Description

Technical Field

[0001] This utility model relates to a dustproof device for telescopic booms, belonging to the field of aerial work platforms. Background Technology

[0002] The existing dustproof system for telescopic booms uses a soft material scraper, which has gaps in its fit with the surface of the telescopic boom. Since the material and type cannot completely eliminate these gaps, and if there are protrusions on the surface of the telescopic boom, the scraper can be easily damaged, causing debris to be swept into the telescopic boom. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and to provide a telescopic arm dustproof device with a reasonable structural design.

[0004] The technical solution adopted by this utility model to solve the above problems is: the telescopic arm dustproof device has the following structural features: it includes a bracket, a brush and bolts. The upper part of the bracket is provided with a waist-shaped hole, the lower part of the bracket is provided with a U-shaped groove, the brush is located in the U-shaped groove, the bracket is installed at the arm head of the outer arm after the bolt passes through the waist-shaped hole, and the brush is in contact with the inner arm.

[0005] Furthermore, a bracket is installed on the upper, left, and right sides of the arm head of the outer arm.

[0006] Furthermore, a pressure strip is provided on the inner side of the U-shaped groove, which is used to press the brush tightly.

[0007] Furthermore, the brush is bonded or pressed into the U-shaped groove.

[0008] Compared with the prior art, the present invention has the following advantages: the dustproof device of the telescopic arm can fit tightly with the inner arm through the set brush, which can block the debris from falling into the telescopic arm, keep the inner arm of the telescopic arm clean, and improve the service life of the telescopic arm.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0015] Example

[0016] See Figures 1 to 4 As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0017] The telescopic arm dustproof device in this embodiment includes a bracket 3, a brush 4, and a bolt 7. The upper part of the bracket 3 is provided with a waist-shaped hole 6, and the lower part of the bracket 3 is provided with a U-shaped groove 5. The brush 4 is located in the U-shaped groove 5. The bracket 3 is installed at the arm head of the outer arm 1 after the bolt 7 passes through the waist-shaped hole 6. The brush 4 is in contact with the inner arm 2.

[0018] In this embodiment, a bracket 3 is installed on the upper, left and right sides of the arm head of the outer arm 1. A pressure strip 8 is provided on the inner side of the U-shaped groove 5. The pressure strip 8 is used to press the brush 4 tightly. The brush 4 is glued or pressed into the U-shaped groove 5.

[0019] Specifically, the brush 4 is glued or pressed into the U-shaped groove 5 and then installed on the arm head of the outer arm 1 by bolts 7. The mounting hole of the bracket 3 is a waist-shaped hole 6, which can adjust the gap between the bristles of the brush 4 and the contact surface. The bristles of the brush 4 are tightly attached to the inner arm 3. When not in operation, the brush 4 blocks debris from falling into the telescopic arm. When the inner arm 2 extends and retracts, it brushes away the debris outside, playing a dust removal role and keeping the inside of the telescopic arm clean.

[0020] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model are included within the protection scope of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined by the claims, all of which should fall within the protection scope of this utility model.
