[0028] Reference Figure 1 and Figure 2The utility model provides an embodiment: an alarm detection rod for a chemical calibration room, comprising two shells 1, the rear sides of the two shells 1 are fixedly connected with a connecting shell 3, the front and rear sides of the inner top wall of the top connecting shell 3 are fixedly connected with a clamping plate 4, the right side of the inner wall of the bottom connecting shell 3 is fixedly connected with an electric telescopic rod 5, the output end of the electric telescopic rod 5 is fixedly connected with a displacement plate 6, the front and rear ends of the left side of the displacement plate 6 are both provided with a clamping hole 7, the bottoms of the two clamping plates 4 are respectively clamped with the corresponding clamping holes 7, and the inner bottom wall of the bottom shell 1 is fixedly installed with An alarm detection device 11, a detection rod 12 is fixedly installed on the right side of the alarm detection device 11, a fixing plate 16 is fixedly connected to the right side of the bottom shell 1, a locking assembly is arranged on the front side of the top shell 1, and a cleaning mechanism 2 is arranged on the right side of the shell 1; the locking assembly includes a rotating column 8, the outer side of the rotating column 8 is rotatably connected to the front side of the top shell 1, a rotating plate 9 is fixedly connected to the outer wall of the rotating column 8, a locking groove 10 is opened on the front side of the bottom shell 1, the bottom rear side of the rotating plate 9 is engaged with the locking groove 10, and a control switch 19 is fixedly connected to the left side of the bottom shell 1;

[0029] Specifically, the electric telescopic rod 5 is started so that its output end will drive the displacement plate 6 to move to the left. During this process, the two engaging plates 4 will be separated from the engaging holes 7 provided inside the displacement plate 6, respectively. In this way, the engaging connection between the engaging plate 4 and the displacement plate 6 is cancelled. Next, the operator rotates the rotating plate 9. Under the rotation of the rotating column 8, the bottom of the rotating plate 9 will be separated from the locking groove 10. At this time, the operator can easily pull the top shell 1 to separate the two connecting shells 3. In this way, the two shells 1 have completed the disassembly work and realized one-button disassembly. This one-button disassembly design not only simplifies the disassembly process, but also greatly improves the maintenance efficiency. Maintenance personnel no longer need to spend a lot of time and energy to disassemble complex components, thereby avoiding the waste of maintenance time.

[0030] Reference Figure 1 and Figure 3 The cleaning mechanism 2 includes a cleaning shell 201, the left side of the cleaning shell 201 is arranged on the right side of the outer shell 1, the upper and lower ends of the inner wall of the cleaning shell 201 are fixedly connected with return springs 202, the rear ends of the two return springs 202 are fixedly connected with cleaning sponge plates 203, the upper and lower sides of the cleaning shell 201 are fixedly connected with connecting plates 204, the upper and lower sides of the fixed plate 16 are provided with sliding grooves 205, the adjacent sides of the two connecting plates 204 are respectively slidably connected with the corresponding sliding grooves 205, and the front side of the cleaning shell 201 is fixedly connected with a handle 206;

[0031] Specifically, when the handle 206 is pulled, the connecting plate 204 will slide along the set path under the guidance of the slide groove 205. The design of this sliding connection not only ensures the smoothness of the movement, but also ensures that the cleaning shell 201 can accurately move along the predetermined path. One end of the reset spring 202 is fixed to the cleaning shell 201, and the other end is connected to the front side of the cleaning sponge plate 203. When the cleaning shell 201 is reciprocating, the internal cleaning sponge plate 203 will also move accordingly. Since the cleaning sponge plate 203 is in close contact with the outer wall of the detection rod 12, it can effectively remove dust and dirt on the outer wall of the detection rod 12 during the movement. In this way, the risk of dust or dirt adhering to the outer wall of the detection rod 12 affecting the detection effect of the alarm detection rod is reduced, thereby improving work efficiency.

[0032] Reference Figure 1 , Figure 2 and Figure 3 , the control switch 19 is electrically connected to the electric telescopic rod 5 and the alarm detection device 11 respectively; the front and rear sides of the bottom wall of the top shell 1 are fixedly connected with sealing plates 14, and the front and rear sides of the top wall of the bottom shell 1 are provided with sealing grooves 15, and the bottoms of the two sealing plates 14 are respectively engaged with the corresponding sealing grooves 15; a protective shell 17 is provided on the left side of the control switch 19, and the right side of the protective shell 17 is rotatably connected to the left side of the bottom shell 1 through a hinge;

[0033] Specifically, the device can be opened and closed by means of a control switch 19 electrically connected to the electric telescopic rod 5 and the alarm detection device 11 respectively. The bottoms of the two sealing plates 14 are respectively engaged with the corresponding sealing grooves 15, so that the sealing effect of the two outer shells 1 can be increased. The control switch 19 can be protected and prevented from being accidentally touched by the protective shell 17.

[0034] Reference Figure 1 The front and rear ends of the left sides of the two shells 1 are fixedly connected with positioning bolts 13; the top wall of the bottom connecting shell 3 is fixedly connected with a rubber ring 18;

[0035] Specifically, the detection rod is easily installed by means of a plurality of positioning bolts 13 , and the wear of the two connection shells 3 is reduced by means of the rubber ring 18 .

[0036] Working principle: When the disassembly work starts, the electric telescopic rod 5 is started, so that the output end of the electric telescopic rod 5 drives the displacement plate 6 to move to the left, so that the two clamping plates 4 are separated from the clamping holes 7 opened inside the displacement plate 6, thereby canceling the clamping connection between the clamping plate 4 and the displacement plate 6. By rotating the rotating plate 9, the bottom of the rotating plate 9 is separated from the locking groove 10 under the rotation of the rotating column 8, and then the top shell 1 is pulled to separate the two connecting shells 3. The two shells 1 complete the disassembly work, thereby achieving the purpose of one-button disassembly, which is convenient for alarm The detector rod can be maintained and calibrated, which improves maintenance efficiency and avoids wasting maintenance time. By pulling the handle 206, the cleaning shell 201 can complete the reciprocating motion in the left and right directions under the action of the sliding connection between the two connecting plates 204 and the corresponding slide grooves 205, and then the cleaning sponge plate 203 fixed inside the cleaning shell 201 by two return springs 202 reciprocates together, so that the outer wall of the detection rod 12 can be cleaned, which reduces the dust or dirt attached to the outer wall of the detection rod 12 and affects the detection effect of the alarm detection rod, thereby improving work efficiency.
