Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a plug-in positioning bed guard and a medical bed. Background Technology

[0002] Currently, in medical and nursing settings, bed linens are crucial components for ensuring patient safety. They are primarily used to prevent patients from falling off the bed during turning or moving, and also facilitate patient transport and transfer during routine care. Whether it's a standard hospital bed in an inpatient ward or a specialized bed in an emergency room or operating room, the stability and ease of installation and removal of bed linens directly impact nursing efficiency and patient safety.

[0003] The existing bed linens for medical hospital beds have the following main problems:

[0004] Firstly, the bed linen is fixed to the bed frame and cannot be disassembled. This causes the bed linen to become an obstacle when moving patients, requiring multiple people to work together to get around it, which increases the workload of nursing staff and makes it easy for patients to bump into each other during the process.

[0005] Secondly, although the bed frame and bed body can be disassembled, the disassembly and assembly process is inconvenient. Some detachable bed frames are fixed with simple pins or buckles, lacking a secondary locking mechanism, resulting in poor stability and reliability of the assembled bed frame. In particular, after long-term use, the risk of falling off due to external forces and other factors increases. Utility Model Content

[0006] To address these issues, this invention provides a plug-in positioning bed guard and a medical bed, thereby solving the technical problems in the prior art where bed guards for medical beds are difficult to flexibly disassemble and assemble, and where detachable bed guards are not convenient or stable to disassemble and assemble, resulting in poor overall protective performance and synergistic effect of disassembly.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A plug-in positioning bed rail includes:

[0028] The positioning pin structure includes a positioning pressure plate;

[0029] The positioning plate is fixedly assembled to the opening of the pin positioning groove by several bolts, and the positioning plate and the pin positioning groove form a pressing action. The lower surface of the positioning plate is in close contact with the side wall of one end of the support pin, so that one end of the support pin is fixed inside the pin positioning groove, preventing the support pin from moving axially and radially during use.

[0060] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0061] The terms "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.

[0062] like Figures 1 to 5As shown, this utility model embodiment provides a plug-in positioning bed guard and a medical bed including the plug-in positioning bed guard. The plug-in positioning bed guard includes a guard base structure 1, a positioning pin structure 2, and a shift lock structure 3. The guard base structure 1 allows for direct fitting and limiting assembly with a predetermined bed frame protrusion. Simultaneously, the positioning pin structure allows for fitting and limiting assembly with a predetermined bed frame groove, and the shift lock structure further allows for locking with a predetermined bed frame lock groove. This effectively achieves multiple positioning between the bed guard and the bed frame, significantly improving assembly stability. Furthermore, it allows for direct insertion and removal with only one unlocking step, making it easier to assemble and disassemble, thus enhancing the overall protective performance and ease of disassembly of the bed guard. Specific details are as follows:

[0063] Please refer to Figures 1 to 3 The bed guard base structure 1 serves as the main support structure for the bed guard. Specifically, the bed guard base structure 1 includes a bed guard body 11, a limiting groove 12, a pin positioning groove 13, an anti-collision wheel assembly 14, a first limiting slide groove 15, and a second limiting slide groove 16. The bed guard body 11 is made of high-strength plastic material with predetermined toughness and load-bearing capacity. Arc-shaped plates are provided on both sides of the bed guard body 11. The radius of curvature of the arc-shaped plates is 5cm-8cm. This arc design eliminates the sharp edges of the bed guard, preventing patients or caregivers from being scratched when in contact with the plate. The inner sides of the arc-shaped plates on both sides of the bed guard body 11 correspond to the inner sides of the bed guard body 11, i.e., the side facing the center of the bed, thus ensuring that the protective effect of the arc-shaped plates is concentrated in the patient's activity area.

[0064] The bottom end of the guard plate body 11 is provided with a limiting groove 12 facing its inner side. The cross-section of the limiting groove 12 is U-shaped, and the width of the U-shaped limiting groove 12 is adapted to the width of the predetermined bed body protrusion. The adaptation tolerance between the two is ±0.5mm. It is used to install the guard plate at the predetermined bed body protrusion position through the limiting groove 12 to achieve the initial positioning between the guard plate and the bed body.

[0065] As a preferred embodiment, the inner wall of the limiting groove 12 is fixedly provided with a wear-resistant rubber pad with a thickness of 0.5mm-2mm, which is used to reduce wear caused by relative friction after the guard plate and the bed frame protrusion are assembled, and at the same time enhance the friction between the two and improve the stability of the initial positioning.

[0066] The main body 11 of the guard plate is provided with at least two sets of pin positioning grooves 13 (preferably two sets in this embodiment) connected to the upper part of the limiting groove 12. The two sets of pin positioning grooves 13 are arranged at intervals along the length direction of the main body 11 of the guard plate, so as to position and install the positioning pin structure 2 through the pin positioning grooves 13.

[0067] The pin positioning groove 13 has an arc-shaped cross-section, and its inner diameter is adapted to the outer diameter of the support pin 21. The adaptation tolerance between the two is ±0.2mm to ensure the fit of the support pin 21 when it is embedded.

[0068] Both sides of the bottom of the guard plate body 11 are provided with horizontally rotatable anti-collision wheel sets 14. The anti-collision wheel sets 14 include wheel frames and rollers. The wheel frames are rotatably connected to the bottom of the guard plate body 11. The rollers are made of polyurethane material with predetermined elasticity, and their diameter ranges from 5cm to 6cm. During the installation and removal of the guard plate, when the bed guard plate comes into contact with the bed frame, wall, etc., the rollers buffer the impact force through rotation and their own elasticity, avoiding direct damage to the guard plate body 11 and improving the self-protection of the guard plate base structure 1.

[0069] Please refer to Figure 1 and Figure 4 The positioning pin structure 2 is provided in at least two sets (in this embodiment, the number of sets matches the number of pin positioning grooves 13). Specifically, each set of positioning pin structures 2 includes a support pin 21, a positioning pressure plate 22, and an elastic sleeve 23. The support pin 21 is made of stainless steel and has high strength. One end of the support pin 21 (length range of 3cm-4cm) is embedded in the pin positioning groove 13. The positioning pressure plate 22 is made of metal and is fixedly assembled to the opening of the pin positioning groove 13 by several bolts. The positioning pressure plate 22 and the pin positioning groove 13 form a pressing action. The lower surface of the positioning pressure plate 22 is in close contact with the side wall of one end of the support pin 21, so that one end of the support pin 21 is fixed inside the pin positioning groove 13, thereby preventing the support pin 21 from moving axially and radially during use.

[0070] The elastic sleeve 23 is fixedly sleeved on the other end of the support pin 21, and the bottom end of the elastic sleeve 23 is provided with several sets of latches 231 at intervals. A predetermined gap is left between the latches 231 and the other end of the support pin 21, so as to provide space for the latches 231 to compress inward using the gap between the latches 231 and the support pin 21. The elastic sleeve 23 is also fixedly provided with spring support protrusions 232 on the outer side of the bottom end of its latches 231, so as to be simultaneously adapted and limited to the bed frame protrusion by the limiting slot 12 and the bed frame column groove by the elastic sleeve 23. At the same time, the latches 231 and the spring support protrusions 232 can be compressed inward based on the limiting effect of the bed frame column groove, so as to form a more stable insertion and assembly effect by means of the rebound energy of the latches 231 and the spring support protrusions 232. At the same time, it can be pulled out directly without the need for an additional unlocking mechanism, thus improving the functionality and practicality.

[0071] The elastic sleeve 23 may be made of, but is not limited to, elastic rubber or TPE material.

[0072] When the bed cover is assembled into the bed frame, the elastic retainer 23 is inserted into the bed frame column groove pre-set by the support pin 21. The retaining tongue 231 and the spring support protrusion 232 are compressed inward by the squeezing action of the inner wall of the groove based on the distance between them and the support pin 21. After full insertion, the spring support protrusion 232 forms a rebound contact action corresponding to the inner wall of the bed frame column groove under the elastic action of the retaining tongue 231, thereby forming a stable insertion support assembly. When disassembly is required, the retaining tongue 231 and the spring support protrusion 232 can be pulled out directly from the bed frame column groove under the action of pulling force, without the need for an additional unlocking mechanism, which effectively improves the convenience of function.

[0073] Please refer to Figure 1 and Figure 5 The main body 11 of the guard plate is also provided with a first limiting slide groove 15 facing its inner side and a second limiting slide groove 16 located at the bottom of the first limiting slide groove 15. The sliding direction of the first limiting slide groove 15 is parallel to the sliding direction of the second limiting slide groove 16, and the length of the first limiting slide groove 15 is greater than the length of the second limiting slide groove 16 (in this embodiment, the length of the first limiting slide groove 15 is 8cm and the length of the second limiting slide groove 16 is 6cm). Both extend along the length direction of the main body 11 of the guard plate so as to install the shift lock body structure 3 by cooperating with the two sets of limiting slide grooves.

[0074] Specifically, the shift lock body structure 3 includes a basic shift slider 31, a transmission shift slider 32, and a locking protrusion 33; wherein, the basic shift slider 31 is laterally slidably disposed in the second limiting slide groove 16, and an identification slide button is provided on the outer side of the guard plate body 11. The identification slide button protrudes 0.5cm from the surface of the guard plate body 11 to facilitate operation by the operator, and the identification slide button is provided with "lock on" and "unlock off" markings for easier identification of operation.

[0075] The transmission shift slider 32 is made of metal and is connected to the basic shift slider 31 in a transmission and fixed manner. The transmission shift slider 32 is laterally slidably disposed in the first limiting groove 15 so that the transmission shift slider 32 can slide synchronously with the basic shift slider 31 along the length direction of the groove.

[0076] The locking protrusion 33 is made of metal and is vertically fixed to the inner surface of the transmission shift slider 32. The diameter of the locking protrusion 33 is adapted to the inner diameter of the predetermined locking groove at the position of the bed frame protrusion (adaptation tolerance is ±0.2mm). When locking is required, the operator moves the marked slide button on the basic shift slider 31, causing the transmission shift slider 32 to slide along the first limiting slide groove 15, so that the locking protrusion 33 is inserted into the bed frame locking groove, thereby locking the bed guard plate to the bed frame. When unlocking is required, the marked slide button is moved in the opposite direction, and the locking protrusion 33 is pulled out of the bed frame locking groove, releasing the lock. At the same time, the sliding cooperation between the basic shift slider 31 and the second limiting slide groove 16, and between the transmission shift slider 32 and the first limiting slide groove 15, forms a double sliding limiting effect, effectively improving the control stability of the lateral sliding of the locking protrusion 33 and its alignment accuracy with the predetermined locking groove.

[0077] In this embodiment, the overall assembly process of the bed frame is as follows:

[0078] The operator aligns the limiting slot 12 of the guard plate body 11 with the bed frame protrusion and lowers the guard plate vertically, so that the limiting slot 12 and the bed frame protrusion are fitted and engaged (initial positioning); at this time, the elastic sleeve 23 moves down with the guard plate and is inserted into the preset column groove of the bed frame. The latch 231 is compressed inward under the pressure of the inner wall of the column groove. After it is fully inserted, the latch 231 and the spring support protrusion 232 rebound and press against the inner wall of the column groove (secondary positioning); finally, the operator moves the marked slide button of the basic shift slider 31 to insert the locking protrusion 33 into the bed frame locking groove (tertiary fixing), thus completing the overall assembly process of the bed guard plate.

[0079] The disassembly process is as follows: Move the marked slider button of the basic shift slider 31 in the opposite direction to pull the locking protrusion 33 out of the bed lock groove (release the third-level fixation); pull the guard plate outward, and the latch 231 and spring support protrusion 232 of the elastic sleeve 23 will directly disengage from the bed column groove under the action of the pulling force (release the second-level positioning); continue to pull the bed guard plate to separate the limiting slot 12 from the bed protrusion (release the initial positioning), and the disassembly is completed.

[0080] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
