It uses a clamping part to cover a template, and the bottom of the template has several regularly arranged suction parts that adsorb and fix the position of steel sheets. These suction parts are detachably installed on the bottom of the template. This invention provides a PCB board surface mount reflow carrier with accurate positioning, no movement of electronic components, and wide applicability. However, this patent still has the following problems in actual use:

[0004] When installing or removing the mounting components, the screws on both sides need to be turned. However, other disassembly tools are needed to turn the bolts, which makes the installation of the mounting components cumbersome and unable to be done quickly.

[0005] A PCB board surface mount reflow carrier is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a PCB board surface mount reflow carrier to solve the problem mentioned in the background art that when installing or removing mounting components, it is necessary to tighten the screws on both sides to install or remove them. However, when tightening the bolts, other disassembly tools are required, which makes the installation of mounting components cumbersome and unable to be done quickly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a PCB board surface mount reflow carrier, including a base and a template mounted on the top of the base, wherein the template is slidably connected to an installation component;

[0008] Also includes:

[0009] The template is provided with a limiting component inside. The limiting component includes a through groove, and a support block is fixedly connected inside the through groove. A limiting rod is fixedly connected inside the through groove, and a slider is slidably connected to the outside of the limiting rod. A push rod is fixedly connected to one side of the slider.

[0010] Among them, a first locking block is fixedly connected to the upper part of the other side of the slider, and a connecting rod is fixedly connected to the lower part of the other side of the slider, and the connecting rod slides inside the support block;

[0011] The through groove is fixedly connected to a connecting piece, and the front of the connecting piece is rotatably connected to a rotating bar. The connecting rod is rotatably connected to the rotating bar, and the connecting rod and the rotating bar's pivot point are slidable.

[0012] Preferably, a mounting plate is fixedly connected to the front of the connecting plate, and a first spring is fixedly connected to one side of the mounting plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This PCB board surface mount reflow carrier, when fixing and installing mounting components, only requires controlling the movement of a push rod to fix and install the components, making the installation of mounting components faster and more convenient. The specific details are as follows:

[0019] 1. Pushing the push rod causes the slider to move, which in turn causes the first locking block to engage inside the mounting component. Simultaneously, the slider's movement causes the connecting rod to move, which in turn causes the rotating bar to rotate. The rotating bar then compresses the moving piece, causing it to move. At the same time, the first spring is stretched, and the moving piece's movement causes the second locking block to move, engaging the other side of the mounting component. This allows for positioning and installation of both sides of the mounting component using only one control unit, making installation more convenient.

[0020] 2. When the first and second locking blocks engage and limit the installation component, the locking groove corresponds to the locking block. At this time, the second spring will rebound, causing the locking block to limit the push rod, thus making the installation of the installation component more secure. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 5This utility model provides a technical solution: a PCB board surface mount reflow carrier, including a base 1 and a template 2 mounted on the top of the base 1, with a mounting component 201 slidably connected inside the template 2; a limiting component 3 is provided inside the template 2, the limiting component 3 including a through groove 301, with a support block 302 fixedly connected inside the through groove 301, and a limiting rod 303 fixedly connected inside the through groove 301, and a slider 304 slidably connected outside the limiting rod 303, with a push rod 305 fixedly connected to one side of the slider 304; wherein, a first locking block 307 is fixedly connected to the upper part of the other side of the slider 304, and a connecting rod 306 is fixedly connected to the lower part of the other side of the slider 304, and the connecting rod 306 slides inside the support block 302; wherein, a connecting piece 308 is fixedly connected inside the through groove 301, and a rotating strip 309 is rotatably connected to the front side of the connecting piece 308, such as... Figure 3-5 As shown, the mounting piece 201 is slid into the interior of the template 2, and then the push rod 305 is pushed. The push rod 305 will then drive the slider 304 to move, and the slider 304 will then drive the first locking block 307 to lock into the interior of the mounting piece 201. At the same time, as the slider 304 moves, it will drive the connecting rod 306 to move, and the connecting rod 306 will drive the rotating bar 309 to rotate. The connecting rod 306 and the rotating bar 309 are rotatably connected, and the pivot of the connecting rod 306 and the rotating bar 309 can slide.

[0029] A mounting plate 310 is fixedly connected to the front of the connecting piece 308, and a first spring 311 is fixedly connected to one side of the mounting plate 310. A movable piece 312 is fixedly connected to one side of the first spring 311, and a first telescopic rod 313 is fixedly connected between the movable piece 312 and the mounting piece 310. A second locking block 314 is fixedly connected to one side of the movable piece 312, and symmetrically arranged slots 315 are provided inside the mounting component 201. Figure 4 , 5 As shown, the rotating bar 309 will squeeze the movable piece 312, causing the movable piece 312 to move. At the same time, the first spring 311 is stretched. Simultaneously, as the movable piece 312 moves, it will drive the second locking block 314 to move. Then, the second locking block 314 will lock into the other side of the mounting piece 201, so that the positioning and installation of both sides of the mounting piece 201 can be achieved through only one control terminal, making the installation of the mounting piece 201 more convenient. The first locking block 307 and the second locking block 314 are the same size and shape.

[0030] A fixing component 4 is provided on one side of the template 2. The fixing component 4 includes a mounting block 401, and a second spring 402 is fixedly connected to the bottom of the mounting block 401. A snap-fit ​​block 403 is fixedly connected to the bottom of the second spring 402. A second telescopic rod 405 is fixedly connected between the snap-fit ​​block 403 and the mounting block 401. Figure 3As shown, while the first locking block 307 and the second locking block 314 engage and limit the mounting part 201, the locking groove 404 corresponds to the locking block 403. At this time, the second spring 402 will rebound, so that the locking block 403 limits the push rod 305, thereby making the installation of the mounting part 201 more secure. The push rod 305 has a locking groove 404 inside, and the locking block 403 abuts against the push rod 305.

[0031] Working principle: Before using this type of PCB board surface mount reflow carrier, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 5 As shown, firstly, the mounting component 201 is slid into the interior of the template 2, and then the push rod 305 is pushed. The push rod 305 then moves the slider 304, which in turn moves the first locking block 307 into the interior of the mounting component 201. Simultaneously, as the slider 304 moves, it moves the connecting rod 306, which in turn moves the rotating bar 309. The rotating bar 309 then presses against the moving piece 312, causing the moving piece 312 to move. At the same time, the first spring 311 is stretched. Simultaneously, as the moving piece 312 moves, it moves the second locking block 314, which then locks into the other side of the mounting component 201. This allows for the positioning and installation of both sides of the mounting component 201 through a single control terminal, making the installation of the mounting component 201 more convenient.

[0032] When the first locking block 307 and the second locking block 314 engage and limit the mounting part 201, the locking groove 404 corresponds to the locking block 403. At this time, the second spring 402 will rebound, causing the locking block 403 to limit the push rod 305, thereby making the installation of the mounting part 201 more secure.

[0033] 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
