[0022] It should be noted that the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1-Figure 3As shown, the circuit board clamping and positioning structure proposed by the utility model includes a base 1, and four bottom pads 5 are fixedly connected to the lower surface of the base 1. The bottom pads 5 are made of rubber, and their function is to make the circuit board clamping and positioning structure more stable and not slipping when in use. It also includes: a trapezoidal seat 2 installed on the upper surface of the base 1, and a pair of inclined surfaces of the trapezoidal seats 2 are provided with a plurality of balls 21, and the function of the balls 21 is to make the movable clamping plate 3 slide more smoothly on the inclined surface of the trapezoidal seat 2. A clamping mechanism for quickly clamping and positioning the circuit board is provided on the base 1 and the trapezoidal seat 2; a pressing mechanism is provided on the clamping mechanism, and the pressing mechanism is used to quickly open or close the clamping mechanism after moving up and down.

[0025] Furthermore, the clamping mechanism includes a pair of movable clamps 3 arranged on the trapezoidal seat 2, and a rubber pad is arranged on the side of the movable clamps 3 that contacts the circuit board to prevent the circuit board from being scratched. The bottom of the movable clamps 3 is fixedly connected with a first spring 12, and the function of the first spring 12 is to push the movable clamps 3 upward to return to the original position. The bottom end of the first spring 12 is fixedly connected with a limit clamping plate 11, and a pair of inclined surfaces slidably connected to the movable clamps 3 are arranged on the trapezoidal seat 2, and a pair of card slots 32 are opened at the bottom of the movable clamps 3. The upper surface of the base 1 is fixedly connected with a pair of limit clamping rods 13 that movably penetrate the card slots 32, and a pair of limit clamping plates 11 corresponding to the movable clamps 3 are fixedly connected to the base 1.

[0026] Furthermore, the pressing mechanism includes a placement plate 4 connected to the movable clamping plate 3, and a rubber pad is provided on the upper surface of the placement plate 4 to protect the circuit board being positioned and clamped from being scratched. A slide groove 31 is provided on the top of the movable clamping plate 3, and the slide groove 31 is used for the upwardly moving clamping rod 41 and the clamping block 44 at the bottom of the clamping rod 41 to pass through. A pair of clamping rods 41 for sliding in the slide groove 31 are fixedly connected to the placement plate 4, and a mounting groove 42 is provided at the bottom of the clamping rod 41. A plurality of linearly arranged clamping blocks 44 are provided inside the mounting groove 42, and an inclined bottom of the clamping block 44 is provided, which is used to prevent the slide grooves 31 on the pair of movable clamping plates 3 from being stuck when moving in the opening direction, and vice versa, they will be automatically stuck when closing, and the function of the clamping and opening movable clamping plate 3 is to place the circuit board that needs to be clamped and positioned on the placement plate 4 to wait for clamping and positioning. A plurality of second springs 43 corresponding to the clamping block 44 are fixedly connected inside the mounting groove 42. The second springs 43 are used to make the clamping block 44 move downward and automatically clamp the slide groove 31, thereby keeping the distance between the pair of movable clamping plates 3 fixed. One end of the second spring 43 is fixedly connected to the clamping block 44.

[0027] In this embodiment, when it is necessary to use a circuit board clamping and positioning structure, such as Figure 1As shown, the placement plate 4 is pressed downward, and a pair of clamping rods 41 on the placement plate 4 slide along the slide groove 31 on the top of the moving clamping plate 3, and the bottom of the moving clamping plate 3 slides along the limit clamping rod 13 through the clamping groove 32. When the width of the distance between the tops of the pair of moving clamping plates 3 is larger than the circuit board, as shown in FIG. Figure 3 As shown, at this time, the block 44 in the installation slot 42 is pushed by the elastic force of the second spring 43, so that the bottom end of the block 44 is stuck in the slide slot 31, and the circuit board can be stably placed on the upper surface of the placement plate 4. At this time, the pair of clamping rods 41 are lifted upward, and the pair of clamping rods 41 drive the placement plate 4 and the circuit board on the placement plate 4 to move upward along the slide slot 31. When the clamping rod 41 drives the block 44 at the bottom to resist the slide slot 31, as shown in FIG. Figure 2 As shown, at this time, the pair of movable clamps 3 will be subjected to the elastic thrust of the first spring 12, so that the movable clamps 3 slide upward through the restriction of the upper limit clamp 11 on the base 1, and finally the movable clamps 3 move in the same direction and clamp the circuit board in position, which is convenient and quick.
