[0002] Hand-held pumps are crucial equipment for emergency operations such as firefighting and flood drainage, often requiring rapid transport to the work site. Traditional transportation methods typically involve manual handling or simple trolleys, which are inconvenient and inefficient. Particularly during the transport of hoses and other supporting equipment, the lack of dedicated storage structures often results in hoses being scattered and piled up haphazardly, impacting transport efficiency and potentially causing damage or tangling. While some existing transport devices are equipped with racks, their fixed structures prevent folding and storage, leading to significant space requirements during storage and transport. Furthermore, the hose storage area lacks expandable design, making it difficult to adapt to different operational scenarios. In addition, traditional devices lack stability, making them prone to tipping over during movement or operation, compromising safety. Therefore, there is an urgent need for a hand-held pump transport device that combines portability, storage capacity, and functional expandability to address the problems of low transport efficiency, poor space utilization, and insufficient adaptability in existing technologies.

Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] The following is for reference. Figures 1-5A portable hand-held pump transport device is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0029] like Figures 1-3 As shown, this application proposes a portable hand-held pump transport device, including a base frame 100, a movable frame 120, and a telescopic frame 140. The top surface of the base frame 100 is used to hold the hand-held pump, and wheels 110 are provided at the bottom. Two movable frames 120 are provided, hinged to both sides of the top surface of the base frame 100. Fixing components for securing the movable frames 120 are provided on both sides of the top surface of the base frame 100. A foldable and unfoldable shelf 130 is provided on the top of the movable frame 120, which is used to hold water hoses when unfolded. The telescopic frame 140 is telescopically mounted at the front and rear ends of the base frame 100, and is used to hold water hoses when extended. This technical solution solves the problems of poor space utilization and limited functionality of traditional transport devices by setting up the foldable movable frame 120 and the telescopic frame 140. The base frame 100 provides a stable support platform, and the movable frame 120 can be unfolded or folded as needed, facilitating the storage and retrieval of water hoses. The telescopic frame 140 can adjust its length according to the number of water hoses, adapting to different operational needs. Compared with existing technologies, this device has the advantages of compact structure, convenient operation, and strong functional expandability, which effectively improves the transportation efficiency of hand-operated pumps and supporting equipment.

[0030] Furthermore, such as Figure 4 and Figure 5 As shown, the base frame 100 has two hinge seats 150 on both the front and rear sides of its top surface. The movable frame 120 is inverted U-shaped, with both ends hinged to the hinge seats 150. Specifically, the hinge seats 150 can be made of metal casting or welding, and their installation positions are determined by structural strength calculations to ensure they can withstand the load when the movable frame 120 is unfolded. The inverted U-shaped movable frame 120 can be made of bent steel pipe with hinge holes machined at both ends, and is rotatably connected to the hinge seats 150 via pins. As a preferred embodiment, the wall thickness of the movable frame 120 pipe is not less than 2mm to ensure structural rigidity. Furthermore, the spacing of the hinge seats 150 is optimized to match the width of a standard hose reel, allowing the unfolded shelf 130 to stably support the hose. Thus, this technical solution achieves stable hinged connection and reliable support for the movable frame 120 through the cooperation of the symmetrically distributed hinge seats 150 and the inverted U-shaped movable frame 120. Among them, the double hinged seat 150 design effectively distributes the load and avoids the structural risks of single-point support; the inverted U-shaped structure reduces the overall weight while ensuring strength.

[0031] Furthermore, this application proposes that the hinge seat 150 is provided with a hinge groove 160, and the movable frame 120 is provided with a hinge shaft 170 that is hinged to both sides of the hinge groove 160. The fixing components include a baffle 180 and a stop bar 190 disposed in the hinge groove 160. The baffle 180 is disposed below the hinge shaft 170 near the inner side of the base frame 100, and the stop bar 190 is movably disposed below the hinge shaft 170 near the outer side of the base frame 100. Specifically, the hinge groove 160 is a U-shaped or semi-circular groove structure used to accommodate the hinge shaft 170 and limit its radial displacement. The height of the baffle 180 is lower than the center line of the hinge shaft 170, used to prevent the movable frame 120 from tilting inward. The stop bar 190 is a cylindrical metal rod that moves vertically through the lifting slide 200, and the return spring 210 is a helical spring. Thus, this technical solution effectively solves the stability problem of the movable frame 120 in the unfolded state through the dual limiting design of the baffle 180 and the stop bar 190. When the movable frame 120 unfolds outward, the stop bar 190 automatically rises and locks the hinge shaft 170 under the action of the return spring 210; when folding is required, the stop bar 190 can be manually pressed down to release the lock. Compared with the traditional single fixed structure, this design ensures both ease of operation and avoids the frame from tipping over due to accidental collisions.

[0032] Furthermore, this application proposes that the hinge groove 160 has lifting slides 200 on both sides to accommodate the up-and-down movement of the stop rod 190, and the hinge seat 150 has a return spring 210 connected to the stop rod 190 on its outer side. Specifically, the lifting slide 200 is a vertical guide structure used to restrict the stop rod 190 to move only in the vertical direction. The stop rod 190 can be a cylindrical metal rod with a diameter slightly smaller than the width of the slide to ensure smooth sliding. One end of the return spring 210 is fixed to a spring seat on the outer side of the hinge seat 150, and the other end is connected to the end of the stop rod 190. When the stop rod 190 is pressed down, the spring is compressed and stores energy; after the pressure is released, the spring pushes the stop rod 190 to automatically return to its original position. In addition, a wear-resistant bushing can be added between the stop rod 190 and the lifting slide 200 to reduce wear caused by long-term use.

[0033] Therefore, this technical solution achieves the automatic reset function of the fixed component of the movable frame 120 through the synergistic action of the lifting slide 200 and the return spring 210. When the movable frame 120 needs to be unfolded, the stop bar 190 moves down along the slide bar under the downward pressure of the hinge shaft 170 of the movable frame 120, at which time the return spring 210 stores energy; when the movable frame 120 is folded up, the hinge shaft 170 is released from the pressure on the stop bar 190, the spring releases energy to push the stop bar 190 back to its initial position, and re-establishes the limit on the hinge shaft 170. This design effectively solves the cumbersome problem of traditional fixed components requiring manual operation, simplifies the device usage process, and ensures the stability of the movable frame 120 in the unfolded state through a mechanical self-locking structure. Compared with the existing technology that uses pins or bolts for fixing, this solution has the characteristics of convenient operation and high reliability, and is particularly suitable for operation scenarios that require frequent unfolding / folding.

[0034] Furthermore, such as Figure 4 As shown, the two hinge seats 150 located on one side share the same stop bar 190. Specifically, the stop bar 190 adopts a transverse through-type design, passing through the lifting grooves 200 of both hinge seats 150. As a preferred embodiment, the stop bar 190 can be a solid metal rod with limiting protrusions at both ends that cooperate with the lifting grooves 200. Thus, when the stop bar 190 is subjected to external force, it can achieve synchronous lifting and lowering movement on both sides. This technical solution achieves the linkage control of the fixing components of the two hinge seats 150 through the design of the shared stop bar 190. The specific working principle is as follows: when it is necessary to fix the movable frame 120, only one side stop bar 190 needs to be operated to complete the fixing of both sides at the same time, avoiding the cumbersome operation of separate operations. Compared with the prior art, this design simplifies the operation steps and improves the ease of use of the device; at the same time, it reduces the number of parts, reduces manufacturing costs and maintenance difficulty. In terms of structural stability, the shared stop bar 190 ensures the synchronicity of the fixing components on both sides, effectively preventing the device from shaking due to incomplete fixing on one side.

[0035] Furthermore, this application also proposes that the height of one hinge seat 150 is higher than the height of the other hinge seat 150. Specifically, the height difference design of the hinge seats 150 ensures that the two movable frames 120 are flat on both sides when folded, which is beneficial for transportation. Figure 3 As shown.

[0036] Furthermore, this application proposes that the telescopic frame 140 is U-shaped, and the base frame 100 has telescopic channels (not shown in the figure) at both its front and rear ends to accommodate the telescopic frame 140. The telescopic channels have multiple circular locking holes 220 along their length, and the telescopic frame 140 has ball-loaded buckles 230 that engage with the circular locking holes 220. Specifically, the U-shaped design of the telescopic frame 140 allows it to form a stable mating structure with the base frame 100, facilitating the suspension and placement of the hose. The telescopic channels allow the telescopic frame 140 to be length-adjusted according to actual needs, and the engagement of the circular locking holes 220 and the ball-loaded buckles 230 enables multi-position fixing of the telescopic frame 140. As a preferred embodiment, the ball-loaded buckles 230 can be made of spring-loaded steel balls, unlocked by pressing, which is simple to operate and highly reliable. Thus, this technical solution, through its telescopic U-shaped frame structure, effectively solves the problem that traditional transport devices cannot flexibly expand the hose placement area. When stored, the telescopic frame 140 can be completely retracted into the base frame 100, reducing space occupation; during operation, it can be pulled out and fixed at different length positions, providing ample hanging space for the water hose. Compared with the fixed shelf 130, this design significantly improves the space utilization and flexibility of the device, while the mechanical buckle structure ensures the stability of the telescopic frame 140 during transportation and operation.

[0037] Furthermore, this application proposes that the shelf 130 is hinged to the movable frame 120 via an angle steel 240. When the shelf 130 is unfolded outwards from the base frame 100, it is fixed; when folded inwards from the base frame 100, the shelf 130 is folded inwards. The angle steel 240, as a connector, provides stable hinge support due to its L-shaped cross-section. In a specific implementation, one side of the angle steel 240 is fixedly connected to the top of the movable frame 120 via bolts, and the other side is hinged to the frame of the shelf 130. In the unfolded state, the shelf 130 is fixed at a 90-degree angle to the movable frame 120 by gravity; when folded, the shelf 130 rotates inwards around the hinge axis 170 until it is parallel and flush with the movable frame 120.

[0038] Furthermore, this application proposes that wheel 110 is a swivel wheel, and the swivel wheel is equipped with a locking mechanism (the locking mechanism is prior art and is not shown in the figure). The swivel wheel is an industrial-grade swivel wheel with a braking function, and the wheel body is made of polyurethane-coated nylon, which has wear-resistant and quiet characteristics. The locking mechanism adopts a foot-operated braking device, which drives the brake block to contact the wheel surface to achieve locking by stepping on the brake pedal. As another embodiment, the locking mechanism can adopt a knob-type brake, which drives the gear mechanism to press the wheel axle to achieve fixation by rotating the handle. When the swivel wheel is installed, it is connected to the base frame 100 by bolt fixing, and shock-absorbing rubber pads are provided at the connection between the wheel frame and the base frame 100. This technical solution solves the problem of traditional transportation devices easily sliding on slopes or uneven ground by adopting a swivel wheel structure with a locking function. When the device needs to be fixed for operation, the locking mechanism can quickly brake wheel 110 to prevent the device from moving accidentally; during transportation, the flexible steering characteristics of the swivel wheel can improve the device's passability in narrow spaces. Compared to the fixed wheels 110, this design ensures both ease of movement and operational stability, effectively improving the safety and ease of use of the device. Specifically, the polyurethane wheel surface reduces noise while enhancing grip, and the dual braking system allows for selection of the most suitable locking solution based on different usage scenarios.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
