Description

Technical Field

[0001] The utility model relates to the field of measurement auxiliary equipment, in particular to a self-locking flip caster. Background Art

[0002] After the workpiece is processed, it needs to be placed on the measuring bracket and sent to the measuring equipment for measurement together with the measuring bracket. During measurement, there are requirements for the working state of the measuring bracket, and the measuring bracket needs to be placed on the measuring plane. The bottom of the traditional measuring bracket is not equipped with casters, resulting in the need for the staff to carry the workpiece after it is placed on the measuring bracket, which is time-consuming and laborious. If the casters are installed, the bracket needs to be repeatedly removed and installed when it is placed on the measuring equipment, which is very troublesome. In order to solve the above problem, self-locking flip casters are required. Utility Model Content

[0029] like Figures 1 to 7 As shown:

[0030] The self-locking flip caster comprises a base plate 1, a flip plate 3, a caster assembly 4, a locking assembly and a limiting assembly.

[0031] The top of the base plate 1 is connected with a mounting plate 2, and the caster assembly 4 is connected to the bottom of the flip plate 3, and the caster assembly 4 is detachably connected to the flip plate 3. A hinge seat 14 is provided at the right end of the base plate 1, and the right end of the flip plate 3 is hinged on the hinge seat 14 through a pin 15. A limited slot 5 is provided on the base plate 1, and a clamping assembly adapted to the structure of the limited slot 5 is connected to the flip plate 3. The flip plate 3 has a supporting state and a flipping state. When the flip plate 3 is in the supporting state, the upper end surface of the flip plate 3 is attached to the lower end surface of the base plate 1, and the clamping part of the clamping assembly is clamped into the limited slot 5. The limiting assembly has an elastic telescopic part. When the flip plate 3 is in the flipping state, the elastic telescopic part of the limiting assembly is used to support the flip plate 3.

[0032] The locking assembly includes a support seat 7, a sliding block 9 and a spring 8. The outer end of the sliding block 9 is the locking part of the locking assembly. A guide groove 6 from left to right is opened at the left end of the base plate 1. The sliding block 9 is slidably installed in the guide groove 6. The support seat 7 is fixedly connected to the outer end of the guide groove 6. The spring 8 is located between the support seat 7 and the sliding block 9. Under the action of the elastic member, the sliding block 9 is locked into the limiting groove.

[0033] Specifically, the limit assembly includes a limit bracket 10 and an elastic limit shaft 11. The mounting plate 2 and the limit bracket 10 are connected to the bottom of the measuring bracket (not shown in the figure). The elastic limit shaft 11 is connected to the limit bracket 10, and the elastic head of the elastic limit shaft 11 is the elastic telescopic part of the limit assembly.

[0034] A stopper 12 is provided on the side of the flip plate 3 close to the limit assembly, and when the flip plate 3 is in the flip state, the elastic telescopic part of the limit assembly is used to support the stopper 12. Specifically, the stopper 12 has an inclined surface 13 facing the caster assembly 4, and when the flip plate 3 rotates from the supporting state to the flip state, the inclined surface 13 of the stopper 12 pushes the elastic telescopic part of the limit assembly until the flip plate 3 is in the flip state.
