Embodiment

As shown in Figures 1 to 4, a kind of breeding house door lock mechanism provided by the utility model,

A kind of breeding house door lock mechanism, including handle assembly 1 and door catch component 2, the handle assembly 1 include being set to door-plate The front shoe 11 and the rear fixed plate 12 on the inside of door-plate 3 in 3 outsides, the front shoe 11 are equipped with front handlebar 13, institute It states rear fixed plate 12 and is connected equipped with rear handle 14, the front handlebar 13 and rear handle 14 by shaft 15, front handlebar 13 Rear end 131 extends to doorframe 4 in the horizontal direction, and the front shoe 11 is equipped with perpendicular with door-plate 3 close to one end of doorframe 4 Limit film 16, the limit film 16 are equipped with limit hole 161 compatible with the rear end 131 of front handlebar 13, the door catch component 2 Knocker inclined-plane 21 including being set to 4 outside of doorframe, the knocker inclined-plane 21 is equipped with compatible with the rear end 131 of front handlebar 13 The rear end 131 of knocker card slot 22, front handlebar 13 may pass through limit hole 161 and fall into knocker card slot 22.

The working principle of breeding house door lock mechanism provided by the utility model is as follows:

Handle assembly 1 and door catch component 2 are separately mounted on door-plate 3 and doorframe 4 (as shown in Figure 1), 13 He of front handlebar Handle 14 is connected by shaft 15 afterwards, and the front end of front handlebar 13 can rotate, the rear end 131 of front handlebar 13 in the horizontal direction to Doorframe 4 extends, and when shutdown, under the power of shutdown or inertia, the door in door catch component 2 is encountered in the rear end 131 of front handlebar 13 Button inclined-plane 21 is simultaneously moved upwards along knocker inclined-plane 21, when the rear end of front handlebar 13 131 moves at knocker card slot 22, preceding The rear end 131 of hand 13 front handlebar 13 itself gravity fall introduction buckle card slot 22 in, door lock can be lived, enabling when It waits, is lifted up front handlebar 13, knocker card slot 22 is left in the rear end 131 of front handlebar 13, and front handlebar 13 is separated with door catch component 2, Door can be opened；From the above process as it can be seen that the door lock mechanism of the utility model is without using spring, impact resistant capability is strong, Hand component 1 is installed on door-plate by front shoe 11, rear fixed plate 12 and shaft 15, and heat insulating ability is preferable, and this is practical new The door lock mechanism of type is actually keeper use to be done in the rear end 131 of front handlebar 13, therefore door lock mechanism has and touches i.e. lock function While energy, without additional setting keeper, structure is more simple.

As a preferred solution:

Shown in referring to figs. 2 and 3, the door catch component 2 includes the knocker fixed plate 23 set on 4 outside of doorframe, the door Button inclined-plane 21 is vertical in knocker fixed plate 23 (knocker inclined-plane 21 is parallel with limit film 16), and the knocker card slot 22 is set to door The top on inclined-plane 21 is detained, 22 opening upwards of knocker card slot are to fix on the top on knocker inclined-plane 21 close to knocker in the present embodiment One end of plate 23 is provided with notch, and notch and knocker fixed plate 23 collectively constitute knocker card slot 22, and structure is more simple.

In addition, knocker inclined-plane 21 in the present embodiment in door catch component 2 and knocker fixed plate 23 can integrated molding, installation When, it is only necessary to knocker fixed plate 23 is fixedly installed on doorframe 4,2 entirety of door catch component can be fixedly installed in doorframe 4 On, it installs more convenient.

Limit film 16 close to the side of door catch component 2 is connected with locking plate 17, and (flexible connection belongs to the public affairs of this field Know common sense, just no longer repeat one by one herein), the locking plate 17 is equipped with locking compatible with the rear end 131 of front handlebar 13 Hole 171, the rear end 131 of front handlebar 13 is also cross the limit hole 161 and lock hole 171 in limit film 16, front handlebar 13 It is rotated by limitation.

Referring to fig. 2 and shown in Fig. 4, the handle assembly 1 further includes padlock 18, on the locking plate 17 and limit film 16 Equipped with lock- receiving aperture 172/162 compatible with padlock 18.When shutdown, tumble lock stator 17 makes 171 sets of its lock hole preceding The rear end 131 of handle 13, the rear end 131 of front handlebar 13 also cross the limit hole 161 and lock hole 171 in limit film 16, and It falls into knocker card slot 22, front handlebar 13 is rotated by limitation at this time, and padlock 18 locks after passing through lock- receiving aperture 172/162, front handlebar 13 entirety are locked (as shown in Figure 4), can not be rotated, at this point, if necessary to open She Men, it is necessary to first open extension with key Lock 18 removes padlock 18, cancels the limitation to front handlebar 13, could open door, to play anti-theft function.Farm daytime When normal cultivation, padlock 18 can not have to, when rest, for the house door close to positions such as enclosure wall, roadsides, For the sake of security, padlock 18 is in use state.

In addition, in the utility model handle assembly 1 and door catch component 2 can the biggish material of use intensity be made, with Further enhance the impact resistant capability of door lock mechanism entirety.

In conclusion breeding house door lock mechanism provided by the utility model, of simple structure and low cost, it is easy for installation, no It needs spring to have and touches i.e. lock function, impact resistant capability is strong, compared with the existing technology, has conspicuousness progress, has and push away Wide application value.

It is last it is necessarily pointed out that: the foregoing is merely the preferable specific embodiments of the utility model, but this The protection scope of utility model is not limited thereto, and anyone skilled in the art discloses in the utility model In technical scope, any changes or substitutions that can be easily thought of, should be covered within the scope of the utility model.
