Description

Technical Field

[0001] This invention relates to the field of binding machine technology, specifically a rotatable riveting head for binding. Background Technology

[0002] The main function of a binding machine is to punch holes in documents that need to be bound, and then use rivet tubes to bind them. Because it is used more by financial personnel, for example, when they need to bind financial documents, the binding machine can also be called a financial binding machine. However, it is not limited to use by financial personnel; it can also be used in other scenarios where binding is required.

[0003] As can be seen from the above, the binding machine uses a riveting tube to achieve binding. The core component of the riveting process is the rivet head. In the current structure, the rivet head is a fixed structure design with an unchanging orientation, which poses a risk of burns during user operation. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and propose a rotatable rivet head for binding that can be switched between a hidden and a used state, thereby helping to reduce the safety hazard of burns.

[0005] Compared with the prior art, the present invention proposes a rotatable rivet head for binding, including a housing, a heating element, and a rivet head body. The heating element and the rivet head body are both installed in the housing to form the rivet head. The exposed part of the rivet head body is located at the lower end of the housing. It also includes a support and a first driving structure. The housing and the support are rotatably connected. The first driving structure is driven to rotate the housing so that the rivet head rotates. The rivet head rotation can switch between a hidden position and a working position. In the hidden position, the rivet head rotates inward toward the support so that the lower end of the housing faces inward toward the support, thereby hiding the exposed part of the rivet head body. In the working position, the rivet head rotates outward toward the support so that the lower end of the housing faces downward, thereby making the exposed part of the rivet head body face downward in the working position.

[0006] In some embodiments, the support is further provided with a cover that covers the rivet head and has an opening at the working position of the rivet head, through which the exposed portion of the rivet head body is in a working position.

[0007] In some embodiments, the first drive structure adopts a gear structure, a gear and rack structure, a cam structure, a rocker arm structure, a connecting rod structure, a lead screw structure, or an electromagnetic rotation structure.

[0008] In some embodiments, when a gear and rack structure is used, a first gear is provided on the side of the housing, and a first rack is provided on the support. The reciprocating movement of the first rack drives the reciprocating rotation of the first gear, and the reciprocating rotation of the first gear drives the housing to reciprocate. The reciprocating rotation of the housing allows the rivet head to switch between a hidden position and a working position.

[0009] In some embodiments, a locking mechanism is also included, which cooperates with the housing and, in the working position, is connected to the housing to lock the housing in a position so that it cannot be rotated.

[0010] In some embodiments, the locking mechanism includes a locking bolt driven by a second drive structure and a locking part located on the housing. In the working position, the locking bolt is connected to the locking part to lock the housing so that it cannot be rotated.

[0011] In some embodiments, the first driving structure and the second driving structure are linked. When the first driving structure switches from the hidden position to the working position, the second driving structure drives the locking bolt to connect and lock with the locking part when the rivet head reaches the working position. When the first driving structure switches from the working position to the hidden position, the second driving structure drives the locking bolt to disengage from the locking part before the rivet head reaches the hidden position to release the lock.

[0012] In some embodiments, the second drive structure includes a second rack and a second gear disposed on the locking bolt, wherein the second rack drives the locking bolt to reciprocate or extend and retract via the second gear.

[0013] In some embodiments, the first drive structure also adopts a gear and rack structure, which includes a first rack and a first gear disposed in the housing. The first rack and a second rack are linked together. When the first rack moves, the second rack moves together to switch between locked and unlocked states.

[0014] In some embodiments, the second rack is also connected to a return spring, which resets the second rack during unlocking, thereby resetting the locking bolt and unlocking it.

[0015] Compared with the prior art, the present invention has the following advantages when adopting the above structure: The technical solution disclosed herein includes a support and a first driving structure. The housing is rotatably connected to the support, and the first driving structure is transmissionally connected to the housing. The first driving structure is used to drive the housing to rotate so that the rivet head rotates. The rivet head rotation can switch between a hidden position and a working position. In the hidden position, the rivet head rotates towards the inside of the support so that the lower end of the housing faces the inside of the support, thereby hiding the exposed part of the rivet head body. In the working position, the rivet head rotates towards the outside of the support so that the lower end of the housing faces downward, thereby making the exposed part of the rivet head body face downward in a working position. Therefore, it is possible to switch between the hidden and working states, which helps to reduce the safety hazard of burns. Attached Figure Description

[0023] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The embodiments described below are merely examples, and other obvious variations will arise for those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0024] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0025] like Figures 1 to 6As shown, a rotatable rivet head for binding is disclosed, including a housing 1, a heating element, and a rivet head body 3. The heating element and the rivet head body 3 are both installed in the housing 1 to form the rivet head. The exposed part of the rivet head body 3 is located at the lower end of the housing 1. It also includes a support 2 and a first driving structure. The housing 1 and the support 2 are rotatably connected by a rotating shaft 4. The first driving structure is connected to the housing 1 for transmission. The first driving structure is used to drive the housing 1 to rotate so that the rivet head rotates. The rivet head rotation can switch between a hidden position and a working position. In the hidden position, the rivet head rotates towards the inside of the support 2 so that the lower end of the housing 1 faces the inside of the support 2, thereby hiding the exposed part of the rivet head body 3. In the working position, the rivet head rotates towards the outside of the support 2 to a position where the lower end of the housing 1 faces downward, thereby making the exposed part of the rivet head body 3 face downward in the working position.

[0026] In some embodiments, such as Figure 1 As shown, the support 2 is also provided with a cover 5, which covers the rivet head and has an opening 6 at the working position of the rivet head. Through the opening 6, the exposed part of the rivet head body 3 is in a working position. In this way, the side facing the user is better protected from burns by the cover 5.

[0027] In some embodiments, the first drive structure adopts a gear structure, a gear and rack structure, a cam structure, a rocker arm structure, a connecting rod structure, a lead screw structure, or an electromagnetic rotation structure. This example primarily illustrates a gear and rack structure, but any first drive structure suitable for this disclosure can be used.

[0028] In some embodiments, such as Figure 5 , 6 As shown, the side of the housing 1 is provided with a first gear 7, and the support 2 is provided with a first rack 8. The reciprocating movement of the first rack 8 drives the reciprocating rotation of the first gear 7, and the reciprocating rotation of the first gear 7 drives the housing 1 to reciprocate. The reciprocating rotation of the housing 1 allows the rivet head to switch between a hidden position and a working position.

[0029] In some embodiments, a locking mechanism is also included, which cooperates with the housing 1. In the working position, the locking mechanism is connected to the housing 1 to lock the housing 1 so that it cannot rotate. In this way, the rotatable riveting head is locked in the working state, which is beneficial to the operation of the rotatable riveting head.

[0030] In some embodiments, such as Figure 4 , 5 As shown, the locking mechanism includes a locking bolt 9 driven by a second drive structure and a locking part 10 located on the housing 1. In the working position, the locking bolt 9 is connected to the locking part 10 to lock the housing 1 so that it cannot rotate.

[0031] In this example, the locking part 10 uses a locking groove, which makes it easier for the locking bolt 9 to lock / unlock more quickly.

[0032] In some embodiments, such as Figure 4 , 5 As shown, the second drive structure includes a second rack 11 and a second gear 12 disposed on the locking bolt 9. The second rack 11 drives the locking bolt 9 to swing back and forth or extend and retract through the second gear 12. In this example, it is set to swing, which has better efficiency.

[0033] Of course, the locking mechanism can be any other mechanism, and any locking mechanism applicable to this disclosure may be adopted.

[0034] In some embodiments, the first drive structure and the second drive structure are linked. When the first drive structure switches from a hidden position to a working position, the second drive structure drives the locking bolt 9 to engage with the locking part 10 when the rivet head reaches the working position. When the first drive structure switches from the working position to a hidden position, the second drive structure drives the locking bolt 9 to disengage from the locking part 10 before the rivet head reaches the hidden position, thus unlocking the lock. For example, both the first drive structure and the second drive structure are driven by electric motors, so the two electric motors can be linked. Of course, they can also be mechanically linked. For example, the first drive structure also adopts a gear and rack structure, which includes a first rack 8 and a first gear 7 disposed on the housing 1. The first rack 8 and the second rack 11 are linked. When the first rack 8 moves, the second rack 11 moves to switch between locked and unlocked states.

[0035] The linkage between the first rack 8 and the second rack 11 is, for example, both driven by the drive wheel 14. The drive wheel 14 can drive the first rack 8 and the second rack 11 through a cam curve, and the linkage relationship between the two is defined by the cam curve.

[0036] Of course, the linkage structure can also be other structures, and any linkage structure applicable to this disclosure can be adopted.

[0037] In some embodiments, such as Figure 4 , 5 As shown, the second rack 11 is also connected to a return spring 13. During unlocking, the return spring 13 resets the second rack 11, thereby resetting the locking bolt 9 and unlocking it. This results in higher unlocking efficiency.

[0038] When understanding this disclosure, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that's understood, so I won't go into details here.

[0039] The above description is merely an illustrative embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of the present invention are included within the scope of protection of the present invention.
