It mainly includes an access control block installed on the door lock, which is provided with an access control card slot for inserting an access control card to unlock the door. The access control block is provided with a sliding groove, and a set of symmetrical elastic blocks are movably connected in the sliding groove. The two sets of elastic blocks block the access control card slot under the influence of their own elasticity in the free state. The elastic blocks can be separated by extrusion force. The unused access control card slot is sealed by the set of symmetrical elastic blocks, thereby completing the sealing function of the access control card slot.

[0004] However, the use of the elastic block form will cause the elastic body of the elastic block below to deform under the action of gravity for a long time, resulting in excessive drop of the seal, and the use of the elastic block form will cause greater wear on both sides of the access control card.

[0024] Example 1, combined with Figure 1 、 Figure 2 and Figure 3 To explain:

[0025] A door access card slot protection structure includes: a base 1, a card slot seat 2, a rear fixing seat 3, a card sensing elastic slider assembly 4, an electromagnet 5, an electromagnet control switch 6, a junction box 7, a sealed slider 8 and an iron plate 9. The card slot seat 2 and the rear fixing seat 3 are fixed to the base 1 by screws, and the rear fixing seat 3 is arranged on the rear side of the card slot seat 2, which facilitates the arrangement and installation of the card sensing elastic slider assembly 4, the electromagnet 5, the electromagnet control switch 6, the junction box 7, the sealed slider 8 and the iron plate 9.

[0026] The card slot seat 2 is provided with a card slot, and the card sensing elastic slider assembly 4 is slidably arranged in a sliding groove in the card slot. The card sensing elastic slider assembly 4 is used to sense the access card for entry.

[0027] The lower side of the card sensing elastic slider assembly 4 is fitted with the electromagnet control switch 6 , and the card sensing elastic slider assembly 4 can trigger the electromagnet control switch 6 .

[0028] The electromagnet control switch 6 is set on the junction box 7 and electrically connected to the junction box 7. The sealed slider 8 is set on the rear side of the card sensing elastic slider assembly 4. The sealed slider 8 is vertically slidably connected to the card slot seat 2 and the rear fixed seat 3. The sealed slider 8 can completely close the card slot.

[0029] The electromagnet 5 is fixedly connected to the sealed slider 8, and the electromagnet 5 is used to drive the sealed slider 8 to move.

[0030] The electromagnet 5 is electrically connected to the junction box 7 . An iron plate 9 is provided above the electromagnet 5 and is fixedly mounted on the upper surface of the slot.

[0031] The iron plate 9 is used to cooperate with the electromagnet 5 so that when the electromagnet 5 is energized, the electromagnet 5 can move toward the iron plate 9 and be adsorbed.

[0032] The cross section of the sealed slider 8 is the same as that of the slot, which improves the sealing performance and ensures the sealing effect.

[0033] The rear fixing seat 3 is provided with a detection slot, which is concentric with the card slot.

[0034] By setting the electromagnet 5 and the iron plate 9 to attract each other, they can be used for a long time without damage or deformation, ensuring the sealing during use. The card sensing elastic slider assembly 4 will only cause slight wear on one side of the access card. The wear surface can be selectively set on the side opposite to the magnetic piece, thereby effectively protecting the magnetic piece on the access card and increasing the service life of the access card.

[0035] Example 2, based on Example 1, combined with Figure 4 To explain:

[0036] The card sensing elastic slider assembly 4 includes: a wedge-shaped slider 41, a sliding block 42, a limit plate 43 and a spring 44. The wedge-shaped slider 41 is fixedly set on the sliding block 42, and limit plates 43 are set on both sides of the sliding block 42. The sliding block 42 is slidably connected to the sliding groove. The bottom of the sliding block 42 is fitted with the electromagnet control switch 6. The spring 44 is set between the limit plate 43 and the sliding groove. The wedge-shaped slider 41 is used in conjunction with the access card.

[0037] The upper surface of the wedge-shaped slider 41 is an inclined surface inclined toward the outside of the slot.

[0038] The extended height of the wedge-shaped slider 41 is the same as the stroke of the electromagnet control switch 6 .

[0039] When in use, the wedge-shaped slider 41 moves downward under the action of the access card, thereby driving the sliding block 42 to move downward, triggering the electromagnet control switch 6, and the limit plate 43 and spring 44 play the role of limiting and resetting.

[0040] The working principle of the present invention is as follows: when the device is in use, the access card is inserted into the card slot, and the access card will squeeze the wedge-shaped slider 41 downward to turn off the electromagnet control switch 6, thereby cutting off the power to the electromagnet 5, and the magnetism of the electromagnet 5 and the iron plate 9 disappears. The closed slider 8 slides downward under the action of gravity, thereby connecting the card slot and the detection card slot. The access card continues to be inserted forward into the detection card slot for identification. After the identification is completed, the access card is taken out, and the wedge-shaped slider 41 is reset under the action of the spring 44. The electromagnet control switch 6 is turned on, and the electromagnet 5 is electrically connected to generate magnetism. The electromagnet 5 is upwardly adsorbed with the iron plate 9 to drive the closed slider 8 to move upward to close the card slot. The utility model has a reasonable structure and is easy to use. It can ensure the sealing of the access card slot during use and can increase the service life of the access card.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, all changes that come within the meaning and range of equivalents of the claims are intended to be embraced by the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements and improvements made to the above embodiments based on the technical essence of the present invention should be included in the scope of protection of the technical solution of the present invention.
