Description
Technical Field
[0001] This utility model belongs to the field of gas pipeline technology, and in particular relates to a U-shaped pipe assembly for stoves. Background Technology
[0002] In gas stoves, U-shaped gas pipes are commonly used for transporting gases such as liquefied petroleum gas, manufactured gas, and natural gas.
[0003] U-shaped pipes consist of straight sections and bends. During use, they have the following defects: when the straight section shakes or shifts, it will pull on the bend, causing deformation of the bend. This leads to local changes in the inner diameter of the bend and obstruction of airflow, which in turn affects the smoothness and safety of gas transmission.
[0004] Existing patent documents disclose "a gas transmission pipe assembly" (publication number: CN218543485U), whose pipe body is a U-shaped pipe body, and it also has the above-mentioned technical problems. Summary of the Invention
[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a U-shaped tube assembly for stoves, which has high structural stability, is not easy to deform in the bend section, has a long service life and high safety.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A U-shaped tube assembly for cooktops includes a U-shaped tube body. The U-shaped tube body is characterized by a support base, which includes an L-shaped support arm, a first tube sleeve, a support arm, and a second tube sleeve. The L-shaped support arm connects to the support arm. The first tube sleeve is located at both ends of the L-shaped support arm, and the second tube sleeve is located at one end of the support arm. The first tube sleeve is fitted onto the straight section of the U-shaped tube body, and the second tube sleeve is fitted onto the curved section of the U-shaped tube body. This U-shaped tube assembly exhibits high structural stability, the curved section is less prone to deformation, has a long service life, and high safety.
[0008] Furthermore, the U-shaped tube body is equipped with a clamping seat, which includes a base block, a U-shaped support block, a pressure plate, and end screws. The U-shaped support block is located on the base block and has a positioning groove corresponding to the pressure plate. The pressure plate has a first through hole corresponding to the end screws, and the base block has a second through hole corresponding to the end screws. During installation, the straight section of the U-shaped tube body is first inserted into the U-shaped support block, then the pressure plate is inserted into the positioning groove, and then the end screws are passed through the first and second through holes in sequence and connected to the pre-set threaded holes on the bottom shell of the stove. This fixes the clamping seat to the bottom shell of the stove without the need to use screws to fix the base block separately. The fixation is done in one step, saving effort and making it convenient. The end of the end screw presses down on the pressure plate, causing the pressure plate to press down on the U-shaped tube body. The pressure plate, together with the U-shaped support block, clamps the straight section of the tube body, restricting the free movement of the U-shaped tube body. The clamping seat provides support to the U-shaped tube body, improving its stability.
[0009] Furthermore, a rubber pad is provided on the bottom surface of the pressure plate. The rubber pad is in close contact with the surface of the U-shaped tube, which buffers the squeezing effect and prevents indentations from forming on the surface of the U-shaped tube.
[0010] Furthermore, the end of the U-shaped pipe is equipped with a pipe interface, and the inner wall of the pipe interface has internal threads and a sealing ring. The inner diameter of the sealing ring is smaller than the inner diameter of the pipe interface. The pipe interface is screwed and fixed to the external gas pipeline. When the external gas pipeline comes into contact with the sealing ring, it indicates that the connection is in place. The sealing ring covers the gap between the inner wall of the pipe interface and the outer wall of the external gas pipeline, which can prevent gas leakage.
[0011] Furthermore, an annular groove for embedding a sealing ring is provided on the inner wall of the pipe interface, which facilitates the installation and replacement of the sealing ring, making it flexible and convenient.
[0012] Furthermore, a connecting arm is provided between the two sections of the support arm and the L-shaped support arm. The support arm connects the two sections of the L-shaped support arm, realizing indirect support of the straight pipe section for the curved pipe section. The two sections of the L-shaped support arm can simultaneously provide support to the curved pipe section of the U-shaped pipe body through the support arm, thereby limiting the deformation of the curved pipe section of the U-shaped pipe body.
[0013] Furthermore, the support arm connects to the corner of the L-shaped support arm, and the support arm connects the two sections of the L-shaped support arm, realizing the indirect support of the straight pipe section for the curved pipe section. The two sections of the L-shaped support arm can simultaneously provide support to the curved pipe section of the U-shaped pipe body through the support arm, thereby limiting the deformation of the curved pipe section of the U-shaped pipe body, and also improving the structural strength at the corner of the L-shaped support arm, thereby improving the structural strength of the support base, and the structure of the support arm is simpler.
[0014] Furthermore, the L-shaped support arm protrudes downwards to form a pillar, and a mounting block is provided at the bottom of the pillar. The mounting block has a fixing through hole. Screws are driven into the fixing through hole to fix the support base to the pre-threaded hole on the bottom shell of the stove. The bottom shell of the stove provides support to the U-shaped tube body through the support base, which improves the stability of the U-shaped tube body.
[0015] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:
[0016] 1. The L-shaped support arm connects two adjacent straight pipe sections simultaneously, forming a mutual restraint relationship, which restricts the free swaying of any straight pipe section, thereby improving the structural stability of the U-shaped pipe body; the support arm connects the two sections of the L-shaped support arm, realizing the indirect support of the straight pipe section for the curved pipe section. The two sections of the L-shaped support arm can simultaneously provide support to the curved pipe section through the support arm, thereby restricting the deformation of the curved pipe section.
[0017] 2. When installing the pipe clamp, first insert the straight pipe section into the U-shaped support block, then insert the pressure plate into the positioning groove, and then pass the end screw through the first and second through holes in sequence, and connect it with the preset threaded hole on the bottom shell of the stove to fix the pipe clamp onto the bottom shell of the stove. There is no need to use screws to fix the bottom block separately. Fixing is done in one step, saving effort and convenience. The end of the end screw presses down on the pressure plate, so that the pressure plate presses down on the U-shaped pipe body. The pressure plate, together with the U-shaped support block, clamps the straight pipe section and restricts the free shaking of the U-shaped pipe body. The pipe clamp provides support to the U-shaped pipe body and improves the stability of the U-shaped pipe body. Attached Figure Description

[0028] The U-shaped pipe body is provided with a support base 3, which includes an L-shaped support arm 4, a first pipe sleeve 5, a support arm 6, and a second pipe sleeve 7. The first pipe sleeve 5 is located at both ends of the L-shaped support arm 4 and is fitted onto the straight pipe section 1. The L-shaped support arm 4 connects two adjacent straight pipe sections 1, forming a mutual restraint relationship, which restricts the free swaying of any straight pipe section 1, thereby improving the structural stability of the U-shaped pipe body. The second pipe sleeve 7 is located at one end of the support arm 6 and is fitted onto the bent pipe section 2. There is a connecting arm 8 between the support arm 6 and the two sections of the L-shaped support arm 4. The support arm 6 connects the two sections of the L-shaped support arm 4, realizing that the straight pipe section 1 indirectly supports the bent pipe section 2. The two sections of the L-shaped support arm 4 can simultaneously provide support to the bent pipe section 2 through the support arm 6, thereby restricting the deformation of the bent pipe section 2.
[0029] The L-shaped support arm 4 protrudes downward to form a support column 9. The bottom of the support column 9 is provided with a mounting block 10, and the mounting block 10 is provided with a fixing through hole 11. Screws are driven into the fixing through hole 11 to fix the support base 3 to the preset threaded hole on the bottom shell of the stove.

[0031] During installation, first insert the straight pipe section 1 into the U-shaped support block 14, then insert the pressure plate 15 into the positioning groove 17, and then pass the end screw 16 through the first through hole 18 and the second through hole 19 in sequence, and connect it with the preset threaded hole on the bottom shell of the stove to fix the pipe clamp 12 on the bottom shell of the stove. There is no need to use screws to fix the bottom block 13 separately. The fixation is done in one step, saving effort and convenience. The end of the end screw 16 presses down on the pressure plate 15, so that the pressure plate 15 presses down on the straight pipe section 1. The pressure plate 15, together with the U-shaped support block 14, clamps the straight pipe section 1, restricting the free shaking of the straight pipe section 1. The pipe clamp 12 provides support to the U-shaped pipe body, improving the stability of the U-shaped pipe body.
[0032] A rubber pad 20 is bonded to the bottom surface of the pressure plate 15. The rubber pad 20 is in close contact with the surface of the straight pipe section 1, which buffers the squeezing effect and prevents indentations from forming on the surface of the straight pipe section 1.
[0033] The end of the straight pipe section 1 is provided with a pipe interface 21. The inner wall of the pipe interface 21 is provided with an internal thread and a sealing ring 22.
