DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3The present embodiment provides a self-locking electric iron accessory connection device, comprising two symmetrically arranged groups of connecting frames 100, one end of the two groups of connecting frames 100 being connected together by a rotating connecting piece, and the other ends of the two groups of connecting frames 100 being connected together by a self-locking assembly, two groups of connecting columns 104 being fixedly connected to the opposite sides of the two groups of connecting frames 100, one end of the connecting columns 104 on the same side being fixedly connected to a mounting plate 103, and a mounting hole 105 for connecting the electric iron accessories being opened on the surface of the mounting plate 103;

[0024] The self-locking assembly includes a connecting plate 101 respectively installed at the same end of two groups of connecting frames 100, wherein the inner side of one group of the connecting plates 101 is connected to a plug-in block 201, and the surface of the other group of the connecting plates 101 is provided with a square hole 209 corresponding to the plug-in block 201, and the upper and lower sides of the square hole 209 are provided with a sliding groove 204, and the inner cavity of the sliding groove 204 is slidably connected to a clamping block 206, and the opposite ends of the two groups of the clamping blocks 206 are fixedly connected to a pull rod 207, and the two groups of the pull rod 207 respectively pass through the corresponding side sliding groove 204 and extend to the connecting plate 101. On the outside of the pull rod 207, a spring 205 is sleeved on the surface of the pull rod 207 in the inner cavity of the sliding groove 204. The two ends of the spring 205 respectively contact the surface of the clamping block 206 and the inner wall of one side of the sliding groove 204. The upper and lower surfaces of the plug-in block 201 are respectively provided with clamping grooves 202 corresponding to the clamping block 206. Through the setting of the self-locking component, the two sets of connecting frames 100 are connected quickly and have an automatic locking function to prevent accidental loosening, thereby ensuring the safety and stability of the connection, and the installation steps are very simple and quick, which is convenient for the staff to install it, thereby greatly improving the installation efficiency.

[0025] Furthermore, the rotating connecting member includes a connecting ring 301 fixedly installed at one end of one group of connecting frames 100, and a connecting groove 302 corresponding to the connecting ring 301 is opened at one end of the connecting frame 100 at the other end and at a position corresponding to the connecting ring 301. The connecting ring 301 is inserted into the inner cavity of the connecting groove 302, and a bolt 300 is slidably inserted at the top of the other group of connecting frames 100. One end of the bolt 300 passes through the connecting frame 100 and the connecting ring 301 in sequence and is threadedly connected with a nut 303. Through the setting of the rotating member, the cooperation between the connecting ring 301 and the connecting groove 302 and the connection method of the bolt 300 and the nut 303, a simple and effective rotating connection is provided, so that the connecting frame 100 can be flexibly rotated to the desired angle and fixed, thereby increasing the flexibility and adaptability of the device.

[0026] Furthermore, the surface of the nut 303 is plugged by a positioning pin 304. When the nut 303 is tightened, one end of the positioning pin 304 passes through the nut 303 and one end of the bolt 300 in sequence. The setting of the positioning pin 304 further prevents the nut 303 from loosening, enhances the reliability of the bolt 300 connection, and ensures the stability of the connection under vibration and other conditions.

[0027] Preferably, one end of the plug-in block 201 is threadedly connected to a forward and reverse screw 203, and the other end of the forward and reverse screw 203 is threadedly connected to the surface of the corresponding side connecting plate 101. Through the setting of the forward and reverse screw 203, the distance between the two groups of connecting plates 101 can be easily adjusted to adapt to the requirements of different sizes and installation conditions, thereby improving the versatility and applicability of the device.

[0028] It is worth noting that the opposite ends of the two groups of pull rods 207 are fixedly connected to the limiting plate 208, and one end of the limiting plate 208 is fixedly connected to the pull ring 200. Through the setting of the limiting plate 208 and the pull ring 200, the limiting plate 208 can prevent the pull rod 207 from excessive movement, ensuring the normal operation of the clamping block 206 in the sliding groove 204. The pull ring 200 facilitates the operation of the pull rod 207, making the unlocking operation more convenient.

[0029] Preferably, rubber sheets 102 are fixedly connected to opposite sides of the two groups of connecting frames 100. The provision of the rubber sheets 102 increases the friction between the connecting frames 100 and the poles, which helps to improve the stability of the connection.

[0030] Working principle;

[0031] When the bolt 300 is inserted into the connecting ring 301 at one end of the connecting frame 100, it passes through the connecting groove 302 at one end of the other connecting frame 100. The bolt 300 is passed through the connecting frame 100 and the connecting ring 301 in sequence and passes through the bottom of the connecting frame 100. The nut 303 is retracted and tightened. The locating pin 304 is used to pass through the nut 303 and the bolt 300 in sequence to connect the two connecting frames 100 together. At this time, the inner arc surface of one group of connecting frames 100 is close to the surface of the pole, and the other group of connecting frames 100 is flipped inward so that the plug-in block 201 installed at one end is plugged into the inner cavity of the square hole 209. When the plug-in block 201 is plugged into the inner cavity of the square hole 209, one end of the plug-in block 201 pushes the two groups of clamping blocks 206 into the inner cavity of the sliding groove 204 respectively. The two groups of clamping blocks 206 are respectively inserted into the inner cavity of the sliding groove 204 on the corresponding side, and When the connecting frame 100 is in the same position as the connecting slot 202 on the surface of the connecting frame 201, the connecting block 206 is inserted into the inner cavity of the connecting slot 202 under the push of the spring 205, fixing the connecting block 201, thereby fixing the two sets of connecting frames 100 to the surface of the pole.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
