[0026] Embodiments of the present application

[0027] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0028] As shown in FIGS. 1-4, it is a schematic diagram of a multi-ink surface ink stamp provided by an embodiment of the present application, which can be used to stamp multiple different ink surfaces. The multi-ink surface ink stamp of the present embodiment comprises a handle 10, a middle frame 20, an elastic member 30 and an ink surface platform 60, wherein the bottom of the handle 10 and the middle frame 20 is respectively provided with an opening, the handle 10 is sleeved on the outside of the middle frame 20 through the bottom opening thereof, and the middle frame 20 is slidably connected with the two side walls 11 of the handle 10 through two side plates 21; the two side plates 21 of the middle frame 20 are respectively provided with a guide hole 211, and the guide hole 211 is arranged along the direction of the relative sliding between the side plate 21 and the side wall 11; the ink surface platform 60 is supported on the two side walls 11 of the handle 10 through an ink surface platform shaft 63 (for example, each side wall 11 is provided with an axle seat 112 on the inner side thereof, and the end of the ink surface platform shaft 63 is inserted into the axle seat 112) and hung in the middle frame 20, and the ink surface platform 60 is synchronously slid when the handle 10 is slid relative to the middle frame 20. In the present embodiment, the handle 10 and the middle frame 20 are respectively in the shape of a cuboid as a whole, and in order to strengthen the structural strength of the middle frame 20, the bottoms of the two side plates 21 are connected through two connecting strips 23, the two connecting strips 23 and the bottoms of the side plates 21 form a frame shape, and the opening 24 of the bottom of the middle frame 20 is formed between the frame shapes. In actual application, the handle 10 and the middle frame 20 can also be in the shape of a cylinder or an elliptic cylinder, etc.

[0029] Specifically, the elastic member 30 can be a spring, and the two ends of the spring are respectively in abutment with the top plate of the handle 10 and the top plate of the middle frame 20. In this way, when the handle 10 is not pressed, the spring pushes the top plate of the handle 10 away from the top plate of the middle frame 20, and the ink surface platform 60 hung in the middle frame 20 is also away from the opening 24 of the bottom of the middle frame 20; when the handle 10 is pressed, the spring is compressed, the top plate of the handle 10 moves towards the top plate of the middle frame 20, and at the same time, the ink surface platform 60 hung in the middle frame 20 moves downwards along the guide hole 211, and finally passes through the opening 24 of the bottom of the middle frame 20 to realize stamping; when the handle 10 is released, the spring pushes the handle 10 upwards through the elastic restoring force thereof, and at the same time, the ink surface platform 60 also moves upwards along the guide hole 211. In actual use, the elastic member 30 can also use other elastic components, such as a metal spring, etc.

[0030] The printing surface table 60 is a regular polygonal prism, which comprises a plurality of sides parallel to the axial direction of the printing surface table 60, and at least two sides are provided with the printing surface 62 (for example, the printing surface 62 can be pasted or buckled to different sides of the printing surface table 60, respectively). The middle frame 20 is provided with an oil box mounting position 22 below the top plate of the middle frame 20 and opposite to the opening 24 at the bottom of the middle frame 20. The guide hole 211 extends from below the oil box mounting position 22 to the opening 24 at the bottom of the middle frame 20, that is, the printing surface table 60 is suspended between the oil box mounting position 22 and the opening 24 at the bottom of the middle frame 20 and moves up and down between the oil box mounting position 22 and the opening 24 at the bottom of the middle frame 20. When the handle 10 is not pressed, the elastic member 30 pushes the handle 10 to make one of the printing surfaces 62 of the printing surface table 60 supported on the two side walls 11 abut against the oil pad in the oil box 50 in the oil box mounting position 22, so as to realize the ink dipping of the printing surface 62 and facilitate the next stamping.

[0031] The positioning piece 73 on the printing surface table shaft 63 drives the printing surface table 60 to rotate 180° during the downward movement of the printing surface table shaft 63 along the guide hole 211, and the printing surface 62 abutting against the oil box 50 passes through the opening 24 at the bottom of the middle frame 20 to stamp on the target object.

[0032] The multi-printing surface ink-dipping stamp further comprises a buckle 40 and an adjusting assembly, and at least one side plate 21 of the middle frame 20 is provided with a first clamping groove 212. The buckle 40 is arranged on the side wall 11 of the handle 10 and prevents the relative sliding of the handle 10 and the middle frame 20 by being embedded in the first clamping groove 212 (that is, the first clamping groove 212 is located on the running path of the buckle 40), and when the buckle 40 is embedded in the first clamping groove 212, the printing surface table 60 is separated from the oil box 50. The adjusting assembly is connected with the printing surface table 60 and switches the printing surface 62 by pushing the printing surface table 60 to rotate relative to the positioning piece 73 when the buckle 40 is embedded in the first clamping groove 212. Specifically, the side wall 11 of the handle 10 is provided with an assembly hole 111, and the buckle 40 is assembled at the assembly hole 111. When the buckle 40 moves to the position corresponding to the first clamping groove 212 of the middle frame 20 and is pressed, at least a part of the buckle 40 is embedded in the first clamping groove 212 of the side plate 21 of the middle frame 20, so that the handle 10 and the middle frame 20 are relatively fixed, which is convenient for adjusting the printing surface. In particular, the lower part of the buckle 40 and the lower part of the first clamping groove 212 can be inclined surfaces, so that when the buckle 40 is embedded in the first clamping groove 212, the buckle 40 can be popped out of the first clamping groove 212 by continuing to press the handle 10.

[0033] The multi-surface ink stamp can easily realize surface switching even if the surface width is large, and can conveniently replace any surface 62 on the surface table 60. The stamp can meet the ink returning requirement of the surface by using a common ink box. In addition, compared with the method of arranging the surface on a pulley, since each surface 62 is located on a plane, when the surface table 60 is rotated relative to the positioning sheet 73 by the adjusting assembly to adjust the surface, the surface can be adjusted to be in place, and the surface 62 will not be inclined due to the surface table 60 not being rotated to be in place, thereby ensuring that the text and image pattern ink is uniform.

[0034] To ensure the stability of the sliding direction between the handle 10 and the middle frame 20, at least one set of guide rails can be arranged on the inner side of each side wall 11 of the handle 10, and each set of guide rails is composed of two first guide strips 113. Correspondingly, at least one second guide strip 216 is arranged on the side plate 21 of the middle frame 20, and when the handle 10 is sleeved on the middle frame 20, the second guide strip 216 is embedded between the two first guide strips 113 of the same set of guide rails. In particular, two second guide strips 216 are arranged on each side plate 21 of the middle frame 20, and the two second guide strips 216 are respectively located at the edges of the side plate 21. The inner side of each side wall 11 of the handle 10 is respectively provided with two corresponding sets of guide rails.

[0035] In an embodiment of the present application, the surface table 60 is a regular triangular prism, and the surface table 60 includes three rectangular sides parallel to the axial direction, and three surfaces 62 with different text and image patterns are respectively fixed on the three rectangular sides. Through the above structure, the multi-surface ink stamp can realize the stamping of three different text and image patterns.

[0036] In another embodiment of the present application, as shown in FIG. 6, the surface table 60 is a regular quadrangular prism, and the surface table 60 includes four rectangular sides parallel to the axial direction, and four surfaces 62 with different text and image patterns are respectively fixed on the four rectangular sides. Through the above structure, the multi-surface ink stamp can realize the stamping of four different text and image patterns.

[0037] In actual application, the surface table 60 can also be a regular pentagonal prism or a regular hexagonal prism, but this will greatly increase the width of the multi-surface ink stamp.

[0038] In an embodiment of the present application, to facilitate the adjustment of the surface 62, when the buckle 40 is embedded in the first clamping groove 212, one side of the surface table 60 faces the ink box 50 and is separated from the ink box 50. In this way, during the rotation of the surface table 60 to adjust the surface 62, the surface table 60 will not be unable to rotate due to abutting against the ink box 50.

[0039] In one embodiment of the present application, the positioning piece 73 is in the form of a strip, and comprises a first positioning member 731, a shaft hole 732, and a first sliding guide member 733. The positioning piece 73 is assembled between the side plate 21 of the middle frame 20 and the end plate 64 of the printing surface table 60 via the printing surface table shaft 63 passing through the shaft hole 732. The first positioning member 731 is located on the surface of the positioning piece 73 facing the printing surface table 60 and away from the shaft hole 732, and the first sliding guide member 733 is located on the surface of the positioning piece 73 facing the side plate 21 of the middle frame 20.

[0040] Correspondingly, the end surface of the printing surface table 60 facing the side plate 21 of the middle frame 20 has a plurality of sets of second positioning members 721 corresponding to different printing surfaces 62 respectively. For example, when the printing surface table 60 is in the form of a triangular prism, the end surface of the printing surface table 60 has three sets of second positioning members 721 corresponding to the three printing surfaces 62 respectively, and when the printing surface table 60 is in the form of a quadrangular prism, the end surface of the printing surface table 60 has four sets of second positioning members 721 corresponding to the four printing surfaces 62 respectively. The surface of the side plate 21 of the middle frame 20 facing the printing surface table 60 has a second sliding guide member 215, and during the upward and downward movement of the printing surface table 60 along the guide hole 211 driven by the printing surface table shaft 63, the positioning piece 73 is driven to rotate by the cooperation of the second sliding guide member 215 and the first sliding guide member 733, and the printing surface table 60 is driven to rotate by the cooperation of the first positioning member 731 and one set of second positioning members 721.

[0041] By means of the positioning piece 73, in combination with the second positioning members 721 on the printing surface table 60 and the second sliding guide member 215 on the middle frame 20, the printing surface table 60 can be automatically rotated during the upward and downward movement, thereby achieving ink dipping and stamping.

[0042] In particular, in order to better drive the rotation of the printing surface table 60, the multi-printing surface ink-dipping stamp described above can comprise two positioning pieces 73, and the two positioning pieces 73 are assembled at the two ends of the printing surface table 60 respectively, so that the printing surface table 60 can be synchronously driven to rotate from the two ends of the printing surface table 60. When the adjustment assembly drives the printing surface table 60 to rotate relative to the positioning piece 73, the first positioning member 731 cooperates with different sets of second positioning members 721, and by the cooperation of the first positioning member 731 and different sets of second positioning members 721, the ink dipping and stamping of the corresponding printing surface 62 are achieved.

[0043] In one embodiment of the present application, the first positioning member 731 is composed of a plurality of positioning pins distributed along the circumference of the shaft hole 732 (each positioning pin is arranged along the axial direction of the shaft hole 732), and the second positioning member 721 is composed of a plurality of grooves corresponding to the positioning pins respectively. When the positioning sheet 73 is assembled between the side plate 21 of the middle frame 20 and the end plate 64 of the printing platform 60, the positioning pins are embedded in the grooves. In this way, when the positioning sheet 73 rotates along the shaft hole 732, the positioning pins embedded in the grooves can drive the printing platform 60 to rotate synchronously. In particular, the first positioning member 731 includes two positioning pins distributed at 180°, and correspondingly, each group of the second positioning member 721 includes two grooves distributed at 180°, so that the positioning sheet 73 can apply force to the printing platform 60 on both upper and lower sides of the printing platform shaft 63, and better drive the printing platform 60 to rotate. In addition, in actual application, the first positioning member 731 can also be composed of a plurality of grooves distributed along the circumference of the shaft hole 732, and correspondingly, the second positioning member 721 is composed of a plurality of positioning pins corresponding to the grooves respectively.

[0044] In one embodiment of the present application, the guide hole 211 on the side plate 21 of the middle frame 20 includes a first straight segment 2111, an arc segment 2112 and a second straight segment 2113 connected in sequence along the sliding direction of the handle 10, and the first straight segment 2111 and the second straight segment 2113 are located on the same straight line. Correspondingly, the first sliding guide member 733 on the positioning sheet 73 is composed of a straight slot arranged along the length direction of the positioning sheet 73, and the second sliding guide member 215 is composed of a slider embedded in the straight slot, and the slider is located inside the arc segment 2112 (for example, the center position of the arc segment 2112). In particular, in order to make the slider slide smoothly in the straight slot, the slider can be in a cylindrical shape. During the downward and upward movement of the printing platform 60 driven by the printing platform shaft 63, when the printing platform shaft 63 passes through the arc segment 2112, the slider sliding in the straight slot pushes the positioning sheet 73 to rotate, and at the same time, the positioning sheet 73 pushes the printing platform 60 to rotate synchronously.

[0045] Of course, in actual application, the guide hole 211 on the side plate 21 of the middle frame 20 can also be in a single straight line shape, and the first sliding guide member 733 on the positioning sheet 73 is composed of an arc slot. Although the positioning sheet 73 can also rotate during the upward and downward movement of the printing platform shaft, the arc slot will cause the size of the positioning sheet 73 to be relatively large. In addition, the first sliding guide member 733 can also be composed of a slider on the positioning sheet 73, and correspondingly, the second sliding guide member 215 is composed of an arc slot on the side plate 21 of the middle frame 20.

[0046] To facilitate the relative rotation between the positioning sheet 73 and the printing surface platform 60, in one embodiment of the present application, at least one elastic arm 734 is arranged on the positioning sheet 73, the first positioning member 731 is located on the elastic arm 734 (for example, at the free end of the elastic arm 734), and the first positioning member 731 is separated from the second positioning member 721 by the deformation of the elastic arm 734 along the axial direction of the printing surface platform 60. That is, when the positioning sheet 73 and the printing surface platform 60 rotate relative to each other, the elastic arm 734 deforms in a direction away from the end surface 64 of the printing surface platform 60, thereby facilitating the separation of the first positioning member 731 and the second positioning member 721; and when the positioning sheet 73 and the printing surface platform 60 remain fixed, the first positioning member 731 is pressed and fixed with the second positioning member 721 by the elastic force of the elastic arm 734.

[0047] Specifically, the elastic arm 734 can be arranged along the radial direction of the shaft hole 732, and the free end of the elastic arm 734 is adjacent to the shaft hole 732. Moreover, when the positioning sheet 73 has two first positioning members 731, the positioning sheet 73 includes two elastic arms 734, and the two elastic arms 734 are distributed at intervals of 180° on the outer periphery of the shaft hole 732. In particular, the two elastic arms 734 can be arranged in the direction of the straight slot, respectively, as shown in FIG. 4. Alternatively, the two elastic arms 734 can be located above and below the shaft hole, respectively, and arranged in a direction perpendicular to the straight slot, respectively, as shown in FIG. 6.

[0048] In combination with FIG. 5, in one embodiment of the present application, the adjustment assembly includes a driven gear 72 and a driving gear 71, wherein the driven gear 72 is located on the end surface 64 of the printing surface platform 60, and the driving gear 71 is rotationally connected to the positioning sheet 73, the driving gear 71 is engaged with the driven gear 72, and when the buckle 40 is embedded in the first clamping groove 212, the driving gear 71 rotates with the positioning sheet 73 to a position at least partially exposed from the middle frame 20. Through the above structure, while facilitating the adjustment of the printing surface by rotating the adjustment assembly, the space occupied by the adjustment assembly is relatively small, which is beneficial to the miniaturization of the multi-printing surface ink stamp.

[0049] Specifically, to reduce parts and assembly procedures, the driven gear 72 can be integrated with the end surface 64 of the printing surface platform 60, that is, the driven gear 72 is composed of a protrusion protruding from the end surface 64. At the same time, the second positioning member 721 is composed of a groove on the driven gear 72.

[0050] As shown in FIG. 4, the surface of the positioning sheet 73 facing the printing surface table 60 has a pin shaft 735 which is integral with the positioning sheet 73, and the driving gear 71 is assembled to the pin shaft 735 through the center hole 711, i.e. the pin shaft 735 constitutes the center shaft of the driving gear 71. The pin shaft 735 can be composed of two semicircular elastic columns, and the free ends of the elastic columns have sliding guide surfaces, through which the driving gear 71 is assembled to the pin shaft 735. The assembly structure of the driving gear 71 can also reduce the parts and the assembly process.

[0051] In order to save space, the driving gear 71 is arranged between the positioning sheet 73 and the end surface 64 of the printing surface table 60, and the center shaft (i.e. the pin shaft 735) of the driving gear 71 is arranged along the length direction of the positioning sheet 73. This structure can make the positioning sheet 73 drive the driving gear 71 to protrude from the middle frame 20 as much as possible when the buckle 40 is inserted into the first clamping groove 212, thereby facilitating the printing surface adjustment operation.

[0052] In an embodiment of the present application, at least one side plate 21 of the middle frame 20 has a second clamping groove 213 which is located on the running path of the buckle 40, and when the buckle 40 is inserted into the second clamping groove 213, the printing surface 62 of the printing surface table 60 is separated from the oil box 50 in the oil box mounting position 22, and the oil box mounting position 22 is completely exposed from the handle 10, thereby achieving the installation and disassembly of the oil box 50.

[0053] In addition, at least one side plate 21 of the middle frame 20 can also have a third clamping groove 214 which is also located on the running path of the buckle 40, and when the buckle 40 is inserted into the third clamping groove 214, the printing surface 62 of the printing surface table 60 is close to the bottom opening of the middle frame 20, thereby facilitating the installation and disassembly of the printing surface 62.

[0054] The above description is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any changes or replacements within the technical range disclosed by the present application can be easily thought by those skilled in the art, and should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
