[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 The utility model comprises: an acid- and alkali-resistant protective clothing main body 1, a waist belt 3 wrapped around the waist of the entire acid- and alkali-resistant protective clothing main body 1, and the entire acid- and alkali-resistant protective clothing main body 1 is reinforced by the waist belt 3, and a buckle is arranged on the upper part of the waist belt 3, so that the buckle is clamped with the connecting belt 4, and a protective shoulder pad 2 is fixed on the top of the connecting belt 4, two sets of protective shoulder pads 2 can be placed on the shoulders, and a functional warehouse 5 is fixed at the end of the protective shoulder pad 2, and the surface of the functional warehouse 5 is closely attached to the upper area of ​​the back, and the functional warehouse 5 and the acid- and alkali-resistant protective clothing main body 1 are fixed in a fixed manner, which does not affect the normal installation of the oxygen cylinder, and the functional warehouse 5 can be in a relatively stable state on the back through the traction of the protective shoulder pad 2 and the waist belt 3.

[0029] The winding roller 6 is arranged in the cavity of the functional compartment 5, and a safety pull rope 7 is wound on the surface of the winding roller 6, wherein one end of the safety pull rope 7 is fixed to the winding roller 6, and the other end passes outward from the surface of the functional compartment 5, and a larger nodule is provided at the passed-out end. When it is needed, the nodule is pulled outward to rotate the winding roller 6, so that the safety pull rope 7 can be pulled out from the functional compartment 5. After the safety pull rope 7 is pulled out, the distance is long enough, so that the rescue personnel do not need to bend down to drag it, thereby reducing the difficulty of dragging and improving the rescue efficiency.

[0030] The limiting plug hole 12 is provided on the side wall of the winding roller 6, and the limiting plug 10 is inserted into the groove of the limiting plug hole 12, and a movable vertical rod 9 is fixed on the side wall of the limiting plug 10. When the winding position of the safety pull rope 7 needs to be fixed, the limiting plug 10 is brought close to the limiting plug hole 12, and the limiting plug 10 is finally inserted into the hole of the limiting plug hole 12. Since the limiting plug 10 can only move radially but not rotate, the winding roller 6 cannot continue to rotate, thereby limiting the extension length of the safety pull rope 7. A supporting rod 8 is fixed in the cavity of the functional compartment 5, wherein the top of the movable vertical rod 9 is slidably sleeved outside the supporting rod 8, and a supporting cylinder 11 is fixed at one end of the supporting rod 8, and a circular hole is provided at the side end of the winding roller 6, so that the front end of the supporting cylinder 11 can be extended into the circular hole, and the winding roller 6 is supported by the supporting cylinder 11 and the circular hole;

[0031] The clamping mechanism is arranged below the winding roller 6, and the clamping mechanism includes a moving upright rod 9, an adjusting support rod 15, a main moving block 16 and a spring portion 17. The moving upright rod 9 is slidably sleeved on the outside of the supporting rod 8, one end of the adjusting support rod 15 is connected to the bottom of the moving upright rod 9, the main moving block 16 is connected to the bottom end of the adjusting support rod 15, the spring portion 17 is installed at the bottom of the main moving block 16, the surface of the adjusting support rod 15 fits the limiting column block 18, and the two ends of the adjusting support rod 15 are rotatably connected to the moving upright rod 9 and the main moving block 16 respectively. Under the elastic drive of the spring portion 17, the main moving block 16 will move downward, so that the two groups of adjusting support rods 15 will produce rotational displacement, so that the two groups of moving upright rods 9 will move along the supporting rod. 8 slides outside, and finally the limiting plug-in 10 is inserted into the hole of the limiting socket 12 to fix the winding roller 6. When the safety pull rope 7 needs to be pulled out, it is only necessary to lift the main moving block 16 upward to disengage the limiting plug-in 10 from the limiting socket 12. In order to facilitate the lifting action of the main moving block 16, a lifting cross bar 20 is fixed on the surface of the main moving block 16, and a sliding groove is provided on the surface of the functional bin 5 to allow the lifting cross bar 20 to move longitudinally, which can be achieved by lifting the lifting cross bar 20 upward outside the functional bin 5. The two ends of the limiting column block 18 are fixed to the inner wall of the functional bin 5. The limiting column block 18 can be used to support the rotation of the adjusting support rod 15, and the limiting column block 18 is not fixed to the adjusting support rod 15.

[0032] The outer wall of the winding roller 6 is provided with an outer tooth portion 13, and an adjustment tooth cylinder 14 is provided on one side of the functional chamber 5, and the outer tooth portion 13 is meshed with the adjustment tooth cylinder 14. The functional chamber 5 is provided with an opening for the adjustment tooth cylinder 14 to pass through, and a socket is provided at the end of the adjustment tooth cylinder 14. In subsequent use, the lifting cross bar 20 can be lifted upward, and a tool can be inserted into the socket, and then the socket can be rotated to rotate the adjustment tooth cylinder 14, so that the adjustment tooth cylinder 14 drives the outer tooth portion 13 and then the winding roller 6 to rotate, so that the pulled safety rope 7 can be recovered and wound outside the winding roller 6.
