Description

Single reforcing plate for improved brake handle

The utility model relates to the single reinforcing chip of a kind of improved plastic cement brake handgrip, belongs to the technical field of the handgrip that brakes.

General brake handgrip 10(commonly used is referring to accompanying drawing 1), contain and be shoulder 13 between grip part 11 and the connecting portion 12, be provided with a buckle groove 14 that is connected with straight trough portion 15 and translot portion 16 at shoulder 13 places, connect portion's 19 buckles pivot joint for brake bands 18 and button portion, and be provided with connecting bore 17 between the latter end of connecting portion 12, be used for being connected usefulness because of reservation articulates with handgrip.Because plastic cement handgrip 10 is to make with plastic material merely, its intensity is limited, so when reality is used, application force because of snapping brake bands 18, fall near straight trough portion 15 shoulders 13 of buckle groove 14, be easy to make near straight trough portion 15 shoulders 13 to deform, can't reach hundred-percent correct braking effect; Even can burst apart suddenly at the shoulder 13 at the epimere position of straight trough portion 15 and translot portion 16, make the snapping portion 19 of the bands 18 that brakes lose foundation, and lose braking action fully, to the bad consequence of traveling security generation, influence very huge.

Plastic cement brake handgrip 10A in second figure, though it can improve the intensity of shoulder, mainly be to be coated with a reinforcing chip 20 in plastic material (with dashed lines is partly represented among the figure) inside, this reinforcing chip 20 also contains grip part 21, connecting portion 22 shoulders 23 embeded slots 24, connecting bore 25 grades are corresponding with brake handgrip 10A region of interest, and are combined in brake crank 10A inside (Fig. 3).

In Fig. 3, the shoulder 23 of reinforcing chip 20 is to lower recess, and buckle groove 24 has one and is the opening 26 that expands outwardly shape, 14 translot portions 16 match with brake handgrip 10A buckle groove, thereby weakened the intensity of shoulder 23, so when button draws brake bands 18, the opening 26 that can make shoulder 23 buckle grooves 24 is dilatating and deformable gradually, make between the buckle groove of brake bands and brake handgrip, clearance space enlarges when brake, also just can't finish meeting pulling force is transmitted on the brake, causes brake correctly not brake,, be difficult to service life simultaneously improve significantly to still having misgivings in secure side.

By Fig. 4, plastic cement brake handgrip 10B, its reinforcing chip 30 still contains grip part 21, connecting portion 32 shoulders 33, embeded slot 34 connecting bores 35 grades are corresponding with the region of interest of brake handgrip 10B, and are combined in brake handgrip 10B inside (referring to Fig. 5).

By Fig. 5, the shoulder of this reinforcing chip 30 raises up, and on buckle groove 34, be provided with a straight opening 36, make shoulder 33 just in time be positioned at brake handgrip 10B translot portion 16 tops, straight opening 36 is corresponding with 15 ones of the straight troughs of buckle groove 14 simultaneously, opening 36 its shapes of this reinforcing chip 30 are also slightly variant with foregoing reinforcing chip 30, aspect practical application, because when straight opening 36 both sides shoulders 33 draw the brake bands at button, can deform and buckle groove 34 is enlarged, so gap increasing between snapping portion that brake the time still can make the brake bands and buckle groove, pulling force is communicated on the brake by the brake bands, therefore can not correctly brake, all exist shortcoming in its safety and service life, can not improve.

The purpose of this utility model is to provide a kind of improved plastic cement brake handgrip single reinforcing chip, it can overcome above-mentioned shortcoming, it mainly is the shoulder that between reinforcing chip grip part and connecting portion, is provided with to lower recess, and one sealing buckle hole is set at suitable position, make reinforcing chip cooperate plastic material to coat and form when braking handgrip, the buckle hole just in time communicates with the buckle groove, and be positioned at below the buckle groove crosspiece portion, this structure can guarantee under any circumstance, shoulder and buckle groove can not be out of shape, make brake correctly reliable, and show to land and prolong brake handgrip service life.

The purpose of this utility model is to realize like this;

The single reinforcing chip of improved plastic cement brake handgrip, this reinforcing chip 40 has long grip part 41 of extending, and have one than short connecting portion 42, the adjacent position of grip part 41 and connecting portion 42 suitably depression becomes shoulder 43, the buckle hole 44 that on shoulder 43, has closure, and connecting portion 42 latter ends have connecting bore 45, and this reinforcing chip 40 can coat plastic material and constitute the brake handgrip that an inside has reinforcing chip 40.Reinforcing chip 40 usefulness metallic material punching presses are made, and the buckle hole 44 of shoulder 43 is connected with the buckle groove 50 of brake handgrip 50, and shoulder 43 is positioned at translot portion 52 belows of buckle groove 51.

Now in conjunction with the accompanying drawings the structure of improved plastic cement brake handgrip with single reinforcing chip is described in detail.

By Fig. 6, reinforcing chip 40 usefulness metallic material punching presses are made has long grip part 41 of extending, and have than short connecting portion 42, the adjacent position of grip part 41 and connecting portion 42 suitably depression becomes shoulder 43, on shoulder 43, be provided with the buckle hole 44 of closure, and connecting portion 42 latter ends has connecting bore 45.

This reinforcing chip 40 can cooperate that mould is fixing to be coated with plastic material, constitutes an inside thus and has the plastic cement brake handgrip 50(of reinforcing chip 40 referring to Fig. 7).

By Fig. 7, the buckle hole 44 of shoulder 43 connects with the buckle groove 51 of plastic cement brake handgrip 50, and shoulder 43 is positioned at the translot portion 52 belows (referring to Fig. 8) of buckle groove 51.

In Fig. 8, buckle hole 44 communicates with buckle groove 51, shoulder 43 is positioned at translot portion 52 belows of buckle groove 51, make the buckle hole 44 of shoulder 43 that opening can be set, also can successfully be fastened on the snapping portion 19 of brake bands 18 in buckle groove 53 and the buckle hole 44, and brake bands 18 embeds in the translot portion 52.

Can see by Fig. 7, because reinforcing chip 40 is closeds in the buckle hole 44 of shoulder 43, the integraty that can keep shoulder 43, and the intensity of shoulder 43 is not damaged, even in the effect magnitude range that the brake bands can bear, can not make

shoulder

43 and 44 distortion of buckle hole yet, so when the snapping portion of brake bands embeds, can obtain comprehensive bundle closes, make snapping portion and buckle hole 44 keep certain clearance, can be delivered to the pulling force that handgrip applied that brakes fully on the brake, therefore can obtain not only correct reliable but also safe braking effect.

Because the shoulder 43 of reinforcing chip 40 is subjected to application force and indeformable with buckle hole 44, shoulder and the buckle hole that relatively just can slow down the plastic cement brake take place to wear and tear or damage, thereby can prolong the service life of plastic cement brake effectively in addition.

Compared with prior art, improved plastic cement brake handgrip has following advantages with single reinforcing chip

1, the grip part of reinforcing chip becomes shoulder with the adjacent position of connecting portion to lower recess, and the buckle groove that shoulder has buckle hole and surface to coat plastic material formation is connected, and can not be out of shape under the effect of bands pulling force, guarantees that brake is correct reliable, and safer.

2, the not easy to wear or damage in shoulder and buckle hole, the service life of relatively prolongation brake handgrip.
