DETAILED DESCRIPTION

[0030] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0031] The following is combined with Figure 1-Figure 12 This embodiment is described in further detail.

[0032] See also Figure 1-Figure 4 In this embodiment, an anti-skid structure attached to a leveling tripod includes a tripod body, the tripod body includes a base 100 and a support assembly rotatably arranged outside the base 100, the support assembly includes a leg 110 and a foot 111 arranged at the bottom thereof, an anti-skid assembly is arranged at the outer side wall of the foot 111, the anti-skid assembly includes an anti-slip plate 310 rotatably arranged around the foot 111, a fixing cavity 400 is arranged in the foot 111, and a fixing cavity 400 is arranged in the fixing cavity 400 for driving The driving component rotates the anti-skid plate 310 to fit the ground, and the support leg 111 is also provided with a retaining component for fixing the anti-skid plate 310 that fits the ground; a suction cup 300 is provided at the bottom end of the support leg 111, and the suction cup 300 is provided with an air intake component that extends into the support leg 111. When the driving component drives the anti-skid plate 310 to rotate away from the ground, it can also drive the air intake component to intake air into the suction cup 300, and the base 100 is provided with a locking component for locking the stored support leg 110.

[0033] In this embodiment, a hinge groove for the upper end of the corresponding leg 110 to extend into is provided on the outer wall of the base 100, and the upper end of the leg 110 is rotatably installed in the hinge groove through a hinge shaft, thereby realizing the rotatable installation of the leg 110 on the base 100; When it is actually used, after the locking assembly is released to lock the legs 110, the legs 110 are rotated and unfolded, so that the bottom ends of the legs 111 touch the ground, so that they support the base 100; at this time, the level is placed on the base 100 to perform leveling measurement; Specifically, the angle at which the support legs 111 are unfolded in this embodiment is fixed, which can better ensure that the bottom end of the support legs 111 contacts the ground; Among them, through the arrangement of the anti-skid assembly and the driving assembly, when the support foot 111 contacts the ground, the anti-skid plate 310 is rotated by the driving assembly to contact the ground, so as to increase the contact area between the support foot 111 and the ground, thereby increasing the friction between the support foot 111 and the ground, so that it can maintain good stability even when used on a smooth ground; when the measurement work is completed, the anti-skid plate 310 can be rotated to separate from the ground and fit on the outer side wall of the support foot 111, so as to reduce the space it occupies and make it easy to transport and carry; Specifically, in order to improve the anti-skid effect of the anti-skid plate 310, an anti-skid pad is provided on the side of the anti-skid plate 310 that contacts the ground; Among them, through the setting of the driving component, when it is necessary to simultaneously rotate multiple anti-slip plates 310 located around the same foot 111, it is only necessary to operate the driving component once, without having to move multiple anti-slip plates 310 in sequence, which is more convenient; Among them, by setting the holding component, the anti-slip plate 310 can be kept in contact with the ground, so that it does not need to be manually held when in use; Among them, through the arrangement of the suction cup 300 and the air intake assembly, the suction cup 300 is made of soft material, and a closed cavity is arranged in the suction cup 300, so that when the support leg 111 contacts the ground, the air in the closed cavity is discharged from the edge of the suction cup 300 by pressing, and a negative pressure is formed in the closed cavity, so that the suction cup 300 is adsorbed on the smooth ground, thereby further making the connection between the support leg 111 and the ground more firmly; when the support leg 111 needs to be removed from the ground, the closed cavity can be connected with the outside air through the air intake assembly, so that the air pressure of the closed cavity and the outside is balanced, which is convenient for releasing the adsorption of the suction cup 300 on the ground, so that the support leg 111 can be removed from the ground; When the driving component drives the anti-slip plate 310 to rotate and store, it can drive the air intake component to work, that is, when the driving component drives the anti-slip plate 310 to leave the ground, it can also drive the outside air to automatically enter the closed cavity, so as to facilitate the removal of the support leg 111 from the ground, thereby facilitating the rotation of the support leg 110 for storage; Among them, through the setting of the locking component, when the base 100 and the leg 110 need to be transported, the leg 110 can be rotated to make it close to the base 100, and then the leg 110 can be fixed by the locking component, so that the leg 110 is not easy to separate from the base 100 and shake during transportation.

[0034] like Figure 1-11 As shown, in the present embodiment, hinge seats 301 are provided on the side walls around the supporting foot 111 and at the bottom end, and one end of the anti-slip plate 310 is hingedly connected to the corresponding hinge seat 301; the driving assembly includes a movable frame 320 which is sleeved on the outside of the supporting foot 111, and a hinge rod 311 is provided on the outer side wall of the movable frame 320, and the other end of the hinge rod 311 is hingedly connected to the corresponding anti-slip plate 310, and an upward movable plate 420 is provided in the fixed cavity 400 through the first spring 1101, and a slot 401 connecting to the fixed cavity 400 is provided on the outer side wall of the supporting foot 111 along its height direction, and the movable plate 420 is connected to the movable frame 320 through a support plate passing through the slot 401.

[0035] When the movable frame 320 moves upward, the hinge rod 311 is driven upward, thereby driving the end of the anti-skid plate 310 close to the hinge seat 301 to rotate around the hinge seat 301, and finally the anti-skid plate 310 is separated from the ground and close to the corresponding outer side surface of the support foot 111. When the movable frame 320 moves downward, the hinge rod 311 is driven downward, and finally the anti-skid plate 310 is separated from the support foot 111 and close to the ground. One end of the first spring 1101 is pressed against the bottom wall of the fixing cavity 400, and the other end is pressed against the movable plate 420. Under the thrust of the first spring 1101, the movable frame 320 can maintain the upward movement trend, that is, after the anti-skid plate 310 is released, the anti-skid plate 310 can automatically rotate, so that the anti-skid plate 310 is separated from the ground and close to the support foot 111. This process does not require manual movement of the movable frame 320, which is more convenient.

[0036] like Figure 1-8 As shown, in this embodiment, a locking hole is provided on the end face of the anti-slip plate 310, a retaining cavity 800 with an opening at the lower end is provided on the bottom end face of the support leg 111, and a cover plate 620 is provided at the opening of the retaining cavity 800; the retaining assembly includes a rotating rod 410 rotatably arranged in the retaining cavity 800, a gear 831 is provided on the outer sleeve of the rotating rod 410, a first rack 810 and a second rack 330 meshing with the gear 831 are relatively provided in the retaining cavity 800, the first rack 810 and the second rack 330 can penetrate the support leg 111 and extend into the corresponding locking holes, and a guide rod 841 for passing the second rack 330 is also provided in the retaining cavity 800, and a second spring 842 is provided on the guide rod 841, and the second spring 842 is used to drive the second rack 330 to extend into the locking hole.

[0037] In this embodiment, the rotation of the rotating rod 410 drives the gear 831 to rotate, thereby driving the first rack 810 and the second rack 330 to move away from or approach each other. When the first rack 810 and the second rack 330 move away from each other, one end of the first rack 810 and the second rack 330 can extend into the locking hole, thereby preferably fixing the anti-slip plate 310 attached to the ground to prevent it from rotating and then leaving the ground. When the first rack 810 and the second rack 330 move closer to each other, one end of the first rack 810 and the second rack 330 can leave the locking hole, releasing the fixation of the anti-slip plate 310. Under the thrust of the first spring 1101, the anti-slip plate 310 leaves the ground and rotates in the direction close to the support foot 111. In actual use of this embodiment, the first rack 810 and the second rack 330 are matched with the side wall of the holding cavity 800 through a keyway. Through the above structure, the first rack 810 and the second rack 330 can maintain the state of aligning with the locking hole when moving; Among them, through the arrangement of the guide rod 841 and the second spring 842, the guide rod 841 passes through the second rack 330. Under the thrust of the second spring 842, the second rack 330 can always move in the direction close to the locking hole, without manually maintaining this state. The second spring 842 is sleeved outside the guide rod 841, thereby realizing the installation of the second spring 842 in the holding cavity 800; In this embodiment, in order to limit the moving distance of the first rack 810 and the second rack 330, a limit block 811 is provided at the side wall of the first rack 810 and the second rack 330, and the limit block 811 can prevent the first rack 810 and the second rack 330 from completely leaving the holding cavity 800; Among them, the locking holes are only arranged on the end walls of the two anti-slip plates 310 close to the first rack 810 and the second rack 330. One end of the first rack 810 and the second rack 330 extends into the locking holes in the corresponding anti-slip plates 310, so that the anti-slip plates 310 cannot rotate, thereby fixing the movable frame 320.

[0038] like Figure 1-7 As shown, in this embodiment, a mounting groove 630 is provided at the bottom end surface of the support leg 111, and a first air inlet hole 600 is provided at the side wall of the mounting groove 630; the air intake assembly includes an air intake block 610 extending into the mounting groove 630, and an air intake cavity 700 connected to the suction cup 300 is provided in the air intake block 610, and a second air inlet hole 711 is provided at the side wall of the air intake cavity 700 corresponding to the first air inlet hole 600, a movable piston 722 is provided in the air intake cavity 700 through a third spring 740, and an air duct 720 is provided in the piston 722 corresponding to the second air inlet hole 711, and the third spring 740 pushes the piston 722 to move upward to cause the air duct 720 and the second air inlet hole 711 to be misaligned.

[0039] In this embodiment, the lower end of the air intake block 610 is fixedly mounted on the suction cup 300, and the air intake chamber 700 therein is connected with the closed chamber. Under the thrust of the third spring 740, the piston 722 will remain located at the top of the air intake chamber 700, so that the air passage 720 and the second air intake hole 711 are misaligned. At this time, the air intake assembly is closed. When the suction cup 300 moves downward with the support foot 111, the air in the closed chamber is discharged from the edge of the suction cup 300, thereby keeping the suction cup 300 in a negative pressure state, which can increase the suction force between the support foot 111 and the ground. When the piston 722 moves downward, the air passage 720 corresponds to the second air intake hole 711, and the outside air can enter the air intake chamber 700 and the closed chamber through the first air intake hole 600, the second air intake hole 711 and the air passage 720, so that the air pressure in the closed chamber is connected with the outside, so as to release the connection between the suction cup 300 and the ground. Among them, the side wall of the piston 722 is slidably and tightly matched with the inner wall of the closed cavity. Specifically, the air intake cavity 700 and the piston 722 are both columnar, so that the piston 722 can only move up and down but not rotate, resulting in the airway 720 and the second air intake hole 711 being unable to correspond.

[0040] like Figure 7-11 As shown, in this embodiment, the top of the air inlet chamber 700 is connected with the retaining chamber 800, a frustum portion 730 is provided at the top of the piston 722, a first inclined surface is provided on the frustum portion 730, a locking block 1110 is provided on the second rack 330 through a connecting plate 840, a second inclined surface is provided on the locking block 1110 corresponding to the first inclined surface, and the locking block 1110 extends into the air inlet chamber 700 to drive the second inclined surface to squeeze the first inclined surface to realize the downward movement of the piston 722.

[0041] In this embodiment, when the second rack 330 moves, it can drive the locking block 1110 to move, and then the second inclined surface squeezes the first inclined surface, so that the conical portion 730 and the piston 722 move downward, and finally, the airway 720 corresponds to the second air inlet hole 711, and the outside air can enter the air inlet chamber 700 and the closed chamber. When the locking block 1110 moves in the opposite direction with the second rack 330, the second inclined surface separates from the first inclined surface. Under the thrust of the third spring 740, the piston 722 can move upward, so that the airway 720 and the second air inlet hole 711 are misaligned, thereby completing the closure of the air inlet chamber 700 and the closed chamber.

[0042] like Figure 1-5 As shown, in this embodiment, a cylindrical portion 101 is provided at the bottom wall of the base 100, a circular groove is provided at the bottom end of the cylindrical portion 101, a rotatable cylindrical rod 510 is provided in the circular groove, a plurality of arc grooves 503 are provided along the circumference of the outer wall of the cylindrical portion 101 corresponding to the support leg 110, a movable fan-shaped block 520 connected to the cylindrical rod 510 is provided in the arc groove 503, a fixing hole 213 is provided on the side wall of the support leg 110, and a locking rod 521 extending into the corresponding fixing hole 213 is provided on the fan-shaped block 520.

[0043] In this embodiment, when the legs 110 need to be fixed for storage, first, the legs 110 are rotated in sequence to bring the legs 110 close to the base 100, and then the cylindrical rod 510 is rotated to drive the fan-shaped block 520 to rotate accordingly. The locking rod 521 extends into the fixing hole 213, and the legs 110 are fixed by the locking rod 521. It is not easy to shake during transportation, and the space occupied by the legs 110 can be reduced.

[0044] like Figure 2-5As shown, in this embodiment, the first fan-shaped groove 501 and the second fan-shaped groove 502 are respectively provided at both ends of the arc groove 503, the fan-shaped block 520 can be inserted into the first fan-shaped groove 501 or the second fan-shaped groove 502, and the arc groove 503 is provided with a first elastic block for pushing the fan-shaped block 520 to be inserted into the first fan-shaped groove 501 or the second fan-shaped groove 502; the support leg 110 is provided with a sliding cavity 210 connected to the fixed cavity 400, and the side wall of the support leg 110 is provided with a strip groove 200 connected to the sliding cavity 210, and a slidable slider 211 is provided in the sliding cavity 210, and a fixing hole 213 is provided on the slider 211 at the strip groove 200.

[0045] In this embodiment, the first elastic block is located in the circular groove. Under the elastic force of the first elastic block, when the locking rod 521 extends into the corresponding fixing hole 213 and cooperates with the slider 211 to slide in the sliding cavity 210, the fan-shaped block 520 is preferably kept in the first fan-shaped groove 501 or the second fan-shaped groove 502, so that the fan-shaped block 520 will not move arbitrarily in the arc groove 503 during transportation. When the fan-shaped block 520 needs to be moved, a large force needs to be used to compress the first elastic block. At this time, it can The fan-shaped block 520 located in the first fan-shaped groove 501 is transferred into the second fan-shaped groove 502 through the arc groove 503. When the fan-shaped block 520 is located in the second fan-shaped groove 502, the locking rod 521 can be kept extended into the fixing hole 213. At this time, the leg 110 is fixed and will not shake. When the fan-shaped block 520 is located in the first fan-shaped groove 501, the locking rod 521 is disengaged from the fixing hole 213, and the fixation of the leg 110 can be released. At this time, the leg 110 can be unfolded to support the base 100.

[0046] like Figure 4-12 As shown, in this embodiment, the middle part of the movable plate 420 extends upward to form a sleeve 1210, a locking hole 1211 is provided at the side wall of the sleeve 1210, a second elastic block 1002 for pushing the slider 211 to move is provided at the bottom wall of the sliding cavity 210, and a locking rod 1001 is also provided on the slider 211, which passes through the second elastic block 1002 and extends into the locking hole 1211.

When the sector block 520 falls into the second sector groove 502, the locking rod 521 can drive the slider 211 to move in the sliding cavity 210, thereby making the locking rod 1001 extend into the locking hole 1211, so that the position of the sleeve 1210 is fixed, thereby fixing the position of the movable plate 420, preventing the movable plate 420 from accidentally moving down during transportation, causing the anti-slide plate 310 to rotate and unfold, and occupying a large space; The second elastic block 1002 is provided so that when the locking rod 521 moves from the second fan-shaped groove 502 to the arc-shaped groove 503, the slider 211 and the locking rod 1001 can move upward, so that the locking rod 1001 is separated from the locking hole 1211, and the fixing of the sleeve 1210 is released; Specifically, in order to install the second elastic block 1002 , a stopper is provided at the opening of the sliding cavity 210 close to the fixing cavity 400 .

[0048] like Figure 5 As shown, in this embodiment, the bottom end of the cylindrical rod 510 extends out of the circular groove, and a gripping plate 511 is provided at the protruding end of the cylindrical rod 510 .

[0049] In this embodiment, the holding plate 511 is provided to make it easier to hold the cylindrical rod 510 when rotating and moving it.

[0050] like Figure 4-12 As shown, in this embodiment, the top end of the rotating rod 410 passes through the supporting leg 111 and extends out, and a hand-cranked wheel 1201 is provided at the extended end of the rotating rod 410 .

[0051] In this embodiment, the top end of the sleeve 1210 is opened, and the rotating rod 410 is arranged through the sleeve 1210. Through the above structure, the rotation of the rotating rod 410 and the up and down movement of the sleeve 1210 can be carried out independently without interfering with each other. Among them, through the setting of the hand-cranked wheel 1201, the force point can be increased when the rotating rod 410 is rotated.

[0052] Working principle: When level detection is required, first, install the level on the base 100, then hold the cylindrical rod 510 and move it upward, so that the fan-shaped block 520 and the locking rod 521 move upward, drive the locking rod 1001 to disengage from the locking hole 1211, release the fixation of the sleeve 1210, rotate the cylindrical rod 510, drive the fan-shaped block 520 to rotate, so that the locking rod 521 disengages from the fixing hole 213, releases the fixation of the leg 110, and then rotate the leg 110 to make the leg 111 contact with the ground. During the downward movement of the leg 111, the suction cup 300 can increase the suction force between the leg 111 and the ground, and then rotate the rotating rod 41 0 drives the gear 831 to rotate, so that one end of the first rack 810 and the second rack 330 are separated from the locking hole. At this time, the movable frame 320 is moved downward to drive the hinged rod 311 to move downward, so that the anti-slip plate 310 is away from the support foot 111 and close to the ground, and the rotating rod 410 is released. Under the thrust of the second spring 842, one end of the first rack 810 and the second rack 330 can extend into the locking hole to fix the anti-slip plate 310 to prevent it from being separated from the ground under the thrust of the first spring 1101. Repeat the above operation until the anti-slip plates 310 on the three support feet 111 are in contact with the ground, thereby completing the installation of the base 100 on the ground.

[0053] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
