Abstract

The utility model relates to an improved structure of an extendible covered silencing buffering pad, particularly the silencing buffering pad made of flexible rubber. The silencing buffering pad has an excellent elastic buffering effect. Meanwhile, both sides of the silencing buffering pad are provided with two elastic ring bodies similar to a semicircular shape. A connecting block is also arranged between the two elastic ring bodies so as to be arranged in a clamping slot fixedly clamped on the periphery of an extendible cover. When the extendible cover is pulled apart or folded, the semicircular elastic ring bodies with the elastic buffering effect on both sides of the silencing buffering pad can be used for reducing and lowering the noise.

Description

A kind of noise reduction cushion pad of flexible covering improves structure

The noise reduction cushion pad that the utility model relates to a kind of flexible covering improves structure, is meant that especially the both sides of this noise reduction cushion pad respectively are provided with a semicircular elasticity circle body, and contiguous block is then established in the centre; When installing noise reduction cushion pad, contiguous block in the middle of utilizing directly is embedded and is fastened in flexible the covering in the default draw-in groove on every side, allow a plurality of flexible covering when drawing back or folding, can run into earlier can resiliently deformable semicircle elasticity circle body, be beneficial to reduce and reduce the generation of noise.

See also shown in Figure 1ly, be the schematic perspective view of flexible covering commonly used.The flexible covering 10 of tradition is applied in the comprehensive cutting processing machine of protection; lapping machine ... on linear slide rail on the machinery 20 or hard rail 30; roll driving screw ... Deng precision parts; main purpose is in order to prevent to cut water; dust; foreign material such as machined layer bits are invaded linear slide rail or hard rail 30; on the precision partss such as ball driving screw; avoid these precision partss by scratch; corrosion; even situations such as stuck take place; so as to protecting the precision of these mechanical 20 normal operations and processing; owing to flexible covering 10 must be moved along with the processing stroke; but cover 10 when drawing back or fold when flexible; can send the noise and the sound of disturbing the people because of collision each other; so must between flexible covering 10, install noise reduction cushion pad 40; wherein tradition noise reduction cushion pad 40 main utilizations commonly used itself are made the elastic reaction that is had by soft rubber; reduce and reduce flexible 10 noise and the sounds that when collision, sent that cover, see also shown in Figure 2: be the flexible combination generalized section that covers commonly used.But noise reduction cushion pad 40 that should be commonly used is in practical application, but still can't effectively reach the purpose of noise reduction, its reason mainly is: though noise reduction cushion pad 40 own materials commonly used have suitable soft spring-go effect, but the processing speed of machinery 20 comes more and more fast at present, flexible cover 10 open with folding also more and more soon and more and more frequent, if only depend on the elastic material of noise reduction cushion pad 40 to absorb crash shock, can not effectively reduce or reduce the noise and the sound that is produced, for this reason, the design people thinks the structure that thoroughly improve traditional noise reduction cushion pad 40.

The purpose of the utility model is, provides a kind of noise reduction cushion pad of flexible covering to improve structure, to reach the effect that abates the noise effectively.

The noise reduction of a kind of flexible covering provided by the utility model die head that contracts improves structure, on the surrounding edge position of a plurality of flexible coverings connecting part, cut open and establish several symmetrical draw-in grooves, to be embedded the noise reduction cushion pad of respective counts, it is characterized in that, the both sides of this noise reduction cushion pad respectively are provided with an elasticity circle body, the centre is then linked into an integrated entity two elasticity circle bodies by contiguous block, described contiguous block just can be embedded in the flexible draw-in groove that covers, and promptly the elastic ring body on noise reduction cushion pad both sides is positioned at the edge of the flexible inside and outside both sides that cover.Wherein, described elastic ring shape the best is semicircle.

Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing, so that the functional effect of further understanding structure content of the present utility model and reaching, wherein:

Fig. 1 is the schematic perspective view of flexible covering commonly used;

Fig. 2 A is the combination generalized section of flexible covering commonly used;

Fig. 2 B is the C-C sound view along Fig. 2 A;

Fig. 3 A is for having the flexible schematic perspective view that covers of the utility model noise reduction cushion pad;

Combination cross-sectional schematic when Fig. 4 A draws back for the flexible covering that has the utility model noise reduction cushion pad;

Fig. 4 B is the A-A sectional view along Fig. 4 A;

Combination cross-sectional schematic when Fig. 5 A folds for the flexible covering that has the utility model noise reduction cushion pad;

Fig. 5 B is the B-B sectional view along Fig. 5 A.

See also shown in Figure 3ly, be the schematic perspective view of the flexible covering that has the utility model noise reduction cushion pad.To be applied in condensation cutting processing machine, lapping machine ... Deng the linear slide rail of machinery 20 or the flexible covering 10 of hard rail 30 is example, wherein on the surrounding edge position of a plurality of flexible coverings 10 connecting parts, cut open and establish several symmetrical draw-in grooves 11, noise reduction cushion pad 50 as being embedded corresponding number sees also shown in Fig. 4 A, the 4B: be that flexible covering that has the utility model noise reduction cushion pad made up cross-sectional schematic when drawing back.Noise reduction cushion pad 50 of the present utility model mainly is respectively to be provided with a semicircular elasticity circle body 51 on both sides, the centre then is to utilize contiguous block 52 to link into an integrated entity, the width size of above-mentioned contiguous block 52 just can be embedded in the draw-in groove 11 of flexible covering 10, allow the semicircle elasticity circle body 51 on noise reduction cushion pad 50 both sides be positioned at flexible 10 inboard and the outer ledge place of covering, as keeping out and cushion and absorbing flexible 10 the crash shock power when drawing back or folding that cover.The shape of described elasticity circle body 51 can be any suitable geometrical shape, and its best is semicircle.

The noise reduction cushion pad that provides a kind of flexible covering by the utility model that above-mentioned each element combined improves structure, see also shown in Fig. 4 A, 4B, 5A, the 5B, for have the utility model noise reduction cushion pad flexible cover draw back, combination cross-sectional schematic when folding.On practical operation is used, when flexible covering 10 is drawn back or is folded, can run into the semicircle elasticity circle body 51 of noise reduction cushion pad 50 earlier, owing to semicircle elasticity circle body 51 can be extruded the effect with resiliently deformable, so can offset, cushion and sponge collision and vibration force, the noise reduction cushion pad 40 more commonly used than tradition more can reduce, reduce the noise and the sound of disturbing the people.

Comprehensively above-mentioned, the utility model provides a kind of can be applied in the flexible noise reduction cushion pad improvement structure that covers, this cushion pad through actual manufacture finish and the repetitiousness operational testing after, confirm really can reach the desired function and benefit of the utility model, simultaneously still do not have the novel product of information for present present technique field again, and met novelty, creativeness and the practicability of utility model patent.
