Abstract
Description
Technical Field
[0001] This utility model generally relates to the technical field of rivets, and more specifically to a waterproof rivet and a container. Background Technology
[0002] Waterproof rivets are widely used in containers, box trucks, and refrigerated trucks. However, when using waterproof rivets in areas with large interlayer gaps, these gaps are difficult to eliminate, leading to rivet loosening and poor waterproofing. Utility Model Content
[0003] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.
[0004] To at least partially solve the above problems, the first aspect of this utility model provides a waterproof rivet, the waterproof rivet comprising:
[0005] A rivet body having an inlet end and an outlet end, the rivet body being provided with a riveting hole and a stepped hole, the inner diameter of the stepped hole being larger than the inner diameter of the riveting hole, the riveting hole communicating with the stepped hole, and the stepped hole being located at the outlet end of the rivet body, the riveting hole communicating with the inlet end of the rivet body.
[0006] A rivet core, wherein the rivet core has a groove, and the diameter of the portion of the rivet core located on both sides of the groove along the axial direction of the rivet core is not less than and less than the inner diameter of the riveting hole, respectively. The groove is recessed into the rivet core along the radial direction of the rivet core. The rivet core is used to pass through the riveting hole and the stepped hole to the rivet body; and
[0007] A locking ring is fitted onto the nail core and positioned within the riveting hole.
[0008] According to the first aspect of the present invention, the waterproof rivet moves from the riveting end to the riveting exit end of the rivet body during the riveting process. At the same time, the locking ring deforms with the movement of the rivet core and is locked between the groove and the stepped hole of the rivet core. This prevents the rivet core from detaching from the rivet body and keeps it pressed against the rivet body. It also keeps the riveting end of the rivet body expanded, so that the workpiece to be processed is continuously subjected to force, making it less prone to loosening and providing good waterproof effect.
[0009] Optionally, the waterproof rivet further includes a mounting washer, which is used to be disposed at the riveting end of the rivet body and abut against the nozzle of the rivet gun;
[0010] In this process, under the traction of the rivet gun, the rivet core moves from the rivet inlet end to the rivet outlet end between the rivet inlet position and the rivet outlet position, so that the part of the rivet core with a diameter greater than the inner diameter of the rivet hole enters the rivet hole. The groove of the rivet core at the rivet outlet position forms a deformation fit space with the assembly washer and the stepped hole structure, respectively. The locking ring abuts against the assembly washer as the rivet core moves, and thus deforms and fills the deformation fit space under the squeezing action of the rivet core and the assembly washer, so that the rivet core is fixed relative to the rivet body.
[0011] Optionally, the dimension of the locking ring along the axial direction of the waterproof rivet is larger than the dimension of the stepped hole along the axial direction.
[0012] Optionally, the nail core includes a head end, a groove portion, and a rivet portion, the groove being disposed in the groove portion, the diameter of the head end being larger than the inner diameter of the rivet hole, and the diameter of the rivet portion being smaller than the diameter of the rivet hole.
[0013] Optionally, the groove extends around the groove portion along the circumferential direction of the nail core.
[0014] Optionally, along the axial direction of the nail core, the diameter of the groove portion gradually decreases and then increases to form the groove on the outer side of the groove portion.
[0015] Optionally, the inner surface of the groove is arc-shaped.
[0016] Optionally, a cut-off groove is provided between the groove portion and the riveting portion along the axial direction of the nail core; and / or
[0017] The riveting part is provided with assembly ribs and threaded grooves.
[0018] Optionally, the rivet body is further provided with a tapered transition hole, which connects to the riveting hole and the stepped hole along the axial direction of the rivet body.
[0019] Optionally, the riveting end of the rivet body is configured to form a fixed cover. Under the traction of the rivet gun, the head end enters the rivet body, thereby causing the riveting inlet end of the rivet body to expand in the radial direction of the rivet body.
[0020] Optionally, the outer side of the rivet body is provided with threads, and at least a portion of the threads are arranged at the riveting end of the rivet body along the axial direction of the rivet body.
[0021] The second aspect of this utility model provides a container, wherein the container employs at least one waterproof rivet as described above.
[0022] According to the second aspect of this utility model, the container is riveted with waterproof rivets, which makes it less prone to loosening and provides good waterproofing. Attached Figure Description

[0045] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.
[0046] Figures 1 to 4 A waterproof rivet according to the present invention is shown. The waterproof rivet includes a rivet body 100, a rivet core 110, a locking ring 120, and an assembly washer 130.
[0047] The rivet body 100 has an infeed end 101 and an outfeed end 102. The rivet body 100 is provided with a riveting hole 103 and a stepped hole 104. The inner diameter of the stepped hole 104 is larger than the inner diameter of the riveting hole 103, and the riveting hole 103 communicates with the stepped hole 104. The stepped hole 104 is located at the outfeed end 102 of the rivet body 100, and the riveting hole 103 communicates with the infeed end 101 of the rivet body 100.
[0048] The rivet core 110 is provided with a groove 111. The diameter of the portion of the rivet core 110 located on both sides of the groove 111 along the axial direction Z of the rivet core 110 is not less than and less than the inner diameter of the riveting hole 103, respectively. The groove 111 is recessed into the rivet core 110 along the radial direction D of the rivet core 110. The rivet core 110 is used to pass through the riveting hole 103 and the stepped hole 104 to the rivet body 100. The locking ring 120 is sleeved on the rivet core 110 and arranged in the riveting hole 103. The mounting washer 130 is arranged at the riveting end 102 of the rivet body 100 and abuts against the nozzle of the rivet gun.
[0049] Under the traction of the rivet gun, the rivet core 110 moves from the rivet entry end 101 toward the rivet exit end 102 between the rivet entry position and the rivet exit position, so that the portion of the rivet core 110 with a diameter larger than the inner diameter of the riveting hole 103 enters the riveting hole 103. The groove 111 of the rivet core 110 at the rivet exit position forms a deformation fit space 119 with the assembly washer 130 and the stepped hole 104, respectively. The locking ring 120 abuts against the assembly washer 130 as the rivet core 110 moves, thereby deforming and filling the deformation fit space 119 under the compression of the rivet core 110 and the assembly washer 130, so that the rivet core 110 is fixed relative to the rivet body 100.
[0050] According to the waterproof rivet of this utility model, during the riveting process, the rivet core 110 moves from the riveting inlet end 101 to the riveting outlet end 102 of the rivet body 100 until the rivet core 110 is in the riveting outlet position, forming a deformation fit space 119. At the same time, the locking ring 120 deforms and fills the deformation fit space 119 as the rivet core 110 moves, so that the locking ring 120 is engaged between the groove 111 and the stepped hole 104 of the rivet core 110. This prevents the rivet core 110 from detaching from the rivet body 100 and keeps it pressed against the rivet body 100. It also keeps the riveting inlet end 101 of the rivet body 100 expanded, so that the workpiece to be processed is continuously subjected to force, making it less prone to loosening and providing good waterproof effect.
[0051] Reference Figure 2 Along the axial direction Z, the riveting hole 103 in the riveting body 100 communicates with the stepped hole 104. The riveting body 100 is also provided with a tapered transition hole 105, which connects the riveting hole 103 and the stepped hole 104 along the axial direction Z of the riveting body 100. This allows the rivet core 110 to exert not only a resisting force along the axial direction Z on the riveting body 100, but also an expansion force along the radial direction D on the riveting end 102 of the riveting body 100, making the riveting body 100 more stable. In addition, the tapered transition hole 105 makes the transition between the stepped hole 104 and the riveting hole 103 smooth, and also facilitates the construction of a deformation fit space 119 for the deformation of the locking ring 120.
[0052] Optionally, refer to Figure 1 The dimension h1 of the locking ring 120 along the axial direction Z of the waterproof rivet is greater than the dimension h2 of the stepped hole 104 along the axial direction Z, combined with Figure 4 As shown, this allows the deformed locking ring 120 to be interference-fitted into the stepped hole 104, improving the sealing performance of the waterproof rivet.
[0053] Furthermore, the dimension h1 of the locking ring 120 along the axial direction Z of the waterproof rivet is greater than the sum of the dimension h2 of the stepped hole 104 along the axial direction Z and the dimension h3 of the tapered transition hole 105 along the axial direction Z, thereby allowing the deformed locking ring 120 to be interference-fitted into the stepped hole 104 and the tapered transition hole 105, further improving the sealing performance of the waterproof rivet.
[0054] Reference Figure 2 The riveting end 102 of the rivet body 100 forms a fixing cover 106, and the stepped hole 104 communicates with the outer wall of the fixing cover 106. Under the traction of the rivet gun, the rivet core 110 enters the rivet body 100, thereby causing the riveting end 101 of the rivet body 100 to expand in the radial direction D of the rivet body 100, thus enabling the rivet body 100 to achieve the following on both sides of the workpiece: Figure 4 The fastening connection between the first component to be processed 140 and the second component to be processed 150 is shown.
[0055] Optionally, the outer side of the rivet body 100 is provided with threads 107, and at least a portion of the threads 107 are arranged at the riveting end 101 of the rivet body 100 along the axial direction Z. This allows the riveting end 101 of the rivet body 100 to bite into the workpiece to be processed (especially the first workpiece to be processed 140) when it expands, thereby further strengthening the connection between the rivet body 100 and the workpiece to be processed, making the first workpiece to be processed 140 and the second workpiece to be processed 150 more secure.
[0056] Specifically, regarding the structure of nail core 110.
[0057] Reference Figure 3 The rivet core 110 includes a head end 112, a groove portion 113, and a riveting portion 114, with the groove 111 located in the groove portion 113. The diameter of the head end 112 is larger than the inner diameter of the riveting hole 103, and the diameter of the riveting portion 114 is smaller than the diameter of the riveting hole 103. Figure 4As shown, during the riveting process, the rivet core 110 is first passed through the riveting part 114 through the riveting hole 103 and the stepped hole 104 in sequence. Then, the rivet gun is used to connect the riveting part 114 to perform the riveting operation, so that the head end 112 enters the riveting hole 103 of the rivet body 100 through the riveting end 101 of the rivet body 100. This causes the riveting end 101 of the rivet body 100 to expand outward in the radial direction D, so that the riveting end 101 of the rivet body 100 has a contacting force on the first workpiece 140 toward the second workpiece 150. With the fixing cover 106 of the rivet body 100, the first workpiece 140 and the second workpiece 150 are connected and fastened. During the riveting process, since the diameter of the head end 112 is larger than the diameter of the riveting part 114, the locking ring 120 remains in the groove part 113 until the rivet core 110 is in the riveting position. A deformation fit space 119 is formed between the groove 111 of the groove part 113, the stepped hole 104, and the inner wall of the assembly washer 130. The locking ring 120 is also deformed under the compression and fills the deformation fit space 119, so that the rivet core 110 and the rivet body 100 are locked together. This makes the sealing between the rivet core 110 and the rivet body 100 better and further improves the waterproof performance of the waterproof rivet.
[0058] Optionally, along the circumferential direction of the nail core 110, the groove 111 extends around the groove portion 113, so that the structure of the locking ring 120 is consistent at all points around the nail core 110 after deformation, making the force on the nail core 110 more uniform and further improving the sealing performance between the nail core 110 and the rivet body 100.
[0059] Optionally, along the axial direction Z of the nail core 110, the diameter of the groove portion 113 gradually decreases and then increases to form a groove 111 on the outer side of the groove portion 113. Therefore, along the axial direction Z, the locking ring 120 can be well supported at both ends of the groove portion 113, so that the locking ring 120 can be firmly fixed on the outer side of the groove portion 113 during the riveting process.
[0060] As an alternative, the groove 111 can also be configured such that the diameter of the groove portion 113 gradually increases along the axial direction Z of the rivet core 110, and the locking ring 120 can be engaged between the rivet core 110 and the rivet body 100 after riveting.
[0061] Furthermore, the inner surface of the groove 111 is arc-shaped, which makes the locking ring 120 fit smoothly with the inner surface of the groove 111 when it deforms, making the locking ring 120 easy to deform and fill the deformation fit space 119.
[0062] Optionally, refer to Figure 1 and Figure 4Along the axial direction Z of the rivet core 110, a cutting groove 115 is provided between the groove portion 113 and the riveting portion 114 to facilitate cutting off the rivet core 110 after riveting, so that the rivet core 110 will not protrude from the rivet body 100, thereby making the waterproof rivet flatter after riveting.
[0063] Optionally, the riveting part 114 is provided with a mounting rib 116, which engages with the inner hole of the mounting washer 130, making the rivet core 110 and the mounting washer 130 more secure during riveting. The riveting part 114 is also provided with a threaded groove 117, which can be engaged with a rivet gun, thereby facilitating the riveting and cutting operations of the rivet core 110.
[0064] After riveting is completed, the assembly washer 130 can be automatically detached or manually removed, such as... Figure 4 As shown, this completes the riveting of the first component 140 and the second component 150 to be processed.
[0065] Optionally, the rivet core 110 further includes a transition portion 118, the diameter of which is equal to or smaller than the inner diameter of the riveting hole 103. The transition portion 118 is disposed along the axial direction Z between the head end portion 112 and the groove portion 113, allowing for a smooth transition between the head end portion 112 and the groove portion 113. Furthermore, by adjusting the dimension of the transition portion 118 along the axial direction Z, the distance between the head end portion 112 and the groove portion 113 can be adjusted according to different processing requirements (e.g., the thickness of the part to be processed), resulting in a tighter connection between the parts to be processed.
[0066] This utility model also provides a container, wherein the container employs at least one waterproof rivet as described above. The container according to this utility model, using waterproof rivets for riveting, is less prone to loosening and provides excellent waterproofing.
[0067] For example, waterproof rivets can be used to rivet between the top plate and the top crossbeam of a container. The first part to be processed 140 is the top plate, and the second part to be processed 150 is the top crossbeam. The rivet between the top plate and the top crossbeam is achieved by using waterproof rivets.
[0068] It is understood that riveting between the floor and bottom crossbeams of the container, riveting between the side panels and frame of the container, and other riveting processes involving the container should all be within the scope of protection of this utility model.
