Description

TECHNICAL FIELD

[0001] The utility model relates to seal technology field, concretely relates to a novel manual rotary overprint seal. BACKGROUND

[0002] In modern office and daily life, as an important document tool, seal is widely used in contract signing, file certification and personalized identification and many other fields. Traditional seal is usually fixed color, and users often need to prepare multiple color seals in actual use, which brings inconvenience to users.

[0003] With the development of science and technology, some multifunctional seal products appear on the market, which change the color of the seal by replacing the seal surface or ink. However, these improvements often fail to effectively solve the convenience and flexibility of users in the use process.

[0004] In order to solve the above technical problems, the authorization announcement number CN206186566U discloses a color overprint device, which specifically discloses a color overprint device including a seal shell, a middle frame contained in the seal shell, and an elastic member compressed between the seal shell and the middle frame. The color overprint device further includes a seal body and a driving mechanism. The seal body includes a fixed shaft and multiple sides located on the outer periphery of the fixed shaft, and at least two sides have different color seal surfaces. The two ends of the fixed shaft pass through the vertical slots on the two side walls of the middle frame and are supported on the vertical walls on both sides of the seal shell, so that the seal body is suspended in the middle frame. The driving mechanism includes a rotating member on the fixed shaft and a rotating member on the fixed shaft. When the seal body descends with the seal shell, the rotating member drives the side of the seal body to rotate around the fixed shaft under the action of the rotating member, and when the seal body descends to the bottom, the side faces downward to print the seal surface on the target object. When the seal body is pushed up by the spring and the seal shell, the seal body remains unchanged.

[0005] Although the above-mentioned color overprint device can solve the problems of convenience and flexibility, it still has some deficiencies. For example, it forcibly drives the seal surface to rotate when the seal descends through the driving mechanism (dial and rotating member), and the user cannot manually select a specific seal surface. Only the color can be used in sequence, and the flexibility is poor. The mechanism is relatively complex, and the cooperation between the fixed shaft, vertical slot, dial and rotating member requires high precision machining, which increases the manufacturing cost and maintenance difficulty.

[0037] The utility model will be further described below in combination with the drawings and specific embodiments, and the following description is only exemplary and does not limit the protection scope of the utility model.

[0038] As Figures 1-8 shown, a novel manual rotary color seal includes a shell 1, a pressing part 2 housed in the shell 1 and movable up and down, and a barrel 3.

[0039] As Figure 2 shown, a first spring 4 is arranged between the four corner positions of the pressing part 2 and the inner wall of the shell 1; in this embodiment, the first spring 4 is used to reset after the pressing part 2 is pressed down. Specifically, a boss 11 for fixing the first spring 4 is arranged at each of the four corner positions of the inner wall of the shell 1, one end of the first spring 4 abuts against the boss 11, and the other end abuts against the bottom of the pressing part 2, so that after the pressing part 2 is loosened, the first spring 4 can provide a rebounding force to push the pressing part 2 to slide upward and reset. Through the above arrangement, the four first springs 4 can provide stable rebounding force, ensuring that the pressing part 2 can rebound quickly and balancedly after being pressed, and avoiding jamming or tilting caused by unilateral stress.

[0040] As Figures 3-6As shown, the bottom of the pressing part 2 is provided with two connecting arms 21, and the barrel 3 is movably arranged between the two connecting arms 21 through the rotating shaft 5. A plurality of lock holes 210 are arranged on one of the connecting arms 21 and are uniformly distributed along the circumference of the connecting arm 21. In this embodiment, the barrel 3 is fixedly connected with the rotating shaft 5 and is arranged in a suspended manner between the two connecting arms 21. When the rotating shaft 5 rotates, the rotating shaft 5 will synchronously drive the barrel 3 to rotate. In addition, the plurality of uniformly distributed lock holes 210 can provide a plurality of locking angles for the barrel 3.

[0041] As shown in the Figures 2-3 embodiment, the surface of the barrel 3 is provided with a plurality of stamp units 6 of different colors, and an opening 12 is formed in the bottom of the shell 1 for the stamp units 6 to extend outward. In this embodiment, the plurality of stamp units 6 of different colors can provide multi-color overprinting requirements. Specifically, the size of the opening 12 matches the size of the stamp unit 6, so that after the barrel 3 descends, one of the stamp units 6 can pass through the opening 12 and print on the target object.

[0042] As shown in the Figures 3-6 embodiment, a through slot 13 is formed in the side end of the shell 1, one end of the rotating shaft 5 passes through the through slot 13 and is connected with a control part 7 for controlling the rotation or fixation of the barrel 3. The control part 7 includes a knob 71, a rod part 72 inserted into the rotating shaft 5, a second spring 73 sleeved on the rod part 72, and a lock column 74 which can be inserted into the lock hole 210. In this embodiment, the through slot 13 is a vertical strip-shaped slot, and the length direction of the through slot 13 is the stroke of the rotating shaft 5 when it moves up and down.

[0043] Specifically, a slot 75 is formed in the rod part 72, and a pin 76 is arranged on the rotating shaft 5 and passes through the slot 75 and can slide along the length direction of the slot 75. A stop ring 77 is further arranged at the end of the pin 76, and the two ends of the second spring 73 abut against the stop ring 77 and the pin 76, respectively. Through the above arrangement, the control part 7 can be close to or away from the lock hole 210, so as to realize the locking and unlocking of the barrel 3 and the pressing part 2.

[0044] Specific control mode: when the knob 71 is stretched outward, the lock column 74 is separated from the lock hole 210, so that the barrel 3 is synchronously driven to rotate by rotating the knob 71, thereby realizing the color adjustment of the stamp unit 6. When the knob 71 is released, the rod part 72 can slide in the rotating shaft 5 and along the axial direction of the rotating shaft 5 under the action of the second spring 73, so that the lock column 74 can be inserted into the lock hole 210, thereby fixing the barrel 3 on the pressing part 2. Through the above arrangement, the locking structure of the stamp unit 6 is simple, and the operation is also relatively convenient.

[0045] As shown in the Figure 7As shown, the stamp unit 6 is composed of a mounting groove 61 provided in the surface of the stamp unit 6 and a stamp pad 62 provided in the mounting groove 61, and the stamp pad 62 is made of a material with elasticity and capable of storing ink. In the embodiment, the mounting groove 61 is used to fix the stamp pad 62. Specifically, a flange 610 extending to the inner side of the mounting groove 61 is further formed at the edge of the mounting groove 61, so that the stamp pad 62 can be stably clamped in the mounting groove 61. Through the above arrangement, the stability of the stamp pad 62 mounted in the mounting groove 61 can be enhanced, and the situation that the stamp pad 62 is loose or falls off during use can be prevented.

[0046] As shown in Figure 7 , an ink injection hole 63 corresponding to the mounting groove 61 is formed at one end of each stamp unit 6, and a cotton plug 64 is arranged in each ink injection hole 63. In the embodiment, ink can be injected into the mounting groove 61 through the ink injection hole 63, and the cotton plug 64 can block the ink injection hole 63 to prevent the ink from leaking out.

[0047] As shown in Figure 7 , a flow guide plate 65 is further arranged in each mounting groove 63, and the flow guide plate 65 extends from high to low from one end of the ink injection hole 63 to the other end. Through the above arrangement, the ink can flow from one end to the other end of the ink injection hole 63 under the influence of gravity, so that the uniformity of printing can be ensured.

[0048] As shown in Figure 7 , a radial flow guide groove 650 is arranged on the surface of the flow guide plate 65. Through the above arrangement, the ink can flow uniformly into other parts of the stamp pad 62 after being guided by the flow guide groove 650.

[0049] The surface of the stamp pad 62 is further provided with a relief for printing characters or patterns. In the embodiment, the relief is used to print characters or patterns, and the relief provides clear printing effect, meeting the high-quality demand of users for characters or patterns.

[0050] As shown in Figure 8 , a gear mark (not shown in the figure) is arranged on the connecting arm 21 and on the knob 71 corresponding to each lock hole 210. Through the above arrangement, the gear mark on the knob 71 and the gear mark on the connecting arm 21 can be rotated to the corresponding position according to the demand of printing color, so that the rotation angle of the barrel can be adjusted more conveniently.

[0051] In summary, through the locking and disengaging of the barrel 3 by the control part 7, the stable printing demand can be realized in the locked state of the barrel 3, and the multi-color overprint demand can be provided by rotating the control part 7 in the disengaged state. The structure is simple, convenient to operate, and reduces the manufacturing cost and failure rate.

[0052] In addition, by arranging the flow guide plate 65, the ink injected through the ink injection hole 63 can be guided by the flow guide plate 65 and flow into other parts of the printing pad 62, so that the ink is more uniform.

[0053] The utility model is not limited to the above-mentioned implementation, if the various modifications or deformation of the utility model do not deviate from the spirit and scope of the utility model, if these modifications and deformation belong to the right claim and equivalent technical scope of the utility model, then the utility model also intends to contain these modifications and deformation.
