Description

Technical Field

[0001] This utility model relates to the field of detectors, and in particular to a fixed gas detector with a concentration display function. Background Technology

[0002] A gas detector is a safety device used to detect the concentration of specific gases in the environment. It is widely used in industries, mining, environmental protection, and homes. A stationary gas detector is a monitoring device that is installed at the work site for a long time. It can detect and display the concentration of specific gases in the environment in real time, effectively prevent gas leak accidents, and is a key tool to protect life and property.

[0003] Traditional fixed gas detectors can only detect gas concentration in one direction. When the gas flow direction is the same as the detection direction of the device, it is easy to cause errors in the detection results, which may affect the personal safety of the staff. Secondly, traditional fixed gas detectors require disassembly of the entire device for maintenance, which is a relatively cumbersome process. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fixed gas detector with concentration display function. The device can be driven to move up or down by a toothed plate on a fixed column in conjunction with a first motor, a worm gear, and a worm wheel, allowing the device to detect a wider range. Furthermore, the device can be steered by a second motor in conjunction with gears and a fixed plate. This mechanism can effectively expand the detection range of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

The quick-fixing mechanism includes a fixing plate fixedly connected to the outer wall of the internal gear ring, a snap-fit ​​seat fixedly connected to the front end of the upper surface of the fixing plate, sliding buttons slidably connected to the outer walls of both sides of the snap-fit ​​seat, a snap-fit ​​bracket fixedly connected to the side of the sliding button near the middle, a spring fixedly connected to the outer wall of the rear end of the snap-fit ​​bracket, and a snap-fit ​​post fixedly connected to one side of the outer wall of the front end of the snap-fit ​​bracket.

[0008] Through the above technical solution, the device can be driven to move up or down by the toothed plate on the fixed column in conjunction with the first motor, worm gear and worm wheel, which can enable the device to detect a wider range. Furthermore, the device can be steered by the second motor in conjunction with the gear and fixed plate. This mechanism can effectively expand the detection range of the device.

[0009] Furthermore, the front outer wall of the snap-fit ​​seat has two sliding grooves, the rear end of the outer wall of the snap-fit ​​bracket is fixedly connected to a limiting plate, the end of the spring away from the snap-fit ​​bracket is fixedly connected to the snap-fit ​​seat, the rear end of the upper surface of the fixing plate is fixedly connected to a shell, the upper surface of the snap-fit ​​seat has a snap-fit ​​groove, and the inner wall of the snap-fit ​​groove is provided with a protective cover.

[0010] The above technical solution allows the sliding button to drive the clamping frame to compress the spring, while the clamping frame pulls the clamping post to disengage from the display detector. This enables quick replacement or maintenance of the display detector, effectively improving the maintenance efficiency of the staff. Furthermore, the combination of the second motor and the first motor makes maintenance even more convenient.

[0011] Furthermore, a display detector is provided on the inner bottom surface of the card holder, and sliding frames are fixedly connected to both sides of the outer wall of the rear end of the display detector, and the sliding frames are slidably connected to the slide groove;

[0013] Furthermore, a fixing sleeve is fixedly connected to the middle of the upper surface of the connecting plate, and a connecting frame is fixedly connected to the upper surface of the fixing sleeve;

[0014] The above technical solution allows for the ecological movement of the equipment via a fixed sleeve.

[0015] Furthermore, the outer wall of the connecting frame is provided with a plurality of ball bearings, and the connecting frame is rotatably connected to the internal gear ring;

[0016] The above technical solution allows for steering by rotating the connecting frame and the internal gear ring.

[0017] Furthermore, a toothed groove is formed at the lower end of the inner wall of the internal toothed ring, and the toothed groove meshes with a gear;

[0018] The above technical solution allows the equipment to rotate by meshing the tooth groove with the gear.

[0019] Furthermore, the worm meshes with the worm wheel, and the toothed plate meshes with the worm wheel;

[0020] Through the above technical solution, the worm and worm wheel mesh, and the toothed plate and worm wheel mesh, the equipment can move up and down, and the worm wheel can self-lock.

[0021] Furthermore, a top plate is fixedly connected to the upper surface of the fixed column, and a base is fixedly connected to the lower surface of the bottom plate;

[0022] The above technical solution allows the device to be fixed using a base.

The device can be driven to move up or down by the toothed plate on the fixed column in conjunction with the first motor, worm gear and worm wheel, so that the device can detect a wider range. Furthermore, the device can be steered by the second motor in conjunction with the gear and the fixed plate. This mechanism can effectively expand the detection range of the device.

[0025] 2. The present invention proposes a fixed gas detector with concentration display function. By sliding the slider, the clamping frame can be driven to squeeze the spring. At the same time, the clamping frame will pull the clamping post to disengage from the display detector. At this time, the display detector can be quickly replaced or maintained, which can effectively improve the maintenance efficiency of the staff. Furthermore, with the cooperation of the second motor and the first motor, maintenance can be carried out more conveniently. Attached Figure Description
