[0040] As shown in the drawings, Figure 3 and Figure 5As shown, in some embodiments, the chute 2111 is arranged to extend away from the blanket body 1, and the chute 2111 has a through hole 21111 at an end thereof away from the blanket body 1, and the matching groove 2112 is connected to the end of the chute 2111 close to the blanket body 1. The length of the locking pin 212 in the extending direction of the chute 2111 is greater than the sum of the lengths of the chute 2111 and the matching groove 2112 in the direction, and at least part of the locking pin 212 is exposed outside the chute 2111 through the through hole 21111. In use, by holding the part of the locking pin 212 exposed outside the chute 2111, the locking pin 212 can be moved in the chute 2111, and the locking pin 212 can be inserted into the matching groove 2112 from the chute 2111 and inserted and fixed with the locking hole 231 on the plug block 23. Thus, after the plug block 23 is inserted into the matching groove 2112, the locking pin 212 is pressed to be inserted into the locking hole of the plug block 23, so as to fix the movable end 222 of the fixing belt 22 in the matching groove 2112. The connection between the movable end 222 of the fixing belt 22 and the lock seat 211 is more convenient and fast, and the convenience of use of the fireproof and explosion-proof blanket 100 is further improved.

[0041] As shown in Figure 3 and Figure 5 , specifically, the blanket body 1 is laid on the horizontal plane, the chute 2111 is arranged inside the lock seat 211 and extends in the vertical direction, the through hole 21111 is arranged on the top of the lock seat 211, and the locking pin 212 is movably arranged in the chute 2111 and part of the locking pin 212 is exposed from the through hole 21111 on the top of the lock seat 211. The matching groove 2112 is arranged at an end of the chute 2111 close to the blanket body 1, i.e. the matching groove 2112 is below the chute 2111, and the side wall of the lock seat 211 is provided with the insertion hole 21121 communicating with the matching groove 2112, and the plug block 23 can be inserted into the insertion hole 21121. After the plug block 23 is inserted into the matching groove 2112 through the insertion hole 21121, the locking pin 212 is pressed, the locking pin 212 is inserted into the matching groove 2112 from the chute 2111 and gradually inserted into the locking hole of the plug block 23, so as to fix the plug block 23 in the lock seat 211.

[0042] As shown in Figure 3 and Figure 5 , optionally, the insertion hole 21121 communicating with the matching groove 2112 is arranged on the side wall of each of the opposite sides of the lock seat 211, and the plug block 23 can be inserted into the matching groove 2112 through different insertion holes 21121. Therefore, the fixing belt 22 can be wound around the blanket body 1 in the clockwise or counterclockwise direction according to the situation, and the use is more convenient.

[0043] As shown in Figure 3As shown, in some embodiments, the locking pin 212 has a first end portion 2121, a sliding portion 2122 and a locking portion 2123 connected in sequence. The first end portion 2121 exposes the sliding groove 2111, and by holding the first end portion 2121, the sliding portion 2122 and the sliding groove 2111 can be relatively moved, so that the locking portion 2123 is extended into the matching groove 2112 and is inserted and fixed in the lock hole 231.

[0044] As shown in Figure 3 and Figure 4 shown, in some embodiments, the locking structure 21 further comprises a limiting rod 213 and a limiting sleeve 214, the limiting rod 213 is fixedly connected to the lock seat 211, the outer surface of the limiting rod 213 has a first threaded portion 2131, the limiting sleeve 214 is movably sleeved on the limiting rod 213 and the inner surface is provided with a second threaded portion, the first threaded portion 2131 is screwed with the second threaded portion, and the limiting sleeve 214 is movably sleeved on the limiting rod 213; the limiting sleeve 214 abuts against the first end portion 2121 of the locking pin 212 facing the through hole 21111. In use, the limiting sleeve 214 is fixed on the limiting rod 213 by screwing the limiting sleeve 214 with the limiting rod 213. After the locking pin 212 is inserted into the lock hole 231, the limiting sleeve 214 abuts against the first end portion 2121, and the limiting sleeve 214 limits the displacement of the first end portion 2121, thereby continuously limiting the locking pin 212 in the lock hole 231, maintaining the relative position between the locking block 23 and the lock seat 211, and further improving the stability of connection and fixation.

[0045] As shown in Figure 3 and Figure 4 shown, in one specific example, one end of the limiting rod 213 is fixed to one side of the lock seat 211 where the through hole 21111 is formed, and the other end of the limiting rod 213 extends along the extension direction parallel to the sliding groove 2111. The outer surface of the limiting rod 213 is provided with a first threaded portion 2131, and the limiting sleeve 214 is sleeved on the first threaded portion 2131 of the limiting rod 213 and the inner surface of the limiting sleeve 214 has a second threaded portion, and the first threaded portion 2131 is screwed with the second threaded portion. Turn the limiting sleeve 214, the limiting sleeve 214 approaches until abuts against the first end portion 2121 of the locking pin 212; continue to turn the limiting sleeve 214, the limiting sleeve 214 drives the locking portion 2123 of the locking pin 212 to extend into the matching groove 2112, until the locking portion 2123 is inserted and matched with the lock hole 231. The limiting sleeve 214 can continuously keep the locking pin 212 in the locking and fixing position with the lock hole 231, improving the stability of connection and fixation.

[0046] As shown in Figure 3 and Figure 4 shown, further, the outer surface of the limiting sleeve 214 is fixedly connected with a flange portion 2141, and the lower surface of the flange portion 2141 abuts against the first end portion 2121.

[0047] As shown in Figure 3 and Figure 4 In some embodiments, the locking structure 21 further comprises a restoring mechanism 215. The restoring force of the restoring mechanism 215 abuts the first end portion 2121 against the limiting sleeve 214. That is, the end portion of the locking pin 212 can continuously abut against the limiting sleeve 214 through the restoring mechanism 215. When the limiting sleeve 214 is rotated to lock, the thread fastening force between the limiting sleeve 214 and the limiting rod 213 is greater than or equal to the restoring force, so that the limiting sleeve 214 can continuously keep the locking pin 212 in the locking and fitting position of the locking hole 231, thereby improving the stability of the connection and fixation. When the limiting sleeve 214 is rotated in the opposite direction, the restoring force pushes the end portion of the locking pin 212 against the limiting sleeve 214, that is, the restoring force can drive the locking pin 212 to exit the fitting groove 2112. Therefore, the operator only needs to rotate the limiting sleeve 214 in the opposite direction, and the locking pin 212 can automatically exit the locking hole 231 without the operator's operation, thereby improving the convenience of use.

[0048] As shown in Figure 3 and Figure 4 In some embodiments, the first end portion 2121 has a first end face facing the lock seat 211 and a second end face away from the lock seat 211; the restoring mechanism 215 is an elastic member, one end of the elastic member is abutted against the lock seat 211, and the other end of the elastic member is abutted against the first end face; the limiting sleeve 214 abuts against the second end face; and the abutting force of the limiting sleeve 214 on the locking pin 212 is opposite to the elastic force of the elastic member. The elastic member is in a compressed state and has a restoring elongation tendency, the elastic member abuts against the first end face of the first end portion 2121 and has a tendency to drive the locking pin 212 to exit the fitting groove 2112, the limiting sleeve 214 abuts against the second end face, and the abutting force direction of the limiting sleeve 214 on the first end portion 2121 is opposite to the elastic force direction of the elastic member. Therefore, the operator only needs to rotate the limiting sleeve 214 in the opposite direction, and the locking pin 212 can automatically exit the locking hole 231 without the operator's operation, thereby improving the convenience of use.

[0049] As shown in Figure 3 and Figure 4As shown, in some embodiments, the end of the locking pin 212 facing the through hole 21111 is fixedly connected with a guide cylinder 216, and a guide rod 217 is fixedly connected to the lock seat 211; the extension direction of the guide rod 217 is parallel to the extension direction of the sliding groove 2111; the guide cylinder 216 is movably sleeved on the guide rod 217, one end of the guide cylinder 216 facing the lock seat 211 is an open end, and the end of the guide cylinder 216 connected with the locking pin 212 is a closed end; the distance between the open end and the closed end is L1, and the distance of the matching groove 2112 in the extension direction of the sliding groove 2111 is L2, L1≤L2. The cooperation between the guide cylinder 216 and the guide rod 217 limits the movement stroke of the locking pin 212, which can avoid the part of the locking pin 212 extending into the matching groove 2112 from being in contact with the groove wall of the matching groove 2112, thereby reducing the probability of damage and improving the stability and reliability of the locking.

[0050] As shown in Figure 1 and Figures 1-5 specifically, the first end face of the first end portion 2121 is fixedly connected with a guide cylinder 216, and the guide cylinder 216 is provided with a hollow cavity; one end of the hollow cavity close to the first end portion 2121 is a closed end, and one end of the hollow cavity close to the lock seat 211 is an open end. The lock seat 211 is provided with a guide rod 217, and the guide rod 217 can move in the guide cylinder 216; the distance between the open end and the closed end is L1, and the distance of the matching groove 2112 in the extension direction of the sliding groove 2111 is L2, L1≤L2. That is to say, the maximum movement stroke of the locking pin 212 is L1, which is smaller than the distance of the matching groove 2112 in the extension direction of the sliding groove 2111, so that the part of the locking pin 212 extending into the matching groove 2112 can be prevented from being in contact with the groove wall of the matching groove 2112.

[0051] As shown in Figures 1 to 5 in some embodiments, the lock hole 231 is a plurality of, each lock hole 231 can be locked and fixed with the locking pin 212, and the reliability of connection and fixation is improved.
