Description

Technical Field

[0001] This utility model relates to the field of elliptical machine technology, and in particular to a turntable fixing structure for an elliptical machine. Background Technology

[0002] The elliptical trainer is a common cardiovascular fitness training tool. It is primarily driven by the user's legs, with the hands providing additional propulsion by gripping and pulling the handles. With hands below shoulder height, the user pushes and pulls the handles back and forth, while the feet pedal in the opposite direction. The back-and-forth swinging of the arms and the forward and backward movement of the pedals work in tandem, simulating movements such as running and climbing stairs, to promote fat breakdown through low-to-moderate intensity continuous exercise.

[0003] When installing the turntable on an elliptical machine, it is usually installed by using a locking block inside the turntable housing to cooperate with the rod near the shaft of the equipment frame. After the locking block inside the turntable housing is engaged with the inside of the rod, the outer surface of the turntable housing is relatively smooth and fits tightly against the surface of the equipment frame, making it difficult to pull the turntable housing outward when removing it. This makes it inconvenient to disassemble and maintain the turntable of the elliptical machine. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when the inner side of the turntable shell is stuck inside the rod, the outer surface of the turntable shell is relatively smooth and fits tightly with the surface of the equipment frame, making it difficult to pull the turntable shell outward when removing it, which makes it inconvenient to disassemble and maintain the turntable of the elliptical machine. Therefore, this utility model proposes a turntable fixing structure for elliptical machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a turntable fixing structure for an elliptical machine, comprising a frame rod, a device frame for mounting the frame rod on one side, a shaft rod rotatably connected to one side of the device frame, the frame rod and the shaft rod being fixed together by bolts, auxiliary rods fixedly connected to both sides of the frame rod, a slot being provided on one side of the auxiliary rod, a turntable shell being mounted on one side of the frame rod with the aid of two sets of auxiliary structures, a plurality of fixing plates being fixedly connected to the inner wall of the turntable shell, a locking rod being fixedly connected to the inner wall of the turntable shell, and two protrusions being provided on the outer surface of the locking rod for locking onto the outer surface of the frame rod.

[0006] Preferably, the auxiliary structure includes a triangular disk, a plastic folding piece fixedly connected to one side of the triangular disk, the folding piece being fixedly connected to one side of the outer surface of the turntable shell, a card fixedly connected to one side of the triangular disk, two grooved rods fixedly connected to one side of the triangular disk, a slider slidably connected to the inner wall of the grooved rods, a spring provided at one end of the slider, the two ends of the spring being fixedly connected to one side of the inner wall of the grooved rod and one end of the slider, respectively, and several round rods fixedly connected to the inner wall of the turntable shell, the ends of the round rods away from the turntable shell being fixedly connected to one side of the slider.

[0007] The effect achieved by the above components is as follows: By setting up the triangular disc, when installing the turntable, the inward-facing side of the turntable shell is clamped onto one side of the support rod, so that the two protrusions on the outer surface of the rod on the inner wall of the turntable shell are respectively clamped onto the two sides of the outer surface of the support rod. At the same time, pulling the triangular disc controls the triangular disc to extend and rotate away from the turntable shell through the folding piece. The slider will slide on the inner wall of the groove rod and compress the spring, so that the protrusion at one end of the card can enter the groove on the side of the auxiliary rod. Releasing the triangular disc and restoring the spring to its original state will push the slider to make the triangular disc fit against the outer surface of the turntable shell. At this time, the protrusion at one end of the card... The turntable shell is fixed to the side of the support rod by locking the slot inside the slot. Then, the support rod is connected to the shaft on the equipment frame using fasteners. When the turntable shell needs to be removed, pull the triangular discs at the two triangular discs to control the triangular discs to rotate away from the turntable shell through the folding piece. This causes the slider to move inside the slot rod and compress the spring, controlling the card on one side of the triangular disc to move away from the slot on the side of the support rod. This makes it easier to control the turntable shell to first release its fixation to the support rod, and then pull the turntable shell outward to make the locking rod detach from the outer surface of the support rod.

[0008] Preferably, a rubber sheet is provided at one end edge of the slider facing the round rod.

[0009] The effect achieved by the above components is that when the slider moves inside the groove, it will squeeze the side close to the round rod. By setting a rubber sheet, the rubber sheet can be deformed when the slider moves inside the groove, which helps the slider move smoothly.

[0010] Preferably, a positioning rod is fixedly connected to the inner wall of the groove rod, the slider slides on the outer surface of the positioning rod, and the spring is sleeved on the outer side of the positioning rod.

[0011] The effect achieved by the above components is that when the slider moves inside the groove rod and causes the spring to deform, the spring will move outside the positioning rod. The positioning rod can reinforce the internal shape of the spring and prevent the spring from twisting laterally.

[0012] Preferably, a support rod is fixedly connected to one side of the groove rod, and the end of the support rod away from the groove rod is fixedly connected to one side of the turntable shell.

[0013] The effect achieved by the above components is that by setting up support rods, the connection between the groove rod and the turntable shell can be reinforced, thereby improving the overall structural strength of the auxiliary structure.

[0014] Preferably, an operating block is fixedly connected to the side of the triangular disk away from the card, and the outer surface of the operating block is provided with several protrusions.

[0015] The effect achieved by the above components is that pinching the protrusion on the outer surface of the operating block makes it easier to pull the triangular disc outward and rotate it.

[0016] Preferably, a baffle is fixedly connected to one side edge of the triangular disk, and the baffle is attached to the outer edge of the turntable shell.

[0017] The effect achieved by the above components is that by setting the baffle, the position of the triangular disk on the outer surface of the turntable shell can be further restricted, preventing the edge of the triangular disk from embedding into the lower part of the outer surface of the turntable shell.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] In this invention, by setting an auxiliary structure and installing two rotatable triangular discs on the inner side of the turntable shell, when removing the turntable shell, rotating the triangular discs outward can cause the protrusion at one end of the card to first disengage from the slot on one side of the auxiliary rod, thereby releasing the fixation between the turntable shell and the auxiliary rod. This facilitates the subsequent release of the fixation between the card rod on one side of the turntable shell and the frame rod, improving the convenience of disassembling and assembling the turntable shell.

[0029] Example 1, as Figure 1-5 As shown, a turntable fixing structure for an elliptical machine includes a frame rod 1. A device frame 4 for mounting the frame rod 1 is provided on one side of the frame rod 1. A shaft rod 5 is rotatably connected to one side of the device frame 4. The frame rod 1 and the shaft rod 5 are fixed together by bolts. Auxiliary rods 3 are fixedly connected to both sides of the frame rod 1. A slot is provided on one side of the auxiliary rod 3. A turntable shell 6 is installed on one side of the frame rod 1 with the help of two sets of auxiliary structures 2. Several fixing plates 7 are fixedly connected to the inner wall of the turntable shell 6. A locking rod 8 is fixedly connected to the inner wall of the turntable shell 6. Two protrusions are provided on the outer surface of the locking rod 8 for locking onto the outer surface of the frame rod 1.

[0030] Reference Figure 1-8As shown, in this embodiment: the auxiliary structure 2 includes a triangular disk 21, a plastic folding piece 22 is fixedly connected to one side of the triangular disk 21, the folding piece 22 is fixedly connected to one side of the outer surface of the turntable shell 6, a card 23 is fixedly connected to one side of the triangular disk 21, two grooved rods 24 are fixedly connected to one side of the triangular disk 21, a slider 26 is slidably connected to the inner wall of the grooved rods 24, a spring 27 is provided at one end of the slider 26, the two ends of the spring 27 are fixedly connected to one side of the inner wall of the grooved rods 24 and one end of the slider 26 respectively, and several round rods 25 are fixedly connected to the inner wall of the turntable shell 6. One end of the turntable shell 6 is fixedly connected to one side of the slider 26. By setting the triangular disk 21, when installing the turntable, the inward side of the turntable shell 6 is clamped onto one side of the support rod 1, so that the two protrusions on the outer surface of the clamping rod 8 on the inner wall of the turntable shell 6 are respectively clamped onto the two sides of the outer surface of the support rod 1. At the same time, pulling the triangular disk 21 controls the triangular disk 21 to extend through the folding piece 22 and rotate away from the turntable shell 6. The slider 26 will slide on the inner wall of the groove rod 24 and compress the spring 27, so that the protrusion at one end of the card 23 can enter the groove on one side of the auxiliary rod 3. Releasing the triangular disk 21 and the spring 27 will return to their original state and push The sliding block 26 causes the triangular disk 21 to fit against the outer surface of the turntable shell 6. At this time, the protrusion at one end of the card 23 will lock into the slot on one side of the auxiliary rod 3, fixing the position of the turntable shell 6 on the support rod 1. Then, the support rod 1 and the shaft 5 on the equipment frame 4 are connected by fasteners. When it is necessary to remove the turntable shell 6, pull the triangular disk 21 at each of the two triangular disks to control the triangular disk 21 to rotate away from the turntable shell 6 through the folding piece 22. This causes the sliding block 26 to move inside the slot rod 24 and compress the spring 27, controlling the card 23 on one side of the triangular disk 21 to move away from the auxiliary rod 3. The inside of the side slot facilitates the control of the turntable shell 6 to first release the fixation from the auxiliary rod 3, and then pull the turntable shell 6 outward to make the locking rod 8 disengage from the outer surface of the frame rod 1. By setting the auxiliary structure 2, two rotatable triangular disks 21 are installed on the inside of the turntable shell 6. When removing the turntable shell 6, rotating the triangular disks 21 outward can make the protrusion at one end of the card 23 disengage from the slot on one side of the auxiliary rod 3 first, thereby releasing the fixation between the turntable shell 6 and the auxiliary rod 3. This facilitates the subsequent release of the locking rod 8 on one side of the turntable shell 6 from the frame rod 1, improving the convenience of disassembling and assembling the turntable shell 6.

[0031] Reference Figure 2-8As shown in this embodiment: a rubber sheet is provided at the edge of the slider 26 facing the round rod 25. When the slider 26 moves inside the groove rod 24, it will squeeze the side close to the round rod 25. By providing the rubber sheet, the slider 26 can be deformed by the compression when it moves inside the groove rod 24, which helps the slider 26 to move smoothly. A positioning rod 28 is fixedly connected to the inner wall of the groove rod 24. The slider 26 slides on the outer surface of the positioning rod 28. The spring 27 is sleeved on the outside of the positioning rod 28. When the slider 26 moves inside the groove rod 24 and causes the spring 27 to deform, the spring 27 will move on the outside of the positioning rod 28. The positioning rod 28 can reinforce the internal shape of the spring 27 and prevent the spring 27 from twisting laterally.

[0032] Reference Figure 4-8 As shown in this embodiment: a support rod 29 is fixedly connected to one side of the groove rod 24, and the end of the support rod 29 away from the groove rod 24 is fixedly connected to one side of the turntable shell 6. By setting the support rod 29, the connection between the groove rod 24 and the turntable shell 6 can be reinforced, thereby improving the overall structural strength of the auxiliary structure 2. An operating block 210 is fixedly connected to the side of the triangular disk 21 away from the card 23. Several protrusions are provided on the outer surface of the operating block 210. By pinching the protrusions on the outer surface of the operating block 210, the triangular disk 21 can be pulled outward more conveniently to rotate.

[0033] Reference Figure 4-8 As shown in this embodiment: a baffle 211 is fixedly connected to one side edge of the triangular disk 21. The baffle 211 is attached to the outer edge of the turntable shell 6. By setting the baffle 211, the position of the triangular disk 21 on the outer surface of the turntable shell 6 can be further restricted, so as to prevent the edge of the triangular disk 21 from being embedded below the outer surface of the turntable shell 6.

[0034] Working principle: When installing the turntable, the inward-facing side of the turntable shell 6 is clamped onto one side of the support rod 1, so that the two protrusions on the outer surface of the clamping rod 8 on the inner wall of the turntable shell 6 are respectively clamped onto the two sides of the outer surface of the support rod 1. At the same time, pulling the triangular disk 21 controls the triangular disk 21 to extend through the folding piece 22 and rotate away from the turntable shell 6. The slider 26 will slide on the inner wall of the groove rod 24 and compress the spring 27, so that the protrusion at one end of the card 23 can enter the groove on one side of the auxiliary rod 3. Releasing the triangular disk 21 and the spring 27 returning to their original state will push the slider 26 to make the triangular disk 21 fit against the outer surface of the turntable shell 6. At this time, the protrusion at one end of the card 23 will be clamped onto the auxiliary rod. The turntable shell 6 is fixed to the position of the support rod 1 on one side of the slot on one side of the support rod 3. Then the support rod 1 is connected to the shaft rod 5 on the equipment frame 4 by fasteners. When the turntable shell 6 needs to be removed, pull the triangular disk 21 at the two triangular disks 21 respectively to control the triangular disk 21 to rotate away from the turntable shell 6 through the folding piece 22. This causes the slider 26 to move inside the slot rod 24 and compress the spring 27. This controls the card 23 on one side of the triangular disk 21 to move away from the slot on the side of the auxiliary rod 3. This makes it easier to control the turntable shell 6 to first release the fixation from the auxiliary rod 3. Then the turntable shell 6 is pulled outward to make the card rod 8 separate from the outer surface of the support rod 1.
