Abstract
The invention relates to a weighing tool, in particular to a portable spring scale. The portable spring scale comprises a shell with a scale, a lifting ring and a pothook and is characterized in that a mainshaft is arranged in the middle of the shell, the front end of the mainshaft is provided with an indicator, springs and chutes which are parallel are respectively arranged at two sides in the shell, a support plate is movably connected between the two chutes, the support plate is fixedly connected with the springs at two sides, the middle part of the upper end of the support plate is connected with a flexible spring at the rear end of the mainshaft through a belt, and the pothook is fixedly connected to the middle part of the lower end of the support plate and extends out of the shell. Therefore, the invention has the beneficial effects of simple structure, convenience and practicability; the weighing errors are greatly reduced by the adoption of the belt and the flexible spring instead of the traditional gear drive; meanwhile, the problem that the spring scale is not capable of being used due to falloff of a gear is solved.
Description
(1) technical field
The present invention relates to a kind of weighing apparatus, particularly a kind of portable spring scale.
(2) background technology
Traditional in the market portable spring scale is used gear drive more, and then drives pointer and rotate, and will cause the error of scale bigger like this, and gear comes off easily, and spring is also loosening easily.
(3) summary of the invention
The present invention provides a kind of simple in structure, convenient and practical portable spring scale in order to remedy the deficiencies in the prior art.
The present invention is achieved through the following technical solutions:
A kind of portable spring scale, comprise the housing, drop handle and the hook that have scale, its special character is: described housing middle part is provided with main shaft, front-end of spindle is provided with pointer, both sides are arranged with parallel spring and chute respectively in the housing, are connected with back up pad between two chutes, and back up pad and both sides spring are affixed, the back up pad upper center is connected with the soft spring of rear-end of spindle by belt, and hook is fixed in middle part, back up pad lower end and projects outward from the housing.
After hanging up weight on the hook, hook pulling back up pad moves downward, and it is downward that back up pad drives belt, and belt is given the acting force transmission soft spring again and then driven pointer and rotates, and by the direct transmission of belt and soft spring, has reduced the error of weighing greatly.
Therefore, the invention has the beneficial effects as follows: simple in structure, convenient and practical, replace traditional gear drive with belt and soft spring, reduced the error of weighing greatly, solved the problem that gear comes off and causes spring balance to use simultaneously.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present invention.
Among the figure, 1 housing, 2 drop handles, 3 hooks, 4 chutes, 5 springs, 6 pointers, 7 back up pads, 8 belts, 9 main shafts, 10 soft springs.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises housing 1, the drop handle 2 that has scale and links up with 3, housing 1 middle part is provided with main shaft 9, main shaft 9 front ends are provided with pointer 6, both sides are arranged with parallel spring 5 and chute 4 respectively in the housing 1, be connected with back up pad 7 between two chutes 4, back up pad 7 is affixed with both sides spring 5, and back up pad 7 upper center are connected with the soft spring 10 of main shaft 9 rear ends by belt 8, and hook 3 is fixed in middle part, back up pad 7 lower ends and stretches out in outside the housing 1.
Adopt portable spring scale of the present invention, after hook hung up weight on 3, hook 3 pulling back up pads 7 moved downward, and it is downward that back up pad 7 drives belts 8, and belt 8 is given the acting force transmission soft spring 10 again and then driven pointer 6 and rotates, and can weigh up weight of heavy.Therefore, the invention has the beneficial effects as follows: simple in structure, convenient and practical, replace traditional gear drive with belt and soft spring, reduced the error of weighing greatly, solved the problem that gear comes off and causes spring balance to use simultaneously.
