Abstract
The utility model relates to a cube dual-steel ball reinforced lock which is characterized in that a lock plunger hole (4) and a pair of inclined holes (8) are formed in a lock body (5), each inclined hole is communicated with the lock plunger hole with an included angle of 14-18 degrees, a steel ball (6) and a spring (7) are arranged in each inclined hole, the cube dual-steel ball reinforced lock is additionally provided with a lock plunger (2), and a slot (3) is formed at the head part of the lock plunger. When the lock plunger is inserted in the lock plunger hole, the steel balls are extruded back into the inclined holes, and the steel balls enter into the slot under the action of the springs to lead the lock plunger to form the self-locking. The locked seal realizes the tight locking without looseness by adopting the technical proposal of the structure of using two steel balls to be matched with the lock plunger slot. The whole static tensile damage load in the locked state achieves 2.5 times of the standard requirement. With the structure, the sealing is convenient and reliable to carry out, and false locking or secondary locking is avoided.
Description
Technical field:
The utility model relates to a kind of sealing lock that is exclusively used in the transportation by railroad, the two steel ball reinforced locks of particularly a kind of side's body.
Background technology:
Present widely used sealing lock be mainly used in container execute the envelope or box car execute envelope, existing sealing lock mainly cooperates with ground wire rope in the lockhole by ground steel ball, spring in the lock body, with sealing lock self-locking locking, it exist load little, be easy to generate phenomenons such as loosening, false locking.Also there is the structure more complicated in addition, the shortcoming that cost is also higher.
The utility model content:
The purpose of this utility model is exactly the two steel ball reinforced locks of a kind of side's body that propose for the defective that solves the prior art existence.
To achieve these goals, the utility model has adopted following technical scheme:
The two steel ball reinforced locks of a kind of side's body, it comprises a lock body, it is characterized in that: a locking bolt hole and a pair of inclined hole are set in the lock body, each inclined hole communicates with the locking bolt hole and is 14-18 degree angles, be provided with steel ball and spring in the inclined hole, other is provided with a locking bolt that cooperates with the locking bolt hole, and the head of locking bolt is provided with draw-in groove, when locking bolt inserts in the locking bolt hole steel ball is squeezed back in the inclined hole, steel ball enters at the effect lower edge of spring inclined hole and makes locking bolt form self-locking in the draw-in groove then.The lock body profile is a cuboid.Further technical scheme is that locking bolt one end connects wire rope, and the wire rope other end is connected in the cap head.
Owing to adopt above-mentioned pair of steel ball to cooperate the technical scheme of locking bolt draw-in groove structure, make by locked cause for gossip and now tightly lock non-loosening, whole static fail in tension load reaches 2.5 times of standard-required under locking states.It is convenient and reliable that this structure is executed envelope, do not have false locking and secondary locking.
Description of drawings:
Fig. 1 is the cut-open view of the utility model embodiment one;
Fig. 2 is the cut-open view of the utility model embodiment two;
Embodiment:
Embodiment one: as shown in Figure 1, the two steel ball reinforced locks of side's body described in the utility model, it comprises that profile is the lock body 5 of cuboid, one end of lock body 5 is provided with a locking bolt hole 4 to inside, lock body 5 other ends are provided with the inclined hole 8 of a pair of symmetry to inside, each inclined hole communicates with the locking bolt hole and is 14-18 degree angles, is provided with steel ball 6 and spring 7 in the inclined hole 8, and by plug 9 sealings.Other is provided with a locking bolt 2 that cooperates with locking bolt hole 4, locking bolt 2 upper ends are provided with cap head 1, the head of locking bolt 2 is provided with draw-in groove 3, when locking bolt inserts in the locking bolt hole steel ball is squeezed back in the inclined hole, and steel ball enters at the effect lower edge of spring inclined hole and makes locking bolt form self-locking in the draw-in groove 3 then.
Embodiment two: as shown in Figure 2, the basic structure of the two steel ball reinforced locks of side's body described in the utility model is with embodiment one, and difference is that locking bolt 2 one ends connect wire rope 2a, and the wire rope other end is connected in cap head 1.
