 to the first end 111, the distance between the bearing surface 131 and the central axis X gradually increases.

[0050] During the passing process, the hole wall of the installation hole always abuts against the bearing surface 131 of the active part 130, and the active part 130 is forced to move towards the central axis X under the constraint of the installation hole, and is switched from the second state to the first state. In the above process, the accommodation groove 140 plays a role of avoiding, so that the active part 130 smoothly passes through the installation hole.

[0051] After the active part 130 passes through the installation hole, the active part 130 needs to be switched from the first state to the second state. During the switching process from the first state to the second state, the operator can manually rotate the active part 130 to achieve it, or can realize the automatic switching of the active part 130 through the second elastic member 150. Hereinafter, the automatic switching of the active part 130 between the first state and the second state by means of the second elastic member 150 will be described as an example.

The second elastic member 150 is used to provide an elastic force perpendicular to the first direction, so as to automatically switch the active part 130 from the first state to the second state. The second elastic member 150 can be a compression spring, a torsion spring, a rubber spring tube, etc., and can also be other shapes of elastic bodies.

[0053] The shape of the second elastic member 150 is related to the connection mode of the active part 130. In an embodiment, as shown in Figure 1 and Figure 2As shown, one end of the movable part 130 is pivotally connected to the second end 112 through a pivot shaft 170 fixed in the accommodating groove 140, and the pivot shaft 170 is perpendicular to the central axis X. At this time, the movable part 130 is in the form of a strip-shaped plate body, which can be a straight strip or a wavy strip. Figure 4 As shown, the second elastic member 150 is in the form of a "V" shape, including a first elastic arm 151 and a second elastic arm 152. One end of the first elastic arm 151 is fixed to the groove wall of the accommodating groove 140, the other end of the first elastic arm 151 is fixedly connected to one end of the second elastic arm 152, and the other end of the second elastic arm 152 abuts against the movable part 130. Preferably, the second elastic member 150 is formed by bending a metal sheet, and the included angle between the first elastic arm 151 and the second elastic arm 152 is obtuse.
