Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

As shown in fig. 1 to 7, the present invention provides a lifting column convenient for maintenance, which includes a control system, an outer cylinder 10, an inner cylinder 20, a driving device 30 and a locking mechanism 40. The inner cylinder 20 is installed inside the outer cylinder 10, and the inner cylinder 20 can be lifted up and down inside the outer cylinder 10 by the piston rod 31 of the driving device 30. The inner cylinder 20 comprises a guide section 21 and an anti-collision section 22 arranged on the guide section 21, and the anti-collision section 22 is bonded with the guide section 21 through glue or other methods. A plurality of slots 221 are circumferentially formed on the outer peripheral surface of the anti-collision section 22. An infrared sensor 222 is mounted on the upper portion of the crash section 22, and the infrared sensor 222 can detect whether a vehicle is not braked near the lifting column and continue to run. The infrared sensor 222 is electrically connected to the control system.

A locking mechanism 40 is included that locks the position of the bumper segment 22. Specifically, the locking mechanism 40 includes a fixed plate 41, a first through hole 411 is longitudinally formed in the fixed plate 41 for receiving the bump protection segment 22, and the fixed plate 41 is fixedly connected with the ground 80 through a bolt 44. The inner circumferential surface of the fixed disk 41 is opened with a plurality of receiving grooves 42 extending outward, and preferably, the plurality of receiving grooves 42 are uniformly arranged in the circumferential direction of the fixed disk 41. The plurality of receiving grooves 42 are disposed in one-to-one correspondence with the plurality of card slots 221.

Each receiving groove 42 is provided therein with a locking assembly 50, and the locking assembly 50 includes a latch 51, a spring 52 and a shutter 53. The latch 51 and the spring 52 are both disposed in the receiving groove 42, the spring 52 is located between the latch 51 and the groove wall of the receiving groove 42, one end of the spring 52 is connected with the latch 51, and the other end is connected with the fixed tray 41. The spring 52 is always in a compressed state, so that the latch 51 has a tendency to move away from the receiving groove 42. The baffle 53 is longitudinally arranged in the first through hole 411, guide rails 43 are arranged on two sides of the baffle 53, the guide rails 43 are fixedly connected with the fixed disc 41, and the baffle 53 can slide longitudinally on the inner circumferential surface of the fixed disc 41 under the guiding action of the guide rails 43. The upper portion of the shutter 53 abuts against the latch 51 to prevent the latch 51 from leaving the receiving groove 42. The second through hole 531 is transversely formed at the lower portion of the blocking plate 53, so that the latch 51 can pass through the second through hole 531, the blocking plate 53 and leave the accommodating groove 42 after the blocking plate 53 is lifted.

The lifting column has at least two working states. In the first operating state, the lifting column is used normally as a common lifting column, and the anti-collision section 22 does not contact with the baffle 53 in the lifting process. The piston rod 31 controls the inner cylinder 20 to ascend and descend, so that the inner cylinder 20 extends out of the ground 80 or is hidden under the ground 80, and the vehicle passing is controlled. In the second working state, the vehicle is not braked in time before running to the lifting column, and the infrared sensor 222 on the anti-collision segment 22 detects that the vehicle does not stop running nearby, and transmits a signal to the control system. The control system controls the piston rod 31 to extend, and during the extension process of the piston rod 31, the collision-prevention section 22 contacts with the baffle plate 53 and drives the baffle plate 53 to ascend together. When the baffle 53 rises to a certain height, one end of the latch 51 will pass through the second through hole 531 of the baffle 53 and be inserted into the latch groove 221 of the bump guard 22 under the action of the spring 52, and the other end will still be located in the receiving groove 42. The impact segment 22 is now indirectly connected to the ground 80 by the locking mechanism 40. When the vehicle hits the impact-resistant section 22, in addition to overcoming the adhesive force between the impact-resistant section 22 and the guide section 21, the acting force generated by the fixed connection of the locking mechanism 40 to the ground 80 needs to be overcome, thereby enabling the intercepting effect of the entire lifting column to be better. In addition, when a vehicle collides the anti-collision section 22, the guide section 21 and the anti-collision section 22 can be disconnected from each other for the anti-collision section 22 is damaged by the vehicle collision, and other components in the guide section 21, the piston rod 31 and the lifting column cannot be damaged, so that a maintenance worker only needs to replace the anti-collision section 22 and the locking mechanism 40, and the maintenance is convenient.

In one embodiment, the number of the receiving grooves 42 of the fixed platter 41 is at least three. Since the receiving grooves 42 are uniformly arranged along the circumferential direction of the fixed disk 41 and are disposed in one-to-one correspondence with the slots 221, at least three slots 221 are correspondingly formed on the outer circumferential surface of the anti-collision section 22. The locking mechanism 40 thus provides a snap-lock locking of the bump stop 22 in at least three directions, resulting in a stable triangular configuration.

The design of the three receiving slots 42 is such that no matter which direction the vehicle hits the bump stop 22, the bump stop 22 will not easily disengage from the mounting plate 41, as compared to a single or two receiving slots 42, thereby further improving the vehicle arresting effect of the entire lifting column.

In one embodiment, an electromagnet 23 is fixedly arranged at the top of the guide section 21, a magnet 24 is fixedly arranged at the bottom of the collision avoidance section 22, and the electromagnet 23 can attract the magnet 24 after being electrified. In the first working state, the lifting column is normally used as a common lifting column, the electromagnet 23 is in an electrified state, and the electrified electromagnet 23 and the magnet 24 attract each other. In the second operating state, the electromagnet 23 is de-energized and no force is generated between it and the magnet 24.

When the anti-collision section 22 and the guide section 21 are not adhered stably during installation, or when rainwater infiltrates to cause poor adhesion. The design of the electromagnet 23 enables a relatively stable connection to be maintained between the impact protection section 22 and the guide section 21 at all times.

In one embodiment, the top of the guiding section 21 is provided with a dust guard 60, and the dust guard 60 is located between the outer cylinder 10 and the guiding section 21 and detachably connected with the guiding section. Since vehicles are often traveling on the ground 80 near the lifting columns, there is a greater amount of dust in the air. The design of the dust guard 60 greatly reduces the ingress of dust into the lifting column, thereby preventing dust from affecting the operation of the control system and the drive means 30. The dust guard 60 can be conveniently replaced by the detachable connection mode. In the second operating state, the dust guard 60 rises with the inner cylinder 20 and contacts the shutter 53.

In one embodiment, the spring 52 is a compression spring. The latch 51 has a tendency to move away from the receiving groove 42 by the compression spring.

In one embodiment, the upper portion of the impact segment 22 has a plurality of warning lights 70. The warning lamp 70 continuously flickers to remind the driver of limiting the traffic ahead, so that the occurrence of accidental collision accidents is reduced, and the life safety of the driver is guaranteed.

In one embodiment, a plurality of warning lights 70 are circumferentially disposed on the outer periphery of the impact segment 22 at least two different heights from the ground 80. The warning lights 70 with different heights flash alternately to have layered visual effect, so that the attention of the driver can be better attracted, thereby further reducing the occurrence of accidents and ensuring the life safety of the driver.

A working method of a lifting column is applied to the lifting column convenient to maintain, and comprises the following steps:

s10: when the infrared sensor 222 detects that the vehicle does not stop running nearby, the piston rod 31 drives the inner cylinder 20 to ascend, and the inner cylinder 20 drives the dust-proof plate 60 to ascend to contact with the baffle 53.

S20: the dust-proof plate 60 pushes the shutter 53 to ascend together.

S30: the shutter 53 rises to a certain height. One end of the latch 51 is ejected out of the receiving groove 42 by the spring 52, passes through the second through hole 531, and then extends into the latch groove 221 of the bump stop 22, and the other end is still located in the receiving groove 42. The impact segment 22 is indirectly coupled to the ground 80 by the locking mechanism 40.

S40: the crash section 22 of the inner tube 20 is struck by the vehicle, is separated from the guide section 21, and damages the lock mechanism 40 under the impact of the vehicle.

S50: the service person replaces the new bump stop 22 and locking mechanism 40.
