Description

Technical Field

[0001] The utility model belongs to the technical field of folding tables, and in particular relates to a folding table with stable support. Background Art

[0002] A folding table is a commonly used work tool in daily life. Existing folding tables generally include a work surface and a supporting frame. The work surface is hinged to the supporting frame. A connecting rod for locking is provided between the work surface and the supporting frame. One end of the connecting rod is hinged to the supporting frame, and the other end of the connecting rod is snap-connected to the work surface. Since processing operations need to be performed on the work surface, the work surface is prone to vibration, and the connecting rod is easily detached from the work surface, resulting in a poor locking effect of the supporting frame. When the existing supporting frame is in a folded state, the work surface does not have a separate locking mechanism, so that the supporting frame will rotate relative to the work surface when folded, resulting in certain safety hazards when the folding table is carried. Therefore, it is necessary to design a folding table with stable support to overcome the above difficulties. Summary of the invention

[0003] In view of the problems existing in the prior art, the utility model designs a folding table with stable support. The utility model arranges a locking component under the table top body. When the supporting leg is in a folded state, the first connecting rod is clamped by the lock; when the supporting leg is in an unfolded state, the supporting connecting rod is clamped by the lock, so that the locking is reliable and the supporting structure is stable.

[0004] The invention objective of the utility model is achieved through the following technical solutions: a folding table with stable support, comprising a desktop body, a pair of supporting legs are arranged at the bottom of the desktop body, each of the supporting legs is hinged to the desktop body; a supporting assembly for supporting is also arranged between the supporting legs and the desktop body; the supporting assembly comprises a first connecting rod and a supporting connecting rod, the first connecting rod is hinged to the supporting legs, and the supporting connecting rod is hinged to the first connecting rod; a locking assembly for locking the supporting assembly is provided at the bottom of the desktop body, the locking assembly comprises a mounting base, a lock and a torsion spring assembly, a first pin shaft is provided between the lock and the mounting base to hinge the two, and a torsion spring assembly is provided on the first pin shaft; when the supporting legs are unfolded away from the desktop body, the supporting connecting rod is stuck on the lock buckle, and when the supporting legs are folded close to the desktop body, the first connecting rod is stuck on the lock buckle.

[0005] Preferably, the supporting leg comprises a mounting bar and a supporting base, the mounting bar is fixedly mounted on the bottom of the desktop body, and the supporting base is hinged to the mounting bar; the supporting base comprises a strip connecting rod and a supporting bending piece, and the strip connecting rods are arranged in pairs; the end of the supporting bending piece is fixedly connected to the strip connecting rod, and the strip connecting rod is hinged to the mounting bar; when the supporting leg and the desktop body are arranged parallel to each other, the supporting leg is in a folded state, and when the supporting leg and the desktop body are arranged perpendicular to each other, the supporting leg is in an unfolded state.

[0006] By providing a mounting strip, the support stand can be fixed conveniently; by hingedly connecting the mounting strip and the support base, the support stand can rotate relative to the desktop body. By providing a support bending piece on the support base, the support stand can be placed on a horizontal plane conveniently, and the support stand has a better supporting effect.

[0007] Preferably, a first fastener is provided between the installation strip and the desktop body to fix the two, and a first hinge axis is provided between the installation strip and the strip-shaped connecting rod to hinge the two.

[0008] Preferably, the strip connecting rod is provided with a support assembly hinged thereto; the support assembly comprises a first connecting rod and a support connecting rod, both ends of the first connecting rod are mounted on the strip connecting rod and hinged to the strip connecting rod; the end of the support connecting rod is hinged to the first connecting rod, and the end of the support connecting rod is inserted into the first connecting rod.

[0009] The support link is a cylindrical metal part that is integrally bent and formed, for example, a steel bar is integrally bent and formed; after the support link is bent and formed, it includes a short straight rod, and two symmetrical long straight rods are formed at both ends of the short straight rod; because the support link is an integrally bent structure, the support strength is high and the support is stable. The support link can rotate relative to the first link, and when the support tripod is in a folded state, the support link rotates synchronously, and the support link rotates to a position that fits the desktop body, so that the support link can be stuck in the lock of the mounting base. When the support tripod is in an unfolded state, the support link rotates synchronously, so that the support link forms an angle with the strip connecting rod, so that the top of the support link can be stuck in the lock; at this time, the support link, the support tripod and the desktop body form a stable triangular structure with a good support effect.

[0010] Preferably, the strip connecting rod includes a horizontal strip plate and a vertical strip plate, and the horizontal strip plate and the vertical strip plate are integrally formed and adjacently arranged; when the supporting leg is in a folded state, the horizontal strip plate and the desktop body are arranged parallel to each other, and when the supporting leg is in a folded state, the vertical strip plate and the desktop body are arranged perpendicular to each other; the first connecting rod is installed on the vertical strip plate; a retaining spring for limiting is provided at the end of the first connecting rod, and the retaining spring is arranged adjacent to the end of the supporting connecting rod.

[0011] The strip connecting rod includes a horizontal strip plate and a vertical strip plate, so that the axial structure of the strip connecting rod is more stable. Since the first connecting rod is pressed on the vertical strip plate, the horizontal strip plate will limit the support connecting rod. When the support leg is in a folded state, the support connecting rod is between the horizontal strip plate and the desktop body; at this time, the support connecting rod is limited by the horizontal strip plate, and the support connecting rod cannot rotate away from the desktop body, which takes up little space and is convenient to carry; when the folding table is in a folded state, the support leg and the support assembly will not rotate, and the carrying process is safer. The first connecting rod is provided with a groove for installing a retaining spring, and the retaining spring is provided to prevent the support connecting rod from axially moving relative to the first connecting rod.

[0012] Preferably, a first cross bar and a second cross bar are provided between the two strip-shaped connecting rods, and the first cross bar and the second cross bar are cross-arranged; both ends of the first cross bar are fixedly connected to the strip-shaped connecting rod, and both ends of the second cross bar are fixedly connected to the strip-shaped connecting rod; the first cross bar and the second cross bar are both arranged close to the lower end surface of the desktop body.

[0013] By providing the first cross bar and the second cross bar, the connection strength of the support base is higher and the supporting effect of the support stand is better.

[0014] Preferably, the locking assembly also includes a second fastener for fixing; a second fastener for fixing the mounting base and the desktop body is provided between the mounting base and the desktop body, and a waist-shaped hole for inserting the second fastener is provided on the mounting base; a mounting hole for installing the first pin shaft is provided on the mounting base, and the torsion spring assembly and the lock buckle are both inserted and installed on the first pin shaft; a locking portion for placing the supporting assembly is provided on the lock buckle, and the outer contour of the locking portion is adapted to the outer contour of the first connecting rod, and the outer contour of the locking portion is also adapted to the outer contour of the supporting connecting rod; a yield groove for placing the supporting assembly is provided on the mounting base, and when the free end of the lock buckle is pressed, the locking portion moves relative to the yield groove, and the free end of the lock buckle extends from the inside of the mounting base to the outside of the mounting base.

[0015] In the default state, the torsion spring assembly presses the end of the lock buckle, and the free end of the lock buckle will be tilted relative to the desktop body, and the free end of the lock buckle will be against the inner wall of the mounting base. When the first connecting rod or the supporting connecting rod is placed in the locking part of the lock buckle, the first connecting rod or the supporting connecting rod can be firmly stuck in the locking part. Because when the first connecting rod or the supporting connecting rod wants to be separated from the locking part, the first connecting rod or the supporting connecting rod will drive the lock buckle to move out of the yielding groove, at this time, the free end of the lock buckle will be against the inner wall of the mounting base, and the first connecting rod or the supporting connecting rod cannot drive the lock buckle to rotate. Therefore, the lock buckle can stably lock the first connecting rod and the supporting connecting rod through the elastic force of the torsion spring assembly, and prevent the first connecting rod and the supporting connecting rod from being separated from the mounting base. When unlocking is required, the free end of the lock buckle is pressed by external force, and the free end of the lock buckle moves close to the desktop body, then the locking part will be separated from the first connecting rod or the supporting connecting rod, then the first connecting rod or the supporting connecting rod can be rotated relative to the mounting base, so that the locking assembly will be in an unlocked state. At this time, the torsion spring assembly is in an elastic deformation state, and when the free end of the lock catch is released, the locking assembly automatically returns to the locked state.

[0016] Preferably, the torsion spring assembly includes a torsion spring body, an elastic portion is provided in the middle of the torsion spring body, and elastic pins are provided in pairs at the end of the torsion spring body; the elastic portion abuts against the upper end surface of the lock buckle, and the free ends of the elastic portion and the lock buckle are respectively arranged on both sides of the first pin shaft; in the default state, the torsion spring assembly is in an elastic deformation state and the upper end surface of the lock buckle abuts against the inner wall of the mounting base, and the locking assembly is in a locked state when the upper end surface of the lock buckle abuts against the inner wall of the mounting base.

[0017] The elastic pin of the torsion spring body rests against the inner wall of the mounting base, and the elastic part is stuck in the end of the lock buckle close to the first pin shaft, so that the free end of the lock buckle will be tilted and rest against the inner wall of the mounting base in the default state, so that the locking assembly can be stably in the locked state; when it is necessary to switch from the locked state to the unlocked state, external force is required to press the free end of the lock buckle, so that the locking part can move relative to the mounting base, and then the first connecting rod or the supporting connecting rod will lose the limit.

[0018] Preferably, the lower end surface of the desktop body is provided with a pair of protrusions, and the protrusions are arranged close to the edge of the desktop body; the protrusions are in the shape of long strips, and the protrusions and the supporting legs are arranged parallel to each other.

[0019] The protrusions are provided to facilitate grabbing the desktop body during transportation.

[0020] Compared with the prior art, the utility model has the following beneficial effects: the utility model is provided with a support leg hinged thereto below the desktop body, which is convenient for unfolding and folding. A support assembly is provided between the desktop body and the support leg, and a locking assembly for locking is provided at the bottom of the desktop body. When the support leg is in an unfolded state, the support connecting rod is stuck in the lock buckle of the mounting base, so that the support leg can be stably in an unfolded state, and the unfolded state is stable and the supporting effect is good.

A torsion spring assembly is provided on the locking assembly, and the lock buckle is locked by the torsion spring assembly, and the lock buckle is locked reliably and stably. The lock buckle assembly is installed in the mounting base through the first pin shaft, and the lock buckle can be unlocked by pressing the lock buckle, which is convenient to unlock. At the same time, the first connecting rod of the support assembly and the support connecting rod are combined to form a stable triangular support structure with good supporting effect; the support connecting rod is bent and formed as a whole, and the support strength is higher and the support is more reliable.

[0034] In the specific operation process of this embodiment, the locking assembly 4 is in a locked state in the default state; when the folding table needs to be used, the support leg 2 is rotated so that it is perpendicular to the desktop body 1, and the support leg 2 is in an unfolded state; then the support link 32 is rotated so that the top of the support link 32 is stuck in the locking portion 48 of the lock 42. Before the support link 32 is placed in the locking portion 48, the user needs to press the lock 42 so that the free end of the lock 42 is close to the desktop body 1, so that the locking assembly 4 will be in an unlocked state, and the torsion spring assembly 43 is in an elastic deformation state. When the support link 32 is stuck in the locking portion 48, the free end of the lock 42 is released, so that the locking assembly 4 automatically returns to the default locked state; then the support leg 2 can be stably in the unfolded state, and the supporting effect is good.

[0035] When the folding table needs to be stored, the locking assembly 4 is unlocked by pressing the lock 42, and then the supporting link 32 is rotated to disengage the lock 48; then the supporting leg 2 is rotated to fit the bottom of the table body 1. When the supporting leg 2 approaches the table body 1, the first link 31 simultaneously approaches the lock 42, and then the user presses the lock 42 to unlock the locking assembly 4, and then places the first link 31 into the locking portion 48, and finally releases the free end of the lock 42, and the locking assembly 4 is locked; at this time, the supporting leg 2 is in a folded state, and the supporting assembly 3 cannot rotate relative to the table body 1.

[0036] The working principle of the locking assembly 4 is as follows: in the default state, the torsion spring assembly 43 presses the end of the lock buckle 42, and the free end of the lock buckle 42 will be tilted relative to the desktop body 1, and the free end of the lock buckle 42 will be against the inner wall of the mounting base 41. When the first connecting rod 31 or the supporting connecting rod 32 is placed in the locking portion 48 of the lock buckle 42, the first connecting rod 31 or the supporting connecting rod 32 can be firmly stuck in the locking portion 48. Because when the first connecting rod 31 or the supporting connecting rod 32 wants to be separated from the locking portion 48, the first connecting rod 31 or the supporting connecting rod 32 will drive the lock buckle 42 to move out of the clearance groove 49, at this time, the free end of the lock buckle 42 will be against the inner wall of the mounting base 41, and the first connecting rod 31 or the supporting connecting rod 32 cannot drive the lock buckle 42 to rotate. Therefore, the lock buckle 42 can stably lock the first connecting rod 31 and the supporting connecting rod 32 through the elastic force of the torsion spring assembly 43. When unlocking is required, the free end of the lock buckle 42 is pressed by external force, and the free end of the lock buckle 42 moves closer to the desktop body 1, so that the locking portion 48 will be separated from the first connecting rod 31 or the supporting connecting rod 32, and the first connecting rod 31 or the supporting connecting rod 32 can be rotated relative to the mounting base 41, so that the locking assembly 4 will be in the unlocked state. At this time, the torsion spring assembly 43 is in an elastic deformation state, and when the free end of the lock buckle 42 is released, the locking assembly 4 automatically returns to the locked state.
