[0040] The present invention provides an integrated table and chair with automatic reset. To make the purpose, technical solutions and effects of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 7, the present invention provides an integrated table and chair with automatic reset function, including a seat board 12 with a backrest 11, a mounting seat 3 fixedly installed on the seat board 12 by means of bolts, a bracket 13, a table board 14 fixedly installed on the bracket 13 and located in front of the seat board 12, an automatic reset rotary shaft 2, a locking mechanism 4, a support rod 5, and an automatic return mechanism 6 installed on the bracket 13.

[0042] As Figure 5 shown, the mounting seat 3 is provided with a card slot 31 and a shaft hole 32 that communicates with the card slot 31 and is vertically axially. Specifically, the mounting seat 3 is the seat board chassis of an existing lift chair, installed below the seat board 12 to support the seat board, as Figure 7 shown. Of course, it can also be other types of seat board chassis with shaft holes and card slots.

[0043] As Figure 5 , Figure 7 shown, the top of the automatic reset rotary shaft 2 is inserted into the shaft hole 32 and is connected with the shaft hole 32 in a matching manner. The inner diameter of the shaft hole 32 is suitable for the outer diameter of the top of the automatic reset rotary shaft 2. When the automatic reset rotary shaft 2 is inserted into the shaft hole 32, the mounting seat 3 can only rotate along the automatic reset rotary shaft 2 without horizontal shaking.

[0044] As Figure 3 , Figure 4 , Figure 5 , Figure 6 shown, the locking mechanism 4 includes a connecting screw 41, a clamping part 43, and a connecting part 42; the clamping part 43 is respectively fixedly installed on both sides of the top end of the connecting part 42 and is clamped in the card slot 31; the bottom end of the connecting part 42 is provided with an inclined surface 47, the bottom of the connecting part 42 is inserted into the shaft hole 32, and the connecting end 21 of the top of the automatic reset rotary shaft 2 is in contact with the inclined surface 47 in a matching manner. That is, when the connecting screw 41 connects the connecting part 42 and the automatic reset rotary shaft 2, the inclined surface 47 is in close contact with the inclined surface 22 provided at the connecting end 21 of the top of the automatic reset rotary shaft 2. The connecting screw 41 passes through the connecting part 41 and is threadedly connected with the automatic reset rotary shaft 2.

[0045] The projection of the connecting part 41 on the horizontal plane is circular, and its diameter is smaller than the shaft hole 32, which is convenient for the connecting part 42 to be inserted into the shaft hole 32 and reduces the disassembly and assembly difficulty. In addition, a groove (not shown in the figure) is provided at the top of the automatic reset rotary shaft 2, and the connecting end 21 of the automatic reset rotary shaft 2 is located in the groove, and the connecting part 42 is correspondingly inserted into the groove to be connected with the connecting end 21, hiding the connection between the automatic reset rotary shaft 2 and the connecting part 42 in the groove.

[0046] Bevel surfaces 47 and 22 are respectively arranged at the connection positions of the connecting part 42 and the automatic reset swing shaft 2, which increases the contact area, thereby increasing the frictional force, being conducive to strengthening the connection between the connecting part 42 and the automatic reset swing shaft 2, preventing rotation and loosening between the connecting part 42 and the automatic reset swing shaft 2 so that the return-to-normal effect is reduced, and there is no need to perform troublesome hole alignment during installation. When the bevel surfaces 47 and 22 are in fit, the hole alignment is completed, facilitating the insertion of the connecting screw into the connecting part 42 and screwing it into the connecting end 21, reducing the installation difficulty.

[0047] The present invention adopts a locking mechanism 4 with a unique structure and an automatic reset swing shaft 2. Through the cooperation of the two, it realizes a fixed connection with the existing mounting seat 3. It not only has a good locking effect, is easy to manufacture and install, but also has good versatility, without the need to design a suitable mounting seat and corresponding manufacturing molds, greatly reducing the production cost of the enterprise.

[0048] As Figure 1 、 Figure 2 shown, the bottom of the automatic reset swing shaft 2 is fixedly arranged at one end of the support rod 5; the other end of the support rod 5 is connected to the automatic return-to-normal mechanism 6 so that the support rod 5 can automatically return to normal after rotation.

[0049] The present invention uses the locking mechanism 4 and the automatic reset swing shaft 2 to be fixedly connected to the mounting seat 3. The mounting seat 3 is installed at the bottom of the seat plate 12 through bolts. Then, the bottom of the automatic reset swing shaft 2 is fixed to one end of the support rod 5 by welding or bolt connection. The other end of the support rod 5 is connected to the automatic return-to-normal mechanism 6, and the automatic return-to-normal mechanism 6 is fixed to the bracket 13 by bolt installation. Thus, the support rod 5 can rotate significantly in the horizontal plane under the action of the automatic return-to-normal mechanism 6 to adjust the distance between the seat plate 12 and the tabletop 14, thereby improving the use comfort. And, the support rod 5 can automatically rotate and reset after rotation (after the human body leaves), without manual reset.

[0050] In addition, the seat plate 12 can rotate 360° under the action of the automatic reset swing shaft 2 and automatically return to normal after the human body leaves. Through the action of the automatic return-to-normal mechanism 6 and the automatic reset swing shaft 2, it is promoted that the seat plate 12 can rotate and can automatically return to its original position, thereby ensuring that the seat plate can be directly facing the podium in the classroom.

[0051] Of course, as Figure 2 、 Figure 8As shown, the support rod 5 is provided with a mounting hole 52. The bottom of the automatic reset rotary shaft 2 is inserted into the mounting hole 52 and fixed, so that the bottom of the automatic reset rotary shaft 2 can rotate synchronously with the rotation of the support rod 5. At the same time, when the top of the automatic reset rotary shaft 2 rotates as the seat plate 12 rotates, the bottom of the automatic reset rotary shaft 2 can remain stationary, so that the seat plate 12 can automatically reset under the action of the automatic reset rotary shaft 2.

[0052] As Figure 3 、 Figure 6 shown, specifically, the connecting portion 42 is provided with a vertically arranged through hole 44, the connecting screw 41 is inserted through the through hole 44, and the top of the automatic reset rotary shaft 2 is provided with a connecting screw hole (not shown in the figure) connected to the connecting screw 41.

[0053] As Figure 4 shown, specifically, the connecting screw 41 is an internal hexagonal screw. An internal hexagonal wrench is used to turn the connecting screw, which is labor-saving and convenient, and speeds up the installation speed. Of course, it can also be other types of screws, such as external hexagonal screws.

[0054] As Figure 4 shown, the clamping portion 43 is provided with a limit screw 45 arranged vertically and fixedly connected thereto, and the limit screw 45 is clamped in the clamping groove 31.

[0055] As Figure 3 、 Figure 4 、 Figure 5 shown, after inserting the top of the automatic reset rotary shaft 2 into the shaft hole 32, insert the connecting portion 42 into the shaft hole 32 and place the clamping portion 43 in the clamping groove 31, and use the connecting screw 41 to realize the connection between the automatic reset rotary shaft 2 and the connecting portion 42; then use the limit screw 45, screw it into the connecting hole 46 provided in the clamping portion 43, and the edge of the limit screw 45 contacts the inner wall surface of the clamping groove 31, realizing that the clamping portion 43 is clamped in the clamping groove 31, thereby ensuring that the mounting seat 3 can drive the locking mechanism 4 to rotate simultaneously. Moreover, since a strong locking effect is established between the locking mechanism 4 and the top of the automatic reset rotary shaft 2, the top of the automatic reset rotary shaft 2 is promoted to rotate synchronously with the mounting seat 3. After the person leaves, it will automatically rotate in the reverse direction and reset.

[0056] As Figure 2 、 Figure 8 、 Figure 9 、 Figure 11 shown, specifically, the automatic return mechanism 6 includes a fixed seat 61 fixedly arranged on the bracket 13 by means of bolt installation, a fixed shaft 63 arranged vertically and fixed at both ends on the fixed seat 61, a torsion spring 64 sleeved on the fixed shaft 63, a fixed block 65 fixed on the fixed shaft 63, a rotating block 62 and a support block 66 both rotatably arranged on the fixed shaft 63.

[0057] Among them, the upper end of the torsion spring 64 is fixedly arranged at the bottom of the rotating block 62, and the lower end of the torsion spring 64 is fixedly arranged at the top of the fixed block 65. The support block 66 is arranged below the fixed block 65. The support rod 5 is provided with a rotating hole 51. The bottom of the rotating block 62 is clamped in the rotating hole 51. The top of the support block 66 penetrates through the rotating hole 51, and the fixed block 65 is located in the rotating hole 51.

[0058] When the support rod 5 rotates in the horizontal plane, it can drive the rotating block 62 to rotate simultaneously. The torsion spring 64 deforms due to the rotation of the rotating block 62 and the stable immobility of the fixed block 65, thereby driving the support rod 5 to rotate in the reverse direction (return to its original shape) due to the action of the torsion spring 64 after rotation and the departure of the human body, and return to its original position.

[0059] Such as Figure 11 、 Figure 12 、 Figure 13 As shown, the rotating block 62 is provided with an insertion hole 622 suitable for the upper end of the torsion spring 64 to be inserted and achieve fixed connection, and the fixed block 65 is provided with an insertion hole 651 suitable for the lower end of the torsion spring 64 to be inserted and achieve fixed connection, so as to fixedly connect the two ends of the torsion spring with the rotating block 62 and the fixed block 65 respectively, and the disassembly and assembly are very simple.

[0060] Such as Figure 8 、 Figure 10 As shown, specifically, the fixed seat 61 is provided with a limiting groove 611 for limiting the horizontal swing angle of the support rod 5, and the support rod 5 is fixedly provided with a limiting block 53 located in the limiting groove 611. In this embodiment, the limiting block 53 and the support rod 5 are integrally formed. When the rotation reaches the position, the limiting block 53 contacts one side wall surface of the limiting groove 611; when the support rod 5 returns to its original position, the limiting block 53 contacts the other side wall surface of the limiting groove 611.

[0061] In addition, the fixed seat 61 is provided with mounting holes 612 suitable for the upper and lower ends of the fixed shaft 63 to be inserted. Then, screws are used for locking. The horizontally arranged screws are screwed into the vertically arranged fixed shaft 63 from the fixed seat 61, so that the fixed shaft 63 is firmly fixed in the fixed seat 61 and will not rotate. Subsequently, an end cover 613 is used to cover the mounting hole, which plays a role in protecting the fixed shaft from the influence of water vapor and is beautiful and durable.

[0062] Such as Figure 8 、 Figure 11 、 Figure 12 As shown, specifically, the bottom of the rotating block 62 is provided with a clamping block 621 integrally formed with its outer peripheral surface, and the support rod 5 is correspondingly provided with a clamping opening 54 in the rotating hole 51; the clamping block 621 is clamped in the clamping opening 54.

[0063] Both the rotating block 62 and the supporting block 66 are bosses with a circular cross-section. The diameters of the bottom of the rotating block 62 and the top of the supporting block 66 are suitable for the inner diameter of the rotating hole 51 provided on the support rod 5. Through the cooperation connection of the bayonet 54 and the clamping block 621, the rotating block 62 is clamped to the support rod 5, so as to realize the synchronous rotation of the rotating block 62 and the support rod 5. The bottom surface of the supporting block 66 is in contact with the fixed seat 61, strongly supporting the support rod 5, while the support rod 5 rotates relative to the supporting block 66.

[0064] As Figure 8 , Figure 9 , Figure 11 shown, specifically, bearings are respectively provided at the upper and lower ends of the fixed shaft 63; the bearings are rotatably arranged on the fixed shaft 63. An installation groove (not marked in the figure) is provided at the top of the rotating block 62, and the bearing 67 is installed in the installation groove provided on the rotating block 62. Similarly, an installation groove is provided at the bottom of the supporting block 66, and the bearing is installed in the installation groove.

[0065] The setting of the bearings is to reduce the frictional resistance between the supporting block 66, the rotating block 62 and the fixed seat 61, so as to make the rotation of the support rod 5 smoother. The outer end surface of the bearing is in contact with the fixed seat 61, and the inner diameter of the bearing is suitable for the diameter of the fixed shaft 63, to prevent the top surface of the rotating block 62 and the bottom surface of the supporting block 66 from contacting the fixed seat 61 and generating frictional force.

[0066] As Figure 11 , Figure 13 shown, specifically, the fixing block 65 is vertically provided with a clamping hole 653, and the fixed shaft 63 is correspondingly provided with a clamping portion 631 that is clamped in the clamping hole 653. In this embodiment, the fixing block 65 is provided with a clamping portion 652 in the circular through hole to form the clamping hole 653. When the fixed shaft 63 is inserted into the clamping hole 653 from top to bottom, the clamping portion 631 is in contact with the inner wall surface of the clamping hole 653, and the clamping portion 652 can support the fixed shaft 63 to prevent the fixed shaft 63 from moving down further.

[0067] As Figure 1 shown, two of the automatic return mechanisms 6 and the seat plates 12 are respectively provided and are respectively symmetrically arranged on the left and right sides of the bracket 13. In this embodiment, the integrated desk and chair provides two seats. The two seat plates 12 share one bracket 13 and one table board 14, and has the advantages of automatic return, saving manufacturing materials and teaching site space, being stable and reliable, beautiful and durable, and is very suitable for use in schools.

[0068] In summary, the present invention provides an integrated desk and chair with automatic reset function, which has a novel and unique structure, is easy to disassemble and assemble, has a low cost, can provide a strong locking effect, realizes the automatic straightening function, and has a good straightening effect. The present invention can be applied in the classroom to ensure that the seat board can automatically return to its original position after rotation, thereby ensuring that the seat board is directly facing the podium in the classroom to maintain neatness.

[0069] The present invention effectively utilizes the seat board chassis of the existing lift chair, and on this basis, designs a locking mechanism and an automatic reset rotary shaft with characteristics such as strong locking effect and easy installation, which are used to connect the seat board chassis and the support rod. It has good versatility and there is no need to design a suitable seat board chassis and the mold for manufacturing the seat board chassis, greatly reducing the operating cost of the production enterprise.

[0070] In addition, the present invention also provides an automatic straightening mechanism, which enables the support rod to rotate, so as to adjust the distance between the seat board and the table board, improve the comfort of the user, and through the automatic straightening mechanism, the support rod can automatically return to its original position after horizontal rotation to maintain neatness without manual straightening.

[0071] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solutions and inventive concepts of the present invention, and all such changes or substitutions should fall within the protection scope of the appended claims of the present invention.
