Description
Technical field
The utility model belongs to Watch ＆ Clock Repair field, more particularly to a kind of watch rear cover opening device.
Background technology
Present watch rear cover is generally pressure-lift bonnet and spiral shell button bonnet, and in the majority with pressure-lift.For opening for pressure-lift bonnet
Open, we can typically be pried open with some hard small tools of the matter such as hard and thin blade, sharp tweezers, but the operation is only suitable for professional behaviour
Make personnel, opened for general staff using this method, it is easy to cause watch rear cover to scratch or damage, therefore this method
Inconvenient for operation, the scope of application is narrower.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of watch rear cover opening device, operates fairly simple side
Just, wrist-watch will not be caused to damage.
In order to solve the above technical problems, technical scheme is used by the utility model:A kind of watch rear cover opens dress
Put, include the sleeve of lower ending opening, sleeve upper end sets mounting groove, and pressing plate is arranged in mounting groove, pressing plate lower end and mounting groove
Between support spring is set, set pressing raised below pressing plate, pressing projects through the first spring and is connected with connecting rod one end, connects
Bar is rotatably coupled to sleeve inner by support shaft, and the connecting rod other end is connected by pin with handle of uncapping, and support shaft arrives
The distance of first spring is more than the distance to pin, and handle, at its lower end of uncapping sets crotch.
Connection second spring is tilted in preferable scheme, between the connecting rod and handle of uncapping.
In further scheme, connection draw ring on the upside of the pressing plate.
In preferable scheme, the sleeve lateral wall bottom sets foam-rubber cushion.
In preferable scheme, the sleeve lateral wall position relative with handle of uncapping sets opening.
In preferable scheme, the distance of the support shaft to the first spring is 2 ~ 3 times of support shaft to the distance of pin.
A kind of watch rear cover opening device provided by the utility model, by pressing down on pressing plate, pressing projection is to connecting rod
One end apply downward pressure, because connecting rod is the lever using support shaft as fulcrum, one end that connecting rod is connected with handle of uncapping
Motion upwards, in use, the crotch for handle, at its lower end of uncapping to be inserted to the indentation, there of watch rear cover, you can watch rear cover is opened.
The device will not cause to damage to wrist-watch, simple to operate.In preferable scheme, connection second is tilted between connecting rod and handle of uncapping
Spring, second spring are tensed and uncapped handle, and the handle that makes to uncap maintains a certain distance with connecting rod, prevents in pressing pressing plate opening hand
During watch back cover, the crotch of the related lower end of handle of uncapping departs from the breach of watch rear cover, ensures that crotch is in watch rear cover all the time
Indentation, there.Sleeve lateral wall bottom sets foam-rubber cushion, prevents sleeve bottom and watch dial contact damage table body.Sleeve lateral wall is with opening
The relative position of lid handle sets opening, can observe whether crotch is already inserted into watch rear cover breach, and convenient whole dress
The installation site put determines.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is sectional view of the present utility model.
In figure：Sleeve 1, pressing plate 2, the first spring 3, connecting rod 4, support shaft 5, pin 6, handle 7 of uncapping, second spring 8, draw
Ring 9, foam-rubber cushion 10, support spring 11, wrist-watch 12, mounting groove 101, opening 102, pressing projection 201, crotch 701.
Embodiment
In Fig. 1 ~ 2, a kind of watch rear cover opening device, include the sleeve 1 of lower ending opening, the upper end of sleeve 1 sets installation
Groove 101, pressing plate 2 are arranged in mounting groove 101, and support spring 3, the lower section of pressing plate 2 are set between the lower end of pressing plate 2 and mounting groove 101
Pressing projection 201 is set, and pressing projection 201 is connected by the first spring 3 with the one end of connecting rod 4, and connecting rod 4 can by support shaft 5
What is rotated is connected to inside sleeve 1, and the other end of connecting rod 4 is connected by pin 6 with handle 7 of uncapping, the spring of support shaft 5 to the first 3
Distance be more than to pin 6 distance, uncap the lower end of handle 7 set crotch 701.
Connection second spring 8 is tilted between the connecting rod 4 and handle 7 of uncapping.During 4 keep level state of connecting rod, the second bullet
The angle of spring 8 and connecting rod 4 is 30 °.
The upside of the pressing plate 2 connection draw ring 9.
The side wall bottom of sleeve 1 sets foam-rubber cushion 10.
The side wall of sleeve 1 position relative with handle 7 of uncapping sets opening 102.
The distance of the spring of support shaft 5 to the first 3 is 2 ~ 3 times of the distance that support shaft 5 arrives pin 6.
When specifically used, covered after whole device is placed on into wrist-watch 12, opening 102 and the notch alignment of bonnet, to
Upper drawing draw ring 9, pressing plate 2 move upwards, and pressing projection 201 drives connected one end of connecting rod 4 to be upturned, with hand of uncapping
