Abstract

The utility model relates to an improved arrester for a band tape. The utility model mainly comprises a bottom cover, a stopping button, a band tape wheel body, an outer cover, etc. The function of braking can be obtained by a contact plane of the stopping button, which is tightly contacted with an annular contact plane arranged at one side of the band tape wheel body. The retraction speed of a band tape belt is decelerated, or the rotation of the band tape wheel body is fixed.

Description

The tape measure stop device

The utility model relates to a kind of improved tape measure stop device, a kind of modifying device of blocking buffering braking effect when increasing tape measure and reclaiming particularly is provided, to avoid tape measure excessive, make tape measure injure hand, thereby improve the security and the serviceable life of tape measure because of reclaiming rotating speed.

The use-pattern of conventional tape measure is that the user carries out surveying work with the stretched suitable length of tape measure, unclasps the blocking button of tape measure after measurement finishes, and makes band tpae sheet break away from the blocking effect of blocking button lower edge.Because of establishing a flexible reed (effect of similar clockwork spring) in the tape measure, have the function of powerful automatic recovery tape measure, and the tape measure stretching is long more, recovery speed is fast more, and this tape measure causes the quite shortcoming of inconvenience if make the just easy hand that hurts with sheet metal.And traditional tape measure is to push downwards with the backstop button, to support to arrive in band tpae sheet, slowing down its recovery speed or blocking stops, owing to be to be fastened with blocking button lower end and band tpae sheet, so it is unclear often to cause scale on the tape measure face to wear and tear, furthermore also imperfection of backstop effect.For making tape measure practicality more convenient to use, the utility model designer accumulates professional for many years manufacturing experience, studies, develops, and can bring into play better practical value for making the utility model, experience test of many times, improvement during this time, finished a kind of improved tape measure stop device.

Fundamental purpose of the present utility model is to provide a kind of improved tape measure stop device, in order to increase the blocking effect, reduces the speed that tape measure reclaims, and improves the security of gripping tape measure and the serviceable life of tape measure.

For achieving the above object, the utility model provides a kind of improved tape measure stop device, mainly comprises members such as bottom, backstop button, tape measure wheel body and enclosing cover.

By describing embodiment of the present utility model in detail below in conjunction with accompanying drawing, can be more specifically, be well understood to structural attitude of the present utility model and advantage.

Fig. 1 is the D structure synoptic diagram of tape measure stop device of the present utility model.

Fig. 2 is that the solid of tape measure stop device of the present utility model is decomposed organigram.

Fig. 3 is the user mode synoptic diagram of the backstop button of tape measure stop device of the present utility model.

At first, as shown in Figure 1 and Figure 2, the tape measure wheel body 50 of the utility model tape measure 10 inside, spiral helicine flexible shell fragment 52 of concentric circles of central authorities' coiling, foreign volume is around a tape strip 51, and flexible shell fragment 52 central parts of this tape measure wheel body 50 are set in the central shaft 21 of bottom 20; And tape strip 51 front ends place a buffering block 60, and holding is in bottom 20 and enclosing cover 30 bottom

front.Place screw

31,32,33 respectively with 3 screws 70, these enclosing cover 30 spiral shells are solid at the central shaft 21 of bottom 20 and fixedly on the

projection

22,23, be combined into one.

Wherein, this bottom 20 is established a circular slotted eye 24 in end section leading edge, and this slotted eye 24 places a backstop button 40, and this backstop button 40 protrudes out bottom 20, and and the slotted eye 24 of bottom 20 between fit have suitable tightness; And the and arranged on left and right sides of this tape measure wheel body 50 is respectively established a ring-type surface of contact 53.

As shown in Figure 1 to Figure 3, improved tape measure stop device of the present utility model, the tape strip 51 of this tape measure wheel body 50 is pulled outwardly out use (shown in " a " state among Fig. 3), because the flexible shell fragment 52 of tape measure wheel body 50 inside has the function of powerful automatic recovery tape strip 51, when tape strip 51 inwardly reclaims, can be affixed by the ring-type surface of contact 53 of tape measure wheel body 50 1 sides by means of the surface of contact 41 of backstop button 40, reach the effect of braking brake, slow down the recovery speed of tape strip 51 or the fixedly rotation of tape measure wheel body 50.

In sum, the utility model has improved the shortcoming of traditional product, on using, is the initiative in the like product really, and can brings into play bigger practical effect that disclosed structure can reach predetermined purpose really.

Claims

1. improved tape measure stop device comprising main members such as bottom, backstop button, tape measure wheel body and enclosing covers, is characterized in that:
