Description
Technical Field
[0001] The utility model relates to the technical field of timers, in particular to a DF timer with internal wiring. Background Art
[0002] The existing timer has the problem of low scale accuracy or inconvenience for users to observe the scale accuracy. In addition, the existing timer does not have the function of preventing misoperation. Utility Model Content
[0003] The technical problem to be solved by the present invention is: in order to overcome the above problems, a DF timer with internal wiring is provided, which solves the above problems.
[0004] The utility model solves the technical problem by adopting the following technical solutions:
[0005] A DF timer with internal wiring includes a timer body and a timer knob cooperating with the timer body. An extended timer force storage shaft is provided on the timer body for storing force on a coil spring inside the timer body after rotation. The timer knob is mounted on the timer force storage shaft, and a buffer separation device is provided between the timer knob and the timer force storage shaft for separating the timer knob from the timer force storage shaft.
[0006] Preferably, a hexagonal socket is provided in the timer power storage shaft, a countersunk hole is provided in the timer knob, and a hexagonal pin for being inserted into the hexagonal socket is provided in the timer knob.
[0007] Preferably, a chassis is fixedly provided at the bottom of the timer power storage shaft, and the chassis rotates synchronously with the timer power storage shaft.
[0008] Preferably, a spring is fixed on the chassis, and the other end of the spring is fixed to the bottom of the timer knob. Under the action of the spring, the hexagonal pin is not inserted into the hexagonal socket, and rotating the timer knob cannot trigger the timer power storage shaft to rotate. After releasing the timer knob, the timer knob will return to its original position under the action of the spring. When timing is required, the timer knob is pressed down so that the hexagonal pin is inserted into the hexagonal socket and then rotated to rotate the timer power storage shaft.
[0009] Preferably, timer scales are provided at annular intervals on the outer side of the upper end surface of the timer body.
[0010] Preferably, an observation arm is fixedly provided on the side wall of the timer knob, and a convex lens is fixedly provided at the front end of the observation arm for more convenient and accurate observation of the corresponding scale of the timer knob being turned.
[0011] The advantages and positive effects of the utility model are: convenient and accurate observation of the scale, improved timing accuracy, and prevention of unnecessary timing caused by erroneous rotation. BRIEF DESCRIPTION OF THE DRAWINGS
