Technical Field

[0001] The utility model relates to the technical field of seismic brackets, and particularly relates to an anti-rotation screw and a bracket connection structure. Background Art

[0002] A seismic bracket is various components or devices that limit the displacement of auxiliary mechanical and electrical engineering facilities, control the vibration of the facilities, and transfer the load to the bearing structure.

[0003] With the development of industrial level, engineering facilities in many places are often equipped with seismic brackets, so as to withstand the seismic action from any horizontal direction. In the prior art, the connection method of the seismic bracket is often to cooperate with the bracket connection structure through bolts and nuts, so as to rigidly connect the seismic bracket. Although this method has the basic connection function, since most bracket connection structures do not have a limit design for the screws, when the operator turns the nut, the screw will rotate with it. At this time, the operator needs to use other tools to fix the screw, and then turn the nut. The operation is too cumbersome, reducing the installation efficiency and the installation accuracy of the bracket connection. Therefore, it needs to be improved. Content of the Utility Model

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] As shown Figures 1 to 6 in the figure, the utility model provides an anti-rotation screw, including:

[0025] A bolt 1, which is composed of a screw head 2, an elliptical block 3, a round rod 4 and a threaded section 5. The right side of the screw head 2 is fixedly connected to the left side of the elliptical block 3. The right side of the elliptical block 3 is fixedly connected to the left side of the round rod 4. The right end of the round rod 4 is fixedly connected to the left end of the threaded section 5.

[0026] Since the outer shape of the elliptical block 3 is elliptical, when the elliptical block 3 is located in a slot hole that fits its outer shape, it will be restricted by the slot hole and thus cannot rotate, which in turn makes the entire bolt 1 unable to rotate.

[0027] Wherein, a nut 6 is movably sleeved on the outer surface of the threaded section 5. A threaded groove 7 is provided inside the nut 6, and the threaded groove 7 is matched with the thread on the threaded section 5.

[0028] Due to the design of the threaded groove 7, when the nut 6 rotates along the outer surface of the threaded section 5, at this time, the nut 6 will move to the left while rotating.

[0029] Wherein, the entire bolt 1 is made of medium carbon steel, and the outer surface of the elliptical block 3 is attached with a titanium alloy coating.

[0030] Since the entire bolt 1 is made of medium carbon steel, the entire bolt 1 will have good strength. Since the outer surface of the elliptical block 3 is attached with a titanium alloy coating, the elliptical block 3 will have excellent fatigue resistance and wear resistance.

[0031] Wherein, the entire nut 6 is made of carbon steel, and the outer shape of the nut 6 adopts a hexagonal structure.

[0032] Since the nut 6 is made of carbon steel, the entire nut 6 has good strength. Due to the outer shape structure design of the nut 6, it will enable the operator to conveniently screw the nut 6.

[0033] Wherein, a gasket is provided at the left end of the nut 6.

[0034] Due to the design of the gasket, the connection between the nut 6 and the bolt 1 will be more tight, thereby increasing the connection accuracy between the nut 6 and the bolt 1.

[0035] The bracket connection structure includes a connection block 8. A plurality of fixing grooves 10 matching the bolt 1 are provided on the connection block 8, and a set of positioning grooves 9 matching the bolt 1 are provided on the connection block 8.

[0036] Since the internal dimensions of the positioning groove 9 and the fixing groove 10 match the external dimensions of the elliptical block 3, when the elliptical block 3 is inside the positioning groove 9 or the fixing groove 10, the positioning groove 9 and the fixing groove 10 will restrict the rotation of the elliptical block 3, thereby preventing the entire bolt 1 from rotating along with it.

[0037] The working principle and usage process of the present utility model:

[0038] First, the operator fits the two connecting blocks 8 to the connection part of the seismic support. At this time, the opposite ends of the two connecting blocks 8 will come into contact. Immediately afterwards, the operator inserts the three bolts 1 as a whole into the inside of a set of positioning grooves 9 and two fixing grooves 10 respectively. At this time, the outer surfaces of the three bolts 1 as a whole will be movably sleeved inside the seismic support. At the same time, the outer surfaces of the three elliptical blocks 3 will respectively fit with the inside of the positioning grooves 9 and the fixing grooves 10. Since the inside of the positioning grooves 9 and the fixing grooves 10 and the outer surface of the elliptical block 3 are all designed in an elliptical shape, when the elliptical block 3 is inside the positioning grooves 9 and the fixing grooves 10, the positioning grooves 9 and the fixing grooves 10 will restrict the rotation of the elliptical block 3, thereby preventing the entire bolt 1 from rotating. Subsequently, the operator turns the nut 6 along the outer surface of the threaded section 5. Due to the design of the thread groove 7, at this time, the nut 6 will rotate along the outer surface of the threaded section 5 and move to the left at the same time. Due to the limitation of the positioning grooves 9 and the fixing grooves 10, the entire bolt 1 will not be able to rotate along with it, thus realizing the function of preventing the bolt 1 from rotating along with it.

[0039] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
