Description

Technical Field

[0001] This invention relates to the field of radiators, and more particularly to a wall-mounted radiator that is easy to install. Background Technology

[0002] Wall-mounted radiators are typically installed during the construction phase or when improving the environment. They usually heat the room by circulating hot water into the radiator. Therefore, the installation location of the wall-mounted radiator needs to be coordinated with the heating pipe system.

[0003] In existing technologies, because radiators require hot water for heating, wall-mounted radiators are typically installed before the heating pipes are laid. However, during radiator use, when it's necessary to disassemble the radiator for cleaning or maintenance, the existing water supply pipes cannot be axially adjusted relative to the radiator's inlet / outlet. Currently, this problem is usually solved by incorporating a metal corrugated pipe with axial expansion capability. However, corrugated pipes are not only expensive but also require a long enough length, significantly increasing space requirements. Furthermore, the bending of the corrugated pipe greatly reduces its ability to withstand water pressure. Those skilled in the art have conducted extensive research on this issue. For example, patent application number "202110586515.4," entitled "A Micro-expansion Mechanism for Water Supply Equipment and Its Usage Method," describes adding a detachable telescopic flange in the middle of the pipe to achieve micro-expansion. While this method achieves micro-expansion, the amount of expansion is very limited, and to ensure sealing, a large number of bolts are used for fixing, making disassembly and assembly very inconvenient. Therefore, how to design a wall-mounted radiator that is easy to install, while allowing for the expansion and contraction adjustment of the radiator's inlet / outlet, and ensuring a tight seal between the radiator and the pipes, has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of this invention is to overcome the shortcomings of the prior art and provide a wall-mounted radiator that is easy to install, which can facilitate the sealing of the connection between the radiator and the pipe while allowing the inlet / outlet of the radiator to be extended and adjusted.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0006] A wall-mounted radiator that is easy to install includes a radiator body for wall mounting, wherein a telescopic tube is connected to the water inlet / outlet of the radiator body.

[0007] The telescopic tube section includes a first telescopic tube and a second telescopic tube. The first telescopic tube has a telescopic cavity inside. The second telescopic tube is sleeved with the first telescopic tube. A sealing groove is provided at the connection between the first telescopic tube and the second telescopic tube. A second sealing ring is provided inside the sealing groove for sealing the gap between the first telescopic tube and the second telescopic tube.

[0008] It also includes a sleeve, one end of which is used to push the second sealing ring, and the other end of which is connected to a first sealing ring. The first sealing ring and the sleeve divide the telescopic cavity into a first inner cavity and a second inner cavity, and the second inner cavity is connected to the sealing groove.

[0009] Compared with the prior art, the advantages of the present invention are:

[0010] When using this invention, if it is necessary to connect the pipe to the radiator body, the first telescopic pipe is connected to the radiator body, and the second telescopic pipe is moved to adjust the length of the pipe according to the required pipe length, and the free end of the second telescopic pipe is connected to the pipe.

[0011] After the connection is completed, water is introduced into the interior of the second telescopic tube. After the water fills the radiator, the water flows into the interior of the first inner cavity through the connecting hole. Due to the water pressure, the sleeve drives the first sealing ring to move. The sleeve pushes the second sealing ring to compress and deform, pressing against the outer wall of the second telescopic tube and the inner wall of the sealing groove to seal the gap between the first and second telescopic tubes.

[0012] Through the above structural design, not only is a large-scale telescopic channel achieved, but the water pressure inside the pipeline is also used to pressurize the second sealing ring between the telescopic pipes, thereby improving the sealing capacity between the pipeline and the radiator as the water pressure increases.

[0013] Preferably, the inner wall of the second inner cavity is provided with a sealing part for pressing and sealing against the first sealing ring, and the sealing part is an inner conical surface with a radius that gradually decreases from the sleeve to the second sealing ring.

[0014] Preferably, the interior of the first inner cavity is provided with a spring for driving the first sealing ring to press against the sealing part.

[0015] Preferably, the first inner cavity is provided with an abutment seat and an adjustment component for adjusting the axial position of the abutment seat, and the two ends of the spring abut against the abutment seat and the sleeve, respectively.

[0016] Preferably, the adjusting component is threaded, the abutment seat is threadedly connected to the inner wall of the first inner cavity, and the second telescopic tube is splinedly connected to the abutment seat.

[0017] Preferably, one of the abutment seat and the second telescopic tube has a connecting hole, and the free end of the first telescopic tube is connected to the first inner cavity through the connecting hole.

[0018] Preferably, the first telescopic tube has an exhaust hole, and the second inner cavity is connected to the outside through the exhaust hole.

[0019] Preferably, a locking assembly for preventing relative rotation between the first telescopic tube and the second telescopic tube is provided.

[0020] Preferably, the locking assembly includes a locking spring, one end of which is fixedly connected to the first telescopic tube. The thickness of the locking spring gradually increases along the direction from the connection between the locking spring and the first telescopic tube towards the free end of the locking spring. Multiple locking springs are arranged in a ring array outside the second telescopic tube, and locking nuts are threadedly connected to the outer side of the ring array of locking springs.

[0021] Preferably, the inner wall of the sealing groove is an inner conical surface with a radius that gradually decreases from the sleeve towards the second sealing ring. Attached Figure Description

Detailed Implementation

[0028] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and mastered.

[0029] Example 1:

[0030] Reference Figures 1 to 3 As shown, this embodiment provides a wall-mounted radiator that is easy to install, including a radiator body 10 for wall mounting, wherein a telescopic tube is connected to the water inlet / outlet of the radiator body 10.

[0031] The telescopic tube section includes a first telescopic tube 20 and a second telescopic tube 40. The first telescopic tube 20 has a telescopic cavity 30 inside. One end of the second telescopic tube 40 extends into the telescopic cavity 30 and is sleeved with the first telescopic tube 20. A sealing groove 54 is provided at the connection between the first telescopic tube 20 and the second telescopic tube 40. A second sealing ring 55 is provided inside the sealing groove 54 for sealing the gap between the first telescopic tube 20 and the second telescopic tube 40.

[0032] It also includes a sleeve 53, one end of which is used to push the second sealing ring 55, and the other end of which is connected to a first sealing ring 51. The first sealing ring 51 and the sleeve 53 divide the telescopic cavity 30 into a first inner cavity 31 and a second inner cavity 32. The second inner cavity 32 is connected to the sealing circular groove 54. The inner wall of the second inner cavity 32 is provided with a sealing part 52 for pressing and sealing against the first sealing ring 51. The sealing part 52 is an inner conical surface with a radius that gradually decreases from the sleeve 53 to the second sealing ring 55.

[0033] When in use: When it is necessary to connect the pipe to the radiator body 10, the first telescopic pipe 20 is connected to the radiator body 10, the second telescopic pipe 40 is moved according to the required pipe length to adjust the pipe length, and the free end of the second telescopic pipe 40 is connected to the pipe.

[0034] After connection, water is introduced into the second telescopic tube 40. After the water fills the radiator, it flows into the first inner cavity 31 through the connecting hole 42. Due to the water pressure, the sleeve 53 drives the first sealing ring 51 to move. The sleeve 53 pushes the second sealing ring 55 to compress and deform, pressing against the outer wall of the second telescopic tube 40 and the inner wall of the sealing groove 54 to seal the gap between the first telescopic tube 20 and the second telescopic tube 40. At the same time, the sleeve 53 drives the first sealing ring 51 to move and press against the sealing part 52. Due to the inner conical surface of the sealing part 52, the compression and deformation of the first sealing ring 51 improves the sealing ability between the abutment seat 43 and the sealing part 52, preventing the first sealing ring 51 from breaking the seal between the sleeve 53 and the sealing part 52 due to excessive water pressure. (It is worth noting that: because the water pressure pushes the sleeve 53 and the second sealing ring 55 to seal the first telescopic tube 20 and the second telescopic tube 40, it will increase the friction between the second sealing ring 55 and the second telescopic tube 40, thereby increasing the sliding resistance between them; if the second sealing ring 55 is squeezed to seal the connection between the first telescopic tube 20 and the second telescopic tube 40 before adjusting the length of the telescopic tube section, it will cause poor sliding between them and damage the second sealing ring 55 due to friction, resulting in sluggish sealing.)

[0035] Combination Figure 3 As shown, in order to ensure that the gap between the first telescopic tube 20 and the second telescopic tube 40 is sealed when there is no water pressure inside the first inner cavity 31, the first inner cavity 31 is provided with a spring 44 for driving the first sealing ring 51 to press against the sealing part 52. The two ends of the spring 44 press against the inner wall of the sleeve 53 and the first telescopic tube 20 respectively, and the sleeve 53 provides a certain pre-pressure to the second sealing ring 55.

[0036] Combination Figure 3 As shown, in order to adjust the pre-pressure provided by the sleeve 53 to the second sealing ring 55, the first inner cavity 31 is provided with an abutment seat 43. The abutment seat 43 is connected with a thread for adjusting the axial position of the abutment seat 43 inside the first inner cavity 31. The two ends of the spring 44 abut against the abutment seat 43 and the sleeve 53 respectively. The abutment seat 43 is connected to the inner wall of the first inner cavity 31 by a thread. The second telescopic tube 40 is splinedly connected to the abutment seat 43. A connecting hole 42 is opened on the spline of the second telescopic tube 40. The free end of the first telescopic tube 20 is connected to the first inner cavity 31 through the connecting hole 42.

[0037] In use: By rotating the second telescopic tube 40, the abutment seat 43 is driven to rotate. The second telescopic tube 40 and the abutment seat 43 slide relative to each other. Due to the presence of the thread, the axial position of the abutment seat 43 relative to the first telescopic tube 20 changes, and the distance between the abutment seats 43 changes. The spring 44 is compressed or released part of the time, and the pressure of the spring 44 on the sleeve 53 changes accordingly. The degree of deformation of the sleeve 53 changes, thereby changing the degree of sealing between the first telescopic tube 20 and the second telescopic tube 40.

[0038] Combination Figure 3 and Figure 5 As shown, in order to facilitate the inspection of the sealing effect of the first sealing ring 51, the first telescopic tube 20 is provided with an exhaust hole 56, the second inner cavity 32 is connected to the outside through the exhaust hole 56, and the first telescopic tube 20 is also provided with a sealing cap for sealing the exhaust hole 56.

[0039] In use: If the sealing of the first sealing ring 51 fails, water inside the first inner cavity 31 will enter the second inner cavity 32 due to water pressure. The sealing cap can be opened periodically to observe whether there is water inside the second inner cavity 32, thereby determining whether the first sealing ring 51 is damaged.

[0040] Combination Figure 3 As shown, in order to improve the sealing performance of the second sealing ring 55 over the gap between the first telescopic tube 20 and the second telescopic tube 40, the inner wall of the sealing groove 54 is an inner conical surface with a gradually decreasing radius from the sleeve 53 towards the second sealing ring 55. When the sleeve 53 presses against the second sealing ring 55 and causes the second sealing ring 55 to deform, the gap between the inner wall of the sealing groove 54 and the outer wall of the second telescopic tube 40 gradually decreases. As the second sealing ring 55 moves, the degree of deformation of the second sealing ring 55 increases, and the pressing force of the second sealing ring 55 on the second telescopic tube 40 gradually increases, thereby improving the sealing performance between the first telescopic tube 20 and the second telescopic tube 40.

[0041] Example 2:

[0042] The difference between this embodiment and Embodiment 1 lies in the driving method of the abutment seat 43.

[0043] In this embodiment, the driving method of the abutment seat 43 is changed to linear motor drive. By driving the movement of the abutment seat 43 through the linear motor, the compression of the spring 44 is changed, thereby adjusting the pre-pressure of the second sealing ring 55.

[0044] Example 3:

[0045] The difference between this embodiment and Embodiment 1 / 2 is that a locking component is added to prevent the relative rotation of the first telescopic tube 20 and the second telescopic tube 40.

[0046] Combination Figure 2 and Figure 3 As shown, to prevent the second telescopic tube 40 from rotating under external force during connection or use, thereby causing the second telescopic tube 40 to rub against the second sealing ring 55 and affecting the sealing performance of the second sealing ring 55, a locking assembly for locking the relative rotation of the first telescopic tube 20 and the second telescopic tube 40 is provided. The locking assembly includes a locking spring 21, one end of which is fixedly connected to the first telescopic tube 20. The thickness of the locking spring 21 gradually increases along the direction from the connection between the locking spring 21 and the first telescopic tube 20 towards the free end of the locking spring 21. Multiple locking springs 21 are arranged in a ring array on the outer side of the second telescopic tube 40, and locking nuts 22 are threadedly connected to the outer side of the ring array of locking springs 21.

[0047] In use: After the second telescopic tube 40 is connected to the pipe, the thickness of the locking spring 21 gradually increases along the direction from the connection between the locking spring 21 and the first telescopic tube 20 to the free end of the locking spring 21. By rotating the locking nut 22, the locking nut 22 moves axially in the locking spring 21, thereby causing the multiple locking springs 21 in the annular array to clamp the second telescopic tube 40, thus locking the second telescopic tube 40.

[0048] The above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
