Abstract

The utility model relates to an automatic fixed tape which is composed of a casing body, a rotary wheel, a press-key, a buckle body, etc., wherein, the buckle body and the rotary wheel which rotate can form the effect of a ratchet wheel. When a tape sheet is pulled out, the rotary wheel rotates and can be automatically positioned in a microspur mode, so the tape sheet is prevented from rolling up fast to hurt a user. The press-key can press the vertical sheet of the buckle body to cause the vertical sheet to drive the transverse sheet to rise, so the effect of the ratchet wheel is eliminated, and the tape sheet can put back swimmingly. The utility model has the advantages of reasonable structure and safety, and is suitable for the existing various steel tapes.

Description

Automatic fixed tape

The utility model relates to a kind of locating device, and particularly a kind of tape measure stretches automatic positioning equipment.

Existing steel tape does not generally all have locating device, measures the quick rollback of back band tpae sheet meeting that finishes, and injures the user easily.Even there are some steel tapes that locating device is arranged, also all be to realize by the mode of pushing down band tpae sheet, this kind locator meams is reliable inadequately, occurs skidding sometimes.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of band tpae sheet that makes arbitrarily to locate automatically, and tape measure rational in infrastructure, reliable in action stretches automatic positioning equipment.

The purpose of this utility model can reach by following measure: the utility model comprises housing, runner, button, button, it is characterized in that: housing is provided with newel, four corners are respectively equipped with the screw projection, one side of housing is offered a key hole and a button projection, side-lower is provided with baffle plate in the key hole, runner is hollow form, the two-wheeled sheet is holded up in its both sides, outer ring, the wheel sheet is provided with equidistant monocline teeth groove continuously, the runner hollow bulb sets up a wind spring sheet separately and is incorporated on the newel of housing, button is provided with a pivot hole, and can be placed on the button projection, and the snap portion of button below can be its button stop, button is one to be the elastic body of L type shape, has a vertical plate, and heading joint is connected in a horizontal plate, two corner inboards are established a mesopore and can be placed on the screw projection, the horizontal plate below connects a transverse sheet that extends to both sides outward by mesopore, the length of transverse sheet just is slightly larger than the width of runner, wherein the end of vertical plate is to one pushed section of outer process, and push away in the button splenium, the horizontal plate end supports portion together to outer process, and is butted on the housing inboard, edge forms a button portion before the transverse sheet, can be buckled in the teeth groove of runner.

Fig. 1 is a three-dimensional exploded view of the present utility model;

Fig. 2 is in structural representation under the positioning states for the utility model;

Fig. 3 is in structural representation under the release conditions for the utility model.

The utility model makes a detailed description below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1～Fig. 3, the utility model is by housing 1, the runner 2, button 3, button 4 etc. of rollback are formed automatically.Housing 1 is provided with on a newel 11, four corners and is respectively equipped with screw projection 14, and a side of housing is offered a key hole and a button projection 13, and a flat opening 12 is established in the below, hole, and side-lower is established a baffle plate 15 in the key hole.Runner 2 is hollow form, and two-wheeled sheet 23 is holded up in its both sides, outer ring, can supply coiling band tpae sheet 21 therebetween, and wheel sheet 23 is provided with equidistant monocline teeth groove continuously, and runner 2 hollow spaces can be installed with a wind spring sheet 22, and are incorporated on the newel 11 of housing 1.Button 3 is provided with a pivot hole 32, and its inboard, top is a straight splenium 31, and its bottom side, below is the snap portion 33 of bent angle, and pivot hole 32 can be placed on the button projection 13, and snap portion 33 can baffle plate 15 be its button stop.Button 4 is one to be the elastic body of L type shape, has a vertical plate 41, and the right angle is a horizontal plate 43 in succession, two corner inboards are established a mesopore 42 and can be placed on the screw projection 14, horizontal plate 43 belows connect a transverse sheet 44 that extends to both sides outward by mesopore, the length of transverse sheet 44 just is slightly larger than the width of runner 2, wherein the end of vertical plate 41 is outwards given prominence to one pushed section 45, and push away in button splenium 31, horizontal plate 43 ends support portion 46 together to outer process, and being butted on housing 1 inboard, edge forms a button portion 47 before the transverse sheet 44, can be buckled on the teeth groove of runner 2.

Button 4 forms ratchet effect with runner 2, can make band tpae sheet 21 pull out, runner 2 rotates and can make microspur and locate automatically, prevent that band tpae sheet 21 quick rollbacks from injuring the user, button 3 then can be pushed the vertical plate 41 of button 4, make it to drive transverse sheet 44 and rise, thereby eliminate ratchet effect, make band tpae sheet 21 regain smoothly.

The utility model has following advantage compared to existing technology: the random microspur of band tpae sheet is located automatically, prevent that its quick rollback from injuring the user; And rational in infrastructure, safe and reliable, the cost of required increase is lower, applicable to existing all types of steel tape.
