DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1 and Figure 2 As shown, the present embodiment discloses a semi-automatic pull-out table with gear sliding, comprising a table frame, two table boards 1 and a gear sliding mechanism, wherein the two table boards 1 are symmetrically arranged front and back and connected to the table frame by reverse sliding through the gear sliding mechanism. The table frame comprises a table frame 2 and table legs 3 arranged at the bottom of the table frame 2, wherein the table frame 2 is composed of four frame tubes, namely, front, rear, left and right.

[0021] Specifically, the gear sliding mechanism is composed of a main sliding assembly and a driven sliding assembly.

[0022] The main sliding assembly includes: a long slide 4, which is composed of a plate body and a slide rail arranged on the narrow side above the plate body; the plate body is fixedly attached to the inner side of the left frame tube by bolts 5, and the slide rail is higher than the top surface of the table frame 2, and two groups of symmetrically arranged desktop connectors are slidably connected on the slide rail, and the two groups of desktop connectors are fixedly installed with two table boards 1 respectively. A rotating gear 6 is respectively arranged at the front and rear ends on the wide side of the plate body, and a transmission shaft 7 rotating with it is fixedly installed in the middle of the rotating gear 6, and a transmission gear chain 8 is meshed and connected to the outer side of the rotating gear 6, and the transmission gear chain 8 is divided into an upper transmission belt and a lower transmission belt that move in opposite directions. A main sliding connector 9 is respectively arranged in the two groups of desktop connectors, and the two main sliding connectors 9 are respectively fixedly connected to the upper transmission belt and the lower transmission belt, and a pluggable pin 10 can be arranged on the main sliding connector 9, and the front end of the pin 10 is embedded between the teeth of the transmission gear chain 8 or the two are connected in a buckle form. The main body of the desktop connector is located outside the transmission gear chain 8, and the height of the lower edge of the main body is lower than the height of the transmission shaft 7, and the upper part of the desktop connector is provided with a slide groove matching the slide rail. It can be understood that the transmission shaft 7 plays a role in limiting the sliding of the desktop connector on the long slide plate 4 to protect the table top 1 from sliding off the table frame.

[0023] The driven sliding assembly is installed on the right frame tube, and includes: a secondary slide 11 which has the same structure as the long slide 4 and is symmetrically arranged, a driven desktop connector 12 which is slidably connected to the secondary slide 11, and the driven desktop connector 12 is fixedly installed with its corresponding table top 1.

[0024] In some embodiments, a driven gear corresponding to the rotating gear 6 and a driven gear chain meshingly connected to the driven gear can also be configured in the driven sliding assembly, and the two ends of the transmission shaft 7 are respectively connected to the corresponding rotating gear 6 and the driven gear, playing the role of a driven connection. The same can also be adapted to the corresponding pin shaft 10. This configuration is more suitable for pushing when the desktop is heavy, and the overall table top 1 will move more smoothly and stably.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. In the present utility model, unless otherwise clearly specified and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0026] The above is only a preferred implementation case of the utility model, and does not limit the utility model in any form. Although the implementation process of the utility model is described in detail above, for those familiar with the art, they can still modify the technical solutions recorded in the above examples, or replace some of the technical features therein with equivalents.
