[specific embodiment]
The utility model is a kind of plug-type latch, as shown in Fig. 1,3,4, includes the buckle 10 being arranged on doorframe and is arranged on the lock pin assembly on door leaf, described lock pin assembly includes hollow latch face-piece 20, in described latch face-piece 20, being provided with one can stretch out latch face-piece 20 and sell the pin tongue 30 in buckle 10, upper surface at described latch face-piece 20 has a patchhole 21, above described latch face-piece 20, be fixed with a handles support 40, in the upper end of described handle supporting 40, be provided with a rotation central axis 80, on described rotation central axis 80, be provided with a bending handle 50, described handle 50 is provided with the axis hole 51 being socketed on rotation central axis 80 at bending part, described handle 50 is divided into handshake part 52 and the swing part 53 at bending part two ends, described swing part 53 is connected with pin tongue 30 and can passes in and out buckles 10 by Level Promoting pin tongue 30 front ends through the patchhole 21 of latch face-piece 20, the distance of described patchhole 21 rear and front ends meets handle swing part 53 and swings and orders about pin tongue 30 front ends and stretch out the scope of inserting buckle 10 or retreating retraction latch face-piece 20, thus so just can make handle 50 by above draw or under push away and around rotation central axis 80 rotations, make swing part 53 controls of handle sell tongues 30 in latch face-piece 20, to advance and stretch into that the interior realization of buckle 10 is locked a door or backed off after random buckle 10 is realized release.
Before using the utility model, be first arranged on doorframe and door leaf, be that buckle 10 is arranged on doorframe, lock pin assembly is arranged on door leaf, at this, the opposite direction (as shown in Figure 3,4) of the direction that stretch out handle handshake part 52 and buckle 10.When door need to pin, as long as after making handle rotate around rotation central axis 80 on the handshake part 52 at handle 50, by swing part 53, driving connected pin tongue 30 to make pin tongue 30 stretch out latch face-piece 20 in the interior horizontal slip of latch face-piece 20 is inserted in the buckle 10 on doorframe, has completed the locking of door; When door needs release, as long as pull out the handshake part 52 of catching handle 50, handle 50 rotates around rotation central axis 80 immediately, the swing part 53 of handle 50 swings and retreats thereupon in the scope of latch face-piece 20 patchholes 21, like this, the swing part 53 of handle 50 just drive connected pin tongue 30 in latch face-piece 20 backward level slide and make it exit buckle 20 to be retracted in latch face-piece 20, to have completed unblanking of door, then continue to pull handshake part 52 to open the door.
As seen from the above, the utility model is by being bent into the handle of handshake part 52 and swing part 53, drive the pin tongue 30 front and back horizontal slips that are connected with handle swing part 52 in latch face-piece 20, making pin tongue 30 can stretch out latch face-piece 20 is inserted in buckle 10 or exits buckle 10 and be retracted in latch face-piece 20, reach the object of door locking or unlocking, and after unblanking, continue to pull handshake part 53 just can open door, therefore the utility model unites two into one latch and handle, it is rational in infrastructure, simple to operate, convenient and practical, save use cost.
For anti-shotpin tongue 30 produces and becomes flexible at pinning state, also guarantee that pin tongue 30 can not stretch out latch face-piece 20 and hurt sb.'s feelings when released state, so, between described pin tongue 30 and latch face-piece 20, be provided with location structure.In the present embodiment, as Fig. 1, 2, 3, shown in 4, described location structure comprises the Location resilient piece 70 that is nested in the drain pan 60 that latch face-piece 20 is interior and latch face-piece 20 is fixing and is fixed on pin tongue 30 soffits, on described Location resilient piece 70, be provided with release groove 71 and latch groove 72, the soffit of described drain pan 60 be provided with can with Location resilient piece 70 on release groove 71, the boss 61 that latch groove 72 matches, described boss 61 can guarantee that the rear pin tongue 30 of its latch groove 72 on falling into Location resilient piece 70 can be inserted in buckle 10, it can be retracted in latch face-piece 20 completely dropping into the rear pin tongue of release groove 71, at this, release groove 71, it between latch groove 72 and boss 61, is upper and lower concavo-convex cooperation.Certainly, also can on Location resilient piece 70, be provided with two outwardly projections, on drain pan 60, be provided with a groove matching with projection and realize concavo-convex cooperation location.
Can be in the interior horizontal slip of latch face-piece 20 under handle swing part 52 is controlled in order to realize pin tongue 30, as Fig. 1, 3, in embodiment shown in 4, the swing part 52 being provided with for handle 50 at described pin tongue 30 upper surfaces inserts and pulls pin tongue 30 at the horizontal sliding jack 31 of latch face-piece 20 interior front and back horizontal slip, due to horizontal sliding jack 31 wider (wide than swing part thickness), the swing part 52 that has guaranteed handle 50 has enough swinging distances in horizontal sliding jack 31, be unlikely to, in the process swinging, pin tongue 30 is taken away to horizontal plane, certainly, also can realize by other structures, as respectively opened a corresponding vertical slot in pin tongue 30 both sides, on the position of corresponding two vertical slots of swing part 52 of handle 50, be respectively provided with one and be inserted into locating shaft fixing in vertical slot, when slide swing part 52 band untie-sell tongue 30 front and back of handle 50, the vertical slot of pin tongue 30 provides swinging distance just to the swing part 52 of handle 50.
In the present embodiment, as shown in Fig. 1,3,4, described handle supporting 40 is triangle three-dimensional bracket, include the fixing fixed head 41 of below and the upper surface of latch face-piece 20 and minute stand in before and after the side plate 42 of both sides, certainly, also can be tetragonal three-dimensional bracket, as long as middle part sets up an axis of rotation that can pass the axis hole 51 of handle 50 bending parts also to supply handle 50 around its rotation in the top.
Although reference above embodiment describes the utility model in detail, but it will be apparent to one skilled in the art that by the disclosure, and in the situation that do not depart from principle of the present utility model and the spiritual scope that described claim limits, can the utility model be made a variety of changes or be revised.Therefore, the detailed description of disclosure embodiment is only used for explaining, rather than is used for limiting the utility model, but is defined by the subject-matter of the claims the scope of protection.
