Description

Technical Field

[0001] The utility model relates to the technical field of speed arms, in particular to a new type of multifunctional speed arm. Background Art

[0002] A speed arm is a fitness device used to exercise the arm and shoulder muscles. It usually has an eight-shaped design and weighs generally between 8 and 12 pounds, and can play a role similar to dumbbells during rapid movement.

[0003] The current speed arm products on the market mainly adopt a solid heavy metal steel material, and the counterweight part is often designed as an immovable square steel structure. Although this design ensures the durability of the product, due to the fixity of the counterweight and the hardness of the material, if the user operates carelessly, it may increase the risk of accidental injury. In addition, due to the limitations of its weight and size, such speed arms are usually only suitable for adult use, resulting in a relatively narrow target market. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that there are disadvantages in the prior art that the counterweight cannot be adjusted and it is relatively easy to cause harm to the user. For this reason, we propose a new type of multifunctional speed arm.

[0005] In order to achieve the above purpose, the present application adopts the following technical solution: a new type of multifunctional speed arm, including an upper shell, the number of the upper shells is two, the bottom end of the upper shell is provided with two lower shells, the bottom end of the upper shell is provided with an upper counterweight wrapper, the top end of the lower shell is provided with a lower counterweight wrapper, several counterweight bodies are installed inside the upper counterweight wrapper and the lower counterweight wrapper, a control board is installed inside the lower counterweight wrapper, a display and a charging port are installed on the surface of the control board, a battery and a speaker are also installed inside the lower counterweight wrapper, an inductor is installed in the gap between the counterweight bodies, and a magnet is installed between the friction block and the adjusting nut.

[0006] Preferably, an adjusting screw is rotatably connected inside the upper shell, two friction blocks are installed on the surface of the adjusting screw, adjusting nuts are installed on one side of each friction block, and a regulator is installed at the middle position of the adjusting screw.

[0007] Preferably, the friction block and the adjusting nut are designed in a hexagonal shape, and hexagonal guide grooves are provided inside both the upper shell and the lower shell.

[0008] Preferably, ultrasonic welding processes are provided inside the upper shell, the lower shell, the upper counterweight wrapper and the lower counterweight wrapper.

[0009] Preferably, a small cover is installed on the surface of the lower counterweight wrapper.

[0010] Technical effects and advantages of the present utility model:

[0011] In the present utility model, when the user group needs to adjust the usage weight, the upper shell and the upper counterweight wrapping piece are removed in sequence. At this time, the counterweight body inside the upper counterweight wrapping piece will be exposed. Then, the counterweight body is increased or decreased according to the usage requirements to achieve the weight adjustment. Moreover, the counterweight body is made of refined round steel and wrapped with high-quality ABS engineering plastic on the outside to prevent accidental injury to the user during product use and improve the applicable range and safety during use of the product.

[0012] In the present utility model, when the staff needs to increase or decrease the friction force, the regulator is rotated to drive the adjusting screw to rotate simultaneously, so that the positive and reverse threads of the adjusting screw move the adjusting nut inwards or outwards, achieving the purpose of increasing the friction force between the friction block and the upper counterweight wrapping piece and the lower counterweight wrapping piece or reducing it to relieve the friction force, and further improving the usage experience.

[0013] In the present utility model, when the inductor detects the signal of the magnetic steel, the battery starts to supply power and the electronic components start to work. The inductor detects a signal once when the magnetic steel rotates one circle. At this time, the display shows the number of circles. At the same time, the speaker starts to broadcast voice synchronously. In the case that the device is not in use, it can be charged through the charging port with an ordinary charger, without the need to frequently replace the battery, significantly reducing the usage cost.

[0022] Refer to Figure 1 - Figure 3 As shown, the present utility model provides a technical solution: a new type of multifunctional speed arm, including two upper housings 1. At the bottom end of the upper housing 1, two lower housings 2 are installed. At the bottom end of the upper housing 1, an upper counterweight wrapper 3 is installed. At the top end of the lower housing 2, a lower counterweight wrapper 4 is installed. Inside the upper counterweight wrapper 3 and the lower counterweight wrapper 4, several counterweight bodies 6 are installed. Inside the lower counterweight wrapper 4, a control board 11 is installed. On the surface of the control board 11, a display 12 and a charging port 13 are installed. Inside the lower counterweight wrapper 4, a battery 14 and a speaker 15 are also installed. An inductor 16 is installed in the gap of the counterweight body 6. A magnet 17 is installed between the friction block 7 and the adjusting nut 8. When the inductor 16 detects the signal of the magnet 17, the battery 14 starts to supply power, and the electronic components start to work. When the magnet 17 rotates one circle, the inductor 16 detects a signal once. At this time, the display 12 shows the number of circles, and at the same time, the speaker 15 starts to synchronously voice broadcast. When the device is not in use, it can be charged through the charging port 13 with an ordinary charger, without having to frequently replace the battery 14, significantly reducing the use cost. When the user group needs to adjust the use weight, the upper housing 1 and the upper counterweight wrapper 3 are removed in sequence. At this time, the counterweight body 6 inside the upper counterweight wrapper 3 will be exposed. Then, the counterweight body 6 is increased or decreased according to the use requirements to achieve the weight adjustment. Moreover, the counterweight body 6 is made of refined round steel and wrapped with high-quality ABS engineering plastic on the outside to prevent accidental injury to the user during product use and improve the applicable range and safety during use of the product.

[0023] Refer to Figure 3As shown, in this embodiment: An adjusting screw rod 10 is rotatably connected inside the upper outer shell 1. Two friction blocks 7 are installed on the surface of the adjusting screw rod 10. Adjusting nuts 8 are installed on one side of each friction block 7. A regulator 9 is installed at the middle position of the adjusting screw rod 10. When the staff needs to increase or decrease the friction force, the regulator 9 is rotated to drive the adjusting screw rod 10 to rotate simultaneously. The positive and reverse threads of the adjusting screw rod 10 cause the adjusting nuts 8 to move inwards or outwards, so as to increase the friction force between the friction blocks 7 and the upper counterweight wrapper 3 and the lower counterweight wrapper 4 or reduce it to relieve the friction force, further improving the use experience.

[0024] Refer to Figure 3 As shown, in this embodiment: The friction blocks 7 and the adjusting nuts 8 are of hexagonal design. Hexagonal guide grooves 18 are provided inside both the upper outer shell 1 and the lower outer shell 2. Through the settings of the hexagons and the hexagonal guide grooves 18, the device can be more smooth and misalignment-free when adjusting the resistance, thus improving the efficiency during resistance adjustment.

[0025] Refer to Figure 1 - Figure 3 As shown, in this embodiment: Ultrasonic welding processes are provided inside the upper outer shell 1, the lower outer shell 2, the upper counterweight wrapper 3 and the lower counterweight wrapper 4. Through the settings of the ultrasonic welding processes, the appearance of the device can be more delicate and the touch can be more comfortable, and the overall structure can be more firm, effectively improving the use comfort of the user.

Through the setting of the small cover 5, the control board 11 inside the device can be quickly repaired or after-saled during use, reducing the disassembly time during maintenance.

[0027] Working principle: When the user group needs to adjust the usage weight, the upper shell 1 and the upper counterweight wrapper 3 are removed in sequence. At this time, the counterweight body 6 inside the upper counterweight wrapper 3 will be exposed. Then, the counterweight body 6 is increased or decreased according to the usage requirements to achieve the weight adjustment. The counterweight body 6 is made of refined round steel and wrapped with high-quality ABS engineering plastic on the outside to prevent accidental injury to the user during product use, improve the applicable range of the product and the safety during use. When the staff needs to increase or decrease the friction, the regulator 9 is rotated to drive the adjusting screw 10 to rotate simultaneously, so that the positive and reverse threads of the adjusting screw 10 move the adjusting nut 8 in or out, achieving the purpose of increasing the friction between the friction block 7 and the upper counterweight wrapper 3 and the lower counterweight wrapper 4 or reducing it to relieve the friction, further improving the use experience. When the sensor 16 detects the signal of the magnet 17, the battery 14 starts to supply power and the electronic components start to work. The sensor 16 detects a signal once when the magnet 17 rotates one circle. At this time, the display 12 shows the number of circles, and at the same time, the speaker 15 starts to synchronously voice broadcast. When the device is not in use, it can be charged through the charging port 13 with an ordinary charger, without having to frequently replace the battery 14, significantly reducing the use cost. Through the setting of the hexagon and the hexagonal guide groove 18, the device can be adjusted more smoothly and without dislocation when adjusting the resistance, thus improving the efficiency during resistance adjustment. Through the setting of the ultrasonic welding process, the appearance of the device can be more delicate and the touch can be more comfortable, and it has a more solid overall structure, effectively improving the use comfort of the user. Through the setting of the small cover 5, the control board 11 inside the device can be quickly repaired or after-sales processed during use, reducing the disassembly time during maintenance.
