Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, specifically to a gas detection alarm device. Background Technology

[0002] A gas detector alarm is a device used to detect the concentration of certain gases in the air and issue an alarm when the gas concentration exceeds the standard. With the increasing demands of industrial production and safety, gas detector alarms are widely used in many fields, such as chemical plants, coal mines, and laboratories.

[0003] Existing gas detectors typically require a complex installation process to assemble the detector body with the probe or other components. Especially during installation or disassembly, specialized tools or manual intervention are needed. This traditional installation method is not only cumbersome but also prone to errors, affecting the normal operation and accuracy of the gas detector.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings and provide a gas detection alarm.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a gas detection alarm, including a gas detection alarm body and a probe disposed on the gas detection alarm body for detecting gas concentration. The probe is provided with a housing, and the housing is adapted to the gas detection alarm body to provide an installation port. The inner wall of the installation port is provided with two symmetrical through grooves distributed along the height direction of the installation port. The bottom of the through groove is provided with an arc groove along the circumference of the installation port.

[0007] The mounting component is disposed on the gas detector alarm body, and the gas detector alarm body is moved down and rotated, so that the structure formed on the mounting component rotates and is limited in the arc groove;

[0008] An air intake pump is installed on one side of the gas detector and alarm body to draw in gas under negative pressure into the gas detector and alarm body for monitoring by a probe.

[0009] Furthermore, the installation assembly includes a support block disposed on the gas detector body and limiting members symmetrically disposed on both sides of the support block.

[0010] Furthermore, the limiting member includes two vertical spring pieces and a trapezoidal block with a cavity structure. The inner vertical spring piece passes through and is disposed on the support block, while the outer vertical spring piece is disposed on the support block at intervals relative to the inner vertical spring piece. The bottoms of the two vertical spring pieces are welded to the trapezoidal block in a closed manner.

[0011] Pressing the outer vertical spring piece along the radial direction of the support block towards the inner vertical spring piece causes the trapezoidal block with the cavity structure to undergo elastic deformation downwards, thereby causing the elastically deformed trapezoidal block to rotate and fit along the inner groove of the arc groove from the position of the through groove.

[0012] Furthermore, a limiting groove is provided on the side of the arc groove away from the through groove;

[0013] The height of the limiting groove is adapted to the height of the trapezoidal block, and under the action of elasticity, the trapezoidal block will restore its initial height and be placed in the limiting groove for limiting.

[0014] Furthermore, an air inlet is provided on the gas detector body on the other side opposite to the air intake pump.

[0015] Furthermore, a mounting plate is movably provided on the back of the gas detection alarm body, and mounting screw holes are provided at the end corners of the mounting plate.

[0016] Furthermore, the support block is provided with an annular groove, a threaded ring is provided in the annular groove, and an operating plate is provided on one side of the threaded ring.

[0017] Compared with the prior art, the present invention has the following advantages: The present invention, through the installation components, can conveniently install or separate the gas detector alarm body and housing, simplifying the traditional installation process and enabling operators to quickly and easily install and disassemble the equipment, thereby improving the ease of operation; In addition, through the air pump, negative pressure can be used to draw in gas into the gas detector alarm body for monitoring by the probe.

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on 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.

[0024] like Figure 1-3 As shown, the gas detection alarm of this utility model includes a gas detection alarm body 1 and a probe disposed on the gas detection alarm body 1 for detecting gas concentration. The probe is provided with a housing 2. The housing 2 is adapted to the gas detection alarm body 1 and is provided with an installation port. The inner wall of the installation port is provided with two symmetrical through grooves 3 distributed along the height direction of the installation port. The bottom of the through grooves 3 is provided with an arc groove 31 along the circumference of the installation port.

[0025] Mounting component 4 is mounted on the gas detector alarm body 1. The gas detector alarm body 1 is moved down and rotated, so that the structure formed on the mounting component 4 rotates and is limited in the arc groove 31.

[0026] The suction pump 5 is located on one side of the gas detector alarm body 1 and is used to draw in gas under negative pressure into the gas detector alarm body 1 for monitoring by a probe.

[0027] In practice, the gas detector alarm body 1 is installed or separated from the mounting port machined at the upper end of the housing 2 through the mounting component 4. Since the mounting component 4 moves down and rotates sequentially in the connecting cavity of the through groove 3 and the arc groove 31, the convenience of the installation operation is improved and the operation is simple.

[0028] Furthermore, by installing an air pump 5 in a groove machined on one side of the gas detector alarm body 1, negative pressure can be used to draw in gas into the gas detector alarm body 1 for monitoring by a probe, thereby improving gas detection efficiency.

[0029] It should be noted that the inner wall of the mounting opening on the housing 2 is symmetrically machined with two through grooves 3, and an arc groove 31 is machined on one side of the lower end of the through grooves 3.

[0030] In one embodiment, the mounting assembly 4 includes a support block 41 disposed on the gas detector body 1 and limiting members 42 symmetrically disposed on both sides of the support block 41. This design, by using screws to fix the end of the probe mounted on the gas detector body 1 to the support block 41, and symmetrically welding the limiting members 42 on both sides of the support block 41, allows for the vertical insertion of the two symmetrically welded limiting members 42 into the through groove 3. Rotating the gas detector body 1 moves the limiting members 42 along the inner groove of the arc groove 31 to the side of the arc groove 31 away from the through groove 3 for limiting, thus achieving the installation and separation of the gas detector body 1 and the housing 2, simplifying the operation.

[0031] In one embodiment, the limiting member 42 includes two vertical spring pieces and a trapezoidal block with a cavity structure. The inner vertical spring piece passes through and is disposed on the support block 41, and the outer vertical spring piece is disposed on the support block 41 at intervals relative to the inner vertical spring piece. The bottoms of the two vertical spring pieces are closed and welded to the trapezoidal block.

[0032] By pressing the outer vertical spring piece towards the inner vertical spring piece along the radial direction of the support block 41, the trapezoidal block with the cavity structure undergoes downward elastic deformation, thereby causing the elastically deformed trapezoidal block to rotate along the inner groove of the arc groove 31 from the position of the through groove 3. This design, with two vertical spring pieces spaced apart on the circumference of the support block 41, and a movable gap between the outer and inner vertical spring pieces, and a trapezoidal block with a cavity structure welded to the bottom of the two vertical spring pieces, causes the upper inclined surface of the trapezoidal block to elastically deform downward during the radial pressing of the outer vertical spring piece towards the inner vertical spring piece along the support block 41. This causes the elastically deformed trapezoidal block to rotate along the inner groove of the arc groove 31 from the position of the through groove 3, thus achieving the limiting installation of the limiting member 42 within the inner groove of the arc groove 31.

[0033] In one embodiment, a limiting groove 32 is provided on the side of the arc groove 31 away from the through groove 3;

[0034] The height of the limiting groove 32 is adapted to the height of the trapezoidal block. Under elastic action, the trapezoidal block will return to its initial height and be positioned within the limiting groove 32 for limiting. This design, with the limiting groove 32 machined on the side of the arc groove 31 away from the through groove 3, and the height of the limiting groove 32 adapted to the initial height of the trapezoidal block, ensures that once the trapezoidal block loses its load, it will return to its initial height under elastic action, thus locking the trapezoidal block within the limiting groove 32.

[0035] In one embodiment, an air inlet is provided on the gas detector body 1 on the side opposite to the suction pump 5. This design, with the air inlet machined on the side of the gas detector body 1 opposite to the suction pump 5, allows the negative pressure generated after the suction pump 5 is activated to quickly draw gas into the housing 2 for measurement and analysis by a probe.

[0036] In one embodiment, a mounting plate 6 is movably mounted on the back of the gas detector alarm body 1, and mounting screw holes 61 are provided at the end corners of the mounting plate 6. This design, by using the mounting plate 6, which is movably mounted through a slot on the back of the gas detector alarm body 1, and the mounting screw holes 61 machined at the end corners of the mounting plate 6, allows the gas detector alarm body 1, assembled on the housing 2, to be bolted to the desired installation position, facilitating gas detection in a predetermined area.

[0037] In one embodiment, an annular groove 43 is circumferentially provided on the support block 41, and a threaded ring 44 is provided inside the annular groove 43. An operating plate is provided on one side of the threaded ring 44. With this design, the annular groove 43 is machined on the support block 41, and the inner vertical spring piece formed on the limiting member 42 is welded to the inner wall of the annular groove 43. The part of the vertical spring piece that coincides with the inner wall of the annular groove 43 and the inner wall of the annular groove 43 are both machined with external threads by turning. The internal thread is also machined inside the threaded ring 44. When the threaded ring 44 is rotated and moved down in the annular groove 43, the relative distance between the two vertical spring pieces is locked, preventing the outer vertical spring piece from moving closer to the inner vertical spring piece by accident, thus ensuring the connection stability of the limiting member 42 in the limiting groove 32.

[0038] It should be noted that the operating plate welded to the top of the threaded ring 44 improves the ease of operation.

[0039] It should be noted that the distance between the two vertical spring pieces is the same as the difference between the inner and outer diameters of the threaded ring 44. The threaded ring 44 can limit the distance between the two vertical spring pieces, prevent the outer vertical spring piece from elastically displacing, and ensure the locking effect.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0041] It should be noted that if the embodiments of this utility model involve directional indicators, such as up, down, left, right, front, back, etc., the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.
