[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.

[0036] In the description of the utility model, it should be pointed out that, unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "connection" and "connection" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0037] As shown in Figure 1 - Figure 7 The self-powered test fixture of the foaming device provided by the utility model can detect the devices related to the touch screen 5 and the handle related devices, both of which are fixed on the same bottom plate.

[0038] As shown in Figure 1 - Figure 4 The handle self-powered test part structure includes: handle main control PCBA1 connection structure and handle power supply structure, the handle main control PCBA1 connection structure is used for connecting handle main control PCBA1.

[0039] The handle power supply structure includes first support 110, second support 120, flip cover 130, battery box 140, battery box fixing frame 150, positive metal probe 160 and negative metal probe 170.

[0040] The bottom end of the first support 110 and the second support 120 is fixedly connected with the bottom plate.

[0041] One end of the flip cover 130 is rotatably connected with the first support 110 through a rotating shaft, and two second clamping springs are arranged on the rotating shaft, both of which abut against the first support 110 to prevent the rotating shaft from moving along the axial direction.

[0042] The battery box 140 is rectangular and has an open top end; the battery box fixing frame 150 is in the shape of "Ω", the battery box 140 is invertedly buckled in the recessed portion in the middle of the battery box 140 fixing member, and the battery box 140 and the battery box fixing frame 150 are connected by screws. The battery 180 is a non-consumable product and needs to be replaced.

[0043] The first pillar 110 and the second pillar 120 are spaced apart, and the handle master PCBA1 connecting structure is located between the first pillar 110 and the second pillar 120.

[0044] The flip cover 130 is hinged to the top end of the first pillar 110 and can abut the top of the second pillar 120 after being flipped, at which time the flip cover 130 is parallel to the horizontal plane to stabilize the electrical contact.

[0045] The battery box 140 is used to hold the battery 180, and the positive and negative electrode parts are arranged in the battery box 140 and are electrically connected to the battery 180. The positive and negative electrode parts correspond to the positive and negative electrodes of the battery 180 and realize electrical contact. The battery box fixing frame 150 is connected to the back of the flip cover 130 by a screw. The back of the battery box fixing frame 150 is provided with two screw holes, and the tail ends of the positive and negative metal probes 160 and 170 are provided with threaded structures, so that the positive and negative metal probes 160 and 170 are screwed to the battery box fixing frame 150.

[0046] The positive and negative metal probes 160 and 170 are connected to the positive and negative electrode parts by wires, respectively. The positive and negative metal probes 160 and 170 are used to contact the positive and negative contacts of the handle master PCBA1 when the flip cover 130 abuts the second pillar 120.

[0047] Before testing, the flip cover 130 is first flipped away from the second pillar 120, so that the handle master PCBA1 connecting structure between the first pillar 110 and the second pillar 120 is exposed, and then the handle master PCBA1 is installed on the handle master PCBA1 connecting structure. Subsequently, the flip cover 130 is flipped, and after one end of the flip cover 130 abuts the second pillar 120, the positive and negative metal probes 160 and 170 on the battery box fixing frame 150 contact the positive and negative contacts of the handle master PCBA1, respectively, so that the battery 180 in the battery box 140 supplies power to the handle master PCBA1 for testing. The electrical contact is realized by flipping the flip cover 130, which can avoid disassembling the battery 180, reduce the operation steps, and improve the testing efficiency.

[0048] A first magnet 131 is provided on the back of the flip cover 130, and the number of the first magnets 131 can be two. The top surface of the second pillar 120 is provided with two second magnets 122 magnetically connected to the first magnet 131, so that when the flip cover 130 is flipped and abuts against the second pillar 120, the two first magnets 131 and the two second magnets 122 are attracted one by one, thereby forming a certain attraction between the flip cover 130 and the second pillar 120, so that the positive metal probe 160 and the negative metal probe 170 are in contact with the positive contact and negative contact of the handle main control PCBA1 respectively, and the stability is better.

[0049] In other feasible solutions, a magnet may be provided on only one of the flip cover 130 and the second pillar 120 , while the other one is made of iron material, which can also achieve the magnetic attraction effect.

[0050] A boss 121 is provided on the side of the battery box fixing frame 150 opposite to the flip cover. The boss 121 is used to press the handle main control PCBA1 when the flip cover 130 abuts against the second pillar 120 to prevent the handle main control PCBA1 from moving in the up and down directions, so that the positive metal probe 160 and the negative metal probe 170 can better contact the positive contact and negative contact of the handle main control PCBA1 respectively.

[0051] The top of the second pillar 120 has a hand-grip groove. After completing the test, the user can insert his hand into the hand-grip groove and pull up the flip cover 130 to open the flip cover 130.

[0052] The four corners of the handle main control PCBA1 have four through holes. The handle main control PCBA1 connection structure includes four plug-in posts located at the four corners of the handle main control PCBA1. The plug-in posts are perpendicular to the base plate, so that the through holes at the four corners of the handle main control PCBA1 are plugged into the plug-in posts one by one, thereby preventing the handle main control PCBA1 from moving in the horizontal direction. Combined with the boss 121 pressed thereon, the handle main control PCBA1 can be completely fixed to the base plate.

[0053] like Figure 5 - Figure 7 As shown, the structure of the self-powered test part of the touch screen 5 is as follows:

[0054] The baseplate also features a touchscreen connection structure, a main control PCBA connection structure, a switch PCBA connection structure, a LED light PCBA connection structure, and a battery connection structure. After installing the battery 2, LED light PCBA 3, switch PCBA 4, touch screen 5, and main control PCBA 6 into their respective connection structures, use cables to connect the battery 2, LED light PCBA 3, switch PCBA 4, and touch screen 5 to the main control PCBA 6. Pressing switch PCBA 4 activates the entire system circuit, allowing testing.

[0055] The touch screen 5 is a non-replaceable component and does not need to be replaced frequently, so four copper studs are installed on the base plate, and then the touch screen 5 is fixed to the copper studs with screws. The screen LED light PCBA3 and the screen switch PCBA4 are components that are frequently replaced and tested, so they are fixed to the base plate with press buckles for easy replacement. The screen battery 2 also needs to be replaced after the power is consumed, and is also fixed with press buckles.

[0056] The screen main control PCBA connection structure includes a clamping mechanism, which is used to clamp and fix the screen main control PCBA6. The clamping and fixing facilitates the replacement of the screen main control PCBA6.

[0057] Specifically, the clamping mechanism includes a fixed block 210, a slider 220, a base 230, a screw 240, and a handle 250; the base 230 is fixedly connected to the base. The fixed block 210 is connected to the base 230 by screws. The slider 220 and the base 230 are connected in a straight line, and slide rails and slide grooves are correspondingly provided on the two, so that the slider 220 can only slide relative to the base 230 but cannot rotate. The threaded portion of the screw 240 is threadedly connected to the slider 220, and rotating the screw 240 can drive the slider 220 to move closer to or away from the fixed block 210 relative to the base 230 in a straight line. The non-threaded portion of the screw 240 is rotatably connected to the fixed block 210; the handle 250 is connected to the non-threaded end of the screw 240, and the fixed block 210 is located between the slider 220 and the handle 250. When the screw 240 is rotated, the external thread on the screw 240 will rotate and the internal thread of the slider 220 will move along with it. The left and right directions of the slider 220 are restricted by the slide rail of the base 230, so the slider 220 will not rotate, but will only move forward or backward along with the thread. The forward and backward movement of the slider 220 is used to install and remove the screen main control PCBA6. One end of the screen main control PCBA6 is fixed in the groove 270 of the fixed block 210, and the other end is fixed in the groove 270 of the slider 220. The above-mentioned clamping mechanism has firm clamping, simple installation and removal, and strong adaptability.

[0058] like Figure 6As shown, the non-threaded portion of the screw 240 is provided with two annular grooves spaced apart from each other, one on opposite sides of the fixed block 210. A first retaining spring 260 is disposed in each annular groove to prevent the screw 240 from linearly moving relative to the fixed block 210. When the screw 240 is rotated, it is restrained by the first retaining spring 260 and thus does not slide in the longitudinal direction. Instead, the rotation of the external thread of the screw 240 causes the internal thread of the slider 220 to follow the movement.

[0059] like Figure 7 As shown, the slider 220 and the fixed block 210 are both provided with grooves 270 for supporting the screen main control PCBA6, and the side walls of the grooves 270 are used to stop and limit the screen main control PCBA6. The size of the grooves 270 corresponds to the size of the screen main control PCBA6 to be detected, and the two ends of the screen main control PCBA6 are respectively prevented from being in the two grooves 270. The grooves 270 prevent the screen main control PCBA6 from moving in the horizontal direction.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
