Description

Technical Field

[0001] The present application relates to the technical field of aluminum rods, and specifically discloses an anti-oxidation aluminum rod that is resistant to wear at both ends. Background Art

[0002] Anti-oxidation aluminum rods are made of aluminum metal, which has been anodized or treated with other surface treatments to form a protective film on the surface to improve its corrosion resistance. These rods are available in a variety of alloy compositions and properties and are widely used in various fields. They are lightweight, high-strength, and corrosion-resistant. They are also easily processed into various shapes and sizes and can be formed through various processes, including casting, forging, extrusion, and rolling. Aluminum rods also have excellent weldability and can be joined to other metal materials using a variety of welding methods.

[0003] After the production and processing of the aluminum rod is completed, a film is usually used to protect the surface of the aluminum rod to prevent scratches on the surface of the aluminum rod and affect the appearance quality. However, since the aluminum rod is generally long and narrow, it is not convenient for the film to cover the through holes inside the aluminum rod. Therefore, the protection of the through holes inside the aluminum rod is usually carried out by covering the two ends of the aluminum rod with the film, which has a poor protection effect, making the end faces and the interior of the two ends of the aluminum rod prone to wear and scratching. Therefore, in view of this, the inventor provides an anti-oxidation aluminum rod with resistance to wear at both ends to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the problem that both end surfaces and the interior of both ends of the traditional anti-oxidation aluminum rod are easily worn and scratched, which affects the appearance quality of the aluminum rod product.

[0005] In order to achieve the above-mentioned object, the basic solution of the utility model provides an anti-oxidation aluminum rod with resistance to wear at both ends, comprising:

[0006] An aluminum rod body, wherein outer walls at both ends of the aluminum rod body are provided with outer matching grooves;

[0007] End covers, which are respectively arranged at both ends of the aluminum rod body and are provided with a plurality of clamping blocks that can be adapted to the external matching grooves;

[0008] A fixing sleeve is detachably connected to the end cover, and a clamping ring is provided on the inner wall of the fixing sleeve for clamping the clamping block to the outer matching groove.

[0009] The principles and effects of this basic solution are:

[0010] Compared with the existing technology, the present invention opens an external matching groove at the end of the aluminum rod body, and engages the clamping block with the external matching groove through a fixing sleeve, so that the end cover is used to protect the end of the aluminum rod body and the through hole inside the aluminum rod, thereby solving the problem that the end faces and the interior of the traditional anti-oxidation aluminum rod are prone to wear and scratching, which affects the appearance quality of the aluminum rod product.

[0011] Furthermore, the clamping block is hingedly connected to the outer wall of the end cap, and an extrusion strip is provided at one end of the clamping block near the inner wall of the fixing sleeve. This arrangement facilitates the clamping ring on the fixing sleeve to squeeze the clamping block, so that the clamping block and the outer matching groove engage with each other, thereby fixing the end cap and the aluminum rod body to each other.

[0012] Furthermore, the outer wall of the end cap is evenly provided with a plurality of connecting grooves that are adapted to the side walls of the clamping block, and the hinge is located on the side of the connecting grooves. This arrangement ensures that when the clamping block is engaged with the outer matching grooves, the contact surface between the clamping block and the end cap is more stable, making the connection between the clamping block and the end cap more stable.

[0013] Furthermore, one end of the clamping block extends out of the connecting slot and is provided with a clamping end adapted to the external matching slot. The end of the clamping end is provided with an inclined surface, and the end of the clamping end near the bottom of the external matching slot is provided with a curved surface adapted to the external matching slot. This arrangement facilitates the clamping block to be clamped into the external matching slot and improves the coordination between the clamping block and the external matching slot.

[0014] Furthermore, the ends of the aluminum rod body are provided with inner matching grooves, and the end caps are provided with protrusions adapted to the inner matching grooves. The provision of the inner matching grooves and protrusions can improve the protective effect of the end caps on the ends of the aluminum rod body and further improve the wear resistance of the ends of the aluminum rod body.

[0015] Furthermore, the end cap is provided with an external threaded surface on a side away from the aluminum rod body, the inner wall of the fixing sleeve is provided with an internal thread adapted to the external threaded surface, and the clamping ring is located at the end of the fixing sleeve. This arrangement facilitates the mutual cooperation between the end cap and the fixing sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0021] The reference numerals in the drawings of the specification include: aluminum rod body 1, end cover 2, fixing sleeve 3, outer matching groove 4, inner matching groove 5, protrusion 6, connecting groove 7, hinge ear 8, clamping block 9, extruded strip 10, and external thread 11.

[0022] An anti-oxidation aluminum rod with anti-wear at both ends, for example Figure 1 As shown, it includes an aluminum rod body 1, end covers 2 provided at both ends of the aluminum rod body 1, and a fixing sleeve 3 for fixing the end cover 2 and the aluminum rod body 1.

[0023] like Figure 2 As shown, the end surfaces of both ends of the aluminum rod body 1 are respectively provided with inner matching grooves 5, and the outer walls of both ends of the aluminum rod body 1 are respectively provided with outer matching grooves 4.

[0024] like Figure 3 As shown, the end cap 2 is internally provided with a protrusion 6 that fits into the inner matching groove 5. The protrusion 6 engages with the inner matching groove 5. Three connecting grooves 7 are evenly distributed around the outer wall of the end cap 2. The end of each connecting groove 7 is connected to a clamping block 9 via a hinge 8. A torsion spring is installed at the hinged connection between the clamping block 9 and the connecting groove 7. The end of the clamping block 9 extends beyond the end surface of the end cap 2 and is provided with a snap-fit ​​end that fits into the outer matching groove 4. The circumferential end of the snap-fit ​​end is covered with an elastic protective sleeve. The end of the snap-fit ​​end is provided with an inclined surface, and the end of the snap-fit ​​end near the bottom of the outer matching groove 4 is provided with an arcuate surface that fits into the outer matching groove 4. An extrusion strip 10 is provided on the surface of the clamping block 9, and the end of the extrusion strip 10 is also provided with an inclined surface.

[0025] The fixing sleeve 3 and the end cover 2 are connected and disassembled with each other through threaded cooperation. Specifically, the end of the end cover 2 is provided with an external thread 11, and the bottom of the inner wall of the fixing sleeve 3 is provided with an internal thread adapted to the external thread 11, and a retaining ring is provided at the opening of the inner wall of the fixing sleeve 3.

[0026] Through the threaded cooperation between the fixing sleeve 3 and the end cover 2, when the fixing sleeve 3 is rotated, the fixing sleeve 3 and the end cover 2 generate relative movement, so that the clamping ring in the fixing sleeve 3 moves along the inclined surface of the extruded strip 10, and applies pressure toward the center of the end cover 2 on the extruded strip 10 and the clamping block 9. With the cooperation between the clamping end of the clamping block 9 and the outer matching groove 4 of the aluminum rod body 1, the clamping block 9 and the outer matching groove 4 are fixed to each other, so that the end cover 2 and the aluminum rod body 1 can be fixed to each other. When the aluminum rod is used or installed, the fixing sleeve 3 is rotated in the opposite direction. The extrusion strip 10 and the clamping block 9 can be released, and at the same time, the elastic force of the torsion spring causes the clamping block 9 to separate from the outer matching groove 4 of the aluminum rod body 1. Compared with the prior art, the utility model opens the outer matching groove 4 at the end of the aluminum rod body 1, and engages the clamping block 9 with the outer matching groove 4 through the fixing sleeve 3, so that the end of the aluminum rod body 1 and the through-hole inside the aluminum rod are protected by the end cover 2, thereby solving the problem that the end faces and the interior of the traditional anti-oxidation aluminum rod are prone to wear and scratching, which affects the appearance quality of the aluminum rod product.

[0027] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
