[0002] With the rapid development of information technology, data security has become a key concern for individuals and businesses. Among the many data protection measures, physical hardware keys, as a crucial authentication tool, are widely used in various scenarios requiring high security, such as financial transactions and enterprise information security access control. Traditional key devices often utilize a simple USB interface design, leaving them exposed. While this approach is convenient, it has significant drawbacks.
[0003] Since the USB interface is directly exposed to the outside, it is easily affected by the external environment, such as collisions and scratches, which may cause damage to the USB interface and affect its normal use. In the absence of effective dust and water-proof measures, dust or moisture may invade the inside of the device when used or carried for a long time, causing circuit short circuits or other failures, reducing the service life of the device. In actual application, once the key is damaged, it means that the device is locked, causing serious losses to the user. Therefore, a data security verification device is needed to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a data security verification device with the advantages of automatic expansion and contraction and excellent dust and water resistance, thereby solving the problems of traditional key devices being easily damaged and water and dust ingress due to the USB interface being directly exposed to the outside.

The elastic protective film on the outer side of the outer shell is made of polyurea material, which can absorb impact force and resist wear, protecting the integrity of the outer shell. When the key body retracts, the silica gel buffer airbag in the outer shell releases pressure through the exhaust hole, absorbing the instantaneous impact energy and preventing the internal circuit board from being damaged due to sudden stop vibration. At the same time, the flexible plug board is linked with the vertical plate through the guiding flange and automatically inserts into the chute to form a sealing barrier when the key body retracts, effectively blocking the intrusion of dust and water stains into the interior, solving the problems of pollution, oxidation and short circuit caused by the exposure of the interface of traditional devices, and prolonging the service life of the interface.
[0015] 2. In the present utility model, a guiding chute and a positioning sleeve are arranged inside the outer shell to restrict the sliding trajectory of the key body, avoid jamming or reset failure caused by spring offset, ensure the accuracy and smoothness of each telescopic movement, and the vertical plate and the side wall of the chute are fixed by magnetic adsorption to balance the resilience of the spring, prevent the USB interface from accidentally retracting due to external friction when connecting to a computer, and ensure the stability of the data transmission process. This dual-guiding and magnetic-locking design solves the problem of connection interruption caused by the loose structure of traditional devices and improves the operation reliability.

[0023] Please refer to Figures 1 - 6 , a data security verification device, including a key body 1, and a protection mechanism 2 movably connected to the outside of the key body 1;
[0024] The key body 1 includes an inner shell 101 and a data board 103. A USB interface 102 is provided on the data board 103. The inner shell 101 is fixedly installed at the outer end of the data board 103. The protection mechanism 2 includes an outer shell 201, an elastic protective film 202, a flexible insertion plate 203 and a spring 206. The outer shell 201 is sleeved on the outer end of the key body 1 and is slidably connected thereto. The elastic protective film 202 is fixedly installed on the outer end face of the outer shell 201. The flexible insertion plate 203 is installed on the inner end face of the outer shell 201 and is slidably connected thereto. A second chute 2011 is provided on the upper end face of the outer shell 201. A vertical plate 104 that is slidably engaged with the second chute 2011 is fixedly installed at the top of the inner shell 101. The top of the flexible insertion plate 203 is fixed to the side end face of the vertical plate 104. The spring 206 is installed between the inner shell 101 and the outer shell 201.
[0025] The key body 1 and the outer shell 201 are elastically and slidably connected through the spring 206, so that when the key body 1 is not in use, it can be automatically retracted into the outer shell 201 under the reset action of the spring 206, avoiding the key body 1 from being knocked. An elastic protective film 202 is added to the outside of the outer shell 201 to further improve the protection effect, and the first chute 2014 is blocked by the flexible insertion plate 203 to prevent water from entering or dust from falling into the outer shell 201, improving the safety and stability of the device.
[0026] Further, a first chute 2014 that is slidably engaged with the USB interface 102 is provided on the front end face of the outer shell 201. A guiding flange 2013 for guiding the sliding direction of the flexible insertion plate 203 is provided on the inner end face of the outer shell 201. A slot 2015 that is slidably engaged with the flexible insertion plate 203 is provided at the upper end of the inner end face of the first chute 2014.
[0027] The edge of the flexible insertion plate 203 is guided by the guiding flange 2013, so that the flexible insertion plate 203 can slide along the guiding flange 2013. When the key body 1 is slid outwards through the vertical plate 104, the vertical plate 104 pulls the flexible insertion plate 203, causing it to slide downwards at the end away from the vertical plate 104, thereby automatically opening the first chute 2014. When the key body 1 is retracted into the device, the vertical plate 104 pushes the flexible insertion plate 203 in the reverse direction, causing it to insert into the slot 2015, thereby sealing the first chute 2014 and preventing dust from falling into or water from entering the outer shell 201, effectively protecting the key body 1.
[0028] Further, a second magnet 1041 is provided on the vertical plate 104. A first magnet 2012 that is adsorbed and engaged with the second magnet 1041 is provided on the side end face of the second chute 2011.
[0029] When the vertical plate 104 slides forward to the end of the chute, the vertical plate 104 is adsorbed by the first magnet 2012 and the second magnet 1041 to keep it in contact with the side wall of the chute, so as to balance the elasticity of the spring 206 and prevent the USB interface 102 from having insufficient friction with the computer interface during use, resulting in the key body 1 being automatically retracted into the housing 201.
[0030] Furthermore, positioning sleeves 1011 for fixing the spring 206 are provided on the inner end face of the housing 201 and the front end face of the inner housing 101, and a guiding chute 2016 for slidingly cooperating with the inner housing 101 is provided on the inner end face of the housing 201.
[0031] The spring 206 is fixed by the positioning sleeve 1011 to prevent the spring 206 from shifting during use, resulting in the loss of elasticity between the inner housing 101 and the housing 201 and the inability to automatically contract. By providing the guiding chute 2016 on the inner end face of the housing 201, the side of the inner housing 101 is stuck in the inner edge of the guiding chute 2016 and slides along the guiding chute 2016 to guide its sliding direction, so that the key body 1 can accurately and stably slide in and out each time.
[0032] Furthermore, a buffer airbag 204 is provided at the end of the inner end face of the housing 201 away from the first chute 2014. The buffer airbag 204 is made of silica gel material, and an exhaust hole 2041 is provided on the side end face of the buffer airbag 204.
[0033] When the key body 1 slides inward rapidly under the reset action of the first spring 206, the key body 1 impacts the buffer airbag 204, and the buffer airbag 204 slowly deflates through the exhaust hole 2041, thereby preventing the key body 1 from suddenly stopping and causing damage to the circuit board, and further improving the stability of the device.
[0034] Furthermore, the elastic protective film 202 is made of polyurea material.
[0035] The polyurea material has good elasticity, wear resistance and corrosion resistance, and can effectively protect the housing 201 and prevent the housing 201 from being broken when bumped.
[0036] Furthermore, the flexible plug board 203 is made of polypropylene material.
[0037] Polypropylene has good corrosion resistance, wear resistance and weather resistance, a long service life, and basically does not need to be replaced during repeated use.
[0038] When this device is in use and the key body 1 needs to be used, the key body 1 is pushed outwards through the vertical plate 104. Since the key body 1 and the outer shell 201 are elastically slidably connected by a spring 206, the vertical plate 104 pulls the flexible plug plate 203, causing it to slide down along the guiding flange 2013 on the inner end face of the outer shell 201 away from the end of the vertical plate 104, thereby automatically opening the first sliding groove 2014 that slidably cooperates with the USB interface 102 on the front end face of the outer shell 201. At this time, the USB interface 102 on the data plate 103 of the key body 1 can be exposed for connecting devices such as a computer. When the vertical plate 104 slides forward to the end of the second sliding groove 2011, the second magnet 1041 on the vertical plate 104 adsorbs to the first magnet 2012 on the side end face of the second sliding groove 2011, keeping the vertical plate 104 in close contact with the side wall of the sliding groove to balance the elasticity of the spring 206, and preventing the key body 1 from automatically retracting into the outer shell 201 due to insufficient friction between the USB interface 102 and the computer interface during use. At the same time, when the device accidentally drops, at the moment of landing, whether due to the inertial effect or the pressure effect when hitting the USB interface 102 end, the balance of the magnetic force and the elastic force can be broken, causing the key body 1 to instantly retract into the protective shell. After use, when the key body 1 is released, under the reset action of the spring 206, the key body 1 automatically retracts into the outer shell 201, and the vertical plate 104 reversely pushes the flexible plug plate 203, causing it to insert into the slot 2015 at the upper end of the inner end face of the first sliding groove 2014, thereby sealing the first sliding groove 2014 to prevent dust from falling into or water from entering the outer shell 201, effectively protecting the key body 1. During the process of the key body 1 retracting, if it slides inwards rapidly under the reset action of the spring 206, it will hit the buffer airbag 204 provided at the end of the inner end face of the outer shell 201 away from the first sliding groove 2014. The buffer airbag 204 is made of silica gel material and has exhaust holes 2041 on its side end face, and slowly deflates to prevent damage to the circuit board caused by the sudden stop of the key body 1.
[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
