Description

Technical Field

[0001] The utility model belongs to the technical field of clothes drying rod accessories, and in particular relates to a bolt head retaining ring structure. Background Art

[0002] In some heavy equipment, some parts are detachably installed with bolts. Due to the working environment, the equipment is often hit by foreign objects during use. Once the exposed bolt head is damaged, it cannot be used, which will affect the maintenance of the equipment in the future. The existing way to protect the bolt head is generally to make a groove at the location where the bolt head is installed, so that the exposed head of the bolt is placed in it after the bolt is tightened, thereby protecting the bolt head. However, some equipment has explosion-proof requirements, and it is also troublesome to process the groove. In addition, the groove will accumulate water, causing the bolt to be corroded. The second problem is to design a structural part that can protect the bolt head. Utility Model Content

[0003] In view of this, the utility model provides a bolt head retainer structure to solve the above-mentioned problems recorded in the background technology.

[0004] In order to achieve the above object, the utility model is implemented through the following technical solutions:

[0005] The utility model provides a bolt head retainer structure, comprising a shell, a accommodating cavity arranged in the shell and a center hole arranged at the bottom of the shell, wherein the bottom of the shell is provided with a plane portion and an inclined portion in sequence from the inside to the outside along the radial direction of the center hole, and a plurality of drainage holes are provided at the connection between the bottom of the shell and the side wall, and the plurality of drainage holes are evenly distributed along the circumferential direction of the bottom of the shell.

[0006] In the above-mentioned bolt head guard ring structure, as a preferred solution, the outer portion of the shell is cylindrical, elliptical or regular hexagonal.

[0007] In the above-mentioned bolt head retainer structure, as a preferred solution, the accommodating cavity is cylindrical or truncated cone-shaped.

[0008] In the above-mentioned bolt head retainer structure, as a preferred solution, the planar portion and the inclined portion form an angle of 5-10°.

[0009] The utility model provides a bolt head retainer structure, which has the following beneficial effects:

[0010] The bolt head guard ring structure provided by the utility model is an independent guard ring structure design, which can avoid grooving on the equipment, greatly reduces the difficulty of processing, and also has the function of protecting the equipment from being damaged; the guard ring structure wraps the bolt head to achieve the purpose of protecting the bolt head from damage; by arranging a drainage hole at the bottom of the accommodating cavity inside the shell, it has the function of preventing water in the accommodating cavity from corroding the bolt; the outer part of the shell is designed to be hexagonal or elliptical, so that when the bolt head is damaged, by welding or fusing the bolt head and the shell together, it has the effect of loosening the bolt as a whole under force.

[0015] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Exemplary embodiments of the present invention are described in detail with reference to the following drawings.

[0017] The meanings of the serial numbers in the figure are: 1 is the shell, 2 is the accommodating cavity, 3 is the drainage hole, 4 is the bolt, 5 is the flat part, 6 is the inclined part, and 7 is the center hole.

[0018] The following describes exemplary embodiments of the present invention in combination with specific circumstances:

[0019] Example 1: Combination Figure 1-Figure 4As shown, the utility model provides a bolt head retainer structure, comprising a housing 1, a receiving cavity 2 arranged in the housing 1, and a center hole 7 arranged at the bottom of the housing 1. The bottom of the housing 1 is provided with a plane portion 5 and an inclined portion 6 in sequence from the inside to the outside along the radial direction of the center hole 7, and a plurality of drainage holes 3 are provided at the connection between the bottom of the housing 1 and the side wall, and the drainage holes 3 are evenly distributed along the circumferential direction of the bottom of the housing. The inclined portion 6 gradually slopes downward from the center hole 7 to the side wall.

[0020] The outer shape of the housing 1 is cylindrical, elliptical or regular hexagonal. The accommodating cavity 2 is cylindrical or truncated cone-shaped; the truncated cone-shaped design has a large opening and a small bottom, which can facilitate the wrench head to enter the bolt during tightening and disassembly. The flat portion 5 at the bottom of the housing 1 forms an angle of 5-10° with the inclined portion 6.

[0021] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
