Another main object of the present invention is that the mechanism for adjusting the height of the table can achieve the purpose of reducing vibration and noise, enabling the table to rise and fall smoothly, and thereby extending the life of the table. A further main object of the present invention is to reduce the energy required when the table is raised through the adjustable telescopic air pressure rod, and to slowly descend by gravity without the need for additional energy when lowering the height of the table. And the adjustable height of the table can also increase the stability of the height of the table. To achieve the above object, the main components of the present invention include a table, a power device, a transmission device and two adjustable telescopic air pressure rods. The table includes a table top, two mobile brackets, and two fixed brackets, wherein the bottom ends of each mobile bracket can be inserted into the opposite fixed brackets. Two stable wheels are suitably arranged at the bottom end of each moving bracket, and the stability wheels are in contact with the inner wall of the fixed bracket; and the top end of each fixed bracket is provided with an external stability wheel, and the external stability wheel is in contact with the moving bracket. The function of the stabilizing wheel and the outer stabilizing wheel is that when the moving bracket is moving, it can move in a stable manner. 7 1227117 In the embodiment, the power unit uses a motor and a driving gear to generate mechanical energy. The transmission device includes a rotating shaft, a transmission gear, two adjusting gears and two racks. The driving gear is fixed on the rotating shaft and connected with the driving gear. The two adjusting gears are fixed at both ends of the rotating shaft. The two racks are each provided on a moving support, wherein each rack is connected to the opposite adjustment gear, so that when the adjustment gear is rotating, the moving support moves up and down accordingly. The bottom ends of the two adjustable telescopic air pressure rods are fixed on the opposite fixed bracket, and the top ends of the two adjustable telescopic air pressure rods are fixed on the opposite mobile bracket. The adjustable telescopic air pressure rods have a pressure release plug. At the time, the adjustable telescopic air bar can be adjusted in length. The controller for adjusting the lifting of the table can control the rotation of the motor at the same time. In addition, it also controls whether the pressure release bolt is pressed so as to adjust the length of the adjustable telescopic air stick. [Embodiment] In order to make your reviewing committee better understand the technical content of the present invention, two preferred specific embodiments are described below. In the following, please refer to FIGS. 1 to 3 together for the first embodiment. The main components of the height-adjustable table 10 of the present invention include a table 20, a power unit 40, a transmission unit 50, and two adjustable telescopic air bars 70. 8 1227117 The table 20 includes a table top 30, two mobile brackets 32, and two fixed brackets 34. The top ends of the two moving brackets 32 are fixed to the table top 30, and the two fixing brackets 34 can be placed on the ground. It should be noted that each of the fixing brackets 34 has a receiving groove 342, so that the bottom end of each moving bracket 32 can be inserted into each of the opposite receiving grooves 342. Since each fixing bracket 34 has an accommodating slot 342, each fixing bracket 34 forms an inner wall 343. Two bottom stabilizing wheels 61 are provided at the bottom end of each moving bracket 32, and the stabilizing wheels 61 are in contact with the inner wall 343 of the fixing bracket 34; and an outer stabilizing wheel 62 is provided at the top of each fixing bracket 34, and The outer stabilizing wheel 62 is in contact with the moving bracket 32. The role of the stabilizing wheel 61 and the outer stabilizing wheel 62 is that when the moving bracket 32 is moving, it can move in a stable manner, especially to ensure that the moving bracket 32 can move in a straight line when moving, so that it can reduce vibration and noise. , Or the pressure caused by the moment of resistance (the weight carried by the mobile bracket 3 2 may not necessarily pass through the center of gravity of the mobile bracket 3 2); the material used for the stabilizer wheel 6 1 and the outer stabilizer wheel 6 2 is preferably not rigid, such as rubber. The power unit 40 uses, for example, a motor 41 and a driving gear 42 to generate mechanical energy. The power unit 40 is fixed at a suitable place on the table 20. For example, in this embodiment, the table 20 further includes a horizontal frame 38, and both ends of the horizontal frame 38 are fixed to two fixing brackets 34, so that the power unit 40 is fixed to the horizontal frame 38. . 9 1227117 The main purpose of the transmission device 50 is to receive the mechanical energy from the power unit 40 so as to move the two moving supports 32 to adjust the height of the table 30. The transmission device 50 is connected to two moving supports 32. In this embodiment, the transmission device 50 includes a rotating shaft 51, a transmission gear 52, two adjustment gears 53, and two racks 54. The transmission gear 52 is fixed on the rotating shaft 51 and is connected with the driving gear 42 so that the driving gear 42 rotates when the driving gear 42 rotates, so that the rotating shaft 51 also rotates. The two adjusting gears 5 3 are fixed to both ends of the rotating shaft 51. The two racks 5 4 are each disposed on the moving bracket 3 2, and each of the racks 5 4 is connected to the opposite adjustment gear 5 3 so that when the adjustment gear 53 is rotated, the moving bracket 32 moves up and down accordingly. That is, when the motor 41 is rotated, the rotating shaft 51 drives the two adjustment gears 53 to rotate, so the moving bracket 32 can move up and down due to the rack 54. Therefore, the rotation direction of the motor 41 is preferably forward and reverse ( For example, it corresponds to moving the bracket 3 2 up or down). If the motor 4 1 can only rotate in one direction, other mechanisms (such as a gear set) are required to change the direction of rotation of the transmission gear 5 2, but this design is too complicated. It should also be noted that the motor 41 can also only have the power to raise the moving bracket 32, such as the force of forward rotation. The reason is that when the moving bracket 32 is lowered, it is actually because of the relationship between the adjustable telescopic air bar 70 and the motor. 4 1 It is not necessary to provide a force of 1227117 for reversing (lowering the mobile bracket 3 2). For details, please refer to the following. The bottom ends of the two adjustable telescopic air pressure bars 70 are fixed to the opposite fixed bracket 34, and the top ends of the two adjustable telescopic air pressure bars 70 are fixed to the opposite mobile bracket 32. Among them, the adjustable telescopic air pressure bar 70 has a pressure release plug 71, which is released when When the pressure pin 71 is pressed, the telescopic air pressure rod 70 can be adjusted to adjust the length. Adjustable telescopic air pressure stick 70 The most commonly used occasions such as adjustable office chairs, when the user wants to lower the height of the office chair chair surface, press the control rod, and at this time can be adjusted by the weight of the human body The telescopic air bar 70 was lowered. When the user wants to increase the height of the office chair, the user still has to press the control stick. At this time, the user must leave the office chair, so that the high-pressure gas (previously formed by the pressure of the human body) will store the high office chair. Push on the surface. Pressing the control rod on the office chair means pressing the pressure release bolt 7 1. The pressure-releasing plugs 71 of each adjustable telescopic air pressure rod 70 are controlled by two pressure-releasing starting mechanisms 75, that is, each pressure-releasing starting mechanism 75 is in contact with the opposite pressure-releasing plug 71, so as to control the pressure-releasing plug. 7 1 is pressed. In this embodiment, the pressure relief starting mechanism 7 5 is a solenoid valve 7 5 1. Please refer to FIG. 3 for the relationship between the controller 80 and the motor 41 and the solenoid valve 7 5 1 (not shown in FIGS. 1 to 2). The connection between the controller 80 and the motor 41 and the solenoid valve 751 are not shown. The connection line 9 5 is not shown to reduce the complexity of the drawing). The power source 9 5 provides power to the control 11 1227117 device 8 O, the motor 41 and the solenoid valve 7 5 1. The power source 9 5 can be obtained, for example, from a household electrical plug or a battery. The power supply controller 80 basically includes "up" and "down" buttons. For example, when the user presses the "up" button, the motor 41 rotates forward, and when the "up" button is pressed, the electromagnetic The valve 7 5 1 is activated, so that the pressure release plug 7 1 is pressed. At this time, the upward force of the moving bracket 3 2 provides energy in addition to the motor 4 1, and also includes an adjustable telescopic air bar 7 0. The horsepower of the motor 41 can be reduced. In another situation, when the user presses the "down" button, the motor 41 reverses, and at the same time when the "down" button is pressed, the solenoid valve 7 5 1 is activated, so that the pressure release 71 When pressed, the downward force of the mobile stand 32 in addition to providing power to the motor 41 also includes the weight given to the mobile stand 32, such as the desktop 30 and the screen 91 placed on the desktop 30, the carrier 31 and The computer host 92 placed on the carrier 31, but it should be noted that the moving bracket 32 does not actually need the energy provided by the motor 41, that is, the weight given to the moving bracket 32 is used for adjustable telescoping. The air pressure rod 70 can be used, so when the user presses the "down" button, the solenoid valve 7 51 is activated, and the motor 41 does not need to be reversed although it is reversed. The function of the adjustable telescopic air bar 7 0 is to provide the upward force of the moving bracket 32 and the slow 1 2 1227117 punching force when the moving bracket 32 is downward. When the table 20 is at a standstill, the pressure release plug 7 1 is not pressed, so the adjustable telescopic air bar 70 can support the force pressed against the moving bracket 32. Please refer to FIG. 4 for the second embodiment. The main difference from the first embodiment is that the installation position of the adjustable telescopic air bar 70 is different. Two auxiliary racks 3 6 are installed at the appropriate place on the desktop 30 (only one auxiliary rack 3 6 can be seen in the side view), for example, near the front edge of the desktop 30, and the top of the adjustable telescopic air bar 70 is fixed to the opposite side On the auxiliary frame 3 6, the bottom end is fixed to the opposite fixed bracket 34. Similarly, the function of the adjustable telescopic air pressure rod 70 is similar to that of the first embodiment, so it will not be repeated here. To sum up, the present invention, regardless of its purpose, means, and effect, shows its characteristics that are quite different from those of the conventional technology. This is a major breakthrough. I implore your reviewers to make a clear observation and grant a quasi-patent as soon as possible. Real sense. It should be noted that the above-mentioned embodiments are merely illustrative for explaining the principle of the present invention and its effects, and are not intended to limit the scope of the present invention. Anyone skilled in the art can modify and change the embodiments without departing from the technical principles and spirit of the present invention. The scope of protection of the rights of the present invention shall be as described in the patent application scope mentioned later. [Schematic description] 13
