[0019] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments: Figures 1-6 A lock with a dustproof device includes a lock body 1, on which a lock hole 2 is provided. The lock hole 2 is used to control the position of an anti-pry block to achieve further locking or unlocking.

[0020] Generally, the keyhole 2 is exposed. After a long period of dust accumulation, the keyhole 2 may become unable to be opened due to impurities. Especially in some working environments with a lot of dust, extra attention should be paid to the condition of the keyhole 2.

[0021] To this end, the outer side of the lock body 1 is generally provided with several panels 3. The panels 3 are mounted on the door panel and protrude from the lock hole 2. Several dustproof plates 5 are provided in the panels 3. The dustproof plates 5 are moved to achieve a dustproof state. A through hole 4 is provided on the panel, and the lock hole 2 is set in the through hole 4.

[0022] Specifically, there are two groups of panels 3, which are arranged on both sides of the lock body. Two dustproof plates 5 are provided on the rod of each panel 3. When the dustproof plates 5 are against each other, the lock hole 2 is sealed, reducing the possibility of impurities entering the lock hole 2 to achieve dustproofing.

[0023] At the same time, in order to facilitate the control of the position of the dustproof plate 5, a control component is set in the panel 3, and the control component includes two control panels 6. The control panels 6 are located on the outside of the dustproof plate 5. At the same time, after the control panels 6 move toward each other, the dustproof plate 5 moves in the opposite direction, so that the lock hole 2 is exposed and the key can be inserted normally.

[0024] Specifically, adjacent first slide grooves 7 and second slide grooves 8 are provided in the door panel, wherein the first slide groove 7 is used for sliding of the dustproof plate 5, and the second slide groove is used for sliding of the control plate 6, wherein the dustproof plate 5 is connected to the bottom surface of the first slide groove 7 through a plurality of springs 9.

[0025] Furthermore, the ends of the dustproof plates 5 that do not touch each other are connected to the corresponding ends of the control panels 6 via a connecting rope 10. The connecting rope 10 passes through the spring 9 to connect the dustproof plates 5 and the control panels 6. Consequently, when the control panels 6 move toward each other, the dustproof plates 5 overcome the movement of the spring 9 under the action of the connecting rope 10, achieving opposite movement of the two sets of dustproof plates 5, exposing the lock hole 2. At the same time, to facilitate the operation of the connecting rope 10, a rotating member is provided at the tail end of the first chute 7 and the second chute 8. The connecting rope 10 connects the control panel 6 and the dustproof plates 5 via the rotating member. In this embodiment, the rotating member is a pulley.

[0026] At the same time, in order to control the movement of the control plate 6, a magnetic area 12 is provided on the opposite end of the control plate 6. Specifically, the magnetic area 12 can cover the side of the control plate 6 and can be fixed there by adhesion. When a magnetically adsorbable key is placed between the control plate 6, the control plates 6 are connected toward each other, thereby opening the dustproof plate 5 and allowing the key to enter the lock hole 2. Generally speaking, the key can be made of nickel-copper alloy and can be adsorbed by the magnetic area 12.

[0027] Furthermore, in order to prevent the key from being stuck in the dustproof plate 5 and difficult to move, a card block 11 is provided in the second slide groove 8. In this embodiment, card blocks 11 are provided on both the upper and lower sides of the second slide groove 8. The control panel 6 is limited in front of the card block 11 when it moves, so that the control panel 6 avoids direct contact with the key and limits the key.

[0028] Furthermore, the sealing between the dustproof plates 5 is enhanced. The dustproof plates 5 include a first dustproof plate 5 and a second dustproof plate 5, wherein the first dustproof plate 5 includes a groove 13, and the second dustproof plate 5 is provided with a protrusion 14 for matching the groove 13. The combination of the groove 13 and the protrusion 14 can achieve better sealing for dust prevention, and a sealing layer 15 is laid on the groove 13 or the protrusion 14. The sealing layer 15 is made of rubber material, and in this embodiment, the sealing layer 15 is provided in the groove 13. When the protrusion 14 enters the groove 13, the dustproof plates 5 are stably sealed.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
