Description

Technical Field

[0001] This utility model relates to the field of household registration book technology, and in particular to a protective cover for household registration book. Background Technology

[0002] With social development and the improvement of people's living standards, the household registration booklet serves as an important identity certificate and carrier of household registration information. It records the basic information of family members, including names, genders, dates of birth, and marital status. It is an indispensable document for various social affairs such as school enrollment, marriage registration, property transactions, and household registration transfer. When enrolling children in school, schools need to check the household registration booklet to confirm the student's household registration information. When handling property transfer procedures, relevant departments will also verify the family relationship of the property owner based on the household registration booklet. Therefore, the completeness and clarity of information in the household registration booklet are of paramount importance.

[0003] Currently used paper household registration booklets mostly have covers made of ordinary paper with lamination and cardboard, while the inner pages are made of ordinary printing paper. During frequent use, they are prone to wear, folds, and tears. However, the soft materials used in current household registration booklets have relatively low hardness, making them more susceptible to scratches and wear when frequently in contact with and rubbed against objects during daily use. Over time, this can lead to surface damage, affecting the usability of the household registration booklet and reducing its efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a household registration booklet protective cover, which aims to improve the problem that the soft materials used in the current household registration booklets have relatively low hardness. In daily use, when frequently in contact and rubbing with other objects, scratches and wear are more likely to occur, leading to surface damage over time and affecting the usability of the household registration booklet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a household registration book protective cover, comprising a metal outer shell, wherein a rotating shaft is rotatably connected to the right side of the outer wall of the metal outer shell, and a rotating shaft is rotatably connected to adjacent rotating shafts, wherein a metal outer shell is rotatably connected to adjacent rotating shafts, and an arc-shaped frame is fixedly connected to the top of the metal outer shell and the metal outer shell near the edge, and a soft strip is fixedly connected to the left and right sides of the top of the metal outer shell and the metal outer shell.

[0006] As a further description of the above technical solution:

[0007] A locking groove is provided on one side of the flexible strip.

[0008] As a further description of the above technical solution:

[0009] The bottom of the second metal casing has a patch groove.

[0010] As a further description of the above technical solution:

[0011] The patch slot has an elongated design.

[0012] As a further description of the above technical solution:

[0013] The corners of the curved frame are curved.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by connecting and rotating the first metal shell and the second metal shell through the first and second rotating shafts, the first and second metal shells can be easily closed. Then, a patch groove is opened on the second metal shell. Finally, an arc frame is connected on the first and second metal shells to protect the outer wall of the protective sleeve, thereby increasing the drop resistance and surface strength. Thus, it can realize the diversified use of the household registration book. At the same time, the surface is a hard shell, which makes the household registration book less prone to damage and facilitates daily use by operators. Attached Figure Description

[0023] 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.

[0024] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model provides a household registration book protective cover, including a metal outer shell 1, a rotating shaft 2 rotatably connected to the right side of the outer wall of the metal outer shell 1, a rotating shaft 3 rotatably connected between adjacent rotating shafts 2, a metal outer shell 4 rotatably connected between adjacent outer walls of the multiple rotating shafts 2 3, an arc frame 8 fixedly connected to the top of the metal outer shell 1 and the metal outer shell 2 4 near the edge, and soft strips 5 fixedly connected to the left and right sides of the top of the metal outer shell 1 and the metal outer shell 2 4.

[0025] Specifically, multiple rotating shafts 2 are arranged at equal intervals on the right outer wall of the metal shell 1 via a precision hinge structure. The end of each rotating shaft 2 is engaged with the adjacent rotating shaft 3 to form a linkage mechanism. These rotating shafts 3 extend in the opposite direction and are connected to the corresponding positions of the metal shell 4 via universal joints to form a bidirectional folding transmission. At the top edge of the overall frame, the metal shell 1 and the metal shell 4 are fixed with a high-strength arc frame 8 and embedded snap-fit ​​silicone soft strips 5, which can achieve sealing protection in the folded state.
