Technical Field

[0001] This utility model relates to the field of decompression toy technology, specifically an EDC fingertip cracking decompression toy. Background Technology

[0002] In today's fast-paced life, multiple factors such as work pressure, academic burdens, and daily chores lead to increasing psychological stress, making the demand for stress-relief products increasingly urgent. Stress-relief toys, as tools that can help people release stress and alleviate anxiety, have received widespread attention, and their market size continues to expand.

[0003] There are many types of stress-relieving toys on the market, such as fidget spinners, squeeze toys, and stress balls. While these toys can meet people's stress-relieving needs to some extent, most suffer from limited functionality. For example, fidget spinners primarily relieve stress by generating visual and tactile stimulation through rotation, but their gameplay is relatively fixed and can easily become monotonous after prolonged use. Squeeze toys and stress balls mainly rely on squeezing and deformation to achieve stress relief, with simple interaction methods and a lack of diverse experiences. Existing stress-relieving toys also lack sufficient feedback. Many toys only provide tactile feedback during use, lacking multi-dimensional feedback such as sound and movement, failing to fully engage the user's senses and significantly reducing their stress-relieving effect. For instance, some tapping stress-relieving toys do not produce clear, pleasant sounds when tapped, failing to provide strong sensory stimulation and thus affecting their stress-relieving effect.

[0004] To address the aforementioned issues, this application proposes an EDC (Electronic Data Disposal) finger-smashing stress-relieving toy. Utility Model Content

[0005] The purpose of this invention is to provide an EDC (Electronic Data Disposal) fingertip cracking stress-relieving toy to solve the problem mentioned in the background art that the prior art can only provide single tactile feedback and lacks multi-dimensional feedback such as sound and movement.

[0028] Please see Figures 1-6This utility model provides a technical solution: an EDC (Everyday Carry) finger-smashing decompression toy, comprising a main shell 11 composed of two shell plates 111 arranged symmetrically front to back, a limiting component 12 installed inside the main shell 11, a decompression component A13 and a decompression component B14 installed on the main shell 11, an auxiliary locking mechanism 15 installed on one side of the limiting component 12, and a toggle component 16 installed on the main shell 11. When the thumb togglees the pressure handle 143, the locking block A153, driven by the pushing force of the sliding spring 157 and the second decompression spring 142, provides torque to the main arm 141, causing the limiting block 146 to fit tightly against the locking block A153. The locking block A153 then restricts the limiting block 146. In position, by turning the lever 162 to the left with the middle finger, the elastic force of the second decompression spring 142 causes the main arm 141 to quickly return to its original position. At the same time, the striking block 144 retracts the retaining shell 145 and strikes the clicker 17, making a sound, thus completing the play. To repeat the operation, by turning the lever 163 to the left with the middle finger, the slider B154 causes the locking block B156 to move to the left and separate from the locking head 133. The elastic force of the first decompression spring 132 causes the rotating block 131 to rotate, which in turn causes the spring block 134 to pop out and separate from the main shell 11. The spring block 134 moves away from the main shell 11 and the striking block 144. The spring block 134 is popped open, and then the spring block 134 is reset by the middle finger or the other hand, thus completing the play.

[0029] The limiting assembly 12 includes a top plate 121, a slide A122, and a slide B123. The top plate 121, slide A122, and slide B123 are fixedly connected between the two main housings 11. Slide A122 and slide B123 are located below the top plate 121, and slide A122 is located to the left of slide B123. The top plate 121 blocks the upper part of slider A151 and slider B154, slide A122 limits the bottom of slider A151, and slide B123 limits the bottom of slider B154, so as to facilitate the sliding of slider A151 and slider B154.

[0030] Decompression assembly A13 includes a rotating block 131, a first decompression spring 132, a locking head 133, and a spring block 134. The rotating block 131 is rotatably connected between the two main housings 11 via a rotating shaft. The first decompression spring 132 is fixedly connected between the rotating block 131 and one of the main housings 11. The locking head 133 is fixedly connected to the left end of the rotating block 131, and the spring block 134 is fixedly connected to the top end of the rotating block 131. Decompression assembly B14 includes a main arm 141, a second decompression spring 142, a pressure handle 143, a striking block 144, a stop shell 145, and a limiting block 14. 6. A main arm 141 is rotatably connected between two shell plates 111 via a pivot. A second decompression spring 142 is fixedly connected between one side of the main arm 141 and one of the shell plates 111. A pressure handle 143 is fixedly connected to the left side of the top of the main arm 141. A striking block 144 is fixedly connected to the right end of the main arm 141. A retaining shell 145 is fixedly connected between the two shell plates 111. A limit block 146 is fixedly connected to the right side of the bottom of the main arm 141. A mounting groove is provided on the left end of the spring block 134. A clicker 17 is fixedly connected to the inside of the mounting groove. The movement of the striking block 144... The trajectory is arc-shaped. The clicker 17 is positioned on the movement trajectory of the striking block 144. The middle finger can be used to flick the lever 162 outwards, causing the lever 163 to rotate to the left. The lever 163 causes the paddle block B155 to move to the left, which in turn causes the slider B154 to move to the left. The slider B154 then causes the locking block B156 to move to the left and separate from the locking head 133. The elastic force of the first decompression spring 132 causes the rotating block 131 to rotate, thereby causing the spring block 134 to pop out and separate from the main housing 11. The spring block 134 moves away from the main housing 11 and the striking block 144. Block 134 is popped open, and then the middle finger or the other hand is used to reset block 134 to complete the play. Repeat the operation. This is the second way to play. Block 134 rotates back, which drives block 131 to rotate back. Block 131 rotates back, which drives the locking head 133 to rotate back. The sliding spring 157 pushes the slider A151 and the locking block B156 to keep them away from each other. The arc surface of the locking head 133 contacts the locking block B156 and pushes the locking block B156 open. Then the sliding spring 157 resets the locking block B156, so that the locking head 133 is placed inside the slot B of the locking block B156.

[0031] The auxiliary locking mechanism 15 includes a slider A151, a toggle block A152, a locking block A153, a slider B154, a toggle block B155, a locking block B156, and a sliding spring 157. Slider A151 is slidably connected to the top of slide block A122. Toggle block A152 is fixedly connected to the right end of slider A151. The top of slider A151 is slidably connected to the top plate 121. Locking block A153 is fixedly connected to the top of slider A151. Slider B154 is slidably connected to the top of slide block B123. Toggle block B155 is fixedly connected to the left end of slider B154. Locking block B156 is fixedly connected to the top of slider B154. A sliding spring 157 is fixedly connected between locking block B156 and locking block A153. Toggle block B155 is located in front of toggle block A152. The movement trajectory of the limiting block 146 is arc-shaped, and the movement trajectory of the locking block A153 is straight. The movement trajectory of the limiting block 146 intersects with the movement trajectory of the locking block A153. A locking groove B is provided on the inner side of the locking block B156. The movement trajectory of the locking groove B of the locking block B156 is straight. The movement trajectory of the locking head 133 is arc-shaped, and the movement trajectory of the locking groove B intersects with the movement trajectory of the locking head 133. The actuating assembly 16 includes a turntable 161, a lever 162, and a lever 163. The front end of the shell plate 111 located at the front end is rotatably connected to the turntable 161 via a rotating shaft. The bottom end of the turntable 161 is fixedly connected to the lever 162. The inner side of the lever 162 is fixedly connected to the lever 163. A locking groove is provided on the front end of the shell plate 111 located at the front end. 3. The lever 163 is slidably connected to the inner side of the slot. The movement trajectory of the lever 163 is arc-shaped. The lever A152 and lever B155 are set on the movement trajectory of the lever 163. The index finger passes through the annular hole of the shell plate 111, the web of the thumb rests against the left side of the shell plate 111, and the middle finger is close to the lever 162. This is the normal grip posture of the toy. The thumb can be used to turn the pressure handle 143, which drives the main arm 141 to rotate to the left, so that the striking block 144 separates from the stop shell 145. Then the sliding spring 157 pushes the slider A151 and the locking block B156 to keep the slider A151 and slider B154 away from each other. After the main arm 141 rotates, it drives the limiting block 146 to rotate, and the locking block A153... The sliding spring 157 keeps the main arm 141 in contact with the main arm 141, and the second decompression spring 142 drives the main arm 141 to apply torque, causing the limiting block 146 to fit tightly with the locking block A153. The locking block A153 limits the limiting block 146, thereby maintaining the position of the main arm 141 after rotation and keeping the striking block 144 separated from the cover 145. First, the lever 162 can be turned to the left by the middle finger. The rotation of the lever 162 drives the turntable 161 to rotate, the turntable 161 drives the lever 162 to rotate, the lever 162 drives the lever 163 to rotate, the lever 163 rotates to the right, causing the lever A152 to slide to the right, the lever A152 drives the slider A151 to slide to the right, and the slider A151 slides to the right, causing the locking block A153 to slide to the right.This causes the locking block A153 to separate from the limiting block 146 on the main arm 141. Then, the elastic force of the second decompression spring 142 causes the main arm 141 to quickly return to its original position, which in turn causes the main arm 141 to drive the striking block 144 to return to its original position. Simultaneously, the striking block 144 retracts into the retaining shell 145 and strikes the clicker 17, producing a sound, thus completing the play. The operation can be repeated.

[0032] Working principle:

[0033] When playing with the toy, the index finger passes through the annular hole of the shell plate 111, the web of the thumb rests against the left side of the shell plate 111, and the middle finger is close to the lever 162. This is the normal grip posture for the toy. The thumb can be used to turn the pressure lever 143, causing the main arm 141 to rotate to the left, causing the striking block 144 to separate from the stop shell 145. Then, the sliding spring 157 pushes the slider A151 and the locking block B156 to keep slider A151 and slider B154 away from each other. After the main arm 141 rotates, it causes the limiting block 146 to rotate. The locking block A153 is kept in contact with the main arm 141 by the pushing force of the sliding spring 157, and the second decompression spring 142 drives the main arm 141 to apply torque, so that the limiting block 146 and the locking block A153 are tightly in contact. The locking block A153 limits the limiting block 146, thereby maintaining the position of the main arm 141 after rotation. To keep the striking block 144 separated from the cover 145, you can first turn the lever 162 to the left with your middle finger. The turn of the lever 162 will cause the turntable 161 to rotate, which in turn will cause the lever 162 to rotate. The lever 162 will then cause the lever 163 to rotate, which will cause the lever A152 to slide to the right. The lever A152 will then cause the slider A151 to slide to the right, which will cause the locking block A153 to slide to the right. This will cause the locking block A153 to separate from the limiting block 146 on the main arm 141. Then, the elastic force of the second decompression spring 142 will cause the main arm 141 to quickly return to its original position, which will cause the striking block 144 to return to its original position. As the striking block 144 retracts into the cover 145, it will strike the clicker 17 and make a sound, thus completing the play. Repeat the operation. This is the first way to play.

[0034] Alternatively, the lever 163 can be rotated to the left by flicking the lever 162 outward with the middle finger. The lever 163 causes the lever B155 to move to the left, which in turn causes the slider B154 to move to the left. The slider B154 causes the locking block B156 to move to the left and separate from the locking head 133. The elastic force of the first decompression spring 132 causes the rotating block 131 to rotate, which in turn causes the spring block 134 to pop out and separate from the main housing 11. The spring block 134 moves away from the main housing 11 and the striking block 144. The spring block 134 is popped away, and then the spring block 134 can be reset by operating the middle finger or the other hand to complete the play. Repeat the operation. This is the second way to play.

[0035] The spring block 134 rotates back, causing the rotating block 131 to rotate back. The rotating block 131 rotates back, causing the locking head 133 to rotate back. The sliding spring 157 pushes the slider A151 and the locking block B156 to keep them away from each other. The arc surface of the locking head 133 contacts the locking block B156 and pushes the locking block B156 away. After that, the sliding spring 157 resets the locking block B156, so that the locking head 133 is placed inside the slot B of the locking block B156.
