[0008] Furthermore, an elastic pad is provided in the upper module column, the elastic pad is located below the bushing, and the sum of the thickness of the elastic pad and the connecting member is less than the thickness of the bushing.

[0009] Furthermore, a rod guide box is provided on the outer side of the upper end of the connecting member, a rod is inserted through the rod guide box and the connecting member, and a plug hole for the rod to enter is opened on the upper module column.

[0010] Furthermore, the self-locking barb includes two barbs symmetrically arranged inside the lower module column and a spring connected between the two barbs, and the barb includes two vertical rods hinged at the lower end to the inner wall of the lower module column and a strip board spanning the two vertical rods.

[0011] Furthermore, the distance between the two strips is greater than the width of the lower end of the connecting member, and smaller than the distance between the outer side walls below the two grooves of the connecting member.

DETAILED DESCRIPTION

[0026] like Figure 1 and Figure 2 As shown, the present invention includes an upper module column 1 and a lower module column 2, a weight block 12 and a connecting member 14 are arranged inside the upper module column 1, the connecting member 14 is arranged at the bottom of the upper module column 1, the weight block 12 is located above the connecting member 14, and a groove is arranged on the outside of the connecting member 14. The lower part of the weight block 12 is adapted to the inner wall size of the groove of the connecting member 14, the upper part of the weight block 12 is matched with the upper inner wall size of the connecting member 14, and an inclined surface is arranged between the lower and upper parts of the weight block 12. The weight block 12 has a certain mass, which is used to provide pressure for the connecting member 14 to slide down and to maintain the stability of the upper module column 1 and the lower module column 2 after being connected. A lower limit plate 21 and a self-locking barb 22 are provided at the top inside the lower module column 2. When the weight block 12 falls, the weight block 12 first falls into the connecting piece 14, and then the weight block 12 and the lower part of the connecting piece 14 fall into the lower module column 2, and stop after the lower end of the connecting piece 14 is blocked by the lower limit plate 21. At this time, the upper end of the self-locking barb 22 is stuck in the groove of the connecting piece 14, locking and fixing the connecting piece 14, thereby realizing the connection between the upper connecting piece 14 and the lower module column 2.

[0027] A limiting component for limiting the weight block 12 is arranged inside the upper module column 1, and the limiting component includes an upper limit plate 11 for limiting the upper part of the weight block 12 and a limiting rod 13 for limiting the lower part of the weight block 12. The upper limit plate 11 is arranged inside the upper module column 1, and the limiting rod 13 is penetrated in the upper module column 1. The weight block 12 is located between the upper limit plate 11 and the limiting rod 13, and its up and down movement is restricted by these two components. Both ends of the limiting rod 13 protrude from the upper module column 1, and one end of the limiting rod 13 is connected to a pull ring 131, through which the limiting rod 13 can be easily pulled out of the upper module column 1, and the other end of the limiting rod 13 is penetrated with a safety bolt 132 to prevent the limiting rod 13 from slipping off the upper module column 1 during transportation, causing the weight block 12 and the connecting member 14 to fall out of the upper module column 1. Remove the safety bolt 132 before pulling out the limiting rod 13. There are two limiting rods 13 , which support the weight block 12 together.

[0028] A bushing 15 is provided in the upper module column 1, and the bushing 15 is located between the connector 14 and the upper limit plate 11, and the weight block 12 is located in the bushing 15. An elastic pad 16 is provided in the upper module column 1, and the elastic pad is located below the bushing 15. The upper end of the connector 14 squeezes the elastic pad 16, so that the friction between the upper end of the connector 14 and the elastic pad 16 locks the connector 14 in the upper module column 1. In addition, the sum of the thickness of the elastic pad 16 and the connector 14 is less than the thickness of the bushing 15, so that the weight block 12 will not interfere with the upper end of the connector 14 during the falling process.

[0029] A rod guide box 141 is provided on the outer side of the upper end of the connector 14, and a rod 142 is inserted through the rod guide box 141 and the connector 14. A hole is provided on the side of the rod guide box 141 away from the connector 14 for the outer end of the rod 142 to pass through, and the inner end of the rod 142 extends flatly into the interior of the connector 14. A socket is provided at the lower part of the upper module column 1 for the outer end of the rod 142 to enter. After the upper module column 1 and the lower module column 2 are connected, the outer end of the rod 142 extends into the socket to fix the connector 14 to the upper module column 1. The inner end of the rod 142 is an inclined surface, and the inclined surface of the inner end of the rod 142 matches the inclined surface of the weight block 12. The insertion rod 142 is provided with a ridge, the diameter of which is larger than the size of the insertion hole of the lower module column 2 and also larger than the size of the through hole of the connector 14 for inserting the insertion rod 142, so that the insertion rod 142 will not fall out of the insertion rod guide box 141. There are two insertion rod guide boxes 141, which are symmetrically arranged at both ends of the connector.

[0030] The connecting member 14 is U-shaped as a whole, and has two grooves, which are symmetrically arranged on both sides of the connecting member 14. The outer wall below the groove of the connecting member 14 is an inclined surface extending inward, and the lower part of the connecting member 14 is an inverted trapezoidal shape to prevent its lower end from interfering with the upper end of the self-locking hook 22 during the connection process.

[0031] The self-locking hook 22 includes two hooks symmetrically arranged on both sides of the lower module column 2 and a spring 223 connected between the two hooks. The hook includes two vertical rods 221 with lower ends hinged to the inner wall of the lower module column 2 and a strip 222 straddling the upper ends of the two vertical rods 221. The strip 222 is used to clamp the groove of the connector 14. A connecting ear plate 23 is connected inside the lower module column 2, and the lower end of the self-locking hook 22 is hinged to the connecting ear plate 23. There are two springs 223, one spring is arranged between the vertical rods 221 corresponding to the two hooks. The spring 223 makes the distance between the upper ends of the two self-locking barbs 22 larger than the width of the lower end of the connector 14, so that the lower end of the connector 14 can enter between the two self-locking barbs 22; at the same time, it is smaller than the distance between the outer side walls below the two grooves of the connector 14, so that when the lower end of the connector 14 contacts the lower limit plate, the upper end of the self-locking barb 22 can be clamped in the groove of the connector 14 under the tension of the spring 223. The inner side of the strip 222 is provided with an inclined surface, which matches the inclined surface extending outward from the outer wall below the groove of the connector 14, thereby ensuring that the connector 14 can smoothly slide between the two self-locking barbs 22, and the strip 222 is clamped into the groove by the tension of the spring.

[0032] An unlocking rope 224 is arranged outside the self-locking barb 22, and an unlocking hole for the unlocking rope 224 to pass through is opened on the lower module column 2. The unlocking rope 224 is inserted into the unlocking hole, and an unlocking ring 225 is connected to the outer end of the unlocking rope 224. The unlocking rope 224 is pulled outward through the unlocking ring 225 to release the locking of the self-locking barb 22 on the connecting member 14, and disconnect the upper module column 1 from the lower module column 2.

[0033] There are two lower limit plates 21 to stably support the connecting piece 14. The position of the lower limit plate 21 is higher than the position of the connecting ear plate 23, and lower than the position of the strip plate 222 when the self-locking barb 22 is in the vertical state. The width of the lower limit plate 21 is smaller than the distance between the two vertical rods 221 of the self-locking barb 22 to prevent the self-locking barb 22 from interfering with the lower limit plate 21 when rotating. The position of the spring 223 is lower than the lower limit plate 21 to prevent interference with the connecting piece 14.

[0034] A positioning ring 3 is provided between the upper module column 1 and the lower module column 2. When the upper module column 1 is mounted on the lower module column 2, the positioning ring 3 ensures accurate alignment and positioning of the two.

[0035] When in use, the positioning ring 3 is installed on the upper end of the lower module column 2, and then the lower end of the upper module column 1 is installed on the positioning ring 3. Then the safety bolt 132 is pulled out, and then the limit rod 13 is pulled out. Figure 3As shown, the weight block 12 falls downward into the connecting member 14. After the inclined surface of the weight block 12 contacts the insertion rod 142, the weight block 12 and the connecting member 14 slide downward together under the action of inertia and gravity, and then the lower end of the connecting member 14 enters between the two self-locking hooks 22. As the connecting member 14 slides downward, the lower inclined surface of the connecting member 14 squeezes the two self-locking hooks 22 on both sides. Figure 4 As shown, when the lower end of the connecting piece 14 contacts the upper end of the lower limit plate 21, the self-locking hook 22 is engaged in the groove of the connecting piece 14 under the tension of the spring, completing the connection between the lower module column 2 and the connector 14. Afterwards, the weight block 12 continues to move downward until it contacts the inner bottom of the connector 14. During the downward movement of the weight block 12, the weight block 12 presses the insertion rod 142 outward, and the outer end of the insertion rod 142 enters the insertion hole of the upper module column 1, connecting the connecting piece 14 to the upper module column 1.

[0036] The unlocking rope 224 is pulled outward to unlock the connection between the self-locking hook 22 and the connector 14, thereby disconnecting the upper module column 1 and the lower module column 2.
