Description

A kind of timer

Technical field

The utility model relates to a kind of timing device, relates in particular to a kind of timer.

Background technology

In people's routine work life, timer is used widely.The prior mechanical timer is arranged in the timer casing owing to quarter-bell, so the volume ratio of timer is bigger; If the cancellation quarter-bell will be very little with beating the sound that hammer directly beats shell and sent, under the prerequisite of its quality of assurance and quarter-bell sound, doing that the volume of timer can not be breakthrough is little.

Summary of the invention

Goal of the invention of the present utility model is to have overcome the deficiencies in the prior art, and a kind of timer is provided, and under the prerequisite that guarantees its quality and performance, the volume of timer can be done for a short time, and it is louder that the tinkle of bells during quarter-bell becomes.

The technical solution of the utility model is: a kind of timer, comprise the movement in shell and the shell, main shaft is fixedlyed connected with the movement cam, the movement cam is provided with groove, contact is connected with movable contact spring with groove coupling and the push rod that is slidingly connected, and described shell is provided with a hole (7), beats the hammer body of hammering into shape and passes the hole and be fixed on the push rod, tup is located at outside the shell, this tup and the bell coupling that is located on the shell;

Described push rod is a strip shape body, is provided with the draw-in groove with the push rod coupling in the shell.

Described bell is fixedlyed connected with shell by the bell post.

By a kind of timer of the technical solution of the utility model design, have simple in structurely, easy to use, volume is little, the fullmouthed advantage of quarter-bell.

Embodiment

In conjunction with Fig. 1, Fig. 2 the utility model is described further.

Of the present utility model a kind of timer as shown in Figure 1 and Figure 2, comprise bell 4, movement 2, shell 1, main shaft 10, beat hammer 6 and static contact spring piece 8, movement 2 is fixed in the shell 1, main shaft 10 is fixedlyed connected with movement cam 11, cam 11 is provided with groove 14, contacts with movable contact spring 12 with groove coupling and the push rod 13 that is slidingly connected to be connected.Bell 4 is fixedlyed connected with shell 1 by bell post 3, plays hammer 6 and is divided into tup 5 and hammer body 9.1 has a hole 7 on the shell, and hammer body 9 passes hole 7 and is fixed on the push rod 13, and tup 5 is located at outside the shell 1, and is complementary with bell 4.Push rod 13 is a strip shape body, is provided with the draw-in groove 15 with push rod 13 couplings in the shell 1.

Timer needs regularly, a selected earlier timing angular turn main shaft 10, the cam 11 of fixedlying connected with main shaft 10 also rotates, go out groove 14 with push rod 13 escapes of groove 14 couplings, whole push rod 13 is upwards pushed up by cam 11, and push rod 13 upwards slides by draw-in groove 15, and move on the right side of playing hammer 6 past bells 4 on the push rod 13, the movable contact spring 12 that is connected with push rod 13 contacts moves up and is connected with static contact spring piece 8, and whole timing mechanism is started working.

Timing one arrives, and the cam 11 that is connected with main shaft 10 resets, and the push rod 13 rebound groove 14 of taking advantage of a situation, push rod 13 are rapidly to lower slider, and the movable contact spring 12 that is connected with push rod 13 contacts disconnects with static contact spring piece 8, and beating on the push rod 13 hammered 6 into shape and also beaten bell 4 generation the tinkle of bells rapidly.

Claims (3)

1, a kind of timer, comprise the movement (2) in shell (1) and the shell (1), main shaft (10) is fixedlyed connected with movement cam (11), movement cam (11) is provided with groove (14), contact is connected the push rod (13) that mates with groove (14) and be slidingly connected with movable contact spring (12), it is characterized in that described shell (1) is provided with a hole (7), the hammer body (9) of playing hammer (6) passes hole (7) and is fixed on the push rod (13), tup (5) is located at outside the shell (1), this tup (5) and bell (4) coupling that is located on the shell (1).
