Technical Field

[0001] The utility model relates to the field of short-beam padlocks, in particular to an outdoor short-beam padlock with an anti-prying function. Background Art

[0002] The padlock is a lock with a long history. It has a wide range of usage scenarios and is durable, being a common safety tool in daily life. A padlock usually consists of a lock body and a lock beam, and the lock body and the lock beam form a closed loop to achieve the locking effect.

[0003] The existing padlock is similar to a padlock disclosed in ZL202120366190.4. Through the control chip and coil in the lock body and the permanent magnet on the lock beam, it is possible to monitor the open or closed state of the padlock in real time during use. However, the lock beam of the existing such padlocks is exposed outside, and it is easy to be violently cut or pried off, resulting in the damage of the lock beam and the lock body, making the padlock lose its due protective effect.

[0004] Therefore, the existing anti-theft padlocks have the problem of poor anti-prying effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide an outdoor short-beam padlock with an anti-prying function.

[0006] The utility model has the advantage of better anti-prying effect.

[0007] The technical solution of the utility model: An outdoor short-beam padlock with an anti-prying function includes a lock body and a lock beam. The lock beam includes a long rod section and a short rod section. The lock body is provided with a long rod section hole and a short rod section hole corresponding to the long rod section and the short rod section, and a lock hole is arranged at the bottom of the lock body; a protective shell is connected to the periphery of the outside of the lock body, and an anti-prying shell is slidably connected in the protective shell; both sides of the top end of the anti-prying shell are connected with anti-prying plates located above the lock body, and strip-shaped lock beam openings are arranged at the positions corresponding to the lock beam on the two anti-prying plates; there is a gap between the two anti-prying plates, and U-shaped openings are arranged at both ends corresponding to the gap on the anti-prying shell; a horizontal slideway is arranged at the position corresponding to the short rod section in the lock body, and a spring buckle structure is arranged in the slideway; one end of the slideway communicates with the short rod section hole, and the other end of the slideway communicates with the anti-prying shell; a card hole matching with the spring buckle structure is arranged at the bottom inside the anti-prying shell.

[0008] In the aforementioned outdoor short-beam padlock with an anti-prying function, the spring buckle structure includes a dome clip and a triangular clip arranged at intervals, and a second spring is connected between the dome clip and the triangular clip; a third spring is connected between the end of the slideway close to the anti-prying shell and the triangular clip; the elastic coefficient of the second spring is greater than that of the third spring.

[0009] In the aforementioned outdoor short-beam padlock with an anti-prying function, first springs are connected between the bottoms of both sides of the anti-prying shell and the protection shell.

[0010] In the aforementioned outdoor short-beam padlock with an anti-prying function, handles are provided at the tops of both sides of the anti-prying shell, and one end of each handle protrudes horizontally outside the protection shell.

[0011] In the aforementioned outdoor short-beam padlock with an anti-prying function, two horizontal sliding rails are provided on both sides of the lock hole at the bottom of the lock body, and blocking bars are connected between the two ends of the two sliding rails; a dust-proof plate is slidably arranged between the two sliding rails.

[0012] Compared with the prior art, in the present utility model, due to the protection shell connected to the periphery of the outside of the lock body, external forces cannot directly act on the lock body, and it has a good anti-striking effect; through the anti-prying shell arranged between the lock body and the protection shell and the anti-prying plate at the upper end of the anti-prying shell, most of the lock beams are protected therein, making it difficult for tools such as crowbars and scissors to reach the lock beam for destructive operations, and it has a good anti-prying effect; through the long-strip-shaped lock beam openings provided at the positions corresponding to the lock beams on the two anti-prying plates, the anti-prying plates can be lifted around the lock beam more conveniently; through the intervals arranged between the two anti-prying plates and the U-shaped openings provided at the two ends corresponding to the intervals on the anti-prying shell, an activity space is left in the middle position of the lock beam, thus not affecting the normal locking of the padlock and improving the convenience of using the padlock; through the sliding grooves arranged at the positions corresponding to the short rod segments in the lock body, the spring snap structures arranged in the sliding grooves, and the card holes arranged at the positions corresponding to the sliding grooves at the inner bottom of the anti-prying shell, after the padlock is locked and the anti-prying shell is pulled up to the periphery of the lock beam, the anti-prying shell can be automatically fixed, which is more convenient to use.

[0013] In addition, by setting the dome clip, triangular clip, second spring and third spring, the spring snap structure can rely on the blocking effect of the lock beam on one end of the sliding groove and the elastic force of the second spring when the padlock is locked to realize the clamping connection between the triangular clip and the card hole, and when unlocking the padlock, it can rely on the elastic force of the third spring to make the triangular clip withdraw from the card hole and return to the sliding groove, realizing the automatic separation between the triangular clip and the card hole, which has good convenience.

[0014] Due to the first springs connected between the anti-prying shell and the protection shell, the anti-prying shell can be kept in a state of being retracted in the protection shell when not in use, thus making it more convenient to lock the padlock.

[0015] Due to the handles provided at the tops of both sides of the anti-prying shell, the user can pull the handles to lift the anti-prying shell more conveniently.

[0016] By means of the dust-proof plate arranged at the bottom of the lock body, the keyhole at the bottom of the padlock can avoid entering sundries such as dust and particles, which may affect the normal use of the padlock, and has a good dust-proof effect. By means of the slide rails horizontally arranged on both sides of the keyhole at the bottom of the lock body, the dust-proof plate can slide freely between the slide rails, so that the dust-proof plate can conveniently block or open the keyhole. By connecting blocking strips between both ends of the two slide rails, the dust-proof plate can slide stably between the two slide rails.

[0017] Therefore, the utility model not only can provide a good anti-prying effect, but also has the advantages of good anti-striking effect, good convenience and good dust-proof effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following further describes the present utility model in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the present utility model.

[0028] Embodiment. An outdoor short-beam padlock with anti-prying function is configured as follows Figures 1 to 8 as shown, including a lock body 1 and a lock beam 2. The lock beam 2 includes a long rod section 21 and a short rod section 22. The lock body 1 is provided with a long rod section hole 211 and a short rod section hole 221 corresponding to the long rod section 21 and the short rod section 22. A lock hole 3 is provided at the bottom of the lock body 1; a protective shell 4 is connected around the outside of the lock body 1, and an anti-prying shell 5 is slidably connected inside the protective shell 4; both sides of the top of the anti-prying shell 5 are connected with anti-prying plates 6 located above the lock body 1. Long strip-shaped lock beam openings 7 are provided at the positions corresponding to the lock beam 2 on the two anti-prying plates 6; there is a gap between the two anti-prying plates 6, and U-shaped openings 8 are provided at both ends corresponding to the gap on the anti-prying shell 5; a horizontal slideway 9 is provided inside the lock body 1 at the position corresponding to the short rod section 22, and a spring snap structure is arranged inside the slideway 9; one end of the slideway 9 communicates with the short rod section hole 221, and the other end of the slideway 9 communicates with the anti-prying shell 5; a card hole 11 that cooperates with the spring snap structure is provided at the bottom inside the anti-prying shell 5.

[0029] The spring snap structure includes a dome clip 101 and a triangular clip 102 arranged at intervals, and a second spring 103 is connected between the dome clip 101 and the triangular clip 102; a third spring 104 is connected between one end of the slideway 9 close to the anti-prying shell 5 and the triangular clip 102; the elastic coefficient of the second spring 103 is greater than that of the third spring 104.

[0030] First springs 12 are connected between the bottom of both sides of the anti-prying shell 5 and the protective shell 4.

[0031] Pull handles 13 are provided at the top of both sides of the anti-prying shell 5, and one end of the pull handle 13 protrudes horizontally outside the protective shell 4.

[0032] Two horizontal slide rails 14 are provided on both sides of the lock hole 3 at the bottom of the lock body 1, and blocking strips 15 are connected between the two ends of the two slide rails 14; a dust-proof plate 16 is slidably arranged between the two slide rails 14.

[0033] Working principle: When the user needs to lock the padlock, first rotate the long rod section 21 connected in the long rod section hole 211 to stagger the short rod section 22 from the lock body 1, and then pass the short rod section 22 through the door nose; then, rotate the long rod section 21 back to align the short rod section 22 with the short rod section hole 221, and then press the lock beam 2 to insert the short rod section 22 into the short rod section hole 221 to complete locking.

[0034] After locking is completed, pull the handle 13 to raise the anti-pry shell 5 from between the lock body 1 and the protective shell 4; at this time, the lock beam 2 will pass through the long strip-shaped lock beam opening 7 in the middle of the proximal ends of the two anti-pry plates 6, and the locking position will also pass through the opening 8 in the middle of the wide sides of both sides of the anti-pry shell 5, so that the anti-pry shell 5 and the anti-pry plates 6 can be smoothly raised, improving the convenience of use; when the anti-pry shell 5 is raised to the top, since the short rod section 22 of the lock beam 2 squeezes the dome clip 101 of the spring snap structure into the slideway 9, the second spring 103 and the third spring 104 are squeezed and compressed; and the elastic coefficient of the second spring 103 is greater than that of the third spring 104, so that the third spring 104 is compressed first, so that the triangular clip 102 will pop out of the slideway 9 and snap into the card hole 11 provided on the anti-pry shell 5, so that the anti-pry shell 5 and the anti-pry plates 6 stably surround the lock beam 2, playing a better anti-pry effect on the lock beam 2; slide the dust-proof plate 16 along the slide rail 14 to the blocking strip 15 close to the lock hole 3 to shield the lock hole 3, preventing foreign matters such as dust from entering the lock body 1 from the lock hole 3, playing a better dust-proof effect.

[0035] When unlocking the padlock, slide the dust-proof plate 16 between the two slide rails 14 at the bottom of the lock body 1 to the blocking strip 15 away from the lock hole 3 to expose the lock hole 3, and then use the key to unlock the padlock; after the lock beam 2 is separated from the lock body 1, since the short rod section 22 of the lock beam 2 withdraws from the short rod section hole 221, the dome clip 101 will not be blocked by the short rod section 22, and the second spring 103 with a larger elastic coefficient will first recover from the compressed state and pop the dome clip 101 out of the slideway 9; at this time, since the second spring 103 no longer generates elastic force after restoring its shape, under the elastic force of the compressed third spring 104, the triangular clip 102 is withdrawn from the card hole 11 and retracted into the slideway 9; after the triangular clip 102 in the card hole 11 is withdrawn, the anti-pry shell 5 will be retracted into the protective shell 4 under the elastic force of the stretched first spring 12, so that the lock beam 2 is exposed again, and the padlock can be removed more conveniently.
