[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0030] Example 1: See Figures 1-8 As shown, a mechanical flower component includes a flower holder 1 and a petal component 2 rotatably mounted on the flower holder 1. A transmission component 3 is axially movable inside the flower holder 1. The transmission component 3 engages with the inner end of the petal component 2. When the transmission component 3 moves along the axial direction of the flower holder 1, it drives the petal component 2 to rotate around the flower holder 1, thereby realizing the opening and closing of the petal component 2.

[0031] The flower holder 1 is connected to a hollow tube 4 via a connector. A pull rod 5 is provided inside the hollow tube 4. The top of the pull rod 5 is connected to the transmission component 3. The top of the pull rod is fixedly connected to the center of the transmission component or tightly fitted. When the pull rod moves along the axial direction of the hollow tube, it can drive the transmission component to move synchronously. The pull rod should not move axially relative to the transmission component.

[0032] The connector includes a threaded sleeve 6, which is installed on the outer surface of the hollow tube 4, and an external thread 7 is provided on the outer surface of the threaded sleeve 6.

[0033] The inner surface of the flower holder 1 is provided with an internal thread 8 that is screwed into the external thread 7, and the flower holder 1 is screwed into the threaded sleeve 6.

[0034] In this embodiment, the up-and-down movement of the pull rod drives the transmission component to move up and down. Due to the up-and-down movement of the transmission component and the engagement between the petal component and the transmission component, when the transmission component moves along the axial direction of the flower base, it can push the petal component to rotate clockwise and counterclockwise around the flower base, thereby realizing the opening and closing of the petal component, that is, the opening and closing of the mechanical flower. This invention also provides a mechanical flower, including a housing 9 and the aforementioned mechanical flower components. There is at least one mechanical flower component. The hollow tube 4 is mounted on the housing 9. A drive unit 10 is provided inside the housing 9. The bottom of the pull rod 5 is connected to the drive unit 10. The drive unit 10 drives the pull rod 5 to reciprocate, and drives the transmission component 3 to reciprocate within the flower base 1.

[0035] After the mechanical flower component is assembled and connected with the driving part, if the pull rod is connected with the transmission member, and the position between the transmission member and the flower holder has some height deviation from the predetermined position, for example, when the driving part is in the initial position, the corresponding pull rod is at the bottom (of course, if the pull rod in the mechanical flower component is at the highest position, in this embodiment, the pull rod at the bottom in the initial position is taken as an example), under normal circumstances, the transmission member should be inside the flower holder and lower, and the petal piece is in the closed state. When the driving part drives the pull rod to move upward, it will push the outer end of the petal piece to rotate downward, so that the petal piece is opened. In the initial position, if the position of the transmission member deviates upward (is in the predetermined upper position) after the pull rod is connected with the transmission member, at this time, the outer end of the petal piece will be downward, that is, the petal piece is opened by a part, and when the subsequent driving member drives the pull rod to move upward and drives the transmission member to move upward, the outer end of the petal piece will rotate downward by a larger angle, that is, the petal piece is opened by a larger angle, and it cannot reach the preset state, resulting in poor appearance. When the driving part drives the pull rod to move downward and drives the transmission member to move to the lowest position, the petal piece is in a slightly open state and does not reach the preset closed state, resulting in poor appearance of the petal piece in opening and closing. Similarly, if the position of the transmission member deviates downward (is in the lower position of the predetermined position) in the initial position, the petal piece is closed too much (is larger than the predetermined closing angle), and when the transmission member moves to the highest position, the opening angle of the petal piece is small (is smaller than the predetermined opening angle), and the appearance is not good. Therefore, in this embodiment, the flower holder is directly connected with the hollow tube through the screw sleeve, and in the initial position, only the flower holder needs to be rotated. Since the flower holder is screwed with the screw sleeve, if the transmission member deviates upward in the initial position, the flower holder is rotated in one direction, so that the flower holder moves upward by a distance relative to the screw sleeve, that is, the transmission member moves downward relative to the flower holder, so that the flower holder is closed to the best position. If the transmission member deviates downward in the initial position, the flower holder is rotated in the other direction, so that the flower holder moves downward by a distance relative to the screw sleeve, that is, the transmission member moves upward relative to the flower holder, so that the flower holder is opened to the best position. When the subsequent driving part drives the pull rod to reciprocate and drives the transmission member to move upward and downward, it can stably and accurately drive the petal piece to rotate around the flower holder, so that the petal piece is opened and closed at the best angle. This adjustment method does not need to disassemble the mechanical flower component, only needs to rotate the flower holder by a certain angle, is convenient to adjust, ensures the appearance of the mechanical flower, and also reduces the assembly difficulty of the mechanical flower.

[0036] Referring to Figure 2 As shown in the figure, the internal thread 8 is arranged below the transmission member 3, the inner surface of the flower holder 1 is provided with an annular portion 11, the annular portion 11 is arranged between the transmission member 3 and the internal thread 8, and the screw sleeve 6 is arranged below the annular portion 11.

[0037] The inner diameter of the annular portion is smaller than the outer diameter of the screw sleeve, therefore, the annular portion can limit the relative moving distance of the receptacle and the screw sleeve, prevent the screw sleeve from moving too much upwards and completely entering into the receptacle (at this time, if the receptacle needs to be rotated, the screw sleeve cannot be gripped, which leads to the need to grip the hollow tube when the receptacle needs to be rotated, and the hollow tube may be twisted and damaged), when the receptacle rotates relative to the screw sleeve and moves downwards relative to the screw sleeve, if the annular portion abuts against the top of the screw sleeve, the receptacle cannot continue to rotate in this direction and move downwards relative to the screw sleeve, and the annular portion plays a limiting role.

[0038] Referring to Figure 2 、 6 , 7, the outer surface of the screw sleeve 6 is provided with a screw hole 12 perpendicular to the axis of the screw sleeve 6, the screw hole 12 is arranged below the receptacle 1, a fixing bolt 13 is screwed in the screw hole 12, the inner end of the fixing bolt 13 abuts against the outer surface of the hollow tube 4, and the fixing bolt 13 limits the screw sleeve 6 on the outer surface of the hollow tube 5.

[0039] The screw hole and the fixing bolt can connect the screw sleeve and the hollow tube, the screw sleeve is provided with a mounting hole matched with the hollow tube, the screw sleeve is sleeved on the hollow tube through the mounting hole to realize the connection of the screw sleeve and the hollow tube, in order to prevent the screw sleeve from moving axially and rotating circumferentially along the hollow tube, the screw hole and the fixing bolt are further arranged, the fixing bolt is screwed with the screw hole after the screw sleeve is mounted on the hollow tube, and the fixing bolt abuts against the outer surface of the hollow tube, so that the screw sleeve is limited on the hollow tube, the axial movement of the screw sleeve relative to the hollow tube is prevented, and the circumferential rotation of the screw sleeve relative to the hollow tube is also prevented. Since the receptacle is screwed with the screw sleeve, the axial movement and the circumferential rotation of the receptacle and the hollow tube are also limited.

[0040] Referring to Figure 2 、 6As shown in FIG. 7, the outer surface of the screw sleeve 6 is provided with an outer protrusion 14, which is arranged below the receptacle 1 and the outer surface of the screw hole 12 communicates with the outer surface of the outer protrusion 14. When the receptacle needs to be rotated, the outer protrusion also increases the friction force of the user's hand. The user holds the screw sleeve exposed below the receptacle with one hand and holds the receptacle with the other hand to rotate the receptacle. If the screw sleeve below is a cylindrical smooth surface (the outer thread is above the outer protrusion, and the outer surface of the screw sleeve below the outer protrusion is not provided with an outer thread, which is convenient for the user to hold the screw sleeve with his hand to position and rotate the receptacle, and also prevents the outer thread from scratching the user), the situation of slipping may occur. Therefore, the outer protrusion also increases the friction force and the gripping point to ensure that the hollow tube and the screw sleeve do not rotate with the receptacle when the receptacle needs to be rotated, preventing the hollow tube from being twisted and broken.

[0041] Referring to FIG. 7, the receptacle 1 is provided with a screw sleeve 6, and the screw sleeve 6 is arranged in the receptacle 1. Figure 6 、 7 As shown in FIG. 7, the receptacle 1 is provided with a screw sleeve 6, and the screw sleeve 6 is arranged in the receptacle 1.

[0042] In this embodiment, during the opening and closing process of the petal member, the driving part drives the pull rod and the transmission member to move, and the petal member also rotates around the receptacle. Therefore, the receptacle, the screw sleeve, and the hollow tube will all be vibrated. Since the receptacle and the screw sleeve are screwed, the vibration may cause the receptacle to rotate relative to the screw sleeve, which in turn causes the opening and closing degree of the petal member to change. Therefore, a damping member is also provided to prevent the vibration during the operation of the mechanical flower from causing the receptacle to rotate relative to the screw sleeve.

[0043] Preferably, the damping member is an elastic ring, which is arranged in the thread groove formed by the outer thread. More preferably, the damping member is a high-quality environmentally friendly fatigue-resistant and oxidation-resistant modified silica gel ring, thereby preventing the receptacle from rotating relative to the screw sleeve during the operation of the mechanical flower.

[0044] The receptacle 1 is provided with a first cavity 16, and the transmission member 3 is slidingly arranged in the first cavity 16. The inner thread 8 and the annular part 11 are arranged below the transmission member 3 in the first cavity 16.

[0045] The pull rod 5 is a soft pull rod. In this way, even if the hollow tube has a curvature, it does not affect the assembly of the pull rod into the hollow tube.

[0046] In the embodiment, the driving part 10 comprises a motor 17 and a cylindrical cam 18, the cylindrical cam 18 is installed on the output shaft of the motor 17, the output shaft of the top of the motor 17 is connected with the middle part of the bottom surface of the cylindrical cam 18, the motor 17 is configured to drive the cylindrical cam 18 to rotate, when the output shaft of the motor 17 rotates, the cylindrical cam 18 is driven to rotate;

[0047] The outer surface of the cylindrical cam 18 is provided with a cam groove 19, one end of each of the pull rods 5 is connected with the transmission member 3 of the corresponding mechanical flower part through a hollow pipe 4, the other end of the pull rod 5 is provided with a fixing ring 20, the side part of the fixing ring 20 is inserted into the cam groove 19.

[0048] The end of the pull rod of the fixing ring end is arranged beside the cylindrical cam, when the cylindrical cam rotates, the pull rod is driven to move reciprocatingly along the hollow pipe through the cam groove and the fixing ring, and the transmission member is driven to move reciprocatingly along the receptacle shaft, wherein the upper surface of the shell is provided with a control switch for controlling the operation of the motor.

[0049] In the utility model, the two sides of the cam groove have height difference, the two sides with height difference are connected through arc grooves, that is, the cam grooves have different heights at different positions, so that when the motor drives the cylindrical cam to rotate, the cam grooves at different height positions pull or push the height of the fixing ring to change, when the height of the fixing ring changes, the pull rod is also pulled or pushed to move axially along the hollow pipe, so that the axial movement of the transmission member is realized, and the opening and closing of the petal member is driven.

[0050] In the utility model, the outer surface of the pull rod contacts the inner surface of the hollow pipe, or there is a micro gap (the gap is very small, and the pull rod cannot bend or deform in the hollow pipe) between the outer surface of the pull rod and the inner surface of the hollow pipe, so that the pull rod can move together with the fixed ring when the height of the fixed ring changes. If the inner diameter of the hollow pipe is greater than the outer diameter of the pull rod, when the fixed ring is driven by the cam groove to move downward, the pull rod can be pulled downward by the fixed ring to move downward, so that the transmission member moves downward to drive the petal assembly to perform a closing action. When the fixed ring is driven by the cam groove to move upward, the pull rod deforms and bends in the hollow pipe because the outer diameter of the pull rod is smaller than the inner diameter of the hollow pipe, so that the transmission member cannot be lifted (moved upward), and the petal assembly cannot be opened. Therefore, the outer surface of the pull rod contacts the inner surface of the hollow pipe or has a micro gap, so that the pull rod cannot deform in the hollow pipe and can only move upward, so that the transmission member is lifted synchronously to drive the petal assembly to open. The shell has a cavity 11, the cylindrical cam is in the cavity, and the outer edge of the fixed ring is arranged close to the inner wall of the cavity or the outer surface of the fixed ring contacts the outer surface of the cavity, so that the fixed ring does not separate from the cam groove when the cylindrical cam rotates, and the cylindrical cam always drives the pull rod to move upward and downward when the cylindrical cam rotates.

[0051] Meanwhile, the mechanical flower can be provided with one set of mechanical flower components or a plurality of sets of mechanical flower components, and the actual situation is selected or installed, and the pull rod at the bottom of the corresponding mechanical flower component is connected with the driving part, the pull rod of all the mechanical flower components can be driven to move simultaneously through the working of the driving part, and the petals of all the mechanical flower components can be opened and closed.

[0052] In the utility model, the hollow pipe can be a straight pipe or a pipe with an arc, so that the pull rod can also drive the transmission member to move along the petal shaft, and the mechanical flower is more beautiful. Preferably, the pull rod is a metal pull rod.

[0053] Of course, the driving part can also be a jacking mechanism, such as a jacking motor and a jacking plate, the bottom of the pull rod is connected with the jacking plate, and the jacking plate is driven by the jacking motor to move upward and downward, so that the plurality of pull rods are driven to reciprocate simultaneously through the upward and downward movement of the jacking plate. Or the driving part can also be other structures, which can drive all the pull rods to reciprocate.

By moving the transmission piece along the axial direction of the receptacle, the annular convex tooth and the inner end clamping groove are meshed, the petal is pushed through the rotation of the side clamping groove and the annular part, and the outer end of the petal is rotated upward or downward, so that the opening and closing of the petal is realized.

[0055] The petal piece can be one layer, i.e. a single-layer mechanical flower structure, or two layers, i.e. a double-layer mechanical flower structure. Of course, it can also be three layers, four layers, five layers or even more layers. Each layer of petal piece is arranged along the axial direction of the receptacle, and the transmission piece has an annular tooth corresponding to the petal piece.
