Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Second, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures or characteristics that may be included in at least one implementation manner of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or selectively exclusive embodiments from other embodiments.

[0028] Thirdly, the present utility model is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present utility model, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples, which should not limit the protection scope of the present utility model here. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0029] Referring to Figures 1-5 , the present utility model provides an electric hoist crane controller, including:

[0030] The control unit 100 includes a controller main body 101. A button group 102 is provided on one side of the controller main body 101. The button group 102 is used for inputting instructions. An antenna 103 is provided on the top of the controller main body 101. The antenna 103 is used for sending out the instructions processed by the controller main body 101. A display screen is provided on the controller main body 101. The display is used for displaying the input data. The button group 102 is composed of a lifting button, a data input button and a confirmation button;

[0031] The assembling unit 200 includes a U-shaped block 201. The U-shaped block 201 is fixedly installed on the inner wall of the controller main body 101. A connecting rod 202 is slidably installed on one side of the U-shaped block 201. A splitting component 203 is provided at the top of the connecting rod 202. A rectangular block 207 is slidably inserted into the interior of the U-shaped block 201. A back plate 204 is fixedly installed on one side of the rectangular block 207. Magnets 205 are fixedly installed on the outer wall of the connecting rod 202 and inside the back plate 204. The two magnets 205 are magnetically installed. The magnets 205 fix the four corners of the back plate 204 to prevent warping. A sealing groove is opened on the side wall of the controller main body 101. A sealing strip 206 is slidably installed in the sealing groove of the controller main body 101. The sealing strip 206 improves the sealing performance and prevents water from entering the interior of the controller main body 101, facilitating use outdoors. A plug rod 208 is fixedly installed on one side of the connecting rod 202. The plug rod 208 penetrates through the U-shaped block 201 and is slidably inserted into the interior of the rectangular block 207.

[0032] Wherein, a sliding groove 209 is opened on one side of the U-shaped block 201. The U-shaped block 201 is slidably installed with the connecting rod 202 through the sliding groove 209. The sliding groove 209 can guide the sliding of the connecting rod 202 to avoid the phenomenon of sliding misalignment of the connecting rod 202.

[0033] Further, a circular hole is formed inside the U-shaped block 201, and the insertion rod 208 is slidably inserted into the U-shaped block 201 through the circular hole. The circular hole inside the U-shaped block 201 enables the insertion rod 208 to pass through the U-shaped block 201, facilitating the limiting of the rectangular block 207 by the insertion rod 208.

[0034] Further, a circular groove is formed inside the rectangular block 207, and the rectangular block 207 is slidably inserted into the insertion rod 208 through the circular groove. When the insertion rod 208 is inserted into the rectangular block 207, the position of the rectangular block 207 can be restricted, thereby fixing the position of the back plate 204 and realizing the combined installation of the back plate 204 and the controller body 101.

[0035] Further, the splitting component 203 includes a round rod 203a. The round rod 203a is fixedly installed at the top of the connecting rod 202. A spring 203b is sleeved on the outer wall of the round rod 203a. A limiting piece is fixedly installed at the top of the round rod 203a. The top end of the spring 203b is fixedly installed with the limiting piece, and the bottom end of the spring 203b is fixedly installed with the controller body 101. Pressing to control the sliding of the connecting rod 202 through the round rod 203a causes the insertion rod 208 to be pushed out of the rectangular block 207, and at the same time, it will also drive the two mutually attracting magnets 205 to split.

[0036] Furthermore, a circular hole slot is formed in the top wall of the controller body 101, and the round rod 203a is slidably inserted into the top wall of the controller body 101 through the circular hole slot. The circular hole chute can well guide the sliding of the round rod 203a and prevent the problem of sliding misalignment of the round rod 203a.

[0037] During use, first, when controlling the hoist, lift and lower data is input by pressing the button group 102. After being processed by the controller body 101, it is sent by the antenna 103 to control the hoist to lift and lower.

[0038] The button group 102 includes data input buttons, lift and lower buttons, and confirmation buttons. And a display is equipped on the controller body 101. Specifically, during work, first, specific lift and lower data is input through the data input buttons, and finally, the hoist is started through the confirmation buttons. The hoist repeats lifting and lowering according to the lift and lower data. It is also possible to manually control the lifting and lowering of the hoist through the lift and lower buttons, and the hoist is reset and stopped by pressing the confirmation button for the second time.

[0039] When it is necessary to repair the inside of the controller main body 101, it is necessary to disassemble the controller main body 101 and the backplane 204. By pressing the round rod 203a, the connecting rod 202 is driven to slide, so that the two magnets 205 are separated from each other, and the insertion rod 208 is driven to be pushed out of the rectangular block 207. After the rectangular block 207 loses the limit of the insertion rod 208, the backplane 204 can be separated from the controller main body 101;

[0040] When assembling the backplane 204 and the controller main body 101, by pressing the round rod 203a and then inserting the rectangular block 207 into the U-shaped block 201, at the same time, the sealing strip 206 will be inserted into the side wall of the controller main body 101, then the round rod 203a can be released, and the spring 203b will drive the round rod 203a to rebound, thereby driving the connecting rod 202 to reset. At this time, the insertion rod 208 passes through the U-shaped block 201 and is inserted into the rectangular block 207, and the assembly can be completed.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
