DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0027] like Figure 1 As shown, a clamping device for television production includes a workbench 1 and two chute 2 symmetrically opened on both sides of the workbench. A clamping member 3 is slidably connected in each chute. The two clamping members cooperate with each other. An adjustment mechanism for adjusting the distance between the two clamping members is provided under the workbench. Figure 2 and Figure 3As shown, the adjustment mechanism includes a fixed plate 4, a rotating shaft 5, an adjusting disk 6, and a crank 7. The fixed plate is connected to the bottom of the workbench, the rotating shaft passes through the fixed plate and is rotatably connected to the fixed plate, the upper end of the rotating shaft is connected to the adjusting disk, and the lower end is connected to the crank. A rocker arm 8 is hinged between the adjusting disk and each clamping member, one end of the rocker arm is hinged to the clamping member on the corresponding side, and the other end is hinged to the lower edge of the adjusting disk. The positions at which the two rocker arms are hinged to the adjusting disk are symmetrical. When the crank is rotated to drive the adjusting disk to rotate, the adjusting disk pulls the rocker arm to swing, so that the clamping member slides in the slide groove, thereby changing the distance between the two clamping members.

[0028] The bottom of the workbench is equipped with a locking mechanism for locking the rotation angle of the adjustment disk, which can effectively lock and fix the positions of the two clamps. Figure 2 and Figure 3 As shown, the locking mechanism includes a top plate 9, a locking disk 10, and a spring 11. The top plate is located at the bottom of the workbench and is connected to the spring at the bottom end. The spring is connected to the locking disk. The bottom end surface of the locking disk is provided with a plurality of positioning rods 12 distributed in a circumferential array. The plurality of positioning rods are connected to a plurality of positioning grooves 13 distributed in a circumferential array on the upper end surface of the adjusting disk. The number and size of the positioning rods match the number and size of the positioning grooves. When the plurality of positioning rods are inserted into the positioning grooves one by one, the locking disk and the adjusting disk can be fixed, ensuring the stability of the product clamping. The clamping member is L-shaped, and its surface is covered with an elastic pad 16, which not only protects the product from surface damage but also satisfies the micro-adjustment of the clamping width. To further improve the stability of the locking disk, a guide rod 14 is connected to the middle of the lower end of the top plate. The guide rod is rotatably connected to the guide groove 601 located in the middle of the upper end of the adjusting disk. The locking disk and the spring are both sleeved on the guide rod and slidably connected to the guide rod. An adjusting handle 15 is provided on the locking disk. The operator holds the adjusting handle and pushes it upwards to disengage the positioning rod from the positioning groove, thereby releasing the fixing of the locking disk to the adjusting disk.

[0029] like Figure 1 and Figure 2 As shown, in order to further improve the stability of the clamping, telescopic rods 17 are provided on both sides of each clamping member. The length direction of the telescopic rods is perpendicular to the length direction of the slide groove. The end of each telescopic rod is provided with an auxiliary positioning member 18, which is made of rubber to prevent the surface of the product from being worn. Each clamping member is assembled and connected to a support block 20 by a bolt 19 on the side away from the other clamping member. The two telescopic rods on the clamping member are connected to the two sides of the support block to facilitate the disassembly and assembly of the telescopic rod and the clamping member. The telescopic rod includes a hollow tube 1701, a movable rod 1702 and a locking screw 1703. One end of the movable rod is connected to the auxiliary positioning member, and the other end is arranged in the hollow tube and is slidably connected to the hollow tube. A locking screw is threadedly connected to the hollow tube. The end of the locking screw conflicts with the movable rod. The length of the telescopic rod can be adjusted by controlling the tightness of the locking screw.

[0030] The working principle of this utility model is as follows:

[0031] like Figures 1 to 3 As shown, place the clamped product or workpiece on the workbench 1 so that it is located between the two clamping members 3, then push the adjustment handle 15 upward to disengage the positioning rod 12 from the positioning groove 13, rotate the crank 7 to adjust the distance between the two clamping members 3, then release the adjustment handle 15, use the spring 11 to make the positioning rod 12 correspond to the positioning groove 13 one by one, and then adjust the length of each telescopic rod 17 according to actual needs so that the corresponding auxiliary positioning member 18 contacts the edge of the product or workpiece.

[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
