Description

Technical Field

[0001] The present invention belongs to the technical field of wheel locking devices, and in particular relates to a fixing device and a fixing method for wheeled medical equipment. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the medical field, wheeled medical equipment is widely used due to its mobility, such as hospital beds, monitor carts, and drug transport vehicles. When these devices are stationary, reliably securing their wheels is crucial to prevent them from sliding due to accidental collisions, ground slopes, or minor external forces, which could affect their normal use or even cause safety accidents.

[0004] Currently, most common wheel-mounted medical equipment uses brake-like structures to secure the wheels. These devices typically generate friction through contact between the brake components and the wheel surface, limiting wheel rotation. However, in practice, these traditional securing methods present two issues: First, they constrain the wheel in only a single direction, failing to fully restrict its movement. When the device is subjected to lateral forces or external impacts, the wheel may still slide against the floor, causing unexpected movement of the medical device. Second, some securing devices require complex operation, such as repeatedly turning multiple components, which consumes considerable medical staff time and limits the stability of the secured device. Summary of the Invention

[0005] In response to the above problems, the present invention provides a fixing device and fixing method for wheeled medical equipment, which solves the problem that traditional fixing methods are prone to sliding friction causing unexpected movement of medical equipment, and also solves the problem that the fixing device is complicated in the operation process.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions: In the first aspect, the present invention provides a fixing device for wheeled medical equipment, comprising: a locking seat, a positioning baffle and a locking baffle; the positioning baffle is arranged at one end of the locking seat, and the locking baffle is arranged at the other end of the locking seat; the locking seat is a horizontally arranged U-shaped structure, and a plurality of adjustment slots are provided at the open end, which are used to adjust the locking baffle according to different wheel sizes and install it in different adjustment slots, and the locking baffle can move up and down in the adjustment slot, and a plurality of limiting slots are provided on one side of the locking baffle, and a locking hole is provided above the adjustment slot, and a locking pin is inserted into the locking hole, and the locking pin realizes height adjustment and positioning of the locking baffle by penetrating into different limiting slots, thereby realizing fixation of wheels of different sizes.

[0007] As a further implementation method, the locking baffle is composed of a first vertical plate and a first inclined plate, a set angle is set between the first vertical plate and the first inclined plate, and the first inclined plate is fixedly connected to the top end of one side of the first vertical plate, so that the end surface of the top end of the first vertical plate can also contact the locking pin to achieve the positioning of the locking baffle.

[0008] As a further implementation, the limiting groove is provided on a side of the first vertical plate away from the first inclined plate, and a plurality of the limiting grooves are provided and are arranged horizontally.

[0009] As a further implementation method, the adjustment groove is arranged on the two inner sides of the locking seat opening, and the adjustment groove is arranged vertically for installing the first vertical plate. Multiple adjustment grooves are arranged in sequence along the horizontal direction of the side wall of the locking seat.

[0010] As a further implementation, a plurality of locking holes are provided, and are arranged in sequence along the horizontal direction of the side wall of the locking seat; each locking hole is provided corresponding to one of the adjustment slots.

[0011] As a further implementation method, the positioning baffle is composed of a second vertical plate and a second inclined plate; the second vertical plate and the second inclined plate are connected by welding, and a set angle is set between the second vertical plate and the second inclined plate, so that the second inclined plate can limit the wheel from jumping in the locking seat.

[0012] As a further implementation, a plurality of waist holes are provided on the second vertical plate, and a clamping device is provided in the waist holes for adjusting and fixing the relative position between the second vertical plate and the locking seat.

[0013] As a further implementation method, the clamping device includes a clamping handle, a clamping fixing block and a connecting threaded rod; one end of the connecting threaded rod passes through the waist hole and is threadedly engaged with the locking seat; the clamping fixing block is passed through the connecting threaded rod, and the other end of the connecting threaded rod is hinged to the clamping handle.

[0014] As a further implementation, the hinged joint between the clamping handle and the connecting threaded rod is a cam structure, and the clamping fixing block is clamped or loosened by the cam structure.

[0015] In a second aspect, the present invention further provides a method for fixing a fixing device of a wheeled medical device, comprising the following steps: S1. Based on the size of the wheel to be secured, insert the first vertical plate of the locking baffle into the appropriate adjustment slot to initially adjust the position in the wheel width direction. Move the locking baffle to an appropriate height so that the first vertical plate and the first inclined plate can fit the side of the wheel. Align the stop slot on the locking baffle with the locking hole above the adjustment slot. Insert the locking pin into the locking hole and allow it to penetrate the corresponding stop slot. S2. Adjust the relative position between the second vertical plate and the locking seat so that the positioning baffle can fit with the other side of the wheel, and use the multiple waist holes and clamping devices on the second vertical plate to fix it, rotate the connecting threaded rod to adjust the clamping and fixing block to just fit the second vertical plate, and rotate the clamping handle to use the cam structure to compress the clamping and fixing block, thereby fixing the position of the second vertical plate, so that the positioning baffle can firmly rest against the other side of the wheel.

[0016] Compared with the prior art, the present invention has the following advantages and positive effects: The locking seat of the present invention is securely fixed to the floor via a connector, providing a solid foundation for the entire fixing device. Positioning baffles and locking baffles are respectively disposed at each end of the locking seat, forming a clamping force for the wheel. The locking seat adopts a horizontal U-shaped structure with multiple adjustment slots at the open end, allowing the locking baffle's installation position to be flexibly adjusted according to the wheel size. The locking baffle can move up and down within the adjustment slots. Multiple limiting slots are provided on its side, cooperating with locking holes and locking pins above the adjustment slots to achieve precise height adjustment and positioning, effectively securing wheels of different sizes. Through the coordination between the locking seat, positioning baffles, and locking baffles, the fixing device achieves all-round positioning from both sides of the wheel and vertically, completely resolving the problem of wheel movement caused by sliding friction under traditional fixing methods. Compared to traditional wheel locking devices with brake-like structures, this device can prevent medical equipment movement caused by sliding friction between the wheel and the floor. Furthermore, the diverse installation positions of the adjustment slots significantly improve the adaptability and fixing stability of wheels of various sizes.

[0017] The locking seat of the present invention is fixed to the floor through a connecting piece, providing stable support for the entire fixing device, so that the wheel is not easily displaced as a whole due to external force after being fixed, thereby ensuring the safety of the wheeled medical equipment during use; the horizontal U-shaped structure and the multiple adjustment slots at the open end are designed to adjust the installation position of the locking baffle according to the wheel width, and can adapt to wheels of different sizes, greatly improving the versatility of the fixing device and reducing the cost and inconvenience of replacing the fixing device due to differences in equipment wheel specifications.

[0018] The locking baffle of the present invention is composed of a first vertical plate and a first inclined plate connected at a specific angle. The first inclined plate is connected to the top end of the first vertical plate, so that the top end face of the first vertical plate can be in close contact with the locking pin. Combined with the cooperation of the limiting groove and the locking pin, precise positioning in the height direction is achieved, ensuring that the baffle is closely fitted to the side of the wheel, thereby enhancing the fixing effect; by adjusting the locking pin and inserting it into different limiting grooves, the height of the locking baffle can be flexibly adjusted to closely fit the side of the wheel, effectively preventing the wheel from moving in the lateral direction, and avoiding the shaking of the wheel from affecting the normal use of medical equipment or causing safety hazards.

[0019] The second vertical plate and the second inclined plate of the positioning baffle of the present invention are welded to form a set angle, which can limit the jumping of the wheel in the locking seat from the other side, effectively solve the problem of vertical movement of the wheel, improve the stability of the wheel when it is fixed, and ensure the stability of the medical equipment in operation or at rest; the waist hole on the second vertical plate cooperates with the clamping device, and the relative position with the locking seat can be flexibly adjusted. No matter what size the wheel is, it can be tightly fitted and firmly fixed through this structure, further enhancing the adaptability of the device to different wheels.

[0020] The clamping device of the present invention adopts a clamping handle with a cam structure in cooperation with a connecting threaded rod and a clamping fixing block. The second vertical plate can be quickly tightened or loosened by simply turning the handle. Compared with the traditional complicated fixing method, the operation efficiency is greatly improved, and manpower and time costs are saved. The unique mechanical principle of the cam structure can make the clamping fixing block generate greater pressure, firmly fix the positioning baffle in the appropriate position, ensure the stable positioning of the positioning baffle on the wheel, avoid the loosening of the wheel due to loose fixation, and ensure that the medical equipment is fixed reliably.

[0024] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0025] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention.

By cooperating with the locking seat 1, the locking baffle 2 and the positioning baffle 3, an all-round limited fixation is formed from both sides of the wheel and in the vertical direction, which solves the problem that the wheel is easily displaced due to the single-direction fixation of the traditional fixing device. Specifically, the wheel is completely fixed by the locking seat 1. Since the locking seat 1 is fixed to the floor through the mounting block 4, the wheel is locked in the state of being wrapped by the locking seat 1, rather than the existing wheel locking device. The existing wheel locking device is mostly a brake-like structure, but there is still sliding friction between the wheel and the floor, which causes the medical equipment to move. In this embodiment, multiple adjustment slots 8 are provided for installation in different positions, so that the device can adapt to wheels of various sizes. At the same time, by adjusting the position and height of the locking baffle 2 and cooperating with the fixation of the positioning baffle 3, wheels of different sizes can be tightly wrapped, thereby improving the adaptability and fixing stability of the fixing device to wheeled medical equipment of various sizes.

[0026] As a further implementation method, the locking baffle 2 is composed of a first vertical plate and a first inclined plate, a set angle is set between the first vertical plate and the first inclined plate, and the first inclined plate is fixedly connected to the top of one side of the first vertical plate, so that the end surface of the top of the first vertical plate can also contact the locking pin 7, thereby realizing the positioning of the locking baffle 2; the locking baffle 2 adopts the first vertical plate and the first inclined plate to be connected at a specific angle, and the first inclined plate is fixed to the top of one side of the first vertical plate, so that the end surface of the top of the first vertical plate can be in close contact with the locking pin 7, thereby realizing completely reliable positioning of the locking baffle 2.

[0027] As a further implementation, the limiting slots 5 are located on the side of the first vertical plate away from the first inclined plate. Multiple limiting slots 5 are provided and arranged horizontally. The first vertical plate and the first inclined plate, combined with the limiting slots 5 and the locking pin 7, solve the problems of loose side wheel fixation and difficult height adjustment. By adjusting the locking pin 7 and inserting it into different limiting slots 5, the height of the locking baffle 2 can be precisely adjusted, ensuring that the baffle fits tightly against the side of the wheel, enhancing the fixing effect and preventing lateral wheel movement.

[0028] As a further implementation method, the adjustment groove 8 is provided on the two inner sides of the opening of the locking seat 1, and the adjustment groove 8 is arranged vertically for installing the first vertical plate. A plurality of the adjustment grooves 8 are arranged in sequence along the horizontal direction of the side wall of the locking seat 1; so that the fixing device can install the locking baffle 2 in the adapted adjustment groove 8 according to wheels of different sizes, so as to achieve a tight fit to the wheel, avoid a large gap between the wheel and the locking baffle 2, and cause the medical device to shake.

[0029] As a further implementation method, there are also multiple locking holes 6, which are arranged in sequence along the horizontal direction of the side wall of the locking seat 1; each locking hole 6 is arranged corresponding to one of the adjustment slots 8, and is used to cooperate with the locking baffle 2 to fix different wheels.

[0030] As a further implementation method, the positioning baffle 3 is composed of a second vertical plate and a second inclined plate; the second vertical plate and the second inclined plate are connected by welding, and a set angle is set between the second vertical plate and the second inclined plate, so that the second inclined plate can limit the wheel from bouncing in the locking seat 1; the second vertical plate and the second inclined plate are welded to form a set angle, which can limit the wheel from bouncing in the locking seat 1 from the other side, effectively solving the problem of vertical movement of the wheel, improving the stability of the wheel when it is fixed, and ensuring the stability of the medical equipment in operation or at rest.

[0031] As a further implementation method, a plurality of waist holes 9 are provided on the second vertical plate, and a clamping device is provided in the waist holes 9 for adjusting and fixing the relative position between the second vertical plate and the locking seat 1; the setting of the waist holes 9 and the clamping device realizes the flexible adjustment and firm fixation of the relative position of the positioning baffle 3 and the fixing seat.

[0032] As a further implementation method, the clamping device includes a clamping handle 11, a clamping fixing block 10 and a connecting threaded rod; one end of the connecting threaded rod passes through the waist hole 9 and is threadedly engaged with the locking seat 1; the clamping fixing block 10 is passed through the connecting threaded rod and does not rotate synchronously with the connecting threaded rod. The spacing between the clamping fixing block 10 and the second vertical plate is achieved by rotating the connecting threaded rod. The other end of the connecting threaded rod is hinged to the clamping handle 11, and the final clamping of the positioning baffle 3 is achieved by rotating the clamping handle 11 and cooperating with the cam structure.

[0033] As a further implementation, the hinged connection between the clamping handle 11 and the connecting threaded rod is formed into a cam structure, which compresses or loosens the clamping block 10. The cam-structured clamping handle 11, in conjunction with the connecting threaded rod and the clamping block 10, solves the problems of cumbersome operation and loose fixation associated with traditional fixing methods. By simply turning the clamping handle 11, the second riser can be quickly tightened or loosened using the mechanical principle of a cam. This provides convenient operation and reliable fixing, significantly improving operational efficiency and saving manpower and time compared to traditional, complex fixing methods.

[0034] The fixing device cooperates with the adjustment structure of the positioning baffle 3, the clamping device and the locking baffle 2, making the entire fixing process easy to operate and flexible to adjust; the locking baffle 2 is first used to initially limit the position, and then the clamping device of the positioning baffle 3 is used to complete the final fixation, which not only ensures the fixing efficiency, but also ensures the stable constraint of the wheel, meeting the safety and stability requirements of the wheeled medical equipment during use.

According to the size of the wheel to be fixed, insert the first vertical plate of the locking baffle 2 into the appropriate adjusting groove 8 to preliminarily adapt the position in the width direction of the wheel; move the locking baffle 2 to a suitable height so that the first vertical plate and the first inclined plate can fit the side of the wheel; align the limiting groove 5 on the locking baffle 2 with the locking hole 6 above the adjusting groove 8, insert the locking pin 7 into the locking hole 6, and make it pass through the corresponding limiting groove 5; through the cooperation of the locking pin 7 with different limiting grooves 5, the locking baffle 2 is adjusted and positioned in the height direction, thereby preliminarily limiting the wheel in the lateral direction.

[0036] S2. Adjust the relative position between the second vertical plate and the locking seat 1 so that the positioning baffle 3 can fit with the other side of the wheel, and use the multiple waist holes 9 and the clamping device on the second vertical plate to fix it, rotate the connecting threaded rod to adjust the clamping and fixing block 10 to just fit the second vertical plate, and rotate the clamping handle 11 to use the cam structure to compress the clamping and fixing block 10. The cam structure can make the clamping and fixing block 10 generate greater pressure to firmly fix the positioning baffle 3 in the appropriate position, ensure the stable positioning of the wheel by the positioning baffle 3, avoid loosening of the wheel due to loose fixation, ensure that the medical equipment is fixed reliably, thereby fixing the position of the second vertical plate so that the positioning baffle 3 can firmly rest against the other side of the wheel.
