Description

Technical Field

[0001] This application relates to the field of connecting structural parts, and particularly to a curved clip fastener applicable to support rings with different thicknesses. Background Art

[0002] Clip fasteners are important connecting structural parts in plate columns and packed columns. They are generally used for connections between tray plates and support rings, detachable liquid receiving trays and support rings, liquid distributors and support rings, etc. In a plate column, clip fasteners are generally used for connections between tray plates and support rings, and between detachable liquid receiving trays and support rings. Taking the tray plate and the support ring as an example, the tray plate near the tower wall is made into an arc shape and placed on the support ring welded to the tower wall, and is fixed with a clip fastener.

[0003] There is a commonly used fastener at present. Referring to Figure 1 , the fastener 01 is composed of an elliptical washer 02, a K-shaped clip 03, and a nut 04. The K-shaped clip 03 is composed of a clip plate 05 and a round head bolt 06. The head of the round head bolt 06 close to the clip plate 05 is welded to the bottom of the clip plate 05. A vertically upward flanging 07 is provided at one end of the clip plate 05, and the height of the flanging 07 is the same as the thickness of the support ring 08. A part of the tray plate 09 is placed above the support ring 08. One end of the clip plate 05 close to the support ring 08 is located below the support ring 08. The round head bolt 06 penetrates through the tray plate 09, and the elliptical washer 02 is sleeved on the round head bolt 06. After tightening the nut 04, the elliptical washer 02 abuts against the upper surface of the tray plate 09, the flanging 07 abuts against the lower surface of the tray plate 09, and one end of the clip plate 05 away from the flanging 07 abuts against the support ring 08 to clamp the tray plate 09.

[0004] In view of the above related technologies, when the thickness of the support ring is different, corresponding specifications of clip fasteners need to be used. If not carefully distinguished during the installation of the tray, installation errors often occur. The inventor believes that each specification of this kind of clip fastener can only be applicable to a support ring with one thickness, which increases the installation difficulty and affects the installation efficiency of the tray plate. Summary of the Invention

[0005] In order to improve the installation efficiency of the tray plate, this application provides a curved clip fastener applicable to support rings with different thicknesses.

[0006] The curved clip fastener applicable to support rings with different thicknesses provided by this application adopts the following technical solutions:

[0007] A curved surface clip fastener applicable to support rings of different thicknesses, comprising a curved surface clip plate arranged at the bottom of the support ring, a T-shaped bolt vertically arranged at one end of the curved surface clip plate, and a locking nut threadedly connected to the T-shaped bolt. One end of the curved surface clip plate abuts against the support ring, the end of the curved surface clip plate away from the support ring abuts against the tray plate, one end of the T-shaped bolt abuts against the curved surface clip plate, the other end of the T-shaped bolt sequentially penetrates through the curved surface clip plate and the tray plate from bottom to top, the locking nut is threadedly connected to the end of the T-shaped bolt away from the curved surface clip plate, and the locking nut abuts against the tray plate.

[0008] By adopting the above technical solution, after tightening the locking nut, the locking nut abuts against the upper surface of the tray plate, and the support ring and the end of the curved surface clip plate close to the tray plate abut against the lower surface of the tray plate, realizing the clamping of the tray plate. The elastic deformable curved surface clip plate abuts against the support ring, improving the applicable range of the clip fastener to the thickness of the support ring and reducing the installation difficulty caused by different specifications of the clip fastener, thereby improving the installation efficiency of the tray plate.

[0009] Optionally, the curved surface clip plate is arranged in a special-shaped curved surface formed by tangent arcs of different circles. The radian of the end of the curved surface clip plate close to the tray plate is greater than that of the end away from the tray plate, and a fitting surface that fits and abuts against the tray plate is provided at the end of the curved surface clip plate close to the tray plate.

[0010] By adopting the above technical solution, the special-shaped curved surface setting of the curved surface clip plate enables the clip fastener to have a larger space adjustment amount, can adapt to support rings of different thicknesses, and at the same time facilitates finding a suitable support point between the support ring and the tray plate. In addition, the processing and manufacturing of the special-shaped curved surface clip plate are simpler.

[0011] Optionally, a rectangular groove is opened along the length direction of the curved surface clip plate, a positioning groove plate is provided on the curved surface clip plate, the positioning groove plate is arranged in a cap shape, the positioning groove plate is slidably matched with the rectangular groove, and the positioning groove plate is fixedly connected to the T-shaped bolt.

[0012] By adopting the above technical solution, the positioning groove plate can slide along the rectangular groove, facilitating finding the support point between the support ring and the tray plate and further improving the installation efficiency of the tray plate.

[0013] Optionally, the positioning groove plate includes an upper plate arranged on the upper surface of the curved surface clip plate and two lower turning plates respectively arranged on both sides of the upper plate in the length direction. There is an included angle between the lower turning plate and the upper plate. The upper plate is arranged along the width direction of the curved surface clip plate. The T-shaped bolt penetrates through the upper plate. The length of the upper plate is greater than the width of the rectangular groove, and the length of the lower turning plate is less than the width of the rectangular groove. The lower turning plate is inserted and matched with the rectangular groove.

[0014] By adopting the above technical solution, when the positioning slot plate slides along the rectangular slot and finds a suitable supporting point between the support ring and the tower plate, the T-shaped bolt is rotated to make the two lower flaps tightly contact the side walls of the rectangular slot. At this time, continuing to rotate the T-shaped bolt will drive the curved surface clamping plate to rotate, so that the direction of the curved surface clamping plate can be adjusted by rotating the T-shaped bolt. During the adjustment process, the T-shaped bolt remains in a vertical upward state, so that the locking nut is not easy to loosen after being tightened.

[0015] Optionally, the upper plate is an arc-shaped plate, and the axis of the arc-shaped plate is located on the side of the upper plate facing away from the lower flap.

[0016] By adopting the above technical solution, the arc-shaped upper plate and the surface of the curved pallet with a special-shaped curved surface can be more closely fitted, thereby increasing the contact area between the two and improving the stability of the connection between the positioning slot plate and the curved pallet.

[0017] Optionally, the connection between the upper plate and the lower flap is provided with an arc chamfer.

[0018] By adopting the above technical solution, the stress concentration at the connection between the upper plate and the lower flap is reduced, the strength of the connection between the upper plate and the lower flap is enhanced, and the possibility of the lower flap detaching from the upper plate is reduced.

[0019] Optionally, an elastic washer is provided between the tower plate and the locking nut, one side of the elastic washer abuts against the tower plate, and the other side of the elastic washer abuts against the locking nut.

[0020] By adopting the above technical solution, the elastic washer is used to increase the contact area between the locking nut and the tower plate, so that the force on the surface of the tower plate is more uniform; at the same time, the elastic washer is used to increase the friction between itself and the locking nut, so that the locking nut is not easy to loosen.

[0021] Optionally, a limiting groove is provided at the end of the T-bolt close to the locking nut.

[0022] By adopting the above technical solution, when tightening the locking nut, a screwdriver is inserted into the limiting groove, and then the locking nut is tightened, thereby reducing the possibility of movement of the T-bolt when tightening the locking nut.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting an elastically deformable curved card plate, the clip fastener has a larger space adjustment amount, which increases the applicable range of the clip fastener for the thickness of the support ring, reduces the installation difficulty caused by different specifications of the clip fastener, and achieves the effect of improving the installation efficiency of the tower plate;

[0025] 2. After setting the positioning groove plate and determining the appropriate support points between the support ring and the tray plate, continue to rotate the T-shaped bolt, which can drive the curved surface clamping plate to rotate, achieving the effect of adjusting the direction of the curved surface clamping plate by rotating the T-shaped bolt. During the adjustment process, the T-shaped bolt remains in a vertically upward state, making it difficult for the tightened lock nut to loosen.

[0026] 3. By setting the arc-shaped upper plate, the upper plate fits more closely to the surface of the curved surface clamping plate, increasing the contact area between the two, achieving the effect of improving the connection stability between the positioning groove plate and the curved surface clamping plate.

Detailed Description of the Embodiment

[0033] The following will further elaborate on the present application in conjunction with the attached Figures 2 - 5 drawings.

[0034] The embodiment of the present application discloses a curved surface clip fastener applicable to support rings of different thicknesses. Refer to Figure 2, A curved surface clip fastener applicable to support rings of different thicknesses includes a curved surface clip 1, a T-shaped bolt 2, and a lock nut 3. One end of the curved surface clip 1 in the length direction is located at the bottom of the support ring 08, and one end of the curved surface clip 1 in the length direction abuts against the support ring 08. The other end of the curved surface clip 1 in the length direction abuts against the tray plate 09. The T-shaped bolt 2 is vertically arranged at the end of the curved surface clip 1 away from the support ring 08. The head of the T-shaped bolt 2 abuts against the bottom surface of the curved surface clip 1. The screw rod of the T-shaped bolt 2 sequentially penetrates through the curved surface clip 1 and the tray plate 09 from bottom to top. The lock nut 3 is threadedly connected to the screw rod of the T-shaped bolt 2, and the lock nut 3 abuts against the tray plate 09.

[0035] Refer to Figure 2 , An elastic washer 5 is also sleeved on the end of the T-shaped bolt 2 away from the curved surface clip 1. The elastic washer 5 is located between the tray plate 09 and the lock nut 3. The elastic washer 5 includes a horizontally arranged body part 51, a contact ring 52 arranged parallel to the body part 51, and a connecting part 53 connecting the body part 51 and the contact ring 52. The contact ring 52 is lower than the body part 51, and the connecting part 53 is a disc spring coaxially arranged with the body part 51. After tightening the lock nut 3, the lock nut 3 presses the body part 51, making the contact ring 52 abut against the tray plate 09 to press the tray plate 09. In addition, after tightening the lock nut 3, the disc spring bears the load and deforms, and stores a certain amount of potential energy. When the lock nut 3 becomes loose, it can release part of the potential energy to abut against the lock nut 3 itself.

[0036] Refer to Figure 2 , A limit groove 21 is opened on the T-shaped bolt 2. The limit groove 21 is arranged at the end of the T-shaped bolt 2 close to the lock nut 3. The limit groove 21 is a straight groove opened along the diameter direction of the screw rod of the T-shaped bolt 2. Before tightening the lock nut 3, insert a screwdriver into the limit groove 21 to limit the T-shaped bolt 2, reducing the possibility of the T-shaped bolt 2 moving during the process of tightening the lock nut 3.

[0037] Refer to Figure 3 , The curved surface clip 1 is arranged in a special-shaped curved surface formed by the tangency of different arcs, and the radian of the end of the curved surface clip 1 close to the tray plate 09 is greater than that of the end away from the tray plate 09. A fitting surface 11 is horizontally arranged at the end of the curved surface clip 1 close to the tray plate 09. The horizontally arranged fitting surface 11 abuts against the bottom of the tray plate 09, using the fitting surface 11 to increase the contact area between the curved surface clip 1 and the tray plate 09. The end of the curved surface clip 1 close to the tray plate 09 abuts against the support ring 08 through an arc surface. The curved surface clip 1 can adapt to support rings of different thicknesses through its own elastic deformation, making the curved surface clip fastener universal, making the installation of the tray plate 09 more convenient, and improving the installation efficiency of the tray plate 09.

[0038] Refer to Figure 4 and Figure 5A rectangular groove 12 is provided on one end of the curved surface card plate 1 near the T-bolt 2, and the length direction of the rectangular groove 12 is consistent with the length direction of the curved surface card plate 1. A positioning groove plate 4 is provided on the curved surface card plate 1, and the positioning groove plate 4 includes an upper plate 41 and two lower flaps 42. The upper plate 41 is provided horizontally, and the length direction of the upper plate 41 is provided perpendicularly to the length direction of the curved surface card plate 1. The two lower flaps 42 are respectively fixedly provided on both sides of the length direction of the upper plate 41, and the lower flaps 42 are provided vertically. The connection between the upper plate 41 and the lower flaps 42 is provided with arc chamfers 43.

[0039] Reference Figure 5 The upper plate 41 is located on the upper surface of the curved card plate 1, the length of the upper plate 41 is greater than the width of the rectangular groove 12, the length of the lower flap 42 is less than the width of the rectangular groove 12, the two ends of the upper plate 41 in the length direction are in contact with the upper surface of the curved card plate 1, the two lower flaps 42 are inserted into the rectangular groove 12, the T-shaped bolt 2 passes through the center position of the upper plate 41, and the T-shaped bolt 2 and the upper plate 41 are spot welded into one.

[0040] Reference Figure 3 and Figure 4 , so that the positioning slot plate 4 together with the T-bolt 2 moves along the length direction of the rectangular slot 12, making it easier to find a suitable support point between the support ring 08 and the tray plate 09, which helps to further improve the installation efficiency of the tray plate 09. At the same time, after determining the suitable support point, the direction of the curved surface clamping plate 1 can be easily adjusted by turning the T-bolt 2.

[0041] Reference Figure 3 and Figure 4 Since the curved pallet 1 is arranged in a special-shaped curved surface, the contact area between the horizontally arranged upper plate 41 and the curved pallet 1 is small, which will lead to poor stability of the connection between the positioning slot plate 4 and the curved pallet 1. An arc plate is used as the upper plate 41, and the axis of the arc plate is located on the side of the upper plate 41 away from the lower flap 42. The axis direction of the arc plate is consistent with the length direction of the upper plate 41, so that the upper plate 41 and the curved pallet 1 are in contact with each other.

[0042] The implementation principle of a curved clip fastener suitable for support rings of different thicknesses in an embodiment of the present application is as follows: when installing the tower plate 09, one end of the curved clip 1 in the length direction is in contact with the lower surface of the tower plate 09, and the other end of the curved clip 1 in the length direction is in contact with the lower surface of the support ring 08. At this time, the sliding positioning slot plate 4 is used to find a suitable support point between the support ring 08 and the tower plate 09, and then the locking nut 3 is tightened until the elastic washer 5 is in contact with the tower plate 09. At this time, the curved clip 1 is deformed according to the thickness of the support ring 08, and the end of the curved clip 1 close to the support ring 08 is in close contact with the lower surface of the support ring 08.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
