Description
Technical field
The present invention relates to a kind of latch assembly, belong to hardware-joint technical field.
Background technology
Latch is as a kind of conventional hardware-joint; no matter in daily life, or often use in some box work or equipment, existing common latch; mainly it is made up of bolt rod, Fixed latches cover for seat and the socket that matches with bolt rod; its structure is relatively simple, and the fastness of grafting is poor, closes or open underaction, speed slow; poor reliability; in-convenience in use, easily accidentally injure the hands of user, poor practicability.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, and provide a kind of simple in construction, easy to use, reliable, switch is flexible, the latch assembly that grafting fastness is strong.
It is an object of the invention to complete by following technical solution, it is mainly made up of the socket that a latch and are supporting, described latch includes the afterbody bolt rod with handle, this bolt rod is coated with a Fixed latches cover for seat, at least spring being nested with on bolt rod is installed in Fixed latches cover for seat, one end of described spring compresses in Fixed latches cover for seat, and the other end is pressed on bolt rod on the check ring arranged；The head of described bolt rod is horizontally arranged with at least one projection；It is provided with one on described socket and is available for the jack that bolt rod head inserts, and on the perisporium of described jack, be provided with a L-shaped slot inserted along the projection that vertically starts to extend internally, is available for from jack end edge.
Divide in described Fixed latches cover for seat and two springs are installed up and down, a middle springs back-up ring it is provided with in Fixed latches cover for seat between two springs, separately the plug housing that is relatively fixed at described bolt rod overlaps up and down, is respectively arranged with the upper check ring and lower spring back-up ring compressed for upper spring and lower spring.
The afterbody of described bolt rod is provided with the lever-like handle being bent into 90 degree；Fixed plate or the fixed block of band fixing hole it is provided with on the outer wall of described Fixed latches cover for seat.
The head of described bolt rod is horizontally arranged with two projections being arranged symmetrically with, and is correspondingly provided with the L-shaped slot that two be arranged symmetrically with insert for two projections respectively on the perisporium of described jack.
A kind of night bolt of the present invention, is a kind of improvement to prior art, and it has simple in construction, easy to use, reliable, switchs flexibly, the features such as grafting fastness is strong.
Accompanying drawing explanation
Fig. 1 is the perspective view of the present invention.
Fig. 2 is the structural representation of the present invention.
Fig. 3 is the A A sectional structure schematic diagram of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is done shown in detailed introduction: Fig. 1,2,3, the present invention is mainly made up of a latch 1 and a supporting socket 2, described latch 1 includes the afterbody bolt rod 12 with handle 11, this bolt rod 12 is coated with a Fixed latches cover for seat 3, at least spring being nested with on bolt rod 12 4 is installed in Fixed latches cover for seat 3, one end of described spring 4 compresses in Fixed latches cover for seat 3, and the other end is pressed on bolt rod 12 on the check ring 13 arranged；The head of described bolt rod 12 is horizontally arranged with at least one projection 14；It is provided with one on described socket 2 and is available for the jack 21 that bolt rod 12 head inserts, and on the perisporium of described jack 21, be provided with a L-shaped slot 22 inserted along the projection that vertically starts to extend internally, is available for from jack end edge.
Shown in figure, divide in described Fixed latches cover for seat 3 and two springs 4 are installed up and down, a middle springs back-up ring 31 it is provided with in Fixed latches cover for seat 3 between two springs 4, another it is relatively fixed latch cover for seat 3 about at described bolt rod 12, is respectively arranged with the upper spring 41 of confession and upper check ring 131 that lower spring 42 compresses and lower spring back-up ring 132.
The afterbody of described bolt rod 12 is provided with the lever-like handle 11 being bent into 90 degree；Fixed plate 33 or the fixed block of band fixing hole 32 it is provided with on the outer wall of described Fixed latches cover for seat 3.
The head of bolt rod 12 of the present invention is horizontally arranged with two projections 14 being arranged symmetrically with, and is correspondingly provided with the L-shaped slot 22 that two be arranged symmetrically with insert for two projections respectively on the perisporium of described jack 21.
During use, by the most supporting to Fixed latches cover for seat 3 and socket 2 fixing, under normal condition, under the action of the spring, its head leaves socket 2 to bolt rod 12, is in latch open mode；When needing to close (grafting), by handle pressing bolt bar 12, in the case of overcoming spring force, the head of shank 12 inserts in the jack 21 of socket 2, and the projection 14 of shank head enters in the vertical channel in L-shaped slot 22 therewith, and plays a kind of guide effect, after projection 14 is inserted into bottom vertical channel, making shank rotate by handle 11, projection 14 enters the level trough in L-shaped slot 22 therewith, thus realizes locking latch function.Otherwise, when latch opened by needs, as long as by handle 11 rotary insertion extension bar, projection 14 being proceeded to from level trough vertical channel, now, because being acted on by spring force, shank automatic retracted, leaves socket, it is achieved opening.
