[0029] Example 1:

[0030] See also Figure 1-5 The present invention describes the above technical solution in detail through the following embodiments:

[0031] A support for steel structure engineering, comprising:

[0032] The pull rod assembly 1 includes two pull rods 11. A connecting assembly is provided on the top of each pull rod 11. The connecting assembly is used to fix the pull rod 11. A first slide groove 12 is provided through the upper and lower parts of the pull rods 11. A cross bar assembly 2 is provided between the pull rods 11. The cross bar assembly 2 and the pull rod 11 are connected by a quick release assembly 3.

[0033] The connecting assembly includes a connecting sleeve 14, and a mounting bracket 15 is provided on the outside of the connecting sleeve 14. The connecting sleeve 14 and the mounting bracket 15 are fixedly installed on the outside of the top of the pull rod 11 by fixing bolts 18. A mounting hole 17 is provided through the top of the mounting bracket 15, and the mounting hole 17 is used to fix the mounting bracket 15.

[0034] The mounting frame 15 can be fixedly connected to the wall, roof or beam by means of expansion bolts, and the mounting holes 17 are used for the expansion bolts to pass through.

[0035] The mounting frame 15 is provided with four connecting holes 16 on the left and right sides. The four connecting holes 16 are diagonally symmetrical. The fixing bolts 18 pass through two diagonal connecting holes 16, so that the mounting frame 15 can be hoisted horizontally or from the top.

[0036] A plurality of positioning holes 13 are formed on the left and right sides of the back of the pull rod 11 . The distance between two adjacent positioning holes 13 is equal, and the axis of the positioning hole 13 passes through the center of the first sliding groove 12 .

[0037] The positioning hole 13 is a circular hole.

[0038] The crossbar assembly 2 includes a crossbar 21, the left and right end surfaces of the crossbar 21 abut against the back of the pull rod 11, and the crossbar 21 is provided with through holes 23 on the left and right sides. The top and bottom surfaces of the crossbar 21 are provided with pipe fixing brackets 25, which are used to fix the pipes;

[0039] The inner diameter of the through hole 23 is the same as the inner diameter of the positioning hole 13 .

[0040] A second sliding groove 22 is provided on the left and right sides of the surface of the crossbar 21 , and the pipe fixing frame 25 is fixedly connected to the second sliding groove 22 on the upper and lower sides through the first sliding block 24 .

[0041] The first slider 24 is engaged with the second slide groove 22 and can move along the second slide groove 22. The bottom of the pipe fixing frame 25 is fixedly connected to the first slider 24 by screws. By tightening the screws, the pipe fixing frame 25 and the first slider 24 can be used to clamp the second slide groove 22 to achieve the fixation of the pipe fixing frame 25.

[0042] The quick-release assembly 3 includes a snap ring 33, which is sleeved on the outside of the pull rod 11. A pin 37 is rotatably installed in the middle of the snap ring 33. The pin 37 passes through the first slide groove 12 and is inserted into the through hole 23. Both ends of the snap ring 33 are connected to the cross bar 21 through a reset assembly, and the reset assembly is used to drive the snap ring 33 to move horizontally.

[0043] The outer diameter of the latch 37 is the same as the inner diameter of the positioning hole 13 . The latch 37 passes through the positioning hole 13 and is inserted into the through hole 23 , which can limit the sliding of the cross bar 21 relative to the pull rod 11 , thereby fixing the cross bar 21 and the pull rod 11 .

[0044] The reset assembly includes a guide frame 32, which is fixedly connected to the second slide grooves 22 on the front and rear sides through a second fixed block 35. The guide frame 32 is slidably mounted with a slide rod 31, and the tail of the slide rod 31 is threadedly connected to an adjusting nut 34 through a retaining ring 33.

[0045] The second fixed block 35 is engaged with the second slide groove 22 and can move along the second slide groove 22. The bottom of the guide frame 32 is fixedly connected to the second fixed block 35 by screws. By tightening the screws, the guide frame 32 and the second fixed block 35 can be used to clamp the second slide groove 22 to achieve the fixation of the guide frame 32.

[0046] The adjusting nut 34 is welded to the snap ring 33 and pushes the slide bar 31, which can drive the snap ring 33 to move left and right through the adjusting nut 34. Since the tail of the slide bar 31 is threadedly connected to the adjusting nut 34, rotating the slide bar 31 can drive the slide bar 31 to move along its own axis, thereby changing the distance between the head of the slide bar 31 and the guide frame 32.

[0047] A return spring 36 is sleeved on the slide rod 31 , one end of the return spring 36 abuts against the side of the guide frame 32 away from the snap ring 33 , and the other end of the return spring 36 abuts against the head of the slide rod 31 .

[0048] The elastic force of the return spring 36 can drive the head of the slide rod 31 away from the guide frame 32 , thereby driving the snap ring 33 to move toward the pull rod 11 .

[0049] The tail of the latch 37 passes through the clamping ring 33 and is clamped with a knob 39 . A clamping block 38 is welded to the middle of the latch 37 , and the clamping block 38 is clamped with the first sliding groove 12 .

[0050] Rotating the knob 39 can drive the latch 37 to rotate, thereby driving the block 38 to rotate.

[0051] The thickness of the block 38 is the same as the opening width of the first chute 12 , the length of the block 38 is greater than the opening width of the first chute 12 , and the width of the block 38 is the same as the depth of the first chute 12 .

[0052] Therefore, the block 38 is engaged with the first sliding groove 12 in the horizontal state, thereby limiting the horizontal movement of the latch 37 .

[0053] After the clamping block 38 is rotated 90° from the horizontal state, it can release the clamping connection with the first slide groove 12. At this time, if the sliding rod 31 is used to drive the clamping ring 33 away from the pull rod 11, the clamping block 38 slides out of the first slide groove 12 and the pin 37 is separated from the through hole 23 and the positioning hole 13.

[0054] In this embodiment, when using the device, the operator first uses expansion bolts to fix the mounting bracket 15 on the wall or under the roof.

[0055] The connecting sleeve 14 is sleeved on the head of the pull rod 11 , and the mounting bracket 15 and the connecting sleeve 14 are fixedly connected by the fixing bolts 18 .

[0056] The knob 39 is used to rotate the clamping block 38 to a vertical state, pushing the slide bar 31 outward, and at the same time the return spring 36 is compressed, thereby pushing the clamping ring 33 to move outward.

[0057] Align the latch 37 and the block 38 with the bottom opening of the first slide groove 12 , insert them into the first slide groove 12 from below, and slide them upward. After sliding to a suitable position, release the thrust applied to the slide rod 31 .

[0058] At this time, under the elastic force of the return spring 36, the snap ring 33, the block 38 and the latch 37 move toward the cross bar 21 until the latch 37 passes through the positioning hole 13 and is inserted into the through hole 23, thereby fixing the cross bar 11 and the pull rod 21.

[0059] By rotating the latch 37 with the knob 39, the block 38 can be driven to rotate. After the block 38 rotates to a horizontal position, it engages with the first slide groove 12, thereby limiting the sliding of the latch 37 and locking the latch 37. This prevents the slide bar 31 from being accidentally touched and causing the cross bar 21 and the pull rod 11 to separate.

[0060] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
