Abstract
The utility model relates to a reinforcement lock of a round steel ball, which is characterized in that a lock rod hole (2) and an inclined hole (5) are formed on a cylindrical lock body (3); the inclined hole and the lock rod hole are communicated with each other and form an included angle of 14-18 degrees; a steel ball (7) and a spring (6) are arranged in the inclined hole (5) and sealed by a choke plug (4); a clamping groove (1a) is formed at the head part (1b) of a lock rod (1); and when the lock rod is inserted in the lock rod hole, the steel ball is pushed back to the inclined hole and enters into the clamping groove (1a) along the inclined hole under the action of the spring to enable the lock rod to be self-locked. The technical scheme of the lock rod and clamping groove structure matched with the steel ball is adopted so that a tank car to be locked is sealed and locked without looseness; in the locking state, the entire static tension fracture load reaches 2.5 times of standard requirements; and the structure tightens the tank car, and the sealing lock of the tank car is convenient and reliable, without false locking and secondary locking.
Description
Technical field:
The utility model relates to a kind of sealing lock that is exclusively used in the transportation by railroad, particularly a kind of circle steel ball reinforced lock.
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 a kind of circle steel ball reinforced lock that proposes for the defective that solves the prior art existence.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of circle steel ball reinforced lock, it comprises lock body, it is characterized in that: a locking bolt hole and an inclined hole are set in the lock body, inclined hole communicates with the locking bolt hole and is 14-18 degree angle, 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 right cylinder.
Owing to adopt above-mentioned pair of steel ball to cooperate the technical scheme of locking bolt draw-in groove structure, make by the lock tank car and seal the tight lock of realization non-loosening.Whole static fail in tension load reaches 2.5 times of standard-required under locking states.This structure tension tank car sealing lock is convenient and reliable, does not have false locking and secondary locking.
Description of drawings:
Fig. 1 is a cut-open view of the present utility model;
Embodiment:
As shown in Figure 1, circle steel ball reinforced lock described in the utility model, it comprises columniform lock body 3, inside is provided with a locking bolt hole 2 from the side face of cylinder of lock body 3, inside is provided with an inclined hole 5 from the opposite side face of cylinder of lock body 3, inclined hole communicates with the locking bolt hole and is 14-18 degree angle, is provided with steel ball 7 and spring 6 in the inclined hole 5, and they are by plug 4 sealings.Other is provided with a locking bolt 1 that cooperates with locking bolt hole 2, and the head of locking bolt 1 is provided with draw-in groove 1a, 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 1a then.
