Description

Technical Field

[0001] The utility model relates to the field of padlocks, in particular to a rainproof and dustproof outdoor padlock. Background Art

[0002] As the oldest member of the family of locks, the padlock has a simple structure, low production cost, and is durable. It is an indispensable safety tool in daily life.

[0003] The existing padlock is similar to a padlock disclosed in ZL202221976677.5. Its lock core is directly connected to the lock body through the installation hole, which reduces the number of assembled parts and thus lowers the production cost. However, as a safety tool often used outdoors, the padlock is often exposed to wind, rain, and dust. There are multiple gaps on the lock body of this type of padlock, and the lock core at the bottom of the lock body is exposed. Rainwater, dust, etc. can easily enter the interior of the lock body, resulting in the padlock being rusted or unable to be used normally due to foreign objects entering.

[0004] Therefore, the existing padlock has the problem of poor rainproof and dustproof effects. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rainproof and dustproof outdoor padlock. The utility model has the advantage of better rainproof and dustproof effects.

[0006] The technical solution of the utility model: A rainproof and dustproof outdoor padlock includes a lock body and a lock beam. A lock hole is provided at the bottom of the lock body, and a spring is connected between the lock body and the lock beam; an elastic waterproof layer is connected to the top of the lock body, and two circular holes are provided on the elastic waterproof layer corresponding to the position of the lock beam. The diameters of the two holes are both 1 mm smaller than the diameter of the lock beam; a groove is provided at the bottom of the lock body corresponding to the position of the lock hole, and horizontally arranged L-shaped sliding rails are connected to both sides above and below the lock hole in the groove; blocking blocks are connected to both ends of the two sliding rails, and an inwardly protruding elastic piece is arranged in the middle of the inner sides of the two sliding rails; a dustproof cover is slidably connected between the two sliding rails, and the four corners of the dustproof cover are all arc-shaped.

[0007] In the above-mentioned rainproof and dustproof outdoor padlock, a plurality of fixing holes are provided on the top of the lock body; fixing protrusions are arranged at the bottom of the elastic waterproof layer corresponding to the positions of each fixing hole.

[0008] In the above-mentioned rainproof and dustproof outdoor padlock, the elastic waterproof layer is made of TPU material.

[0009] In the above-mentioned rainproof and dustproof outdoor padlock, the position of the lock body corresponding to the lock beam in the middle of the top surface of the lock body is higher than the edge position of the top surface of the lock body.

[0010] In the above-mentioned rainproof and dustproof outdoor padlock, the outer side surface of the dustproof cover is provided with anti-slip corrugations.

[0011] Compared with the prior art, in the present utility model, two holes with diameters smaller than the diameter of the lock beam are opened on the elastic waterproof layer at the top of the lock body, so that after the padlock is locked, the elastic waterproof layer can hermetically surround the lock beam, blocking the gap between the lock beam and the lock body, preventing rainwater, dust, etc. from flowing into the interior of the lock body, thereby enabling the lock body to have a better rain and dust prevention effect; by providing a dust-proof cover at the bottom of the lock body, foreign matters such as rainwater and dust are blocked outside the dust-proof cover and cannot reach the lock hole, improving the rain and dust prevention effect; by horizontally arranging two slide rails around the lock hole and providing blocking blocks at both ends of the slide rails, the dust-proof cover can slide within the slide rails, and it is more convenient to block and open the lock hole; by providing an inwardly protruding elastic piece in the middle of the inner side of the slide rail, the dust-proof cover is positioned, enabling the dust-proof cover to stably cover the lock hole below the lock hole or stably open the lock hole at the side below the lock hole, which is more convenient to use; by providing a groove at the bottom of the lock body corresponding to the position of the lock hole, the slide rails and the dust-proof cover can be arranged in the groove, and when the padlock is placed or the bottom of the lock body is bumped, the slide rails and the dust-proof cover will not be touched, causing wear to the slide rails and the dust-proof cover, thereby enabling the slide rails and the dust-proof cover to have better durability; by setting the four corners of the dust-proof cover to be arc-shaped, when the dust-proof cover slides past the position of the elastic piece on the inner side of the slide rail, the force exerted by the dust-proof cover on the elastic piece makes it easier for the elastic piece to be squeezed and deformed, so that the dust-proof cover can more conveniently slide past the position of the elastic piece.

[0012] In addition, through a plurality of fixing holes provided at the top of the lock body and a plurality of fixing protrusions provided at the bottom of the elastic waterproof layer, the elastic waterproof layer can be more conveniently connected to the top of the lock body by embedding the fixing protrusions into the fixing holes.

[0013] Since the TPU material has good wear resistance, temperature resistance and anti-aging properties, the elastic waterproof layer made of the TPU material has good durability.

[0014] Since the position corresponding to the lock beam in the middle of the top surface of the lock body is higher than the edge position of the top surface of the lock body, the rainwater on the top of the lock body can flow down along the inclined surface and will not accumulate on the top of the lock body, improving the rain prevention effect.

[0015] By providing anti-slip corrugations on the outer side surface of the dust-proof cover, when pushing the dust-proof cover to slide, there can be a greater frictional force, so that the sliding of the dust-proof cover is more convenient.

[0016] Therefore, the present utility model can not only better prevent rain and dust, but also has the advantages of better convenience and better durability. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present utility model will be further described below with reference to the drawings and embodiments, but it shall not be used as a basis for limiting the present utility model.

[0026] Embodiment. A rain - proof and dust - proof outdoor padlock, the structure of which is as Figures 1 to 7 shown, including a lock body 1 and a lock beam 2. A lock hole 6 is provided at the bottom of the lock body 1, and a spring 3 is connected between the lock body 1 and the lock beam 2; a top of the lock body 1 is connected with an elastic waterproof layer 4. At a position corresponding to the lock beam 2 on the elastic waterproof layer 4, there are two circular holes 5, and the diameters of both holes 5 are 1 mm smaller than the diameter of the lock beam 2; at a position corresponding to the lock hole 6 at the bottom of the lock body 1, there is a groove 7, and horizontally arranged L - shaped slide rails 8 are connected to both the upper and lower sides of the lock hole 6 in the groove 7; both ends of the two slide rails 8 are connected with blocking blocks 9, and an inward - protruding elastic sheet 10 is arranged in the middle of the inner sides of the two slide rails 8; a dust cover 11 is slidably connected between the two slide rails 8, and the four corners of the dust cover 11 are all arc - shaped.

[0027] A plurality of fixing holes 12 are provided on the top of the lock body 1; at a position corresponding to each fixing hole 12 at the bottom of the elastic waterproof layer 4, there is a fixing protrusion 13.

[0028] The elastic waterproof layer is made of TPU material.

[0029] The middle part of the top surface of the lock body 1 corresponding to the lock beam 2 is higher than the edge position of the top surface of the lock body 1.

[0030] The outer side surface of the dust cover 11 is provided with anti - slip corrugations.

[0031] Working principle: When the door needs to be locked, put the lock beam 2 through the door nose, then press down the lock beam 2 against the lock beam hole until the lock beam 2 moves down to the bottom of the lock beam hole and then release the hand; at this time, the spring 3 connected between the lock body 1 and the lock beam 2 will generate elastic force due to being compressed and push the lock beam 2 to move upward; when the lock beam 2 moves upward due to the elastic force of the spring 3, since the diameter of the hole 5 is 1 mm smaller than the diameter of the lock beam 2, there will be a large frictional force between the lock beam 2 and the elastic waterproof layer 4 at the position of the hole 5, so that the lock beam 2 can drive the elastic waterproof layer 4 at the hole 5 to move upward together; after the lock beam 2 stops moving upward, the elastic waterproof layer 4 at the hole 5 will closely adhere to the periphery of the lock beam 2 and be in a convex state, preventing rainwater from accumulating around the lock beam 2 and seeping into the gap between the lock body 1 and the lock beam 2, having a good waterproof effect.

[0032] After locking is completed, slide the dust cover 11 in the slide rail 8 so that it can more conveniently squeeze the elastic piece 10 bulging inward at the middle of the inner side of the slide rail 8 through the four arc-shaped corners; after the elastic piece 10 is squeezed and deformed, the space at this section of the slide rail 8 will become larger, enabling the dust cover 11 to reach the position below the lock hole 6 through the elastic piece 10; at this time, the elastic piece 10 returns to the state of bulging inward due to the elastic force recovery, making the dust cover 11 stably located below the lock hole 6 to block the lock hole 6, playing a good rain and dust prevention effect.

[0033] When unlocking, slide the dust cover 11 in the slide rail 8 so that it passes through the elastic piece 10 from the position below the lock hole 6 to the side position of the lock hole 6 to open the lock hole 6; then insert the key into the lock hole 7 to perform the unlocking operation.

[0034] When the elastic waterproof layer 4 needs to be replaced, just pinch the edge of the elastic waterproof layer 4 and pull it forcefully so that the multiple fixing protrusions 13 are all separated from the multiple corresponding fixing holes 12 at the top of the lock body 1, and then pull the elastic waterproof layer 4 along the lock beam 2 to make it separate from the lock beam 2 and remove it; then, pick up the new elastic waterproof layer 4, determine the front and back sides, align one hole 5 with the end of the lock beam 2 and put it on; then, pull the elastic waterproof layer 4 to move along the lock beam 2 until the elastic waterproof layer 4 fits to the top of the lock body 1; finally, embed the multiple fixing protrusions 8 at the bottom of the elastic waterproof layer 4 into the corresponding fixing holes 7 at the top of the lock body 1.
