Description

Technical Field

[0001] This utility model relates to the field of automation technology, specifically to a protective mechanism for industrial instruments. Background Technology

[0002] An automated instrument is an automated technology tool composed of several automated components and possessing relatively complete functions. It generally has several functions at the same time, such as measurement, display, recording, or measurement, control, and alarm. An automated instrument is a system in itself, and also a subsystem in the entire automation system. An automated instrument is an "information machine" and is frequently used in many fields.

[0003] Chinese invention patent CN110987046A discloses a highly protective industrial automation instrument, including a protective box one, a second protective box inside the first protective box, and an instrument body inside the second protective box. A display screen is located on one side of the instrument body. This invention provides dual protection for the instrument body through the design of the first and second protective boxes, effectively preventing dust from affecting the instrument body and extending its service life. However, traditional protective boxes lack efficient connection for maintenance and disassembly, and are not convenient to use, failing to meet the practical needs of rapid operation. Therefore, this invention proposes a protective mechanism for industrial instruments to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a protective mechanism for industrial instruments to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective mechanism for industrial instruments, comprising: a housing, a sealing door rotatably connected to the front surface of the housing, an observation window on the front surface of the sealing door, and a switch handle on the lower surface of the observation window; symmetrically arranged connecting blocks on the rear surface of the sealing door, with positioning posts fixedly connected to the side walls of the connecting blocks; a telescopic rod rotatably connected to the outer surface of the positioning posts; a mounting bracket between two adjacent telescopic rods, with a mounting baffle fixedly connected to the front surface of the mounting bracket; positioning holes on all four sides of the outer surface of the mounting bracket; symmetrically arranged connecting sliders on the outer surface of the mounting bracket; a sliding rod slidably connected between two adjacent connecting sliders; a return spring sleeved on the outer surface of the sliding rod; and fixing blocks fixedly connected to both ends of the sliding rod, with the fixing blocks fixedly connected to the inner surface of the housing. By fixing the fixing blocks to the inner surface of the housing, a stable connection between the sliding rod and the housing is achieved, allowing the sliding rod to stably bear the weight of the mounting bracket and the instrument, while simultaneously transferring the force to the housing, ensuring the overall structural load-bearing capacity.

[0006] Preferably, the side wall of the telescopic rod is rotatably connected to the mounting bracket, and the position of the mounting bracket and the position of the observation window are parallel. This parallel layout design of the mounting bracket and the observation window allows the observation window to be precisely aligned with the instrument on the mounting bracket, enabling staff to clearly and comprehensively view the instrument data through the observation window, avoiding the impact of viewing angle deviation on the monitoring effect.

[0007] Preferably, the switch handle and the front surface of the sealing door are fixedly connected, and the interior of the positioning hole is connected to the interior of the mounting bracket. This design, where the positioning hole is connected to the interior of the mounting bracket, allows external fasteners to pass through the positioning hole and extend deep into the mounting bracket to connect with the instrument, enhancing the connection depth between the fastener and the instrument, improving the fixing effect, and preventing the instrument from loosening in a vibrating environment.

[0008] Preferably, the telescopic rod is located in the middle of the side wall of the mounting frame, and the connecting slider is located below the telescopic rod. The vertical arrangement of the connecting slider and the telescopic rod optimizes the spatial distribution of the components, making the stress points and support points of the mounting frame reasonably matched, improving the stability of the overall structure, while avoiding mutual interference between components and ensuring the independent and smooth operation of each mechanism.

[0009] Preferably, the return spring is located between the fixed block and the connecting slider, and the number of return springs corresponds to the number of sliders. Each slider is equipped with a corresponding return spring, which allows each sliding structure to receive a balanced return force, ensuring that both sides of the mounting bracket return synchronously, avoiding tilting or jamming of the mounting bracket due to uneven return force, and ensuring consistent return effect.

[0010] Preferably, the sealing door extends into the interior of the enclosure, and the sealing door and the inner surface of the enclosure are rotatably connected. This rotatable connection between the sealing door and the inner surface of the enclosure further enhances the stability of the connection, reduces gap wobbling when the sealing door rotates, improves sealing performance, ensures the protective effect when the enclosure is closed, and makes the rotation process smoother and quieter.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model uses a connecting block and a positioning column to link the telescopic rod, which can drive the mounting bracket to move smoothly out of the housing along the sliding rod. Combined with the positioning holes around the mounting bracket, it facilitates the installation and disassembly of the instrument. The return spring helps the mounting bracket to quickly return to its original position after use, and the mounting baffle ensures protection during the movement of the instrument. The overall structure makes the observation, maintenance and disassembly process of the instrument more efficient and greatly improves the convenience of use. Attached Figure Description

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] The present application will be further described in detail below with reference to all the accompanying drawings.

[0016] Example 1: Reference Figures 1 to 4A protective mechanism for industrial instruments includes: a housing 1, a sealing door 2 rotatably connected to the front surface of the housing 1, which allows the housing 1 to be opened and closed by rotating the sealing door 2 to protect internal components; an observation window 3 on the front surface of the sealing door 2, through which the operating status of the industrial instruments inside the housing 1 can be directly observed; a switch handle 4 on the lower surface of the observation window 3, which allows for convenient control of the rotation of the sealing door 2; symmetrically arranged connecting blocks 5 on the rear surface of the sealing door 2, which provide a stable mounting support for positioning posts 6; positioning posts 6 are fixedly connected to the side walls of the connecting blocks 5, which provide a fulcrum for the rotation of telescopic rods 7 and maintain connection stability; a telescopic rod 7 rotatably connected to the outer surface of the positioning post 6, which can adjust its length with the rotation of the sealing door 2 to link with a mounting frame 8; a mounting frame 8 is provided between two adjacent telescopic rods 7, which supports the industrial instruments and provides a mounting carrier for related components; and the mounting frame 8... A mounting baffle 10 is fixedly connected to the front surface of the mounting frame 8, which provides front protection for the industrial instruments on the mounting frame 8. Positioning holes 9 are provided around the outer surface of the mounting frame 8. The positioning holes 9 can be used with external fasteners to limit and fix the industrial instruments on the mounting frame 8. Connecting sliders 13 are symmetrically provided on the outer surface of the mounting frame 8. The connecting sliders 13 connect the mounting frame 8 and the sliding rod 12 and achieve sliding engagement. A sliding rod 12 is slidably connected between two adjacent connecting sliders 13. The sliding rod 12 provides a guide trajectory for the sliding of the connecting slider 13. A return spring 14 is sleeved on the outer surface of the sliding rod 12. The return spring 14 drives the connecting slider 13 and the mounting frame 8 to return to their original positions through elastic deformation. Fixing blocks 11 are fixedly connected to both ends of the sliding rod 12. The fixing blocks 11 securely install the sliding rod 12 inside the housing 1 to ensure structural stability. The fixing blocks 11 are fixedly connected to the inner surface of the housing 1. The positioning and installation of the sliding rod 12 are achieved through the connection between the fixing blocks 11 and the housing 1.

[0017] Reference Figures 3 to 4The side wall of the telescopic rod 7 is rotatably connected to the mounting bracket 8. This connection allows the telescopic rod 7 to drive the mounting bracket 8 to move smoothly. The position of the mounting bracket 8 is parallel to the position of the observation window 3, ensuring that the status of the industrial instruments on the mounting bracket 8 can be clearly observed through the observation window 3. The switch handle 4 is fixedly connected to the front surface of the sealing door 2. This fixed relationship ensures that the operation of the switch handle 4 can synchronously drive the sealing door 2 to rotate. The interior of the positioning hole 9 is connected to the interior of the mounting bracket 8, allowing external fasteners to pass through the positioning hole 9 and penetrate into the interior of the mounting bracket 8 to fix the industrial instruments. The telescopic rod 7 is located in the middle of the side wall of the mounting bracket 8. This position makes the driving force of the telescopic rod 7 on the mounting bracket 8 more balanced. Block 13 is located below the telescopic rod 7. Through positional cooperation, the connecting slider 13 slides synchronously and smoothly when the telescopic rod 7 moves the mounting bracket 8. The return spring 14 is located between the fixed block 11 and the connecting slider 13. The elastic return function of the connecting slider 13 is achieved by the contact of the two ends. The number of return springs 14 corresponds to the number of slide rods 12, ensuring that the connecting slider 13 on each slide rod 12 can obtain the corresponding return force. The sealing door 2 extends into the interior of the box 1, extending the contact length of the sealing door 2 to improve the sealing and protection effect of the box 1. The sealing door 2 and the inner surface of the box 1 are rotatably connected, further strengthening the connection stability and rotation smoothness of the sealing door 2 and the box 1.
