Abstract

The utility model discloses a brush wire lock button which is a lock button tablet with a U-shaped lock button groove at the lower end in the middle. The lock button tablet is an inverted triangular which has been cut the apex angle, thus with the top wide and bottom narrow. The apex angle (3) of the triangle is 6 to 10 degree. The brush wire lock button can tightly fasten the brush wire in the holes, thus making the brush wire not easy to fall. The utility model has the advantages of simple structure , convenient manufacture and low cost, which is suitable for fastening the brush wire of any stamping brush wire.

Description

Brush bristle lock catch

Technical field

The utility model relates to a kind of Brush bristle lock catch, specifically relates to Brush bristle lock catch del, that have chucking brush silk function that a kind of quilt wide at the top and narrow at the bottom is clipped drift angle.

Background technology

In the field of industrial brush, often relate to the punching press of brush silk is planted in the hole of brush body, to block and be fixed in the hole in order brush silk, domestic and international manufacturer all adopts the 0.8-1mm steel wire as Brush bristle lock catch.The brush rotation produces centrifugal force during work, because steel wire is circular, outer rim is smooth, and does not have the active force of chucking between the hole wall of brush body hole, and the brush silk is subjected to action of centrifugal force to be easy to come off from hole, has seriously influenced the service life of brush.For overcoming above-mentioned shortcoming, the special the utility model that proposes.

Summary of the invention

The purpose of this utility model is to provide a kind of silk of will brushing to be stuck in tightly in the hole, makes brush silk difficult drop-off, is applicable to the Brush bristle lock catch of the brush of various punching press plantation brush silks.

Technical scheme provided by the utility model is: Brush bristle lock catch comprises the grip tab of the U-shape lock catching groove that has middle lower ending opening, and grip tab is the del that quilt wide at the top and narrow at the bottom is clipped drift angle, and grip tab drift angle (3) is 6 °-10 °.

Optimal technical scheme provided by the utility model is: Brush bristle lock catch is shorter in length than brush body hole degree of depth 2-3mm, grip tab upper end shoulder width is greater than hole diameter 0.4-0.6mm, the lower end width is less than hole diameter 0.3-0.4mm, and U-shape lock catching groove width is 2-3mm.

Brush bristle lock catch of the present utility model is shorter in length than brush body hole degree of depth 2-3mm, grip tab upper end shoulder width is greater than hole diameter 0.4-0.6mm, the lower end width is less than hole diameter 0.3-0.4mm, the size of U-shape lock catching groove decides what according to the brush silk, width is generally 2-3mm, block brush silk with the U-shape lock catching groove, the narrow end of grip tab is downward, and punching press is planted in the hole of brush body into.Because grip tab is wide at the top and narrow at the bottom, on the one hand, when the brush body hole was planted in the grip tab punching press, its lower end made the grip tab band the brush silk and is easy in the punching press plantation tunnel inlet less than the diameter of hole; On the other hand, when the brush silk is subjected to centrifugal action, because grip tab upper end shoulder width is greater than the hole diameter, imbed in the hole hole wall tightly on two summits of grip tab shoulder, generation overcomes the resistance of centrifugal force, makes the grip tab difficult drop-off, thereby reaches the purpose of locking brush silk.

The brush wire material comprises: metal raw silk rings, wavy metal silk, nylon raw silk rings, nylon corrugation, vegetable silk.

The brush body material comprises: nylon, plastics, hard wood.

The pulling force contrast that comes off of brush silk is as follows:

The snap close type	Domestic steel wire snap close	External steel wire snap close	The utility model snap close
The snap close type	Domestic steel wire snap close	External steel wire snap close	The utility model snap close	Pulling force (N)	50-70	150-200	400-500

The utility model has the advantages that:

1, this Brush bristle lock catch will be brushed silk and be stuck in tightly in the hole, make a brush silk difficult drop-off, be applicable to the brush silk locking of the brush of various punching presses plantation brush silks, improve the service property (quality) and the service life of punching press plantation brush silk brush.

2, this Brush bristle lock catch is simple in structure, and is easily manufactured, with low cost, can be widely used in the brush of various punching press plantation brush silks.
