[0001] This utility model relates to the field of lock technology, specifically to a padlock with anti-pry reinforcement components. Background Technology
[0002] Locks are common items in people's daily lives, and there are many different types. Padlocks are a relatively common type of lock. However, commonly used padlocks are prone to shaking and impacts during use, which can damage doors, other items using the padlock, and the padlock itself. Existing padlocks also have disadvantages such as low tensile strength, easy deformation, and the lock shank easily breaking during prying, resulting in poor anti-theft performance.
[0003] Chinese utility model patent CN 211038203 U discloses a padlock, including a lock body and a protective sleeve disposed on the lock body. The protective sleeve includes a bottom surface with an opening and a side wall integrally formed with the bottom surface. The bottom surface and the side wall form a groove corresponding to the lock body, into which the lock body is installed. This utility model of a padlock can effectively reduce damage caused by impacts to the padlock and provides protection for the padlock, doors, or other items using the padlock.
[0004] The aforementioned publicly available documents still have some problems in use. They do not have components to prevent lock picking, so the lock body can still be damaged by lock picking, resulting in poor anti-theft performance. Therefore, there is a need for a padlock with anti-pry reinforcement components. Utility Model Content
[0005] The purpose of this utility model is to provide a padlock with anti-pry reinforcement components. By setting two sets of rotatable L-shaped rotating plates to limit the padlock beam, the space between the padlock body and the padlock beam is sealed to avoid damage from prying, thereby solving the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a padlock with anti-pry reinforcement components, comprising a padlock body and a padlock beam used in conjunction with the padlock body, and an anti-pry component rotatably mounted on the upper part of the padlock body for reinforcing the padlock beam;

[0011] Preferably, two sets of positioning shafts are installed opposite each other on the left and right sides of the upper surface of the padlock body. Each set of positioning shafts has several sets of reinforcing sleeves on its outer surface. A set of first positioning holes is opened on one side of each set of positioning shafts on the upper surface of the padlock body.
[0012] Preferably, a set of support springs is installed inside each set of first positioning holes, and a set of limiting plates is slidably installed inside the first positioning holes. The limiting plates are placed on the top of the support springs, and the diameter of the opening at the top of the first positioning hole is smaller than that of the limiting plates. A plug rod is fixedly installed at the top of the limiting plates, and the plug rod extends elastically from the opening at the top of the first positioning hole.
[0013] Preferably, each of the L-shaped rotating plates has a second positioning hole through the corresponding positioning shaft position, the positioning shaft is inserted into the second positioning hole, and both the positioning shaft and the outer arc surface of the reinforcing sleeve are in contact with the inner wall of the second positioning hole.
[0014] Preferably, each set of L-shaped rotating plates has a through hole corresponding to the same side of the insertion rod position, the insertion rod is elastically inserted into the insertion hole, and a set of plugs is sealed and inserted into the insertion hole of each set.
[0015] Preferably, the L-shaped rotating plate has a raised reinforcing block on one side of the surface corresponding to the bonding plate position.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1-5 As shown, a padlock with anti-pry reinforcement components includes a padlock body 1 and a padlock beam 3 used in conjunction with the padlock body 1, as well as an anti-pry component rotatably mounted on the upper part of the padlock body 1 for reinforcing the padlock beam 3.
[0027] The center of the padlock beam 3 is a carbon steel beam core 4. The bending position of the padlock beam 3 is located outside the carbon steel beam core 4 and is fitted with a nickel alloy reinforcing beam wall 5. The carbon steel beam core 4 and the nickel alloy reinforcing beam wall 5 in the center of the padlock beam 3 can provide strong support for the entire padlock and prevent the lock body from deforming when pried. At the same time, the nickel alloy reinforcing beam wall 5 can enhance the shear resistance of the entire padlock beam 3 and greatly improve the safety of the padlock beam 3.
[0028] The anti-pry assembly includes two sets of L-shaped rotating plates 12 that are rotatably mounted relative to each other. Each set of L-shaped rotating plates 12 has a set of bonding plates 15 installed on the corresponding side. Each set of bonding plates 15 has an arc-shaped groove 18 on the upper part of the bonding side corresponding to the nickel alloy reinforcing beam wall 5. Each set of bonding plates 15 has a locking groove 20 in the middle of the arc-shaped groove 18. The L-shaped rotating plates 12 can be rotated and closed. The arc-shaped groove 18 is used to support the padlock beam 3. In addition, the locking groove 20 in the middle of the arc-shaped groove 18 can ensure the normal use of the padlock.
[0029] After the padlock beam 3 is pressed down, it fits against the inner wall of the two sets of arc grooves 18. The pressing down of the padlock beam 3 fits against the arc grooves 18, which compresses the space between the padlock beam 3 and the padlock body 1, thus preventing the lever from being inserted into the lock body to pry it open.
[0030] Furthermore, a set of reinforcing seats 2 are installed on the upper surface of the padlock body 1 at the two ends of the padlock beam 3. After the lock head of the padlock beam 3 is inserted into the padlock body 1, the surface of the padlock beam 3 is installed against the inner wall of the reinforcing seat 2. The reinforcing seats 2 are set to limit the two ends of the connection between the padlock beam 3 and the padlock body 1, thereby improving the protection of the padlock beam 3.
[0031] Furthermore, two sets of positioning shafts 6 are installed opposite each other on the left and right sides of the upper surface of the padlock body 1. Several sets of reinforcing sleeves 7 are provided on the outer surface of each set of positioning shafts 6. A set of first positioning holes 8 is opened on one side of the upper surface of the padlock body 1 corresponding to each set of positioning shafts 6. The positioning shafts 6 and reinforcing sleeves 7 cooperate with the L-shaped rotating plate 12 to ensure the rotation of the L-shaped rotating plate 12 and determine the overall rotation angle and position of the L-shaped rotating plate 12, so that the two sets of L-shaped rotating plates 12 can close to support the padlock beam 3.
[0032] Furthermore, a set of support springs 9 are installed inside each set of first positioning holes 8, and a set of limiting plates 10 are slidably installed inside the first positioning holes 8. The limiting plates 10 are placed on the top of the support springs 9, and the opening diameter of the top of the first positioning hole 8 is smaller than that of the limiting plates 10. A plug rod 11 is fixedly installed on the top of the limiting plates 10. The plug rod 11 extends elastically from the opening at the top of the first positioning hole 8. The first positioning hole 8 limits the support springs 9, and the support springs 9 can apply an upward force to the limiting plates 10 and the plug rod 11, so that the plug rod 11 is inserted into the insertion hole 14 to complete the auxiliary positioning of the L-shaped rotating plate 12.
[0033] Furthermore, each set of L-shaped rotating plates 12 has a second positioning hole 13 through which the positioning shaft 6 is located. The positioning shaft 6 is inserted into the second positioning hole 13, and the outer arc surfaces of the positioning shaft 6 and the reinforcing sleeve 7 are both in contact with the inner wall of the second positioning hole 13. The reinforcing sleeve 7 is installed on the outside of the positioning shaft 6 to strengthen the strength of the positioning shaft 6 and prevent the L-shaped rotating plate 12 from bending and being damaged during use.
[0034] Furthermore, each set of L-shaped rotating plates 12 has a through hole 14 corresponding to the position of the same side insertion rod 11. The insertion rod 11 is elastically inserted into the insertion hole 14, and a set of plugs 19 is sealed inside each set of insertion holes 14. The insertion rod 11 is elastically inserted into the insertion hole 14 through the support spring 9, which helps to determine the position of the two sets of L-shaped rotating plates 12, thus reducing the difficulty for the user to lock the L-shaped rotating plates 12.
[0035] Furthermore, the L-shaped rotating plate 12 has a raised reinforcing block on one side of the surface corresponding to the position of the bonding plate 15. One set of bonding plates 15 has a connecting lock hole 16, and the other set of bonding plates 15 has a lock cylinder 17 installed in the corresponding connecting lock hole 16. The lock cylinder 17 rotates and engages with the connecting lock hole 16. The user can control the padlock and the lock cylinder 17 with a key. After the two sets of bonding plates 15 are properly bonded, the lock cylinder 17 is rotated to lock the positions of the two sets of bonding plates 15, further improving the strength of the two sets of bonding plates 15 and reducing the possibility of prying and damaging the lock body.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
