Detailed Description
The present application is described in further detail below with reference to figures 1-7.
The embodiment of the application discloses flexible hydro-cylinder with dust keeper.
Referring to fig. 1, a telescopic cylinder with a dust-proof device includes a telescopic rod 1 and a cylinder barrel 2. The cylinder barrel 2 is sleeved with a brush looped pile 21, and the part of the brush looped pile 21 with the brush hairs 211 is contacted with the telescopic rod 1. Because dust particulate matter is many in the operational environment that telescopic cylinder is in, when stretching out in telescopic link 1 follow cylinder 2, the particulate matter in the air is the very easy adhesion on telescopic link 1 surface, consequently when telescopic link 1 gets back to in the cylinder 2, can bring the particulate matter together into, pollutes the hydro-cylinder. And the setting of brush looped pile 21 makes brush hair 211 and 1 surface of telescopic link produce the friction when telescopic link 1 withdraws the hydro-cylinder for the particulate matter of telescopic link 1 surface adhesion is swept away by brush hair 211, can not cause the hydro-cylinder to pollute.
Referring to fig. 2 and 3, two symmetrical telescopic holes 22 are formed in the cylinder 2, each telescopic block 23 is arranged in each telescopic hole 22, one end, close to the axis of the cylinder 2, of each telescopic block 23 is connected with a compression spring 231, one end, away from the telescopic blocks 23, of each compression spring 231 is fixed in each telescopic hole 22, and the brush pile loop 21 is provided with a through hole 212 matched with the telescopic block 23. The structure enables the brush hair ring 21 and the cylinder barrel 2 to be detachable, and is more convenient and labor-saving when the brush hair ring 21 is damaged or needs to be replaced.
Meanwhile, the part of the telescopic block 23 extending out of the cylinder barrel 2 is provided with a guide surface facing the telescopic rod 1 along the axial direction of the cylinder barrel 2, and when the guide surface 232 extends out of the telescopic hole 22, a certain distance exists between the guide surface 232 and the telescopic hole 22. Through the structure, when the bristle ring 21 moves to the telescopic block 23 along the axial direction from the telescopic rod 1 to the cylinder barrel 2, the bristle ring can directly slide to the position where the peripheral through holes 212 are clamped with the telescopic block 23 along the guide surface only by pressing the telescopic block 23 into the guide surface to be contacted with the telescopic hole 22. The arrangement of the guide surface enables the brush pile loop 21 to be more conveniently installed, the telescopic block 23 does not need to be completely pressed into the telescopic hole 22, and the telescopic block 23 does not need to be manually pressed all the time in a compressed state. The guide surface 232 and the telescopic hole 22 have a certain distance, so that the telescopic rod 1 cannot drive the brush terry 21 to break away from the clamping structure along the guide surface when retracting into the cylinder barrel 2, and the fixing structure of the brush terry 21 and the cylinder barrel 2 is more stable.
Referring to fig. 4 and 5, a first protruding block 233 is disposed on the circumferential surface of the telescopic block 23 in the cylinder 2, a first sliding groove 221 and a second sliding groove 222 which are matched with the first protruding block 233 are disposed in the cylinder 2, the first sliding groove 221 is connected with the second sliding groove 222, the first sliding groove 221 extends toward the axis, and the second sliding groove 222 extends along the circumferential surface of the telescopic hole 22. When the brush loop 21 needs to be replaced or disassembled, the retractable block 23 is pressed into the retractable hole 22, so that the first projection 233 slides along the first sliding groove 221 to the joint of the first sliding groove 221 and the second sliding groove 222, and then the retractable block 23 is rotated, so that the first projection 233 slides into the second sliding groove 222. By the mode, the telescopic block 23 can be fixed in the telescopic hole 22 and does not extend out, and the telescopic block 23 does not need to be supported by hands or tools all the time, so that the operation is more convenient. The cylinder barrel 2 around the telescopic block 23 is provided with the abdicating position 24 on the circumferential surface, so that the rotation of the telescopic block 23 is easier to realize and more labor-saving.
Referring to fig. 6 and 7, the brush loop 21 is formed by splicing two semicircular parts, one of the connecting surfaces of the two semicircular parts is provided with a second L-shaped projection 213, and the other connecting surface is provided with a hook groove 214 matched with the second L-shaped projection. When brush looped pile 21 need be dismantled, need not dismantle whole flexible hydro-cylinder get off, directly break away from the joint structure with two semicircle brush looped piles 21, just can dismantle brush looped pile 21 from 1 both sides of telescopic link for brush looped pile 21's dismantlement is more convenient.
The brush looped pile 21 is provided with the baffle 215 on one side of the brush bristles 211 close to the cylinder barrel, and the baffle 215 prevents the brush bristles 211 from being bent towards the cylinder barrel 2 along with the telescopic rod 1 when the telescopic rod 1 retracts into the cylinder barrel 2, so that the brush bristles 211 cannot enter the oil cylinder to pollute the oil cylinder.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
