Abstract

The utility model relates to an improved balance-bell double-duty device with both bicycle bell function and spring balance function. Under a spring of the device, a rotation screw that resets pointers by hand is provided. One hook to weigh heavy goods and one to weigh light goods are provided directly on a bell handle. All of transmissions are completed with an arc handle, an arc teeth bar that is connected with the arc handle and a gear that joggles with the arc teeth bar. The design eliminates the defects that when light goods are weighed, the balance bell is unable to be perpendicular to the handlebar and pointers can not be reset in the proprietary technology, Balance and Bell Double-Duty Device (patent number: 99209221.x). The utility model is simpler in structure, and is made more easily, operates more conveniently and is more delicate in appearance.

Description

Improved type Two-purpose installed on bicycle with bell and balance function device

Technical field

The utility model relates to a kind of improved type Two-purpose installed on bicycle with bell and balance function device that has bicycle and spring balance function concurrently.

Background technology

Chinese patent 99209221.x 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, we find that there is following drawback in this device: 1, this device adopts the engagement of several gears, tooth bar to realize title, bell function, and structure is loaded down with trivial details, makes to be difficult for; 2. this device only utilizes the elastic force of spring to realize that pointer resets, and the repeated use backpointer is difficult to get back to original position; 3. traditionally, people should be not less than 5 kilograms to the requirement of weighing of small spring scale, according to present technique, reach big like this weighing, will increase the pulling force of spring, still, the result who does like this will make people use very big strength when ringing a bell, even also can miss fire, can't realize two kinds of functions of bicycle bell and spring balance, so this technology can only the lighter article of weighing; 4, claim that hook position under the bicycle bell is nearer,, claim hook and handlebar to produce the position and conflict, weighing can't be carried out,, had a strong impact on outward appearance U.S. so the bicycle bell inclination can only be installed on the handlebar in the present technique if bicycle bell is stood on handlebar.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned existing in prior technology defective, provides a kind of simple in structure, simple for production, easy to use, perfect in shape and function, the improved type 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 improved type Two-purpose installed on bicycle with bell and balance function device, comprise bell lid, bell handle, dial plate, cover the chassis that fixes and be located at set collar on the outer rim of chassis by bell lid frame and bell, it is characterized in that: the one side on described chassis is provided with arc-shaped rack, this arc-shaped rack is meshed with gear, and the one end is with the arc handle captive joint; One end of described arc handle is fixed on the jointed shaft, and the other end is applied on the revolving bar, is hung with spring on the described revolving bar, the lower end of this spring be located at the exterior rotary screw in chassis and be connected; Said gear is fixed on the center shaft, and described center shaft runs through simultaneously and is fixed on chassis and the dial plate, and also is fixed with pointer on it, and dial plate is marked with scale graduation; Be provided with the bell pendulum on the another side on described chassis, the bell pendulum is fixed on the center shaft; Described bell is fixing by jointed shaft and chassis, this bell on two title hooks are installed;

Described dial plate top is equipped with transparency cover.

Improved type Two-purpose installed on bicycle with bell and balance function device of the present utility model is provided with one and is used for the rotary screw of realizing that manually pointer resets in the spring lower end; Directly on the bell handle, the title hook of two weighings than heavy articles and lighter items is set; Utilize an arc handle to reach the arc-shaped rack of captive joint with it, reach with the arc gear wheel gears in mesh and finish all transmissions, above-mentioned design has overcome patented technology " Two-purpose installed on bicycle with bell and balance function device ", and (patent No.: the weighing article are light 99209221.x), claim that bell can't stand on handlebar, defectives such as pointer can't reset, its structure is more simple, makes more easy, use also more conveniently, outward appearance is also more exquisite.

The specific embodiment

Improved type Two-purpose installed on bicycle with bell and balance function device of the present utility model comprise bell lid 1, bell 4, dial plate 20, chassis 2 etc., above-mentioned chassis 2 is covered 1 by bell lid frame 22 and bell and is fixed, and is provided with set collar 17 on the outer rim on chassis 2.

Be provided with arc-shaped rack 8 on the one side on chassis 2, this arc-shaped rack 8 is meshed with gear 9, and the one end is with arc handle 10 captive joints.On chassis 2, be fixed with jointed shaft 7, one end of arc handle 10 is fixed on this jointed shaft 7, the other end is applied on the revolving bar 14, be hung with spring 6 on the described revolving bar 14, the lower end of this spring 6 be located at chassis 2 exterior rotary screws 16 and be connected, be used for the manual regulation pointer 19 times zero, pointer 19 is fixed on the center shaft 5, described center shaft 5 runs through simultaneously and is fixed on chassis 1 and the dial plate 20, and dial plate 20 is marked with scale graduation 18, and transparency cover 23 is installed above dial plate 20; Said gear 9 also is fixed on the center shaft 5.2 another side is provided with bell pendulum 3 on the chassis, and bell pendulum 3 is fixed on the center shaft 5.Above-mentioned bell fixes 4 by jointed shaft 7 and chassis 2, this bell stretches out 4 cracks 21 between bell lid 1 and chassis 2 outside the bell, diverse location place is separately installed with by jointed shaft 11 and jointed shaft 12 and claims hook 13 and claim hook 15 on it, when the weighing lighter items, use and claim hook 15, weighing is during than heavy articles, with claiming hook 13.

When improved type Two-purpose installed on bicycle with bell and balance function device of the present utility model uses as small bell, press bell 4 arc handles 10 are driven arc-shaped rack 8, gear 9 and 3 rotations of bell pendulum, thereby beat bell lid 1; When using, article are hung over claim hook 13 or claim on the hook 15 that under the effect of gravity, bell drives arc handles 10, arc-shaped rack 8, gear 9 and pointer 19 rotations to 4, i.e. weight as can be known from the scale graduation 18 as spring balance.
