Description

Technical Field

[0001] The utility model relates to the technical field of water heating pipe products, in particular to a welded copper elbow set with a mounting bracket and closed ends. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. Usually, the fluid flows from the high pressure part of the pipeline to the low pressure part, and can also be transported by the fluid's own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices.

[0003] Due to space and technical limitations, most existing water pipe systems use straight pipes, and pipe joints are often used at the joints on different planes, which reduces the sealing of the pipes and makes them inconvenient to disassemble and assemble, thereby greatly increasing the cost. Especially in wall-mounted boilers, electric water heaters and other electrical appliances, the internal space is small and the pipe diameter is also very small. There are many inconveniences in using straight pipes, and straight pipe waterways will make the entire waterway system more narrow, long and complex.

[0004] As an example of the prior art, referring to the prior patent document CN211779593U, a bending pipe assembly of a water cooling system is disclosed, including an elbow or a multi-channel pipe joint, wherein at least one port of the elbow or the multi-channel pipe joint has an extension portion extending the corresponding channel, and the extension portion is inserted with a telescopic pipe that can move along its axial direction, and the joint between the telescopic pipe and the extension portion is watertight. The elbow or the multi-channel pipe joint is used as the main body, so there is no need to perform a pipe bending operation, and the situation of pipe blistering, too large or too small bending angle caused by the bending operation is avoided; at the same time, at least one port of the elbow or the multi-channel pipe joint is provided with an extension portion extending the corresponding channel, and the extension portion is inserted with a telescopic pipe that can move along the axial direction of the extension portion, and the telescopic length of the telescopic pipe can be adjusted according to the size requirements of the installation, so there is no need to perform a cutting operation, and the situation of excessive cutting is avoided, thereby preventing the scrapping caused by improper bending and cutting. It has universality and the installation process is very convenient.

[0005] In the above-mentioned prior art examples, combined with its text description and drawings, it can be inferred without a doubt that its bending pipe assembly adopts a multi-section split pipe assembly combination method, so there are many defects, such as: 1. There are many parts, which need to be formed and processed by multiple sets of molds respectively, and assembled in the later stage, so the processing technology is more complicated; 2. Sealing problems are prone to occur at the joints of multiple parts, that is, leakage is more likely to occur during later use; 3. Disassembly and maintenance are more difficult during later use; 4. At the turning point of the pipeline, a 90-degree right-angle turning method is adopted, so the resistance to the internal fluid is greater, which will reduce the flow rate; 5. It does not have a connection and reinforcement structure connected to the external support surface, and it is easy to fall off once it is impacted during use. Summary of the invention

[0006] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a welded copper elbow kit with a mounting bracket and closed ends.

[0043] Reference Figures 1 to 8A welded copper elbow kit with a mounting bracket and closed ends includes: a copper elbow body 1, which is composed of a closed straight pipe section 11, a bent pipe section 12 and an open straight pipe section 13; wherein the copper elbow body 1 is an integrally formed part, which is a copper pipe processed into a desired shape after passing through a bending die. It is worth mentioning that the bent pipe section 12 adopts an arc transition structure, which has an excellent fluid mechanics structure design on the basis of realizing a 90-degree turn of the flow channel, and can minimize the resistance to the fluid and accelerate the flow effect.

[0044] The mounting bracket 2 is sleeved on the closed straight pipe section 11 of the copper elbow body 1. The mounting bracket is provided with a plurality of fixing holes 21, and fasteners 212 are inserted into the fixing holes 21 to fix the mounting bracket 2 with the external support body 211.

By disposing the hinge block 43, the upper flange ring 41 and the lower flange ring 42 can rotate relative to each other to achieve the action of rotating to open and close.

[0053] Furthermore, the quick-release fastening assembly 44 includes a screw rod 441, an operating knob 442 fixed to the upper end of the screw rod 441, a fastening ball head 443 fixed to the upper flange ring 41 or the lower flange ring 42 and threadedly matched with the lower end of the screw rod 441, and a limiting rod 444; wherein the fastening ball head 443, the upper flange ring 41 and the lower flange ring 42 are provided with mutually aligned limiting holes 445, and the limiting rod 444 is passed through the limiting hole 445. When in use, firstly, the user can realize the unlocking or locking function of the quick-release fastening assembly 44 by plugging and pulling out the limiting rod 444; secondly, the relative position of the screw rod 441 and the fastening ball head 443 can be adjusted to adapt to the actual application requirements of different pipe sizes.

[0054] A more preferred configuration is that a sponge pad 446 is provided in the limiting hole 445, and the limiting rod 444 and the sponge pad 446 form an interference fit to prevent the limiting rod 444 from being separated from the limiting hole 445 during use. If disassembly is required, the user can manually use a tool to force (the force is greater than the static friction between the limiting rod 444 and the sponge pad 446) to push the limiting rod 444 away from the limiting hole 445.

[0055] It is worth mentioning that the limit hole 445 described in this embodiment includes an upper limit hole 4451 and a lower limit hole 4452, and the limit rod 444 can cooperate with any one of them to achieve different installation effects. Specifically: when the limit rod 444 cooperates with the lower limit hole 4452, the quick-release fastening assembly 44 is installed upright; when the limit rod 444 cooperates with the upper limit hole 4451, the quick-release fastening assembly 44 is installed inverted. Therefore, the copper bending tube kit in the utility model can be installed upright or inverted to meet the use requirements of different installation environments.

[0056] Embodiment 3

[0058] It is worth mentioning that the inner annular sealing section 52 has a straight inner wall 53, which extends to the front and rear sides to form a sealing wrapping section 54. First, the arrangement of the straight inner wall 53 allows the inner annular sealing section 52 to have a better contact effect with the welding area 31, prevents unevenness from occurring, and increases the contact area to a certain extent; second, the sealing wrapping section 54 further increases the contact area with the welding area 31 to ensure good sealing performance and prevent leakage.

[0059] It is worth noting that other technical solutions of the present invention belong to the prior art and will not be described in detail.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
