Description

Technical Field

[0001] The utility model relates to the technical field of desktop clamp accessories, in particular to a desktop clamp. Background Art

[0002] The existing desktop clamp is a practical and multifunctional desktop auxiliary tool, which is mainly used to fix a bracket or something to be placed on the desktop on the desktop. It usually has a clamping part and a stable base, which can be conveniently clamped on the side of the desktop or fixed on the desktop by other means.

[0003] The clamping part of the current desktop clamp usually uses a knob to tighten the side of the desktop to fix the desktop clamp. In this process, the general clamping part directly contacts and presses the contact surface of the upper and lower sides of the desktop. When the knob is tightened, the contact surface of the desktop clamp and the upper and lower sides of the desktop rotates with the knob, and a relative displacement occurs, which often damages the desktop and destroys the surface craftsmanship of the desktop.

[0004] Furthermore, the contact surface between the clamping part and the upper side of the desktop is generally provided with a protective silicone layer, and the contact surface between the clamping part and the lower side of the desktop is provided with a protective silicone layer. During the process of tightening the knob, the silicone layer in contact with the upper and lower sides of the desktop rotates with the knob, which often causes the protective silicone to shift and debond, resulting in a very bad user experience. Currently, there is no product on the market that can solve this problem. Utility Model Content

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] First embodiment

[0041] like Figure 1-10 As shown, this embodiment provides a desktop clamp, which includes at least one clamp body 1 for fixing and clamping on the side of the desktop board, at least one lifting platform 2 for pressing the lower side of the desktop board, at least one guide rod 3 for cooperating with the lifting platform 2 to move up and down, and at least one knob 4 for adjusting the lifting platform 2 up and down by rotating;

[0042] The table clamp body 1 is a fixed block structure, and one side of the table clamp body 1 is recessed to form a first groove 101, and the first groove 101 is placed on the side of the desktop board. By fixing the side of the desktop board in the first groove 101, the table clamp body 1 and the desktop board are fixedly arranged;

[0043] The inner side surface of the first groove 101 is defined as a first side surface 102 and a second side surface 103. The first side surface 102 and the upper side surface of the edge of the desktop are pressed and contacted with each other. The second side surface 103 is downwardly penetrated to form a first through hole 104 for allowing the lifting platform 2 to move, and a second through hole 105 for allowing the guide rod 3 to move.

[0044] The lifting platform 2 includes at least one limit block 201 and at least one lifting part. One side of the limit block 201 is arranged opposite to the first side 102, and the other side is fixedly connected to the lifting part. The guide rod 3 is fixedly connected to the side of the limit block 201 facing the lifting part.

[0045] The stop block 201 is recessed on one side opposite to the first side surface 102 to form a first threaded hole 2011. The guide rod 3 is an elongated rod-shaped structure. A first external thread 301 is provided on the outer side surface of one end of the guide rod 3. The first external thread 301 and the first threaded hole 2011 are adapted to each other to achieve a fixed connection between the stop block 201 and the guide rod 3.

[0046] The lifting part is arranged in the first through hole 104, and the guide rod 3 is arranged in the second through hole 105. The first through hole 104 and the second through hole 105 are through hole structures at different circle center positions. The guide rod 3 moves synchronously with the movement of the limit block 201. The movement mode of the lifting part is through the transmission mode of the screw and the sleeve, which is specifically:

[0047] The lifting part includes at least one first screw rod 202 and at least one first sleeve 203. One side of the limit block 201 is recessed to form a second threaded hole 2012. The outer side of the first screw rod 202 is provided with a first screw external thread 2021. One end of the first screw rod 202 is fixedly connected to the limit block 201. The fixed connection method includes tightening and fixing the second threaded hole 2012 with the first screw external thread 2021.

[0048] The first sleeve 203 is a sleeve structure formed by a side depression. A first sleeve internal thread 2031 is provided on the inner side wall of the first sleeve 203. The first sleeve internal thread 2031 and the first screw external thread 2021 are adapted to each other. The first sleeve 203 and the first screw 202 are meshed and driven to realize the lifting and lowering movement of the first screw 202 in the first sleeve 203. The first sleeve 203 is provided in the first through hole 104, and the first sleeve 203 is fixedly connected to the knob 4 on a side opposite to the limit block 201.

[0049] Specifically, a third threaded hole 2032 is provided on a side of the first sleeve 203 opposite to the limit block 201, and a third through hole 401 is provided at a position of the knob 4 corresponding to the third threaded hole 2032. The third through hole 401 is a through hole structure with a step, and a screw is provided at the third through hole 401. The screw passes through the third through hole 401 and is fixedly screwed with the third threaded hole 2032, so as to realize a fixed connection between the knob 4 and the first sleeve 203;

[0050] The outer wall of the first sleeve 203 is recessed to form a first limiting groove 2033. After the first sleeve 203 is extended into the first through hole 104, a fourth threaded hole 106 is penetrated and opened on the side of the table clamp body 1 corresponding to the position of the first limiting groove 2033. The fourth threaded hole 106 is provided with a positioning screw 107 for limiting the first sleeve 203. The positioning screw 107 is screwed into the inner space of the first through hole 104 through the fourth threaded hole 106, and one end of the positioning screw 107 is arranged in the first limiting groove 2033, so that the first sleeve 203 can be limited in the first through hole 104, so that the first sleeve 203 can be rotated in the first through hole 104, but cannot be lifted or lowered. When the first sleeve 203 rotates, it cannot be lifted or lowered in the first through hole 104 by itself, and can only drive the first screw rod 202 to be lifted or lowered.

[0051] The side area of ​​the knob 4 is larger than the opening area of ​​the first through hole 104, the side area of ​​the limit block 201 is larger than the opening area of ​​the first through hole 104, the first sleeve 203 extends from the first through hole 104 into the first groove 101 and is fixedly connected to the limit block 201, the guide rod 3 extends from the second through hole 105 into the first groove 101 and is fixedly connected to the limit block 201;

[0052] An end surface of the first sleeve 203 opposite to the limit block 201 is fixedly connected to the knob 4 , and the first sleeve 203 and the first screw rod 202 are screwed together via the first sleeve internal thread 2031 and the first screw rod external thread 2021 .

[0053] Furthermore, at least one silicone protective layer 5 is provided on the first side surface 102 and the side surface of the limiting block 201 that contacts the upper and lower side surfaces of the desktop panel respectively;

[0054] When the desktop clamp is used and is clamped on the side of the desktop panel inside the first groove 101, the user rotates the knob 4 to realize the rotation of the first sleeve 203 in the first through hole 104. Due to the limiting activity of the first sleeve 203, the first sleeve 203 transmits the transmission force to the first screw 202. Under the limiting action of the guide rod 3, the first screw 202 cannot rotate on its own, so it can only move according to the spiral transmission principle. The spiral transmission is a mechanical transmission method that utilizes the interaction between the first screw 202 and the first sleeve 203 to convert the rotational motion into linear motion to achieve the transmission effect, thereby realizing the lifting and lowering movement of the limit block 201 in the first groove 101.

[0055] The limiting block 201 is pressed flush against the lower side of the desktop panel, and the first side 102 is pressed flush against the upper side of the desktop panel. In the process of pressing the desktop panel, since there is no surface rotation friction between the first side 102, the limiting block 201 and the upper and lower sides of the desktop panel, the desktop panel is protected from scratches, and the silicone protective layer 5 will not shift or debond with the desktop panel. After the desktop panel is pressed by the first side 102 and the limiting block 201, the desktop panel and the desktop clamp are fixedly limited. The whole operation process is simple, and the desktop is a very practical desktop auxiliary tool, especially suitable for outdoor desktop panel expansion functions, learning or creation, and other scenes that require long-term use of desktop panel expansion.

[0056] Furthermore, if Figure 6-9As shown, a fifth threaded hole 108 is provided on the top side of the table clamp body 1, and various extension brackets can be fixed and screwed through the fifth threaded hole 108, such as a vertical rod bracket 6 for hanging a basket, and one end of the vertical rod bracket 6 is fixed to the fifth threaded hole 108 by screwing. The fixed connection method of the fifth threaded hole 108 and the vertical rod bracket 6 is a conventional method in the field and is not specifically limited here.

[0057] A locking groove 601 is formed in the outer peripheral groove of the vertical rod bracket 6. The locking groove 601 is a circular groove structure. At least one first elastic buckle structure 602 is sleeved and locked on the locking groove 601.

[0058] The first elastic buckle structure 602 includes an upper shell 603, a lower shell 604, a first buckle block 605, a spring, and a first push block 606. The upper shell 603 is combined with the lower shell 604, and the first buckle block 605, the spring, and the first push block 606 are built in. Specifically, a first through hole 607 is formed through a side surface of the upper shell 603, and a second through hole 608 is formed through a side surface of the lower shell 604. The vertical rod bracket can be sleeved into the first through hole 607 and the second through hole 608.

[0059] A first positioning column 609 extends from one side of the lower housing 604, and a rotation hole 610 is formed through the first buckle block 605 corresponding to the first positioning column 609. The rotation hole 610 is sleeved on the first positioning column 609, and the first buckle block 605 moves around the first positioning column 609;

[0060] The two first buckle blocks 605 are arranged beside the first through hole 607, and the first buckle block 605 extends a limiting protrusion 611 toward one side of the first through hole 607, and the limiting protrusion 611 can be mutually engaged and limited with the locking groove 601. The spring and the first push block 606 are arranged on the side of the first buckle block 605 opposite to the limiting protrusion 611, and the upper shell 603 is provided with a third through hole 612 corresponding to the first push block 606, and one end side of the first push block 606 extends out of the third through hole 612.

[0061] The first elastic buckle structure 602 is sleeved on the vertical pole bracket. Since the limiting protrusion 611 is pressed toward the vertical pole bracket under the action of the spring, when the first elastic buckle moves to the locking groove 601, the limiting protrusion 611 and the locking groove 601 are locked with each other, so that the first elastic buckle structure 602 is fixed to the vertical pole bracket.

[0062] By means of the two desktop clamps, the two vertical pole brackets 6, and the plurality of the first elastic buckle structures 602, it is possible to hang a storage basket 7 on the two vertical pole brackets 6, and the storage basket is hung above the first elastic buckle structure 602, thereby realizing the use of the extended function of the desktop clamp and greatly enriching the use scenarios of the desktop clamp.

[0063] Furthermore, if Figure 10-13 As shown, a second elastic snap-in structure 8 is provided on the back side of the table clamp body 1, and the second elastic snap-in structure 8 is snap-connected and fixed to an extended bracket, such as a horizontal cross bar 9 for hanging things. One end of the horizontal cross bar 9 is snap-connected and fixed to the elastic snap-in structure 8, and things can be hung on the horizontal cross bar 9 through the two table clamps and the horizontal cross bar 9.

[0064] Specifically, the second elastic buckle structure 8 includes a second push block 801, a spring, a movable block 802, and a lower limit block 803. A first movable groove 804 is formed on the back side of the table clamp body 1. The inner circumference of the first movable groove 804 forms a first limit step 805 for limiting the position with the spring. A second positioning column 806 extends below the second push block 801. The spring is sleeved on the second positioning column 806, and the second positioning column 806 is fixedly connected to the movable block 802 by bolts.

[0065] A first limiting through hole 807 is formed through the back side of the table clamp body 1, a second limiting through hole 808 is formed through the center of the movable block 802, a second buckle block 809 extends from the inner side of the second limiting through hole 808, and the lower limiting block 803 is fixedly connected to the lower side of the movable block 802, a second limiting step 810 extends from the inner circumference of the first movable groove 804 corresponding to the lower limiting block 803, and the lower limiting block 803 and the second limiting step 810 abut against each other;

[0066] Since the spring abuts against the first limit step 805, and the movable block 802 moves downward when the second push block 801 is pressed downward, the spring provides an upward rebound force for the movable block 802, and the lower limit block 803 abuts against the second limit step 810, so that the movable block 802 can only move in the first movable groove 804.

[0067] The movable block 802 is located in the first movable groove 804 and moves. The horizontal cross bar 9 is recessed to form a snap groove 901 corresponding to the second snap block 809. When the first limiting through hole 807 is aligned with the second limiting through hole 808, the horizontal cross bar 9 can be inserted into the second limiting through hole 808. The snap groove 901 and the second snap block 809 are mutually engaged. The spring provides an upward rebound force for the movable block 802. The horizontal cross bar 9 is fixedly connected to the desktop clamp. When the horizontal cross bar 9 needs to be removed, it is only necessary to press the second push block 801, the second snap block 809 moves downward, and the snap groove 901 and the second snap block 809 are separated from each other, so that the horizontal cross bar 9 and the desktop clamp can be separated. The whole process is simple to operate, and the extended function of the desktop clamp can be used, which greatly enriches the usage scenarios of the desktop clamp.

[0068] Second embodiment

[0069] like Figure 14-17 As shown, the second embodiment is mostly the same as the above embodiment, except that the lifting movement of the lifting part in the first through hole 104 is replaced by the lifting part including at least one second sleeve 204 and at least one second screw 205, the stop block 201 is fixedly connected to the second sleeve 204 on the side opposite to the first side 102, the second sleeve 204 is a sleeve structure formed by a side depression, and the inner side wall of the second sleeve 204 is provided with a second sleeve internal thread 2041;

[0070] The guide rod 3 is fixedly connected to a side of the limit block 201 facing the lifting part; the second sleeve 204 is disposed in the first through hole 104, and the guide rod 3 is disposed in the second through hole 105. The first through hole 104 and the second through hole 105 are through hole structures at different center positions. The guide rod 3 moves synchronously with the movement of the limit block 201. The lifting part moves in a transmission mode through a screw and a sleeve, specifically:

[0071] The second screw rod 205 is fixedly connected to the knob 4 at a side opposite to the limit block 201. Specifically, a sixth threaded hole 2051 is provided on a side of the second screw rod 205 opposite to the limit block 201, and a fourth through hole 402 is provided at a position of the knob 4 corresponding to the sixth threaded hole 2051. The fourth through hole 402 is a through hole structure with a step, and a screw is provided at the fourth through hole 402. The screw passes through the fourth through hole 402 and is fixedly screwed with the sixth threaded hole 2051, so as to realize the fixed connection between the knob 4 and the second screw rod 205.

[0072] The outer wall of the second screw rod 205 is recessed to form a second limiting groove 2052. After the second screw rod 205 is inserted into the first through hole 104, a seventh threaded hole 109 is formed through the side surface of the table clamp body 1 at a position corresponding to the second limiting groove 2052. A positioning screw 107 for limiting the second screw rod 205 is provided in the seventh threaded hole 109. The positioning screw 107 is screwed into the inner space of the first through hole 104 through the seventh threaded hole 109, and one end of the positioning screw 107 is arranged in the second limiting groove 2052, so that the second screw rod 205 can be limited in the first through hole 104, so that the second screw rod 205 can rotate in the first through hole 104, but cannot be lifted or lowered.

[0073] The outer circumference of the second sleeve 204 corresponds to the position of the positioning screw 107, and is penetrated by a third limiting groove 2042, which is a strip groove formed by being sunken from the opening surface of the second sleeve 204. When the second sleeve 204 is lifted and lowered in the first groove 101, the positioning screw 107 is only in the strip groove and does not affect the lifting stroke of the second sleeve 204. However, when the second screw rod 205 rotates, the positioning screw 107 itself cannot be lifted and lowered in the first through hole 104, and can only drive the second sleeve 204 to be lifted and lowered.

[0074] The outer peripheral side of the second screw 205 is provided with a second screw external thread 2053, the second sleeve internal thread 2041 and the second screw external thread 2053 are adapted to each other, and the second sleeve 204 and the second screw 205 are meshed and driven;

[0075] When the user rotates the knob 4 , the second screw rod 205 rotates, and the second sleeve 204 moves up and down following the second screw rod 205 , thereby driving the limit block 201 to move up and down in the first groove 101 .

[0076] When the desktop clamp is used and is clamped on the side of the desktop panel inside the first groove 101, the user turns the knob 4 to rotate the second screw 205 in the first through hole 104. Due to the limiting activity of the second screw 205, the second screw 205 transmits the transmission force to the second sleeve 204. Under the limiting action of the guide rod 3, the second sleeve 204 cannot rotate on its own, so it can only move according to the spiral transmission principle. The spiral transmission is a mechanical transmission method that utilizes the interaction between the second sleeve 204 and the second screw 205 to convert the rotational motion into linear motion to achieve the transmission effect, thereby realizing the lifting and lowering movement of the limit block 201 in the first groove 101.

[0077] The limiting block 201 is pressed flush against the lower side of the desktop panel, and the first side 102 is pressed flush against the upper side of the desktop panel. In the process of pressing the desktop panel, since there is no surface rotation friction between the first side 102, the limiting block 201 and the upper and lower sides of the desktop panel, the desktop panel is protected from scratches, and the silicone protective layer 5 will not shift or debond with the desktop panel. After the desktop panel is pressed by the first side 102 and the limiting block 201, the desktop panel and the desktop clamp are fixedly limited. The whole operation process is simple, and the desktop is a very practical desktop auxiliary tool, especially suitable for outdoor desktop panel expansion functions, learning or creation, and other scenes that require long-term use of desktop panel expansion.

[0078] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and deformations made to the implementation methods are still within the protection scope of the present invention.
