Description

Technical Field

[0001] The present invention relates to the technical field of furniture, and specifically refers to an adjustable bamboo and wooden dining table, which can conveniently adjust the tabletop of bamboo and wooden products to improve the adaptability of the products in use. Background Art

[0002] A dining table refers to a table specifically for eating, and can be divided into bamboo and wooden dining tables, marble dining tables, etc. according to the material. A bamboo and wooden dining table, as the name implies, is a dining table always made of bamboo and wood materials. To improve the adaptability of bamboo and wooden dining tables in use, many manufacturers have begun to devote themselves to the research and design of bamboo and wooden dining tables with adjustable tabletop usage areas.

[0003] At present, there are many types of adjustable bamboo and wooden dining tables commonly found on the market. Among them, the simplest structure is to directly set a group of movable table panels on the basis of a support mechanism, and then an adjustable table panel is detachably installed between the group of movable table panels. When it is necessary to expand the usage area of the dining table, the group of movable table panels can be moved outwards respectively, and then the adjustable table panel is fixedly installed between the group of movable table panels. To ensure the splicing stability between the movable table panels or after adding the adjustable table panel, corresponding locking mechanisms need to be fixedly installed on the bottom sides of the existing group of movable table panels and the adjustable table panel respectively. It not only has a relatively complex structure, but also requires personnel to lie under the tabletop for operation during the operation process, which is very troublesome and does not meet the requirements of modern furniture use.

[0004] Therefore, the research purpose of the present invention is to design an adjustable bamboo and wooden dining table with a simple structure and significantly improved convenience in tabletop adjustment operation. Summary of the Invention

[0009] The desktop mechanism includes a set of movable table panels movably installed on both sides of the fixed frame, and an adjustable table panel detachably installed between the set of movable table panels. Sliders adapted to the guide rails are fixedly connected to the bottoms of the movable table panels respectively, and the movable table panels are movably installed on the fixed frame through the cooperation of the sliders and the guide rails. After the set of movable table panels move away from each other, the adjustable table panel is fixedly installed between the set of movable table panels.

[0010] The desktop limiting mechanism includes at least one limiting cross beam fixedly connected to the middle of the fixed frame. A set of corresponding limiting rods are swingably installed in the middle of the limiting cross beam. Corresponding card slots are recessed on the upper end faces of the limiting rods respectively. A corresponding support shaft is telescopically installed downward through a small stiffness spring at the bottom side of each of the set of movable table panels. Support rollers rotatably installed at the bottom sides of the support shafts are respectively clamped into the card slots of the limiting rods. Big stiffness springs for pushing the limiting rods upward are fixedly connected to the limiting cross beam respectively.

[0011] The driving mechanism includes electromagnets fixedly connected to the inner sides of the big stiffness springs. Magnetic metal blocks adapted to the electromagnets are fixedly connected to the limiting rods respectively. When the electromagnets are not energized, the big stiffness springs push the limiting rods upward, the support rollers roll inward, the small stiffness springs are compressed, and the set of movable table panels move inward to be spliced into the first desktop. When the electromagnets are energized, the magnetic metal blocks are adsorbed, driving the limiting rods to swing downward, the big stiffness springs are compressed, and the small stiffness springs drive the support rollers to roll outward under the action of elastic force, so as to drive the set of movable table panels to move outward in place and fixedly install the adjustable table panel between the set of movable table panels to be spliced into the second desktop.

[0012] The feet, fixed frame, limiting cross beam, movable table panels, and adjustable table panel are all made of bamboo and wood materials.

[0015] The card slots on the limiting rods are inverted T-shaped slots. The bottom ends of the support shafts extend into the inverted T-shaped slots, and the support rollers are respectively rotatably installed at the bottom ends of the support shafts and abut against both sides of the inverted T-shaped slots.

[0016] A group of the movable desktop panels are fixedly connected with corresponding guide sleeves at positions corresponding to the small stiffness springs on the bottom sides thereof, the support shafts are respectively telescopically inserted into the guide sleeves, and the small stiffness springs are respectively fixedly connected between the support shafts and the guide sleeves.

[0017] The guide rails are respectively fixed with limiting plates for limiting the sliding blocks.

[0018] The supporting feet are arranged to tilt outwards respectively, and corresponding pulling rods are fixedly connected between two adjacent supporting feet.

[0019] The pulling rod is made of bamboo or wood material.

On this basis, the present invention is further provided with a driving mechanism, which includes an electromagnet fixedly connected to the inner side of the large stiffness spring, and the limiting rods are respectively provided with magnetic metal blocks that match the electromagnets.

[0022] When the electromagnet is not energized, the large-rigidity spring pushes the limit rod upward, causing the support roller to roll inward. At this time, the small-rigidity spring is compressed, and a group of movable desktop panels move inward to form a first desktop. During the use of the first desktop, the outer end of the limit rod is in an upward swing state under the pushing action of the large-rigidity spring, thereby limiting the support roller, that is, limiting a group of movable desktop panels, thereby effectively maintaining the stability of the first desktop.

[0023] When the electromagnet is powered on, the magnetic metal block is attracted, thereby driving the limit rod to swing downward, compressing the large stiffness spring. At this time, the support roller can be driven to roll outward under the elastic force of the small stiffness spring, so as to drive a group of movable desktop panels to move outward into position, and then the adjustable desktop panel is fixedly embedded between the group of movable desktop panels to form a second desktop; thereafter, the electromagnet is powered off to maintain the stability of the second desktop. Therefore, the present invention is not only simple in structure, but also can significantly improve the convenience of desktop adjustment operation, and can effectively ensure the stability of the first desktop and the second desktop after being spliced into position.

[0024] 2) Between a set of movable table panels of the present invention, a first fixing groove is recessed at the inner end of one movable table panel, and a first convex edge adapted to the first fixing groove is provided at the inner end of the other movable table panel.

[0032] The desktop mechanism 2 includes a set of movable table panels 201 movably installed on both sides of the fixed frame 102, and an adjustable table panel 202 detachably installed between the set of movable table panels 201. Sliders 203 adapted to the guide rails 103 are fixedly connected to the bottoms of the movable table panels 201 respectively. The movable table panels 201 are movably installed on the fixed frame 102 through the cooperation of the sliders 203 and the guide rails 103. After the set of movable table panels 201 move away from each other, the adjustable table panel 202 is fixedly installed between the set of movable table panels 201.

[0033] The desktop limiting mechanism 3 includes at least one limiting cross beam 301 fixedly connected to the middle of the fixed frame 102. A set of corresponding limiting rods 302 are swingably installed in the middle of the limiting cross beam 301. Corresponding card slots 4 are respectively recessed on the upper end surfaces of the limiting rods 302. A corresponding support shaft 6 is telescopically installed downward through a small stiffness spring 5 on the bottom sides of the set of movable table panels 201 respectively. Support rollers 7 that are rotatably installed at the bottom sides of the support shafts 6 and are snapped into the card slots 4 of the limiting rods 302 are provided.

[0034] The driving mechanism 9 includes an electromagnet 901 fixedly connected to the inner side of the big stiffness spring 8. Magnetic metal blocks 902 adapted to the electromagnet 901 are fixedly connected to the limiting rods 302 respectively. When the electromagnet 901 is not energized, the big stiffness spring 8 pushes up the limiting rods 302, the support rollers 7 roll inward, the small stiffness spring 5 is compressed, and the set of movable table panels 201 move inward to be spliced into a first desktop. When the electromagnet 901 is energized, the magnetic metal blocks 902 are adsorbed, driving the limiting rods 302 to swing downward, the big stiffness spring 8 is compressed, and the small stiffness spring 5 drives the support rollers 7 to roll outward under the action of elastic force, so as to drive the set of movable table panels 201 to move outward in place, and then fixedly install the adjustable table panel 202 between the set of movable table panels 201 to be spliced into a second desktop.

At this time, the small-rigidity spring 5 is compressed, and a group of movable table boards 201 move inward and are spliced into the first tabletop. During the use of the first tabletop, the outer end of the limit rod 302 is in an upward swing state under the pushing action of the large-rigidity spring 8, thereby forming a limit on the support roller 7, that is, forming a limit on a group of movable table boards 201, so as to effectively maintain the use stability of the first tabletop.

[0037] When the electromagnet 901 is energized, the magnetic adsorption metal block 902 is adsorbed, thereby driving the limit rod 302 to swing downward, compressing the large-rigidity spring 8.
