Description

Technical Field

[0001] The utility model relates to the technical field of instrument protection, in particular to a protection device for an instrument. Background Art

[0002] When the instrument is in use, a protective box should be placed outside the instrument for protection. In winter, the instrument protection box should be sealed to keep the instrument warm and prevent it from freezing. In summer, the instrument protection box should be ventilated to dissipate heat and prevent the instrument's circuit board from malfunctioning due to excessive temperature. Therefore, the existing instrument protection box is provided with a movable door. When the seasons change, maintenance personnel need to remove or install the movable door. After removal, the movable door needs to be transported and stored in a designated warehouse. Both transportation and storage incur costs, which is not conducive to cost saving. Of course, some instrument protection boxes also have movable doors hinged to the box body. They are often open for ventilation in summer and often closed for warmth in winter. Although the hinged door does not need to be removed or installed and does not incur transportation and storage costs, the door is only used in winter and is always open in other seasons. The door does not play any role and is very wasteful. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the valve at the vent of the instrument box is not easy to remove, which is not conducive to the heat transfer in the box;

[0005] As an improvement, the first locking mechanism and the second locking mechanism have the same structure. The first locking mechanism includes an L-shaped bracket, which is fixedly connected to the outer wall of the box body. A threaded sleeve is provided at the end of the L-shaped bracket away from the box body, and a threaded rod is provided in the threaded sleeve. A limit head is provided at one end of the threaded rod, and a handle head is provided at the end of the threaded rod away from the limit head, and a connecting rod is vertically provided on the handle head.

The problems to be solved by this application are described in detail in the following utility model content and specific implementation methods, and the technical problems to be solved by the technical solution are clarified, and it is determined that the technical solution of this application has beneficial effects relative to the objective prior art.

[0019] See also Figures 1-4 , an embodiment provided by the utility model:

[0020] A protective device for an instrument includes a box body 1, a first vent 101 is provided on the front of the box body 1, and a second vent 102 is provided at the bottom end, a first thermal insulation valve 3 is provided on the outside of the first vent 101, a support plate 4 is provided on the outer wall of the box body 1, the first thermal insulation valve 3 is arranged at the top of the support plate 4, and a first locking mechanism 5 is provided on both sides of the upper part of the first thermal insulation valve 3, a second thermal insulation valve 7 is provided on the outside of the second vent 102, and a second locking mechanism 10 for limiting the second thermal insulation valve 7 is provided at the bottom end of the box body 1, a heat dissipation cover 8 is provided on the inside of the second vent 102, and a heat dissipation fan 9 is provided inside the heat dissipation cover 8.

[0021] The first locking mechanism 5 and the second locking mechanism 10 have the same structure. The first locking mechanism 5 includes an L-shaped bracket 501, which is fixedly connected to the outer wall of the box body 1. A threaded sleeve 502 is provided at the end of the L-shaped bracket 501 away from the box body 1. A threaded rod 503 is provided in the threaded sleeve 502. A limit head 504 is provided at one end of the threaded rod 503. The limit head 504 is in the shape of a suction cup, which is conducive to the adsorption of the limit head 504 and the valve; and a handle head 505 is provided at the end of the threaded rod 503 away from the limit head 504, and a connecting rod 506 is vertically provided on the handle head 505.

[0022] A slot 401 is provided at the top of the support plate 4 , and the bottom end of the first heat-insulating valve is disposed in the slot 401 .

[0023] Both sides of the first heat-insulating valve 3 and the second heat-insulating valve 7 are provided with a waterproof layer.

[0024] Four brackets are provided at the top of the box body 1 , and the brackets are distributed in a rectangular shape. A canopy 2 is provided at the top of the brackets, and a placement groove 103 is provided at the top of the box body 1 .

[0025] Four supporting legs 6 are provided at the bottom end of the box body 1 . The supporting legs 6 are distributed in a rectangular shape, and the length of the supporting legs 6 is greater than the length of the threaded rod 503 .

[0026] In actual use of the above structure, during the freezing period in winter, the first and second vents are closed to reduce heat loss, play a role in heat preservation, and avoid freezing and blockage of instruments and pipelines;

[0027] During the non-freezing period, the first heat-insulating valve and the second heat-insulating valve are removed from the first vent and the second vent, respectively. Under the action of the cooling fan 9, air enters the box 1 from the first vent 101 and flows out from the second vent 102, taking away the heat in the box 1. The temporarily unused first heat-insulating valve 3 and the second heat-insulating valve 7 can be placed in the placement slot 401 at the top of the box 1 for storage.

[0028] With reference to the drawings in the specification, the specific operation of the first locking mechanism and the second locking mechanism is that the staff member holds the connecting rod 506 and rotates the connecting rod 506. The connecting rod 506 drives the handle head 505 to rotate, and the handle head 505 drives the threaded rod 503 to rotate. The threaded rod 503 approaches the corresponding first thermal insulation valve 3 / second thermal insulation valve 7, presses and restricts the first thermal insulation valve 3 / second thermal insulation valve 7, so that the first thermal insulation valve 3 / second thermal insulation valve 7 is fitted with the box body 1, completing the blocking of the first vent 101 / second vent 102;

[0029] When the temperature sensor shows that the temperature inside the box body 1 is not too high and only a small gap is needed, the threaded rod on the first locking mechanism 5 is rotated outward, and the limit head is separated from the first thermal insulation valve 3, so that a gap is left between the first thermal insulation valve 3 and the box body 1. The upper part of the first thermal insulation valve 3 is moved outward, and the first thermal insulation valve 3 is tilted, so that the first vent 101 can achieve a partial ventilation effect;

[0030] In order to ensure that the first thermal insulation valve and the second thermal insulation valve can be disassembled and assembled without worrying about the front and back sides, waterproof layers are provided on both sides of the first thermal insulation valve and the second thermal insulation valve.

[0031] Those skilled in the art will readily appreciate other embodiments of the present application after considering the specification and practicing the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered merely as exemplary, and the true scope of this application is indicated by the claims.

[0032] It should be understood that the present application is not limited to the precise structure described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The above-described embodiments of the present application do not constitute a limitation on the scope of protection of the present application.
