Abstract
The utility model provides an antidisassembling screw bolt and a refrigerated container which connects the cooling machine and the container body of the refrigerated container by adopting the antidisassembling screw bolt. The antidisassembling screw bolt comprises a screw bolt head with the edge angle, a screw rod body which is provided with the screw in the part of length range at least, a screw bolt head without the edge angle, and a stress concentration slot. The surface of the screw bolt head without the edge angle is the smooth arc structure. The stress concentration slot is provided between the screw bolt head without the edge angle and the screw bolt head with the edge angle. After the screw bolt is provided, the outside of the screw bolt of the cooling machine is only provided with the screw bolt head without the edge angle. The exterior of the container body can not be clamped by a wrench, and then the antidisassembling screw bolt can not be disassembled. Thus, the utility model has the advantages of good antiassembling effect, difficult illegal damage, and simple installation technique route.
Description
Technical field
The utility model relates to a kind of tamper bolt, relates in particular to the tamper bolt that a kind of casing of Refrigerated container is connected with cold machine.
Background technique
Refrigerated container generally is made up of casing and cold machine, and casing and cold machine link together with hex head bolt.Its casing part is made up of the side plate with heat insulating function, top board, floor and forward and backward frame etc.Preceding frame 1 is welded by preceding back timber 11, preceding bottom girder 13, headpin 12 etc., and the opening that surrounds has therebetween formed and cold machine 2 corresponding interface.Be welded with nut in preceding back timber 11 around the cold machine interface, preceding bottom girder 13, the headpin 12, cold machine 2 be bound up with preceding frame 1 from the common connecting bolt 3 of casing external application.In order to prevent that cold machine 2 from being dismantled by malice, being positioned at has four hex head bolts 4 on the diagonal, and its head is drilled with aperture, will be positioned at two hex head bolts 4 of homonymy respectively with finer wire 5 and be serially connected, at last with lead sealing 6 sealings.If dismantle cold machine 2, must earlier lead sealing 6 or steel wire 5 be destroyed, thereby stay cold machine 2 by the sharp trace of illegal dismounting, do not stolen or changed behind customs seal with the goods in the guard box.
The envelope mode of executing that steel wire adds lead sealing mainly is by the principle that finer wire 5 restriction hex head bolts 4 rotate cold machine to be executed envelope, and the intensity of finer wire 5 is lower, uses common cutting pliers it can be cut off, and is easy to destroy.The seal of lead sealing 6 ratio is easier to forge in addition, and cold machine 2 is very big with the interface area of casing, in case cold machine 2 is illegally pulled down, burglar or terrorist just may be from goods in the cold machine interface theft case, even in case, put into the high-risk material, and jeopardize the public's safety, thus the potential safety hazard of causing.In addition, owing to after connecting bolt installs, also to wear steel wire in addition, the lead extrusion envelope, process route is more loaded down with trivial details.
The model utility content
Technical problem to be solved in the utility model provides a kind of tamper bolt that is difficult for unauthorised broken.
In order to solve the problems of the technologies described above, tamper bolt of the present utility model, it comprises band corner angle bolt head, screwed screw rod body in the partial-length scope at least, and it also comprises: no corner angle bolt head, its surface is smooth arcuate structure; Stress is concentrated groove, and it is located between described no corner angle bolt head and the band corner angle bolt head.
Reasonablely be, described no corner angle bolt head and described have also comprise connecting rod between the corner angle bolt head, described stress concentrates groove to be arranged on the side of described connecting rod near no corner angle bolt head.
The utility model also provides a kind of Refrigerated container that adopts above-mentioned tamper bolt to connect cold machine of Refrigerated container and casing.
Reasonablely be to have at least one to be the tamper bolt in the cold machine of Refrigerated container and the bolt that casing is connected.
Reasonablely be, have at least two to be the tamper bolt in the cold machine of Refrigerated container and the bolt that casing is connected, it lays respectively on two relative or adjacent limits of cold machine.
The installation process of described tamper bolt is as follows, moment on being applied to the corner angle bolt head is during greater than rating value, concentrate groove place generation stress to concentrate at the stress that the corner angle bolt head is arranged and do not have between the corner angle bolt head, the allowable stress limit that surpasses bolt material, there is the corner angle bolt head near the stress of no corner angle bolt head is concentrated groove, under the fracture, only to stay no corner angle bolt head part.
No corner angle bolt head is only left in cold machine bolt outside after installing, can't clamp with wrench outside casing, thereby can't get off the tamper Bolt dismantling, improved the tamper effect, has reached the tamper bolt and has been not easy the purpose of illegally being taken apart.Carry out lead sealing owing to need not wear steel wire in addition after the tamper bolt is tightened, thereby simplified process route, improved efficiency.
Reasonablely be, have corner angle bolt head specification identical,, can enhance productivity so that can all connecting bolts be tightened with same instrument with the specification of the bolt head of other connecting bolt.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
Fig. 3 has provided at cold machine 2 of Refrigerated container and casing and has adopted the bolted embodiment of the utility model tamper, and two tamper bolts 44 of the present utility model lay respectively on the cold machine two opposite edges, and other bolt is common connecting bolt 3.
As shown in Figure 4: tamper bolt 44 of the present utility model, it comprises:
Band corner angle bolt head 441, its surface are provided with the corner angle that extend vertically, and it is the hex head bolt head in this specific embodiment;
No corner angle bolt head 444, its surface are smooth arcuate structure, and it is the hemisphere bolt head in this specific embodiment;
Connecting rod 442, it is used for connecting band corner angle bolt head 441 and does not have corner angle bolt head 444;
Stress is concentrated groove 443, it is located between described no corner angle bolt head 444 and the connecting rod 442, in this specific embodiment, it is V-arrangement that this stress is concentrated the cross section of groove, and its intersecting line by the transverse section of the head curved surface of no corner angle bolt head 444 and connecting rod 442 forms naturally.
