Abstract
The utility model provides a bullet type sealing lock preventing rotation disengaging. The bullet type sealing lock solves the problems that an existing bullet type sealing lock is complex in lock body structure, production efficiency is low, production cost is high, a lock rod can be screwed out in a rotating mode after being locked, the prying prevention function is poor, and requirements of a user can not be completely met. The bullet type sealing lock preventing rotation disengaging comprises a lock body and a lock rod matched with the lock body, and the lock body comprises a transparent outer shell. A lock body inner shell is arranged in the transparent outer shell, and a lock block and a C-shaped spring are arranged in the lock body inner shell. The locking end of the lock body is conical, an annular groove is formed in a position, corresponding to the C-shaped spring, of the locking end of the lock rod, and the transparent outer shell and the lock block are respectively provided with a hole for the lock rod to penetrate through. A protrusion is arranged on a position, corresponding to the transparent outer shell, of the locking end of the lock rod, and the inner side of the hole of the transparent outer shell is provided with a groove matched with the protrusion. The bullet type sealing lock preventing rotation disengaging is used for one-time sealing.
Description
Technical field
The utility model relates to a kind of sealing lock, is specifically related to a kind of anti-rotation bullet type sealing-applying lock that exits.
Background technology
Sealing lock is exactly disposable lock, as long as just can't open after using this so-called sealing lock, only have it is destroyed just passable, so the place of its application is also very extensive, as the industries such as transportation of railway, harbour, aviation, post and telecommunications, electric industry, oil, logistics, fast freight, various model container, oil truck and other items.Execute envelope, locking once completes, and has the special functions such as false proof, antitheft, safety, insurance.Therefore the main performance of sealing lock is embodied in its safety, antitheft aspect.
The bullet type sealing-applying lock used at present comprises locking bar and lock body two large divisions mostly, and lock body is by C type spring, the metal lock dog, and plastic inner shell is plastic to be formed.Described locking bar one end is taper, and is provided with cannelure in tapering point a distance.Described locking bar tapering point is successively through circular hole, C type spring and plastic inner shell on lock dog.When the locking bar tapering point passes through C type spring, C type spring is softened, and locking bar continues forward, and when the cannelure on locking bar arrives C type spring position, C type spring contraction also is stuck in the cannelure on locking bar, thereby by locking bar and lock body locking.But adopt the bullet type sealing-applying lock of this structure, the lock body structure complexity, production efficiency is low, and cost of production is high.And locking bar may be rotated after locking to be back-outed, and tamper-resistant function is slightly poor, can not meet customer need fully.
Summary of the invention
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of anti-rotation bullet type sealing-applying lock that exits, and tamper-resistant function is strong, improving productivity, and cost descends and environmental protection; Anti-tamper performance is splendid.
Above-mentioned purpose is achieved through the following technical solutions:
The anti-rotation bullet type sealing-applying lock that exits, comprise lock body and the locking bar coordinated with lock body, described lock body comprises transparent outer cover, described transparent outer cover the inside arranges the lock body inner casing, described lock body inner casing the inside assembling lock dog and C type spring, the locking end of described locking bar is taper, the position of the corresponding described C type spring of the locking end of described locking bar has cannelure, there is respectively the hole of passing for locking bar on described transparent outer cover and described lock dog, the position of the corresponding described transparent outer cover of the locking end of described locking bar has projection, the inboard, hole of described transparent outer cover has the groove coordinated with described projection.
The described anti-rotation bullet type sealing-applying lock that exits, described lock body inner casing is split-type design, by two arc plastic sheets, is spliced.
The described anti-rotation bullet type sealing-applying lock that exits, described projection has two, lays respectively at the both sides of described locking bar.
Beneficial effect:
1. still rotatable after inserting lock body locking in order to prevent locking bar, the utility model has increased protruding design on locking bar, and after locking, projection is in the groove the inside, and locking bar is not rotatable, has avoided locking bar by revolving the problem that turning is back-outed comes.
2. plastic inner shell of the present utility model is done split type processing and is divided into two arc plastic sheets, has reduced the difficulty of pack into C type spring and lock dog.Reduced human cost.
3. the utility model adopts transparent outer cover, and the mode by ultrasonic bonding is welded on circular lock dog and C type spring on the lock body inner casing, has avoided because plastic and material that produce such as scraps at the problem; And laser marking can see through transparent outer cover and be engraved on the lock body inner casing of plastics, anti-tamper performance is splendid, and outward appearance is more exquisite.

Fig. 2, front view of the present utility model.
The B-B sectional drawing of Fig. 3, Fig. 2.
In figure: 1, locking bar, 2, transparent outer cover, 3, lock dog, 4, C type spring, 5, cannelure, 6, projection, 7, groove, 8, plastic sheet.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
Embodiment 1:
As shown in accompanying drawing 1-3: the anti-rotation bullet type sealing-applying lock that exits of the present utility model, the locking bar 1 that comprises lock body and coordinate with lock body, described lock body comprises transparent outer cover 2, described transparent outer cover the inside arranges the lock body inner casing, described lock body inner casing the inside assembling lock dog 3 and C type spring 4, the locking end of described locking bar is taper, the position of the corresponding described C type spring of the locking end of described locking bar has cannelure 5, there is respectively the hole of passing for locking bar on described transparent outer cover and described lock dog, the position of the corresponding described transparent outer cover of the locking end of described locking bar has projection 6, the inboard, hole of described transparent outer cover has the groove 7 coordinated with described projection.
Embodiment 2:
The anti-rotation difference that exits bullet type sealing-applying lock and embodiment 1 of the present embodiment is, described lock body inner casing is split-type design, by two arc plastic sheets 8, is spliced.
Embodiment 3:
The anti-rotation difference that exits bullet type sealing-applying lock and embodiment 1 or embodiment 2 of the present embodiment is, described projection has two, lays respectively at the both sides of described locking bar.
The locking process:
The tapering point of locking bar is successively through the hole on transparent outer cover, and the hole on lock dog, C type spring, arrive plastic inner shell.When the tapering point of locking bar passes through C type spring, C type spring is softened, and locking bar continues forward, and when the cannelure on locking bar arrives C type spring position, C type spring contraction also is stuck in the cannelure on locking bar, thereby realizes locking.Just in time be positioned at the groove of the inboard, hole of transparent outer cover with the projection on hour locking lever, avoided locking bar by revolving the problem that turning is back-outed comes.
By above-mentioned description, the relevant staff can, in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.Unaccomplished matter of the present utility model, belong to those skilled in the art's common practise.
