Example 1:
referring to fig. 1-2, the embodiment provides a cross-shaped placement frame for placing oxygen tubes, which comprises a central ring d5, four telescopic tubes and four positioning members.
Four telescoping tubes are first telescoping tube b1, second telescoping tube b2, third telescoping tube b3 and fourth telescoping tube b4, respectively, and four positioning members are first positioning member a1, second positioning member a2, third positioning member a3 and fourth positioning member a4, respectively. A first positioning member a1 is mounted on the outer end of first extension tube b1, a second positioning member a2 is mounted on the outer end of second extension tube b2, a third positioning member a3 is mounted on the outer end of third extension tube b3, a fourth positioning member a4 is mounted on the outer end of fourth extension tube b4, and the inner end of first extension tube b1, the inner end of second extension tube b2, the inner end of third extension tube b3 and the inner end of fourth extension tube b4 are all mounted on center ring d 5.
The four bellows are connected by a central ring d 5. The telescopic tube comprises an inner tube b13 and an outer tube b11 which are coaxially arranged, and the inner tube b13 is axially movably arranged in the middle of the outer tube b 11. In this embodiment, the connection position of the central ring d5 and the telescopic tube is the inner end of the outer tube b11, and the inner tube b13 axially moves at the outer end of the outer tube b11 to control the telescopic motion of the telescopic tube. The corresponding connecting position of the positioning piece and the telescopic pipe is the outer end of the inner pipe b 13. (in this embodiment the inner end is the end near the center ring d5 and the outer end is the end far from the center ring d 5)
The first telescopic tube b1, the second telescopic tube b2, the third telescopic tube b3 and the fourth telescopic tube b4 can have the same length or different lengths through telescopic change. A first positioning piece a1, a second positioning piece a2, a third positioning piece a3 and a fourth positioning piece a4 are all positioned on the side wall of the water cylinder so as to stabilize the positions of the outer ends of the four extension tubes on the side wall of the water cylinder, and further the inner ends of the four extension tubes jointly support a central ring d 5. The center ring d5 is sleeved on the oxygen tube, and the oxygen tube is partially fixed relative to the water tank at the position of the center ring d 5. The center ring d5 is located above the water surface, the center ring d5 is supported by the four telescopic pipes and can support and locate the oxygen tube, so that the part of the oxygen tube between the air inlet end and the center ring d5 is located above the center ring d5 or outside the water cylinder and does not sink into the water, the length of the oxygen tube in the water is almost fixed, the air outlet end of the oxygen tube is always located in the water and above the bottom mud, the contact between the oxygen tube and the bottom mud is reduced, and the integrity of the bottom mud is improved. In addition, due to the positioning effect of the central ring d5 on the oxygen pipe, although most of the oxygen pipe can be outside the water tank, the oxygen pipe cannot completely leave from the water tank due to the elasticity and gravity, and the part of the oxygen pipe between the air outlet end and the central ring d5 cannot swing to an excessive extent in the water tank, so that the air outlet end is always positioned in the water tank.
In addition, the different lengths of the first telescopic tube b1, the second telescopic tube b2, the third telescopic tube b3 and the fourth telescopic tube b4 correspond to different positions of the central ring d5 in the water tank, so that the position of the air outlet end of the oxygen tube in the water tank can be changed, for example, the air outlet end of the oxygen tube in the embodiment can be arranged at the center of the water tank.
In the embodiment, the inner end of the outer pipe b11 is provided with a mounting plate b17 through a screw, and the inner end of the outer pipe b11 is connected with the outer wall of the center ring d5 through a mounting plate b 17. The mounting plate b17 also prevents water from flowing into the outer tube b11 from the inner end of the outer tube b 11. The shape of the mounting plate b17 is matched with that of the outer wall of the center ring d5, so that the contact area between the mounting plate b17 and the center ring d5 is increased, and the connection strength between the mounting plate b17 and the outer wall of the center ring d5 is ensured.
In order to reduce the damage of the center ring d5 to the outer wall of the oxygen tube, the center ring d5 is made of rubber, and the center ring d5 is connected with the mounting plate b17 through adhesive. The center ring d5 holds the oxygen tube tightly by friction and deformation to restrain the oxygen tube from moving at the center ring d 5.
Correspondingly, the inner ends of the four extension tubes can respectively promote the central ring d5 to deform at different positions so as to enlarge the variable range of the relative positions between the four positioning pieces, and the deformation amount of the central ring d5 can be increased, thereby enhancing the holding effect on the oxygen tube.
The water cylinder in the embodiment is a rectangular water cylinder, the first extension tube b1 and the third extension tube b3 are coaxially arranged, the second extension tube b2 and the fourth extension tube b4 are coaxially arranged, the axis of the first extension tube b1 is perpendicular to the axis of the second extension tube b2, and the first extension tube b1, the second extension tube b2, the third extension tube b3 and the fourth extension tube b4 are positioned in the same plane. In the embodiment, the first positioning piece a1, the second positioning piece a2, the third positioning piece a3 and the fourth positioning piece a4 are all two-claw anchors, the lengths of the first telescopic tube b1, the second telescopic tube b2, the third telescopic tube b3 and the fourth telescopic tube b4 are adjusted, so that the sum of the lengths of the first telescopic tube b1 and the third telescopic tube b3 is equal to or slightly smaller than the length of the water cylinder, and the sum of the lengths of the second telescopic tube b2 and the fourth telescopic tube b4 is equal to or slightly smaller than the width of the water cylinder, and therefore the first positioning piece a1, the second positioning piece a2, the third positioning piece a3 and the fourth positioning piece a4 respectively grasp the outer walls in the front, the back, the left and the right directions at the top opening of the. The position of the central ring d5 in the water cylinder is determined by the specific length of the four bellows, so that in this embodiment the inner tube b13 is positioned radially in the middle of the outer tube b11, the outer wall of the inner tube b13 is provided with graduation marks, the inner tube b13 is axially displaced at the outer end of the outer tube b11, the specific length of the respective bellows is read by the outer end of the outer tube b11 being aligned with the graduation marks, and the position of the stabilizing spacer relative to the outer tube b11 in the radial direction is simultaneously stabilized.
For example, in this embodiment, center ring d5 is located at the center of the water cylinder, and first bellows b1 and third bellows b3 are equal in length, and second bellows b2 and fourth bellows b4 are equal in length, and the four bellows are in the horizontal plane. Compared with the telescopic pipes, the central ring d5 has smaller size, and the deformation of the central ring has negligible influence on the connection state and the position of the four telescopic pipes and the outer wall of the water tank.
Additionally, in the embodiment, the outer wall of the inner tube b13 is provided with a guide block along the axial direction, the inner wall of the outer tube b11 is provided with a guide groove along the axial direction, the guide block is in sliding contact with the guide groove, so that the inner tube b13 is positioned in the middle of the outer tube b11 along the circumferential direction and the radial direction at the same time, and the inner tube b13 only moves relative to the outer tube b11 along the axial direction.
In the oxygen pipe air supply process, the lengths of the four telescopic pipes need to be kept unchanged to stabilize the position of the central ring d5 in the middle of the water tank, and therefore the telescopic pipes need a self-locking function.

The nut b18 is fixed at the inner end of the inner tube b13, the nut b18 is screwed on the screw rod b14, and the screw rod b14 passes through the nut b18 to the middle of the inner tube b 13. Since the inner tube b13 can only move axially in the middle of the outer tube b11, the nut b18 can only move axially in the middle of the outer tube b11, and the nut b18 cannot rotate in the middle of the outer tube b11 when the screw rod b14 rotates in the middle of the outer tube b 11. The rotating speed of the screw b14 and the transmission ratio between the screw b14 and the nut b18 determine the axial moving speed of the nut b18 in the middle of the outer tube b11, and the axial moving speed of the nut b18 in the middle of the outer tube b11 determines the axial moving speed of the inner tube b13 relative to the outer tube b11, namely the telescopic speed of the telescopic tube. After the motor b15 stops working, the self-locking force between the screw rod b14 and the nut b18 can fix the length of the telescopic pipe.
