Description

Technical Field

[0001] This invention relates to the field of medical care equipment technology, and in particular to a protective component for a nursing / medical bed. Background Technology

[0002] Bed rails are widely used as optional accessories for medical beds and home care beds. They are usually used in conjunction with full-coverage guardrails to prevent users from accidentally falling or falling off the bed during activities such as moving or turning over.

[0003] For example, a medical nursing bed mentioned in patent CN215020798U includes a bed board, headboards at both ends of the bed board, bed legs supporting the bed board, and railings on both sides of the bed board starting from one of the headboards. The ends of the railings and the other headboard form an upper and lower position for the nursing bed. A protective railing is also provided at the upper and lower position, and the protective railing is movably installed between the ends of the railings and the headboard.

[0004] For example, patent CN211705110U mentions a nursing bed anti-collision and anti-hook guardrail mechanism, which includes a bed frame and a guardrail mechanism. The guardrail mechanism is composed of a crossbeam and several longitudinal beams connected together. The guardrail mechanism is characterized in that it also includes several arc-shaped adapter rods. The tail end of the arc-shaped adapter rod is inserted into the bed frame and fastened with a nut. The front end of the arc-shaped adapter rod is hollow, and the longitudinal beams are inserted and installed in the hollow front end of the arc-shaped adapter rod.

[0005] The guardrail structures described in the aforementioned patents, when assembled with nursing or medical beds, fail to meet safety regulations regarding the gap between the guardrail and the headboard, posing a risk of jamming during use. Furthermore, these guardrail structures are directly fixed to the bed frame, requiring pre-drilled connection holes. However, altering the position of these holes to meet the required gap between the guardrail and headboard presents another problem: there are no specific requirements for guardrail structure selection for either nursing or medical beds; guardrail lengths and fixing positions vary. Replacing the connection holes on the bed frame with a different one requires determining the guardrail length, installation position, and other parameters before determining the connection holes, which is cumbersome. Moreover, this method necessitates a one-to-one match between the bed and guardrail, limiting versatility. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a protective component for nursing / medical beds that can meet the gap between the guardrail and the headboard and avoid the occurrence of clamping.

[0007] To solve the above-mentioned technical problems, the technical solution of the present invention is: a telescopic transport support beam, the innovation of which is that the protective component is installed on the bed frame of the nursing bed or medical bed; The protective components include guardrails installed on both sides of the bed frame, and the two sides of the guardrails are fixed to the bed frame by the cooperation of fixing components; The fixing assembly includes a fixing plate, a fixing sleeve, and a fixing component. The fixing plate is horizontally arranged, with one side connected to the bed frame and the other side connected to the fixing sleeve. The fixing sleeve has an insertion hole, and each side of the guardrail has an insertion section that inserts into the insertion hole of the fixing sleeve. The insertion section of the guardrail is then fixed by the fixing component after being inserted into the insertion hole of the fixing sleeve.

[0008] Furthermore, the fixing plate is a Z-shaped bent plate, including a first horizontal section, a second inclined section and a third horizontal section connected in sequence. The third horizontal section is fixed to the bed frame by bolts and nuts. The inclination direction of the second inclined section is gradually inclined away from the bed frame from the connection side of the second inclined section and the third horizontal section. The distance between the first horizontal section and the bed frame is greater than the distance between the third horizontal section and the bed frame. The fixing sleeve is composed of an inner plastic sleeve and a outer metal sleeve. The inner plastic sleeve has a plug hole for inserting the guardrail plug section, and the outer metal sleeve has an embedding hole for inserting the inner plastic sleeve. The outer metal sleeve is fixed to the first horizontal section by locking screws. The fastener includes a pin, a spring, a pin cap, and an open retaining ring. The pin cap is located on the outside of the metal outer sleeve. After the pin passes horizontally through the pin cap, one side of the pin extends into the fixing sleeve, and the other side is fixed by the open retaining ring. Through holes for the pin to pass through are also provided on the metal outer sleeve, the plastic inner sleeve, and the insertion section of the guardrail. After the insertion section of the guardrail is inserted into the insertion hole of the plastic inner sleeve, the pin passes through the through holes on the metal outer sleeve, the plastic inner sleeve, and the insertion section of the guardrail in sequence to achieve the fixation between the guardrail and the fixing sleeve. A spring is also fitted on the outer wall of the pin.

[0009] Furthermore, a gap is left between the outer wall of the plastic inner sleeve and the metal outer sleeve. Several fixing ribs are also provided on the outer wall of the plastic inner sleeve, distributed along the circumference of the outer wall of the plastic inner sleeve, and the outer wall of the fixing ribs is tightly fitted with the inner wall of the metal outer sleeve.

[0010] Furthermore, there are two through holes on the plastic inner sleeve for the pin to pass through, which are distributed vertically on the plastic inner sleeve.

[0011] Furthermore, the metal outer sleeve is also provided with a protruding first column and a second column. The first column has an internal threaded hole that mates with a tightening screw. The tightening screw passes through the through hole on the first horizontal section and engages with the internal threaded hole of the first column, thereby fixing the first horizontal section to the metal outer sleeve. The second column has a through hole for a pin to pass through. The pin head is fitted on the outer wall of the second column. The pin passes through the through hole of the second column and then through the through holes on the metal outer sleeve, the plastic inner sleeve, and the insertion section of the guardrail. The spring is also placed in the through hole of the second column, with one side of the spring abutting against the pin and the other side abutting against the inner wall of the second column.

[0012] Furthermore, the guardrail is a split guardrail, consisting of two opposing guardrail sections. Each guardrail section includes posts and crossbars. There are two posts, namely a first post and a second post. The tops of the first post and the second post are connected by an arc-shaped connecting rod, forming an inverted U-shaped post. There are several crossbars, which are connected from top to bottom to the side of the second post away from the first post. Each crossbar of the two guardrail sections corresponds to the other. Each crossbar of one guardrail section is provided with a guide connecting sleeve on the side away from the second post. Each crossbar of the other guardrail section is inserted into the guide connecting sleeve and extends into the crossbar with the guide connecting sleeve, thereby connecting the two guardrail sections to form a complete guardrail. The bottom of the first column has a plug section for inserting a fixing sleeve into a plug hole, and several through holes for accommodating pins are also opened on the first column at the plug section, arranged sequentially from top to bottom.

[0013] Furthermore, a vertically arranged first reinforcing bar is provided between the horizontal bars of one of the guardrail segments, and the first reinforcing bar is located on the side of the guardrail segment adjacent to the other guardrail segment.

[0014] Furthermore, a second reinforcing rod is horizontally arranged between the first column and the second column, and the second reinforcing rod is located on the side close to the connecting rod.

[0015] The advantages of this invention are as follows: The protective component of this invention, by adding a fixing component to cooperate with the guardrail, achieves the fixation between the guardrail and the bed frame, thereby adjusting the distance between the guardrail and the headboard of the bed frame to meet the requirements of the nursing bed or medical bed for this distance, avoiding the phenomenon of being pinched, and reducing the risk of using the nursing bed or medical bed.

[0016] By leaving a gap between the plastic inner sleeve and the metal outer sleeve, and with the design of fixing ribs, the plastic inner sleeve and the metal outer sleeve are relatively fixed. This eliminates the need for the outer wall of the plastic inner sleeve to be directly attached to the inner wall of the metal outer sleeve for connection. This reduces the precision required for the fit between the plastic inner sleeve and the metal outer sleeve, and facilitates the processing of the plastic inner sleeve and the metal outer sleeve.

[0017] The guardrail is designed as a two-part structure, allowing the crossbar of one guardrail part to slide horizontally along the crossbar of the other guardrail part. By changing the relative position between the two guardrail parts, the length of the guardrail can be adjusted to suit various working conditions.

[0018] The design of the first reinforcing bar strengthens and stabilizes the structure between the crossbars, ultimately improving the overall structural strength of the guardrail. Similarly, the design of the second reinforcing bar strengthens the connection between the first and second posts, providing a good foundation for improving the overall structural strength of the guardrail.

[0019] The protective component for nursing / medical beds of the present invention has a simple structure, ingenious design, and is easy to install, disassemble, and maintain. It can be purchased by customers as an accessory as needed, saving overall costs and better meeting current safety regulations. Attached Figure Description

[0027] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0028] like Figures 1-7 The illustration shows a protective component for a nursing / medical bed, which is mounted on the bed frame 1 of the nursing or medical bed.

[0029] The protective components include guardrails 2 installed on both sides of the bed frame 1, and the two sides of the guardrails 2 are fixed to the bed frame 1 by the cooperation of the fixing components 3.

[0030] like Figure 4 As shown in the schematic diagram, the fixing component 3 includes a fixing plate 31, a fixing sleeve 32, and a fixing member. The fixing plate 31 is horizontally arranged, and one side of the fixing plate 31 is connected to the bed frame 1, while the other side of the fixing plate 31 is connected to the fixing sleeve 32. The fixing sleeve 32 has an insertion hole, and the guardrail 2 has an insertion section on each side that is inserted into the insertion hole of the fixing sleeve 32. After the insertion section of the guardrail 3 is inserted into the insertion hole of the fixing sleeve 32, it is fixed by the fixing member.

[0031] The fixing plate 31 is a Z-shaped bent plate, including a first horizontal section 311, a second inclined section 312 and a third horizontal section 313 connected in sequence. The third horizontal section 313 is fixedly connected to the bed frame 1 by bolts and nuts. The inclination direction of the second inclined section 312 is gradually inclined away from the bed frame 1 from the connection side of the second inclined section 312 and the third horizontal section 313. The distance between the first horizontal section 11 and the bed frame 1 is greater than the distance between the third horizontal section 313 and the bed frame 1.

[0032] The fixing sleeve 32 is composed of an inner plastic sleeve 321 and a metal outer sleeve 322. The inner plastic sleeve 321 has a plug hole for inserting the plug section of the guardrail 2, and the metal outer sleeve 322 has an embedding hole for inserting the inner plastic sleeve 321. The metal outer sleeve 322 is fixed to the first horizontal section 311 by the cooperation of the locking screw 33.

[0033] In this invention, the plastic inner sleeve 321 is fitted onto the outer wall of the guardrail 2. Therefore, the plastic inner sleeve 321 is made of plastic to prevent damage to the guardrail 2 during use.

[0034] A gap is left between the outer wall of the plastic inner sleeve 321 and the metal outer sleeve 322. Several fixing ribs 323 are also provided on the outer wall of the plastic inner sleeve 321, distributed along the circumference of the outer wall of the plastic inner sleeve 321, and the outer wall of the fixing ribs 323 is tightly fitted with the inner wall of the metal outer sleeve 322. By leaving a gap between the plastic inner sleeve 321 and the metal outer sleeve 322, and with the design of the fixing ribs 323, the relative fixation between the plastic inner sleeve 321 and the metal outer sleeve 322 is achieved. This eliminates the need for the outer wall of the plastic inner sleeve 321 to be directly fitted to the inner wall of the metal outer sleeve 322 for connection, thus reducing the precision required for the fit between the plastic inner sleeve 321 and the metal outer sleeve 322 and facilitating the processing of the plastic inner sleeve 321 and the metal outer sleeve 322.

[0035] The fasteners include a pin 34, a spring 35, a pin cap 36, and an open retaining ring 37. The pin cap 36 is located outside the metal outer sleeve 322. After the pin 34 passes horizontally through the pin cap 36, one side of the pin 34 extends into the fixing sleeve, and the other side of the pin 34 is limited and fixed by the open retaining ring 37. An annular groove for the open retaining ring 37 is also formed on the outer wall of the pin 34. After the open retaining ring 37 is inserted into the groove on the pin 34, the outer circumference of the open retaining ring 37 is... The outer circumference of the exposed pin 34 has through holes for the pin 34 to pass through on the metal outer sleeve 322, the plastic inner sleeve 321, and the insertion section of the guardrail 2. After the insertion section of the guardrail 2 is inserted into the insertion hole of the plastic inner sleeve 321, the pin 34 passes through the through holes on the metal outer sleeve 322, the plastic inner sleeve 321, and the insertion section of the guardrail 2 in sequence to fix the guardrail 2 to the fixing sleeve 32. A spring 35 is also fitted on the outer wall of the pin 34.

[0036] There are two through holes for the accommodating pins 34 on the inner plastic sleeve 321, positioned vertically. The use of two through holes for the accommodating pins 34 on the inner plastic sleeve 321 allows for adjustment of its vertical position as needed, enabling it to better fit the guardrail 2 and provide protection.

[0037] The metal outer sleeve 322 is also provided with a protruding first column 38 and a second column 39. The first column 38 has an internal threaded hole that mates with the tightening screw 33. The tightening screw 33 passes through the through hole on the first horizontal section 311 and engages with the internal threaded hole of the first column 38, thereby fixing the first horizontal section 311 and the metal outer sleeve 322. A first annular washer 331 is also fitted on the outer wall of the tightening screw 33, and the first annular washer 331 is located between the first column 38 and the first horizontal section 311.

[0038] The second pillar 39 has a through hole through which a pin 34 passes, and a pin cap 36 is fitted onto the outer wall of the second pillar 39, as shown. Figure 6 As shown, the pin 34 passes through the through hole of the second post 39, and then through the through holes of the metal outer sleeve 322, the plastic inner sleeve 321, and the insertion section of the guardrail 2. The spring 35 is also placed in the through hole of the second post 39. One side of the spring 35 abuts against the pin 34, and the other side abuts against the inner wall of the second post 39. A second annular washer 341 is also fitted on the outer wall of the pin 34, and the second annular washer 341 is located between the second post 39 and the pin head 36. The spring 35 is designed to cooperate with the pin 34 to provide a certain tension to the pin 34, so that the pin 34 can be stably inserted into the through holes of the metal outer sleeve 322, the plastic inner sleeve 321, and the insertion section of the guardrail 2, avoiding loosening and ensuring the stability of the connection.

[0039] Both the first annular washer 331 and the second annular washer 341 are made of carbon steel. The first annular washer 331 is used to cooperate with the locking screw 33 to limit the range of motion of the fixing plate 31, and the second annular washer 341 is used to reduce the wear of the pin head 36.

[0040] like Figure 3As shown in the schematic diagram, guardrail 2 is a split-type guardrail, composed of two opposing guardrail sections. Each guardrail section includes posts and crossbars. There are two posts, namely the first post 21 and the second post 22. The tops of the first post 21 and the second post 22 are connected by an arc-shaped connecting rod 23, forming an inverted U-shaped post. There are several crossbars 24, which are connected from top to bottom to the side of the second post 22 away from the first post 21. The crossbars 24 of the two guardrail sections correspond one-to-one. The dimensions of each crossbar 24 of one guardrail section are larger than those of each crossbar 24 of the other guardrail section to ensure a smaller overall size. The crossbars 24 can extend into the larger crossbars 24. A guide sleeve 25 is also provided on the side of each larger crossbar 24 away from the second post 22. This guide sleeve 25 serves two purposes: firstly, it guides the smaller crossbars 24 as they extend, and secondly, it reinforces and protects the end of the larger crossbar 24 on that side, preventing damage. Each smaller crossbar 24 is inserted into its corresponding guide sleeve 25 and then extends into the larger crossbar 24, thus connecting the two separate guardrail sections to form a complete guardrail. The guardrail design employs a split-section design, allowing the crossbars 24 of one guardrail section to slide horizontally along the crossbars 24 of the other. By changing the relative position between the two guardrail sections, the length of the guardrail can be adjusted to suit various working conditions.

[0041] The bottom of the first post 21 has a plug section for inserting into the plug hole of the fixing sleeve 32. Several through holes 211, arranged from top to bottom, are also opened on the first post 31 at the plug section for accommodating pins 34. By cooperating with the several through holes 211 arranged vertically, the vertical position of the guardrail and the fixing sleeve 32 can be adjusted to meet the needs of guardrails of different heights.

[0042] A vertically arranged first reinforcing rod 26 is also provided between the horizontal bars 24 of one of the guardrail segments, and the first reinforcing rod 26 is located on the side of the guardrail segment adjacent to the other guardrail segment. In this embodiment, the first reinforcing rod 26 connects the larger horizontal bars 24, and the first reinforcing rod 26 is located near the guide connecting sleeve 25 of the horizontal bar 24. The design of the first reinforcing rod 26 strengthens and stabilizes the structure between the horizontal bars 24, ultimately improving the structural strength of the entire guardrail. By placing the first reinforcing rod 26 on the side near the guide connecting sleeve 25, only one set of first reinforcing rods 26 is needed to enhance the structural strength of all the horizontal bars 24 of the two guardrail segments, reducing the number of first reinforcing rods 26 required.

[0043] A horizontally positioned second reinforcing rod 27 is also provided between the first post 21 and the second post 22, and the second reinforcing rod 27 is located on the side closer to the connecting rod 23. Similarly, the design of the second reinforcing rod 27 is to structurally strengthen the connection between the first post 21 and the second post 22, and also to provide a good foundation for improving the structural strength of the entire guardrail.

[0044] The protective component of the present invention, by adding a fixing component to cooperate with the guardrail 2, achieves the fixation between the guardrail 2 and the bed frame 1, thereby adjusting the distance between the guardrail 2 and the headboard of the bed frame 1 to meet the requirements of the nursing bed or medical bed for the distance, avoiding the phenomenon of being pinched, and reducing the risk of using the nursing bed or medical bed.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
