Description

Technical Field

[0001] This invention relates to the field of referee equipment technology, specifically to a field event referee's chair and flag lifting device with a linkage warning mechanism. Background Technology

[0002] A field event referee chair and flag raising device with a linkage warning mechanism is an integrated referee equipment for field events. It integrates a referee chair, an automatic flag raising structure and a linkage warning mechanism. The referee can control the smooth raising and lowering of the flag for valid and foul judgments as soon as he sits down, without having to hold and wave the flag, reducing operational errors. The linkage warning can simultaneously alert athletes on the field, recorders and remote referees with sound and light. The chair is suitable for field event placement, the raising mechanism prevents flag tangling, simplifies the single-person refereeing process, unifies the visual signals for judgment, improves the efficiency of judgment transmission, and maintains order on the field. It is suitable for use in various field events such as long jump and shot put. Typically, field event referee chairs and flag-raising devices with linked warning mechanisms are activated by pressing a button during adjudication. The raising device then uses a motor to rotate the coaxial flag, thus raising or lowering the flag. However, existing referee chair flag-raising devices rely solely on a motor to raise or lower the flag vertically, resulting in a limited range of motion. This makes it difficult for athletes and referees at a distance to quickly detect warning signals, further reducing the warning capability of the flag-raising device when in motion. Summary of the Invention

[0003] The purpose of this invention is to provide a flag lifting device for a field event referee's chair with a linkage warning mechanism, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a flag raising device for a field event referee's chair with a linkage warning mechanism, comprising a chair and further comprising: The fixing component is located at the bottom of the seat and is used to provide support for the seat.

[0005] Furthermore, the fixing components include several support columns fixedly connected to the side wall of the main body; Several support columns are symmetrically distributed around the seat, and baffles are fixedly connected to the side walls of the support columns; Several support columns are fixedly connected to several foot rods, and the foot rods are evenly distributed with baffles. There are two support columns and baffles. The support columns provide support for the seat, and the baffles enhance the support force of the support columns.

[0006] Furthermore, a flag raising device for a field event judge's chair with a linkage warning mechanism is applicable to a field event judge's chair with a linkage warning mechanism. It includes several main bodies fixedly connected to the side wall of a motor, the main bodies being symmetrically distributed around the chair as a center, and a flag being provided at the bottom of each main body. It also includes: A rotating mechanism, installed inside the main body, is used to swing and open the flag.

[0007] Furthermore, the main body includes: The flag-raising assembly, located on the side wall of the main body, provides power for raising the flag.

[0008] Furthermore, the rotating mechanism includes: A shaking component is installed on the side wall of the flag-raising component; The swing component is located on the side wall of the swing component; A toggle component, located at the bottom of the shaking component, is used to push the flag to unfold and reset.

[0009] Furthermore, the flag-raising assembly includes a motor fixedly connected to the side wall of the main body, and an output shaft is fixedly connected to the side of the motor closer to the main body; The output shaft rotates through the body.

[0010] Furthermore, the wobbling assembly includes a sliding ring slidably connected to the side wall of the output shaft, and a fixing rod is fixedly connected to the bottom of the sliding ring; The fixing rod slides through to the outside of the main body, and an S-groove is opened on the side wall of the main body; Several arc-shaped pieces are fixedly connected to the side wall of the sliding ring, and the arc-shaped pieces are symmetrically distributed around the sliding ring. There are two curved plates, and the movement of the curved plates reduces the possibility of the sliding ring getting stuck when sliding.

[0011] Furthermore, the swing-off assembly includes a sliding cylinder slidably connected to the bottom of the fixed rod, and a contact ball is fixedly connected to one end of the sliding cylinder near the side wall of the main body; Several springs are fixedly connected to the side of the contact ball near the sliding ring, and the springs are symmetrically distributed with the sliding ring as the center. The end of the spring furthest from the contact ball is fixedly connected to the side wall of the sliding ring; The sliding cylinder slides through to the outside of the S-groove, and a flag is rotatably connected to the outer surface of the part of the sliding cylinder that extends out of the main body side wall. Two springs are provided to ensure the stability of the contact ball's contact with the inner wall of the main body when the contact ball rotates.

[0012] Furthermore, a ball bearing is provided at the end of the spring away from the contact ball, and the ball bearing is rotatably connected to the arc-shaped plate.

[0013] Furthermore, the actuating assembly includes a rotating disk rotatably connected to the end of the contact ball away from the sliding ring, and a number of actuating plates are fixedly connected to the side wall of the rotating disk, the number of actuating plates being symmetrically distributed around the sliding cylinder. Several rubber sheets are fixedly connected to the side wall of the rotating disk, and the rubber sheets are distributed circumferentially around the contact ball; The rubber sheet is initially in contact with the baffle.

[0014] The present invention has the following beneficial effects: 1. In this invention, the sliding ring drives the sliding cylinder to rotate via the fixed rod. The rotation of the sliding cylinder causes the flag to rotate synchronously. Since the sliding cylinder is in contact with the side wall of the S-groove, when the sliding cylinder is driven to rotate by the fixed rod, it will swing left and right under the guidance of the arc of the S-groove. The swing of the sliding cylinder will cause the sliding ring to slide on the output shaft. At the same time, the motor is constantly rotating, and the sliding cylinder will continuously move upward when it swings. This reduces the situation where the movement mode of the fixed rod is too monotonous and the warning effect is insufficient, thereby further improving the warning capability of the flag lifting device of the field judge's seat during movement.

[0015] 2. In this invention, after the spring is compressed to a certain distance, the continued compression of the spring will cause the contact ball to rotate. The contact ball will cause the sliding cylinder to rotate synchronously. The rotation of the sliding cylinder will cause the flag that is curled up at the bottom to rotate until the flag is fully opened. When the sliding cylinder returns to its original position, the compressed spring will gradually rebound, and the sliding cylinder will rotate in the opposite direction, thereby retracting the unfolded flag. This reduces the swaying of the flag due to external factors such as wind when the flag is not raised, which may cause the competitors to be distracted. This further improves the stability of the flag raising device of the field event referee's seat.

[0016] 3. In this invention, when the sliding ring tilts slightly, it may cause jamming when sliding on the output shaft. When the sliding ring rotates, the arc-shaped piece will contact the inner wall of the main body and deform. When the arc-shaped piece rotates to a certain angle, the ball bearing will contact the inner wall of the main body to ensure the normal rotation of the sliding ring. The deformation of the arc-shaped piece will push the sliding ring to fit tightly against the output shaft. When the sliding ring slides, the pushing of the arc-shaped piece reduces the tilting of the sliding ring. At the same time, the ball bearing ensures the smoothness of the sliding ring's movement, further improving the smoothness of the flag lifting device of the field judge's chair during movement.

[0017] 4. In this invention, when the rotating disk rises with the sliding cylinder, the rotation direction of the rotating disk is opposite to the rotation direction of the sliding cylinder when it slides. When the rotating disk rotates, it will drive the actuating plate to rotate synchronously. When the actuating plate moves, it will actuate the edge of the flag. When the edge of the flag is lifted by the actuating plate, the actuating plate will enter the inside of the curled flag and gradually open the curled flag. This reduces the situation where the curled flag is fluffy but not fully opened when the sliding cylinder rotates to the middle of the main body and begins to rotate. This further improves the integrity of the flag opening of the flag lifting device of the field judge's seat.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-8 As shown, the present invention is a flag raising device for a field event referee's chair with a linkage warning mechanism, including a chair 3, and further comprising: The fixing component 31 is disposed at the bottom of the seat 3 and is used to provide support for the seat 3.

[0024] The fixing component 31 includes a plurality of support columns 311 fixedly connected to the side wall of the main body 1; Several support columns 311 are symmetrically distributed around the seat 3, and baffles 312 are fixedly connected to the side walls of the support columns 311. A number of foot rods 313 are fixedly connected between a number of support columns 311, and the foot rods 313 are evenly distributed with baffles 312. There are two support columns 311 and baffles 312. The support column 311 provides support for the seat 3, and the baffle 312 increases the support force of the support column 311.

[0025] A flag raising device for a field event judge's chair with a linkage warning mechanism, applicable to a field event judge's chair with a linkage warning mechanism, includes several main bodies 1 fixedly connected to the side wall of a motor 111, the several main bodies 1 being symmetrically distributed around the seat 3, a flag 4 being provided at the bottom of the main body 1, and further includes: Rotating mechanism 2 is installed inside the main body 1 and is used to swing and open flag 4.

[0026] Entity 1 includes: The flag-raising assembly 11 is located on the side wall of the main body 1 and is used to provide power for raising the flag 4.

[0027] Rotating mechanism 2 includes: A shaking component 21 is disposed on the side wall of the flag-raising component 11; The swing component 22 is disposed on the side wall of the shaking component 21; A toggle component 23 is located at the bottom of the shaking component 21. The toggle component 23 is used to push the flag 4 to unfold and reset.

[0028] The flag-raising assembly 11 includes a motor 111 fixedly connected to the side wall of the main body 1, and an output shaft 112 fixedly connected to the side of the motor 111 near the main body 1. The output shaft 112 rotates through the body 1, and the motor 111 drives the flag 4 to rise gradually from the bottom through the rotation of the output shaft 112 to warn the participants, thereby raising and lowering the flag 4 on the side wall of the referee's chair.

[0029] The wobbling assembly 21 includes a sliding ring 211 that is slidably connected to the side wall of the output shaft 112, and a fixing rod 212 is fixedly connected to the bottom of the sliding ring 211; The fixing rod 212 slides through to the outside of the main body 1, and the side wall of the main body 1 is provided with an S-groove 213; Several arc-shaped pieces 214 are fixedly connected to the side wall of the sliding ring 211, and the arc-shaped pieces 214 are symmetrically distributed with the sliding ring 211 as the center. Two arc-shaped pieces 214 are provided. The movement of the arc-shaped pieces 214 reduces the jamming of the sliding ring 211 during sliding. The sliding ring 211 drives the sliding cylinder 221 to rotate through the fixed rod 212. The rotation of the sliding cylinder 221 drives the flag 4 to rotate synchronously. Since the sliding cylinder 221 is in contact with the side wall of the S-groove 213, when the sliding cylinder 221 is driven to rotate by the fixed rod 212, the sliding cylinder 221 will swing left and right under the guidance of the arc of the S-groove 213.

[0030] The swing assembly 22 includes a sliding cylinder 221 that is slidably connected to the bottom of the fixed rod 212, and a contact ball 222 is fixedly connected to one end of the sliding cylinder 221 near the side wall of the main body 1. Several springs 223 are fixedly connected to the side of the contact ball 222 near the sliding ring 211, and the several springs 223 are symmetrically distributed with the sliding ring 211 as the center. The end of spring 223 away from contact ball 222 is fixedly connected to the side wall of sliding ring 211; The sliding cylinder 221 slides through to the outside of the S-groove 213. The outer surface of the part of the sliding cylinder 221 that extends out of the side wall of the main body 1 is rotatably connected to the flag 4. Two springs 223 are provided. The springs 223 ensure the stability of the contact ball 222 in contact with the inner wall of the main body 1 when the contact ball 222 rotates. The sliding ring 211 will drive the sliding cylinder 221 to rotate synchronously. The contact ball 222 provided on the sliding cylinder 221 will rotate inside the main body 1. Since the main body 1 is in a quasi-elliptical state, when the fixed rod 212 rotates, the contact ball 222 will be affected by the shape of the main body 1 and squeezed and slid.

[0031] A ball bearing 224 is provided at the end of the spring 223 away from the contact ball 222, and the ball bearing 224 is rotatably connected to the arc-shaped plate 214.

[0032] The actuating assembly 23 includes a rotating disk 231 rotatably connected to the end of the contact ball 222 away from the sliding ring 211. Several actuating plates 232 are fixedly connected to the side wall of the rotating disk 231. The several actuating plates 232 are symmetrically distributed around the sliding cylinder 221. Several rubber sheets 233 are fixedly connected to the side wall of the rotating disk 231, and the rubber sheets 233 are distributed circumferentially around the contact ball 222. In the initial state, the rubber sheet 233 is in contact with the baffle 312, and the rotating disk 231 moves synchronously with the sliding cylinder 221. Since the rubber sheet 233 is in contact with the baffle 312, when the sliding cylinder 221 rotates, the friction between the rubber sheet 233 and the baffle 312 will drive the rotating disk 231 to rotate.

[0033] When in use, staff members climb to the position of seat 3 via step bar 313 to observe the situation on the field. When violations occur on the field, staff members press the external remote control, and the motor 111 at the bottom of seat 3 will be started. The motor 111 will rotate through the output shaft 112 to drive the flag 4 to rise gradually from the bottom to warn the participants, thereby raising and lowering the flag 4 on the side wall of the referee's chair.

[0034] When the motor 111 rotates, the sliding ring 211 drives the sliding cylinder 221 to rotate via the fixed rod 212. The rotation of the sliding cylinder 221 drives the flag 4 to rotate synchronously. Since the sliding cylinder 221 is in contact with the side wall of the S-groove 213, when the sliding cylinder 221 is driven to rotate by the fixed rod 212, the sliding cylinder 221 will swing left and right under the guidance of the arc of the S-groove 213. The swing of the sliding cylinder 221 will drive the sliding ring 211 to slide on the output shaft 112. At the same time, the motor 111 is constantly rotating, and the sliding cylinder 221 will move upward continuously when it swings. This reduces the situation where the movement mode of the fixed rod 212 is too monotonous and the warning effect is insufficient. This further improves the warning capability of the flag lifting device of the field judge's seat when it moves.

[0035] When the sliding ring 211 rotates with the output shaft 112, it drives the sliding cylinder 221 to rotate synchronously. The contact ball 222 on the sliding cylinder 221 rotates inside the main body 1. Since the main body 1 has a near-elliptical shape, when the fixed rod 212 rotates, the contact ball 222 will be affected by the shape of the main body 1 and will slide under pressure. The sliding cylinder 221 will slide towards the sliding ring 211, and the spring 223 will be compressed due to the sliding of the sliding cylinder 221. When the spring 223 is compressed to a certain distance, the continued compression of the spring 223 will bring... The contact ball 222 rotates, causing the sliding cylinder 221 to rotate synchronously. The rotation of the sliding cylinder 221 drives the flag 4, which is curled up at the bottom, to rotate until the flag is fully opened. When the sliding cylinder 221 returns to its original position, the compressed spring 223 gradually rebounds, and the sliding cylinder 221 rotates in the opposite direction, thereby retracting the unfolded flag 4. This reduces the swaying caused by wind and other external factors when the flag 4 is not raised, which could distract the competitors and further improves the stability of the flag 4 of the flag lifting device of the field event referee's seat.

[0036] When the sliding ring 211 slides, the sliding cylinder 221 is pushed by the S-shaped notch of the S-groove 213, which in turn drives the sliding ring 211 to slide via the fixed rod 212. Since the point of compression between the S-groove 213 and the sliding cylinder 221 is relatively far from the sliding axis of the sliding ring 211, the linkage formed by the sliding ring 211, fixed rod 212, and sliding cylinder 221 may tilt when the S-groove 213 pushes the sliding cylinder 221. Slight tilting of the sliding ring 211 can cause it to jam when sliding on the output shaft 112. When rotating, the arc-shaped piece 214 will contact the inner wall of the main body 1 and deform. When the arc-shaped piece 214 rotates to a certain angle, the ball bearing 224 will contact the inner wall of the main body 1 to ensure the normal rotation of the sliding ring 211. The deformation of the arc-shaped piece 214 will push the sliding ring 211 to fit tightly with the output shaft 112. When the sliding ring 211 slides, the pushing of the arc-shaped piece 214 reduces the tilting of the sliding ring 211. At the same time, the setting of the ball bearing 224 ensures the smoothness of the sliding ring 211, further improving the smoothness of the flag lifting device of the field judge's seat during movement.

[0037] When the sliding cylinder 221 rotates with the fixed rod 212, the rotating disk 231 will move synchronously with the sliding cylinder 221. Since the rubber sheet 233 is in contact with the baffle 312, when the sliding cylinder 221 rotates, the friction between the rubber sheet 233 and the baffle 312 will drive the rotating disk 231 to rotate. When the rotating disk 231 rises with the sliding cylinder 221, the rotation direction of the rotating disk 231 is opposite to the rotation direction of the sliding cylinder 221 when it slides. When the rotating disk 231 rotates, it will drive the actuating plate 232 to rotate synchronously. When the actuating plate 232 moves, it will actuate the edge of the flag 4. When the edge of the flag 4 is lifted by the actuating plate 232, the actuating plate 232 will enter the inside of the curled flag 4 and gradually open the curled flag 4. This reduces the situation where the curled flag 4 is fluffy but not fully opened when the sliding cylinder 221 rotates to the middle of the main body 1 and begins to rotate. This further improves the integrity of the flag opening of the flag lifting device of the field judge's seat.
