DETAILED DESCRIPTION

[0023] like Figures 1 to 6 As shown, the present invention is a joint structure for connecting a support and a purlin, comprising: a main plug 1 and a main slot 2 arranged along the same axis, the main plug 1 is telescopically connected to a secondary plug 101, and the telescopic direction is perpendicular to the axial direction, the main slot 2 is provided with a main socket for the main plug 1 to be inserted along the axial direction and a secondary socket 203 for the secondary plug 101 to be inserted along the direction perpendicular to the axial direction, and the secondary socket 203 is connected to the main socket; and also includes a driving member 3 installed on the main plug 1 and used to drive the secondary plug 101 to telescope.

[0024] like Figure 2-Figure 3As shown, the main plug 1 includes: a second box body 102 detachably connected to one side of the support 4; a groove, the groove is opened along the axial direction on the side of the second box body 102 away from the purlin 6, the auxiliary plug 101 is telescopically arranged on the outer periphery of the second box body 102, and an installation space is formed in the second box body 102. The outer wall of the second box body 102 is opened with a telescopic opening for the auxiliary plug 101 to be telescopic, and the telescopic opening is connected to the installation space. The driving member 3 is installed in the installation space and connected to the auxiliary plug 101; the main slot 2 includes a first box body 201 fixed to the surface of the purlin 6, the main socket 204 is opened along the axial direction on one side of the first box body 201 away from the purlin 6, and the auxiliary socket 203 is opened on the inner wall of the main socket 204 along the direction perpendicular to the axis.

[0025] like Figure 1 to Figure 3 As shown, an opening is provided on the outer wall of the second box body 102, a bolt 5 is passed through the opening, a screw hole matching the opening is provided on the supporting surface, and the bolt 5 is screwed into the screw hole.

[0026] like Figure 4 The auxiliary plug 101 includes a head 104 and a spring 304 fixed at one end to the head, and the other end of the spring 304 is inserted into the installation space and fixed to the main plug 1. The driving member 3 includes: a spring 304 extending along the telescopic direction of the auxiliary plug 101, and the two ends of the spring 304 are respectively connected to the auxiliary plug 101 and the main plug 1, and also includes a slide groove 303 arranged on the outside of the spring 304 parallel to the extension direction of the spring 304, an operating rod 308 fixed to one end of the slide groove 303 in a direction perpendicular to the slide groove 303, a sliding rod 302 arranged parallel to the operating rod 308 and slidably arranged in the slide groove 303, and two connecting rods hinged between the operating rod 308 and the sliding rod 302, wherein the sliding 302 rod passes through the slide groove 303 and is inserted into the spring 304 in a direction perpendicular to the spring 304. By rotating the operating rod 308 to drive the two connecting rods to swing and then drive the sliding rod 302 to slide, the extension amount of the spring 304 is adjusted to achieve the telescopic adjustment of the auxiliary plug 101.

[0027] Preferably, if Figure 4 As shown, in this embodiment, the slide groove 303 and the spring 304 of the driving member 3 are both located inside the main plug 1, and a knob 301 is also fixed to the top of the operating rod 308. By setting the knob 301, the knob 301 extends out of the main plug 1 so that the operating rod 308 can be selected by rotating the knob 301.

[0028] Preferably, in this embodiment, the two connecting rods include a first strip plate 307 and a second strip plate 305, the first strip plate 307 and the second strip plate 305 are hinged by a hinge rod 309, and the operating rod 308 is fixedly penetrated through one end of the first strip plate 307; the hinge rod 309 is hinged to the other end of the first strip plate 307; one end of the second strip plate 305 is hinged to the hinge rod 309, and the other end is hinged to the sliding rod 302; the sum of the lengths of the second strip plate 305 and the first strip plate 307 is greater than the length of the slide groove 303.

[0029] When in use, the operating rod 308 is rotated, and the operating rod 308 drives the first strip plate 307 to rotate with the operating rod 308 as the axis, and at the same time drives the second strip plate 305 to swing, and drives the sliding rod 302 to slide along the sliding groove. The sliding of the sliding rod 302 drives the spring 304 to expand and contract, so as to control the expansion and contraction of the auxiliary plug 1-1.

[0030] like Figure 1 to Figure 3 As shown, a side of the secondary plug 101 close to the main slot 2 is provided with an arc surface. By setting the arc surface, the connector 1 shrinks when it contacts the main slot 2 when entering the slot member 2, and is automatically pushed in when the secondary socket 203 is released, so as to facilitate the insertion of the connector 1.

[0031] like Figure 5 As shown, a wall-embedded member 202 is fixed on the contact surface of the main slot 2 with the surrounding purlin 6, and the wall-embedded member 202 is anchored in the surrounding purlin 6. By providing the wall-embedded member 202, the connection between the main slot 2 and the surrounding purlin 6 is further strengthened.

[0032] When the present invention is in use, one end of the surrounding purlin 6 is first connected to the main plug 1, and then the driving member 3 is used to retract the auxiliary plug 101, and the main plug 1 is inserted into the main socket 204. After the main plug 1 is inserted, the driving member 3 is operated again to extend the head 104 of the auxiliary plug 101 and insert it into the auxiliary socket 203, thereby completing the connection between the support 4 and the surrounding purlin 6. When the support 6 needs to be removed, the auxiliary plug 101 only needs to be retracted again by the driving member 3 to remove the main plug 1 from the main socket 204.

[0033] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
