[0002] A fingerprint recognition touch screen is an electronic device that can recognize fingerprints. It is mainly used in leadership office, industrial control, multimedia teaching, etc. It is widely used and simple and convenient to use. For example, in the patent number "CN212181445U" and the patent name "A touch screen with fingerprint recognition", when the touch screen is being repaired, it is necessary to switch the front side of the touch screen body to face downward or the back side to face upward. A rotation positioning mechanism is respectively provided in the middle of one side and the middle of the other side of the touch screen body. On the one hand, the rubber holder is used to partially raise the touch screen body 1, thereby avoiding the situation in the prior art that the touch screen body is a plate-like structure and is inconvenient to pick up when placed, and the staff can easily touch the touch screen with one hand. One finger and another finger of the hand contact the dials at one side and the other side of the touch screen body respectively, and when the two dials are pinched towards each other to raise the height of the touch screen body, the other hand can move the touch screen body through the bearing to achieve the effect of convenient rotation and adjustment of the touch screen body to face up with the front side or the back side. At the same time, the force of the adjustment finger picking up the touch screen body is mainly applied to the two dials, avoiding the need to contact the side of the sheet-shaped touch screen body, thereby achieving a better switching effect when, for example, the back side faces upwards to connect the line and the front side faces upwards to observe whether the power-on status after maintenance is normal. However, the above structure still has the following problems in actual use:

[0003] Although the above structure can achieve a better effect of switching use by observing whether the power-on status is normal after maintenance, its touch screen is exposed and easily hit or touched by mistake. The touch screen is relatively fragile and is easily damaged, resulting in economic losses.

[0004] Therefore, we proposed a fingerprint recognition touch screen with screen protection function which can solve the above problems well. Utility Model Content

[0029] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0030] Embodiment 1: In order to solve the problem in the prior art that the touch screen is exposed to the outside and is easily hit or touched by mistake, and the touch screen is relatively fragile, so it is easy to cause it to be damaged, thereby causing economic losses, the following scheme is disclosed, including a frame 1, and the four corners of the frame 1 are wrapped with protective blocks 2; it also includes: a fingerprint touch screen body 3 is embedded and installed on the front side of the frame 1, and a protective plate 4 is provided on the front side of the fingerprint touch screen body 3, and a slider 5 is fixed on the rear side of the protective plate 4, and a sliding connection structure is formed between the slider 5 and the frame 1, and a card hole 6 is opened on the lower surface of the slider 5; a docking block 7 is fitted inside the card hole 6, and a card block 8 is provided on the front side of the docking block 7, and the card block 8 is slidably connected with the docking block 7 through a reset spring 9, and the two ends of the reset spring 9 are respectively fixed to the card block 8 and the docking block 7, and one side of the card block 8 is arranged as an inclined structure, and a card connection is formed between the card block 8 and the card hole 6;

[0031] The fingerprint touch screen body 3 is installed inside the frame 1, thereby realizing the embedded installation of the fingerprint touch screen body 3. At the same time, the four corners of the frame 1 are bonded and fixed with protection blocks 2 to protect the frame 1. At the same time, a protection plate 4 is set on the front side of the frame 1. The protection plate 4 can protect the fingerprint touch screen body 3, thereby preventing the fingerprint touch screen body 3 from being hit or accidentally touched and causing it to be broken. By sliding the protection plate 4 downward, the protection plate 4 drives the slider 5 to move together, and then the slider 5 drives the card hole 6 to dock with the docking block 7. The card block 8 is squeezed by the slider 5, so that the card block 8 is forced to slide into the docking block 7, so that the slider 5 can continue to slide toward the docking block 7. When the slider 5 slides to a certain position, the elastic force of the reset spring 9 drives the card block 8 to reset, so that the card block 8 is engaged with the card hole 6, thereby realizing the limit fixation of the slider 5, and then the protection plate 4 can be limited and fixed, to prevent the protection plate 4 from sliding by itself due to inertia, and thus the fingerprint touch screen body 3 can be better protected.

[0032] Embodiment 2: Different from Embodiment 1, this embodiment facilitates pushing the protection plate 4 upward, so as to facilitate personnel to use the fingerprint touch screen body 3. For details, refer to Figure 1-Figure 4A pull rope 10 is fixed to the rear side of the block 8, and the other end of the pull rope 10 passes through the frame 1 and is fixed to the push-pull rod 11, and the push-pull rod 11 is slidably arranged below the front side of the frame 1, and the front end of the push-pull rod 11 passes through the front side of the frame 1;

[0033] When the fingerprint touch screen body 3 needs to be used, the push-pull rod 11 only needs to be slid downward, so that the push-pull rod 11 drives the pull rope 10 to move together, and the pull rope 10 moves, so that the pull rope 10 pulls the card block 8 to slide into the docking block 7, so that it no longer limits the slider 5. At this time, the protection plate 4 only needs to be slid upward to expose the fingerprint touch screen body 3, and then the fingerprint touch screen body 3 can be used;

[0034] Embodiment 3: Different from Embodiment 2, this embodiment facilitates the replacement of the filter screen 12. Figure 2 and Figure 5-Figure 6 , a filter screen 12 is embedded in the rear side of the frame 1, and a vent hole 13 is opened inside the frame 1 in front of the filter screen 12, and the vent hole 13 is connected to the back of the fingerprint touch screen body 3, a sealing strip 14 is bonded to the outer side of the front side of the filter screen 12, and the sealing strip 14 fits with the limit block, and the outer side of the limit block is fixedly connected to the frame 1, and a card ball 15 is fixed to the rear side of the limit block, and the card ball 15 is made of rubber material, and two groups of card balls 15 are provided, and both groups of card balls 15 form a card connection structure with the filter screen 12;

[0035] A filter 12 is also provided on the rear side of the frame 1. The filter 12 can intercept dust in the air to prevent dust from affecting the operation of the electronic components inside the fingerprint touch screen body 3. The filtered air will enter the back of the fingerprint touch screen body 3 through the vent 13, so that the back of the fingerprint touch screen body 3 can be heat-dissipated to prevent the heat generated by the electronic components on the back of the fingerprint touch screen body 3 from being unable to be discharged during operation, thereby affecting its service life. At the same time, a sealing strip 14 is bonded to the back of the filter 12, and the sealing strip 14 and the limit block are connected. The filter 12 is fitted between the filter screen 12 and the limit block, thereby achieving a sealing effect, and unfiltered air can be prevented from entering through the gap between the filter screen 12 and the limit block, and the limit block can also limit the filter screen 12. At the same time, a card ball 15 is fixed on the limit block. The card ball 15 is made of rubber material, can be deformed by extrusion, and can rebound by itself when not extruded. The card connection between the card ball 15 and the filter screen 12 is used to limit and fix the filter screen 12. When the filter screen 12 needs to be replaced, the filter screen 12 can be disassembled for replacement and cleaning by directly pulling the filter screen 12.
