Problems solved by technology

Although this method can easily carry the pump on the bicycle, it also has the following problems: 1. After the pump is fixed on the deck, the body of the pump will move along the The fixed direction slides down, making the fixing unreliable; 2. When the pump is not in use, external dust and water will enter the pump, causing damage to the piston seal inside the pump, affecting the service life of the pump, and speeding up pumping. Gas cylinder scrapping

Embodiment 1

[0017] Embodiment 1: As shown in the figure, a multi-functional dustproof cover for a portable pump includes an inner ring 1 and an outer ring 2, the inner ring 1 is used to fit on the outer tube of the pump, and the inner ring 1 One end is integrally connected with one end of the outer ring 2, and the other end of the outer ring 2 is suspended to form an elastic arm. The outer peripheral surface of the outer ring 2 is integrally provided with a sealing ring 21 for tight cooperation with the grip tube of the pump, and the outer ring 2 The end of the pump is integrally provided with a backstop ring 22, and the outer diameter of the backstop ring 22 is greater than the inner diameter of the end of the handle of the pump.

Embodiment 2

[0018] Embodiment 2: As shown in the figure, an air pump includes an outer tube 3, a grip tube 4 and a dust jacket 10, and an annular installation groove (not shown in the figure) is provided on the outer circumferential surface of the outer tube 3. The dustproof cover 10 includes an inner ring 1 and an outer ring 2. The inner ring 1 is set in the installation groove. The end of the inner ring 1 facing the handle 4 is integrally connected with the end of the outer ring 2 facing the handle 4. The other end of the outer ring 2 Suspended in the air to form an elastic arm, the outer peripheral surface of the outer ring 2 is integrally provided with a sealing ring 21. When the pump is not in use, the sealing ring 21 is closely matched with the inner wall of the grip tube 4, and the end of the outer ring 2 is integrally provided with a stopper. Retreat ring 22, the outer diameter of anti-retreat ring 22 is greater than the inner diameter of the handle pipe 4 end.

Abstract

The invention discloses a multifunctional dustproof cover used for a portable inflator. The multifunctional dustproof cover is characterized by comprising an inner ring and an outer ring; the inner ring is used for being arranged on an outer pipe of the inflator in a sleeving mode; one end of the inner ring and one end of the outer ring are integrally connected; the other end of the outer ring is suspended, and an elastic arm is formed; and the outer circumferential surface of the outer ring is provided with a sealing mechanism matched with a holding pipe of the inflator. The multifunctional dustproof cover used for the portable inflator has the advantages that the multifunctional dustproof cover is arranged in an installation groove of the outer pipe of the inflator in a sleeved mode, when the inflator is fixed to a clamping base and the clamping base is fixed to a bicycle frame, the end of the dustproof cover abuts against the upper end surface of the clamping base, the dustproof cover is arranged in the installation groove of the outer pipe in the sleeved mode, and the outer pipe of the inflator can be well prevented from sliding down, so that the inflator is firmly fixed to the clamping base; and meanwhile, the holding pipe is matched with the sealing mechanism on the outer ring of the dustproof cover, outside dust, water and other impurities can be prevented from entering the outer pipe, and the service life of the inflator is prolonged.

Description

technical field [0001] The invention relates to an air pump used for inflating tires in daily life, in particular to a multifunctional dustproof cover for a portable air pump and the air pump. Background technique [0002] The bicycle portable air pump that outdoor cycling enthusiasts use all is to fix the portable air pump on the deck at present, and then the deck is fixedly installed on the vehicle frame of the bicycle. Although this method can easily carry the pump on the bicycle, it also has the following problems: 1. After the pump is fixed on the deck, the body of the pump will move along the The fixed direction slides down, making the fixing unreliable; 2. When the pump is not in use, external dust and water will enter the pump, causing damage to the piston seal inside the pump, affecting the service life of the pump, and speeding up pumping. Gas cylinder scrapping. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
