In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0032] Example 1: See Figure 1 , Figure 2 and Figure 3A wrapped lock core structure includes a lock shell 1 and a lock core 2 arranged in the lock shell 1, and a dial mechanism 3 is arranged on the lock core 2. The lock shell 1 includes a first lock core wrapping body 11 and a second lock core wrapping body 12. The first lock core wrapping body 11 and the second lock core wrapping body 12 are connected as a whole through a connecting body 13, and the connecting body 13 is covered with an outer shell 14. When the outer shell 14 is covered on the connecting body 13, both ends of the outer shell 14 are consistent with the corresponding outer end faces of the first lock core wrapping body 11 and the second lock core wrapping body 12.

[0033] The outer shell 14 of the utility model is covered on the connecting body 13, and the production, manufacturing and installation are simple, which reduces the difficulty of production, manufacturing and installation. The two ends of the outer shell 14 are consistent with the outer end faces of the corresponding first lock core enclosure 11 and the second lock core enclosure 12. The whole is more novel and beautiful. There is no protruding effect at the two ends of the lock shell 1, which is more conducive to meeting the use requirements.

[0034] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first lock core enclosure 11, the second lock core enclosure 12 and the connector 13 are all integrally formed of iron or stainless steel materials, which greatly improves the firmness of the structure, and the outer shell 14 is made of plastic or aluminum or zinc alloy, ending the prior art in which the lock shell 1 is entirely made of copper materials. Since copper materials are relatively expensive, a lot of costs can be saved and the production needs of manufacturers can be better met.

[0035] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Figure 1 As shown, the upper end surface of the first lock core enclosure 11 and an outer end surface of the connecting body 13 form a first space 15, and the upper end surface of the second lock core enclosure 12 and the other end surface of the connecting body 13 form a second space 16. This arrangement is more conducive to the outer shell 14 being wrapped around the connecting body 13, and the end surfaces on both sides of the outer shell 14 are consistent with the corresponding outer end surfaces of the first lock core enclosure 11 and the second lock core enclosure 12. This arrangement is more conducive to meeting usage requirements.

[0036] like Figure 5As shown, it is further explained that the shell 14 includes a shell 141 and a first end cover 142 and a second end cover 143 arranged on the end surface of the shell 141, the shell 141 and the first end cover 142 and the second end cover 143 are integrally formed, and an installation cavity 144 is formed between the first end cover 142, the second end cover 143 and the shell 141, and the length of the installation cavity 144 is exactly equal to the length of the connecting body 13, which is conducive to wrapping the connecting body 13, and the first end cover 142 is just located on the first space 15, and the second end cover 143 is just located on the second space 16. This arrangement is conducive to the two ends of the shell 14 being consistent with the outer end surfaces of the corresponding first lock core enclosure 11 and the second lock core enclosure 12, and will not protrude, which can meet actual needs.

[0037] like Figure 1 As shown, it is further explained that an anti-collision sheet 17 is installed on the first space 15 and / or the second space 16. The anti-collision sheet 17 can prevent the housing 14 from hitting the two ends of the connector 13 during installation, especially the connector 13 made of copper. At the same time, it will also make the housing 14 and the connector 13 more tightly installed, which is more conducive to meeting the use requirements. Specifically, an anti-collision (drilling) sheet 17 can be installed on the first space 15 or the second space 16, or an anti-collision sheet 17 can be installed on both the first space 15 and the second space 16. In this way, the anti-collision sheet 17 can be installed as needed. It is particularly emphasized that the anti-collision sheet 17 is made of iron sheet, which has a better anti-drilling effect.

[0038] Embodiment 4: It can be described on the basis of Embodiment 1, Embodiment 2 or Embodiment 3, such as Figure 2 , Figure 3 and Figure 4 As shown, the shell 14 is locked by the connecting pin 18 when it is wrapped around the connecting body 13 , which can prevent collision when a drill is used, thereby increasing the service life and also facilitating the fixing of the shell 14 on the connecting body 13 .

[0039] Embodiment 5: It can be described on the basis of Embodiment 1, Embodiment 2 or Embodiment 3, such as Figure 6 As shown, at least one clamping hole 19 is provided on the connecting body 13, and correspondingly, a protrusion is provided on the inner wall of the outer shell 14, and the protrusion is inserted into the clamping hole 19 so that the outer shell 14 is fixedly clamped on the connecting body 13 to prevent it from being easily removed. In this embodiment, there are two clamping holes 19 and two protrusions, and each protrusion is correspondingly inserted into the corresponding clamping hole 19, so that the outer shell 14 is fixedly clamped on the connecting body 13 more stably and more practically.

[0040] As for installing a square shaft on the lock core, this is a technology well known to those skilled in the art and will not be described in detail here.

[0041] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature lock cores, square shafts and dial wheel mechanisms in the prior art, and no specific description will be given here.

[0042] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
