Description

Technical Field

[0001] This utility model relates to the field of locks, and more particularly to a mobile shelving lock with enhanced torque. Background Technology

[0002] Mobile shelving units, also known as mobile shelving units, are used in Japan due to its small land area, saving over 70% of space. They offer large storage capacity, ease of use, space saving, and convenient management, making them the preferred choice for government departments and large enterprises for data storage. For data confidentiality, locks are typically installed on the mobile shelving units to prevent data leakage.

[0003] In existing technologies, mechanical locks are typically used to lock the locking plate. At the same time, the rotation of the locking plate is controlled by a handle. That is, after the mechanical lock is unlocked, the handle is operated to rotate the locking plate, thereby turning the locking plate off the external moving object such as a cabinet door, thus achieving unlocking.

[0004] To prevent the lock plate from rotating endlessly during operation, a stop mechanism is installed to limit its rotation angle. However, different users apply varying degrees of force when turning the handle; excessive torque can cause excessive torque on the lock plate, damaging the stop mechanism. Utility Model Content

[0005] In order to solve the above-mentioned problems in the prior art, this utility model provides a mobile shelving lock with enhanced torque.

[0006] The above-mentioned problems of this utility model are solved by the following technical solution:

[0007] A torque-enhancing mobile shelving lock, comprising,

[0008] A housing that is mounted on a fixed object, the housing having connection holes;

[0009] The drive sleeve is movably disposed within the connection hole and can rotate around the rotation axis within the connection hole.

[0010] A locking plate is fixedly disposed at the tail of the drive sleeve. The locking plate has a locking position that extends relative to the outer shell and a releasing position that rotates back to the back of the outer shell.

[0011] The locking plate has a protrusion on the side facing the outer shell. The protrusion moves synchronously with the locking plate and forms an arc-shaped movement path around the rotation axis on the rear side of the outer shell.

[0012] The back of the housing is provided with a stop structure that limits the movement range of the protrusion, and the protrusion and the stop structure form surface contact at the stop position.

[0013] By adopting the above technical solution, the contact position between the protrusion and the stop structure is set to surface contact, thereby reducing the torsional force on each contact point and thus avoiding damage to the stop structure caused by excessive torque.

[0014] A further provision of the above technical solution is that the stop structure shown is disposed on the moving path of the protrusion, and the stop surface is located on the radial line of the moving path.

[0015] A further provision of the above technical solution is that the stop structure is a stop block, and the side of the stop block facing the protrusion is a stop surface.

[0016] A further provision of the above technical solution is that: two stop blocks are provided, and they are located on both sides of the protrusion moving path;

[0017] The two stop surfaces are set opposite each other.

[0018] A further provision of the above technical solution is that the thickness of the stop block along the radial line is at least able to cover the thickness of the protrusion.

[0019] By adopting the above technical solution, the stop surface can completely cover the contact end surface of the protrusion, and can fully bear the torque of the protrusion and decompose the torsional force, thereby ensuring that the torque on the protrusion can be maximized as much as possible.

[0020] A further provision of the above technical solution is that the protrusion is a bent rib formed on the locking plate.

[0021] A further provision of the above technical solution is that the head of the drive sleeve is formed with a handle, and the outer shell is provided with a handle groove that can accommodate the rotation of the handle.

[0022] A further feature of the above technical solution is that it also includes a lock cylinder, which is disposed through the outer shell and has a locked state and an unlocked state with the outer shell through a blade;

[0023] The lock cylinder is positioned close to the lock plate and is capable of locking the lock plate.

[0024] A further provision of the above technical solution is that the lock cylinder is at least partially exposed to the back of the outer casing to form a locking part and an unlocking part;

[0025] The locking part and the unlocking part are on the same circumference, and at least part of them are on the same plane as the locking piece;

[0026] When the locking part faces the locking plate, the locking plate is provided with a locking groove that can cooperate with the locking part.

[0027] A further provision of the above technical solution is that the locking part is a protrusion formed at the tail of the lock cylinder and rotates synchronously with the lock cylinder.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a protrusion on the lock plate and a stop structure on the back of the outer shell, the protrusion and the stop structure form a surface contact at the stop position. Compared with traditional point contact or line contact, surface contact can reduce the torsional force per unit area, avoid damage to the stop structure caused by excessive torque, thereby enhancing the torsional force that the stop structure can withstand and extending the service life of the lock.

[0043] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0044] like Figure 1-8 As shown, this embodiment discloses a mobile shelving lock with enhanced torque.

[0045] A torque-enhancing mobile shelving lock, comprising,

[0046] A housing 100 is mounted on a fixed object, and the housing 100 is provided with a connection hole 101;

[0047] The drive sleeve 200 is movably disposed within the connection hole 101 and can rotate around the rotation axis L within the connection hole 101.

[0048] The locking plate 300 is fixedly disposed at the tail of the drive sleeve 200. The locking plate 300 has a locking position that extends relative to the outer shell 100 and an unlocking position that rotates back to the back of the outer shell 100 through the drive sleeve 200.

[0049] A protrusion 310 is provided on the locking plate 300 facing the outer shell 100. The protrusion 310 moves synchronously with the locking plate 300 and forms an arc-shaped movement path around the rotation axis L on the rear side of the outer shell 100.

[0050] The back of the housing 100 is provided with a stop structure that limits the movement range of the protrusion 310, and the protrusion 310 forms surface contact with the stop structure at the stop position.

[0051] The above is the basic scheme of this embodiment.

[0052] Specific reference Figure 1 and Figure 2 As shown, after the locking plate 300 is unlocked, the user drives the drive sleeve 200. The drive sleeve 200 rotates around the rotation axis L in the connection hole 101. During the rotation, it drives the locking plate 300 at the tail to rotate, thereby causing the locking plate 300 to rotate from the locked position back to the unlocked position.

[0053] A locking tongue 320 extends from the locking plate 300. When in the locked position, the locking tongue 320 extends to the side of the outer casing 100 and locks with the outer cabinet door. When in the unlocked position, the locking tongue 320 retracts back to the back of the outer casing 100 and separates from the cabinet door.

[0054] To facilitate user operation, in this embodiment, the head of the drive sleeve 200 is formed with a handle 210, and the outer shell 100 is provided with a handle 210 groove 102 that can accommodate the rotation of the handle 210.

[0055] In other embodiments, the position of the latch 320 is not restricted by the outer casing 100, and the latch 320 can stop the moving cabinet door in the locked position.

[0056] In this embodiment, the rotation axis L is the center line of the drive sleeve 200 or the connecting hole 101.

[0057] When the user rotates the handle 210, the drive sleeve 200 rotates synchronously, thereby unlocking the lock plate 300.

[0058] During the rotation of the locking plate 300, the protrusion 310 on the locking plate 300 rotates synchronously with the locking plate 300, and the movement path is an arc formed around the rotation axis L. In order to limit the rotation angle of the locking plate 300, a stop structure is provided on the back of the outer shell 100 in this embodiment. The protrusion 310 rotates within the stop structure, thereby limiting the movement path of the protrusion 310 and thus limiting the rotation angle of the locking plate 300.

[0059] When the locking plate 300 is subjected to a large torsional force, the protrusion 310 exerts a large pushing force on the stop structure. In this embodiment, the contact position between the protrusion 310 and the stop structure is set to surface contact, thereby reducing the torsional force on each contact point and thus avoiding damage to the stop structure caused by excessive torque.

[0060] Specifically, in this embodiment, the stop structure shown is disposed on the moving path of the protrusion 310, and the stop surface 401 is located on the radial line of the moving path.

[0061] Specific reference Figure 3 and Figure 4 As shown, during the rotation of the protrusion 310, the two end faces along the rotation path direction are always on the radial line of the moving path. Therefore, in order to match the two contact end faces of the protrusion 310 and make the protrusion 310 form a surface contact at the two ends of the moving path, the two stop surfaces 401 on the stop structure are also set on the radial line of the moving path. That is to say, during the rotation of the locking piece 300, the two contact end faces on the protrusion 310 are always on the radial line of the moving path. Thus, when the protrusion 310 rotates to the two ends of the moving path, it forms a surface contact with the two stop surfaces 401 of the stop structure.

[0062] Compared to point contact or line contact, the pushing force per unit area formed by the protrusion 310 on the stop structure is smaller when there is surface contact. This avoids damage to the stop structure due to excessive pushing force from the protrusion 310, thereby increasing the torque that the stop structure can bear.

[0063] Specifically, the stop structure is a stop block 400, and the side of the stop block 400 facing the protrusion 310 is a stop surface 401.

[0064] Specific reference Figure 5 As shown, the stop block 400 is a block structure, and it only needs to be on the radial line of the moving path.

[0065] Preferably, in this embodiment, the stop block 400 is configured as a right-angled trapezoidal structure, with the right angle located on the side connecting the stop surface 401, and the end face opposite to the stop surface 401 is configured as an inclined surface.

[0066] Compared to a vertical surface, the inclined structure creates a triangular support structure on one side of the stop block 400, which further increases the torsional force that the stop block 400 can withstand.

[0067] The stop block 400 is formed on the back of the housing 100, and in order to reduce the contact between the stop block 400 and the locking plate 300 and reduce the friction force that the locking plate 300 needs to overcome when rotating, the thickness of the stop block 400 is less than the gap between the locking plate 300 and the housing, that is, there is a gap between the stop block 400 and the locking plate 300.

[0068] Furthermore, in order to limit the position of the protrusion 310 in both directions, two stop blocks 400 are provided in this embodiment, and they are located on both sides of the movement path of the protrusion 310.

[0069] The two stop surfaces 401 are set opposite each other.

[0070] The angle formed between the two stop surfaces 401 and the rotation axis L is the rotation angle of the locking piece 300. In this embodiment, the rotation angle is preferably 50°.

[0071] Furthermore, in this embodiment, the thickness of the stop block 400 along the radial line is at least sufficient to cover the thickness of the protrusion 310.

[0072] With this configuration, the stop surface 401 can completely cover the contact end surface of the protrusion 310, which can fully bear the torque of the protrusion 310 and decompose the torsional force, thereby ensuring that the torque on the protrusion 310 can be maximized as much as possible.

[0073] Specifically, in this embodiment, the protrusion 310 is a bent rib formed on the locking piece 300.

[0074] Preferably, in this embodiment, a bent piece is cut out on the locking piece 300, with only one side connected, and the bent piece is bent toward the outer shell to form the protrusion 310.

[0075] In this embodiment, the locking method of the locking plate 300 is specifically set as follows: it also includes a lock cylinder 500, which is disposed through the outer shell 100 and has a locking state and an unlocking state with the outer shell 100 through the blade;

[0076] The lock cylinder 500 is positioned close to the lock plate 300 and is capable of locking the lock plate 300.

[0077] The locking structure of the lock cylinder 500 and the outer shell in this embodiment is the same as that of the lock cylinder 500 locked by the blade in the prior art, and will not be described in detail here.

[0078] Lock cylinder 500 is unlocked by key. Turning lock cylinder 500 puts it in the unlocked state. At this time, lock plate 300 is separated from lock cylinder 500. The user can then drive lock plate 300 by turning handle 210, thereby unlocking the bolt 320 from external moving objects.

[0079] To lock, first rotate the lock plate 300 to the position where it locks with the moving object, then rotate the lock cylinder 500 to lock the lock plate 300. Finally, use the key to lock the lock cylinder 500 and the outer shell to complete the locking of the lock plate 300.

[0080] Specifically, the lock cylinder 500 is at least partially exposed to the back of the housing to form a locking part 510 and an unlocking part 501;

[0081] The locking part 510 and the unlocking part 501 are on the same circumference, and at least part of them are on the same plane as the locking piece 300;

[0082] When the locking part 510 faces the locking plate 300, the locking plate 300 is provided with a locking groove 301 that can cooperate with the locking part 510.

[0083] Specific reference Figure 7 and Figure 8 As shown, both the locking part 510 and the unlocking part 501 are located at the tail of the lock cylinder 500 and protrude to the rear side of the outer casing 100. After the lock cylinder 500 is unlocked by the key and the outer casing, rotating the lock cylinder 500 unlocks the unlocking part 501 and the lock plate 300. At this time, the lock plate 300 can be driven to rotate. In the locked state, the locking part 510 on the lock cylinder 500 faces the lock plate 300. The lock plate 300 has a recess forming a lock groove 301, and the recess matches the shape of the locking part 510. When the locking part 510 faces the lock plate 300, it is engaged in the lock groove 301. At this time, due to the blocking effect of the locking part 510, the lock plate 300 cannot be rotated, so the lock plate 300 cannot be unlocked.

[0084] Specifically, the locking part 510 is a protrusion formed at the tail of the lock cylinder 500 and rotates synchronously with the lock cylinder 500.

[0085] Specific reference Figure 6 As shown, a protrusion is formed at the tail of the lock cylinder 500, which rotates synchronously with the lock cylinder 500; and the opposite side of the locking part 510 is provided as the unlocking part 501. When the unlocking part 501 rotates to the side facing the lock plate 300, a space is formed between it and the lock groove 301. That is to say, the unlocking part 501 cannot be locked into the lock groove 301 to lock the lock plate 300.

[0086] When the locking part 510 rotates to the side of the locking piece 300, it can be engaged in the locking groove 301 and cooperate with the locking groove 301 to lock the locking piece 300.

[0087] Preferably, in this embodiment, the locking part 510 is a column with the same shape as the lock cylinder 500, and the outer diameter of the column is the same as that of the lock cylinder 500; the unlocking part 501 is a gap located on the opposite side of the locking part 510.

[0088] In other embodiments, the locking part 510 and the unlocking part 501 may also be other structures, as long as the locking part 510 can be engaged in the locking groove 301 of the lock piece 300, and the unlocking part 501 cannot be engaged in the locking groove 301 and does not obstruct the lock piece 300.

[0089] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
