This creation is a platform device that can be moved up and down according to demand, especially an adjustable lifting platform that can adjust the damping support force freely according to the bearing requirements.

Today's daily life of human beings is inextricably linked with the fields of computers, networks, communications, etc., so that we spend most of our time sitting at the computer, working, browsing, and learning, whether at work or in life. New knowledge or remote communication, etc., therefore, people are also prone to health problems due to sedentary or sitting posture.

There are many lifting platforms/lifting tables on the market that can be lifted and lowered according to demand. By sitting and standing and standing for a long time, the health problems caused by sedentary can be improved. The conventional lifting platform uses electric control. By driving the electric air pressure device to push the platform up or down to meet the demand for use; such a lifting platform not only consumes electricity, but also has high cost, and it is difficult to meet the demand due to safety considerations. There are many inconveniences in use.

In addition, there is also a lifting mechanism that does not require electric power, which is similar to a common common pneumatic chair. It is equipped with a gas pressure bar in a pivotable lifting platform structure, and the platform is formed to be lifted or fixed by controlling the locking state of the gas pressure bar. State to improve ease of use; however, such a lifting platform enhances operational convenience, but the damping support provided by the gas bar The force system is fixed. Generally, the platform needs to be maintained within a certain weight range (balanced with the damping support force), so that the user can carry out the lifting operation without taking the weight of the platform, but when the platform is over-loaded or too light, the user must give considerable Force to operate the lift, causing a burden on the use.

In view of the fact that there are still many shortcomings in the lifting platform, the creators are studying the improvement of these deficiencies and finally have this creation.

As shown in Fig. 1, the base 1 is mainly a horizontal frame, which can be used for mounting on a table top of a general table or a predetermined carrier, and the left and right sides respectively extend upwardly to form a joint portion 11 for pivoting. The arm set 3 is pivotally connected. The upper platform 2 is above the base 1 and includes a main bearing surface 201 horizontally for holding the object, and a secondary bearing surface 202 relatively lower than the main bearing surface 201. The upper platform 2 is on the main bearing surface 201. A partial position of the lower edge of the left and right sides extends downwardly from an upper connecting portion 21 for pivoting the pivot arm group 3.

The two pivot arm groups 3 are respectively pivotally connected to the upper and lower connecting portions 21, 11 on both sides. As shown in the second and third figures, each pivot arm group 3 is mainly composed of a front pivot rod 31 and a rear pivot rod 32 which are parallel to each other, and the two ends of the front pivot rod 31 and the rear pivot rod 32 are respectively pivotally connected. In the upper connecting portion 21 and the lower connecting portion 11, the pivotal positions of the rear pivots 32 are slightly higher than the pivotal positions of the front pivots 31, so that the front and rear pivots 31, 32 can smoothly pass on the base 1 and the upper platform. The two activities within the predetermined range enable the upper platform 2 to rise or fall relative to the base 1.

In a possible embodiment, the lower connecting portion 11 includes a lower connecting plate 12 and a lower locking plate 13, and a pivot is formed through the inserted locking member to pivot the front and rear pivots 31, 32 to the lower connecting plate 12. Between the lower locking plate 13 and the two sides of the pivotal positions of the front and rear pivots 31, 32, respectively, a sleeve 14 and a spacer are provided, so that the pivoting movements of the front and rear pivots 31, 32 are smoother. Moreover, the front and rear pivots 31, 32 can be dislocated by disposing the sleeve 14 on different sides of the front and rear pivots 31, 32, so as to avoid the problem of snapping during actuation, as shown in FIG. The sleeve 14 is respectively disposed on a side of the front pivot 31 adjacent to the lower connecting plate 12 to The rear pivot 32 is away from the side of the lower connecting plate 12.

Similarly, as shown in FIG. 3, the upper connecting portion 21 includes an upper connecting plate 22 and an upper locking plate 23, and a pivot is formed through the inserted locking member to pivot the front and rear pivots 31 and 32. Between the upper connecting plate 22 and the upper locking plate 23; the sleeve 24 and the spacer are respectively disposed on both sides of the pivotal positions of the front and rear pivots 31, 32 to ensure the smoothness of the pivoting operation, and the sleeve 24 They are respectively disposed on a side of the front pivot 31 adjacent to the upper connecting plate 22 and a side of the rear pivot bar 32 away from the upper connecting plate 22.

As shown in FIGS. 4-6, the two damper positioning mechanisms 4 are respectively mounted on opposite sides of the two pivot arm groups 3, and mainly include a damper expansion element 41, a control unit 42, and an adjustment assembly 43. One end of the damper expansion element 41 is mounted on the front pivot 31 of the pivot arm group 3, and the other end is coupled to the upper platform 2 via the adjustment assembly 43; the control unit 42 is mounted at a local position on the lower edge of the upper platform 2, and is provided with a control. The clue 421 is coupled to the damper telescopic element 41 for controlling the locked state (locked state or unlocked state) of the damper telescopic element 41. By controlling the state of the damper telescopic element 41, the upper platform 2 can be lifted or fixed or fixed. the height of.

The adjusting component 43 includes a slider 431, a screw 432 and a sliding slot 433. The sliding slot 433 is mounted on the lower edge of the upper platform 2, and the screw 432 is threaded in the sliding slot 433 and can be rotated by force. The slider 431 is screwed onto the screw 432 and horizontally movable in the chute 433. As shown in FIGS. 5 and 6, the user can change the position of the slider 431 by rotating the screw 432, thereby changing the support angle of the damper telescopic element 41 pivotally connected to the slider 431, thereby adjusting the damper expansion element 41 to the upper platform. 2 (vertical direction component) provides the damping support force to balance the weight of the load and reduce the negative during lifting operation Bear.

In a possible embodiment, one end of the damping telescopic element 41 is freely selectably mounted on the front pivot arm 31 or the rear pivot arm 32 of the pivot arm group 3, and the other end of the damping telescopic element 41 is freely selectably mounted on Base 1 or upper platform 2.

Referring again to Figures 7 and 8, the raised state and the lowered state of the upper platform 2 are respectively shown. In actual operation, when the control unit 42 is pressed, the damping expansion element 41 can be controlled to unlock (ie, damping). The telescopic element 41 can cooperate with the telescopic action). At this time, the user can freely operate the upper platform 2 to perform the lifting operation and adjust to the expected height. When the adjustment is completed, the touch control unit 42 is stopped, and the damper expansion element 41 is restored. The locked state (ie, the damper telescopic element 41 cannot perform the telescopic action) causes the upper platform to be fixed at a desired height and form a support.

The above structure of the present invention can be installed on a desk (or work platform) in the actual application, so that the office (or worker) can adjust the height of the upper platform 2 according to the needs of the station and the sitting to avoid Sustained sedentary and have a negative impact on the body.

Based on the above, the adjustable lifting platform of this creation can achieve stable lifting, positioning, and adjustable damping strength, in order to meet the different load requirements and reduce the operational burden, it is a novel and progressive creation. Applying for a new type of patent in accordance with the law; however, the contents of the above description are only for the preferred embodiment of the present invention, and any changes, modifications, alterations or equivalent replacements that extend from the technical means and scope of the creation are also It should fall within the scope of the patent application of this creation.
