Description

Technical Field

[0001] The utility model relates to the technical field of wall clocks, in particular to a heat-dissipating and dust-proof wall clock back shell. Background Art

[0002] A wall clock refers to a clock hung on the wall. It was first evolved from a tower clock. A wall clock also needs to be divided into a dial and a back case. The back case is responsible for assisting the wall clock to be hung on the wall. At the same time, a movement is installed in the back case, and the movement can be used to achieve the normal operation of the wall clock.

[0003] In the prior art, the Chinese patent with authorization announcement number CN212083914U discloses a sealed moisture-proof wall clock case, whose structure includes a pendulum box, a rotating shaft, an hour hand, a sealed moisture-proof mechanism, a wall clock handle block, a nail groove, a digital needle dial, a minute hand, a second hand, and a pendulum. The upper end of the pendulum box is connected to the lower end of the sealed moisture-proof mechanism. The utility model is a sealed moisture-proof wall clock case. The digital needle dial is structurally installed inside the dial groove and aligned with the shaft hole on the surface so that the rotating shaft can be accurately embedded. Furthermore, a rubber sealing ring is provided on the outside of the dial groove to improve the internal sealing air and prevent the penetration of moisture from the outside. Further, a moisture-proof filling ring is provided at the rear end and cooperates with the inner groove cavity so that the space inside the movement groove can obtain a better sealed moisture-proof effect. A sponge gasket plate is installed on the outer ring of the movement groove to absorb the moisture entering the interior with a high density to reduce water vapor, so that the internal components are reduced from the erosion of external humid air to ensure the overall service life.

[0004] The above-mentioned mechanism is equipped with a sponge gasket plate on the outer ring of the movement groove, which can absorb the moisture entering the interior with a high density to reduce water vapor. However, in actual use, the sponge gasket will absorb water vapor until it itself becomes damp. In this case, the outer ring of the movement groove is always surrounded by the damp sponge gasket, which will cause damage to the movement groove itself and affect its service life. At the same time, when in use, the movement will generate a certain amount of heat during continuous work. In hot weather, heat accumulation will cause the applicability of the movement to decrease, thereby shortening its service life. Utility Model Content

[0005] The utility model aims to provide a heat-dissipating and dust-proof wall clock back case to solve the problem in the above-mentioned background technology that a movement will generate a certain amount of heat during continuous operation, and the heat accumulation will cause the applicability of the movement to decrease during use, thereby shortening the service life.

[0006] To achieve the above object, the utility model provides the following technical solutions: a heat dissipation and dustproof wall clock back shell, comprising a wall clock back shell body and a hanging hole fixedly connected to one end of the top end of the wall clock back shell body, a heat dissipation shell is fixedly connected to the middle position of the top end of the wall clock back shell body, and an organic core groove is provided on the inner side of the heat dissipation shell;

[0007] The outer side of the heat dissipation shell is provided with a dustproof ring, and one end of the dustproof ring is connected to the back shell body of the wall clock. The inner side of the dustproof ring is provided with a dustproof mechanism for cleaning the surface of the heat dissipation shell. The dustproof mechanism includes a slide groove, and the slide groove is opened on the inner side of the dustproof ring. The inner side of the slide groove is slidably connected with a slider.

[0008] Both ends of the wall clock back shell body are provided with first limit blocks, and both ends of the dial shell are provided with a clamping mechanism for limiting and connecting the wall clock back shell body and the dial shell.

[0009] Furthermore, one end of the top of the slider is fixedly connected to a pull rod, the top of the slider at one end of the pull rod is fixedly connected to a mounting box, and the interior of the mounting box is fixedly connected to a cleaning brush via a buffer spring.

[0010] Furthermore, the top of the interior of the installation box is connected to the top of the buffer spring, and an elastic structure is formed between the buffer spring and the cleaning brush.

[0011] Furthermore, the inner side of the cleaning brush fits with the outer side of the heat dissipation shell, and the bottom end of the cleaning brush passes through and extends to the bottom of the installation box.

[0012] Furthermore, a heat dissipation hole is provided on the surface of the heat dissipation shell, and the cross section of the heat dissipation hole is in an "L" shape.

[0013] Furthermore, the locking mechanism includes a second limit block, and the second limit block is fixedly connected to the two ends of the dial shell, the second limit block and the first limit block match each other, one side of the second limit block is locked with a locking block, and the surface of the first limit block is provided with a locking groove matching the locking block.

[0014] Furthermore, a return spring is wound around the outer side of the clamping block, and the return spring is connected to one side of the second limit block:

[0015] 1. By installing the movement inside the movement slot, a certain gap is reserved between the movement slot and the movement for heat dissipation. At the same time, the movement slot is arranged inside the heat dissipation shell, and a certain space is arranged between the heat dissipation shell and the outer wall of the movement slot for heat dissipation. At the same time, the heat will finally be dissipated through the heat dissipation holes to avoid heat accumulation inside the movement slot to affect the long-term use of the movement, thereby ensuring the stable operation of the movement. The use of stable heat dissipation can effectively extend the service life of the movement;

[0016] Furthermore, the shape of the heat dissipation hole can increase the contact area between the movement slot and the outside air, and dissipate the heat of the movement slot from different directions, so as to better achieve heat dissipation, reduce heat accumulation, and ensure the stable use of the movement;

[0017] Furthermore, the dustproof ring is set on the outer side of the heat dissipation shell to block dust, reduce dust from entering the interior of the rear shell body of the wall clock through the heat dissipation holes, and prevent dust from falling on the outside of the movement groove and being inconvenient to clean. At the same time, the slider is engaged in the inside of the slide groove, and the pull-out rod is held and rotated along the slide groove to clean the dust on the surface of the heat dissipation shell, so that the dust on the surface and side of the heat dissipation shell can be cleaned by the cleaning brush, thereby effectively reducing dust residue, and the slide groove and the slider can also be quickly separated to avoid affecting the normal use of the wall clock;

[0018] 2. Align the positions of the dial case and the back case of the wall clock, and then rotate the dial case so that the first limit block can be engaged with the inside of the second limit block, so as to realize the engagement and splicing between the back case of the wall clock and the dial case. When the movement is damaged, the back case of the wall clock can be quickly disassembled, and the movement inside the back case of the wall clock can be taken out for replacement, which increases the flexibility during use;

[0019] Furthermore, during the engagement process of the first limit block and the second limit block, the position of the block can be adjusted so that the block and the slot can be engaged, thereby performing secondary position restriction on the first limit block and the second limit block, so that the first limit block and the second limit block can be more firmly engaged, thereby avoiding separation between the back shell body and the dial shell of the wall clock due to twisting.
