In addition, the pushing spring 212 arranged in the sleeve 211 makes the pushing column 207 have the tendency of moving outwards under the condition that the rotating block 208 is not pressed, and the limiting block 203 is driven to keep clamped in the limiting groove 103 through the transmission relationship, so that the handrail column 201 keeps a fixed state under the normal state.
The armrest unit 2 further includes a sleeve limiting groove 213 disposed on an inner side surface of the sleeve 211, a jacking block 214 disposed on the sleeve limiting groove 213, and an engaging block 215 disposed on the push post 207.
In this embodiment, in order to prevent the pushing force of the rotating block 208 from being maintained during the moving of the pushing column 207, the engaging block 215 is disposed on the pushing column 207 for engaging with the lifting block 214, the lifting block 214 is disposed at a position close to the opening direction of the sleeve 211 on the top surface of the inner side of the sleeve limiting groove 213, and a temporary groove body for engaging with the engaging block 215 is formed with the inner side surface of the sleeve limiting groove 213, and when the pushing column 207 is pushed inward, the engaging block 215 slides into the temporary groove body by a sliding action, so that the pushing column 207 is not pushed outward by the pushing spring 212.
The armrest unit 2 further includes an arc-shaped groove 216 disposed on the transmission post 209 and used for mounting the pushing post 207, a pushing post engaging block 217 disposed on the pushing post 207, and an arc-shaped limiting groove 218 disposed on an inner side surface of the arc-shaped groove 216 and used for mounting the pushing post engaging block 217.
In this embodiment, the whole of the jacking block 214 is of a ladder platform structure, the contact surface of the oblique edge of one side of the engaging block 215 and the jacking block 214 is of an arc structure, when the armrest column 201 needs to be fixed again, the engaging block 215 and the jacking block 214 can be disengaged from the engaging action only by rotating the rotating block 208, and after the pushing column 207 moves outwards, the rotating block 208 is rotated again in the opposite direction, so that the engaging block 215 can be returned to the position below the jacking block 214 again in a squeezing manner.
In addition, in the process of rotating the pushing column 207, the pushing column engaging block 217 is driven to rotate in the arc-shaped limiting groove 218, and such design enables the pushing column 207 to freely rotate on the transmission column 209 and simultaneously drive the transmission column 209 to translate.
The armrest unit 2 further includes a latch groove 219 disposed on the pushing post 207 for mounting the latch 215, a spring plate 220 disposed on the latch 215, and a latch spring 221 sleeved on the latch 215 for lifting up the spring plate 220.
In this embodiment, in order to make the engaging block 215 retract during the pressing process to facilitate the engaging with the lifting block 214 and the releasing process, the pushing column 207 is provided with the engaging block groove 219 for installing the engaging block 215 to retract into the engaging block groove 219 during the pressing process, and the engaging block spring 221 is provided on the inner bottom surface of the engaging block groove 219 for lifting up the engaging block 215 by lifting up the spring plate 220, so that it can be ejected without being pressed by the outside and is locked with the lifting block 214.
The armrest unit 2 further includes a spring plate groove 222 provided on an inner side surface of the engagement block groove 219 and for mounting the spring plate 220.
In this embodiment, in order to prevent the engaging block 215 from being separated from the engaging block groove 219 during the ejection process, the spring plate grooves 222 are respectively provided on the left and right sides of the engaging block groove 219 to engage with the spring plate 220 having a length slightly longer than the opening length of the engaging block groove 219, so that the movable range of the engaging block 215 does not exceed the notched range of the spring plate groove 222.
The armrest unit 2 further comprises a fixing hole 223 provided on the driving post 209, and a fixing post 224 provided on the inner side of the armrest post cavity 204 and inserted into the fixing hole 223.
In this embodiment, the driving post 209 is too long, which may cause bending due to vertical pulling force during force transmission, so that the stopper 203 may not be completely removed from the stopper groove 103 when the pushing post 207 is pushed to a specified position, and then the fixing post 224 is inserted into the fixing hole 223 disposed on the driving post 209, so that the driving post 209 maintains a vertical state during translation.
The armrest unit 2 further includes a support groove 225 disposed on the driving block 210, and a support insertion post 226 disposed on an inner side surface of the armrest post cavity 204 and used for inserting and fixing the support groove 225.
In this embodiment, the support insertion post 226 is inserted into the support slot 225, so that the transmission block 210 keeps moving horizontally during the translation process, and further cooperates with the fixing post 224 to fix the transmission post 209, and so that the limiting block 203 also keeps moving horizontally.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
