Description
Technical Field
[0001] This utility model relates to the field of padlock technology, and in particular to a stainless steel padlock that can prevent accidental unlocking due to human touch of the lock cylinder and has a simple structure. Background Technology
[0002] Padlocks are commonly used in luggage, lockers, suitcases, door handles, and other applications. A typical traditional padlock generally consists of a lock body, a U-shaped hook, a lock cylinder, and a key. The lock body is generally rectangular in shape and houses the lock cylinder. The U-shaped hook is attached to one end of the lock body, and the other end has a keyhole. When the correct key is inserted into the keyhole, the lock cylinder can be rotated to disengage the locking mechanism from the U-shaped hook, allowing it to slide out of the lock body. When the short leg of the U-shaped hook is completely removed from the lock body or separated from it in the unlocked state, the padlock can be removed from or attached to the latches or other similar parts of the luggage to be locked.
[0003] However, existing padlock cylinders typically have one end exposed outside the lock body, allowing the key to be directly inserted into the cylinder. This design makes it easy to accidentally rotate the cylinder, causing unintentional unlocking and impacting security and user experience. To prevent accidental cylinder rotation and enhance the padlock's security, an encryption side (complex serrations) is usually added to the key surface, along with various encryption pins or push pins and auxiliary springs within the lock body. However, this encryption side design leads to extremely complex manufacturing processes, requiring numerous components and resulting in high costs, hindering commercial adoption.
[0004] Therefore, it is necessary to provide a stainless steel padlock that can prevent accidental unlocking by human touch of the lock cylinder, thus solving the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this utility model is to provide a stainless steel padlock that can prevent accidental unlocking due to human error.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a stainless steel padlock is provided, comprising a lock body, a lock cylinder rotatably installed within the lock body, and a lock hook movably installed within the lock body. The stainless steel padlock further comprises a lock cylinder sub-component, which is fixed within the lock body and connected to the lock cylinder. A hollow channel is provided on the lock cylinder sub-component, which extends along the axial direction of the lock cylinder sub-component and passes through both ends therethrough. The hollow channel is used for a key to slide and connect or disconnect from the lock cylinder.
[0007] Preferably, the stainless steel padlock also includes a key with a raised protrusion on its surface; the lock cylinder sub-component also has a sub-component groove, which extends radially along the lock cylinder sub-component and connects to the hollow channel. The sub-component groove is used for the sliding of the raised protrusion, thereby allowing the key to slide along the hollow channel and the sub-component groove to enter and exit the lock cylinder. Therefore, the key can only be inserted into the lock cylinder and rotate to unlock it when the raised protrusion can engage with and slide within the sub-component groove. If the key is incorrect, the raised protrusion will be blocked, preventing the key from being inserted into the lock cylinder, thus improving security. In the unlocked state, the protrusion abuts against the inner end face of the lock cylinder sub-component, preventing the key from moving axially along the lock cylinder and thus locking the key. This prevents the key from accidentally falling out of the lock body. Even if the key is subjected to outward pulling force, the protrusion against the lock cylinder sub-component prevents the key from being pulled out, keeping the key firmly in place and improving the user experience. Only after the lock cylinder is rotated back to lock can the protrusion move to the position corresponding to the groove in the sub-component, allowing it to slide along the groove and remove the key. Furthermore, the traditional encryption side structure on the outer surface of the key is eliminated, with the protrusion only on the surface of the key. This simplifies the internal structure of both the key and the lock body, reduces the number of components, simplifies the manufacturing process, lowers production costs, and facilitates commercial application.
[0008] Preferably, the lock cylinder has a lock cylinder groove that extends radially along the lock cylinder and passes through one end near the lock cylinder sub-component. When the lock cylinder rotates, the lock cylinder groove can be aligned with or misaligned with the groove of the sub-component. When the lock cylinder groove and the sub-component groove are aligned and connected, the protrusion can slide along both, allowing the key to be inserted into or removed from the lock cylinder. Furthermore, the engagement of the lock cylinder groove and the protrusion achieves relative radial positioning between the key and the lock cylinder, making the key's rotation of the lock cylinder more stable. When the lock cylinder groove and the sub-component groove are misaligned, the protrusion abuts against the inner end face of the lock cylinder sub-component, thereby locking the key and preventing it from accidentally falling off the lock body. Even if the key is subjected to outward pulling force, the protrusion can still abut against the lock cylinder sub-component to prevent the key from being pulled out, thus keeping the key on the lock body at all times and improving the user experience.
[0009] Preferably, the lock cylinder has an inner cavity that extends axially along the lock cylinder and passes through one end near the lock cylinder sub-component to connect with the hollow channel. A positioning post protrudes from the inner end face of the inner cavity. The end face of the key has a concave hole corresponding to the positioning post. When the key is inserted into the inner cavity of the lock cylinder, the positioning post is inserted into the concave hole, thereby achieving a tight connection between the key and the lock cylinder, allowing the key to drive the lock cylinder to rotate.
[0010] Preferably, the positioning post is integrally formed with the lock cylinder.
[0011] Preferably, a connecting hole is provided on the inner end face of the lock cylinder cavity, and one end of the positioning pin is inserted into the connecting hole and fastened to the lock cylinder, making the installation of the positioning pin more convenient.
[0012] Preferably, the key includes a connected key body and a key handle, the protrusion is protruding from the surface of the key body, the end face recess is opened at the end of the key body and extends along its axial direction, the key body is detachably inserted into the lock cylinder and can drive the lock cylinder to rotate, and the key handle is located outside the lock body for user operation.
[0013] Preferably, the end of the lock cylinder away from the lock cylinder sub-component is further provided with a lock cylinder stop and a hook portion. The lock cylinder stop and the hook portion are spaced apart and have a height difference. By rotating the lock cylinder, the hook portion and the lock cylinder stop can respectively abut against the lock hook, thereby keeping the lock hook in the locked position or the unlocked position.
[0014] Preferably, the latch portion extends downward from one end of the lock cylinder stop, and when the end of the latch portion away from the lock cylinder stop abuts against the lock hook, the lock hook is held in the locked position. When the lock cylinder rotates and the latch portion disengages from the locking end face, the lock hook can move upward and abut against the lower end of the lock cylinder stop, holding the lock hook in the unlocked position.
[0015] Preferably, the lock cylinder stop has an upper end face and a lower end face that are disposed opposite to each other. When the lock hook is in the unlocked position, the lock hook abuts against the lower end face of the lock cylinder stop. When the lock hook is driven downward by an external force, it can push the upper end face of the lock cylinder stop and drive the lock cylinder to rotate toward the locked position.
[0016] Preferably, the lock cylinder is further provided with an abutting platform on its side wall. The abutting platform is offset from the axis of the lock cylinder. When the abutting platform is subjected to force, the lock cylinder can rotate along its axis toward the locking position.
[0017] Preferably, the stainless steel padlock further includes a sleeve assembly, which is movably disposed within the lock body and always abuts against the abutment platform, thereby stably holding the lock cylinder in the locked or unlocked position by the force provided by the sleeve assembly.
[0018] Preferably, the sleeve assembly includes at least a sleeve and a first elastic element installed inside the sleeve. The sleeve is movably installed in the lock body and corresponds to the abutment platform. The elastic force of the first elastic element ensures that the sleeve always abuts against the abutment platform, so as to stably hold the lock cylinder in the locked position or the unlocked position.
[0019] Preferably, the sleeve assembly further includes a plug and a positioning protrusion protruding from the plug. The end of the first elastic member away from the sleeve is sleeved on the positioning protrusion and abuts against the plug. The first elastic member is positioned by the plug and the positioning protrusion, so that the first elastic member is not easily deflected when the lock cylinder is rotated and deformed by compression.
[0020] Preferably, the lock hook includes a long lock hook rod and a short lock hook rod. The long lock hook rod is movably installed on the lock body, and the end of the long lock hook rod is provided with a locking platform. The lock hook can be held in the locked position or the unlocked position by the abutment of the locking platform with the lock cylinder, so that the short lock hook rod can be inserted into or disengaged from the lock hole on the lock body.
[0021] Preferably, the locking platform abuts against the locking hook portion and the locking cylinder stop portion of the lock cylinder respectively, thereby keeping the lock hook in the locked position and the unlocked position.
[0022] Preferably, the bottom of the lock hook rod is further provided with a bottom end groove, and a second elastic element is provided in the bottom end groove. The elastic force provided by the second elastic element makes the lock hook rod always tend to move towards the unlocking position. Through the contact between the locking platform and the locking hook part of the lock cylinder and the lock cylinder stop, the elastic force of the second elastic element prevents the lock hook rod from being ejected from the lock body.
[0023] Preferably, the end of the long rod of the lock hook is also provided with a pushing surface, which is located above the locking platform. When the locking platform abuts against the lower end of the lock cylinder stop, the pushing surface abuts against the upper end of the lock cylinder stop. When the lock hook is moved downward by an external force, the locking cylinder is driven to rotate to the locking position by pushing the lock cylinder stop through the pushing surface.
[0024] Preferably, the lock body is provided with spaced mounting holes and lock holes, and the lock hook long rod is movably mounted in the mounting hole. The lock hook short rod is inserted into or disengaged from the lock hole by moving the lock hook long rod.
[0025] Preferably, the end face of the lock hook for mounting the lock body is further recessed with a main body groove, and a sleeve through hole communicating with the interior of the lock body is opened 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 cover plate, the shape of which corresponds to the shape of the main groove, and the main cover plate is detachably installed in the main groove.
[0027] Preferably, the main cover plate and the main groove are detachably connected by matching positioning pins and positioning holes.
[0028] Preferably, when the main cover plate is placed inside the main groove, it is flush with the end face of the lock body.
[0029] Compared to existing technologies, this utility model's stainless steel padlock incorporates a lock cylinder sub-component. This sub-component is fixed within the lock body and connects to the lock cylinder. A hollow channel extends axially along the sub-component and passes through both ends, allowing the key to slide and connect or disconnect from the lock cylinder. Thus, the key can only rotate the lock cylinder by passing through the sub-component, and the sub-component remains stationary during rotation. Therefore, it is difficult to directly touch the lock cylinder during use, and even if someone accidentally touches the sub-component, the lock cylinder will not rotate. Compared to existing technologies, this effectively prevents accidental lock cylinder rotation, thus preventing unintentional unlocking and improving security and user experience.

It should be noted that the directional descriptions involved in the present invention, such as up, down, left, right, front, and back, indicating directions or positional relationships, are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing the technical solutions of this application or / and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first," "second," etc., described are only used to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.
[0049] Combination Figures 1-18As shown, the stainless steel padlock 100 provided by this utility model is particularly suitable for bags, lockers, suitcases, door handles, etc., but is not limited thereto, and can be used on any other items that need to be locked.
[0050] First combine Figures 1-3 As shown, in one embodiment of this application, the stainless steel padlock 100 includes a lock body 110, a lock cylinder 120, a lock cylinder assembly 130, a lock hook 150, and a key 160. The lock body 110 has a hollow receiving cavity 111 inside, which communicates with the outside through an inlet 112 located on one side wall of the lock body 110. The lock hook 150 is movably mounted on the lock body 110 and extends into the receiving cavity 111. The lock cylinder 120 is rotatably mounted in the receiving cavity 111 and cooperates with the lock hook 150. The lock cylinder 120 can hold the lock hook 150 in the locked position and can release the lock hook 150, allowing it to move to the unlocked position. The lock cylinder sub-component 130 is fixed within the receiving cavity 111 and docks with the lock cylinder 120. The lock cylinder sub-component 130 has a hollow channel 131 and a sub-component groove 132. The hollow channel 131 extends axially along the lock cylinder sub-component 130 and passes through both ends. The sub-component groove 132 extends radially along the lock cylinder sub-component 130 and connects to the hollow channel 131. The key 160 has a protruding protrusion 1621 on its surface. The protrusion 1621 can slide and engage with the sub-component groove 132, allowing the key 160 to slide along the hollow channel 131 and the sub-component groove 132 to enter and exit the lock cylinder 120, thereby causing the lock cylinder 120 to rotate and transition from the locked position to the unlocked position.
[0051] Continue to combine Figures 1-3 As shown, in one embodiment of this application, the stainless steel padlock 100 further includes a sleeve assembly 140, which is installed on the lock body 110 and extends into the receiving cavity 111. One end of the sleeve assembly 140 always abuts against the lock cylinder 120 to stably hold the lock cylinder 120 in the locked or unlocked position, as detailed below.
[0052] The following is combined Figure 2 , Figure 9As shown, in one embodiment of this application, the auxiliary part groove 132 is provided at least one, specifically corresponding to the number of protrusions 1621 provided on the key. Furthermore, in the axial direction of the lock cylinder auxiliary part 130, the auxiliary part groove 132 may extend through both ends of the lock cylinder auxiliary part 130 in the axial direction, or it may only extend through one end of the lock cylinder auxiliary part 130 in the axial direction. In a specific embodiment, the lock cylinder auxiliary part 130 is provided with an auxiliary part groove 132, the length direction of which extends through both ends of the lock cylinder auxiliary part 130 in the axial direction, the width direction of which extends radially along the lock cylinder auxiliary part 130, and the outer diameter of the auxiliary part groove 132 is larger than the outer diameter of the protrusion 1621, so as to allow the protrusion 1621 to slide along the auxiliary part groove 132.
[0053] Combination Figure 10-12 As shown, after the lock cylinder sub-component 130 is fixed in the receiving cavity 111, the lock cylinder sub-component 130 is precisely installed in the inlet 112, and one end of the lock cylinder sub-component 130 is flush with one side of the lock body 110. Thus, when the key 160 needs to be inserted into the lock cylinder 120, the key body 162 (described later) must be inserted into the hollow channel 131, and its protrusion 1621 must be inserted into the sub-component groove 132. The key 160 is then pushed to slide along the hollow channel 131 and the sub-component groove 132 to allow it to be smoothly inserted into the lock cylinder 120. If the key 160 is incorrect, or if 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 security.
[0054] Understandably, in other embodiments, the number and position of the sub-part recesses 132 are flexibly set according to the number and position of the protrusions 1621 provided on the key body 162.
[0055] The following is combined Figure 2 , Figure 4-7 , Figure 11 As shown, in one embodiment of this application, the lock cylinder 120 has a lock cylinder cavity 121, which extends axially along the lock cylinder 120 and penetrates the end of the lock cylinder 120 near the lock cylinder sub-part 130, thereby connecting the lock cylinder cavity 121 to the hollow channel 131. Figure 11 As shown. Thus, after the key 160 passes through the lock cylinder assembly 130, it can be detachably inserted into the inner cavity 121 of the lock cylinder, as... Figure 11As shown, the key 160 is positioned relative to the lock cylinder 120, causing the lock cylinder 120 to rotate and unlock. The key 160 can only drive the lock cylinder 120 to rotate after passing through the lock cylinder sub-component 130. During this process, the lock cylinder sub-component 130 will not rotate because it is fixed inside the lock body 110. Thus, even if the lock cylinder sub-component 130 is touched during use, it will not cause the lock cylinder 120 to rotate, thereby effectively preventing unintentional unlocking and improving the user experience.
[0056] Combination Figure 4-7 , Figure 11 , Figure 15 As shown, in a preferred embodiment, the lock cylinder 120 is further provided with a lock cylinder groove 122. The lock cylinder groove 122 extends radially along the lock cylinder 120 and communicates with the inner cavity 121 of the lock cylinder. The lock cylinder groove 122 corresponds to the aforementioned auxiliary part groove 132. Furthermore, by rotating the lock cylinder 120, the lock cylinder groove 122 and the auxiliary part groove 132 can be correspondingly connected or misaligned. The corresponding connection here means that the two correspond to each other radially in the lock cylinder 120, so that the two are connected axially along the lock cylinder 120. Figure 11 As shown, phase misalignment refers to the radial misalignment of the two components by rotating the lock cylinder 120, as shown in the figure. Figure 15 As shown.
[0057] See Figure 11 As shown, when the lock cylinder groove 122 and the auxiliary part groove 132 are correspondingly connected, the protrusion 1621 can slide along both. (See also...) Figure 15 As shown, when the lock cylinder groove 122 and the sub-part groove 132 are misaligned, the protrusion 1621 abuts against the inner end face of the lock cylinder sub-part 130. In this way, only when the lock cylinder 120 is in the locked position, so that the lock cylinder groove 122 on it corresponds to and connects with the auxiliary part groove 132, can the protrusion 1621 slide along the two, so that the key 160 can be inserted into the lock cylinder 120 or slide out of the lock cylinder 120. When the lock cylinder 120 is rotated to the unlock position, the lock cylinder groove 122 and the auxiliary part groove 132 are misaligned. At this time, the protrusion 1621 just abuts against the inner end face of the lock cylinder auxiliary part 130, so as to lock the key 160 and prevent 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 protrusion 1621 on it can abut against the lock cylinder auxiliary part 130 and prevent the key 160 from being pulled out, so that the key 160 is always kept on the lock body 110, improving the user experience.
[0058] Understandably, in other embodiments, the lock cylinder 120 may not have a lock cylinder groove 122. Instead, the inner diameter of the lock cylinder cavity 121 may be 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 cylinder cavity 121. This also allows the key 160 with the protrusion 1621 to be inserted into the lock cylinder 120.
[0059] The following is combined Figure 1-2 , Figure 10-18 As shown, in one embodiment of this application, the key 160 specifically includes a connected key handle 161 and a key body 162. The key body 162 is used to cooperate with the lock cylinder 120 and drive the lock cylinder 120 to rotate, while the key handle 161 is used for user operation. More preferably, the key body 162 is generally cylindrical in shape; of course, the key body 162 can also be other shapes. The surface of the key body 162 is provided with the protrusion 1621, which preferably protrudes from the end of the key body 162. The end face of the key body 162 is also provided with an end face recess 1622, which extends along the axial direction of the key body 162, such as... Figure 11 , Figure 15 As shown. When the key body 162 is inserted into the lock cylinder 120, the positioning pin 123 (described later) connected to the lock cylinder 120 through the end face recess 1622 achieves relative positioning of the key 160 and the lock cylinder 120, allowing the key 160 to drive the lock cylinder 120 to rotate. At this time, the key handle 161 is located outside the lock body 110 for user operation. Rotating the key handle 161 drives the key body 162 to rotate, which in turn drives the lock cylinder 120 to rotate.
[0060] The following is combined Figure 4-5 , Figure 11 , Figure 15 As shown, in one embodiment of this application, a positioning post 123 is provided on the inner end face of the lock cylinder cavity 121, and the positioning post 123 extends along the axial direction of the lock cylinder 120 (see...). Figure 4-5 As shown, the positioning pin 123 is preferably integrally formed with the lock cylinder 120. Correspondingly, the inner diameter of the end face recess 1622 matches the outer diameter of the positioning pin 123. Figure 11 , Figure 15 As shown, when the key body 162 is inserted into the inner cavity 121 of the lock cylinder, the positioning pin 123 is inserted into the end face recess 1622, thereby fixing the key body 162, realizing the connection between the key 160 and the lock cylinder 120 and positioning them relative to each other, making the connection between the two simpler and more convenient.
[0061] Understandably, in other embodiments, the positioning pin 123 and the lock cylinder 120 can also be formed separately and then assembled. For example, in one specific embodiment, the outer diameter of one end of the positioning pin 123 is reduced to form a connecting rod, and the inner end face of the lock cylinder cavity 121 has a connecting hole corresponding to the connecting rod. The connecting rod is inserted into the connecting hole and tightened to achieve the installation of the positioning pin 123, making the installation of the positioning pin 123 more convenient. Of course, it is also feasible to set / install the positioning pin 123 in other ways.
[0062] The following is combined Figures 6-7 As shown, in one embodiment of this application, the end of the lock cylinder 120 away from the inner cavity 121 is further provided with a hook portion 124 and a lock cylinder stop 125. The hook portion 124 and the lock cylinder stop 125 are both located on the end face of the lock cylinder 120 and have a height difference. Specifically, the lock cylinder stop 125 is located above the hook portion 124. Rotation of the lock cylinder 120 allows the hook portion 124 and the lock cylinder stop 125 to abut against the lock hook 150, thereby holding the lock hook 150 in the locked and unlocked positions.
[0063] The following is combined Figure 6-7 , Figure 13 , Figure 17 As shown, in one specific embodiment, the lock cylinder stop 125 extends approximately along the diametrical direction of the end face of the lock cylinder 120, and the lock cylinder stop 125 has a curved lower end face 1251 and a planar upper end face 1252, as shown. Figure 7 As shown. The top end of the hook portion 124 is connected to one end of the lock cylinder stop 125. The hook portion 124 extends downward toward the lock cylinder stop 125 and has an arc-shaped structure. The bottom end of the hook portion 124 away from the lock cylinder stop 125 forms an abutment end 1241, thereby creating a height difference between the abutment end 1241 and the lower end face 1251 of the lock cylinder stop 125. Figure 7 As shown.
[0064] Combination Figure 13 , Figure 17 As shown, when the abutting end 1241 of the latch 124 abuts against the locking hook 150, the locking hook 150 is held in the locked position, as... Figure 13 As shown. When the lock cylinder 120 rotates and the abutting end 1241 of the latch 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 cylinder stop 125, thereby holding the lock hook 150 in the unlocked position, as shown. Figure 17 As shown.
[0065] The following is combined Figures 4-8As shown, in one embodiment of this application, a contact platform 126 is further provided on the side wall of the lock cylinder 120. The contact platform 126 is formed by a recess in the outer surface of the lock cylinder 120, and the contact platform 126 is offset from the axis P of the lock cylinder 120. Specifically, the inner edge of the contact platform 126 is a certain distance away from the axis P of the lock cylinder 120. In this way, when the contact platform 126 is subjected to an external force, the lock cylinder 120 can be rotated along its axis P, thereby causing the lock cylinder 120 to rotate toward its locked position.
[0066] The following is combined Figure 2-3 , Figure 12 , Figure 16 As shown, in one embodiment of this application, the sleeve assembly 140 is mounted on the lock body 110 and always abuts against the abutment platform 126, and the sleeve assembly 140 always applies a downward force to the lock cylinder 120 (see...). Figure 12 , Figure 16 (as shown), thereby stably holding the lock cylinder 120 in the locked or unlocked position.
[0067] Combination Figure 3 , Figure 13 , Figure 17-18 As shown, in one specific embodiment, the sleeve assembly 140 includes at least a sleeve 141 and a first elastic member 142 installed within the sleeve 141. The sleeve 141 is movably mounted on the lock body 110 with one end protruding into the receiving cavity 111. Specifically, the sleeve 141 protrudes above the abutment platform 126. The elastic force of the first elastic member 142 ensures that the lower end of the sleeve 141 always abuts against the abutment platform 126. Therefore, when the latch portion 124 or the lock cylinder stop 125 abuts against the lock hook 150, the lock hook 150 applies an upward force to the lock cylinder 120, and the sleeve assembly 140 applies a downward force to the lock cylinder 120, thereby preventing the lock cylinder 120 from rotating and stably maintaining the lock cylinder 120 in the locked or unlocked position. Figure 13 , Figure 17-18 As shown. Additionally, when the lock cylinder 120 is subjected to external force... Figure 17-18 The release position shown is towards Figure 13 When the lock position is rotated, the elastic force of the first elastic element 142 also provides a driving force for the lock cylinder 120 to reset. That is, the elastic force of the first elastic element 142 to restore its deformation drives the lock cylinder 120 to rotate to its lock position, so that the lock cylinder 120 can be locked quickly.
[0068] Continue to combine Figure 3 , Figure 12As shown, in this specific embodiment, the sleeve assembly 140 further includes a plug cap 143, on which a positioning protrusion 144 protrudes. The plug cap 143 and the positioning protrusion 144 can be integrally formed or separately formed and then fixedly connected. The end of the first elastic member 142 away 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 cover plate 116 (see below for details) and positioning the upper end of the first elastic member 142 by 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 cylinder 120 rotating and pushing the sleeve 141 to move, the first elastic member 142 is less likely to deflect during the deformation process caused by the sleeve 141 squeezing the first elastic member 142.
[0069] In this embodiment, the first elastic element 142 is preferably a spring, but it is not limited to this, and other elastic elements can also be used.
[0070] The following is combined Figure 1-2 , Figure 10-18 As shown, in one embodiment of this application, the lock hook 150 includes a long lock hook rod 151 and a short lock hook rod 152, which are preferably integrally formed. The end face of the short lock hook rod 152 is provided with a lock hook end 1521. The long lock hook rod 151 is movably installed in the lock body 110 and extends into the receiving cavity 111. The bottom end of the long lock hook rod 151 is detachably engaged with the lock cylinder 120, so that the lock hook end 1521 of the short lock hook rod 152 can be inserted into the lock body 110 to realize the locking function or disengage from the lock body 110 to realize the unlocking function.
[0071] The following is combined Figure 2 , Figure 11 , Figure 15 As shown, in this embodiment, the bottom of the lock hook rod 151 is provided with a bottom end groove 1511, and a second elastic member 153 is provided in the bottom end groove 1511. 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 makes the lock hook rod 151 always tend to move towards the unlocking position, specifically, it makes the lock hook rod 151 always tend to move upward.
[0072] In this embodiment, the second elastic element 153 is preferably a spring, but it is not limited to this, and other elastic elements can also be used.
[0073] The following is combined Figure 11 , Figure 13 , Figure 15 , Figure 17-18As shown, in this embodiment, the end of the long locking rod 151 is provided with a locking platform 1512. The locking platform 1512 is arranged radially along the long locking rod 151 and has a ring structure. By abutting the locking platform 1512 with the locking hook part 124 and the lock cylinder stop 125 respectively, the locking hook 150 can be switched between the locked position and the unlocked position. Specifically, when the locking platform 1512 abuts against the abutting end 1241 of the locking hook part 124, the locking hook 150 is locked by the lock cylinder 120 and is in the locked position, such as... Figure 13 As shown, at this time, the long rod 151 of the lock hook compresses the second elastic element 153, causing it to deform. When the lock cylinder 120 rotates and the abutting end 1241 of the hook portion 124 disengages from the locking platform 1512, the second elastic element 153 restores its deformation and drives the long rod 151 of the lock hook to move upward until the locking platform 1512 abuts against the lower end face 1251 of the lock cylinder stop 125, as shown. Figure 17-18 As shown, at this time, the lock hook 150 moves to the unlock position, and the locking platform 1512 abuts against the lock cylinder stop 125 to prevent the elastic force of the second elastic member 153 from popping the lock hook rod 151 out of the lock body 110. That is, the lock cylinder stop 125 keeps the lock hook 150 in the unlock position and prevents it from disengaging from the lock body 110.
[0074] Continue to combine Figure 11 , Figure 13 , Figure 15 , Figure 17-18 As shown, in this embodiment, the end of the locking hook rod 151 is further provided with a pushing surface 1513. The pushing surface 1513 is arranged radially along the locking hook rod 151 and has a ring structure, and is located above the locking platform 1512. (See attached image) Figure 17-18 As shown, when the locking platform 1512 abuts against the lower end face 1251 of the lock cylinder stop 125, the pushing surface 1513 abuts against the upper end face 1252 of the lock cylinder stop 125. Thus, when the lock hook 150 is pressed downwards by external force, the pushing surface 1513 pushes the lock cylinder stop 125, thereby pushing the lock cylinder 120 to rotate towards its locked position. Furthermore, the lower end of the lock hook rod 151 again presses against the second elastic member 153, causing it to deform, until the lock cylinder 120 rotates to the locked position and locks the lock hook 150 again.
[0075] In this application, the locking hook 150 is preferably U-shaped, but it is not limited to this and it is also possible to set it to other shapes.
[0076] Let's combine them again below. Figures 2-3As shown, in one embodiment of this application, the upper surface of the lock body 110 is further provided with spaced-apart lock holes 113 and mounting holes 114, with the lock holes 113 communicating with the receiving cavity 111. The long hook rod 151 of the lock hook 150 is movably installed in the mounting hole 114. By moving the long hook rod 151, the hook end 1521 of the short hook rod 152 is inserted into or disengaged from the lock hole 113, thereby realizing the locking or unlocking function of the lock hook 150.
[0077] Combination Figure 1-3 As shown, in a preferred embodiment, the upper surface of the lock body 110 is further recessed with a main body groove 115, which is located between the mounting hole 114 and the lock hole 113. Furthermore, a sleeve through hole 1151 communicating with the receiving cavity 111 is also provided within the main body groove 115. The aforementioned sleeve assembly 140 is installed within this sleeve through hole 1151, specifically such that the first elastic member 142 and the sleeve 141 are both accommodated within the sleeve through hole 1151, and the lower end of the sleeve 141 protrudes onto the abutment platform 126. This structural arrangement makes the installation of the sleeve assembly 140 more convenient.
[0078] Continue to combine Figure 1-3 As shown, in a preferred embodiment, the stainless steel padlock 100 further includes a main cover plate 116, the shape of which corresponds to the shape of the main groove 115. The main cover plate 116 is detachably installed in the main groove 115. Furthermore, when the main cover plate 116 is installed, its upper surface is at the same level as the upper surface of the lock body 110.
[0079] See Figure 3 As shown, more preferably, the main cover plate 116 and the main groove 115 are provided with matching positioning posts 1161 and positioning holes 1152, which enable the detachable connection of the main cover plate 116. In one specific embodiment, two positioning holes 1152 are provided in the main groove 115, and the two positioning holes 1152 are arranged along the diagonal of the main groove 115. Correspondingly, two positioning posts 1161 are protruding along the diagonal of the main cover plate 116. The main cover plate 116 is installed by inserting the two positioning posts 1161 into the two positioning holes 1152, making the connection of the main cover plate 116 more stable when installed in the main groove 115.
[0080] In this application, the stainless steel padlock 100 is made of stainless steel, which makes its surface smooth and glossy, more textured, more beautiful in design, and has better wear resistance, aging resistance and impact resistance.
[0081] Let's combine them again below. Figures 1-18The working principle and process of the stainless steel padlock 100 of this utility model are explained as shown.
[0082] First combine Figure 1 , Figure 10-12 As shown, when unlocking is required, the correct key 160 is inserted into the lock cylinder 120. Specifically, the key body 162 is inserted into the hollow channel 131 of the lock cylinder sub-part 130, and the protrusion 1621 is inserted into the groove 132 of the sub-part. The key 160 is pushed inward, so that the key body 162 slides along the hollow channel 131 and the protrusion 1621 slides along the groove 132 of the sub-part, thereby smoothly inserting the key 160 into the lock cylinder 120.
[0083] See Figures 11-12 As shown, when the key body 162 is inserted into the inner cavity 121 of the lock cylinder 120, the end face recess 1622 on the key body 162 passes through the positioning post 123, thereby fastening the key body 162 and the lock cylinder 120 together and achieving positioning between them, allowing the key 160 to drive the lock cylinder 120 to rotate. At this time, the protrusion 1621 disengages from the sub-part groove 132 of the lock cylinder sub-part 130 and enters the lock cylinder groove 122. Furthermore, the protrusion 1621 and the lock cylinder groove 122 are mutually positioned in the radial direction of the lock cylinder 120. That is to say, the key 160 cannot rotate alone to disengage the protrusion 1621 from the lock cylinder groove 122. This further strengthens the positioning between the key body 162 and the lock cylinder 120 when the key 160 drives the lock cylinder 120 to rotate.
[0084] Combination Figure 14-18 As shown, when the key handle 161 rotates, causing the key body 162 to rotate, the key body 162 causes the lock cylinder 120 to rotate. During the lock cylinder 120's rotation to release the lock, its upper end's abutment platform 126 pushes the sleeve assembly 140 upward, thereby compressing the first elastic element 142 and deforming it, as shown... Figure 16 As shown. When the lock cylinder 120 rotates to the point where the abutting end 1241 of the latch portion 124 disengages from the latching platform 1512 of the lock hook 150, that is, the lock cylinder 120 rotates to the unlocking position, at which time the second elastic element 153 restores its deformation and drives the lock hook rod 151 to move upward until the latching platform 1512 abuts against the lower end face 1251 of the lock cylinder stop 125, as shown. Figure 17 As shown. At this time, the lock hook 150 moves to the unlocked position, and the locking platform 1512 abuts against the lock cylinder stop 125, thereby preventing the elastic force of the second elastic member 153 from ejecting the long lock hook 151 out of the lock body 110, while the lock hook end 1521 of the short lock hook 152 disengages from the key hole 113 and is in the unlocked state, as shown. Figures 14-16As shown. In this unlocked state, the elastic force generated by the first elastic element 142 of the sleeve assembly 140 acts downward on the lock cylinder 120, and the elastic force generated by the second elastic element 153 acts upward on the lock cylinder 120, as... Figure 17-18 As shown, this keeps the position of the lock cylinder 120 stable and keeps the lock cylinder 120 stably in the unlocked position.
[0085] See below. Figure 14-15 As shown, when the lock cylinder 120 is in the unlock position, its lock cylinder groove 122 rotates to be offset from the auxiliary part groove 132, so that the protrusion 1621 just abuts against the inner end face of the lock cylinder auxiliary part 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, its protrusion 1621 can abut against the lock cylinder auxiliary part 130 and prevent the key 160 from being pulled out, so that the key 160 is always kept on the lock body 110, improving the user experience.
[0086] Combined again Figure 10-14 , Figure 18 As shown, when relocking is required, the locking hook 150 is pushed downwards to move it downwards. During this process, the lower end of the locking hook rod 151 presses against the second elastic element 153 again, causing it to deform. At the same time, the pushing surface 1513 on the locking hook rod 151 pushes against the upper end surface 1252 of the lock cylinder stop 125, driving the lock cylinder 120 to rotate towards the locked position. During the rotation of the lock cylinder 120, the elastic force generated by the recovery deformation of the first elastic element 142 of the sleeve assembly 140 pushes against the abutment platform 126. Since the abutment platform 126 is offset from the axis P of the lock cylinder 120, it also pushes the lock cylinder 120 to rotate towards its locked position. That is, the first elastic element 142 drives the lock cylinder 120 to rotate and reset, thereby enabling the lock cylinder 120 to be rotated to the locked position quickly and effortlessly.
[0087] like Figure 10-13 As shown, when the lock cylinder 120 and key 160 are rotated to the locked position again, the second elastic element 153 is compressed again (see...). Figure 11 At the same time, the abutting end 1241 of the latch portion 124 on the lock cylinder 120 abuts against the latching platform 1512 again (see...). Figure 13 The locking hook 150 is engaged by the lock cylinder 120 and is in the locked position. At this time, the elastic force generated by the first elastic element 142 of the sleeve assembly 140 acts downward on the lock cylinder 120, and the elastic force generated by the second elastic element 153 acts upward on the lock cylinder 120, as shown. Figure 13 As shown, this keeps the lock cylinder 120 in the locked position, maintaining the stability of the locked state. The hook end 1521 of the short hook rod 152 is then inserted back into the lock hole 113 and is in a locked state, as shown. Figure 10-12 As shown.
[0088] Combined again Figure 1 , Figure 10-11 As shown, when the stainless steel padlock 100 is locked again, the key 160 is rotated to the position shown. Figure 10 In the state shown, the lock cylinder groove 122 on the lock cylinder 120 rotates again to the position corresponding to the auxiliary groove 132, and the two are connected along the axial direction of the lock cylinder 120, as shown. Figure 11 As shown, the protrusion 1621 is aligned with the groove 132 of the sub-part. The key 160 is pulled outward along the groove 132 of the sub-part, so that the key body 162 slides along the hollow channel 131 and the protrusion 1621 slides along the groove 132 of the sub-part, and the key 160 can be pulled out.
[0089] In summary, the stainless steel padlock 100 of this utility model adds a lock cylinder sub-component 130, which is fixed inside the lock body 110 and docks with the lock cylinder 120. The lock cylinder sub-component 130 has a hollow channel 131 extending axially along both ends of the lock cylinder sub-component 130. The hollow channel 131 allows the key 160 to slide and connect or disconnect from the lock cylinder 120. Thus, the key 160 can only drive the lock cylinder 120 to rotate by passing through the lock cylinder sub-component 130, and the lock cylinder sub-component 130 remains stationary during the rotation of the lock cylinder 120. Therefore, it is difficult to directly touch the lock cylinder 120 during use, and even if someone touches the lock cylinder sub-component 130, it will not cause the lock cylinder 120 to rotate. Compared with existing technologies, this effectively avoids the situation where the lock cylinder 120 is accidentally touched and rotated, thereby effectively preventing unintentional unlocking, improving locking security, and enhancing the user experience.
[0090] Other structures of the stainless steel padlock 100 involved in this utility model are all conventional structures well known to those skilled in the art, and will not be described in detail here.
