Description

Technical Field

[0001] The utility model belongs to the technical field of parameter instruments, and particularly relates to a shell structure of a parameter instrument. Background Art

[0002] A parameter instrument is a device or equipment used to detect, measure, observe, and calculate various physical quantities, material components, physical property parameters, etc. Most of the currently used shells of parameter instruments are composed of a housing for loading various modules and a sealed protective cover;

[0003] When assembling the shell of a parameter instrument nowadays, most of them directly use screws to sequentially pass through the threaded holes at the corners of the protective cover and the housing and tighten and fix them. Such a combined installation method of directly screwing the screws into the threaded holes opened on the housing for fixation is rather cumbersome and inconvenient, and it is not convenient to disassemble the two subsequently, thus making it difficult to maintain the components inside the housing / on the protective cover, and the practicability is not good;

[0004] Therefore, it is necessary to propose a shell structure of a parameter instrument to effectively solve the above problems. Summary of the Utility Model

[0005] To solve the above problems existing in the prior art, the utility model provides a shell structure of a parameter instrument, which has the characteristics of being convenient for quickly installing and disassembling the shell of the parameter instrument and its protective cover.

[0006] To achieve the above object, the utility model provides the following technical solution: A shell structure of a parameter instrument, including a parameter instrument housing, a parameter instrument housing connection plate is integrally formed on one side of the parameter instrument housing, a parameter instrument protective cover is arranged outside the parameter instrument housing connection plate, a frame-shaped connection block is fixed on the surface of the parameter instrument housing connection plate close to the parameter instrument protective cover, springs are inlaid at the four corner positions of the frame-shaped connection block, docking grooves are opened on the parameter instrument protective cover at positions corresponding to the frame-shaped connection block and the springs, and U-shaped rotating rods are rotatably connected to both sides of the parameter instrument housing connection plate, and the long vertical rod parts of the U-shaped rotating rods lean against the side positions on the surface of the parameter instrument protective cover.

[0007] As a preferred technical solution of the shell structure of a parameter instrument of the utility model, one end of the frame-shaped connection block facing away from the parameter instrument housing connection plate is clamped into the docking groove, and one end of the spring facing away from the frame-shaped connection block is not fixedly connected to the parameter instrument protective cover.

[0008] As a preferred technical solution of the shell structure of a parameter instrument of the utility model, the spring is a metal component.

[0009] As a preferred technical solution for the shell structure of a parameter meter of the utility model, two positioning blocks are vertically symmetrically adhered to the inner wall surface of the parameter meter protective cover, and positioning slots are opened on the parameter meter protective cover at positions corresponding to the positioning blocks.

[0010] As a preferred technical solution for the shell structure of a parameter meter of the utility model, the size of the positioning card block is adapted to the size of the interior of the positioning card slot.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: when the present invention is in use, the parameter instrument protective cover is springy outwards by the penetration of the frame-shaped connecting block provided on the parameter instrument shell connecting plate on one side of the parameter instrument shell in the docking groove in the parameter instrument protective cover, and the parameter instrument protective cover is squeezed on one side of the frame-shaped connecting block by the parameter instrument protective cover, and the parameter instrument protective cover is pressed tightly by the U-shaped rotating rod parts on both sides of the parameter instrument protective cover, and further combined with the clamping setting of the positioning card blocks on the U-shaped rotating rod at the corresponding positioning card grooves, the parameter instrument protective cover can be stably connected to one side of the parameter instrument shell connecting plate; at the same time, subsequently, only part of the parameter instrument protective cover is pressed by the internal pressure, and then the U-shaped rotating rod is flipped outward, so that part of the parameter instrument protective cover can be directly removed to one side, and the parameter instrument protective cover is completely removed. The parameter meter housing and its protective cover are operated separately in pairs, and when resetting and installing, the parameter meter protective cover is covered on one side of the parameter meter housing connecting plate on the parameter meter housing, and then the U-shaped rotating rod is flipped and reset, so that the parameter meter housing and its protective cover can be quickly installed, which is also conducive to convenient maintenance and processing of components in the housing / on the protective cover. The structure is simple and easy to operate by personnel, which solves the problem that when assembling the outer shell of the parameter meter, most of the screws are directly used to pass through the threaded holes at the corners of the protective cover and the housing in turn to tighten and fix them. This combined installation method of directly screwing the screws into the threaded holes opened on the housing for fixing is relatively cumbersome and inconvenient, and it is inconvenient to disassemble the two later, and then maintain and process the components in the housing / on the protective cover, which is not practical.

[0020] Embodiment

[0021] Please refer to Figure 1-5 , the present utility model provides the following technical solutions: An outer shell structure of a parameter instrument, including a parameter instrument housing 1, a parameter instrument housing connection plate 2 integrally formed on one side of the parameter instrument housing 1, and a parameter instrument protective cover 3 arranged on the outer side of the parameter instrument housing connection plate 2. The combination of the above three can be used for normal parameter instruments, which is an existing technical means and will not be elaborated too much;

[0022] A frame-shaped connection block 4 is fixed on the surface of the parameter instrument housing connection plate 2 close to the parameter instrument protective cover 3. Springs 7 (the springs 7 are metal components, which are beneficial for long-term use) are inlaid at the four corner positions of the frame-shaped connection block 4. Docking grooves 6 are opened at the positions of the parameter instrument protective cover 3 corresponding to the frame-shaped connection block 4 and the springs 7 (one end of the frame-shaped connection block 4 away from the parameter instrument housing connection plate 2 is stuck into the docking groove 6, and one end of the spring 7 away from the frame-shaped connection block 4 is not fixedly connected to the parameter instrument protective cover 3, that is, only in contact but not connected). Among them, U-shaped rotating rods 5 are rotatably connected to both sides of the parameter instrument housing connection plate 2 (specifically, please refer to Figure 1 ), and the long vertical rod part of the U-shaped rotating rod 5 is placed on the side position on the surface of the parameter instrument protective cover 3. In this implementation scheme:

[0023] On the inner side wall surface of the parameter instrument protective cover 3, two positioning blocks 8 are vertically and symmetrically adhered. At the position corresponding to the positioning blocks 8 on the parameter instrument protective cover 3, positioning slots 9 are provided (the size of the positioning blocks 8 is adapted to the size inside the positioning slots 9, and the positioning blocks 8 are inserted into the corresponding positioning slots 9). Through the penetration of the frame-shaped connecting block 4 provided on the parameter instrument housing connecting plate 2 on one side of the parameter instrument housing 1 into the docking groove 6 in the parameter instrument protective cover 3, combined with the extrusion effect of the parameter instrument protective cover 3 on one side of the frame-shaped connecting block 4, the parameter instrument protective cover 3 springs out under the action of the spring 7, and the U-shaped rotating rods 5 on both sides of the parameter instrument protective cover 3 press tightly on the parameter instrument protective cover 3. Further combined with the clamping setting of the positioning blocks 8 on the U-shaped rotating rods 5 at the corresponding positioning slots 9, the parameter instrument protective cover 3 can be stably connected to one side of the parameter instrument housing connecting plate 2;

[0024] By pressing a part of the parameter instrument protective cover 3 inward and then flipping the U-shaped rotating rod 5 outward, a part of the parameter instrument protective cover 3 can be directly taken to one side, completing the disassembly operation of the parameter instrument housing 1 and its protective cover. And during the reset installation, cover the parameter instrument protective cover 3 on one side of the parameter instrument housing connecting plate 2 of the parameter instrument housing 1, and then flip the U-shaped rotating rod 5 back to its original position, and the rapid installation of the parameter instrument housing 1 and its protective cover can be completed, which is also beneficial for the convenient maintenance of the components inside the housing / on the protective cover. The structure is simple and convenient for personnel to operate.

[0025] The working principle and usage process of the present utility model: During the use of the present utility model, when assembling the parameter instrument housing 1 and the parameter instrument protective cover 3, align the docking groove 6 on the parameter instrument protective cover 3 with the frame-shaped connecting block 4 on the parameter instrument housing connecting plate 2, and then press the parameter instrument protective cover 3 towards one side of the parameter instrument housing 1. A part of the spring 7 deforms, and at the same time, flip the U-shaped rotating rods 5 on both sides, so that the long rod parts of the U-shaped rotating rods 5 flip to the surface side of the parameter instrument protective cover 3, making the positioning blocks 8 inside the U-shaped rotating rods 5 align with the positioning slots 9 on the parameter instrument protective cover 3. Then release the pressure on the parameter instrument protective cover 3, and a part of the deformation of the spring 7 resets, causing the positioning blocks 8 to be inserted into the corresponding positioning slots 9, and cooperating with the U-shaped rotating rods 5 to quickly and tightly connect the parameter instrument housing connecting plate 2 and the parameter instrument protective cover 3 together, enabling the parameter instrument housing 1 and the parameter instrument protective cover 3 to be quickly installed and used;

[0026] When it is necessary to disassemble the parameter meter housing 1 and the parameter meter protective cover 3, the parameter meter protective cover 3 is pressed toward one side of the parameter meter housing 1, and the parameter meter protective cover 3 moves toward the parameter meter housing 1. The spring 7 is deformed, and the positioning block 8 is disengaged from the corresponding positioning slot 9. Then, the U-shaped rotating rod 5 is rotated to both sides to pull the parameter meter protective cover 3 out to one side, thereby completing the disassembly of the parameter meter housing 1 and the parameter meter protective cover 3. The structure is simple and convenient for personnel to operate.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
