In order to explain technical contents, structural features, and effects achieved by the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.
As shown in fig. 1 and 2, the foldable wheelchair support 100 of the present invention is applied to a wheelchair, and includes a wheelchair support 2, a locking mechanism 3 and a lock releasing operation mechanism 1, wherein the wheelchair support 2 is of a foldable structure, the locking mechanism 3 is disposed on the wheelchair support 2 and locks the unfolded state of the wheelchair support 2, and the lock releasing operation mechanism 1 is disposed on the upper end of a backrest rod 21 of the wheelchair support 2 and drives the locking mechanism 3 to unlock.
The release operating mechanisms 1 are respectively arranged on both sides of the upper end of the backrest rod 21. Because the back rod 21 needs to be held by hands and then folded forward when folded, the lock releasing operation mechanisms 1 are arranged on two sides of the upper end of the back rod 21, so that the lock releasing can be directly pressed before folding, the actions can be consistent, and the operation convenience is improved.
Specifically, as shown in fig. 2 and 3, the release operation mechanism 1 includes a release button 11, a fixing member 12 and a flexible connecting member 13, wherein the release button 11 is slidably disposed at an upper end of the backrest rod 21, specifically, slidably along a length direction of the backrest rod 21. When the lock release button 11 is fully extended out of the upper end of the backrest rod 21, the lock release button 11 is limited by the backrest rod 21 and prevented from being separated from the backrest rod 21. The fixing piece 12 is fixed on the unlocking button 11; one end of the flexible connecting piece 13 is connected to the locking mechanism 3, and the flexible connecting piece 13 is basically a locking pin connected to the locking mechanism 3, and the locking pin can be inserted into or separated from a locking hole to realize the locking or unlocking function; the fixing piece 12 is connected with the other end of the flexible connecting piece 13 and can adjust the tension degree of the flexible connecting piece 13; the release button 11 is slidably disposed to drive the flexible connecting member 13 through the fixing member 12 to unlock the locking mechanism 3. The fixing member 12 includes a first connecting member 121 and a second connecting member 122, the first connecting member 121 is located on the release button 11, the second connecting member 122 is movably disposed relative to the first connecting member 121, and the flexible connecting member 13 is connected to the second connecting member 122. The first connecting piece 121 is of a tubular structure, the inner wall of the inner hole 121a is provided with threads, and the second connecting piece 122 is sleeved in the first connecting piece 121, and the outer wall of the first connecting piece is provided with threads so as to be in threaded connection with the first connecting piece 121. By moving the position of the second connecting member 122, the flexible connecting member 13 is driven, so that the tightness of the flexible connecting member 13 can be adjusted. Through threaded connection, the adjustable support can be adjusted at any time, can also be mutually fixed without displacement when not adjusted, and effectively improves the convenience of adjustment and use.
Referring to fig. 2 and 3, the end surface of the second connecting member 122 is provided with a connecting hole 122a, and the connecting hole 122a is a hexagonal counterbore. The release button 11 is provided with a through hole 11a, and the connecting hole 122a corresponds to the through hole 11a and is communicated with the outside through the through hole 11 a. The second connecting member 122 can be screwed by a tool through the connecting hole 122a, thereby easily achieving the purpose of adjustment. By providing the through hole 11a, the adjustment tool can directly reach the connection hole 122a from the through hole 11a, and therefore, the release button 11 does not need to be detached, and the convenience of adjustment is improved. The side wall of the first connecting member 121 is provided with an opening groove 121b extending along the central axis direction thereof, and the opening groove 121b is communicated with the inside so as to allow the flexible connecting member 13 to pass through.
Referring to fig. 2 and 3, the release operating mechanism 1 further includes an elastic reset member 14 for resetting the release button 11. The elastic restoring member 14 is a compression spring, one end of which abuts against the release button 11 and the other end of which abuts against the backrest rod 21.
Referring to fig. 2 and 3, the release operating mechanism 1 further includes a guide wheel 15, the guide wheel 15 is disposed in the backrest rod 21, and the flexible connecting member 13 is wound around the guide wheel 15 from one side of the guide wheel 15 opposite to the fixing member 12 to the other side of the guide wheel 15 and connected to the fixing member 12. The flexible connecting piece 13 of the utility model is a steel wire or a rope.
In summary, when unlocking, only the lock release button 11 needs to be pressed to make the lock release button 11 drive the fixing member 12 to move downwards, the fixing member 12 drives the end portion of the flexible connecting member 13 to move downwards, and since the flexible connecting member 13 is wound on the guide wheel 15 and the guide wheel 15 rotates, the other end of the flexible connecting member 13 moves upwards, that is, the flexible connecting member 13 pulls the locking pin of the locking mechanism 3 to move, so that the locking mechanism 3 is unlocked. When the lock release button 11 is released after the lock is released, the lock release button 11 can be reset under the elastic force of the elastic reset piece 14.
After a period of use, the flexible connecting member 13 becomes loose due to long-term stress and length increase, so that a hexagonal key can be used to pass through the through hole 11a to be inserted into the connecting hole 122a, and then the second connecting member 122 is screwed, so that the second connecting member 122 moves downward relative to the first connecting member 121, thereby tightening the flexible connecting member 13, and the lock release button 11 can drive the locking pin to move more easily.
Compared with the prior art, because the utility model discloses a set up mounting 12 on the release button 11, and make flexible connectors 13 one end with fixed connection utilizes mounting 12 is adjustable flexible connectors 13's rate of tension, thereby makes flexible connectors 13 can be taut after using one section, and then makes release button 11's operation stroke shorter, makes the release become more sensitive, and the release is effectual, improves the convenience of operation. In addition, when the lock release button 11 and the flexible connecting piece 13 are assembled, the flexible connecting piece 13 does not need to be tensioned and then assembled, the flexible connecting piece 13 only needs to be connected in a conventional state, and finally the fixing piece 12 is adjusted, so that the assembly is more convenient.
