[0041] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0043] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0044] In order to solve the problem in the prior art that alignment is often difficult when the lower end of the height adjustment member is installed in the installation hole of the support base, resulting in a time-consuming and labor-intensive process of fixing the loading platform and affecting work efficiency, the utility model provides an adjustable carrier.

[0045] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] like Figure 1-4 As shown, an embodiment of the present invention provides an adjustable carrier, which includes a loading platform 1, at least three support structures 2 arranged on the loading platform for supporting the loading platform, the support structure 2 including a height adjustment member 21, a support seat 22 and a pre-positioning magnetic member 23, the pre-positioning magnetic member 23 is arranged on the lower surface of the loading platform 1, the height adjustment member 21 is passed through the loading platform 1 and the pre-positioning magnetic member 23 and has a first end 2111 protruding from the pre-positioning magnetic member, the height adjustment member 21 is configured to be threadedly connected to the loading platform 1 and can move relative to the loading platform 1 along its axial direction during the rotation relative to the loading platform 1, the support seat 22 is arranged below the loading platform and can be magnetically matched with the pre-positioning magnetic member 23 to position the first end 2111 to the mounting hole 2221 of the support seat 22, and the first end 2111 is installed in the mounting hole 2221 in a manner that can move along the axial direction of the height adjustment member 21.

[0047] With such a configuration, the first end 2111 can be accurately positioned in the mounting hole 2221 of the support seat 22 through the magnetic adsorption of the pre-positioning magnetic member 23, thereby achieving precise docking of the height adjustment member 21 with the support seat 22 and improving the installation efficiency of the height adjustment member 21 on the support seat 22.

[0048] It should be noted that, in this embodiment, the support seat 22 is usually provided on a specific device, and the stage 1 can be installed on the corresponding device by connecting the height adjustment member 21 with the support seat 22, so that the corresponding device can complete the corresponding operation. The stage 1 is provided with a detection component for detecting a specific model of OLED module, which is used to perform Mura adjustment on the OLED module and usually includes: a circuit board, a connecting plug, a connecting wire, etc. The height adjustment member 21 is configured to be threadedly connected to the stage 1 and can move relative to the stage 1 along its axial direction during the rotation relative to the stage 1, and the first end 2111 is installed in the mounting hole 2221 in a manner that can move along the axial direction of the height adjustment member 21. Therefore, by adjusting the height adjustment member 21 to rotate relative to the stage 1, it can be moved along its own axial direction, thereby adjusting the horizontality of the surface of the stage 1.

[0049] It is understandable that during the inspection of OLED modules of different models, the corresponding stage 1 needs to be installed on the corresponding equipment so as to perform Mura adjustment through the inspection components attached to the stage 1 corresponding to the OLED module.

[0050] In this embodiment, the loading platform 1 is configured as a rectangular parallelepiped structure. Correspondingly, the number of the supporting structures 2 is set to four, and the four supporting structures 2 are respectively arranged near the four corners of the loading platform 1. This ensures that the loading platform 1 has a relatively stable effect when mounted on the equipment through the supporting structures 2.

[0051] Furthermore, the pre-positioning magnetic member 23 is specifically configured as a circular ring structure, which is designed to be arranged coaxially with the height adjustment member 21 so as to better guide and position the first end 2111 of the height adjustment member 21.

[0052] refer to Figure 4 As shown in , the support seat 22 is composed of a base 221 and a cylindrical mounting portion 222, wherein the cylindrical mounting portion 222 is firmly mounted on the base 221, ensuring the stability and load-bearing capacity of the structure. A mounting hole 2221 is provided at the center of the end face of the cylindrical mounting portion 222 for receiving the first end 2111 of the height adjustment member 21. Through the magnetic attraction between the pre-positioning magnetic member 23 and the support seat 22, the lower end face of the pre-positioning magnetic member 23 can be tightly fitted with the end face of the cylindrical mounting portion 222, thereby achieving precise alignment, so that the first end 2111 can smoothly and accurately enter the mounting hole 2221, simplifying the installation process and improving work efficiency.

[0053] Optionally, the mounting hole 2221 is designed as a bottomed hole structure located on the end surface of the cylindrical mounting portion 222. This design not only increases the depth of the hole but also improves the stability of the installation. An internal thread is provided on the inner side wall of the bottomed hole to cooperate with the external thread on the height adjustment member 21.

[0054] Specifically, the height adjustment member 21 has a side wall connected to the first end 2111, and the side wall is carefully processed with an external thread that matches the internal thread of the mounting hole 2221. When the first end 2111 of the height adjustment member 21 is guided to the mounting hole 2221 by the pre-positioning magnetic member 23, by rotating the height adjustment member 21, its external thread and the internal thread of the mounting hole 2221 are tightly engaged, thereby achieving a firm connection between the height adjustment member 21 and the support base 22, and during the tight engagement process, the height adjustment member 21 is moved along its axial direction. This design not only ensures the accuracy of installation and improves the structural stability and reliability of the entire adjustable carrier, but also enables the height adjustment member 21 to move along its axial direction to adjust the position of the worktable 1 relative to the support base 22 in the axial direction.

[0055] Furthermore, the support structure is cleverly equipped with a limit baffle 24, which is carefully placed below the loading platform 1 and sleeved on the height adjustment member 21. To ensure a stable connection between the limit baffle 24 and the height adjustment member 21, a fixed connection method such as threaded connection or welding is adopted to effectively prevent relative movement between the two.

[0056] It is worth mentioning that the orthographic projection of the limit baffle 24 on the lower surface of the loading platform 1 is carefully designed to be located on the inner side of the orthographic projection of the annular pre-positioning magnetic member 23 on the lower surface of the loading platform. This design not only ensures the compactness of the structure, but also avoids interference between the limit baffle 24 and the pre-positioning magnetic member 23. The addition of the limit baffle 24 brings additional stability to the adjustable carrier. When the adjustable carrier is not in use, the limit baffle 24 can effectively prevent the accidental separation of the height adjustment member 21 and the loading platform 1, thereby protecting the integrity of the adjustable carrier and extending its service life. At the same time, it also provides users with a more convenient and reliable use experience.

[0057] Furthermore, an elastic damping member 25 is innovatively introduced into the support structure 2. This element is cleverly placed above the loading platform 1 and between the loading platform 1 and the height adjustment member 21. Its design purpose is to apply a certain elastic force to the height adjustment member 21. Through the action of this elastic force, the limit baffle 24 can be tightly abutted against the lower surface of the loading platform 1, thereby ensuring that the height adjustment member 21 is always in an appropriate and stable position. When the height adjustment member 21 is rotated relative to the support seat 22 and installed in the mounting hole 2221, the presence of the elastic damping member 25 effectively prevents the height adjustment member 21 from deflecting, ensuring the accuracy and stability of the installation. Such a design not only improves the overall performance of the adjustable carrier, but also provides users with a more reliable and efficient use experience.

[0058] Optionally, the elastic damping member 25 is specifically implemented in the form of a spring, which is carefully mounted on the height adjustment member 21 to ensure that it can function stably. One end of the spring is designed to be in close contact with the loading platform 1, while the other end is in contact with the height adjustment member 21. This design enables the spring to transmit elastic force between the two. When the height adjustment member 21 is rotatably installed relative to the support seat 22, the presence of the spring can not only provide the necessary damping effect to prevent the height adjustment member 21 from deflecting, but also ensure that the limit baffle 24 always maintains abutment with the lower surface of the loading platform 1 through its elastic force. Such a structural design not only improves the stability and reliability of the adjustable carrier, but also makes the entire device smoother during operation, bringing a better user experience to the user.

[0059] Furthermore, the height adjustment member 21 is mainly composed of an adjustment screw 211 and a flange 212 formed on its side wall. The lower end of the adjustment screw 211 forms the first end of the height adjustment member, which is used to connect to the support seat 22 or other components. The flange 212 is cleverly arranged along the circumference of the side wall of the adjustment screw 211 and extends toward the upper end of the adjustment screw until it is flush with the upper end. This design allows one end of the spring to stably abut against the flange 212, while the other end is in close contact with the stage 1, thereby ensuring the effective transmission of the elastic force.

[0060] Furthermore, the interaction between the flange 212 and the stopper 24 forms a reliable anti-slip mechanism. This mechanism effectively prevents the adjustment screw 211 from accidentally detaching from the loading platform 1 during operation, thereby significantly improving the safety and stability of the adjustable carrier. This structural design not only demonstrates the practicality and innovation of this utility model, but also provides users with a more reliable and efficient user experience.

[0061] Preferably, the flange 212 is specially designed to be prismatic, which not only enhances structural strength but also provides a more convenient grip for the user. The user can easily grasp the side of the prismatic flange 212, thereby more effectively applying torque to the height adjustment member 21 to achieve precise height adjustment.

[0062] Furthermore, the stage 1 is provided with a carefully designed mounting hole 11, the inner wall of which is cleverly provided with an internal thread to mate with the external thread on the side wall of the height adjustment member 21. The height adjustment member 21 is stably inserted into the mounting hole 11 via the external thread on its side wall, achieving height adjustability.

[0063] Furthermore, to ensure the reliability of the anti-detachment structure, the projections of the flange 212 and the stopper 24 on the lower surface of the loading platform 1 are both located outside the projection of the mounting hole 11 on the lower surface of the loading platform 1. This design allows the flange 212 and the stopper 24 to effectively block the height adjustment member 21, preventing it from accidentally detaching from the loading platform 1 during adjustment or when not in use. This structure enhances the stability of the adjustable carrier.

[0064] In certain embodiments, reference Figure 5-6 As shown, the height adjustment member 21 further includes a second end 2112 located above the loading platform 1, and the second end 2112 is disposed opposite the first end 2111. To facilitate height adjustment by the user, a receiving groove 21121 is specially designed on the end surface of the second end 2112. The receiving groove can perfectly match the screwdriver head, thereby facilitating the user to apply torque for adjustment.

[0065] In summary, the embodiments of the present invention achieve the following technical effects:

[0066] 1) Through the magnetic attraction of the pre-positioning magnetic member 23, the first end 2111 can be accurately positioned in the mounting hole 2221 of the support base 22, thereby achieving precise docking of the height adjustment member 21 with the support base 22 and improving the installation efficiency of the height adjustment member 21 on the support base 22;

[0067] 2) The elastic damping member 25 can effectively prevent the height adjustment member 21 from deflecting;

[0068] 3) The flange 212 cooperates with the limiting baffle 24 to effectively prevent the height adjustment member 21 from separating from the loading platform 1 .
