LIFTING AND OVERTURNING TYPE AUTOMATICALLY-LOCKED PET CAGE DOOR

Abstract

A lifting and overturning type automatically-locked pet cage door includes a lifting handle, a hook shift liver, a spring, a rotting shaft and a pair of guide rails. The lifting handle is rotatably fixed on the upper end of a door body, and the hook shift lever is fixed on a crossbar above the door body; when the cage door is closed, the hook shift lever hooks the upper end of the door body under the action of the spring to realize locking; when the cage door is opened, the door body slides upwards along a pair of guide rails to drive the hook shift lever to rotate, and slides upwards to the maximum displacement position after being separated from the hook shift lever, and the door body rotates along the rotating shaft and is laid on the top of the pet cage.

Claims

1. A lifting and overturning type automatically-locked pet cage door, comprising: a lifting handle (1); a hook shift lever (2); a spring (3); a rotating shaft (4); and a pair of guide rails (5), wherein the lifting handle (1) is rotatably fixed on the upper end of a door body, and the hook shift lever (2) is fixed on a crossbar above the door body; wherein when the cage door is closed, the hook shift lever (2) hooks the upper end of the door body under the action of the spring (3) to realize locking; and wherein when the cage door is opened, the door body slides upwards along a pair of guide rails (5) to drive the hook shift lever (2) to overcome the elastic force of the spring (3) to rotate, and slides to the maximum displacement position upwards after being separated from the hook shift lever (2), and the door body rotates along the rotating shaft (4) and is laid on the top of the pet cage.

2. The lifting and overturning type automatically-locked pet cage door according to claim 1, wherein the spring (3) is a torsional spring.

3. The lifting and overturning type automatically-locked pet cage door according to claim 1, wherein the pair of guide rails (5) are vertically positioned on both sides of the door body.

4. The lifting and overturning type automatically-locked pet cage door according to claim 1, wherein the door body is rectangular.

5. The lifting and overturning type automatically-locked pet cage door according to claim 1, wherein the guide rails (5) are square guide rails.

DETAILED DESCRIPTION

[0023] The present invention is further illustrated as below in conjunction of attached drawings and specific embodiments.

[0024] By reference to FIG. 1 to FIG. 5, a lifting and overturning type automatically-locked pet cage door comprises a lifting handle 1, a hook shift lever 2, a spring 3, a rotating shaft 4 and a pair of guide rails 5; the lifting handle 1 is rotatably fixed on the upper end of a door body, and the hook shift lever 2 is fixed on a crossbar above the door body; when the cage door is closed, the hook shift lever 2 hooks the upper end of the door body under the action of the spring 3 to realize locking; and when the cage door is opened, the door body slides upwards along a pair of guide rails 5 to drive the hook shift lever 2 to overcome the elastic force of the spring 3 to rotate, and slides to the maximum displacement position upwards after being separated from the hook shift lever 2, and the door body rotates along the rotating shaft 4 and is laid on the top of the pet cage.

[0025] By reference to FIG. 2 to FIG. 3, the spring 3 may be a torsional spring.

[0026] By reference to FIG. 4 to FIG. 5, the pair of guide rails 5 may be vertically positioned on both sides of the door body.

[0027] By reference to FIG. 1 and FIG. 4, the door body may be rectangular.

[0028] By reference to FIG. 2 and FIG. 5, the guide rails 5 may be square guide rails.

[0029] The lifting and overturning type automatically-locked pet cage door disclosed by the present invention is capable of realizing automatic unlocking and very labor-saving to operate; actions of unlocking and opening the door of the pet cage are coherent and convenient to operate; no bolt needs to be used, so that parts of the bolt are reduced, and the phenomenon of lost of parts cannot happen; the guide rails on both sides are capable of sliding up and down, so that the space is saved; when the pet cage door is opened, the door body can be flatly laid on the upper part of the cage, so that the space is saved, and thus the cage door is more convenient to be opened and closed.
