為使本發明的目的、技術方案、及優點更加清楚明白，以下參照附圖並舉實施例，對本發明進一步詳細說明。請參考圖1至圖10進行閱讀。 In order to make the purpose, technical solution, and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples. Please refer to Figure 1 to Figure 10 for reading.
在本發明中，雙向啟閉門軸可以安裝在門扇的上部或下部。安裝在上部和下部的雙向啟門軸的結構可以一致，也可以不一致，不一致的原因是考慮重力的作用，如果使用液壓緩衝機構，就最好要考慮在垂直於地面的方向上，上部是儲油腔，下部是受壓油腔，因為受壓油腔要保護沒有空氣，如果受壓油腔設置在上部，有可能有空氣進入，而空氣的壓縮彈性大，將降低液壓緩衝的緩衝功效。 In the present invention, the bidirectional opening and closing door shaft can be installed on the upper or lower part of the door leaf. The structure of the two-way door opening shaft installed on the upper and lower parts can be consistent or inconsistent. The reason for the inconsistency is to consider the effect of gravity. If a hydraulic buffer mechanism is used, it is best to consider it in the direction perpendicular to the ground. The upper part is the storage space. The lower part of the oil chamber is the pressurized oil chamber, because the pressurized oil chamber must be protected from air. If the pressurized oil chamber is set at the upper part, air may enter, and the compression elasticity of air is large, which will reduce the buffering effect of the hydraulic buffer.

In actual use, when the user opens and closes the door leaf, there is an external force to rotate the output shaft 1203, causing the chute column 12 to rotate as a whole. Since the central shaft 9 and the shaft sleeve 5 are connected with a synchronous axial sliding fit, the shaft sleeve 5 and the outer sleeve 6 and the second cover 14 are fixedly connected, so when the chute column 12 rotates, the first chute 1201 and the second chute 1202 rotate and shift, driving the first drive shaft 901 in the first chute 1201 The middle and second drive shafts 902 are displaced upward in the first chute 1201, as shown in Figure 10 from left to right, driving the central shaft 9 to only move axially. When the first drive shaft 901 and the second drive shaft When 902 is located at the lowest point of the V-shape of the first chute and the second chute, whether the first drive shaft 901 or the second drive shaft 902 rotates left or right, the central shaft 9 can move axially upward, and the piston can also move upward. Following the movement and pressing the return spring 7 to store energy, the hydraulic oil in the oil storage chamber 24 flows to the pressurized oil chamber 23 through the one-way valve 22. When the first drive shaft 901 and the second drive shaft 902 are located in the first slide groove and the second slide groove, When the V-shaped highest point of the groove is parallel to the horizontal end face of the groove, the central shaft 9 does not move axially. When running to the groove section, the sliding sleeve 10 is pressed by the return spring 7 and is engaged and positioned, and the circumferential movement of the central shaft is limited. The fixed angle stays, and the return spring 7 is in the energy storage state. When the output shaft 1203 rotates, the positioning sleeve 20 also rotates, and the positioning ball 15 breaks away from the positioning hole 1401 and slides along the hollow step surface of the second cover 14.

In the middle process, the positioning ball 15 moves on the hollow step of the second cover 14 Then, the positioning spring 16 can push the lower ball of the positioning ball 15 into the positioning hole 1401 to achieve 0 degree positioning. When the piston 8 moves downward, the one-way valve on the piston closes, pushing the pressure oil chamber 230 The hydraulic oil flows to the oil storage chamber 24 through the oil return path provided by the central shaft 9. The oil in the pressurized oil chamber 23 can pass through the gap between the outer cylinder of the first end 9001 of the central shaft and the first cover such as the shaft sleeve 5. The gap flows to the hole 903 of the central shaft, and then flows to the oil storage chamber 24 through the oil return hole 904 on the hole. The user can control the return speed of the hydraulic oil to achieve buffer closure, and twist the speed adjustment screw 2 through the adjustment wheel 1 to change the degree needle. The speed-regulating oil needle 4 of the rod is inserted into the hole 9 of the central shaft to an insertion depth, and the gap between the speed-regulating oil needle 4 and the hole 903 is changed to control the flow of hydraulic oil and realize the adjustability of the closing speed.

Since the central shaft 9 and the sleeve 5 are connected with a synchronous axial sliding fit, the sleeve 5, the outer sleeve 6 and the second cover 14 are fixedly connected, so when the chute column 12 rotates, the first chute 1201 and the second chute 1202 are rotated and displaced, driving the first driving shaft 901 in the first chute 1201 and the second driving shaft 902 in the first chute. The upward shift in the chute 1201, as shown in Figure 11 from right to left, drives the central shaft 9 to move only in the axial direction. When the first drive shaft 901 and the second drive shaft 902 are located in the first chute and the second chute, When the V-shaped groove is at its lowest point, whether the first drive shaft 901 or the second drive shaft 902 rotates left or right, the central shaft 9 can move axially upward, and the piston will also follow the movement and press the return spring 7 to store energy. The hydraulic oil in the oil storage chamber 24 flows to the pressurized oil through the one-way valve 22 Cavity 23, when the first drive shaft 901 and the second drive shaft 902 are located in the grooves parallel to the horizontal end surfaces at the highest V-shaped parts of the first chute and the second chute, the central shaft 9 does not move axially and runs to In the groove section, the sliding sleeve 10 is pressed by the return spring 7 and is engaged and positioned. The circumferential movement of the central axis is limited and stays at a fixed angle. The return spring 7 is in an energy storage state. When the output shaft 1203 rotates, the positioning sleeve 20 also rotates. The positioning ball 15 detaches from the positioning hole 1401 and slides along the hollow step surface of the second cover 14. During the process of the positioning ball 19 disengaging from the positioning hole 1401, the positioning ball 19 moves downward to compress the positioning spring 16 to store energy. When the output shaft 1203 moves left When turning 90 degrees to the right or right, the positioning spring 16 can push the upper sphere of the positioning ball 19 to extend into the positioning hole 1401 to achieve 90-degree enhanced positioning; When the two-way opening and closing door shaft is in the open position, that is, when the first drive shaft 901 and the second drive shaft 902 are located in the grooves parallel to the horizontal end surfaces at the highest V-shaped parts of the first chute and the second chute, the opposite direction is opened. Rotate the output shaft 1203 in the direction to cause the chute column 12 and the positioning sleeve 20 to rotate as a whole. When the drive shaft 11 slides to the inclined section of the V-shaped chute, the return spring 7 releases energy to drive the piston 8 and the central shaft 9 to move axially downward. , the second drive shaft 902 and the first drive shaft 901 also move downward, sliding to the lowest point at the bottom of the V-shaped chute through the inclined section of the V-shaped chute, so that the chute column 12 and the positioning sleeve 20 rotate and reset as a whole to achieve automatic closing. , during this rotation process, the upper sphere of the positioning ball 15 breaks away from the positioning hole 1401 to release the 90-degree engagement positioning, and presses the positioning spring 16 to store energy. During the intermediate process, the positioning ball 15 moves around the hollow step surface of the second cover 14 After sliding, the positioning spring 16 can push the upper part of the positioning ball 15 into the positioning hole 1401 to achieve 0 degree positioning. When the piston 8 moves downward, the one-way valve 22 on the piston closes, pushing the hydraulic pressure of the pressurized oil chamber 23 The oil flows to the oil storage chamber 24 through the oil return path set up in the central shaft 9. The oil in the pressurized oil chamber 23 can flow to the hole 903 of the central shaft through the oil return hole 904, and then passes between the central shaft and the first cover or the shaft sleeve. The gap flows to the oil storage chamber 24. The user can control the return speed of the hydraulic oil to achieve buffer closure by twisting the speed-regulating screw 2 through the adjusting wheel 1, changing the insertion depth of the speed-regulating oil needle 4 of the conical needle bar into the hole 9 of the central shaft, and changing the distance between the speed-regulating oil needle 4 and The gap between the holes 903 controls the flow rate of the hydraulic oil and realizes the adjustability of the closing speed.
