Description

Technical Field

[0001] The utility model relates to the technical field of tables, in particular to a self-locking folding table. Background Art

[0002] At present, there are many types of folding tables on the market. Generally, the tabletop is supported by supporting legs after being folded in half. However, the supporting force is not strong and the stability is poor. In the Chinese patent document with the patent publication number "CN202722982U", an iron plate folding table is disclosed. The leg tube and the U-shaped support tube are rotated to be close to the bottom of the tabletop by setting a rotating leg cross tube, and the front end of the U-shaped support tube is fixed to the supporting middle cross tube with a nut; when unfolded, the leg tube is self-standing on the bottom surface, and the U-shaped support tube, the leg tube and the tabletop form a triangular support state, which plays a stabilizing role. However, in this way, when folding or unfolding the supporting legs, the nuts need to be twisted out, and the rotation angle of the leg tube when unfolding or folding needs to be manually controlled. After the operation, the nuts are aligned with the corresponding position to fix the U-shaped support tube on the supporting middle cross tube. The operation is complicated and not conducive to the use of the folding table. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a self-locking folding table, which can facilitate the unfolding or folding of the table legs through the setting of a limiting component to reduce the volume of the table. It can also self-lock and limit the position of the table legs after unfolding or folding, thereby ensuring the stability of the folding table when folded or unfolded, and is easy to operate.

[0004] In order to solve the above-mentioned technical problems, the utility model provides a self-locking folding table, including a table top assembly, wherein both ends of the lower side of the table top assembly are provided with table leg assemblies hinged to the table top assembly, and a V-shaped support member is movably provided on the table leg assembly, and two groups of limit assemblies cooperating with the V-shaped support member for folding or unfolding the table leg assembly are symmetrically provided in the middle part of the lower side of the table top assembly.

[0005] Furthermore, the limiting assembly includes a U-shaped piece whose open end is fixed to the table top assembly, and the U-shaped piece is provided with a long sliding hole that slides with the contracted end of the V-shaped support piece, and the central axis of the long sliding hole is arranged parallel to the central axis of the table top assembly, and the long sliding hole is provided with an unfolding limiting hook groove on one side close to the table leg assembly and a folding limiting hook groove on the other side, and the inner cavity of the U-shaped piece is also provided with a spring assembly for limiting the V-shaped support piece in the limiting hook groove.

[0006] Furthermore, the spring sheet assembly includes a mounting plate fixed to the table top assembly and a first spring sheet and a second spring sheet arranged on both sides of the mounting plate, the first spring sheet extends obliquely toward the unfolding limit hook groove, and the second spring sheet extends obliquely toward the folding limit hook groove.

[0007] Furthermore, the limiting hook groove is bent downward, and the angle between the axis of the expansion limiting hook groove and the axis of the long sliding hole is less than 90°.

[0008] Furthermore, a mounting notch communicating with the long sliding hole is also provided in the middle of the U-shaped member.

[0009] Furthermore, the table top assembly includes a table top, and longitudinal support plates arranged at both ends of the bottom of the table top, a transverse support plate located on the central axis of the table top is provided between the two longitudinal support plates, the table leg assembly is hinged on the longitudinal support plate, and the limit assembly is fixed on the transverse support plate.

[0010] Furthermore, the table leg assembly includes a hinge shaft rotatably connected to the table top assembly, and two table legs are fixed to both ends of the hinge shaft.

[0011] Furthermore, the V-shaped support member includes a cross bar movably connected to the table leg assembly and a V-shaped tube fixed to the cross bar.

[0012] The beneficial effects of the utility model are as follows: the table board assembly is used to support items, and the table leg assembly is hinged at both ends of the lower side of the table board assembly to facilitate its rotation relative to the table board assembly, so that the table feet in the table leg assembly fit with the bottom surface of the table board assembly to be folded, or unfolded to be perpendicular to the table board assembly to support the table board assembly. The V-shaped support member is movably arranged on the table leg assembly, and the limit assembly on the lower side of the table board assembly cooperates with the V-shaped support member to limit the rotation angle of the table feet of the folding table, thereby ensuring the stability of the table feet of the folding table when folded or unfolded. When the table legs need to be unfolded, under the action of external force, the retracted end of the V-shaped support moves from the folding limit hook groove to the long sliding hole, and the V-shaped support squeezes the second spring piece to make the second spring piece move upward to make way. After the retracted end of the V-shaped support moves into the long sliding hole, it slides along the axial direction of the long sliding hole in the direction of the unfolding limit hook groove and squeezes the first spring piece to make it move upward and then enter the unfolding limit hook groove. At this time, the first spring piece restores its shape and presses on the retracted end of the V-shaped support, limiting the retracted end of the V-shaped support. At the same time, when the V-shaped support slides, it drives the table leg assembly to rotate relative to the table board assembly until it rotates to the table leg assembly The table legs are perpendicular to the table board assembly, supporting the table board assembly. At this time, the rotation angle of the table leg assembly can be locked, and a triangular support state is formed between the table leg assembly, the table board assembly, and the V-shaped support member, thereby ensuring the stability of the folding table when in use. Similarly, when the table legs need to be folded, the V-shaped support member squeezes the first spring piece under the action of external force, and slides out of the unfolding limit hook groove and slides into the folding limit hook groove, and enters the folding limit hook groove. Under the resetting action of the second spring piece, the contracted end of the V-shaped support member is stuck in the folding limit hook groove. At this time, the table leg assembly rotates around the table board assembly until it fits with the table board assembly and can maintain a folded state. In this way, the table legs can be easily unfolded or folded to reduce the volume of the table. The position of the table legs after unfolding or folding can also be self-locked and limited to ensure the stability of the folding table when folded or unfolded. It is easy to use and simple to operate.

DETAILED DESCRIPTION

[0018] With reference to the accompanying drawings, specific embodiments of the present invention will be described in detail.

[0019] Reference Figures 1 to 3 , the utility model provides an embodiment of a self-locking folding table.

[0020] A self-locking folding table includes a tabletop assembly 10, which is used to support items. Specifically, the tabletop assembly 10 includes a tabletop 11, and longitudinal support plates 12 arranged at both ends of the bottom of the tabletop 11, and a transverse support plate 13 located on the central axis of the tabletop 11 is arranged between the two longitudinal support plates 12. The arrangement of the longitudinal support plates 12 and the transverse support plates 13 not only improves the support strength of the tabletop 11, but also provides an installation support portion for the table leg assembly 20 and the limit assembly 40.

[0021] The lower ends of the table board assembly 10 are provided with table leg assemblies 20 hinged to the table board assembly 10. Furthermore, the table leg assembly 20 is hinged to the longitudinal support plate 12. It is convenient to rotate relative to the table board assembly 10, so that the table feet 22 in the table leg assembly 20 are fitted with the bottom surface of the table board assembly 10 for folding, or unfolded to be perpendicular to the table board assembly 10 to support the table board assembly 10. Specifically, the table leg assembly 20 includes a hinge shaft 21 rotatably connected to the table board assembly 10 for hinged connection with the bottom of the longitudinal support plate 12, and two table feet 22 are fixed at both ends of the hinge shaft 21 for supporting the table top 11. After the two table leg assemblies 20 are folded, they are staggered to avoid overlapping of the table feet after folding, thereby reducing the volume after folding and making it easier to carry. Furthermore, the axis of the two table feet 22 of the table leg assembly 20 on one side is located on the inner side of the axis of the two table feet 22 of the table leg assembly 20 on the other side.

[0022] The table leg assembly 20 is movably provided with a V-shaped support member 30, which can be used to cooperate with the table leg assembly 20 and the table board assembly 10 to triangularly support the table board assembly 10, thereby ensuring the stability of the folding table after unfolding, and facilitating the folding or unfolding of the table legs 22. Specifically, the V-shaped support member 30 includes a cross bar 31 movably connected to the table leg assembly 20 and a V-shaped tube 32 fixed to the cross bar 31. Furthermore, the two ends of the cross bar 31 are movably connected to the middle and upper parts of the two table legs 22 on the same side. The cross bar 31 can enhance the stability between the two table legs 22 and support the V-shaped tube 32.

[0023] Two groups of limit assemblies 40 are symmetrically provided in the middle of the lower side of the table top assembly 10, which cooperate with the V-shaped support member 30 to fold or unfold the table leg assembly 20. Furthermore, the limit assemblies 40 are fixed on the transverse support plate 13 to limit the rotation angle of the table legs 22 of the folding table, thereby ensuring the stability of the table leg assembly 20 of the folding table when folding or unfolding.

[0024] Furthermore, the limiting assembly 40 includes a U-shaped member 41 whose open end is fixed to the table top assembly 10. The U-shaped member 41 can be made of U-shaped steel. The U-shaped member 41 is provided with a long sliding hole 411 that slides with the contraction end of the V-shaped support member 30. Furthermore, the long sliding hole 411 slides with the contraction end of the V-shaped tube 32. The central axis of the long sliding hole 411 is arranged parallel to the central axis of the table top assembly 10, and the long sliding hole 411 is provided with an expansion limit hook groove 412 on one side close to the table leg assembly 20. When the contracted end of the V-shaped tube 32 is inserted into the expansion limit hook groove 412, the table foot 22 of the table leg assembly 20 is perpendicular to the table top 11, and the other side of the long sliding hole 411 is provided with a folding limit hook groove 413. When the contracted end of the V-shaped tube 32 is inserted into the folding limit hook groove 413, the table foot 22 of the table leg assembly 20 is fitted with the bottom of the table top 11. The inner cavity of the U-shaped part 41 is also provided with a spring assembly 42 for limiting the contracted end of the V-shaped support part 30 in the limit hook groove, so as to improve the stability of the contracted end of the V-shaped tube 32 in the limit hook groove, thereby ensuring the stability of the table foot 22 after expansion or folding.

[0025] Furthermore, the spring clip assembly 42 includes a mounting plate 421 fixed to the table top assembly 10 and a first spring clip 422 and a second spring clip 423 arranged on both sides of the mounting plate 421, the first spring clip 422 extends obliquely toward the direction of the unfolding limit hook groove 412, and when the contraction end of the V-shaped tube 32 is located in the unfolding limit hook groove 412, the first spring clip 422 is pressed against the contraction end of the V-shaped tube 32 so that it can remain in the unfolding limit hook groove 412, thereby improving the stability of the table leg 22 when unfolded; the second spring clip 423 extends obliquely toward the direction of the folding limit hook groove 413, and when the contraction end of the V-shaped tube 32 is located in the folding limit hook groove 413, the second spring clip 423 is pressed against the contraction end of the V-shaped tube 32 so that it remains in the folding limit hook groove 413, thereby improving its stability after folding. Furthermore, the limiting hook groove is bent downward, and the angle between the axis of the expansion limiting hook groove 412 and the axis of the long sliding hole 411 is less than 90°, which further improves the stability of the V-shaped tube 32 when it is located in the limiting hook groove. Furthermore, the middle part of the U-shaped member 41 is also provided with an installation notch 414 connected to the long sliding hole 411, and the installation notch 414 corresponds to the middle part of the installation piece 421, so as to facilitate the installation of the contracted end of the V-shaped tube 32 into the long sliding hole 411.

[0026] When the table legs need to be unfolded, under the action of external force, the retracted end of the V-shaped support member 30 moves from the folding limit hook groove 413 to the long sliding hole 411, and the V-shaped support member 30 squeezes the second spring piece 423 to make the second spring piece 423 move upward to make way. After the retracted end of the V-shaped support member 30 moves into the long sliding hole 411, it slides along the axial direction of the long sliding hole 411 toward the unfolding limit hook groove 412 and squeezes the first spring piece 422 to make it move upward and then enter the unfolding limit hook groove 412. At this time, the first spring piece 422 restores its shape and presses on the retracted end of the V-shaped support member 30, limiting the retracted end of the V-shaped support member 30. At the same time, when the V-shaped support member 30 slides, it drives the table leg assembly 20 to rotate relative to the table board assembly 10 until it rotates to the table leg assembly The table leg 22 of the component 20 is perpendicular to the table board assembly 10 and supports the table board assembly 10. At this time, the rotation angle of the table leg assembly 20 can be locked, and a triangular support state is formed between the table leg assembly 20, the table board assembly 10 and the V-shaped support component 30, thereby ensuring the stability of the folding table when in use; similarly, when the table leg needs to be folded, the V-shaped support component 30 squeezes the first spring piece 422 under the action of external force, and slides out of the unfolding limit hook groove 412 to slide into the folding limit hook groove 413, and enters the folding limit hook groove 413. Under the resetting action of the second spring piece 423, the contracted end of the V-shaped support component 30 is stuck in the folding limit hook groove 413. At this time, the table leg assembly 20 rotates around the table board assembly 10 until it is in contact with the table board assembly 10 and can maintain a folded state.
