Description

TECHNICAL FIELD

[0001] The utility model relates to the field of sports equipment, especially an automatic folding and locking billiard table. BACKGROUND

[0002] At present, most of the foldable billiard tables on the market use hinge structures to fix the table top and the legs. When the lock is dropped, the user needs to use his hand to straighten the hinge until it reaches the dead point to ensure that the billiard table is locked. If the customer forgets to lock the hinge, the billiard table may fall over when it is pushed or pulled. At the same time, when the billiard table is folded for storage, the user needs to manually release the dead point of the hinge first. If the customer forgets to release the dead point, the billiard table may not be folded, or even when a lot of force is used to fold it, the hinge may be damaged.

[0003] To avoid the situation that the user forgets to drop the lock or unlock, an automatic folding and locking billiard table is developed, which is convenient for the user to operate and avoids the billiard table collapsing or the billiard table components being damaged due to the customer's incorrect operation.

[0041] As shown in the accompanying drawings, Figures 1-4 The embodiment provides an automatic folding and locking billiard table, which comprises:

[0042] The table top 10 is used for training table tennis.

[0043] The leg assembly is arranged below the table top 10 and comprises two first legs 20 and two second legs 60, and is used for supporting the table top 10.

[0044] The pull rod assembly 30 is arranged below the table top 10 and comprises a hand pull rod 31 and two linkage rods 32 fixed at both ends of the hand pull rod 31, the two linkage rods 32 are parallel to each other and perpendicular to the hand pull rod 31 in the horizontal plane, as shown in the accompanying drawings, Figure 1 The hand pull rod 31 and the two linkage rods 32 are respectively located on the three side edges of the table top 10, and the hand pull rod 31 is pulled, and the linkage rods 32 move synchronously.

[0045] The vertical locking assembly 50 has two groups, which are respectively arranged at one end of the linkage rod 32 away from the hand pull rod 31, and the vertical locking assembly 50 comprises:

[0046] The lock buckle housing 51 is a reversed U-shaped plate structure, which is fixed to the bottom of the table top 10 near the end of the linkage rod 32. A hollow accommodating cavity 52 is formed in the lock buckle housing 51. The two ends of the accommodating cavity 52 are open. A sliding groove 53 extending along the length direction is formed in the side of one end of the lock buckle housing 51. A connecting bolt 54 is transversely arranged in the sliding groove 53. The end of the linkage rod 32 is fixed to the end of the connecting bolt 54 arranged outside the lock buckle housing 51. The linkage rod 32 drives the connecting bolt 54 to move in the sliding groove 53. An extension hole 511 is formed in the top surface of the lock buckle housing 51 above the sliding groove 53. The extension hole 511 is a rectangular hole.

[0047] The locking plate 55 is arranged in the accommodating cavity 52. The hinged end 553 of the locking plate 55 is hinged to one end of the lock buckle housing 52. The other end of the locking plate 55 is a free end 552, which extends out of the lock buckle housing 51 through the extension hole 511 and abuts against the upper side of the connecting bolt 54.

[0048] A locking groove 512 extending downward is formed in the top surface of the other end of the lock buckle housing 51. The locking plate 55 has a protruding locking pawl 551 at the position of the locking groove 512.

[0049] A locking hook 61 is arranged on the second leg 60 near the lock buckle housing 51. When the table top 10 is vertically placed, the locking hook 61 is arranged in the locking groove 512 and cooperates with the locking pawl 551.

[0050] The locking hook 61 is a reversed U-shaped structure. The locking pawl 551 limits the transverse rod of the locking hook 61.

[0051] When the table top 10 is lifted from the side near the hand-pulling rod to the vertical placement, the locking hook 61 is arranged in the locking groove 512. The linkage rod 32 slides downward under the action of gravity, drives the connecting bolt 54 to move along the sliding groove 53, and drives the free end 552 of the locking plate 55 to move upward. The locking plate 55 rotates counterclockwise around the hinge point, and the locking pawl 551 moves downward to limit and lock the locking hook 61. The table top cannot be moved, and the billiard table is folded and locked without manual operation, which increases the safety.

[0052] The free end 552 of the locking plate 55 extends upward relative to the hinged end 553, so that the free end 552 abuts against the upper side of the connecting bolt 54. The length of the free end 552 is greater than the length of the sliding groove 53, so that when the connecting bolt 54 is located at the limit position of the sliding groove 53 away from the hinged end 553 of the locking plate, the free end 552 always abuts against the upper side of the connecting bolt 54.

[0053] As Figure 4As shown, the accommodating cavity 51 is further internally provided with a torsion spring 56 coaxially hinged with the locking plate 55, when the vertical locking assembly 50 is in the locked state, the connecting bolt 54 is driven to move downward by the downward movement of the linkage rod 32, the free end of the locking plate 55 is subjected to the upward pressure of the connecting bolt, at this time the torsion spring is in the unfolded state, the two ends of the locking plate 55 are subjected to the oblique upward elastic force of the torsion spring 56, the locking pawl 551 of the locking plate 55 limits and locks the locking hook 61, so that the locking pawl 551 can stably limit the locking hook 61 in the locking groove 512; when the vertical locking assembly 50 is unlocked, the connecting bolt 54 is driven to move upward by the upward movement of the linkage rod 32, under the action of the torsion spring 56, the free end of the locking plate 55 rotates, then the locking pawl 551 of the locking plate 55 also rotates, when the connecting bolt 54 moves upward by a certain distance and stops, the free end of the locking plate 55 also stops rotating, at this time the torsion spring is in the compressed state, the locking pawl 551 rotates to the position of unlocking the locking hook 61, and the locking hook 61 is separated from the locking groove 512.

[0054] As shown in the figure, Figure 5 The locking hook 61 is a reverse U-shaped frame structure including a locking cross rod 611, and the locking pawl 551 limits the locking cross rod 611 to achieve vertical locking of the table top.
