Description
The present invention relates to a kind of seal-locking mechanism, it is used for sealing locking railcar and shipping container, and other object such as warehouse, storehouse, shop, booth, groove jar etc., and can be used for sealing locking can be in the railcar and shipping container, truck and other means of transportation freight, and be used to seal and lock for example door of refrigerator, victualler, van and other automobile.
Immediate prior art is seen Soviet Union's certificate of invention No. 1288747, international classification number G 09F 3/03,1984, its described device comprises that one has the body of head, a fixed block and a locking element, wherein, fixed block is made the form of a housing and a retainer, and locking element is made the form of spring.
It is complicated that the major defect of said apparatus has the complicated screw thread in nut that it is made.In addition, locking device needs special tool, brings inconvenience to use; But also will be with a hand simultaneously set screw nut and housing in the lug (lug) of object to be locked, and the another hand is being placed on special tool on the head of body outside the lug of object to be locked.Can't use in the possible displacement process of this known device lug in the railcar, and can not be used for sealing can be at railcar and shipping container freight.In order to use in the object of lug with different size and lug spacing, this device needs individually to make, and this brings difficulty and defective in operation.
The present invention is in order to overcome the problems referred to above of the prior art, the purpose of this invention is to provide a kind of seal-locking mechanism, it is compared with the well known device of same use, can simplify manufacture process, easy to use and reliable, can reuse after only more replacing a part.
The above-mentioned advantage of seal-locking mechanism can be according to the invention provides, wherein, locking element is made the form of cylindrical bar, it has the end that comes to a point in a side, at opposite side one head is arranged, the part of the side surface of cylindrical bar is shaped on the monocline serration, fixed block is made the form of at least two separation members, it has the outer conical surface corresponding to the internal conical surface of making in the body, an and internal surface, make the monocline serration thereon and contact with the relevant serration of locking element, described fixed block is with respect to the body spring-loaded, and the information that needs is applied on the end face of locking element head, next-door neighbour's locking element head, be provided with annular groove on the smooth cylndrical surface of locking element, a cylindrical sleeve is installed in described annular groove top, can rotate.
In addition, seal-locking mechanism of the present invention can be provided with a lid, it is shaped on an external cylindrical surface and a head, they are corresponding to the external cylindrical surface and the head of body, described lid can be arranged on the body on the supporting surface on lid and the body, form the single external cylindrical surface of seal-locking mechanism, the head of lid comprises an inner chamber, and described locking element head is set in this inner chamber.
Contrast the following drawings is more specifically described the present invention by way of example now.
Fig. 1 represents an embodiment of seal-locking mechanism;
Fig. 2 represents same embodiment, but has an additional cap.
Consult accompanying drawing now, represent the present invention among the figure, it comprises a body 1 that has head 2; A locking element 3 of making the rod type of the cylinder shape belt head 4 that has come to a point end 5 and monocline serration 6; A fixed block 7 of making at least two separation member forms, separation member has outer conical surface 8, and the internal conical surface of it and body 1 is corresponding, wherein, forms on the internal surface of each fixed block 7 corresponding to the monocline serration of the monocline serration 6 of locking element 3.Described fixed block 7 by means of a spring 9 and with respect to the fixing packing ring 10 of body 1 and spring-loaded.On the end face of the head 4 of locking element 3, apply needed information.Next-door neighbour's head 4, be provided with an annular groove 11 on the smooth cylinder of locking element 3, at upside of the ring groove one cylindrical sleeve 12 be set, an end of sleeve is rolled into annular groove 11 slightly, described cylindrical sleeve 12 freely is arranged on the side of locking element 3, can rotate thereon.According to the present invention, seal-locking mechanism can be provided with a lid 13, and it is shaped on an external cylindrical surface and a head 14.It is corresponding to the external cylindrical surface and the head 2 of body 1.On the bearing surface 15 on lid 13 and the body 1, lid 13 is arranged on the body 1, thereby forms an external cylindrical surface of body 1 and lid 13.Body 1 and cover the pitch that screw thread on locking element 3 and the fixed block 7 can be depended in maximal clearance between 13 the interface.In lid 13 head 14, be provided with an inner chamber 16, its corresponding to the head 4 of locking element 3 so that when locking, described head is located in inner chamber.
Seal-locking mechanism uses in the following manner.
In advance fixed block 7 is installed in the body 1, and by spring 9 and packing ring 10 spring-loaded, packing ring 10 is fixing rigidly with respect to body 1, thus form a kind of inseparable, reusable structure.The body 1 that will have a fixed block 7 with a hand passes lug immediately, and with the another hand one locking element 3 is inserted bodies, makes its longitudinal axis misalignment fixed block 7 of end along seal-locking mechanism that come to a point.When separating when mobile, described fixed block 7 can make locking element 3 pass body 1, until the moment that the similar serration of the monocline serration of fixed block 7 and locking element 3 contacts.
Also be in advance cylindrical sleeve 12 freely to be arranged on the cylndrical surface of locking element 3, can to rotate thereon, sleeve ends can be rolled in the annular groove 11 made of head 4 of next-door neighbour's locking element 3 slightly.The existence of above-mentioned cylindrical sleeve 12 provides in the situation that unauthorized is opened, for example, a kind of supplementary protection when the sawed-off locking element 3 of attempt, this is because in said circumstances, cylindrical sleeve 12 will rotate, thereby can prevent above-mentioned sawed-off.The next-door neighbour is provided with, promptly, the annular groove 11 that is provided with in the bottom of the head 4 of locking element 3 is determined the place of the intentional setting that head 4 fractures in can the unauthorized opening procedure at seal-locking mechanism, and limits breaking force by the size of structurally determining described annular groove 11.
If necessary, seal-locking mechanism also comprises a lid 13, and it is to set in advance on body 1 on the supporting surface 15 with fixed block 7 identical modes.Covering 13 seal-locking mechanism setting can be that cost guarantees the good reliability of locking by increasing structural strength, and go for locking the various objects that have lug, in every kind of specific situation, lug has the fixed dimension of being determined by total cylndrical surface of body 1 and lid 13.
When closure, all members of seal-locking mechanism form a kind of rigid construction.In order to open it, need apply sizable power, this requires to use special device, and its closed available manual implementation need not special experience and instrument.When opening, only damage the part of the intentional weakening of locking element 3, then the remaining part of described locking element 3 is freely released body.The remaining part of seal-locking mechanism is reusable, thereby can reduce manufacturing cost and use cost.
