Abstract
The utility model relates to a negative pressure pipe wear resistant device, the cover has an elastic metal dysmorphism snap ring 2 on the body 4 of each air current guide way department of negative pressure pipe, and the snap ring is through curved coupler body 1 in upper and lower both ends, 6 cards on body 4, and snap ring 2 corresponds position department at negative pressure pipe air current guide way and opens and have with negative pressure pipe air current guide way shape complex guide way. The grid ring is directly contacted with the surface of the metal snap ring, so that the surface of the pipe body is not abraded, the negative pressure pipe does not need to be replaced, and the metal snap ring is clamped on the negative pressure pipe, so that the replacement is very convenient.
Description
Affiliated technical field the utility model relates to the negative pressure pipe that negative pressure is provided for twisting on the compact spinning machine.
The negative pressure pipe of negative pressure is provided for twisting on the present compact spinning machine of background technology, offer the air-flow guiding skewed slot of 6 parallel distributions on its body, outside at skewed slot puts grid ring, during yarn process skewed slot place, under the negative-pressure adsorption effect in the negative pressure pipe, the filoplume on the yarn is attracted on the network circle and with the spin of yarn and twines twisting.Because yarn constantly drives grid ring and rotates on body, making body surface abrasion, time grow needs to change the negative pressure pipe, and the negative pressure pipe is changed pretty troublesome.
Summary of the invention is to be solved in the utility model be above-mentioned negative pressure pipe body surface abrasion and change inconvenience problem.
The utility model is to solve like this: be with an elastic metallic abnormity snap ring on the body at each air-flow gathering sill place of negative pressure pipe, snap ring is stuck on the negative pressure pipe body by the coupler body of two ends arc up and down, and snap ring has the gathering sill with negative pressure pipe air-flow gathering sill form fit in negative pressure pipe air-flow gathering sill corresponding position.
Because grid ring directly contacts with the metal clasp surface, makes the body surface not frayed, do not need to change the negative pressure pipe, and metal clasp is to be stuck on the negative pressure pipe, thereby changes easily.
Description of drawings Fig. 1 is the utility model structural representation.
Fig. 2 is along A-A line cutaway view among Fig. 1.
The specific embodiment is by shown in Figure 1, offer the air-flow gathering sill [7] of 6 parallel distributions on the negative pressure pipe body [4], be with an elastic metallic abnormity snap ring [2] on the body at each air-flow gathering sill place, as shown in Figure 2, snap ring [2] is stuck on the negative pressure pipe body [4] by the coupler body [1,6] of two ends arc up and down, and snap ring has the gathering sill with negative pressure pipe air-flow gathering sill form fit in negative pressure pipe air-flow gathering sill [7] corresponding position.Coupler body [5] both sides of snap ring lower end arc have outward flanging to form the rafter [5] of projection, play tension, and snap ring is close on the negative pressure pipe body, can prevent effectively that snap ring is at axial float.Between snap ring [2] and negative pressure pipe body [4] contact-making surface, be provided with elastic rubber gasket [3], drive the strain of rubber gasket by the elasticity of snap ring, thereby can guarantee air-flow gathering sill on the snap ring and the sealing between the body air-flow gathering sill, can prevent effectively that negative pressure from reducing.
Claims (3)
1, a kind of negative pressure pipe wear-resistant device, it is characterized in that on the body [4] that each air-flow gathering sill [7] of negative pressure pipe is located, being with an elastic metallic abnormity snap ring [2], snap ring is stuck on the body [4] by the coupler body [1,6] of two ends arc up and down, and snap ring [2] has the gathering sill with negative pressure pipe air-flow gathering sill form fit in negative pressure pipe air-flow gathering sill [7] corresponding position.
2, negative pressure pipe wear-resistant device according to claim 1 is characterized in that the rafter [5] of the oriented outer lug in coupler body [6] both sides of snap ring lower end arc.
