Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sports auxiliary equipment, and particularly relates to a portable ground dotting device for orienteering. BACKGROUND

[0002] Orienteering is an outdoor competitive sport that combines physical and intellectual abilities. The core competitive logic is that athletes rely on maps and compasses to quickly locate and reach preset points in complex outdoor environments. The ground dotting device, as a key supporting equipment for this sport, plays a core role in confirming the arrival of athletes at the point, recording the check-in time, and standardizing the competition process. Whether it is a professional event or an amateur activity, the reliability and recognizability of the dotting device directly affect the fairness and smoothness of the competition. Athletes need to accurately find the dotting device of each point within a limited time to complete check-in. Therefore, whether the dotting device can be quickly identified in the outdoor environment is an important prerequisite for ensuring the efficiency of the competition and reflecting the competitiveness of the sport.

[0003] Currently, the ground dotting devices for orienteering on the market are mainly static identification structures, and they generally have the problem of not being easy to be quickly located by athletes in the outdoor environment. The core reasons are concentrated in three points: first, the interference of complex outdoor terrain, the device is often blocked by trees, shrubs, grass, leaves and other natural debris. It is difficult to stand out from the surrounding environment relying only on the appearance of the identification, and athletes need to spend a lot of time to investigate, which seriously affects the efficiency of travel; second, there is a lack of active prompting mechanism, and the existing devices mostly rely on visual search by athletes, without effective sound or dynamic prompt signals.

DETAILED DESCRIPTION

[0029] The specific embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0030] As Figures 1-8As shown, the present embodiment proposes a portable ground dotting device for orienteering, which comprises a mounting driving mechanism 1, an adjusting energy storage mechanism 2 and a knocking mechanism 3 fixedly connected inside the mounting driving mechanism 1, and a signal receiver 4 fixedly connected to the upper end of the mounting driving mechanism 1. The mounting driving mechanism 1 comprises a sleeve rod 11, a sliding rod one 12 clamped and connected to the inner upper part of the sleeve rod 11, a triangular wind driven cover 13 rotatably connected to the upper end of the sliding rod one 12, and a triangular driving frame 14 fixedly connected to the inner middle part of the triangular wind driven cover 13. The adjusting energy storage mechanism 2 comprises an adjusting assembly and an energy storage assembly. The adjusting assembly comprises a rotating seat 21, an inner tooth ring 22 fixedly connected to the lower end inside of the rotating seat 21, and a rotating cover 23 fixedly connected to the lower end outside of the rotating seat 21. The rotating cover 23 is uniformly distributed with inclined protrusions 24 on the lower end inside. The knocking mechanism 3 comprises a knocking assembly and an escapement assembly. The knocking assembly comprises a mounting plate 31, a sound emitting plate one 32 fixedly connected to the lower end right side of the mounting plate 31, a large knocking hammer 33 provided on the right side of the sound emitting plate one 32, a swing rod one 34 fixedly connected to the upper end of the large knocking hammer 33, two sound emitting plate twos 35 fixedly connected to the lower end left side of the mounting plate 31, and a small knocking hammer 36 provided between the two sound emitting plate twos 35 and fixedly connected to the upper end of the small knocking hammer 36.

[0031] In the embodiment, the lower end of the triangular wind driven cover 13 is rotatably connected to the middle lower part outside of the sleeve rod 11, the middle part of the triangular driving frame 14 is rotatably connected to the upper end outside of the sleeve rod 11, the upper end of the rotating seat 21 is fixedly connected to the lower end of the triangular driving frame 14, the middle part of the mounting plate 31 is fixedly connected to the middle lower part outside of the sleeve rod 11, the upper end of the swing rod one 34 is rotatably connected to the upper end right side of the mounting plate 31, and the upper end of the swing rod two 37 is rotatably connected to the upper end left side of the mounting plate 31.

[0032] Specifically, when there is wind, the wind blows the triangular wind driven cover 13 to rotate, which drives the rotating seat 21 to rotate through the triangular driving frame 14, thereby driving the rotating cover 23 to rotate. The inclined protrusions 24 uniformly distributed on the lower end of the rotating cover 23 constantly press the upper ends of the swing rod one 34 and the swing rod two 37, so that the swing rod one 34 and the swing rod two 37 constantly hit the sound emitting plate one 32 and the sound emitting plate two 35 through the large knocking hammer 33 and the small knocking hammer 36 at the lower end, generating impact sounds of different sizes. Through the cooperation of the mounting driving mechanism 1, the adjusting energy storage mechanism 2 and the knocking mechanism 3, the athletes can quickly find the dotting device to dot in the wild according to the impact sound, avoiding the athletes from being unable to quickly find the dotting device to dot due to the obstruction of trees and sundries in the wild. When the wind is strong, the triangular wind driven cover 13 rotates faster, and the athletes can judge the current wind force level according to the shape and rotating speed of the triangular wind driven cover 13, the size and intensity of the knocking sound, reasonably distribute physical fitness, and avoid the situation that the athletes cannot hear the impact sound from a distance due to the wind sound covering the impact sound when the wind is strong, thereby improving the competition results of the athletes.

[0034] In the embodiment, the lower end of the clamping seat 110 is fixedly connected with the upper end of the slide rod one 12, the upper end of the fixed seat 15 is fixedly connected with the lower end of the sleeve rod 11, and the upper end of the slide rod two 19 is slidably connected with the inner lower part of the sleeve rod 11.

[0035] Specifically, the supporting leg 16 at the lower end is opened, the dotting device is placed on the ground in the wild, in order to prevent it from falling, the protective cover at the lower end of the supporting leg 16 is opened, the connecting conical needle is inserted into the ground, and after the dotting device is fixed, the signal receiver 4 is placed on the upper end of the clamping seat 110.

[0036] In the embodiment, the energy storage assembly comprises a coil spring bin 25 and a sliding bin 212, the inside of the coil spring bin 25 is fixedly connected with a force storage coil spring 26, the inside of the force storage coil spring 26 is fixedly connected with a rotating ring 27, the lower end of the rotating ring 27 is fixedly connected with a gear one 28, the gear one 28 is meshingly connected with a transmission adjustment unit, the transmission adjustment unit is meshingly connected with a gear three 213, the lower end of the gear three 213 is connected with a gear four 214 through a rotating rod, the gear four 214 is meshingly connected with a gear five 215, and the upper end of the gear five 215 is connected with a gear six 216 through a rotating rod.

[0037] In the embodiment, the middle part of the coil spring bin 25 is fixedly connected with the middle part outside of the sleeve rod 11, the middle part inside of the rotating ring 27 is rotatably connected with the middle part outside of the sleeve rod 11, and the upper end of the gear three 213 and the gear six 216 are rotatably connected with the lower end right side of the coil spring bin 25 through rotating rods.

[0038] Specifically, the rotating seat 21 drives the gear six 216 to rotate through the meshing of the inner tooth ring 22 and the gear six 216, thereby driving the gear three 213 to rotate through the gear four 214, when the gear three 213 rotates, not only the gear two 29 is synchronously driven to rotate, but also the gear two 29 is pulled to mesh with the gear one 28, thereby driving the rotating ring 27 to rotate through the gear one 28, so that the force storage coil spring 26 stores energy.

[0039] In the embodiment, the adjusting unit comprises a gear two 29, the upper end of the gear two 29 is rotationally connected with a sliding seat 210, the front end of the sliding seat 210 is fixedly connected with a spring 211, the front end of the spring 211 is fixedly connected to the inner front side of a sliding bin 212, the gear two 29 is engaged with a gear three 213, and the upper end of the sliding bin 212 is fixedly connected to the lower end right side of the coil spring bin 25.

[0040] Specifically, when the force storage coil spring 26 cannot rotate to store energy, the gear two 29 cannot drive the gear one 28 to rotate to bounce, ensuring that the rotating seat 21 can continue to rotate, and the adjusting unit can disengage from the gear one 28 at the moment of rotation, not only realizing that the escapement mechanism in the knocking mechanism 3 can be smoothly started, but also protecting the device from overloading, while the triangular wind cover 13 can still rotate after the force storage coil spring 26 completes energy storage, so that the dot striking device can continuously emit knocking sound to guide the player to strike the dot.

[0041] In the embodiment, the escapement assembly comprises an escapement pawl 38, the escapement pawl 38 is engaged with an escapement wheel 39, the middle part of the escapement wheel 39 is fixedly connected with a driving shaft one 310, the front end of the driving shaft one 310 is fixedly connected with a driven bevel gear 311, the driven bevel gear 311 is engaged with a driving bevel gear 312, the middle part of the driving bevel gear 312 is fixedly connected with a driving shaft two 313, the middle upper part of the driving shaft two 313 is fixedly connected with a gear seven 314, the gear seven 314 is engaged with a gear eight 315, the upper end of the gear eight 315 is connected with a gear nine 316 through a rotating rod, the gear nine 316 is engaged with an internal tooth ratchet assembly 317, and the internal tooth ratchet assembly 317 is connected with a gear ten 318 through a rotating rod.

[0042] In the embodiment, the gear ten 318 is engaged with the gear one 28, the upper end of the driving shaft two 313 is rotationally connected to the lower end left side of the coil spring bin 25, and the upper ends of the gear nine 316 and the internal tooth ratchet assembly 317 are both rotationally connected to the lower end left side of the coil spring bin 25 through rotating rods.

[0043] In the embodiment, the rear left end of the escapement pawl 38 is fixedly connected to the front upper end of the swing rod two 37, and the middle parts of the driving shaft one 310 and the driving shaft two 313 are both rotationally connected to the upper end left side of the mounting plate 31.

[0044] Specifically, when the field wind is not enough to drive the triangular wind cover 13 to rotate, the force storage coil spring 26 rebounds, drives the escape pawl 38 to rotate through the rotating ring 27 and the gear one 28, drives the gear seven 314 to rotate through the gear nine 316 and the gear eight 315, drives the driven bevel gear 311 to rotate through the drive shaft two 313 and the drive bevel gear 312, drives the escape wheel 39 to rotate through the drive shaft one 310, and finally drives the swing lever two 37 to reciprocate through the escape pawl 38, so that the small knocking hammer 36 can continue to hit the sounding board two 35 to emit knocking sound in the windless state. Since the large knocking hammer 33 and the small knocking hammer 36 on both sides are designed to be of different sizes, the inclined protrusion 24 cannot fully press the swing lever one 34 to swing and rotate before the wind is not enough to drive the triangular wind cover 13 to rotate. When rotating, the inclined protrusion 24 on the left side can also make the swing lever two 37 initially swing due to the pressing of the inclined surfaces of the swing lever one 34 and the swing lever two 37. When rebounding, the spring 211 instantaneously pulls the sliding seat 210 to make the gear two 29 and the gear one 28 disengage, so that the force storage coil spring 26 starts to release energy, and then the escapement mechanism can be smoothly started. By adjusting the energy storage assembly in the energy storage mechanism 2 and the knocking mechanism 3, the energy is stored in the wind state, and then the knocking mechanism 3 can still emit knocking sound in the windless state. At the same time, the field is relatively quiet in the windless state, and the knocking mechanism 3 can only emit smaller knocking sound, avoiding the fact that two dotting devices emit larger knocking sound at the same time, which causes the athletes to misjudge the specific position of the dotting device. By designing the small knocking hammer 36 and the large knocking hammer 33 on both sides to be of different sizes, in addition to emitting knocking sound of different sizes in the field with large wind, so that the athletes can quickly find the dotting device, the small knocking hammer 36 can also press the inclined protrusion 24 to make the rotating cover 23 rotate.

[0045] It should be noted that the internal tooth ratchet assembly 317 adopts all the components in the spraying device for combined wardrobe production and the spraying method thereof disclosed in the publication No. CN120920250A Figure 8 The internal tooth ratchet assembly 317 adopts all the components in the spraying device for combined wardrobe production and the spraying method thereof disclosed in the publication No. CN120920250A The upper and lower ends of the triangular wind cover 13 are connected to the sleeve rod 11 of the slide rod one 12 by adopting similar components of the internal tooth ratchet assembly 317, i.e., the external gear is replaced by a toothless rotating ring, to keep the triangular wind cover 13 only rotating in one direction when the wind blows, so that the inclined protrusion 24 can only press the swing lever one 34 and the swing lever two 37 with the inclined side, Figures 2-3 The shape of the triangular wind cover 13 is used when the field wind is large. When it is known that the wind is small on the day of the competition, it can be replaced with Figure 1Another triangular wind driven cover 13 is used in the middle, the upper and lower triangular twist 15°-30°, the specific selection is according to the wind size of the day, the greater the twist angle, the better the wind collecting effect, but according to the principle of aerodynamics, the maximum twist is only 30°, and if it exceeds, the wind collecting effect will be reduced. Generally used in the field wind 1-4 level, when the field wind is greater than 4 level, the upper and lower vertical triangular wind driven cover 13 is used, the wind collecting effect is slightly inferior to the upper and lower twisted triangular wind driven cover 13, which ensures the low speed rotation of the triangular wind driven cover 13, plays the effect of protecting the device, and needs to be matched with the replacement of the large knocking hammer 33, the sound board one 32 and the sound board two 35 and the small knocking hammer 36, to ensure that the impact sound meets the wind level of the day, to avoid covering the impact sound when the wind sound is large, after installing the dotting device, the triangular wind driven cover 13 can be manually rotated to make the energy storage coil spring 26 preliminarily store energy, to avoid the situation that the dotting device cannot emit sound due to no wind after the triangular wind driven cover 13 is initially installed.

[0046] Working principle: when the dotting device is needed, first, open the support leg 16 at the lower end, place the dotting device on the ground in the wild, to prevent it from falling, open the protective cover at the lower end of the support leg 16, insert the cone needle into the ground, fix the dotting device, and then place the signal receiver 4 at the upper end of the card seat 110. When there is wind, the triangular wind driven cover 13 is blown by the wind to rotate, which drives the rotating seat 21 to rotate through the triangular drive frame 14, thereby driving the rotating cover 23 to rotate, and the oblique convex 24 on the lower end of the rotating cover 23 constantly extrudes the upper end of the swing lever one 34 and the swing lever two 37, so that the swing lever one 34 and the swing lever two 37 drive the large and small knocking hammers 33 and 36 at the lower end to constantly hit the sound emitting plates one and two 32 and 35, generating alternating impact sounds. Through the cooperation of the installation driving mechanism 1, the adjustment energy storage mechanism 2 and the knocking mechanism 3, the athletes can quickly find the dotting device for dotting in the wild according to the impact sound, avoiding the athletes from being unable to quickly find the dotting device for dotting due to the obstruction of trees and sundries in the wild. When the wind is strong, the triangular wind driven cover 13 rotates faster, and the athletes can judge the current wind force level according to the shape and rotating speed of the triangular wind driven cover 13, the size and density of the knocking sound, and reasonably allocate the physical fitness. When the wind is strong, the knocking sound is loud and dense, which can avoid the wind sound from covering the impact sound, causing the athletes to be unable to hear the impact sound from a distance, improving the competition results of the athletes. At the same time, the rotating seat 21 is engaged with the gear six 216 through the inner tooth ring 22 to drive the gear six 216 to rotate, thereby driving the gear three 213 to rotate through the gear four 214. When the gear three 213 rotates, it not only synchronously drives the gear two 29 to rotate, but also pulls the gear two 29 and the gear one 28 to engage, thereby driving the rotating ring 27 to rotate through the gear one 28, so that the energy storage coil spring 26 stores energy. When the energy storage coil spring 26 cannot rotate to store energy, the gear two 29 cannot drive the gear one 28 to rotate to jump, ensuring that the rotating seat 21 can continuously rotate. When the wind in the wild is not enough to drive the triangular wind driven cover 13 to rotate, the energy storage coil spring 26 rebounds, drives the pallet 38 to rotate through the rotating ring 27 and the gear one 28, thereby driving the gear seven 314 to rotate through the gear nine 316 and the gear eight 315, and further driving the driven bevel gear 311 to rotate through the drive shaft two 313 and the drive bevel gear 312, and finally driving the pallet 38 to reciprocating swing through the drive shaft one 310, thereby driving the small knocking hammer 36 to continue to hit the sound emitting plate two 35 to emit the impact sound in the windless state. Because the large and small knocking hammers 33 and 36 on both sides are designed to be different sizes, before the wind is not enough to drive the triangular wind driven cover 13 to rotate, the oblique convex 24 cannot fully extrude the swing lever one 34 to swing and rotate. When it rotates, the oblique convex 24 on the left side can also make the swing lever two 37 initially swing due to the extrusion of the oblique surfaces of the swing lever one 34 and the swing lever two 37. When it rebounds, the spring 211 instantaneously pulls the sliding seat 210 to make the gear two 29 and the gear one 28 disengage, so that the energy storage coil spring 26 starts to release energy.Further, the escapement mechanism can be started smoothly, and the energy storage assembly in the energy storage mechanism 2 and the striking mechanism 3 are matched to realize energy storage in the state of wind, so that the striking mechanism 3 can still emit the impact sound in the state of no wind. In the state of no wind, the field is relatively quiet, and the striking mechanism 3 can only emit a small impact sound, so as to avoid that the two dotting devices emit a large impact sound at the same time, and the athletes misjudge the specific position of the dotting device. The small striking hammer 36 and the large striking hammer 33 on the two sides are designed to be different in size, so that the athletes can quickly find the dotting device when the field has a large wind, and the small striking hammer 36 can press the inclined convex 24 to make the rotating cover 23 rotate, and the adjusting unit can be disengaged from the gear 1 at the moment of rotation. Not only can the escapement mechanism in the striking mechanism 3 be started smoothly, but also the device can be protected from overloading, and the triangular wind-driven cover 13 can still rotate after the energy storage of the power spring 26 is completed, so that the dotting device can continuously emit the impact sound to guide the athletes to dot.
