DETAILED DESCRIPTION

[0018] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0020] like Figures 1-2 As shown, a preferred embodiment of the present utility model is a lifting device with a locking function, comprising a fixing seat 1, a base 2, a locking rod 3, a connecting seat 4, a handle 5 and a positioning pin 6. The top of the fixing seat 1 is provided with a lifting hole 11, and a locking groove 12 is provided in the fixing seat 1. Both sides of the locking groove 12 are provided with locking holes 13 that are inserted and matched with the locking rod 3. The fixing seat 1 is arranged at the front end of the base 2. Specifically, the fixing seat 1 is perpendicular to the base 2, and the rear end of the base 2 is provided with a positioning seat 21. The head end of the handle 5 is connected to a connecting rod 51, and the head end of the connecting rod 51 rotates with the positioning seat 21. The connection is that a limit seat 22 is provided on the base 2, and a limit hole is provided on the limit seat 22 for the locking rod 3 to slide back and forth, and the locking rod 3 is arranged parallel to the base 2, and the rear end of the locking rod 3 is rotatably connected to the front end of the connecting seat 4, and the rear end of the connecting seat 4 is rotatably connected to the end of the connecting rod 51, and a first latch hole 23 is provided on the base 2 for inserting and cooperating with the positioning pin 6, and a second latch hole 41 is provided on the top of the connecting seat 4 for inserting and cooperating with the positioning pin 6; when the front end of the locking rod 3 passes through the two locking holes 13, the second latch hole 41 is opposite to the first latch hole 23.

[0021] When the utility model is locked, the handle 5 is pulled to make the head end of the connecting rod 51 rotate around the positioning seat 21, so that the end of the connecting rod 51 moves toward the side close to the fixing seat 1 and the end of the connecting rod 51 drives the connecting seat 4 to move close to the side of the fixing seat 1, and the locking rod 3 is rotatably connected with the connecting seat 4. At the same time, under the limiting action of the locking rod 3 in the limiting hole, the connecting seat 4 drives the locking rod 3 to insert into the two locking holes 13 of the fixing seat 1, and then inserts the positioning pin 6 into the first latch hole 23 and the second latch hole 41; when unlocking, first pull out the positioning pin 6 from the first latch hole 23 and the second latch hole 41, and then pull the handle 5 to make the locking rod 3 rotate and connect with the connecting seat 4. The head end of the connecting rod 51 rotates around the positioning seat 21, so that the end of the connecting rod 51 moves toward the side away from the fixing seat 1 and the end of the connecting rod 51 drives the connecting seat 4 to move away from the fixing seat 1, and the locking rod 3 is rotatably connected to the connecting seat 4. At the same time, under the limiting action of the locking rod 3 in the limiting hole, the connecting seat 4 drives the locking rod 3 to be pulled out from the two locking holes 13 of the fixing seat 1; it can be seen that the utility model avoids the mis-locking of the installation device caused by accidental touching of the handle 5 through the setting of the positioning pin 6, thereby ensuring safety in use. At the same time, the lifting device can be locked and unlocked by pulling the handle 5, and the operation is simple.

[0022] Exemplarily, a connecting chain 7 is provided between the end of the handle 5 and the locating pin 6 to ensure that the locating pin 6 is always connected to the entire locating device after the locating device is unlocked, thereby preventing the locating pin 6 from being lost.

[0023] Exemplarily, the locking rod 3 is arranged on the top surface of the base 2. When the front end of the locking rod 3 passes through the two locking holes 13, the handle 5 is located above the connecting rod 51. When the handle 5 is pulled, it is convenient for the operator to observe the movements of various components on the lifting device and to deal with abnormalities in a timely manner.

[0024] Furthermore, the positioning pins 6 are inserted into the first pin hole 23 and the second pin hole 41 in sequence from bottom to top to prevent the connection chain 7 from being entangled with the components on the base 2 .

[0025] Exemplarily, a press-in spring bead 61 is provided on the end side wall of the positioning pin 6. After the positioning pin 6 is inserted into the first pin hole 23 and the second pin hole 41, the positioning pin 6 is effectively positioned to prevent the positioning pin 6 from loosening, thereby improving the safety of use.

[0026] Furthermore, the handle 5 and the connecting rod 51 are integrally formed to enhance overall strength and durability.

[0027] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the various technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
