DETAILED DESCRIPTION
[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0023] Embodiment 1
[0024] like Figure 1As shown, in this embodiment, a display device of an intermittent motion mechanism simulating animal picking is mainly disclosed, including: a first carrier 1, which is provided with an object 2 for picking; the first carrier 1 is a ratchet; a first animal model 3, which includes at least one limb for picking, and the limb serves as a ratchet 4 to form a ratchet mechanism with the first carrier 1; specifically, in this embodiment, the first carrier 1 is an apple tree, the objects to be picked are apples, and the first animal model 3 is a mouse; of course, in other embodiments, the first carrier 1 can be a banana tree, and the first animal model 3 can be a monkey; it should be noted that both monkeys and mice have limbs, and the limbs are used to construct the ratchet 4.
[0025] like Figure 1 As shown, in this embodiment, the mouse includes a head 11, a body 8, and limbs; it should be noted that here, the limbs refer to the forelimbs, that is, "hands"; as for the hind limbs, that is, "legs" as the carrier of the first animal model 3, for the limbs, in this embodiment, the limbs are connected to the body 8 through the first driving disc 9, and the rotating shaft of the first driving disc 9 is fixed on the body 8. According to different materials, a pin fixing method or a bearing fixing method can be adopted, and the limbs are rotatably set on the first driving disc 9; along the vertical projection direction, the length of a tooth 10 on the first carrier 1 is less than the rotation point of the limb and the first driving disc The distance between the rotation axes of the disks 9 is less than the length of the two teeth 10 on the first carrier 1; for this point, it is necessary to explain in detail: according to the different overlapping areas of the limbs and the first carrier 1, the distance between the rotation point of the limbs and the rotation axis of the first driving disk 9 is variable, for example: when the limbs are located at the top of the ratchet, the length of one tooth 10 of the ratchet in the vertical projection direction is the longest, when the limbs are located on the left and right sides of the ratchet, the length of one tooth 10 of the ratchet in the vertical projection direction is the shortest. In any case, in this embodiment, the length is greater than one tooth 10 and less than two teeth 10; its movement process is as follows Figure 1 , 2, when the first driving disc 9 is rotated, the limb, that is, the pawl 4 will swing under the action of its own weight, so that Figure 1 The state movement is as follows Figure 2 state, swings to the height of one tooth 10, and then is blocked by the second tooth 10. If the first driving disc 9 continues to rotate, the pawl 4 will be driven to push the ratchet to move, thereby realizing the intermittent rotation of the ratchet. As the action is repeated, the "apple" on the ratchet will move to the vicinity of the mouse's limbs and be "picked".
[0026] In some embodiments, the non-return action of the ratchet mechanism can be achieved by the damping of the ratchet rotation itself. In this embodiment, a second animal model 7 is also provided, which includes at least one limb for non-return, and the limb serves as a non-return pawl 5. Specifically, the second animal model 7 is a mouse, and one of its limbs serves as a non-return pawl 5; the height of the second animal model 7 is lower than that of the first animal model 3; preferably, the contact points of the limbs of the two animal models with the ratchet are symmetrically arranged, and the non-return pawl 5 is connected to the body 8 of the second animal model 7 through an elastic member, and slides along the edge of the ratchet in unison under the action of the elastic member to achieve non-return; specifically, the elastic member can be a paddle or a torsion spring.
[0027] In this embodiment, a driving mechanism 6 is also provided to drive the limbs to move; further, the driving mechanism 6 is used to drive the first driving disc 9 to rotate. The general driving mechanism 6 is a handle 20 and a transmission mechanism. In this embodiment, the handle 20 is set away from the first driving disc 9 so that the movement of the first animal model 3 is fully displayed. Of course, this is not necessary; in addition, the transmission mechanism is not limited in any way. In this embodiment, if Figure 3 As shown, the transmission mechanism adopts a gear set. In some embodiments, it can be driven by a belt or a spur rack.
[0028] By using the limbs of the first animal model 3 as the pawl 4, the crown of the apple tree as the ratchet, and the limbs of the second animal model 7 as the non-return pawl 5, a detailed and effective display of the ratchet mechanism in the demonstration of a mouse picking apples is achieved, which is both entertaining and educational, so that the audience can learn the intermittent motion principle of the ratchet when seeing the process of the mouse picking apples.
[0029] Embodiment 2
[0030] like Figure 4 As shown, in this embodiment, a display device of an intermittent motion mechanism simulating animal picking is mainly disclosed, and its main structure is consistent with that in the first embodiment, except that, in this embodiment, the limbs of the first animal model 3 are directly connected to the rotating shaft of the ratchet. Specifically, the limbs are connected to the rotating shaft of the ratchet through a swing rod 18, and a driving mechanism 6 is used to drive the swing rod 18 to swing. In addition, the ratchet 4 and the swing rod 18 are connected by a torsion spring 19; Figure 4 As shown, when the rocker arm 18 swings clockwise, the ratchet does not rotate due to the presence of the non-return pawl 5, and the pawl 4 moves clockwise. Then, when the rocker arm 18 swings back counterclockwise, the pawl 4 drives the ratchet to rotate counterclockwise, and the non-return pawl 5 overcomes its own torsion spring 19 to achieve intermittent rotation of the ratchet.
[0031] In this working condition, the first animal model 3 can be a monkey, and the objects that can be picked are bananas; the swing rod 18 serves as the body 8 of the monkey, and the swing of the swing rod 18 means that the monkey is climbing on the banana tree.
[0032] Embodiment 3
[0033] like Figure 5 As shown, in this embodiment, the main structure is exactly the same as that of the first embodiment, and the action simulation of a mouse picking apples is also adopted. The difference is that in this embodiment, in order to make the device more vivid, the head 11 and the tail 12 of the mouse will swing as the picking progresses, which increases the fun.
[0034] Specifically, the first animal model 3 further includes: a head 11 and a tail 12 , the head 11 is hinged to the body 8 , and the tail 12 is hinged to the body 8 .
[0035] The transmission mechanism is provided with a second driving disc 22, and it rotates with the rotation of the transmission mechanism. If the transmission mechanism adopts a gear set, then the rotating shaft of one of the gears and the rotating shaft of the second driving disc 22 can be coaxially arranged; the tail 12 is movably connected to the non-center of the second driving disc 22 through the first connecting rod 13, and the movable connection here refers to the connection method of the hole matching pin; the end of the tail 12 is movably connected to the head 11 through the second connecting rod 14, and the line connecting the hinge point of the head 11 and the hinge point of the tail 12, the second connecting rod 14, the head 11, and the tail 12 constitute a four-bar linkage; its action process is that the second driving disc 22 drives the tail 12 to swing through the first connecting rod 13, and the tail 12 drives the head 11 to swing. While the whole process increases the fun, it directly shows the movement process of the four-bar linkage. Further, the length of the second connecting rod 14 is equal to the length of the line connecting the hinge point of the head 11 and the hinge point of the tail 12. At the same time, the two are arranged in parallel to construct a parallelogram.
[0036] In addition, in some embodiments, a different design is adopted for the driving mechanism 6 for swinging the mouse's tail 12. Specifically, take the second animal model 7 as an example; the second animal model 7 also includes: a second head, a second tail and a second body, the second head is hinged on the second body, and the second tail is hinged on the second body; the end of the second tail is movably connected to the second head through a third connecting rod 15, and the line connecting the hinge point of the second head and the hinge point of the second tail, the third connecting rod 15, the second head and the second tail constitute a four-bar linkage; the transmission mechanism includes a cam mechanism, wherein the cam 16 rotates with the rotation of the transmission mechanism, specifically, the rotating shaft of the cam 16 and a rotating shaft of the transmission mechanism are connected by a belt; the driven frame 17 performs reciprocating motion in the vertical direction, and the frame 21 is fixedly arranged; the driven frame 17 is used to abut the second tail of the second animal model 7; when the second tail of the second animal model 7 is not abutted, it swings counterclockwise due to its own weight, and when it is abutted, it swings clockwise, thereby realizing the swinging of the second tail and the second head of the second animal model 7.
[0037] Finally, it should be noted that, in the present invention, the first connecting rod 13, the second connecting rod 14 or the third connecting rod 15 that play a connecting role can be replaced by ropes.
[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
