[0002] A gas detector is an instrument tool for detecting gas leakage concentration, mainly referring to a portable handheld gas detector. Semiconductor gas detectors are manufactured using the principle that the electrical conductivity of some metal oxide semiconductor materials changes with the change of ambient gas composition at a certain temperature. Gas detectors are usually equipped with sound and light alarms. The detection results of the gas detector can not only be accurately displayed on the display screen, but also alert the detector through the alarm device.

[0003] The fixed gas detector has a reserved interface for installing the alarm. The alarm and the detector are usually fixed by threads. The alarm needs to be rotated as a whole during installation, and a certain amount of space is required for the alarm to rotate. In some cases where an alarm needs to be temporarily installed, if the detector has been fixed to the wall, the detector needs to be removed before the alarm can be successfully installed. The installation process is more troublesome. Utility Model Content

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. "Multiple" in this specification refers to two or more.

[0021] In the description of this specification, the description with reference to the terms "embodiment", "one embodiment" and "one implementation" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or implementation are included in at least one embodiment or implementation of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0022] Combination Figure 1-5 As shown, an embodiment of the utility model provides a gas detection alarm device, including: an alarm housing 1, a connecting sleeve 2 is fixedly connected to one side of the alarm housing 1, a tube cap 21 is fixedly connected to the end of the connecting sleeve 2 away from the alarm housing 1, a connecting insert 3 is embedded in the connecting sleeve 2, the connecting insert 3 is fixed to a port on the detector connected to the alarm, a fixed clamping ring 31 is fixedly connected to the end of the connecting insert 3 away from the detector, a movable clamping ring 32 is movably sleeved on the connecting insert 3, a plurality of groups of reset springs 33 are evenly arranged between the movable clamping ring 32 and the fixed clamping ring 31, the movable clamping ring 32 is connected to the fixed clamping ring 31 through the reset spring 33, and the connecting insert 3 and the connecting sleeve 2 are stably connected through the fixed clamping ring 31 and the movable clamping ring 32.

[0023] It should be noted that the diameters of the fixed snap ring 31 and the movable snap ring 32 are slightly larger than the inner diameter of the barrel cap 21. After the fixed snap ring 31 and the movable snap ring 32 are pushed into the barrel cap 21 by external force, the connecting sleeve 2 and the connecting embedded cylinder 3 are connected to prevent the connecting embedded cylinder 3 from falling off from the connecting embedded cylinder 3 at will. At the same time, since there is a reset spring 33 between the movable snap ring 32 and the fixed snap ring 31, the reset spring 33 pushes the movable snap ring 32 and the fixed snap ring 31 apart, so that the fixed snap ring 31 and the movable snap ring 32 are respectively against the two ends of the barrel cap 21. For details, see Figure 5 As shown, the friction between the fixed snap ring 31, the movable snap ring 32 and the tube cap 21 makes the connection sleeve 2 and the connection insert 3 stable and not shaken.

[0024] Specifically: the diameter of the tube cap 21 is larger than the diameter of the connecting sleeve 2 , the cross section of the tube cap 21 is an L-shaped structure, and the inner diameter of the end of the tube cap 21 away from the connecting sleeve 2 is the same as the inner diameter of the connecting sleeve 2 .

[0025] Specifically, a plurality of groups of zoom grooves 22 are evenly arranged on the surface of the tube cap 21, and the zoom grooves 22 are of an "I"-shaped blind groove structure.

[0026] It should be noted that the barrel wall of the barrel cap 21 can be expanded to a certain extent through the expansion groove 22, so that the fixed snap ring 31 and the movable snap ring 32 whose diameters are larger than the inner diameter of the barrel cap 21 can smoothly enter the interior of the barrel cap 21. Since the barrel cap 21 has an L-shaped cross-section, the fixed snap ring 31 and the movable snap ring 32 will be stuck after entering the interior of the barrel cap 21 and cannot be detached from the barrel cap 21 without external force.

[0027] Specifically: the cross section of the fixed snap ring 31 is a 1 / 4 circular structure, the fixed snap ring 31 is annular in structure as a whole, the movable snap ring 32 has the same structure as the fixed snap ring 31, and when the movable snap ring 32 compresses the reset spring 33 until it is close to the fixed snap ring 31, the movable snap ring 32 and the fixed snap ring 31 can be combined to form a ring with a semicircular cross section. For details, see Figure 4 shown.

[0028] It should be noted that when the connecting insert 3 is subjected to a laterally applied thrust and enters the connecting sleeve 2, the movable snap ring 32 needs to first overcome the resistance of the return spring 33 and merge with the fixed snap ring 31, so that the outer surface of the combined ring is arc-shaped. When the arc-shaped surface contacts the port of the tube cap 21 and is subjected to a thrust toward the inside of the tube cap 21, the tube cap 21 will expand, and the fixed snap ring 31 and the movable snap ring 32 will enter the tube cap 21 naturally.

[0029] Specifically, the outer diameters of the fixed snap ring 31 and the movable snap ring 32 are larger than the inner diameter of the end of the tube cap 21 away from the connecting sleeve 2 , but are the same as the inner diameter of the end of the tube cap 21 close to the connecting sleeve 2 .

[0030] The working principle of the utility model is as follows: when the alarm and the detector are installed, first align the end of the connecting sleeve 2 with the connecting sleeve 3, and then apply lateral thrust to the detector and the alarm respectively to push the connecting sleeve 3 into the connecting sleeve 2. The process is just like Figures 4 to 5 As shown, the installation is completed after the connecting sleeve 3 is embedded in the connecting sleeve 2. If the alarm and the detector need to be separated, it is only necessary to apply pulling force to the alarm and the detector respectively to remove the connecting sleeve 3 from the connecting sleeve 2.

[0031] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
