Abstract
Description
Technical Field
[0001] The utility model relates to the application field of tamper-proof electronic signature plates, in particular to a tamper-proof signature plate. Background Art
[0002] Electronic signature authentication is a real-name authentication through various factors. Every user who passes the real-name authentication will also stamp his or her own CA certificate in the contract when signing the electronic contract. The CA certificate is equivalent to the electronic ID card of each signatory, proving when and when the person signed the contract. The CA certificate is issued by the national authoritative digital certificate center.
[0003] Reliable electronic signature authentication includes two aspects: the identity and content of the signatory and the tamper-proofing of the signature. Tamper-proofing is mainly achieved by digital signature technology. The signed message is calculated using a hash algorithm to obtain a hash value, and then the hash value is signed. The person who receives the digital signature will also use a general hash algorithm to calculate the original text, and then verify it with the signer's public key. If the verification fails, it means that the original text has been tampered with after signing.
[0004] Common offices, public security agencies and bank counters all use tamper-proof signature pads. Tamper-proof signature pads mainly consist of two parts: a signature pad and a signature pen. The signature pad is generally placed above the counter and can be moved at any time. One side of the signature pad is connected to the signature pen by a spring rope. Users can use the signature pen to sign on the signature pad, and the anti-tampering mechanism is implemented through electronic programs. In actual applications, electronic signature pads are generally placed on the counter for use. The screen of the electronic signature pad is fixedly installed. Some signature pads will have a bracket at the bottom to tilt the signature pad to make the user more comfortable and have a better experience when signing, but not all users like to use a tilted signature pad to sign. Therefore, a signature pad that can adjust the angle at any time for different users will bring a better sense of use. Utility Model Content
[0005] Based on this, the purpose of the present invention is to provide a tamper-proof signature pad to solve the technical problems mentioned in the above background.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-tampering signature plate, comprising a base and an anti-tampering signature plate, wherein a first slot hole and a second slot hole are provided on the inner side of the base, and a sleeve is movably installed inside the first slot hole, rubber rings are installed inside the sleeve and the second slot hole, and a metal rod is movably installed inside the rubber ring, and a second strip rod is connected to one side of the metal rod, and square grooves matching the second strip rod are provided on both sides of the anti-tampering signature plate.
[0007] By adopting the above technical solution, by arranging a rubber ring, a metal rod and a second strip rod in the sleeve and the second slot, when the two sets of second strip rods are engaged with the tamper-proof signature plate, the tamper-proof signature plate can drive the second strip rod and the metal rod to rotate in the rubber ring, and the rubber ring in a compressed state has a large friction force, but can still rotate, so that the user can adjust the angle of the tamper-proof signature plate by himself. When the tamper-proof signature plate is adjusted to an inclined angle, the damping effect of the rubber ring prevents the tamper-proof signature plate from returning to a horizontal position due to gravity.
[0008] The utility model is further configured that one side of the sleeve is connected with a first strip rod, and one end of the first strip rod is provided with a linkage block.
[0009] By adopting the above technical solution and providing the first bar and the linkage block, the sleeve can drive the first bar to move by manually pulling the linkage block, thereby driving the sleeve to shrink into the first slot.
[0010] The utility model is further configured such that the first strip rod is slidably penetrated by the outer wall of the base, and the first strip rod extends to the outside of the base.
[0011] By adopting the above technical solution, the first bar and the outer wall of the base are slidably penetrated, so that the first bar and the outer wall of the base cannot rotate but can only slide, thereby preventing the tamper-proof signature plate from driving the sleeve to rotate through the second bar, the metal rod, and the rubber ring when the angle is rotated to adjust.
[0012] The utility model is further configured such that a spring is sleeved on the outside of the first strip-shaped rod, and the spring is located inside the first slot hole.
[0013] By adopting the above technical solution, a spring is sleeved on the outside of the first strip rod, and the sleeve can be pushed to reset by the reset action of the spring, so that the tamper-proof signature plate is clamped by using two sets of second strip rods.
[0014] The utility model is further configured that a plurality of groups of suction cups are arranged at the bottom of the base.
[0015] By adopting the above technical solution and arranging a plurality of suction cups at the bottom of the base, the base can be fixedly installed and used in a designated area of the counter.
[0016] The utility model is further configured that the two groups of rubber rings are in a compressed state.
[0017] By adopting the above technical solution, by setting the rubber ring in a compressed state, the friction between the two groups of metal rods and the rubber ring is relatively large, and the rubber ring forms a damping effect on the metal rod, so that the metal rod can be fixed after rotating to a certain angle, that is, the tamper-proof signature plate can be fixed after rotating and tilting.
[0018] The utility model is further configured that a groove matching the tamper-proof signature plate is formed on the top of the base, and the depth of the groove is greater than the thickness of the tamper-proof signature plate.
[0019] By adopting the above technical solution, a groove is provided on the top of the base, so that the tamper-proof signature plate can be installed inside the base, and the groove has a sufficient depth so that the tamper-proof signature plate can be rotated to a certain angle.
[0020] The utility model is further configured that the tamper-proof signature pad has a built-in tamper-proof program.
[0021] By adopting the above technical solution and setting the signature pad as a tamper-proof signature pad, the security of the user's signature can be guaranteed.
[0022] In summary, the utility model mainly has the following beneficial effects:
[0023] 1. The utility model arranges a rubber ring, a metal rod and a second strip rod in the sleeve and the second slot. When the two sets of second strip rods are engaged with the tamper-proof signature plate, the tamper-proof signature plate can drive the second strip rod and the metal rod to rotate in the rubber ring. The rubber ring in a compressed state has a large friction force, but can still rotate, so that the user can adjust the angle of the tamper-proof signature plate by himself. When the tamper-proof signature plate is adjusted to an inclined angle, the damping effect of the rubber ring prevents the tamper-proof signature plate from returning to a horizontal position due to gravity.
[0024] 2. The utility model arranges a sleeve, a first bar and a spring in the first slot hole so that one group of rubber rings, metal bars and second bar can be contracted, thereby expanding the distance between the two groups of second bar bars, that is, the tamper-proof signature plate can be disassembled from the base, so that the tamper-proof signature plate can be carried around for use. The base is fixed on the counter by a suction cup for use, which reduces the movement of the base position and prevents the tamper-proof signature plate from deviating from the designated area when the user signs with the tamper-proof signature plate.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0036] The following describes an embodiment of the utility model based on its overall structure.
[0037] Embodiment 1
[0038] A tamper-proof signature pad, such as Figure 1-9 As shown, it includes a base 1 and an anti-tampering signature plate 11. The inner side of the base 1 is provided with a first slot hole 2 and a second slot hole 7. The first slot hole 2 and the second slot hole 7 can be used to install a rubber ring 8, a metal rod 9 and a second strip rod 10. The first slot hole 2 is movably installed with a sleeve 3. The sleeve 3 and the second slot hole 7 are both installed with a rubber ring 8. The metal rod 9 is movably installed inside the rubber ring 8. One side of the metal rod 9 is connected to the second strip rod 10. Square grooves 12 matching the second strip rod 10 are provided on both sides of the anti-tampering signature plate 11. When the user uses the anti-tampering signature plate 11 to sign, the angle of the anti-tampering signature plate 11 can be adjusted by manually pressing the rubber ring 8 in a compressed state. The rubber ring 8 in a compressed state has a large friction force, so that the anti-tampering signature plate 11 will not return to the horizontal position due to gravity after being adjusted to an inclined angle.
[0039] See also Figure 2A plurality of suction cups 13 are arranged at the bottom of the base 1. By arranging a plurality of suction cups 13 at the bottom of the base 1, the base 1 can be fixedly installed and used in a designated area of a counter.
[0040] See also Fig. 9 The two groups of rubber rings 8 are in a compressed state. By setting the rubber rings 8 in a compressed state, the friction between the two groups of metal rods 9 and the rubber rings 8 is relatively large. The rubber rings 8 form a damping effect on the metal rods 9, so that the metal rods 9 can be fixed after rotating at a certain angle, that is, the tamper-proof signature plate 11 can be fixed after rotating and tilting.
[0041] See also Figure 3 A groove matching the tamper-proof signature plate 11 is provided on the top of the base 1, and the depth of the groove is greater than the thickness of the tamper-proof signature plate 11. By providing the groove on the top of the base 1, the tamper-proof signature plate 11 can be installed inside the base 1, and the groove has a sufficient depth so that the tamper-proof signature plate 11 can be rotated at a certain angle.
[0042] See also Figure 1 The tamper-proof signature pad 11 has its own tamper-proof program. By setting the signature pad as the tamper-proof signature pad 11, the security of the user's signature can be guaranteed.
[0043] Embodiment 2
[0044] A tamper-proof signature pad, such as Figure 5-6 As shown, a first strip rod 4 is connected to one side of the sleeve 3, and a linkage block 5 is provided at one end of the first strip rod 4. By providing the first strip rod 4 and the linkage block 5, the sleeve 3 can be driven to move the first strip rod 4 by manually pulling the linkage block 5, thereby driving the sleeve 3 to shrink into the first slot 2. By arranging the sleeve 3, the first strip rod 4 and the spring 6 in the first slot 2, one group of rubber rings 8, the metal rod 9 and the second strip rod 10 can be contracted, thereby expanding the distance between the two groups of second strip rods 10, that is, the tamper-proof signature plate 11 can be disassembled from the base 1, so that the tamper-proof signature plate 11 can be carried and used conveniently.
[0045] See also Figure 6 The first bar 4 is slidably penetrated by the outer wall of the base 1, and the first bar 4 extends to the outside of the base 1. By slidably penetrating the first bar 4 and the outer wall of the base 1, the first bar 4 and the outer wall of the base 1 cannot rotate but can only slide, thereby preventing the tamper-proof signature plate 11 from driving the sleeve 3 to rotate through the second bar 10, the metal rod 9, and the rubber ring 8 when the angle is adjusted.
[0046] See also Figure 6A spring 6 is sleeved on the outside of the first strip rod 4, and the spring 6 is located inside the first slot 2. By sleeved on the outside of the first strip rod 4, the sleeve 3 can be pushed to reset by the reset action of the spring 6, so that the tamper-proof signature plate 11 is clamped using two sets of second strip rods 10.
[0047] The working principle of the utility model is: when the user uses the tamper-proof signature plate 11 to sign, the tamper-proof signature plate 11 can be manually pressed to adjust the angle. The rubber ring 8 in the compressed state has a large friction force, so that the tamper-proof signature plate 11 will not return to the horizontal position due to gravity after being adjusted to an inclined angle.
[0048] When it is necessary to remove the tamper-proof signature plate 11 from the base 1, one hand pulls the linkage block 5, which will cause the tamper-proof signature plate 11 to move, thereby causing the sleeve 3 to move. The sleeve 3 will compress the spring 6 when it moves, and the rubber ring 8, metal rod 9 and second strip rod 10 inside the sleeve 3 will also move with the sleeve 3, thereby releasing the restriction of the two sets of second strip rods 10 on the tamper-proof signature plate 11. At this time, the tamper-proof signature plate 11 can be taken out from the inside of the base 1 for easy carrying and use, and the base 1 can be installed in a designated area of the counter through the suction cup 13 at the bottom to avoid the shaking of the tamper-proof signature plate 11. According to the above steps, the tamper-proof signature plate 11 can also be installed in the base 1.
[0049] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
