Detailed Description

Further advantages and effects of the present utility model will become readily apparent to those skilled in the art from the disclosure herein, by referring to the accompanying drawings and the preferred embodiments. The utility model may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present utility model. It should be understood that the preferred embodiments are presented by way of illustration only and not by way of limitation.

It should be noted that the illustrations provided in the following embodiments merely illustrate the basic concept of the present utility model by way of illustration, and only the components related to the present utility model are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complicated.

As shown in fig. 1-4, the present application provides a locking mechanism comprising a side plate 9, a bracket 10 and a locking assembly. The bracket 10 is fixedly connected with a rotating shaft 91. The side plate 9 is rotatably connected to the rotation shaft 91. The locking assembly comprises a limiting block 7 and a limiting pin 8. The limiting block 7 is fixedly sleeved on the rotating shaft 91. The limiting block 7 is provided with a limiting groove 71. The limit groove 71 is formed by recessing the outer wall of the limit block 7 inward in the radial direction. The limit pin 8 is fixedly connected to the side plate 9 and is embedded in the limit groove, and when the side plate 9 rotates from the locked state to the unlocked state around the rotation shaft 91, the limit pin 8 slides between the end surfaces of the limit groove 71. This application sets up the spacing groove and replaces the locking hole, and the spacer pin only needs one side laminating to the spacing groove at the rotatory in-process of unblock of curb plate, does not need the higher locking hole structure of precision, and the locking clearance is little, can optimize rocking and abnormal sound of handrail, and structural design is small and exquisite, easily integrated, and is low to arranging the space requirement. Preferably, the locking mechanism may be mounted on the armrests of the seat or on the seat back.

The locking assembly further comprises a first locking block 6. The first lock block 6 is rotatably provided on the side plate 9. The first locking piece 6 is provided with the lug 61 near stopper 7 one side, and stopper corresponds lug 61 department and is provided with matched recess 72. The first locking piece 6 can be rotated until the projection 61 is engaged with the groove 72 or the projection 61 is disengaged from the groove 72. When the projection 61 is engaged with the groove 72, the side plate 9 cannot be rotated about the rotation shaft 91, and the side plate 9 is kept in the locked state, and when the projection 61 is disengaged from the groove 72, the side plate 9 can be rotated about the rotation shaft, and the side plate is kept in the unlocked state.

The first lock block 6 is rotatably connected at one end to the side plate 9 and is provided at the other end with a second lock block 5. The second lock block 5 is rotatably connected to the side plate 9. The second lock block 5 is provided with a boss 51 on the peripheral side. The second locking piece 5 can be rotated until the boss 51 approaches and presses the first locking piece 6, the boss 51 being the first locking piece 6 in place. When the boss 51 presses the first lock block 6, the rotational tendency of the first lock block 6 is restricted by the boss 51 and cannot be rotated. Conversely, when the boss 51 is away from the first lock block 6, the first lock block 6 can rotate around its own axis. The connection of the second locking block 5 and the side plate 9 is provided with a spring 4. The rotation that this application set up the spring and restrict second locking piece 5 for second locking piece 5 extrudees first locking piece 6 all the time under the locking state, guarantees first locking piece 6 block to stopper 7, and curb plate 9 can't revolute the rotation of rotation axis.

The locking assembly further comprises a pull cable 3. One end of the inhaul cable 3 is fixedly connected to a non-axial position of the second locking block 5. In this way, the guy cable 3 can drive the second locking block 5 to rotate around the axis of the guy cable, so that the boss 51 on the second locking block 5 does not squeeze the first locking block 6 any more.

The locking assembly further comprises an unlocking synchronous support 2 and an unlocking pull belt 1, and one end, away from the second locking block 5, of the inhaul cable 3 is connected to the unlocking synchronous support 2. One end of the unlocking pull strap 1 is connected to the unlocking synchronous bracket 2, and the other end of the unlocking pull strap penetrates out of the side plate 9. The application sets up unblock synchronous support 2, unblock stretching strap 1 and cable 3 for can accomplish the unblock of curb plate through pulling the unblock stretching strap from the curb plate outside, thereby adjust the gesture of curb plate, the unblock mode is simple swift. The specific structure of the unlocking synchronous support 2 can be referred to the existing unlocking synchronous support, and will not be described in detail here. It is worth noting that, this application is provided with structures such as two sets of guy ropes 3, second locking piece 5 and first locking piece 6 on curb plate 9 for locking subassembly's atress distributes evenly, and the structure is reliable.

The application also provides a handrail, including handrail body and locking mechanism as described above, locking mechanism installs on the handrail body.

The application also provides a vehicle comprising a vehicle body and an armrest as described above, the armrest being mounted on the vehicle body.
