Description
Technical Field
[0001] The present invention relates to the technical field of padlocks, and particularly to a stainless steel padlock that can avoid involuntary unlocking caused by accidental touching of the lock core and has a simple structure. Background Art
[0002] Padlocks are often used in fields such as suitcases, storage lockers, luggage, door handles, etc. A traditional typical padlock generally consists of components such as a lock body, a U-shaped lock hook, a lock core, and a key. Among them, the lock body is generally in a rectangular structure and a lock core is arranged inside. The U-shaped lock hook is installed at one end of the lock body, and a keyhole is provided at the other end of the lock body. When the correct key is inserted into the keyhole, the lock core can be rotated to disengage the locking mechanism from the U-shaped lock hook, thereby allowing the U-shaped lock hook to slide out of the lock body. When the short leg of the U-shaped lock hook is completely removed from the lock body or separated from the lock body to be in the unlocked state, the padlock is allowed to be removed from the buckle of the suitcase to be locked or other such components or hung on the component to be locked.
[0003] However, generally one end of the lock core of the existing padlock is exposed outside the lock body so that the key can be directly inserted into the lock core. However, with this structural arrangement, it is easy to accidentally touch the lock core and cause it to rotate and unlock, resulting in involuntary unlocking, thereby affecting the use safety and user experience. In order to prevent accidentally touching the lock core and causing it to rotate and unlock and to enhance the encryption function of the padlock, usually an encryption side (complex tooth pattern) is provided on the surface of the key, and various encryption pins or thrust pins are added inside the lock body, and various auxiliary springs are provided. However, the setting of the encryption side makes the production process extremely complex, requires a large number of accessories, has too high a cost, and is not conducive to commercial promotion and application. In addition, in the unlocked state of the existing padlock, the key cannot be held, and the key is easy to fall off from the lock body, thereby resulting in inconvenient use and easy loss of the key.
[0004] Therefore, it is necessary to provide a stainless steel padlock that can avoid involuntary unlocking caused by accidental touching of the lock core and can hold the key in the unlocked state to prevent it from falling off to solve the above technical problems. Summary of the Invention
[0005] The purpose of the present invention is to provide a stainless steel padlock that can avoid involuntary unlocking caused by accidental touching of the lock core and can hold the key in the unlocked state to prevent it from falling off.
[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a stainless steel padlock is provided, comprising a lock body, a lock core rotatably installed in the lock body, and a lock hook movably installed on the lock body, the stainless steel padlock also comprising a lock core sub-component and a key; wherein the lock core sub-component is fixed in the lock body and docked with the lock core, a hollow channel and a sub-component groove are provided on the lock core sub-component, the hollow channel extends along the axial direction of the lock core sub-component and passes through both ends thereof, and the sub-component groove extends along the radial direction of the lock core sub-component and connects with the hollow channel; a protrusion is convexly provided on the surface of the key, and the protrusion can be slidably matched with the sub-component groove, so that the key can slide along the hollow channel and the sub-component groove to enter and exit the lock core.
[0007] Preferably, the lock core is provided with a lock core inner cavity, which extends along the axial direction of the lock core and passes through one end of the lock core close to the lock core sub-component to communicate with the hollow channel, and the key is detachably inserted into the lock core inner cavity and can drive the lock core to rotate. In the process of the key passing through the lock core sub-component to drive the lock core to rotate, the lock core sub-component will not rotate with it because it is fixedly connected to the lock body. In this way, touching the lock core sub-component at any time will not cause the lock core to rotate, thereby effectively avoiding unintentional unlocking and improving the user experience.
[0008] Preferably, a lock core groove is further provided on the lock core, and the lock core groove extends along the radial direction of the lock core and is connected to the inner cavity of the lock core. When the lock core rotates, the lock core groove and the auxiliary component groove can be correspondingly connected or misaligned. When the lock core groove and the auxiliary component groove are correspondingly connected, the protrusion can slide along the two. When the lock core groove and the auxiliary component groove are misaligned, the protrusion abuts against the inner end surface of the lock core auxiliary component. In this way, only when the lock core is in the locked position and the lock core groove and the auxiliary component groove on it correspond to and are connected, can the protrusion slide along the two, and can the key be inserted into the lock core to drive the lock core to rotate to unlock or slide away from the lock core. When the lock core rotates to the unlocking position, the lock core groove and the auxiliary component groove are staggered. At this time, the protrusion just abuts against the inner end surface of the lock core auxiliary component, preventing the key from moving along the axial direction of the lock core, achieving the purpose of jamming the key, and preventing the key from accidentally falling from the lock body. At this time, even if the key is subjected to an outward pulling force, the protrusion abuts against the lock core auxiliary component to prevent the key from being pulled out, so that the key is always kept on the lock body, improving the user experience. Only after the lock core is rotated and locked again, can the protrusion be moved to the position corresponding to the auxiliary component groove, and at this time, the protrusion can slide along the auxiliary component groove to remove the key.
[0009] Preferably, a positioning post protrudes from the inner end surface of the inner cavity of the lock core; an end face concave hole corresponding to the positioning post is formed on the end face of the key. When the key is inserted into the inner cavity of the lock core, the positioning post is inserted into the end face concave hole, thereby realizing the firm connection between the key and the lock core and enabling the key to drive the lock core to rotate.
[0010] Preferably, the positioning post is integrally formed with the lock core.
[0011] Preferably, a connection hole is formed on the inner end surface of the inner cavity of the lock core. One end of the positioning post is inserted into the connection hole and is tightly fitted with the lock core, thereby making the installation of the positioning post more convenient.
[0012] Preferably, the key includes a connected key body and a key handle. The convex block protrudes from the surface of the key body. The end face concave hole is formed at the end of the key body and extends along its axial direction. The key body is detachably inserted into the lock core and can drive the lock core to rotate. The key handle is located outside the lock body for the user to operate.
[0013] Preferably, a lock core stopper and a hook portion are further provided at one end of the lock core away from the lock core accessory. The lock core stopper and the hook portion are arranged at intervals with a height difference. By rotating the lock core, the hook portion and the lock core stopper can respectively abut against the lock hook, thereby holding the lock hook in the locked position or the unlocked position.
[0014] Preferably, the hook portion is formed by extending downward from one end of the lock core stopper. When the end of the hook portion away from the lock core stopper abuts against the lock hook, the lock hook is held in the locked position. When the lock core rotates and the hook portion disengages from the locking end face of the lock, the lock hook can move upward to abut against the lower end face of the lock core stopper, thereby holding the lock hook in the unlocked position.
[0015] Preferably, the lock core stopper has an upper end face and a lower end face arranged oppositely. When the lock hook is in the unlocked position, the lock hook abuts against the lower end face of the lock core stopper. When the lock hook is driven by an external force to move downward, it can push the upper end face of the lock core stopper to drive the lock core to rotate to the locked position.
[0016] Preferably, an abutting platform is further provided on the side wall of the lock core. The abutting platform is arranged deviating from the axis line of the lock core. When the abutting platform is stressed, the lock core can be rotated along its axis line to the locked position.
[0017] Preferably, the stainless steel padlock further includes a sleeve assembly which is movably disposed in the lock body and always abuts against the abutting platform, and the lock core is stably held in the locked position or the unlocked position by the acting force provided by the sleeve assembly.
[0018] Preferably, the sleeve assembly at least includes a sleeve and a first elastic member installed in the sleeve. The sleeve is movably installed in the lock body and corresponds to the abutting platform. The elastic force of the first elastic member makes the sleeve always abut against the abutting platform to stably hold the lock core in the locked position or the unlocked position.
[0019] Preferably, the sleeve assembly further includes a plug cap and a positioning projection protruding from the plug cap. One end of the first elastic member away from the sleeve is sleeved on the positioning projection and abuts against the plug cap. The first elastic member is positioned by the plug cap and the positioning projection, so that the first elastic member is not easily deflected when being extruded and deformed due to the rotation of the lock core.
[0020] Preferably, the lock hook includes a lock hook long rod and a lock hook short rod. The lock hook long rod is movably installed in the lock body, and a clamping platform is provided at the end of the lock hook long rod. The lock hook can be held in the locked position or the unlocked position by the abutment of the clamping platform and the lock core, so that the lock hook short rod is inserted into or disengaged from the lock hole on the lock body.
[0021] Preferably, the clamping platform abuts against the hook portion and the lock core stopper of the lock core respectively, so as to hold the lock hook in the locked position and the unlocked position.
[0022] Preferably, a bottom groove is further provided at the bottom of the lock hook long rod, and a second elastic member is arranged in the bottom groove. The elastic force provided by the second elastic member makes the lock hook long rod always tend to move towards the unlocked position. The elastic force of the second elastic member is prevented from ejecting the lock hook long rod out of the lock body by the abutment of the clamping platform and the hook portion and the lock core stopper of the lock core.
[0023] Preferably, a pushing surface is further provided at the end of the lock hook long rod, and the pushing surface is arranged above the clamping platform. When the clamping platform abuts against the lower end surface of the lock core stopper, the pushing surface abuts against the upper end surface of the lock core stopper. When the lock hook is moved downward by an external force, the upper end surface of the lock core stopper is pushed by the pushing surface to drive the lock core to rotate towards the locked position.
[0024] Preferably, an installation hole and a lock hole are provided at intervals on the lock body. The lock hook long rod is movably installed in the installation hole, and the lock hook short rod is inserted into or disengaged from the lock hole by the movement of the lock hook long rod.
[0025] Preferably, a main body groove is recessed in the end face of the lock body for installing the lock hook. A sleeve through-hole communicating with the interior of the lock body is formed in the main body groove. The sleeve assembly is installed in the sleeve through-hole, making the installation of the sleeve assembly more convenient.
[0026] Preferably, the stainless steel padlock further includes a main body cover plate. The shape of the main body cover plate corresponds to that of the main body groove. The main body cover plate is detachably installed in the main body groove.
[0027] Preferably, the main body cover plate and the main body groove are detachably connected through matching positioning posts and positioning holes.
[0028] Preferably, when the main body cover plate covers the main body groove, it is flush with the end face of the lock body.
[0029] Compared with the prior art, the stainless steel padlock of the present invention has the following technical effects:
[0030] 1. A lock core sub-component is added. The lock core sub-component is fixed in the lock body and docked with the lock core. The key can drive the lock core to rotate only after passing through the lock core sub-component. Moreover, during the process of the key driving the lock core to rotate, the lock core sub-component remains stationary. During use, even when the key is pulled out, if a person touches the lock core sub-component, the lock core will not rotate. Compared with the prior art, it can effectively avoid the situation where the lock core rotates due to accidental human touch of the lock core, thereby effectively avoiding unlocking against the subjective will, improving the locking security and enhancing the user experience.
[0031] 2. A hollow channel and a sub-component groove are formed in the lock core sub-component. The hollow channel extends along the axial direction of the lock core sub-component and penetrates both ends thereof. The sub-component groove extends along the radial direction of the lock core sub-component and communicates with the hollow channel. Secondly, a convex block is provided on the surface of the key. The convex block can be slidably matched with the sub-component groove, so that the key can slide in and out of the lock core along the hollow channel and the sub-component groove. In this way, when the key drives the lock core to rotate to the unlocking position, the convex block just abuts against the inner end face of the lock core sub-component, preventing the key from moving axially along the lock core and achieving the purpose of clamping the key. It can prevent the key from accidentally falling out of the lock body. At this time, even if the key is subjected to an outward pulling force, the convex block thereon can abut against the lock core sub-component to prevent the key from being pulled out, so that the key is always held on the lock body, enhancing the user experience.
[0032] 3. The traditional encrypted side structure is cancelled on the outer surface of the key. Only convex blocks are provided on the surface of the key, simplifying both the key and the internal structure of the lock body, reducing the number of accessories, further simplifying the production process, reducing the production cost, and being more conducive to commercial promotion and application.

[0051] Now, embodiments of the present invention will be described with reference to the accompanying drawings, in which like reference numerals represent like elements. It should be noted that the orientation descriptions involved in the present invention, such as up, down, left, right, front, back, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the technical solutions of the present application or / and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. The first, second, etc. described are only used to distinguish technical features, and should not be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence of the indicated technical features.
[0052] Combined with Figures 1 - 18 As shown, the stainless steel padlock 100 provided by the present invention is particularly applicable to luggage, lockers, suitcases, door handles, etc., but is not limited thereto, and it is feasible to use it on any other items that need to be locked.
[0053] First, combined with Figures 1 - 3As shown, in an embodiment of the present application, the stainless steel padlock 100 includes a lock body 110, a lock core 120, a lock core accessory 130, a lock hook 150, and a key 160. Among them, a hollow accommodation cavity 111 is provided inside the lock body 110, and the accommodation cavity 111 communicates with the outside through an entrance 112, and the entrance 112 is provided on a side wall of the lock body 110. The lock hook 150 is movably installed on the lock body 110 and extends into the accommodation cavity 111. The lock core 120 is rotatably installed in the accommodation cavity 111 and cooperates with the lock hook 150. The lock core 120 can hold the lock hook 150 in the locked position and can release the lock hook 150 to move the lock hook 150 to the unlocked position. The lock core accessory 130 is fixed in the accommodation cavity 111 and is docked with the lock core 120. A hollow channel 131 and an accessory groove 132 are provided on the lock core accessory 130. The hollow channel 131 extends along the axial direction of the lock core accessory 130 and penetrates both ends thereof. The accessory groove 132 extends along the radial direction of the lock core accessory 130 and communicates with the hollow channel 131. A convex block 1621 is convexly provided on the surface of the key 160, and the convex block 1621 can be slidably engaged with the accessory groove 132, so that the key 160 can slide in and out of the lock core 120 along the hollow channel 131 and the accessory groove 132 to drive the lock core 120 to rotate and transform from the locked position to the unlocked position.
[0054] Continuing to combine Figures 1 - 3 As shown, in an embodiment of the present application, the stainless steel padlock 100 further includes a sleeve assembly 140. The sleeve assembly 140 is installed on the lock body 110 and extends into the accommodation cavity 111. One end of the sleeve assembly 140 always abuts against the lock core 120 to stably hold the lock core 120 in the locked position or the unlocked position, as will be described later in detail.
[0055] Next, in combination with Figure 2 , Figure 9 As shown, in an embodiment of the present application, at least one accessory groove 132 is provided, and it is specifically set corresponding to the number of convex blocks 1621 provided on the key. And, in the axial direction of the lock core accessory 130, the accessory groove 132 can penetrate both ends in the axial direction of the lock core accessory 130, or can only penetrate one end in the axial direction of the lock core accessory 130. In a specific embodiment, one accessory groove 132 is provided on the lock core accessory 130. The length direction of the accessory groove 132 penetrates both ends in the axial direction of the lock core accessory 130. The width direction of the accessory groove 132 extends along the radial direction of the lock core accessory 130, and the outer diameter of the accessory groove 132 is larger than the outer diameter of the convex block 1621 to allow the convex block 1621 to slide along the accessory groove 132.
[0056] Combined with Figures 10 - 12As shown, after the lock cylinder sub-component 130 is fixed within the accommodation cavity 111, the lock cylinder sub-component 130 is just installed within the access port 112, and one end of the lock cylinder sub-component 130 is flush with one side surface of the lock body 110. In this way, when the key 160 needs to be inserted into the lock cylinder 120, the key body 162 (details will be described later) needs to be inserted into the hollow channel 131, and the protrusion 1621 thereon needs to be inserted into the sub-component groove 132, and the key 160 is pushed to slide along the hollow channel 131 and the sub-component groove 132 so that the key 160 can be successfully inserted into the lock cylinder 120. When the key 160 is incorrect or the protrusion 1621 on the key 160 does not correspond to the sub-component groove 132, the key 160 cannot be inserted into the lock cylinder 120, thus improving the usage safety.
[0057] Understandably, in other embodiments, the number and position of the sub-component grooves 132 are flexibly set according to the number and position of the protrusions 1621 provided on the key body 162.
[0058] Next, in conjunction with Figure 2 , Figures 4 - 7 , Figure 11 As shown, in one embodiment of the present application, a lock cylinder inner cavity 121 is provided on the lock cylinder 120. The lock cylinder inner cavity 121 extends along the axial direction of the lock cylinder 120, and the lock cylinder inner cavity 121 penetrates through one end of the lock cylinder 120 close to the lock cylinder sub-component 130, so that the lock cylinder inner cavity 121 communicates with the hollow channel 131, as Figure 11 shown. In this way, when the key 160 passes through the lock cylinder sub-component 130, it can be detachably inserted into the lock cylinder inner cavity 121, as Figure 11 shown, and the key 160 can be relatively positioned with the lock cylinder 120 to drive the lock cylinder 120 to rotate and unlock. The key 160 can drive the lock cylinder 120 to rotate only after passing through the lock cylinder sub-component 130. During this process, the lock cylinder sub-component 130 will not rotate along with it because it is fixed within the lock body 110. In this way, even if the lock cylinder sub-component 130 is touched during use, the lock cylinder 120 will not rotate, thus effectively avoiding unlocking against the user's will and improving the user experience.
[0059] In conjunction with Figures 4 - 7 , Figure 11 , Figure 15 As shown, in a preferred embodiment, a lock cylinder groove 122 is further provided on the lock cylinder 120. The lock cylinder groove 122 extends along the radial direction of the lock cylinder 120 and communicates with the lock cylinder inner cavity 121. The lock cylinder groove 122 corresponds to the aforementioned sub-component groove 132, and through the rotation of the lock cylinder 120, the lock cylinder groove 122 can be made to correspond and communicate with or be misaligned with the sub-component groove 132. The so-called corresponding communication here means that the two correspond to each other in the radial direction of the lock cylinder 120, so that the two are axially penetrated along the lock cylinder 120, as Figure 11As shown, the phase misalignment means that the two are staggered in the radial direction of the lock core 120 by rotating the lock core 120, as shown in FIG. Figure 15 shown.
[0060] See also Figure 11 As shown, when the lock core groove 122 and the auxiliary component groove 132 are correspondingly connected, the protrusion 1621 can slide along the two. Figure 15 As shown, when the lock core groove 122 and the auxiliary component groove 132 are misaligned, the protrusion 1621 abuts against the inner end surface of the lock core auxiliary component 130 . In this way, only when the lock core 120 is in the locked position and the lock core groove 122 and the auxiliary component groove 132 on them correspond to and are connected, can the protrusion 1621 slide along the two, and the key 160 can be inserted into the lock core 120 or slid out of the lock core 120; and when the lock core 120 is rotated to the unlocking position, the lock core groove 122 and the auxiliary component groove 132 are staggered. At this time, the protrusion 1621 just abuts against the inner end surface of the lock core auxiliary component 130, thereby achieving the purpose of jamming the key 160 and preventing the key 160 from accidentally falling out of the lock body 110. At this time, even if the key 160 is subjected to outward pulling force, the protrusion 1621 on it can abut against the lock core auxiliary component 130 to prevent the key 160 from being pulled out, so that the key 160 is always kept on the lock body 110, thereby improving the user experience.
[0061] It is understandable that in other embodiments, the lock core 120 may not be provided with a lock core groove 122, but the inner diameter of the lock core cavity 121 is made larger than the maximum outer diameter of the key 160 and its protrusion 1621, so that the key 160 and the protrusion 1621 can be inserted into the lock core cavity 121, and the key 160 with the protrusion 1621 can also be plugged into the lock core 120.
[0062] Combine the following Figures 1 - 2 , Figures 10 - 18 As shown, in one embodiment of the present application, the key 160 specifically includes a key handle 161 and a key body 162 connected to each other. The key body 162 is used to cooperate with the lock cylinder 120 and drive the lock cylinder 120 to rotate, and the key handle 161 is used for user operation. More preferably, the key body 162 is roughly cylindrical in structure. Of course, the key body 162 can also be set to other shapes. The surface of the key body 162 is convexly provided with the protrusion 1621, and the protrusion 1621 is preferably convexly provided at the end of the key body 162. The end face of the key body 162 is also provided with an end face recessed hole 1622, and the end face recessed hole 1622 extends along the axial direction of the key body 162, as shown in FIG. Figure 11 , Figure 15As shown, when the key body 162 is inserted into the lock core 120, the positioning post 123 (to be described later in detail) connected to the inside of the lock core 120 through the end face concave hole 1622 realizes the relative positioning of the key 160 and the lock core 120, enabling the key 160 to drive the lock core 120 to rotate. At this time, the key handle 161 is located outside the lock body 110 for the user to operate. By rotating the key handle 161, the key body 162 is driven to rotate, and then the lock core 120 is driven to rotate.
[0063] The following will be described in conjunction with Figures 4 - 5 , Figure 11 , Figure 15 As shown, in an embodiment of the present application, a positioning post 123 is provided on the inner end face of the lock core inner cavity 121. The positioning post 123 extends along the axial direction of the lock core 120 (as shown in Figures 4 - 5 ). The positioning post 123 is preferably integrally formed with the lock core 120. Correspondingly, the inner diameter of the end face concave hole 1622 is matched with the outer diameter of the positioning post 123. Combining Figure 11 , Figure 15 As shown, when the key body 162 is inserted into the lock core inner cavity 121, the positioning post 123 is inserted into the end face concave hole 1622, thereby fixing the key body 162, realizing the connection between the key 160 and the lock core 120 and making the two relatively positioned, making the connection between the two simpler and more convenient.
[0064] It can be understood that in other embodiments, the positioning post 123 and the lock core 120 can also be formed separately and then assembled. For example, in a specific embodiment, the outer diameter of one end of the positioning post 123 is reduced to form a connecting thin rod, and a connecting hole corresponding to the connecting thin rod is opened on the inner end face of the lock core inner cavity 121. The connecting thin rod is inserted into the connecting hole and tightly fitted, thereby realizing the installation of the positioning post 123 and making the installation of the positioning post 123 more convenient. Of course, it is also feasible to set / install the positioning post 123 by other means.
[0065] The following will be described in conjunction with Figures 6 - 7 As shown, in an embodiment of the present application, a hook portion 124 and a lock core stopper 125 are further provided at one end of the lock core 120 away from the lock core inner cavity 121. Among them, the hook portion 124 and the lock core stopper 125 are both provided on the end face of the lock core 120 and have a height difference. Specifically, the lock core stopper 125 is located above the hook portion 124. By rotating the lock core 120, the hook portion 124 and the lock core stopper 125 can be respectively abutted against the lock hook 150, thereby holding the lock hook 150 in the locked position and the unlocked position.
[0066] The following will be described in conjunction with Figures 6 - 7 , Figure 13 , Figure 17As shown, in a specific embodiment, the lock core stopper 125 extends substantially along the diameter direction of the end face of the upper edge lock core 120, and the lock core stopper 125 has a lower end face 1251 with a curved surface and an upper end face 1252 with a planar structure, as Figure 7 shown. The top end of the hook portion 124 is connected to one end of the lock core stopper 125. The hook portion 124 extends downward from the lock core stopper 125 and has an arc-shaped structure. An abutting end 1241 is formed at the bottom end of the hook portion 124 away from the lock core stopper 125, so that there is a height difference between the abutting end 1241 and the lower end face 1251 of the lock core stopper 125, as Figure 7 shown.
[0067] Combined with Figure 13 、 Figure 17 shown, when the abutting end 1241 of the hook portion 124 abuts against the lock hook 150, the lock hook 150 is held in the locked position, as Figure 13 shown. When the lock core 120 rotates and the abutting end 1241 of the hook portion 124 disengages from the lock hook 150, the lock hook 150 can move upward and abut against the lower end face 1251 of the lock core stopper 125, thereby holding the lock hook 150 in the unlocked position, as Figure 17 shown.
[0068] Next, combined with Figures 4 - 8 shown, in an embodiment of the present application, an abutting platform 126 is further provided on the side wall of the lock core 120. The abutting platform 126 is formed by recessing from the outer surface of the lock core 120, and the abutting platform 126 is disposed offset from the axis line P of the lock core 120. Specifically, the inner edge of the abutting platform 126 is at a certain distance from the axis line P of the lock core 120. In this way, when an external force is applied to the abutting platform 126, the lock core 120 can be rotated along its axis line P, so that the lock core 120 rotates towards its locked position.
[0069] Next, combined with Figures 2 - 3 、 Figure 12 、 Figure 16 shown, in an embodiment of the present application, the sleeve assembly 140 is installed on the lock body 110 and always abuts against the abutting platform 126. The sleeve assembly 140 always exerts a downward force on the lock core 120 (see Figure 12 、 Figure 16 shown), so as to stably hold the lock core 120 in the locked position or the unlocked position.
[0070] Combined with Figure 3 、 Figure 13 、 Figures 17 - 18As shown, in a specific embodiment, the sleeve assembly 140 includes at least a sleeve 141 and a first elastic member 142 disposed within the sleeve 141. The sleeve 141 is movably mounted on the lock body 110 with one end protruding into the accommodation cavity 111. Specifically, the sleeve 141 protrudes above the abutting platform 126. The elastic force of the first elastic member 142 causes the lower end of the sleeve 141 to always abut against the abutting platform 126. Thus, when the hook portion 124 or the lock core stopper 125 abuts against the lock hook 150, the lock hook 150 exerts an upward force on the lock core 120, and the sleeve assembly 140 exerts a downward force on the lock core 120, thereby keeping the lock core 120 from rotating and stably maintaining the lock core 120 in the locked position or the unlocking position, as Figure 13 , Figures 17 - 18 shown. Additionally, when the lock core 120 is subjected to an external force and rotates from the unlocking position shown in Figures 17 - 18 to the locked position shown in Figure 13 , the elastic force of the first elastic member 142 also provides a driving force for the lock core 120 to reset. That is, the elastic force of the first elastic member 142 when it recovers from deformation drives the lock core 120 to rotate towards its locked position, thereby enabling the lock core 120 to be quickly locked.
[0071] Continuing to refer to Figure 3 , Figure 12 shown, in this specific embodiment, the sleeve assembly 140 further includes a plug cap 143. A positioning protrusion 144 protrudes from the plug cap 143. The plug cap 143 and the positioning protrusion 144 can be integrally formed or fixedly connected after being separately formed. The end of the first elastic member 142 remote from the sleeve 141 is sleeved on the positioning protrusion 144 and abuts against the plug cap 143. Specifically, the upper end of the first elastic member 142 is sleeved on the positioning protrusion 144 and abuts against the plug cap 143. By connecting the plug cap 143 to the main body cover plate 116 (see details later) and positioning the upper end of the first elastic member 142 through the positioning protrusion 144, not only is the installation of the first elastic member 142 more convenient, but also during the process of the lock core 120 rotating and pushing the sleeve 141 to move, when the sleeve 141 squeezes the first elastic member 142 to deform, the first elastic member 142 is not easily deflected.
[0072] In this embodiment, the first elastic member 142 is preferably a spring, but is not limited thereto. Of course, other elastic components can also be selected.
[0073] Next, referring to Figures 1 - 2 , Figures 10 - 18As shown, in an embodiment of the present application, the locking hook 150 includes a locking hook long rod 151 and a locking hook short rod 152. The locking hook long rod 151 and the locking hook short rod 152 are preferably integrally formed. A locking hook end portion 1521 is provided on the end face of the locking hook short rod 152. The locking hook long rod 151 is movably installed on the lock body 110 and extends into the accommodation cavity 111. The bottom end of the locking hook long rod 151 is detachably clamped with the lock core 120, so that the locking hook end portion 1521 of the locking hook short rod 152 is inserted into the lock body 110 to realize the locking function or disengaged from the lock body 110 to realize the unlocking function.
[0074] As shown in the following in conjunction with Figure 2 、 Figure 11 、 Figure 15 In this embodiment, a bottom end groove 1511 is provided at the bottom of the locking hook long rod 151. A second elastic member 153 is provided in the bottom end groove 1511, and the other end of the second elastic member 153 abuts against the lock body 110. The elastic force provided by the second elastic member 153 causes the locking hook long rod 151 to always have a tendency to move towards the unlocking position. Specifically, the locking hook long rod 151 always has an upward movement tendency.
[0075] In this embodiment, the second elastic member 153 is preferably a spring, but is not limited thereto. Of course, other elastic components can also be selected.
[0076] As shown in the following in conjunction with Figure 11 、 Figure 13 、 Figure 15 、 Figures 17 - 18 In this embodiment, a clamping platform 1512 is provided at the end of the locking hook long rod 151. The clamping platform 1512 is arranged radially along the locking hook long rod 151 and has an annular structure. By the abutment of the clamping platform 1512 with the hook portion 124 and the lock core stopper 125 respectively, the switching of the locking hook 150 between the locking position and the unlocking position is realized. Specifically, when the abutting end 1241 of the clamping platform 1512 abuts against the hook portion 124, the locking hook 150 is locked by the lock core 120 and is in the locked position, as shown in Figure 13 As shown, at this time, the locking hook long rod 151 squeezes the second elastic member 153 to cause it to deform. When the lock core 120 rotates to make the abutting end 1241 of the hook portion 124 disengage from the clamping platform 1512, the second elastic member 153 recovers its deformation and drives the locking hook long rod 151 to move upward until the clamping platform 1512 abuts against the lower end face 1251 of the lock core stopper 125, as shown in Figures 17 - 18 As shown, at this time, the lock hook 150 moves to the unlocking position, and the clamping platform 1512 abuts against the lock core stopper 125, preventing the elastic force of the second elastic member 153 from ejecting the long rod 151 of the lock hook out of the lock body 110. That is, the lock core stopper 125 holds the lock hook 150 in the unlocking position and prevents it from detaching from the lock body 110.
[0077] Continuing to combine Figure 11 、 Figure 13 、 Figure 15 、 Figures 17 - 18 As shown, in this embodiment, a pushing surface 1513 is further provided at the end of the long rod 151 of the lock hook. The pushing surface 1513 is arranged along the radial direction of the long rod 151 of the lock hook and has an annular structure, and the pushing surface 1513 is arranged above the clamping platform 1512. Refer to Figures 17 - 18 As shown, when the clamping platform 1512 abuts against the lower end surface 1251 of the lock core stopper 125, the pushing surface 1513 just abuts against the upper end surface 1252 of the lock core stopper 125. In this way, when the lock hook 150 is extruded and moved downward by an external force, the lock core stopper 125 is pushed by the pushing surface 1513, thereby driving the lock core 120 to rotate towards its locking position, and the lower end of the long rod 151 of the lock hook presses the second elastic member 153 again to deform it until the lock core 120 rotates to the locking position and locks the lock hook 150 again.
[0078] In this application, the lock hook 150 is preferably in a U-shaped structure, but it is not limited thereto, and it is also feasible to set it in other shapes.
[0079] Next, combining again with Figures 2 - 3 As shown, in an embodiment of this application, the upper surface of the lock body 110 is further provided with a spaced lock hole 113 and a mounting hole 114. The lock hole 113 communicates with the accommodating cavity 111. The long rod 151 of the lock hook 150 is movably installed in the mounting hole 114. By moving the long rod 151 of the lock hook, the hook end 1521 of the short rod 152 of the lock hook is inserted into or detached from the lock hole 113, realizing the locking function or unlocking function of the lock hook 150.
[0080] Combining with Figures 1 - 3 As shown, in a preferred embodiment, a main body groove 115 is further recessed on the upper surface of the lock body 110. The main body groove 115 is arranged between the mounting hole 114 and the lock hole 113. And a sleeve through hole 1151 communicating with the accommodating cavity 111 is further opened in the main body groove 115. The above-mentioned sleeve assembly 140 is installed in the sleeve through hole 1151. Specifically, the first elastic member 142 and the sleeve 141 are both accommodated in the sleeve through hole 1151, and the lower end of the sleeve 141 protrudes onto the abutting platform 126. This structural setting makes the installation of the sleeve assembly 140 more convenient.
[0081] Continue to combine Figures 1 - 3 As shown, in a preferred embodiment, the stainless steel padlock 100 further includes a main body cover plate 116, and the shape of the main body cover plate 116 corresponds to the shape of the main body groove 115. The main body cover plate 116 is detachably mounted in the main body groove 115. And when the main body cover plate 116 is installed, the upper surface of the main body cover plate 116 is on the same horizontal plane as the upper surface of the lock body 110.
[0082] Refer to Figure 3 As shown, more preferably, there are cooperating positioning posts 1161 and positioning holes 1152 between the main body cover plate 116 and the main body groove 115, and the detachable connection of the main body cover plate 116 is realized through the positioning posts 1161 and the positioning holes 1152. In a specific embodiment, two positioning holes 1152 are formed in the main body groove 115, and the two positioning holes 1152 are arranged along the diagonal line of the main body groove 115. Correspondingly, two positioning posts 1161 protrude from the diagonal line of the main body cover plate 116, and the installation of the main body cover plate 116 is realized by inserting the two positioning posts 1161 into the two positioning holes 1152, so that the connection of the main body cover plate 116 in the main body groove 115 is more stable.
[0083] In this application, the stainless steel padlock 100 is made of stainless steel material, so that its surface is smooth and has luster, more textured, more beautiful in design, and has better wear resistance, anti-aging property and impact resistance.
[0084] Next, combine again Figures 1 - 18 As shown, the working principle and process of the stainless steel padlock 100 of the present invention will be described.
[0085] First, combine Figure 1 、 Figures 10 - 12 As shown, when unlocking is required, the correct key 160 is inserted into the lock core 120. Specifically, the key body 162 is inserted into the hollow channel 131 of the lock core accessory 130, and at the same time, the convex block 1621 is inserted into the accessory groove 132 thereof, and the key 160 is pushed inward, so that the key body 162 slides along the hollow channel 131 and the convex block 1621 slides along the accessory groove 132, thereby smoothly inserting the key 160 into the lock core 120.
[0086] Refer to Figures 11 - 12As shown, after the key body 162 is inserted into the key core cavity 121 of the key core 120, the end face concave hole 1622 on the key body 162 just passes through the positioning post 123, thereby tightly connecting the key body 162 and the key core 120 to achieve positioning between the two, enabling the key 160 to drive the key core 120 to rotate. At this time, the convex block 1621 disengages from the accessory groove 132 of the key core accessory 130 and enters the key core groove 122, and the convex block 1621 and the key core groove 122 are positioned relative to each other in the radial direction of the key core 120. That is to say, the key 160 cannot rotate alone to disengage the convex block 1621 from the key core groove 122, thereby further strengthening the positioning between the key body 162 and the key core 120 when the key 160 drives the key core 120 to rotate.
[0087] Combined with Figures 14 - 18 As shown, when the key handle 161 is rotated to drive the key body 162 to rotate, the key body 162 drives the key core 120 to rotate. During the unlocking process of the key core 120 rotation, the abutting platform 126 at its upper end pushes the sleeve assembly 140 upward, thereby squeezing the first elastic member 142 to deform it, as Figure 16 shown. When the key core 120 rotates to make the abutting end 1241 of the hook portion 124 disengage from the engaging platform 1512 of the lock hook 150, that is, when the key core 120 rotates to the unlocking position, at this time the second elastic member 153 resumes deformation and drives the lock hook long rod 151 upward until the engaging platform 1512 abuts against the lower end face 1251 of the key core stopper 125, as Figure 17 shown. At this time, the lock hook 150 moves to the unlocking position, and the engaging platform 1512 abuts against the key core stopper 125, thereby preventing the elastic force of the second elastic member 153 from ejecting the lock hook long rod 151 out of the lock body 110, and the lock hook end 1521 of the lock hook short rod 152 disengages from the lock hole 113 and is in the unlocking state, as Figures 14 - 16 shown. In this unlocking state, the elastic force generated by the first elastic member 142 of the sleeve assembly 140 acts downward on the key core 120, and the elastic force generated by the second elastic member 153 acts upward on the key core 120, as Figures 17 - 18 shown, so as to keep the position of the key core 120 stable and stably hold the key core 120 in the unlocking position.
[0088] Next, refer to Figures 14 - 15 shown. When the key core 120 is in the unlocking position, the key core groove 122 on it rotates to be staggered from the accessory groove 132, so that the convex block 1621 just abuts against the inner end face of the key core accessory 130, which can prevent the key 160 from accidentally falling off the lock body 110. At this time, even if the key 160 is subjected to an outward pulling force, the convex block 1621 on it can abut against the key core accessory 130 to prevent the key 160 from being pulled out, so that the key 160 is always held on the lock body 110, improving the user experience.
[0089] Combined again Figures 10 - 14 , Figure 18 As shown, when locking again is required, the locking hook 150 is pushed downward to move it downward. During this process, the lower end of the long rod 151 of the locking hook presses against the second elastic member 153 again to deform it. At the same time, the pushing surface 1513 on the long rod 151 of the locking hook pushes against the upper end surface 1252 of the lock core stopper 125 to drive the lock core 120 to rotate towards the locking position. During the rotation of the lock core 120, the elastic force generated by the restoration of the deformation of the first elastic member 142 of the sleeve assembly 140 pushes against the abutting platform 126. Since the abutting platform 126 is offset from the axis line P of the lock core 120, it also pushes the lock core 120 to rotate towards its locking position, that is, the lock core 120 is driven by the first elastic member 142 to rotate and reset, so that the lock core 120 can be quickly and labor-savingly rotated to the locking position.
[0090] As Figures 10 - 13 shown, when the lock core 120 and the key 160 rotate to the locking position again, the second elastic member 153 is compressed again (see Figure 11 ), at the same time, the abutting end 1241 of the hook portion 124 on the lock core 120 abuts against the clamping table 1512 again (see Figure 13 ), and the locking hook 150 is abutted by the lock core 120 and is in the locked position. At this time, the elastic force generated by the first elastic member 142 of the sleeve assembly 140 acts downward on the lock core 120, and the elastic force generated by the second elastic member 153 acts upward on the lock core 120. As Figure 13 shown, the lock core 120 is thus held in the locking position to maintain the stability of the locked state. And the locking hook end portion 1521 of the short rod 152 of the locking hook is inserted into the lock hole 113 again and is in the locked state, as Figures 10 - 12 shown.
[0091] Combined again Figure 1 , Figures 10 - 11 shown, when the stainless steel padlock 100 is locked again, the key 160 rotates to the state as Figure 10 shown. At this time, the lock core groove 122 on the lock core 120 rotates to the position corresponding to the accessory groove 132 again, and the two are connected axially along the lock core 120, as Figure 11 shown, so that the convex block 1621 just corresponds to the accessory groove 132. Pull the key 160 outward along the accessory groove 132, so that the key body 162 slides along the hollow channel 131 and the convex block 1621 slides along the accessory groove 132, and the key 160 can be pulled out.
[0092] Combined with the above description, the stainless steel padlock 100 of the present invention has the following technical effects:
[0093] 1. Add a lock core sub-component 130, fix the lock core sub-component 130 inside the lock body 110 and dock it with the lock core 120. The key 160 can drive the lock core 120 to rotate only after passing through the lock core sub-component 130. Moreover, during the process of the key 160 driving the lock core 120 to rotate, the lock core sub-component 130 remains stationary. Therefore, even when the key 160 is pulled out, if someone touches the lock core sub-component 130, it will not cause the lock core 120 to rotate. Compared with the prior art, it can effectively avoid the situation where the lock core 120 rotates due to accidental human touch, thereby effectively avoiding unlocking against the subjective will, improving the locking security and enhancing the user experience;
[0094] 2. The lock core sub-component 130 is provided with a hollow channel 131 and a sub-component groove 132. The hollow channel 131 extends along the axial direction of the lock core sub-component 130 and penetrates both ends thereof. The sub-component groove 132 extends along the radial direction of the lock core sub-component 130 and communicates with the hollow channel 131. Secondly, a convex block 1621 is provided on the surface of the key 160. The convex block 1621 can be slidably matched with the sub-component groove 132, so that the key 160 can slide in and out of the lock core 120 along the hollow channel 131 and the sub-component groove 132. In this way, when the key 160 drives the lock core 120 to rotate to the unlocking position, the convex block 1621 just engages with the inner end face of the lock core sub-component 130 to achieve the purpose of clamping the key 160, preventing the key 160 from accidentally falling out of the lock body 110. At this time, even if the key 160 is subjected to an outward pulling force, the convex block 1621 thereon can abut against the lock core sub-component 130 to prevent the key 160 from being pulled out, so that the key 160 is always held on the lock body 110, enhancing the user experience;
[0095] 3. The traditional encrypted side structure is cancelled on the outer surface of the key 160, and only the convex block 1621 is provided on the surface of the key 160, which simplifies the structures of both the key 160 and the interior of the lock body 110, reduces the number of components, further simplifies the production process, reduces the production cost, and is more conducive to commercial promotion and application.
[0096] Other structures of the stainless steel padlock 100 involved in the present invention are all conventional structures well known to those of ordinary skill in the art and will not be described in detail here.
[0097] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
