Description

Technical Field

[0001] The present application relates to the technical field of orthopedic beds, and in particular to a safety movable belt structure for shielding slots. Background Art

[0002] The areas through which moving structures in current medical equipment pass must meet user-friendly appearance and safety requirements, both within the human body and within visual range. Slots on a flat surface created to allow for the movement of moving objects are typically shielded and protected. For example, on one side of an orthopedic bed, slots are provided in the horizontal frame to allow for the adjustment of the curved guide rails. The curved guide rails are driven by belts and other mechanisms, while the openings within the bed for the rails are primarily shielded with brushes, sponges, rubber, or airbags, providing both protection and a warning function.

[0003] The aforementioned shielding elements function by deforming, resulting in uneven deformation between the areas where the moving object passes, the areas where the moving object does not pass, and the transition areas. If the moving object remains stationary for a long time, permanent deformation may occur, affecting the appearance. The shielding elements also frequently rub against each other during movement, causing wear and tear and loss, shortening their service life. Furthermore, during use, there is a risk of foreign objects or human body parts being trapped, causing safety accidents. Therefore, to address the aforementioned issues, the present application provides a safety moving belt structure that blocks the slots. Utility Model Content

[0004] In order to solve the problem that the shielding materials on the existing bed are easily deformed and fall off, and the protection is not comprehensive enough, the present application provides a safety moving belt structure for shielding the slot.

[0005] The present application provides a safety movable belt structure for shielding a notch, comprising a side frame and a horizontal frame constituting a partial frame of a bed. The horizontal frame is vertically welded to one side of the top end of the side frame. The top end of the horizontal frame is provided with a notch for the movement of an arc-shaped guide rail. A shielding belt that cyclically moves to form a certain rotation space is slidably embedded in the inner side of the notch, and the shielding belt is always kept in a tensioned state.

[0006] The shielding strip shields the top view of the notch, and the shielding strip is flush with the upper end surface of the horizontal frame;

[0007] The arc-shaped guide rail is fixedly mounted on the shielding belt through a connecting piece and moves synchronously with the shielding belt.

[0008] The taut shielding belt in circular motion completely covers the top of the slot, preventing foreign objects from entering the bed frame, and has a good protective effect. At the same time, it uses its own displacement to replace the existing deformation, effectively improving the durability of the structure.

[0009] Preferably, rollers for guiding the shielding belt are rotatably connected to the bottom ends of the side frames and the horizontal frame.

[0010] Preferably, two rollers are provided at the bottom end of the side frame, and two rollers are provided at both ends of the horizontal frame. The four rollers are combined to form a rectangular rotation space for the shielding belt.

[0011] Preferably, the two rollers at both ends of the horizontal frame enable clearance between the two sides of the shielding belt and the inner wall of the slot of the horizontal frame.

[0012] Preferably, the roller has a diameter of 10-20 mm.

[0013] Preferably, the outer sides of the side frames and the horizontal frame are covered with outer covers, and movable grooves are provided on the outer covers at positions corresponding to the shielding strips.

[0014] Preferably, the length of the movable groove is smaller than the length of the horizontal frame notch.

[0015] In summary, this application has the following beneficial technical effects:

[0016] A shielding belt tightened by a combination of several rollers is used to shield the slot position of the horizontal frame. The top horizontal section of the shielding belt is flush with the upper end surface of the horizontal frame. The gap around the shielding belt is narrow and uniform. The external cover is used to block the gap position of the shielding belt, further improving the protection effect. At the same time, compared with the elastic structure in the existing technology, there is no gap between the shielding belt and the arc guide rail, and the protective effect will not be lost due to deformation, which largely ensures the safety of the device during operation.

[0023] The following is combined with Figure 1 - Figure 5 This application is described in further detail.

[0024] Example 1:

[0025] A safe moving belt structure for shielding the slot, referring to Figure 1 - Figure 5 , including a side frame 1 and a horizontal frame 2 constituting a partial frame of the bed. The horizontal frame 2 is vertically welded to one side of the top of the side frame 1. The top of the horizontal frame 2 is provided with a slot for the movement of the arc guide rail. The inner side of the slot is slidably embedded with a shielding belt 3 that moves cyclically to form a certain rotation space. The shielding belt 3 is always kept in a tensioned state;

[0026] The shielding strip 3 shields the top view of the notch, and the shielding strip 3 and the upper end surface of the horizontal frame 2 are arranged flush;

[0027] The arc guide rail is fixedly installed on the shielding belt 3 through a connecting piece, and moves synchronously with the shielding belt 3. The connecting piece can be selected from two sheet metal parts, which are placed on the upper and lower sides of the shielding belt 3 respectively. The two are fixedly connected by bolts. The shielding belt 3 is punched with holes corresponding to the bolt positions, and the bolts are set through the shielding belt 3 to ensure that the shielding belt 3 can move with the arc guide rail.

[0028] The bottom end of the side frame 1 and the horizontal frame 2 are both rotatably connected to rollers 4 that guide the shielding belt 3. The power of the shielding belt 3 comes from the displacement of the arc guide rail. When the arc guide rail is displaced, the shielding belt 3 as a whole is cyclically displaced on the roller 4. The shielding belt 3 always maintains the shielding effect on the slot of the horizontal frame 2. Two rollers 4 are set at the bottom end of the side frame 1, and two rollers 4 are set at both ends of the horizontal frame 2. The combination of four rollers 4 makes the shielding belt 3 form a rectangular rotation space. The specific size of the rectangular rotation space can be selected according to actual needs. Its structure does not affect the operation of other parts of the bed while ensuring normal operation. The two rollers 4 at both ends of the horizontal frame 2 make the two sides of the shielding belt 3 and the inner wall of the slot of the horizontal frame 2 fit together. Ears are welded on the side frame 1. The rollers 4 are rotatably connected between the pins and the ear pieces. The rollers 4 in the horizontal frame 2 are set at both ends of the slot of the horizontal frame 2. There is no contact between the shielding belt 3 and the horizontal frame 2, avoiding unnecessary friction.

[0029] The diameter of roller 4 is 10-20mm. The diameter of roller 4 is to ensure the steering requirements of shielding belt 3. The length of roller 4 is slightly larger than the width of shielding belt 3. The width of shielding belt 3 is smaller than the width of slot of horizontal frame 2. The length of shielding belt 3 needs to be ensured to remain taut under the action of four rollers 4. The length of shielding belt 3 is calculated according to the actual position of roller 4.

[0030] The outer sides of the side frames 1 and the horizontal frame 2 are covered with an outer cover 5, and a movable groove 51 is provided on the outer cover 5 at the position corresponding to the shielding belt 3. The length of the movable groove 51 is less than the length of the notch of the horizontal frame 2. The length of the movable groove 51 is set so that the outer cover 5 can shield the upper turning position of the shielding belt 3, thereby effectively preventing debris from falling from the gap position. The horizontal section of the outer cover 5 is attached to the upper side of the horizontal frame 2 to reduce the gap between the horizontal section of the outer cover 5 and the upper end face of the shielding belt 3, thereby increasing the compactness of the device structure and blocking any debris that may exist on the shielding belt 3 to prevent the debris from being transferred to the bed frame by the shielding belt 3.

[0031] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
