Technical Field
[0001] The utility model relates to the technical field of fire blankets, in particular to an X-shaped fire blanket throwing rod. Background Art
[0002] A fire blanket, also known as a fireproof blanket, fireproof quilt, fireproof blanket, fire blanket, flame retardant blanket, or escape blanket, is a fabric woven from materials such as fiberglass through special treatment. It can isolate heat sources and flames and is an ideal and effective outer protective layer for people and objects that need to stay away from heat sources. It is very easy to wrap objects with uneven surfaces. It is a simple fire extinguishing tool for enterprises, stores, ships, cars, and civilian buildings. As more and more products such as electric bicycles and electric cars are getting closer to people's production and life, the corresponding fire hazards are increasing, and new products such as fire blankets (fire extinguishing water blankets) specifically for fires of new energy technology products are constantly increasing.
[0003] When using a fire blanket to extinguish a fire, it is usually necessary for the user to hold the fire blanket by hand and cover it on the fire source. However, when the fire source has a flashover, splashes, or a large flame, it is easy to injure the operator. In addition, it is difficult to cover the fire blanket on the fire source in special cases where the fire source point is at a high or far position. For new fire blankets, due to the particularity of the fire sources they are designed for, they are often large in volume and weight, making it difficult to throw them. Therefore, providing a throwing rod that facilitates covering the fire blanket on the fire source is a technical problem that needs to be urgently solved by those skilled in the art.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model.
[0025] Please refer to Figure 1-6 , the present utility model provides a technical solution: an X-type fire blanket throwing rod, including a main rod 1, a first support rod 2, a second support rod 3, two pairs of blanket connection assemblies 4, a first pull rope 5, a second pull rope 6, and a third pull rope 7;
[0026] The first support rod 2 is hinged at the center of the second support rod 3. After being combined, it forms a straight line shape, and after being opened, it forms an X shape. One end of the main rod 1 is hinged to one end of the first support rod 2. After combining the first support rod 2 and the second support rod 3, they can be folded with the main rod 1, which is convenient for storage and transportation. One pair of blanket connection components 4 are fixedly arranged below both ends of the first support rod 2, and the other pair of blanket connection components 4 are fixedly arranged below both ends of the second support rod 3, so as to connect the four corners of the fire extinguishing blanket and unfold the fire extinguishing blanket.
[0027] The blanket connection component 4 includes a fixed seat 4-1 and a connection ring 4-2. A notch 4-3 is formed in the fixed seat 4-1. The upper part of the connection ring 4-2 can be placed in the notch 4-3, and the lower part of the connection ring 4-2 can be connected to the four corners of the fire extinguishing blanket. A bolt 4-4 is slidably arranged in the fixed seat 4-1. One end of the bolt 4-4 extends into the notch 4-3 and can be inserted into the connection ring 4-2. A spring 4-5 is also arranged in the fixed seat 4-1. The spring 4-5 can push the bolt 4-4 to move towards the notch 4-3 side, and the bolt 4-4 can be in a normally closed state through the spring 4-5.
[0028] Pulling the first pull rope 5 can adjust the angle between the first support rod 2 and the main rod 1. Pulling the second pull rope 6 can convert the second support rod 3 from an overlapping straight line state with the first support rod 2 to an X-shaped cross state. Pulling the third pull rope 7 can move the bolt 4-4 out of the notch 4-3, so that the connection ring 4-2 can be separated from the fixed seat 4-1.
[0029] As an embodiment of the present invention, a plurality of hooks 1-1 with different positions are fixedly arranged on the main rod 1. A plurality of guide wheels 1-2 are rotatably arranged on one side of the main rod 1 close to the first support rod 2 to realize the guiding of the pull ropes. The first pull rope 5, the second pull rope 6, and the third pull rope 7 respectively bypass the guide wheels 1-2 and are arranged on the outer surfaces of the first support rod 2 and the main rod 1 through a plurality of guide rings 8. The pull ropes can be limited by the guide rings 8. One end of each of the first pull rope 5, the second pull rope 6, and the third pull rope 7 is fixedly connected with a hanging ring, and the hanging ring can be hung on the hook 1-1.
[0030] As an embodiment of the present invention, a fixed ring 2-4 is fixedly arranged above the first support rod 2. The other end of the first pull rope 5 is fixedly connected to the fixed ring 2-4. After hanging the hanging ring at one end of the first pull rope 5 on the hook 1-1, one end of the first pull rope 5 can be fixed, realizing the fixation of the angle between the main rod 1 and the first support rod 2. By hanging it on the hooks 1-1 at different positions, the angle between the main rod 1 and the first support rod 2 can be changed.
[0031] As an embodiment of the present utility model, a rotating shaft 2-1 is rotatably arranged on the first support rod 2. A first gear 2-2 is fixedly arranged at the lower end of the rotating shaft 2-1. A second gear 3-1 meshing with the first gear 2-2 is fixedly arranged on the second support rod 3. A rope reel 2-3 is fixedly arranged at the upper end of the rotating shaft 2-1. The other end of the second pulling rope 6 is wound around the rope reel 2-3. Pulling the second pulling rope 6 can drive the rotating shaft 2-1 to rotate through the rope reel 2-3. A limiting member (not shown in the figure) is arranged between the second support rod 3 and the first support rod 2 to enable it to rotate within the range of 0 degrees to 90 degrees.
[0032] As an embodiment of the present utility model, the other end of the bolt 4-4 is fixedly connected with a fourth pulling rope 9. The fourth pulling ropes 9 are all connected with the third pulling rope 7. Pulling the third pulling rope 7 can drive the fourth pulling rope 9, so that the bolt 4-4 is moved out of the notch 4-3. By pulling the third pulling rope 7, the fourth pulling ropes 9 connected to each bolt 4-4 can be driven simultaneously, so as to realize that pulling the third pulling rope 7 can make the four bolts 4-4 be pulled out of the notch 4-3 at the same time.
[0033] As an embodiment of the present utility model, a counterweight 4-6 is fixedly arranged on the connecting ring 4-2. The weight of the connecting ring 4-2 can be increased through the counterweight 4-6, so as to increase the weight at the four corners of the fire extinguishing blanket and realize the rapid descent of the fire extinguishing blanket.
[0034] As an embodiment of the present utility model, the main rod 1, the first support rod 2, and the second support rod 3 are all made of hollow square tubes, which reduces the overall weight of the device.
[0035] The working principle and usage process of the present utility model: When in use, pull the first pulling rope 5 to open the first support rod 2. The angle between the first support rod 2 and the main rod 1 can be changed by hanging the hanging ring at one end of the first pulling rope 5 on the hooks 1-1 at different positions. Fix the four corners of the fire extinguishing blanket to the connecting ring 4-2. Insert the connecting ring 4-2 into the notch 4-3 of the fixing seat 4-1 and fix it with the bolt 4-4. Pulling the second pulling rope 6 can make the second support rod 3 rotate, so that the end of the throwing rod is in an X shape to unfold the fire extinguishing blanket. Hold the main rod 1 and move the fire extinguishing blanket above the fire source. Pulling the third pulling rope 7 can make the bolts 4-4 in the four blanket connecting components 4 be pulled out of the notch 4-3. At this time, the fire extinguishing blanket together with the connecting ring 4-2 with the counterweight 4-6 at the four corners falls freely to cover the fire source.
[0036] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
