During self-locking, the locking plate 5 moves relative to the rotating shaft assembly along the radial direction, so that the positioning block 51 is clamped into the positioning groove, and the axial rotation of the rotating shaft assembly is restrained. The elastic piece enables the stopping block 6 to be clamped into the stopping hole 101, so that the locking plate 5 is positioned, and the self-locking of the locking plate 5 is realized. During unlocking, acting force is applied to the lock plate 5, the acting force overcomes the elastic force of the elastic piece to enable the stop block 6 to leave the stop hole 101, and the positioning block 51 is far away from the positioning groove to unlock the rotating shaft assembly under the action of the acting force. The radial direction and the axial direction are determined according to the rotating shaft of the rotating shaft assembly.
In the prior art, the locking plate 5 is generally self-locked by the elasticity of the spring, and the direction of the elasticity enables the positioning block 51 to press towards the positioning groove, but the self-locking effect is poor due to the instable rigidity of the spring and the installation clearance. The motion of the locking plate 5 needs to overcome the frictional resistance, and in the prior art, the locking plate 5 is generally in surface contact with the base plate 1, so that the base plate 1 applies a large resistance to the locking plate 5, and the motion of the locking plate 5 is not smooth.
According to the rotating shaft stop lock provided by the utility model, the stop block 6 and the stop hole 101 are arranged, and the stop block 6 and the stop hole 101 are matched and positioned to lock the lock plate 5, so that the lock plate 5 is stable in self-locking and not easy to loosen, and the spacing columns 2 are arranged between the lock plate 5 and the base plate 1, and the spacing columns 2 separate the base plate 1 and the lock plate 5, so that the friction resistance generated by surface contact between the base plate 1 and the lock plate 5 is avoided, the friction resistance generated when the lock plate 5 moves can be reduced, and the lock plate 5 moves more smoothly.
The locking plate 5 may be provided with one or more stop holes 101, and when a plurality of stop holes 101 are provided, the locking plate 5 can be switched among a plurality of different self-locking states by changing the stop hole 101 into which the stop block 6 is inserted.
According to some embodiments of the present invention, the substrate 1 is formed with a mounting hole 102 therethrough, and the stop block 6 is disposed in the mounting hole 102. The stop block 6 can move along the mounting hole 102 under the action of the elastic piece, and self-locking is realized when the stop block 6 is exposed out of the mounting hole 102 and clamped into the stop hole 101. In some embodiments, the elastic member includes an elastic pressing plate 7, the elastic pressing plate 7 is disposed on a side of the base plate 1 away from the locking plate 5, one end of the elastic pressing plate 7 is fixed on the base plate 1, and the other end of the elastic pressing plate 7 covers the mounting hole 102.

When the stop block 6 corresponds to the stop hole 101 of the lock plate 5, the elastic pressure plate 7 enables the stop block 6 to be clamped into the stop hole 101 to realize self-locking. When the self-locking is released, the locking plate 5 is pushed to move, the locking plate 5 exerts force on the stop block 6, and the stop block 6 forces the elastic pressing plate 7 to bend so as to allow the stop block 6 to slide out of the stop hole 101.
In some embodiments, the diameter of stop block 6 is greater than the thickness of substrate 1 to ensure that stop block 6 is exposed through mounting hole 102 and snaps into stop hole 101, for example, the thickness of substrate 1 is equal to two-thirds the diameter of stop block 6. Of course, the diameter of the stop block 6 may be smaller than or equal to the thickness of the substrate 1, and in this case, a protrusion may be formed on the elastic pressing plate 7, the diameter of the protrusion is smaller than the diameter of the mounting hole 102, and the protrusion can be snapped into the mounting hole 102 to expose the stop block 6 out of the mounting hole 102.
It will be appreciated that the stop block 6 may take a variety of shapes other than a spherical shape, with the shape of the stop hole 101 being adapted to the shape of the stop block 6. The normal direction of the contact point of the stop block 6 with the sidewall of the stop hole 101 should be not parallel to the axial direction and the radial direction, so that the elastic force of the elastic member can be converted into a force in the radial direction applied to the lock plate 5 to block the movement of the lock plate 5 at the time of self-locking, and the force applied to the lock plate 5 can be converted into a force in the movement direction of the stop block 6 applied to the stop block 6 to move the stop block 6 against the elastic force of the elastic member at the time of unlocking. For example, the shape of the stop block 6 may be a bulb cylinder shape, a truncated cylinder shape, a conical shape, or the like. The stop hole 101 may be a blind hole or a through hole.

In some embodiments, the base plate 1 is provided with at least two guide grooves 103, the axes of the guide grooves 103 are parallel, and the locking plate 5 can move along the axial direction of the guide grooves 103. The guide posts 12 limit the radial movement of the lock plate 5.

For example, as shown in the embodiment of fig. 3, the lock plate 5 is provided with four guide posts 12 in an array of 2 × 2, the guide posts 12 are inserted into the guide grooves 103, the spacer posts 2 are sleeved on the guide posts 12 and fixed by nuts 201 and spacers 202, the diameter of the spacer posts 2 is smaller than that of the guide grooves 103, the length of the spacer posts 2 is larger than the thickness of the base plate 1, and the spacer posts 2 are spaced between the lock plate 5 and the base plate 1 so as to reduce the friction resistance when the lock plate 5 moves.
It will be appreciated that the spacer 2 may take other shapes and that the spacer 2 may be located at other positions between the lock plate 5 and the base plate 1. For example, the spacers 2 may be balls, rollers, or spacers, and when the spacers 2 are spacers, the spacers may be fixed on the substrate 1 or the lock plate 5, and the size of the spacers is much smaller than that of the substrate 1, and the spacers can reduce the size of the friction surface of the lock plate 5 during movement, thereby reducing the friction resistance.
