Description

Technical Field

[0001] The utility model belongs to the technical field of access control equipment, and specifically relates to an intelligent access control and access control card recognition device. Background Art

[0002] The smart access control uses a contactless card reader to manage the access and exit of personnel. Its core component is the identifier. When the matching access card is placed on the identifier, the identifier can read the information in the access card to control the access and exit of personnel. Since the access card is usually set outdoors, the rain, snow and sunlight in the environment will cause the identifier to age. In order to extend the service life of the identifier, a protective shell is usually set on the outside of the identifier to reduce the damage to the identifier caused by rain, snow and sunlight.

[0003] The protective shell of the existing intelligent access control card recognition device generally needs to be opened and closed manually. Since the operator holds the access card in one hand, he needs to use the other hand to open and close the protective shell, which requires two-hand operation. This switching method is cumbersome to operate and inconvenient. The identifier is generally installed vertically or horizontally. During identification, the operator needs to use his hand to vertically or horizontally fit the access card and the identifier. The rotation angle of the operator's wrist is limited. If a part of the access card is forced to vertically or parallely fit the identifier, it is easy to cause the access card to bend and damaged, which is inconvenient. Utility Model Content

[0004] The purpose of the utility model is to provide an intelligent access control and access card recognition device, which can automatically open the protective cover through a lifting switch mechanism under the drive of the hand preparing to place the access card, so as to facilitate one-handed operation and improve convenience. Moreover, through the inclined plate arranged at an angle, the access card is placed on the identifier at an angle during the recognition process, which reduces the situation where the access card is bent and damaged, thereby improving convenience.

[0005] The technical solution adopted by the utility model is as follows:

[0006] An intelligent access control card recognition device includes a mounting plate, one side of which is fixedly connected to an inclined plate, the inclined plate being inclined downward along a horizontal plane, and further comprising:

[0007] an identifier, the identifier being mounted on the inclined plate;

[0008] A protective cover, which is arranged outside the identifier, and the bottom of the protective cover is slidably connected to the inclined plate;

[0009] A lifting switch mechanism, the lifting switch mechanism is installed between the protective cover and the tilting plate, and the lifting switch mechanism is rotatably connected to the top of the protective cover;

[0010] When the operator places the access card on the identifier from top to bottom with his hand, the lifting switch mechanism automatically opens the protective cover driven by the hand. When the hand is separated from the lifting switch mechanism, the protective cover slides downward under the action of gravity and automatically closes.

[0011] The lifting switch mechanism includes a lifting rod rotatably connected to both sides of the top of the protective cover, the lifting rod is slidably connected to the inclined plate, the lower end of the lifting rod is slidably connected to a rotating rod, the rotating rod is rotatably connected to the inclined plate, and the end of the rotating rod away from the lifting rod is rotatably connected to a hand pressure rod.

[0012] A first slide groove is provided between the lifting rod and the inclined plate. The first slide groove is fixedly connected to the inclined plate, and the first slide groove is slidably matched with the lifting rod.

[0013] A sliding block is fixedly connected to the bottom of the lifting rod, and a sliding hole is formed at one end of the rotating rod close to the lifting rod, and the sliding hole is slidably matched with the sliding block.

[0014] Two rollers are rotatably connected to the two sides of the bottom of the protective cover, and a second slide groove is arranged on the outer side of the roller. The second slide groove is fixedly connected to the inclined plate, and the second slide groove is slidably matched with the roller.

[0015] A stopper is provided at one end of the second slide slot, and the stopper is fixedly connected to the second slide slot.

[0016] The technical effects achieved by the utility model are:

[0017] The lifting switch mechanism provided in the utility model can automatically open and close the protective cover under the drive of the hand preparing to place the access card. When the operator places the access card on the identifier from top to bottom with his hand, when the hand presses the lifting switch mechanism downward, the lifting switch mechanism drives the top of the protective cover to move upward, and the bottom of the protective cover moves inward along the inclined plate, and the identifier is exposed from the inside of the protective cover, thereby opening the protective cover. At this time, the access card can be placed on the identifier for identification. When the identification is completed, the hand is moved upward to leave the lifting switch mechanism, and the protective cover returns to its initial position under the action of gravity, thereby closing the protective cover, which is convenient for one-handed operation and improves convenience.

[0018] The inclined plate of the utility model is inclined along the horizontal plane, so that the identifier installed on the inclined plate is also inclined, which is convenient for the operator to place the access card on the identifier by hand at an angle, reducing the rotation angle of the operator's wrist, thereby reducing the situation where the access card is bent and damaged, and improving convenience.

[0027] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of the utility model, and does not strictly limit the scope of protection of the specific request of the utility model.

[0028] like Figure 1 and Figure 2 As shown, an intelligent access control card recognition device includes a mounting plate 10, one side of the mounting plate 10 is fixedly connected to an inclined plate 11, and the inclined plate 11 is inclined downward along a horizontal plane, and also includes:

[0029] The identifier 20 is mounted on the inclined plate 11;

[0030] A protective cover 30, which is disposed outside the identifier 20, and a bottom of the protective cover 30 is slidably connected to the inclined plate 11;

[0031] A lifting switch mechanism 40, which is installed between the protective cover 30 and the tilting plate 11, and the lifting switch mechanism 40 is rotatably connected to the top of the protective cover 30;

[0032] When the operator places the access card on the identifier 20 from top to bottom by hand, the lifting switch mechanism 40 automatically opens the protective cover 30 driven by the hand. When the hand is separated from the lifting switch mechanism 40, the protective cover 30 slides downward under the action of gravity and automatically closes.

[0033] In this embodiment, when the operator holds the access card and places it on the identifier 20 from top to bottom, the hand drives the lifting switch mechanism 40 to operate. After the lifting switch mechanism 40 operates, the top of the protective cover 30 moves upward, so that the bottom of the protective cover 30 slides inward along the inclined plate 11, thereby opening the protective cover 30 to expose the identifier 20 inside the protective cover 30. After the identifier 20 recognizes the access card, the operator holds the access card and moves it upward, so that the hand is separated from the lifting switch mechanism 40. The protective cover 30 slides downward along the inclined inclined plate 11 under the action of its own gravity, so that the protective cover 30 The bottom of the protective cover 30 slides outward along the inclined plate 11, thereby closing the protective cover 30 so that the protective cover 30 covers the identifier 20, thereby protecting the identifier 20, and then the lifting switch mechanism 40 automatically opens and closes the protective cover 30 under the control of the operator's hand, which is convenient for one-handed operation and improves convenience. The inclined inclined plate 11 makes the identifier 20 also inclined along the inclined plate 11, which is convenient for the operator to place the access card on the identifier 20 by hand at an angle, reducing the rotation angle of the operator's wrist, thereby reducing the possibility of the access card being bent and damaged, thereby improving convenience.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the lifting switch mechanism 40 includes a lifting rod 401 rotatably connected to both sides of the top of the protective cover 30, the lifting rod 401 is slidably connected to the inclined plate 11, the lower end of the lifting rod 401 is slidably connected to a rotating rod 402, the rotating rod 402 is rotatably connected to the inclined plate 11, and the end of the rotating rod 402 away from the lifting rod 401 is rotatably connected to a hand pressure rod 403.

[0035] It should be noted that the lifting rod 401 and the rotating rod 402 are also rotationally connected.

[0036] In this embodiment, when the hand pressure rod 403 is pressed down by hand, the hand pressure rod 403 drives the end of the rotating rod 402 close to the hand pressure rod 403 to rotate downward, so that the end of the rotating rod 402 close to the lifting rod 401 rotates upward and drives the lifting rod 401 to move upward, and the lifting rod 401 drives the top of the protective cover 30 to move upward, thereby facilitating the opening of the protective cover 30.

[0037] like Figure 3 As shown, a first slide groove 50 is provided between the lifting rod 401 and the inclined plate 11 . The first slide groove 50 is fixedly connected to the inclined plate 11 , and the first slide groove 50 is slidably matched with the lifting rod 401 .

[0038] It should be noted that the first chute 50 and the inclined plate 11 are welded.

[0039] In this embodiment, the lifting rod 401 cooperates with the first sliding groove 50 so that the lifting rod 401 slides along the inclined plate 11 more stably.

[0040] like Figure 3 As shown, a slider 4011 is fixedly connected to the bottom of the lifting rod 401 , and a sliding hole 4021 is provided at one end of the rotating rod 402 close to the lifting rod 401 , and the sliding hole 4021 is slidably matched with the slider 4011 .

[0041] It should be noted that the cross-sectional shape of the slider 4011 is circular, and the slider 4011 and the sliding hole 4021 are rotationally matched.

[0042] In this embodiment, when the rotating rod 402 rotates upward near one end of the lifting rod 401, a relative displacement occurs between the slider 4011 and the sliding hole 4021, so that the rotating rod 402 drives the slider 4011 to move upward through the sliding hole 4021. At the same time, the slider 4011 also slides and rotates inside the sliding hole 4021, so that the slider 4011 drives the lifting rod 401 to move upward, thereby causing the lifting switch mechanism 40 to drive the top of the protective cover 30 to move upward, thereby facilitating the opening of the protective cover 30.

[0043] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, two rollers 301 are rotatably connected to the bottom sides of the protective cover 30 , and a second slide groove 60 is provided on the outer side of the roller 301 . The second slide groove 60 is fixedly connected to the inclined plate 11 , and the second slide groove 60 and the roller 301 are slidably matched.

[0044] It should be noted that the cross-sectional shape of the second slide groove 60 is L-shaped.

[0045] In this embodiment, when the bottom of the protective cover 30 slides along the inclined plate 11, the protective cover 30 drives the roller 301 to slide along the second slide groove 60. The sliding cooperation between the second slide groove 60 and the roller 301 makes the sliding process of the protective cover 30 along the inclined plate 11 more stable. In this process, since the protective cover 30 and the roller 301 are rotatably connected, the angle between the protective cover 30 and the second slide groove 60 changes during the sliding of the roller 301 along the second slide groove 60, which facilitates the opening of the protective cover 30.

[0046] like Figure 5 and Figure 6 As shown, a stopper 601 is provided at one end of the second slide slot 60 , and the stopper 601 is fixedly connected to the second slide slot 60 .

[0047] In this embodiment, when the bottom of the protective cover 30 slides outward along the inclined plate 11 , the stopper 601 prevents the roller 301 from sliding outward along the second slide groove 60 , thereby preventing the protective cover 30 from being separated from the inclined plate 11 .

[0048] The working principle of the utility model is as follows: first, the handheld access card is placed on the identifier 20 from top to bottom, and the hand contacts the lifting switch mechanism 40 to drive the lifting switch mechanism 40 to move, so that the bottom of the protective cover 30 slides inward along the inclined plate 11, thereby opening the protective cover 30 to place the access card, and then, the handheld access card moves upward, and the protective cover 30 slides downward under the action of its own gravity, thereby closing the protective cover 30, so that the lifting switch mechanism 40 automatically opens and closes the protective cover 30 driven by the operator's hand, which is convenient for one-handed operation and improves convenience. In addition, the identifier 20 is tilted along the inclined plate 11, which is convenient for the operator to hold the access card and place it on the identifier 20 at an angle, thereby reducing the possibility of the access card being bent and damaged, thereby improving convenience.

[0049] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be regarded as the protection scope of this utility model. The structures, devices and operating methods not specifically described and explained in this utility model shall be implemented according to the conventional means in this field unless otherwise specified and limited.
