Description

[Technical field]

[0001] The utility model relates to the technical field of clocks and watches, in particular to a protective clock and watch back cover. [Background technology]

[0002] Clocks are a general term for clocks and watches, both of which are precision instruments for measuring and indicating time. Existing clocks include large hanging clocks and slightly smaller standing clocks, which have brought a lot of convenience to people's lives. People arrange their lives according to time in an orderly manner without chaos.

[0003] Conventional watches or clocks are mainly composed of a front dial, a movement, and a back cover. The movement is installed between the front dial and the back cover, and a battery cover is movably installed on the back cover. The existing battery cover and the back cover are movably connected mainly in two ways:

[0004] One is snap-on connection. For example, the prior art CN 217305720 U discloses a clock that integrates a radio alarm clock, including a clock body, a protruding block, a battery compartment, a lithium battery, and a battery cover. The back of the clock body is fixedly connected with a protruding block, and the inside of the protruding block is provided with a battery compartment, and the outside of the battery compartment is snap-on with a battery cover; the bottom of the battery cover is fixedly connected with a plug-in block, and the top of the battery cover is fixedly connected with an elastic card block, which is snap-on to the top of the battery compartment. By setting the battery cover, when the lithium battery is damaged and the battery cover needs to be opened, the elastic card block can be pressed down to remove the battery cover and replace the lithium battery. The snap-on connection method has the following defects: no tools are required, and the battery cover can be opened with one hand. When children play with the clock, they can also easily open the battery cover and buckle out the battery, so the protection performance of the battery cover is not high.

[0005] The other is to use screws to lock. For example, the prior art CN103901761A discloses a flying alarm clock, including a clock body, a circuit board, a battery, and a battery cover. The clock body is provided with a battery compartment for placing batteries, and the battery cover is used to close the battery compartment. The battery cover is detachably fixed to the clock body, and specifically, the battery cover is fixed to the clock body by screws. The connection method of using screws to lock has the following defects: since the screws are small components and are not integrated with the battery cover, the screws are easy to lose after removing the screws to open the battery cover; the screws may also fall off after multiple disassembly and assembly, causing children to swallow them by mistake, and there is also the problem of low protection performance.

[0006] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which led to the emergence of this case. [Contents of the utility model]

[0007] The utility model aims to solve the technical problems in the prior art that the battery cover can be opened with one hand, but the screws are easily lost or there is a risk of accidental swallowing after opening with a tool, resulting in low protective performance of the battery cover. The utility model provides a protective watch back cover that does not require any additional accessories except for the back cover main board and the battery cover. The battery cover cannot be opened with one hand and can only be opened with the help of a tool and the hand. It has the advantage of high protective performance.

[0008] The utility model is implemented as follows: a protective watch back cover comprises a back cover main board and a battery cover; the two sides of the battery cover extend outward to form a first plate and a second plate, the first plate and the second plate are respectively located on the opposite sides of the battery cover, and a convex column is formed on the upper surface of the first plate; a through hole for inserting the convex column is formed on the back cover main board; when the battery cover and the back cover main board are covered, the convex column is inserted from the through hole at one end close to the movement.

[0009] Furthermore, a battery installation cavity is formed on the rear cover mainboard, and a battery enclosure is provided in the battery installation cavity, and the battery enclosure divides the battery installation cavity into an inner cavity for placing the battery and an outer cavity for the first plate and the second plate to slide; the through hole is formed through the outer cavity.

[0010] Furthermore, the battery enclosure includes an enclosure wall and an outer top plate; the enclosure wall is provided with a first connection port connected to the external cavity, and a second connection port connected to the external cavity, and the first connection port and the second connection port are arranged relative to each other; the outer top plate is formed outside one end of the enclosure wall and is fixedly connected to the back cover mainboard.

[0011] Furthermore, the rear cover main board is located at the first connection port and has a limiting portion formed downward; and the upper surface of the first plate is formed with a first locking portion.

[0012] Furthermore, a limiting portion is formed downwardly on the rear cover main board at the second connection port; and a first locking portion is formed on the upper surface of the second plate.

[0013] Furthermore, the limiting portion includes a first limiting surface and a second limiting surface; the first engaging portion includes an inclined surface and a fitting surface.

[0014] Furthermore, the battery cover, the first plate and the second plate are integrally injection molded by plastic.

[0015] Furthermore, a plurality of extension plates extending outward are formed on the periphery of the battery installation cavity, and a winding space is formed between the extension plates and the rear cover mainboard.

[0016] Furthermore, the plurality of extension plates are arranged at equal intervals.

[0017] The advantages of the utility model are as follows: the protective watch back cover of the utility model does not require any additional accessories except the back cover main board and the battery cover. The battery cover can be removed from the back cover main board only by pushing the boss downward out of the through hole with the help of a tool and pushing the battery cover with the hand at the same time. The battery cover can only be removed by the coordinated operation of the tool and the hand, and the battery cover cannot be opened with one hand. The utility model has better protection performance for children and can avoid the risk of children accidentally swallowing batteries.
