Technical Field

[0001] This utility model relates to the field of handrail technology, specifically a movable handrail. Background Technology

[0002] During CT, PET / CT, and MRI examinations, wooden ladders are usually provided next to the examination bed to facilitate the patient's access to and from the bed. These wooden ladders typically have three tiers and usually lack handrails. Elderly individuals, those with unsteady gait, and those with mobility impairments may experience balance issues when going up and down the ladders, posing a risk of falls. Additionally, the examination bed is relatively narrow, and elderly individuals, those with mobility impairments, or those wearing thick clothing in winter may also experience falls when getting up or down from the examination bed.

[0003] In the existing technology, handrails used in medical examinations are usually placed directly on the ground, which results in insufficient stability and easy displacement, thus affecting the normal use of the handrails. At the same time, when the handrails are displaced, they are prone to causing falls for the elderly and people with mobility impairments, and it is also difficult to move the handrails by hand. Utility Model Content

[0004] The purpose of this invention is to provide a movable handrail to solve the problem of insufficient stability of handrail placement mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a movable handrail, comprising: a first handrail, a second handrail, and a support column. The second handrail is provided on the outer side of the end of the first handrail. The ends of the first and second handrails that are far apart from each other are connected to the support column. A moving wheel is installed at the bottom of the support column. A connecting block is welded to the inner side of the support column. A groove is formed on the inner side of the connecting block. A connecting plate is welded to the bottom of the connecting block. A connecting shaft is connected between the two connecting plates.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 , Figure 3 and Figure 4It is understood that the present invention provides a technical solution: a movable handrail, comprising: a first handrail 1, a second handrail 2 and a support column 3, wherein the second handrail 2 is provided on the outer side of the end of the first handrail 1, and the support column 3 is connected to the ends of the first handrail 1 and the second handrail 2 that are far apart from each other, wherein a movable wheel 4 is installed at the bottom end of the support column 3, and a connecting block 5 is welded to the inner side of the support column 3, wherein a groove 6 is provided on the inner side of the connecting block 5.

[0017] The movable armrest has a recessed groove 6 for storing the foot pedal 10.

[0018] exist Figure 1 and Figure 2 In the middle section: a connecting plate 7 is welded to the bottom of the connecting block 5, a connecting shaft 8 is connected between the two connecting plates 7, a stop block 9 is rotatably connected to the outside of the connecting shaft 8, a foot pedal 10 is connected to the top of the stop block 9, a plastic suction cup housing 11 is connected to the bottom of the two connecting plates 7, a suction cup body 12 is connected to the bottom of the plastic suction cup housing 11, a valve 19 is connected to the top of the plastic suction cup housing 11, and the valve 19 communicates with the inside of the suction cup body 12.

[0019] The movable handrail and the abutment block 9 can squeeze the plastic suction cup housing 11 to create negative pressure inside the suction cup body 12, so that the suction cup body 12 can adhere to the ground.

[0020] exist Figure 1 , Figure 3 and Figure 4 In the middle: the first handrail 1 and the second handrail 2 are set at different heights on the inner side of the two sets of support columns 3. Both the first handrail 1 and the second handrail 2 are made of stainless steel.

[0021] The movable handrails, with the first handrail 1 and the second handrail 2 made of stainless steel, are easy to clean and not easily damaged. The two sets of first handrails 1 and second handrails 2 at different heights are convenient for examiners of different heights.

[0022] In practice, handrails are commonly used during medical examinations. Traditional handrails are not stable enough and are prone to displacement, which can easily cause falls, especially for the elderly and those with mobility issues. When using handrails, the first handrail 1 and the second handrail 2 can be easily and conveniently moved to a designated position beside the examination bed using the casters 4 and support columns 3. At this time, the two sets of pedals 10 can be stepped on downwards away from the corresponding connecting blocks 5. When the pedals 10 move, they can drive the abutment block 9 to move. When the abutment block 9 moves, it can be rotated through the connecting shaft 8. At this time, the pedals 10 can be rotated out of the groove 6. When the abutment block 9 rotates, its bottom surface can press against the top surface of the plastic suction cup housing 11, so that the plastic suction cup housing 11 can slightly push the suction cup body 12. Simultaneously, the top surface of the plastic suction cup housing 11 undergoes compression deformation, allowing the bottom of the suction cup body 12 to adhere to the ground. When the abutment block 9 and the foot pedal 10 rotate to 90°, the bottom of the suction cup body 12 can adhere tightly to the ground and generate negative pressure, allowing the suction cup body 12 to adhere to the ground. This enables the first handrail 1, the second handrail 2, and the support column 3 to be stably placed in the designated position. At this time, elderly people and those with mobility impairments can place their hands on the first handrail 1 and the second handrail 2 and then go up and down the inspection bed via the wooden steps. After releasing the foot pedal 10, the abutment block 9 no longer compresses the top of the plastic suction cup housing 11. At this time, the valve 19 can be manually opened, allowing outside air to enter the interior of the suction cup body 12 through the valve 19. The negative pressure of the suction cup body 12 disappears, and the handrails can be moved.

[0023] See Figures 1-4 It can be seen that the suction effect of the suction cup body 12 can improve the overall stability of the first handrail 1, the second handrail 2 and the support column 3, making it less likely for the first handrail 1, the second handrail 2 and the support column 3 to shift in position, which can improve the safety of the elderly and people with mobility impairments when using the handrail.

[0024] exist Figure 1 and Figure 4 In the middle: the interior of the second handrail 2 is provided with a sliding groove 13, and the bottom of the sliding groove 13 is provided with a limiting groove 14.

[0025] The movable handrail and the limiting groove 14 can limit the extension distance of the telescopic rod 15.

[0026] exist Figure 1 and Figure 3 In the middle: The first handrail 1 is connected to a telescopic rod 15 at one end near the second handrail 2. A threaded post 16 is connected to the lower end of the telescopic rod 15. A rubber stop 17 is connected to the bottom end of the threaded post 16. A threaded ring 18 is threadedly connected to the outer side of the threaded post 16. The telescopic rod 15 is made of stainless steel.

[0027] The movable handrail can extend the overall grip length of the first handrail 1 and the second handrail 2 by adjusting the extension distance of the telescopic rod 15.

[0028] In practice, when using the handrail, first loosen the two sets of threaded rings 18, then pull the support column 3 connected to the first handrail 1 away from the second handrail 2. This allows the first handrail 1 to drive the telescopic rod 15 to slide inside the slide groove 13, and the telescopic rod 15 to drive the threaded column 16 and the rubber stop 17 to move. The threaded column 16 can move along the limiting groove 14. At this time, the first handrail 1 and the second handrail 2 gradually move away from each other. When the telescopic rod 15 slides out of the slide groove 13 to the designated position, the two sets of threaded rings 18 can be tightened, so that the top of the threaded ring 18 can be pressed and fixed to the bottom of the second handrail 2, making it difficult for the telescopic rod 15 and the first handrail 1 to shift position. The rubber stop 17 at the bottom of the threaded column 16 can effectively prevent people from gripping the threaded column 16 and causing hand injuries.

[0029] See Figure 1 , Figure 3 and Figure 4 It can be seen that by adjusting the distance between the first handrail 1 and the second handrail 2, the telescopic rod 15 can extend the grip length of the first handrail 1 and the second handrail 2, so that the inspector can use it according to the actual situation. When not in use, the telescopic rod 15 can be retracted into the second handrail 2, thereby reducing the overall space area for the handrail and making it easier to place and store the handrail later.

[0030] In summary, when using this movable handrail, the first handrail 1 and the second handrail 2 can be easily and conveniently moved to a designated position on the side of the examination bed via the moving wheels 4 and the support column 3. At this time, the two sets of foot pedals 10 can be stepped on downwards away from the corresponding connecting blocks 5. Through the adsorption effect of the suction cup body 12, the stability of the first handrail 1, the second handrail 2, and the support column 3 can be improved, making it less likely for the first handrail 1, the second handrail 2, and the support column 3 to shift in position. This can improve the safety of the elderly and people with mobility impairments when using the handrail. By adjusting the distance between the first handrail 1 and the second handrail 2, the telescopic rod 15 can extend the grip length of the first handrail 1 and the second handrail 2, making it convenient for the examiner to use according to the actual situation. When not in use, the telescopic rod 15 can be retracted into the second handrail 2, thereby reducing the overall space required for the handrail and facilitating its later placement and storage.
