[0029] The following disclosure provides many different implementation methods or examples for different ways of implementing this utility model.

[0030] See attached document Figure 1 To be continued Figure 6 As shown, a safety gate includes a fabric roll tube 1, a mesh fabric 2 sleeved on the fabric roll tube 1, a pull rod 3, a mesh fabric rewinding device, and a switch assembly 5 that can unlock or lock the mesh fabric rewinding device, wherein the pull rod 3 is fixedly connected to the stretched end of the mesh fabric 2.

[0031] In one embodiment of this utility model, the mesh rewinding device includes a central tube disposed inside the fabric rewinding tube 1, a fabric rewinding spring sleeved on the central tube, and a fixing tooth 41 fixedly connected to one end of the central tube. The outer circumference of the fixing tooth 41 is provided with a plurality of locking teeth at intervals. The separating member 53 is provided with a limiting tooth 532 that can engage with the locking teeth on the side near the fixing tooth 41. After the user completes the stretching operation of the mesh 2, the separating member 53 will engage with the fixing tooth 41 under the action of the first return spring 54, thereby completing the locking operation of the mesh rewinding device.

[0032] In one embodiment of the present invention, the switch assembly 5 includes a pressing member 51, a flat pushing member 52 that can be engaged with the pressing member 51, a separating member 53 that can be engaged with the fixed toothed member 41, and a second return spring 55. The separating member 53 is provided with a first return spring 54 on the side away from the fixed toothed member 41. The unlocking or locking operation of the mesh rewinding device can be completed through the switch assembly 5.

[0033] In one embodiment of this utility model, the side of the flat push member 52 away from the fixed tooth member 41 is provided with an inclined surface 521 that can abut against one end of the separating member 53. This allows the flat push member 52 to be unlocked after the pressing member 51 is pressed down. Then, while moving the flat push member 52, the inclined surface 521 can be used to move the separating member 53 away from the fixed tooth member 41, thus completing the unlocking operation of the mesh rewinding device. After the stretching operation of the mesh 2 is completed, the separating member 53 will engage with the fixed tooth member 41 under the action of the first return spring 54, thereby completing the locking operation of the mesh rewinding device. This not only makes the operation simple, but also significantly improves the practicality and safety.

[0034] In one embodiment of this utility model, the two ends of the fabric rolling tube 1 are respectively provided with an upper mounting seat and a lower mounting seat. One end of the central tube is fixed to the lower mounting seat with a screw, and the lower spring buckle is fixed to the central tube with a screw. One end of the fabric rolling spring is hooked on the lower spring buckle, and the other end is hooked on the inner spring buckle. The other end of the central tube 2 is fixed to the column inside the upper mounting seat with the same type of screw, thereby realizing the stretching and rewinding action of the mesh fabric 2.

[0035] In one embodiment of the present invention, the upper mounting base includes a lower housing 61 and an upper housing 62 connected to the lower housing 61 by screws. The surface of the upper housing 62 is provided with a through hole through which the top of the push member 52 can pass. After the push member 52 is unlocked by pressing down the pressing member 51, the push member 52 can be moved through the through hole.

[0036] In one embodiment of this utility model, the lower mounting base includes a lower base 71 fixedly connected to the central tube and a spring inner buckle and a spring lower buckle respectively disposed at both ends of the fabric rolling spring. One end of the separating member 53 is rotatably connected to the lower housing 61, and the other end of the separating member 53 is provided with a vertical protrusion 531 that can abut against the inclined surface 521. Thus, when the pushing member 52 is unlocked and moved, the vertical protrusion 531 can be pushed under the action of the inclined surface 521, thereby driving one end of the separating member 53 to perform an unlocking operation away from the fixed tooth member 41.

[0037] In one embodiment of this utility model, a limiting groove 522 is vertically provided on one side of the top of the flat push member 52, and a protrusion 511 that can be inserted into the limiting groove 522 is provided on one side of the pressing member 51. The second reset spring 55 is partially disposed in the pressing member 51, so that the flat push member 52 can be unlocked after pressing the pressing member 51. After the stretching operation of the mesh 2 is completed, the pressing member 51 can be released and it can rebound under the action of the second reset spring 55 to complete the translational limitation of the flat push member 52.

[0038] In one embodiment of this utility model, the two ends of the pull rod 3 are respectively provided with an upper handrail hook seat 8 and a lower handrail hook seat 9. The adjacent right-angled sides of the upper handrail hook seat 8 are respectively provided with a plurality of first mounting holes 81, and the bottom surface of the lower handrail hook seat 9 is provided with a plurality of second mounting holes 91 at intervals. The upper handrail hook seat 8 and the lower handrail hook seat 9 can be fixed at the upper and lower ends of the same side of the installation position through the first mounting holes 81 and the second mounting holes 91, thereby facilitating the installation and fixing of the pull rod 3.

[0039] In one embodiment of this utility model, the upper seat 8 and the lower seat 9 of the handrail hook are respectively provided with a first groove and a second groove for inserting the two ends of the pull rod 3. The length of the first groove is less than the length of the right angle side of the upper seat 8 of the handrail hook, so that a notch is formed on the side of the first groove to facilitate the insertion of the pull rod 3. When the pull rod 3 is inserted, the bottom end of the pull rod 3 is inserted into the second groove, and the top end of the pull rod 3 can be easily inserted into the first groove from the notch, thus completing the limitation of the stretching length of the mesh fabric 2.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
