Description

Technical Field

[0001] The utility model relates to the technical field of mechanical connection, in particular to a high-density flange. Background Art

[0002] Flanges are commonly used connectors in the industrial field and are widely used in pipelines, containers, equipment, etc. Traditional flange connections usually require multiple steps, such as fixing bolts one by one, adjusting alignment, etc. One of the main advantages of high-density flange design is its significant improvement over traditional installation steps. In the traditional flange installation process, multiple steps are usually required, such as fixing bolts one by one, adjusting alignment, etc. These steps are often cumbersome and time-consuming. In addition, traditional flange connections sometimes have problems with loose connections due to factors such as materials, processes or use environment, which may cause leakage or equipment failure. These problems have brought many inconveniences and safety hazards to industrial production and applications. In order to solve the above problems, it is necessary to design a high-density flange to simplify the installation steps, improve installation efficiency, and enhance the firmness of the connection. Utility Model Content

[0003] The utility model provides a high-density flange, which solves the problems of complicated installation steps and unstable installation.

[0004] The technical solution of the utility model is as follows:

[0005] A high-density flange comprises a first flange, a fixed sleeve and an adapting sleeve, wherein a fixed block is installed on the outer wall of the first flange, a top block is installed on the top of the first flange, a slot is provided on the inner wall of the first flange, a fixed sleeve is installed on the outer wall of the top block, thread teeth are provided on the inner wall of the fixed sleeve, a fixed groove is provided on the top of the thread teeth, a second flange is installed on the bottom of the first flange, a sealing ring is installed on the outer wall of the second flange, sealing blocks are installed on both sides of the top of the outer wall of the sealing ring, and an adapting sleeve is installed on the bottom of the sealing ring.

[0006] Preferably, a card block is installed on the top of the sealing block, a slot is installed on the top of the card block, a telescopic rod is installed on the inner wall of the slot, and the card block can be inserted into the inner wall of the slot.

[0007] Preferably, a pressure spring is installed around the outer wall of the telescopic rod, and a clamping column is installed at one end of the telescopic rod. The pressure spring can drive the telescopic rod to extend or contract.

[0008] Preferably, the fixing groove is installed on the inner wall of the fixing sleeve, the diameter of the inner wall of the fixing groove is matched with the diameter of the fixing block, and the fixing groove allows the fixing sleeve to rotate along the outer wall of the first flange.

[0009] Preferably, the inner wall of the fixing sleeve is provided with a cavity, and the diameter of the fixing sleeve cavity is matched with the diameter of the first flange. The fixing sleeve is sleeved on the outer wall of the first flange, and the fixing sleeve and the first flange are not directly connected.

[0010] Preferably, one end of the adapter sleeve is provided with a thread, and the thread of the adapter sleeve is matched with the thread teeth, and when the fixed sleeve rotates, the thread teeth on the inner wall of the fixed sleeve will cause the adapter sleeve to move along the outer wall of the thread teeth.

[0011] Preferably, the diameter of one end of the inner wall of the card slot is the same as the diameter of the card block, and the diameter of the other end of the inner wall of the card slot is the same as the diameter of the slot. The card block is inserted into the inner wall of the card slot, and the slot will be close to the top of the inner wall of the card slot when the card block is inserted into the inner wall of the card slot.

[0012] The working principle and beneficial effects of the utility model are:

[0013] 1. First, by putting the second flange on the outer wall of the steel pipe and then aligning it with the first flange, the user only needs to rotate the fixing sleeve to achieve the tight fit of the second flange and the first flange. This process avoids the need to use tools or bolts in traditional installations, thereby greatly simplifying the installation process. For the installation of large equipment or long-distance pipelines, this design can significantly shorten the installation time, reduce labor costs, and improve overall installation efficiency. In addition, since the step of inserting bolts is omitted, the problems that may be caused by loose or missing bolts are also reduced. This design not only simplifies the installation process, but also improves the accuracy and reliability of the installation. Such a convenient installation can save some energy for the staff, thereby improving the installation efficiency of the staff, and the installation quality will also be improved accordingly.

[0014] 2. Another major advantage of this high-density flange design is that it significantly improves the firmness of the connection. Traditional flange connections sometimes have loose connections due to factors such as materials, processes or use environment, which may cause leakage or equipment failure. This problem is effectively solved through the innovative matching structure of the card block and the card slot. In the process of the second flange and the first flange being close together, the card block will gradually insert into the inner wall of the card slot. This matching design of the card block and the card slot utilizes the effects of the pressure spring and the telescopic rod, so that the card column can penetrate into the inner wall of the card slot to form a stable connection. This design structure not only provides a strong clamping force to ensure a close fit between the flanges, but also can effectively resist external shocks and vibrations. In addition, the design of the sealing ring also enhances the sealing of the connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In this embodiment, a clamping block 12 is installed on the top of the sealing block 10 , a slot 13 is installed on the top of the clamping block 12 , a telescopic rod 14 is installed on the inner wall of the slot 13 , and the telescopic rod 14 can be driven by the clamping column 16 to be telescopic.

[0026] In this embodiment, a pressure spring 15 is installed around the outer wall of the telescopic rod 14, and a clamping column 16 is installed at one end of the telescopic rod 14. When the telescopic rod 14 contracts, the pressure spring 15 will also contract, and when the pressure spring 15 rebounds, it will drive the telescopic rod 14 to extend.

[0027] In this embodiment, the fixing groove 7 is installed on the inner wall of the fixing sleeve 5, and the diameter of the inner wall of the fixing groove 7 is adapted to the diameter of the fixing block 2. Due to the fixing groove 7, the user can directly rotate the fixing sleeve 5. At this time, the fixing sleeve 5 can rotate along the outer wall of the first flange 1 without affecting the first flange 1.

[0028] In this embodiment, a cavity is provided on the inner wall of the fixing sleeve 5 , and the diameter of the cavity of the fixing sleeve 5 matches the diameter of the first flange 1 , and the fixing sleeve 5 is sleeved on the outer wall of the first flange 1 .

[0029] In this embodiment, one end of the adapting sleeve 11 is provided with a thread, and the thread of the adapting sleeve 11 is adapted to the thread teeth 6 , and the thread teeth 6 will drive the adapting sleeve 11 when rotating.

[0030] In this embodiment, the diameter of one end of the inner wall of the card slot 4 is the same as the diameter of the card block 12, and the diameter of the other end of the inner wall of the card slot 4 is the same as the diameter of the slot 13. A cavity is provided at one end of the slot 13, and the diameter of the cavity of the slot 13 is the same as the diameter of the card column 16.

[0031] The working principle of this utility is:

[0032] First, when using the utility model, you need to put the second flange 8 on the outer wall of the steel pipe, and then align the second flange 8 with the first flange 1. After the second flange 8 is aligned with the first flange 1, you need to rotate the fixing sleeve 5. When the fixing sleeve 5 is rotated, the threaded teeth 6 arranged on the inner wall of the fixing sleeve 5 will rotate along the thread of the adapting sleeve 11. At this time, the second flange 8 will slowly fit tightly with the first flange 1, and while the second flange 8 and the first flange 1 are fit tightly, the clamping block 12 will gradually be inserted into the inner wall of the clamping groove 4. In the process of inserting the clamping block 12 into the inner wall of the clamping groove 4, the clamping column 16 will be squeezed by the inner wall of the clamping groove 4. At this time, the clamping column 16 will drive the pressure spring 15 to contract, and the synchronous telescopic rod 14 will also contract. At this time The clamping column 16 will be synchronously and slowly inserted along the inner wall of the clamping slot 4 until the slot 13 is completely in contact with the inner wall of the telescopic rod 14. Since the clamping column 16 is not restricted by the inner wall of the clamping slot 4, the pressure spring 15 will rebound at this time. When the pressure spring 15 rebounds, it will drive the telescopic rod 14 to extend. At this time, the telescopic rod 14 will drive the clamping column 16 to extend. At this time, the clamping column 16 can be stuck on the inner wall of the clamping slot 4. This design can strengthen the installation of the first flange 1 and the second flange 8. After the installation is completed, the first flange 1 and the second flange 8 will be tightly attached. At the same time, the sealing ring 9 will form a sealing effect inside. In addition, the previously mentioned rotating fixing sleeve 5 for installation eliminates the step of inserting bolts for installation by the installer, making the installation more convenient.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
