Description

Technical Field

[0001] This utility model relates to the field of converter housings, specifically a high-strength converter housing. Background Technology

[0002] A converter is a device or circuit that converts electrical energy, signals, or data from one form to another. It is widely used in power electronics, communications, computers, and other fields. Depending on their functions, converters can be divided into various types. The converter housing protects the electronic components inside the converter from damage caused by compression.

[0003] Existing converter housings are assembled by bolting the housing to the upper and lower covers. However, bolting is a cumbersome method, requiring tools to assemble multiple bolts to complete the assembly of the upper and lower covers. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a high-strength converter housing to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength converter housing, comprising a housing, an upper cover, and a lower cover, wherein the housing, the upper cover, and the lower cover constitute the converter housing. The upper cover and the lower cover are movably mounted on both ends of the housing, and multiple sets of locking blocks are fixed to the bottom of both the upper cover and the lower cover. The cross-section of the locking blocks is L-shaped. Rotating grooves are provided at both ends of the housing, and a limiting groove is provided on one side of the bottom end of the inner wall of the rotating groove. Sealing grooves are provided at both ends of the housing, and sealing rings are installed inside the sealing grooves. A limiting component is installed at the bottom end of the inner wall of the rotating groove. The housing, the upper cover, and the lower cover are all made of aluminum alloy. An installation groove is provided inside the lower cover, and the inner diameter of the installation groove is the same as the inner diameter of the fixing ring.

[0006] By adopting the above technical solution, the problem of cumbersome assembly of existing converter housings is solved. During assembly, the sealing ring is installed inside the sealing groove. When the upper and lower covers are installed, the locking block enters the interior of the rotating groove, and the upper and lower covers squeeze the sealing ring. Then, the upper and lower covers are rotated, so that the end of the locking block enters the inner wall of the limiting groove, thereby completing the installation of the upper and lower covers. This replaces the traditional bolt fixing method and improves the installation efficiency. The upper and lower covers squeeze the sealing ring, and the sealing ring provides an elastic force to the upper and lower covers, so that the upper and lower covers will not easily shake. At the same time, the sealing ring can effectively prevent dust, moisture and other impurities from entering the converter housing, further ensuring the stability and service life of the product.

[0007] The present invention is further configured such that the limiting component includes a protrusion movably installed on the inner wall of the rotating groove, and a spring is fixed at the bottom of the protrusion; a moving groove is provided at the bottom end of the inner wall of the rotating groove, and the inner wall of the moving groove is in contact with the outer wall of the protrusion; a groove is provided at the bottom of the locking block; and the end of the protrusion is arc-shaped.

[0008] Preferably, when the locking block rotates, it will squeeze the protrusion, and the protrusion will slide on the inner wall of the moving groove. While the protrusion is sliding, it will squeeze the spring. When the locking block rotates to the position, the spring will drive the protrusion to reset and enter the interior of the groove, further limiting the locking block and increasing the friction between the locking block and the spring.

[0009] The present invention is further provided that a transparent lens is provided in the middle of the upper cover, and the transparent lens is made of tempered glass.

[0010] As a preferred option, transparent lenses not only offer high clarity but are also scratch-resistant and durable, effectively protecting the internal display content.

[0011] The present invention is further configured such that the inner wall of the rotating groove is inclined, and the bottom of the card block is inclined.

[0012] Preferably, the inclined surface at the bottom of the card block and the inclined surface on the inner wall of the rotating groove enable the upper and lower covers to better install the card block into the interior of the rotating groove during installation.

[0013] The present invention is further provided that a fixing ring is fixed to the inner wall of the sealing groove.

[0014] Preferably, the sealing ring is positioned by a fixed ring, so that the sealing ring is fitted onto the outer wall of the fixed ring.

[0015] The present invention is further provided that the bottom of the upper cover is provided with a slot, and the inner wall of the slot is fixed with a protruding ring.

[0016] Preferably, the slot can engage with the outer wall of the sealing ring, and the protrusion can engage with the inner wall of the sealing ring, thereby achieving the purpose of sealing the top cover.

[0017] In summary, the present invention has the following main advantages:

[0018] 1. This utility model solves the problem of cumbersome assembly of existing converter housings by setting up a shell, upper cover, lower cover, locking block, rotating groove, and limiting groove. During assembly, the sealing ring is installed inside the sealing groove. When installing the upper and lower covers, the locking block enters the rotating groove, and the upper and lower covers squeeze the sealing ring. Then, the upper and lower covers are rotated, so that the end of the locking block enters the inner wall of the limiting groove, thereby completing the installation of the upper and lower covers. This replaces the traditional bolt fixing method and improves the installation efficiency. The upper and lower covers squeeze the sealing ring, and the sealing ring gives the upper and lower covers an elastic force, so that the upper and lower covers will not easily shake. At the same time, the sealing ring can effectively prevent dust, moisture and other impurities from entering the converter housing, further ensuring the stability and service life of the product.

[0019] 2. This utility model, by setting a limiting component, will squeeze the protrusion when the locking block rotates. The protrusion slides on the inner wall of the moving groove. While the protrusion slides, it will squeeze the spring. When the locking block rotates to the position, the spring will drive the protrusion to reset. The protrusion enters the interior of the groove, further limiting the locking block and increasing the friction between the locking block and the spring. Attached Figure Description

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] First embodiment:

[0033] Please see Figures 1-6 The converter housing consists of a housing 1, an upper cover 2, and a lower cover 3. The housing 1, upper cover 2, and lower cover 3 form the converter housing. The converter housing is assembled in three sections, which facilitates disassembly and maintenance and reduces downtime for repairs. The upper cover 2 and lower cover 3 are movably installed at both ends of the housing 1, and multiple sets of locking blocks 5 are fixed at the bottom of the upper cover 2 and lower cover 3. The cross-section of the locking blocks 5 is L-shaped. Rotating grooves 8 are opened at both ends of the housing 1, and a limiting groove 81 is opened on one side of the bottom of the inner wall of the rotating groove 8. Sealing grooves 11 are opened at both ends of the housing 1, and sealing rings 10 are installed inside the sealing grooves 11. A limiting component is installed at the bottom of the inner wall of the rotating groove 8. The housing 1, upper cover 2, and lower cover 3 are all made of aluminum alloy. The lower cover 3 has an installation groove 7 inside, and the inner diameter of the installation groove 7 is the same as the inner diameter of the fixing ring 12.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The top cover 2 has a transparent lens 4 in the middle, and the transparent lens 4 is made of tempered glass. The transparent lens 4 not only has high clarity, but is also scratch-resistant and wear-resistant, which can effectively protect the internal display content.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 , Figure 5 and Figure 6 The inner wall of the rotating groove 8 is sloped, and the bottom of the locking block 5 is sloped. The sloped bottom of the locking block 5 and the sloped inner wall of the rotating groove 8 enable the upper cover 2 and the lower cover 3 to better install the locking block 5 into the interior of the rotating groove 8 during installation.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 A fixing ring 12 is fixed to the inner wall of the sealing groove 11. The fixing ring 12 can limit the sealing ring 10 so that the sealing ring 10 is fitted onto the outer wall of the fixing ring 12.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 5The bottom of the upper cover 2 is provided with a slot 6, and the inner wall of the slot 6 is fixed with a protruding ring 61. The slot 6 can be engaged with the outer wall of the sealing ring 10, and the protruding ring 61 can be engaged with the inner wall of the sealing ring 10, thereby achieving the purpose of sealing the upper cover 2.

[0038] Second embodiment:

[0039] Please see Figure 3 , Figure 7 and Figure 8 The limiting component includes a protrusion 9 movably mounted on the inner wall of the rotating groove 8, and a spring 91 fixed at the bottom of the protrusion 9. A moving groove 82 is provided at the bottom end of the inner wall of the rotating groove 8, and the inner wall of the moving groove 82 fits against the outer wall of the protrusion 9. A groove 51 is provided at the bottom of the locking block 5. The end of the protrusion 9 is arc-shaped. When the locking block 5 rotates, one side of the bottom inclined surface will contact the protrusion 9, thereby squeezing the protrusion 9. The protrusion 9 slides on the inner wall of the moving groove 82. When the protrusion 9 slides, it will squeeze the spring 91. When the locking block 5 rotates to one side of the inner wall of the limiting groove 81, the spring 91 drives the protrusion 9 to reset. The protrusion 9 enters the interior of the groove 51. At this time, the spring 91 is in a squeezed state. The protrusion 9 further applies pressure to the locking block 5, increasing the friction between the locking block 5 and the housing 1.

[0040] In practical operation, the present invention is as follows: During assembly, the sealing ring 10 is installed inside the slot 6, with the sealing ring 10 slightly higher than the top of the housing 1. Then, the upper cover 2 is installed, and the locking block 5 at the bottom of the upper cover 2 enters the rotating groove 8. Because both the inner wall of the rotating groove 8 and the bottom of the locking block 5 are sloped, the locking block 5 can better enter the rotating groove 8. Then, the upper cover 2 is pressed down, and the slot 6 at the bottom of the upper cover 2 contacts the top of the sealing ring 10. Pressing the upper cover 2 down further compresses the sealing ring 10. Rotating the upper cover 2 causes the locking block 5 to rotate. One side of the bottom slope will contact the protrusion 9, thereby squeezing the protrusion 9. The protrusion 9 slides on the inner wall of the moving groove 82. When the protrusion 9 slides, it will squeeze the spring 91. When the locking block 5 rotates to one side of the inner wall of the limiting groove 81, the spring 91 drives the protrusion 9 to reset. The protrusion 9 enters the interior of the groove 51. At this time, the spring 91 is in a squeezed state. The protrusion 9 further applies pressure to the locking block 5, increasing the friction between the locking block 5 and the housing 1. The locking block 5 is limited by the limiting groove 81. The sealing ring 10 gives the upper cover 2 an elastic force, so that the upper cover 2 will not easily separate from the housing 1.

[0041] Then install the lower cover 3, and install the sealing ring 10 inside the slot 6. Then install the lower cover 3 according to the installation steps of the upper cover 2 described above.
