[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] The technical solution of the utility model proposes a cap-brim type waterproof structure for instruments and meters.

[0025] Reference Figures 1 to 3 In this embodiment, the brim-type waterproof structure of the instrument is arranged between the instrument housing 1 and the display cover 2. The display cover 2 includes a first connecting section 21 and a second connecting section 22. The first connecting section 21 is detachably connected to the inner wall of the instrument housing 1, and is characterized in that it includes:

[0026] The brim structure 3 is disposed between the second connecting section 22 and the instrument housing 1 . The brim structure 3 is connected to the outer side of the instrument housing 1 . The brim structure 3 surrounds the outer side of the instrument housing 1 and extends in a direction away from the instrument housing 1 .

[0027] Optionally, in the present embodiment, the brim type waterproof structure for the instrument is arranged between the instrument housing 1 and the display cover 2, wherein the display cover 2 comprises a first connecting section 21 and a second connecting section 22, the first connecting section 21 and the inner wall of the instrument housing 1 are detachably connected, that is, the first connecting section 21 can be connected to the inner wall of the instrument housing 1 by a threaded connection or a snap-on connection, which is not limited here, wherein an instrument circuit is arranged in the instrument housing 1, and the detachable connection between the first connecting section 21 and the instrument housing 1 facilitates the inspection and maintenance of the circuit; the brim structure 3 is arranged between the second connecting section 22 and the instrument housing 1, wherein the brim structure 3 is connected to the outer side of the instrument housing 1, and the brim structure 3 surrounds the outer side of the instrument housing 1 and extends in a direction away from the instrument housing 1, and through the design of the brim structure 3, a brim is added around the connection between the instrument housing and the display cover 2, which plays a role of auxiliary waterproofing, that is, as the first layer of waterproof protection for the instrument, the main waterproofing is achieved by the waterproof structure between the display cover 2 and the instrument housing 1; refer to Figure 1 and Figure 2 When rainwater flows through point A, it is diverted at point B. Part of the water flows from point B to point E. This part of the water slides down along the brim structure 3, which plays an auxiliary waterproofing effect. Another part of the rainwater flows along point A to points B and C, and flows to the waterproof structure of the display cover 2 and the instrument housing 1. The waterproof structure of the display cover 2 and the instrument housing 1 plays a main waterproofing role, preventing this part of the rainwater from entering the device. Through the arrangement of the above-mentioned device and structure, auxiliary waterproofing of the instrument is achieved, preventing rainwater from entering the inside of the instrument when the main waterproof structure is damaged or fails, causing damage to the circuit and components.

[0028] In this embodiment, the second connecting section 22 is arranged in a stepped shape at the top of one side close to the instrument housing 1. Figure 2 The inclined surface of the step is arranged to be inclined downward in a direction away from the instrument housing 1. Through the setting of the step, when rainwater flows from point B to point C, the inclination of the step and the inclined surface makes it difficult for rainwater to reach point C from point B, thereby reducing the possibility of rainwater entering the main waterproof structure from point C, playing a role of auxiliary waterproofing, and being able to reduce the waterproofing pressure of the main waterproofing structure.

[0029] In this embodiment, the brim type waterproof structure for instruments and meters also includes a first sealing rubber ring 41, which is sleeved on the outside of the first connecting section 21, and the first sealing rubber ring 41 is arranged between the first connecting section 21 and the instrument housing 1. By adding the first sealing rubber ring 41 at the connection between the first connecting section 21 and the instrument housing 1, when the first connecting section 21 and the instrument housing 1 are connected, the first sealing rubber ring 41 is abutted and squeezed, so that a seal is formed between the first connecting section 21 and the instrument housing 1, preventing part of the water entering the main waterproof structure from C from flowing into the interior of the instrument. In other embodiments, O-rings or plastic seals can also be used as seals, which are not limited here.

[0030] In this embodiment, the hat-brim waterproof structure for instruments and equipment also includes an audible and visual alarm 5, which is connected to the instrument housing 1 and partially exposed outside the instrument housing 1. The audible and visual alarm 5 in the instrument and equipment is usually used to emit two alarm signals, sound and light, under specific circumstances, and is usually used to monitor pressure, temperature, humidity, etc. to ensure the normal operation of the instrument and equipment; further, a second sealing rubber ring 42 is provided at the connection between the audible and visual alarm 5 and the instrument housing 1, and the second sealing rubber ring 42 is sleeved on the outside of the audible and visual alarm 5; refer to Figure 3 When external rainwater flows through point a, it is diverted at point b. Part of the water flows from point b to point e. This part of the water slides down along the brim structure 3, which plays an auxiliary waterproofing effect. Another part of the rainwater flows along point a to point b and point b, and flows to the waterproof structure of the sound and light alarm 5 and the instrument housing 1. The waterproof structure of the sound and light alarm 5 and the instrument housing 1 plays the main waterproofing role to prevent this part of the rainwater from entering the device. The waterproof structure of the sound and light alarm 5 and the instrument housing 1 is a second sealing rubber ring 42, that is, the sound and light alarm 5 and the instrument housing 1 abut and squeeze the second sealing rubber ring 42 to form a sealing structure to prevent part of the water that enters the main waterproof structure from point c from flowing into the inside of the instrument.

[0031] In this embodiment, the brim structure 3 and the instrument housing 1 are integrally formed, and the first connecting section 21 and the second connecting section 22 are integrally formed. The integrally formed setting facilitates production and processing, and the connection between the device structures is more stable. Further, in this embodiment, the brim waterproof structure for the instrument also includes a water-absorbing gasket, which is provided with two groups, one group of water-absorbing gaskets is provided between the first sealing rubber ring 41 and the instrument housing 1, and the other group of water-absorbing gaskets is provided between the second sealing rubber ring 42 and the sound and light alarm 5. When the water flows into the main waterproof structure along point C or point c, the first sealing rubber ring 41 or the second sealing rubber ring 42 isolates the water flow, and the water-absorbing gasket absorbs the inflowing water to prevent the water from accumulating and affecting the instrument. It is only necessary to replace the water-absorbing gasket regularly to further prevent rainwater from entering the instrument.

[0032] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
