The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The embodiment of the invention provides an air pipe connecting structure which is used for connecting an air inlet pipe and an air conveying pipe.
As shown in fig. 1 to 4, the air pipe connection structure includes a sealing hose 10, an air pipe adapter 20, and a driving assembly 30. Wherein, the sealing hose 10 has resilience, and the diameter of the inner pipe of the sealing hose 10 is larger than the outer diameter of the air inlet pipe 40, so that the air inlet pipe 40 can be inserted into the inner pipe of the sealing hose 10. The air pipe adapter 20 is used for connecting an air pipe (not shown in the figure) and the sealing hose 10, specifically, the air pipe adapter 20 includes a first interface 21 butted with a pipe orifice of the sealing hose 10 and a second interface 22 connected with the air pipe, and the first interface 21 is communicated with the second interface 22. And the driving assembly 30 is used for driving the air pipe adaptor 20 and the sealing hose 10 to move along the pipe axis of the sealing hose 10, so as to press the sealing hose 10 and make the sealing hose 10 elastically deform until the inner wall surface elastically abuts against the outer wall surface of the air inlet pipe 40.
In the above, the elastic recovery means that when the sealing hose 10 is subjected to a certain external force, the sealing hose 10 is elastically deformed, and after the external force is removed, the sealing hose 10 is recovered to the original state; specifically, the seal hose 10 is a seal hose 10 made of a thermoplastic elastomer, which is a material having high elasticity, high strength, high resilience of rubber, and injection-moldable characteristics.
Based on the above structure, the connection process of the air inlet pipe 40 and the air pipe connection structure is, firstly, as shown in fig. 1, the air inlet pipe 40 is directly placed into the sealing hose 10, wherein, because the diameter of the pipeline in the sealing hose 10 is greater than the outer diameter of the air inlet pipe 40, the air inlet pipe 40 can be very conveniently and directly placed into the sealing hose 10, secondly, as shown in fig. 2, the air pipe adapter 20 and the sealing hose 10 are driven by the driving assembly 30 to move along the axial direction of the pipe of the sealing hose 10, so as to extrude the sealing hose 10 to enable the elastic deformation to reach the elastic collision between the inner wall surface of the sealing hose 10 and the outer wall surface of the air inlet pipe 40, and therefore, the connection between the air inlet pipe 40 and the air pipe connection structure is completed, and the whole process is simple and convenient. The sealing hose 10 deforms under the action of an external force applied by the driving assembly 30 and then elastically collides with the outer wall surface of the air inlet pipe 40, and when the external force applied by the driving assembly 30 is removed, the sealing hose 10 returns to the original state, and the phenomenon that the sealing hose 10 cannot elastically collide with the outer wall surface of the air inlet pipe 40 due to plastic deformation does not occur, so that based on the structure of the invention, after the sealing hose 10 is repeatedly inserted into the air inlet pipe 40, the sealing hose 10 still has good air tightness with the air inlet pipe 40, namely after the sealing hose 10 is repeatedly inserted into the air inlet pipe 40, the air tightness between the air pipe connecting structure and the air inlet pipe 40 is still good, and the air tightness between the air inlet pipe 40 and the air delivery pipe is ensured, so that the problem that the air tightness between the air inlet pipe 40 and the air delivery pipe cannot be ensured due to repeated use of the air delivery pipe is solved.
The movement of the air tube adapter 20 and the sealing hose 10 axially along the tube axis of the sealing hose 10 includes three conditions: (1) the sealing hose 10 is static, and the air pipe adapter 20 moves along the pipe of the sealing hose 10 axially to the sealing hose 10; (2) the air pipe adapter 20 is static, and the sealing hose 10 moves along the pipe of the sealing hose 10 to the air pipe adapter 20; (2) the air tube adapter 20 is moved axially along the tube of the sealing hose 10 toward the sealing hose 10, and at the same time, the sealing hose 10 is moved axially along the tube of the sealing hose 10 toward the air tube adapter 20. If the sealing hose 10 needs to move along the tube of the sealing hose 10 toward the air pipe adapter 20, the user also drives the sealing hose 10 and moves the air pipe adapter 20 together during the above-mentioned use process, so as to prevent the air inlet tube 40 from being separated from the sealing hose 10; of course, if the sealing hose 10 is stationary, it is not necessary to carry the sealing hose 10 along with the air tube adapter 20.
In addition, in practical use, the second interface 22 may be connected to the air pipe in advance, and after the air pipe 40 is connected to the air pipe connection structure, the air pump is started, and air is delivered to the air pipe 40 through the air pipe and the air pipe connection structure.
In the embodiment of the present invention, an end surface of the sealing hose 10 abutting against the air pipe adapter 20 is an abutting end surface 101, the air pipe adapter 20 has an abutting surface 201 abutting against the abutting end surface 101, the first port 21 is opened in the abutting surface 201, and the abutting surface 201 is parallel to the abutting end surface 101. Thus, the contact between the sealing hose 10 and the air pipe adapter 20 is surface contact, which is beneficial to increase the friction force between the sealing hose 10 and the air pipe adapter 20, and can avoid the radial movement of the abutting end surface 101 of the sealing hose 10 when the driving assembly 30 forces the sealing hose 10 to elastically deform.
Of course, further, as shown in fig. 1 to 4, the abutting end face 101 is perpendicular to the tube axis of the sealing hose 10. Based on this, when the driving assembly 30 forces the flexible sealing tube 10 to elastically deform, it can be known from mechanics knowledge that the direction of the acting force of the air pipe adapter 20 on the abutting end surface 101 of the flexible sealing tube 10 is parallel to the tube axis of the flexible sealing tube 10, and there is no component force in other directions, so that firstly, the radial movement of the abutting end surface 101 of the flexible sealing tube 10 when the driving assembly 30 forces the flexible sealing tube 10 to elastically deform can be further avoided, and secondly, the acting force of the air pipe adapter 20 on the abutting end surface 101 of the flexible sealing tube 10 can be fully used for extruding the flexible sealing tube 10, which is beneficial for the inner wall surface of the flexible sealing tube 10 to elastically abut against the outer wall surface of the air inlet tube 40 more tightly.
In the embodiment of the present invention, as shown in fig. 1 to 4, the abutting surface 201 extends inward to form an extending surface 202 disposed in an annular shape, the extending surface 202 of the air pipe connector is convexly provided with a protrusion 23 disposed annularly along the arrangement path of the extending surface 202, and an outer annular side surface 231 of the protrusion 23 elastically abuts against an inner wall surface of the sealing hose 10 when the driving assembly 30 forces the sealing hose 10 to deform elastically. Therefore, the contact surface between the sealing hose 10 and the air pipe adapter 20 is increased, and the air tightness between the sealing hose 10 and the air pipe adapter 20 is improved.
Further, as shown in fig. 3 and 4, the cross section of the protrusion 23 is tapered, and the taper direction is away from the tracheal adapter 20. Based on the structure, the inner ring side surface 232 of the protrusion 23 inclines outwards, and the protrusion 23 is positioned at the opening edge of the first connector 21, so that the channel through which the gas from the first connector 21 passes is gradually expanded, the gas is prevented from suddenly entering a larger pipeline from a smaller pipeline, the gas pressure is prevented from changing sharply, and the sealing hose 10 is pushed to expand outwards. Based on the structure, after the gas comes out from the first connector 21, the gas flows to the sealing hose 10 along the inner ring side surface of the protrusion 23, so that the protrusion 23 plays a role of buffering the gas pressure, and the gas tightness between the sealing hose 10 and the air pipe adapter 20 is prevented from being affected by the abrupt change of the gas pressure.
In the embodiment of the present invention, as shown in fig. 1 and 3, the sealing hose 10 has a tapered pipe section 11 abutting on the first interface 21, the inner pipe diameter of the tapered pipe section 11 is tapered along the pipe axis thereof and in the direction of the air pipe adapter 20, and the inner pipe diameter of the tapered pipe section 11 towards the pipe end of the sealing hose 10 is smaller than the outer diameter of the air inlet pipe 40. Based on the structure, in the process of placing the air inlet pipe 40 into the sealing hose 10, since the inner pipe diameter of the tapered pipe section 11 facing the pipe end of the sealing hose 10 is smaller than the outer diameter of the air inlet pipe 40, the air inlet pipe 40 is finally clamped and stopped at the position where the inner pipe diameter of the tapered pipe section 11 is equal to the outer diameter of the air inlet pipe 40, so that the position of the air inlet pipe 40 in the sealing hose 10 is favorably controlled by setting the position where the inner pipe diameter of the tapered pipe section 11 is equal to the outer diameter of the air inlet pipe 40.
In the embodiment of the present invention, as shown in fig. 1 and 3, the end surface of the sealing hose 10 facing away from the air pipe adapter 20 is a limiting end surface 102, and the driving assembly 30 includes a limiting fixing member 31 for limiting the movement of the limiting end surface 102 along the pipe axis of the sealing hose 10 in a direction facing away from the air pipe adapter 20, and a driving member 32 for driving the air pipe adapter 20 to press the sealing hose 10 toward the limiting fixing member 31. The driving member 32 includes a fixed shaft 321, an eccentric member 322 rotatably connected to the fixed shaft 321, and a driving handle 323 for driving the eccentric member 322 to rotate around the fixed shaft 321, and the air pipe adapter 20 has a driving end surface abutting against an eccentric periphery of the eccentric member 322. Based on this structure, only need through drive handle 323 drive eccentric 322 around fixed axostylus axostyle 321 rotate can, whole operation, it is simple convenient. In the present invention, the shape and structure of the eccentric member 322 and the air pipe adapter 20, and the contact position between the eccentric member 322 and the air pipe adapter 20 may be set according to the actual use requirement, which is not limited herein. Specifically, in the embodiment of the present invention, the eccentric member 322 is disposed in a segment shape, and the tracheal adapter 20 is disposed in an L-shape.
In the embodiment of the present invention, as shown in fig. 1 and 3, the fixing shaft 321 is fixed to the spacing fixing member 31. Thus, when the limit fixing piece 31 is produced, the position relationship between the driving member 32 and the limit fixing piece 31 is determined, and the position relationship between the driving member 32 and the limit fixing piece 31 does not need to be adjusted and arranged again in the follow-up process, which is beneficial to improving the follow-up assembly efficiency.
In the embodiment of the present invention, as shown in fig. 1 and fig. 3, the limiting fixing member 31 is provided with an accommodating cavity 311 which is used for placing and connecting the air delivery pipe and is arranged in a column shape, and a through hole 312 which is communicated with the accommodating cavity 311 and is located at the pipe orifice of the sealed hose 10 into which the air inlet pipe 40 is placed. Based on this structure, when extrusion sealing hose 10, the interior face of avoiding of holding chamber 311 is inconsistent with the outer wall surface of sealing hose 10 to the restriction sealing hose 10 expands outward, and this makes sealing hose 10 can only inwards contract, and makes the inner wall surface of sealing hose 10 and the outer wall surface of intake pipe 40 can better elasticity conflict, improves the gas tightness. In addition, when the air pipe connection structure does not need to be connected with the air inlet pipe 40, the limiting and fixing member 31 can be further provided with a rubber plug for blocking the perforation 312, so as to prevent dust from entering the sealing hose 10.
