Description

Door and window locking window catch

Technical field

The utility model relates to a kind of door and window locking device, and the spacing retaining mechanism that especially a kind of movable window low-angle is opened belongs to the hardware ﹠ tools technical field.

Background technology

Vehicle must satisfy the interior personnel's of shelter of sealing air-conditioning requirement when the state of enforcement, the method for general head it off is by opening the mode of movable window.At present, shelter movable window unlatching form mainly contains: type of push and pull up down, about move pull-type, upper-turn-type and laterally opened.Though preceding two kinds of form activity windows can be opened in vehicle running state, but in the shelter that the electromagnetic shielding requirement is arranged, can't use, though the two kinds of form activity windows in back can satisfy the electromagnetic shielding requirement of shelter, but the movable window of upper-turn-type can not wide-angle open and use (trafficability characteristic that influences vehicle) in vehicle running state, laterally opened movable window will be opened in vehicle running state, then must open 180 ° spacing on the shelter outer wall, personnel want in vehicle running state the switch window, and both inconvenience was more dangerous.So need a kind of can be conveniently laterally opened or spacing retaining mechanism that upper-turn-type movable window low-angle is opened to shelter, realize vehicle under the condition that does not influence trafficability characteristic, personnel's air-conditioning requirement in the shelter when satisfying driving states.

The utility model content

The purpose of this utility model provides the spacing retaining mechanism that a kind of movable window low-angle is opened, and can satisfy the electromagnetic shielding requirement of shelter, personnel's air-conditioning requirement in the shelter in the time of satisfying driving states again.

The utility model is achieved by the following technical programs:

A kind of door and window locking window catch comprises stopping means and positioner, and stopping means is fixed on the window frame, and positioner is fixed on the movable window, and described stopping means comprises base, positive stop hook, rotating shaft, and an end of described base and positive stop hook flexibly connects; Described positioner comprises hook seat and shackle, and described shackle is vertically fixed on the middle part of hook seat.

The purpose of this utility model can also further realize by following technical measures.

Aforesaid door and window locking window catch, an end of wherein said rotating shaft is fixedlyed connected with an end of positive stop hook, the other end of described rotating shaft and base flexible connection, another termination of described rotating shaft be axially arranged with several planes.

Aforesaid door and window locking window catch also is provided with torsion spring in the wherein said base, an end of described torsion spring is resisted against in the base, and the other end of described torsion spring is resisted against on the plane of rotating shaft termination.

The utility model compact conformation, convenient to operation, the locking better reduction, easy for installation.The utility model can use in the shelter that the electromagnetic shielding requirement is arranged, and can guarantee during use that under driving states personnel have good ventilation condition in the shelter, can guarantee that the complete sum of windowsill is attractive in appearance simultaneously, helps the setting of the switch and the screen window of curtain.

Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As Fig. 1～shown in Figure 5, the utility model comprises stopping means 1 and positioner 2.Stopping means 1 by screw on window frame, positioner 2 by screw on movable window.Stopping means 1 comprises base 11 and positive stop hook 12, one end of rotating shaft 13 is fixedlyed connected with an end of positive stop hook 12, the other end of rotating shaft 13 and base 11 flexibly connect, another termination of rotating shaft 13 be axially arranged with several planes 131, the termination of present embodiment is square, 4 planes 131 are arranged, rotating shaft 13 is arranged on the center of base 11, nut 17 screws in rotating shaft 13, the centre of base 11 also is provided with sagging groove 16, one end 121 of positive stop hook 12 can rotate 90 ° around the rotation of the center of base 11 together with rotating shaft 13 at every turn, and base 11 is provided with two through holes that are connected with window frame 15.

Positioner 2 comprises hook seat 21 and shackle 22, and shackle 22 is vertically welded in the middle part of hook seat 21, and the other end 122 of positive stop hook 12 is hooked in the shackle 22, and the hook seat is provided with two through holes that are connected with movable window 23.Also be provided with torsion spring 14 on the base 11, an end of torsion spring 14 is resisted against in the base 11, and the other end of torsion spring 14 is resisted against on the plane 131 of rotating shaft termination, and like this, positive stop hook can only rotate 90 ° at every turn.

The utility model is the spacing retaining mechanism that a kind of movable window low-angle is opened, and is used for upper-turn-type or low-angle location of laterally opened movable window and locking.During use, positive stop hook 12 to rotating out of my cabin, is outwards touched movable window to certain angle simultaneously, the front end of positive stop hook 12 is colluded in the shackle 22, can realize the low-angle unlatching of movable window spacing, this moment positive stop hook 12 be in level, as shown in Figure 5.Like this, the trafficability characteristic of vehicle under the driving states can be satisfied, the air-conditioning requirement of personnel in the cabin can be satisfied again.During release, only need positive stop hook 12 is taken out from shackle 22, under the resilient force of spring 14, positive stop hook 12 is in vertical state, as shown in Figure 4.

In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
