Description
Technical field
The present invention relates to a kind of protective gear, be specifically related to a kind of telescopic rod protection device.
Background technique
The telescopic rod protection device of existing employing directly wraps up a telescopic protection cover outward at flexible rod; telescopic protection cover is directly fixed with fixed base and flexible rod; this method plays the effect of protection to a certain extent, but application is still very restricted.When flexible rod stroke is longer; due to the unbalance stress that the nonsymmetry of telescopic protection nested structure causes; and when being subject to the effect of applied environment fluid buoyancy or impact force; telescopic protection cover meeting gross distortion, the inwall that telescopic protection will be caused time serious to overlap and motion bar wear and tear mutually.When certain relative rotary motion made by flexible rod, telescopic protection cover two ends will produce twist relative, strengthen fatigue ruption, directly twist off time serious, therefore can reduce the working life of telescopic protection cover, thus have influence on the usability of flexible rod.
Summary of the invention
The object of the invention is: provide a kind of telescopic rod protection device, this device can be protected Long Distances, have the flexible rod of rotary motion, substantially increases that flexible rod is dust-proof, the protective value of waterproof and working life.
Technological scheme of the present invention is: a kind of telescopic rod protection device, and it comprises: flexible rod, fixed base, telescopic protection cover, pressing plate, slip solid ring, slip ring, limiting board A and limiting board B;
The latter end of flexible rod is provided with fixed base, and fixed base is stairstepping, and limiting board is arranged on the step of fixed base, and is undertaken axial spacing by the back-up ring A be arranged on this grade of ladder; Limiting board A and fixed base contacting point are provided with groove A;
First section of flexible rod is provided with limited step and spacing groove, and limiting board B is arranged on first section of flexible rod, and is undertaken axial spacing by limited step and the back-up ring B be arranged in spacing groove; First section of contacting point of limiting board B and flexible rod is provided with groove B;
The stage casing of flexible rod is provided with the solid ring that slides, and the solid ring that slides contacts with the stage casing of flexible rod by being arranged on the slip ring bottom it; The quantity of the solid ring of slip is more than two or two;
Between limiting board A and the solid ring of slip between solid ring, adjacent of sliding, sliding is provided with telescopic protection cover between ring and limiting board B admittedly, and the two ends of telescopic protection cover are connected with limiting board A, slide ring and limiting board B admittedly respectively by pressing plate.
The invention has the beneficial effects as follows: (1) the present invention adopts one or more telescopic protection cover to be connected in series; and be connected with slip ring by pressing plate, the solid ring that slides in joint; the sealing of joint can be improved on the one hand; the solid ring that slides on the other hand plays the effect of support, substantially reduces telescopic protection and overlaps the possibility contacted with flexible rod.
(2) the limiting board A that connected by pressing plate of telescopic protection cover two ends and limiting board B can be rotated by relative telescopic bar; and be provided with dust ring or seal ring; play dust and water protection effect; can also prevent telescopic protection cover from turning round bad, therefore the present invention can play a very good protection to the flexible rod that stroke is large, have rotary motion.

In figure: 1-flexible rod, 2-fixed base, 3-telescopic protection cover, 4-pressing plate, 5-slip solid ring, 7-slip ring, 9-limiting board A, 10-back-up ring A, 11-groove A, 12-limiting board B, 13-back-up ring B, 14-groove B.
Embodiment
See accompanying drawing 1, a kind of telescopic rod protection device, it comprises: flexible rod 1, fixed base 2, telescopic protection cover 3, pressing plate 4, slip solid ring 5, slip ring 7, limiting board A9 and limiting board B12;
See accompanying drawing 2, the latter end of flexible rod 1 is provided with fixed base 2, and fixed base 2 is stairstepping, and limiting board A9 is arranged on the step of fixed base 2, and is undertaken axial spacing by the back-up ring A10 be arranged on this grade of ladder; Limiting board A9 and fixed base 2 contacting point are provided with groove A11;
See accompanying drawing 3, first section of flexible rod 1 is provided with limited step and spacing groove, and limiting board B12 is arranged on first section of flexible rod 1, and is undertaken axial spacing by limited step and the back-up ring B13 be arranged in spacing groove; First section of contacting point of limiting board B12 and flexible rod 1 is provided with groove B14;
See accompanying drawing 4, the stage casing of flexible rod 1 is provided with the solid ring 5 that slides, and the solid ring 5 that slides is contacted with the stage casing of flexible rod 1 by the slip ring 7 be arranged on bottom it; The quantity of the solid ring 5 of slip is more than two or two;
Between limiting board A9 and the solid ring 5 of slip between solid ring 5, adjacent of sliding, sliding admittedly is provided with telescopic protection and overlap 3 between ring 5 and limiting board B12, and the two ends that telescopic protection overlaps 3 are connected with limiting board A9, slide ring 5 and limiting board B12 admittedly respectively by pressing plate 4.Pressing plate 4 plays and compresses the effect that telescopic protection overlaps 3 connecting end surfaces guarantee good airproof performances; the solid ring 5 that slides plays a part to connect support telescopic protection cover 3, prevents from contacting with flexible rod 1 when telescopic protection cover 3 is subject to the flex under action such as fluid buoyancy or impact force and rubs.The present invention is being provided with slide solid ring 5 and slip ring 7 between the outer multiple telescopic protection cover 3 of flexible rod; no matter flexible rod 1 is in is stretched or all plays effect that is dust-proof or waterproof under rotary motion; particularly for the flexible rod 1 that stroke is larger, slide ring 5 and slip ring 7 admittedly can also play and prevent fluid impact etc. from causing telescopic protection to overlap the effect of being out of shape and mutually wearing and tearing with flexible rod.
