Abstract
A joint anti-skid device of a rubber air duct relates to the field of coal mining equipment and comprises an air duct A and an air duct B, wherein the two ends of the air duct A and the air duct B are both wrapped by circular rings A, and the circular ring A at one end of the air duct A is clamped in the air duct B. The joint anti-skid device is characterized in that the inner walls of the air duct A and the air duct B are both provided with circular rings B, the circular rings B and the circular rings A are equal in diameter, the distance between the circular ring A at one end of the air duct A and the corresponding circular ring B is equal to the distance between the circular ring A at one end of the air duct B and the corresponding circular ring B, the inner wall of an air duct between each circular ring A and each circular ring B is provided with circular rings C, the outer duct walls of the air duct B are provided with circular rings D which are arranged between the circular rings A and the circular rings C, and the diameters of the circular rings D are smaller than those of the circular rings A and are equal to those of the circular rings C. Three sealing parts are integrally formed, so that the sealing performance is good, and the effect is obvious.
Description
Technical field:
The utility model relates to coal mine equipment field, is specifically related to rubber air duct joint shoe.
Background technology:
At present, mine roadway draft type mainly adopts booster forced ventilation, using air duct as fresh wind for wind path strength, along with scientific and technological development local ventilation acc power is increasing, air feed distance is more and more longer, and this has just increased the workload of air duct continuous operation, so air duct need to be connected with air duct, traditional directly ties up iron wire in junction, not only tie up difficulty, remove also very inconvenience, and for the air duct of quality of rubber materials, leaking out, appear in iron wire destructible air duct.
Utility model content:
Technical problem to be solved in the utility model is to overcome the defect of prior art, and a kind of Quick connecting, the good rubber air duct joint of sealing shoe realized is provided.
Technical problem to be solved in the utility model realizes by the following technical solutions.
Rubber air duct joint shoe, comprise air duct A and air duct B, annulus A is wrapped up respectively at air duct A and air duct B two ends, the annulus A of air duct A one end is stuck in air duct B, it is characterized in that: described air duct A and the inwall of air duct B are all provided with annulus B, annulus B and annulus A equal diameters, described air duct A one end annulus A and the distance of annulus B, equate with annulus B distance with the annulus A of air duct B one end, air duct inwall in the middle of described annulus A and annulus B is provided with annulus C, described air duct B outer tube wall is provided with annulus D, annulus D is located between annulus A and annulus C, described annulus D diameter is less than annulus A, annulus D diameter equals annulus C.
Described annulus B is rubber ring, and the easy cover of rubber ring is easily got on the one hand, and the plasticity of rubber ring is strong on the other hand, and applicability is large.
Described rubber ring cross section is triangle, is difficult for rolling, and strengthens skidproof effect.
The utility model is simple in structure, reasonable in design, and air duct A is sticked in air duct B, and annulus A engages mutually with annulus B, annulus C engages with annulus C, pulls air duct A, makes annulus A and annulus B, it is tightr that annulus C engages with annulus C, and annulus D is stuck between two annulus C, makes junction V-shaped, annulus C is at cylinder inwall, and annulus D is at drum outer wall, and barrel clamping is tightr, the whole three seals place that forms, good airproof performance, without screw, thing is tied up, simple and practical, successful.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Wherein: 1: air duct A; 2: air duct B; 3: annulus A; 4: annulus B; 5: annulus C; 6: annulus D.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Rubber air duct joint shoe as shown in Figure 1, comprise air duct A1 and air duct B2, annulus A3 is wrapped up respectively at air duct A1 and air duct B2 two ends, the annulus A3 of air duct A3 one end is stuck in air duct B2, the inwall of air duct A1 and air duct B2 is all provided with annulus B4, annulus B4 and annulus A3 equal diameters, wherein air duct A1 one end annulus A3 and the distance of annulus B4, equate with annulus B4 distance with the annulus A3 of air duct B2 one end, wherein the air duct inwall in the middle of annulus A3 and annulus B4 is provided with annulus C5, wherein air duct B2 outer tube wall is provided with annulus D6, annulus D6 is located between annulus A3 and annulus C5, wherein annulus D6 diameter is less than annulus A3, annulus D6 diameter equals annulus C5, annulus D6 is rubber ring, rubber ring cross section is triangle.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
