Description

Technical Field

[0001] This utility model relates to a desk calendar, and more specifically, to a fixing ring for a desk calendar. Background Technology

[0002] Traditional desk calendars use numerous fixing rings to connect the front and back support plates and the calendar pages. Existing fixing rings typically include two arc-shaped rings. One end of each arc-shaped ring is hinged to a pivot for rotational connection, while the other end has a pivot on one arc-shaped ring and a locking block on the other arc-shaped ring that engages with the pivot. This installation method requires two pivots, making installation inconvenient, time-consuming, and labor-intensive. Furthermore, using two pivots increases production costs, necessitating an improvement. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fixing ring for a desk calendar, which can be quickly installed using only one pivot, saving time and effort during installation and greatly reducing production costs.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fixing ring for a desk calendar, comprising a left ring body and a right ring body that interlock to form a circular ring. One end of the left ring body and the right ring body are hinged and fixed by a pivot. An installation groove is provided at the end of the left ring body, and a locking post integrally formed with the left ring body is provided in the installation groove. An integrally formed locking block is provided at the end of the right ring body. The locking block is adapted to the installation groove, and the outer side of the locking block is provided with a locking groove adapted to the locking post.

[0005] The present invention is further configured such that the locking post is located in the mounting groove near the outer side of the left ring body.

[0006] The present invention is further configured such that: the upper and lower sides of the card block are respectively provided with protrusions that abut against the inner walls of the upper and lower sides of the mounting groove.

[0007] The present invention is further configured such that: at least two protrusions are provided and distributed on both sides of the slot.

[0008] The present invention is further configured such that: the end of the card block near the outer side of the right ring body is provided with a first arc-shaped chamfer, and the side of the card post near the inner side of the left ring body is provided with a second arc-shaped chamfer.

[0009] By adopting the above technical solution, the fixed ring of this utility model can be quickly installed using only one shaft, which saves time and effort during installation and can greatly reduce production costs and improve the competitiveness of enterprises. Attached Figure Description

[0012] Reference Figures 1 to 3 The embodiments of this utility model will be further described below.

[0013] This utility model discloses a fixing ring for a desk calendar, including a left ring body 1 and a right ring body 2 that interlock to form a circular ring. One end of the left ring body 1 and the right ring body 2 are hinged and fixed by a pivot. The end of the left ring body 1 is provided with a mounting groove 10, and a locking post 11 integrally formed with the left ring body 1 is provided in the mounting groove 10. The end of the right ring body 2 is provided with an integrally formed locking block 20. The locking block 20 is adapted to the mounting groove 10, and the outer side of the locking block 20 is provided with a locking groove 21 adapted to the locking post 11.

[0014] Furthermore, the locking post 11 is located in the mounting groove 10 near the outer side of the left ring body 1. By positioning the locking post 11 near the outer side of the left ring body 1, when fastening the left ring body 1 and the right ring body 2, it is only necessary to gently press the end of the right ring body 2 to fasten and install them, making the operation easier.

[0015] Furthermore, the upper and lower sides of the locking block 20 are respectively provided with protrusions 22 that abut against the inner walls of the upper and lower sides of the mounting groove 10. By providing protrusions 22 on the upper and lower sides of the locking block 20, the left ring body 1 and the right ring body 2 can be pressed and fixed by the protrusions 22 when they are engaged, which improves the stability between the left ring body 1 and the right ring body 2 and makes it less prone to shaking.

[0016] Furthermore, at least two protrusions 22 are provided and distributed on both sides of the slot 21. By providing at least two protrusions 22 and distributing them on both sides of the slot 21, the stability between the left ring body 1 and the right ring body 2 is improved, and it is less prone to vertical wobbling.

[0017] Furthermore, the locking block 20 has a first arc-shaped chamfer 23 at the end near the outer side of the right ring body 2, and the locking post 11 has a second arc-shaped chamfer 12 on the side near the inner side of the left ring body 1. By providing the first arc-shaped chamfer 23 on the locking block 20 and the second arc-shaped chamfer 12 on the locking post 11, the left ring body 1 and the right ring body 2 can be more smoothly engaged and installed during installation, making the installation more convenient.

[0018] Working principle: When installing the fixing ring of this utility model, simply hinge one end of the left ring body 1 and the right ring body 2 together using a pivot. Then, hold the left ring body 1 and the right ring body 2 and fasten them together. During fastening, apply force to press the end of the right ring body 2 inward, causing the locking block 20 at the end of the right ring body 2 to displace and slide into the mounting groove 10, thus displacing the locking post 11. When the locking block 20 slides into the mounting groove 10, release the force applied to the right ring body 2. At this time, the right ring body 2 will drive the locking block 20 to reset, thereby causing the locking post 11 to be locked in the locking groove 21 on the outer side of the locking block 20, thus achieving quick and convenient installation of the fixing ring. By setting the locking post 11 to be integrally formed with the left ring body 1, the installation steps of the rotating shaft can be reduced. The integral forming process of the locking post 11 and the left ring body 1, and the locking block 20 and the right ring body 2 can be selected according to the material. For example, when plastic material is used, plastic mold injection molding can be used, and when metal material is used, casting process can be used. The selection can be made according to customer needs.

[0019] This practical retaining ring requires only one pivot for quick installation, saving time and effort while significantly reducing production costs and enhancing a company's competitiveness.

[0020] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
