Description

Technical Field

[0001] The utility model relates to the field of timers, in particular to a timer with an astronomical time adjustment function. Background Art

[0002] As the name suggests, a timer is a device used for timing. The set time can be freely adjusted according to the needs of use. There are many types of timers, including timers for timed power off of electrical equipment.

[0003] When the timer is in use, the time is set by rotating the timing knob of the timer. However, since the timing knob protrudes from the timer and has no protective structure, the exposed timing knob is easily changed by accidental touch and the set time. The exposed timing knob may also be damaged by falling foreign objects, which is not conducive to the protection of the timing knob. Utility Model Content

[0004] The main purpose of the utility model is to provide a timer with an astronomical time adjustment function, which can effectively solve the problems in the background technology.

[0007] Preferably, the protective member includes a protective ring, an auxiliary ring, an insertion rod and a stop block. The rear surface of the protective ring is fixedly mounted with an insertion rod. There are three insertion rods, which are distributed in a triangular shape on the rear surface of the protective ring.

[0008] Preferably, a slot is provided on the front surface of the timer body and located on the periphery of the timing knob, and a movable slot is provided laterally on the front surface of the timer body and near both sides, a guide rod is fixedly installed inside the movable slot, a spring is provided on the surface of the guide rod, and a spring is also provided inside the slot.

[0009] Preferably, a support block is fixedly mounted on the rear surface of one end of the pressing block, and a sleeve block is fixedly mounted on the rear surface of the support block, and the sleeve block is sleeved on the surface of the guide rod.

[0010] Preferably, one end of the spring inside the movable groove is fixed to the sleeve block, and the other end of the spring is fixed to an inner end surface of the movable groove.

[0011] Preferably, the rear end of the insertion rod is embedded in the slot, a stop block is fixedly mounted on the rear surface of the insertion rod, and an auxiliary ring is fixedly sleeved on the surface of the protective ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the utility model, by arranging the timer body, the protective member and the pressure block to cooperate with each other, when it is necessary to rotate the timing knob, the protective member is pressed backward so that the timing knob protrudes from the protective member, and then the timing knob can be rotated. When the time is set, the external force pushing the protective member is released. When the protective member is pushed, it squeezes the spring in the slot. Therefore, after the external force pushing the protective member is released, the protective member will extend forward under the pushing action of the spring, so that the timing knob can be wrapped with the protective member, and the timing knob can be shielded and protected at this time.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4The timer shown has an astronomical time adjustment function, including a timer body 1, a plug 2 and a timing knob 4. The plug 2 is fixedly installed on the rear surface of the timer body 1, and a jack 3 is provided on the front surface of the timer body 1. The timing knob 4 is movably installed on the front surface of the timer body 1 and above the jack 3. A protective member 5 is movably installed on the front surface of the timer body 1 and outside the timing knob 4. Pressure blocks 7 are movably installed on the front surface of the timer body 1 and on both sides of the timing knob 4. An indicator light 6 is fixedly installed on the front surface of the timer body 1 and below one side of the timing knob 4.

[0021] The protective member 5 includes a protective ring 501, an auxiliary ring 502, an insertion rod 503 and a stop block 504. The rear surface of the protective ring 501 is fixedly installed with an insertion rod 503. There are three insertion rods 503, and the three insertion rods 503 are distributed in a triangle on the rear surface of the protective ring 501; a slot 101 is provided on the front surface of the timer body 1 and is located on the periphery of the timing knob 4. A movable groove 102 is provided on the front surface of the timer body 1 and is laterally opened near both sides. A guide rod 103 is fixedly installed inside the movable groove 102. A spring 104 is provided on the surface of the guide rod 103. A spring 104 is also provided inside the slot 101. The spring 104 has a pulling force on the sleeve block 702 close to the timing knob 4; a support block 701 is fixedly installed on the rear surface of one end of the pressure block 7 A sleeve block 702 is fixedly installed on the rear surface of the block 701, and the sleeve block 702 is sleeved on the surface of the guide rod 103; one end of the spring 104 inside the movable groove 102 is fixed to the sleeve block 702, and the other end of the spring 104 is fixed to the inner end surface of the movable groove 102. When the protective member 5 is squeezed close to the front surface of the timer body 1, the moved pressure block 7 can prevent the protective member 5 from rebounding under the action of the spring 104 inside the slot 101; the rear end of the insertion rod 503 is embedded in the slot 101, and a stop block 504 is fixedly installed on the rear surface of the insertion rod 503. An auxiliary ring 502 is fixed on the surface of the protective ring 501. The protective ring 501 can prevent the timing knob 4 from being accidentally touched and rotated, and can also prevent the timing knob 4 from being damaged after being dropped from top to bottom by foreign objects.

[0022] It should be noted that the present invention is a timer with an astronomical time adjustment function. When in use, when it is necessary to rotate the timing knob 4, the protective member 5 is pressed backward so that the timing knob 4 protrudes from the protective member 5, and then the timing knob 4 can be rotated. When the time is set, the external force pushing the protective member 5 is released. When the protective member 5 is pushed, it squeezes the spring 104 in the slot 101. Therefore, after the external force pushing the protective member 5 is released, the protective member 5 will extend forward under the pushing action of the spring 104, so that the timing knob 4 can be wrapped with the protective member 5, and the time can be set. To shield and protect the timing knob 4, when it is necessary to keep the timing knob 4 protruding from the protective member 5, the pressure block 7 is pulled while pushing the protective member 5, so that the pressure block 7 is away from the timing knob 4. When the protective member 5 is pushed to the maximum limit, the external force pulling the pressure block 7 is released. Since the spring 104 has a pulling force on the sleeve block 702 close to the timing knob 4, the pressure block 7 will move back to its original position after the external force pulling the pressure block 7 is released. The pressure block 7 that has moved back to its original position is located in front of the protective member 5, which can prevent the protective member 5 from moving forward under the pushing action of the spring 104 inside the slot 101.
