Description

Technical Field

[0001] This utility model relates to the field of chemical leak detector technology, and in particular to a fast-response chemical leak detector. Background Technology

[0002] A chemical leak detector is a device specifically designed to detect gas leaks in chemical environments. It is primarily used to prevent and respond to potential leaks during chemical production processes. These detectors are typically installed in chemical production areas, such as tank farms and production lines, to monitor changes in gas concentration in the environment in real time, ensuring production safety. For example, the patent application CN221395267U describes a chemical hazardous materials leak detector comprising a level tube mounting base, a level display tube, and a detector body. The level display tube is fixedly installed inside the level tube mounting base, and the detector body is located on one side of the level tube mounting base. Floating detectors are installed at both ends and inside the level display tube. The structure uses changes in the liquid level of a float ball to detect and warn of chemical hazardous material leaks, and then uses the main body of the detector to detect and warn of air leaks, achieving dual leak detection for more accurate and safer leak detection. When detecting leaks at different locations, the main body of the detector can be quickly separated from the fixing ring, and the docking plug can be disconnected from the docking hole. Then, the main body of the detector can be moved to allow the leak detection head to detect leaks at different locations. However, the main body of the detector is installed using a fixing ring. Over time, the fixing ring may loosen when holding the main body of the detector, causing the main body of the detector to fall and be damaged. Utility Model Content

[0003] The main objective of this invention is to provide a fast-response chemical leak detector that can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A fast-response chemical leak detector includes a level tube mounting base and a detector body. A level display tube is installed inside the level tube mounting base, and mounting plates are fixedly connected to both the upper and lower ends of the level display tube. A mounting connecting rod is fixedly connected to the other end of the level tube mounting base. An operation button is installed near the lower end of the front surface of the detector body, and a display screen is installed in the middle of the front surface of the detector body. A detection head mounting rod is fixedly connected to the upper end of the detector body, and a leak detection head is fixedly installed on the upper end of the detection head mounting rod. A connection structure is provided between one end of the detector body and the other end of the mounting connecting rod.

[0006] Preferably, the connection structure includes a connecting block, a fixing plate, a wedge block, a rectangular insert block, a circular slot, a rectangular slot, a circular rod, a circular through hole, a circular slider, a reset spring, a circular slide groove, a circular guide rod, and a rectangular connecting plate.

[0007] Preferably, connecting blocks are fixedly installed on both the front and rear surfaces of the detector body near the upper end, and a fixing plate is fixedly installed on the other end surface of the mounting connecting rod. Rectangular slots are opened on the other end surface of the fixing plate near the front and rear ends.

[0008] Preferably, a rectangular insert is fixedly installed on one end surface of the connecting block, a wedge block is fixedly installed on one end surface of the rectangular insert, and a rectangular insert is inserted into the rectangular slot.

[0009] Preferably, a circular groove is provided at the upper end of the rectangular slot inside the fixing plate, a circular slider is slidably installed in the circular groove, and a circular locking rod is fixedly installed in the middle of the lower surface of the circular slider.

[0010] Preferably, a circular through hole is provided in the middle of the lower surface of the circular groove, and a circular slot is provided on the upper surface of the rectangular insert block, into which a circular locking rod is inserted.

[0011] Preferably, a circular guide rod is fixedly installed in the middle of the upper surface of the circular slider, a return spring is sleeved on the upper end of the circular slider on the outer surface of the circular guide rod, and a rectangular connecting plate is fixedly installed on the upper end of the circular guide rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the connection structure allows the rectangular connecting plate to be pulled upwards when the main body of the detector is taken out, causing the circular locking rod to disengage from the circular slot on the upper surface of the rectangular insert and retract into the circular through hole. Then, the main body of the detector is pulled to the other end, thereby causing the rectangular insert fixedly installed at one end of the connecting block to disengage from the rectangular slot on the other end of the fixing plate, allowing the main body of the detector to be removed. The connection is stable, preventing the main body of the detector from falling and being damaged. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-3 As shown, a fast-response chemical leak detector includes a liquid level tube mounting base 1 and a detector body 4. A liquid level display tube 2 is installed inside the liquid level tube mounting base 1. Mounting plates 201 are fixedly connected to both the upper and lower ends of the liquid level display tube 2. A mounting connecting rod 3 is fixedly connected to the other end of the liquid level tube mounting base 1. An operation button 401 is installed on the front surface of the detector body 4 near the lower end. A display screen 402 is installed in the middle of the front surface of the detector body 4. A detection head mounting rod 403 is fixedly connected to the upper end of the detector body 4. A leak detection head 404 is fixedly installed on the upper end of the detection head mounting rod 403. A connection structure 5 is provided between one end of the detector body 4 and the other end of the mounting connecting rod 3.

[0020] The connecting structure 5 includes a connecting block 501, a fixing plate 502, a wedge block 503, a rectangular insert block 504, a circular slot 505, a rectangular slot 506, a circular locking rod 507, a circular through hole 508, a circular slider 509, a return spring 510, a circular slide groove 511, a circular guide rod 512, and a rectangular connecting plate 513; the connecting blocks 501 are fixedly installed on the front and rear surfaces of the detector body 4 near the upper end, and a fixing plate 501 is fixedly installed on the other end surface of the mounting connecting rod 3. 2. A rectangular slot 506 is provided on the other end surface of the fixing plate 502 near both the front and rear ends; a rectangular insert 504 is fixedly installed on one end surface of the connecting block 501, and a wedge block 503 is fixedly installed on one end surface of the rectangular insert 504. The rectangular insert 504 is inserted into the rectangular slot 506; a circular groove 511 is provided on the upper end of the rectangular slot 506 inside the fixing plate 502, and a circular slider 509 is slidably installed in the circular groove 511. The lower surface of the circular slider 509 is fixed in the middle. A circular locking rod 507 is fixedly installed; a circular through hole 508 is opened in the middle of the lower surface of the circular slide groove 511; a circular slot 505 is opened in the upper surface of the rectangular insert block 504, and the circular locking rod 507 is inserted into the circular slot 505; a circular guide rod 512 is fixedly installed in the middle of the upper surface of the circular slider 509; a return spring 510 is sleeved on the upper end of the circular slider 509 on the outer surface of the circular guide rod 512; a rectangular connecting plate 513 is fixedly installed in the upper end of the circular guide rod 512.
