Abstract

The utility model relates to a beating hammer for a timing device, particularly the major part of an ageing timing device or toy timing device for timing in the scientific research laboratory, the hospital therapeutic department and the office. The beating hammer for a timing device is composed of a hammer plate provided with a tail pin, a connecting column and a clamping port, wherein, the tail pin, the connecting column, the clamping port and the hammer plate are the integral beating hammer formed by casting once. Because the beating hammer for a timing device is formed by casting the same metal material, the sound of the vibrating bell of the beating hammer for a timing device is brilliant, euphonious and clear. Simultaneously, the beating hammer for a timing device has the advantages of simple manufacturing process, easy processing, assured and stable quality, high productivity and low cost.

Description

Timer is played hammer

The utility model relates to the critical part in a kind of timer, particularly is used for the effective timer that timing uses or the timer of toy timer and plays hammer in scientific experiment chamber and hospital's psyciotherapy room and office.

The employed hammer of beating in the existing effective timer is the part of being made by three kinds of different materials, connects into again wholely to constitute, and its manufacturing process complexity, precision is low, processing bothers, take a lot of work, time-consuming, the low and price height of product percent of pass.

The purpose of this utility model is to provide a kind of timer to play hammer, and it is simple in structure, precision is high, has not only enhanced product performance, but also has boosted productivity and production cost is low.

The utility model is achieved in that timer plays hammer and be made up of the hammer plate that has end pin, joint pin, bayonet socket, and described end pin, joint pin, bayonet socket and hammer plate are to play hammer through the integral body of a casting forming.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Hammer plate (1), (6), the pincer of (7) two ends for closing up to the centre, the centre is irregular strip.

In the middle of the joint pin (5) is cylindrical, and two ends are spindle nose (2), and two ends are conical transition with the centre.

Hammer plate shape can be according to the casing that is mated (15) shape, and decision is different shapes.

On one end face of hammer plate (1), (6), (7) end pin (4) and a spindle nose (2) are arranged, joint pin (5) with a spindle nose (2) is arranged on the end face in addition, on the other hammer plate (1) of joint pin (5), (6), (7), have one to concave, and an edge is the bayonet socket (3) of profile of tooth.

Playing hammer (8) is made with casting forming of allumen by hammer plate (1), the joint pin (5) of tape spool head (2), bayonet socket (3), end pin (4).

To play hammer (8) and utilize the spindle nose (2) on it to be separately fixed between upper and lower two base plates of prior art timer, and cooperate with escapement (9) on the timer.The gear (17) that is connected with quarter-bell clockwork spring (14) and fuses on the axle (16) with end pin sheet (18), and gear (17) meshes with transferring wheel (19), as shown in Figure 9.

During use, elder generation's clockwise direction is rotated and is transferred wheel (19) to tighten clockwork spring (10), quarter-bell clockwork spring (14), timer is started working, clockwork spring (10) drives each gear train and rotates, and make ratchet (11), ratchet (12) drives escapement (13), the motion that hairspring does not stop, transfer wheel (19) counterclockwise to rotate simultaneously, the gear (17) of magnetic tape trailer pin sheet (18) is rotated, forward the indentation, there of former reference position to when end pin sheet (18), at this moment the end pin of beating on the hammer (8) (4) enters breach, and quarter-bell clockwork spring (14) just unclamps and gives off energy, driven gear and escapement (9), tooth on the escapement (9) is pushed the bayonet socket of beating on the hammer (8) (3) open, make an end of hammer plate (1) hit casing (15) inwall and send ring tone, arrive, all unclamp up to quarter-bell clockwork spring (14) to the user prompt time.The same with the prior art course of work.

The utility model is compared with prior art: because the existing hammer of beating is casting forming of usefulness same metal material Make, so productivity ratio raising, quality assurance, stable, easily processing, technology is simple, production cost is low, And that quarter-bell sends is clear, melodious, clear. And the former hammer of beating is each part in addition of being made by different materials, Assembling connects into integral body again, so complex process, defect rate height, cost height.
