Abstract
The invention relates to a locking device for preventing error opening. The locking device comprises a tank body, a cover plate and a locking device body; the tank body is a box with an opening in the upper end, the cover plate is in a plate shape, a cover plate edge perpendicular to the cover plate is arranged at the edge of the cover plate, and a ring of groove corresponding to a sliding block groove is formed in the inner side of the cover plate edge; the locking device body comprises a plurality of sliding blocks evenly distributed on the periphery of the opening of the box and a gear mechanism arranged on the cover plate; the sliding blocks are horizontally arranged in the sliding block groove in the opening of the box; the gear mechanism comprises a gear shaft perpendicularly penetrating the cover plate, a gear arranged at the tail end of the gear shaft and a plurality of racks matched with the gear; and a protrusion matched with a clamping groove is arranged at the tail end of each rack. The locking device has the advantages that the sliding blocks are driven by the gear mechanism, locking and looseness of the box and the cover plate are achieved, the structure is simple, and fixation is firm.
Description
Technical field
The present invention relates to a kind of locking field, particularly a kind of latching device preventing by mistake opening.
Background technology
Be locked at a lot of field all to have a wide range of applications, but existing latching device is multifarious, shape is very strange, and it is slow also to deposit locking in a particular application, locks insecure.The problem that complex structure cost is high.
Summary of the invention
It is simple that the technical problem to be solved in the present invention is to provide a kind of structure, locks the latching device of firmly manual unlocking.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of latching device preventing by mistake opening, and its innovative point is: comprise casing, cover plate and latching device body,
Described casing is the box body that a upper end has opening, and described open outer side has the step that a circle is offered to box inside, and this opening surrounding has uniform slide block slot;
Described cover plate is a tabular, and its edge has the cover plate limit that vertical cover plate is arranged, and has the circle groove corresponding with slide block slot inside described cover plate limit, and tops bar with casing bottom this cover plate limit and match;
Described latching device body comprises some slide blocks being distributed on box opening surrounding and the gear mechanism arranged on the cover board; Described slide block is horizontally set in box opening top shoe groove, and its head stretches out casing outside, and its afterbody gos deep into box inside, and its afterbody has a draw-in groove; Described gear mechanism comprises a gear wheel shaft, vertically running through cover plate setting and is arranged on the gear of gear wheel shaft end and some tooth bars coordinated with gear; Described tooth bar end has a projection coordinated with draw-in groove.
Further, described gear wheel shaft upper end has one handle.
Further, described slide block has one and be fixed on spring in slide block slot.
Further, described slider head upper end is an inclined-plane.
The invention has the advantages that: utilize gear mechanism band movable slider, realize the locking of casing and cover plate and get loose, structure is simple, fixation.
Accompanying drawing explanation
Fig. 1 is a kind of casing birds-eye view preventing the latching device by mistake opened of the present invention.
Fig. 2 is a kind of cover plate schematic diagram preventing the latching device by mistake opened of the present invention.
Detailed description of the invention
As shown in Figure 1, the invention discloses a kind of latching device preventing by mistake opening, comprise casing 1, cover plate 3 and latching device body, casing 1 is the box body that a upper end has opening, open outer side has the step that a circle is offered inside casing 1, and this opening surrounding has uniform slide block slot; Cover plate 3 is in a tabular, and its edge has the cover plate limit that vertical cover plate 3 is arranged, and has the circle groove corresponding with slide block slot 2 inside cover plate limit, and tops bar with casing 1 bottom this cover plate limit and match; Latching device body comprises some slide blocks 4 being distributed on box opening surrounding and the gear mechanism be arranged on cover plate 3; Described slide block is horizontally set in box opening top shoe groove, and its head stretches out casing outside, and its afterbody gos deep into box inside, and its afterbody has a draw-in groove; Gear mechanism comprises a gear wheel shaft 7, vertically running through cover plate setting and is arranged on the gear 11 of gear wheel shaft 7 end and some tooth bars 10 coordinated with gear 11; Tooth bar 10 end has a projection coordinated with draw-in groove.
During use, projection on tooth bar 11 is aimed at the draw-in groove on slide block 4, cover plate 3 is placed into the opening part of casing 1, first cover plate limit touches slide block 4, and slide block 4 head is an inclined-plane, cover plate limit compressing slider head, under force, in slide block 4 indentation slide block slot, cover plate limit is slided, and coordinates with casing step; Slide block 4 puts in the groove 2 on cover plate limit under spring force, realizes locking;
When opening, turning handle 8, rotating shaft driven gear 11, carry-over bar 10 is with by gear 11, and the draw-in groove heavy keying fit on the projection on tooth bar 10 and slide block 4, movable slider 4 is with by tooth bar 10, and slide block 4 indentation slide block slot, cover plate 3 namely can smooth opening.
More than show and describe groundwork of the present invention and principal character.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
