Example 1
The present embodiment provides a pressing rotation device 100, which includes an outer cylinder 110 and a slider 120 that are engaged with each other, as shown with reference to fig. 1.
As shown in fig. 2 and 3, the outer cylinder 110 has a cylindrical shape and includes an inner surface 111, an outer surface 112, and first and second surfaces 113 and 114 disposed opposite to each other. The inner surface 111 of the outer barrel 110 is provided with a first slide rail 115 and a second slide rail 116. The first sliding rail 115 extends along the inner surface 111 from a position near the first surface 113 to the second surface 114 in a clockwise spiral manner. In contrast, the second slide rail 116 extends along the inner surface 111 in a counterclockwise spiral from a position near the second surface 114 toward the first surface 113. In this embodiment, the first sliding rail 115 and the second sliding rail 116 do not extend more than half the height of the outer cylinder 110 when they extend inward, so that the first sliding rail 115 and the second sliding rail 116 are in a non-intersecting state. Further, in the present embodiment, the first sliding rail 115 and the second sliding rail 116 are symmetrically disposed with a cross section of the outer cylinder 110 at half height as a symmetry plane.
As shown in fig. 2 and 4, the slider 120 includes a first slider 121 and a second slider 122. Wherein, the first sliding member 121 is slidingly engaged with the first sliding rail 115, and the second sliding member 122 is slidingly engaged with the second sliding rail 116. There are various ways of sliding fit, such as a pulley and rail fit, or a chute and slider fit. In the present embodiment, the first sliding rail 115 includes a pair of first sliding grooves (not labeled) disposed opposite to each other, and the first sliding member 121 is provided with a pair of first sliding blocks 1211 matching the pair of first sliding grooves, and the pair of first sliding blocks 1211 are slidably embedded in the pair of first sliding grooves, respectively. Similarly, the second sliding rail 116 includes a pair of second sliding grooves (not labeled) disposed opposite to each other, and the second sliding member 122 is provided with a pair of second sliding blocks 1221 matching the pair of second sliding grooves, and the pair of second sliding blocks 1221 are respectively slidably embedded in the pair of second sliding grooves. It should be noted that the arrangement of the two first sliding blocks 1211 and the two first sliding grooves is only one possible arrangement manner listed in this embodiment, and in other preferred embodiments of the present invention, the number of the first sliding blocks 1211 and the first sliding grooves may be single or greater than two, which may be set with reference to this embodiment. Similarly, the number of second sliders 1221 and second sliding grooves may be single or greater than two, and the number of second sliders 1221 is not necessarily the same as the number of first sliders 1211.
Further, the first slider 121 further has a first pressing surface 1212 disposed opposite to the first connecting surface 1214, and the second slider 122 further has a second pressing surface 1222 disposed opposite to the second connecting surface 1224. During the movement of the first slider 121 and the second slider 122, the first pressing surface 1212 is always located on the side of the first surface 113 away from the second surface 114, and the second pressing surface 1222 is always located on the side of the second surface 114 away from the first surface 113, that is, the first pressing surface 1212 and the second pressing surface 1222 are always located outside the outer cylinder 110, so that a user cannot be hindered by the outer cylinder 110 during the force application by the first pressing surface 1212 and the second pressing surface 1222.
In use, the pressing rotary device 100 according to the embodiment of the present invention applies force to bring the first slider 121 and the second slider 122 close by pinching the first pressing surface 1212 and the second pressing surface 1222. Since the first slider 121 and the second slider 122 are restricted from moving in the vertical direction during pressing, rotation does not occur. Therefore, the outer cylinder 110 is pressed in the horizontal direction in the process of approaching the first slider 121 and the second slider 122, and the outer cylinder 110 is driven to rotate. Specifically, when the first surface 113 is seen from the direction of the second surface 114, the first sliding groove extends clockwise in the direction of the second surface 114, and the first slider 1211 moves along the first sliding groove and presses the first sliding groove in the horizontal direction, so as to drive the outer cylinder 110 to rotate anticlockwise. Similarly, when the second surface 114 is seen from the direction of the first surface 113, the second sliding groove extends anticlockwise spirally towards the direction of the first surface 113, and the second sliding block 1221 moves along the second sliding groove and presses the first sliding groove in the horizontal direction, so as to drive the outer cylinder 110 to rotate clockwise. The counterclockwise rotation when seen from the first surface 113 to the second surface 114 is the same direction as the clockwise rotation when seen from the second surface 114 to the first surface 113, and the direction in which the first slider 121 and the second slider 122 press the outer cylinder 110 is the same, so that the outer cylinder 110 can be driven to rotate in a predetermined direction.
Further, the first slider 121 and the second slider 122 are connected by an elastic member 130, and in this embodiment, the elastic member 130 is a spring, and the spring is compressed during the pressing process of the first slider 121 and the second slider 122. The compressed spring will generate a resilient force to urge the first slider 121 and the second slider 122 away and back. The side of the first sliding member 121 facing the second sliding member 122 is concavely provided with a first accommodating groove 1213, and the bottom of the first accommodating groove 1213 is a first connecting surface 1214. Meanwhile, a second accommodating groove 1223 is concavely formed on a side of the second sliding member 122 facing the first sliding member 121, and a bottom of the second accommodating groove 1223 is a second connecting surface 1224. The two ends of the elastic member 130 are respectively located in the first accommodation groove 1213 and the second accommodation groove 1223, and connect the first connection surface 1214 and the second connection surface 1224.
Example 2
The present embodiment provides a pressing rotation device 200, which includes an outer cylinder 210 and a slider 220 that are engaged with each other, as shown with reference to fig. 5. In comparison with the pressing rotary apparatus 100 provided in embodiment 1, the pressing rotary apparatus 200 of the present embodiment has the following differences.
As shown in fig. 5 and 6, the outer cylinder 210 is cylindrical and includes an inner surface 211, an outer surface 212, and first and second oppositely disposed surfaces 213 and 214. The inner surface 211 of the outer barrel 210 is provided with a first slide rail 215 and a second slide rail 216. The first sliding rail 215 extends along the inner surface 211 from a position near the first surface 213 to the second surface 214 in a clockwise spiral manner. In contrast, the second rail 216 spirals counterclockwise along the inner surface 211 from a position proximate to the second surface 214 toward the first surface 213. In the present embodiment, the first sliding rail 215 and the second sliding rail 216 extend inward to a position close to the second surface 214, and the second sliding rail 215 and the second sliding rail 216 extend inward to a position close to the first surface 213, so as to increase the sliding distance between the first sliding member 221 and the second sliding member 222, and increase the force application time. Meanwhile, in order to keep the first slide rail 215 and the second slide rail 216 in a non-intersecting state, the first slide rail 215 and the second slide rail 216 in the present embodiment are staggered.
The slider 220 includes a first slider 221 and a second slider 222. Wherein, the first sliding member 221 is slidably engaged with the first sliding rail 215, and the second sliding member 222 is slidably engaged with the second sliding rail 216. In the present embodiment, the first sliding rail 215 includes a pair of first sliding grooves disposed opposite to each other, and the first sliding member 221 is provided with a pair of first sliding blocks 2211 matching with the pair of first sliding grooves, and the pair of first sliding blocks 2211 are respectively slidably embedded in the pair of first sliding grooves. Similarly, the second sliding rail 216 includes a pair of second sliding grooves disposed opposite to each other, and the second sliding member 222 is provided with a pair of second sliding blocks 2221 matching with the pair of second sliding grooves, and the pair of second sliding blocks 2221 are respectively slidably embedded in the pair of second sliding grooves.
The first sliding member 221 has a first connection surface 2214 facing the second sliding member 222, the second sliding member 222 has a second connection surface 2224 facing the first sliding member 221, and two ends of the elastic member 230 are respectively connected to the first connection surface 2214 and the second connection surface 2224.
Referring to fig. 5 and 7, since the moving distance of the first and second sliding members 221 and 222 in the present embodiment almost reaches the height of the outer cylinder 210, the first and second sliding members 221 and 222 are modified accordingly so that the first and second sliding members 221 and 222 do not interfere with each other. Specifically, the first connection surface 2214 is convexly provided with two first protruding blocks 2215, a first gap 2216 is formed between the two first protruding blocks 2215, similarly, the second connection surface 2224 is convexly provided with two second protruding blocks 2225, a second gap 2226 is formed between the two second protruding blocks 2225, projections of the first protruding blocks 2215 and the second protruding blocks 2225 on the cross section of the outer cylinder 210 are spliced into a circular ring, and projections of the elastic element 230 are located on the inner side of the circular ring. In the process of approaching the first sliding member 221 and the second sliding member 222, the two first protruding blocks 2215 are matched with the two second gaps 2226, and the two second protruding blocks 2225 are matched with the two first gaps 2216, so that the first protruding blocks 2215 and the second protruding blocks 2225 form a mutually staggered mode, and the purpose of not obstructing each other is achieved. Accordingly, the two first sliding portions are respectively located at one ends of the two first protruding blocks 2215 far from the first connection surface 2214, and the two second sliding portions are respectively located at one ends of the two second protruding blocks 2225 far from the second connection surface 2224.
Example 3
The present embodiment provides a fingertip gyroscope 10, referring to fig. 8, which includes a unidirectional bearing 310 and a pressing rotation device 100, the unidirectional bearing 310 is sleeved outside the pressing rotation device 100, and an inner ring 311 of the unidirectional bearing 310 is fixedly connected with an outer surface 112. The unidirectional bearing 310 is preferably a unidirectional needle bearing, and the unidirectional needle bearing has smaller resistance, so that the rotation time of the fingertip gyroscope 10 can last longer.
Further, the fingertip gyroscope 10 further comprises a plurality of load-carrying parts 320, wherein the load-carrying parts 320 are arranged along the radial direction of the unidirectional bearing 310 and are fixedly connected with the outer ring 312 of the unidirectional bearing 310, and the overall gravity center of the load-carrying parts 320 is located on the axis of the unidirectional bearing 310. In the present embodiment, there are two load carrying portions 320 in total, and the two load carrying portions 320 are symmetrically disposed on both sides of the one-way bearing 310. The weight 320 may increase the weight of the top outer race 312, increasing inertia, and allowing the top to spin longer. It should be noted that, unlike the gyroscope of the prior art, since the fingertip gyroscope 10 provided by the embodiment of the present invention can continuously power its rotation by pressing, the weight requirement on the load part 320 is not so strict, and even in the case of small weight, continuous rotation can be ensured.
As shown in fig. 2 and 8, when the fingertip gyroscope 10 is used, the first pressing surface 1212 and the second pressing surface 1222 are pinched when the fingertip gyroscope 10 is seen from the first surface 113 to the second surface 114, the first sliding member 121 and the second sliding member 122 are forced to approach each other, the outer cylinder 110 starts to rotate anticlockwise and drives the inner ring 311 of the unidirectional bearing 310 to rotate, the unidirectional bearing 310 is in a locked state, and the inner ring 311 drives the outer ring 312 to rotate synchronously. When the pressing is removed, the elastic member 130 pushes the first sliding member 121 and the second sliding member 122 away from each other, the outer cylinder 110 starts to rotate clockwise and drives the inner ring 311 of the one-way bearing 310 to rotate, and the one-way bearing 310 is in a non-locking state, so that the outer ring 312 still can keep idle. After the elastic member 130 returns the first slider 121 and the second slider 122 to the original position, the first pressing surface 1212 and the second pressing surface 1222 can be pressed again, so as to increase the power for the rotation of the fingertip gyroscope 10, and keep the fingertip gyroscope 10 in the rotated state all the time.
In summary, the present invention provides a pressing rotary device including an outer cylinder and a slider nested with each other. The inner surface of the outer cylinder is provided with a first sliding rail and a second sliding rail, the sliding piece comprises a first sliding piece in sliding fit with the first sliding rail and a second sliding piece in sliding fit with the second sliding rail, and the first sliding piece and the second sliding piece are connected through an elastic piece. When the first sliding piece and the second sliding piece are pressed to be close to each other, the outer cylinder starts to rotate around the axis of the outer cylinder through extrusion of the first sliding rail and the second sliding rail respectively. The pressing and rotating device is simple in structure and novel in design, and can convert the force in the axial direction of the outer cylinder into the power for rotating the outer cylinder.
Another object of the present invention is to provide a fingertip gyroscope, which includes the pressing rotation device of the one-way bearing, wherein an inner ring of the one-way bearing is fixedly connected with an outer surface of the outer cylinder. The finger tip gyroscope is ingenious in design and novel in structure, and can be operated by one hand. Through pressing the two ends of the pressing rotating device, the outer ring is enabled to rotate, the outer ring drives the one-way bearing, and the fingertip gyroscope can be rotated. And in the process of rotating the fingertip gyroscope, the fingertip gyroscope can be further increased in power by continuing to press, so that the fingertip gyroscope is kept to rotate continuously.
