Description

Technical Field

[0001] This utility model belongs to the field of new energy rescue vehicle technology, specifically relating to a multi-functional quick-change bracket for rescue vehicles. Background Technology

[0002] New energy rescue vehicles refer to emergency rescue vehicles that use new energy drive systems, typically employing environmentally friendly energy sources such as electricity and hydrogen. These vehicles exhibit lower carbon emissions and higher energy efficiency during emergency rescue operations, aligning with the current trend towards green transportation. During rescue operations, rescue vehicle brackets are commonly used to support and secure vehicle components, instruments, and tools to address complex on-site situations.

[0003] Currently, most of these brackets are installed on rescue vehicles using fixed supports or storage boxes. However, the brackets have poor applicability; one type of support can usually only install one type of equipment, making it difficult to flexibly adapt to changes in mission requirements. Furthermore, the existing brackets are inefficient to replace, requiring cumbersome disassembly and assembly with tools, which cannot achieve rapid replacement, wasting time and delaying the rescue process. Utility Model Content

[0004] The purpose of this invention is to provide a multi-functional quick-change bracket for rescue vehicles, which can be flexibly adjusted according to rescue needs, improving its flexibility, and enabling quick disassembly and replacement of the bracket, thereby improving rescue efficiency.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A multi-functional quick-change bracket for a rescue vehicle includes a column, a base frame installed on the inner side of the column, two base rails installed on the top of the base frame, two bracket bodies slidably connected to the top of the two base rails respectively, connecting plates installed on the top and bottom of the inner sides of the two bracket bodies, each connecting plate having a positioning groove on its top, round holes on the outer sides of the two bracket bodies, several crossbeams installed on the inner sides of the two bracket bodies, both ends of the crossbeams slidably connected between the connecting plates, structural grooves being formed at both ends of the crossbeams, an adjustment and positioning mechanism being provided inside the structural grooves, and a quick-release mechanism being provided on the top of the base frame.

[0007] The adjustment and positioning mechanism includes a return spring connected to the inner wall of the structural groove. The other end of the return spring is connected to a fixed block. The top and bottom of the fixed block are connected to external support rods via rotating shafts. The other ends of the two external support rods are respectively connected to moving blocks via rotating shafts. The two moving blocks are slidably connected to the outer side of the inner wall of the structural groove. Two baffles are fixedly connected to the outer side of the inner wall of the structural groove. The two moving blocks are slidably connected between the two baffles. Two positioning rods are fixedly connected to the outer side of the two moving blocks. The other ends of the two positioning rods pass through the crossbeam and extend into the interior of the positioning groove. A guide rod is fixedly connected to the inner wall of the structural groove. A connecting block is slidably connected to the surface of the guide rod. The connecting block is fixedly connected to the front and rear sides of the fixed block. The front connecting block passes through to the front side of the crossbeam, and a handle is fixedly connected to the front side of the connecting block.

[0008] Preferably, the quick-release mechanism includes a vertical plate connected to the top of the bottom frame, a round rod slidably connected inside the vertical plate, one end of the round rod being located on the outside of the vertical plate, the other end of the round rod penetrating into the inside of the round hole, a compression spring being sleeved on the surface of the round rod, one end of the compression spring being fixedly connected to the inside of the vertical plate, and the other end of the compression spring being connected to the round rod.

[0009] Preferably, both of the bracket bodies have an internal groove, which is an n-shaped groove.

[0010] Preferably, rollers are installed inside the two bracket bodies, and the rollers are slidably disposed on the top of the bottom rail.

[0011] Preferably, the front and rear sides of one end of the round rod are both set as inclined surfaces, the inclination angle of the inclined surfaces is thirty-five degrees, and the other end of the round rod is connected to a handle.

[0012] Preferably, a telescopic spring is fixedly connected between the two movable blocks, and the telescopic spring is located between the two baffles.

[0013] Preferably, there are several positioning slots, which are evenly distributed on the top of the connecting plate.

[0014] The technical effects achieved by this utility model are as follows:

[0015] In this invention, when different tools or equipment need to be installed on the bracket, the spacing of the crossbeams can be flexibly adjusted for fixation. During adjustment, the fixing block can be pulled outward by the handle and the return spring can be squeezed. The outward movement of the fixing block will cause the outer ends of the two outer support rods to retract inward, while simultaneously causing the two moving blocks and two positioning rods to move inward and disengage the positioning rods from the positioning slots. Then, the crossbeams can be pulled to slide between the connecting plates as needed, and the spacing of the crossbeams can be adjusted. This allows for the installation of different tools or equipment to meet different rescue needs. After the crossbeams are adjusted, the hand can be released from the handle, and the fixing block can be pushed inward by the elastic force of the return spring. The above steps can be reversed to fit the positioning rods with the corresponding positioning slots, thus quickly adjusting and positioning the crossbeams between the bracket bodies. By adjusting the spacing of the crossbeams, different equipment and tools can be fixedly installed according to rescue needs, improving the flexibility of the bracket during use.

[0016] In this invention, when the bracket needs to be quickly replaced, the two bracket bodies and the inner crossbeam can be pulled forward and slid forward on the top of the bottom rail. When the bracket body squeezes the round rod, it is guided downward by the inclined surface at the end of the round rod. The squeezed round rod moves outward and squeezes the compression spring. When the round rod moves outward, it will disengage from the round hole. Then, the roller smoothly pulls the bracket body off the bottom rail. Then, the new bracket is reinstalled on the bottom rail. With the assistance of the n-shaped groove and the roller, the new bracket body can be smoothly installed on the bottom rail. Then, under the continuous elastic force of the compression spring, the round rod is pushed to fit the round hole, which can fix the bracket body on the bottom rail and prevent the bracket body from shaking due to lack of limit during vehicle operation.

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-4 As shown, a multi-functional quick-change bracket for a rescue vehicle includes a column 1, a base frame 101 installed on the inner side of the column 1, two bottom rails 102 installed on the top of the base frame 101, and two bracket bodies 103 slidably connected to the top of the two bottom rails 102 respectively. Connecting plates 104 are installed on the top and bottom of the inner side of the two bracket bodies 103. The top of each connecting plate 104 is provided with a positioning groove 105. Circular holes 106 are provided on the outer side of the two bracket bodies 103. Several crossbeams 107 are installed on the inner side of the two bracket bodies 103. The two ends of the crossbeams 107 are slidably connected between the connecting plates 104. Structural grooves 2 are provided at both ends of the crossbeams 107. Adjustment and positioning mechanisms are provided inside the structural grooves 2. A quick-release mechanism is provided on the top of the base frame 101. The assembly design of the bracket bodies 103 and the crossbeams 107 can better distribute and allocate the supporting weight, enhance the stability of the overall system, and reduce the possible offset or instability problems under high load operation.

[0025] The adjusting positioning mechanism includes a return spring 201 connected to the inner wall of the structural groove 2. The other end of the return spring 201 is connected to a fixed block 202. The top and bottom of the fixed block 202 are each connected to an outer support rod 203 via a pivot. The other ends of the two outer support rods 203 are respectively connected to moving blocks 204 via pivots. The two moving blocks 204 are slidably connected to the outer side of the inner wall of the structural groove 2. Two baffles 205 are fixedly connected to the outer side of the inner wall of the structural groove 2. The two moving blocks 204 are slidably connected between the two baffles 205. Two positioning rods 206 are fixedly connected to the outer side of the two moving blocks 204. The other end of the structure groove 2 passes through the crossbeam 107 and extends into the interior of the positioning groove 105. A guide rod 207 is fixedly connected to the inner wall of the structure groove 2. A connecting block 208 is slidably connected to the surface of the guide rod 207. The connecting block 208 is fixedly connected to the front and rear sides of the fixing block 202. The front connecting block 208 passes through the front side of the crossbeam 107, and a handle is fixedly connected to the front side of the connecting block 208. By adjusting the use of the positioning mechanism, the bracket can be adjusted according to different types of tasks, so that the bracket can flexibly cope with various types of tasks and perform them efficiently, thereby improving the task diversity and flexibility of the rescue vehicle.

[0026] like Figure 1 and Figure 2 As shown, the quick-release mechanism includes a vertical plate 301 connected to the top of the bottom frame 101. A round rod 302 is slidably connected inside the vertical plate 301. One end of the round rod 302 is located on the outside of the vertical plate 301, and the other end of the round rod 302 passes through the inside of the round hole 106. A compression spring 303 is sleeved on the surface of the round rod 302. One end of the compression spring 303 is fixedly connected to the inside of the vertical plate 301, and the other end of the compression spring 303 is connected to the round rod 302. Rollers 5 are installed inside the two bracket bodies 103. The rollers 5 are slidably located on the top of the bottom rail 102. The quick-release mechanism can be disassembled by a simple push-pull operation. Unlike the traditional complicated disassembly method, the quick-release mechanism can also achieve smooth sliding with the support and assistance of the rollers 5, reducing the resistance caused by friction during operation. It is easy to operate, reduces the dependence on professional tools, and is suitable for use in emergency or high-pressure environments.

[0027] like Figure 1 and Figure 2 As shown, both bracket bodies 103 have internal grooves 4. The grooves 4 are n-shaped grooves. The design of the n-shaped grooves 4 allows the bracket bodies 103 to be adapted to various positioning structures, such as positioning pins, positioning blocks, positioning sleeves, etc., which facilitates positioning when the entire bracket body 103 is replaced and improves the overall interchangeability of the bracket bodies 103.

[0028] like Figure 1 and Figure 2As shown, both the front and rear sides of one end of the round rod 302 are set as inclined surfaces with an inclination angle of 35 degrees. The other end of the round rod 302 is connected to a handle. Under the action of the inclined surfaces, the resistance to the round rod 302 when the bracket body 103 is replaced is reduced, and the round rod 302 can move smoothly outward after being squeezed, and the round rod 302 can disengage from the round hole 106 to get rid of the limitation on the bracket body 103. Under the action of the handle, when the replacement of the bracket body 103 is resisted, the round rod 302 can be pulled outward by the handle, so that the round rod 302 can be quickly disengaged from the positioning of the bracket body 103, and the bracket body 103 can be replaced quickly, improving the rescue efficiency.

[0029] like Figure 3 and Figure 4 As shown, a telescopic spring 6 is fixedly connected between the two moving blocks 204. The telescopic spring 6 is located between the two baffles 205. The telescopic spring 6 can increase the thrust on the two moving blocks 204, so that the moving blocks 204 can stably drive the positioning rod 206 to match the positioning hole, thereby improving the connection stability between the crossbeam 107 and the bracket body 103. Even under different working pressures or vibrations, it can ensure that the crossbeam 107 is always stably connected to the bracket body 103.

[0030] like Figure 3 and Figure 4 As shown, there are several positioning slots 105, which are evenly distributed on the top of the connecting plate 104. When adjusting the spacing of the crossbeams 107, the operator can flexibly select different positioning slots 105 to adjust as needed, and quickly complete the positioning adjustment of the crossbeams 107. This not only simplifies the operation process, but also allows for the fixed installation of different equipment and tools according to rescue needs by adjusting the spacing of the crossbeams 107, which can improve the flexibility of the bracket during use.

[0031] The working principle of this utility model is as follows: When different tools or equipment need to be installed on the bracket, the spacing of the crossbeam 107 can be flexibly adjusted. During adjustment, the fixing block 202 can be pulled outward by the handle, which will compress the return spring 201. The outward movement of the fixing block 202 will cause the outer ends of the two outer support rods 203 to retract inward, while simultaneously causing the two moving blocks 204 and the two positioning rods 206 to move inward, and causing the positioning rods 206 to disengage from the positioning groove 105. Then, the crossbeam 107 can be pulled as needed. The connecting plates 104 slide between each other, and the spacing of the crossbeams 107 is adjusted to accommodate different tools or equipment to meet different rescue needs. After adjusting the crossbeams 107, the hand can be released from the handle, and the fixing block 202 can be pushed inward by the elastic force of the return spring 201. By reversing the above steps, the positioning rod 206 can be matched with the corresponding positioning groove 105, and the crossbeams 107 can be quickly adjusted and positioned between the bracket bodies 103. Furthermore, by adjusting the spacing of the crossbeams 107, the rescue needs can be met. The bracket can be used to fix different equipment and tools, which can improve the flexibility of the bracket during use. When the bracket needs to be quickly replaced, the two bracket bodies 103 and the inner crossbeam 107 can be pulled forward and slid forward on the top of the bottom rail 102. When the bracket body 103 squeezes the round rod 302, it is guided downward by the inclined surface at the end of the round rod 302. The squeezing round rod 302 moves outward and squeezes the compression spring 303 at the same time. When the round rod 302 moves outward, it will disengage from the round hole 106 and then smoothly pass through the roller 5. The bracket body 103 is pulled off and separated from the bottom rail 102. Then, the new bracket is reinstalled on the bottom rail 102. With the assistance of the n-shaped groove 4 and the roller 5, the new bracket body 103 can be smoothly installed on the bottom rail 102. Then, under the continuous elastic force of the compression spring 303, the round rod 302 is pushed to fit with the round hole 106, so that the bracket body 103 can be fixedly installed on the bottom rail 102, avoiding the bracket body 103 from shaking due to lack of limit during vehicle operation.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
