Description

Technical Field

[0001] This utility model relates to the field of combustible gas detection technology, specifically to a combustible gas detector that is easy to install. Background Technology

[0002] Combustible gas detectors are crucial safety devices in industrial and civil environments. They are used to monitor the concentration of combustible gases in the air in real time and issue an alarm when the concentration reaches a dangerous threshold, thereby effectively preventing serious accidents such as fires and explosions.

[0003] Currently, most combustible gas detectors on the market are installed in a fixed manner. This involves pre-drilling holes in the wall or equipment surface and then using screws, bolts, or other fasteners to fix the detector body or its mounting base. The installation process is cumbersome, and the fixed installation position makes it very inconvenient to move the detector later due to process changes, equipment layout adjustments, or the need to find the optimal detection point. Furthermore, the existing installation methods for combustible gas detectors are relatively limited. For special occasions where the surface hardness is high, such as tiles, glass, or metal plates, or where drilling is not allowed, traditional drilling installation methods are difficult to implement or may cause permanent damage to the wall or equipment. Therefore, we propose a combustible gas detector that is easy to install. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 and Figure 4 This utility model provides a technical solution: a combustible gas detector that is easy to install, including a mounting box 1, an adjustable seat 4 that is retractable and adjustable is provided inside the mounting box 1, and a suction cup 5 is provided on the side of the adjustable seat 4 located outside the mounting box 1. The combustible gas detector body 3 is detachably installed on the surface of the mounting box 1.

[0022] A mounting plate 2 is fixedly attached to the surface of the combustible gas detector body 3. A fixing box 7 is installed on the surface of the mounting box 1. A connecting plate 12 is symmetrically slidably arranged on the surface of the mounting box 1, and a spring 14 is fixedly connected between the connecting plate 12 and the fixing box 7. A connecting block 18 is integrally provided at the end of the connecting plate 12. Fixing grooves 19 are symmetrically opened at both ends of the mounting plate 2, and the connecting block 18 is slidably inserted into the fixing groove 19.

[0023] It should be noted that the suction cup 5 is retractably located inside the mounting box 1. When needed, the position of the suction cup 5 at the end of the mounting box 1 can be adjusted so that the suction cup 5 is located outside the mounting box 1, which facilitates vacuum adsorption installation.

[0024] Please see Figure 2 Fixed rods 13 are fixedly connected to the corresponding sides of the fixed box 7. The surface of the connecting plate 12 is provided with sliding holes. The fixed rods 13 are slidably connected in the sliding holes. The spring 14 is sleeved on the outside of the fixed rods 13.

[0025] It should be noted that the setting of the fixing rod 13 can limit the sliding of the connecting plate 12, ensure the directional sliding of the connecting plate 12, and enable the connecting block 18 on the connecting plate 12 to be connected to the fixing groove 19 on the mounting plate 2.

[0026] Please see Figure 3A threaded rod 8 is rotatably connected to the fixed box 7 via a bearing, and the end of the threaded rod 8 extends into the mounting box 1. The adjustable seat 4 has a threaded hole on its surface, and the threaded rod 8 is threadedly connected to the threaded hole of the adjustable seat 4.

[0027] It should be noted that when the threaded rod 8 rotates, it is connected to the adjustable seat 4 via a thread, allowing the adjustable seat 4 to slide and extend inside the mounting box 1. During vacuum adsorption installation, the adjustable seat 4 is adjusted to the end of the mounting box 1, so that the suction cup 5 is located outside the mounting box 1, facilitating vacuum installation. When bolt installation is performed, the threaded rod 8 is controlled to rotate in the opposite direction, so that the adjustable seat 4 is located inside the mounting box 1, allowing the fixing plate 6 to fit against the mounting surface, facilitating bolt fastening.

[0028] Please see Figure 2 and Figure 3 The surface of the fixing box 7 is integrally provided with a connecting rod 17, and the bottom of the mounting plate 2 is provided with a connecting groove 20, in which the connecting rod 17 is slidably inserted.

[0029] It should be noted that the connecting rod 17 enables the initial connection between the combustible gas detector body 3 and the fixing box 7, thereby initially fixing the position of the combustible gas detector body 3 and facilitating the next step of reinforcing and fixing the combustible gas detector body 3.

[0030] Please see Figure 3 The four side walls of the mounting box 1 are all integrally provided with a fixing plate 6 at one end of the adjustable seat 4, and the surface of the fixing plate 6 is provided with countersunk holes.

[0031] It should be noted that the mounting plate 6 and the countersunk holes thereon allow the mounting box 1 to be directly fixed to the wall or equipment with screws in situations where vacuum adsorption is not suitable or permanent reinforcement is required, facilitating long-term use.

[0032] Please see Figure 2 Fixing holes 15 are provided at equal intervals on the outer side of the fixing rod 13, and a pin 16 is provided in the connecting plate 12. The pin 16 slides through the fixing hole 15.

[0033] It should be noted that the engagement of the pin 16 and the fixing hole 15 enhances the mechanical locking capability of the connection and effectively prevents accidental loosening due to vibration.

[0034] Please see Figure 3 The threaded rod 8 is fixedly connected to the outer side of one end of the fixed box 7 by a worm gear 9. The fixed box 7 is rotatably connected to a worm 10 through a bearing, and the worm 10 is meshed with the worm gear 9. The bottom of the fixed box 7 is rotatably connected to a turntable 11, and the end of the central shaft of the turntable 11 extends into the fixed box 7 and is fixedly connected to the worm 10.

[0035] It should be noted that when using this utility model, when temporary or semi-permanent installation is required on smooth surfaces such as glass, ceramic tiles, and metal plates, the mounting box 1 is placed on the selected flat mounting surface, so that the suction cup 5 on its back contacts the surface. The operator presses the mounting box 1 down, causing the suction cup 5 to deform and squeeze out the air inside, so that the mounting box 1 is firmly pressed on the mounting surface.

[0036] By rotating the turntable 11, the worm gear 10 is driven to rotate. Through the meshing connection between the worm gear 10 and the worm wheel 9, the worm wheel 9 rotates, which in turn drives the threaded rod 8 to rotate. Through the threaded connection between the adjustable seat 4 and the threaded rod 8, the adjustable seat 4 moves outward from the mounting box 1, thereby pushing the suction cup 5 to fit more tightly and flattened against the mounting surface, maximizing the suction force. The worm wheel 9 and worm gear 10 mechanism has a self-locking characteristic, which can prevent the threaded rod 8 from rotating in the opposite direction when subjected to vibration or pressure.

[0037] For applications where vacuum adsorption is not suitable or where permanent reinforcement is required, the mounting box 1 can be directly fixed to the wall or equipment using screws by using the fixing plate 6 on the side wall of the mounting box 1 and its countersunk holes. After the mounting box 1 is installed, the connecting plate 12 is pulled and slid to the end of the fixing rod 13, and then the position of the connecting plate 12 is fixed by the pin 16. The connecting groove 20 on the surface of the mounting plate 2 on the combustible gas detector body 3 is then snapped onto the top of the connecting rod 17.

[0038] Slide the combustible gas detector body 3 downwards, then remove the pin 16. Under the action of the spring 14, the connecting block 18 at the end of the connecting plate 12 corresponds to the fixing groove 19 on the mounting plate 2. The connecting block 18 slides into the fixing groove 19, and the spring 14 can tighten the connecting plate 12, so that the mounting plate 2 and the connecting plate 12 are firmly connected. Finally, insert the pin 16 into the fixing hole 15 on the connecting plate 12 and the fixing rod 13, so that the combustible gas detector body 3 is firmly installed.

[0039] Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," "third," or "fourth" may explicitly or implicitly include at least one of those features.
