[0033] See Figures 1 to 5 One embodiment of this utility model discloses a fire hose recoil simulation device, used to mimic a fire hose and effectively simulate the recoil force of a fire hose during use. The fire hose recoil simulation device includes a base 1, a recoil simulation component 2, a fire hose model 3, and a rotating structure 4. The fire hose model 3 is fixedly connected to the recoil simulation component 2, and the recoil simulation component 2 is connected to the base 1 via the rotating structure 4. The recoil simulation component 2 simulates the recoil force of a real fire hose, and the fire hose model 3 simulates a real fire hose. The base 1 and the recoil simulation component 2 are rotatably connected via the rotating structure 4 to simulate the swing direction of a real fire hose and to accommodate the user's grip on the fire hose model 3. The fire hose model 3 is prior art and will not be described in detail here. The key aspect of this utility model lies in the recoil simulation component 2.

[0034] Specifically, such as Figure 1As shown, the recoil simulation component 2 includes a housing 21, a power component 22, a first moving block 23, a second moving block 24, a first elastic element 25, and a locking component 26. The power component 22 is mounted on the housing 21 and connected to the first moving block 23 to drive the first moving block 23 to move. The second moving block 24 is connected to the first elastic element 25. The locking component 26 is connected and cooperates with the first moving block 23 and the second moving block 24 to lock the relative positions of the first moving block 23 and the second moving block 24. The fire hose model 3 is fixedly connected to the second moving block 24. The base 1 is rotatably connected to the housing 21 through a rotating structure 4. The power component 22 is used to drive the first moving block 23 to move, the first elastic element 25 provides elastic force to the first moving block 23 and the second moving block 24, and the locking component 26 is used to lock the relative positions of the first moving block 23 and the second moving block 24 during relative movement, preventing the second moving block 24 from moving rapidly under the action of the elastic force of the first elastic element 25. The housing 21 is open, and the second movable block 24 can extend partially out of the housing 21 to connect with the fire hose model 3, or the fire hose model 3 can extend into the housing 21 to connect with the second movable block 24. The locking assembly 26 can also extend partially out of the housing 21 for operation by personnel, or personnel can reach into the housing 21 to operate the locking assembly 26.

[0035] In some embodiments, such as Figures 1 to 3 As shown, the power assembly 22 includes a power component 221, a transmission component 222, and several guide components 223. The power component 221 is mounted on the housing 21 and connected to the transmission component 222, which is connected to the first moving block 23. Each guide component 223 is parallel to the moving direction of the transmission component 222 and is fixedly connected to the housing 21. The first moving block 23 and / or the second moving block 24 are slidably connected to the guide component 223. The power component 221 provides power for the movement of the first moving block 23, the transmission component 222 transmits the power from the power component 221 to the first moving block 23, and the guide component 223 guides the moving direction of the first moving block 23 and / or the second moving block 24. Specifically, the first moving block 23 is slidably connected to the guide component 223 to guide the first moving block 23. The second moving block 24 is slidably connected to the guide component 223 to guide the second moving block 24. The first moving block 23 can be connected to the guide component 223 independently. Alternatively, the first moving block 23 and the second moving block 24 can be connected to the guide member 223 at the same time. The first moving block 23 and the second moving block 24 can be connected to the same guide member 223, or they can be connected to different guide members 223 respectively.

[0036] In some embodiments, the power component 221 is a motor, and the output end of the motor is fixedly connected to the transmission component 222. The transmission component 222 is a screw and is screwed to the first moving block 23. The motor is mounted on the housing 21, one end of the screw is connected to the output end of the motor, and the other end of the screw is rotatably connected to the housing. The rotation of the motor can drive the screw to rotate. Due to the screwed connection between the screw and the first moving block 23, the rotation of the screw can be converted into the axial movement of the first moving block 23, which in turn drives the second moving block 24, or compresses or stretches the first elastic element 25. Each guide component 223 is located on the outside of the transmission component 222, such as the upper side, lower side, left side, or right side. The guide component 223 is parallel to the screw and extends along the axial direction of the screw, and both ends of the guide component 223 are fixedly connected to the housing 21. The guide component 223 can be a guide rail, a guide groove, or a guide rod, etc. Figure 1 As shown, the orientation of this utility model is defined as follows: the front is the left side, the rear is the right side, the fire hose model 3 is located on the upper side, the base 1 is located on the lower side, the right side is the rear side, and the left side is the front side.

[0037] In some embodiments, the first elastic element 25 and the second movable block 24 are slidably sleeved on the transmission member 222, with a gap between them. This limits the deformation of the first elastic element 25, ensuring that it can only deform along the axial direction of the transmission member 222, thus reducing radial deformation of the transmission member 222. The second movable block 24 is sleeved on the transmission member 222, facilitating connection of the first elastic element 25. Preferably, the first elastic element 25 is a spring.

[0038] In use, the motor drives the screw to rotate, thereby moving the first moving block 23 along the direction of the guide member 223. The first moving block 23, through the first elastic member 25, causes the fire hose model 3 mounted on the second moving block 24 to move towards the user, that is, to move backward. The user holds the handle of the fire hose model 3 and can push the fire hose model 3 forward through the first elastic member 25 to counteract the force of the fire hose model 3 moving backward, thus allowing the user to feel the recoil of a real fire hose.

[0039] In some embodiments, such as Figure 2 and Figure 3As shown, the locking assembly 26 includes a telescopic assembly 261 and a sleeve 262. The telescopic assembly 261 is connected to the first movable block 23. The sleeve 262 is slidably fitted onto at least one guide member 223 and fixedly connected to the second movable block 24. The first movable block 23 is slidably fitted onto the sleeve 262. The sleeve 262 is provided with several slots 263. The protruding end of the telescopic assembly 261 cooperates with the slots 263 to lock the sleeve 262, the second movable block 24, and the fire hose model 3. Specifically, the second movable block 24 is fixed to the sleeve 262. When the second movable block 24 moves forward, the sleeve 262 moves accordingly, compressing the first elastic member 25. When the protruding end of the telescopic assembly 261 engages with the slots 263, the positions of the sleeve 262, the second movable block 24, and the fire hose model 3 are locked, while the first elastic member 25 is fixed to prevent it from moving under the elastic force, thus preventing the second movable block 24 from moving.

[0040] In some embodiments, such as Figure 4 and Figure 5 As shown, the telescopic assembly 261 includes a mounting block 2611, a mounting rod 2612, an externally threaded tube 2613, an internally threaded cap 2614, a locking block 2615, and a second elastic element 2616. The mounting block 2611 is fixedly connected to the first moving block 23, and the mounting block 2611 has a through hole facing the sleeve 262. The externally threaded tube 2613 is fixedly connected to the mounting block 2611, and the mounting rod 2612 is movably disposed within the externally threaded tube 2613 and the through hole. The internally threaded cap 2614 is screwed to the externally threaded tube 2613 and fixedly connected to the mounting rod 2612. The locking block 2615 is telescopically disposed on the mounting rod 2612 through the second elastic element 2616, and the protruding end of the locking block 2615 extends out of the through hole and engages with the locking groove 263. Rotating the internal thread cap 2614 moves the mounting rod 2612, causing the locking block 2615 to disengage from the slot 263, thus releasing the restriction on the second moving block 24, the sleeve 262, and the fire hose model 3. The mounting rod 2612 has a mounting hole for mounting the second elastic element 2616 and the locking block 2615. A limiting cover 2617 is provided between the mounting rod 2612 and the mounting block 2611. The locking block 2615 has a variable diameter structure, partially penetrating the limiting cover 2617 and extending towards the sleeve 262. The limiting cover 2617 prevents the second limiting element 264 from popping out and the locking block 2615 from completely disengaging. Preferably, the rear end of the locking block 2615 is inclined, and the front end of the slot 263 is also inclined.

[0041] Specifically, the mounting block 2611 can be part of the first movable block 23, with a through hole located on the side wall of the first movable block 23. The length of the mounting rod 2612 that can enter the through hole and the length of the locking block 2615 that can extend out of the mounting rod 2612 are greater than the length of the through hole. Understandably, in some other embodiments, the mounting block 2611 can be an independent structure, with the first movable block 23 additionally having a through hole penetrating the side wall. The mounting block 2611 can be located on the left side of the first movable block 23 and fixedly connected to the edge of the through hole. The mounting rod 2612 can be screwed into the through hole or freely pass through it, and the length of the mounting rod 2612 that can enter the through hole and the length of the locking block 2615 that can extend out of the mounting rod 2612 are greater than the length of the through hole.

[0042] In some embodiments, the locking assembly 26 further includes a limiting member 264, which is fixedly connected to the end of the sleeve 262 away from the second moving block 24. The limiting member 264 is used for resetting. For example, the limiting member 264 is located at the end of the sleeve away from the second moving block 24. The limiting member 264 is a limiting ring, which is slidably sleeved on the guide member 223 and fixedly connected to the sleeve. When the motor drives the screw to reverse, the first moving block 23 resets. The first moving block 23, in conjunction with the sleeve 262 and the limiting ring, drives the second moving block 24 and the fire hose model 3 to reset.

[0043] In some embodiments, such as Figure 3 As shown, the guide member 223 can be a guide rod. There are two guide members 223, each located on opposite sides of the transmission member 222. For example, the left and right sides, upper and lower sides of the transmission member 222. A sleeve 262 is slidably fitted onto at least one guide member 223, and a first moving block 23 and a second moving block 24 are slidably fitted onto the other guide member 223. For example, the sleeve 262 may be fitted onto one guide member 223, or both guide members 223, and the number of sleeves 262 and telescopic components 261 corresponds accordingly. One connection method is that the sleeve 262 is fitted onto one guide member 223, and the two guide members 223 are located on the left and right sides of the transmission member 222, with the sleeve 262 fitted onto the left guide member 223. The first moving block 23 and the second moving block 24 are slidably connected to the right guide member 223.

[0044] In some embodiments, such as Figure 3As shown, the second movable block 24 includes a movable part 241 and a mounting platform 242. The movable part 241 is connected to the first movable block 23 via a first elastic member 25. The mounting platform 242 is fixedly connected to the movable part 241 and connected to the fire hose model 3. The movable part 241 is also fixedly connected to the sleeve 262, slidably connected to the guide member 223, and non-contactly sleeved with the power member 221. The movable part 241 has corresponding mounting holes for installation. Similarly, the first movable block 23 also has corresponding mounting holes for installation with the sleeve 262, guide member 223, and transmission member 222. The structure of the mounting platform 242 is adapted to the installation location of the fire hose model 3, for example, it is a plate. The fire hose model 3 is welded and fixed to the mounting platform 242.

[0045] In some embodiments, such as Figure 3 As shown, the recoil simulation component 2 also includes several buffer members 265. At least one buffer member 265 is located at the rear end of the second moving block 24 away from the first moving block 23, for example, fixed to the inner wall of the housing 21, which can prevent the first moving block from impacting the housing 21 and causing damage. At least one buffer member 265 is located at the front end of the first moving block 23 away from the second moving block 24. For example, the buffer member 265 is fixed to the rear side of the limiting member 264, that is, located between the limiting member 264 and the first moving block 23, which can prevent damage to the first moving block 23 and the limiting member 264.

[0046] In use, the motor drives the screw to rotate, thereby moving the first moving block 23 backward. The user moves the fire hose model 3 forward, while the second moving block 24, along with the sleeve 262, moves forward. The sleeve 262 contacts the locking block 2615 through the slot 263, causing the locking block 2615 to retract into the mounting block 2611. When the sleeve 262 stops moving, the locking block 2615 engages with the slot 263 under the action of the second elastic element 2616, limiting the positions of the second moving block 24 and the fire hose model 3. As the first moving block 23 and the second moving block 24 move towards each other, the second moving block 23 and the first moving block 24 compress the first elastic element 25, increasing the elastic force of the first elastic element 25. The locking component 26 can be used to prevent the elastic force of the first elastic element 25 from injuring the user when it resets.

[0047] After the user has finished using the device, rotating the internal thread cap 2614 will move the mounting rod 2612 and the locking block 2615 away from the sleeve 262, causing the locking block 2615 to be pulled out of the slot 263, thus releasing the restriction on the second moving block 24 and the fire nozzle model 3. This will prevent the fire nozzle model 3 from resetting and impacting the user after the user pushes it away.

[0048] In some embodiments, such as Figures 1 to 3As shown, the rotating structure 4 includes a mounting sleeve 41 and a ball 42. The ball 42 is movably disposed through the bottom end of the mounting sleeve 41 and fixedly connected to the base 1. The mounting sleeve 41 is fixedly connected to the bottom end of the housing 21. The base 1 includes a base plate and a support rod 12, with the support rod 12 fixedly connected to the base plate. The base plate has several mounting holes for mounting and fixing the base plate to an external structure. The bottom end of the ball 42 is fixedly connected to the support rod 12. By setting the ball 42 in conjunction with the mounting sleeve 41, the fire hose model 3 can move to accommodate the user's gripping posture. The support rod 12 can be composed of multiple rods, such as multiple inserted rods or multiple rods forming a telescopic structure, allowing for height adjustment.

[0049] By implementing this utility model, the following beneficial effects can be achieved:

[0050] This utility model's fire hose recoil simulation device uses a power component 22 to move a first moving block 23, simultaneously moving a first elastic element 25 and a second moving block 24. To keep the second moving block 24 in a fixed position, an external force must be applied to the fire hose model 3, simultaneously acting on the second moving block 24. At this time, the first elastic element 25 compresses, generating an elastic force. The external force must be equal to the elastic force to counteract the elastic force of the first elastic element. This elastic force simulates the recoil. This achieves the effect of simulating the recoil of a fire hose during use, making the training experience more realistic.
