Description

Technical Field

[0001] This utility model belongs to the technical field of medical stretcher trolley equipment, specifically a mobile stretcher trolley with a swing frame. Background Technology

[0002] In emergency department clinical practice, it is necessary to quickly and stably transport patients to designated treatment areas at any time. Currently, the most convenient and safest option is a mobile stretcher trolley. A stretcher trolley consists of a bed frame with a mattress on it for the patient to lie down. The bed frame is equipped with casters for easy movement.

[0003] In the existing technology, when a patient is on a stretcher, some special circumstances require intravenous infusion during the transfer process. However, most existing stretchers do not have a structure for hanging infusion bottles, which means that medical staff usually have to stand directly next to the stretcher, holding the infusion bottle high, which is inconvenient to use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mobile stretcher pusher with a swing frame.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A mobile stretcher gurney with a swing frame, comprising:

[0007] A bed frame, with a bed board installed at the upper end of the bed frame, and an installation box fixedly installed between the bed frames directly below the bed board. A threaded rod is installed in the installation box, and the threaded rod is rotatably connected to the bed frame. One end of the threaded rod is fixedly connected to the output shaft of a drive motor, and the drive motor is fixedly installed on the side of the bed frame. Both sides of the installation box are provided with through slots, and both sides of the bed frame are provided with limit slots.

[0008] A first movable block is mounted on the side end of a threaded rod and is threadedly connected to the threaded rod. Support rods are fixedly mounted on both sides of the first movable block. The end of the support rod away from the first movable block passes through a limiting groove and is located on the side end of a support frame. A mounting plate is fixedly mounted on the end of the support rod away from the first movable block. Each mounting plate has a mounting groove on its side end. A swing frame assembly is mounted between two mounting plates via a pin. The swing frame assembly is rotatably connected to the mounting plate. A first through hole is opened on the side end of the swing frame assembly. Multiple first insertion holes are opened on the mounting plate around the mounting groove. The first insertion holes are adapted to the first through holes. A plug-in assembly is installed at the first through hole. The swing frame assembly is fixed to the mounting plate via the plug-in assembly.

[0009] Furthermore, the swing frame assembly includes two support plates, two vertical connecting rods, and a connecting rod. A vertical connecting rod is fixedly installed on the upper end of each support plate, and a connecting rod is fixedly installed between the two vertical connecting rods.

[0010] Furthermore, a movable groove is provided at the lower end of the connecting rod, and a plurality of second through holes are evenly provided at the side end of the connecting rod. A second movable block is installed in the movable groove, and a second insertion hole is provided at the side end of the second movable block. The second insertion hole is adapted to the second through hole. A plug-in assembly is fixedly installed at the side end of the second movable block. The second movable block is fixed to the connecting rod through the plug-in assembly. A hook is fixedly installed at the lower end of the second movable block.

[0011] Furthermore, the plug-in assembly includes a plug-in member, a connecting spring, and a connecting plate. When the plug-in assembly is installed on the side of the mounting plate, the connecting plate is fixedly connected to the mounting plate by two springs. The plug-in member is fixedly installed on the side of the connecting plate, and the end of the plug-in member away from the connecting plate protrudes from the mounting plate.

[0012] Furthermore, the bed frame has sliding grooves on both sides of the limiting groove, and a slider is fixedly installed on the side of the mounting plate, the slider being adapted to the sliding groove.

[0013] Furthermore, four support legs are fixedly installed at the lower end of the bed frame, and each support leg is equipped with a self-locking caster wheel at its lower end.

[0014] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0015] Fixed connection: refers to a connection in which parts or components are fixed in place and there is no relative movement. It is divided into two types: detachable connection and non-detachable connection.

[0016] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0017] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0018] The beneficial effects of this utility model are:

[0019] In this device, after the patient lies on the bed board, the swing frame assembly is used to suspend the IV drip. The drive motor controls the rotation of the threaded rod, which in turn moves the first moving block, thereby causing the swing frame assembly to move laterally. When the plug-in assembly is pulled out and the fixing between the swing frame assembly and the mounting plate is released, the swing frame assembly can be rotated downwards, so that the swing frame assembly is level with the bed frame, making it easier to lift the patient with limited mobility onto the bed board.
