Description

Technical Field

[0001] The utility model belongs to the technical field of bolts, and in particular relates to a riveted cone bolt. Background Art

[0002] A bolt assembly is a commonly used connecting and fixing member used to connect and assemble various components, and a traditional bolt assembly usually includes a bolt column and a bolt cap; for example Figure 1 In the process of connecting and assembling two thin-walled panels 1, the bolt column 2 is inserted into the holes 101 on the two thin-walled panels 1 at the same time, and then the bolt cap 3 is screwed into the end of the bolt column 2, so that the two thin-walled panels 1 are connected and assembled.

[0003] However, conventional bolt connections usually require enlarging the hole 101 on the thin-walled plate 1 so that the diameter of the hole 101 is 2 mm to 4 mm larger than the diameter of the bolt column 2 to ensure the passability of the bolt column 2. However, since the diameter of the hole 101 is larger than the diameter of the bolt column 2, external water will penetrate through the gap between the hole 101 and the bolt column 2 after assembly, and the connection does not have a waterproof effect. Utility Model Content

[0004] Based on the problems mentioned in the above background technology, the utility model provides a riveted conical bolt for solving the problem of traditional bolt connection. Since the diameter of the hole 101 is larger than the diameter of the bolt column 2, external water will penetrate from the gap between the hole 101 and the bolt column 2 after assembly, and the problem of not having a waterproof effect is caused.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A riveted cone bolt, comprising:

[0007] A thin-walled plate, wherein two thin-walled plates are provided, and tapered holes are provided on the side walls of the butt ends of the two thin-walled plates;

[0008] The connecting column comprises a tapered portion and a threaded portion. The threaded portion of the connecting column is inserted along the large end of the tapered hole so that the tapered portion of the connecting column is tightly attached to the inner walls of the two tapered holes. A bolt nut is screwed into the threaded portion.

[0009] On the basis of the above technical solution, the present invention also makes the following improvements:

[0010] Furthermore, the thread of the threaded portion is half-thread and has a tapered shape.

[0011] Further, the diameter of the tapered portion is um-um larger than the diameter of the tapered hole.

[0012] Furthermore, the tapered portion is connected to the threaded portion via a horn tapered portion.

[0013] Furthermore, a washer is sleeved on the horn conical portion of the connecting column, and a horn hole that fits with the horn conical portion is provided in the middle of the washer.

[0014] Beneficial effects of the utility model:

[0015] By making the thread of the bolt part into a half-thread and a tapered shape, and providing a tapered part on the connecting column, during installation, the bolt cap exerts a pulling force on the connecting column to pull the connecting column into a tapered hole slightly smaller than the tapered part of the connecting column, so that the tapered part of the connecting column fits tightly with the tapered hole wall, thereby avoiding the formation of a gap between the connecting column and the tapered hole, thereby achieving a waterproof effect.

[0022] like Figure 1 to Figure 3 As shown, a riveted cone bolt comprises:

[0023] A thin-walled plate 1, wherein two thin-walled plates 1 are provided, and tapered holes 110 are provided on the side walls of the butt ends of the two thin-walled plates 1;

[0024] The connecting column 12 includes a tapered portion 1201 and a threaded portion 1202. The diameter of the tapered portion 1201 is 5um-10um larger than the diameter of the tapered hole 110, so that after the threaded portion 1202 of the connecting column 12 is inserted along the large end of the tapered hole 110, the tapered portion 1201 of the connecting column 12 can be closely attached to the inner walls of the two tapered holes 110;

[0025] The threaded portion 1202 is screwed with a bolt cap 3, and the thread of the threaded portion 1202 is half-threaded and has a tapered shape, so that after the bolt cap 3 is screwed onto the threaded portion 1202, the thread of the bolt cap 3 and the thread groove of the threaded portion 1202 are more tightly fitted;

[0026] The conical portion 1201 is connected to the threaded portion 1202 through the horn conical portion 1203, which can enhance the strength of the joint between the conical portion 1201 and the threaded portion 1202, reduce the stress there, and avoid fracture there;

[0027] A washer 13 is sleeved on the horn cone portion 1203 of the connecting column 12, and a horn hole 1301 is provided in the middle of the washer 13 to fit the horn cone portion 1203. The provided washer 13 can increase the contact surface between the bolt cap 3 and the thin-walled plate 1; and the setting of the horn hole 1301 and the horn cone portion 1203 can enhance the contact area between the washer 13 and the connecting column 12.

[0028] When in use, the threaded portion 1202 of the connecting column 12 is inserted along the large end of the tapered hole 110, so that the connecting column 12 is simultaneously inserted into the tapered holes 110 on the two thin-walled plates 1, and then the washer 13 is sleeved on the horn tapered portion 1203, and finally the bolt cap 3 is screwed onto the threaded portion 1202, so that the tapered portion 1201 of the connecting column 12 is pulled into the tapered hole 110 which is slightly smaller than the tapered portion 1201 by the screwing action of the bolt cap 3 and the threaded portion 1202, so that the tapered portion 1201 of the connecting column 12 is tightly fitted with the wall of the tapered hole 110 on the thin-walled plate 1, thereby avoiding the formation of a gap between the tapered portion 1201 of the connecting column 12 and the tapered hole 110 of the thin-walled plate 1, so as to achieve a waterproof effect.

[0029] The utility model is described in detail above. The description of the specific embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
