Description

Technical Field

[0001] This utility model belongs to the field of fire extinguisher shock absorption technology, and in particular relates to a shock absorption device for vehicle-mounted fire extinguishers. Background Technology

[0002] Vehicle-mounted fire extinguishers are portable fire-fighting devices specifically designed for vehicle fire suppression. The main types include dry powder, ultrafine dry powder, carbon dioxide, and water-based fire extinguishers. Their core function is to quickly suppress, control, or extinguish initial fires in vehicles, ensuring the safety of drivers and passengers. However, the continuous vibrations generated during vehicle operation can cause the pressure gauge pointer inside the fire extinguisher to deviate, seals to loosen, or even cause agent precipitation or leakage, affecting the reliability and effectiveness of the fire extinguisher. Therefore, shock-absorbing and fixing devices are needed to limit the installation of vehicle-mounted fire extinguishers.

[0003] Chinese patent publication number 202421115748.1 discloses a shock-absorbing device for vehicle-mounted fire extinguishers, comprising a vehicle, a connecting box, and a storage tank. The connecting box is installed on the outer wall of the vehicle, and the storage tank is located inside the connecting box. A fire extinguisher is installed inside the storage tank. A movable structure is located below the outer wall of the fire extinguisher and is installed inside the connecting box. The movable structure includes a rubber block, a fixing plate, and a shock-absorbing spring. Multiple protective cotton pads are provided on the outer side of the fire extinguisher. The protective cotton pads are located on the outer wall of the fixing block, and a fixing post is installed on the outer side of the fixing block. The fixing post passes through the fixing slot and connects to the connecting plate. The two sides of the connecting plate are located inside the sliding groove. This utility model can be used for fire extinguishers of different diameters, improving the applicability of the device and facilitating the protection of the outer wall of the fire extinguisher.

[0004] However, existing technologies have the following problems when used: 1. Most existing vehicle-mounted fire extinguishers are simply fixed or placed directly, lacking targeted shock-absorbing and restraining structures. Vibrations generated by vehicle movement can easily cause fire extinguishers to shift, collide, or even suffer structural damage, affecting their reliability in emergency use. 2. Traditional fixed devices cannot be adapted to different sizes of fire extinguishers, have poor versatility, and the shock absorption structure has limited buffering effect. The reciprocating resonance of the spring can easily reduce the shock absorption efficiency, making it difficult to provide stable and comprehensive vibration protection for the fire extinguisher. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a shock-absorbing device specifically for vehicle-mounted fire extinguishers, comprising: The mounting plate forms a detachable fixed fit with the vehicle's load-bearing surface; The constraint assembly includes a bearing plate slidably mounted on a fixed plate, a shock-absorbing assembly for buffering the bearing plate, and a first limiting part and a second limiting part respectively connected to both ends of the bearing plate; A base is located at the bottom of a fixed plate. Inside the base are a support seat for supporting the fire extinguisher and an elastic column for shock absorption of the fire extinguisher. The outer side of the elastic column has a spirally extending groove structure. A second spring is provided between the top and bottom of the elastic column, and the second spring is adapted to the groove structure. A shock absorber is provided at the bottom of the support seat. The support seat is fixed to the elastic column through the shock absorber. The support seat, together with the shock absorber and the elastic column, is used to absorb the shock of the fire extinguisher placed on the support seat.

[0006] Furthermore, the fixed plate has support grooves at both ends of its sidewall, and the bearing plate has movable blocks that slide within the support grooves at both ends of its sidewall.

[0007] Furthermore, the shock absorption assembly includes a first damping rod and a first spring. The first damping rod is fixedly connected to the bottom of the inner cavity of the support groove. Both the first damping rod and the first spring are fixedly connected between the bottom of the inner cavity of the support groove and the bottom of the movable block. The first spring is sleeved on the outside of the first damping rod.

[0008] Furthermore, the support plate is provided with an adjusting member for adjusting the position of the first limiting part. The adjusting member includes a positioning piece and multiple positioning holes. The multiple positioning holes are distributed along the length direction of the support plate. The positioning piece is located at one end of the first limiting part. The positioning piece is N-shaped and is adapted to the multiple positioning holes.

[0009] Furthermore, a locking block is rotatably provided at the other end of the first limiting part. The locking block is L-shaped. An mounting plate is rotatably provided at one end of the second limiting part. An insert is fixedly provided on the side wall of the mounting plate. A slot adapted to the insert is provided on the side wall of the locking block.

[0010] Furthermore, the top of the base is provided with an installation groove, and the elastic column is fixedly installed in the inner cavity of the installation groove.

[0011] Furthermore, a first connector and a second connector are fixedly provided at the upper and lower ends of the side wall of the elastic column, respectively. The second spring is fixedly provided between the first connector and the second connector. A spiral shell is fixedly provided between the first connector and the second connector, and the spiral shell is sleeved on the outside of the second spring.

[0012] Furthermore, a second damping rod is fixedly installed at the middle of the bottom of the inner cavity of the mounting groove, and a buffer cavity supporting the second damping rod is provided in the inner cavity of the elastic column. The top end of the second damping rod is fixedly installed with the bottom of the bearing seat.

[0013] Furthermore, the shock absorber is annular in shape, and the lower end of the inner wall of the shock absorber is provided with an angled portion.

[0014] Furthermore, the side wall of the fixing plate is provided with mounting holes.

[0015] Compared with existing technologies, the shock absorption device for vehicle-mounted fire extinguishers described in this utility model has the following advantages: The first and second limiting parts at both ends of the bearing plate form a lateral constraint space. With the adjustable positioning plate and positioning hole structure, it can be adapted to different specifications of fire extinguishers, improving the versatility of the device. At the same time, the interlocking of the L-shaped locking block and the insert plate enhances the constraint stability and prevents the fire extinguisher from shifting due to vibration. By constructing a multi-stage damping system, the first damping rod and the first spring at the bottom of the bearing plate work together to buffer the vibration impact force through spring compression and suppress resonance with the help of the damping rod; the elastic column, the second spring, the spiral shell and the second damping rod in the base form a three-dimensional damping structure. Combined with the force dispersion effect of the annular damping component, it can absorb the vibration energy of the fire extinguisher and solve the problem of insufficient buffering of traditional damping structures. The bearing plate, through the guiding cooperation of the movable block and the support groove, ensures a smooth and non-displaced vibration reduction process. The overall structure ensures that the fire extinguisher is not easily damaged in a vibration environment, thus improving the reliability of emergency use. Attached Figure Description

[0022] like Figures 1-5 As shown, a shock-absorbing device specifically for vehicle-mounted fire extinguishers includes: The fixing plate 100 forms a separable fixing fit with the vehicle bearing surface. Specifically, it can be fixed to the vehicle bearing surface by bolts or Velcro. The constraint assembly provided on the fixed plate 100 includes a bearing plate 130 slidably disposed on the fixed plate 100, a shock-absorbing assembly for buffering the bearing plate 130, and a first limiting part 140 and a second limiting part 150 respectively connected to both ends of the bearing plate 130. The base 200 is fixedly installed at the bottom of the fixing plate 100. Inside the base 200, a support seat 260 for supporting the fire extinguisher and an elastic column 230 for damping the fire extinguisher are fixedly installed. The outer side of the elastic column 230 has a spirally extending groove structure 231. A second spring 241 is provided between the top and bottom of the elastic column 230. The second spring 241 is adapted to the groove structure 231. A shock absorber 261 is provided at the bottom of the support seat 260. The support seat 260 is fixedly installed with the elastic column 230 through the shock absorber 261. The support seat 260, together with the shock absorber 261 and the elastic column 230, is used to dampen the fire extinguisher installed on the support seat 260.

[0023] As a preferred example of this utility model, the support plate 130, together with the shock-absorbing component at the bottom, can buffer and dampen the fire extinguisher. The first limiting part 140 and the second limiting part 150 at both ends together form a lateral constraint space. The adjusting part on the support plate 130 can adjust the position of the first limiting part 140 according to the fire extinguisher specifications. The base 200 serves as the bottom support structure, and the support seat 260 inside it directly supports the fire extinguisher. The spiral groove structure 231 on the outside of the elastic column 230 is adapted to the second spring 241 that runs through the top and bottom of the column. Together with the shock-absorbing component 261 at the bottom of the support seat 260, they form a multi-stage shock absorption system. When the vehicle vibrates, the elastic deformation of the elastic column 230, the extension and contraction of the second spring 241, and the buffering effect of the shock-absorbing component 261 are superimposed to absorb vibration energy and prevent the fire extinguisher from shifting or being structurally damaged due to vibration.

[0024] In the example of this application, the side wall of the fixed plate 100 is provided with support grooves 120 at both ends, and the side wall of the bearing plate 130 is provided with movable blocks 131 that slide in the support grooves 120 at both ends.

[0025] As a preferred example of this utility model, movable blocks 131 are integrally provided at both ends of the side wall of the support plate 130. The movable blocks 131 are embedded in the support groove 120 and can slide along the groove, providing guidance for the up and down buffering movement of the support plate 130. This can prevent problems such as lateral displacement, tilting or shaking of the support plate 130 during the shock absorption process, and ensure that the support plate 130 drives the fire extinguisher to complete the buffering action smoothly.

[0026] In the example of this application, the shock absorption assembly includes a first damping rod 121 and a first spring 122. The first damping rod 121 is fixedly connected to the bottom of the inner cavity of the support groove 120. The first damping rod 121 and the first spring 122 are both fixedly connected between the bottom of the inner cavity of the support groove 120 and the bottom of the movable block 131. The first spring 122 is sleeved on the outside of the first damping rod 121.

[0027] As a preferred example of this utility model, the shock absorption assembly adopts a combination of a first damping rod 121 and a first spring 122. The first damping rod 121 is vertically fixed to the bottom of the inner cavity of the support groove 120, and the first spring 122 is sleeved on the outside of the first damping rod 121. The top ends of both are fixedly connected to the bottom of the movable block 131 of the bearing plate 130. When the bearing plate 130 moves downward under vibration pressure, the first spring 122 will generate a reverse elastic force due to compression, directly buffering the transmitted vibration impact force and achieving initial shock absorption. The first damping rod 121 can use its own damping characteristics to suppress the reciprocating resonance phenomenon of the spring after shock absorption. The synergistic effect of the spring and the damping rod enhances the buffering and shock absorption performance of the device. Specifically, the damping rod is a mechanical element that converts vibration energy into heat energy or other forms of energy through internal viscous damping oil, thereby suppressing mechanical or structural vibration. The model can be a JEIACS series damping rod.

[0028] In the example of this application, the support plate 130 is provided with an adjusting member for adjusting the position of the first limiting part 140. The adjusting member includes a positioning piece 141 and a plurality of positioning holes 132. The plurality of positioning holes 132 are distributed along the length direction of the support plate 130. The positioning piece 141 is disposed at one end of the first limiting part 140. The positioning piece 141 is N-shaped and is adapted to the plurality of positioning holes 132.

[0029] As a preferred example of this utility model, the adjusting component consists of a positioning piece 141 and multiple positioning holes 132. The multiple positioning holes 132 are evenly distributed along the length of the support plate 130, forming a multi-position adjustment base. The positioning piece 141 is fixed to one end of the first limiting part 140, and its overall structure is N-shaped, allowing it to form a tight engagement with the positioning holes 132. When it is necessary to adapt to vehicle fire extinguishers of different lengths, simply remove the positioning piece 141, move the first limiting part 140 to the appropriate position, and then insert the positioning piece 141 into the corresponding positioning hole 132. The first limiting part 140 can be locked in position, which not only greatly improves the versatility of the device, but also ensures the stability of the first limiting part 140 position by the tight fit between the N-shaped positioning piece 141 and the positioning hole 132, preventing it from loosening during use. Specifically, the N-shaped structure of the positioning piece 141 can be inserted into the positioning hole 132, and through rotation, the positioning piece 141 is limited in the positioning hole 132. When the first limiting part 140 is connected and limited with the second limiting part 150, it will limit the rotated N-shaped positioning piece 141, thereby achieving fixation.

[0030] In the example of this application, a locking block 142 is rotatably provided at the other end of the first limiting part 140. The locking block 142 is L-shaped. An mounting piece 151 is rotatably provided at one end of the second limiting part 150. An insert piece 152 is fixedly provided on the side wall of the mounting piece 151. A slot 143 adapted to the insert piece 152 is provided on the side wall of the locking block 142.

[0031] As a preferred example of this utility model, the other end of the first limiting part 140 is rotatably provided with an L-shaped locking block 142 via a rotating shaft and a torsion spring, and one end of the second limiting part 150 is rotatably provided with a mounting plate 151 via a rotating shaft and a torsion spring. The side wall of the mounting plate 151 is integrally formed with an insert 152, while the side wall of the locking block 142 has a locking groove 143 that matches the insert 152. The inner cavity of the locking groove 143 is divided into a narrow end and a wide end. When the fire extinguisher is placed on the support plate 130 and passed through the first, After the second limiting part completes the initial limiting, the insert 152 is inserted into the wide end of the slot 143. Then, the L-shaped card block 142 and the mounting piece 151 are rotated in the same direction, and the L-shaped card block 142 is attached to the first limiting part 140, and the insert 152 is inserted into the narrow end of the slot 143. It is fixed with the help of the torsion spring. In other embodiments, existing fixing methods such as Velcro and snap fasteners can also be used to fix and limit the first limiting part 140 and the second limiting part 150.

[0032] In the example of this application, the top of the base 200 is provided with a mounting groove 210, and the elastic column 230 is fixedly disposed in the inner cavity of the mounting groove 210.

[0033] As a preferred example of this utility model, the top of the base 200 is specially provided with a mounting groove 210 that matches the size of the elastic column 230, and the elastic column 230 is embedded and fixed in the inner cavity of the mounting groove 210.

[0034] In the example of this application, a first connector 220 and a second connector 240 are fixedly provided at the upper and lower ends of the side wall of the elastic column 230, respectively. A second spring 241 is fixedly provided between the first connector 220 and the second connector 240. A spiral shell 270 is fixedly provided between the first connector 220 and the second connector 240. The spiral shell 270 is sleeved on the outside of the second spring 241.

[0035] As a preferred example of this utility model, the upper and lower ends of the side wall of the elastic column 230 are respectively fixed with a first connector 220 and a second connector 240. The two ends of the second spring 241 are respectively fixedly connected to the two connectors to ensure that the spring and the elastic column 230 are firmly connected. At the same time, the spiral groove structure 231 on the outside of the elastic column 230 is adapted to the spiral direction of the second spring 241, so that the spring can fit the groove and be installed, and the force is more even. A spiral shell 270 is also fixedly provided between the first connector 220 and the second connector 240. The spiral shell 270 is sleeved on the outside of the second spring 241, which can suppress the reciprocating vibration of the second spring 241 after expansion and contraction shock absorption. It forms multiple shock absorptions in combination with the elastic buffer of the elastic column 230. Specifically, the elastic column 230 and the spiral shell 270 are both made of polyurethane material.

[0036] In the example of this application, a second damping rod 250 is fixedly installed at the middle of the bottom of the inner cavity of the mounting groove 210, and a buffer cavity 232 supporting the second damping rod 250 is provided in the inner cavity of the elastic column 230. The top end of the second damping rod 250 is fixedly installed with the bottom of the bearing seat 260.

[0037] As a preferred example of this utility model, a second damping rod 250 is vertically fixed at the middle of the bottom of the inner cavity of the mounting groove 210, and a buffer cavity 232 that runs vertically through the inner cavity of the elastic column 230 is provided. The diameter of the buffer cavity 232 is slightly larger than the diameter of the second damping rod 250, providing sufficient space for the extension and retraction of the second damping rod 250. The top of the second damping rod 250 is directly fixedly connected to the bottom center of the support seat 260. When the support seat 260 is subjected to vibration and downward pressure, the second damping rod 250 will retract accordingly and generate damping force, providing longitudinal buffer support from below the support seat 260. Together with the elastic column 230, the shock absorber 261, and other structures, it forms a three-dimensional shock absorption system, enhancing the device's ability to buffer the longitudinal vibration of the fire extinguisher.

[0038] In the example of this application, the shock absorber 261 is annular in shape, and the lower end of the inner sidewall of the shock absorber 261 is provided with an angled portion 262.

[0039] As a preferred example of this utility model, the shock absorber 261 at the bottom of the support 260 has an overall ring structure, which can form contact with the bottom of the support 260 and the top of the elastic column 230. When the vibration impact force is transmitted, the ring structure can distribute the force to the entire shock absorber 261. At the same time, the lower end of the inner side wall of the shock absorber 261 is provided with a beveled part 262. When the force is applied, the beveled part 262 will deform towards the inside of the shock absorber 261, thereby playing a shock absorption role and ensuring that the shock absorption force can be transmitted and absorbed. The shock absorber 261 is made of silicone material. Specifically, the shock absorber 261 forms a buffer space with the support 260 through the beveled part 262.

In actual installation, simply pass the bolts or other fasteners through the mounting holes 110 and connect them to the preset mounting points on the vehicle's bearing surface to complete the assembly of the fixing plate 100 with the vehicle. Alternatively, Velcro can be used to fix the fixing plate 100.

[0042] In practical use, the fixing plate 100 has mounting holes 110 on its side wall, which can be used to form a detachable fixing with the vehicle bearing surface by bolts or Velcro. Support grooves 120 are formed at both ends of the side wall of the fixing plate 100. A first damping rod 121 is fixedly connected to the bottom of the inner cavity of the support groove 120. A first spring 122 is sleeved on the outer side of the first damping rod 121. The top ends of the first damping rod 121 and the first spring 122 are connected to a movable block 131.
