Description
Technical field
The present invention relates to a kind of protective gear, be specifically related to a kind of flexible rod protective gear.
Background technique
The flexible rod protective gear of existing employing is outside flexible rod, directly to wrap up a telescopic protection cover; telescopic protection cover and fixed base and flexible rod are directly fixing; this method plays the effect of protection to a certain extent, but application is still very restricted.When flexible rod stroke is longer; the unbalance stress causing due to the nonsymmetry of telescopic protection nested structure; and the used time of doing that is subject to applied environment fluid buoyancy or impact force; telescopic protection cover meeting gross distortion, will cause inwall and the motion bar of telescopic protection cover mutually to wear and tear when serious.When flexible rod is made certain relative rotary motion, telescopic protection cover two ends will produce relative distortion, strengthen fatigue ruption, when serious, directly twist off, and therefore can reduce the working life of telescopic protection cover, thereby have influence on the usability of flexible rod.
Summary of the invention
The object of the invention is: a kind of flexible rod protective gear is provided, and this device can be protected large stroke, have the flexible rod rotatablely moving, greatly improved that flexible rod is dustproof, protective value and the working life of waterproof.
Technological scheme of the present invention is: a kind of flexible rod protective gear, and it comprises: flexible rod, fixed base, telescopic protection cover, pressing plate, slip be ring, slip ring, limiting board A and limiting board B admittedly;
The latter end of flexible rod is provided with fixed base, and fixed base is stairstepping, and limiting board is arranged on the one-level ladder of fixed base, and is undertaken axial spacing by being arranged on back-up ring A 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 by limited step and be arranged on back-up ring B in spacing groove and carry out axial spacing; 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 of its bottom; The solid quantity of encircling of sliding is more than two or two;
At limiting board A and slide between solid ring, adjacent slip admittedly encircle between, between slide solid ring and limiting board B, be provided with telescopic protection cover, the two ends of telescopic protection cover respectively by pressing plate with limiting board A, slide and admittedly encircle and limiting board B is connected.
The invention has the beneficial effects as follows: (1) the present invention adopts one or more telescopic protection covers to be connected in series; and be connected with slip ring by pressing plate, the solid ring that slides in joint; can improve the sealing of joint on the one hand; the solid ring that slides on the other hand plays the effect of support, has greatly reduced the possibility that telescopic protection cover contacts with flexible rod.
(2) the limiting board A that telescopic protection cover two ends connect by pressing plate can rotate by relative flexible rod with limiting board B; and be provided with dust ring or seal ring; play dust and water protection effect; can also prevent telescopic protection cover turn round bad, so the present invention can be large to stroke, there is the flexible rod rotatablely moving and play a very good protection.

Fig. 4 is the partial enlarged drawing of Fig. 1;
In figure: 1-flexible rod, 2-fixed base, 3-telescopic protection cover, 4-pressing plate, the solid ring of 5-slip, 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
Referring to accompanying drawing 1, a kind of flexible rod protective gear, it comprises: flexible rod 1, fixed base 2, telescopic protection cover 3, pressing plate 4, slide admittedly encircle 5, slip ring 7, limiting board A9 and limiting board B12;
Referring to 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 9 is arranged on the one-level ladder of fixed base 2, and is undertaken axial spacing by being arranged on back-up ring A10 on this grade of ladder; Limiting board A9 and fixed base 2 contacting points are provided with groove A11;
Referring to 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 by limited step and be arranged on back-up ring B13 in spacing groove and carry out axial spacing; First section of contacting point of limiting board B12 and flexible rod 1 is provided with groove B14;
Referring to accompanying drawing 4, the stage casing of flexible rod 1 is provided with slip and admittedly encircles 5, and slip admittedly encircles 5 and contacts with the stage casing of flexible rod 1 by being arranged on the slip ring 7 of its bottom; It is more than two or two sliding and admittedly encircling 5 quantity;
At limiting board A9 and slide admittedly encircle between 5, adjacent slip admittedly encircle 5 between, slide admittedly encircle 5 with limiting board B12 between be provided with telescopic protection cover 3, the two ends of telescopic protection cover 3 respectively by pressing plate 4 and limiting board A9, slip admittedly encircle 5 and limiting board B12 be connected.Pressing plate 4 plays the effect that telescopic protection overlaps 3 connecting end surfaces assurance good airproof performances that compresses; slide and admittedly to encircle 5 and play a part to connect and support telescopic protection cover 3, prevent from contacting and rubbing with flexible rod 1 when telescopic protection cover 3 is subject to bending under the effects such as fluid buoyancy or impact force.The present invention is provided with slip in 3, the cover of a plurality of telescopic protections outside flexible rod and admittedly encircles 5 and slip ring 7; no matter flexible rod 1 is in the flexible or lower effect of all playing dustproof or waterproof that rotatablely moves; particularly for the larger flexible rod 1 of stroke, slide admittedly encircle 5 and slip ring 7 can also play the effect that prevents that fluid impact etc. from causing the distortion of telescopic protection cover and flexible rod mutually to wear and tear.
