Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of weather humidity monitoring or teaching aids, specifically a pine cone change observation device. Background Technology
[0002] Pine cones, also known as pine pods or pine nuts, have high nutritional and medicinal value. They grow in clusters, mostly at the tips of branches, which are relatively high up.
[0003] Pine cone scales open in dry weather and close in humid weather. This is because the outer layer of pine cone scales consists of loosely arranged, stretchable cells, while the inner layer consists of tightly packed, stiff fibers. When the weather is humid, water molecules or tiny water droplets in the air condense on the scales, slide along the scales towards the center of the pine cone, accumulate at the stem, and are then drawn into the scales. The water fills the spaces between the cells, causing the stretchable outer layer to expand and extend, while the stiff inner layer remains taut. As a result, the scales gradually bend upwards until they close completely.
[0004] Currently, the education sector lacks observation devices that utilize pine cones to visually observe changes in air humidity and dryness. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a pine cone change observation device. Through the cooperation of the dial and the three-jaw clamping mechanism, the changes of pine cones in humid and dry environments can be observed intuitively, and it can also be determined whether the weather environment on that day is humid.
[0006] The purpose of this utility model is achieved through the following technical solution: a pine cone change observation device, the device comprising a three-jaw clamping mechanism and a rotatable scale, the three-jaw clamping mechanism comprising multiple elastic strips for clamping the pine cone, one of the elastic strips having a lug on its outer side, the scale having a hole on its edge, one end of a rope being looped onto the lug and the other end looped onto the hole in the scale, the movement of the elastic strip with the lug causing the scale to rotate, the scale having a pointer, and the rope being made of a rigid material. When the weather is humid, the pine cone closes, and multiple elastic strips converge towards the pine cone. The elastic strips with lugs pull the rope, causing the dial to rotate clockwise while the pointer remains stationary. Eventually, the pointer points to the "Wet" area on the dial. When the weather is dry, the pine cone's scales open outwards, pushing the multiple elastic strips to open. The rope then pushes the dial to rotate counterclockwise while the pointer remains stationary. Eventually, the pointer points to the "Dry" area on the dial.
[0007] It also includes a dial base, on which a first support is provided. The rotating shaft of the rotating handle passes through the upper part of the first support and is threadedly connected to the first support. The end of the rotating shaft is provided with a protrusion. One end of the second support is fitted onto the end of the rotating shaft, and the second support is provided with a groove that matches the protrusion. The other end of the second support is provided with a fixed shaft. The pointer and the dial are sequentially fitted onto the fixed shaft, and the pointer is fixed to the fixed shaft by a fixing member.
[0008] The pointer includes a pointer head and a right-angle bracket. The right-angle bracket includes a horizontal plate and a vertical plate. The pointer head and the vertical plate are located on opposite sides of the dial. The top of the pointer head and the top of the vertical plate are fixed by the horizontal plate. The bottom of the vertical plate is fitted onto a fixed shaft.
[0009] The fixing component is a spring. The middle part of the spring is sleeved on the fixed shaft and is located between the dial and the vertical plate. One end of the spring hooks the vertical plate and the other end hooks the dial, so as to prevent the pointer from moving without restricting the rotation of the dial.
[0010] The protrusion is cylindrical.
[0011] The three-jaw clamping mechanism also includes a circular base, with multiple elastic strips arranged at equal distances between adjacent elastic strips on the top edge of the circular base.
[0012] The circular base is ring-shaped. If the elastic strip cannot hold the pine cone, a pad that does not hinder the pine cone from absorbing moisture from the air can be placed in the middle of the circular base. This pad is used to prevent the pine cone from falling.
[0013] The elastic strip is made of an elastic material, or it can be made of other materials that can be bent under force.
[0014] It also includes a three-jaw clamping mechanism base, which includes a base plate and a circular seat. The circular seat is disposed on the base plate and is used to place and fix the circular base of the three-jaw clamping mechanism.
[0015] The beneficial effects of this utility model are: 1. This utility model, through the cooperation of a dial and a three-jaw clamping mechanism, allows for direct observation of the changes in pine cones under humid and dry environments, and also allows for determination of whether the weather environment on that day is humid.
[0016] 2. This invention can also increase students' interest in exploring the natural world by observing the changes in pine cones when they are damp and when they are dry. Attached Figure Description

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] In one embodiment of this application: like Figures 1 to 12 As shown, a pine cone change observation device includes a three-jaw clamping mechanism 1 and a rotatable dial 2. The three-jaw clamping mechanism 1 includes three elastic strips 11 for clamping the pine cone. One of the elastic strips 11 has a lug 12 on its outer side. The dial 2 has a hole on its edge. One end of a rope is looped on the lug 12 and the other end is looped on the hole in the dial 2. The rope is made of steel wire rope. The movement of the elastic strip 11 with the lug 12 can drive the dial 2 to rotate. The dial 2 is equipped with a pointer 21. Place the pine cone between the three elastic strips 11, securing it in place. At this point, the pine cone is dry, and pointer 21 indicates the "Dry" area on dial 2. When the weather is humid, water molecules or droplets in the air condense on the pine cone's scales, sliding along the scales towards the center of the cone, gathering at the stem, and then being absorbed into the scales. Water fills the spaces between the cells, causing the pine cone's elastic outer layer to expand and extend, while the rigid inner layer remains taut. As a result, the scales gradually bend upwards until they are completely closed. The closed pine cone resembles... Figure 10 As shown, due to the pine cone closing, the three elastic strips 11 will converge towards the pine cone. The elastic strips 11 with lugs 12 pull the steel wire rope through the lugs 12, and the steel wire rope pulls the dial 2 to rotate clockwise, while the pointer 21 remains stationary. Finally, the pointer 21 points to the "Wet" area on the dial 2. When the weather is dry, the scales of the pine cone open outwards, and the opened pine cone... Figure 11 As shown, the scales of the pine cone push the three elastic bars 11 to open outwards, the steel wire rope pushes the dial 2 to rotate counterclockwise, while the pointer 21 remains stationary. Finally, the pointer 21 points to the "Dry" area on the dial 2.
[0021] In the second embodiment of this application: Based on the previous embodiment, this embodiment improves the pine cone change observation device and further includes a dial base 3. A first support column 31 is provided on the dial base 3. The rotating shaft 33 of the rotating handle 32 passes through the upper part of the first support column 31 and is threadedly connected to the first support column 31. A protrusion 34 is provided at the end of the rotating shaft 33. One end of the second support column 35 is fitted onto the end of the rotating shaft 33, and the second support column 35 is provided with a groove that matches the protrusion 34. A fixed shaft 36 is provided at the other end of the second support column 35. The bottom of the pointer 21 and the center of the dial 2 are sequentially fitted onto the fixed shaft 36, and the pointer 21 is fixed to the fixed shaft 36 by a fastener.
[0022] The pointer 21 includes a pointer head 22 and a right-angle bracket 23. The right-angle bracket 23 includes a horizontal plate and a vertical plate. The pointer head 22 and the vertical plate are located on both sides of the dial 2, and the top of the pointer head 22 is fixed to the top of the vertical plate through the horizontal plate. The bottom of the vertical plate is fitted onto the fixed shaft 36.
[0023] Figure 3 In this design, the fixing component is a spring 37 or any other structure that can fix the pointer 21. The middle part of the spring 37 is sleeved on the fixed shaft 36 and is located between the scale 2 and the vertical plate. One end of the spring 37 hooks onto the front side of the vertical plate to prevent the vertical plate from tilting forward (or one end of the spring 37 can be hooked onto the back side of the vertical plate to prevent the vertical plate from tilting backward; which side to hook depends on the finished product, whichever side the vertical plate is more likely to tilt). The other end hooks onto the front side of the scale 2. The spring 37 is a torsion spring, which can withstand torsional deformation. While preventing the pointer 21 from moving, it does not affect the rotation of the scale 2. At this time, the rope can be a flexible soft rope. The spring 37 also has another function: to straighten the connection between the scale 2 and the three-jaw clamping mechanism 1 to ensure observation of the pine cone's changes. The torsion spring torque is less than the clamping force of the elastic strip 11 of the three-jaw clamping mechanism 1. First, place the dry pine cone between the upper parts of the three elastic strips 11 and clamp it. Then, adjust the position of the dial 2 so that the "Dry" area of the dial 2 is at the top. After adjusting it, adjust the position of the pointer 21 through the spring 37 so that the pointer 21 points to the "Dry" area. When the weather is humid, the pine cone closes, and the three elastic strips 11 will close towards the pine cone. The elastic strip 11 with the lug 12 pulls the flexible rope through the lug 12. The flexible rope pulls the dial 2 to rotate clockwise, while the pointer 21 remains stationary. Finally, the pointer 21 points to the "Wet" area on the dial 2.
[0024] Protrusion 34 is a cylinder.
[0025] The three-jaw gripping mechanism 1 also includes a circular base, and three elastic bars 11 are disposed on the top edge of the circular base, with adjacent elastic bars 11 arranged at equal distances.
[0026] The circular base is ring-shaped. If the upper part of the elastic strip 11 cannot hold the pine cone, a pad that does not hinder the pine cone from absorbing moisture from the air can be placed in the middle of the circular base. This pad is used to prevent the pine cone from falling.
[0027] The elastic strip 11 is made of an elastic material, or it can be made of other materials that can be bent under stress.
[0028] It also includes a three-jaw gripping mechanism base 4, which includes a base plate 41 and a circular seat 42, with the circular seat 42 mounted on the base plate 41. The circular base of the three-jaw gripping mechanism 1 is inserted into the circular seat 42. When the position of the dial 2 needs to be adjusted, the rotating handle 32 is turned. The rotating handle 32 drives the rotating shaft 33 to rotate, which in turn drives the protrusion 34 to rotate. The protrusion 34 drives the second support column 35 to rotate, which in turn drives the fixed shaft 36 to rotate. The fixed shaft 36 then drives the pointer 21 and the dial 2 to rotate upwards or downwards, thereby adjusting the dial 2 to be perpendicular to the ground. Figure 3 For example, when the handle 32 is turned clockwise, the dial 2 is lifted to the upper right, and when the handle 32 is turned counterclockwise, the dial 2 is lowered to the lower left.
[0029] In the third embodiment of this application: Based on the second embodiment, this embodiment improves the structure of the first pillar 31 and the second pillar 35 by removing the thread on the inner side of the top ring of the first pillar 31 and adding a cylinder at the bottom of the inner side of the top ring of the first pillar 31, with the upper left corner of the cylinder cut into a bevel, such as... Figure 13 As shown, the inner side of the bottom ring of the second pillar 35 is also changed from a groove to a horizontally placed triangular prism protrusion 6, as... Figure 14 As shown, the rotating handle 32 is provided with a first groove that mates with the cylindrical part of the first support column 31 that has a corner cut off, and a second groove that mates with the triangular prism protrusion 6 of the second support column 35, as shown. Figure 15 and Figure 16 As shown, the bottom of the first pillar 31 is movably connected to the dial base via the first universal ball 7. The bottom of the first pillar 31 is provided with a spherical groove for placing the first universal ball 7. A cylindrical pillar is welded to the bottom of the first universal ball 7, and the bottom of the cylindrical pillar is welded to the top of the dial base 3.
[0030] The top of the second support column 35 is provided with a spherical groove for placing or welding the second universal ball 5. A cylindrical support column is welded to the top of the second universal ball 5, and a U-shaped clamp is welded to the top of the cylindrical support column. The cylindrical end of the fixing handle 8 passes through one side of the U-shaped clamp. The fixing handle 8 is threadedly connected to the U-shaped clamp. The cylindrical end of the fixing handle 8 and the other side of the U-shaped clamp are used to clamp the fixing shaft 36. At this time, the fixing shaft 36 may not be welded to the top of the second support column 35 (that is, the fixing shaft 36 may be separated from the second support column 35 into two independent structures). When the fixed handle 8 is rotated clockwise, the fixed handle 8 and its cylindrical end move to the left relative to the U-shaped clamp. The cylindrical end of the fixed handle 8 and the U-shaped clamp clamp the fixed shaft 36 to prevent the fixed shaft 36 from falling off. When the fixed handle 8 is rotated counterclockwise, the fixed handle 8 and its cylindrical end move to the right relative to the U-shaped clamp. The cylindrical end of the fixed handle 8 and the U-shaped clamp loosen the fixed shaft 36, making it easier to remove the fixed shaft 36 and replace it with a new dial 2. The dial 2 can be made of paper.
[0031] like Figures 13-16 As shown, when the handle 32 is turned clockwise, the first support column 31 rotates to the right around the first gimbal 7, and simultaneously, the second support column 35 also rotates to the right around the bottom ring, thereby raising the scale 2. When the handle 32 is turned counterclockwise, the first support column 31 rotates to the left around the first gimbal 7, and simultaneously, the second support column 35 also rotates to the left around the bottom ring, thereby lowering the scale 2. The improvement in the third embodiment of this application is to make the pine cone change observation device look more aesthetically pleasing, while the improvement in the second embodiment of this application is more practical.
[0032] The above description is merely an embodiment of this utility model. It should be understood that this utility model is not limited to the form disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
