Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of medical equipment, in particular to a treatment bed. BACKGROUND
[0002] Treatment bed aims to provide comfortable treatment and rest environment for sick patient, when sick patient needs to carry out operation, ward transfer and other medical activities, treatment bed can be directly pushed to move to the position required, so it can reduce the frequency of moving bed for sick patient, and improve medical efficiency. At present, people usually exert force on the headboard of treatment bed when pushing treatment bed, to realize the control of treatment bed activity. Since the bed plate of treatment bed is fixed laterally on treatment bed, when the pushing and pulling force on treatment bed is too large, the connecting position between headboard and treatment bed is prone to loosen, which leads to the problem that headboard is separated from treatment bed. Therefore, there is an urgent need for a treatment bed with more stable structure. SUMMARY
[0003] The utility model aims to provide a kind of treatment bed, to solve one or more technical problems existing in prior art, at least provide a kind of beneficial selection or create conditions.
[0004] The solution of the technical problem of the utility model is as follows:
[0005] A kind of treatment bed, comprising: bed frame, left and right sides are respectively provided with side plate;Swivel frame, including the horizontal bar, vertical rod and guardrail rod being connected with each other, the horizontal bar extends along front and back direction, the vertical rod is connected to the front end of the horizontal bar and extends downward, the guardrail rod is connected to the rear end of the horizontal bar, the front end of the horizontal bar is rotationally connected to one side plate, the horizontal bar can be rotated to vertical state and be positioned or be rotated to horizontal state and be positioned upward, the left and right sides of the bed frame are both provided with the swivel frame.
[0006] The technical scheme has at least the following beneficial effects: according to different use requirements, the rotating frame on the left and right sides of the bed frame can be used as a guardrail on the two sides of the bed or as a handrail when the treatment bed is moved, specifically, when normally used, the horizontal rod in the rotating frame is positioned on the side plate to be horizontal, at this time, the vertical rod at the front end of the horizontal rod is in a vertical downward state, and the guardrail rod at the rear end of the horizontal rod is located at the side of the bed frame, which can protect the patient lying on the bed frame, when the treatment bed needs to be moved, the positioning of the horizontal rod is released, and the horizontal rod is positioned by being turned upward to be vertical, at this time, the horizontal rod lifts the height of the guardrail rod, and the user can conveniently exert force on the guardrail rod and use the guardrail rod as a handrail to control the movement of the bed frame, since the connection position of the rotating frame and the bed frame is located on the left and right sides of the bed frame, the user is less likely to directly pull the rotating frame out of the bed frame when moving the bed frame, thereby improving the overall structural stability when the bed frame is controlled to move, so that the rotating frame provided on the two sides of the bed frame not only serves as a guardrail, but also serves as a handrail when the bed frame is controlled to move, the use function is more diversified, the rotating frame is less likely to be pulled out of the bed frame when force is exerted on the rotating frame, the overall structure is more stable, and the practicality is stronger.
[0007] As a further improvement of the above technical scheme, a connecting shaft is formed on the side of the horizontal rod opposite to the bed frame, the connecting shaft penetrates through the side plate, a spring is arranged between the connecting shaft and the side plate, a rotation stopping tooth is arranged outside the connecting shaft, a plurality of rotation stopping holes are arranged around the position of the connecting shaft of the side plate, and the spring can drive the connecting shaft to move along the axial direction and make the rotation stopping tooth be matched and connected in one rotation stopping hole. In a natural state, due to the limitation of the spring, the rotation stopping tooth on the connecting shaft is matched and connected in the rotation stopping hole, the mutual cooperation of the two can limit the rotation of the connecting shaft, so as to keep the horizontal rod in a vertical or horizontal state, when the rotating frame needs to be rotated, the connecting shaft is moved along the axial direction, so that the rotation stopping tooth is pulled out of the rotation stopping hole, at this time, the spring is elastically deformed, and the connecting shaft can be rotated, after the position of the horizontal rod is adjusted, the external force on the connecting shaft is removed, the elastic restoring force of the spring can drive the connecting shaft to move along the axial direction, so that the rotation stopping tooth is connected to the rotation stopping hole opposite to it, and the rotation stopping limitation of the connecting shaft is re-implemented, so as to keep the position state of the horizontal rod.
[0008] As a further improvement of the above technical solution, the end of the connecting shaft away from the crossbar forms a limiting shoulder, and the two ends of the spring are respectively abutted against the limiting shoulder and the side plate. The spring is sleeved outside the end of the connecting shaft passing through the side plate. At this time, the limiting shoulder can be pushed away from the side plate by the spring itself. The limiting shoulder drives the crossbar to approach the side plate through the connecting shaft, and the stop gear on the connecting shaft is connected to the stop hole, thereby limiting the rotation of the connecting shaft. When the connecting shaft needs to be rotated, the crossbar is pulled away from the side plate, so that the stop gear on the connecting shaft is disengaged from the stop hole. At this time, the spring between the limiting shoulder and the side plate is elastically compressed. When the position adjustment of the rotating frame is completed, the pulling force on the rotating frame is removed, and the elastic force of the spring makes the stop gear re-connect to the stop hole.
[0009] As a further improvement of the above technical solution, the crossbar is connected with a pull ring away from the connecting shaft. When the crossbar needs to be pulled away from the side plate, force can be applied to the pull ring. The pull ring can improve the convenience of applying force and make it easier to disengage the stop gear on the connecting shaft from the stop hole.
[0010] As a further improvement of the above technical solution, the side plate is provided with limiting protrusions on both sides of the crossbar. When the crossbar is in a horizontal state, the two limiting protrusions are respectively abutted against the upper and lower sides of the crossbar. When the crossbar is in a vertical state, the two limiting protrusions are respectively abutted against the upper and lower sides of the vertical bar. The limiting protrusions on the side plate clamp and position the upper and lower sides of the crossbar. When the position of the rotating frame needs to be adjusted, the crossbar is pulled away from the side plate. At this time, the crossbar in the horizontal state moves out of the two limiting protrusions. After the crossbar is turned up to the position, the vertical bar is turned to between the two limiting protrusions. When the external force on the crossbar is removed, the elastic force of the spring makes the vertical bar approach the side plate, thereby limiting the vertical movement between the two limiting protrusions. When force is applied to the rotating frame to control the movement of the bed frame, the two limiting protrusions can limit the vertical bar, which can effectively improve the stability of the rotating frame when it is subjected to external force, and the overall structure is more stable.
[0011] As a further improvement of the above technical solution, the side plate is connected with a shaft sleeve away from the crossbar, the connecting shaft passes through the shaft sleeve, and the spring is sleeved outside the shaft sleeve. The shaft sleeve on the side plate cooperates with the connecting shaft. The shaft sleeve further limits the connecting shaft, which can effectively improve the structural stability of the connecting shaft and the side plate connection, and reduce the shaking of the connecting shaft under stress.
[0012] As a further improvement to the above technical solution, an extension plate is slidably connected to the bottom side of the bed frame in the front-to-back direction. The extension plate can slide backward out of the bed frame or retract forward into the bottom side of the bed frame. When a patient on the bed frame needs to move to the rear of the bed frame to change position, the extension plate can be pulled out from the bottom side of the bed frame. This extends the area that the bed frame can support in the front-to-back direction, thereby providing better support for the patient and improving the convenience of medical activities.
[0013] As a further improvement to the above technical solution, guardrails are slidably connected to the two side panels on opposite sides in the front-rear direction, and the rear sides of the two guardrails are respectively connected to the rear side of the extension plate. The guardrails on the two side panels can prevent falls from the bed frame on both sides, improving the protection for the patient. Furthermore, the rear side of the guardrails is connected to the extension plate; when the extension plate is pulled backward from the bottom of the bed frame, the guardrails also move backward with the extension plate, maintaining protection for the patient. The connection between the guardrails and the rear side of the extension plate provides a support connection point for the rear side of the extension plate, increasing the load-bearing capacity of the extension plate.
[0014] As a further improvement to the above technical solution, a locking block is provided on the rear side of the bed frame, and locking slots are provided on the front and rear sides of the extension plate, respectively. The locking block can be engaged with any of the locking slots. When the extension plate is fully located at the bottom of the bed frame, the locking block is engaged with the locking slot on the front side of the extension plate, thereby better maintaining the extension plate in its retracted state. When it is necessary to pull the extension plate out, the extension plate is pulled back, causing the locking block to disengage from the locking slot. When the extension plate is pulled out to its final position, the locking block engages with the locking slot on the rear side of the extension plate, thereby better maintaining the extension plate in its extended state from the bed frame and improving ease of use.
[0015] As a further improvement to the above technical solution, a drawer is provided on the front bottom side of the bed frame. Patients can store their belongings in the drawer, which is especially useful when the entire treatment bed needs to be moved, allowing patients to store their personal items and improving their user experience.

[0027] Reference Figures 1 to 3A treatment bed includes a bed frame 100 and a rotating frame. Side panels 110 are respectively provided on the left and right sides of the bed frame 100. The rotating frame includes interconnected horizontal bars 210, vertical bars 220, and guardrails 230. The horizontal bars 210 extend in a front-to-back direction, the vertical bars 220 are connected to the front end of the horizontal bars 210 and extend downwards, and the guardrails 230 are connected to the rear end of the horizontal bars 210. The guardrails 230 mainly serve to protect the sides of the bed frame 100. The guardrails 130 have an upwardly extending portion at the rear end of the horizontal bars 210 and a horizontally extending portion to provide a blocking and protective function. The front end of the horizontal bars 210 is rotatably connected to one of the side panels 110. The horizontal bars 210 can be rotated upwards to a vertical position and positioned, or rotated downwards to a horizontal position and positioned. The rotating frames are provided on both the left and right sides of the bed frame 100.
[0028] As described above, depending on different usage needs, the rotating frames on both sides of the bed frame 100 can be used as guardrails on both sides of the bed, or as handrails when moving the treatment bed. Specifically, during normal use, the crossbar 210 inside the rotating frame is positioned horizontally on the side panel 110. At this time, the vertical bar 220 at the front end of the crossbar 210 is vertically downward, and the guardrail 230 at the rear end of the crossbar 210 is located on the side of the bed frame 100, which can provide protection for patients lying on the bed frame 100. When it is necessary to move the treatment bed, the positioning of the crossbar 210 is released, and the crossbar 210 is rotated upward to a vertical position and then positioned. At this time, the crossbar 210 raises the guardrail 230. At its height, the user can easily grip the guardrail 230 and use it as a handrail to control the movement of the bed frame 100. Since the connection between the rotating frame and the bed frame 100 is located on the left and right sides of the bed frame 100, it is not easy for the rotating frame to detach directly from the bed frame 100 when the user pushes or pulls the bed frame 100. This improves the overall structural stability when controlling the movement of the bed frame 100. In this way, the rotating frame set on both sides of the bed frame 100 serves as both a guardrail and a handrail when controlling the movement of the bed frame 100, making its functions more diverse. Furthermore, the rotating frame is not easy to detach from the bed frame 100 when force is applied, making the overall structure more stable and practical.
[0029] The horizontal bar 210 is rotatably connected to the side plate 110. After rotation adjustment, it needs to be positioned. There are several ways to achieve this. For example, a positioning pin can be passed through the horizontal bar 210 or the vertical bar 220. When the horizontal bar 210 rotates to a horizontal position and needs positioning, a positioning pin is passed through the horizontal bar 210 and connected to the side plate 110. When the horizontal bar 210 rotates to a vertical position and needs positioning, a positioning pin is passed through the vertical bar 220 and connected to the side plate 110. However, to improve the convenience of rotation adjustment and positioning, in this embodiment, as shown... Figure 4 and Figure 5As shown, a connecting shaft 211 is formed on the side of the crossbar 210 facing the bed frame 100. The connecting shaft 211 passes through the side plate 110. A spring 212 is provided between the connecting shaft 211 and the side plate 110. An anti-rotation tooth 213 is provided on the outer side of the connecting shaft 211. The side plate 110 is provided with multiple anti-rotation holes around the position of the connecting shaft 211. The spring 212 can drive the connecting shaft 211 to move axially and make the anti-rotation tooth 213 engage with one of the anti-rotation holes. In practical applications, multiple anti-rotation teeth 213 can be provided on the outer side of the connecting shaft 211. For example, anti-rotation teeth 213 are provided on both sides of the connecting shaft 211. In this case, four anti-rotation holes are provided on the side plate 110 around the connecting shaft 211. Two anti-rotation teeth 213 can engage with two anti-rotation holes facing each other to achieve rotational positioning of the crossbar 210. In its natural state, due to the constraint of spring 212, the anti-rotation tooth 213 on the connecting shaft 211 is engaged with the anti-rotation hole. The interaction between the two restricts the rotation of the connecting shaft 211, thereby keeping the crossbar 210 in a vertical or horizontal position. When the frame needs to be rotated, the connecting shaft 211 is moved axially, causing the anti-rotation tooth 213 to disengage from the anti-rotation hole. At this time, spring 212 is elastically deformed, and the connecting shaft 211 can rotate. After the position of the crossbar 210 is adjusted, the external force on the connecting shaft 211 is removed. The elastic force of the spring 212 can drive the connecting shaft 211 to move axially, so that the anti-rotation tooth 213 is engaged with the anti-rotation hole opposite it, thus restoring the anti-rotation constraint on the connecting shaft 211 and maintaining the position of the crossbar 210.
[0030] In the above embodiments, the spring 212 can be a tension spring 212 or a compression spring 212. In order to improve the stability during use, in this embodiment, the spring 212 can be a compression type. Specifically, the end of the connecting shaft 211 away from the crossbar 210 forms a limiting shoulder 214, and the two ends of the spring 212 abut against the limiting shoulder 214 and the side plate 110 respectively. Spring 212 is sleeved on the outer side of the end of connecting shaft 211 that passes through side plate 110. At this time, spring 212 itself can push the limiting shoulder 214 away from side plate 110. The limiting shoulder 214 then drives the crossbar 210 closer to side plate 110 through connecting shaft 211, and makes the anti-rotation tooth 213 on connecting shaft 211 engage with the anti-rotation hole to restrict the rotation of connecting shaft 211. When it is necessary to rotate connecting shaft 211, the crossbar 210 is pulled away from side plate 110, so that the anti-rotation tooth 213 on connecting shaft 211 disengages from the anti-rotation hole. At this time, spring 212 between limiting shoulder 214 and side plate 110 is elastically compressed. After the position of the rotating frame is adjusted, the pulling force of the rotating frame is removed, and the elastic force restored by spring 212 makes the anti-rotation tooth 213 re-engage with the anti-rotation hole.
[0031] Because the crossbar 210 has a small contact area, it is difficult to apply force when pulling it outward. Therefore, to improve the user experience, in this embodiment, a pull ring is connected to the side of the crossbar 210 away from the connecting shaft 211. When it is necessary to pull the crossbar 210 away from the side plate 110, force can be applied to the pull ring. The pull ring improves the ease of applying force and makes it easier to disengage the anti-rotation tooth 213 on the connecting shaft 211 from the anti-rotation hole.
[0032] To further improve the structural stability of the rotating frame under external force, in this embodiment, the side plate 110 is provided with limiting protrusions 111 on the upper and lower sides of the crossbar 210. When the crossbar 210 is in a horizontal state, the two limiting protrusions 111 abut against the upper and lower sides of the crossbar 210 respectively; when the crossbar 210 is in a vertical state, the two limiting protrusions 111 abut against the upper and lower sides of the vertical bar 220 respectively. Limiting protrusions 111 are provided on the side plate 110 to clamp and position the crossbar 210 on both sides. When the position of the rotating frame needs to be adjusted, the crossbar 210 is pulled away from the side plate 110. At this time, the horizontal crossbar 210 moves out of the space between the two limiting protrusions 111. After the crossbar 210 is rotated upward to the position, the vertical bar 220 rotates to the space between the two limiting protrusions 111. When the external force on the crossbar 210 is removed, the elastic force of the spring 212 makes the vertical bar 220 move closer to the side plate 110, thereby making it vertically move to the space between the two limiting protrusions 111. When the rotating frame is applied to control the movement of the bed frame 100, the vertical bar 220 is limited in the upper and lower parts by the two limiting protrusions 111, which can effectively improve the stability of the rotating frame when subjected to external force, and the overall structure is more stable.
[0033] The connecting shaft 211 is fitted with a shaft hole to allow it to rotate relative to the side plate 110 and move in the left-right direction relative to the side plate 110. To improve the structural stability of the connection position, in this embodiment, a bushing 112 is connected to the side of the side plate 110 away from the crossbar 210. The connecting shaft 211 passes through the bushing 112, and the spring 212 is sleeved on the outside of the bushing 112. The bushing 112, which cooperates with the connecting shaft 211, is provided on the side plate 110. Using the bushing 112 to further limit the connection of the connecting shaft 211 effectively improves the structural stability of the connection between the connecting shaft 211 and the side plate 110, and reduces the likelihood of the connecting shaft 211 wobbling under stress.
[0034] In some embodiments, an extension plate 120 is slidably connected to the bottom side of the bed frame 100 in the front-to-back direction. The extension plate 120 can slide backward out of the bed frame 100 or retract forward into the bottom side of the bed frame 100. When a patient on the bed frame 100 needs to move to the rear position of the bed frame 100 to change position, the extension plate 120 can be pulled out from the bottom side of the bed frame 100. This extends the area that the bed frame 100 can support in the front-to-back direction, thereby providing better support for the patient and improving the convenience of medical activities.
[0035] The extension plate 120 can slide in the front-back direction by slidingly connecting to the bottom side of the bed frame 100 or by slidingly connecting to the side plates 110 on both sides. When the extension plate 120 is pulled out of the bed frame 100, the rear side of the extension plate 120 is directly suspended in the air. When the rear side of the extension plate 120 is subjected to excessive pressure, the sliding connection structure of the extension plate 120 is easily damaged. Therefore, in order to improve the structural stability of the extension plate 120, in this embodiment, guardrails 130 are slidably connected to the sides of the two side plates 110 that are far apart from each other in the front-back direction, and the rear sides of the two guardrails 130 are respectively connected to the rear side of the extension plate 120. The guardrails 130 on the two side panels 110 can prevent patients from falling out of bed on the left and right sides of the bed frame 100, thus improving the protection for patients. The rear side of the guardrails 130 is connected to the extension plate 120. When the extension plate 120 is pulled backward from the bottom side of the bed frame 100, the guardrails 130 also move backward with the extension plate 120, maintaining protection for patients. The connection between the guardrails 130 and the rear side of the extension plate 120 provides a support connection point for the rear side of the extension plate 120, thereby increasing the load-bearing capacity of the extension plate 120.
[0036] To better maintain the usability of the extension board 120, in this embodiment, a locking block is provided on the rear side of the bed frame 100, and locking slots are provided on the front and rear sides of the extension board 120. The locking block can be engaged with any of the locking slots. When the extension board 120 is fully located at the bottom of the bed frame 100, the locking block is engaged with the locking slot on the front side of the extension board 120, thereby better maintaining the extension board 120 in the retracted state. When it is necessary to pull out the extension board 120, the extension board 120 is pulled back, causing the locking block to disengage from the locking slot. When the extension board 120 is pulled out to its final position, the locking block is engaged with the locking slot on the rear side of the extension board 120, thereby better maintaining the extension board 120 in the extended state from the bed frame 100, improving ease of use.
[0037] In some embodiments, a drawer 140 is provided on the front bottom side of the bed frame 100. The patient's belongings can be stored in the drawer 140, which is especially useful when the entire treatment bed needs to be moved, allowing the patient to put their personal items in and improving the patient's user experience.
