DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0018] The present application provides a fire-fighting and rescue window sill lifting bracket, which is mainly used to solve the problem that the existing fire-fighting lifting bracket needs to be extended when in use, so that its length exceeds the window sill to complete the installation. After use, it occupies a large area and is not convenient to store, which brings inconvenience to the user. The following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0019] like Figure 1-4As shown, a fire fighting and rescue window sill lifting bracket comprises a support column 1, an adjusting rod 2 is arranged in the support column 1, a slide groove 3 is constructed at one end of the adjusting rod 2, an L-shaped rod 4 is arranged in the slide groove 3, the L-shaped rod 4 can slide along the length of the slide groove 3 or be removed from the slide groove 3, two groups of extension rods 5 are also arranged at one end of the adjusting rod 2, a sliding groove 6 is opened in the support column 1, the adjusting rod 2 can slide along the length of the sliding groove 6 or be fixed at a certain position in the sliding groove 6, a sliding block 7 is installed in the sliding groove 6, the sliding block 7 is slidably connected to the sliding groove 6, a limiting rod 8 is arranged in the adjusting rod 2, the length of the limiting rod 8 passes through the adjusting rod 2 and the support column 1 at both ends, a plurality of limiting grooves 13 are opened on the corresponding limiting rods 8 on both sides of the support column 1, the limiting rods 8 can be inserted in the limiting grooves 13, the adjusting rod 2 The slider 7 can slide along the length of the sliding groove 6, and the adjusting rod 2 can be fixed in a certain position of the sliding groove 6 by inserting the limit rod 8 in the limit groove 13. The ends of the two groups of extension rods 5 close to each other are provided with threads, and the close ends of the two groups of extension rods 5 are threadedly connected to the adjusting rod 2. The ends of the two groups of extension rods 5 away from each other are slidably installed with support rods 9, and also include an adjustment component 10. The adjustment component 10 includes a limiting column 101, a limiting groove 102, and a spring 103. The limiting column 101 is slidably installed in the support rod 9. One end of the spring 103 is connected to the inner wall of the adjusting rod 2, and the other end is fixedly connected to the bottom of the limiting column 101. There are multiple groups of limiting grooves 102 and they are all opened on the surface of the extension rod 5. The limiting column 101 can be inserted in the limiting groove 102. The ends of the rods 9 that are away from each other are fixedly installed with support plates 11, and one side of the support plates 11 is fixedly installed with anti-slip pads 12. In some embodiments, before use, the support column 1 can be fixed to the ground by screws. After the adjusting rod 2 is adjusted to a suitable height, the height of the adjusting rod 2 is fixed by passing the limit rod 8 through the support column 1 and the two ends of the limit groove 13. At the same time, the extension rod 5 and the adjusting rod 2 are threadedly connected, and then the limit column 101 is pressed down to retract it into the support rod 9. At this time, the support rod 9 can slide freely in the extension rod 5. When it is adjusted to a suitable length, the limit column 101 is released. Under the action of the elastic force of the spring 103, the limit column 101 will be bounced up until it is stuck in the limit groove 102, thereby completing the adjustment of the length of the support rod 9 and making its length larger. The L-shaped rod 4 can be slid into the slide groove 3 to complete the disassembly of the L-shaped rod 4, and finally the threaded connection between the extension rod 5 and the adjusting rod 2 can be contacted to complete the disassembly of the extension rod 5, which solves the problem that the existing fire-fighting lifting bracket needs to be extended to make its length exceed the windowsill when in use, and the installation can be completed. After use, it occupies a large area and is not convenient to store, which brings inconvenience to the user.
