Description

Technical Field

[0001] The utility model relates to the technical field of cantilever brackets, in particular to a cantilever bracket which is easy to adjust. Background Art

[0002] When building highways and bridges, fixed piles are driven in first, and then the middle part is expanded on the fixed piles, a part of the frame is built, and a part of cement is poured. During the drying process of the cement after pouring, cantilever brackets are needed to support the newly poured road surface.

[0003] In the process of the cantilever support supporting the newly poured road surface, the continuous pouring of the new road surface requires the continuous movement of the support. The support is usually made of steel, and the usual way to move it is to move the track. However, the track is difficult to align completely, which may cause derailment during the movement, which may cause casualties.

[0004] Therefore, it is necessary to provide a cantilever bracket that is easy to adjust to solve the above technical problems. Utility Model Content

[0005] The utility model aims to provide a cantilever bracket which is easy to adjust and has the effect of allowing tracks to fit closely together and preventing the bracket body from easily derailing when the track is changed again.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a cantilever bracket that is easy to adjust, including a base, a symmetrical track is fixedly installed on the upper surface of the base, a bracket body is slidably connected to the track, a push rod is fixedly installed on the bracket body, and push handles are rotatably connected to both ends of the push rod. An arc-shaped groove is provided on the upper surface of the base, two sleeves are inlaid at one end of the arc-shaped groove, a rotating circle is rotatably connected between the two sleeves, a threaded rod is fixedly installed on the other end of the arc-shaped groove, one end of the threaded rod is provided with a thread and the other end is fixedly connected to the arc-shaped groove.

[0007] By adopting the above technical solution, when the position of the bracket body needs to be moved, another base with a track is taken, the two bases are aligned, and the threaded end of the threaded rod is inserted into the sleeve. The threaded rod is slidably connected with the sleeve until the threaded rod contacts the rotating circle. The rotating circle is rotated. The threaded rod will slowly extend into the sleeve and penetrate the sleeve as the rotating circle rotates until the two tracks collide with each other, and the rotating circle continues to rotate until the rotating circle cannot rotate. In this way, the tracks can fit tightly together, so that the bracket body will not easily derail when the track is changed again.

[0008] The utility model is further configured as follows: two cylindrical slide grooves are fixedly provided at both ends of the base, and when two bases are matched, positioning columns are slidably connected in the two cylindrical grooves.

[0009] By adopting the above technical solution, the presence of the positioning column effectively makes it necessary to change the position when another base is needed to make the tracks on the two bases fit closely together. First, the positioning column is extended into the cylindrical slide groove on the base with the bracket body above, and then the other base is moved so that the cylindrical slide grooves on both sides are aligned with the positioning column and the base is slowly pushed, so that the two positioning columns are slowly extended into the cylindrical slide grooves, and then the base is slowly pushed. In this way, the positioning column has been used for preliminary positioning before the threaded rod contacts the sleeve, which effectively allows the threaded rod to be accurately extended into the sleeve for positioning, thereby ensuring that the positioning is basically accurate before the track contacts.

[0010] The utility model is further configured as follows: a plurality of first slide grooves are provided at one end of the track, a plurality of second slide grooves are provided at the other end of the track, sliders are provided in the second slide grooves, and the sliders are slidably connected to the first slide grooves.

[0011] By adopting the above technical solution, when the slider is extended into the first slide groove, the first slide groove still contains air, and the air will be slowly discharged due to the extension of the slider, thus playing a certain buffering role.

[0012] The utility model is further configured as follows: a spring is arranged in the second sliding groove, one end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the track.

[0013] By adopting the above technical solution, when the slider extends into the first slide groove, the spring is compressed due to air resistance and friction, but is not completely compressed until the slider extends into the other end of the first slide groove. The spring will continue to be compressed and the spring generates elastic force on the slider, so that the slide rails are tightly clamped together.

[0014] The utility model is further configured as follows: a plurality of second columnar patterns are arranged on one side of the push handle.

[0015] By adopting the above technical solution, the setting of the second columnar pattern effectively increases the friction coefficient of the push handle surface, so that it will not slip when used.

[0016] The utility model is further configured as follows: a vertical pattern is provided on one side of the rotating circle.

[0017] By adopting the above technical solution, the vertical lines are effectively arranged to prevent the vehicle from slipping when the rotating circle is rotated.

[0018] The utility model is further configured as follows: a plurality of slots are provided in the track, a buckle is provided on the bracket body, and a clamping block penetrates the lower wall of the bracket body.

[0019] By adopting the above technical solution, after the position of the bracket body is determined, the buckle can be used to penetrate the lower wall of the bracket body and extend into the slot, so that the bracket can be prevented from sliding freely in the slot by the clamping column.

[0020] The utility model is further configured as follows: inclined surfaces are provided on both sides of the base.

[0021] By adopting the above technical solution, the setting of the inclined surface effectively prevents the base from colliding when the two rails collide, thereby effectively protecting the base and the rails.

[0022] In summary, the utility model has the following beneficial effects: the utility model can make the rails fit tightly together, so that the bracket body will not easily derail when changing the rails again. The setting of the positioning column effectively enables the threaded rod to accurately extend into the sleeve for positioning, thereby ensuring that the positioning is basically accurate before the rails contact. When the slider extends into the first slide groove, the first slide groove still contains air, and the air will be slowly discharged due to the extension of the slider, thus playing a certain buffering role. The setting of the spring strengthens the buffering effect and makes the slide rails tightly clamped together. The setting of the second columnar pattern effectively increases the friction coefficient on the surface of the push handle, so that it will not slip when used. The setting of the vertical pattern effectively makes it difficult to slip when rotating the rotating circle. The setting of the inclined surface effectively prevents the base from colliding when the two rails collide, effectively protecting the base and the rail. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In this embodiment, preferably, two cylindrical slide grooves 201 are fixedly provided at both ends of the base. When the two bases are matched, positioning columns 9 are slidably connected in the two cylindrical grooves. The presence of the positioning columns 9 effectively makes it necessary to change the position when another base is needed to make the tracks 4 on the two bases fit tightly together. First, the positioning columns 9 are inserted into the cylindrical slide grooves 201 on the base with the bracket body 1 above. Then, the other base is moved so that the cylindrical slide grooves 201 on both sides are aligned with the positioning columns 9 and the base is slowly pushed so that the two positioning columns 9 are slowly inserted into the cylindrical slide grooves 201. Then, the base is slowly pushed again. In this way, the threaded rod 5 has been preliminarily positioned by the positioning columns 9 before it contacts the sleeve 6, which effectively allows the threaded rod 5 to be accurately inserted into the sleeve 6 for positioning, thereby ensuring that the positioning is basically accurate before the track 4 contacts.

[0032] In this embodiment, preferably, a plurality of first slide grooves 401 are opened at one end of the track 4, and a plurality of second slide grooves 402 are opened at the other end of the track 4.

[0034] In this embodiment, preferably, a plurality of second columnar patterns 302 are provided on one side of the push handle 301; the provision of the second columnar patterns 302 effectively increases the friction coefficient on the surface of the push handle 301, so that the push handle 301 will not slip when used.

[0037] In this embodiment, preferably, both sides of the base 2 are provided with inclined surfaces 10 ; the setting of the inclined surfaces 10 effectively prevents the base from colliding when the two rails 4 collide, thereby effectively protecting the base and the rails 4 .

[0038] Working principle: When the position of the bracket body 1 needs to be moved, take another base 2 with a track 4, align the two bases 2, and need another base 2 to make the tracks 4 on the two bases 2 fit tightly together. First, extend the positioning column 9 into the cylindrical slide groove 201 on the base 2 with the bracket body 1 above, and then move the other base 2 to align the cylindrical slide grooves 201 on both sides with the positioning column 9, and slowly push the base 2 so that the two positioning columns 9 slowly extend into the cylindrical slide grooves 201, and then slowly push the base 2. In this way, the threaded rod 5 has been initially moved by the positioning column 9 before it contacts the sleeve 6. The step positioning effectively allows the threaded rod 5 to be accurately inserted into the sleeve 6 for positioning, ensuring that the positioning is basically accurate before the track 4 contacts, and the threaded end of the threaded rod 5 is inserted into the sleeve 6, and the threaded rod 5 is slidably connected with the sleeve 6 until the threaded rod 5 contacts the rotating circle 7, allowing the rotating circle 7 to rotate. The threaded rod 5 will slowly extend into the sleeve 6 as the rotating circle 7 rotates and penetrate the sleeve 6 until the two tracks 4 collide with each other, and continue to rotate the rotating circle 7 until the rotating circle 7 can no longer rotate, so that the tracks 4 can fit tightly together, and the bracket body 1 will not easily derail when the track 4 is changed again.
