Description

Technical Field

[0001] The utility model relates to the technical field of micro clamps, in particular to a connection structure of an integrated micro clamp. Background Art

[0002] Clamps are a highly versatile connector for automotive pipe connections, widely used in applications such as turbocharging, engine intake and exhaust ducts, and exhaust aftertreatment systems. However, currently, common micro-pipe connections for automotive aftertreatment systems, such as those for urea nozzles, are often made by stacking flanges and then tightening bolts. This connection design requires alignment of bolt holes during installation, resulting in low efficiency. Furthermore, multiple bolts must be removed during installation and maintenance, significantly impacting work time.

[0003] Therefore, there is still a need for an integrated micro-clamp connection structure to solve the above problems. Utility Model Content

[0007] The V-shaped ring has an opening, and connecting parts protruding from the outer side wall of the circular ring of the V-shaped ring are formed on both sides of the opening. The connecting parts have through holes for bolts to pass through. The through holes on the connecting parts on one side are strip-shaped, and the through holes on the connecting parts on the other side are circular.

[0008] In one embodiment, a plurality of avoidance grooves are formed on the inner side of the V-shaped ring, and the avoidance grooves are used to prevent the V-shaped ring from deforming.

[0009] In one embodiment, the avoidance groove is a notch formed on the inner side of the V-shaped ring for connecting the pipe, and the number of the avoidance grooves is three.

[0010] In one embodiment, the axial cross-section of the V-shaped ring is V-shaped or U-shaped, and the angle between two adjacent limiting portions is 30-50 degrees.

[0011] In one embodiment, the thickness of the V-ring is 0.8-1.5 mm.

[0012] In one embodiment, a limiting portion is formed on both sides of the V-shaped ring, and the limiting portion includes a side portion and a turning portion connected in sequence, and the angle between two adjacent side portions is 30-50 degrees.

[0013] Compared with the prior art, the beneficial effects of the present invention include at least:

[0014] During operation, the V-shaped ring is bent through the connecting parts on both sides to form an annular clamp, wherein the circular hole opened on the connecting part can be used for the bolt to pass through when screwing, so as to facilitate the quick positioning of the installation bolt during installation. The other strip-shaped through hole is used to connect the nut. The front end oval part of the nut passes through the connecting hole, which can prevent the nut from falling off from the connecting hole and is easy to align during installation.

[0020] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0021] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0022] XX, the present invention provides an integrated micro clamp connection structure, including: a V-ring 1 and a connection assembly 2; the connection assembly 2 includes a rivet nut 21, a bolt 22 and a retaining ring 23.

[0023] The V-ring 1 has an opening, and both sides of the opening are respectively formed with connecting parts 3 protruding from the outer side wall of the circular ring of the V-ring 1. The connecting part 3 has a through hole for the bolt 22 to pass through. The through hole on the connecting part 3 on one side is in the shape of a bar, and the through hole on the connecting part 3 on the other side is in the shape of a circle. The V-ring 1 is bent through the connecting parts 3 on both sides to form an annular clamp, wherein the circular hole opened on the connecting part 3 can be used for the bolt 22 to pass through when screwing, which is convenient for quickly locating the body of the installation bolt 22 during installation. When the nut is connected, the front elliptical part of the nut passes through the other bar-shaped through hole, which can prevent the nut from falling off from the connecting hole and is easy to align during installation. The retaining ring 23 is connected to the rod of the bolt 22 to play a sealing role.

[0024] In one embodiment, a plurality of avoidance grooves 4 are formed on the inner side of the V-ring 1 to prevent deformation of the V-ring 1. The avoidance grooves 4 can prevent material accumulation when the V-ring 1 is bent, thereby preventing stress concentration from causing breakage or bending.

[0025] In one embodiment, the avoidance groove 4 is a notch formed on the inner side of the V-shaped ring 1 for connecting the pipes, and there are three avoidance grooves 4. The three evenly distributed avoidance grooves 4 can evenly allocate and disperse stress to prevent excessive stress concentration.

[0026] Preferably, the axial cross-section of the V-ring 1 is V-shaped or U-shaped, and the angle between two adjacent limiting portions 5 is 30-50 degrees. Experimental tests have shown that the limiting portions 5 within this angle range can stably maintain the constrained pipeline force.

[0027] Preferably, the thickness of the V-ring 1 is 0.8-1.5 mm. Within this range, the V-ring 1 can effectively maintain good binding force.

[0028] Preferably, the V-shaped ring 1 has two limiting portions 5 formed on both sides. The limiting portions 5 include sequentially connected side portions 51 and folded portions 52, with the angle between two adjacent side portions 51 being 30-50 degrees. The side portions 51 can fully fit the inner pipe, and the folded portions 52 extend in the direction of the side portions 51, effectively holding the two connected pipe openings.

[0029] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limiting the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the present invention.
