Description

Door lifter power failure self-locking device

Technical field

The utility model relates to a kind of door lifter power failure self-locking device, particularly relates to garage door door lifter power failure self-locking device, belongs to the garage door parts.

Background technology

The private savings garage that rises of sub-district, villa in recent years, however garage door is very important for the garage.In many cities, having a power failure becomes universal phenomenon, if garage door open or the way of closing the door in have a power failure suddenly, the door body can not self-locking, might cause the property of the inside, garage stolen like this.

Summary of the invention

The purpose of this utility model is to provide a kind of door lifter power failure self-locking device simple in structure, easy to use.

In order to address the above problem, the utility model is to be achieved through the following technical solutions: this door lifter power failure self-locking device, comprise clutch body, push rod, trace, pivot pin, clutch handle, clutch shuttle, spring, fixed head, guide rail, be set with self-lock pin on the fixed head on the clutch body, self-lock pin is to be integral by pivot pin and push rod, interlock, be drilled with self-locking hole on guide rail, described trace is balance self-lock pin and push rod, and spring housing is on push rod and trace.

During work, mainly be to pull down by clutch handle, manually close the door, the clutch shuttle is skidded off from clutch body, and push rod is return under the effect of spring, and the while self-lock pin is return also, clutch body is to the spacing place motion of closing the door, when closed the door in spacing place in arrival, self-lock pin enters under the effect of spring and carries out self-locking on the guide rail in the self-locking hole, thereby arrives a door body auto-lock function.

The advantage of this door lifter power failure self-locking device be simple in structure, easy manufacturing, safe and reliable, under the power failure garage door can not the situation of self-locking, can prevent that effectively the inside, garage property is stolen by manually locking a door.

Description of drawings

Fig. 1 does not have self-locking state figure for example of the present utility model;

Fig. 2 is example self-locking state figure of the present utility model;

Fig. 3 is the structural representation of self-locking hole on the guide rail.

The specific embodiment

Figure is further described the utility model below in conjunction with bowing: this door lifter power failure self-locking device, comprise clutch body 1, push rod 3, trace 4, pivot pin 5, clutch handle 6, clutch shuttle 7, fixed head 8, guide rail 9, spring 10, be set with self-lock pin 2 on the fixed head 8 on the clutch body 1, on guide rail 9, be drilled with self-locking hole 11, self-lock pin 2 is to be integral by pivot pin 5 and push rod 3, trace 4, described trace 4 is balance self-lock pin 2 and push rod 3, and spring 10 is enclosed within on push rod 3 and the trace 4.

As shown in Figure 1, do not having under the power-off condition, because self-lock pin 2 is integral by pivot pin 5 and push rod 3, trace 4, so clutch shuttle 7 backs down push rod 3, self-lock pin 2 also in fixed head 8 motions, is also backed down simultaneously, and at this moment self-lock pin 2 can not enter self-locking hole 11 on the guide rail 9.

As shown in Figure 2, when garage every body opening fully or the process of closing the door in when having a power failure, we can pull down by clutch handle 6, manually close the door, and clutch shuttle 7 is skidded off from clutch body 1, push rod 3 is return under the effect of spring 10, also return of self-lock pin 2 simultaneously, clutch body 1 be to the spacing place motion of closing the door, and arrives when closing the door spacing place, self-lock pin 2 enters under the effect of spring 10 and carries out self-locking on the guide rail 9 in the self-locking hole 11, thereby arrives door body auto-lock function.When coming the electric switch running body, clutch shuttle 7 enters in the clutch body 1 push rod 3 is backed down, and self-lock pin 2 is thrown off from self-locking hole 11 simultaneously, and door lifter normally moves with the door body.
