Features thus defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "multiple" means two or more unless otherwise explicitly specified.
[0053] According to a first aspect of this application, an insert 100 is provided, with reference to... Figure 1 The insert 100 in this embodiment includes a locking part 140 and a locking segment 130.
[0054] In this embodiment, the locking part 140 is used to lock the relative position of the insert 100 and the insert 200, and the locking segment 130 is connected to the locking part 140.
[0055] The insert 100 in this embodiment is further provided with a deformation groove 100a, which extends along the axial direction of the insert 100 to at least the locking portion 140 and the locking section 130.
[0056] In the embodiments of this application, through the above technical solution, during the connection process between the insert 100 and the insert to be inserted 200, when the locking section 130 and the locking part 140 are subjected to radial force and locked, the deformation groove 100a can cause the locking section 130 of the insert 100 to deform, thereby avoiding the situation where the locking section 130 is deformed due to excessive force on the insert 100, and ensuring the stability of the connection between the insert 100 and the insert to be inserted 200.
[0057] refer to Figure 1 and Figure 2 In this embodiment of the application, the deformation groove 100a extends along the axial direction of the insert 100 to the locking part 140 and the locking section 130 in a connected manner. The deformation groove 100a is constructed as a through groove that penetrates the radial direction of the insert 100, and the deformation groove is a closed groove along the axial direction.
[0058] In some embodiments of this application, the insert 100 further includes a plug segment 110.
[0059] refer to Figure 1In this embodiment of the application, the plug segment 110 is used to form a connection with the locking segment 130. In this embodiment of the application, the locking segment 130 is located between the locking part 140 and the plug segment 110, and at least a portion of the deformation groove 100a extends along the axial direction of the insert 100 toward the plug segment 110.
[0060] Thus, with at least a portion of the deformation groove 100a extending axially along the insert 100 to the locking part 140, the locking section 130, and the insertion section 110, a deformation groove 100a of a certain length can be constructed in the axial direction of the insert 100, further constructing a distributed deformation space that bears radial pressure. This deformation groove 100a can provide a space required for deformation when the insert 100 is locked, that is, when the locking part 140, the locking section 130, and the insertion section 110 are subjected to radial force, the locking part 140, the locking section 130, and the insertion section 110 can undergo a certain degree of radial deformation, avoiding excessive stress concentration in the locking part 140, the locking section 130, and the insertion section 110 under the action of radial force, which would cause the insert 100 to deform and fail to connect stably with the insert 200.
[0061] In some embodiments, the insert 100 further includes a transition section 120. (See reference...) Figure 1 The transition section 120 is located between the insertion section 110 and the locking section 130, and the outer diameter of the insertion section 110 is less than or equal to the outer diameter of the transition section 120.
[0062] When the outer diameter of the insertion section 110 is smaller than the outer diameter of the transition section 120, the ease of insertion of the insertion piece 100 and the piece to be inserted 200 can be improved, and it can play a guiding role when inserting the insertion piece 100 and the piece to be inserted 200, thereby improving the smoothness of insertion.
[0063] Of course, the outer diameter of the plug section 110 can also be set to be equal to the outer diameter of the transition section 120.
[0064] In some embodiments, reference Figure 3 , Figure 4 and Figure 5 The locking segment 130 has a first preset slope along the axial direction.
[0065] The first preset slope is greater than 0 and less than 1, that is, the outer peripheral wall of the locking segment 130 is inclined from left to right, and the outer diameter of the outer peripheral wall of the locking segment 130 gradually increases. In this way, during the insertion process between the insert 100 and the insert to be inserted 200, the locking segment 130 can play a guiding role in the radial and axial directions, and can switch between static friction locking and dynamic friction releasing, so that the locking segment 130 can be stably connected after contacting the inner peripheral wall of the insert to be inserted 200, preventing loosening.
[0066] For example, the tilt angle of the locking segment 130 can be set to 10°. The tilt angle of the outer peripheral wall of the locking segment 130 is relatively small. Of course, it can also be 12° or 45°. The specific tilt angle is set according to the actual use. That is, the first preset slope of the locking segment can be tan(10°)≈0.1763, tan(12°)≈0.2126, or tan(45°)≈1. In the embodiments of this application, the tilt slope of the locking segment 130 is not limited.
[0067] In some embodiments, the locking part 140 is configured as a curved surface, which can not only play a certain guiding role, but also further reduce stress concentration and improve the pressure distribution between the locking part 140 and the inner peripheral wall surface of the insert 200 after the insert 100 and the insert 200 are inserted.
[0068] refer to Figure 5 For example, the locking part 140 can be constructed as an arc surface with an arc of 40°, or of course, it can be 30° or 60°, which is not limited here.
[0069] In some embodiments, the insert 100 further includes a connecting segment 150.
[0070] refer to Figure 5 In this embodiment, the connecting segment 150 is connected to the end of the locking part 140 away from the locking segment 130. This arrangement can improve the reliability of the connection between the insert 100 and the insert to be inserted 200 during the insertion process.
[0071] In some embodiments, the outer diameter of the connecting segment 150 can be set to be equal to the outer diameter of the transition segment 120. Of course, the outer diameter of the connecting segment 150 can also be set to be greater than the outer diameter of the transition segment 120. The embodiments of this application do not limit this, and the actual use shall prevail.
[0072] It should be noted that the reference Figure 9 and Figure 10 In this embodiment, at least a portion of the deformation groove 100a also extends to the connecting section 150, and together with the deformation groove 100a extending to at least a portion of the locking part 140, the locking section 130 and the insertion section 110, they form a closed groove structure, further optimizing the stress distribution to reduce the fatigue of the insert 100.
[0073] In some embodiments, the insert 100 further includes a base segment 160.
[0074] refer to Figure 1In this embodiment, the base segment 160 is connected to the end of the connecting segment 150 away from the locking part 140, and the outer diameter of the base segment 160 is larger than the outer diameter of the connecting segment 150. As a segment that can provide basic support, the base segment 160 is set to have a larger outer diameter than the connecting segment 150. When connecting other external components, such as the insert 100, it can provide structural support and enhance the overall strength.
[0075] The deformation groove 100a in this embodiment can also extend axially to the transition section 120, pass through the locking section 130 and the locking part 140, and extend axially to the preset position of the connecting section 150, without extending to the insertion section 110.
[0076] Thus, the insert 100 provides a space that allows the transition section 120, locking section 130, locking part 140, and connecting section 150 to deform. That is, after the transition section 120, locking section 130, locking part 140, and connecting section 150 are subjected to radial force, the transition section 120, locking section 130, locking part 140, and connecting section 150 can generate a certain deformation displacement towards the center of the insert 100 and can recover radially, making the connection between the insert 100 and the insert 200 more stable.
[0077] Of course, at least a portion of the deformation groove 100a can also be formed in the insertion section 110 and located inside the end of the insertion section 110, which is also a closed deformation groove 100a that does not penetrate the end of the insertion section 110.
[0078] In some embodiments, the outer diameter of the plug segment 110 is set to be smaller than the outer diameter of the locking segment 130. For example, the outer diameter of the plug segment 110 can be set to be smaller than the outer diameter of the narrowest part of the locking segment 130.
[0079] In some embodiments, the outer diameter of the plug segment 110 is different from the outer diameter of the connecting segment 150. For example, the outer diameter of the plug segment 110 can be set to be smaller than the outer diameter of the connecting segment 150.
[0080] In this application, the deformation groove 100a is a straight groove structure formed on the insert 100.
[0081] One, two, or three or more deformation grooves 100a may be formed around the central axis of the insert 100. The specific number is not limited in the embodiments of this application.
[0082] It should be noted that when the number of deformation grooves 100a is four, the four deformation grooves 100a are evenly distributed around the central axis of the insert 100 on the wall of the insert 100, and penetrate the wall of the insert 100 radially.
[0083] In this embodiment, the insert 100 can be constructed as a cylindrical tube.
[0084] According to a second aspect of this application, a support device 10 is provided, the support device 10 including an insert 100 as described above and an insert 200 interlocked with the insert 100.
[0085] The support device 10 in this embodiment includes the insert 100 as described above, and therefore has all the beneficial effects described in the insert 100 above, which will not be repeated here.
[0086] In this embodiment, the component to be inserted 200 is also constructed as a cylindrical tube, and the two cylindrical tubes are inserted together to achieve assembly.
[0087] In some embodiments, the insert 200 is formed with a socket segment 220 connected to the insert 100, wherein at least a portion of the socket segment 220 in this embodiment surrounds the locking segment 130 of the insert 100, thereby enabling the assembly of the insert 100 and the insert 200.
[0088] refer to Figure 6 , Figure 7 and Figure 8 When the insert 200 is inserted into the insert 100, the sleeve section 220 is sleeved on the outside of the insert section 110, transition section 120, locking section 130, locking part 140 and connecting section 150 of the insert 100.
[0089] In some embodiments, reference Figure 8 The socket section 220 is formed by: a locking part 210.
[0090] In this embodiment, the locking part 210 is used to interlock with the locking part 140 to lock the insert 200 and the insert 100.
[0091] It should be noted that the interlocking of the locking part 210 and the locking part 140 means that the locking part 210 and the locking part 140 apply a force to each other, such as friction, as a blocking force, so that the connector and the connector to be inserted are interlocked and the two will not produce relative displacement.
[0092] In this embodiment, the locking part 210 includes a guide surface 211 and a contact surface 212.
[0093] refer to Figure 8The axial projection area of the guide surface 211 is larger than the axial projection area of the contact surface 212. This provides a good guiding effect for the locking section 130 of the insert 100. The contact surface 212 contacts the locking part 140 and serves as a load-bearing surface. Its smaller area is beneficial for the stable connection between the insert 100 and the insert to be inserted 200.
[0094] In some other embodiments, the guide surface 211 and the contact surface 212 of the locking part 210 can also be configured to be symmetrically arranged, that is, the axial projection area of the guide surface 211 is equal to the axial projection area of the contact surface 212.
[0095] In some embodiments, the guide surface 211 in this application embodiment is configured as a surface that slopes upward from left to right, while the contact surface 212 is configured as a surface that slopes downward from left to right. The guide surface 211 and the contact surface 212 are smoothly transitioned, and the slope of the guide surface 211 is less than that of the contact surface 212. This makes the locking part 210 form a structure with one side steep and the other side gentle. In this case, it is easy to install and difficult to disassemble the insert 100 and the insert 200.
[0096] In this embodiment, the guide surface 211 and the contact surface 212 are constructed as arc-shaped surfaces.
[0097] Of course, the guide surface 211 and the contact surface 212 in this embodiment can also be constructed as inclined planes, and the slopes of the guide surface 211 and the contact surface 212 in this embodiment are set differently. For example, the absolute value of the slope of the guide surface 211 can be less than the absolute value of the slope of the contact surface 212. At the same time, the slope of the guide surface 211 in this embodiment is greater than 0, and the slope of the contact surface 212 is less than 0. That is, the extension directions of the guide surface 211 and the contact surface 212 are different, that is, they are intersecting.
[0098] For example, in the embodiments of this application, when the guide surface 211 and the contact surface 212 are constructed as inclined planes, the inclination angle of the guide surface 211 is set to 30° and the inclination angle of the guide surface is set to 135°, so the slope of the guide surface 211 is... The slope of the contact surface 212 is -1.
[0099] Of course, in some other embodiments, the guide surface 211 may be constructed as an inclined plane, the contact surface 212 may be constructed as an arc surface, and the two may be smoothly transitioned together.
[0100] It should be noted that the locking part 140 in the embodiments of this application can be constructed as a continuous arc surface. Of course, it can also be constructed as a discontinuous arc surface. For example, the locking part 140 can be constructed as multiple protrusions.
[0101] In this embodiment, the outer diameter of the insertion segment 110 is also smaller than the outer diameter of the connecting segment 150. In this case, interference between the insertion segment 110 and the locking part 210 can be avoided when the insert 100 and the insert to be inserted 200 are inserted.
[0102] In the embodiments of this application, the insertion direction of the insert and the insert to be inserted 200 can be, for example, from left to right, which makes insertion convenient, requires no tool assistance, and facilitates modular processing. During the insertion process, the position of the deformation groove 100a of the insert will undergo slight deformation.
[0103] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
