FIG. 2 is another schematic structural view of the present invention;
fig. 3 is a schematic structural diagram of the usage state of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
As shown in fig. 1 and 3, a bolt helmet includes a cap body 100 formed by injection molding of a rubber material, a sealing partition plate 101 is disposed in the middle of an inner cavity of the cap body 100, a closed bolt cavity 102 is formed above the sealing partition plate 101, an open nut cavity 103 is formed below the sealing partition plate 101, a metal structural adhesive 104 is filled in the bolt cavity 102, the sealing partition plate 101 is made of a material such as plastic and rubber, and can be damaged after being extruded by a bolt, so that a bolt rod enters the bolt cavity 102. A stepped surface is formed at the joint of the nut cavity 103 and the bolt cavity 102 in the cap body 100, and the edge of the sealing partition plate 101 is fixedly bonded with the stepped surface, so that the sealing partition plate 101 is fixed in the cap body 100.
In addition, after the cap body 100 is installed in place, a space is reserved between the top of the bolt cavity 102 and the bolt rod, so that the situation that after the bolt rod enters the bolt cavity 102, the metal structure glue 104 is greatly compressed to block the bolt from entering the bolt cavity can be avoided, and the extrusion force of the metal structure glue 104 can be reduced through the reserved space, so that the metal structure glue 104 can slowly and uniformly flow to the thread, and the bonding is more uniform. The broken seal spacer 101 may remain in the space, and the screw connection and adhesion are not affected.
When using this helmet to carry out safety protection to the bolt, withhold the nut and press the helmet downwards with the opening of helmet, make nut chamber 103 and nut closely cooperate, outstanding bolt shank portion contacts with seal spacer 101 simultaneously, and tear seal spacer 101, get into the air in the bolt chamber 102, metal structure glue 104 in the bolt chamber 102 slowly passes through seal spacer 101 tear hole department, along the even nut screw department that permeates of the screw thread of bolt, metal structure glue 104 and bolt, the nut contact takes place the reaction, metal structure glue 104 solidification after the certain time, closely adhere bolt and nut together, and then reach the purpose that prevents that the nut from becoming flexible and droing on the bolt.
At the edge of the open end of the cap body 100 there is a horizontally outwardly extending sealing bead 105. The arrangement of the sealing flanging 105 can enable the lower end face of the protective cap to be tightly attached to the upper end face of a steel plate, the bolt and the nut cover matched with the bolt are isolated from the outside, rainwater is prevented from entering the protective cap to leak into the steel plate, and therefore the bolt and the nut are prevented from being exposed to rain and sunlight, the bolt and the nut cannot be corroded to rust, and the bolt and the nut are well protected.
In addition, in order to increase the adhesion between the sealing flange 105 and the steel plate, the lower end surface of the sealing flange 105 is also provided with a circle of groove or a plurality of small grooves, so that a suction cup structure can be formed, and the adsorption performance of the sealing flange 105 is enhanced.
As shown in fig. 2, a first reinforcing steel plate 106 is embedded in the sidewall of the cap body 100 corresponding to the nut cavity 103, and a second reinforcing steel plate 107 is embedded in the sealing flange 105, both of which play a role in reinforcing the strength of the helmet.
The cross section of the nut cavity 103 is circular or regular polygon, and/or the cross section of the bolt cavity 102 is circular or regular polygon, and the size of the cap body 100 can be adjusted according to the size of a specific bolt and nut.
The above is only the preferred embodiment of the present invention, and any person can make some simple modifications, deformations and equivalent replacements according to the present invention, all fall into the protection scope of the present invention.
