Description

Technical Field

[0001] This utility model relates to the field of air conditioning refrigeration pipe installation technology, and more specifically, to a hose anti-bending protection structure for refrigeration and air conditioning equipment piping fittings. Background Technology

[0002] Air conditioning hoses are a crucial component of air conditioning systems, responsible for delivering refrigerant to the air conditioning equipment to ensure proper cooling and heating functions. They act like the "blood vessels" of the air conditioning system, connecting various components and directly affecting the operating efficiency and lifespan of the unit. If the hoses malfunction, cooling and heating efficiency will drop significantly, impacting the comfort of the living environment.

[0003] In air conditioning systems, the air conditioning hose is a crucial component connecting the indoor and outdoor units. Its installation stability and operational reliability are paramount. However, a review of existing air conditioning hose protection devices reveals the following shortcomings:

[0004] (1) Air conditioning hoses are prone to bending during use, which can lead to poor or even blocked medium flow;

[0005] (2) When it is necessary to replace a damaged or different specification of helical spring, it is not convenient to quickly install and disassemble the helical spring.

[0006] Therefore, we have made improvements and proposed a bend-resistant protection structure for hoses in refrigeration and air conditioning equipment piping fittings. Utility Model Content

[0007] The purpose of this utility model is to address the problems that existing air conditioning hoses are prone to bending during use, leading to poor or even blocked medium flow; and that it is inconvenient to quickly install and remove the spiral springs when it is necessary to replace damaged or different specifications of spiral springs.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A bend-resistant protective structure for hoses and piping fittings in refrigeration and air conditioning equipment is provided to improve the above-mentioned problems.

[0010] The present invention is as follows:

[0011] It includes a first positioning clamp and a second positioning clamp located above the first positioning clamp, and also includes,

[0012] A helical spring is disposed between the first positioning clamp and the second positioning clamp, and is used to wrap around the outer wall of the air conditioning hose to prevent the air conditioning hose from bending.

[0013] The first docking assembly is installed at the connection between the first positioning hoop and the bottom end of the spiral spring, and is used to connect the bottom end of the spiral spring to the first positioning hoop.

[0014] The second docking assembly is installed at the connection between the second positioning clamp and the top of the helical spring, and is used to connect the top of the helical spring to the second positioning clamp.

[0015] An anti-slip limiting component is provided, which is evenly distributed on the inner sidewalls of the first positioning hoop and the second positioning hoop, and is used to prevent the air conditioning hose from shifting.

[0016] As a preferred technical solution of this utility model, the first docking assembly includes an annular seat fixedly installed on the outer wall of the first positioning hoop. The groove wall of the annular seat is provided with a threaded groove. The bottom end of the spiral spring is rotatably connected to a fixing rod. A gripping handle is fixedly installed on the outer wall of the upper section of the fixing rod. The outer wall of the end of the fixing rod near the annular seat is fixedly provided with uniformly distributed external threads. The threaded section of the fixing rod is connected to the groove wall of the annular seat by threads.

[0017] As a preferred technical solution of this utility model, except that the annular seat in the second docking assembly is fixedly installed on the outer wall of the second positioning hoop, the rest of the structure of the second docking assembly is the same as that of the first docking assembly, and the first docking assembly and the second docking assembly are arranged opposite to each other.

[0018] As a preferred technical solution of this utility model, the first positioning hoop includes symmetrically arranged arc-shaped plates, the junction of the two sets of arc-shaped plates is rotatably connected, the other ends of the two sets of arc-shaped plates are connected by fixing bolts, and an arc-shaped groove is provided on the inner side wall of any arc-shaped plate.

[0019] As a preferred technical solution of this utility model, the anti-slip limiting component includes a telescopic rod fixedly installed on the wall of the arc-shaped groove, an arc-shaped anti-slip plate fixedly installed on the telescopic end of the telescopic rod, and a spring fixedly disposed between the wall of the arc-shaped groove and the arc-shaped anti-slip plate and sleeved on the outer wall of the telescopic rod.

[0020] As a preferred technical solution of this utility model, the arc-shaped anti-slip plate has a rubber layer at one end near the air conditioning hose.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] In the solution of this utility model:

[0023] 1. The spiral spring set between the first positioning clamp and the second positioning clamp can be wound around the outer wall of the air conditioning hose, providing support and protection for the air conditioning hose. This effectively prevents the air conditioning hose from bending during use, ensures the normal flow of the medium inside the air conditioning hose, and solves the problem in the prior art that the air conditioning hose is prone to bending during use, leading to poor medium flow or even blockage.

[0024] 2. By setting the first docking component and the second docking component, the bottom end and the top end of the spiral spring are respectively connected to the first positioning hoop and the second positioning hoop. The first docking component and the second docking component adopt the method of threaded connection between the ring seat and the fixed rod, which realizes that when the spiral spring is damaged or needs to be replaced with a spring of different specifications, it can be operated quickly, which solves the problem in the prior art that it is not convenient to quickly install and disassemble the spiral spring when it is necessary to replace the damaged or different specifications of the spiral spring.

[0025] 3. The first positioning clamp is composed of symmetrically arranged arc-shaped plates. The two sets of arc-shaped plates are rotatably connected at the junction, and the other end is connected by a fixing bolt. This allows the positioning clamp to adapt to air conditioning hoses of different diameters, thus improving the applicability of the positioning clamp.

[0026] 4. By setting anti-slip limiting components evenly distributed on the inner walls of the first and second positioning clamps, when the air conditioning hose is installed inside the positioning clamp, the arc-shaped anti-slip plate in the anti-slip limiting component can tightly fit the outer wall of the air conditioning hose under the action of the telescopic rod and spring, increasing the friction force and effectively preventing the air conditioning hose from shifting during use, thus avoiding unstable connection caused by displacement.

[0038] like Figure 1-5 As shown, this embodiment proposes a bend-resistant protection structure for hoses in refrigeration and air conditioning equipment piping fittings, including a first positioning clamp 1 and a second positioning clamp 2 located above the first positioning clamp 1, and also includes...

[0039] A spiral spring 3 is disposed between the first positioning clamp 1 and the second positioning clamp 2, and is used to wrap around the outer wall of the air conditioning hose to prevent the air conditioning hose from bending.

[0040] The first docking component 4 is installed at the connection between the first positioning hoop 1 and the bottom end of the spiral spring 3, and is used to connect the bottom end of the spiral spring 3 to the first positioning hoop 1.

[0041] The second docking component 5 is installed at the connection between the second positioning clamp 2 and the top of the spiral spring 3, and is used to connect the top of the spiral spring 3 to the second positioning clamp 2.

[0042] Anti-slip limiting components 6 are evenly distributed on the inner sidewalls of the first positioning clamp 1 and the second positioning clamp 2 to prevent the air conditioning hose from shifting.

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, the first docking assembly 4 further includes an annular seat 401 fixedly installed on the outer wall of the first positioning hoop 1. The groove wall of the annular seat 401 is provided with a threaded groove. The bottom end of the spiral spring 3 is rotatably connected to a fixing rod 402. A gripping handle 403 is fixedly installed on the outer wall of the upper section of the fixing rod 402. The outer wall of the fixing rod 402 near the annular seat 401 is fixedly provided with uniformly distributed external threads. The threaded section of the fixing rod 402 is threadedly connected to the groove wall of the annular seat 401, which facilitates fixing the bottom end of the spiral spring 3 to the first positioning hoop 1.

[0044] like Figure 4 As shown, in a preferred embodiment, based on the above method, the second docking assembly 5 is further characterized in that, except that the annular seat 401 in the second docking assembly 5 is fixedly installed on the outer wall of the second positioning hoop 2, the rest of the structure of the second docking assembly 5 is the same as that of the first docking assembly 4, and the first docking assembly 4 and the second docking assembly 5 are arranged opposite to each other, so as to facilitate fixing the top end of the spiral spring 3 on the second positioning hoop 2.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the first positioning clamp 1 further includes symmetrically arranged arc-shaped plates 101, the junction of the two sets of arc-shaped plates 101 is rotatably connected, the other ends of the two sets of arc-shaped plates 101 are connected by fixing bolts 102, and an arc-shaped groove 103 is opened on the inner side wall of any arc-shaped plate 101 to adapt to air conditioning hoses of different diameters, thereby improving the applicability of the first positioning clamp 1.

[0046] like Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the anti-slip limiting component 6 further includes a telescopic rod 601 fixedly installed on the wall of the arc-shaped groove 103, an arc-shaped anti-slip plate 602 fixedly installed on the telescopic end of the telescopic rod 601, and a spring 603 fixedly disposed between the wall of the arc-shaped groove 103 and the arc-shaped anti-slip plate 602 and sleeved on the outer wall of the telescopic rod 601, which can prevent the air conditioning hose from shifting during use.

[0047] like Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, a rubber layer is further provided at one end of the arc-shaped anti-slip plate 602 near the air conditioning hose, and the rubber layer on the arc-shaped anti-slip plate 602 is in full contact with the outer wall of the air conditioning hose, increasing the friction between the two.

[0048] Specifically, when using the anti-bending protection structure for the hose of this refrigeration and air conditioning equipment pipe fittings: open the two sets of arc plates 101 around the position where the air conditioning hose needs to be fixed, so that the rotation connection of the two sets of arc plates 101 naturally unfolds. Put the two sets of arc plates 101 on the interface between the air conditioning hose and the metal pipe, so that the air conditioning hose is located in the circular space formed between the two sets of arc plates 101. Connect the other end of the two sets of arc plates 101 with the fixing bolts 102, tighten the fixing bolts 102, so that the first positioning clamp 1 is firmly fixed at the interface between the air conditioning hose and the metal pipe.

[0049] Following the same operating method as the first positioning clamp 1, open the two sets of arc plates 101 of the second positioning clamp 2 and put them on the interface between the other end of the air conditioning hose and the metal pipe. Use fixing bolts 102 to connect and tighten the two sets of arc plates 101 of the second positioning clamp 2 to ensure that there is enough space between the first positioning clamp 1 and the second positioning clamp 2 to accommodate the spiral spring 3.

[0050] Hold the bottom end of the spiral spring 3 and align the threaded end of the fixed rod 402 connected to the bottom end with the threaded groove of the annular seat 401 on the outer wall of the first positioning hoop 1.

[0051] Hold the handle 403 on the fixing rod 402 and rotate the handle 403 clockwise so that the threaded section of the fixing rod 402 is gradually screwed into the groove thread of the annular seat 401 until the fixing rod 402 is fully tightened. Fix the bottom end of the spiral spring 3 to the first positioning clamp 1. At this time, evenly wrap the spiral spring 3 around the outer wall of the air conditioning hose.

[0052] Similarly, hold the top of the spiral spring 3 and align the threaded end of the fixed rod 402 connected to the top with the threaded groove of the annular seat 401 on the outer wall of the second positioning hoop 2.

[0053] Hold the handle 403 on the fixing rod 402 and rotate the handle 403 clockwise so that the threaded section of the fixing rod 402 is gradually screwed into the groove thread of the annular seat 401 until the fixing rod 402 is fully tightened. Fix the top of the spiral spring 3 to the second positioning clamp 2. At this time, the spiral spring 3 is tightly wrapped around the outer wall of the air conditioning hose, which provides support and protection for the air conditioning hose, prevents the air conditioning hose from bending during use, and ensures the normal flow of the medium inside the air conditioning hose.

[0054] When the helical spring 3 needs to be replaced, the worker holds the handle 403 of the fixing rod 402 on the first positioning clamp 1 and rotates the handle 403 counterclockwise so that the threaded section of the fixing rod 402 is unscrewed from the groove thread of the annular seat 401, thereby removing the entire helical spring 3 from the air conditioning hose, which facilitates the quick installation and removal of the helical spring 3.

[0055] When the first positioning clamp 1 and the second positioning clamp 2 are installed, at the same time, the telescopic rod 601 in the anti-slip limiting assembly 6 is in close contact with the outer wall of the air conditioning hose under the elastic force of the spring 603. The rubber layer on the arc-shaped anti-slip plate 602 is in full contact with the outer wall of the air conditioning hose, which increases the friction between the two and effectively prevents the air conditioning hose from shifting during use.

[0056] All technical features in this embodiment can be freely combined according to actual needs.

[0057] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
