Description

Technical Field

[0001] This invention relates to the field of training equipment, and more particularly to a standing combat punching bag. Background Technology

[0002] A punching bag is a training tool used in combat sports, primarily for striking power training. The following standing punching bags are currently available:

[0003] The first type is the most common and widely used. Its basic structure consists of a water tank (or other heavy object) at the bottom for counterweight, a connecting rod connecting to a shock-absorbing spring, and sandbags connected to the top.

[0004] The second method involves installing force sensors on standing sandbags so that trainees know their training intensity.

[0005] The third option is to replace the sandbag with a boxing ball to simulate body shape, etc.

[0006] The fourth method involves connecting sandbags with other fitness equipment to create a comprehensive training system.

[0007] The fifth type is that the filling inside the sandbag is replaceable.

[0008] The above-mentioned types of standing sandbags each have the following disadvantages:

[0009] The first type has a very high base, with connecting rods and shock-absorbing springs in the middle. Only the upper and middle parts of the standing punching bag are available for athletes to train. However, the standing strikes in Muay Thai, kickboxing, and mixed martial arts are very three-dimensional. For example, low kicks and other lower body strikes are the main attack methods. When athletes perform low kicks, they will kick directly onto the connecting rods or shock-absorbing springs of the traditional standing punching bag.

[0010] The second type: a huge base without cushioning protection. When athletes are training in aerial leg techniques, they may land near the sandbag base, which could cause injury.

[0011] The third type: The height of the sandbag cannot be changed. For taller athletes, the height of the sandbag may not be enough for high roundhouse kicks or aerial leg techniques.

[0012] The fourth type: The hardness of the sandbag surface cannot be adjusted. Beginners are suitable for softer sandbags, while those who practice for a long time should slowly increase the hardness of the sandbag. This can train the shinbone and the bone density of the fist.

[0013] The fifth type: Traditional sandbags are purely cylindrical, making it impossible to train uppercuts in boxing and flying knees in knee techniques.

[0014] In summary, there is a need to design a standing combat punching bag that can simultaneously solve problems such as the inability to train in the lower part of the structure with connecting rods and shock-absorbing springs, the excessively large base lacking cushioning and easily causing injury to athletes, the inability to change the height of the punching bag, the inability to change the hardness of the punching bag, and the inability of the punching bag to train uppercuts.

[0015] Chinese invention patent CN 108635801 A discloses an indoor vertical fitness sandbag, comprising a sandbag body, an upper column, a lower column, and a fixed base at the bottom of the lower column. The upper and lower columns are connected by threads to adjust their overall length to fit snugly against the indoor ceiling. The sandbag body is a hollow cylindrical structure, with its bottom mounted on a support plate mechanism fixed to the upper column. A force-relieving component fixed to a fixed roller is disposed in the cavity in the middle of the sandbag body. The sandbag body contains an internal cavity filled with rigid material and an external cavity cushioned by elastic material. However, the base of the sandbag body in this invention lacks cushioning protection. When performing aerial leg techniques, the athlete may land near the base, potentially causing injury. Furthermore, the sandbag's purely cylindrical shape makes it unsuitable for training techniques such as uppercuts in boxing and flying knees in knee strikes. Summary of the Invention

[0016] In view of this, the purpose of this invention is to provide a standing combat punching bag.

[0017] To achieve the above-mentioned technical objectives, the technical solution adopted by this invention is as follows:

[0018] This invention provides a standing combat punching bag, comprising: a punching bag head, multiple punching bag necks, a punching bag body, a cushioning base assembly, a fixing screw, multiple anti-slip cushioning rings, and a cushioning support assembly. The bottom of the cushioning support assembly is fixed to the middle of the cushioning base assembly. The punching bag body is fitted onto the outer ring of the cushioning support assembly. The multiple anti-slip cushioning rings are arranged sequentially from bottom to top, with the bottom of the lowest anti-slip cushioning ring fixed to the top of the cushioning support assembly. The multiple punching bag necks and punching bag head are arranged sequentially from bottom to top onto the outer ring of the anti-slip cushioning rings. The bottom punching bag neck... The bottom of the punching bag contacts the top of the body, and the top of the uppermost neck contacts the bottom of the head. The lower end of the fixing screw is fixed inside the anti-slip buffer ring and the buffer support assembly, and the upper end of the fixing screw is locked to the top of the head and the uppermost anti-slip buffer ring. The height of the standing combat punching bag is adjusted according to the number of anti-slip buffer rings and the neck. The head, neck, and body of the punching bag are filled with filling material, and the hardness of the standing combat punching bag is adjusted according to the different materials used for the filling material. The head of the punching bag has a spherical structure.

[0019] Furthermore, the buffer support assembly includes a support rod with an elongated groove at its upper center and an internal thread on the inner wall of the groove; each anti-slip buffer ring has a through groove at its center, with an internal thread on the inner wall of the through groove; the fixing screw includes a horizontally arranged locking rod and a vertically arranged threaded rod, the upper end of the threaded rod being connected to the lower center of the locking rod, and the outer wall of the threaded rod having an external thread; the dimensions of the elongated groove, the through groove, and the threaded rod are matched to each other, and the threaded rod passes through multiple through grooves and elongated grooves in sequence through a threaded connection of external and internal threads; the locking rod is connected to the top of the sandbag head and the top of the uppermost anti-slip buffer ring.

[0020] Furthermore, on the upper surface of each anti-slip buffer ring, multiple limiting grooves are evenly distributed along a circumference with radius r formed at the center, and multiple limiting pins are provided on the lower surface of the anti-slip buffer ring at positions corresponding to the multiple limiting grooves; the limiting pins of the upper anti-slip buffer ring are inserted into the limiting grooves of the lower anti-slip buffer ring.

[0021] The buffer support assembly also includes a first buffer ring, which is sleeved on the outer ring of the support rod. The upper surface of the first buffer ring is provided with multiple limiting grooves at positions corresponding to multiple limiting pins. The limiting pin of the lowest anti-slip buffer ring is inserted into the limiting groove of the first buffer ring.

[0022] The locking rod is provided with multiple fixing holes that match the position of the limiting groove. When rotated into place, the multiple fixing holes and the limiting groove of the uppermost anti-slip buffer ring are on the same vertical line and are fixed by the fixing parts.

[0023] Furthermore, the fastener is a screw, the inner wall of the fixing hole is provided with internal threads, the upper part of the screw is provided with external threads, and the diameter of the upper part of the screw is larger than the diameter of the lower part; when locked in place, the lower part of the screw is precisely inserted into the limiting groove corresponding to the uppermost anti-slip buffer ring, and the screw and the locking rod are locked together by the cooperation of the external threads of the upper part of the screw and the internal threads of the fixing hole.

[0024] Furthermore, each of the anti-slip buffer rings has eight upper limit grooves and eight limit pins, with the angle between two adjacent limit grooves and the center being 45 degrees, and the two opposite limit grooves being located on the same horizontal line; the locking rod has two fixing holes.

[0025] Furthermore, the buffer support assembly also includes a bottom nut, the bottom of the support rod is provided with external threads, the bottom nut is provided with a mounting hole in the middle that matches the size of the support rod, the inner wall of the mounting hole is provided with internal threads, the bottom of the support rod passes through the buffer base assembly and is fixedly connected to the mounting hole by the engagement of external and internal threads.

[0026] Furthermore, the buffer base assembly includes a fixed base, multiple suction cups, and a buffer pad. The buffer pad is disposed on the upper surface of the fixed base, and the multiple suction cups are evenly disposed on the bottom of the fixed base, and the suction cups are attracted to the ground; the fixed base is a lead ring.

[0027] Furthermore, the height of each of the anti-slip buffer rings is the same as the height of each sandbag neck, and the height of the sandbag head is an integer multiple of the height of the anti-slip buffer ring; the height of the threaded rod is greater than the total height of all the anti-slip buffer rings and less than the sum of the total height of all the anti-slip buffer rings and the height of the long groove.

[0028] Furthermore, the filling material consists of wood chips and fine sand, and the hardness of the standing combat sandbag is controlled by adjusting the ratio of wood chips to fine sand.

[0029] Furthermore, the outer ring of the anti-slip buffer ring, the outer ring of the buffer support assembly, the inner ring of the sandbag head, the inner ring of the sandbag neck, and the inner ring of the sandbag body are all quincunx-shaped; the anti-slip buffer ring and the first buffer ring are both rubber sleeves, and the buffer pad is a rubber pad.

[0030] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0031] 1. A first buffer ring and an anti-slip buffer ring were added to the outer ring of the support rod and the threaded rod respectively for cushioning. In addition, the cushioning effect of the materials of the sandbag head, sandbag neck and sandbag body itself can be sufficient to replace the shock-absorbing spring. It is designed as an integral cushioning sandbag. The entire part of the standing combat sandbag can be used by athletes to train. Athletes can train low kicks and other lower limb attack movements.

[0032] 2. The fixed base of the cushioning base assembly is a lead ring used for counterweight to prevent the sandbag from tipping over. The upper surface of the fixed base is equipped with a cushioning pad, and the bottom of the fixed base is equipped with a suction cup to adhere to the ground and prevent the sandbag from tipping over. This greatly reduces the height of the center of gravity of the cushioning base assembly and increases the surface cushioning of the cushioning base assembly to protect athletes who may fall on the fixed base.

[0033] 3. The support rod and the fixing screw work together to determine the number of anti-slip buffer rings, the number of sandbag necks, and the height of the threaded rods according to the athlete's height, thereby determining the overall height of the standing combat sandbag, which can ensure that athletes of different heights can train.

[0034] 4. The ring-shaped body, neck, and head of the sandbag can be made of different materials to change the surface hardness of the sandbag. Athletes can change different materials according to the needs of different training stages. For example, if the filling is wood chips, the sandbag will be softer, and if the filling is fine sand, the sandbag will be harder. Adjusting the ratio of wood chips to fine sand can control the hardness of the sandbag and ensure that athletes can train at different stages.

[0035] 5. The structure of the sandbag head is spherical, which can be used to train punches and kicks that attack from the bottom up, such as uppercuts and flying knees. Attached Figure Description

Detailed Implementation

[0056] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the invention. Similarly, the following embodiments are only some, not all, embodiments of the present invention, and all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Please see Figures 1-17This invention discloses a standing combat punching bag, comprising: a punching bag head 1, multiple punching bag necks 2, a punching bag body 3, a cushioning base assembly 4, a fixing screw 5, multiple anti-slip cushioning rings 6, and a cushioning support assembly 7. The bottom of the cushioning support assembly 7 is fixed to the middle of the cushioning base assembly 4. The punching bag body 3 is fitted around the outer ring of the cushioning support assembly 7, and the bottom of the punching bag body 3 contacts the top of the cushioning base assembly 4. Both the punching bag body 3 and the cushioning support assembly 7 have a cushioning effect, which can enhance the athlete's training in this area. The height of the cushioning base assembly 4 is in the range of 5-10cm. Due to the small height of the cushioning base assembly 4, it can ensure that all training movements of the athlete are performed within the cushioned punching bag. The training is performed on the head 1, sandbag neck 2, and sandbag body 3, with the majority of the movements occurring on the sandbag body 3. Therefore, adding a cushioning support component 7 inside the sandbag body 3 provides secondary cushioning, improving the cushioning effect and ensuring the athlete's training effectiveness. Multiple anti-slip cushioning rings 6 are arranged sequentially from bottom to top, with the bottom of the upper anti-slip cushioning ring 6 connecting to the top of the lower anti-slip cushioning ring 6, and the bottom of the lowest anti-slip cushioning ring 6 fixed to the top of the cushioning support component 7. Multiple sandbag necks 2 and sandbag heads 1 are sequentially fitted onto the outer ring of the anti-slip cushioning rings 6 from bottom to top, with the bottom of the lowest sandbag neck 2 contacting the top of the sandbag body 3, and the top of the uppermost sandbag neck 2 contacting the sandbag body 3. The bottoms of the head 1 are in contact with each other. Since the neck 2, head 1, and anti-slip buffer ring 6 all have a cushioning effect, the athlete's training movements are performed on the cushioned head 1 and neck 2. Adding an anti-slip buffer ring 6 inside the head 1 and neck 2 provides secondary cushioning, improving the cushioning effect and thus ensuring the athlete's training effectiveness to a greater extent. The lower end of the fixing screw 5 is fixed inside the anti-slip buffer ring 6 and the buffer support assembly 7, and the upper end of the fixing screw 5 is locked to the top of the head 1 and the topmost anti-slip buffer ring 6. The fixing screw 5 can fix the position of the head 1, neck 2, body 3, anti-slip buffer ring 6, and buffer support assembly 7. To prevent athletes from shifting during training, which could affect training effectiveness or even pose safety hazards; the height of the standing combat punching bag is adjusted according to the number of anti-slip buffer rings 6 and punching bag necks 2. The number of anti-slip buffer rings 6, punching bag necks 2, and the height of the threaded rods 52 can be determined based on the height of different athletes, thus determining the overall height of the standing combat punching bag. This ensures that athletes of different heights can train, improving the applicability of the standing combat punching bag; the punching bag head 1, punching bag neck 2, and punching bag body 3 are filled with material, and the hardness of the standing combat punching bag is adjusted according to the different materials used for the filling. Standing combat punching bags with different hardnesses can ensure that athletes at different stages can train;The sandbag head 1 has a spherical structure, with both its upper and lower surfaces being flat circular shapes, and its sides being spherical. During training, the athlete's movements are concentrated on the side, providing good cushioning and allowing for the training of punches and kicks with upward attack trajectories, such as uppercuts and flying knees.

[0058] In this embodiment, the buffer support assembly 7 includes a support rod 71, with an elongated groove 711 at the upper center of the support rod 71, and an internal thread on the inner wall of the elongated groove 711; each anti-slip buffer ring 6 has a through groove 61 penetrating through its center, and the inner wall of the through groove 61 has an internal thread; the fixing screw 5 includes a horizontally arranged locking rod 51 and a vertically arranged threaded rod 52, the upper end of the threaded rod 52 being connected to the lower center of the locking rod 51, and the outer wall of the threaded rod 52 having an external thread; the dimensions of the elongated groove 711, the through groove 61, and the threaded rod 52 are matched to each other, and they engage through the external thread and the internal thread. The threaded connection allows the threaded rod 52 to pass through multiple through slots 61 and long slots 711 in sequence. The locking rod 51 is connected to the top of the sandbag head 1 and the top anti-slip buffer ring 6. The threaded rod 52 can fix the position of the buffer support assembly 7 and the anti-slip buffer ring 6. Since the sandbag body 3 is tightly fitted on the outside of the buffer support assembly 7, and the sandbag head 1 and sandbag neck 2 are tightly fitted on the outside of the anti-slip buffer ring 6, the positions of the sandbag head 1, sandbag neck 2 and sandbag body 3 are fixed. When the athlete is training, it can prevent the sandbag head 1, sandbag neck 2 and sandbag body 3 from moving, thereby improving the training effect.

[0059] In this embodiment, multiple limiting grooves 62 are evenly distributed on the upper surface of each anti-slip buffer ring 6 along a circumference with radius r formed at the center (center of the upper surface). Multiple limiting pins 63 are provided on the lower surface of the anti-slip buffer ring 6 at positions corresponding to the multiple limiting grooves 62. The limiting pins 63 of the upper anti-slip buffer ring 6 are inserted one by one into the limiting grooves 62 of the lower anti-slip buffer ring 6. Since the positions of the limiting grooves 62 and the limiting pins 63 are one-to-one and located on the same vertical line, during the process of the limiting pins 63 being inserted into the limiting grooves 62, it can be ensured that the limiting grooves 62 and the limiting pins 63 of all anti-slip buffer rings 6 are located on the same vertical line, thereby improving the stability of the anti-slip buffer ring 6 during the assembly process.

[0060] The buffer support assembly 7 also includes a first buffer ring 72, which is sleeved on the outer ring (outer side) of the support rod 71. The upper surface of the first buffer ring 72 is provided with multiple limiting grooves 62 at positions corresponding to multiple limiting pins 63. The limiting pin 63 of the lowermost anti-slip buffer ring 6 is inserted into the limiting groove 62 of the first buffer ring 72.

[0061] The locking rod 51 has multiple fixing holes 511 that match the position of the limiting groove 62. When rotated into place, the multiple fixing holes 511 and the limiting groove 62 of the uppermost anti-slip buffer ring 6 are on the same vertical line and are fixed by the fixing member 8. By locking the fixing holes 511 of the locking rod 51 to the limiting groove 62 of the anti-slip buffer ring 6 with the fixing member 8, the positions of the locking rod 51, the uppermost anti-slip buffer ring 6, and the sandbag head 1 can be limited to prevent displacement and improve the training effect. The structure of the limiting groove 62 and the limiting pin 63 makes operation simple and more flexible and convenient.

[0062] In this embodiment, the fixing member 8 is a screw, the inner wall of the fixing hole 511 is provided with internal threads, the upper part of the screw is provided with external threads, and the diameter of the upper part of the screw is larger than the diameter of the lower part. When locked in place, the lower part of the screw is precisely inserted into the limiting groove 62 corresponding to the uppermost anti-slip buffer ring 6. The screw and the locking rod 51 are locked together by the cooperation of the external thread of the upper part of the screw and the internal thread of the fixing hole 511. The structure of the screw can limit the position between the locking rod 51 and the uppermost anti-slip buffer ring 6, and also ensure that the locking rod 51 is fixed on the top of the sandbag head 1 and the uppermost anti-slip buffer ring 6.

[0063] In this embodiment, each anti-slip buffer ring 6 has eight upper limit grooves 62 and eight limit pins 63, with the eight limit grooves 62 cooperating with the eight limit pins 63; the angle between two adjacent limit grooves 62 and the center is 45 degrees, and the two opposite limit grooves 62 are located on the same horizontal line; the locking rod 51 has two fixing holes 511, which are located on both sides of the center and correspond one-to-one with the positions of the two limit grooves 62 on the same horizontal line in the anti-slip buffer ring 6; every time the fixing screw 5 rotates 45 degrees, the two fixing holes 511 on the fixing screw 5 have a chance to align with two limit grooves 62 on the upper part of the anti-slip buffer ring 6 that are on the same horizontal line, and a suitable position can be found to install the set screw.

[0064] In this embodiment, the buffer support assembly 7 further includes a bottom nut 73, the bottom of the support rod 71 is provided with an external thread, the bottom nut 73 is provided with a mounting hole 731 in the middle that matches the size of the support rod 71, the inner wall of the mounting hole 731 is provided with an internal thread, the bottom of the support rod 71 passes through the buffer base assembly 4 and is fixedly connected to the mounting hole 731 by the engagement of the external thread and the internal thread.

[0065] In this embodiment, the buffer base assembly 4 includes a fixed base 41, multiple suction cups 42, and a buffer pad 43. The buffer pad 43 is disposed on the upper surface of the fixed base 41, increasing the surface buffer of the buffer base assembly 4 to protect athletes who may fall onto the fixed base 41. Multiple suction cups 42 are evenly distributed at the bottom of the fixed base 41, and the suction cups 42 adhere to the ground, increasing the stability of the sandbag. The fixed base 41 is a lead ring, meaning that a ring of lead is used as a counterweight to lower the center of gravity and enhance the stability of the sandbag. The outer end of the fixed base 41 is provided with support feet for support.

[0066] In this embodiment, the height of each anti-slip buffer ring 6 is the same as the height of each sandbag neck 2. The height of the sandbag head 1 is an integer multiple of the height of the anti-slip buffer ring 6. Optional integer multiples n include 2, 3, etc. Therefore, when the number of anti-slip buffer rings 6 is m, m > n, the number of sandbag heads 1 is 1, and the number of sandbag necks 2 is mn. Here, the height of the sandbag head 1 is chosen to be twice the height of the anti-slip buffer ring 6. Therefore, when the number of anti-slip buffer rings 6 is 4, the number of sandbag heads 1 is 1, and the number of sandbag necks 2 is 2. The height of the threaded rod 52 is greater than the total height of all anti-slip buffer rings 6 and less than the sum of the total height of all anti-slip buffer rings 6 and the height of the long groove 711.

[0067] In this embodiment, the filling material is wood chips and fine sand. The hardness of the standing combat punching bag is controlled by adjusting the ratio of wood chips to fine sand. The punching bag body 3, punching bag neck 2, and punching bag head 1 form a complete kit and can be designed with different material hardnesses. Different kits can be flexibly selected to change the hardness and allow for flexible combinations. For example: Kit 1: The ratio of wood chips to fine sand in the punching bag head 1, punching bag neck 2, and punching bag body 3 is 1:3 (hardness level 1); Kit 2: The ratio of wood chips to fine sand in the punching bag head 1, punching bag neck 2, and punching bag body 3 is 1:2 (hardness level 2); Kit 3: The ratio of wood chips to fine sand in the punching bag head 1, punching bag neck 2, and punching bag body 3 is... The ratio is 1:1 (hardness level 3). Kit 4: The ratio of wood chips to fine sand in the head 1, neck 2, and body 3 is 2:1 (hardness level 4). A higher hardness level indicates a harder material. Athletes starting from the beginner level should begin with a softer sandbag and can initially choose Kit 1. After training for a period, they can switch to Kit 2, Kit 3, Kit 4, etc., based on their results. Furthermore, the hardness levels of the head 1, neck 2, and body 3 can also be different. The ratio of wood chips to fine sand in the head 1, neck 2, and body 3 can also be customized to meet the needs of athletes at different training stages.

[0068] In this embodiment, the outer ring of the anti-slip buffer ring 6, the outer ring of the buffer support component 7, the inner ring of the sandbag head 1, the inner ring of the sandbag neck 2, and the inner ring of the sandbag body 3 are all quincunx-shaped. The number of petals in the quincunx shape can be 4, 5, 6, etc. Here, 4 is used as an example. The outer part of the anti-slip buffer ring and the buffer support component adopts a quincunx-shaped structure, which can circumferentially position the sandbag body 3, the sandbag neck 2, and the sandbag head 1, preventing the sandbag body 3, the sandbag neck 2, and the sandbag head 1 from rotating. The sandbag head 1, the sandbag neck 2, and the sandbag body 3 are annular structures. The sandbag head 1 has a first inner cavity 11, the sandbag neck 2 has a second inner cavity 21, and the sandbag body 3 has a third inner cavity 31. The first inner cavity 11, the second inner cavity 21, and the third inner cavity 31 are all quincunx-shaped.

[0069] In this embodiment, the anti-slip buffer ring 6 and the first buffer ring 72 are both rubber rings, and the buffer pad 43 is a rubber pad.

[0070] The installation sequence of the standing combat sandbag is as follows: First, install the cushioning support component 7 on the cushioning base component 4, tighten the bottom nut 73 with a tool, then insert the ring-shaped sandbag body 3, and then insert multiple anti-slip cushioning rings 6 (the number of anti-slip cushioning rings 6 depends on the height) and string them together; then string the ring-shaped sandbag neck 2 (the number is two less than the number of anti-slip cushioning rings 6, and the height of the sandbag head 1 is the height of two anti-slip cushioning rings 6), and then string the spherical sandbag head 1; finally, insert the fixing screw 5 through the anti-slip cushioning ring 6 embedded in the sandbag head 1 and lock it in place (it can be tightened with a tool), and after rotating the fixing screw 5 into place, install screws on the fixing hole 511 and the limiting groove 62 of the uppermost anti-slip cushioning ring 6 (the screw wrench is a special tool for sandbags, with two cylindrical pins on one end for tightening the fixing screw, and a hexagonal socket on the other end for tightening the cushioning support component and the bottom nut).

[0071] The above description is only a part of the embodiments of the present invention and does not limit the scope of protection of the present invention. Any equivalent device or equivalent process transformation made based on the content of the present invention specification and drawings, or direct or indirect application in other related technical fields, are similarly included within the patent protection scope of the present invention.
