Abstract
The utility model provides a button spring scale which comprises a shell, a fixed shaft fixed in the shell, a scale tape winding around the fixed shaft, a scale hook fixed at an end of the scale tape, and a scale mouth allowing in and out of the scale tape. An upper part of the scale mouth is rotationally hinged with a pressing block; a connecting rod is hinged inside the shell; a head of the connecting rod is provided with a push rod; the push rod extends to a rear end of the pressing block and an end face of the push rod is abutted with a rear end face of the pressing block; a spring piece is arranged between a front end face of the pressing block and an inner wall of the shell; a tail end of the connecting rod is fixed with a button; and the button extends to an outside of the shell. The button spring scale of the utility model is simple in structure, convenient and fast in braking, and good in braking performance.
Description
Technical field
The utility model relates to a kind of tape measure, particularly a kind of button shell fragment scale.
Background technology
Tape measure is survey instrument commonly used in people's daily life.Tape measure after measurement completes, the automatic contraction of inner spring, the chi band and then shrinks under the effect of spring force, automatically roll.Brake system braking inconvenience and the weak effect of traditional tape measure.
The utility model content
The technical matters that (one) will solve
The technical problems to be solved in the utility model is to provide a kind of brake convenient and effective button shell fragment scale.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of button shell fragment scale, comprise housing 1, be fixedly mounted on the stationary shaft 2 in described housing 1, be wrapped in the chi band on described stationary shaft 2, be fixed on the chi hook of described chi strap end portion, and the chi mouth of the described chi band turnover of appearance, rotate the top of described chi mouth is hinged with briquetting 5, in described housing 1, be hinged with connecting rod 4, the head of described connecting rod 4 is provided with push rod 7, the end face that described push rod 7 extends to the rear end of described briquetting 5 and described push rod 7 props up the rear end end face of described briquetting 5, between the front end end face of described briquetting 5 and the inwall of described housing 1, be provided with spring leaf 6, the afterbody of described connecting rod 4 is fixed with button 3, described button 3 extends to described housing 1 outside.
Further, the sidewall of described housing 1 offers the rope hole 8 for lanyard.
Further, the bottom surface of described briquetting 5 is arc surface.
(3) beneficial effect
The utility model button shell fragment scale, adopt the form promotion briquetting of button rotate and make it unclamp the chi band, makes the smooth and easy turnover of chi band energy; During release button, briquetting compresses the chi band under the effect of spring leaf, make its location; Adopt spring leaf, good springiness, and can not vacillate now to the left, now to the right and cause the slippage of briquetting left and right; The utility model button shell fragment scale is simple in structure, brakes convenient and swift and good braking effect.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model button shell fragment scale.
Embodiment
Consult Fig. 1, the utility model provides a kind of button shell fragment scale, comprise housing 1, be fixedly mounted on the stationary shaft 2 in housing 1, be wrapped in the chi band on stationary shaft 2, be fixed on the chi hook of chi strap end portion, and the chi mouth of appearance chi band turnover, that above the chi mouth, rotates is hinged with briquetting 5, in housing 1, be hinged with connecting rod 4, the head of connecting rod 4 is provided with push rod 7, the end face that push rod 7 extends to the rear end of briquetting 5 and this push rod 7 props up the rear end end face of briquetting 5, between the front end end face of briquetting 5 and the inwall of housing 1, be provided with spring leaf 6, spring leaf can be snakelike or spirality, good stability, afterbody at connecting rod 4 is fixed with button 3, this button 3 extends to housing 1 outside, in order to be convenient for carrying, offer the rope hole 8 for lanyard at the sidewall of housing 1, in order to improve braking effect, prevent from scratching the chi band, the bottom surface of briquetting 5 is arc surface.
The utility model button shell fragment scale, adopt the form promotion briquetting of button rotate and make it unclamp the chi band, makes the smooth and easy turnover of chi band energy; During release button, briquetting compresses the chi band under the effect of spring leaf, make its location; Adopt spring leaf, good springiness, and can not vacillate now to the left, now to the right and cause the slippage of briquetting left and right; The utility model button shell fragment scale is simple in structure, brakes convenient and swift and good braking effect.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
