The four legs are fixed to the bottom of the support tube, the support plate is mounted on top of the support tube, and the tabletop is fixed to the support plate. While this type of table can meet certain usage needs, its disadvantage is that because the four legs are all equidistant from the tabletop, in uneven outdoor environments, not all four legs can touch the ground, causing the table to be unbalanced and affecting its usability. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a base for an automatic leveling table and an automatic leveling table.

[0004] The technical solution of the present invention is as follows:

[0005] A base for an automatic leveling table includes an outer tube, an inner tube, a support plate, front and rear legs, left and right legs, a first spring, and a locking mechanism. The left and right legs have grooves on their front and rear sides. The inner tube is slidably disposed within the outer tube. The left and right legs are fixed to the bottom of the outer tube, and the front and rear legs are fixed to the bottom of the inner tube. The middle portions of the front and rear legs are located within the grooves. The support plate is mounted on the top of the outer tube. The first spring is sleeved on the inner tube, with its top end fixed to the inside of the outer tube and its bottom end fixed to the inner tube. The locking mechanism is mounted on the outer tube, with its locking end locked to the inner tube. When the locking mechanism is released, the inner tube moves downward along the outer tube under the force of the first spring.

[0006] Preferably, the locking mechanism includes an upper pressure ring, a lower pressure ring, a second spring, a support block, an upper pull rod, a lower pull rod, a sleeve, a wrench, and a pull rope. The sleeve is fixedly sleeved on the upper part of the outer tube, and the outer tube has a slot at the sleeve. The support block is vertically installed on the inner side of the upper part of the outer tube, with an upper support groove at its upper end and a lower support groove at its lower end. The upper pressure ring is sleeved on the inner tube, with its right end supported on the upper support groove. The lower pressure ring is sleeved on the inner tube, with its right end supported on the lower support groove. The second spring is sleeved on the inner tube and located between the upper pressure ring and the lower pressure ring. The wrench is installed on the sleeve, with its extension end extending into the sleeve. The right end of the upper pull rod is hinged to the upper pressure ring, and its left end is connected to the extension end of the wrench through the pull rope. The right end of the lower pull rod is hinged to the lower pressure ring, and its left end is connected to the extension end of the wrench through the pull rope.

[0007] Preferably, the inner side of the sleeve is provided with a fixing block, and the fixing block is provided with a horizontal sliding groove, and the left end of the upper pull rod and the left end of the lower pull rod are both slidably disposed in the sliding groove.

[0008] Preferably, the base of the automatic leveling table further includes washers, the top of the left and right support legs is provided with a recess, the washers are installed on the recess, and the top of the first spring is fixed to the bottom of the washers.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] To illustrate the technical solution described in this invention, specific embodiments are described below.

[0021] Example 1

[0022] like Figures 1 to 3 As shown, the base of the automatic leveling table in this embodiment includes an outer tube 1, an inner tube 2, a support plate 3, front and rear support legs 4, left and right support legs 5, a first spring 6, and a locking mechanism 7. The front and rear sides of the left and right support legs 5 are provided with grooves 51. The inner tube 2 is slidably disposed inside the outer tube 1. The left and right support legs 5 are fixed to the bottom of the outer tube 1. The front and rear support legs 4 are fixed to the bottom of the inner tube 2. The middle part of the front and rear support legs 4 is located in the grooves 51. The support plate 4 is installed on the top of the outer tube 1. The first spring 6 is sleeved on the inner tube 2, with its top end fixed to the inside of the outer tube 1 and its bottom end fixed to the inner tube 2. The locking mechanism 7 is installed on the outer tube 1, and its locking end is locked to the inner tube 2. When the locking mechanism 7 is released, the inner tube 2 moves down along the outer tube 1 under the action of the first spring 6. When the table is placed outdoors or on uneven ground, the locking mechanism 7 is released. Under the force of the first spring 6, the inner tube 2 moves downward along the outer tube 1, causing the front and rear support legs 4 on the inner tube 2 to press down onto the ground, allowing the table base to automatically level and rotate on uneven ground. When storing, the inner tube 2 can be rotated so that its bottom front and rear support legs 4 overlap the left and right support legs 5 of the outer tube 1, pressing down on the outer tube 1 and locking the locking mechanism 7. In this embodiment, the base of the self-leveling table can achieve automatic leveling of the table, adapting to uneven ground; it also facilitates the storage and carrying of the table.

[0023] In this embodiment, the locking mechanism 7 includes an upper pressure ring 71, a lower pressure ring 72, a second spring 73, a support block 74, an upper pull rod 75, a lower pull rod 76, a sleeve 77, a wrench 78, and a pull rope 79. The sleeve 77 is fixedly sleeved on the upper part of the outer tube 1. The outer tube 1 has a slot 11 at the sleeve. The support block 74 is vertically installed on the inner side of the upper part of the outer tube 1, with an upper support groove 741 at its upper end and a lower support groove 742 at its lower end. The upper pressure ring 71 is sleeved on the inner tube 2, with its right end supported on the upper support groove 741. The lower pressure ring 72 is sleeved on the inner tube 2, and its right end is supported on the lower support groove 742. The second spring 73 is sleeved on the inner tube 1 and located between the upper pressure ring 71 and the lower pressure ring 72. The wrench 78 is mounted on the sleeve 77, and its extension end extends into the sleeve 77. The right end of the upper pull rod 75 is hinged to the upper pressure ring 71, and its left end is connected to the extension end of the wrench 78 through the pull rope 79. The right end of the lower pull rod 76 is hinged to the lower pressure ring 72, and its left end is connected to the extension end of the wrench 78 through the pull rope 79. In the locked state, the right ends of the upper pressure ring 71 and the lower pressure ring 72 are supported on the upper support groove 741 and the lower support groove 742, respectively. Under the force of the second spring 73, the upper pressure ring 71 and the lower pressure ring 72 tilt upward and downward respectively, so that the inner sides of the upper pressure ring 71 and the lower pressure ring 72 press against the inner tube 1, preventing the inner tube 1 from moving. When the wrench 78 is turned, the wrench 78 drives the pull rope 79 to move to the left. The pull rope 79 drives the upper pull rod 75 and the lower pull rod 76 to move to the left, and at the same time, it drives the upper pressure ring 71 to press downward and the lower pressure ring 72 to press upward, so that the inner sides of the upper pressure ring 71 and the lower pressure ring 72 remain parallel to the inner tube 2, releasing the lock on the inner tube 2, and allowing the inner tube 2 to move downward under the force of the first spring 6. This locking mechanism 7 can also adopt other structures, as long as it can achieve the locking and unlocking of the inner tube 2.

[0024] In this embodiment, a fixing block 771 is provided on the inner side of the sleeve 77, and a sliding groove 772 is provided on the fixing block 771 laterally. The left end of the upper pull rod 75 and the left end of the lower pull rod 76 are slidably disposed in the sliding groove 772, so that when the wrench 78 is turned, the pull rope 79 drives the upper pull rod 75 and the lower pull rod 76 to move. The bottom of the left and right support legs 5 and the front and rear support legs 4 are provided with pads 10 to facilitate the support legs to be supported on the ground.

[0025] In this embodiment, the base of the automatic leveling table also includes a washer 12, and the top of the left and right support legs 4 is provided with a recess 52. The washer 12 is installed on the recess 52, and the top of the first spring 6 is fixed to the bottom of the washer 12 to facilitate the fixation of the first spring 6.

[0026] In this embodiment, the base of the automatic leveling table further includes a limiting component 13, which is installed between the outer tube 1 and the inner tube 2. The limiting component 13 includes a third spring 131 and a limiting block 132. The limiting block 122 is fixed on the inner tube 1 and located above the washer 12. The third spring 131 is sleeved on the inner tube 1 and located between the limiting block 132 and the washer 12. By utilizing the cooperation of the limiting block 132 and the third spring 131, after the inner tube 2 moves down a certain distance under the action of the first spring 6, the limiting block 132 is locked on the third spring 131, preventing the inner tube 2 from moving further down, effectively preventing the inner tube 2 from detaching from the outer tube 1.

[0027] Example 2

[0028] like Figures 1 to 4 As shown, based on Embodiment 1, the self-leveling table in this embodiment includes a tabletop 14 and a base, with the tabletop 14 mounted on the support plate 3. When the table is placed outdoors or on uneven ground, the locking mechanism 7 is released, and the inner tube 2 moves downward along the outer tube 1 under the force of the first spring 6, causing the front and rear support legs 4 on the inner tube 2 to press down onto the ground, allowing the table to automatically level and rotate on uneven ground. When storing, the inner tube 2 can be rotated so that its bottom front and rear support legs 4 overlap the left and right support legs 5 of the outer tube 1, pressing the outer tube 1 down and locking the locking mechanism 7. This embodiment of the self-leveling table can achieve automatic leveling, adapting to uneven ground; it is also convenient for storage and carrying.

[0029] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
