Abstract

A ground lock device of rolling shutter door comprises a cam lock-head component which is installed on the middle section of the rolling shutter door bottom and a lock hole which is fixed and inserted on the ground. The utility model is characterized in that: the rolling shutter door is locked by means that the lock-head cam (13) driven by a continuous move mechanism of the rolling shutter door lock rotates to the underside of the boss (16) in the lock hole. The utility model is simple in structure and convenient to install and use.

Description

A kind of rolling door ground locking device

The utility model relates to a kind of door lock assembly, particularly rolling door ground locking device.

Rolling door is used for people such as the shop front frequent place of coming in and going out more, be the convenience that does not hinder people to come in and go out, rolling screen door lock design all be two ends at the bottom of the lock door, because of the rolling door span wide, normal occur because of the burglar lift with the pry sled at the bottom of the middle part, arching is to two ends locking bar slippage and door is opened stolen problem at the bottom of making.

The purpose of this utility model provides and a kind ofly makes that the middle part also can lock at the bottom of the rolling door, and Men Kaihou does not hinder the rolling door ground locking device of people's easy access.

The purpose of this utility model is achieved in that a cam lock head component is installed at the middle part at the bottom of rolling door, and its cam partly vertically stretches out at the bottom of the rolling door, driving mechanism and rolling screen door lock interlock.At surface drilling corresponding to cam tapered end position, lockhole body of plane earth setting-in for inner convex platform.When rolling door shut, the tapered end cam inserted in the lockhole, and the tapered end cam is turned back under the boss in the lockhole body with the door lock lock out action, thereby has realized the also purpose of locking of rolling door middle part, because of lockhole is the plane earth setting-in, and does not hinder the convenience that people come in and go out.

The rolling door ground locking device that the utility model constitutes, because of having locked middle part, the door end reliably, arching can not lifted because of sled in the middle part at the bottom of the rolling door, the stolen problem so prevented effectively therefore, the utility model is simple in structure, and is reasonable in design, uses to install all to make things convenient for.

Be that the utility model is described in further detail for example and embodiment below with the accompanying drawing:

Fig. 1 is the sectional view of first embodiment of the present utility model.

Fig. 2 is the tapered end transmission mechanism partial view of the utility model Fig. 1.

Fig. 3 is the sectional view of second embodiment of the present utility model.

Fig. 4 is the tapered end transmission mechanism partial view of the utility model Fig. 3.

Fig. 5 is the locking part partial view of the utility model Fig. 1, Fig. 3.

As Fig. 1, Fig. 2, shown in Figure 5, rolling door ground locking device is actively connected on the tapered end seat 10 through seat hole 11 by tapered end 1 usefulness nut 3, nut 5 and the spacer ring 4 of strap cam 13.Connecting hole 12 is arranged on the tapered end seat 10, with nut 2 and nut 3 interlock plate 9 is housed on the tapered end 1, interlock plate 9 by pin 6 through slipping ring 7 and shift fork 8 active be connected etc. form lock head component with by the oval lockhole 15 of coming in and going out for tapered end cam 13, the inner convex platform 16 of control tapered end cam 13, the lockhole body 14 that annular chamber 17 and screw 18 constitute is formed.

Fig. 3, Fig. 4 have provided the transmission mechanism of another kind of driving tapered end cam.On tapered end 1, gear 21 is housed, is engaged with tooth bar 22, location-plate 19 with ellipse garden slotted hole 20 is housed at

tapered end

1 and 22 of tooth bars with gear 21 with nut 3 and nut 5.On tooth bar 22 and the location-plate 19 connecting hole 23 is arranged.

During use, appropriate location with bolt middle part at the bottom of the connecting hole on the tapered end seat 10 12 is packed in rolling door with lock head component, at surface drilling corresponding to tapered end cam 13 positions, come tightening setting-in lockhole body 14 with expansion bolt or cement casting bolt, make lockhole body 14 upper surfaces concordant with ground.The rolling door of leaving behind is to shutting the position, makes tapered end cam 13 insert the lockhole bodies, after turn nut 3, nut 5 are adjusted tapered end cams 13 and can be turned round freely in the annular chamber 17 of lockhole body 14 with its locking.Pull-up rolling door slightly, when making tapered end cam 13 in ellipse garden shape lockhole 15, mate contraposition on a horizontal plane, shift fork 8 (or tooth bar 22) is connected with the interlinked mechanism of rolling screen door lock in the enable possition, like this, when in using, closing rolling door, tapered end cam 13 is just inserted in the lockhole body 14 by hole, ellipse garden 15, closing motion along with rolling screen door lock, shift fork 8 makes tapered end cam 13 return back to the inner convex platform 16 times of lockhole body 14 through slipping ring 7, pin 6, interlock plate 9 (or tooth bar 22 is through gear 21), makes the rolling door middle part also locked.

Claims

1, a kind of rolling door ground locking device, form by lock head component that connects at the bottom of the rolling door and the lockhole body that is flush-mounted in ground, it is characterized in that: the tapered end (1) of strap cam (13) nut (3), nut (5) and spacer ring (4) are actively connected on the tapered end seat (10) through seat hole (11).By the ellipse garden shape lockhole (15) of coming in and going out for tapered end cam (13), the inner convex platform (16) of control tapered end cam (13), the lockhole body (14) that annular chamber (17) and screw (18) constitute.A tapered end transmission mechanism is arranged on the tapered end (1).

2, rolling door according to claim 1 ground locking device is characterized in that this tapered end transmission mechanism is interlock plate (9) via pins (6) that is connected tapered end (1) top, slipping ring (7) and active connection of shift fork (8).

3, rolling door according to claim 1 ground locking device, it is characterized in that this tapered end transmission mechanism is the gear (21) and tooth bar (22) engagement that is connected tapered end (1) top, is equipped with the location-plate (19) with ellipse garden slotted hole (20) between tapered end (1) and tooth bar (22).
