Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical instrumentation technology, specifically to an electrical instrument housing that is easy to assemble and fix. Background Technology
[0002] Electrical instruments are classified into analog indicating instruments, digital instruments, recording instruments, calculating instruments, and comparating instruments according to their structural characteristics. These instruments can be mounted on panels, cabinets, or boxes, or they can be portable. Indicating instruments are pointer-type instruments, such as speedometers and tachometers in automobiles. Digital instruments refer to instruments that display information using LED digital displays. The casing of electrical instruments is an important component of electrical measuring instruments, mainly used to fix and protect the internal measuring mechanisms, measuring circuits, and other components.
[0003] Common electrical instrument housings consist of two parts: a panel and a housing. During assembly, the panel is snapped onto the front of the housing, ensuring that the screw holes inside the panel correspond one-to-one with the screw holes inside the housing, and then the connection is made using screws.
[0004] However, this method requires tools to disassemble and assemble multiple sets of screws during the assembly of the outer casing, making the entire assembly process time-consuming and labor-intensive. Furthermore, after unscrewing the screws, the panel still needs to be pried off due to the snap-fit structure between the casing and the panel. This is not only inconvenient to operate, but also prone to causing the panel or snap-fit to break during prying. It cannot meet the working requirements of electrical instruments. Therefore, an electrical instrument casing that is easy to assemble and fix is proposed. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an electrical instrument housing that is easy to assemble and fix, thereby solving the technical problem that not only do tools need to be used to disassemble and assemble multiple sets of screws during housing assembly, but the entire assembly process is also time-consuming and labor-intensive.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrical instrument housing that is easy to assemble and fix, comprising:
[0007] The housing has a panel mounted on its mounting surface, a socket is mounted on the outside of the housing, and a side plate is connected to the outside of the panel at a position corresponding to the socket.
[0008] The clip is inserted into the socket via a bearing. A plug is connected to the back of the side plate. An assembly groove is provided on the contact surface of the clip. A spring is inserted into the center of the socket cavity.
[0009] A ball head is installed on the outer end of the spring. Assembly frames are installed on the upper and lower parts of the housing. Mounting blocks are installed on the upper and lower sides of the panel at positions corresponding to the assembly frames. A rotating shaft is inserted into the mounting block through a bearing. A locking plate is connected to the tail end of the rotating shaft.
[0010] Preferably, the ends of the plugs are all round, and the shape of the mounting groove is adapted to the shape of the plug, which improves the tightness of the engagement between the clip and the plug.
[0011] Preferably, the back of the ball head is coaxially connected to a plug shaft, which passes through the interior of the spring, thereby improving the stability of the ball head during movement and preventing twisting.
[0012] Preferably, each of the rotating shafts has a knob coaxially mounted on its front end, and each knob has a paddle mounted on its outside, making it easier to rotate the rotating shaft.
[0013] Preferably, the length of the locking plate is the same as the diagonal length of the assembly frame, and the outer ends of the locking plates are all arc-shaped, so that the locking plates can be inserted into the interior of the assembly frame when tilted, and cannot pass through the assembly frame when horizontal, thereby enabling assembly positioning.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This easy-to-assemble and secure electrical instrument housing allows the plug to be inserted into the locking head and pressed against its inner end by aligning the panel with the front of the housing. This allows the plug to be held in place by the locking head. Rotating the pivot then allows the locking plate to be horizontal, thus completing the panel assembly. This improves the speed and convenience of assembling and securing the electrical instrument housing. For disassembly, simply rotating the pivot tilts the locking plate, causing the spring to spring back and push the locking head to tilt, allowing the plug to be pushed out. The panel can then be picked up directly without further prying, improving the quality of assembling and disassembling the electrical instrument housing. Attached Figure Description

[0024] 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.
[0025] This utility model provides a technical solution: an electrical instrument housing that is easy to assemble and fix, including a housing 1, a panel 2, a socket 3, a side plate 4, a clip 5, a plug 6, an assembly groove 7, a spring 8, a ball head 9, a shaft 10, an assembly frame 11, a mounting block 12, a rotating shaft 13, a knob 14, and a locking plate 15.
[0026] Please see Figure 1 A panel 2 is installed on the mounting surface of the housing 1, a socket 3 is installed on the outside of the housing 1, and a side plate 4 is connected to the outside of the panel 2 at the position corresponding to the socket 3.
[0027] Please see Figure 2 The clip 5 is inserted into the socket 3 via a bearing, and the plug 6 is connected to the back of the side plate 4. Please refer to [link / reference]. Figure 3 The contact surface of the card head 5 is provided with an assembly groove 7, and a spring 8 is inserted into the middle of the inner cavity of the socket 3;
[0028] Ball head 9 is mounted on the outer end of spring 8. Please refer to [link / reference]. Figure 4 Assembly frames 11 are installed on both the upper and lower parts of the housing 1. Please refer to [link / reference]. Figure 5 Mounting blocks 12 are installed on both the upper and lower sides of panel 2, corresponding to the positions of the assembly frame 11. A rotating shaft 13 is inserted into the interior of each mounting block 12 via bearings. (See also...) Figure 6Each end of the rotating shaft 13 is connected to a locking plate 15. By aligning the panel 2 with the front of the housing 1, the plug 6 can be inserted into the inside of the latch 5 and the inner end of the latch 5 can be pressed, allowing the latch 5 to hold the plug 6 tightly. Rotating the rotating shaft 13 then makes the locking plate 15 horizontal, thus completing the assembly of the panel 2. This improves the speed and convenience of assembling and fixing the electrical instrument housing. For disassembly, simply rotating the rotating shaft 13 tilts the locking plate 15. At this time, the spring 8 loses its limit and springs up, causing the ball head 9 to push the latch 5 tilt, allowing the plug 6 to be pushed out. The panel 2 can then be picked up directly without further prying, improving the quality of disassembly and assembly of the electrical instrument housing. Please refer to [link / reference]. Figure 2 The ends of plugs 6 are all round, and the shape of the mounting groove 7 matches the shape of plugs 6. Please refer to [link / reference]. Figure 3 The ball head 9 is coaxially connected to the back of the insert shaft 10, which passes through the interior of the spring 8. Please refer to [link / reference]. Figure 5 Each of the rotating shafts 13 has a knob 14 coaxially mounted on its front end, and each knob 14 has a paddle mounted on its exterior. Please refer to [link / reference]. Figure 7 The length of the locking plate 15 is the same as the diagonal length of the assembly frame 11, and the outer ends of the locking plate 15 are all arc-shaped.
[0029] This solution connects panel 2 to the front of housing 1, allowing plug 6 to be inserted into the inside of clip 5 and press the inner end of clip 5. This allows clip 5 to hold plug 6 tightly. Then, rotating shaft 13 makes locking plate 15 horizontal, thus completing the assembly of panel 2. This improves the speed and convenience of assembling and fixing electrical instrument housings. When disassembling, simply rotating shaft 13 makes locking plate 15 tilted. At this time, spring 8 loses its limit and springs up, causing ball head 9 to push clip 5 tilted, thus pushing plug 6 out. Panel 2 can then be picked up directly without prying panel 2, improving the quality of disassembly and assembly of electrical instrument housings.
