Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 10, the locking and positioning handle of the present embodiment includes:

the positioning device comprises a positioning unit 1, wherein the positioning unit 1 comprises a first groove 11 recessed towards the inside of the positioning unit and first abutting parts 12 positioned at two sides of the first groove 11. The first recess 11 may allow the pin 3 to extend into it, thereby providing space for the pin 3 to move. The first abutting portion 12 can abut the positioning unit 1 and the positioning seat 2, so as to provide a supporting position for changing a relative position relationship between the positioning portion 14 and the positioning seat 2. In addition, the first abutting portions 12 can limit the pin shaft 3 between the two first abutting portions 12, so that the pin shaft 3 is prevented from being separated from the first groove 11. The first abutting portion 12 may have an arc-shaped surface 13 at an edge thereof, the first abutting portion 12 may have a positioning portion 14, the positioning portion 14 may include a first end and a second end, and a distance between the first end and the arc-shaped surface 13 may be greater than a distance between the second end and the arc-shaped surface 13. The arc-shaped surface 13 enables the position where the arc-shaped surface 13 abuts against the positioning portion 14 to be changed by rotating the positioning unit 1, and then the pivoting position of the pin shaft 3 and the positioning unit 1 is changed, so that the pivoting position can be changed between the first end and the second end.

One end of the positioning seat 2 close to the positioning unit 1 may have a second groove 21 recessed inward, and the second groove 21 may be configured to accommodate the first abutting portion 12, so as to achieve a limiting effect on the first abutting portion 12. The second groove 21 may include a second abutting portion 22 located at a bottom end thereof and a side wall 211 abutting against the first abutting portion 12, and the side wall 211 may gradually extend outward from the second abutting portion 22 to an end of the positioning seat 2 close to the positioning unit 1, so that when the first abutting portion 12 on the positioning unit 1 is placed in the second groove 21, the positioning unit 1 may avoid a situation of being separated from the positioning seat 2 by a restoring force of the spring and a supporting force of the second groove 21.

The pin shaft 3 can penetrate through the positioning seat 2, and the elastic part 4 can be sleeved on the pin shaft 3. In the present embodiment, the elastic portion 4 is a compression spring. Of course, in other alternative embodiments, the actual structure of the elastic part 4 may be adjusted according to actual needs. One end of the elastic part 4 can abut against the pin shaft 3, and the other end of the elastic part 4 can abut against one side, away from the positioning unit 1, of the second abutting part 22, so that the elastic part 4 can change the relative position between the pin shaft 3 and the positioning seat 2 when different deformations occur, and further change the distance between one end, away from the positioning unit 1, of the pin shaft 3 and the positioning seat 2. One end of the pin shaft 3 can extend into the first groove 11 and be pivotally connected to the positioning unit 1, so that the positioning unit 1 can rotate relative to the positioning seat 2 in the process of rotating the positioning unit 1.

In an alternative embodiment, as shown in fig. 1 to 4, the positioning seat 2 is fixedly connected to a first plate, the positioning unit 1 is rotated to pivot the pin shaft 3 and the positioning unit 1 to the first end, and finally the pin shaft 3 is changed from a state of extending into a positioning hole in a second plate to a state of extending out of the positioning hole, so as to achieve the first working state. In this working state, the side wall 211 has at least two supporting positions with the positioning unit 1, so that the positioning unit 1 can be limited in the second side wall 211 by the side wall 211, and in this state, the first abutting portion 12 can be separated from the second abutting portion 22.

In another alternative embodiment, as shown in fig. 1, 2, 5, and 6, the positioning seat 2 is fixedly connected to the first plate, the positioning unit 1 is rotated to pivot the pin 3 and the positioning unit 1 to the second end, and finally the pin 3 gradually changes from a position outside the positioning hole on the second plate to a position extending into the positioning hole, so as to achieve the second working state. In this working state, the side wall 211 at least has a supporting position with the positioning unit 1, and the first abutting portion 12 needs to abut against the second abutting portion 22, so that the positioning unit 1 is limited in the second side wall 211 by the side wall 211 and the second abutting portion 22.

Borrow by above-mentioned structure, through changing the pin joint position at first end or second end for at the in-process of rotating positioning unit 1, the distance between the edge of location portion 14 and positioning seat 2 can supply through the constant head tank, thereby can avoid positioning unit 1 relative positioning seat 2 to take place the pivoted in-process the condition that the distance between edge of positioning unit 1 and the positioning seat 2 takes place great change, thereby saved the space, can adapt to and use in the less environment in space.

Specifically, the positioning portion 14 may be a through groove, and the positioning portion 14 may extend in a linear direction, so that a distance between the first end and the second end is shorter. The positioning portion 14 may be unitary in shape.
