Description

Dustproof cover for axle

Technical Field

The application belongs to the technical field of the shield, and specifically relates to a bearing shield.

Background

In mechanical equipment, a dust cover is one of the most common parts and is used for preventing foreign matters such as dust from invading, but the dust cover in the prior art only has a dust-proof function, the foreign matters such as dust can be adhered to the surface of the dust cover and need to be cleaned regularly, otherwise, the invasion of the foreign matters such as debris and dust is difficult to guarantee, and the installation is troublesome.

SUMMERY OF THE UTILITY MODEL

In view of this, the technical problem that this application will be solved provides an axletree shield, through outer lid of interior cylinder cooperation, accomplishes to block dustproof, and inside first awl post is leading-in, and nanometer adsorbed layer adsorbs, and it is convenient to change, avoids the too single trouble of shield in the past.

In order to solve the technical problem, the utility model discloses an axle dust cap, which comprises an outer cap body and an inner cylinder body extending to the center of the outer cap body; the inner cylinder is provided with a central through hole and comprises a first conical column, a second annular groove and a third straight column which are positioned at the front end; the first cone column is provided with a cone part at the front end and a shaft part extending from the rear end, and the nano adsorption layer is attached to the cone part.

According to an embodiment of the present invention, the outer cover has chamfered portions at both ends and an external thread portion at the center.

According to an embodiment of the present invention, the outer cover body is formed with four fastening holes arranged around the other surface of the inner cylinder.

According to an embodiment of the present invention, the depth of the second annular groove is 2.7 mm.

According to an embodiment of the present invention, the outer cover and the inner post are made of polyethylene.

Compared with the prior art, the application can obtain the following technical effects:

through the outer lid of interior cylinder cooperation, accomplish to block dustproof, inside first awl post is leading-in, and the nanometer adsorbed layer adsorbs, and it is convenient to change, avoids the too single trouble of shield in the past.

Of course, it is not necessary for any one product to achieve all of the above-described technical effects simultaneously.

Reference numerals

The nano adsorption layer comprises an outer cover body 10, an inner cylinder body 20, a central through hole 21, a first conical column 30, a conical part 31, a shaft part 32, a second annular groove 40, a third straight column 50, a nano adsorption layer 60, a chamfer part 71, an outer thread part 72 and a fastening hole 80.

Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

Referring to fig. 1, fig. 1 is a schematic view of an axle dust cap according to an embodiment of the present application. As shown in the drawings, an axle dust cap includes an outer cap body 10 and an inner cylinder 20 extending in the center of the outer cap body 10; the inner cylinder 20 has a central through hole 21, and the inner cylinder 20 includes a first conical pillar 30, a second ring groove 40, and a third straight pillar 50 at the front end; the first tapered column 30 has a tapered portion 31 at the front end and a shaft portion 32 extending at the rear end, and the nano-adsorption layer 60 is attached to the tapered portion 31.

In one embodiment of the present invention, the outer cap 10 and the inner cylinder 20 form a dust cap body, wherein the inner cylinder 20 has a central through hole 21 for buffering air pressure. The inner cylinder 20 is divided into a first conical column 30 at the front end, a third straight column 50 at the rear end and a second annular groove 40 at the center, wherein the first conical column 30 is provided with a cone part 31 and a shaft part 32, the front end of the cone part 31 is led in, and a nano adsorption layer 60 is attached to the surface of the cone part 31, so that dust particles and internal water vapor can be effectively adsorbed, the protection is enhanced, and the shaft part 32 is tightly attached to the axle hole, so that the tightness is enhanced. The second ring groove 40 can be additionally sleeved with a sealing ring to enhance sealing, and the third straight column 50 is blocked by the sealing ring, so that an interval is formed and the disassembly is convenient. Preferably, the second ring groove 40 has a depth of 2.7mm, and is widely used.

The outer cover 10 has chamfered portions 71 at both ends and a central outer threaded portion 72 to facilitate the knob to be inserted into some axle screw holes, and the chamfered portions 71 are rounded.

Preferably, four fastening holes 80 are circumferentially arrayed on the other side of the outer cap 10 opposite to the inner cylinder 20, so that the fastening wrench can be conveniently detached.

In addition, the outer cover 10 and the inner cylinder 20 are made of high molecular polyethylene, and are stable in processing and forming and strong in durability.

The foregoing description shows and describes several preferred embodiments of the present application, but as aforementioned, it is to be understood that the application is not limited to the forms disclosed herein, but is not to be construed as excluding other embodiments and is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the application as described herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the application, which is to be protected by the claims appended hereto.
