Description

A voltage regulator device with an explosion-proof structure Technical Field

[0001] This utility model relates to the technical field of voltage regulator equipment, and in particular to a voltage regulator equipment with an explosion-proof structure. Background Technology

[0002] A voltage regulator is a device used to regulate voltage. Its main function is to adjust the input voltage to meet the voltage requirements of different electrical appliances or equipment, and to automatically maintain a constant outlet pressure as gas consumption changes. In the electrical field, it is typically used to convert a certain voltage (such as 220V AC) into the voltage required by electrical appliances.

[0003] However, traditional voltage regulators use simple encapsulation structures, which result in poor sealing after installation, making it easy for the internal medium to leak. Furthermore, the medium can easily mix with air and cause an explosion. Therefore, there is an urgent need for a voltage regulator with an explosion-proof structure. Summary of the Invention

[0004] This utility model discloses a voltage regulator device with an explosion-proof structure, aiming to solve the problem that the traditional voltage regulator device uses a simple encapsulation structure, which has a poor sealing effect after installation, easily causing leakage of the internal medium of the voltage regulator. At the same time, it is easy to cause an explosion when it comes into contact with air and mixes. Therefore, there is an urgent need for a voltage regulator device with an explosion-proof structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A voltage regulator device with an explosion-proof structure includes a housing, an inner housing, and a coil assembly installed in the inner housing. It further includes: a sealing mechanism comprising a top cover on the top of the housing and a bottom cover on the bottom of the housing; flat grooves on the opposite outer walls of the top and bottom covers; sealing rings on the inner walls of the flat grooves; flat pads on the top and bottom of the housing; and lock heads evenly distributed between the housing and the inner housing; and a spring-loaded mechanism disposed on the inner housing.

[0007] In this solution, the sealing mechanism can tightly seal the encapsulation process of the voltage regulator. In actual use, during the connection between the top cover and bottom cover and the outer shell, the sealing ring can be deformed by the flat gasket and the flat groove, forming a sealing structure inside the flat groove. The elasticity of the sealing ring is used to fully fill the connection gap after fixing. In addition, the connection between the outer shell and the inner shell is connected by a locking head, and a wire harness connection seal is also formed when the wire harness passes through the locking head, thus improving the overall sealing performance of the voltage regulator.

[0008] In a preferred embodiment, the rebound mechanism includes a mounting groove disposed on the inner hole, a return spring disposed on the inner wall of the mounting groove, the lock head being slidably connected to the inner wall of the inner hole, and one end of the return spring being connected to the outer wall of one side of the lock head, the side of the lock head away from the inner hole being fitted into the inner wall of the outer hole, and a rubber ring being disposed on the outer wall of the lock head.

[0009] The spring-loaded structure allows the connection between the lock cylinder and the inner hole to be adjusted to an elastic connection, making the installation of the outer shell more convenient during the sealing process. At the same time, the rubber ring on the outside of the lock cylinder can be pressed against the connection with the outer hole under the elastic action, forming a secondary auxiliary seal.

[0010] As described above, a voltage regulator device with an explosion-proof structure includes a housing, an inner housing, and a coil assembly installed in the inner housing. It also includes: a sealing mechanism: the sealing mechanism includes a top cover disposed on the top of the housing and a bottom cover disposed on the bottom of the housing; flat grooves are provided on the outer walls of opposite sides of the bottom cover and the top cover; sealing rings are provided on the inner walls of the flat grooves; flat pads are provided on the top and bottom of the housing; and lock heads are provided at equal intervals between the housing and the inner housing; a spring-loaded mechanism: the spring-loaded mechanism is disposed on the inner housing. The voltage regulator device with an explosion-proof structure provided by this utility model has the technical effect of improving the sealing performance of the enclosure and the connection.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0016] The voltage regulator device with an explosion-proof structure disclosed in this utility model is mainly used in traditional voltage regulator devices. The encapsulation structure is simple, but the sealing effect is poor after installation, which can easily cause leakage of the medium inside the voltage regulator. At the same time, it can easily cause an explosion when it comes into contact with air. Therefore, there is an urgent need for a voltage regulator device with an explosion-proof structure.

[0017] Referring to Figures 1, 2, and 3, a voltage regulator device with an explosion-proof structure includes a housing 1, an inner housing 8, and a coil assembly installed in the inner housing 8. It also includes: a sealing mechanism: the sealing mechanism includes a top cover 2 disposed on the top of the housing 1 and a bottom cover 3 disposed on the bottom of the housing 1. Flat grooves are provided on the outer walls of opposite sides of the bottom cover 3 and the top cover 2. Sealing rings 6 are provided on the inner walls of the flat grooves. Flat pads 7 are provided on the top and bottom of the housing 1. Lock heads 9 are also provided at equal intervals between the housing 1 and the inner housing 8; and a spring-loaded mechanism: the spring-loaded mechanism is disposed on the inner housing 8.

[0018] Specifically, the sealing mechanism can tightly seal the encapsulation process of the voltage regulator. In actual use, during the connection between the top cover 2 and the bottom cover 3 and the outer shell 1, the sealing ring 6 can be deformed by the flat gasket 7 and the flat groove, forming a sealing structure inside the flat groove. The elasticity of the sealing ring 6 is used to fully fill the connection gap after fixing. In addition, the connection between the outer shell 1 and the inner shell 8 is connected by the locking head 9. When the wire harness passes through the locking head 9, a wire harness connection seal is also formed, which improves the overall sealing performance of the voltage regulator.

[0019] The flat gasket 7 and the flat groove have the same width, and the depth of the flat groove is greater than the height of the flat gasket 7. During the compression of the sealing ring 6, the closest distance between the flat gasket 7 and the flat groove is sufficient to support the deformation of the sealing ring 6, and the extended part after deformation can fill the interior of the closest distance to improve the sealing effect.

[0020] Referring to Figures 2 and 3, in a preferred embodiment, the outer walls of the top cover 2 and the bottom cover 3 are provided with equally spaced mounting blocks 4, and the same limiting post 5 is installed between two opposite mounting blocks 4. A nut is connected to the limiting post 5. The outer walls of the outer shell 1 near the top and near the bottom are provided with equally spaced outer holes. The outer walls of the inner shell 8 near the top and near the bottom are provided with equally spaced inner holes. A gap is provided between the inner shell 8 and the outer shell 1, and the lock head 9 is located inside the gap.

[0021] Specifically, by using the set nut in conjunction with the limiting post 5, the top cover 2 and the bottom cover 3 can be pulled close to the outer shell 1, which facilitates the deformation and support of the sealing ring 6 in the sealing mechanism, so as to play a sealing role.

[0022] Referring to Figure 3, in a preferred embodiment, the rebound mechanism includes a mounting groove provided on the inner hole, a return spring 10 provided on the inner wall of the mounting groove, a lock head 9 slidably connected to the inner wall of the inner hole, and one end of the return spring 10 connected to the outer wall of one side of the lock head 9. The side of the lock head 9 away from the inner hole is embedded in the inner wall of the outer hole, and a rubber ring is provided on the outer wall of the lock head 9.

[0023] Specifically, the spring-loaded structure allows the connection between the lock head 9 and the inner hole to be adjusted to an elastic connection, making the installation of the outer shell 1 more convenient during the sealing process. At the same time, the rubber ring on the outside of the lock head 9 can be pressed against the connection with the outer hole under the elastic action, forming a secondary auxiliary seal.

[0024] It should be noted that the lock head 9 set here has a structure similar to a wire connector, which can ensure stable wiring while facilitating sealing through an adapter.

[0025] Working principle: When the voltage regulator is packaged, the limiting post 5 and the nut work together to press the top cover 2 and the bottom cover 3 tightly against the outer shell 1. During this process, the sealing ring 6 can be deformed by the flat gasket 7 and the flat groove together, forming a sealing structure inside the flat groove. The elasticity of the sealing ring 6 is used to fully fill the connection gap after fixing. In addition, the connection between the outer shell 1 and the inner shell 8 is connected by the locking head 9. When the wire harness passes through the locking head 9, a wire harness connection seal is also formed, ensuring a double sealing effect during the packaging and connection processes.

[0026] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
