Abstract

The utility model relates to a high-weighing-accuracy scale and bell dual-purpose device. By arranging two sets of power mechanisms on the device, particularly arranging a separate rope wheel power transmission mechanism on a weighing mechanism, the defects of mechanical losses caused by the transmission of a hinge shaft, a rack and a gear during weighing and weighing inaccuracy caused by changes of the stress of the hinge shaft and a tension spring when a vehicle is inclined can be avoided. Thereby, the goals of high weighing accuracy and simple and practical structure can be realized.

Description

Weighing is the Two-purpose installed on bicycle with bell and balance function device accurately

Technical field

The utility model relates to a kind of having concurrently and weighs and the weighing of the double function of bicycle bell Two-purpose installed on bicycle with bell and balance function device accurately.

Background technology

Chinese patent " improved type Two-purpose installed on bicycle with bell and balance function device " (patent No. 200610093992.2) provides a kind of Two-purpose installed on bicycle with bell and balance function device, and this device is installed on the bicycle, both can do bicycle bell and use, and can do portable title usefulness again, and is convenient and practical.But, in actual use, find that there is following drawback in this device: 1, this device when weighing since the transmission of power will through drive tooth bar behind the hinge axis again, gear rotates, thereby consumes power greatly, make weigh very inaccurate; 2, bicycle bell must stand on handlebar, this is because when weighing, bicycle bell tilts to make the gravity that acts on the jointed shaft to strengthen, the pulling force that acts on extension spring reduces, jointed shaft and extension spring produce stressed variation, cause bicycle bell to have inclination to make slightly to weigh inaccurate, yet in fact bicycle will often stay in different occasions, it also some inclinations can occur sometimes in installation and use, be difficult to guarantee that bicycle bell stands on handlebar, so will make that the scale of pointed is serious is not inconsistent with actual weight, and these problems very difficult or can't resolve on this device at all, thereby greatly reduce the practicality of this device.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned existing in prior technology defective, provides a kind of weighing accurate, simple in structure, simple for production, easy to use, perfect in shape and function, the Two-purpose installed on bicycle with bell and balance function device of exquisite appearance.

As follows for realizing the technical scheme that the purpose of this utility model adopted:

A kind of weighing is the Two-purpose installed on bicycle with bell and balance function device accurately, comprise base, the bell handle, set collar on annular dial plate and the base outer rim, it is characterized in that: described bell is the front that is fixed on base by jointed shaft, the one end is by outside the crack protuberate basic unit on the base side, and be fixed with axle in its end, little rope sheave is installed on the axle successively and claims hook, the other end of the rope of installing on the little rope sheave is fixed on the rope sheave, rope sheave is fixed in the back side of base by center shaft, going barrel is coaxial with rope sheave, edge at this going barrel is fixed with clockwork spring, and the other end of clockwork spring is fixed on the center shaft; The other end of bell handle is captiveed joint with arc-shaped rack, and this arc-shaped rack is meshed with gear drive, gear drive and coaxial being fixed on the center shaft of bell pendulum; Above-mentioned annular dial plate is around the outer rim that is installed in going barrel;

On the above-mentioned axle ratchet is installed also;

The front of described base indicates the finger heavy label.

Weighing of the present utility model is the Two-purpose installed on bicycle with bell and balance function device accurately, by two cover actuating units are set, particularly the independent rope sheave Power train of one cover is set to Weighing mechanism, the inaccurate drawback of weighing that makes the stressed variation of jointed shaft that the utility model do not have to bring behind mechanical wear that the transmission of jointed shaft, rack and pinion causes and the inclination of vehicle, extension spring and cause when weighing, thereby realized that weighing is accurate, simplified practical purpose.

The specific embodiment

Weighing of the present utility model is the Two-purpose installed on bicycle with bell and balance function device accurately, comprises base 1, the bell set collar 22 8, on annular dial plate 21 and base 1 outer rim.

Above-mentioned bell is fixed on the front of base 1 to 8 by jointed shaft 9, the one end is by outside crack 10 protuberate basic units on base 1 side, and be fixed with axle 11 in its end, sidepiece is fixed with rope hook 13, ratchet 28, ratchet 25, marline wheel 26 are installed on the axle 11 successively and claim hook 12, claim that 12 on hook can be hung on by the rotation of ratchet on the rope hook 13; On marline wheel 26, be installed with rope 17, these 17 other ends of restricting extend in the base and are fixed on the rope sheave 15 along

crack

14,15 of described rope sheaves are the back side that is fixed on base 1 by center shaft 18, going barrel 16 is fixed on the center shaft 18 with rope sheave 15 homonymies, be fixed with clockwork spring 20 at the edge of this going barrel 16, the other end of clockwork spring 20 is fixed on the center shaft 18; Outer rim at going barrel 16 is surrounded with annular dial plate 21, and annular dial plate 21 is marked with scale graduation 24, indicates in the front of base 1 to refer to heavy label 23.

Above-mentioned bell 8 the other end then with annular rack 27, this annular rack 27 is driven by gear drive and rotates, be specially: annular rack 27 is meshed with driven gear 2, driven gear 2 and big gear wheel 4 are coaxial and be fixed on the front of base 1 by anchor shaft 3, big gear wheel 4 is meshed with driving gear 7, and it is 6 coaxial and be fixed on the front of base 1 by center shaft 18 that driving gear 7 and bell are put.
