[0002] Water sprinkler trucks, also known as spray trucks, multi-functional water sprinkler trucks, landscaping water sprinkler trucks, water tankers, water transport trucks, and washing trucks, are suitable for washing various road surfaces, watering trees, green belts, and lawns, as well as for road and factory construction and high-rise building washing.

[0003] A water sprinkler truck mainly consists of a chassis, water tank, power take-off (PTO), water pump, piping system, and rear work platform. The rear work platform is a standard feature of water sprinkler trucks, installed at the very back, behind the tank. Its main components include the platform, guardrails, rear spray pipes, and a high-mounted water cannon. Work on the rear platform is usually done outdoors, making it susceptible to direct sunlight in summer or sudden inclement weather, resulting in a harsh working environment and insufficient protection for operators.

[0004] A search revealed that Chinese utility model patent CN213596909U discloses a high-safety rear work platform for a sprinkler truck, including a vehicle body. A water tank is fixedly connected to the top surface of the vehicle body, and a spray pipe is fixedly connected to the right side of the top surface of the water tank. A connecting pipe is fixedly connected to the end of the spray pipe away from the water tank, and a nozzle is fixedly connected to the end of the connecting pipe away from the spray pipe. A work platform is fixedly connected to the right side of the vehicle body, and a guardrail is fixedly connected to the top surface of the work platform. A fixing block is fixedly connected to the right side of the guardrail. This application provides protection for operators on the rear platform by installing a sunshade. However, since the sunshade is fixedly installed, it may pose a safety hazard in situations such as tunnels, garages, or under trees or under utility tunnels, leading to inconvenience in operation. Utility Model Content

[0005] In view of the above-mentioned prior art, the present invention provides a rear working platform for a water sprinkler truck, and the main technical problem to be solved is how to ensure that the protective measures on the rear platform do not affect the operation convenience of the water sprinkler truck.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows: A rear working platform for a water sprinkler truck includes a rear platform of the water sprinkler truck. The rear platform includes a platform surface and a guardrail fixedly installed on the platform surface. The guardrail is provided with a frame mechanism and a sunshade for personnel protection. The frame mechanism includes several support plates. The sunshade is installed outside the support plates. The several support plates fold and extend the sunshade by deflection.

[0007] Furthermore, side plates are fixedly connected to both sides of the top of the guardrail, and threaded through holes are opened at the top of the two side plates. Threaded rods are threadedly connected to the threaded through holes of the two side plates.

[0008] Furthermore, a turntable is fixedly connected to the ends of the two threaded rods that are close to each other, and a baffle is fixedly connected to the ends of the two threaded rods that are far apart from each other.

[0009] Furthermore, several support plates are evenly distributed on the outside of the two threaded rods, and a bearing is installed through the bottom end of the support plate, with the bearing sleeved on the outside of the threaded rod.

[0010] Furthermore, the number of support plates located on the outside of the two threaded rods is the same and they correspond one-to-one, and a connecting rod is fixedly connected at the top of the two corresponding support plates on the left and right sides.

[0011] Furthermore, the top of each of the two side plates, which are close to each other, is fixedly connected to a stop block on both sides of the support plate.

[0012] Furthermore, threaded grooves are provided at the top outer side of the support plate, and bolts are threadedly connected to the support plate at the threaded grooves.

[0013] Furthermore, the bottom of the sunshade is equipped with several hanging rings that are compatible with the bolts.

[0014] Furthermore, a spring buckle that matches the lifting ring is fixedly connected to the top of the connecting rod.

[0015] The beneficial effects of this utility model are as follows: 1. This application uses several foldable support plates to install the sunshade. Therefore, the sunshade can be unfolded by the support plates to provide protection for personnel on the rear platform. In situations with height restrictions or where sunshade is not required, the sunshade can be stored by folding the support plates to ensure the convenience of the sprinkler truck's operation. 2. By setting bolts and lifting rings, the bolts can lock the lifting rings to fix the sunshade on the support plate. Therefore, the sunshade can be removed by removing the bolts. So when the sunshade is used for a long time and repeatedly and develops creases or damage, it can be easily cleaned, maintained or replaced to ensure that the device can play a long-term and effective protective role. 3. By using spring clips to further connect the sunshade, its stability during use after installation can be maintained to a greater extent, reducing the possibility of the sunshade falling off due to wind, scratches or collisions.

[0018] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the utility model.

[0019] Example 1 See attached document Figure 1-2 This application provides a rear working platform for a water sprinkler truck, including a rear platform 1. The rear platform 1 includes a platform 101 and a guardrail 102 fixedly mounted on the platform 101. The guardrail 102 is provided with a frame mechanism and a sunshade 6 for personnel protection. The frame mechanism includes several support plates 5. The sunshade 6 is detachably mounted on the outside of the support plates 5. The several support plates 5 are deflected to fold and extend the sunshade 6. The arrangement of the several support plates 5 is similar to the ribs of a folding fan. The support plates 5 are long strips, so they can be stacked to achieve folding, so as to fold and extend the sunshade 6.

[0020] Preferably, side plates 2 are fixedly connected to both sides of the top of the guardrail 102. Each side plate 2 has a threaded through hole at its top, and a threaded rod 4 is threadedly connected to each of the two side plates 2 at the threaded through hole. Therefore, rotation of the threaded rod 4 allows it to move relative to the side plate 2, enabling the turntable 7 to press and clamp the support plate 5. The turntable 7 is fixedly connected to the ends of the two threaded rods 4 that are close to each other, and a baffle 3 is fixedly connected to the ends of the two threaded rods 4 that are far apart from each other. The baffle 3 limits the maximum distance the threaded rod 4 can move on the side plate 2, preventing excessive rotation of the threaded rod 4 from causing it to detach from the side plate 2.

[0021] Preferably, the top of each of the two side plates 2 that are close to each other is fixedly connected to a stop block 201 on both sides of the support plate 5. The space between the two stop blocks 201 is the maximum deflection range of the support plate 5. Therefore, by having the two support plates 5 at the beginning and end abut against different stop blocks 201 respectively, the minimum folded state and the maximum unfolded state of the support plate 5 can be limited, making the folding and unfolding process of the sunshade 6 more stable and preventing it from falling due to its own weight.

[0022] When personnel are on the rear platform 1 of the water truck, the turntable 7 can be rotated to make the threaded rod 4 rotate and retract, so that the support plates 5 are loose, thus the deflection of the support plates 5 can be adjusted within the range between the two stops 201 to achieve the folding and extension of the sunshade 6. Therefore, when the water truck faces direct sunlight in summer or sudden bad weather, the sunshade 6 can be extended to provide protection for the operators on the rear platform 1. When there are height restrictions or no need for sunshade, the sunshade 6 can be folded for storage to ensure the convenience of water truck operation. Preferably, a number of support plates 5 are evenly distributed on the outside of the two threaded rods 4. A bearing 501 is installed through the bottom of the support plate 5. The bearing 501 is sleeved on the outside of the threaded rod 4. The thickness of the bearing 501 is less than the thickness of the support plate 5. Therefore, when the rotation of the threaded rod 4 causes the turntable 7 to press the support plates 5 closer to each other, the two adjacent support plates 5 will not rotate relative to each other due to the presence of the bearing 501. Instead, the two adjacent support plates 5 will generate a large frictional force due to the pressing of the turntable 7, so that all the support plates 5 remain stable. The number of support plates 5 located on the outside of the two threaded rods 4 is the same and corresponds one-to-one. A connecting rod 8 is fixedly connected to the top of the two corresponding support plates 5 on the left and right sides. The connecting rod 8 is used to support the sunshade 6 and prevent it from collapsing towards the center.

[0023] After adjusting the support plate 5 to extend and fold the sunshade 6, it can be moved forward by rotating the threaded rod 4 in the opposite direction. Thus, the support plate 5 can be pressed by the turntable 7, so that the support plates 5 are locked together by mutual compression, thereby ensuring the stability of the sunshade 6 in the extended or folded state.

[0024] Preferably, threaded grooves are provided at the top outer side of the support plate 5, and bolts 502 are threadedly connected to the support plate 5 at the threaded grooves. The bottom of the sunshade 6 is provided with several lifting rings 601 that are compatible with the bolts 502. By placing the lifting rings 601 outside the bolts 502 and threading the bolts 502 to the support plate 5, the sunshade 6 can be installed on the support plate 5. Conversely, the sunshade 6 can also be disassembled.

[0025] When the sunshade 6 develops creases or damage due to long-term and repeated folding and use, the sunshade 6 can be removed by twisting the bolt 502, so that the sunshade 6 can be separated from the support plate 5. This allows for cleaning, maintenance or replacement of the sunshade 6, ensuring that the device can effectively protect the operator for a long time.

[0026] Example 2 See attached document Figure 3 This application provides a rear working platform for a sprinkler truck. Compared with embodiment 1, in order to further maintain the installation stability of the sunshade 6, the top end of the connecting rod 8 is fixedly connected with a spring buckle 801 that is compatible with the hanging ring 601.

[0027] By connecting the spring buckle 801 to the hanging ring 601 at the bottom center of the sunshade 6, the sunshade 6 can be further fixed to ensure its stable installation and reduce the possibility of the sunshade 6 falling off due to wind, scratches or collisions.

[0028] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model shall be determined by the protection scope of the claims.
