Abstract
Description
Technical Field
[0001] This utility model relates to the field of lock technology, and specifically to a lock. Background Technology
[0002] In modern daily life and numerous industries, locks are widely used as essential tools for protecting property and personal privacy. The performance and quality of locks directly impact not only convenience but also security. However, traditional locks exhibit a significant problem in practical application: dust, moisture, and other impurities can easily enter the lock cylinder through the keyhole. For mechanical locks, this can lead to cylinder blockage, affecting normal opening; for electronic locks, it can damage internal electrical components, causing malfunctions, shortening the lock's lifespan, and reducing its reliability.
[0003] To solve this problem, the industry typically uses a keyhole cover. Specifically, a mounting groove is created on the lock directly opposite the keyhole, and then the keyhole cover is used to cover the mounting groove, thus sealing the keyhole and preventing impurities from entering.
[0004] However, this solution has also revealed some new problems in actual use. Because the keyhole cover and the mounting slot are tightly fitted, when users need to open the keyhole cover to unlock the door, it is often difficult to remove the keyhole cover from the mounting slot due to the tight fit, which causes great inconvenience to users and affects the ease of unlocking.
[0005] Furthermore, some users may damage or lose the keyhole cover due to improper operation during installation or removal, further increasing usage costs and maintenance difficulties. For example, after repeated forceful disassembly and reassembly, the keyhole cover of some locks may become loose or unable to close tightly, which not only affects the protective effect of the keyhole but may also affect the overall aesthetics and lifespan of the lock. Utility Model Content
[0006] The primary objective of this invention is to provide a lock that solves at least one of the aforementioned problems.
[0007] To achieve the various objectives of this utility model, the following technical solution is adopted:
[0008] To achieve one of the purposes of this utility model, a lock is provided, including a panel and a cover covering the panel. The cover has a hollow window corresponding to the lock cylinder of the panel and a keyhole cover for covering the hollow window. At the position corresponding to the hollow window, the panel is recessed in a direction away from the cover to form a relief groove. The panel has an abutment platform on the lower side facing away from the relief groove. The side of the keyhole cover facing the panel is connected to an abutment member, which passes through the relief groove and abuts against the abutment platform.
[0009] Furthermore, when the lock hole cover is in the closed state, the abutting member elastically abuts against the abutting platform, causing the abutting member to bend and deform; when the lock hole cover is in the open state, the abutting member separates from the abutting platform, allowing the abutting member to return to its extended state.
[0010] In one embodiment, the panel also has an inner cavity, the abutment platform is disposed in the inner cavity, the bottom of the clearance groove has a through hole communicating with the inner cavity, and the abutment member passes through the through hole and extends into the inner cavity.
[0011] In one embodiment, the abutment platform is inverted and suspended on the top of the inner cavity, and the abutment platform is provided with a sliding surface corresponding to the abutment member, and the abutment member can slide up and down along the sliding surface.
[0012] In one embodiment, the abutment is shaped to arch towards the cover relative to the abutment platform.
[0013] In one embodiment, the end of the abutting member is formed with an abutting portion that abuts against the abutting platform. The size of the abutting portion is larger than the size of the communicating hole to prevent the abutting portion from dislodging from the inner cavity.
[0014] In one embodiment, the bottom wall of the clearance groove transitions in an arc shape from the end furthest from the abutment platform to the end closest to the abutment platform.
[0015] In one embodiment, the abutment is connected to the edge of the keyhole cover.
[0016] In one embodiment, a step is formed on the hollow window, the step is arranged around the circumference of the hollow window, a sealing ring is formed on the edge of the lock hole cover, and the step and the sealing ring are arranged to abut against each other vertically.
[0017] In one embodiment, the shape and size of the keyhole cover are the same as the shape and size of the hollow window.
[0018] Compared with the prior art, this utility model has many advantages, including but not limited to:
[0019] On the one hand, existing keyhole covers fit tightly with the mounting groove, making them difficult for users to open and severely impacting the ease of unlocking. This utility model features a relief groove on the panel corresponding to the hollow window side, and an abutment platform on the lower side of the panel facing away from the relief groove. The keyhole cover connecting abutment piece passes through the relief groove and abuts against the abutment platform. The abutment piece, abutment platform, and relief groove work together to form a seesaw-like structure. Users only need to lightly press one side of the keyhole cover to release the constraint force on the keyhole cover through the elastic deformation of the abutment piece, causing the other side of the keyhole cover to naturally lift up. This breaks through the traditional operation mode of needing to pry open the keyhole cover, significantly reducing the force required to open the cover, making operation effortless and convenient, and significantly improving the user experience, especially in emergency situations where quick unlocking is required.
[0020] On the other hand, the lock hole cover and the panel of this utility model cooperate with each other through abutment parts and abutment platforms to form a stable support, avoiding problems such as loosening or inability to close due to external forces or repeated operations, thus enhancing structural reliability. In addition, it reduces the risk of damage or loss of the lock hole cover, reduces the number of maintenance times and costs, and ensures long-term stable use of the lock, combining practicality and economy.

It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.
[0031] This utility model provides a lock with a lock hole cover corresponding to the lock hole. The lock hole cover can effectively seal the lock hole to prevent external dust, moisture and other impurities from entering the lock through the lock hole. The lock hole cover is also easy for the user to open or close without damaging it.
[0032] In a typical embodiment of this utility model, combined with Figures 1 to 3 The lock 10 includes a panel 100 and a cover 200, with the cover 200 covering the panel 100. The panel 100 includes a body 110 and a lock cylinder 120. One side of the body 110 is a mounting surface 111, and the cover 200 covers the mounting surface 111.
[0033] Combination Figure 3The main body 110 has a mounting hole 112, one opening of which is located on the mounting surface 111. The lock cylinder 120 is installed in the mounting hole 112, and the lock hole 121 of the lock cylinder 120 faces the cover 200. The user can lock or unlock the lock 10 by inserting a key into the lock hole 121.
[0034] Combination Figure 2 and Figure 3 The cover 200 has a hollow window 210, and the cover 200 is placed on the mounting surface 111, so that the hollow window 210 and the mounting surface 111 cooperate to form a sealing groove 130, and the lock cylinder 120 is set opposite to the hollow window 210. It can be understood that the lock hole 121 of the lock cylinder 120 is opened at the bottom of the sealing groove 130.
[0035] The lock 10 also includes a keyhole cover 140, the shape and size of which are the same as those of the hollow window 210. The keyhole cover 140 is installed in the sealing groove 130, and can effectively seal the sealing groove 130 to prevent external dust, moisture and other impurities from entering the lock cylinder 120 through the keyhole 121, thus protecting the lock cylinder from contamination and damage. In this embodiment, the top surface 141 of the keyhole cover 140 and the top surface 220 of the cover 200 are located on the same plane, which not only improves the overall aesthetics of the lock 10, but also makes the lock surface smoother and easier to clean and maintain.
[0036] In one embodiment, combined Figure 4 and Figure 5 A step 211 is formed on the inner side of the hollow window 210, protruding inwards, so that the inner wall of the hollow window 210 and the cross-section of the step 211 form an L-shape. The step 211 continuously surrounds the side wall of the hollow window 210, forming a complete annular structure. Correspondingly, a sealing ring 143 is provided on the edge of the keyhole cover 140. The sealing ring 143 surrounds the edge of the keyhole cover 140 and is made of flexible material, possessing good elasticity and sealing performance.
[0037] When the lock hole cover 140 covers the sealing groove 130, the sealing ring 143 is closer to the bottom of the sealing groove 130 than the step 211, and the sealing ring 143 abuts against the step 211. This cooperation between the sealing ring 143 and the step 211 ensures that the sealing ring 143 effectively seals the sealing groove 130. Specifically, when the lock hole cover 140 is fastened to the sealing groove 130, the sealing ring 143 undergoes elastic deformation due to radial compression from the step 211, causing the sealing ring 143 to fit tightly against the step 211 and press against the side wall of the hollow window 210. This ensures that the sealing ring 143 effectively seals the sealing groove 130 within the hollow window 210, preventing external dust, moisture, and other substances from entering the lock cylinder 120 through the lock hole 121, thus guaranteeing the normal operation and service life of the lock.
[0038] In a typical embodiment of this utility model, combined with Figure 3 The lock hole cover 140 is connected to an abutment 150, which is connected to the bottom surface of the lock hole cover 140. The top surface 141 of the lock hole cover 140 is arranged opposite to the bottom surface of the lock hole cover 140.
[0039] Combination Figure 4 and Figure 5 The main body 110 also includes an inner cavity 160, which is located on one side of the mounting hole 112 and is further away from the cover 200 than the mounting surface 111. An abutment platform 161 is provided within the inner cavity 160. A clearance groove 170 is formed on the bottom of the sealing groove 130, which is also the mounting surface 111, near the inner cavity 160. The clearance groove 170 extends from the mounting surface 111 towards the inner cavity 160. A through hole (referred to as a connecting hole 171) is formed on the bottom of the clearance groove 170, connecting the clearance groove 170 and the inner cavity 160.
[0040] Combination Figure 4The abutment 150 is disposed on the side of the lock hole cover 140 near the relief groove 170. The abutment 150 extends into the inner cavity 160 through the relief groove 170 and the connecting hole 171 in sequence. The end of the abutment 150 that is not connected to the lock hole cover 140 (referred to as the end 151) abuts against the abutment platform 161 in the inner cavity 160. The abutment 150 abuts against the abutment platform 161. The abutment 150 is relatively elastically bent, so that the abutment 150 accumulates elastic support force, so that the abutment 150 can provide support force for the lock hole cover 140, so that the area of the lock hole cover 140 near the relief groove 170 (referred to as the pressing area 144) will not fall into the relief groove 170, thereby allowing the lock hole cover 140 to be stably covered in the sealing groove 130.
[0041] Combination Figure 4 and Figure 6 By applying a force toward the relief groove 170 to the pressing area 144, the pressing area 144 of the lock hole cover 140 falls toward the relief groove 170, and the abutment 150 moves further into the inner cavity 160. The end 151 of the abutment 150 also moves toward the bottom of the inner cavity 160 along the abutment platform 161, so that the abutment 150 is relatively stretched out to release the elastic support force of the abutment 150, thereby so that the abutment 150 no longer provides the support force for the lock hole cover 140.
[0042] The lock hole cover 140 is also provided with a raised area 146, which is located on both sides of the lock hole cover 140, along with the pressing area 144. When the pressing area 144 falls towards the relief groove 170, the raised area 146 rises relative to the pressing area 144, exposing the lock hole 121 of the lock cylinder 120, so that the user can insert the key into the lock hole 121. This allows the user to easily open the lock hole cover 140, greatly reducing the difficulty of opening the lock hole cover 140 and improving the user experience. Furthermore, combined with... Figure 5 Users can also grasp the raised area 146 to further open the keyhole cover 140, making it convenient for users to insert the key into the keyhole 121, thus meeting the user's needs in different situations.
[0043] In one embodiment, combined Figures 4 to 6The abutment platform 161 is provided with a sliding surface 1611, which is arranged along the sliding path of the end 151 of the abutment member 150. The end 151 of the abutment member 150 abuts against the sliding surface 1611, which is used to guide the movement of the end segment. When the end section moves along the sliding surface 1611 toward the relief groove 170, the abutment member 150 continuously increases its elastic bending degree to accumulate elastic support force to support the lock hole cover 140 to be stably covered in the sealing groove 130; when the pressing area 144 is subjected to a force toward the relief groove 170, and the pressing area 144 drives the end section to move toward the sliding surface 1611 toward the bottom of the inner cavity 160, the abutment member 150 continuously releases elastic support force, so that the abutment member 150 continuously stretches and reduces the bending degree, while the raised area 146 is relatively raised, making it easier for the user to open the lock hole cover 140.
[0044] In a further embodiment, the abutment platform 161 is suspended upside down on the top of the inner cavity 160, and the bottom of the abutment platform 161 does not contact the bottom of the inner cavity 160. Figure 6 When the pressing area 144 of the lock hole cover 140 is subjected to a force and descends, the end 151 of the abutment 150 will move along the sliding surface 1611 toward the bottom of the inner cavity 160 and slide below the sliding surface 1611, so as to further extend the abutment 150 and prevent the abutment 150 from providing support for the lock hole cover 140, making it easier to further open the lock hole cover 140.
[0045] In one embodiment, combined Figures 3 to 6 An abutment portion 152 is formed on the end 151 of the abutment member 150. The abutment portion 152 abuts against the sliding surface 1611 of the abutment platform 161. The abutment portion 152 facilitates contact with the sliding surface 1611. When not subjected to external force, the abutment portion 152 will not slide along the sliding surface 1611, thereby improving the structural stability of the lock hole cover 140. In one embodiment, the abutment portion 152 is a protruding structure to enhance its contact effect and stability with the sliding surface 1611.
[0046] Combination Figure 3 and Figure 5The size of the abutment portion 152 is larger than the size of the connecting hole 171, meaning that the abutment portion 152 cannot be dislodged from the inner cavity 160 through the connecting hole 171. Even when the lock hole cover 140 is not constrained by the sealing groove 130, such as when the lock hole cover 140 is dislodged from the sealing groove 130 or is not properly installed, the connecting hole 171 will still effectively constrain the abutment portion 152, limiting the range of movement of the lock hole cover 140. This ensures that the lock hole cover 140 will not fall off the lock 10; that is, the lock hole cover 140 can always be hung on the lock 10, effectively preventing the loss of the lock hole cover 140 and providing greater convenience and security for the user.
[0047] In one embodiment, the abutment 150 is a sheet-like structure to facilitate elastic bending and provide elastic support. Furthermore, the abutment 150 is also an arched structure, arching towards the cover 200, so that when it abuts against the abutment platform 161, the abutment 150 can further elastically bend along its arching direction, i.e., arch, to enhance the elastic support.
[0048] In one embodiment, combined Figure 3 The bottom wall 172 of the clearance groove 170 transitions in an arc shape from the end furthest from the inner cavity 160 (first end 1721) to the end closest to the inner cavity 160 (second end 1722), forming a continuous arc structure. When the pressing area 144 of the lock hole cover 140 is pressed and descends, the pressing area 144 is guided by the arc shape of the bottom wall 172 of the clearance groove 170, thus achieving a slow and smooth descent. This effectively prevents the pressing area 144 from descending too far, preventing damage to the lock hole cover 140 due to excessive pressing, and also helps improve user operating comfort and the overall performance of the lock.
[0049] In summary, this lock design allows users to easily press the keyhole cover, causing one end to lower and the other to rise, thus conveniently opening the cover and exposing the lock cylinder. This not only reduces the difficulty of opening the keyhole cover and significantly improves the user experience, but also ensures the sealing performance and reliability of the keyhole cover, effectively protecting the lock cylinder from external environmental factors, extending the lock's service life, and possessing high practical value and market competitiveness.
