Description

Technical Field

[0001] This utility model belongs to the field of medical flatbed cart technology, and relates to a transport flatbed cart, and more particularly to a rainproof transport flatbed cart. Background Technology

[0002] Currently, medical stretchers and trolleys are generally used together. When an ambulance brings a patient to the hospital, the stretcher is placed directly onto the stretcher, and the stretcher is pushed around the hospital. Neither the existing stretchers nor the stretchers are equipped with protective covers. In inclement weather, patients transported by stretchers between hospital departments are easily exposed to wind and rain, resulting in a poor experience. Therefore, fixed protective curtains have been installed on stretchers or stretchers. However, the installation of such curtains makes ordinary stretchers or stretchers cumbersome and bulky, which is not very suitable for normal weather conditions. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a rainproof transport flatcar. It solves the technical problem of poor adaptability of existing flatcars.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A rainproof transport flatcar includes a flatcar, a stretcher, and a rain cover. The flatcar has a crossbeam along its length. The rain cover includes an aluminum alloy frame and a canopy. The outline of the aluminum alloy frame is similar to that of the flatcar and can be stacked on the flatcar. The aluminum alloy frame has a transverse limiting rod along its length. The transverse limiting rod and the crossbeam are spaced apart, forming a limiting space between them. The bottom of the stretcher has an abutment for contacting the ground. When the stretcher, rain cover, and flatcar are stacked sequentially from top to bottom, the abutment is located in the limiting space, and both sides of the abutment abut against the transverse limiting rod and the crossbeam, respectively.

[0006] The flatbed cart of this application consists of three independent parts: the flatbed cart, the stretcher, and the rain cover. The rain cover is separately installed and can be quickly attached and detached from the flatbed cart and the stretcher. It can be quickly installed when needed and quickly removed when not needed, allowing the flatbed cart to be selected whether to install the rain cover according to actual needs, thus greatly improving its adaptability.

[0007] The specific quick-assembly and disassembly structure is achieved through a crossbeam located on the flatbed and a lateral limiting rod located on the rain cover. The rain cover itself is fixed to the aluminum alloy frame. When needed, the aluminum alloy frame is simply lifted and placed on the flatbed, creating a gap between the lateral limiting rod and the crossbeam, i.e., the aforementioned limiting space. When the stretcher is placed on the flatbed, the abutment at the bottom of the stretcher will engage between the lateral limiting rod and the crossbeam to create a limit. The abutment acts like a pin, preventing the rain cover from moving laterally. The rain cover, stretcher, and flatbed form a whole. When the stretcher is removed, the limit between the rain cover and the flatbed is released, and the rain cover can be removed normally. This design allows the rain cover to be used according to needs, greatly improving its adaptability.

[0008] In the aforementioned rainproof transport flatcar, the maximum width of the abutment is the same as the distance between the transverse limiting bar and the crossbeam.

[0009] The abutment part of this application can both contact the ground and act as a limiting pin. The width of the abutment part is the same as the distance between the transverse limiting rod and the crossbeam, which allows the abutment part to be inserted between the two and firmly hold them together, locking the aluminum alloy frame and the flatcar firmly into a whole. The structure is stable and has high strength, and it enables rapid assembly and improves adaptability.

[0010] In the aforementioned rainproof transport flatcar, the abutment is U-shaped and has abutment at the bottom of both ends of the stretcher along its length.

[0011] The U-shaped abutment of this application allows for smoother insertion between the abutment and the transverse limiting rod and the crossbeam. The curved chamfer at the front end plays a good guiding role, ensuring smooth entry of the abutment and positioning the rain cover. It can also push the rain cover to be in the correct position, further improving its adaptability.

[0012] In the aforementioned rainproof transport flatcar, the flatcar includes a frame and outriggers with casters. Crossbeams are fixed at both ends of the frame along its length. The outline of the aluminum alloy frame is the same as that of the frame, and two transverse limiting rods are provided corresponding to the crossbeams.

[0013] The flatbed carriage of this application has two pairs of crossbeams and transverse limiting rods. Such limiting structures are set at both ends of the flatbed carriage in the length direction. In conjunction with the four abutment parts that are generally equipped at the bottom of the stretcher, they are inserted into the corresponding limiting structures in pairs. This allows the flatbed carriage, rain cover and stretcher to form a whole after the stretcher is put in, with strong structural stability and quick disassembly, which greatly meets the adaptability requirements.

[0014] In the aforementioned rainproof transport flatcar, both of the aforementioned transverse limiting rods are located on the outside of the corresponding crossbeams.

[0015] The lateral limiting rods of this application are all located on the outside of the crossbeam. This design ensures that after the abutment part is inserted, the lateral limiting rods on opposite sides are subjected to opposing forces, thereby allowing the rain cover to be stably fixed on the flatcar and the connection strength to be better.

[0016] In the aforementioned rainproof transport flatcar, the aluminum alloy frame includes two parallel guide rails. The transverse limiting rod is located between the two guide rails and its two ends are welded and fixed to the sides of the two guide rails respectively. Each guide rail has several sliders. The outer edges of the two sides of the cover are evenly fixed to the sliders of the guide rails. The cover is raised and lowered by sliding the sliders.

[0017] The rain cover of this application has a slidable hood that is attached to the aluminum alloy frame. This design allows for easy sliding and storage as needed, enabling the flatbed cart to move in various scenarios and further improving its adaptability.

[0018] In the aforementioned rainproof transport flatcar, the cover has ribs spaced apart along its length, and the two ends of the ribs are respectively fixed to two corresponding sliders on two guide rails.

[0019] The canopy in this application is also equipped with support bones, which allow the canopy to maintain its curved structure to support and cover the stretcher, providing the user with a more comfortable space.

[0020] In the aforementioned rainproof transport flatcar, the supporting frame has an arc-shaped structure.

[0021] In the aforementioned rainproof transport flatcar, the cover has flexible reinforcing strips on both sides of its width direction, and the flexible reinforcing strips are arranged along the length direction of the cover.

[0022] The edge of the screen in this application is provided with a flexible reinforcing strip. The flexible reinforcing strip will not affect the folding and storage of the screen. The flexible reinforcing strip at the edge can effectively increase the number of times the screen can be folded, prevent the edge of the screen from cracking due to folding, and improve the service life of the screen.

[0023] In the aforementioned rainproof transport flatcar, at least one end of the guide rail is provided with a hook, which is elastically connected to the guide rail.

[0024] Compared with the prior art, the advantages of this product are as follows: The flatbed of this application consists of three independent parts, namely the flatbed, the stretcher and the rain cover. The rain cover is set separately and can be quickly installed and disassembled with the flatbed and the stretcher. It can be quickly installed when needed and quickly disassembled when not needed, so that the flatbed can be selected whether to install the rain cover according to actual needs, which greatly improves its adaptability.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figures 1-3 The illustrated rainproof transport flatcar includes a flatcar 1, a stretcher 2, and a rain cover 3. The flatcar 1 has a crossbeam 13 along its length. The rain cover 3 includes an aluminum alloy frame 31 and a canopy 32. The canopy 32 is made of PVC or PE material and is transparent, flexible, and foldable. The aluminum alloy frame 31 has a similar outline to the flatcar 1 and can be stacked on the flatcar 1. The aluminum alloy frame 31 has a transverse limiting bar 33 along its length. The limiting bar and the crossbeam 13 are spaced apart, forming a limiting space 34 between them. The bottom of the stretcher 2 has an abutment part 21 for contacting the ground. When the stretcher 2, the rain cover 3, and the flatcar 1 are stacked from top to bottom, the abutment part 21 is located in the limiting space 34, and the two sides of the abutment part 21 abut against the transverse limiting bar 33 and the crossbeam 13, respectively. The flatbed cart 1 of this application consists of three independent parts, namely the flatbed cart 1, the stretcher 2, and the rain cover 3. The rain cover 3 is set separately and can be quickly installed and disassembled to connect with the flatbed cart 1 and the stretcher 2. It can be quickly installed when needed and quickly disassembled when not needed, so that the flatbed cart 1 can choose whether to install the rain cover 3 according to actual needs, thus greatly improving its adaptability.

[0031] The specific quick-assembly and disassembly structure is achieved through the crossbeam 13 located on the flatbed 1 and the transverse limiting rod 33 located on the rain cover 3. The rain cover 3's own canopy 32 is fixed to the aluminum alloy frame 31. When needed, the aluminum alloy frame 31 is directly lifted and placed on the flatbed 1. A gap, namely the aforementioned limiting space 34, will be formed between the transverse limiting rod 33 and the crossbeam 13. When the stretcher 2 is placed on the flatbed 1, the abutment part 21 at the bottom of the stretcher 2 will be inserted between the transverse limiting rod 33 and the crossbeam 13 to form a limit. The abutment part 21 acts like a pin to prevent the rain cover 3 from moving sideways. The rain cover 3, the stretcher 2, and the flatbed 1 form a whole. When the stretcher 2 is removed, the limit between the rain cover 3 and the flatbed 1 is released, and the rain cover 3 can be removed normally. This design allows the rain cover 3 to be used according to needs, greatly improving its adaptability.

[0032] Furthermore, the maximum width of the abutment part 21 is the same as the distance between the transverse limiting rod 33 and the crossbeam 13. The abutment part 21 of this application can both contact the ground and act as a limiting pin. The fact that the width of the abutment part 21 is the same as the distance between the transverse limiting rod 33 and the crossbeam 13 allows the abutment part 21 to be inserted between them and firmly hold them together, locking the aluminum alloy frame 31 and the stretcher 1 into a unified structure. This results in a stable and high-strength structure, enabling rapid assembly and improved adaptability. Preferably, the abutment part 21 is U-shaped, with abutment parts 21 at the bottom of both ends along the length of the stretcher 2. The U-shaped abutment part 21 of this application allows for smoother insertion between the transverse limiting rod 33 and the crossbeam 13. The chamfered front end provides excellent guidance, ensuring smooth entry of the abutment part 21 and also positioning the rain cover 3, pushing it to a correct position, further enhancing adaptability.

[0033] The specific structure of the flatbed 1 is as follows: The flatbed 1 includes a frame 11 and outriggers 12 with casters. The frame 11 has a square outline, and crossbeams 13 are fixed at both ends along the length of the frame 11. The outriggers 12 are installed at the bottom of the crossbeams 13. The crossbeams 13 serve both as supports and, in conjunction with the transverse limiting rods 33, limit the rain cover 3. The aluminum alloy frame 31 has the same outline as the frame 11, and two transverse limiting rods 33 are provided corresponding to the crossbeams 13. The flatbed 1 of this application has two pairs of crossbeams 13 and transverse limiting rods 33. Such limiting structures are provided at both ends along the length of the flatbed 1. In conjunction with the stretcher 2, which is generally equipped with four abutment parts 21 at the bottom, these parts are inserted into the corresponding limiting structures in pairs. This ensures that after the stretcher 2 is placed, the flatbed 1, rain cover 3, and stretcher 2 can form a whole, with strong structural stability and quick disassembly, thus meeting excellent adaptability. Furthermore, both lateral limiting rods 33 are located on the outer side of the corresponding crossbeam 13. The lateral limiting rods 33 of this application are all located on the outer side of the crossbeam 13. This design ensures that after the abutment part 21 is inserted, the opposing lateral limiting rods 33 on opposite sides resist each other's forces, thereby allowing the rain cover 3 to be stably fixed on the flatcar 1, resulting in better connection strength.

[0034] The specific structure of the rain cover 3 is as follows: The aluminum alloy frame 31 includes two parallel guide rails 35. A transverse limiting rod 33 is located between the two guide rails 35 and its two ends are welded and fixed to the sides of the two guide rails 35 respectively. Each guide rail 35 has several sliders 36. The outer edges of both sides of the rain cover 32 are evenly fixed to the sliders 36 of the guide rails 35. The rain cover 32 is opened and closed by sliding the sliders 36. The rain cover 32 of this application can be slidably connected to the aluminum alloy frame 31. This design allows for sliding and storage as needed, enabling the flatbed 1 to move in multiple scenarios and further improving its adaptability. Furthermore, the rain cover 32 has support bones 4 arranged at intervals along its length. The two ends of the support bones 4 are fixed to two corresponding sliders 36 on the two guide rails 35 respectively. The rain cover 32 of this application is also equipped with support bones 4. The support bones 4 allow the rain cover 32 to maintain an arc-shaped structure to support and cover the stretcher 2, providing the user with a better comfortable space. Furthermore, the support rib 4 has an arc-shaped structure. Furthermore, the cover 32 has flexible reinforcing strips 5 along its two sides in the width direction, arranged along the length direction of the cover 32. The material of the flexible reinforcing strips 5 is preferably linen or rubber. The flexible reinforcing strips 5 along the edges of the cover 32 in this application do not affect the folding and storage of the cover 32. The flexible reinforcing strips 5 effectively increase the number of folds of the cover 32 at the edges, preventing cracking of the edges due to folding and extending the service life of the cover 32. Furthermore, at least one end of the guide rail 35 is provided with a hook, which is elastically connected to the guide rail 35. A spring is connected to the hook, and one end of the spring is fixed to the guide rail 35. When the rain cover 3 is folded, the spring can be stretched to hook the hook onto the outermost slider 36, keeping the rain cover 3 in a folded state, thus improving adaptability.
