Description

Technical Field

[0001] The utility model relates to the field of rivets, in particular to a high-strength hollow long rivet. Background Art

[0002] Hollow rivets are usually used in clothing, footwear and other industries. Solid rivets need to be riveted again. They are used to connect heavy workpieces and are often non-detachable structures. Semi-hollow rivets are the most widely used. The tie-mouth (smaller wire diameter at the end) rivets are made of hard wire and can penetrate steel plates within 0.5mm thickness without pre-holes. Rivets cannot bend and deform. They are widely used in password boxes, suitcases and military bags. Hollow nails (semi-hollow rivets) are made of soft wires. Generally, they are required not to crack after riveting. There are many types. Nowadays, semi-hollow nails or mother-and-child nails have been widely used to replace the shafts on some toys, which can greatly reduce production costs. Pull-out and core-driving rivets are mostly used for riveting thinner and softer materials. Generally, the requirements are not strict, and the materials used for manufacturing are usually made of materials with better plasticity.

[0003] Most of the hollow rivets nowadays are made by bend- ing the end of the rivet tube by hammering. When the end of the rivet tube and the rivet cap are in close fit with the object, the riveting is completed. Although this method is easy to install, it can only be disassembled by cutting, which is time-consuming and labor-intensive and not safe enough. Moreover, most of the rivets nowadays are of fixed length, making it difficult to rivet objects of different thicknesses, and the scope of application is relatively small. Utility Model Content

[0004] Technical problems solved: Disassembly by cutting is troublesome and cannot be applied to objects of different thicknesses.

[0005] In view of the deficiencies in the prior art, the utility model provides a high-strength hollow long rivet, which solves the problems mentioned in the background technology.

[0006] Technical solution:

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A high-strength hollow long rivet comprises a nail cap, a nail tube is fixedly connected to the bottom of the nail cap, a mounting plate is movably connected to the inside of the nail tube, a plurality of through holes are penetrated through the inner walls on both sides of the nail tube, two groups of fixing rods matched with the size of the through holes are arranged on the top of the mounting plate, a driving assembly is arranged on the top of the mounting plate, and an adjusting assembly is arranged on the bottom of the mounting plate.

[0009] In one possible implementation, the drive assembly includes a gear, a mounting block, gear teeth, a guide groove and a guide block, the gear being movably connected to a rotationally connected to the top center of a mounting plate, the mounting block being fixedly connected to the bottom inner end of a fixing rod and being located on both sides of the gear, the gear teeth being fixedly connected to one side of the mounting block and meshing with the gear, the guide groove being opened at the top of the mounting plate and being located at the bottom of the mounting block, and the guide block being fixedly connected to the bottom of the mounting block and being slidably connected to the guide groove.

[0010] In a possible implementation, the drive assembly also includes a vertical rod, a through slot and a connecting rod, the vertical rod passes through and is movably connected to the mounting plate, the through slot passes through the middle of the vertical rod, and the connecting rod is fixedly connected to the inside of the gear and slidably connected to the through slot.

[0011] In a possible implementation, the driving assembly further includes a rotating groove, a rotating block and a groove, wherein the rotating groove is opened at the top of the nail cap, the rotating block is fixedly connected to the top of the vertical rod and rotatably connected to the rotating groove, and the groove is opened at the top of the rotating block.

[0012] In a possible implementation, the adjustment component includes an adjustment slot, an adjustment rod, a vertical slot, a card slot and a card block, the adjustment slot passes through the inner walls on both sides of the nail tube, the adjustment rod is slidably connected to the adjustment slot, the vertical slots are opened on the inner walls on both sides of the adjustment slot, the card slots are provided in several groups and are opened on one side of the vertical slot, the spacing of the card slots is the same as the spacing of the through holes, and the card block is fixedly connected to both sides of the adjustment rod near the outer end and is adapted to the sizes of the vertical slot and the card slot.

[0013] In a possible implementation, the adjustment assembly also includes a slide groove, a slider and a spring. The slide groove is opened at the bottom of the mounting plate, the slider is fixedly connected to the top of the inner end of the adjustment rod and is slidably connected to the slide groove, and the spring is fixedly installed inside the slide groove and its two ends are respectively fixedly connected to one side of the slider and the inner wall of one side of the slide groove.

[0014] Beneficial effects:

[0015] First, by providing a driving assembly, when an object needs to be riveted, first pass the nail tube through the rivet hole, then place a flat-blade screwdriver in the groove and turn the screwdriver to drive the rotating block to rotate along the rotating groove. During this process, the vertical rod rotates synchronously with the rotating block. Since the connecting rod is slidably connected to the through groove, the gear will rotate synchronously with the vertical rod. Since the gear teeth are meshed with the gear and the guide block is slidably connected to the guide groove, the mounting block will move linearly outward along the guide groove as the gear rotates. When the fixing rod moves outward with the mounting block to pass through the through hole, the screwdriver is removed, and the riveting work is completed at this time. This design can make the installation and removal of rivets simpler and faster, and effectively improve work efficiency.

[0016] Secondly, by providing an adjustment component, the adjustment rod is pressed inward to drive the block to move inward. During this process, the slider slides inward along the slide slot synchronously with the adjustment rod and squeezes the spring. When the block moves out of the slot and enters the vertical slot, the adjustment rod is slid along the adjustment slot to adjust the position of the mounting plate through the slider. During this process, the mounting plate will drive the gear and the fixed rod to move synchronously. After adjusting to the appropriate height, the adjustment rod is released, the spring rebounds and drives the adjustment rod to move outward through the slider. When the block moves outward with the adjustment rod to enter the slot at the current position, the position of the mounting plate can be adjusted. This design allows the rivet to rivet objects of different thicknesses by adjusting the position of the mounting plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The embodiments of the present application solve the problems in the prior art by providing a high-strength hollow long rivet.

[0027] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0028] The specific structure of this embodiment is as follows: Figures 1 to 6 As shown, a high-strength hollow long rivet includes a nail cap 1, a nail tube 2 is fixedly connected to the bottom of the nail cap 1, a mounting plate 3 is movably connected inside the nail tube 2, a plurality of through holes 4 are penetrated through the inner walls on both sides of the nail tube 2, two groups of fixing rods 5 matched with the size of the through holes 4 are arranged on the top of the mounting plate 3, a driving assembly 6 is arranged on the top of the mounting plate 3, and an adjusting assembly 7 is arranged at the bottom of the mounting plate 3.

[0029] In some examples, the driving assembly 6 includes a gear 61, a mounting block 62, a gear tooth 63, a guide groove 64 and a guide block 65. The gear 61 is movably connected to the top center of the mounting plate 3, the mounting block 62 is fixedly connected to the bottom of the inner end of the fixing rod 5 and is located on both sides of the gear 61. The gear tooth 63 is fixedly connected to one side of the mounting block 62 and meshes with the gear 61. The guide groove 64 is opened at the top of the mounting plate 3 and is located at the bottom of the mounting block 62. The guide block 65 is fixedly connected to the bottom of the mounting block 62 and is slidably connected to the guide groove 64. Rotating the gear tooth 63 can drive the gear tooth 63 to rotate synchronously. Since the gear tooth 63 is fixedly connected to the mounting block 62 and the guide block 65 is slidably connected to the guide groove 64, the mounting block 62 will move linearly along the guide groove 64 as the gear 61 rotates.

[0030] In some examples, the driving assembly 6 also includes a vertical rod 66, a through slot 67 and a connecting rod 68. The vertical rod 66 passes through and is movably connected to the mounting plate 3. The through slot 67 passes through the middle of the vertical rod 66. The connecting rod 68 is fixedly connected to the inside of the gear 61 and is slidably connected to the through slot 67. Rotating the vertical rod 66 can drive the connecting rod 68 to rotate through the through slot 67, thereby driving the gear 61 to rotate.

[0031] In some examples, the driving assembly 6 also includes a rotating groove 69, a rotating block 610 and a groove 611. The rotating groove 69 is opened at the top of the nail cap 1, the rotating block 610 is fixedly connected to the top of the vertical rod 66 and rotatably connected to the rotating groove 69, and the groove 611 is opened at the top of the rotating block 610. A flat-blade screwdriver is placed in the groove 611, and then the screwdriver is rotated to drive the rotating block 610 to rotate along the rotating groove 69, thereby driving the vertical rod 66 to rotate.

[0032] The cam 74 is provided with a plurality of groups of clamping grooves 74, and the clamping grooves 74 are provided with a plurality of groups of clamping grooves 74. The spacing of the clamping grooves 74 is the same as the spacing of the through holes 4. The clamping block 75 is fixedly connected to the two sides of the adjusting rod 72 near the outer end and is adapted to the sizes of the vertical grooves 73 and the clamping grooves 74. The adjusting rod 72 is pressed inwardly to drive the clamping block 75 from the clamping groove 74 into the vertical groove 73. At this time, the adjusting rod 72 can be slid along the adjusting groove 71 to adjust the position of the mounting plate 3. The adjusting rod 72 can be pulled outward to drive the clamping groove 74 from the vertical groove 73 into the clamping groove 74 to fix the adjusting rod 72 in the current position, thereby completing the adjustment of the position of the mounting plate 3.

[0033] In some examples, the adjustment component 7 also includes a slide groove 76, a slider 77 and a spring 78. The slide groove 76 is opened at the bottom of the mounting plate 3, the slider 77 is fixedly connected to the top of the inner end of the adjustment rod 72 and is slidably connected to the slide groove 76, and the spring 78 is fixedly installed inside the slide groove 76 and its two ends are respectively fixedly connected to one side of the slider 77 and the inner wall of one side of the slide groove 76. The spring 78 can be squeezed by pushing the slider 77 along the slide groove 76 toward the center of the mounting plate 3. When the slider 77 is released, the spring 78 rebounds to drive the slider 77 to move to both sides of the mounting plate 3.

[0034] In a specific application scenario, when it is necessary to rivet an object, first pass the nail tube 2 through the rivet hole, then place a flat-blade screwdriver in the groove 611 and turn the screwdriver to drive the rotating block 610 to rotate along the rotating groove 69. During this process, the vertical rod 66 rotates synchronously with the rotating block 610. Since the connecting rod 68 is slidably connected to the through groove 67, the gear 61 will rotate synchronously with the vertical rod 66. Since the gear teeth 63 are engaged with the gear 61 and the guide block 65 is slidably connected to the guide groove 64, the mounting block 62 will move linearly outward along the guide groove 64 as the gear 61 rotates. When the fixing rod 5 moves outward with the mounting block 62 to pass through the through hole 4, the screwdriver is removed, and the riveting work is completed. Compared with the previous fixing method of knocking to bend the nail tube 2, the fixing method is also stronger and will not crack, etc., and has a longer service life. When the rivet needs to be removed When the block 75 moves outwardly along the adjusting rod 72 to enter the slot 74 at the current position, the adjustment plate 3 can be adjusted by sliding the adjusting rod 72 along the adjusting slot 71.

[0035] By adopting the above technical solution, not only can the installation and removal of the rivet be made simpler and faster, thus effectively improving the work efficiency, but also the rivet can be used to rivet objects of different thicknesses by adjusting the position of the mounting plate.

[0036] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the present invention.
