Description

Technical Field

[0001] The utility model relates to an office equipment, in particular to an office lifting table which can be lifted, folded and carried. Background Art

[0002] Most of the current desks cannot be adjusted in height. Only a small part can be adjusted in height, but the adjustable height of such desks is relatively limited. Moreover, the desktop is lifted as a whole, which is not very convenient to adjust when there are many and heavy items placed on it. As we know, when people work for a long time, they often need to lift the desktop to adjust their sitting posture and eye use angle, etc. And the position we usually need to lift is just the local position of the computer and the place to put hands on the table. For this reason, someone has developed a lifting platform placed on the office desk, such as the adjustable support slow-down lifting table with the patent publication number CN 215382129 U. In actual use, we found that its structure is relatively complex (springs need to be set on both sides of the gas spring respectively), and the operation is relatively laborious (because the handle and the buckle are close to the gas spring, and the gas spring is unlocked by acting on the linkage plate and the brake plate that slide linearly). Summary of the Invention

[0003] The purpose of the utility model is to provide a desk lifting platform with a more reasonable structure, safer and more reliable use, which is labor-saving and can stop lifting at any time during operation.

[0004] In order to solve the above-mentioned existing technical problems, the utility model adopts the following technical solutions:

[0009] The lifting operation structure includes a gas spring, a gas spring unlocking control, an unlocking control return spring 43, a handle and a steel wire rope; after the gas spring is installed and fixed on the panel, its outer shell is connected to the synchronous push rod through a moving plate to form a sliding body, and the telescopic arm is installed and fixed on the panel through an arm box; the gas spring unlocking control is swingably connected to the panel and is connected to one end of the unlocking control return spring and the steel wire rope; the other end of the unlocking control return spring is installed on the panel; the other end of the steel wire rope is connected to the handle; the handle is installed on one side of the panel; when the gas spring unlocking control is in the reset state under the action of the unlocking control return spring, the gas spring is in the locked state; when the handle is operated to make the gas spring unlocking control swing against the acting force of the unlocking control return spring, the gas spring unlocking control acts on the trigger switch of the gas spring to enable the gas spring to expand and contract.

[0010] In the improvement scheme of the above-mentioned desk lifting platform, a horn-shaped bayonet is provided on the gas spring unlocking control; a perforation is provided on the arm box at a position facing the bayonet; a bolt is provided on the underframe; a clamping groove that can be inserted through the perforation and clamped on the bayonet is provided on the bolt.

[0011] In the improvement scheme of the above-mentioned desk lifting platform, a tapered head is provided at the insertion end of the bolt.

[0012] In the improvement scheme of the above-mentioned desk lifting platform, an auxiliary opening structure is further included, which includes a torsion spring provided on the panel and a cross column provided on the bracket; when the panel is in the folded state, the cross column presses on the extension arm of the torsion spring.

[0013] In the improvement scheme of the above-mentioned desk lifting platform, a torsion spring cover that can cover the torsion spring is provided on the panel; a cross column avoidance groove is provided on the torsion spring cover.

[0014] In the improvement scheme of the above-mentioned desk lifting platform, the gas spring unlocking control is fan-shaped. After its center end is swingably connected to the panel, the left side is connected to the steel wire rope and the right side is connected to the unlocking control return spring; the bayonet is provided in the pipe hole at the front of the gas spring unlocking control.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: Since the lifting operation structure includes a gas spring, a gas spring unlocking control, an unlocking control return spring, a handle and a steel wire rope, and the gas spring realizes the unlocking of telescoping through the gas spring unlocking control that is swing-connected to the panel, and the gas spring unlocking control is swung by the handle far from the gas spring pulling the steel wire rope, in this way, the lifting operation structure is simplified and it is more labor-saving during operation; moreover, once the handle is released, after the gas spring unlocking control quickly resets under the unlocking control return spring, the gas spring cannot continue to telescope, so that the lifting of the panel can be stopped at any time to avoid the danger of hurting people. Therefore, the structure of the present utility model is more reasonable, safer and more reliable in use, and it is both labor-saving and can stop lifting at any time during operation.

[0022] Figure 6 is Figure 5 an enlarged view of a partial I. Specific Embodiments

[0023] A desk lifting platform, as Figures 1 to 5 shown, includes a panel 1, a chassis 2, a bracket 3 and a lifting operation structure 4, wherein:

[0024] On both sides of the lower surface of the panel 1, upper slide rails 11 are provided;

[0025] The chassis 2 is square, and it can have one side open (as shown in this embodiment) or four sides closed; on two sides of one side of the chassis 2, lower slide rails 21 are provided, and they are on the same side of the panel 1 as the upper slide rails 11;

[0026] The bracket 3 is in an X shape and there are two pairs; the upper and lower ends on one side of the two pairs of brackets 3 are respectively hinged to the lower surface of the panel 1 and the chassis, and the upper ends on the other side are slidably connected to the upper slide rail 11 and then connected into one body by a synchronous push rod 5, and the lower ends are slidably connected to the lower slide rail 21 and then connected into one body by a synchronous slide rod 6;

[0027] The lifting operation structure 4 includes a gas spring 41, a gas spring unlocking control 42, an unlocking control return spring 43, a handle 44 and a steel wire rope 45; after the gas spring 41 is installed and fixed to the panel 1, its outer shell 411 is connected to the synchronous push rod 5 through a moving plate 46 to form a sliding body, and the telescopic arm 412 is installed and fixed to the panel 1 through an arm box 47; the gas spring unlocking control 42 is swingably connected to the panel 1 and connected to one end of the unlocking control return spring 43 and the steel wire rope 45; the other end of the unlocking control return spring 43 is installed on the panel 1; the other end of the steel wire rope 45 is connected to the handle 44; the handle 44 is installed on one side of the panel 1; when the gas spring unlocking control 42 is in a reset state under the action of the unlocking control return spring 43, the gas spring 41 is in a locked state; when the handle 44 is operated to make the gas spring unlocking control 42 swing against the acting force of the unlocking control return spring 43, the gas spring unlocking control 42 acts on the trigger switch 413 of the gas spring 41 to enable the gas spring to expand and contract.

[0028] When the present utility model wants to open the desk lifting platform in a folded state, the handle 44 is operated to pull the steel wire rope 45, so that the gas spring unlocking control 42 swings and acts on the trigger switch 413 of the gas spring 41. At this time, the X-shaped bracket 3 swings and narrows under the action of the gas spring 41, so that the panel 1 can be slowly lifted. During the lifting process, the handle 44 can be released at any time to immediately stop the lifting of the panel; when the open desk lifting platform needs to be folded, while pressing both hands on the panel 1, one of the hands should be able to act on the handle 44 to operate the handle 44 to pull the steel wire rope 45, so that the gas spring unlocking control 42 swings and acts on the trigger switch 413 of the gas spring 41, so that the panel can be pressed down for folding. Similarly, during the folding process, the handle can be released at any time to immediately stop the folding of the panel, so as to achieve the purpose of steplessly adjusting the height of the panel.

[0029] As can be seen from the above, since the gas spring 41 is unlocked for telescoping through the gas spring unlocking control 42 swing-connected to the panel 1, and the gas spring unlocking control 42 is swung by the handle 44 far from the gas spring 41 pulling the wire rope 45, in this way, the lifting operation structure 4 is simplified and the operation is more labor-saving; moreover, once the handle 44 is released, after the gas spring unlocking control 42 quickly resets under the action of the unlocking control return spring 43, the gas spring 41 cannot continue to telescope, so that the lifting of the panel 1 can be stopped at any time to avoid the danger of hurting people. Therefore, the structure of the present utility model is more reasonable, safer and more reliable in use, and it is labor-saving in operation and can stop lifting at any time.

[0030] In order to enable the lifting platform to maintain the best folded state to save storage space, in this embodiment, as Figure 2 、 4 、as shown in 5, a trumpet-shaped bayonet 421 is provided on the gas spring unlocking control 42; a through hole 471 is provided on the arm box 47 at a position facing the bayonet 421; a bolt 22 is provided on the chassis 2; a clamping groove 221 that can be inserted into the through hole 471 and clamped on the bayonet 421 is provided on the bolt 22. When the bayonet 421 of the gas spring unlocking control 42 is clamped in the clamping groove 221 of the bolt 22, it can prevent the panel from rebounding a little under the inertial action of the gas spring 41, so that the lifting platform can maintain the best folded state to achieve the purpose of saving the most storage space; preferably, a tapered head 222 is provided at the insertion end of the bolt 22 to facilitate the smooth clamping of the bayonet on the clamping groove after the gas spring unlocking control is swung.

[0031] Since the lifting platform starts to open from the fully folded state (as Figure 3 、 4 shown), the thrust of the gas spring 41 is relatively small at this moment. For this reason, in this embodiment as a preferred implementation, as Figure 2 、 4 、as shown in 5, it further includes an auxiliary opening structure 7, which includes a torsion spring 71 provided on the panel 1 and a cross column 72 provided on the bracket 3; when the panel 1 is in the folded state (as Figure 4 shown), the cross column 72 presses on the extension arm 711 of the torsion spring 71. In this way, at the moment when the panel is opened, the extension arm 711 of the torsion spring 71 reacts on the cross column 72, enabling the bracket 3 to have enough force to open slightly to assist in opening the panel a little; then, under the action of the gas spring 41, it can continue to open. Preferably, a torsion spring cover 12 that can cover the torsion spring 71 is provided on the panel 1 to improve the safety of use. A cross column avoidance groove 121 is provided on the torsion spring cover 12.

[0032] In this embodiment, as Figure 6As shown, the gas spring unlocking control 42 is fan-shaped. After its center end is swing-connected to the panel, the left side is connected to the steel wire rope 45, and the right side is connected to the unlocking control return spring 43. The bayonet 421 is arranged in the pipe hole 422 at the front of the gas spring unlocking control 42. The trigger switch 413 of the gas spring 41 contacts the vertical surface 423 of the gas spring unlocking control 42.
