Text binding coil

Abstract

This utility model discloses a text binding coil, relating to the field of stationery. The key technical features are: a coil body composed of several spiral rings of equal diameter; a collar at one end of the coil body; a circular ring movably connected to the collar; a limiting rod on the circular ring; and a deformable part on the limiting rod. After all the spiral rings pass through the holes in the text, the deformable part restricts one end of the limiting rod to the coil body. At this time, the other end of the limiting rod is restricted by the collar, thus restricting both ends of the limiting rod. Consequently, when the coil body is subjected to external force and tends to rotate, the limiting rod will come into contact with the text, thus restraining the coil body to the text. Compared to existing technologies, this binding coil's method of restraining the text is more convenient. The coil body, made of PVC material, can withstand long-term friction with text, improving the coil body's service life.

Description

Technical Field

[0001] This utility model relates to the field of stationery, and more specifically, to text binding coils. Background Technology

[0002] Text binding coils are a common material used to secure text. After the text is punched, the coil is passed through these holes to secure the text, allowing it to be turned along the direction of the coil and preventing it from easily falling off.

[0003] The binding coil includes a coil body, which consists of several spiral-shaped rings. The distance between two adjacent holes on the text is equal to the distance between two adjacent rings. When the text is fixed by the coil body, a ring passes through each hole.

[0004] After the existing coil body passes through the hole in the text, the two ends of the coil body need to be bent and fixed to the text using the coil pressing mechanism on the binding machine. In this process, the two sides of the text need to be aligned with the coil pressing mechanism to prevent the coil pressing mechanism from damaging the text, which is quite inconvenient.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a text binding coil.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a text binding coil, including a coil body, the coil body being composed of several spiral rings of equal diameter, a collar being provided at one end of the coil body, a circular ring being movably connected to the collar, a limiting rod for abutting the text being provided on the circular ring, and a deformable part being provided on the limiting rod for limiting the end of the limiting rod away from the circular ring to the coil body.

[0008] The present invention is further configured such that: the limiting rod includes an iron core wire and a magnetic tube sleeved outside the iron core wire, the iron core wire is also arranged in the deformation part, and the deformation part also includes a soft rubber sleeve sleeved outside the iron core wire.

[0009] The present invention is further configured such that the outer wall of the soft rubber sleeve is provided with a number of friction points.

[0010] The present invention is further configured such that the end of the deformable part away from the limiting rod is used to bypass the spiral ring and wrap around the magnetic tube.

[0011] The present invention is further configured such that a protective sleeve is fixed at the end of the coil body away from the collar.

[0012] The present invention is further configured such that the coil body is made of PVC material.

[0013] In summary, this utility model has the following beneficial effects:

[0014] After all the spiral rings have passed through the holes in the text, the deformation part is used to restrict one end of the limiting rod to the coil body. At this time, the other end of the limiting rod is restricted by the collar, so that both ends of the limiting rod can be restricted. As a result, when the coil body is subjected to external force and tends to rotate, the limiting rod will come into contact with the text, so that the coil body can not continue to rotate. Thus, the coil body can be restricted to the text. Compared with the existing technology, which requires aligning the two sides of the text with the pressing ring mechanism and using the pressing ring mechanism to complete the limiting of the coil body, the method of restricting the binding coil to the text in this way is more convenient.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Text binding coils, such as Figure 1 and Figure 2As shown, the device includes a coil body 1, which is composed of several spiral rings of equal diameter. One end of the coil body 1 has a collar 2, which is integrally formed with the coil body 1. A circular ring 3 is movably connected to the collar 2. The circular ring 3 has a limiting rod 4 for contacting the text. The limiting rod 4 has a deformation part 5 for restricting the end of the limiting rod 4 away from the circular ring 3 onto the coil body 1. After all the spiral rings have passed through the holes in the text, the deformation part 5 restricts one end of the limiting rod 4 onto the coil body 1. At this time, the other end of the limiting rod 4 is restricted by the collar 2, so that both ends of the limiting rod 4 can be restricted, thereby allowing the coil body to... When subjected to external force and exhibiting a tendency to rotate, the limiting rod 4 will come into contact with the text, preventing the coil body 1 from continuing to rotate. This allows the coil body 1 to be fixed to the text. Compared to the prior art, which requires aligning both sides of the text with the pressing ring mechanism and using the pressing ring mechanism to limit the coil body 1, this binding method of limiting the coil to the text is more convenient. The length of the limiting rod 4 is equal to the distance between two adjacent spiral rings. The end of the deformable part 5 away from the limiting rod 4 is used to bypass the spiral ring and wrap around the magnetic tube. This arrangement ensures the limiting effect of the deformable part 5 on the limiting rod 4 and reduces the possibility of the deformable part 5 detaching from the limiting rod 4.

[0020] like Figure 1 and Figure 2As shown, the limiting rod 4 includes an iron core wire and a magnetic tube sleeved around the iron core wire. The iron core wire is also disposed in the deformation part 5 and the ring 3. The deformation part 5 also includes a soft rubber sleeve sleeved around the iron core wire. The ring 3 also includes a plastic ring sleeved on the iron core wire. One end of the plastic ring is bonded to the magnetic tube. The iron core wire in the ring 3, the limiting rod 4, and the ring 3 are all of the same strand. Both ends of the iron core wire are fixed to the plastic ring and the soft rubber sleeve, respectively. When using the deformation part 5 to limit the limiting rod 4, the soft rubber sleeve is held to make it pass around the spiral ring and wrap around the... At this time, the magnetic tube has an adsorption effect on the iron core wire in the deformation part 5, so that the deformation part 5 can be well restricted on the limiting rod 4 under the action of magnetic force. This allows the end of the limiting rod 4 facing away from the ring 3 to be well restricted, while the other end of the limiting rod 4 is limited by the ring 3, so that the position of the limiting rod 4 will not shift significantly. This allows the coil body 1 to be well restricted on the text. The soft rubber sleeve allows the hand to be separated from the iron core wire in the deformation part 5 when people operate the deformation part 5. The presence of the soft rubber sleeve reduces the possibility of hand injury during the bending of the iron core wire. Simultaneously, the soft rubber sleeve separates the iron core wire in the deformation section 5 from the text, reducing the possibility of damage to the text due to contact between the iron core wire and the text. The magnetic tube ensures the shape of the limiting rod 4 and guarantees the contact between the limiting rod 4 and the text. Several friction points are provided on the outer wall of the soft rubber sleeve, increasing the surface roughness of the soft rubber sleeve and thus improving the maximum static friction between the soft rubber sleeve and the outer wall of the magnetic tube, making it less likely for the soft rubber sleeve to detach when wrapped around the limiting rod 4. A protective sleeve 6 is fixed to the end of the coil body 1 away from the collar 2. Specifically, the protective sleeve 6 is a rubber sleeve bonded to one end of the coil body 1. The presence of the rubber sleeve prevents damage to the text when the end of the coil body 1 contacts the text. The coil body 1 is made of PVC material, which has good wear resistance. Using this material, the coil body 1 can adapt to working environments where it rubs against the text for extended periods, giving the coil body 1 a longer service life.
