Description

Technical Field

[0001] This utility model relates to the field of pipe clamp technology, specifically to an antifreeze pipe clamp for an aspirating smoke detector with a sampling hole. Background Technology

[0002] The anti-freeze clamp with sampling holes in an aspirating smoke detection system serves two main purposes. First, it's used for sampling. The sampling holes collect air samples from the surrounding environment to detect the presence of smoke particles. The system draws air in through the pipes and these sampling holes for analysis, thus enabling early fire smoke detection. Second, it provides anti-freeze protection. In colder environments, it prevents moisture inside the sampling tube from freezing. If the sampling tube freezes, it can cause blockages, affecting the normal collection and transmission of air samples and malfunctioning the detection system. The anti-freeze clamp effectively prevents this from happening.

[0003] Currently available antifreeze clamps for aspirating smoke detectors have several shortcomings. Traditional designs are rather rudimentary, typically featuring only a single sampling hole on the clamp. While this can barely meet basic air sampling needs, its limitations become glaringly apparent in harsh low-temperature environments. Its poor antifreeze performance makes it difficult to effectively block external cold air, easily causing moisture inside the tube to condense into ice, clogging the sampling pipe and interfering with normal system operation. Furthermore, under low-temperature conditions, the clamp's ability to securely hold the sampling tube decreases dramatically, significantly reducing its stability and increasing the risk of loosening, thus failing to provide a stable and reliable guarantee for detection operations. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes an antifreeze pipe clamp for an aspirating smoke detector with a sampling hole, which uses a material with good cold and frost resistance to make the pipe clamp, adds a pipe-holding structure, and increases the firmness.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: an antifreeze tube clamp for an inhalation-type smoke detector with a sampling hole, comprising:

[0006] The main board is designed to match the PTFE arc-shaped plates that bend backward on both sides of the smoke detection pipe. It has an integrally formed side lug at the rear edge and a model marking groove on the front.

[0007] The anti-slip component includes several elastic anti-slip strips and elastic anti-slip pads, which are respectively disposed on the inner side of the main board and the side ear. The elastic anti-slip strips are available in both horizontal and vertical configurations.

[0008] The sampling assembly includes a sampling hole on the front side of the motherboard and a sampling cover sealed inside the sampling hole, the sampling cover being removable.

[0009] Furthermore, the side lug is an arc-shaped plate that is consistent with the bending direction and angle of the motherboard, and the bending points of the upper and lower edges of the motherboard, as well as the points where they connect with the side lug and the bending points of the upper and lower edges of the side lug, are all smooth arc surfaces.

[0010] Furthermore, the height of the side ear is one-third of the motherboard height and it is located in the middle of the rear edge of the motherboard.

[0011] Furthermore, the elastic anti-slip strip is made of silicone, and the elastic anti-slip pad is made of PE foam.

[0012] Furthermore, the horizontal elastic anti-slip strips are located at the upper and lower ends of the inner wall of the motherboard. They are arc-shaped strips that match the curvature of the motherboard and are tightly fitted to the inner wall of the motherboard. The vertical elastic anti-slip strips are equidistantly arranged along the longitudinal direction of the motherboard and are located between the upper and lower horizontal elastic anti-slip strips.

[0013] Furthermore, the sampling cover is made of rubber, and the sampling cover is available in various models to match different specifications of sampling holes. The front end of the sampling cover of different models has different styles to distinguish the sampling hole models.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: This pipe clamp uses a polytetrafluoroethylene (PTFE) arc-shaped plate as the main body. PTFE is an excellent non-stick ice material. It has a low coefficient of friction and is non-adhesive, so ice adhesion to its surface is minimal, and frost and ice formation are difficult to occur on the PTFE material surface. The side lugs, elastic anti-slip strips, elastic anti-slip pads, and other components are made of silicone and PE foam, which can also adapt to low-temperature environments. The elasticity and anti-slip properties of silicone and the cushioning properties of PE foam maintain their effectiveness at low temperatures, ensuring that the overall functionality of the pipe clamp is not affected by low temperatures and effectively avoiding failure due to freezing.

[0015] By incorporating a side lug structure with a rationally designed height and position, it forms a clamping shape with the main board, allowing for more even force distribution during installation and a tight fit onto the smoke detection pipe. This not only ensures smooth installation and easy disassembly but also enhances stability, effectively preventing the pipe clamp from loosening or shifting. It guarantees a secure fixation to the pipe under various complex operating conditions, including low-temperature environments, ensuring normal operation of sampling and other functions. The elastic anti-slip strips and pads of the anti-slip components are both elastic, adapting to the low-temperature deformation of the pipe and automatically adjusting to ensure a good tightening effect. They also provide anti-slip properties, further guaranteeing the stability of the pipe clamp. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4 A frost-resistant pipe clamp for an inhalation-type smoke detector with a sampling hole includes: a main board 1, which is a PTFE arc-shaped plate that bends backward on both sides to match the smoke detector pipe. An edge lug 2 is integrally formed on the rear edge of the main board 1, and a model marking groove 3 is opened on the front edge. The edge lug 2 is an arc-shaped plate with the same bending direction and angle as the main board 1. The upper and lower edges of the main board 1, as well as the junction with the edge lug 2, and the upper and lower edges of the edge lug 2 are all smooth arc surfaces, which can better fit the smoke detector pipe, prevent scratching the pipe during installation, and facilitate safe disassembly and assembly, ensuring smooth and tight installation. The height of the edge lug 2 is one-third of the height of the main board 1 and is located in the middle of the rear edge of the main board 1, ensuring even force distribution on the clamp when bending the edge lug 2, avoiding damage, and requiring less effort to bend. The model marking groove 3 can be engraved with the corresponding main board 1 model for easy matching with the pipe.

[0024] Combined with appendix Figure 2 Appendix Figure 3The anti-slip component includes several elastic anti-slip strips 4 and elastic anti-slip pads 5. The elastic anti-slip strips 4 and elastic anti-slip pads 5 are respectively disposed on the inner side of the main board 1 and the side lug 2. The elastic anti-slip strips 4 are available in both horizontal and vertical directions. The elastic anti-slip strips 4 are made of silicone, and the elastic anti-slip pads 5 are made of PE foam. The silicone elastic anti-slip strips 4 have good elasticity and excellent anti-slip performance, while the PE foam elastic anti-slip pads 5 are soft and have good cushioning properties. The combination of the two can enhance the anti-slip and protective functions of the pipe clamp, and can also adapt to the deformation of the pipeline caused by weather changes, always ensuring a good clamping and fixing effect. The horizontal elastic anti-slip strip 4 is located at the upper and lower ends of the inner wall of the main board 1. It is an arc-shaped strip that matches the curvature of the main board 1 and is tightly fitted to the inner wall of the main board 1. The vertical elastic anti-slip strip 4 is equidistantly arranged along the longitudinal direction of the main board 1 and located between the upper and lower horizontal elastic anti-slip strips 4. This layout can enhance the friction between the inner side of the main board 1 and the pipe in all directions, ensuring that the pipe clamp firmly clamps the pipe.

[0025] Combined with appendix Figure 1 Appendix Figure 4 Appendix Figure 5 The sampling component includes a sampling hole on the front side of the motherboard 1 and a sampling cover 6 sealed inside the sampling hole. The sampling cover 6 is detachable. The sampling cover 6 is made of rubber and comes in various models to match different specifications of sampling holes. Different models of sampling covers 6 have different styles at the front end to distinguish the sampling hole model. The rubber material has good sealing performance, and the various models and styles of sampling covers 6 facilitate adaptation to different specifications of sampling holes, making it convenient and accurate to use and distinguish.

[0026] The specific implementation method of this utility model is as follows: First, according to the pipe specifications, select a main board 1 with a suitable model number printed in the model marking groove 3, and whose sampling hole matches the sampling hole on the pipe. The specifications of the sampling hole of the main board 1 can be determined by the style of the sampling cover 6 sealed at the sampling hole of the main board 1. Align the side of the main board 1 with the elastic anti-slip strip 4 and elastic anti-slip pad 5 with the smoke detection pipe to be installed. Hold the side ear 2 and gently bend the outside to install the pipe clamp in a suitable position on the pipe. The pipe enters the inside of the main board 1 through the opening formed between the two side ears 2, ensuring that the main board 1 and the side ear 2 are tightly fitted to the outer wall of the pipe, and that the elastic anti-slip strip 4 and elastic anti-slip pad 5 are in close contact with the pipe, and that the sampling hole on the main board 1 is aligned with the sampling hole of the pipe. The elastic anti-slip strip 4 made of silicone material and the elastic anti-slip pad 5 made of PE foam material increase friction and cushioning, completing the installation and fixing work. When sampling is required, the relevant sampling work can be carried out through the sampling hole at the through hole of the sampling cover 6.
