Implementation

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Example

[0018] like Figure 1-Figure 6 As shown, this embodiment discloses a fire hose support fixing frame with strong adaptability, including a base 1, a storage groove 11 is opened in the middle of the upper end of the base 1, and a telescopic support rod 2 is arranged inside the storage groove 11. The structure of the telescopic support rod 2 is similar to an enlarged version of the folding umbrella pole. This is a prior art, so it is not described in detail. The upper end of the telescopic support rod 2 extends to the outside of the storage groove 11 and is provided with a mounting plate 3. The rear part of the lower end of the mounting plate 3 is provided with two whet rods 31, and the whet rods 31 and the horizontal part of the control plate 75 are located in the same vertical plane; For details, please refer to Figure 2 — Figure 4, a movable groove 12 is provided on the left inner wall and the right inner wall of the storage groove 11, a sliding groove 2 13 is provided on the inner wall on the side away from each other of the two movable grooves 12, and a movable groove 2 14 is provided on the inner wall on the side away from each other of the two sliding grooves 2 13. The movable groove 2 14, the sliding groove 2 13 and the movable groove 1 12 are provided with a pressing mechanism 6 inside, a connecting groove 15 is provided on the inner wall on the rear side of the movable groove 12 and the storage groove 11, and an empty groove 17 is provided on the inner wall on the rear side of the two connecting grooves 15. The top wall of the empty groove 17 is provided with two mounting grooves, and an inclined groove 16 is provided on the side of the bottom wall of the empty groove 17 away from the storage groove 11 and the movable groove 1 12, and the movable plate 2 18 is provided inside the empty groove 17. The lower end of the movable plate 2 18 is provided with an inclined plate 19, and the inclined plate 19 is slidably connected with the movable plate 2 18, and the lower part of the inclined plate 19 passes through the inclined groove 16 and extends to the outside of the base 1; It can be seen that by pressing the movable plate 2 18, the inclined plate 19 is pressed by the inner wall of the inclined groove 16 to move downward and slide to the right, so that the inclined plate 19 can extend out of the base 1 in the inclined direction and then rest on the ground to offset part of the reverse impact force received by the fire hose during operation and maintain the stability of the device as much as possible; Specifically, a portion of the inclined plate 19 away from the movable plate 18 is a triangular structure for resisting the ground, which increases the pressure between the inclined plate 19 and the ground by reducing the contact surface, increases the resistance when the device moves, and keeps the device as stable as possible when the fire hose is working; For details, please refer to Figure 1 and Figure 3-Figure 5 The pressing mechanism 6 includes a moving plate 61 slidably connected to the moving groove 12, and a pressing plate 62 slidably connected to the moving plate 18 is provided at one end of the moving plate 61 close to the receiving groove 11. The pressing plate 62 is located in the receiving groove 11 and the connecting groove 15 when working, and is stored in the moving groove 12 and the connecting groove 15 when not working. An L-shaped moving rod 63 slidably connected to the sliding groove 13 and the moving groove 14 and a spring 64 wound around the outside of the horizontal part of the L-shaped moving rod 63 are provided in the middle of one end of the moving plate 61 close to the sliding groove 13, so that the pressing plate 62 can automatically enter the receiving groove 11 under the action of the spring 64, and a part of the L-shaped moving rod 63 away from the moving plate 61 extends to the outside of the base 1; It can be seen that when using the device, the telescopic support rod 2 and the mounting plate 3 are first raised to move the telescopic support rod 2 to the upper side of the pressing plate 62, so that the pressing plate 62 can enter the storage groove 11 by the elastic force of the L-shaped moving rod 63, and then the mounting plate 3 is loosened, so that the telescopic support rod 2 can use the gravity of the automatic and mounting plate 3 to press the pressing plate 62 to move downward, thereby driving the moving plate 18 to move downward together, forcing the inclined plate 19 to tilt out of the base 1 and rest on the ground; For details, please refer to Figure 4 and Figure 6 The rear end of the base 1 is provided with a retracting mechanism 7 for controlling the movement of the movable plate 2 18, the retracting mechanism 7 includes two fixed pulleys 1 74 respectively fixedly connected to the top walls of the two mounting grooves and two fixed pulleys 2 73 fixedly connected to the upper part of the rear end of the base 1, the upper left part and the upper right part of the movable plate 2 18 are both provided with movable pulleys 71, the bottoms of the two fixed pulleys 1 74 are both provided with pulling ropes 72, and the parts of the two pulling ropes 72 away from the pulling ropes 72 respectively bypass the movable pulley 71, the fixed pulley 1 74 and the fixed pulley 2 73 in turn and are jointly provided with a control plate 75 slidably connected to the rear end of the base 1; The pulley structure in the retracting mechanism 7 not only changes the pulling direction of the pulling rope 72 and facilitates the retraction of the inclined plate 19, but also has a certain labor-saving effect, so that it can save the physical strength of the firefighters and is convenient for the firefighters to use; It can be seen that when the control device needs to move or turn, the pulling rope 72 is pulled by stepping on the control plate 75. After the fixed pulley 73 and the fixed pulley 74 turn, the pulling rope 72 pulls the movable plate 18 and the inclined plate 19 upward by lifting the movable pulley 71, so that the inclined plate 19 can be quickly retracted into the inclined slot 16 and the empty slot 17 when needed. Furthermore, when the base 1 and the mounting plate 3 are in close contact with each other, the control plate 75 moves down to the bottom of the base 1. When the mounting plate 3 moves down, it squeezes the control plate 75 through the grinding rod 31 to move down, thereby pulling the movable plate 2 18 and the inclined plate 19 to move up, thereby facilitating the transportation of the shrunk device.

[0019] Therefore, the specific implementation of this embodiment is: First, the telescopic support rod 2 and the mounting plate 3 are raised, and then the telescopic support rod 2 is stretched to move the mounting plate 3 to a higher position. At the same time, the grinding rod 31 moves together with the mounting plate 3 to cancel the squeezing of the control plate 75. In this process, the movable plate 1 61 and the pressing plate 62 will move toward the receiving groove 11 under the action of the spring 64, so that the pressing plate 62 enters the receiving groove 11, and then the mounting plate 3 is released, so that the telescopic support rod 2 uses its own gravity and the mounting plate 3 to fall and squeeze the pressing plate 62, forcing the pressing plate 62 to drive the movable plate 2 18 to move downward, and then the inclined plate 19 is squeezed by the inner wall of the inclined groove 16 and extends from the base 1 in the inclined direction until the inclined plate 19 is against the ground, increasing the resistance of the device when moving, thereby limiting the device; When the device needs to move or turn, the pulling rope 72 is pulled by stepping on the control plate 75. After the fixed pulley 2 73 and the fixed pulley 1 74 turn, the pulling rope 72 pulls the movable pulley 71 to pull the movable plate 2 18 and the inclined plate 19 upward, so that the inclined plate 19 is quickly retracted into the inclined groove 16 and the empty groove 17, and the limit on the device is released. Example

[0020] This embodiment adds a limiting mechanism 4 and a fixing mechanism 5 on the basis of the first embodiment, so as to limit the position of the fire hose and make it easier for firefighters to use it. Figure 7-10 As shown, a fixing mechanism 5 is provided between the two sides of the two limiting mechanisms 4 that are close to each other. The fixing mechanism 5 includes a fixing ring 51. Two rotating plates 54 that are respectively slidably connected to the two arc-shaped slide grooves 457 are provided in the middle of the outer surface of the fixing ring 51. A handle 52 for facilitating the firefighter to control the direction of the water gun is provided on the upper part of the outer surface of the fixing ring 51. The handle 52 is provided to facilitate the firefighter to control the direction of the fire hose. Two symmetrically arranged screw rods 53 are provided on the upper part of the outer surface of the fixing ring 51. One end of the screw rod 53 close to the fixing ring 51 extends to the inner side of the fixing ring 51 and is provided with a positioning plate. It can be seen that after the fire hose is placed in the fixing ring 51, the screw 53 is rotated to allow the positioning plate to squeeze the fire hose to fix it, thereby preventing the fire hose from being separated during operation. For details, please refer to Figure 8 , two symmetrically arranged limiting mechanisms 4 are provided at the upper end of the mounting plate 3, and the limiting mechanism 4 includes a support plate 41 fixedly connected to the mounting plate 3, and a limiting groove is provided at the rear part of one end of the support plate 41 close to the fixing mechanism 5, and an opening groove 411 penetrating the rear end of the support plate 41 is provided at the upper and lower parts of the inner surface of the limiting groove, and a limiting mechanism is provided at the inner and outer sides of the limiting groove, and a rotating rod 453 is provided at the inner middle side of the limiting groove, and a limiting block 455 is provided at the outer front side of the rotating rod 453, and an arc-shaped long plate 45 is provided at one end of the rotating rod 453 close to the fixing mechanism 5, and an arc-shaped sliding groove 457 is provided at the middle part of one side of the arc-shaped long plate 45 close to the fixing mechanism 5; It can be seen that the rotation angle of the limit block 455 is limited by the limit mechanism, thereby limiting the up and down swing amplitude of the fire hose, so that even if the firefighter releases the fire hose due to fatigue, the fire hose that is spraying water will not accidentally injure the surrounding people; For details, please refer to Figure 7 , Fig. 9 and Fig.10 The left and right upper ends of the mounting plate 3 are both provided with a slide groove 32, and a plurality of positioning grooves are evenly provided in the middle of the bottom wall of the slide groove 32, and a plug rod 43 is provided inside the positioning groove, and a slide plate 42 slidably connected to the slide groove 32 is provided on the outer surface of the plug rod 43, and the upper end of the plug rod 43 extends to the upper side of the slide plate 42 and is provided with a disc 44; It can be seen that the insertion rod 43 is controlled to move up and down by moving the disc 44 to fix the slide plate 42, thereby preventing the slide plate 42 from passively retreating and affecting the limiting range of the limiting mechanism; Specifically, the limiting mechanism includes a fixed rod 424 fixedly connected to the middle side of the rear portion of the inner surface of the limiting groove, an arc-shaped short plate 425 is provided at one end of the fixed rod 424 close to the rotating rod 453, an arc-shaped sleeve 426 slidably connected to the limiting groove is provided at the upper and lower portions of the outer surface of the arc-shaped short plate 425, a push-pull plate 456 is provided on the outer surface of the arc-shaped sleeve 426, a portion of the push-pull plate 456 away from the arc-shaped sleeve 426 extends to the outside of the opening groove 411 and is rotatably connected to the slide plate 42; It can be seen that by moving the slide plate 42, the push-pull plate 456 is rotated to push the arc sleeve 426, and then the arc sleeve 426 moves in a circular trajectory under the restriction of the arc short plate 425, changing the distance between the two arc sleeves 426 and one end away from the push-pull plate 456, thereby limiting the rotation angle of the limit block 455 and the rotating rod 453; For details, please refer to Figure 8 , Fig. 9 and Fig.10 The rear end of the arc-shaped long plate 45 is provided with an arc-shaped telescopic rod 451, and the telescopic part of the arc-shaped telescopic rod 451 passes through the side wall of the arc-shaped slide groove 457 and extends into the arc-shaped slide groove 457 to limit the rotation angle of the rotating plate 54. The end of the fixed rod 424 away from the arc-shaped short plate 425 extends to the outside of the support plate 41 and is provided with a storage box 423. The upper part of the front end of the slide plate 42 is provided with an extrusion rod 421, and the front end of the extrusion rod 421 is provided with a pushing block 422 slidably connected to the storage box 423. The storage box 423 is close to the arc-shaped long plate 45. A hydraulic oil pipe 452 is provided between one end and the end of the arc-shaped telescopic rod 451 away from the arc-shaped long plate 45, which connects the storage box 423 and the arc-shaped telescopic rod 451. The hydraulic oil pipe 452 can withstand high pressure, is not easy to expand and deform, is low in price, and has a certain toughness. It can prevent the rotating plate 54 from squeezing the arc-shaped telescopic rod 451, causing the water flow in the arc-shaped telescopic rod 451 to flow back into the hydraulic oil pipe 452, affecting the normal operation of the arc-shaped telescopic rod 451. The storage box 423 and the hydraulic oil pipe 452 are filled with water. It can be seen that when the slide plate 42 moves to control the limit mechanism to limit the rotation angle of the limit block 455, it will also squeeze the water flow in the storage box 423 through the squeezing rod 421 and the pushing block 422, so that the water flow enters the arc-shaped telescopic rod 451 through the hydraulic oil pipe 452, forcing the arc-shaped telescopic rod 451 to extend to limit the rotation angle of the rotating plate 54; Therefore, the specific implementation of this embodiment is: After the fire hose is placed in the fixing ring 51, the screw 53 is rotated to fix the fire hose by squeezing the positioning plate, and then the slide plate 42 is moved according to the scope of the fire to be extinguished, so that the slide plate 42 pushes the water flow into the arc telescopic rod 451 through the squeezing rod 421 and the pushing block 422, forcing the arc telescopic rod 451 to extend to limit the rotating plate 54, and at the same time, the arc sleeve 426 slides on the arc short plate 425 by pushing the push-pull plate 456, changing the distance between the two arc sleeves 426 and one end away from the push-pull plate 456, and limiting the rotation angle of the limit block 455; In summary, by limiting the up and down flipping angle and left and right rotation angle of the fire hose gun to limit the working range of the fire hose gun, firefighters can carry out targeted firefighting under the action of this device, saving firefighters' physical strength and thus reducing firefighters' fatigue.
