Abstract
The utility model discloses an elastic brake device for a caster, which comprises a top plate and a supporting plate, wherein rollers that are distributed in an annular manner are arranged on a riveting contact surface of the top plate and the supporting plate; a sleeve is also arranged on one side of the supporting plate; a brake sliding pin is arranged in the sleeve; a radial through hole is formed in one end of the brake sliding pin; a partition board close to the end socket is arranged at the other end of the brake sliding pin; the brake sliding pin close to the partition board extends out of the sleeve; a compression spring is also arranged among the other side of the partition board, the inner wall of the sleeve and the side wall of the brake sliding pin; a radial U-shaped opening is formed at one end of the sleeve; and one section of a pull ring penetrates through the through hole and is positioned in the U-shaped opening. The elastic brake device achieves novel braking method, effectively avoids the problem that a traditional braking device cannot be locked, achieves simple structure, and is beneficial to manufacturing.
Description
Technical field
The utility model relates to a kind of castor brake gear, is specifically related to a kind of elasticity brake gear for castor.
Background technology
Universal caster wheel can be level 360 degree rotations in dynamic load or static load, so extensively apply to so extensively apply on supermarket shopping car, logistics hand barrow, the rolling cart, but in existing life and commercial production, need castor to turn to flexibly simultaneously, also to guarantee the stability when static load, castor brake gear of the prior art, most gears that adopt mesh braking, and this brake mode can cause and can't lock because gear can not accurately mesh.
Summary of the invention
In order to solve the problem that prior art exists, the utility model provides a kind of elasticity brake gear for castor.
The utility model is realized by the following technical solutions: comprise top board, support, the contact surface of top board and support riveted joint is provided with the roller of annular spread, rack side wall is provided with 4 grooves of well-distributed, support one side also is provided with sleeve, the sleeve side surface is captiveed joint with top board, be provided with the brake sliding pin in the sleeve, brake sliding pin one end is provided with radial direction through hole, the other end of brake sliding pin is provided with dividing plate near the position of termination, the brake sliding pin of dividing plate one side stretches out sleeve, and stretches in the groove; Also be provided with the compression spring between dividing plate opposite side, sleeve lining and the brake sliding pin sidewall, sleeve one end is provided with U-shaped opening radially, and draw ring passes described radial direction through hole and is positioned at the U-shaped open interior for one section.
The beneficial effects of the utility model are: the utility model is by the cooperate braking of the groove on the support with the brake sliding pin, and braking is stable, and simple in structure because of it, the elasticity brake gear is detachable, reduces production costs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is assembling scheme drawing of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is explained in detail.
As shown in Figure 2, comprise top board 1, support 2, the contact surface of top board 1 and support 2 riveted joints is provided with the roller 3 of annular spread, and support 2 sidewalls are provided with 4 grooves 21 of well-distributed, and support 2 one sides also are provided with sleeve 4, and sleeve 4 side surfaces are captiveed joint with top board 1.
As shown in Figure 1, be provided with brake sliding pin 5 in the sleeve 4, brake sliding pin 5 one ends are provided with radial direction through hole 6, and the other end of brake sliding pin 5 is provided with dividing plate 7 near the position of termination, and the brake sliding pin 5 of dividing plate 7 one sides stretches out sleeve 4, and stretches in the groove 21; Also be provided with compression spring 8 between dividing plate 7 opposite sides, sleeve 4 inwalls and brake sliding pin 5 sidewalls, sleeve 4 one ends are provided with U-shaped opening 10 radially, and draw ring passes described radial direction through hole 6 and is positioned at U-shaped opening 10 inside for 9 one sections.
When described draw ring 9 was subjected to pulling force, described brake sliding pin 5 produced radial displacements, and the part that brake sliding pin 5 stretches out sleeve 4 withdraws from groove 21, was retracted in the sleeve 4, and compression spring 8 shrinks, and recovered relative rotation, the releasing brake between top board 1 and the support 2.
When stopping described draw ring 9 application of forces, described brake sliding pin 5 produces reciprocal radial displacement under the effect of compression spring 8 restoring forces, brake sliding pin 5 stretches out outside the sleeve 4, enter in the groove 21, described top board 1 can not relatively rotate with support 2, thereby finishes brake.
