[0002] Portable tables are a cleverly designed and versatile piece of furniture, especially suitable for users with limited space or who need flexible usage scenarios. Portable tables are usually foldable, height-adjustable, and angle-adjustable, and can be easily moved to the bedside, sofa, or other places where needed to provide temporary work, dining, or entertainment.

[0003] In the prior art, such as the Chinese utility model patent with publication number CN222284983U, a multifunctional height-adjustable desk was disclosed on January 3, 2025. It realizes the height-adjusting function of the desk through the lifting rod structure and the flipping function of the desk through the clamp. Its structure is simple and the manufacturing cost is low.

[0004] However, the height adjustment function of the desk is achieved by the upper tube being fitted into the lower tube, and the adjustment and positioning between the upper and lower tubes is achieved by turning the handle. When raising or lowering the desk, it is necessary to manually loosen the handle first, then raise or lower the desk to the set height and then tighten the handle again. This operation method is quite cumbersome. Utility Model Content

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] like Figures 1 to 7 The lifting trigger mechanism 2 shown is used to trigger the pin 12 at the bottom of the gas spring 11 inside the lifting column 1 to achieve the lifting and lowering of the lifting column 1. Please refer to [reference needed] for details. Figure 1 , Figure 2 and Figure 4 The lifting trigger mechanism 2 is located at the bottom of the lifting column 1. The user triggers the pin 12 of the lifting column 1 by stepping on it, and the height of the lifting column 1 can be adjusted after triggering. It should be noted that the lifting column 1 is existing technology in this field, and its specific structure will not be described in detail here. In this embodiment of the invention, the lifting trigger mechanism 2 includes a fixed base 21, a lifting pedal 22, and a connecting member 23, specifically as follows... Figure 3 As shown, the fixed base 21 has a receiving cavity 21a inside, which, in an embodiment of this utility model, is used for the swinging of the lifting pedal 22 within it; please continue to refer to Figure 3In this embodiment of the present invention, one end of the lifting pedal 22 extends into the receiving cavity 21a, and the other end protrudes from the outside of the fixed base 21. The middle part of the lifting pedal 22 is rotatably connected to the fixed base 21. With this arrangement, by stepping on the outside of the lifting pedal 22, one end of the lifting pedal 22 in the receiving cavity 21a is raised, thereby compressing the ejector pin 12. The connecting member 23 is fixed to the top of the fixed base 21, and the ejector pin 12 of the gas spring 11 passes through the connecting member 23 and extends into the receiving cavity 21a. The connecting member 23 can limit the gas spring 11 and prevent it from shaking in the horizontal direction. In this embodiment of the present invention, as... Figure 4 and Figure 5 As shown, one end of the lifting pedal 22 that extends into the receiving cavity 21a contacts the bottom of the ejector pin 12. When the lifting pedal 22 is subjected to external force, it swings to squeeze the ejector pin 12 into the gas spring 11 to realize the action of the gas spring 11.

[0039] In the above embodiment, by rotating the lifting pedal 22 connected to the fixed base 21, the tabletop is automatically raised and lowered by stepping on the lifting pedal 22 to hold the bottom pin 12 of the gas spring 11 inside the lifting column 1. The user can adjust the height by stepping on the lifting pedal 22 and holding the tabletop with both hands. Compared with the prior art, the convenience and reliability of operation are improved.

[0040] Based on the above embodiments, such as Figure 6 As shown, the lifting pedal 22 includes a stepping part 22a, a rotating connecting part 22b connected to the stepping part 22a, and an abutting part 22c connected to the rotating connecting part 22b. The rotating connecting part 22b is rotatably connected to the fixed base 21. It should be noted that in the embodiments of this utility model, the lifting pedal 22 is generally arranged along a straight line, and it can be integrally formed, such as by casting, or the various parts can be connected together by welding.

[0041] Optionally, the specific structure of the pedal part 22a is as follows: Figure 6 As shown, side wings 22a1 are symmetrically arranged on both sides of the foot pedal 22a, and the side wings 22a1 are arc-shaped. The arc shape refers to the downward curvature of both ends of the side wings 22a1. This structure increases the contact area for the user, allowing the foot pedal 22a to be stepped on from both the front and the side. In this embodiment of the invention, the side wings 22a1 have parallel, spaced friction ribs 22a11. The friction ribs 22a11 increase the friction force when the user's foot is on the pedal, preventing slippage and improving operational reliability.

[0042] Optionally, in some embodiments of this utility model, there are various ways to rotate the lifting pedal 22 and the fixed base 21, such as using a rotating shaft connection, etc. Figure 7 As shown in one embodiment of this utility model, the side wall of the receiving cavity 21a also has two U-shaped grooves 21a1, and the rotating connecting part 22b is connected to the U-shaped grooves 21a1. Due to the opening at the top of the U-shaped grooves 21a1, it is convenient to install the rotating connecting part 22b. It is only necessary to place the two ends of the rotating connecting part 22b into the two U-shaped grooves 21a1 respectively.

[0043] In some embodiments of this utility model, the specific structure of the rotating connection part 22b is as follows: Figure 6 As shown, the cross-section of the rotating connecting part 22b is teardrop-shaped, and the width of the bottom of the rotating connecting part 22b is greater than the width of the top. The width of the U-shaped groove 21a1 is not less than the width of the bottom of the rotating connecting part 22b. In the embodiment of this utility model, the top and bottom of the rotating connecting part 22b are arc-shaped surfaces arranged opposite to each other, and the diameter of the arc at the bottom is greater than that at the top. Through this structural design, the rotating connecting part 22b can achieve more stable rotation at the bottom of the U-shaped groove 21a1. At the same time, the rotation angle of the lifting pedal 22 can be limited by the side walls of the U-shaped groove 21a1.

[0044] In this embodiment of the invention, a compression spring is also provided between the abutting part 22c and the connecting member 23. The abutting part 22c also has a protruding positioning post 22c1. One end of the compression spring is sleeved on the positioning post 22c1, and the other end is sleeved on the ejector pin 12 and abuts against the connecting member 23. The compression spring facilitates the reset of the lifting pedal 22, keeps the stepping part 22a at its highest point, and also prevents accidental activation of the ejector pin 12. By setting the positioning posts 22c1 at both ends of the compression spring, the spring can be limited, preventing its displacement.

[0045] Please continue to refer to Figure 3 In this embodiment of the invention, the connecting member 23 is plate-shaped and covers the top of the fixed base 21. The connecting member 23 has a hole 23a at its center for the ejector pin 12 to pass through. In this embodiment of the invention, by fixing the plate-shaped connecting member 23 to the top of the fixed base 21, the lifting pedal 22 can be limited, preventing the rotating connecting part 22b from disengaging from the U-shaped groove 21a1. Simultaneously, the hole 23a allows for the fixation of the bottom of the gas spring 11. Specifically, as shown... Figure 5 As shown, the bottom of the coupling 23 also has a fixing nut 24 that is screwed to the gas spring 11. By setting the fixing nut 24, the bottom of the gas spring 11 is fixed. This structural design can prevent the ejector pin 12 from shifting on the horizontal plane, thereby improving the reliability of triggering the ejector pin 12.

[0046] In embodiments of this utility model, a method such as... is also provided. Figure 8 The portable table shown includes a support base 3, the aforementioned lifting trigger mechanism 2, a lifting column 1, and a table body 4; specifically, in embodiments of this utility model, the support base 3 has various structural forms, for example, it can be as follows: Figure 8 The C-shaped structure shown can also be an I-shaped or rectangular frame structure, etc. Those skilled in the art can choose according to their needs. Casters can also be installed at the bottom of the support base 3 to further improve the ease of movement of the portable table.

[0047] The lifting trigger mechanism 2 is fixed to the support base 3. The fixing method can be achieved by screwing, although those skilled in the art can also use snap-fit ​​or welding to achieve the connection. The lifting column 1 is sleeved on the fixed base 21; the tabletop body 4 is rotatably connected to the top of the lifting column 1 to adjust the tilt angle of the tabletop body 4. This rotatable connection can take various forms, such as using a clamp as in existing technology, or other existing snap-tooth rotatable connections.

[0048] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
