[0001] The present invention relates to the field of table clamp accessories, and more specifically to table clamps. Background Technology

[0003] Conventional table clamps are practical and versatile table aids primarily used to secure items to be placed on brackets or tables. Typically composed of a clamping part and a stable base, they are clamped to the edge of the table or secured to the table in other ways.

[0004] The clamping portion of a conventional table clamp is typically clamped to the edge of the table by compressing it with a rotating knob, thereby securing the table clamp. During this process, the contact surfaces between the clamping portion and the upper and lower sides of the table are typically in direct contact and compressed. However, during the compression process by rotating the knob, the contact surfaces between the table clamp and the upper and lower sides of the table rotate along the knob, causing relative positional shifts; consequently, damage to the table and destruction of the table surface frequently occur;

[0028] Hereinafter, with reference to the drawings according to the embodiments of the present invention, a technical solution according to the embodiments of the present invention will be clearly and completely explained. However, the embodiments described below are merely partial embodiments of the present invention and do not represent all embodiments. All other embodiments obtained by those skilled in the art without creative labor based on the embodiments of the present invention are included within the scope of protection sought by the present invention.

[0029] First embodiment

[0030] As illustrated in FIGS. 1 to 10, the present embodiment is for providing a table clamp, wherein the table clamp comprises at least one clamp body (1) for being fixedly clamped to the edge side of a table board, at least one lifting platform (2) for compressing one side of the table board, at least one guide rod (3) for moving up and down in combination with the lifting platform (2), and at least one knob (4) for adjusting the up and down of the lifting platform (2) through rotation;

[0031] The clamp body (1) is a fixed block structure, and a first groove (101) is formed in a recess on one side of the clamp body (1), and the first groove (101) is positioned on the edge side of the table board, and by fixing the edge side of the table board within the first groove (101), the clamp body (1) can be fixedly installed on the table board;

[0032] The inner surface of the first groove (101) is divided into a first side (102) and a second side (103), the first side (102) is in pressurized contact with the upper side of the edge of the table board, and the second side (103) has a first through hole (104) for allowing movement of the lifting platform (2) and a second through hole (105) for allowing movement of the guide rod (3) formed through downwards;

[0033] The above lifting platform (2) is configured to include at least one limiting block (201) and at least one lifting section, one side of the limiting block (201) is installed opposite to the first side (102), and the other side is fixedly connected to the lifting section, and the guide rod (3) is fixedly connected to the side of the limiting block (201) facing the lifting section;

[0034] A first screw hole (2011) is formed in a recess on one side of the limiting block (201) opposite to the first side (102), and the guide rod (3) has a thin and long rod-shaped structure, and a first external screw thread (301) is formed on the outer surface of one end of the guide rod (3), and the first external screw thread (301) and the first screw hole (2011) are matched with each other to fixably connect the limiting block (201) to the guide rod (3);

[0035] The lifting unit is installed within the first through hole (104), and the guide rod (3) is positioned within the second through hole (105). The first through hole (104) and the second through hole (105) have through hole structures at different centrifugal positions. The guide rod (3) moves synchronously according to the movement of the limiting block (201). The movement method of the lifting unit is a screw and sleeve drive method. Specifically,

[0036] The lifting unit is configured to include at least one first screw (202) and at least one first sleeve (203), a second screw hole (2012) is formed in a recess on one side of the limiting block (201), and a first screw external thread (2021) is formed on the outer side of the first screw (202). One end of the first screw (202) is fixedly connected to the limiting block (201), and the fixed connection method is such that the second screw hole (2012) and the first screw external thread (2021) are fixedly connected by rotating and tightening.

[0037] The first sleeve (203) is a sleeve structure with one side formed in a recess, and the inner wall of the first sleeve (203) has a first sleeve internal thread (2031) formed therein, and the first sleeve (203) engages with the first screw (202) to move the first screw (202) up and down within the first sleeve (203), and the first sleeve (203) is installed within the first through hole (104), and the knob (4) is fixedly connected to one side of the first sleeve (203) opposite to the limiting block (201);

[0038] Specifically, a third screw hole (2032) is formed on one side of the first sleeve (203) opposite to the limiting block (201), and a third through hole (401) is formed at a position corresponding to the third screw hole (2032) in the knob (4), and the third through hole (401) is a through hole structure having a step, and a bolt is coupled at the position of the third through hole (401), and the bolt penetrates the third through hole (401) and is fixedly connected to the third screw hole (2032) to fixly connect the knob (4) and the first sleeve (203);

[0039] A first limiting groove (2033) is formed in a recess on the outer wall of the first sleeve (203), and after the first sleeve (203) is inserted into the first through hole (104), a fourth screw hole (106) is formed through the first limiting groove (2033) position corresponding to the side of the clamp body (1), and a positioning screw (107) for limiting the first sleeve (203) is formed in the fourth screw hole (106), and the positioning screw (107) is rotatably inserted into the internal space of the first through hole (104) through the fourth screw hole (106), and one end of the positioning screw (107) is installed within the first limiting groove (2033) so that the first sleeve (203) is limited and moves within the first through hole (104), thereby the first The sleeve (203) can rotate within the first through hole (104) but cannot move up and down, and when the first sleeve (203) rotates, it itself cannot move up and down within the first through hole (104), but drives the first screw (203) to move up and down.

[0040] The side area of ​​the knob (4) is larger than the open area of ​​the first through hole (104), and the side area of ​​the limiting block (201) is larger than the open area of ​​the first through hole (104); the first sleeve (203) is inserted into the first groove (101) from the first through hole (104) and is fixedly connected to the limiting block (201); and the guide rod (3) is inserted into the first groove (101) from the second through hole (105) and is fixedly connected to the limiting block (201);

[0041] One end of the first sleeve (203) opposite to the limiting block (201) is fixedly connected to the knob (4), and the first sleeve (203) and the first screw (202) are rotatably connected to the external thread (2021) of the first screw through the internal thread (2031) of the first sleeve.

[0042] Furthermore, at least one silicone protective layer (5) is formed on each of the first side (102) and the limiting block (201) that contacts the upper and lower sides of the table board;

[0043] When using the table clamp, the first groove (101) is installed by hooking it onto the edge side of the table board, and when the user rotates the knob (4), the first sleeve (203) rotates within the first through hole (104). Since the first sleeve (203) moves while being limited, the first sleeve (203) transmits electric power to the first screw (202). Since the first screw (202) is subject to the limiting action of the guide rod (3), the first screw (202) cannot rotate. Therefore, it can only move according to the helical drive principle. Since helical drive is a mechanical drive method that achieves a drive effect by converting rotational movement into linear movement using the interaction between the first screw (202) and the first sleeve (203), the limiting block (201) can be moved up and down within the first groove (101).

[0044] The limiting block (201) is pressed parallel to the lower side of the table board, and the first side (102) is pressed parallel to the upper side of the table board. During the process of pressing the table board, no frictional force of surface rotation occurs between the first side (102), the limiting block (201), and the upper and lower sides of the table board. Therefore, the table board is protected from scratching, and the silicone protective layer (5) does not shift position or detach from the table board. By allowing the table board to be pressed by the first side (102) and the limiting block (201), the table board and the table clamp can be fixed and limited. As a very practical table aid with a simple overall operation process, it is particularly suitable for situations where the table must be used for a long time, such as for learning or creative work, by providing an extension function for the table board outdoors.

[0045] Furthermore, as illustrated in FIGS. 6 to 9, a fifth screw hole (108) is formed on the upper side of the clamp body (1), and through the fifth screw hole (108), various extension brackets, such as a vertical rod bracket (6) on which a basket can be hung, can be fixedly and rotatably connected. One end of the vertical rod bracket (6) and the fifth screw hole (108) are fixed through a bolt connection. The method of fixing the fifth screw hole (108) and the vertical rod bracket (6) is a conventional method in this field and is not specifically limited thereto.

[0046] A position fixing groove (601) is formed in the outer circumference groove of the vertical rod bracket (6), and the position fixing groove (601) has a ring-shaped groove structure, and at least one first elastic buckle structure (602) is installed on the position fixing groove (601);

[0047] The first elastic buckle structure (602) is configured to include an upper case (603), a lower case (604), a first buckle block (605), a spring, and a first pressing block (606). The upper case (603) and the lower case (604) are combined with each other, and the first buckle block (605), the spring, and the first pressing block (606) are embedded therein. Specifically, a first through hole (607) is formed through one side of the upper case (603), and a second through hole (608) is formed through one side of the lower case (604). The vertical rod bracket is inserted and installed in the first through hole (607) and the second through hole (608).

[0048] A first positioning column (609) is extended from one side of the lower case (604), and a rotation hole (610) is formed through the first buckle block (605) to correspond to the first positioning column (609), the rotation hole (610) is installed on the first positioning column (609), and the first buckle block (605) moves around the first positioning column (609);

[0049] Two first buckle blocks (605) are formed on the side of the first through hole (607), and a limiting projection (611) is connected from one side of the first buckle block (605) facing the first through hole (607), and the limiting projection (611) is engaged with the position fixing groove (601) to perform a limiting function. A spring and a first pressing block (606) are installed on one side of the first buckle block (605) opposite to the limiting projection (611), and a third through hole (612) is formed through the upper case (603) corresponding to the first pressing block (606), and one end of the first pressing block (606) protrudes from the third through hole (612).

[0050] When the first elastic buckle structure (602) is installed on the vertical rod bracket, the limiting projection (611) is compressed in the direction of the vertical rod bracket under the force of the spring. Therefore, when the first elastic buckle moves to the position fixing groove (601), the limiting projection is locked and fixed with the position fixing groove (601), thereby fixing the first elastic buckle structure (602) onto the vertical rod bracket.

[0051] Through the two table clamps, the two vertical rod brackets (6), and the plurality of first elastic buckle structures (602), a basket (7) can be hung on the two vertical rod brackets (6), and by hanging the basket above the first elastic buckle structure (602), the extension function of the table clamp can be used, thereby expanding the method of use of the table clamp.

[0052] Furthermore, as illustrated in FIGS. 10 to 13, a second elastic buckle structure (8) is formed on the rear side of the table body (1), and the second elastic buckle structure (8) can securely hold an extension bracket, such as a horizontal rod (9) on which an object can be hung. One end of the horizontal rod (9) is secured to the elastic buckle structure (8), and through the two table clamps and the horizontal rod (9), an object can be hung on the horizontal rod (9).

[0053] Specifically, the second elastic buckle structure (8) comprises a second pressing block (801), a spring, a moving block (802), and a lower limiting block (803); a first moving groove (804) is formed through the rear side of the clamp body (1); a first limiting step (805) is formed on the inner circumference of the first moving groove (804) to be installed to limit the spring; a second positioning column (806) is formed in conjunction with the lower part of the second pressing block (801); the spring is installed on the second positioning column (806); and the second positioning column (806) and the moving block (802) are fixedly connected through a bolt;

[0054] A first limiting through hole (807) is formed through the rear side of the clamp body (1), a second limiting through hole (808) is formed through the center position of the movable block (802), a second buckle block (809) is formed extending from the inside of the second limiting through hole (808), a lower limiting block (803) is fixedly connected to the lower part of the movable block (802), a second limiting step (810) is formed extending on the inner circumference side of the first movable groove (804) to correspond to the lower limiting block (803), and the lower limiting block (803) is in contact with the second limiting step (810);

[0055] As the above spring comes into contact with the first limiting step (805) and presses the second pressing block (801), the moving block (802) moves downward, so the spring provides an upward elastic force to the moving block (802), and as the lower limiting block (803) comes into contact with the second limiting step (810), the moving block (802) is made to move only within the first moving groove (804).

[0056] The above-mentioned moving block (802) moves by being positioned in the first moving groove (804), and the horizontal rod (9) has a buckle groove (901) formed in a recess corresponding to the second buckle block (809). When the first limiting through hole (807) and the second limiting through hole (808) are aligned, the horizontal rod (9) can be inserted into the second limiting through hole (808), and the buckle groove (901) is engaged with the second buckle block (809), providing an upward elastic force to the moving block (802) by means of the spring. Accordingly, the horizontal rod (9) and the table clamp can be fixedly connected. When removing the horizontal rod (9), simply pressing the second pressing block (801) causes the second buckle block (809) to move downward, and the buckle groove (901) and the second buckle block (809) to separate from each other, thereby allowing the horizontal rod (9) and the table clamp to be disassembled. Since the entire operation process is simple and the extension function of the table clamp can be used, the method of using the table clamp can be expanded.

[0057] 2nd embodiment

[0058] As illustrated in FIGS. 14 to 17, the second embodiment is largely identical to the first embodiment, but the distinguishing feature is that the lifting member moves up and down within the first through hole (104) as follows. That is, the lifting member is configured to include at least one second sleeve (204) and at least one second screw (205), and one side of the limiting block (201) opposite to the first side (102) is fixedly connected to the second sleeve (204), the second sleeve (204) is a sleeve structure with one side formed as a recess, and a second sleeve internal thread (2041) is formed on the inner wall of the second sleeve (204);

[0059] The guide rod (3) is fixedly connected to one side of the limiting block (201) facing the lifting unit; the second sleeve (204) is installed within the first through hole (104), and the guide rod (3) is positioned within the second through hole (105), and the first through hole (104) and the second through hole (105) have through hole structures at different centrifugal positions, and the guide rod (3) moves synchronously according to the movement of the limiting block (201), and the movement method of the lifting unit is a drive method of a screw and a sleeve, specifically,

[0060] The knob (4) is fixedly connected to one side of the second screw (205) opposite to the limiting block (201), specifically, a sixth screw hole (2051) is formed on one side of the second screw (205) opposite to the limiting block (201), and a fourth through hole (402) is formed at a position corresponding to the sixth screw hole (2051) of the knob (4), the fourth through hole (402) is a through hole structure with a step, and a bolt is coupled to the position of the fourth through hole (402), and the bolt penetrates the fourth through hole (402) and is fixedly connected to the sixth screw hole (2051), thereby fixing the knob (4) and the second screw (205);

[0061] A second limiting groove (2052) is formed in a recess on the outer wall of the second screw (205), and after the second screw (205) is inserted into the first through hole (104), a seventh screw hole (109) is formed through the position of the second limiting groove (2052) corresponding to the side of the clamp body (1), and a positioning screw (107) for limiting the second screw (205) is formed in the seventh screw hole (109), and the positioning screw (107) is rotatably inserted into the internal space of the first through hole (104) through the seventh screw hole (109), and one end of the positioning screw (107) is installed within the second limiting groove (2052) so that the second screw (205) is limited and moves within the first through hole (104), thereby the second The screw (205) can rotate within the first through hole (104) but cannot move up and down;

[0062] A third limiting groove (2042) is formed through a position corresponding to the positioning screw (107) on the outer side of the second sleeve (204), and the third limiting groove (2042) is a strip-shaped groove formed by being recessed from the opening surface of the second sleeve (204). When the second sleeve (204) moves up and down within the first groove (101), the positioning screw (107) is located only within the strip-shaped groove and does not affect the up and down movement of the second sleeve (204). Due to the positioning screw (107), when the second screw (205) rotates, it itself cannot move up and down within the first through hole (104), but drives the second sleeve (204) to move up and down.

[0063] On the outer side of the second screw (205), a second screw external thread (2053) is formed, and the second sleeve internal thread (2041) and the second screw external thread (2053) are matched with each other, and the second sleeve (204) engages with the second screw (205);

[0064] When the user rotates the knob (4), the second screw (205) rotates, and the second sleeve (204) moves up and down along the second screw (205), thereby causing the limiting block (201) to move up and down within the first groove (101).

[0065] When using the table clamp, the inside of the first groove (101) is installed by hooking it onto the edge side of the table board, and when the user rotates the knob (4), the second screw (205) rotates within the first through hole (104). Since the second screw (205) moves while being limited, the second screw (205) transmits electric power to the second sleeve (204). Since the second sleeve (204) is subject to the limiting action of the guide rod (3), the second sleeve (204) cannot rotate. Therefore, it can only move according to the spiral drive principle. Since spiral drive is a mechanical drive method that achieves an electric drive effect by converting rotational movement into linear movement using the interaction between the second sleeve (204) and the second screw (205), the limiting block (201) can be moved up and down within the first groove (101).

[0066] The limiting block (201) is pressed parallel to the lower side of the table board, and the first side (102) is pressed parallel to the upper side of the table board. During the process of pressing the table board, no frictional force of surface rotation occurs between the first side (102), the limiting block (201), and the upper and lower sides of the table board. Therefore, the table board is protected from scratching, and the silicone protective layer (5) does not shift position or detach from the table board. By allowing the table board to be pressed by the first side (102) and the limiting block (201), the table board and the table clamp can be fixed and limited. As a very practical table aid with a simple overall operation process, it is particularly suitable for situations where the table must be used for a long time, such as for learning or creative work, by providing an extension function for the table board outdoors.
