Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to an experimental table with a bidirectional synchronous extension structure. Background Art

[0002] As the core facility of the laboratory, the laboratory bench plays a vital role. It is the basic platform for scientific researchers to carry out experimental operations. The laboratory bench is mainly composed of several parts: the stable cabinet body is the supporting skeleton of the entire laboratory bench, ensuring stability and safety during the experiment; the table top is the direct area for experimental operations, and corrosion-resistant and easy-to-clean materials are usually selected to meet the needs of different experiments; in addition, the laboratory bench is also equipped with auxiliary facilities such as sinks and faucets to facilitate cleaning and drainage operations. These components together constitute a fully functional and easy-to-operate laboratory bench, providing strong support for scientific research experiments.

[0003] At present, traditional laboratory benches mostly adopt an integrated molding design to enhance their overall stability. However, this design also limits the size of the laboratory bench surface, making it impossible to expand according to actual needs. The fixed table size leads to limited placement space on the laboratory bench, making it difficult to accommodate more experimental tools or supplies. When these tools or supplies are placed on the ground, they not only take up valuable space in the laboratory, but may also be accidentally kicked or bumped by the experimenter's walking, which not only affects the experimental efficiency but also poses a threat to the experimenter's safety. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a test bench with a bidirectional synchronous extension structure to solve the technical problems raised in the above background technology.

[0006] Extension grooves are provided inside both sides of the table top, and extension plates are movably connected inside the extension grooves. An extension mechanism is provided between the extension plates and the extension grooves, and the extension mechanism includes an electric push rod, a rack, a gear, a support column, a rotating plate and a connecting plate. The rotating plate is movably connected inside the extension grooves, and the connecting plate is movably connected between the rotating plate and the extension plate.

[0007] Preferably, the interior of the extension groove is symmetrically provided with limiting rods, and the interior of the extension plate is symmetrically provided with limiting holes.

[0008] Preferably, the limiting rod is set to a "T"-shaped structure, and the extension plate and the extension groove form a sliding structure through the limiting hole and the limiting rod. The limiting holes and the limiting rod are both symmetrically arranged in two groups about the central axis of the table.

[0009] Preferably, a support column rotatably connected to the extension groove via a bearing is provided at the bottom end of the rotating plate, and a gear is sleeved on the outer surface of the support column.

[0010] Preferably, a rack is meshedly connected to one side of the gear, and a rack is installed between the rack and the vertical plate on the inner side of the extension groove.

[0011] Preferably, a rotating structure is formed between the connecting plate, the rotating plate and the extension plate through a pin shaft, and two connecting plates and two rotating plates are symmetrically arranged about the central axis of the table top.

[0012] Preferably, a limiting groove is provided on the inner side of the extension groove, and a limiting block is symmetrically provided at the bottom end of the rack to form a sliding structure with the limiting groove.

[0013] In summary, the present invention has the following beneficial effects:

[0014] The utility model is provided with an extension plate and an extension mechanism. Since the gear is meshed with the rack, when the electric push rod works and extends, the rack slides horizontally and drives the gear, support column and rotating plate to rotate. Since the connecting plate, the extension plate and the rotating plate are all rotatably connected by a pin shaft, and the extension plate and the extension groove are slidably connected by a limit rod and a limit hole, the extension plate extends outward under the action of the connecting plate and the rotating plate, thereby realizing the extension operation of the laboratory table top, so as to place more required experimental tools or supplies, ensuring the efficiency and safety of the experiment, and when the electric push rod works synchronously, the two-way synchronous extension operation of the laboratory table top can be realized, which is more flexible and convenient to use.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] The following describes an embodiment of the present invention based on its overall structure.

[0022] A test bench with a bidirectional synchronous extension structure, such as Figure 1 and Figure 2 As shown, it includes a countertop 1, a cabinet 2, a sink 3 and a faucet 4. The faucet 4 is installed on the top of the countertop 1, and the sink 3 is installed at the front end of the faucet 4 on the top of the countertop 1. The cabinet 2 is provided at the bottom of the countertop 1;

[0023] See Figures 1-4 It can be seen that the interior of both sides of the table 1 is provided with an extension groove 5, the interior of the extension groove 5 is movably connected with an extension plate 6, an extension mechanism 7 is provided between the extension plate 6 and the extension groove 5, the extension mechanism 7 includes an electric push rod 701, a rack 702, a gear 703, a support column 704, a rotating plate 705 and a connecting plate 706, the rotating plate 705 is movably connected to the interior of the extension groove 5, the connecting plate 706 is movably connected between the rotating plate 705 and the extension plate 6, the rotating plate The bottom end of 705 is provided with a support column 704 rotatably connected to the extension groove 5 via a bearing. The outer surface of the support column 704 is sleeved with a gear 703. One side of the gear 703 is meshed with a rack 702. The rack 702 is installed between the rack 702 and the vertical plate inside the extension groove 5. The connecting plate 706, the rotating plate 705, and the extension plate 6 form a rotating structure through a pin shaft. The connecting plate 706 and the rotating plate 705 are both symmetrically provided with two about the central axis of the table top 1.

[0024] See Figures 1-4It can be seen that due to the meshing connection between the gear 703 and the rack 702, during the operation and extension of the electric push rod 701, the rack 702 slides horizontally and drives the gear 703, the support column 704 and the rotating plate 705 to rotate. Since the connecting plate 706 and the extension plate 6 and the rotating plate 705 are all rotatably connected by the pin shaft, and the extension plate 6 and the extension groove 5 are slidably connected by the limit rod 9 and the limit hole 8, the extension plate 6 extends outward under the action of the connecting plate 706 and the rotating plate 705, thereby realizing the extension operation of the laboratory table top 1, so as to place more required experimental tools or supplies, ensuring the experimental efficiency and safety, and when the electric push rod 701 works synchronously, the two-way synchronous extension operation of the laboratory table top 1 can be realized, which is more flexible and convenient to use.

[0025] See Figure 2 and Figure 4 It can be seen that the limit rods 9 are symmetrically arranged inside the extension groove 5, and the limit holes 8 are symmetrically opened inside the extension plate 6. The limit rods 9 are arranged in a "T"-shaped structure. The extension plate 6 and the extension groove 5 form a sliding structure through the limit holes 8 and the limit rods 9. There are two groups of limit holes 8 and limit rods 9 symmetrically arranged about the central axis of the table top 1, which can guide the extension plate 6, so as to prevent the extension plate 6 from tilting during the sliding process, so as to stabilize the sliding process of the extension plate 6.

[0026] See Figure 3 and Figure 4 It can be seen that a limiting groove 11 is opened on the inner side of the extension groove 5, and a limiting block 10 is symmetrically arranged at the bottom end of the rack 702 to form a sliding structure with the limiting groove 11, which can play a role in supporting and limiting the rack 702, thereby increasing the stability of the rack 702 during the sliding process and preventing displacement.

[0027] The working principle of the present invention is as follows: when using the experimental table with a bidirectional synchronous extension structure, the electric push rod 701 is operated and extended. During this process, the rack 702 slides horizontally and drives the gear 703, the support column 704 and the rotating plate 705 to rotate, and then the extension plate 6 is extended outward under the action of the connecting plate 706 and the rotating plate 705, so that the extension operation of the experimental table top 1 can be realized to place more required experimental tools or supplies, and when the electric push rod 701 works synchronously, the bidirectional synchronous extension operation of the experimental table top 1 can be realized, which is more flexible and convenient to use.
