DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] See also Figure 1-Figure 4 The utility model provides the following technical solutions: a semi-wrapped beam padlock with a serpentine lock core that prevents misinsertion, comprising a lock body 1, a lock beam 2 arranged at the top of the lock body 1, and a serpentine groove lock core 3 arranged on the inner side of the bottom end of the lock body 1, a plug hole 11 for the free end of the lock beam 2 to pass through is opened on the lock body 1, and also includes a protective mechanism 4, two groups of protective mechanisms 4 are symmetrically arranged at the position of the bottom surface of the lock body 1 corresponding to the serpentine groove lock core 3, and the protective mechanism 4 includes: a protective block 41 and an elastic component.
[0031] Further, by Figure 1 and Figure 2 As shown, in the present embodiment, a guide groove 411 is opened on the protection block 41 along the inclined direction, and the protection block 41 is connected to the lock body 1 by means of an elastic component, and when the two protection blocks 41 move away from the outside, the elastic component elastically contracts. Therefore, when the half-beam padlock is in use or idle, the two protection blocks 41 can be moved closer to the inside and docked together through the action of the elastic component. The two protection blocks 41 protect the serpentine groove lock core 3 to prevent foreign objects from being mistakenly inserted into the keyhole of the serpentine groove lock core 3, thereby improving the safety of use. The protection mechanism 4 also has a guiding function. Through the guide groove 411 extending in the inclined direction, the key can be accurately inserted into the keyhole of the serpentine groove lock core 3 even in a dark environment, which is more convenient to use.
[0032] Optionally, by Figure 1 and Figure 2As shown, in this embodiment, the elastic component includes: a fixed bracket 42 and a reset spring 44. The fixed bracket 42 is fixed on the bottom surface of the lock body 1, and the reset spring 44 is fixed between the protective block 41 and the fixed bracket 42. After the key is inserted into the guide groove 411, the key is pushed. The key squeezes the inclined surface of the guide groove 411, which will generate a component force to push the protective block 41 toward the outside. The two protective blocks 41 move away from the outside, and the reset spring 44 contracts. After the key is pulled out, the reset spring 44 releases the elastic force, and the two protective blocks 41 move toward the inside and dock together.
[0033] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, it also includes: a mounting rod 43, the mounting rod 43 is fixed on the protective block 41 and passes through the fixed bracket 42, the return spring 44 is sleeved on the mounting rod 43, and the mounting rod 43 cooperates with the fixed bracket 42 to stably install the protective block 41, and at the same time guides the protective block 41 so that the protective block 41 can only be displaced along a straight line.
[0034] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, two symmetrically distributed mounting rods 43 are fixed on the same protection block 41 to ensure the stability of the protection block 41 and prevent the protection block 41 from accidentally rotating.
[0035] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, a limit plate 45 is fixed on the protruding end of the mounting rod 43 to limit the moving range of the protection block 41 .
[0036] Preferably, by Figure 1 and Figure 2 As shown, in the present embodiment, a conical groove 412 is provided on the protective block 41, and the guide groove 411 is located in the conical groove 412, so as to further improve the convenience of inserting the key. In a dark environment, since the lower part of the conical groove 412 is larger, the key can be easily pushed into the conical groove 412, and the key can be appropriately rotated at a certain angle until the key is rotated into the guide groove 411. The key can be pushed to accurately insert the key into the keyhole of the serpentine groove lock cylinder 3 under the guidance of the guide groove 411.
[0037] Preferably, by Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, it also includes: a rubber sealing gasket 5, which is fixed in the socket 11 and has a through hole 51 at the center of the rubber sealing gasket 5. The rubber sealing gasket 5 is flexible, so the diameter of the through hole 51 does not need to be too large. When the free end of the lock beam 2 passes through the through hole 51, the through hole 51 can automatically expand. When idle, the rubber sealing gasket 5 can prevent external dust from falling into the socket 11 to a certain extent.
[0038] Preferably, by Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the top surface of the rubber sealing gasket 5 is a spherical surface protruding upward, and the bottom surface is an inclined surface inclined upward, so that dust and water stains will not accumulate on the top surface of the rubber sealing gasket 5, and it is also easy to clean. At the same time, the structure of the rubber sealing gasket 5 also facilitates the free end of the lock beam 2 to pass through the through hole 51. The through hole 51 not only expands automatically, but also can bend downward to ensure that the free end of the lock beam 2 can reliably pass through the through hole 51.
[0039] Components not described in detail herein are prior art.
[0040] Working principle and use process of the utility model: the serpentine lock core semi-wrapped beam padlock of the utility model, when the semi-wrapped beam padlock is in use or idle, the two protection blocks 41 approach and dock together toward the inside under the elastic force of the reset spring 44, and protect the serpentine groove lock core 3, so as to prevent foreign objects from being mistakenly inserted into the keyhole of the serpentine groove lock core 3, thereby improving the safety of use;
[0041] Under the action of the tapered groove 412 and the guide groove 411, in a dark environment, since the lower part of the tapered groove 412 is larger, the key can be easily pushed into the tapered groove 412, and the key can be properly rotated at a certain angle until the key is rotated into the guide groove 411. The key can be pushed and accurately inserted into the keyhole of the serpentine groove lock cylinder 3 under the guidance of the guide groove 411. Even in a dark environment, the key can be accurately inserted into the keyhole of the serpentine groove lock cylinder 3, which is more convenient to use;
[0042] After the key is inserted into the guide groove 411, the key is pushed. The key squeezes the inclined surface of the guide groove 411, which generates a component force to push the protective block 41 toward the outside. The two protective blocks 41 move away from each other, and the reset spring 44 contracts. After the key is pulled out, the reset spring 44 releases the elastic force, and the two protective blocks 41 move toward the inside and dock together.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
