Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, specifically relating to a quick-connect vehicle-mounted water gun bracket for fire protection. Background Technology

[0002] A fire truck-mounted water nozzle bracket is a device specifically designed for mounting and supporting fire hoses on fire trucks. It securely holds the fire hose to the fire truck, ensuring stability and accuracy of the spray during firefighting. This is especially important in scenarios requiring a directional, high-flow-rate water supply. The bracket's design typically prioritizes ease of operation for firefighters, reducing their workload. Fire truck-mounted water nozzle brackets are suitable for extinguishing large-area fires, high-rise building fires, and fire scenarios with explosion hazards that are difficult to access. It helps firefighters conduct firefighting operations more effectively.

[0003] A significant problem with existing fire truck hose mounts is the lack of a folding mechanism in their structural design. This crucial design deficiency prevents the mount from being easily folded when not in use. When mounted on the roof of a fire truck, the non-foldable nature of the mount significantly increases the overall height of the vehicle. This not only affects the fire truck's maneuverability in complex urban environments—such as bridges, tunnels, or underground parking garages with height restrictions—but also limits its rapid response and efficient rescue capabilities.

[0004] Furthermore, because the support frame is constantly exposed to the external environment without the necessary folding and storage protection, it is continuously subjected to erosion from natural factors such as wind, sun, and rain. Over time, the surface coating of the support frame will gradually peel off, and the metal parts will easily rust and corrode, greatly increasing the risk of damage to the support frame. Once the support frame is damaged, it will not only affect the normal use of the water gun and reduce the fire extinguishing efficiency, but may also require temporary repair or replacement during emergency rescue missions, which will undoubtedly bring great inconvenience and potential safety hazards to firefighting work. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-connect vehicle-mounted water gun bracket for fire fighting, which aims to solve the problem that current vehicle-mounted water gun brackets for fire fighting lack folding function, making it impossible to fold the bracket conveniently when not in use. When the vehicle-mounted water gun bracket is installed on the roof of a fire truck, its non-foldable characteristic will significantly increase the overall height of the vehicle. At the same time, the bracket is exposed to the external environment for a long time without the necessary folding and storage protection, and will be continuously corroded by natural factors such as wind, sun and rain.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect vehicle-mounted water gun bracket for fire fighting, comprising a mounting base, a support assembly connected to the surface of the mounting base, a clamping assembly at the top of the support assembly, and the support assembly connected to the mounting base via a folding assembly; the folding assembly comprises a vertical plate, a first rotating shaft, a driven gear, a power motor, and a driving gear; the vertical plate is connected to the surface of the mounting base, and the first rotating shaft connected to the side surface of the support assembly passes through the interior of the vertical plate; the driven gear is connected to the bottom of the support assembly; the power motor is mounted on the surface of the mounting base, and the output end of the power motor is connected to a driving gear that meshes with the driven gear.

[0007] To limit the movement direction of the extension tube, as a quick-connect vehicle-mounted water gun bracket for fire fighting according to this utility model, preferably, the support assembly includes a support tube, an extension tube, a sliding groove, a slide rail, and a telescopic rod. The inner wall of the support tube is inserted with an extension tube whose inner wall size matches the extension tube's size. The inner wall of the extension tube is provided with a sliding groove, and the inner wall of the support tube is connected to a slide rail that matches the sliding groove.

[0008] To facilitate the adjustment of the height of the extension tube, as a quick-connect vehicle-mounted water gun bracket for fire fighting according to this utility model, preferably, a telescopic rod connected to the extension tube is installed on the inner wall of the support tube, so that the telescopic rod drives the extension tube to move axially.

[0009] As a quick-connect vehicle-mounted water gun bracket for fire fighting according to this utility model, preferably, the clamping assembly includes a first clamping plate, a hinge, a second clamping plate, a threaded rod, a strip groove and a fastening screw tube. The side surface of the first clamping plate is connected to the hinge, and the side surface of the hinge is connected to the second clamping plate, so that the second clamping plate can rotate about the hinge central axis.

[0010] To facilitate the merging of the first and second clamping plates for holding the water gun, as a quick-connect vehicle-mounted water gun bracket for fire fighting according to this utility model, preferably, the surface of the first clamping plate is provided with a strip groove, and a threaded rod connected to the side surface of the second clamping plate passes through the inside of the strip groove. The surface of the threaded rod is fitted with a fastening threaded tube of a suitable size.

[0011] In order to enable the rotating bracket to rotate horizontally, as a quick-connect vehicle-mounted water gun bracket for fire fighting according to this utility model, preferably, the support component and the clamping component are connected by a rotating component. The rotating component includes a second rotating shaft, a bearing, a rotating bracket, a third rotating shaft, a connecting seat and a spring bar. The end of the support component is connected to the second rotating shaft, and the surface of the second rotating shaft is sleeved with a bearing, which is fitted and installed inside the rotating bracket.

[0012] In order to enable the clamping assembly to drive the connecting seat to rotate vertically, as a quick-connect vehicle-mounted water gun bracket for fire fighting according to this utility model, preferably, the rotating bracket has a third rotating shaft symmetrically passing through both sides, and the two third rotating shafts are connected to the two sides of the connecting seat at their closest points, and the connecting seat is connected to the bottom side of the clamping assembly.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, when the first rotating shaft is running, it generates a force on the driven gear through the driving gear. When the driven gear is subjected to the force, it generates a force on the support component. When the support component is subjected to the force, it drives the first rotating shaft to rotate inside the upright plate. When the support component rotates, it can drive the clamping component to rotate through the rotating component. When the support component rotates 90°, the water gun bracket can be folded, which makes it convenient to store the water gun bracket when it is not in use.

[0015] In this invention, after the water gun head is inserted between the first clamping plate and the second clamping plate, the fastening screw tube is rotated. When the fastening screw tube rotates, it drives the threaded rod to move axially and generates a pulling force on the second clamping plate. The second clamping plate, under the pulling force, can rotate towards the first clamping plate to clamp the water gun head, thereby making it convenient and quick to clamp and fix the water gun head.

[0016] In this invention, when the telescopic rod extends, it squeezes the extension cylinder to move upward. The upward movement of the extension cylinder drives the clamping component to move upward through the rotating component. The upward movement of the clamping component drives the water gun head it clamps to move longitudinally. This allows for convenient adjustment of the height of the water gun head according to the distance of the fire extinguishing.

[0017] This invention uses a clamping assembly and a connecting seat to drive a third rotating shaft to rotate inside a rotating bracket. At the same time, the clamping assembly is subjected to a horizontal force, which can drive a second rotating shaft to rotate inside a bearing via the connecting seat, the third rotating shaft, and the rotating bracket. This allows for convenient multi-angle adjustment of the water gun head held by the clamping assembly according to the fire extinguishing position. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-7 The present invention provides the following technical solution: a quick-connect vehicle-mounted water gun bracket for fire fighting, including a mounting base 1, a support component 2 connected to the surface of the mounting base 1, a clamping component 3 provided on the top of the support component 2, and the support component 2 connected to the mounting base 1 through a folding component 4; the folding component 4 includes a vertical plate 401, a first rotating shaft 402, a driven gear 403, a power motor 404 and a driving gear 405, the vertical plate 401 is connected to the surface of the mounting base 1, the first rotating shaft 402 connected to the side surface of the support component 2 passes through the interior of the vertical plate 401, the driven gear 403 is connected to the bottom of the support component 2, the power motor 404 is mounted on the surface of the mounting base 1, and the output end of the power motor 404 is connected to a driving gear 405 that meshes with the driven gear 403;

[0029] When in use, the vehicle-mounted water gun bracket is first installed on the roof of the fire truck through the mounting holes on the surface of the mounting base 1. Then, the water gun head can be clamped and fixed through the clamping component 3 of the water gun bracket, and then water is sprayed through the water gun head to extinguish the fire.

[0030] Preferably, the support assembly 2 includes a support cylinder 201, an extension cylinder 202, a sliding groove 203, a slide rail 204, and a telescopic rod 205. The inner wall of the support cylinder 201 is inserted with an extension cylinder 202 that matches its inner wall size. The inner wall of the extension cylinder 202 is provided with a sliding groove 203. The inner wall of the support cylinder 201 is connected with a slide rail 204 that matches the sliding groove 203.

[0031] In practical use, when the extension cylinder 202 is subjected to a force, it can drive the sliding groove 203 to slide on the surface of the slide rail 204. In this way, the sliding of the extension cylinder 202 on the inner wall of the support cylinder 201 can be restricted by the limiting effect of the slide rail 204 and the sliding groove 203, thereby ensuring the stability of the movement of the extension cylinder 202.

[0032] Preferably, a telescopic rod 205 connected to the extension cylinder 202 is installed on the inner wall of the support cylinder 201 so that the telescopic rod 205 drives the extension cylinder 202 to move axially.

[0033] In practical use, the extension tube 202 can be driven to move longitudinally when it is running, so the height of the extension tube 202 can be adjusted by the operation of the extension tube 202.

[0034] Preferably, the clamping assembly 3 includes a first clamping plate 301, a hinge 302, a second clamping plate 303, a threaded rod 304, a strip-shaped groove 305, and a fastening screw tube 306. The side surface of the first clamping plate 301 is connected to the hinge 302, and the side surface of the hinge 302 is connected to the second clamping plate 303, so that the second clamping plate 303 can rotate around the central axis of the hinge 302.

[0035] In practical use, when the second clamping plate 303 is subjected to force, it rotates around the central axis of the hinge 302 in a direction closer to the first clamping plate 301. In this way, the water gun head can be clamped and fixed by the closing of the first clamping plate 301 and the second clamping plate 303.

[0036] Preferably, the surface of the first clamping plate 301 is provided with a strip groove 305, and a threaded rod 304 of the side surface of the second clamping plate 303 of the connecting seat passes through the inside of the strip groove 305. A fastening screw tube 306 of the same size is sleeved on the surface of the threaded rod 304.

[0037] In practical use, the rotation of the fastening screw tube 306 can drive the threaded rod 304 to move axially inside it through the threaded connection. The movement of the threaded rod 304 can generate a pulling force on the second clamping plate 303 and rotate it towards the first clamping plate 301.

[0038] Preferably, the support assembly 2 and the clamping assembly 3 are connected by a rotating assembly 5. The rotating assembly 5 includes a second rotating shaft 501, a bearing 502, a rotating bracket 503, a third rotating shaft 504, a connecting seat 505, and a spring bar 506. The end of the support assembly 2 is connected to the second rotating shaft 501. The surface of the second rotating shaft 501 is fitted with the bearing 502, and the bearing 502 is fitted into the interior of the rotating bracket 503.

[0039] In practical use, when the rotating bracket 503 is subjected to a force, it can drive the second rotating shaft 501 to rotate inside the bearing 502, thus enabling the rotating bracket 503 to rotate horizontally.

[0040] Preferably, the rotating bracket 503 has symmetrical third rotating shafts 504 extending through both sides, and the two third rotating shafts 504 are connected to the two sides of the connecting seat 505 at their closest points. The connecting seat 505 is connected to the bottom side of the clamping assembly 3.

[0041] In practical use, when the connecting seat 505 is subjected to a force, it can drive the third rotating shaft 504 to rotate vertically inside the rotating bracket 503. When the connecting seat 505 rotates, it can pull the spring strip 506 to deform.

[0042] The working principle of this utility model in specific use is as follows: When using this fire truck water gun bracket, first install the bracket on the top of the fire truck through the mounting hole of the mounting base 1. Then insert the water gun head between the first clamping plate 301 and the second clamping plate 303. Then, the fastening screw tube 306 can be rotated. When the fastening screw tube 306 rotates, it can drive the threaded rod 304 to move axially inside the fastening screw tube 306. In this way, the threaded rod 304 can generate a pulling force on the second clamping plate 303. The second clamping plate 303 can rotate towards the first clamping plate 301 under the pulling force. When the first clamping plate 301 and the second clamping plate 303 move to both sides of the water gun head, the water gun head can be clamped by the first clamping plate 301 and the second clamping plate 303.

[0043] During firefighting operations, the clamping assembly 3 and the connecting seat 505 can drive the third rotating shaft 504 to rotate inside the rotating bracket 503 and pull the spring strip 506 to deform. At the same time, the clamping assembly 3 is subjected to a horizontal force, which can drive the second rotating shaft 501 to rotate inside the bearing 502 through the connecting seat 505, the third rotating shaft 504, and the rotating bracket 503. This allows for convenient multi-angle adjustment of the water gun head clamped by the clamping assembly 3 according to the firefighting position.

[0044] During the use of the vehicle-mounted water gun bracket, the telescopic rod 205 can be operated. When the telescopic rod 205 extends, it can squeeze the extension cylinder 202 to move upward. The upward movement of the extension cylinder 202 can drive the clamping component 3 to move upward through the rotating component 5. The upward movement of the clamping component 3 can drive the water gun head it clamps to move longitudinally. This makes it convenient to adjust the height of the water gun head according to the distance of the fire extinguishing.

[0045] After the vehicle-mounted water gun bracket is used, the first rotating shaft 402 can be operated. When the first rotating shaft 402 is running, it can drive the drive gear 405 to rotate. The rotation of the drive gear 405 can generate a force on the driven gear 403 through the meshing structure. When the driven gear 403 is subjected to a force, it can generate a force on the support component 2. When the support component 2 is subjected to a force, it can drive the first rotating shaft 402 to rotate inside the upright plate 401. When the support component 2 rotates, it can drive the clamping component 3 to rotate through the rotating component 5. When the support component 2 rotates 90°, the water gun bracket can be folded.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
