DETAILED DESCRIPTION

[0025] The utility model will be further explained in combination with the description of the drawings and the specific embodiment.

[0026] For example, Figures 1-9As shown, the utility model is a kind of air pipe adapter box mounting structure, including mattress and the air pipe adapter box 1 fixed thereon, air pipe adapter box 1 has the pipe seat 4 with inner and outer connectors, inner and outer connectors are connected respectively the gas pipe of air bag and the lead-out gas pipe 15 of outer gas supply, air pipe adapter box 1 is fixed in the end region of mattress on the side of foot, and air pipe adapter box 1 part is inserted into the side of mattress and is fixed.This embodiment air pipe adapter box 1 includes the box body 2 fixed in the side of mattress and its inner fixed seat 3 and the pipe seat 4 connected in fixed seat, both sides in box body 2 are the open mouth of communicating box cavity, fixed seat 3 is loaded into box cavity from outside open mouth and is fixed, the inner connector of pipe seat 4 passes through fixed seat 3 and extends into box cavity, the outer connector of pipe seat 4 connects lead-out gas pipe 15 and extends box body 2 through the inner outlet 5 opened on fixed seat 3 and the outer outlet 6 opened on box body 2 and extends box body 2.

[0027] Because air pipe adapter box is arranged in the end region of mattress on the side of foot, and is away from the active area of mattress in use, the influence of the loosening and displacement of air pipe adapter box caused by the activity of mattress is reduced, and air pipe adapter box is also inserted from the side of mattress to the inside for fixation, so that the positioning reliability of air pipe adapter box is further improved, and the loosening and displacement of air pipe adapter box caused by the activity of mattress in use are avoided, and the normal inflation and deflation of air bag are not affected.

[0028] Further, the mattress includes a surrounding edge layer 7 around the periphery and a lining layer wrapped therein, the lining layer is provided with an air bag and is connected to the air pipe adapter box 1 through a gas pipe, the box body 2 is inserted and fixed in the surrounding edge layer 7 on the side of mattress, the surrounding edge layer 7 is provided with a transversely penetrating mounting hole and the box body 2 is inserted and matched, a fastening structure is arranged between the side wall of box body 2 and the inner wall of mounting hole, the fastening structure is a plurality of barbs 8 on the outer surface of side wall of box body 2, which are perpendicular to the insertion direction of box body 2, the barbs 8 can increase the friction force of the contact surface of mounting hole when box body 2 tends to exit from the mounting hole, and the outer end of box body 2 is further provided with a stop edge which can abut against the outer end surface of mounting hole.

[0029] The air pipe adapter box is inserted and fixed in the mounting hole of surrounding edge layer through the box body, after the box body is inserted in place, the stop edge abuts against the outer end surface of mounting hole for positioning, and the fastening structure between the side wall and the inner wall of mounting hole prevents the air pipe adapter box from loosening and moving outward, the plurality of barbs in the fastening structure are tightly inserted with the mounting hole, when the box body tries to exit from the mounting hole, the barbs can increase the friction force of the contact surface of mounting hole, so that the box body is prevented from being pulled out outward.

[0030] As shown in the figure, the top surface of the barb convex ridge is a wedge surface 8-1 which is inclined downward to the side of the insertion direction of the box 2. When the box is inserted into the mounting channel, the inner wall of the mounting channel is deformed to gradually press the wedge surface from the thinnest section to the thickest section into the mounting channel. Conversely, when the box tends to exit the mounting channel, the thickest section of the wedge surface is pressed against the inner wall of the mounting channel, increasing the friction of the contact surface, making it difficult to pull out the box, and further fastening the connection between the box and the mounting channel. In order to improve the fastening of the box and the mounting channel, the outer surface of the side wall of the box 2 is provided with a plurality of barb convex ridge groups, and each barb convex ridge group is provided with 2-4 rows of parallel barb convex ridges 8.

[0031] Further, the surrounding edge layer 7 is further wrapped with a mattress cover 9, and the mattress cover 9 is provided with an opening corresponding to the open side of the box 2 for the fixing seat 3 to be inserted into the box. The outer end of the fixing seat 3 is provided with a second flange 3-1 along the circumference to protrude outside the mattress cover 9. The blocking edge of the box 2 is a first flange 2-1 which extends along the circumference of the open end surface of the outer side of the box 2. The shape and length of the first flange 2-1 are matched with the second flange 3-1, and the two flanges are fastened by a connecting piece. The first flange 2-1 and the second flange 3-1 are fastened on the inner and outer sides of the mattress cover 9 by the connecting piece, clamping the mattress cover 9, and locking the first flange 2-1 and the second flange 3-1 to the mattress cover 9. The connecting piece can use a common screw (not shown in the figure). The first flange 2-1 is provided with a threaded hole 10 matched with the screw, and the second flange 3-1 is provided with a through hole 11 matched with the screw.

[0032] When the box and the fixing seat are assembled, the first flange and the second flange are fastened by the screw, so that the two flanges are locked and fitted on the inner and outer surfaces of the surrounding edge cover, and the box is fixed together with the fixing seat relative to the surrounding edge cover. The opening on the mattress cover is used to insert the fixing seat into the box.

[0033] In order to further fasten the position of the tracheal tube adapter box relative to the mattress cover, the second flange 3-1 is further provided with a plurality of conical protrusions 16 on the side fitted to the mattress cover 9. The first flange 2-1 is provided with locking holes 2-2 matched in position and number with the conical protrusions 16. When the second flange 3-1 and the first flange 2-1 are fastened, the conical protrusions 16 are inserted into the locking holes 2-2 to lock, and part of the mattress cover 9 is tensioned with the conical protrusions 16 inserted into the locking holes 2-2, preventing the tracheal tube adapter box from moving and shifting relative to the mattress cover and the mattress.

[0034] In order to connect the air supply source outside the tracheal tube adapter box, the box body 2 has a notch extending to the position of the first flange 2-1 on the downward side wall to form an outlet line port 6, and the fixed seat 3 has a notch extending to the position of the second flange 3-1 on the bottom to form an inlet line port 5. The tracheal tube adapter box 1 further comprises an outer cover 12 covering the second flange 3-1. The outer cover 12 is inserted and matched with the locking hole 14 on the second flange 3-1 through the plug-in column 13 on the inner surface, so that the outer cover 12 is locked and attached to the second flange 3-1. The outer end of the plug-in column 13 is forked to form a locking head 13-1 that can be elastically opened and closed. The locking head 13-1 is provided with a wedge-shaped guide surface on the side surface. The locking head 13-1 can be elastically closed to pass through the locking hole 14, and can be elastically opened after passing through the locking hole, so that the outer cover 12 is locked and attached to the first flange 2-1.

[0035] Since the box body and the fixed seat each have one outlet line port, and the two outlet line ports each extend to the position of the corresponding flange to form an open structure design, it is convenient to connect the air supply source outside the tracheal tube adapter box. The locking head contacts the locking hole through the wedge-shaped guide surface. During the forward movement of the plug-in column, the originally elastically opened locking head is gradually closed to pass through the locking hole. When the locking head passes through the locking hole, it is elastically opened again to recover to the initial state. The locking plug-in column makes it impossible to move backward and exit the locking hole.
