Description

Technical Field

[0001] The utility model specifically relates to a multi-position fixed clamping plate used for fish skin engraving. Background Art

[0002] There are three ways to make fish skin paintings: engraving, cutting and pasting, and sewing. Among them, engraving is relatively difficult. When the fish skin is processed, it goes through the steps of descaling, peeling, drying, pounding, and necessary bleaching to form a basic canvas for making fish skin paintings. In the process of engraving fish skin, it involves engraving a part of the edge and various positions of the fish skin to form a hollow pattern. Since the fish skin lacks a fixing tool that can correspond to the shape of the pattern during engraving, the difficulty of engraving fish skin increases. Due to the special material of fish skin itself, the current tightening and punching fixing method of ordinary canvas is difficult to directly apply to the specific operation of fish skin. There is a lack of a positioning method that can adapt to most fish skin shapes and can reduce damage to the fish skin. Utility Model Content

[0003] In order to overcome the defects of the prior art, a multi-position fixed clamping plate for fish skin engraving is provided to solve the above problems.

The fixed connecting strip is processed with a first strip sliding groove along its length direction, and a plurality of first connecting sleeves are slidably connected to the first strip sliding groove, and the plurality of first connecting sleeves are plugged and matched with a plurality of first plug posts, and each first plug post passes through the first connecting sleeve adjacent to it to press one side edge of the fish skin against an insertion area of ​​the bottom plate; the movable connecting strip is processed with a second strip sliding groove along its length direction, and a plurality of second connecting sleeves are slidably connected to the second strip sliding groove, and the plurality of second connecting sleeves are plugged and matched with a plurality of second plug posts, and each second plug post passes through the second connecting sleeve adjacent to it to press the other side edge of the fish skin against another insertion area of ​​the bottom plate, and a carved area for matching the fish skin is formed between the fixed connecting strip, the movable connecting strip and the bottom plate.

[0005] The beneficial effects of the utility model are:

[0006] The utility model forms a non-destructive positioning method for fish skin by the cooperation between the bottom plate, the fixed connecting strip, the movable connecting strip, a plurality of first connecting sleeves, a plurality of second connecting sleeves, a plurality of first plug posts and a plurality of second plug posts. The positional relationship between the fixed connecting strip, the movable connecting strip and the bottom plate is used to form a more consistent double-sided positioning method for the shape of the fish skin. The utility model can not only be used for the overall fixation of a whole piece of small-sized fish skin, but also for the partial fixation of a whole piece of large-sized fish skin. The fish skin is not damaged during the fixing process, and different positions of the fish skin can be changed in real time according to the specific engraving position and the pattern direction, which is conducive to improving the positioning effect of the fish skin and the engraving quality.

[0007] The utility model is a positioning method without punching holes, which is convenient for assisting the pressing operation of the parts without engraving patterns when engraving on the fish skin. The fish fillet is fixed at multiple points on both sides only by pressing and clamping, so that a stable fastening method of the peripheral parts is formed when the engraving knife cuts on the fish skin. The utility model is particularly suitable for the fastening and positioning process when a large area is hollowed out in fish skin painting. BRIEF DESCRIPTION OF THE DRAWINGS

Whether the fish skin is peeled off from one side or peeled off from both sides at the same time, the shape of the fish skin is generally in the form of a sheet with narrow ends at both ends and wide in the middle.

[0027] The shape and size of the fixed connecting strip 2 are the same as those of the dynamic connecting strip 3. The thickness of the fixed connecting strip 2 is thin, not exceeding 3 mm, in order to cooperate with the bottom plate 1 to form a clamping structure. Each end of the fixed connecting strip 2 is fixedly connected to the bottom plate 1 by at least one supporting thin column 21 to form a clamping structure in a fixed position.

The first insertion seam 10 is a penetration position on one side of the fish skin 30, and can also be used as an initial penetration position for a penetration method of the fish skin 30. The two ends of the dynamic connecting strip 3 are respectively slidably matched with the bottom plate 1, and the sliding direction of the dynamic connecting strip 3 is in the same direction as the width direction of the bottom plate 1. A second insertion seam 11 is formed between the bottom surface of the dynamic connecting strip 3 and the top surface of the bottom plate 1 to cooperate with the fish skin 30. The second insertion seam 11 is a penetration position on one side of the fish skin 30, and can also be used as an initial penetration position for another penetration method of the fish skin 30. The fixed connecting strip 2 is processed with a first strip-shaped sliding seam along its length direction. The movable groove 7, the shape of the first strip sliding groove 7 is matched with the shape of the fixed connecting strip 2, and a plurality of first connecting sleeves 4 are slidably connected to the first strip sliding groove 7. The first connecting sleeve 4 provides a multi-position dynamically changing insertion position for the subsequent positioning of the fish skin 30. A plurality of first connecting sleeves 4 are plugged into a plurality of first plug posts 6, and the first connecting sleeves 4 and the first plug posts 6 are not in a one-to-one correspondence. The number of the first plug posts 6 is less than or equal to the number of the first connecting sleeves 4. When the first plug posts 6 are configured to the maximum value, they are set in a one-to-one correspondence with the number of the first connecting sleeves 4 on the first strip sliding groove 7. According to specific positioning requirements, several first connecting sleeves 4 corresponding to the position area where the fish skin 30 needs to be fixed are selected to be penetrated with the first plug posts 6, that is, each of the several first connecting sleeves 4 corresponding to the position area where the fish skin 30 needs to be fixed is correspondingly penetrated with a first plug post 6, and each first plug post 6 passes through the first connecting sleeve 4 close to it to press the fish skin 30 tightly against the top surface of the bottom plate 1.

[0028] In the present embodiment, the movable connecting strip 3 is processed with a second strip sliding groove 8 along its length direction, and a plurality of second connecting sleeves 5 are slidably connected to the second strip sliding groove 8. The plurality of second connecting sleeves 5 are plugged into and matched with a plurality of second plug posts 9, and the second connecting sleeves 5 and the second plug posts 9 are not in a one-to-one correspondence. The number of second plug posts 9 is less than or equal to the number of second connecting sleeves 5. When the second plug posts 9 are configured to the maximum value, they are set in a one-to-one correspondence with the number of second connecting sleeves 5 on the second strip sliding groove 8. According to specific positioning requirements, several second connecting sleeves 5 corresponding to the position area where the fish skin 30 needs to be fixed are selected to be penetrated with second plug posts 9, that is, each of the several second connecting sleeves 5 corresponding to the position area where the fish skin 30 needs to be fixed is correspondingly penetrated with a second plug post 9, and each second plug post 9 passes through the second connecting sleeve 5 close to it to press the fish skin 30 against the top surface of the bottom plate 1. The fixed connecting strip 2, the movable connecting strip 3 and the bottom plate 1 enclose a carving area 20 for matching the fish skin 30, and the position of the fish skin 30 exposed in the carving area 20 is the position to be carved.

[0029] In the present embodiment, the top surfaces on both sides of the bottom plate 1 are respectively provided with plug-in areas, and there are several ways to form the plug-in areas. One way is to arrange a porous plate to form the plug-in area. The porous plate is a plate body made of elastic material, and a plurality of plug holes are arranged on the upper end thereof. The plug holes are matched with the outer diameter of the bottom end of the first plug column 6. The plug holes are elastic and can achieve radial micro-expansion, and cooperate with the first plug column 6 or the second plug column 9 to achieve the clamping effect of the fish skin.

The pressing sheet 16 is used to press on other parts of the fish skin 30 that have not been engraved or have been engraved, so as to provide stable circumferential support for the parts to be engraved or the parts being engraved, and to fix the position of the surrounding fish skin, and to provide favorable conditions for engraving the parts to be engraved or the parts being engraved.

[0038] Specific embodiment seven: This embodiment is a further limitation of specific embodiments three, four, five or six. The thickness of the pressing sheet 16 is the same as the thickness of the fixed connecting strip 2, and the thickness of the pressing sheet 16 is also the same as the movable connecting strip 3. The purpose is to provide a stable operating plane for the operator when the pressing sheet 16 is placed between the fixed connecting strip 2 and the movable connecting strip 3, so that the operator can apply pressure with his hand on the plane formed by the pressing sheet 16, the fixed connecting strip 2 and the movable connecting strip 3, thereby forming a uniform pressure fixation on the blocked part of the fish skin 30.

[0039] Specific implementation method eight: Combination Figures 1 to 13 To illustrate this embodiment, in this embodiment, the pressing sheet 16 is provided with a plurality of pressure strips 18, the bottom surface of each pressure strip 18 is pressed against the top surface of the pressing sheet 16 adjacent to it, and the two ends of each pressure strip 18 are detachably connected to the first connecting sleeve 4 and / or the second connecting sleeve 5 respectively.

[0040] In this embodiment, the pressure strip 18 is used to fix the pressing sheet 16. Multiple connecting holes 17 are processed at both ends of the pressure strip 18. The multiple connecting holes 17 are connected in sequence and arranged in sequence along the length direction of the pressure strip 18 to adapt to the first connecting sleeve 4 or the second connecting sleeve 5 at different positions.

[0041] In this embodiment, the pressure strip 18 has various structural forms and connection methods. Fig.12 and Fig.13As shown, one structural form of the pressing strip 18 is a straight strip. When the two ends of the pressing strip 18 are coaxial with the adjacent first connecting sleeve 4 or the second connecting sleeve 5 respectively, that is, a connecting hole 17 on one end of the pressing strip 18 is coaxially arranged with an adjacent first connecting sleeve 4 at this end, and the connection is realized through the insertion of a first insertion post 6. A connecting hole 17 on the other end of the pressing strip 18 is coaxially arranged with an adjacent second connecting sleeve 5 at this end, and the connection is realized through the insertion of a second insertion post 9.

[0042] Another structural form of the pressing strip 18 is a U-shaped strip. The two ends of the pressing strip 18 are respectively coaxially arranged with two first connecting sleeves 4 on the fixed connecting strip 2, so as to realize the continuous pressing effect in the length direction on the continuous part on the upper side of the fish skin 30 through the pressing piece 16. Similarly, another arrangement position of the pressing strip 18 is that the two ends of the pressing strip 18 are respectively coaxially arranged with two second connecting sleeves 5 on the movable connecting strip 3, so as to realize the continuous pressing effect in the length direction on the continuous part on the lower side of the fish skin 30 through the pressing piece 16.

[0043] The third structural form of the pressing strip 18 is a combined pressing strip, including a U-shaped strip and a straight strip. That is, a through hole is processed in the middle of the U-shaped strip along its thickness direction, and the straight strip passes through the through hole. The two cooperate to form a triangular support structure form, which is used for the pressing process of the triangular area of the pressing piece 16, so as to form a triangular shielding and fixing effect on the fish skin 30.

[0044] Furthermore, an arc-shaped notch 19 through which the pressing strip 18 can pass is also processed on the upper plate 4-1.
