[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows: For this circuit board testing tooling with protection, by setting the pressing component, it can limit and press the circuit board, so as to better detect the circuit board, thereby improving the detection efficiency of the circuit board. At the same time, through the pressing component, it can prevent the circuit board from shifting, thus avoiding the sides of the circuit board from being knocked and damaged, so as to achieve the function of protecting the circuit board. The specific content is as follows:

[0020] 1. By setting up the pressing component, after starting the second electric push rod through the control end, the output end of the second electric push rod can drive the connecting block to rise. Through the rise of the connecting block, the movement of the movable rod can be driven. At the same time, one side of the bottom surface of the movable rod is rotatably connected to the connecting rod, and the connecting rod is rotatably connected to the fixed block. When the movable rod rises with the second electric push rod, the side of the movable rod away from the second electric push rod descends. At the same time, as the movable rod descends, the pressing rod connected to the movable rod will move along with the descent of the movable rod. At the same time, the pressing rod is rotatably connected to the fixed block. Thus, when the movable rod descends, the side connected to the pressing rod can be driven to descend. Through the descent of one side of the pressing rod, the other side of the pressing rod can be driven to rise, so that the pressing rod rotates around the side rotatably connected to the fixed block as the center point, so that the pressing rod moves outward, making it convenient to place the circuit board on the placement plate. After placing the circuit board on the placement plate, when the second electric push rod is started again through the control end, the output end of the second electric push rod can drive the connecting block to descend. Through the descent of the connecting block, the movement of the movable rod can be driven. At the same time, one side of the bottom surface of the movable rod is rotatably connected to the connecting rod, and the connecting rod is rotatably connected to the fixed block. When the movable rod descends with the electric push rod, the side of the movable rod away from the electric push rod rises. At the same time, as the movable rod rises, the pressing rod connected to the movable rod also moves along with the rise of the movable rod. At the same time, the pressing rod is rotatably connected to the fixed block. Thus, when the movable rod rises, the side connected to the pressing rod can be driven to rise. Through the rise of one side of the pressing rod, the other side of the pressing rod can be driven to descend, so that the pressing rod rotates around the side rotatably connected to the fixed block as the center point, so that the pressing rod moves inward. Thus, after the second electric push rod moves to a suitable position, the pressing plate can press the circuit board placed on the placement plate, so that the circuit board can be positioned, ensuring that the circuit board will not shift during detection. At the same time, through the action of the spring, the circuit board with different thicknesses can be tightly limited. At the same time, through the pressing component, the circuit board can be prevented from shifting, thus avoiding the side of the circuit board from being knocked, resulting in damage to the circuit board, so as to achieve the role of protecting the circuit board;

[0021] 2. By setting up linear guide rails, sliding sleeves, first electric push rods, detection devices and reaction dials, starting the linear guide rails through the control end enables the linear guide rails to drive the movement of the sliding sleeves. Through the movement of the sliding sleeves, the movement of the first electric push rods and detection devices can be driven, so that different positions of the circuit board can be detected. At the same time, starting the first electric push rod through the control end causes the output end of the first electric push rod to descend. By the descent of the output end of the first electric push rod, the descent of the detection device can be driven, so that the detection device can detect circuit boards with different thicknesses, thereby improving the detection efficiency of the circuit board.

Detailed Description of the Preferred Embodiment

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-5, the present utility model provides a technical solution: a circuit board testing tooling with protection, including a box body, one side of the surface of the box body is hinged with a door; one side of the surface of the door is fixedly installed with a handle, a groove is opened on one side of the inside of the box body, an extension board is fixedly installed inside the groove, extension blocks are symmetrically installed on the top surface of the extension board, and a linear guide rail is fixedly connected to one side surface of the extension block; further included are: pressing components symmetrically arranged inside the groove;

[0030] Among them, the pressing component includes a second electric push rod fixedly connected to the groove, and a connecting block is fixedly connected to the top surface of the second electric push rod; among them, a movable rod is rotatably connected to one side surface of the connecting block, and a pressing rod is rotatably connected to the side surface of the movable rod far from the connecting block, as Figures 1-5 shown, by setting the pressing component 13, it can play a role of limiting and pressing the circuit board, so that the circuit board can be better detected, thereby improving the detection efficiency of the circuit board. At the same time, through the pressing component 13, it can prevent the circuit board from shifting, thus avoiding the side of the circuit board from being knocked, which may cause damage to the circuit board. Therefore, it can play a role of protecting the circuit board. At the same time, the model of the linear guide rail 7 is BGXH358E.

[0031] A support rod is penetrated and connected to the side surface of the pressing rod far from the movable rod, a connecting rod is rotatably connected to one side surface of the movable rod near the bottom, a fixed block is rotatably connected to the bottom surface of the connecting rod, and the side surface of the pressing rod far from the support rod is rotatably connected to the fixed block. A spring is sleeved on the side surface of the support rod near the bottom, the bottom surface of the spring is fixedly connected to a pressing plate, and the top surface of the spring is fixedly connected to the pressing rod, as Figure 4 、 5As shown, after starting the second electric push rod 1301 through the control end, the output end of the second electric push rod 1301 can drive the connecting block 1302 to rise. Through the rise of the connecting block 1302, the movable rod 1303 can be driven to move. At the same time, one side of the bottom surface of the movable rod 1303 is rotatably connected to the connecting rod 1306, and the connecting rod 1306 is rotatably connected to the fixed block 1307. When the movable rod 1303 rises with the second electric push rod 1301, the side of the movable rod 1303 away from the second electric push rod 1301 descends. At the same time, as the movable rod 1303 descends, the pressure rod 1304 connected to the movable rod 1303 will move with the descent of the movable rod 1303. At the same time, the pressure rod 1304 is rotatably connected to the fixed block 1307. Thus, when the movable rod 1303 descends, the side connected to the pressure rod 1304 can be driven to descend. Through the descent of one side of the pressure rod 1304, the other side of the pressure rod 1304 can be driven to rise, so that the pressure rod 1304 rotates around the side rotatably connected to the fixed block 1307, so that the pressure rod 1304 moves outward, which is convenient for placing the circuit board on the placement plate 12. At the same time, the spring 1308 is a compression spring in the prior art, and the model of the second electric push rod 1301 is LAM33-A.

[0032] A sliding sleeve is slidably connected to the surface of the linear guide rail. A first electric push rod is fixedly connected to the bottom surface of the sliding sleeve. A detection device is fixedly installed on the bottom surface of the first electric push rod, such as Figure 2 As shown, the model of the first electric push rod 9 is LAM33-A.

[0033] A reaction dial is fixedly installed on one side surface of the groove. A placement plate is fixedly installed in the middle of the top surface of the groove. The placement plate is fixedly connected to the fixed block, such as Figure 2 As shown, by setting the reaction dial, the data generated by detecting the circuit board can be made more obvious. At the same time, the placement plate 12 is used to place the circuit board.

[0034] Working principle: Before using this circuit board testing tool with protection, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 5As shown, after the second electric push rod 1301 is started through the control end, the output end of the second electric push rod 1301 can drive the connecting block 1302 to rise. Through the rise of the connecting block 1302, the movable rod 1303 can be driven to move. At the same time, one side of the bottom surface of the movable rod 1303 is rotatably connected to the connecting rod 1306, and the connecting rod 1306 is rotatably connected to the fixed block 1307. When the movable rod 1303 rises with the second electric push rod 1301, the side of the movable rod 1303 away from the second electric push rod 1301 descends. At the same time, as the movable rod 1303 descends, the pressure rod 1304 connected to the movable rod 1303 will move with the descent of the movable rod 1303. At the same time, the pressure rod 1304 is rotatably connected to the fixed block 1307. Thus, when the movable rod 1303 descends, the side connected to the pressure rod 1304 can be driven to descend. Through the descent of one side of the pressure rod 1304, the other side of the pressure rod 1304 can be driven to rise, so that the pressure rod 1304 rotates around the side rotatably connected to the fixed block 1307, so that the pressure rod 1304 moves outward, which facilitates placing the circuit board on the placement plate 12. After the circuit board is placed on the placement plate 12, when the second electric push rod 1301 is started again through the control end, the output end of the second electric push rod 1301 can drive the connecting block 1302 to descend. Through the descent of the connecting block 1302, the movable rod 1303 can be driven to move. At the same time, one side of the bottom surface of the movable rod 1303 is rotatably connected to the connecting rod 1306, and the connecting rod 1306 is rotatably connected to the fixed block 1307. When the movable rod 1303 descends with the electric push rod, the side of the movable rod 1303 away from the electric push rod rises. At the same time, as the movable rod 1303 rises, the pressure rod 1304 connected to the movable rod 1303 also moves with the rise of the movable rod 1303. At the same time, the pressure rod 1304 is rotatably connected to the fixed block 1307. Thus, when the movable rod 1303 rises, the side connected to the pressure rod 1304 can be driven to rise. Through the rise of one side of the pressure rod 1304, the other side of the pressure rod 1304 can be driven to descend, so that the pressure rod 1304 rotates around the side rotatably connected to the fixed block 1307, so that the pressure rod 1304 moves inward. Thus, after the second electric push rod 1301 moves to a suitable position, the pressing plate 1309 can press the circuit board placed on the placement plate 12, so that the circuit board can be positioned, ensuring that the circuit board does not shift during detection. At the same time, through the action of the spring 1308, circuit boards of different thicknesses can be pressed and limited. At the same time, through the pressing assembly 13, the circuit board can be prevented from shifting, thus avoiding the side of the circuit board from being bumped, resulting in damage to the circuit board, so as to achieve protection of the circuit board.

[0035] Secondly, start the linear guide rail 7 through the control end, so that the linear guide rail 7 can drive the movement of the sliding sleeve 8. Through the movement of the sliding sleeve 8, the movement of the first electric push rod 9 and the detection device 10 can be driven, so that different positions of the circuit board can be detected. At the same time, start the first electric push rod 9 through the control end, so that the output end of the first electric push rod 9 descends. Through the descent of the output end of the first electric push rod 9, the descent of the detection device 10 can be driven, so that the detection device 10 can detect circuit boards with different thicknesses, thereby improving the detection efficiency of the circuit board.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
