In a first aspect, the present utility model provides a pattern piece holder.

Fig. 1 is a schematic view of the external structure of a pattern piece clamp according to the present embodiment; fig. 2 is an exploded view of the pattern piece holder provided in the present embodiment. Referring to fig. 1 and 2, the axial direction of the pattern clip is X-direction, and the pattern clip includes a mounting wheel 100, a first elastic member 200, a retainer ring 300, and a pressing ring 400. The mounting wheel 100 has a mounting hole 101 penetrating the mounting wheel 100, and an annular support plate 102 is provided on a wall of one end of the mounting hole 101. The mounting hole 101 has a longitudinal direction and coincides with the X direction. Wherein the annular support plate 102 extends partially into the mounting hole 101 to support a pattern piece or an adapter clip 500 for clamping the pattern piece placed in the mounting hole 101. The annular support plate 102 does not entirely block the mounting hole 101 so that light can pass through the mounting hole 101 to radiate the shadow of the pattern piece located in the mounting hole 101.

The first elastic member 200 is mounted to the mounting wheel 100, and an orthographic projection of the mounting hole 101 in a length direction thereof overlaps an orthographic projection of the mounting hole 101 in the length direction of the mounting hole 101, so that the first elastic member 200 is at least partially located in the mounting hole 101. Alternatively, the first elastic member 200 may be mounted on the mounting wheel 100 by using an adhesive, a clamping connection, a mounting groove limitation, or a mechanical mounting method such as screw fastening. The first elastic member 200 may be a flexible spring, a torsion spring, a jump ring, a belleville spring, an elastic clamping strip, a shrapnel, a rubber block, or the like.

The limiting ring 300 is installed on the installation wheel 100, the limiting ring 300 and the annular supporting plate 102 are respectively located at two ends of the installation hole 101, namely, the limiting ring 300 and the annular supporting plate 102 are distributed at intervals along the length direction, and the inner diameter of the limiting ring 300 is smaller than the aperture of the installation hole 101. The press ring 400 can enter the mounting hole 101 through the limiting ring 300, and the press ring 400 is elastically clamped between the first elastic piece 200 and the hole wall of the mounting hole 101.

In this embodiment, when the pattern piece is installed, the pattern piece is first installed in the installation hole 101 and abuts against the annular support plate 102, the press ring 400 enters the installation hole 101 through the limiting ring 300, under the action of external force, one side of the press ring 400, which is close to the first elastic piece 200, abuts against and compresses the first elastic piece 200, one side of the press ring 400, which is far away from the first elastic piece 200, abuts against the hole wall of the installation hole 101, after the external force is removed, the first elastic piece 200 abuts against the press ring 400 and fixes the press ring 400, and the pattern piece is clamped and fixed between the annular support plate 102 and the press ring 400. When the pattern piece is detached, a user pushes the pattern piece and the press ring 400 from the side of the mounting hole 101 close to the annular support plate 102, so that the pattern piece and the press ring 400 are separated from the mounting hole 101. Therefore, the pattern piece disassembling and assembling operation is simple, the use is convenient, the technical problem that the existing pattern piece clamp is inconvenient to assemble and disassemble the pattern piece is solved, and the replacement efficiency of the pattern piece is improved.

In this embodiment, referring to fig. 2, the annular support plate 102, the pattern piece, the pressing ring 400 and the stop collar 300 are spaced apart in the X-direction. The thickness direction of the annular support plate 102, the thickness direction of the pattern piece, the axial direction of the press ring 400 and the axial direction of the retainer ring 300 are all identical to the X direction.

In this embodiment, the inner diameter of the stop collar 300 is smaller than the aperture of the mounting hole 101, so that the stop collar 300 partially protrudes from the mounting hole 101, and the compression ring 400 located in the mounting hole 101 is located between the stop collar 300 and the annular support plate 102 in the X-direction, and movement of the compression ring 400 in the X-direction is restricted.

In the present utility model, the outer diameter of the compression ring 400 may be larger than the inner diameter of the retainer ring 300. Because the compression ring 400 is annular, the compression ring can be elastically extruded and deformed, and can enter the mounting hole 101 through the limiting ring 300 after being elastically deformed, and then the compression ring is elastically restored. In this case, the compression ring 400 may be made of a rigid material, such as a steel ring, an aluminum ring, a copper ring, an iron ring, or a plastic ring, and the compression ring 400 may be made of an elastic material, such as a memory alloy ring, or a rubber ring.

In the present utility model, the outer diameter of the compression ring 400 may be equal to the inner diameter of the retainer ring 300. At this time, the pressure ring 400 may be elastically deformed into the mounting hole 101, or may be directly opposite to the inner diameter of the retainer ring 300 to be introduced into the mounting hole 101. In this case, the material of the press ring 400 may be a rigid material or an elastic material, and is not limited thereto. After the press ring 400 enters the mounting hole 101, the press ring 400 is pressed in the hole wall of the mounting hole 101 under the abutting of the first elastic piece 200 and is eccentrically arranged with the limiting ring 300, and the press ring 400 is positioned between the annular supporting plate 102 and the limiting ring 300 at the upper limit of X and cannot be separated from the mounting hole 101 from the inner diameter of the limiting ring 300 along the X direction.

In the present utility model, the outer diameter of the compression ring 400 may also be smaller than the inner diameter of the stop collar 300. At this time, the compression ring 400 may be elastically deformed into the mounting hole 101, or may be directly passed through the stopper ring 300 into the mounting hole 101 without elasticity. The material of the press ring 400 may be a rigid material or an elastic material, and is not limited herein. After the press ring 400 enters the mounting hole 101, the press ring 400 is pressed in the hole wall of the mounting hole 101 under the abutting of the first elastic piece 200 and is eccentrically arranged with the limiting ring 300, and the press ring 400 is positioned between the annular supporting plate 102 and the limiting ring 300 at the upper limit of X and cannot be separated from the mounting hole 101 from the inner diameter of the limiting ring 300 along the X direction.

Alternatively, the outer diameter of the compression ring 400 is 80% -120% of the inner diameter of the stop collar 300.

In one embodiment, referring to fig. 1 and 2, the pattern clip further includes an adapter clip 500, where the adapter clip 500 has an elastic clip for clamping the pattern clip, and the adapter clip 500 can enter the mounting hole 101 through the stop collar 300, and the adapter clip 500 is clamped between the annular support plate 102 and the press ring 400. When the size of the pattern piece is smaller, the annular support plate 102 cannot support the pattern piece, the pattern piece can be clamped on the transfer clamp 500, and the transfer clamp 500 abuts against the annular support plate 102 again, so that the pattern piece is fixedly mounted in the mounting hole 101.

In addition, the elastic clamping piece has certain elasticity, so that the elastic clamping piece can be compatible with pattern pieces with different thicknesses and different specifications, and has strong universality.

In this embodiment, the lamp irradiates the pattern piece during the use of the pattern piece fixture, so that the temperature of the pattern piece fixture is increased to 200-300 ℃, and the pressure ring 400 expands in size when heated. An expansion gap is reserved between the compression ring 400 and the hole wall of the mounting hole 101, and the first elastic piece 200 abuts against the compression ring 400, so that the expansion gap can be eliminated, and the compression ring 400 is stably arranged in the mounting hole 101.

In this embodiment, the first elastic member 200 may be in point contact, line contact or surface contact with the press ring 400. The press ring 400 may be provided with a positioning groove 401 or a positioning hole for accommodating a part of the structure of the first elastic member 200, so as to increase the contact area; the press ring 400 may also be provided with a supporting plane for contacting the first elastic member 200, where the first elastic member 200 may correspondingly be provided with a contact plane to be attached to the supporting plane, or may contact the supporting plane through an arc surface, a sharp corner, or an edge.

In some embodiments, referring to fig. 2 and 3, the outer sidewall of the compression ring 400 is provided with a detent 401. At least part of the first elastic piece 200 is matched with the positioning groove 401, so that the first elastic piece 200 can be embedded in the positioning groove 401, stable contact between the press ring 400 and the first elastic piece 200 is realized, and stable force transmission between the first elastic piece 200 and the press ring 400 is ensured.

In addition, the first elastic member 200 is partially adapted to the positioning groove 401, so as to define a moving distance of the press ring 400 in the X direction, and realize position stabilization of the press ring 400 in the axial direction.

Specifically, the positioning groove 401 extends along the circumferential direction of the press ring 400, the positioning groove 401 may be disposed around the circumference of the press ring 400, or may extend along the circumferential direction of the press ring 400 for a distance, and the radian of the positioning groove 401 may be pi/12-pi 4/3, which is not limited herein specifically.

Specifically, the number of the positioning grooves 401 is two or more, and the two or more positioning grooves 401 are arranged along the axial direction of the press ring 400. Because the position of the first elastic member 200 in the X direction is unchanged, the first elastic member 200 is clamped into the positioning groove 401 at different positions in the X direction, and then the position of the press ring 400 in the X direction is adjusted, that is, the size of the interval between the press ring 400 and the annular support plate 102 is adjusted, so that the assembly requirements of pattern pieces with different thicknesses and different specifications are compatible.

For example, when the first elastic member 200 is engaged with the positioning groove 401 closest to the annular support plate 102, the press ring 400 is spaced from the annular support plate 102 to the greatest extent, and a pattern piece having a large thickness can be assembled between the press ring 400 and the annular support plate 102. For another example, when the first elastic member 200 is engaged with the positioning groove 401 furthest from the annular support plate 102, the space between the press ring 400 and the annular support plate 102 is minimized, and a pattern piece having a smaller thickness can be assembled between the press ring 400 and the annular support plate 102.

Alternatively, the number of the positioning grooves 401 may be two, three, or more than three.

In one embodiment, referring to fig. 2 and 4, the end surface of the mounting wheel 100 remote from the annular support plate 102 is provided with a first mounting groove 103, and the mounting wheel 100 further has a notch 104 communicating with the middle of the first mounting groove 103 and the mounting hole 101. The first mounting groove 103 is located the terminal surface of installation wheel 100, makes things convenient for first elastic component 200 to install in first mounting groove 103, and stop collar 300 is fixed in the one side that annular support plate 102 was kept away from to installation wheel 100, and stop collar 300 and installation wheel 100 can the centre gripping fixed first elastic component 200, guarantees that the mounted position of first elastic component 200 is stable. The first elastic member 200 enters the mounting hole 101 through the notch 104 to abut against the compression ring 400 located in the mounting hole 101, so that the compression ring 400 is clamped in the mounting hole 101.

Specifically, referring to fig. 2, fig. 4 and fig. 5, the first elastic member 200 is an elastic clamping strip, and the elastic clamping strip includes a propping section 210 and two mounting sections 220, and the mounting sections 220 are nested in the first mounting groove 103, so that both ends of the first elastic member 200 are stably mounted in the first mounting groove 103. Two ends of the propping section 210 are respectively connected with two mounting sections 220, and the propping section 210 is at least partially positioned in the mounting hole 101 in a natural state and can prop against the compression ring 400 positioned in the mounting hole 101 to apply clamping force to the compression ring 400. Since the abutment section 210 is not retained in the first mounting groove 103, the abutment section 210 has an elastic displacement space capable of being pressed by the press ring 400 while reactively applying a clamping force to the press ring 400.

Specifically, the shape of the mounting section 220 is adapted to the shape of the first mounting groove 103, thereby ensuring that both ends of the first elastic member 200 are stably mounted in the first mounting groove 103. The shape adaptation means that the extending directions of the two are the same, but the extending lengths of the two can be equal or unequal. For example, when the first mounting groove 103 is of an arc shape, the mounting section 220 is also of an arc shape, and the curvatures of the mounting section 220 and the first mounting groove 103 are identical, and the mounting section 220 and the first mounting groove 103 are located on the same circle; when the first mounting groove 103 is wavy, the mounting section 220 is wavy, and the bending directions are consistent; when the first mounting groove 103 is linear, the mounting section 220 is also linear. Alternatively, the width of the mounting section 220 is approximately equal to the width of the first mounting groove 103 by a difference within ±20% of the width of the first mounting groove 103. Optionally, the length of the mounting section 220 is less than the length of the first mounting groove 103.

In one embodiment, the propping section 210 is attached to the press ring 400, so as to increase the contact area between the propping section 210 and the press ring 400 and improve the propping stability between the first elastic member 200 and the press ring 400. Specifically, the curvature of the abutment section 210 conforms to the outer sidewall curvature of the press ring 400, such that the abutment section 210 can conform to the press ring 400. Optionally, the outer peripheral wall of the compression ring 400 is provided with a positioning groove 401, and the shape of the abutment section 210 is adapted to the shape of the positioning groove 401, so as to fit into the groove wall of the positioning groove 401. For example, when the positioning groove 401 is of an arc shape, the abutting section 210 is of an arc shape, and the curvatures of the abutting section 210 and the positioning groove 401 are identical; when the positioning groove 401 is in a wave shape, the propping section 210 is also in a wave shape, and the bending directions are consistent; when the positioning groove 401 is linear, the abutment section 210 is also linear. In this embodiment, the width of the abutment section 210 is approximately equal to the width of the positioning groove 401, and the difference is within ±20% of the width of the positioning groove 401, i.e. the abutment section 210 may be embedded in the positioning groove 401 in an interference fit manner or may be embedded in the positioning groove 401 in a clearance fit manner. In this embodiment, the abutment section 210 is matched with the positioning slot 401, which does not mean that the lengths of the abutment section 210 and the positioning slot 401 are equal. The length of the abutment section 210 may be equal to the length of the positioning groove 401 or may be smaller than the length of the positioning groove 401. For example, the positioning groove 401 is disposed around the compression ring 400, and the length of the abutment section 210 is 1/10-1/5 of the length of the positioning groove 401.

The two ends of the propping section 210 are respectively connected with the mounting section 220 through the connecting section 230, namely, one end of the connecting section 230 is connected with the mounting section 220, and the other end of the connecting section 230 is connected with the propping section 210. In this embodiment, the abutting section 210 only translates during the abutting process with the press ring 400, so as to ensure stable contact between the first elastic member 200 and the press ring 400, and the connecting section 230 adapts to the translation of the abutting section 210 through bending rotation.

The mounting wheel 100 and the limiting ring 300 can be fixedly connected by adopting mechanical connection modes such as fastener connection, welding, bonding or clamping connection. For example, referring to fig. 1 and 2, the retainer ring 300 is detachably coupled to the mounting wheel 100 to facilitate maintenance of the first elastic member 200. For another example, the spacing ring 300 is not detachable from the mounting wheel 100, so that the first elastic member 200 is not detachably clamped between the spacing ring 300 and the mounting wheel 100, thereby ensuring that the position of the first elastic member 200 is stable and reliable, and the pressure ring 400 can be stably and reliably pressed.

In some embodiments, the outer peripheral wall of the limiting ring 300 is provided with a rotating gear tooth portion 310 so as to be capable of being meshed with the gear assembly 800, and the gear assembly 800 drives the pattern piece to rotate along with the rotation of the limiting ring 300, so that a light shadow with a rotating effect is manufactured.

It will be appreciated that in one embodiment, the outer peripheral wall of the mounting wheel 100 is provided with rotating gear teeth 310 so that the pattern piece rotates with the rotation of the mounting wheel 100; alternatively, the mounting wheel 100 or the limiting ring 300 is provided with a rotation hole, the cam mechanism is provided with a connecting rod, and the connecting rod is inserted into the rotation hole to drive the pattern piece clamp to rotate along with the rotation of the cam mechanism. In another embodiment, neither the mounting wheel 100 nor the stop collar 300 is provided with a rotating gear tooth 310 or a rotating hole, and the pattern piece holder may be provided without rotation.

In a second aspect, the present utility model provides a patterning device.

Specifically, the housing 600 includes an upper cover 610 and a bottom plate 620, and the upper cover 610 and the bottom plate 620 are fixedly connected to enclose the installation cavity.
