Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a bolt head sliding adjustable bolt. Background Art

[0002] Bolt: A mechanical part, a cylindrical threaded fastener equipped with a nut, a type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten two parts with through holes; however, since bolts are prone to rust due to external environmental factors during use, when removing the bolts, it is easy for the head of the bolt to slip from the wrench. At this time, the bolt can only be cut off with a cutting machine, and it is inconvenient to use a wrench to remove it. For this reason, we propose a bolt with a sliding adjustable bolt head. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a bolt with a sliding and adjustable bolt head.

[0004] The technical solution adopted by the utility model to solve the technical problem is a bolt head sliding adjustable bolt, comprising a disc body, the top surface of the disc body is integrally structured with a clamping shaft that can be used for connection, and the outer periphery of the clamping shaft is sleeved with a hexagonal ring;

[0005] The bottom surface of the disk body is integrally constructed with a vertical cylinder for connection, and a threaded rod is slidably installed on the outer periphery of the vertical cylinder. An adjustable screw hole is opened at one end of the threaded rod close to the vertical cylinder, and a screw rod threadably connected to the screw hole is rotatably installed inside the vertical cylinder.

[0006] By adopting the above technical solution, when the object needs to be disassembled after being fastened with a bolt, the wrench and the hexagonal ring on the top of the disc body can be clamped together, and then the bolt can be disassembled. At the same time, when the hexagonal ring and the wrench are threaded, the hexagonal ring can be separated from the clamping shaft on the top of the disc body, so that the hexagonal ring can be replaced easily. At the same time, a special-shaped screwdriver can be directly plugged into the special-shaped hole on the top of the clamping shaft, which is convenient for disassembling the bolt, and the bolt can be disassembled without using a cutting machine.

[0007] When an object is tightened by a bolt but the bolt is not long enough, the screw rod at the bottom of the disk body can be rotated, and the screw rod can be screwed together with the screw hole inside the threaded rod. Since the threaded rod and the vertical cylinder at the bottom of the disk body are slidingly connected to each other and cannot rotate relative to each other, the threaded rod and the vertical cylinder can be separated from each other, and the length of the threaded rod at the bottom of the disk body can be extended, which makes it easy to extend the length of the bolt and tighten the object.

[0008] Specifically, the outer circumferential surface of the clamping shaft and the outer circumferential surface of the vertical cylinder are both provided with arc grooves that can be used for connection, and there are multiple groups of arc grooves. The inner circumferential surface of the hexagonal ring and the inner circumferential surface of the threaded rod are both integrally constructed with arc strips that fit and connect with the arc grooves, and there are multiple groups of arc strips.

[0009] By adopting the above technical solution, the arc strip and the arc groove are fitted and connected with each other, so that after the hexagonal ring and the clamping shaft are clamped with each other, the hexagonal ring and the clamping shaft will not rotate on their own, and at the same time, the stability of the vertical cylinder and the threaded shaft during mutual sliding displacement is improved, which is convenient for further reducing the mutual rotation between the vertical cylinder and the threaded rod.

[0010] Specifically, the outer circumferential surface of the clamping shaft and the outer circumferential surface of the hexagonal ring are both provided with transverse holes that can be used for connection, and studs are threadedly installed inside the transverse holes.

[0011] By adopting the above technical solution, the stud and the transverse hole are threadedly connected to each other, which makes it easy to tighten the position of the hexagonal ring clamped on the outer periphery of the clamping shaft, so that the hexagonal ring can operate more stably and is convenient for disassembly, assembly and replacement.

[0012] Specifically, a swivel seat drivingly connected to the screw rod is assembled on the inner side of the clamping shaft.

[0013] By adopting the above technical solution, the swivel seat installed in the inner groove of the clamping shaft can be easily rotated by a screwdriver, thereby driving the screw rod located in the vertical tube at the bottom side of the disk body to rotate, and adjusting the distance between the threaded rod and the vertical tube.

[0014] Specifically, a rubber cover is clamped on the top surface of the clamp shaft.

[0015] By adopting the above technical solution, the rubber cover and the hole at the top of the clamping shaft are mutually engaged, which facilitates the sealing of the hole at the top of the clamping shaft, thereby reducing the infiltration of dust and debris therein, and also facilitates the disassembly and assembly of the rubber cover.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application adopts the design of the clamping shaft and the hexagonal ring. When an object needs to be disassembled after being fastened with a bolt, the wrench and the hexagonal ring on the top of the disk body can be clamped together, and then the bolt can be disassembled. At the same time, when the hexagonal ring and the wrench are stripped, the hexagonal ring can be separated from the clamping shaft on the top of the disk body, so that the hexagonal ring can be replaced easily. At the same time, a special-shaped screwdriver can be directly plugged into the special-shaped hole on the top of the clamping shaft, which is convenient for disassembly of the bolt, and the bolt can be disassembled without using a cutting machine.

[0018] 2. The technical solution of the present application adopts the design of the vertical tube, threaded rod, screw hole and screw rod. When a bolt is used to tighten an object but the length of the bolt is not enough, the screw rod at the bottom of the disk body can be rotated. The rotation of the screw rod can be screwed into the screw hole on the inner side of the threaded rod. Since the threaded rod and the vertical tube at the bottom of the disk body are slidingly connected to each other and cannot rotate relative to each other, the threaded rod and the vertical tube can be separated from each other, and the length of the threaded rod at the bottom of the disk body can be extended conveniently, so as to extend the length of the bolt and tighten the object conveniently.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figure 1-3 The embodiment of the utility model provides a technical solution: a bolt head sliding adjustable bolt, comprising a disk body 1, the top surface of the disk body 1 is integrally constructed with a clamping shaft 2 that can be used for connection, and the outer periphery of the clamping shaft 2 is sleeved with a hexagonal ring 3; the bottom surface of the disk body 1 is integrally constructed with a vertical cylinder 4 that can be used for connection, and the outer periphery of the vertical cylinder 4 is slidably installed with a threaded rod 5, the end of the threaded rod 5 close to the vertical cylinder 4 is provided with a screw hole 6 that can be used for adjustment, and the inner side of the vertical cylinder 4 is rotatably installed with a screw rod 8 that is threadedly connected to the screw hole 6.

[0026] When in use, when the object needs to be disassembled after being fastened with bolts, the wrench can be used to engage with the hexagonal ring 3 on the top of the disc body 1, and then the bolt can be disassembled. At the same time, when the hexagonal ring 3 and the wrench are threaded, the hexagonal ring 3 can be separated from the clamping shaft 2 on the top of the disc body 1, so that the hexagonal ring 3 can be replaced easily. At the same time, a special-shaped screwdriver can be directly used to engage with the special-shaped hole on the top of the clamping shaft 2, so that the bolt can be disassembled easily, and the bolt can be disassembled without using a cutting machine.

[0027] When an object is fastened with a bolt but the bolt is not long enough, the screw rod 8 at the bottom of the disk body 1 can be rotated, and the screw rod 8 can be screwed together with the screw hole 6 on the inner side of the threaded rod 5. Since the threaded rod 5 and the vertical tube 4 at the bottom of the disk body 1 are slidingly connected to each other and cannot rotate relative to each other, the threaded rod 5 and the vertical tube 4 can be separated from each other, and the length of the threaded rod 5 at the bottom of the disk body 1 can be extended, so that the length of the bolt can be extended, and the object can be fastened.

[0028] like Figure 2 As shown, the outer circumferential surfaces of the clamping shaft 2 and the vertical cylinder 4 are both provided with arc grooves 9 that can be used for connection, and there are multiple groups of arc grooves 9. The inner circumferential surfaces of the hexagonal ring 3 and the inner circumferential surfaces of the threaded rod 5 are both integrally constructed with arc strips 10 that fit and connect with the arc grooves 9, and there are multiple groups of arc strips 10.

[0029] When in use, the arc strip 10 and the arc groove 9 are fitted and connected with each other, so that after the hexagonal ring 3 and the clamping shaft 2 are clamped with each other, the hexagonal ring 3 and the clamping shaft 2 will not rotate on their own, and at the same time, the stability of the vertical tube 4 and the threaded shaft during mutual sliding displacement is improved, which is convenient for further reducing the mutual rotation between the vertical tube 4 and the threaded rod 5.

[0030] like Figure 1 and Figure 2 As shown, the outer circumferential surfaces of the clamping shaft 2 and the hexagonal ring 3 are both provided with transverse holes 11 for connection, and studs 12 are threadedly installed inside the transverse holes 11 .

[0031] When in use, the stud 12 and the transverse hole 11 are threadedly connected to each other, so as to facilitate the tightening of the position of the hexagonal ring 3 clamped on the outer periphery of the clamping shaft 2, so that the hexagonal ring 3 can operate more stably and is convenient for disassembly, assembly and replacement.

[0032] like Figure 3 As shown, a swivel seat 7 drivingly connected to a screw rod 8 is mounted on the inner side of the clamping shaft 2 .

[0033] When in use, the swivel seat 7 installed in the inner groove of the clamping shaft 2 can be easily rotated by a screwdriver, so as to drive the screw rod 8 located in the vertical tube 4 at the bottom side of the disk body 1 to rotate, so as to adjust the distance between the threaded rod 5 and the vertical tube 4.

[0034] like Figure 1 and Figure 2 As shown, a rubber cover 13 is clamped on the top surface of the clamp shaft 2 .

[0035] When in use, the rubber cover 13 and the hole at the top of the card shaft 2 are engaged with each other, which is convenient for blocking the hole at the top of the card shaft 2, thereby reducing the infiltration of dust and debris therein, and also convenient for disassembly and assembly of the rubber cover 13.

[0036] The working principle and use process of the utility model are as follows: when in use, first install the corresponding structural components in a suitable position. When the object needs to be disassembled after being fastened with bolts, the wrench can be used to engage with the hexagonal ring 3 on the top of the disk body 1, and then the bolt can be disassembled. At the same time, when the hexagonal ring 3 and the wrench are slipped, the hexagonal ring 3 can be separated from the clamping shaft 2 on the top of the disk body 1, so that the hexagonal ring 3 can be replaced easily. At the same time, the special-shaped screwdriver can be directly plugged into the special-shaped hole on the top of the clamping shaft 2 to facilitate the bolt. At the same time, when the bolt is used to tighten an object but the bolt is not long enough, the screw rod 8 at the bottom of the disk body 1 can be rotated, and the screw rod 8 can be screwed together with the screw hole 6 on the inner side of the threaded rod 5. Since the threaded rod 5 and the vertical cylinder 4 at the bottom of the disk body 1 are slidably connected to each other and cannot rotate relative to each other, the threaded rod 5 and the vertical cylinder 4 can be separated from each other, and it is convenient to extend the length of the threaded rod 5 at the bottom of the disk body 1, so as to extend the length of the bolt and tighten the object.
