DETAILED DESCRIPTION

[0037] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0038] See attached Figure 1-10 As shown, the central axis tripod with a horizontal adjustment component in the utility model includes a central axis component 100 connected to a tripod 200. In order to facilitate finding the horizontal angle, a ball head bowl seat 300 is fixedly connected to the central axis component 200, and a ball head bowl 310 is provided in the ball head bowl seat 300. It also includes an upper cover 400 with a spirit level 410, which is connected to the top of the ball head bowl via a fastener 420.

[0039] In this embodiment, in order to perform horizontal adjustment and search, a deadlock push block 500 is provided in the ball head bowl seat 300, and the deadlock push block 500 is deadlocked with the deadlock ball bowl 320, and the deadlock ball bowl 320 forms a receiving cavity that fits with the ball head bowl 310; and then the deadlock push block can push the deadlock ball bowl 320 that is deadlocked with it, so that it pushes and drives the ball head bowl to move;

[0040] In order to facilitate the setting of movement space for the ball head bowl, a pressing block 600 is also included. An adjustment cavity is formed between the pressing block 600 and the ball head bowl seat 300. When the dead push block 500 is subjected to force and moves horizontally, it drives the dead ball bowl 320 to move in the adjustment cavity, making it close to the pressing block 600, and then the ball head bowl 310 is locked and fixed on the pressing block 600. When unlocking, the dead push block 500 acts in the opposite direction to move it to the right, and then the dead ball bowl 320 moves downward and to the right; in this embodiment, not only the movement adjustment of the ball head bowl is realized, but also the pressing block is used to fix it to prevent it from running around.

[0041] In this embodiment, refer to the attached Figure 1-4 As shown, in order to realize the force and action on the top dead push block 500, it also includes an adjusting member 510 which is threadedly connected with the ball head bowl seat 300 and passes through the ball head bowl seat to act on the top dead push block. The adjusting member 510 is provided with an undercut structure on the side close to the ball head bowl seat, and the top dead push block 500 is provided with a limiting groove 521 matching with it. Furthermore, in this embodiment, when in use, the adjusting member 510 acts on the top dead push block to make it push forward to the left to achieve locking and push the locking ball bowl 520 upward. When it is necessary to fall, the adjusting member 510 is used to move in the opposite direction, and then the undercut structure drives the limiting groove 521 to move synchronously to the right to complete unlocking, etc.

[0042] Specifically, in this embodiment, the side of the top-locking push block 500 extends upward to form a contact portion 520 that contacts the locking ball bowl 320, and then the limiting groove 521 is set on the contact portion 520, and the top-locking push block 500 also forms a top-locking push surface 530 that is closely attached to the locking ball bowl 320. The top-locking push surface 530 is added to provide a contact surface for the back push to drive the locking ball bowl 320 to move upward.

[0043] See attached Figure 5-6 As shown, the limiting groove 521 is located on the contact portion 520, and the limiting groove 521 forms an opening 522 smaller than the limiting groove 521 near the adjusting member 510. In this embodiment, the opening provides a certain gap for subsequent undercut pushing, etc. At the same time, during assembly, the adjusting member is directly placed in the limiting groove, and then a part is located in the limiting groove and a part is located at the opening.

[0044] Specifically, the adjusting member 510 includes a knob 511 and a threaded rod 512, and the undercut structure of the threaded rod 512 near the contact portion 520 includes a base 513 formed by extending the threaded rod 512 and matching the opening 522, and a locking portion 514 extending from the end of the base 513 toward the periphery and located in the limiting groove 521. In use, the knob drives the threaded rod to move, thereby pushing the contact portion 520 on the top dead push block to move to the left, and in the reverse movement, at this time, due to the undercut relationship between the contact portion and the adjusting member, the screw rod moves to the right, naturally driving the top dead push block 500 to move rightward, providing a basic condition for retreat.

[0045] Referring to the accompanying drawings, it can be seen that in this embodiment, in order to facilitate contact with the arc at the bottom of the ball head bowl and hold it, in this embodiment, the locking ball bowl 320 includes a body with a central hole, and the body extends outward to form an abutment portion 321 that abuts against the ball head bowl 310. To further match it, the cross section of the abutment portion 321 is an expanded structure with a gradually increasing width from the inside to the outside, and the lower surface of the expanded structure is an assembly inclined surface that matches the inclined surface of the contact portion 520 in the dead push block 500.

[0046] In this embodiment, the top dead pushing block 500 is close to the driving mechanism 510 and extends upward to form a contact portion 520 that contacts one side of the locking ball bowl, and the top dead pushing block 500 is formed with a top pushing surface 530 that is in close contact with the other side of the locking ball bowl 320. Specifically, the top pushing surface 530 forms an upward inclined surface, while the contact portion 520 is a downward inclined surface.

[0047] When the ball head bowl seat 300 and the clamping block 600 are assembled, the fastening screw 610 passing through the bottom of the clamping block 600 is inserted into the sleeve rod 330 formed upward at the center of the ball head bowl seat 300 to complete the assembly of the two. Then, during the up and down movement, since it is a sleeve connection, there is a certain space, which is convenient for up, down, left and right movement.

[0048] When other components are assembled, from top to bottom, the ball head bowl 310, the locking ball bowl 320 and the top push block 500 are all sleeved on the sleeve rod 330. Then the entire movement is a movement around the sleeve rod 330.

[0049] Under the action of the driving mechanism 510, the ball head bowl 310 moves horizontally along the sleeve rod 330, and the deadlock assembly 500 is under force, and the deadlock ball bowl 310 and the deadlock push block 500 drive the ball head bowl 310 to form a 20° universal adjustment range in the ball head bowl seat 300. At this time, a universal adjustment range is formed that floats up and down at 20° and can rotate 360° horizontally.

[0050] The bottom of the ball head bowl seat 300 extends downward to form an assembly portion 340 with external threads, and the inner wall of the top of the middle shaft assembly 100 is provided with threads matching therewith, so that the two can be assembled directly through threaded connection.

[0051] See attached Figure 5-7 As shown, in this embodiment, the tripod 200 further includes a tripod seat 210 for the central axis assembly 100 to pass through, and the three leg tubes 220 are hinged to the tripod seat 210 through leg tube joints 230. In this embodiment, the tripod can be directly opened and closed by hinge connection.

[0052] In order to facilitate lifting and lowering and realize the use at different heights, the central axis assembly 100 is connected to a lifting mechanism that drives it to rise and fall along the tripod seat 210, and the leg tube joints 220 are all telescopic tubes. Then the length of the tripod can be adjusted according to the telescopic tubes.

[0053] The central axis tripod in the utility model generally has the following main components:

[0054] 1) The tripod is mainly composed of a tripod base 210, a leg tube 220, etc. The tripod base 210 is assembled with a leg tube joint 230 so that the leg tube joint can rotate along the axis; the leg tube joint 230 is fixed to the leg tube 220 so that the angle of the leg tube can be adjusted; a positioning cavity is formed in the middle of the tripod base 210, and the middle axis assembly 100 is located in the positioning cavity, and then a leg tube that can be freely extended and retracted is selected to perform free extension and retraction;

Then the ball head bowl 310 automatically moves between the locking ball bowl 320 and the pressing block 600; the pressing block 600 and the ball head bowl seat 300 are fixed as a whole by the center fastening screw; the locking ball bowl 320 can only move up and down in the ball head bowl seat 300, the upper arc is tightly attached to the ball head bowl 310, and the lower inclined surface is tightly attached to the inclined surface of the top dead push block 500, so that when the top dead push block moves to the left, the locking ball bowl can move upward, so that the distance between the pressing block and the locking ball wrist becomes smaller, thereby locking the ball bowl; the top dead push block in this embodiment can only move left and right in the ball head bowl seat, and there is an inclined surface of the top dead push block on it to match the inclined surface of the locking ball bowl;

[0057] In order to facilitate the control of the top dead push block, the driving mechanism in this embodiment is a screw assembly, which is arranged along the horizontal direction of the ball head bowl seat and then threadedly connected with the ball head bowl seat. When the knob is rotated, the knob moves to the left, which pushes the top dead push block, so that the distance between the clamping block and the locking ball wrist becomes smaller, thereby locking the ball bowl;

[0058] 4) The upper cover is fixed to the ball head bowl seat by four small screws; a level 410 is assembled on its side, and then a 1 / 4 screw is set on the upper cover: it is mainly grafted with the camera and fixedly connected to the upper cover.

[0059] The utility model utilizes a top-lock push block, which is convenient for assembly and horizontal adjustment.
