Abstract
Description
Technical Field
[0001] This application relates to the field of assistive walking equipment technology, and in particular to a wheelchair shock-absorbing placement frame structure. Background Technology
[0002] A wheelchair is an assistive device equipped with wheels to help people walk. It is mainly used by the injured, sick, disabled, and other people who need assistance with movement.
[0003] Traditional wheelchair designs neglect users' need for storage space. In daily use, users often need to carry some daily necessities, such as water bottles, medicines, or small personal items, but traditional wheelchairs lack corresponding storage areas, which causes a lot of inconvenience to users. Utility Model Content
[0004] The purpose of this application is to provide a wheelchair shock-absorbing storage frame structure to improve the problem of where to put daily necessities.
[0005] This application provides a wheelchair shock-absorbing placement frame structure, employing the following technical solution:
[0006] A wheelchair shock-absorbing placement frame structure includes a wheelchair armrest, a connecting plate below the armrest, an installation groove in the connecting plate, a limiting block slidably connected in the installation groove, the top of the limiting block being fixedly connected to the bottom of the wheelchair armrest, and a placement frame being fixedly connected to one end of the connecting plate.
[0007] By adopting the above technical solution, a connecting plate is set under the armrest of the wheelchair, and the limiting block is slidably connected in the mounting groove of the connecting plate. A placement frame is then installed at one end of the connecting plate. In this way, wheelchair users can neatly place water cups or other daily necessities into the placement frame without having to carry them in their hands, which facilitates the travel of wheelchair users.
[0008] Optionally, the connecting plate has an adjustment groove through it, and the lower end of the limiting block has a fixing hole. The fixing hole is threaded with a bolt that passes through the adjustment groove to fix the connecting plate onto the limiting block.
[0009] By adopting the above technical solution, an adjustment groove is opened in the connecting plate, and a fixing hole is opened at the lower end of the limiting block. The connecting plate and the limiting block are connected by bolts. Wheelchair users only need to adjust the position of the bolts in the adjustment groove to adjust the position of the placement frame.
[0010] Optionally, the end of the connecting plate away from the placement frame is provided with an open opening that communicates with the mounting groove.
[0011] By adopting the above technical solution, one end of the connecting plate is set as an open opening. In this way, when the wheelchair user does not want to use the placement frame, the bolts can be loosened and the placement frame can be taken out directly from the open opening of the connecting plate, which is convenient for the wheelchair user.
[0012] Optionally, two receiving slots are correspondingly provided on the inner side wall of the placement frame and on the upper side. An elastic element is fixedly connected in the receiving slot. A connecting block is fixedly connected to the end of the elastic element away from the receiving slot. A locking element is provided at the end of the connecting block away from the elastic element.
[0013] By adopting the above technical solution, two receiving slots are opened on the inner side wall of the placement frame. The elastic element is fixedly connected to the receiving slots, and the connecting block is fixedly connected to the elastic element. A locking device is provided on the connecting block. The elastic element has a telescopic function, which allows cups of different sizes to be placed in the placement frame. The locking device can hold the cups in place to prevent them from falling off.
[0014] Optionally, the card is a semi-circular ring.
[0015] By adopting the above technical solution, the clamp is designed as a semi-circular ring. Cups are typically cylindrical or nearly cylindrical, and the semi-circular ring clamp better matches this shape. Through the arc of the semi-circular ring, the clamp can fit tightly against the outer wall of the cup, thus providing stable support and fixation. When the semi-circular ring clamp holds the cup, the force is distributed along the entire length of the arc, rather than concentrated at a single point. This design makes the force more even, thereby improving the durability and stability of the clamp.
[0016] Optionally, the inner wall of the card is provided with silicone.
[0017] By employing the above technical solution, silicone exhibits excellent frictional properties. When silicone is applied to the inner wall of the clip, the friction between the clip and the cup is significantly increased. This increased friction helps ensure that the clip firmly holds the cup, preventing it from slipping during movement or bumps, thereby improving overall stability. Silicone is soft and elastic; when the inner wall of the clip contacts the cup, it acts as a cushion, reducing pressure and wear on the cup. This helps protect the cup's surface from damage and extends its lifespan.
[0018] Optionally, a rubber layer is provided inside the placement frame and at its bottom.
[0019] By adopting the above technical solution, the rubber layer has good elasticity and resilience. When the placement frame is subjected to external impact or vibration, the rubber layer can absorb part of the impact force and dampen the vibration, thereby protecting the items inside the placement frame from damage. In addition, the rubber layer is soft and will not cause wear or scratches to the items, helping to protect the integrity of the contact surface.
[0020] Optionally, a magnetic element is provided at the bottom of the rubber layer, and the other end of the magnetic element is connected to the bottom of the placement frame.
[0021] By adopting the above technical solution, a magnetic component is provided at the bottom of the rubber layer, and the other end of the magnetic component is connected to the bottom of the placement frame, which can make the rubber layer firmly adhere to the bottom of the placement frame. When the placement frame is subjected to external impact and vibration, the rubber layer will not move.
[0022] In summary, this application includes at least one of the following beneficial technical effects of the wheelchair shock-absorbing placement frame structure:
[0023] 1. A connecting plate is installed under the armrest of the wheelchair, and the limiting block slides in the mounting groove of the connecting plate. A placement frame is then installed on one end of the connecting plate. In this way, wheelchair users can neatly place their water cups or other daily necessities into the placement frame without having to carry them in their hands, which facilitates the travel of wheelchair users.
[0024] 2. Silicone has excellent frictional properties. When silicone is applied to the inner wall of the clip, the friction between the clip and the cup can be significantly increased. This increased friction helps ensure that the clip can firmly hold the cup in place, preventing it from slipping during movement or bumps, thereby improving overall stability.
[0025] 3. The rubber layer has good elasticity and resilience. When the storage frame is subjected to external impact or vibration, the rubber layer can absorb part of the impact force and dampen the vibration, thereby protecting the items inside the storage frame from damage. In addition, the rubber layer is soft and will not cause wear or scratches to the items, helping to protect the integrity of the contact surfaces. Attached Figure Description

Detailed Implementation
[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.
[0031] A wheelchair shock-absorbing placement frame structure, as shown in the reference. Figure 1 The wheelchair assembly includes a wheelchair armrest 1, a connecting plate 2 located below the armrest 1, a mounting groove 21 on the connecting plate 2, a limiting block 3 slidably connected within the mounting groove 21, an adjusting groove 22 extending through the connecting plate 2, and a fixing hole 31 at the lower end of the limiting block 3. A bolt 5, threaded through the adjusting groove 22, is threaded into the fixing hole 31 to fix the connecting plate 2 onto the limiting block 3. The top of the limiting block 3 is fixedly connected to the bottom of the wheelchair armrest 1, and the limiting block 3 and the wheelchair armrest 1 are welded together. A placement frame 4 is fixedly connected to one end of the connecting plate 2. The connecting plate 2 and the placement frame 4 are welded together. The wheelchair user can adjust the position of the placement frame 4 by adjusting the position of the bolt 5 within the adjusting groove 22. An open opening 23, communicating with the mounting groove 21, is located at the end of the connecting plate 2 away from the placement frame 4. When the wheelchair user no longer wants the placement frame 4, they can remove it from the open opening 23 of the connecting plate 2.
[0032] Reference Figure 2Two receiving slots 41 are correspondingly formed on the inner side wall and upper part of the placement frame 4. An elastic element 6, which is a spring, is fixedly connected to each receiving slot 41. The receiving slots 41 and the elastic element 6 are welded together. A connecting block 61 is fixedly connected to the end of the elastic element 6 away from the receiving slots 41. The elastic element 6 and the connecting block 61 are welded together. A locking element 62 is provided at the end of the connecting block 61 away from the elastic element 6. The outer wall of the locking element 62 is welded to the connecting block 61. The elastic element 6 has a telescopic function, allowing cups of different sizes to be placed in the placement frame 4. The locking element 62 can hold the cup in place, preventing it from falling. The locking element 62 is designed as a semi-circular ring. The locking element 62 can fit tightly against the outer wall of the cup, providing stable support and fixation. When the semi-circular ring locking element 62 holds the cup, the force is distributed along the entire length of the arc, rather than concentrated at a single point. This design makes the force more even, thereby improving the durability and stability of the locking element 62. The inner wall of the clip 62 is provided with silicone 63, which can significantly increase the friction between the clip 62 and the cup. This increased friction helps ensure that the clip 62 can firmly hold the cup in place, preventing it from slipping off during movement or bumps, thereby improving overall stability.
[0033] Reference Figure 3 A rubber layer 71 is provided inside the placement frame 4 and at its bottom. This layer absorbs some of the impact force and dampens vibration, thus protecting the items inside the placement frame 4 from damage. A magnetic element 72, which is a magnet, is located at the bottom of the rubber layer 71. The other end of the magnetic element 72 is connected to the bottom of the placement frame 4. The magnetic element 72 is welded to the bottom of the placement frame 4, ensuring that the rubber layer 71 is firmly attached to the bottom of the placement frame 4 and will not move.
[0034] The implementation principle of this embodiment is as follows: the bolt 5 moves within the adjusting groove 22 of the connecting plate 2, causing the position of the placement frame 4 to shift. When the wheelchair user no longer wishes to use the placement frame 4, it can be removed from the opening 23 of the connecting plate 2. Different sized cups can be placed by the contraction of the elastic element 6. The semi-circular silicone 63 clip 62 ensures that the clip 62 fits tightly around the cup, so the wheelchair user does not need to worry about the cup moving or slipping during use.
[0035] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
