Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic joints, in particular to a pneumatic joint with anti-loosening threads. Background Art

[0002] The pneumatic joint with anti-loosening thread adopts a specific design and material to prevent loosening during use. This kind of joint not only has the basic functions of pneumatic joints, but also emphasizes the stability and safety of threaded connection.

[0003] When the pneumatic joint is in use, the wear of the pneumatic joint is likely to affect the service life of the pneumatic joint. The smaller the interference fit between the joint clamp and the joint, the lower the pressure resistance of the pneumatic quick-connect joint. It will also reduce the stability of the pneumatic joint and reduce the working efficiency of the pneumatic joint.

[0004] In order to overcome the above-mentioned defects, prior art 1 (application number CN202022128536.5, Chinese patent application date 2022-09-25) is a full-metal pneumatic quick-connect terminal connector with a threaded sealing ring to improve the sealing effect. The end of the hexagonal nut away from the connector body engages the connecting pipe through a thread. The threaded connection can make the connection of the connecting pipe more secure and easy to disassemble and replace, reducing labor while also saving resources. The inner ring of the sealing ring is consistent with the outer ring diameter of the stepped ring, which increases the thickness of the sealing device and is not easy to fall off;

[0005] During use, threaded connections may fail to bear the load and break due to insufficient or uneven prestress, and excessive or insufficient tightening torque during installation may cause damage to the threaded connection, thereby affecting its load-bearing capacity. The above-mentioned device cannot effectively protect the threaded connection head during the operation of the pneumatic joint, nor can it improve the load-bearing capacity of the threaded connection, thereby causing unnecessary trouble.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original all-metal pneumatic quick-connect terminal connector thread with sealing ring. Utility Model Content

[0007] The purpose of the present utility model is to provide a pneumatic joint with anti-loosening threads, so as to solve the problems proposed in the above background technology that threaded connections may fail to bear the load and cause breakage of the bolts due to insufficient or uneven prestress, and that excessive or insufficient tightening torque during installation may cause damage to the threaded connection, thereby affecting its bearing capacity, making it impossible to effectively protect the threaded connection head and unable to improve the bearing capacity of the threaded connection.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a pneumatic joint with anti-loosening thread, comprising a pneumatic pipe joint body, the upper surface of the pneumatic pipe joint body being fixedly connected to a hexagonal nut, the upper surface of the hexagonal nut being fixedly connected to a connecting thread column, and the surface of the connecting thread column being fixedly connected to a connecting column;

[0009] Also includes:

[0010] The inner wall of the connecting column is provided with a moving groove, the interior of the connecting column is slidably connected with a sliding column, and the interior of the connecting column is provided with a connecting groove.

[0011] Preferably, a movable plate is fixedly connected to the inner side of the sliding column, and the sliding columns are symmetrically distributed around the center of the connecting column.

[0012] Preferably, an extrusion sheet is fixedly connected to the left side of the sliding post, and the sliding post passes through the interior of the connecting post.

[0013] Preferably, a moving column is fixedly connected to the inner side of the extrusion sheet, and a telescopic block is elastically connected to the upper surface of the moving column, and the telescopic blocks are symmetrically distributed about the center of the moving column, and the ends of the telescopic blocks are inclined.

[0014] Preferably, a No. 1 spring is fixedly connected to the lower surface of the telescopic block, and the other end of the No. 1 spring is connected to the movable column.

[0015] Preferably, a spring plate is slidably connected to the inner side of the connecting column, a No. 2 spring is fixedly connected to the right side of the spring plate, and the other end of the No. 2 spring is fixedly connected to the connecting column.

[0016] Preferably, a connecting line is connected to the interior of the movable column, and a hand-pull ball is fixedly connected to the left end of the connecting line.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the threaded anti-loosening pneumatic joint adopts a new structural design, the specific contents of which are as follows:

[0018] (1) The pneumatic joint with threaded anti-loosening has a sliding column and a connecting column that fits tightly together. At the same time, the moving groove inside the connecting column restricts and protects the sliding column, effectively reducing the vibration generated during the threaded connection and ensuring the stability of the pneumatic joint.

[0019] Furthermore, the load-bearing capacity of the pneumatic joint is improved, so that the pneumatic joint can more effectively resist the influence of external loads and stresses;

[0020] (2) When the telescopic block enters the connection groove, the pneumatic joint with threaded anti-loosening drives the telescopic block to retract downward, and at the same time, the No. 1 spring retracts toward the inside of the moving column, so that the moving column can normally enter the inside of the connection groove, which can maintain a stable fastening effect for a long time and enhance the durability of the pneumatic joint;

[0021] Furthermore, the telescopic block effectively reduces the looseness of the moving column during connection, thereby improving the protection of the moving column;

[0022] (3) The threaded anti-loosening pneumatic joint has a second spring that accelerates the sliding of the moving column toward the outside of the connecting groove, accelerates the rapid rebound of the moving column, and at the same time makes the pneumatic joint have an elastic buffer function, reduces loss, increases the service life of the pneumatic joint, and improves the working efficiency of the pneumatic joint; BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Embodiment 1: By setting the connection between the connecting column 3 and the movable groove 16, the sliding column 7 slides inside the connecting column 3, as shown in FIG. Figure 1-Figure 3 As shown:

[0033] The pneumatic pipe joint comprises a pneumatic pipe joint body 1, wherein a hexagonal nut 2 is fixedly connected to the upper surface of the pneumatic pipe joint body 1, a connecting thread column 4 is fixedly connected to the upper surface of the hexagonal nut 2, and a connecting column 3 is fixedly connected to the surface of the connecting thread column 4;

[0034] Also includes:

[0035] A moving groove 16 is formed on the inner wall of the connecting column 3 , and a sliding column 7 is slidably connected to the interior of the connecting column 3 . A connecting groove 10 is formed on the interior of the connecting column 3 .

[0036] When the threaded pneumatic joint is working, the sliding post 7 inside the connecting post 3 is moved so that the sliding post 7 fits tightly against the connecting post 3. At the same time, the moving groove 16 inside the connecting post 3 limits and protects the sliding post 7, effectively reducing the vibration generated during the threaded connection, thereby ensuring the stability of the pneumatic joint and improving the load-bearing capacity of the pneumatic joint, so that the pneumatic joint can more effectively resist the influence of external loads and stresses.

[0037] Embodiment 2. In this embodiment, the difference from embodiment 1 is that the connection between the moving column 9, the telescopic block 11 and the first spring 12 is set so that the moving column 9 is engaged with the inside of the connecting column 3, as shown in FIG. Figure 4-Figure 5 As shown:

[0038] The inner side of the sliding column 7 is fixedly connected to the moving plate 5, and the sliding column 7 is symmetrically distributed about the center of the connecting column 3. The left side of the sliding column 7 is fixedly connected to the extrusion piece 6, and the sliding column 7 passes through the interior of the connecting column 3. The inner side of the extrusion piece 6 is fixedly connected to the moving column 9, and the upper surface of the moving column 9 is elastically connected to the telescopic block 11, and the telescopic block 11 is symmetrically distributed about the center of the moving column 9. At the same time, the end of the telescopic block 11 is inclined, and the lower surface of the telescopic block 11 is fixedly connected to the No. 1 spring 12, and the other end of the No. 1 spring 12 is connected to the moving column 9.

[0039] The extrusion sheet 6 is pressed to drive the movable column 9 to slide inside the connecting groove 10. The end of the telescopic block 11 is inclined. When the telescopic block 11 contacts the connecting column 3, the telescopic block 11 is driven to retract downward, and at the same time, the No. 1 spring 12 is driven to retract toward the inside of the movable column 9, so that the movable column 9 can normally enter the inside of the connecting groove 10, which can maintain a stable fastening effect for a long time, extend the service life of the pneumatic joint, and improve the durability of the pneumatic joint.

[0040] Embodiment 3. In this embodiment, different from the embodiment 2, the connection between the connecting column 3, the spring plate 8 and the second spring 15 is provided to enable the moving column 9 to be quickly separated, as shown in FIG. Figure 6-Figure 7 As shown:

[0041] The inner side of the connecting column 3 is slidably connected to a spring plate 8, and the right side of the spring plate 8 is fixedly connected to a No. 2 spring 15, and the other end of the No. 2 spring 15 is fixedly connected to the connecting column 3. The inside of the movable column 9 is connected to a connecting line 13, and the left end of the connecting line 13 is fixedly connected to a hand-pull ball 14.

[0042] When the moving column 9 slides inside the connecting groove 10, the moving column 9 contacts the spring plate 8 inside the connecting groove 10, driving the No. 2 spring 15 to retract toward the inside of the connecting column 3. When the hand-pull ball 14 is pulled, the hand-pull ball 14 drives the connecting line 13, causing the No. 1 spring 12 to retract toward the inside of the moving column 9, driving the telescopic block 11 to retract, thereby causing the moving column 9 to slide toward the outside of the connecting groove 10, so that the pneumatic joint has an elastic buffering function, reduces loss, and increases the service life of the pneumatic joint. At the same time, it accelerates the rapid rebound of the moving column 9 and improves the working efficiency of the pneumatic joint.

[0043] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
