DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 5 The utility model provides a protective fence gap chain installation structure, including a guardrail 1 and a guardrail 2 3. A plurality of hanging rings 6 are welded on one side of the guardrail 1, and a protective chain 2 is hung in the hanging ring 6. A plurality of mounting frames 13 corresponding to the hanging rings 6 are fixed on one side of the guardrail 2 3 by bolts. A hanging rod 2 9 for hanging the protective chain 2 is welded on the top of the mounting frame 13. A mounting seat 8 is fixed on one side of the guardrail 2 3 by bolts. A rotating rod 7 is rotatably connected in the mounting seat 8. A plurality of blocking components for limiting the protective chain 2 are arranged on one side of the rotating rod 7. The blocking component is a claw 12, which is welded on one side of the rotating rod 7. A blocking groove 11 is opened on one side of the claw 12, and the blocking groove 11 is inserted into the outer side of the hanging rod 2 9 and blocks the protective chain 2. Each protective chain 2 is hung on the hanging rod 2 9 respectively, and then turned over. The rotating rod 7 is rotated so that the claw 12 set on the rotating rod 7 blocks the protection chain 2 through the blocking groove 11, and the protection chain 2 is limited on the hanging rod 2 9. At the same time, the rotating rod 7 passes through the locking ring 17 through the locking hole 18 and is locked and fixed by the padlock, thereby completing the rapid fixation of multiple protection chains 2. It is simple and convenient to use, and saves resources. The top of the guardrail 2 3 is provided with a locking component for fixing the position of the rotating rod 7. The locking component is a locking hole 18. The locking hole 18 is opened at the end of the rotating rod 7. A locking ring 17 is welded on one side of the guardrail 2 3, and the locking ring 17 passes through the locking hole 18. Both sides of the multiple blocking grooves 11 are provided with chamfered angles 10, which makes it easy for the hanging rod 2 9 to be stuck in the blocking groove 11. The bottoms of the multiple claws 12 are welded with connecting angle plates 16, and the connecting angle plates 16 are fixed to the guardrail 2 3, thereby improving the strength of the claws 12.

[0025] In order to facilitate the staff to padlock it, an iron sleeve 14 is fixed to one side of the guardrail 2 3 in the utility model by bolts, and the outer surface of the iron sleeve 14 is coated with protective paint. An installation groove is opened on one side of the rotating rod 7, and a magnetic plate 15 that is magnetically attracted to the iron sleeve 14 is fixed in the installation groove by bolts. The iron sleeve 14 is magnetically attracted by the magnetic plate 15, so that the rotating rod 7 is magnetically fixed when it is rotated to fit with the guardrail 2 3, thereby facilitating subsequent operations.

[0026] In order to place the protective chains 2 in an orderly manner when they are opened, a plurality of mounting frames 5 corresponding to the hanging rings 6 are fixed to one side of the guardrail 1 in the utility model by bolts, and a hanging rod 4 is welded to the top of the mounting frame 5. By arranging a plurality of hanging rods 4 on one side of the guardrail 1, it is convenient to hang the plurality of protective chains 2 on the corresponding hanging rods 4 respectively when the protective chains 2 are opened, thereby preventing the protective chains 2 from being scattered on the ground and entangled with each other, thereby affecting the subsequent installation.

[0027] The utility model is divided into the following steps when used:

[0028] S1: When opening, multiple protection chains 2 are hung on corresponding hanging rods 4 to prevent the protection chains 2 from being scattered on the ground and entangled with each other;

[0029] S2: During installation, each protective chain 2 is hung on the second hanging rod 9, and then the rotating rod 7 is turned over, so that the claw 12 provided on the rotating rod 7 blocks the protective chain 2 through the blocking groove 11, and the protective chain 2 is limited on the second hanging rod 9;

[0030] S3: At this time, the rotating rod 7 is magnetically fixed when it rotates to fit with the guardrail 2 3, so that it is convenient for the staff to padlock it;

[0031] S4: At the same time, the rotating rod 7 passes through the locking ring 17 through the locking hole 18 and is locked and fixed by the padlock, thereby completing the rapid fixation of the multiple protection chains 2.

[0032] Finally, a few points should be explained: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
