Description

Technical Field

[0001] This utility model relates to the field of industrial instrumentation technology, specifically to an instrument housing structure and an industrial instrument. Background Technology

[0002] Industrial instruments, as key equipment in industrial production and process control, are widely used for monitoring and displaying physical quantities such as pressure, flow, temperature, and liquid level. Their reliability is directly related to the safe, stable, and efficient operation of the production system.

[0003] In the existing technology, the housings of industrial instruments commonly found on the market mostly adopt a basic structure of front and rear shells that fit together, relying on screws for connection and fixation. Screw fastening is a simple and low-cost method.

[0004] However, traditional instrument housing structures are prone to loosening under continuous mechanical vibration, and the locking reliability is insufficient, posing safety hazards. Therefore, this utility model proposes an instrument housing structure and an industrial instrument to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an instrument housing structure and an industrial instrument to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a front housing and a rear housing that cooperate with the instrument. The left side of the front housing is connected to the rear housing via a hinge. A slot is provided on the right side of the outer surface of the front housing. A bottom end with a spring is fixed to the bottom of the inner surface of the slot. A card plate is fixedly connected to the top of the spring. A base is provided on the right side of the outer surface of the rear housing. One end of a buckle is rotatably connected inside the base. The other end of the buckle is engaged between the top of the inner surface of the slot and the card plate.

[0007] Preferably, a limiting groove is formed at the top of the inner surface of the card slot, and the limiting groove is semi-circular.

[0008] Preferably, a limiting block is provided on the surface of the buckle near the slot, and the limiting block cooperates with the limiting slot.

[0009] Preferably, the front surface of the rear outer shell is provided with a slot, the rear surface of the front outer shell is provided with a plug that mates with the slot, and a sealing ring is provided between the front and rear outer shells.

[0010] Preferably, the bottom edges of the front and rear outer shells are provided with notches, and the merging of the notches of the front and rear outer shells forms a through hole.

[0011] Preferably, the inner surface of the rear outer shell is provided with a plurality of buffer pads, and the surface of the front outer shell is provided with a protective mirror.

[0012] An industrial instrument, including the aforementioned instrument housing structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The instrument housing structure and industrial instrument proposed in this utility model, through a double locking system consisting of a spring, a retaining plate, a limiting block and a limiting groove, ensures that the locking force is stable and can compensate for tolerances by the continuous elastic pressing force provided by the spring and the retaining plate. The ball and socket fit between the limiting block and the limiting groove mechanically prevents the buckle from opening under vibration and impact. The two work together to achieve automatic compensation of locking force and ultra-high reliability in vibration environment, solving the technical pain point of traditional buckles being easy to loosen due to vibration or tolerance. 2. The instrument housing structure and industrial instrument proposed in this utility model effectively isolate and attenuate the vibration energy transmitted to the instrument by setting a buffer pad on the inner surface of the rear housing. This solves the reliability problem of loose solder joints of internal components and fatigue failure of components caused by continuous vibration, and significantly improves the long-term working stability of the instrument in the vibration environment. 3. The instrument housing structure and industrial instrument proposed in this utility model achieve rapid and accurate alignment and closure of the housing through a guiding and closing mechanism composed of hinges, inserts, and slots, while ensuring structural integrity. In the initial stage of closure, the cooperation of the inserts and slots performs coarse positioning and stress distribution, effectively solving the problem of excessive torque on the hinges and locking mechanisms due to structural misalignment, which affects the long-term service life.

[0019] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0020] Example 1: Please refer to Figures 1 to 3This utility model provides a technical solution: an industrial instrument, including the aforementioned instrument housing structure, a front housing 1 and a rear housing 2 that cooperate with the instrument. The left side of the front housing 1 is connected to the rear housing 2 via a hinge 3. A slot 4 is provided on the right side of the outer surface of the front housing 1. The bottom end of a spring 5 is fixed to the bottom of the inner surface of the slot 4. A locking plate 6 is fixedly connected to the top of the spring 5. A base 7 is provided on the right side of the outer surface of the rear housing 2. One end of a buckle 8 is rotatably connected inside the base 7. The other end of the buckle 8 is engaged between the top of the inner surface of the slot 4 and the locking plate 6. The continuous elastic force of the spring 5 is converted into a pressing force on the buckle 8 through the locking plate 6 to achieve locking. A limiting groove 9 is provided on the top of the inner surface of the slot 4. The limiting groove 9 is semi-circular. A limiting block 10 is provided on the surface of the buckle 8 near the slot 4. The limiting block 10 cooperates with the limiting groove 9 to effectively prevent the buckle 8 from opening when facing continuous mechanical vibration. A slot 11 is provided on the surface of the rear shell 2. A plug 12 that cooperates with the slot 11 is provided on the rear surface of the front shell 1 for coarse positioning and stress sharing. A sealing ring 13 is provided between the front shell 1 and the rear shell 2.

[0021] First, the instrument body is placed into the matching rear outer shell 2, and the front outer shell 1 is closed to the rear outer shell 2 via hinge 3. As the front outer shell 1 is about to be fully closed, the surface insert 12 is inserted at a certain angle into the slot 11 at the top of the rear outer shell 2. The insert 12 and slot 11 mechanism achieves coarse positioning of the shell and distributes stress, effectively preventing excessive torque on the hinge 3 and subsequent latching mechanism due to structural misalignment, ensuring the structural integrity for long-term use. At this time, the sealing ring 13 is compressed between the mating surfaces of the front outer shell 1 and the rear outer shell 2, serving as a sealing component to prevent dust and moisture, ensuring the safety of the internal instrument core components.

[0022] Then, the buckle 8 is rotated around the pivot on the base 7. When no force is applied, the locking plate 6 is at the top of the slot 4 under the preload of the spring 5. When force is applied to press down the buckle 8, the locking plate 6 moves downward against the elastic force of the spring 5. The buckle 8 continues to press down until a "click" is heard. At this time, the limiting block 10 falls into the limiting groove 9, thus ensuring that the buckle 8 is in place. The ball and socket cooperation between the limiting block 10 and the limiting groove 9 can effectively prevent the buckle 8 from opening under continuous mechanical vibration. After the buckle 8 is in place, the continuous elastic force of the spring 5 is converted into a pressing force on the buckle 8 through the locking plate 6 to achieve locking. The spring 5 can compensate for the manufacturing tolerance of the parts to ensure that the locking force always exists. Together with the limiting block 10 and the limiting groove 9, it forms a double locking system, further preventing the buckle 8 from loosening due to vibration, making the entire locking mechanism more reliable.

[0023] Example 2: Based on Example 1, please refer to [link / reference]. Figures 4 to 6The bottom edges of the front housing 1 and the rear housing 2 are provided with notches. The merging of the notches of the front housing 1 and the rear housing 2 forms a through hole 14. The inner surface of the rear housing 2 is provided with several buffer pads 15. The surface of the front housing 1 is provided with a protective mirror 16, which can effectively isolate and attenuate the vibration transmitted to the instrument and ensure that the instrument can work stably. When the semi-circular notches on the front housing 1 and the rear housing 2 are closed, a circular through hole 14 is formed at the bottom of the instrument housing. The diameter of the through hole 14 matches the connecting rod at the bottom of the instrument, ensuring that the instrument connection equipment is not affected. The buffer pad 15 provided on the inner surface of the rear housing 2 can effectively isolate and attenuate the vibration transmitted to the instrument in a continuous vibration environment, preventing component solder joints from loosening and component fatigue failure. The protective mirror 16 provided on the surface of the front housing 1 provides a clear view for reading the display data of the internal instruments.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
