The seal is widely applied to various industries such as banks, governments, enterprises, schools and the like, is used as the most direct and most effective legal voucher, has great significance in the various industries for the standard use and safe keeping of the seal, and has high use frequency in the daily operation process. Based on above-mentioned current situation, the user relatively tends to the device that can automatic stamping at present, but the automatic stamping device that can automatic stamping of pressing that exists among the prior art, the setting of this kind of device internal work mechanism is comparatively complicated usually, and usually whole size is great (need reserve the space that the rotation of seal inside and different states stop), and the frequent flip angle of seal, it is inhomogeneous to lead to the ink mark on seal surface to distribute easily, the stamp shows when stamping next time is unclear, to the great seal of dead weight of brass seal class, the mechanism frequently overturns also easy wearing and tearing card pause etc.. The seal is required to perform a series of actions, so that the seal is not beneficial to protecting the seal surface of the seal and is not beneficial to the long-term stable use of the seal.

As shown in fig. 1 and fig. 2, an ink returning mechanism 100 according to an embodiment of the present disclosure includes a support 110 and a sleeve 120 slidably sleeved on the support 110, a stamp mounting fixture 130 for clamping a stamp is disposed in a stamp region 112 of the support 110, the stamp mounting fixture 130 is fixedly connected to the sleeve 120, and a stamp region is formed at one end of the support 110; the orthographic projection of the seal stamping surface clamped by the seal clamping device 130 is positioned in the stamping area 112, a protecting cover 140 used for abutting and covering the seal stamping surface is further arranged in the sleeve 120, and the protecting cover 140 is rotationally connected with the support 110 and the sleeve 120 through a fulcrum 142; the pushing sleeve 120 slides in a direction approaching the stamping region 112, the cover 140 rotates along with the fulcrum 142 to expose the stamping surface, and the stamp moves linearly to the stamping region 112 of the support 110 for stamping operation.

Specifically, the support 110 and the sleeve 120 slidably sleeved on the support 110 are used to facilitate the stamping operation of the stamp in the support 110 when the support 110 and the sleeve 120 slide relatively. The seal is clamped in the seal-mounting fixture 130, the seal-mounting fixture 130 is disposed in the support 110, and the seal-mounting fixture 130 is fixedly connected to the sleeve 120, so that the seal and the sleeve 120 are relatively fixed, and when the sleeve 120 and the support 110 slide relatively, the seal is driven by the seal-mounting fixture 130 to synchronously move.

The base can be arranged on the support 110, wherein the base plays a role of stable support, and when stamping is performed, the base is attached to the surface to be stamped, so that the stamping part can be flattened better, and the stamping effect is improved. Through the stamping region 112 (the via hole that makes the seal pass through) of dividing on the surface of base, make the seal stamp face of adorning the anchor clamps 130 centre gripping towards the base and the projection is located stamping region 112 to the seal smoothly passes through stamping region 112 when stamping, and when the seal withdrawed in support 110, the base played the effect of protection to the part in the support 110. In which the feature of a base is not required, the support 110 itself has a stable supporting structure, and the required stamping region 112 is formed on the support 110, so that the support 110 can support and slide the sleeve 120 relatively along the support 110.

It can be understood that, since the sleeve 120 is sleeved on the support 110 and slidably connected with the support 110, the sealing fixture 130 is disposed in the support 110 and connected with the sleeve 120 through other auxiliary fasteners. It should be noted that the arrangement form between the seal attaching jig 130 and the sleeve 120 is not particularly limited in the embodiment of the present application as long as a stable connection can be ensured. For example, as shown in fig. 2 and 7, a bypass chute 114 may be provided on the bracket 110, and the extending direction of the bypass chute 114 coincides with the sliding direction of the sleeve 120. In this way, the affixing jig 130 can be connected to the sleeve 120 through the escape chute 114 by a connecting member to ensure stable connection and normal movement of the affixing jig 130. The sealing fixture 130 can also be directly connected with one end of the sleeve 120, and the sealing fixture 130 is extended into the support 110, so as to avoid the influence on the connection between the sealing fixture 130 and the sleeve 120 when the sleeve 120 and the support 110 slide relatively.

In addition, the protecting cover 140 is rotatably connected with the support 110 and the sleeve 120 through the support shaft 142, the protecting cover 140 is abutted and covered on the seal surface of the seal in the initial state of the ink returning mechanism 100, and when the seal ink is arranged in the protecting cover 140, the ink can be automatically returned without being stained with the seal ink once again in the seal process. During the stamping operation when the support 110 and the sleeve 120 slide relatively, i.e. the sleeve 120 is pushed to slide toward the stamping region 112, the protective cover 140 rotates along with the support shaft 142 to expose the stamping surface of the stamp, and the stamp moves linearly to the stamping region 112 to perform the stamping operation.

The ink return mechanism 100 provided by the embodiment of the application is provided with the sleeve 120 which is sleeved on the support 110 through the support 110 and the sliding sleeve, when stamping is performed, the stamping region 112 corresponds to the surface to be stamped, and the sleeve 120 slides relative to the support 110, so that a stamp arranged on the stamping clamp 130 in the sleeve 120 can be stamped through the stamping region 112. In the above operation process, the sleeve 120 slides in a direction close to the stamping region 112, so as to drive the stamping fixture 130 and the stamp clamped on the stamping fixture 130 to move synchronously, and meanwhile, the protecting cover 140 abutting on and covering the stamp face rotates along with the fulcrum 142 to expose the stamp face, so as to realize the required stamping operation. After the stamping is completed, the sleeve 120 slides in a direction away from the stamping region 112, and at this time, the cover 140 rotates in the reverse direction via the support shaft 142 until it abuts against and covers the stamp face, thereby achieving the purpose of protecting the stamp. Wherein, when setting up the stamp-pad ink on protecting cover 140, because protecting cover 140 butt covers the seal stamp face, be favorable to stamp-pad ink and the laminating of seal stamp face, realize the automatic mesh of ink that returns to in order to can directly stamp the operation next time, need not additionally to be stained with and get the stamp-pad ink again. Simultaneously, adopt above-mentioned structure, need not to protect the seal to operations such as upset the seal, need not to occupy the required space of seal upset, be favorable to promoting the compactedness of structure to seal the seal face under the state of non-stamping, protect the seal face.

As shown in fig. 3 and 4, the holder 110 is provided with a turning groove 116, the sleeve 120 is provided with a slide groove 122, the support shaft 142 of the cover 140 is provided through the turning groove 116 and the slide groove 122, respectively, and the cover 140 is moved and turned in a direction approaching the affixing area 112 along the turning groove 116 and the slide groove 122 in accordance with the sliding of the sleeve 120 toward the affixing area 112.

Specifically, since the supporting shaft 142 of the cover 140 is disposed through the flipping slot 116 and the sliding slot 122, when the sleeve 120 slides toward the stamping region 112, the overlapping position between the flipping slot 116 and the sliding slot 122 changes, so as to drive the supporting shaft 142 to move in the flipping slot 116, and the relative position between the supporting shaft and the sliding slot 122 also changes correspondingly. And in the process that the support shaft 142 moves along the turning groove 116, that is, in the process that the protective cover 140 moves towards the stamping area 112, the protective cover 140 synchronously turns over to give way to the stamp, so that the stamp can smoothly pass through the stamping area 112 for stamping operation. It will be appreciated that when the sleeve 120 is slid away from the stamping region 112, the cover 140 is reversed to return to its original position in overlying abutment with the stamp face.

With continued reference to fig. 3 and 4, the turning groove 116 of the bracket 110 is an arc-shaped groove, the sliding groove 122 of the sleeve 120 includes a straight line portion 1222 and a curved portion 1224 connected to the end of the straight line portion 1222, the protruding direction of the curved portion 1224 is opposite to the protruding direction of the arc-shaped groove, the straight line portion 1222 extends along the direction of relative movement between the sleeve 120 and the bracket 110, the straight line portion 1222 coincides with the lower end projection position of the arc-shaped groove, and the end of the curved portion 1224 coincides with the upper end projection position of the arc-shaped groove.

Specifically, the straight line segment 1222 coincides with the lower end projection position of the arc-shaped slot, that is, the lower end of the arc-shaped slot coincides with the projection position of the head end of the bent segment 1224 (the head end of the bent segment 1224 is the end connected with the straight line segment 1222, and the tail end of the bent segment 1224 is the end far away from the straight line segment 1222), and the tail end of the bent segment 1224 coincides with the projection position of the upper end of the arc-shaped slot. In the above manner, in the initial state of the ink returning structure, the supporting shaft 142 is located at the upper end of the arc-shaped groove, and the upper end of the arc-shaped groove overlaps with the end of the bending section 1224, and along with the sliding of the sleeve 120 in the direction of the stamping region 112, the overlapping position between the bending section 1224 and the arc-shaped groove changes, so that the supporting shaft 142 moves to the lower end of the arc-shaped groove along the upper end of the arc-shaped groove, and when the supporting shaft 142 moves, the protecting cover 140 is turned over to give way to the stamp, thereby ensuring the smooth movement of the stamp and avoiding interference. When the fulcrum 142 moves along the upper end of the arc-shaped slot to the lower end of the arc-shaped slot, the protective cover 140 rotates 90 degrees, i.e., the plane of the protective cover 140 is turned from perpendicular to the sliding direction to parallel to the sliding direction. After the cover 140 is rotated 90 °, the straight section 1222 and the supporting shaft 142 are moved oppositely, and the straight section 1222 does not lift the force for moving the supporting shaft 142 relative to the arc-shaped groove, so that the cover 140 remains in the turned state when the straight section 1222 and the supporting shaft 142 are moved oppositely. When the sleeve 120 is slid away from the stamping region 112 until the fulcrum 142 and the curved portion 1224 again engage, the protective cover 140 is turned to an initial state abutting against the stamping face under the cooperation of the curved portion 1224 and the curved slot.

As shown in fig. 5, the bending section 1224 includes an arc section 1224a and a parallel section 1224b connected to the end of the arc section 1224a, and the fulcrum 142 of the protective cover 140 slides on the parallel section 1224b to adjust the abutting force between the protective cover 140 and the covered stamp face.

Specifically, in the above manner, when the sleeve 120 moves in the direction approaching the stamping region 112, the fulcrum 142 is located at the end of the bending section 1224 when the fulcrum 142 moves relatively to the bending section 1224 in the initial stage of the movement of the sleeve 120. At this time, when the sleeve 120 slides relative to the bracket 110, the distance of the fulcrum 142 moving in the vertical direction relative to the sleeve 120 does not change the state of the protective cover 140, and the protective cover 140 remains horizontal. Thus, at the initial stage that sleeve 120 slided along support 110, protecting cover 140 keeps the current state unchangeable (promptly relative support 110 keeps stationary), along with the relative motion between sleeve 120 and the support 110 for protecting cover 140 compresses tightly with the seal stamp face, when being provided with the stamp-pad ink in protecting cover 140, is favorable to the better contact of stamp-pad ink and seal stamp face, produces the ink dipping action of certain pressure in the earlier stage of the action of stamping, with the definition when guaranteeing to stamp. The supporting shaft 142 moves to the arc 1224a along with the movement of the sleeve 120, and slides relative to the arc 1224a, and during the sliding process of the supporting shaft 142 from the arc 1224a to the straight-line section 1222, the supporting shaft 142 moves relative to the arc 1224a and the turning groove 116, at this time, the protecting cover 140 is limited by the guiding through groove 1462 and the supporting shaft 142 which are arranged on the fixing portion 146 and perpendicular to the plane of the cover 144, so that the protecting cover 140 is turned over to expose the stamping surface, and the stamping process is smoothly performed. After the stamping is completed, the process of recovering to the initial state between the sleeve 120 and the support 110, the protecting cover 140 moves reversely, so that the protecting cover 140 recovers to the horizontal state, a certain gap is formed between the protecting cover and the stamp account surface, the stamp is prevented from being dipped in ink all the time, and the stamping effect is influenced by absorbing excessive ink.

As shown in fig. 4, 6 and 7, the protective cover 140 includes a cover body 144 and a fixing portion 146 connected to each other, the supporting shaft 142 passes through the fixing portion 146 and is parallel to the plane of the cover body 144, guide through slots 1462 are respectively formed at two opposite ends of the fixing portion 146 for passing through the supporting shaft 142, and the extending direction of the guide through slots 1462 is perpendicular to the plane of the cover body 144; guide protrusions 118 are further disposed on two opposite sides of the side wall of the bracket 110, and the guide protrusions 118 are located in the guide through slots 1462, so that the guide protrusions 118 slide relative to the guide through slots 1462.

Specifically, when the cover 144 of the protective cover 140 is turned over, a force required for turning over needs to be provided from the fixing portion 146, and the fixing portion 146 is provided with a guiding through slot 1462 and a fulcrum 142 passing through the fixing portion 146. As the position of the overlap between the arcuate slot and the curved section 1224 changes, the relative position between the fulcrum 142 and the arcuate slot is caused to change. Because the guide protrusion 118 is always located in the guide through slot 1462, and the position of the guide protrusion 118 is fixed, and the position of the fulcrum shaft 142 is also located in the extending direction of the guide through slot 1462, when the position of the fulcrum shaft 142 changes, the guide through slot 1462 and the guide protrusion 118 slide relative to each other, and the extending direction of the guide through slot 1462 changes, that is, the protective cover 140 performs a flipping motion. It will be appreciated that the connection between the two points forms a straight line, and in the present embodiment, the guide boss 118 and fulcrum 142 correspond to two points forming a straight line, and when one of the points is stationary and the other point moves relative to the arcuate slot, the direction of the straight line formed between the two points is deflected.

By providing the guide through-groove 1462 perpendicular to the plane of the cover 144 on the fixing portion 146, in the initial state, the extending direction of the guide through-groove 1462 is parallel to the sliding direction of the sleeve 120, and the protective cover 140 abuts against and covers the seal surface. When stamping is needed, the sleeve 120 moves towards the direction close to the stamping region 112 and drives the stamping fixture 130 and the stamp arranged on the stamping fixture 130 to move synchronously, and when the overlapping position between the arc-shaped groove and the bending section 1224 changes in the process that the sleeve 120 is close to the stamping region 112, the relative position between the fulcrum shaft 142 and the turnover groove 116 (arc-shaped groove) is driven to change. Since the position of the guide protrusion 118 is fixed, the extending direction of the guide through slot 1462 is deflected, and the cover 144 is rotated. In the process of deflection in the extending direction of the guiding through groove 1462, relative sliding occurs between the guiding protrusion 118 and the guiding groove, so that the guiding through groove 1462 and the guiding protrusion 118 are prevented from being jammed, and the stable turnover of the protecting cover 140 is ensured. By adopting the above form, when the fulcrum 142 slides relative to the arc-shaped groove, the fixing portion 146 is driven to move in the direction away from the side wall of the bracket 110, so that the fixing portion 146 is prevented from interfering with the bracket 110 when rotating, and the stable turning of the protective cover 140 is ensured.

With the sequential pushing of the sleeve 120 toward the stamping region 112, until the support shaft 142 moves to the lower end of the arc-shaped slot, the turning of the protecting cover 140 is completed, and at this time, the protecting cover 140 completely moves out of the path of the stamp, thereby avoiding affecting the stamping process of the stamp. With the sleeve 120 continuing to slide, the supporting shaft 142 slides along the straight line segment 1222, the position of the supporting shaft 142 at the lower end of the arc-shaped groove is kept unchanged, and the state of the protecting cover 140 after being turned is also kept unchanged, until the sleeve 120 moves in the direction away from the stamping area 112 after the stamping is completed, the protecting cover 140 reversely moves to return to the initial state, which is the reverse process of the stamping process and is not described herein again.

In an alternative embodiment of the present application, a cushioning layer is provided on the side of the cover 144 facing the stamp face. Thus, when the cover 144 abuts against and covers the seal surface, the seal surface is protected, and damage caused by rigid contact is avoided. By way of example, the buffer layer can be a sponge layer with printing ink, and the buffer layer can achieve the effect of automatically returning ink while achieving a protection effect.

As shown in fig. 2 and 6, an ink cartridge 148 is provided on the side of the cover 144 facing the stamp face for sucking ink from the stamp face when the cover 140 covers the stamp face.

Specifically, by arranging the stamp-pad ink box 148 on the side of the cover 144 facing the stamp face, the stamp-pad ink box 148 can be in contact with the stamp face after the stamp is completed and the sleeve 120 slides away from the stamping region 112 and is in place, so as to protect the stamp face. And the adoption of the stamp-pad ink box 148 is beneficial to ensuring the cleanliness of the ink returning mechanism 100 and avoiding the stamp-pad ink from polluting other areas.

Referring to fig. 2 and fig. 6, the side edge of the ink cartridge 148 and the side edge of the cover 140 are respectively provided with a fastening portion 149, and the ink cartridge 148 and the cover 140 are fastened and fixed.

By adopting the structure, when the printing ink in the printing ink box 148 is used up and needs to be replaced, the printing ink box 148 and the protective cover 140 can be directly separated through the buckling part 149, so that the printing ink box 148 can be replaced conveniently.
