Description

Technical Field

[0001] This utility model relates to the field of stainless steel sleeve technology for connection and fixation, and in particular to a stainless steel sleeve that is convenient for connection and fixation. Background Technology

[0002] In fields such as industrial pipeline installation, municipal water supply and drainage, and mechanical fluid transmission, the stability, sealing performance, and ease of operation of pipeline connections are core requirements. Traditional pipeline connections often use flange connections, threaded tightening, or welding, which have significant limitations: flange connections require multiple bolts, which need to be tightened one by one during installation, which is time-consuming and labor-intensive, and difficult to operate in confined spaces; threaded connections require high precision in the machining of the pipe ends, and are prone to loosening due to vibration after long-term use, resulting in a decrease in sealing performance; welding, although providing a strong connection, requires professional welders, resulting in low construction efficiency, and high-temperature welding can damage the stability of the pipe material, making disassembly difficult during later maintenance; in addition, existing connection devices generally lack the ability to adapt to different pipe diameters, and the sealing structure is simple, making them prone to leakage when fluid pressure fluctuates or temperature changes, which makes it difficult to meet the needs of modern engineering for efficient, reliable, and flexible connections.

[0003] Existing devices rely on bolts or welding to fasten pipes one by one. This not only requires repeated adjustments and alignment during installation, which consumes a lot of manpower and time, but is also extremely inconvenient, especially in batch connections or in confined spaces. Furthermore, uneven stress during bolt tightening can lead to loosening of the connection. In addition, there is a lack of sealing and buffering structures such as rubber rings and multiple sets of clamping blocks. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stainless steel sleeve that is easy to connect and fix.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stainless steel sleeve for easy connection and fixation includes a hollow circular plate. A connecting pipe is fixedly connected inside the hollow circular plate. Four fixing rings are fixedly connected around the connecting pipe. Four rubber rings are fixedly connected around the connecting pipe. Connecting cylinders are fixedly connected to both sides of the hollow circular plate. Locking mechanisms are fixedly connected to the opposite outer sides of the connecting cylinders.

[0007] As a further embodiment of this utility model: an adjusting rod is fixedly connected to one side of each of the two locking mechanisms, and a limiting ring is fixedly connected to the opposite outer side of each of the two locking mechanisms. Pipeline 1 and pipeline 2 are movably connected inside the connecting cylinder, the locking mechanism and the limiting ring, and pipeline 1 and pipeline 2 are movably connected around the fixed ring, the rubber ring and the connecting pipe.

[0008] As a further embodiment of this utility model: the locking mechanism includes a clamping block, a moving block, a small arc plate, a large arc plate, a round rod, a driving gear, a transmission gear, and a circular slide rail, and the transmission gear is movably connected to one side of the connecting cylinder.

[0009] As a further embodiment of this utility model: the circular slide rail is fixedly connected to one side of the transmission gear, three moving blocks are movably connected to one side of the circular slide rail, and a slider is provided on the side of the moving blocks near the circular slide rail. The three clamping blocks are respectively fixedly connected to the opposite inner sides of the three moving blocks.

[0010] As a further embodiment of this utility model: the six clamping blocks are movably connected to the four sides of pipe one and pipe two respectively, the three small arc-shaped plates are fixedly connected to one side of the connecting cylinder respectively, and the three large arc-shaped plates are fixedly connected to one side of the connecting cylinder respectively.

[0011] As a further embodiment of this utility model: the three movable blocks are respectively movably connected to the relative inner sides of the three small arc-shaped plates and the three large arc-shaped plates, and the limiting ring is fixedly connected to one side of the three small arc-shaped plates and the three large arc-shaped plates.

[0012] As a further embodiment of this utility model: the round rod is movably connected to one side of a small arc-shaped plate, and the round rod passes through a large arc-shaped plate, and the adjusting rod is fixedly connected to one side of the round rod, the driving gear is fixedly connected to the four sides of the round rod, and the driving gear and the transmission gear mesh with each other.

[0013] Compared with the prior art, this utility model provides a stainless steel sleeve that is easy to connect and fix, and has the following beneficial effects:

[0014] 1. This stainless steel sleeve facilitates connection and fixation. By inserting pipe one and pipe two into the connecting cylinder, locking mechanism and limiting ring respectively, the connecting ends of pipe one and pipe two are fitted onto the outside of the connecting pipe, and the fixing ring and rubber ring are located inside pipe one and pipe two, thus quickly completing the initial connection of the pipes. This makes the pipe assembly operation more efficient and reduces labor and time costs.

[0015] 2. This stainless steel sleeve, which is easy to connect and fix, controls two adjusting rods. Rotating the adjusting rods causes the locking mechanism to operate, fixing and locking pipe one and pipe two around their perimeter. As a result, the operation is simpler and pipe one and pipe two can be fixed and locked quickly, greatly shortening the installation time.

[0016] 3. This stainless steel sleeve, which facilitates connection and fixation, rotates an adjusting rod, which in turn rotates a circular rod. The driving gear on the circular rod rotates accordingly. Because the driving gear meshes with the transmission gear, the rotation of the transmission gear drives the moving block along the trajectory of the small arc plate and the large arc plate via a circular slide rail. The moving block drives the clamping block to approach and clamp the pipes one and two. Through gear transmission, the rotation of the adjusting rod is converted into the clamping action of the clamping block. Thus, the pipes one and two are precisely and stably locked and fixed, ensuring a firm pipe connection, improving connection reliability and sealing performance. With the help of rubber rings, the leak-proof and buffering performance of the connection is also enhanced, ensuring the stable operation of the pipeline system.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] A stainless steel sleeve that is easy to connect and fix, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a hollow circular plate 3, with a connecting pipe 10 fixedly connected inside the hollow circular plate 3. Four fixing rings 8 are fixedly connected around the connecting pipe 10, and four rubber rings 9 are fixedly connected around the connecting pipe 10. Connecting cylinders 4 are fixedly connected to both sides of the hollow circular plate 3, and locking mechanisms 2 are fixedly connected to the opposite outer sides of the connecting cylinders 4.

[0028] Adjusting rods 5 are fixedly connected to one side of each of the two locking mechanisms 2. Limiting rings 1 are fixedly connected to the opposite outer sides of the two locking mechanisms 2. Pipe 6 and pipe 7 are movably connected inside the connecting cylinder 4, the locking mechanism 2 and the limiting ring 1. Pipe 6 and pipe 7 are movably connected around the fixing ring 8, the rubber ring 9 and the connecting pipe 10.

[0029] During operation, pipe 6 and pipe 7 are inserted into the connecting cylinder 4, locking mechanism 2, and limiting ring 1 respectively, so that the connecting ends of pipe 6 and pipe 7 are fitted onto the outside of the connecting pipe 10. The fixing ring 8 and rubber ring 9 are positioned inside pipe 6 and pipe 7, quickly completing the initial connection of the pipes. Then, by controlling the two adjusting rods 5, rotating the adjusting rods 5 causes the locking mechanism 2 to operate, fixing and locking pipe 6 and pipe 7 around its perimeter. This makes the operation simpler and allows for quick fixing and locking of pipe 6 and pipe 7, significantly shortening the installation time. It is especially suitable for batch pipe connections or construction space-constrained scenarios, making pipe assembly operations more efficient and reducing labor and time costs.

[0030] To secure the connection between pipe 6 and pipe 7, such as... Figure 4 and Figure 5 As shown, the locking mechanism 2 includes a clamping block 201, a moving block 202, a small arc plate 203, a large arc plate 204, a round rod 205, a driving gear 206, a transmission gear 207, and a circular slide rail 208, with the transmission gear 207 movably connected to one side of the connecting cylinder 4.

[0031] The circular slide rail 208 is fixedly connected to one side of the transmission gear 207, and three movable blocks 202 are movably connected to one side of the circular slide rail 208. The movable blocks 202 have sliders on the side near the circular slide rail 208, and three clamping blocks 201 are fixedly connected to the opposite inner sides of the three movable blocks 202.

[0032] Furthermore, six clamping blocks 201 are movably connected to the four sides of pipe 6 and pipe 7, three small arc plates 203 are fixedly connected to one side of the connecting cylinder 4, and three large arc plates 204 are fixedly connected to one side of the connecting cylinder 4.

[0033] Furthermore, the three movable blocks 202 are respectively movably connected to the relative inner sides of the three small arc plates 203 and the three large arc plates 204, and the limiting ring 1 is fixedly connected to one side of the three small arc plates 203 and the three large arc plates 204.

[0034] The round rod 205 is movably connected to one side of a small arc plate 203, and the round rod 205 passes through a large arc plate 204. The adjusting rod 5 is fixedly connected to one side of the round rod 205. The drive gear 206 is fixedly connected to the four sides of the round rod 205, and the drive gear 206 and the transmission gear 207 mesh with each other.

[0035] During operation, rotating the adjusting rod 5 causes the round rod 205 to rotate, and the drive gear 206 on the round rod 205 rotates accordingly. Since the drive gear 206 meshes with the transmission gear 207, the rotation of the transmission gear 207 drives the moving block 202 to move along the trajectory of the small arc plate 203 and the large arc plate 204 through the circular slide rail 208. The moving block 202 drives the clamping block 201 to approach and clamp the pipe 6 and the pipe 7. Through gear transmission, the rotation of the adjusting rod 5 is converted into the clamping action of the clamping block 201. Thus, the pipe 6 and the pipe 7 are precisely and stably locked and fixed, making the pipe connection firm, improving the connection reliability and sealing performance. With the help of rubber rings 9, the leak-proof and buffering performance of the connection is also enhanced, ensuring the stable operation of the pipeline system.

[0036] Working principle: By inserting pipe 6 and pipe 7 into the connecting cylinder 4, locking mechanism 2 and limiting ring 1 respectively, the connecting ends of pipe 6 and pipe 7 are respectively fitted onto the outside of connecting pipe 10, and the fixing ring 8 and rubber ring 9 are located inside pipe 6 and pipe 7, thus quickly completing the initial connection of the pipes.

[0037] Then, by controlling the two adjusting rods 5, rotating the adjusting rods 5 causes the round rod 205 to rotate, and the drive gear 206 on the round rod 205 rotates accordingly. Since the drive gear 206 meshes with the transmission gear 207, the transmission gear 207 rotates and drives the moving block 202 to move along the trajectory of the small arc plate 203 and the large arc plate 204 through the circular slide rail 208. The moving block 202 drives the clamping block 201 to approach and clamp the pipe 6 and the pipe 7. Through gear transmission, the rotation of the adjusting rod 5 is converted into the clamping action of the clamping block 201, thereby fixing and locking the pipe 6 and the pipe 7 around.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
