Description

Technical Field

[0001] This utility model relates to the field of fire rescue equipment technology, and in particular to a trolley that can be used for both high-rise and flat-top applications. Background Technology

[0002] If there are no fire-fighting facilities in the residential buildings in urban villages, it means that there is no readily available water source at the fire scene. The water needed for firefighting cannot be directly delivered to the floor or point of origin of the fire. Therefore, it is necessary to use a small cart to lay out the water hoses.

[0003] Before laying the hoses, the storage baskets for storing the hoses need to be installed on the trolley. Different storage baskets with different functions will be installed in different fire situations (such as layered classification storage baskets or large-capacity hose storage baskets). The storage baskets with different functions have different sizes. The loading structure of traditional trolleys is mostly fixed and cannot be flexibly adjusted according to the size of the items. Therefore, a dual-purpose trolley for both high and flat surfaces is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a dual-purpose (high and flat) trolley, which aims to improve the problem that the loading structure of traditional trolleys in the prior art is fixed and cannot be flexibly adjusted according to the size of the storage basket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dual-purpose trolley for both high and low-rise buildings, including a support frame, a ladder wheel provided on the lower rear side of the support frame, and a fixing mechanism provided on the lower front side of the support frame; The fixing mechanism includes a support plate hinged to the lower front side of the support frame. A guide post is fixedly connected to the inner side wall of the support plate. A clamping plate is slidably connected to the outer arc surface of the guide post. A threaded sleeve is fixedly connected to the inner rear side of the support plate. A threaded rod is threadedly connected to the inner wall of the threaded sleeve. The front part of the threaded rod is cylindrical. A rotating plate is rotatably connected to the inner wall of the clamping plate. Two sets of connecting plates are hinged to the rear of the rotating plate. A pressure plate is hinged to the side of each set of connecting plates away from the rotating plate. An installation plate is fixedly connected to the rear of the clamping plate. A limit component is provided at the front of the clamping plate. A contact plate is fixedly connected to the rear of the installation plate. A positioning component is provided at the top of the support plate. A storage basket is in contact with the top of the support plate.

[0006] As a further description of the above technical solution: The limiting assembly includes a limiting block fixedly connected to the front of the clamping plate. The inner wall of the limiting block is elastically connected to a limiting post through a connecting spring. The outer wall of the limiting post penetrates and is slidably connected to the inner wall of the limiting block. Multiple sets of positioning holes are opened at the front of the rotating plate. The bottom end of the limiting post is inserted into the inner wall of the positioning hole.

[0007] As a further description of the above technical solution: The front outer arc surface of the threaded rod is rotatably connected to the inner wall of the clamping plate.

[0008] As a further description of the above technical solution: The front part of the support plate has a through hole that matches the outer arc surface of the front part of the threaded rod, and the outer arc surface of the front part of the threaded rod contacts the inner wall of the through hole.

[0009] As a further description of the above technical solution: The rear protrusion of the pressure plate contacts the upper inner side of the mounting plate, and the top of the pressure plate contacts the top inner side of the clamping plate.

[0010] As a further description of the above technical solution: The outer wall of the mounting plate has circular holes that match the guide posts.

[0011] As a further description of the above technical solution: The rear end of the contact plate contacts the bottom of the storage basket, a support beam is provided in the middle of the storage basket, and the upper protrusion of the pressure plate contacts the support beam.

[0012] As a further description of the above technical solution: The positioning component includes a magnetic block fixedly connected to the upper part of the tray, and a magnetic plate fixedly connected to the front part of the support frame. The magnetic blocks and magnetic plates have opposite magnetic properties on the sides that are close to each other.

[0013] This utility model has the following beneficial effects: 1. In this utility model, through the cooperation between the support frame, ladder wheels and their fixing mechanism, the rotating threaded rod can drive the clamping plate to adjust the spacing along the guide column, which can adapt to storage baskets of different sizes. At the same time, the rotating plate drives the connecting plate to control the opening and closing of the pressure plate. With the help of the limiting component to fix the angle of the rotating plate, the pressing force of the pressure plate can be flexibly adjusted according to the position of the support beam in the middle of the storage basket, which can stably fix the storage basket and meet the tool use needs in different fire-fighting scenarios.

[0014] 2. In this utility model, through the cooperation between the positioning components and other structures, the tray can be quickly reset and stored from the horizontal use state by the opposite polarity adsorption of the magnetic block and the magnetic plate, reducing the space occupied when the trolley is idle, and the storage operation does not require complicated tools, further improving the preparation and closing efficiency before and after fire fighting operations.

[0017] 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.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a dual-purpose (high and flat) trolley, including a support frame 1. This support frame 1 serves as the main frame of the trolley and is made of high-strength metal, providing a stable support foundation for the entire device. A ladder wheel 2 is provided on the lower rear side of the support frame 1. The ladder wheel 2 is made of wear-resistant rubber and has anti-slip textures on the wheel rim, which not only facilitates smooth movement of the trolley on flat ground but also enhances friction with the ladder steps when climbing. A fixing mechanism 3 is provided on the lower front side of the support frame 1. This fixing mechanism 3 is a key component ensuring the stability of the trolley when carrying the corresponding frame. Its components cooperate with each other to achieve a firm fixation of the corresponding frame.

[0019] Reference Figure 2 , Figure 4 and Figure 5The fixing mechanism 3 includes a support plate 301 hinged to the lower front side of the support frame 1. The support plate 301 is connected to the support frame 1 via a hinge, allowing the support plate 301 to rotate 90 degrees around the hinge point. A guide post 302 is fixedly connected to the inner side wall of the support plate 301. Two sets of guide posts 302 are provided. A clamping plate 303 is slidably connected to the outer arc surface of the guide post 302. The clamping plate 303 can slide freely along the axial direction of the guide post 302. Adjusting the clamping plate 303 with respect to the support frame 1 is possible. The relative positions of other components of the pallet 301 are adjusted to accommodate items of different sizes. A threaded sleeve 310 is fixedly connected to the inner rear side of the pallet 301. A threaded rod 304 is threadedly connected to the inner wall of the threaded sleeve 310. The threaded sleeve 310 is fixed by welding, and its internal thread has high precision. The outer surface of the threaded rod 304 is machined with uniform external threads. By rotating the threaded rod 304, its axial movement within the threaded sleeve 310 can be achieved. The front part of the threaded rod 304 is cylindrical. The clamping plate 303 is designed for easy rotational connection with other components. A rotating plate 305 is rotatably connected to the inner wall of the clamping plate 303. Two sets of connecting plates 309 are hinged to the rear of the rotating plate 305. Each set of connecting plates 309 has a pressure plate 307 hinged to its side away from the rotating plate 305. Rotating the rotating plate 305 causes the two sets of connecting plates 309 to rotate, thereby causing the two sets of pressure plates 307 to move closer together or open. A mounting plate 311 is fixedly connected to the rear of the clamping plate 303. The top of the mounting plate 311... The support slot is provided in the part, and the front part of the clamping plate 303 is provided with a limiting component 308. The limiting component 308 can limit and fix the rotating plate 305. The rear part of the mounting plate 311 is fixedly connected with a contact plate 306. The two move along the same trajectory. The upper part of the tray 301 is provided with a positioning component 4. The positioning component 4 can fix the tray 301 in the storage state. The upper part of the tray 301 contacts a storage basket 5, which can hold some fire-fighting tools.

[0020] Reference Figure 6The limiting component 308 includes a limiting block 3081 fixedly connected to the front of the clamping plate 303. The inner wall of the limiting block 3081 has a cavity. A limiting post 3082 is elastically connected to the inner wall of the limiting block 3081 via a connecting spring 3083. The elasticity of the connecting spring 3083 allows the limiting post 3082 to have both resetting and limiting functions. The outer wall of the limiting post 3082 penetrates and is slidably connected to the inner wall of the limiting block 3081. The contact area between the limiting post 3082 and the limiting block 3081 is precision-machined to ensure proper limiting. The column 3082 can slide smoothly up and down, and is designed to allow for easy manual pulling of the limiting column 3082 to release the limiting function. The front of the rotating plate 305 has multiple sets of positioning holes, which are evenly distributed along the circumference of the rotating plate 305. The corresponding positioning hole can be selected according to the different angles that the rotating plate 305 needs to be fixed. The bottom end of the limiting column 3082 is inserted into the inner wall of the positioning hole. Through the cooperation of the limiting column 3082 and the positioning hole, the rotating plate 305 can be firmly fixed at the current angle to prevent it from rotating.

[0021] Reference Figures 3-4 The outer arc surface of the front part of the threaded rod 304 is rotatably connected to the inner wall of the clamping plate 303. The rotation setting can drive the clamping plate 303 to move, thereby fixing the storage basket 5. The front part of the support plate 301 has a through hole that matches the outer arc surface of the front part of the threaded rod 304. The outer arc surface of the front part of the threaded rod 304 contacts the inner wall of the through hole. The through hole setting does not affect the normal movement of the threaded rod 304.

[0022] Reference Figures 3-5 The rear protrusion of the pressure plate 307 contacts the upper inner side of the mounting plate 311, and the top of the pressure plate 307 contacts the top inner side of the clamping plate 303. The contact setting can guide the pressure plate 307. The outer wall of the mounting plate 311 has a round hole that matches the guide post 302. The round hole setting avoids movement interference. The rear end of the contact plate 306 contacts the bottom of the storage basket 5. The contact setting prevents the storage basket 5 from moving back and forth. A support beam is provided in the middle of the storage basket 5. The upper protrusion of the pressure plate 307 contacts the support beam. The contact setting prevents the storage basket 5 from moving horizontally.

[0023] Reference Figures 1-2 The positioning component 4 includes a magnetic block 401 fixedly connected to the upper part of the tray 301. The magnetic block 401 is made of a strong magnetic material, and its magnetism is durable and not easy to fade. A magnetic plate 402 is fixedly connected to the front of the support frame 1. The magnetic plate 402 is also made of a strong magnetic material. Its surface is flat and smooth. Its relative position with the magnetic block 401 has been precisely calibrated. The magnetic sides of the magnetic block 401 and the magnetic plate 402 that are close to each other have opposite magnetism. Utilizing the principle of attraction between opposite magnetic poles, when the tray 301 is stored, the magnetic block 401 and the magnetic plate 402 can be tightly attracted together, thereby achieving quick fixation of the tray 301.

[0024] Working principle: In use, by separating the magnetic block 401 and the magnetic plate 402 in the positioning component 4, the tray 301 is rotated from the storage state to a horizontal state around the hinge point. Then, the storage basket 5 containing fire-fighting tools is placed on the tray 301. Next, the threaded rod 304 is rotated to move it within the threaded sleeve 310, thereby causing the clamping plate 303 to slide along the guide post 302, allowing the contact plate 306 to contact the bottom of the storage basket 5 to restrict its forward and backward movement. Then, the limiting post 3082 of the limiting component 308 is pulled, causing the connecting spring 3083 to compress and release the limitation on the rotating plate 305. Rotating the rotating plate 305 drives the two sets of connecting plates 309 to move, causing the two sets of connecting plates 309 to move. The pressure plates 307 are brought closer together until the upper protrusion of the pressure plate 307 contacts the support beam in the middle of the storage basket 5 to restrict its lateral movement. Then the limiting post 3082 is released, allowing it to be inserted into the corresponding positioning hole of the rotating plate 305 under the action of the connecting spring 3083 to complete the fixation. At this time, the components of the fixing mechanism 3 cooperate to achieve a firm fixation of the storage basket 5. The ladder wheel 2 on the lower rear side of the support frame 1, with its wear-resistant rubber material and anti-slip texture, not only facilitates the movement of the trolley on flat ground, but also enhances the friction with the ladder steps when climbing, achieving a dual function of high and flat. When storing, the reverse operation resets the tray 301, and the fixation is completed by the attraction between the magnetic block 401 and the magnetic plate 402.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
