Description

Technical Field

[0001] The present invention relates to the technical field of padlocks, and particularly to a hardware padlock in which the key will not fall off in the unlocked state. 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 the 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 and is 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. Generally, in order to enhance the encryption function of the padlock, an encryption side (complex tooth pattern) is usually set on the surface of the key, and various encryption pins or thrust pins are added inside the lock body to achieve the effects of encrypted locking and unlocking, and at the same time prevent others from accidentally touching the lock core and rotating it to unlock. However, the setting of the encryption function makes the production process extremely complex, requires a large number of accessories, and has too high a cost, which is not conducive to commercial promotion and application. Secondly, 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, resulting in inconvenient use and reducing the user experience.

[0003] Therefore, it is necessary to provide a hardware padlock that can hold the key to prevent it from falling off in the unlocked state and has a simple structure and low cost to solve the above technical problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a hardware padlock that can hold the key to prevent it from falling off in the unlocked state and has a simple structure and low cost.

[0005] To achieve the above object, the technical solution of the present invention is as follows: A hardware padlock is provided, which includes a lock body, a lock core and a lock rod installed on the lock body, and further includes a stop post and a key that cooperates with the lock core; wherein, the stop post is fixed to the lock body and extends into the main cavity of the lock body; the lock core is rotatably installed in the main cavity, and a lock core through groove extending radially along the lock core is provided on the lock core, and the lock core through groove is rotationally matched with the stop post; at least two protrusions arranged axially along the outer surface of the key are convexly provided, and a card slot is formed between adjacent protrusions, and the card slot is rotationally matched with the stop post; when the key is inserted into the lock core, through the rotational cooperation of the lock core through groove, the card slot and the stop post, the key is allowed to drive the lock core to rotate to release or lock the lock rod, and after the lock core releases the lock rod, the card slot is engaged with the stop post to restrict the axial movement of the key along the lock core.

[0006] Preferably, the protrusions are provided on both side surfaces of the key that are opposite to each other along the plane passing through its axis, and at least two protrusions are provided on each side surface of the key. In this application, the traditional encrypted side structure on the key is cancelled, and instead, protrusions are respectively provided on both side surfaces. In this way, when inserting the key to unlock, if the key is incorrect, the protrusions on the key will be blocked and cannot be inserted into the lock core. Even if it is inserted into the lock core, it cannot be rotated to unlock due to the collision between the protrusions and the stop post, thereby achieving the effect of key encryption, and the structures of both the key and the interior of the lock body are simplified.

[0007] Preferably, the key includes a key handle and a key body connected to each other. The protrusion is provided on the key body. The key body is used to drive the lock core to rotate. When the key body is inserted into the lock core, the card slot is communicated with the lock core through groove, and the key handle is located outside the lock body for the user to operate.

[0008] Preferably, a lock core inner cavity extending axially along the lock core and penetrating one end thereof is further provided on the lock core. The lock core through groove is provided on the side wall of the lock core and communicates with the lock core inner cavity. When the key is inserted into the lock core inner cavity, one of the card slots is communicated with the lock core through groove. When the key drives the lock core to rotate, the card slot and the lock core through groove move along the stop post, and the stop post does not block the rotation and unlocking of the lock core, so that the lock core can be switched between the locked position and the unlocked position. When the lock core rotates to the unlocked position, the stop post just engages in the card slot, and thus abuts against the protrusion to prevent the axial movement of the key along the lock core.

[0009] Preferably, a positioning groove corresponding to the convex block is recessed on the inner end surface of the inner cavity of the lock core. When the key is inserted into the inner cavity of the lock core, the convex block is engaged in the positioning groove to achieve positioning.

[0010] Preferably, a lock core positioning post is provided on the inner end surface of the inner cavity of the lock core, and an end surface concave hole corresponding to the lock core positioning post is formed on the end surface of the key. When the key is inserted into the inner cavity of the lock core, the end surface concave hole is inserted outside the lock core positioning post, and the two are tightly fitted with each other, thereby realizing the positioning between the key and the lock core.

[0011] Preferably, at least one washer is sleeved on the lock core positioning post, and the washer has an elastic structure. When the end surface concave hole is inserted into the lock core positioning post, the washer is squeezed between the inner wall of the end surface concave hole and the lock core positioning post. This can prevent the key body from moving axially along the lock core positioning post. Therefore, even when the lock core is in the locked position, after the key is inserted into the lock core positioning post, it is not easy to fall off the lock body. Furthermore, the key can be held on the lock body when the lock core is in the locked position and the unlocking position, further improving the user experience.

[0012] Preferably, a groove extending radially along the lock core positioning post is recessed on the lock core positioning post, and the washer is engaged in the groove, making the installation of the washer more convenient and stable.

[0017] Preferably, the rotating snap - connection part is formed by extending downward from one end of the lock - core stopper, and when the end of the rotating snap - connection part far from the lock - core stopper abuts against the locking - latch end face, the lock rod is held in the locked position. When the lock core rotates to disengage the rotating snap - connection part from the locking - latch end face, the lock rod can move upward and the locking - latch end face abuts against the lower end of the lock - core stopper, holding the lock rod in the unlocked position.

[0018] Preferably, a pushing surface is further provided at the end of the long hook rod. The pushing surface is arranged above the locking - latch end face. When the locking - latch end face abuts against the lower end face of the lock - core stopper, the pushing surface abuts against the upper end face of the lock - core stopper. When the lock rod moves downward under an external force, the lock - core stopper is pushed by the pushing surface to drive the lock core to rotate towards the locked position.

[0019] Preferably, an installation hole and a lock hole are provided on the lock body at intervals. The long hook rod is movably installed in the installation hole, and by moving the long hook rod, the short hook rod is inserted into or disengaged from the lock hole.

[0020] Preferably, a bottom - end groove is further provided at the bottom of the long hook rod. A second elastic member is arranged in the bottom - end groove. The elastic force provided by the second elastic member makes the long hook rod always tend to move towards the unlocked position, and through the abutment of the locking - latch end face with the rotating snap - connection part and the lock - core stopper, the elastic force of the second elastic member is prevented from ejecting the long hook rod out of the lock body.

[0021] Preferably, a contact platform is further provided on the side wall of the lock core. The contact platform is arranged deviating from the axis line of the lock core. When the contact platform is subjected to an external force, the lock core can be rotated and reset towards the locked position along its axis line.

[0022] Preferably, the metal padlock further includes a sleeve assembly. The sleeve assembly is installed on the lock body and extends into the main - body cavity, and the sleeve assembly always abuts against the contact platform to hold the lock core in the locked position or the unlocked position.

[0023] Preferably, the sleeve assembly at least includes a sleeve and a first elastic member installed in the sleeve. The sleeve is installed in the lock body and corresponds to the contact platform. The elastic force of the first elastic member makes the sleeve always abut against the contact platform, so that when the rotating snap - connection part or the lock - core stopper abuts against the locking - latch end face, a force is provided to the lock core to keep the lock core stationary.

[0024] Preferably, the sleeve assembly also includes a plug cap and a positioning protrusion protruding from the plug cap, and the end of the first elastic member away from the sleeve is sleeved on the positioning protrusion and abuts against the plug cap. The first elastic member is positioned by the plug cap and the positioning protrusion, so that the first elastic member is not easily deflected when the lock core is rotated and squeezed and deformed.

[0025] Preferably, the hardware padlock further includes a lock core accessory, which is fixed in the lock body and docked with the lock core, and the lock core accessory is provided with a hollow channel and an accessory groove, the hollow channel extends along the axial direction of the lock core accessory and passes through both ends thereof, the accessory groove extends along the radial direction of the lock core accessory and communicates with the hollow channel, the hollow channel is used for the key to enter and exit the lock core, and the accessory groove is used for the protrusion to slide. The provision of the lock core accessory can prevent the lock core from rotating due to human error in touching the lock core, thereby causing non-subjective intentional unlocking, thereby improving the safety of locking and enhancing the user experience.

[0026] Preferably, two auxiliary component grooves are provided, and the two auxiliary component grooves are symmetrical along the center of the hollow channel.

[0027] Preferably, a main body groove is concavely formed on one end surface of the lock body, a stop column through hole communicating with the main body cavity is formed in the main body groove, and the stop column is fixed in the stop column through hole, so that the installation of the stop column is more convenient.

[0028] Preferably, a sleeve through hole communicating with the main body cavity is further provided in the main body groove, and the sleeve is installed in the sleeve through hole, so that the installation of the sleeve assembly is more convenient.

[0029] Preferably, the hardware padlock further includes a main body cover plate, the shape of the main body cover plate corresponds to the shape of the main body groove, and the main body cover plate is detachably installed in the main body groove.

[0030] Preferably, matching positioning posts and positioning holes are provided between the main body cover and the main body groove, and the detachable connection of the main body cover is achieved through the positioning posts and the positioning holes.

[0031] Preferably, when the main body cover is installed in the main body groove, the upper surface of the main body cover is on the same horizontal plane as the upper surface of the lock body.

[0032] Compared with the prior art, the hardware padlock of the present invention has the following technical effects: 1. A stop post is provided inside the lock body, and a keyway groove extending radially along the lock core is formed on the lock core. The keyway groove is rotationally engaged with the stop post. Then, at least two protrusions arranged axially are provided on the outer surface of the key, and a card slot is formed between adjacent protrusions. In this way, when the correct key is inserted into the lock core, the card slot on it communicates with the keyway groove, and both are rotationally engaged with the stop post, thereby allowing the key to drive the lock core to rotate and release the lock rod. After the lock core rotates to the unlocking position and releases the lock rod, the card slot on the key just engages with the stop post, thereby restricting the axial movement of the key along the lock core. This can prevent the key from accidentally falling off the lock body. At this time, even if the key is subjected to an outward pulling force, the protrusions on it can abut against the stop post to prevent the key from being pulled out, so that the key is always held on the lock body in the unlocked state. Only after the lock core rotates and locks again, the stop post disengages from the card slot, and the key can be pulled out, thus improving the user experience; 2. The traditional encrypted side structure is cancelled on the outer surface of the key, and protrusions with a certain distance are provided on the same side. In this way, when inserting the key, if the key is incorrect, the protrusions on the key will be blocked and cannot be inserted, or it will not be able to rotate and unlock due to the interference between the protrusions and the blocking post after being inserted into the lock core, thereby achieving the effect of key encryption. At the same time, the structures inside the key and the lock body are simplified, the number of parts is reduced, the production process is simplified, the production cost is reduced, and it is more conducive to commercial promotion and application.

[0060] 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 cannot be construed as a limitation to the present application. The first, second, etc. described are only used to distinguish technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0061] First, in combination with Figures 1 - 27 As shown, the hardware padlock 100 provided by the present application is particularly suitable for use in suitcases, storage lockers, luggage, door handles, etc., but is not limited thereto, and it is feasible to use it on any other items that need to be locked. First, in combination with Figures 1 - 3As shown, in an embodiment of the present application, the hardware padlock 100 includes a lock body 110, a stop post 120, a sleeve assembly 130, a lock core 140, a key 160, and a lock rod 170. Among them, a hollow main cavity 111 is provided inside the lock body 110, and the main cavity 111 communicates with the outside through a cavity inlet 112, and the cavity inlet 112 is provided on a side wall of the lock body 110. The lock core 140 is rotatably installed in the main cavity 111. A lock core inner cavity 141 is provided through one end in the axial direction of the lock core 140, and a lock core through groove 142 extending radially along the lock core 140 is also provided on the lock core 140, and the lock core through groove 142 communicates with the lock core inner cavity 141. The sleeve assembly 130 is installed on the lock body 110 and extends into the main cavity 111 to abut against the lock core 140, and is used to hold the lock core 140 in the locked position or the unlocked position, as will be described later. The key 160 cooperates with the lock core 140 and is used to drive the lock core 140 to transform from the locked position to the unlocked position. The lock rod 170 is movably installed on the lock body 110 and cooperates with the lock core 140. The lock core 140 locks and can unlock the lock rod 170.

[0062] Combined with Figures 1 - 2 , Figures 16 - 17 , Figures 21 - 23 As shown, in this embodiment, the stop post 120 is fixed to the lock body 110 and extends into the lock core through groove 142, and the stop post 120 is rotationally matched with the lock core through groove 142. At the same time, at least two protrusions 1621 arranged axially are convexly provided on the outer surface of the key 160, a card slot 1622 is formed between two adjacent protrusions 1621, and the card slot 1622 can be rotationally matched with the stop post 120. Specifically, when the key 160 is inserted into the lock core 140, the card slot 1622 communicates with the lock core through groove 142 and is rotationally matched with the stop post 120, as Figures 16 - 17 shown, so as to allow the key 160 to drive the lock core 140 to rotate and release the lock rod 170. As Figures 21 - 23 shown, when the lock core 140 releases the lock rod 170, the key 160 and the lock core 140 rotate until the card slot 1622 is engaged with the stop post 120, thereby restricting the axial movement of the key 160 along the lock core 140. Thus, when the hardware padlock 100 is in the unlocked state, the key 160 can be held, thereby preventing the key 160 from falling and improving the user experience.

[0063] Next, combined with Figures 2 - 3 shown, in an embodiment of the present application, a stop portion 121 is formed at the lower end of the stop post 120, and the outer diameter of the stop portion 121 is smaller than the outer diameters of other parts of the stop post 120. Combined with Figures 16 - 17As shown, the outer diameter of the stop portion 121 is smaller than the widths of the lock core through groove 142 and the clamping groove 1622. In this way, after the stop post 120 and the lock core 140 are installed, the stop portion 121 protrudes into the lock core through groove 142, and when the lock core 140 rotates, the lock core through groove 142 can move along the stop portion 121, so as not to block the rotation of the lock core 140, realizing the rotational cooperation between the stop post 120 and the lock core 140.

[0064] Continue to combine Figures 1 - 2 As shown, in an embodiment of the present application, bumps 1621 are provided on both opposite side surfaces of the key 160. The so-called opposite side surfaces refer to the two opposite side surfaces along the plane passing through its axis P1, and this plane is perpendicular to the plane where the key handle 161 (see below) is located, as Figure 1 shown. Moreover, the bumps 1621 provided on both side surfaces of the key 160 are symmetric with respect to the plane passing through its axis P1, and at least two bumps 1621 are provided on each side surface of the key 160. For example, in a specific embodiment, the bumps 1621 on both side surfaces are symmetrically arranged up and down along the plane passing through the axis P1, and three bumps 1621 are provided on each side surface of the key 160. Two clamping grooves 1622 are respectively formed between the three bumps 1621, and the three bumps 1621 can be evenly arranged or unevenly arranged. Of course, in other embodiments, more bumps 1621 can be provided on each side surface of the key 160.

[0065] Next, combine with Figure 1 - 2, Figures 14 - 15 As shown, in this embodiment, 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 core 140 and drive the lock core 140 to rotate, and the key handle 161 is used for the user to operate. More preferably, the key body 162 is generally in a cylindrical structure. Of course, the key body 162 can also be set to other shapes. An end face concave hole 1623 is formed in the end face of the key body 162, and the end face concave hole 1623 extends along the axial direction of the key body 162, as Figures 14 - 15 shown. Bumps 1621 protrude from both opposite side surfaces of the key body 162. The so-called opposite side surfaces here refer to the two opposite side surfaces along the plane passing through the axis P1 of the key body 162, as Figure 1As shown, when the key body 162 is inserted into the lock core 140, it is connected to the inside of the lock core 140 through the end face concave hole 1623 (details will be described later). Moreover, one of the card slots 1622 communicates with the lock core through slot 142. 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 140 is driven to rotate. Also, the card slot 1622 and the lock core through slot 142 can move along the stop portion 121 without blocking the rotation of the lock core 140 and the key 160.

[0066] The following is combined with Figures 4 - 5 、 Figure 8 As shown, in an embodiment of the present application, the lock core inner cavity 141 extends along the axial direction of the lock core 140 and penetrates one end thereof. The lock core through slot 142 is opened on the side wall of the lock core 140 and communicates with the lock core inner cavity 141. The lock core through slot 142 has an arc-shaped structure. Also, a lock core positioning post 143 is provided on the inner end face of the lock core inner cavity 141. The lock core positioning post 143 extends along the axial direction of the lock core 140 and protrudes outside the lock core 140 (see Figure 4 、 Figure 8 shown). The outer diameter of the lock core positioning post 143 is matched with the end face concave hole 1623 provided on the key body 162. Combining Figures 14 - 15 shown, when the key body 162 is inserted into the lock core inner cavity 141, the lock core positioning post 143 is inserted into the end face concave hole 1623 and the two are tightly fitted, thereby fixing the key body 162 and realizing the positioning between the key body 162 and the lock core 140, so that the key 160 can drive the lock core 140 to rotate.

[0067] Combining Figures 15 - 17 shown, when the lock core 140 is in the locked position, the card slot 1622 on the key body 162 inserted into the lock core 140 communicates with the lock core through slot 142. Moreover, the card slot 1622 on the key body 162 is misaligned with the stop post 120 (see Figure 16 ). When the key body 162 drives the lock core 140 to rotate, the card slot 1622 and the lock core through slot 142 move along the stop post 120 until the lock core 140 rotates to the unlocking position. Therefore, the stop post 120 does not interfere with the rotation and unlocking of the lock core 140. Combining Figures 19 - 22 shown, when the key body 162 drives the lock core 140 to rotate to the unlocking position and releases the lock rod 170, the card slot 1622 on the key body 162 turns to the position where it is engaged with the stop post 120, that is to say, the stop post 120 is engaged in one of the card slots 1622 (see Figure 19), thereby preventing the key body 162 from axially sliding along the lock core 140 and falling off, so that the key 160 can always be held on the lock body 110, effectively preventing the key 160 from accidentally falling. At this time, even if the key 160 is subjected to an outward pulling force, the bump 1621 thereon can abut against the stop post 120 to prevent the key 160 from being pulled out, so that the key 160 is always held on the lock body 110 in the unlocked state. Only when the lock core 140 rotates to the locked position again, the stop post 120 and the card slot 120 will be disengaged again, and the key 160 can be pulled out, thereby improving the user experience.

[0068] The following will be combined with Figures 14 - 15 , Figures 19 - 20 As shown, in a preferred embodiment, one end of the lock core positioning post 143 is provided with a connecting thin rod 1431, and a concave cavity connecting hole 1411 corresponding to the connecting thin rod 1431 is opened on the inner end surface of the lock core inner cavity 141. The connecting thin rod 1431 is inserted into the concave cavity connecting hole 1411 (see Figure 15 ) and is tightly fitted, so as to realize the fixed installation of the lock core positioning post 143 and make the installation of the lock core positioning post 143 more convenient. Of course, it is also feasible to install the lock core positioning post 143 by other means.

[0069] The following will be combined with Figure 5 , Figure 15 As shown, in another preferred embodiment, a positioning groove 144 corresponding to the shape of the bump 1621 is further concavely provided on the inner end surface of the lock core inner cavity 141. When the key body 162 is inserted into the lock core positioning post 143, the bump 1621 just engages in the positioning groove 144, further strengthening the positioning between the key body 162 and the lock core 140, so that the key body 162 can more effectively drive the lock core 140 to rotate.

[0070] Of course, the positioning groove 144 and the lock core positioning post 143 can also be provided on the inner end surface of the lock core inner cavity 141 at the same time, so as to strengthen the positioning between the key body 162 and the lock core 140 in the radial direction (rotation direction), making it easier for the key 160 to drive the lock core 140 to rotate.

[0071] The following will be combined with Figures 6 - 7 As shown, in an embodiment of the present application, a rotary clamping portion 145 and a lock core stopper 146 are further provided at one end of the lock core 140 away from the lock core through groove 142. Among them, the rotary clamping portion 145 and the lock core stopper 146 are both provided on the end surface of the lock core 140 and have a height difference. Specifically, the lock core stopper 146 is located above the rotary clamping portion 145. By rotating the lock core 140, the rotary clamping portion 145 and the lock core stopper 146 can respectively abut against the lock rod 170, so as to hold the lock rod 170 in the locked position and the unlocked position.

[0072] As shown in combination with Figures 6 - 7 , Figure 17 , Figure 22 in a specific embodiment, the lock core stopper 146 extends substantially along the diameter direction of the end face of the upper edge lock core 140, and the lock core stopper 146 has a lower end face 1461 with a curved surface and an upper end face 1462 with a planar structure, as Figure 7 shown. The top end of the rotary engaging portion 145 is connected to one end of the lock core stopper 146. The rotary engaging portion 145 extends downward from the lock core stopper 146 and has an arc-shaped structure. An abutting end 1451 is formed at the bottom end of the rotary engaging portion 145 away from the lock core stopper 146. Combining Figure 17 , Figure 22 shown, when the abutting end 1451 of the rotary engaging portion 145 abuts against the lock rod 170, the lock rod 170 is held in the locked position, as Figure 17 shown. When the lock core 140 rotates and the abutting end 1451 of the rotary engaging portion 145 disengages from the lock rod 170, the lock rod 170 can move upward and abut against the lower end face 1461 of the lock core stopper 146, thereby holding the lock rod 170 in the unlocked position, as Figure 22 shown.

[0073] As shown in combination with Figures 4 - 9 in an embodiment of the present application, an abutting platform 147 is further provided on the side wall of the lock core 140. The abutting platform 147 is formed by recessing from the outer surface of the lock core 140, and the abutting platform 147 is disposed offset from the axis line P2 of the lock core 140. Specifically, the inner edge of the abutting platform 147 is at a certain distance from the axis line P2 of the lock core 140, and moreover, the abutting platform 147 and the lock core through slot 142 are located on both sides of the axis line P2 of the lock core 140, as Figure 4 , Figure 9 shown. In this way, when an external force is applied to the abutting platform 147, the lock core 140 can be rotated along its axis line P2 to the locked position.

[0074] As shown in combination with Figures 2 - 3 , Figure 13 in this embodiment, the sleeve assembly 130 is installed on the lock body 110 and always abuts against the abutting platform 147. The sleeve assembly 130 always applies a downward force to the lock core 140 (see Figure 13 shown), thereby holding the lock core 140 in the locked position or the unlocked position.

[0075] In a specific embodiment, the sleeve assembly 130 at least includes a sleeve 131 and a first elastic member 132 disposed within the sleeve 131. The sleeve 131 is movably mounted on the lock body 110 and protrudes above the abutting platform 147. The elastic force of the first elastic member 132 causes the lower end of the sleeve 131 to always abut against the abutting platform 147. Thus, when the rotary engaging portion 145 or the lock core stopper 146 abuts against the lock rod 170, the sleeve assembly 130 applies a downward force to the lock core 140 to keep the lock core 140 stationary, so that the lock core 140 is stably maintained in the locked position or the unlocked position, as Figure 17 , Figure 23 shown. Additionally, when the lock core 140 is rotated from the unlocked position shown in Figure 23 to the locked position shown in Figure 17 under the action of an external force, the elastic force of the first elastic member 132 also provides a driving force for the lock core 140 to reset. That is, the elastic force of the first elastic member 132 recovering from deformation drives the lock core 140 to rotate and reset to the locked position.

[0076] More specifically, the sleeve assembly 130 further includes a plug cap 133. The plug cap 133 is provided with a positioning projection 134 protruding therefrom. The plug cap 133 and the positioning projection 134 can be integrally formed or fixedly connected after being separately formed. One end of the first elastic member 132 away from the sleeve 131 is sleeved on the positioning projection 134 and abuts against the plug cap 133. Specifically, the upper end of the first elastic member 132 is sleeved on the positioning projection 134 and abuts against the plug cap 133. By connecting the plug cap 133 to the main body cover plate 119 (see details below) and positioning the upper end of the first elastic member 132, not only is the installation of the first elastic member 132 more convenient, but also the first elastic member 132 is not easily deflected during the process that the lock core 140 rotates and pushes the sleeve 131 to squeeze the first elastic member 132.

[0077] In this embodiment, the first elastic member 132 is preferably a spring, but is not limited thereto. Of course, other elastic components can also be selected.

[0078] Next, with reference to Figures 12 - 23 shown, in an embodiment of the present application, the lock rod 170 includes a lock hook long rod 171 and a lock hook short rod 172, and the lock hook long rod 171 and the lock hook short rod 172 are integrally formed. The end face of the lock hook short rod 172 is provided with a lock rod end portion 1721. The lock hook long rod 171 is movably mounted on the lock body 110 and extends into the main body cavity 111. The bottom end of the lock hook long rod 171 is detachably engaged with the lock core 140. Thus, the lock rod end portion 1721 of the lock hook short rod 172 is inserted into the lock body 110 to achieve the locking function or disengaged from the lock body 110 to achieve the unlocking function.

[0079] Next, with reference to Figures 14 - 15 ,Figure 17 , Figures 19 - 23 As shown in Figures 19 - 23 , in this embodiment, a bottom groove 1711 is provided at the bottom of the locking hook long rod 171, and a second elastic member 173 is provided in the bottom groove 1711. The other end of the second elastic member 173 abuts against the lock body 110. The elastic force provided by the second elastic member 173 causes the locking hook long rod 171 to always have a tendency to move towards the unlocking position. Specifically, the locking hook long rod 171 always has an upward movement tendency.

[0080] In this embodiment, the second elastic member 173 is preferably a spring, but is not limited thereto. Of course, other elastic components can also be selected.

[0081] Continuing to refer to Figures 14 - 15 , Figure 17 , Figures 19 - 23 As shown in Figures 14 - 15 , Figure 17 , and Figures 19 - 23 , in this embodiment, a locking end face 1712 is provided at the end of the locking hook long rod 171. The locking end face 1712 is arranged along the radial direction of the locking hook long rod 171 and has an annular structure. By the abutment of the locking end face 1712 with the rotary engaging portion 145 and the lock core stopper 146 respectively, the switching of the lock rod 170 between the locking position and the unlocking position is realized. Specifically, when the locking end face 1712 abuts against the abutting end 1451 of the rotary engaging portion 145, the lock rod 170 is locked by the lock core 140 and is in the locking position. As shown in Figure 17 , at this time, the locking hook long rod 171 presses the second elastic member 173 to cause it to deform. When the lock core 140 rotates to make the abutting end 1451 of the rotary engaging portion 145 disengage from the locking end face 1712, the second elastic member 173 recovers its deformation and drives the locking hook long rod 171 to move upward until the locking end face 1712 abuts against the lower end face 1461 of the lock core stopper 146. As shown in Figures 19 - 20 and Figures 22 - 23 , at this time, the lock rod 170 moves to the unlocking position, and the locking end face 1712 abuts against the lock core stopper 146, preventing the elastic force of the second elastic member 173 from ejecting the locking hook long rod 171 out of the lock body 110. That is, the lock core stopper 146 holds the lock rod 170 in the unlocking position to prevent it from disengaging from the lock body 110. Figure 17 As shown in Figure 17 , at this time, the locking hook long rod 171 presses the second elastic member 173 to cause it to deform. When the lock core 140 rotates to make the abutting end 1451 of the rotary engaging portion 145 disengage from the locking end face 1712, the second elastic member 173 recovers its deformation and drives the locking hook long rod 171 to move upward until the locking end face 1712 abuts against the lower end face 1461 of the lock core stopper 146. As shown in Figures 19 - 20 and Figures 22 - 23 , at this time, the lock rod 170 moves to the unlocking position, and the locking end face 1712 abuts against the lock core stopper 146, preventing the elastic force of the second elastic member 173 from ejecting the locking hook long rod 171 out of the lock body 110. That is, the lock core stopper 146 holds the lock rod 170 in the unlocking position to prevent it from disengaging from the lock body 110. Figures 19 - 20 , Figures 22 - 23 As shown in Figures 19 - 20 and Figures 22 - 23 , at this time, the lock rod 170 moves to the unlocking position, and the locking end face 1712 abuts against the lock core stopper 146, preventing the elastic force of the second elastic member 173 from ejecting the locking hook long rod 171 out of the lock body 110. That is, the lock core stopper 146 holds the lock rod 170 in the unlocking position to prevent it from disengaging from the lock body 110.

[0082] Continuing to refer to Figures 14 - 15 , Figure 17 , Figures 19 - 23 As shown in Figures 14 - 15 , Figure 17 , and Figures 19 - 23 , in this embodiment, a pushing face 1713 is further provided at the end of the locking hook long rod 171. The pushing face 1713 is arranged along the radial direction of the locking hook long rod 171 and has an annular structure, and the pushing face 1713 is provided above the locking end face 1712. Refer to Figures 22 - 23As shown, when the end face 1712 of the latch abuts against the lower end face 1461 of the lock core stopper 146, the pushing face 1713 just abuts against the upper end face 1462 of the lock core stopper 146. In this way, when the lock rod 170 is extruded downward by an external force, the lock core stopper 146 is pushed by the pushing face 1713 to drive the rotation of the lock core 140, and the lower end of the long latch rod 171 presses the second elastic member 173 again to deform it until the lock core 140 rotates to the locked position.

[0083] In the present application, the lock rod 170 preferably has a U-shaped structure, but is not limited thereto, and it is also feasible to set it to other shapes.

[0084] As shown in the following in conjunction with Figures 1 - 2 , Figures 10 - 11 In an embodiment of the present application, the hardware padlock 100 further includes a lock core sub-component 150, which is fixed in the main cavity 111 of the lock body 110 and is docked with the lock core 140. Specifically, the lock core sub-component 150 is provided with a hollow channel 151 and a sub-component groove 152. The hollow channel 151 extends along the axis of the lock core sub-component 150 and penetrates through both ends thereof. The sub-component groove 152 extends along the radial direction of the lock core sub-component 150 and communicates with the hollow channel 151, and there is at least one sub-component groove 152, which is specifically set according to the protrusions 1621 provided on the key body 162. The hollow channel 151 is used for the key body 162 to slide, and the sub-component groove 152 is used for the protrusions 1621 to slide, so that the key 160 can smoothly enter and exit the lock core 140. The setting of the lock core sub-component 150 can prevent people from accidentally touching the lock core 140 and causing the lock core 140 to rotate, thereby causing unlocking against the subjective will, thus improving the locking security and enhancing the user experience.

[0085] Continuing to combine with Figures 10 - 11 As shown, in a specific embodiment, the lock core sub-component 150 is provided with two symmetric sub-component grooves 152 for the protrusions 1621 provided on both side faces of the key body 162 to slide. Combining with Figures 12 - 13 As shown, after the lock core sub-component 150 is fixed in the main cavity 111, the lock core sub-component 150 is just located in the cavity inlet 112, and the end of the lock core sub-component 150 provided with the sub-component groove 152 is flush with the side face of the lock body 110 (see Figure 1 , Figure 12 ), and the hollow channel 151 communicates with the lock core inner cavity 141 (see Figure 14). When the key 160 is inserted, the key body 162 slides along the hollow channel 151. At the same time, the convex block 1621 is correspondingly inserted into the accessory groove 152 and slides along the accessory groove 152, so that the key 160 can smoothly enter the lock core 140. In other embodiments, the number and position of the accessory grooves 152 are flexibly set according to the position of the convex blocks 1621 provided on the key body 162.

[0086] Next, in combination with Figures 2 - 3 , Figures 14 - 15 , Figures 19 - 20 shown, in an embodiment of the present application, the upper surface of the lock body 110 is further provided with spaced installation holes 113 and a lock hole 114, and the installation hole 113 communicates with the main body cavity 111. The lock hook long rod 171 of the lock rod 170 is movably installed in the installation hole 113, and the lock rod end 1721 of the lock hook short rod 172 is inserted into the lock hole 114 (as shown in Figures 14 - 15 ) or disengaged from the lock hole 114 (as shown in Figures 19 - 20 ) through the movement of the lock hook long rod 171, so as to realize the locking function or unlocking function of the lock rod 170.

[0087] Combined with Figures 1 - 3 shown, in a preferred embodiment, a main body groove 115 is further recessed on the upper surface of the lock body 110, and the main body groove 115 is provided between the installation hole 113 and the lock hole 114. Moreover, the hardware padlock 100 further includes a main body cover plate 119, and the shape of the main body cover plate 119 corresponds to the shape of the main body groove 115. The main body cover plate 119 is detachably installed in the main body groove 115. When the main body cover plate 119 is installed, the upper surface of the main body cover plate 119 is on the same horizontal plane as the upper surface of the lock body 110.

[0088] Next, in combination with Figures 13 - 14 shown, a sleeve through hole 116 and a stop post through hole 117 communicating with the main body cavity 111 are further opened in the main body groove 115. Among them, the sleeve assembly 130 is installed in the sleeve through hole 116, the lower end of its sleeve 131 protrudes from the sleeve through hole 116 and abuts against the abutting platform 147, and its plug cap 133 is fixed to the main body cover plate 119, as shown in Figure 13 . The stop post 120 is arranged in the stop post through hole 117 and is fixed to the main body cover plate 119 by welding, bonding or other means, and the lower stop portion 121 protrudes from the stop post through hole 117 and is located in the lock core through groove 142, as shown in Figure 14 . This structural setting makes the installation of the stop post 120 and the sleeve assembly 130 more convenient.

[0089] Continuing to combine Figures 2 - 3 , Figures 13 - 14As shown, in a preferred embodiment, a positioning post 1191 and a positioning hole 118 are provided between the main body cover plate 119 and the main body groove 115, and the detachable connection of the main body cover plate 119 is realized through the positioning post 1191 and the positioning hole 118. In a specific embodiment, two positioning holes 118 are provided in the main body groove 115, and the two positioning holes 118 are arranged along the diagonal line of the main body groove 115. Correspondingly, two positioning posts 1191 protrude from the diagonal line of the main body cover plate 119, and the main body cover plate 119 is installed by inserting the two positioning posts 1191 into the two positioning holes 118, making the connection more stable when the main body cover plate 119 is installed in the main body groove 115.

[0090] In this application, the hardware padlock 100 is preferably made of titanium alloy, aluminum alloy or other alloys, so that the surface of the hardware padlock 100 is smooth and shiny, more textured, more beautiful in design, and has better wear resistance, anti-aging property and impact resistance.

[0091] Next, in combination with Figures 24 - 27 As shown, in another embodiment of this application, the structure of the hardware padlock 100 is different from that in the above Figures 1 - 23 shown embodiment only in that: at least one washer 148 is sleeved on the lock core positioning post 143, and the washer 148 has an elastic structure. For example, in the Figures 24 - 25 shown specific embodiment, two washers 148 are sleeved on the lock core positioning post 143 at intervals. With this structural arrangement, when the end face concave hole 1623 of the key body 162 is inserted into the lock core positioning post 143, the washer 148 is squeezed between the lock core positioning post 143 and the inner wall of the end face concave hole 1623 (see Figure 27 ), which can prevent the key body 162 from moving axially along the lock core positioning post 143, thereby strengthening the stability of the connection of the key body 162. In this way, even when the lock core 140 is in the locked position, the key 160 inserted into the lock core positioning post 143 is not easily detached from the lock body 110, so that the key 160 can be held on the lock body 110 both when the lock core 140 is in the locked position and the unlocking position, further improving the user experience.

[0092] Continuing to combine Figures 24 - 27As shown, in a preferred embodiment, a groove 1432 is recessed in the lock core positioning post 143. The groove 1432 is arranged along the radial direction of the lock core positioning post 143. The washer 148 is engaged in the groove 1432, making the installation of the washer 148 more convenient and stable. More preferably, at least one exhaust groove 1433 is further formed on the lock core positioning post 143. The exhaust groove 1433 is formed by the depression of the surface of the lock core positioning post 143 and extends along the axial direction of the lock core positioning post 143. The exhaust groove 1433 communicates with each groove 1432. More specifically, the groove 1432 is formed in the approximate middle of the exhaust groove 1433 and intersects with the exhaust groove 1433 to communicate with each other (see Figure 26 ). With this structural arrangement, during the process of inserting the key body 162 into the lock core positioning post 143, air can be exhausted when the washer 148 is squeezed, so that the key body 162 can be more easily inserted into the lock core positioning post 143.

[0093] In this embodiment, the structures of other parts of the hardware padlock 100 are the same as those in the Figures 1 - 23 shown embodiment, so they will not be repeated here.

[0094] Next, with reference to Figures 1 - 27 shown again, the working principle and process of the hardware padlock 100 of the present application will be described.

[0095] First, with reference to Figure 1 , Figure 12 shown, when unlocking is required, the correct key 160 is inserted into the lock core 140. Specifically, the key body 162 is inserted into the hollow channel 151 of the lock core accessory 150, and at the same time, the convex block 1621 is inserted into the accessory groove 152. Then, the key 160 is pushed, so that the key body 162 slides along the hollow channel 151, and its convex block 1621 slides along the accessory groove 152, so that the key 160 can be smoothly slid into the lock core 140, as Figure 12 shown.

[0096] With reference to Figures 14 - 15 shown, when the key 160 is inserted into the lock core inner cavity 141 of the lock core 140, the end face concave hole 1623 on the key body 162 is just inserted into the lock core positioning post 143 and achieves a tight fit, thereby fixing the key body 162 and realizing the positioning between the key body 162 and the lock core 140. At the same time, the convex block 1621 at the end of the key body 162 is just engaged in the positioning groove 144 on the inner end face of the lock core inner cavity 141, further strengthening the radial positioning between the key body 162 and the lock core 140. With reference to Figures 16 - 17 shown, at this time, a card slot 1622 between the convex blocks 1621 is communicated with the lock core through slot 142 (see Figure 15), the position of the card slot 1622 is offset from that of the stop portion 121 (see Figures 16 - 17 ), so that the key 160 can drive the lock core 140 to rotate.

[0097] Furthermore, after the end face concave hole 1623 of the key body 162 is inserted into the lock core positioning post 143, the washer 148 is squeezed between the inner wall of the end face concave hole 1623 and the lock core positioning post 143, as Figure 27 shown, which can prevent the key body 162 from moving axially along the lock core positioning post 143. At this time, although the lock core 140 is still in the locked position, it can still prevent the key 160 just inserted on the lock core positioning post 143 from falling off the lock body 110, thereby improving the user experience.

[0098] Combined with Figures 18 - 23 shown, when the key handle 161 is rotated to drive the key body 162 to rotate, the key body 162 drives the lock core 140 to rotate. During this process, the card slot 1622 and the lock core through slot 142 can move along the stop portion 121, and the stop portion 121 does not block the rotation of the lock core 140 and the key 160. The state where the key 160 is rotated to the unlocking position is as Figure 18 shown.

[0099] During the unlocking process of the lock core 140, the abutting platform 147 at its upper end pushes the sleeve 131 of the sleeve assembly 130 upward, thereby squeezing the first elastic member 132 to deform it. When the lock core 140 rotates to make the abutting end 1451 of the rotary engaging portion 145 disengage from the locking end face 1712 of the lock rod 170, the second elastic member 173 restores its deformation and drives the lock hook long rod 171 upward until the locking end face 1712 abuts against the lower end face 1461 of the lock core stopper 146, as Figures 19 - 20 、 Figures 22 - 23 shown. At this time, the lock rod 170 moves to the unlocking position, and the locking end face 1712 abuts against the lock core stopper 146, thereby preventing the elastic force of the second elastic member 173 from ejecting the lock hook long rod 171 out of the lock body 110, and the lock rod end portion 1721 of the lock hook short rod 172 disengages from the lock hole 113 and is in the unlocking state, as Figures 18 - 20 shown. At this time, the elastic force generated by the second elastic member 173 acts upward on the lock core 140, and the elastic force generated by the first elastic member 132 of the sleeve assembly 130 acts downward on the lock core 140, so that the lock core 140 remains stationary, thereby stably holding the lock core 140 in the unlocking position.

[0100] As Figures 18 - 21 shown, at the unlocking position, the card slot 1622 on the key body 162 rotates to a position where it is engaged with the stop post 120, that is, the stop post 120 is engaged in a card slot 1622 (see Figure 19 、 Figure 21As shown, this prevents the key body 162 from axially sliding along the lock core 140 and falling off. Even if an outward pulling force is applied to the key 160, the convex block 1621 thereon can abut against the stop post 120 to prevent the key 160 from being pulled out. Thus, the key 160 is always held on the lock body 110 in the unlocked state, effectively preventing the key 160 from accidentally falling off and further enhancing the user experience.

[0101] That is to say, after the key 160 is inserted into the lock core 140 in this application, whether the lock core 140 is in the locked state or has been rotated to the unlocked state, the key 160 can be held on the lock body 110, effectively preventing the key 160 from accidentally falling off, thereby greatly enhancing the user experience.

[0102] Combined with Figures 18 - 20 As shown, when it is necessary to lock again, push the lock rod 170 downward to make it move downward. During this process, the lower end of the lock hook long rod 171 presses the second elastic member 173 again to deform it. At the same time, the pushing surface 1713 on the lock hook long rod 171 pushes the lock core stopper 146 to drive the lock core 140 to rotate towards the locked position. During the rotation of the lock core 140, the elastic force generated by the restoration of the deformation of the first elastic member 132 of the sleeve assembly 130 pushes the abutting platform 147, further pushing the lock core 140 to rotate and reset to the locked position, so that the lock core 140 can be quickly and labor-savingly rotated to the locked position. During the rotation of the lock core 140, the lock core through groove 142 thereon and the card slot 1622 on the key 160 also move along the stop portion 121, and the stop portion 121 does not block the rotation of the lock core 140 and the key 160.

[0103] As Figures 16 - 17 shown, when the lock core 140 and the key 160 are rotated to the locked position again, the second elastic member 173 is compressed again. At this time, the abutting end 1451 of the rotation engaging portion 145 on the lock core 140 abuts against the latch end face 1712, and the lock rod 170 is abutted by the lock core 140 and is in the locked position. At the same time, the elastic force generated by the second elastic member 173 acts upward on the lock core 140, and the elastic force generated by the first elastic member 132 of the sleeve assembly 130 acts downward on the lock core 140, thereby stably holding the lock core 140 in the locked position. And the lock rod end 1721 of the lock hook short rod 172 is inserted into the lock hole 113 again and is in the locked state, as Figures 12 - 15 shown.

[0104] Combined with Figure 1 、 Figure 12 shown, when the hardware padlock 100 is locked again, the key 160 is rotated to as Figure 12The state shown is when the card slot 1622 on it rotates to disengage from the stop portion 121, and the bump 1621 corresponds to the position of the accessory groove 152. In this state, since the washer 148 is squeezed between the key body 162 and the lock core positioning post 143, the key body 162 is not easily slid outwards, preventing the key 160 from falling off the lock body 110. When pulling out the key 160, a relatively large pulling force needs to be applied to pull the key 160 outwards, so that the key body 162 slides along the hollow channel 151 and the bump 1621 slides along the accessory groove 152 to pull out the key 160. Of course, for the embodiment without the washer 148, a relatively small force is applied to pull the key 160 outwards to pull it out.

[0105] Combined with the above description, the hardware padlock 100 of the present invention has the following technical effects: First, a stop post 120 is provided inside the lock body 110, and a lock core through groove 142 extending radially along the lock core 140 is opened on the lock core 140, so that the lock core through groove 142 is rotationally engaged with the stop post 120. Then, at least two bumps 1621 arranged axially are convexly provided on the outer surface of the key 160, and a card slot 1622 is formed between adjacent bumps 1621. In this way, when the correct key 160 is inserted into the lock core 140, the card slot 1622 on it communicates with the lock core through groove 142 and both are rotationally engaged with the stop post 120, allowing the key 160 to drive the lock core 140 to rotate and release the lock rod 170. When the lock core 140 rotates to the unlocking position and releases the lock rod 170, the card slot 1622 on the key 160 just engages with the stop post 120, restricting the axial movement of the key 160 along the lock core 140. Thus, the key 160 can be prevented from accidentally falling off the lock body 110. At this time, even if the key 160 is subjected to an outward pulling force, the bump 1621 on it can abut against the stop post 120 to prevent the key 160 from being pulled out, so that the key 160 is always held on the lock body 110 in the unlocked state. Only after the lock core 140 rotates and locks again, the stop post 120 disengages from the card slot 1622, and the key 160 can be pulled out, thus improving the user experience. Second, the traditional encrypted side structure on the outer surface of the key 160 is cancelled, and bumps 1621 with a certain spacing are provided on the same side. In this way, when inserting the key 160, if the key 160 is incorrect, the bumps 1621 on the key 160 will be blocked and cannot be inserted, or after being inserted into the lock core 140, it cannot be rotated to unlock due to the interference between the bump 1621 and the stop post 120, thus achieving the effect of encrypting the key 160. At the same time, the structures inside the key 160 and the lock body 110 are simplified, the number of accessories is reduced, the production process is simplified, the production cost is reduced, and it is more conducive to commercial promotion and application.

[0106] Other structures of the hardware 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 herein.

[0107] The preferred embodiments disclosed above are only for the present invention, and of course cannot be used to limit the scope of rights of the present invention. 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.
