Abstract
The invention discloses a kind of lifting-handle-type vacuum chamber locking device, belong to mechanical lock field, include seat board, handle, connecting rod and wedge assemblies, described wedge assemblies includes fixing voussoir and the sliding wedge cooperated, the two ends of described connecting rod are connected with sliding wedge and handle respectively, one end of described handle is hinged with one end of seat board, described seat board, handle, connecting rod and sliding wedge composition quadric chain, it is additionally provided with tooth bar on described seat board, ratchet, described tooth bar and click-fit it is additionally provided with on described handle;The quadric chain of seat of the present invention forms self-locking for the first time when " dead point " position, fixing low-angle inclined-plane between voussoir and sliding wedge coordinates stroke to form second time self-locking, the ratchet mechanism (i.e. tooth bar and ratchet) of profile of tooth engagement forms third time self-locking, substantially increases self-locking reliability;It addition, the design of ratchet mechanism makes handle allow final position the most variable, enhance the use adaptability of device.
Description
Technical field
The present invention relates to mechanical lock field, particularly relate to a kind of lifting-handle-type vacuum chamber locking device.
Background technology
Existing mechanical handle lock is as the locking device of sealing door, and its version is varied.As a class merit
Lockset that can be the most special, its locking principle there is no too big difference with general lockset, is all to utilize to produce between dead bolt and snap close
Pretightning force lock door-plate and doorframe.Being summed up, the mechanism producing pretightning force is roughly divided into connecting rod and cam two class: connecting rod
Formula retaining mechanism mainly utilizes the dead-centre position of toggle to carry out self-locking, and connecting rod one end connects doorframe, and crank connects door
Plate, pulls door-plate to dead-centre position, is adjacent to doorframe self-locking after rotating crank;Cam-type retaining mechanism utilizes in cam pair exactly
The self-locking performance of angle of friction carries out self-locking, and common wedge shape dead bolt just belongs to this kind of retaining mechanism.
Existing as sealing the locking device of door, often have that self-locking reliability cannot be locked the most by force, stroke can not
The problems such as tune.Chinese Patent Application No. 201020568481.3, " fast-open " disclose one
Pressure vessel door locking device, although this patent have employed the multi-locking including " dead point " position, but this patent
Drive mechanism is complex, and self-locking reliability is poor, and is inconvenient to operate.
Summary of the invention
The purpose of the present invention is that a kind of lifting-handle-type vacuum chamber locking device of offer, to solve the problems referred to above.
To achieve these goals, the technical solution used in the present invention is such that a kind of lifting-handle-type vacuum chamber locking device, bag
Including seat board, handle, connecting rod and wedge assemblies, described wedge assemblies includes fixing voussoir and the sliding wedge cooperated, described
The two ends of connecting rod are connected with sliding wedge and handle respectively, and one end of described handle is hinged with one end of seat board, described seat board,
Hands, connecting rod and sliding wedge composition quadric chain, described seat board is additionally provided with tooth bar, described handle is additionally provided with spine
Pawl, described tooth bar and click-fit, tooth bar constitutes ratchet mechanism with ratchet.
As preferred technical scheme: the junction of one end of described handle and one end of seat board is by straight pin C and torsion
Spring is hinged.
Compared with prior art, it is an advantage of the current invention that:
1, self-locking reliability strengthens
Seat board, handle, connecting rod and sliding wedge composition quadric chain form self-locking for the first time, fixed wedge when " dead point " position
Low-angle inclined-plane between block and sliding wedge coordinates stroke to form second time self-locking, ratchet mechanism (the i.e. tooth bar of profile of tooth engagement
With ratchet) form third time self-locking, substantially increase self-locking reliability;
2, stroke is adjustable
Affecting due to sealing ring height on sealing surface, handle rotational travel final position has certain deviation, but ratchet mechanism
Design make its allow final position the most variable, enhance the use adaptability of device.
3, easy to operate
The handle-type drag hook of the present invention, meets the operating habit of operator, more convenient operation.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment:
Seeing Fig. 1 and Fig. 2, a kind of lifting-handle-type vacuum chamber locking device, including seat board 1, handle 2, connecting rod 4 and wedge assemblies 3, wedge
Block assembly 3 includes fixing voussoir and the sliding wedge cooperated, and wherein the structure of sliding wedge is as it is shown on figure 3, the two of connecting rod 4
Holding hinged with sliding wedge and handle 2 respectively, one end of one end of handle 2 and seat board 1 is cut with scissors by torsion spring 8 and 12, straight pin C12
Connect, seat board 1, handle 2, connecting rod 4 and wedge assemblies composition quadric chain, seat board 1 is additionally provided with tooth bar 6, its structure such as Fig. 4
Shown in, tooth bar 6 is connected by hexagon socket cap head screw 9 is fixing with seat board 1, and handle 2 is additionally provided with ratchet 7, and its structure is such as
Shown in Fig. 5, ratchet 7 is connected by straight pin A10, straight pin B11, and straight pin A10, straight pin B11 load its two ends after handle 2
Jumping-up or center-punching, prevent abjection;Tooth bar 6 coordinates with ratchet 7, and tooth bar 6 and ratchet 7 constitute ratchet mechanism.
When installing and using, seat board 1 is connected by screw fixing with the door-plate of vacuum chamber, fixing voussoir and drag hook 5 then with very
The doorframe (not shown) of empty room connects fixing;
As it is shown in figure 1, lift handle 2 when making folding, connecting rod 4 then drives sliding wedge to move up and down, with fixing voussoir by little
Gradient inclined-plane is the most sealed, then engages formation ratchet mechanism by profile of tooth between ratchet 7 with tooth bar 6, prevents handle 2 from disengaging to increase
The reliability of feeder apparatus self-locking;
When the position of the ratchet 7 holding handle 2, after making ratchet 7 rotation disengagement tooth bar 6 release self-locking, lift handle 2 and pass through connecting rod
4 pull sliding wedge to move up so that it is disengage with fixing voussoir, and door just can be opened, otherwise is then locked;
The profile that is slidably matched preferably formed at fixing voussoir and sliding wedge smears moderate lubrication fat, to ensure smooth and easy nothing of moving
Retardance.
The present invention is not disclosed technology and belongs to general knowledge as well known to those skilled in the art.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit this present invention, all in this present invention
Spirit and principle within any amendment, equivalent and the improvement etc. made, should be included in this protection scope of the present invention
Within.
