Technical Field
[0001] This utility model relates to the field of metering box technology, specifically a drawer-type waterproof metering box. Background Technology
[0002] With the rapid development of power systems and the advancement of smart grid construction, the operational reliability and environmental adaptability of power metering equipment, as the core device for power metering and management, are receiving increasing attention. Metering boxes used outdoors or in humid environments must possess excellent waterproof and dustproof performance to avoid equipment failures, data errors, or even safety accidents caused by rainwater penetration and dust accumulation.
[0003] Traditional metering boxes often use a combination of rubber sealing strips and metal pressure plates for sealing, achieving a seal through mechanical pressure. However, the sealing strips are prone to creep under long-term compression, leading to seal failure. The fit gap between the metal pressure plate and the box body is difficult to control precisely, and leakage channels can easily be created due to thermal expansion and contraction when the temperature changes. At the same time, during the opening and closing process, the friction between the sealing strip and the edge of the box body will accelerate the wear of the sealing material and shorten the service life of the equipment.
[0004] In addition, existing technologies have significant shortcomings in dustproof design. Although some products have dustproof covers at the observation window, they mostly use magnetic or snap-on fixing methods. During use, the magnetic attraction is easily affected by temperature and humidity, and the magnetic force weakens significantly after long-term use. At the same time, the snap-on structure is prone to plastic deformation during frequent opening and closing, resulting in incomplete closure. This allows dust to enter the observation window, affecting the readings and resulting in poor performance.
[0005] Therefore, in order to address the above problems, the applicant needs to design a drawer-type waterproof metering box to solve the problem. Utility Model Content
[0006] The purpose of this utility model is to provide a drawer-type waterproof metering box to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a drawer-type waterproof metering box, comprising a metering box body, and a waterproof shell provided on the outer side of the metering box body. It also includes: a sealing mechanism located on the outside of the metering box body, and the sealing mechanism is used to open or close the waterproof shell. The sealing mechanism includes a fixing block fixedly connected to the waterproof shell, and a return spring is fixedly installed on the fixing block. A sealing cover is fixedly installed at the end of the return spring away from the fixing block, and the sealing cover cooperates with the waterproof shell to close the opening end of the waterproof shell. An observation window is provided on the metering box body, and a dustproof mechanism is provided on the observation window. The dustproof mechanism includes a base fixedly connected to a waterproof shell, a dustproof cover is movably provided on the base, and a handle is fixedly provided on the dustproof cover.
[0008] Furthermore, a groove is provided on the inner side of the sealing cover, and a guide block is slidably disposed inside the groove, and the guide block is fixedly connected to the waterproof shell.
[0009] Through the above structural design, the sliding cooperation between the guide block and the slide groove ensures that the sealing cover moves smoothly and prevents it from deviating or getting stuck.
[0010] Furthermore, a sealing block is fixedly provided on the outer side of the waterproof shell, and the sealing block is fitted and sealed to the opposite surface of the sealing cover.
[0011] Through the above structural design, the sealing block and the sealing cover fit together to provide a sealing surface, effectively enhancing the overall waterproof performance.
[0012] Furthermore, the sealing block is provided with a groove, and a rubber strip is fixedly provided on the sealing cover, and the rubber strip is adapted to the groove.
[0013] Through the above structural design, the combination of the rubber strip and the groove forms multiple sealing barriers, improving the water-proof capability at the interface.
[0014] Furthermore, a connector is fixedly provided on the dust cover, and a fixed shaft is rotatably provided on the connector. A bearing seat is fixedly provided on the fixed shaft, and the bearing seat is fixedly connected to the waterproof shell.
[0015] The above structural design, through the rotational connection achieved by the fixed shaft and bearing seat, makes the dust cover flexible and durable in opening and closing.
[0016] Furthermore, the dust cover is provided with a locking groove, and a locking pin is provided in the locking groove, and the locking pin is threadedly connected to the base.
[0017] Through the above structural design, the threaded connection between the locking pin and the base provides a reliable mechanical locking force, ensuring that the dust cover closes securely.
[0018] Furthermore, a fixing sleeve is fixedly provided on the locking pin, and the fixing sleeve cooperates with the dust cover to lock the dust cover and the base.
[0019] Through the above structural design, the fixing sleeve increases the contact area with the dust cover, making the locking force distribution more uniform and the locking more reliable.
[0020] Furthermore, the fixing sleeve is made of silicone rubber.
[0021] Through the above structural design, the silicone rubber fixing sleeve has good elasticity and weather resistance, and can adapt to temperature changes while maintaining an effective seal.
[0022] Compared with the prior art, the beneficial effects of this utility model are: This drawer-type waterproof metering box enhances its overall protective performance through a sealing mechanism and a dustproof mechanism. The sealing mechanism utilizes a return spring and guide groove to ensure precise and stable closure of the sealing cover. Combined with a multi-layered sealing interface formed by rubber strips and grooves, it effectively resists moisture penetration, overcoming the problems of creep and thermal expansion / contraction leakage inherent in traditional sealing strips. Meanwhile, its dustproof mechanism employs a combination of mechanical thread locking and weather-resistant silicone rubber material to provide a stable and reliable locking seal for the observation window. This completely eliminates the risk of incomplete closure caused by component aging or deformation in magnetic or snap-on designs. Thus, while ensuring ease of operation, it enhances the long-term operational performance and service life of the equipment in harsh environments. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figures 1-4As shown, this utility model discloses a drawer-type waterproof metering box, including a metering box body 1, and a waterproof shell 10 is provided on the outside of the metering box body 1. It also includes: a sealing mechanism 2 provided on the outside of the metering box body 1, and the sealing mechanism 2 is used to open or close the waterproof shell 10. The sealing mechanism 2 includes a fixing block 23 fixedly connected to the waterproof shell 10, and a return spring 24 is fixedly provided on the fixing block 23. A sealing cover 20 is fixedly provided at the end of the return spring 24 away from the fixing block 23, and the sealing cover 20 cooperates with the waterproof shell 10 to close the opening end of the waterproof shell 10; an observation window 11 is provided on the metering box body 1, and a dustproof mechanism 3 is provided on the observation window 11. The dustproof mechanism 3 includes a base 30 fixedly connected to the waterproof shell 10, a dustproof cover 31 is movably provided on the base 30, and a handle 32 is fixedly provided on the dustproof cover 31.
[0027] The inner side of the sealing cover 20 is provided with a groove 21, and a guide block 22 is slidably arranged inside the groove 21. The guide block 22 is fixedly connected to the waterproof shell 10. The sliding fit structure between the guide block 22 and the groove 21 provides precise guidance for the linear movement of the sealing cover 20, effectively avoiding the skewing or jamming caused by uneven force during the opening and closing of the sealing cover 20, and ensuring the smoothness and reliability of the sealing action.
[0028] A sealing block 25 is fixedly installed on the outer side of the waterproof shell 10, and the sealing block 25 is in close contact with the opposite surface of the sealing cover 20. The sealing block 25 and the sealing cover 20 form a tight contact surface, which can effectively compensate for the potential deformation of the main sealing component and enhance the waterproof capability of the metering box in spray or immersion environments.
[0029] The sealing block 25 is provided with a groove 26, and the sealing cover 20 is fixedly provided with a rubber strip 27. The rubber strip 27 is adapted to the groove 26. The interlocking structure of the rubber strip 27 and the groove 26 forms an independent elastic sealing barrier, which can adapt to the slight deformation of the box. Even when the internal spring pressure is slightly reduced, the elastic compression of the rubber strip 27 can still maintain the sealing integrity at the interface, which greatly improves the safety of preventing water leakage.
[0030] A connector 33 is fixedly installed on the dust cover 31, and a fixed shaft 34 is rotatably installed on the connector 33. A bearing seat 35 is fixedly installed on the fixed shaft 34, and the bearing seat 35 is fixedly connected to the waterproof shell 10. Through the rotational connection mechanism formed by the fixed shaft 34 and the bearing seat 35, the dust cover 31 achieves a stable and low-wear opening and closing movement, ensuring the flexibility and durability of the mechanism under long-term and frequent use.
[0031] The dust cover 31 is provided with a locking groove 36, and a locking pin 37 is provided in the locking groove 36. The locking pin 37 is threadedly connected to the base 30. The dust cover 31 is fixed by the strong and stable locking force generated by the mechanical thread, which overcomes the problem of incomplete closure caused by magnetic force attenuation or environmental interference in the magnetic suction design, and ensures the locking and sealing reliability of the dust cover 31 under various working conditions.
[0032] A fixing sleeve 38 is fixedly provided on the locking pin 37, and the fixing sleeve 38 cooperates with the dust cover 31 to lock the dust cover 31 and the base 30. The fixing sleeve 38 increases the contact area between the locking pin 37 and the dust cover 31, so that the locking pressure can be evenly distributed, avoiding stress concentration from causing pressure damage to the dust cover 31 or the base 30, and making the locking state more stable, further improving the stability of the connection and the uniformity of the seal.
[0033] The fixing sleeve 38 is made of silicone rubber. The use of silicone rubber in the fixing sleeve 38 makes full use of the excellent high and low temperature resistance, aging resistance and elasticity retention of silicone rubber, ensuring that the locking parts can maintain good sealing performance and stable locking force when used for a long time in harsh outdoor climate environments, thus extending the maintenance cycle.
[0034] When using this drawer-type waterproof metering box, when it is necessary to close the box, the external force restriction is released, and the sealing cover 20 slides along the guide block 22 to compress the reset spring 24. Under the action of the spring tension, the sealing cover 20 is tightly pressed against the opening end of the waterproof shell 10. The rubber strip 27 on it is simultaneously embedded in the groove 26 of the sealing block 25, forming multiple mechanical and elastic seals, effectively blocking the intrusion channels of moisture and dust. When it is necessary to observe the data, the locking pin 37 can be unscrewed to release the fixation of the dust cover 31. The dust cover 31 can be opened by flipping the handle 32, and the reading can be taken through the observation window 11. Afterwards, the dust cover 31 can be reliably locked back onto the base 30 by the cooperation of the threaded locking pin 37 and the silicone rubber fixing sleeve 38, thereby realizing convenient and reliable waterproof and dustproof functions.
[0035] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
