Detailed ways

The present invention will be further illustrated below in conjunction with specific examples, which are implemented on the premise of the technical solutions of the present invention. It should be understood that these examples are only used to illustrate the present invention and not to limit the scope of the present invention.

Example 1

As shown in Figure 1, Figure 2 and Figure 3, an adjustable pre-embedded channel includes a channel body 1, the channel body 1 is a C-shaped channel, and its cross section is "C" shape, the channel body 1 One end is provided with a first support part 2 and a second support part 3 for supporting the T-bolt 9, between the two support parts is an opening, the T-bolt 9 is vertically placed into the channel body 1 from the opening and then rotated The first support part 2 and the second support part 3 can be supported by the first support part 2 and the second support part 3 at 90 degrees. The first support part 2 is movably connected with the first adjustment block 4. The first adjustment block 4 includes a first extension block 41 and a first connecting rod. 42 and the first nut 43, the first connecting rod 42 is welded or integrally formed with the first extension block 41, the first connecting rod 42 is threaded, the first nut 43 is threadedly connected with the first connecting rod 42, the first supporting part 2 There is a first through hole 21 on the top, the first connecting rod 42 penetrates through the first through hole 21, the first adjustment block 4 is located above the first support part 2, and the first nut 43 is located below the first support part 2. The first adjustment block 4 is fixedly connected with the first support part 2, and the second support part 3 is provided with a second adjustment block 5 symmetrical with the first adjustment block 4, and the second adjustment block 5 includes a second extension block 51, a second adjustment block 5, and a second adjustment block 5. The connection structure of the connecting rod 52 and the second nut 53 is the same as that of the first adjusting block 4 , the second connecting rod 52 is welded or integrally formed with the second extension block 51 , and the second support portion 3 is provided with a second through hole 31 , The second connecting rod 52 penetrates through the second through hole 31 , and the second nut 53 is threadedly connected to the second connecting rod 52 .

As shown in FIG. 4 , when the medium bolt 91 is used, since the bolt head of the medium bolt 91 is placed in the channel body 1 and then rotated 90 degrees, the width d1 of the bolt head is smaller than the width D of the opening of the channel body 1, Therefore, the medium bolt 91 cannot be connected with the channel body 1. At this time, the first adjustment block 4 is rotated to make the first extension block 41 protrude toward the second adjustment block 5, and then the first nut 43 is tightened to make the first adjustment block 4 Fixed, so that the width of the opening is reduced, and the medium bolt 91 can be used normally.

As shown in FIG. 5 , when the small bolts 92 are used, since the head width d2 of the small bolts 92 is smaller, the second extension block 51 of the second adjusting block 5 needs to be rotated to make it move toward the first adjusting block. 4 places protrude, so that the width of the opening is smaller, so that the small bolt 92 can be used with the channel body 1 normally.

As shown in FIG. 6 , the channel body 1 is a straight channel (or an arc channel according to the usage requirements). The back of the channel body 1 is connected with two anchor rods 6 (the number of anchor rods is reasonably set according to the needs), A plurality of pairs of the first adjusting block 4 and the second adjusting block 5 are evenly arranged on the channel body 1 .

As shown in FIG. 7 , the top wall of the inner cavity of the channel body 1 is provided with an annular spring groove 7 (the number of annular spring grooves can be set in multiples to match springs of different sizes). There is a spring 8 on the head, and the annular spring groove 7 corresponds to the size of the coil body of the spring 8. When the T-bolt 9 is put into the groove body 1, the top end of the spring 8 falls into the annular spring groove 7, and the spring 8 rises. To the limit function, the spring 8 uses its elasticity to press the T-bolt 9 against the first adjustment block 4 and the second adjustment block 5. When the channel body 1 is installed vertically or inclined at a certain angle to the horizontal plane, it can prevent T-bolt 9 slips off.
