Description

Technical Field

[0001] The utility model relates to the technical field of rapid disassembly and assembly of jacquard machine workbench frames, and particularly relates to a special aluminum profile with a resonance anti-loosening structure. Background Art

[0002] Industrial aluminum profiles are alloy materials mainly composed of aluminum. Different cross-section-shaped aluminum materials are obtained by melting and extruding aluminum bars. After the surface of industrial aluminum profiles is oxidized, the appearance is very beautiful. When assembling into products, special aluminum profile fittings are used, which do not require welding, are more environmentally friendly, and are extremely convenient for installation, disassembly, carrying, and moving. They are widely used in automated mechanical equipment.

[0003] For example, a light aluminum profile for a whiteboard bracket disclosed in the authorized publication number CN219176721U has insertion slots provided on the aluminum profile main body, and hooks with a return hook angle are provided on both sides opposite to the opening ends of the insertion slots to prevent the fixing fittings from detaching from the insertion slots. Although this aluminum profile is sufficient to meet the requirements of rapid disassembly and assembly for the construction and disassembly of the workbench frame during use, when this profile is used for building the jacquard machine workbench frame, due to the reciprocating force generated in the horizontal direction during the operation of the jacquard machine, and the existing structure with hooks reduces the stress area between the fixing fittings and the profile, the screw connections of the fixing fittings become loose after long-term use of the jacquard machine workbench, resulting in the problem of unstable workbench.

It should be noted that the fittings required for building the jacquard machine workbench framework are selected from existing conventional fittings, that is, connecting angle pieces 3 and common bolts 4 or Figure 6An intermediate connecting plate used for assembling two second profile bodies. According to the required strength of the jacquard machine frame, multiple first profile bodies 1 can be selectively assembled and built, or the first profile body 1 and the second profile body 2 can be mixed and assembled and built, or multiple second profile bodies 2 can be assembled and built, etc., in various ways to improve the applicable range of the profile structure.

[0029] Refer to Figure 1 and 2 , the first profile body 1 is in the shape of a square strip, including a first load-bearing pipe 11 provided at the first center P of the first profile body 1 and extending along its length direction. First connecting grooves 12 are respectively formed on the four sides of the first profile body 1. At both ends of one side of the first connecting groove 12 facing the side of the first profile body 1, first limiting parts 13 are symmetrically provided. The first limiting parts 13 are inclined at a certain angle from the outer end of the corresponding side inward and toward the first center P. The inclination angle of the first limiting parts 13 is 2°. The first limiting parts 13 are inclined. When the frame is subjected to a transverse reciprocating force, the limiting parts can generate a reverse force on the bolt, thereby ensuring the locking force of the nut, so as to ensure that the nut will not loosen during long-term use and ensure the structural stability and rigidity of the frame. The first load-bearing pipe 11 is arranged at the center position of the first profile body 1 to ensure the rigidity of the profile body. In addition, threads are provided in the central circular hole of the first load-bearing pipe 11 to facilitate the connection of the end cover on the end face of the profile body to ensure the beauty and integrity of the frame.

[0030] Among them, the four first connecting grooves 12 are arranged in a cross shape and the center point of the cross coincides with the first center P. This layout makes the stress point located at the center of the first load-bearing pipe of the first profile body to ensure the stability of the force on the first profile body and the stability of the built frame. In addition, the bottom of the first connecting groove 12 is a V-shaped bottom composed of two inclined first reinforcing ribs 14, and the bottom of the V-shaped bottom is connected to the outer peripheral wall of the first load-bearing pipe 11. The setting of the reinforcing ribs further improves the strength of the profile body.

Second limiting parts 24 are symmetrically provided at both ends of one side of the second connection groove 23 facing the side edge of the second profile body 2. The second limiting parts 24 are inclined at a certain angle from the outer end of the corresponding side edge inward and toward the center point of the second load-bearing pipe 22. The inclination angle of the second limiting part 24 is 2°.

[0033] Among them, the three second connection grooves 23 of the docking unit are arranged in a T shape and the intersection of the T shape coincides with the center point of the corresponding second load-bearing pipe 22; that is, a total of six second connection grooves 23 are opened on the second profile body 2. From the perspective of the end face of the second profile body 2, the end face of the second profile body 2 is rectangular, and two second connection grooves 23 are respectively provided on the upper and lower long sides, and one second connection groove is respectively provided on the left and right short sides.

[0034] Furthermore, the bottom of the second connection groove 23 is a triangular bottom composed of two obliquely arranged second reinforcing ribs 25. An arc-shaped transition part 231 is provided on one side of the triangular bottom facing the second connection groove 23, and the other side is connected to the outer peripheral wall of the second load-bearing pipe 22.

[0035] In addition, a second load-bearing through groove 26 is opened on one side of the docking unit far from the wire threading groove 21. The second load-bearing through groove 26 is in a triangular structure, and second arc parts 261 are respectively provided at its connecting corners.

[0036] Refer to Figure 5 , the exploded structural schematic diagram of the assembly of two first profile bodies provided by the present utility model, that is, two first profile bodies 1 are placed perpendicular to each other to form a right angle. The first connection grooves 12 of the two first profile bodies 1 are aligned. By placing the bolt head in the first connection groove and making its connecting part pass through the installation hole of the corner piece and then using a nut to lock the corner piece. During the process of locking the nut, the bolt head is blocked by the limiting part to reinforce the locking force of the nut, thereby ensuring the stability and reliability of the built frame.

[0037] In addition, to ensure the lightness of the profile body, weight-reducing holes S penetrating the profile body along the length direction are opened at the four corners of the first profile body 1 and the second profile body 2. The weight-reducing holes S can be square through holes or circular through holes.

[0038] Furthermore, the bending parts on the profiles of the present utility model all adopt arc transitions, so that the profiles are stressed better to extend the service life of the profiles.

[0039] In summary, for the special aluminum profile of the resonance anti-loosening structure provided by the present utility model, by arranging the limiting part of the profile to be inclined at a certain angle in a specific direction, the locking force of the assembled fittings is ensured, thereby ensuring the structural stability and rigidity of the erected frame to prevent the frame from loosening; by arranging load-bearing through grooves on the profile, while ensuring the lightness of the profile, the strength of the profile is ensured, so as to save the use of profile raw materials and extend the service life of the profile.
