DETAILED DESCRIPTION

[0024] The utility model will be further described below in combination with the drawings and embodiments.

[0025] Referring to Figures 1-6 The positioning assembly of the roller shutter door: including roller shutter door 1, sliding beam plate 2 is fixedly installed at the lower end of roller shutter door 1, and positioning assembly 6 is installed on the inner side of sliding beam plate 2; positioning assembly 6 includes two sliding blocks 61, installation sliding groove 5 is formed in the inner side of sliding beam plate 2, the two sliding blocks 61 are slidably installed at the two end ports of installation sliding groove 5 respectively, pad plate 62 is installed on the outer side end of sliding block 61, inner threaded cylinder 612 is fixedly installed on the inner side of sliding beam plate 2, threaded column 610 is screw-connectedly installed on the inner side of inner threaded cylinder 612, disc 68 is arranged on the inner side of threaded column 610, cable 65 is fixedly connected between disc 68 and the inner side end of sliding block 61, return spring 66 is fixedly installed between the inner side end of sliding block 61 and the inner wall of installation sliding groove 5, rotating clamp 69 is fixedly installed on disc 68, clamping groove that is matched with rotating clamp 69 is formed in the inner side of threaded column 610, and rotating clamp 69 is rotatably clamped in the inner side of clamping groove.

[0026] Through the above-mentioned mode, disc 68 is rotatably connected with threaded column 610 through rotating clamp 69, and then when threaded column 610 rotates, disc 68 cannot be driven to rotate by threaded column 610, so that threaded column 610 can only drive disc 68 to move in the direction of inner threaded cylinder 612, so as to pull cable 65.

[0027] In the mode, guide roller 67 is rotatably installed on the inner side of installation sliding groove 5, and cable 65 is wound through guide roller 67.

[0028] Through the above-mentioned mode, the setting of guide roller 67 provides the guiding effect of turning of cable 65, prevents cable 65 from scratching the inner wall of installation sliding groove 5, reduces the abrasion and consumption of cable 65, and further improves the service life of cable 65.

[0029] In the mode, rotating handle 611 is fixedly installed on the outer side of threaded column 610.

[0030] Through the above-mentioned mode, the setting of rotating handle 611 facilitates the rotation of threaded column 610 by holding rotating handle 611.

[0031] In the present embodiment, the installation sliding groove 5 penetrates through the inside of the sliding beam plate 2, and the cable 65 is located inside the installation sliding groove 5.

[0032] In the present embodiment, the cushion plate 62 is made of rubber, and a concave hole 63 is formed on the outside of the cushion plate 62, and the installation screw 64 is screwed and installed inside the concave hole 63.

[0033] Through the above-mentioned arrangement, the cushion plate 62 is made of rubber, and the surface friction coefficient of the cushion plate 62 is relatively high, so that when the cushion plate 62 abuts against the roller shutter door track, sufficient friction force can be provided to stably clamp the two ends of the sliding beam plate 2 on the track, thereby realizing the positioning of the sliding beam plate 2.

[0034] In the present embodiment, the cable 65 is a stainless steel wire rope.

[0035] Through the above-mentioned arrangement, the cable 65 is a stainless steel wire rope, which can improve the tensile strength of the cable 65 and also strengthen the durability.

[0036] In the present embodiment, the outer handle 3 and the inner handle 4 are respectively fixedly installed on the two sides of the sliding beam plate 2.

[0037] Through the above-mentioned arrangement, the arrangement of the outer handle 3 and the inner handle 4 facilitates the opening or closing of the roller shutter door 1 from the inside and outside.

[0038] The working principle of the positioning assembly of the roller shutter door is as follows:

[0039] In use, the roller shutter door 1 is pulled down through the sliding beam plate 2, and when it is pulled down to a partially open position, the threaded column 610 can be driven to rotate by hand holding the rotating handle 611, the threaded column 610 is screwed and transmitted with the internal thread cylinder 612, the threaded column 610 slides to the inside end of the internal thread cylinder 612, and then drives the disc 68 to slide to the inside of the installation sliding groove 5, which is equivalent to the process of paying out the line, and under the action of the rebound force of the reset spring 66, the cable 65 is pulled to the two side ports of the installation sliding groove 5, so that the cable 65 always maintains a straight state, at the same time, the sliding block 61 located at the outside end of the reset spring 66 synchronously slides to the port of the installation sliding groove 5, so that the cushion plate 62 installed on the outside surface of the sliding block 61 abuts against the track on the two sides of the roller shutter door 1, and then the two ends of the sliding beam plate 2 are stably clamped inside the track, thereby realizing the stable positioning of the partially open or closed roller shutter door 1, and when the positioning effect needs to be cancelled, the threaded column 610 can be reversely rotated.

[0040] The above-mentioned is only an embodiment of the present utility model, and does not limit the patent range of the present utility model, and any equivalent structure or equivalent process conversion or direct or indirect application in other related technical fields by using the content of the present utility model specification and drawings is also included in the patent protection range of the present utility model.
