DETAILED DESCRIPTION
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;
[0025] See also Figures 1 to 4 In the utility model, a detachable steel structure connection component includes an H-shaped steel 100, a connecting base plate 200, two positioning mechanisms 300 and a connecting mechanism 400.
[0026] Through holes 101 are provided at both ends of the inner side surface of the H-shaped steel 100; notches 201 are provided on the left and right sides of the top of the connecting base plate 200, and two grooves 202 distributed front and back are provided on the top of the connecting base plate 200; two positioning mechanisms 300 are respectively arranged in the two grooves 202 and are used to position the connecting base plate 200 and the H-shaped steel 100; the connecting mechanism 400 includes a bidirectional screw 401, two moving blocks 402, two connecting parts 403, two limiting columns 404 and two limiting holes 405, and the connecting mechanism 400 is used to connect the two H-shaped steels 100.
[0027] As a further description of the above technical solution: the bidirectional screw 401 is rotatably set on the connecting base plate 200, and the two ends of the bidirectional screw 401 extend into the two notches 201 respectively, and the outer wall of the bidirectional screw 401 is threadedly connected with two nuts 406 spaced along its length direction, and the two moving blocks 402 are respectively fixedly sleeved on the outside of the nuts 406, and the two moving blocks 402 are respectively slidably set on the inner sides of the two notches 201, and the two connecting pieces 403 are respectively fixedly connected to the opposite sides of the two moving blocks 402, and the two limiting columns 404 are both fixedly connected to the right side of the connecting piece 403 on the left side, and the two limiting holes 405 are opened on the left side of the connecting piece 403 on the right side, and the two limiting columns 404 can respectively pass through the through holes 101 on the inner sides of the two H-shaped steels 100 and be inserted into the two limiting holes 405;
[0028] Specifically, the bidirectional screw 401 rotates to make the nuts 406 at both ends move relative to each other, and the two nuts 406 respectively drive the two moving blocks 402 to move along the corresponding notches 201. When the two moving blocks 402 move, they respectively drive the two connecting members 403 to move relative to each other. When the two connecting members 403 move relative to each other, the limiting column 404 will pass through the through hole 101 and then be inserted into the limiting hole 405. The two connecting members 403 squeeze and clamp the H-shaped steel 100 to achieve the connection between the two H-shaped steels 100.
[0029] In this embodiment, preferably, the shapes of the two connecting pieces 403 are consistent with the inner shape of the H-shaped steel 100, and the connecting pieces 403 can be engaged with the inner side of the H-shaped steel 100;
[0030] Specifically, the connecting member 403 can be adjusted to the inner side of the H-beam 100. Since the connecting member 403 is engaged with the inner side of the H-beam 100 to limit the position of the H-beam 100, the H-beam 100 will not move left or right.
[0031] In this embodiment, preferably, the limiting column 404 forms a mortise and tenon structure with the through hole 101 and the limiting hole 405, the limiting column 404 is a tenon, and the through hole 101 and the limiting hole 405 are mortises;
[0032] Specifically, the limiting column 404 can first pass through the through hole 101 and then be inserted into the limiting hole 405 during the process of moving with the connecting member 403. Through the design of the mortise and tenon structure, the connection between the limiting column 404 and the H-shaped steel 100 and the limiting hole 405 is stable and firm.
[0033] In this embodiment, preferably, a U-shaped frame 407 is fixedly connected to the right side of the top of the bottom plate 200 and spans the right notch 201. A worm 408 is rotatably arranged inside the U-shaped frame 407. A worm wheel 409 meshing with the worm 408 is fixedly sleeved on the right end of the bidirectional screw 401.
[0034] Specifically, the rotation of the worm 408 drives the worm wheel 409 meshing with it to rotate, and the worm wheel 409 drives the bidirectional screw 401 to rotate. There is a self-locking function between the worm wheel 409 and the worm 408, so the worm wheel 409 can only drive the bidirectional screw 401 to rotate through the worm 408, thereby preventing the bidirectional screw 401 from self-rotating and causing looseness.
[0035] In this embodiment, preferably, the front end of the worm 408 penetrates and extends to the front side of the U-shaped frame 407, and the front end of the worm 408 is fixedly connected with a knob;
[0036] Specifically, the rotation of the worm 408 can be controlled by a knob, which is convenient to use.
[0037] In this embodiment, preferably, the two positioning mechanisms 300 both include a cross bar 301 fixedly connected in the groove 202, and hooks 302 are slidably provided at both ends of each cross bar 301, and a spring 303 sleeved on the outside of the cross bar 301 is fixedly connected between one side of the hook 302 and the inner wall of the groove 202, and the hook 302 is an "L"-shaped structure, and the hook 302 can be engaged with the H-shaped steel 100, and the width of the hook 302 is consistent with the width of the groove 202, and the hook 302 can move along the length direction of the groove 202;
[0038] Specifically, pull the hook 302 to slide along the cross bar 301 and squeeze the spring 303, so that the hook 302 moves to both sides of the connecting base plate 200 and makes the connecting base plate 200 fit onto the H-shaped steel 100. After releasing the hook 302, the hook 302 moves and fits onto the H-shaped steel 100 under the push of the elastic force of the spring 303, and positions the connecting base plate 200 on the H-shaped steel 100 for subsequent connection.
[0039] The working principle and use process of this utility model:
[0040] First, pull the hook 302 and squeeze the spring 303, fit the connecting base plate 200 to the H-shaped steel 100 and release the hook 302. Pushed by the elastic force of the spring 303, the hook 302 moves and engages on the H-shaped steel 100, and the connecting base plate 200 is positioned on the H-shaped steel 100 for subsequent connection.
[0041] Subsequently, after the connection base plate 200 is positioned between the H-beam 100 through the positioning mechanism 300, the worm 408 is controlled to rotate and drive the worm wheel 409 meshing with it to drive the bidirectional screw 401 to rotate. The bidirectional screw 401 rotates to make the nuts 406 at both ends move relatively. The two nuts 406 respectively drive the two moving blocks 402 to move along the corresponding notches 201. When the two moving blocks 402 move, they respectively drive the two connecting pieces 403 to move relatively. The connecting piece 403 moves to the inner side of the H-beam 100. Since the connecting piece 403 is engaged with the inner side of the H-beam 100 to limit the H-beam 100, the two connecting pieces 403 squeeze and clamp the H-beam 100 so that the H-beam 100 will not move left or right.
[0042] During the relative movement of the connecting member 403 , the limiting column 404 will pass through the through hole 101 and then be inserted into the limiting hole 405 , thereby realizing the connection between the two H-shaped steels 100 .
[0043] In summary, the two H-shaped steels 100 to be connected are connected through the connecting mechanism 400, and the operation process is convenient and quick. After the two H-shaped steels 100 are connected, they are not easy to loosen, the connection is stable and firm, and can be disassembled. Compared with the commonly used welding method, it saves time and effort, can be disassembled later, and has high overall practicality.

The electronic components and modules are all connected to an external power supply and a control switch for use. Their specific circuit connection methods and methods of use are commonly used public technologies and will not be elaborated on here.
[0045] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
