Description of the invention (4) The rotation direction of the rotary joint can be lifted and lowered in the cylinder chamber filled with the casing of oil Zhao, and the spring 12 is used as an intermediary to impart elasticity under the piston ^, and the lower section is plugged with one end 13 screwed. A path lib is formed at the lower inner portion of the aforementioned piston π to cause the oil body to rise when descending, and is provided with a check valve function that can be used as an intermediary to prevent the backflow phenomenon when the ball 14 is used as an intermediate. The screw shaft 3b of the pivot shaft 3 and the screw portion 3d of the piston 11 should preferably increase the twist angle, such as a helical gear. Around the appropriate position of the aforementioned pivot 3, a straight hole is formed in the screw hole 1 d of the housing 1 through the position of the relative hook groove 3c, and is connected by a nut, and the pivot 3 and the housing 1 are rotated slightly at one time. It can be fixed in a state, so that when the door is closed, it can be adjusted to be elastically close to the door frame 30.

Description of the Invention (5) The pivot 3 is embedded in the connecting member 5 At the same time, the key piece 6a formed on the outer side of the mounting plate 6 of the door 20 is consolidated into the key groove formed in the upper section of the housing 1 to be fitted together, and the pivot 3 is connected by the nut 16 at the upper section. Fixed while completing the installation. Then before the installation, 'the pivot 3 is rotated slightly to make the piston ^ slightly lowered, and through the screw hole 1 (1 formed on the upper side of the housing 1 to be consolidated with bolts', and then embedded in the stern shaft The hook groove 3e of 3 makes the housing 1 in a non-rotating state. After the door 20 is installed, the aforementioned screw hole Id is opened to release the fixation of the housing 1 and the pivot 3, and the spring 12 can be used. The elasticity is used for the original restoring force of the housing 1 to be rotated to the original position, so that the door 20 is pressurized in the door frame 30, so that the door 20 and the door frame 30 can be tightly closed and can be closed. Installation is completed through the aforementioned simple installation procedure According to the present invention, when the door 20 is to be opened, the pivot 3 is fixed to the mounting plate 7 fixed to the door frame 30, so it does not rotate, and the shell fixed to the door 20 is connected with the mounting plate 6. I want to rotate 1 with the key lb '11 a and the piston η connected to the shell 1 also rotates together, so that the piston 11 is combined with the screw shaft 11 a of the pivot 3, so the screw 11 can be used to lower the piston 11 At the same time as the oil body squeezes the bomb 12 while lowering, the door 20 is pressed with an appropriate pressure, and the door is opened.

Description of the invention (6) The adjustment of the control valve 4 is performed by rotating the adjustment rod 4a. In order to adjust the space after the oil body is discharged, the opening speed of the door can be adjusted. On the other hand, when the door 20 is to be closed, the piston 11 is raised by the spiral joint by the opposite effect of the foregoing, that is, the inversion of the housing 1. At the same time, it is raised by the elastic force of the spring 12, at this time in the center of the piston 丨 丨The aforementioned passage le is blocked by the suction force of the spherical body 14 and the piston and the surrounding oil body pass through the oil passage 2a and flow into the cylinder chamber ic below. Due to the narrow space of the oil passage 2a, the oil tanker is slowly discharged. Therefore, the door 20 will not be closed immediately, but will be closed slowly at an appropriate speed by the pressure of the oil body. The closing speed is the same as the aforementioned opening procedure, and the adjustment rod 4a is rotated to adjust the adjustment rod 4a ' According to this, the space formed after the oil body is discharged can be adjusted, and the closing speed can be adjusted.

And noise. That is, the door 20 can be closed at an appropriate speed by controlling the oil body, and at the same time, the closing speed before closing can be reduced, and the door can be closed smoothly. FIG. 8 shows another embodiment of the present invention. In this example, the contact systems forming the pivot shaft 3 and the piston 11 are symmetrical and combinable spiral sliding surfaces 31 and 111 ′ when the housing 1 rotates, As the spiral sliding surfaces 31 and U1 contact each other, the piston 11 is lowered, and the door can be closed as described above, and the function is the same as that described above. This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 10 A7 B7 V. Description of the invention (7) Figure 9 is another embodiment of the present invention. The contact of the piston 11 is a symmetrical and combinable inclined sliding surface u, 112. When the housing 1 rotates, the piston 11 descends with the mutual contact of the inclined sliding surface%, ιΐ2, and the door can be closed as described above. This function is the same as the above. In addition, in the present invention, the structure of the housing structure forms the left side of the protruding door 20, because this structure can also be installed on an existing door, and the housing can also be used when making a new door. The structure is placed inside the door so that its appearance does not see the structure. In this way, the present invention is used for the piston that can move up and down when the door is opened and received the pressure of the oil body to operate, so it can be opened and closed under appropriate controlled pressure to improve efficiency, and it can be easily operated to adjust the switching speed, etc. The use surface not only has convenient effects, but also can be easily installed on the existing door without damaging the appearance, minimizing the area of the exposed space, and exerting the effect of making the appearance beautiful. ---.---, ------ Installation -------- Order.
