Description

Technical Field

[0001] The utility model relates to the technical field of embedded nuts, and more specifically to an anti-loosening and dust-proof embedded nut. Background Art

[0002] Anti-loosening and dust-proof embedded nut is a special nut design, which has two main functions: anti-loosening and dust-proof. Anti-loosening function: This nut increases the friction or resistance with the thread through special structural design or adding special materials, thereby preventing the bolt from loosening. For example, it may adopt a locking structure, such as a locking gasket, locking rope, locking ring, etc., or use highly elastic materials, such as spring steel or elastic plastic. When the nut is tightened, the material will produce elastic deformation and apply additional tightening force to the thread. In addition, compression design is also a common anti-loosening measure, which increases the friction with the thread mating surface by generating a mismatch during the tightening process, thereby preventing loosening.

[0003] Among them, the patent with patent application number CN202220071416.2 discloses the technical field of embedded nuts, specifically, it relates to a hexagonal embedded nut, including an embedded nut body, a first threaded hole is opened at the center of the upper surface of the embedded nut body, an annular groove is opened on the upper surface of the embedded nut body, an upper prism is arranged above the embedded nut body, a threaded column is arranged at the lower surface of the upper prism corresponding to the annular groove, a second threaded hole is opened at the center of the upper prism, a limit column is arranged on the upper surface of the upper prism, and a conical column is arranged on the lower surface of the embedded nut body;

[0004] When this structure is in use, the overall structural stability is increased by the embedded nut body and the conical column, which is convenient for combination and fixation with an external screw rod and the coordinated use of the embedded parts. The upper prism is convenient for combination and connection with the embedded nut body in cooperation with the threaded column and the annular groove, thereby further increasing the embedded strength. However, this structure is not easy to position the nut as a whole when in use, resulting in a poor anti-loosening effect. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides an anti-loosening and dust-proof embedded nut, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-loosening and dust-proof embedded nut, comprising a reinforced protective tube, on which a positioning protection component is provided;

[0007] The positioning protection assembly comprises a limit top plate arranged on the top of the reinforced protection tube, a nut body is arranged in the middle of the limit top plate, and the nut body extends to the middle of the reinforced protection tube;

[0008] Side top seats are fixedly provided on both sides of the surface of the reinforced protective tube, and a limiting stop block is provided inside each of the side top seats, one side of the two limiting stop blocks is provided with a contact arc slope, the contact arc slope penetrates the reinforced protective tube and extends to the outside of the nut body, the middle part of the limiting stop block is rotatably connected with a support shaft, the support shaft is inserted into the side top seat and is detachably connected to the side top seat, a limiting pin is provided on the side of the limiting stop block away from the contact arc slope, and the limiting pin is inserted into the side top seat.

[0009] It can be seen that in the above technical solution, the nut body is protected by the reinforced protective tube and the limiting top plate to realize the function of wrapping protection, thereby preventing external dust from entering between the nut body and the workpiece to be fixed. At the same time, in order to ensure the stability of the nut body when it is locked, the limiting pin is plugged into the side top seat. When the limiting pin contacts the limiting stop block, the limiting stop block is rotated along the axis point of the connection between the limiting stop block and the support shaft by the traction force when the limiting pin is inserted, so that the contact arc slope can be pressed against the outside of the nut body to position the nut body. At the same time, the limiting pin is limited by the side top seat to avoid the return phenomenon after the limiting stop block and the contact arc slope contact the nut body, thereby preventing the nut body from loosening.

[0010] Optionally, in a possible implementation manner, a limiting cylinder groove is provided through the limiting top plate, the limiting cylinder groove matches the nut body, the limiting cylinder groove is clamped with the nut body, a positioning ring is sleeved on the outer side of the nut body, an inner lining is provided inside the positioning ring, the inner lining is clamped with the nut body, and the outer side of the positioning ring extends to the inner wall of the reinforced protective cylinder;

[0011] It can be seen that in the above technical solution, the top end of the nut body is limited by the limiting top plate and the limiting cylinder groove, while the middle part of the nut body is limited by the positioning ring and the lining, so that when the bolt rotates on the nut body, the nut body can always be fixed in the reinforced protective cylinder in the same axial direction as the bolt, avoiding looseness and causing deformation of the workpiece when the bolt and the nut body are calibrated.

[0012] Technical effects and advantages of the utility model:

[0013] By setting the positioning protection component, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding coordination of various structures, the nut body is protected by the reinforced protection tube and the limit top plate, realizing the function of wrapping protection, preventing external dust from entering between the nut body and the workpiece to be fixed;

[0014] The limit pin is inserted into the side top seat. When the limit pin contacts the limit stop block, the limit stop block is rotated along the axis point of the connection between the limit stop block and the support shaft by the traction force when the limit pin is inserted, so that the contact arc slope can be pressed against the outside of the nut body to position the nut body. At the same time, the limit pin is limited by the side top seat to avoid the limit stop block and the contact arc slope from returning to the nut body after contacting the nut body, thereby preventing the nut body from loosening.

[0023] As attached Figure 1-4 The anti-loosening and dust-proof embedded nut shown in the figure has a positioning protection component arranged on the strengthening protection tube 1, and the nut body 3 is protected by the strengthening protection tube 1 and the limiting top plate 2, so as to realize the function of wrapping protection, and prevent external dust from entering between the nut body 3 and the workpiece to be fixed. At the same time, in order to ensure the stability of the nut body 3 when being locked, the limiting pin 8 is inserted into the side top seat 4. When the limiting pin 8 contacts the limiting stop block 5, the limiting stop block 5 is subjected to the traction force when the limiting pin 8 is inserted and rotates along the axis point of the connection between the limiting stop block 5 and the support shaft 7, so that the contact arc slope 6 can be pressed against the outside of the nut body 3 to position the nut body 3. At the same time, the limiting pin 8 is limited by the side top seat 4, so as to prevent the limiting stop block 5 and the contact arc slope 6 from returning to their original position after contacting the nut body 3, and prevent the nut body 3 from loosening. The specific structure of the component is arranged as follows;

[0024] The positioning protection component includes a limiting top plate 2 arranged on the top of the reinforced protection tube 1, a nut body 3 is arranged in the middle of the limiting top plate 2, and the nut body 3 extends to the middle of the reinforced protection tube 1;

[0025] Side top seats 4 are fixedly provided on both sides of the surface of the reinforced protective tube 1, and a limiting stop block 5 is provided inside each side top seat 4. A contact arc slope 6 is provided on one side of the two limiting stop blocks 5. The contact arc slope 6 penetrates the reinforced protective tube 1 and extends to the outside of the nut body 3. A support shaft 7 is rotatably connected to the middle part of the limiting stop block 5. The support shaft 7 is inserted into the side top seat 4 and is detachably connected to the side top seat 4. A limiting pin 8 is provided on the side of the limiting stop block 5 away from the contact arc slope 6, and the limiting pin 8 is inserted into the side top seat 4.

[0026] A limiting cylindrical groove 9 is formed through the limiting top plate 2, which matches the nut body 3. The limiting cylindrical groove 9 is clamped with the nut body 3. A positioning ring 10 is sleeved on the outer side of the nut body 3. An inner lining 11 is provided inside the positioning ring 10. The inner lining 11 is clamped with the nut body 3. The outer side of the positioning ring 10 extends to the inner wall of the reinforced protective tube 1.

[0027] When in use, the staff installs the device at the designated position according to the above structure, and the nut body 3 is protected by the reinforced protective tube 1 and the limiting top plate 2 to realize the function of wrapping protection, and prevent external dust from entering between the nut body 3 and the workpiece to be fixed. At the same time, in order to ensure the stability of the nut body 3 when being locked, the limiting pin 8 is inserted into the side top seat 4. When the limiting pin 8 contacts the limiting stop block 5, the limiting stop block 5 is subjected to the traction force when the limiting pin 8 is inserted and rotates along the axis point of the connection between the limiting stop block 5 and the support shaft 7, so that the contact arc slope 6 can be pressed against the outside of the nut body 3 to position the nut body 3. At the same time, the limiting pin 8 is limited by the side top seat 4, so as to prevent the limiting stop block 5 and the contact arc slope 6 from returning to their original position after contacting the nut body 3, and prevent the nut body 3 from loosening.

[0028] At the same time, when the device is in use, the top end of the nut body 3 is limited by the limiting top plate 2 and the limiting tube groove 9, while the positioning ring 10 and the lining 11 limit the middle part of the nut body 3, so that when the bolt rotates on the nut body 3, the nut body 3 can always be fixed in the reinforced protective tube 1 in the same axial direction as the bolt, avoiding looseness and causing deformation of the workpiece when the bolt and the nut body 3 are calibrated.

[0029] Different from the prior art, the present application discloses an anti-loosening and dust-proof embedded nut, which protects the nut body 3 by a reinforced protective tube 1 and a limiting top plate 2, thereby realizing the function of wrapping protection, preventing external dust from entering between the nut body 3 and the workpiece to be fixed. At the same time, in order to ensure the stability of the nut body 3 when it is locked, the limiting pin 8 is inserted into the side top seat 4. When the limiting pin 8 contacts the limiting stop block 5, the limiting stop block 5 is rotated along the axial point of the connection between the limiting stop block 5 and the support shaft 7 by the traction force when the limiting pin 8 is inserted, so that the contact arc slope 6 can be pressed against the outside of the nut body 3 to position the nut body 3. At the same time, the limiting pin 8 is limited by the side top seat 4, so as to avoid the limiting stop block 5 and the contact arc slope 6 from returning to the original position after the contact with the nut body 3, thereby preventing the nut body 3 from loosening.
