Description

Technical Field

[0001] The invention relates to the technical field of office equipment, in particular to an electric lift fitness table. Background Art

[0002] At present, the fast-paced life makes people's work full of great pressure. High-intensity and long-term work is bound to affect people's physical health; diseases such as cervical spondylosis, sciatica, and lumbar disc herniation are gradually shifting from being prevalent in older people to being prevalent in younger people. Physical health issues are increasingly attracting people's attention and concern.

[0003] In their spare time, people often participate in outdoor activities and physical exercise to improve their physical fitness. However, due to work schedule constraints, most office workers return home very late after get off work. Combined with the fatigue of the day, they quickly fall into bed to rest, preventing their bodies from getting effective exercise. This can lead to illness over time. Currently, office facilities in most office buildings and factories generally include a desk and a matching office chair, along with essential office equipment such as computers and calculators. This office facility is primarily used for work, and people spend most of their time sitting in front of a computer. This limited range of motion for their legs, feet, and waist can seriously affect their health over time. Some offices or work areas have dedicated fitness areas, but if one or more people exercise in these areas while working, it can disrupt their colleagues. Therefore, the idea of ​​having fitness areas in offices is not widely accepted.

[0004] For the sake of health, most existing office desks are designed to be height-adjustable, with adjustable heights. This is intended to promote or guide people to adopt a healthy work style, alternating between standing and sitting. With the continuous improvement of living standards and technological advancements, people's demands for desk quality and functionality are also increasing. People not only want desks that provide common office and storage functions, but also want them to facilitate exercise without disturbing others. Clearly, existing electric height-adjustable desks fail to meet these user needs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned prior art and provide an electric lift fitness table that can be used for office work and appropriately assist in physical exercise without affecting the work of others during physical exercise.

[0006] The technical solution of the present invention is to provide an electric lifting fitness table with the following structure:

[0007] A table top body, a base, and a lifting assembly connecting the table top body and the base and capable of adjusting the height of the table top body relative to the base;

[0008] The telescopic assembly is connected to the bottom of the table board body and rises and falls synchronously with the table board body; the telescopic assembly has two horizontally arranged telescopic rods distributed along the length of the table board body, and the telescopic rods can be extended and retracted along the axial direction to put the telescopic assembly in an extended state or a retracted state;

[0009] An auxiliary fitness component includes a fitness bar extending along the length direction of a table body and two connecting rods connected to the fitness bar and corresponding to the two telescopic rods respectively; the free ends of the two connecting rods are rotatably connected to the outer ends of the two telescopic rods, respectively, for rotating and switching the auxiliary fitness component between a first position and a second position when the telescopic assembly is in an expanded state; wherein, when the auxiliary fitness component is in the first position, the axis of the connecting rod coincides with the axis of the telescopic rod, and the fitness bar is located below the table body; when the auxiliary fitness component is in the second position, the fitness bar is located above the table body.

[0010] After adopting the above structure, the electric lift fitness table of the present invention has the following advantages compared with the prior art:

[0011] The bottom of the table body of the electric lift fitness table is connected to an auxiliary fitness component through a telescopic component. The telescopic rod is axially extended and retracted to put the telescopic component in an expanded state or a retracted state. Therefore, the auxiliary fitness component can move relative to the table body under the action of the telescopic component, so that the fitness bar can be pulled out or retracted into the table body; because the two connecting rods on the fitness bar can rotate relative to the outer ends of the two telescopic rods, and when the telescopic component is in the expanded state, the fitness bar assembly can rotate upward around its rotation axis until the fitness bar is located above the table body, and the fitness bar located above the table body is used for users to exercise or do yoga; in this way, when the user feels tired after working for a long time in front of the electric lift table or during non-working hours, he can stand in front of the table body, pull the auxiliary fitness component out of the table body and flip it upward The auxiliary fitness component allows the fitness bar to be flipped over to the top of the table body, and the fitness bar can be used for yoga training, back muscle training, arm muscle training, etc., thereby relieving work fatigue and being more conducive to efficient work; when the training is finished, the auxiliary fitness component is flipped back to the first position, that is, the connecting rod on the fitness bar is in a horizontal state, and the fitness bar is retracted into the table body by using the telescopic component, so as not to occupy the user's work space; therefore, the electric lift fitness table allows users to work and exercise properly without affecting the work of others, its structure is simple, the setting is reasonable, and the remaining space of the electric lift table can be fully utilized; furthermore, the fitness bar can be raised and lowered synchronously with the table body, thereby meeting the fitness needs of users of different heights.

[0012] Preferably, the fitness bar is rotatably connected to a support frame, which can be rotated around the axis of the fitness bar between an unfolded position and a folded position. When the auxiliary fitness component is rotated upward around its rotation axis to a second position and the support frame is in the unfolded position, the bottom of the support frame abuts against the top of the table body to support the fitness bar. This support frame provides support for the fitness bar. That is, when the auxiliary fitness component is rotated upward around its rotation axis until the fitness bar is above the table body, the support frame can be rotated to open, so that the lower end of the support frame is supported on the table body. This improves the load-bearing capacity of the fitness bar and provides more stable support.

[0013] Preferably, the telescopic rod comprises an outer tube connected to the bottom of the table plate body and an inner tube slidingly fitted in the outer tube, the free end of the connecting rod is rotatably connected to the outer end of the inner tube; a locking hole is provided on the outer tube, and a radially slidable locking pin is provided on the outer side wall of the inner end of the inner tube, and when the telescopic assembly is in the expanded state, the locking pin is movably inserted into the locking hole to limit the axial movement of the inner tube; a push rod is fitted in the clearance inside the inner tube, the first end of the push rod is connected to the locking pin, and the second end of the push rod passes out of the outer end of the inner tube to form a protruding end; the push rod is provided with a locking pin. An elastic member is connected, and the elastic member enables the locking pin to always have a movement tendency toward the lock hole; the free end of the connecting rod is connected to a driving part that can make the locking pin disengage from the lock hole, and the driving part is configured so that when the auxiliary fitness component is in the first position or the second position, the driving part does not generate axial pressure on the protruding end of the push rod, and the locking pin is inserted into the lock hole; and when the auxiliary fitness component rotates from the first position to the second position, or from the second position to the first position, the driving part squeezes the protruding end of the push rod to cause the push rod to move axially and drive the locking pin to disengage from the lock hole. With this arrangement, when the inner tube slides axially relative to the outer tube, causing the telescopic assembly to be in the extended state, the auxiliary fitness assembly is in the extended state, that is, in the first position, and the locking pin on the inner tube is movably inserted into the locking hole on the outer tube to restrict the axial movement of the inner tube. When the auxiliary fitness assembly flips upward from the first position to the second position and remains in the second position, the locking pin on the inner tube is similarly inserted into the locking hole on the outer tube to restrict the axial movement of the inner tube, thereby preventing the telescopic assembly from accidentally retracting when the user is using the fitness bar. When the user completes training and the auxiliary fitness assembly flips downward from the second position to a certain angle but not yet to the first position, the driving unit squeezes the extended end of the push rod to cause the push rod to move axially and drive the locking pin out of the locking hole. At this time, the inner tube is pushed toward the outer tube until the locking pin is disengaged from the locking hole, and the auxiliary fitness assembly is then rotated to the first position, thereby continuing to retract the inner tube inward and retracting the auxiliary fitness assembly below the table body. The locking pin is unlocked by rotating the driving unit at the free end of the connecting rod, thereby eliminating the need for an unlocking wrench or button on the fitness bar or below the table body, thereby simplifying the structure.

[0014] Preferably, a through hole connected to the center hole and arranged radially is provided on the side wall of the inner tube, and the locking pin is loosely fitted in the through hole and can be extended or retracted into the through hole; a spring sheet is provided in the inner tube, which extends axially along the inner tube and is inclined relative to the axis of the inner tube, one end of the spring sheet is connected to the first end of the push rod, and the other end of the spring sheet is connected to the locking pin; a limiting column is connected to the inner tube, and the outer side wall of the spring sheet fits with the limiting column; when the push rod overcomes the elastic force of the elastic member to move axially and drives the spring sheet to move in the direction close to the limiting column, the spring sheet drives the locking pin to retract into the through hole, and when the push rod moves to reset under the elastic force of the elastic member, the spring sheet drives the locking pin to extend out of the through hole. With this arrangement, when the auxiliary fitness component rotates between the first position and the second position, the driving portion on the connecting rod overcomes the elastic force of the elastic member and squeezes the push rod, causing the push rod to move axially and drive the spring sheet to move in a direction close to the limit column. Due to the blocking effect of the limit column, the spring sheet contracts inward, thereby retracting the lock pin into the through hole; when the external force on the push rod disappears, or the auxiliary fitness component is in the first position or the second position, the driving portion does not generate axial pressure on the protruding end of the push rod, and the push rod is reset under the action of the elastic member, thereby causing the spring sheet to drive the lock pin to extend out of the through hole. When the lock pin is aligned with the lock hole, the lock pin can be inserted into the lock hole.

[0015] Preferably, the outer end of the inner tube is coaxially connected to a first joint, and an inner hole is provided at the center of the first joint for the protruding end of the push rod to pass through. The elastic member is arranged in the inner hole and is sleeved on the push rod. One end of the elastic member is against the inner wall of the inner hole, and the other end of the elastic member is against the limiting convex ring on the outer side wall of the protruding end of the push rod.

[0016] Preferably, the first joint is connected to a main shaft, and the outer end surface of the first joint is configured as a first plane perpendicular to the axis of the first joint; the free end of the connecting rod is coaxially connected to a second joint, the second joint is provided with a second plane perpendicular to the axis of the second joint, and the second plane is connected to a connecting block extending axially along the second joint, the connecting block is provided with an elongated hole extending axially along the second joint, and the main shaft on the first joint is loosely fitted into the elongated hole; when the second joint is rotated to a horizontal position around the axis of the main shaft, the first plane and the second plane are aligned, and the axis of the inner tube coincides with the axis of the connecting rod; the outer wall of the connecting block forms the driving portion. The provision of the elongated hole on the connecting block of the second joint can effectively prevent the second joint from interfering with the first joint during rotation, and when the second joint is rotated to a horizontal position around the axis of the main shaft, the second joint has a certain axial movable clearance relative to the first joint, thereby allowing the first plane of the first joint and the second plane of the second joint to align, thereby ensuring that the connecting rod and the telescopic rod are coaxially positioned when the auxiliary fitness component is in the first position.

[0017] Preferably, the outer diameter of the connecting rod is the same as the outer diameter of the inner tube, and when the telescopic assembly is in the retracted state, at least a portion of the connecting rod is located within the outer tube. This arrangement allows the two connecting rods on the fitness bar to be stored within the outer tube of the telescopic rod, thereby not occupying space below the table top body.

[0018] Preferably, the outer tube is provided with a positioning hole extending along its length, the positioning hole being clearance-fitted with a positioning member, the inner end of which is connected to the inner tube and moves synchronously with the inner tube; when the inner tube slides and expands relative to the outer tube until the positioning member abuts the outer end of the positioning hole, a locking pin movably engages within the locking hole of the outer tube. This arrangement facilitates quick engagement and locking of the locking pin on the inner tube with the locking hole on the outer tube when the telescopic assembly is in the expanded state.

[0019] Preferably, the outer surface of the fitness bar is covered with a soft protective layer. The soft protective layer on the fitness bar is convenient for users to perform yoga training or back muscle training, and is more comfortable when in contact with the user's muscles, so that the user has a good fitness experience.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 10 As shown;

[0034] The embodiment of the present invention discloses an electric lift fitness table, whose structure includes a table board body 1, a base 2 and a lifting assembly connecting the table board body 1 and the base 2 and capable of adjusting the height of the table board body 1 relative to the base 2; in this embodiment, the lifting assembly includes two lifting columns 3, the bottom of the table board body 1 is connected to a beam assembly, the upper ends of the two lifting columns 3 are connected to the two ends of the beam assembly, and the lower ends of the two lifting columns 3 are respectively connected to the base 2; the two lifting columns 3 are motor-driven lifting columns 3, that is, the upper end of each lifting column 3 is connected to a driving motor 300, and the driving motor 300 drives the telescopic tube of the lifting column 3 to extend to achieve height adjustment of the table board body 1; the driving motor 300, the lifting column 3 and the driving motor 300 driving the lifting column 3 to rise and fall to adjust the height of the table board body 1 are all existing mature technical means, and are not described in detail in this embodiment.

[0035] See again Figure 1 and Figure 3As shown, in this embodiment, the bottom of the table top body 1 is connected to a telescopic component 4, and the telescopic component 4 rises and falls synchronously with the table top body 1; the telescopic component 4 has two horizontally arranged telescopic rods 400 distributed along the length direction of the table top body 1, and the telescopic rods 400 can be extended and retracted along the axial direction to make the telescopic component 4 in an expanded state or a retracted state. Each telescopic rod 400 of the telescopic assembly 4 of this embodiment includes an outer tube 401 connected to the bottom of the table body 1 and an inner tube 402 slidingly fitted in the outer tube 401; the electric lifting fitness table also includes an auxiliary fitness assembly 5, which includes a fitness rod 500 extending along the length direction of the table body 1 and two connecting rods 501 connected to the fitness rod 500 and corresponding to the two telescopic rods 400 respectively. The outer diameter of the connecting rod 501 is the same as the outer diameter of the inner tube 402. When the telescopic assembly 4 is in the retracted state, at least a portion of the connecting rod 501 is retracted into the outer tube 401; the free ends of the two connecting rods 501 are respectively rotatable with the outer ends of the inner tubes 402 of the two telescopic rods 400. The rotating connection is used to rotate and switch the auxiliary fitness component 5 between the first position and the second position when the telescopic component 4 is in the expanded state; wherein, when the auxiliary fitness component 5 is in the first position, the axis of the connecting rod 501 coincides with the axis of the telescopic rod 400, and the fitness rod 500 is located below the table body 1, that is, when the auxiliary fitness component 5 is in the first position, the two connecting rods 501 are in a horizontal state, and at this time the inner tube 402 can drive the connecting rod 501 to retract into the outer tube 401; when the auxiliary fitness component 5 is in the second position, the fitness rod 500 is located above the table body 1, that is, when the auxiliary fitness component 5 is flipped upward from the first position to the second position, the fitness rod 500 of the auxiliary fitness component 5 is just above the table body 1.

[0036] In this embodiment, the bottom of the table body 1 of the electric lift fitness table is connected to an auxiliary fitness component 5 through a telescopic component 4. The telescopic rod 400 is axially extended and retracted to put the telescopic component 4 in an expanded state or a retracted state. Therefore, the auxiliary fitness component 5 can move relative to the table body 1 under the action of the telescopic component 4, so that the fitness bar 500 is pulled out or retracted into the table body 1; because the two connecting rods 501 on the fitness bar 500 can rotate relative to the outer ends of the two telescopic rods 400, and when the telescopic component 4 is in the expanded state, the fitness bar 500 can be rotated upward around its rotation axis until the fitness bar 500 is located above the table body 1. The fitness bar 500 located above the table is used for users to exercise or do yoga; in this way, when the user feels tired after working for a long time in front of the electric lift desk or during non-working hours, he can stand in front of the table body 1 and pull the auxiliary fitness component 5 out of the table body The table body 1 is flipped upwards and the auxiliary fitness component 5 is flipped upwards, so that the fitness bar 500 is flipped to the top of the table body 1, and the fitness bar 500 is used for yoga training or back muscle training or arm muscle training, etc., which can relieve work fatigue and is more conducive to efficient work; when the training is finished, the auxiliary fitness component 5 is flipped back to the first position, that is, the connecting rod 501 on the fitness bar 500 is in a horizontal state, and the telescopic component 4 is used to retract the fitness bar 500 into the table body 1, so as not to occupy the user's work space; therefore, the electric lift fitness table allows users to work and exercise properly without affecting the work of others, and its structure is simple and the setting is reasonable, which can make full use of the remaining space of the electric lift table; furthermore, the fitness bar 500 can be raised and lowered synchronously with the table body 1, so as to meet the fitness needs of users of different heights.

[0037] In this embodiment, the outer surface of the fitness bar 500 is provided with a soft protective layer; the soft protective layer on the fitness bar 500 is convenient for users to perform yoga training or back muscle training. When in contact with the user's muscles, it is more comfortable and gives the user a good fitness experience.

[0038] See also Figure 4As shown in FIG, as an embodiment of the present invention, a support frame 502 is rotatably connected to the fitness bar 500, and the support frame 502 can be rotated and switched between an unfolded position and a folded position around the axis of the fitness bar 500; the support frame 502 includes two parallel support rods, and one end of each support rod is connected to a rotating ring 503 sleeved on the fitness bar 500, the inner wall of the rotating ring 503 is provided with an inwardly convex limit block, and a limit groove for accommodating the limit block and extending along the circumference of the fitness bar 500 is provided at a corresponding position of the fitness bar 500, when the rotating ring 503 rotates around the axis of the fitness bar 500, the limit block can be rotated in the limit groove, and when the limit block abuts against the inner wall of one end of the limit groove, the support frame 502 can be in In the folded position, the plane where the support frame 502 is located coincides with or is parallel to the plane where the two connecting rods 501 are located; when the limit block is rotated to abut against the inner wall of the other end of the limit slot, the support frame 502 is in the unfolded position; and when the auxiliary fitness component 5 is rotated upward around its rotation axis to the second position and the support frame 502 is in the unfolded position, the bottom of the support frame 502 abuts against the top of the table board body 1 to support the fitness bar 500; that is, when the auxiliary fitness component 5 is rotated upward around its rotation axis until the fitness bar 500 is located above the table board body 1, the support frame 502 can be rotated open so that the lower end of the support frame 502 is supported on the table board body 1, thereby improving the load-bearing capacity of the fitness bar 500 and providing more stable support. In other embodiments, the inner wall of the rotating ring 503 may be provided with annularly distributed latching teeth, and the outer circumferential wall of the fitness bar 500 may be provided with teeth that cooperate with the latching teeth. The teeth are engaged with the latching teeth for positioning, but when the force of the circumferential rotation of the rotating ring 503 is large enough, the teeth can rotate from one latching tooth to another.

[0039] See also Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, as an embodiment of the present invention; the free end of the connecting rod 501 is rotatably connected to the outer end of the inner tube 402 through the main shaft 408; specifically, the outer end of the inner tube 402 is coaxially connected to the first joint 406, the first joint 406 is connected to the main shaft 408, the free end of the connecting rod 501 is coaxially connected to the second joint 504, the second joint 504 is connected to a connecting block extending axially along the second joint 504, the connecting block is provided with an elongated hole 505 extending axially along the second joint 504, the main shaft 408 on the first joint 406 is clearance-fitted in the elongated hole 505, for allowing the free end of the connecting rod 501 to rotate around the axis of the main shaft 408, and the second joint 504 has a certain axial movement clearance relative to the first joint 406 to avoid interference between the second joint 504 and the first joint 406 when rotating.

[0040] In this embodiment, a locking hole 403 is provided on the side of the outer tube 401 close to the fitness bar 500, and a radially slidable locking pin 604 is provided on the outer wall of the inner end of the inner tube 402. When the telescopic assembly 4 is in the expanded state, the locking pin 604 is movably inserted into the locking hole 403 to limit the axial movement of the inner tube 402; a push rod 6 is fitted into the clearance inside the inner tube 402, the first end of the push rod 6 is connected to the locking pin 604, and the second end of the push rod 6 passes outward from the outer end of the inner tube 402 and forms a protruding end 600; an elastic member 602 is connected to the push rod 6, and the elastic member 602 of this embodiment is a spring sleeved on the push rod 6; the elastic member 602 makes the locking pin 6 04 always has a movement tendency to move toward the locking hole 403; the free end of the connecting rod 501 is connected to a driving portion 506 that can disengage the locking pin 604 from the locking hole 403, and the driving portion 506 is configured so that when the auxiliary fitness component 5 is in the first position or the second position, the driving portion 506 does not generate axial pressure on the protruding end 600 of the push rod 6, and the locking pin 604 is inserted into the locking hole 403; and when the auxiliary fitness component 5 rotates from the first position to the second position, or from the second position to the first position, the driving portion 506 squeezes the protruding end 600 of the push rod 6 to cause the push rod 6 to move axially and drive the locking pin 604 to disengage from the locking hole 403. That is, when the inner tube 402 slides axially relative to the outer tube 401 to make the telescopic assembly 4 in the expanded state, the auxiliary fitness assembly 5 is in the pulled-out state, that is, the auxiliary fitness assembly 5 is in the first position, and the locking pin 604 on the inner tube 402 is movably inserted into the locking hole 403 on the outer tube 401 to limit the axial movement of the inner tube 402; when the auxiliary fitness assembly 5 flips upward from the first position to the second position and stays in the second position, the locking pin 604 on the inner tube 402 is also inserted into the locking hole 403 on the outer tube 401 to limit the axial movement of the inner tube 402. When the user uses the fitness bar 500 , effectively preventing the telescopic assembly 4 from accidentally retracting. When the user has finished exercising and the auxiliary fitness assembly 5 has tilted downward a certain angle from the second position but has not yet flipped back to the first position, the driving unit 506 squeezes the protruding end 600 of the push rod 6, causing the push rod 6 to move axially and drive the locking pin 604 out of the locking hole 403. At this time, the inner tube 402 is pushed toward the outer tube 401 until the locking pin 604 is offset from the locking hole 403, and the inner tube 402 is unlocked. The auxiliary fitness assembly 5 is then rotated to the first position, further retracting the inner tube 402 inward, retracting the auxiliary fitness assembly 5 back under the table body 1. The locking pin 604 is unlocked by rotating the driving unit 506 at the free end of the connecting rod 501, thereby eliminating the need for an unlocking wrench or button on the fitness bar 500 or under the table body 1, resulting in a simple structure.

[0041] It is easy to understand that when the telescopic assembly 4 is in the expanded state and the auxiliary fitness assembly 5 is in the first position, the locking pin 604 of the inner tube 402 is inserted into the locking hole 403 of the outer tube 401, so that the telescopic assembly 4 is in a locked state; when the auxiliary fitness assembly 5 rotates from the first position to the second position, the driving portion 506 applies axial pressure to the protruding end 600 of the push rod 6, so that the locking pin 604 can temporarily disengage from the locking hole 403. However, when the auxiliary fitness assembly 5 is in the second position, the axial pressure of the driving portion 506 on the protruding end 600 of the push rod 6 disappears, and the push rod 6 quickly returns to its original position under the elastic force of the elastic member 602, so that the locking pin 604 is quickly inserted into the locking hole 403 again, thereby locking the telescopic assembly 4; since the auxiliary fitness assembly 5 takes less time to rotate from the first position to the second position, even if the locking pin 604 temporarily disengages from the locking hole 403 during this process, it will not affect the position locking of the telescopic assembly 4.

[0042] See again Figure 6 As shown, the driving portion 506 in this embodiment refers to the outer side wall of the outer end of the connecting block. In this embodiment, the connecting block is in a rectangular parallelepiped shape, and the two edges of the outer end of the connecting block are smooth rounded transitions. When the auxiliary fitness component 5 is in the first position, the outer end surface of the connecting block contacts the protruding end 600 of the push rod 6, but does not apply pressure to the protruding end 600 of the push rod 6. Figure 8 when the auxiliary fitness assembly 5 is in the second position, the side of the connecting block contacts the protruding end 600 of the push rod 6, but does not apply pressure to the protruding end 600 of the push rod 6, as Figure 6 The state shown is shown; therefore, the portion between the outer end surface and the side surface of the connecting block can compress the protruding end 600 of the push rod 6. Therefore, when the auxiliary fitness component 5 rotates from the first position to the second position, or vice versa, the driving portion 506 of the connecting block can compress and drive the protruding end 600 of the push rod 6. To ensure that the side surface of the connecting block does not exert a force on the protruding end 600 of the push rod 6 when the auxiliary fitness component 5 is in the second position, an arc-shaped recess or arc-shaped hole 507 can be provided on the side surface of the connecting block to accommodate the protruding end 600 of the push rod 6 or to form a clearance space for the protruding end 600 of the push rod 6. Similarly, in this embodiment, the end surface of the protruding end 600 of the push rod 6 is configured to be hemispherical or arc-shaped, and the side and end surfaces of the connecting block have a smooth transition. In this embodiment, the auxiliary fitness component 5 can only flip upward from the first position and cannot rotate downward from the first position.

[0043] Furthermore, in this embodiment, an inner hole 407 is provided at the center of the first joint 406 for the protruding end 600 of the push rod 6 to pass through. An elastic member 602 is provided in the inner hole 407 and sleeved on the push rod 6. One end of the elastic member 602 abuts against the inner wall of the inner hole 407, and the other end of the elastic member 602 abuts against the limiting protrusion 601 on the outer wall of the protruding end 600 of the push rod 6. The outer end face of the first joint 406 is provided as a first plane 410 perpendicular to the axis of the first joint 406; a second plane perpendicular to the axis of the second joint 504 is provided on the second joint 504, and the connecting block is provided on the second plane. When the second joint 504 rotates to a horizontal position around the axis of the main shaft 408, the first plane 410 and the second plane fit together, and the axis of the inner tube 402 coincides with the axis of the connecting rod 501. Figure 7 and Figure 10 Status shown.

[0044] See again Figure 9 As shown in the figure, as an embodiment of the present invention; a through hole 409 is provided on the side wall of the inner tube 402 and is connected to the central hole and is arranged radially. The locking pin 604 is loosely fitted in the through hole 409 and can be extended or retracted into the through hole 409; a spring piece 603 is provided in the inner tube 402, which extends along the axial direction of the inner tube 402 and is inclined relative to the axis of the inner tube 402. One end of the spring piece 603 is connected to the first end of the push rod 6, and the other end of the spring piece 603 is connected to the lock pin 6. Pin 604 is connected; a limiting column 605 is connected inside the inner tube 402, and the outer wall of the spring piece 603 fits with the limiting column 605; when the push rod 6 overcomes the elastic force of the elastic member 602 and moves axially and drives the spring piece 603 to move toward the direction close to the limiting column 605, the spring piece 603 drives the locking pin 604 to retract into the through hole 409, and when the push rod 6 moves to reset under the elastic force of the elastic member 602, the spring piece 603 drives the locking pin 604 to extend out of the through hole 409. When the auxiliary fitness component 5 rotates between the first and second positions, the driving portion 506 on the connecting rod 501 overcomes the elastic force of the elastic member 602 and axially compresses the push rod 6, causing the push rod 6 to move axially and driving the spring 603 toward the limiting post 605. Due to the blocking effect of the limiting post 605, the spring 603 contracts inward, thereby retracting the lock pin 604 into the through hole 409. When the external force on the push rod 6 disappears, or the auxiliary fitness component 5 is in the first or second position, the driving portion 506 no longer exerts axial pressure on the protruding end 600 of the push rod 6. The push rod 6 is reset under the action of the elastic member 602, causing the spring 603 to drive the lock pin 604 out of the through hole 409. When the lock pin 604 is aligned with the lock hole 403, the lock pin 604 can be inserted into the lock hole 403. The limiting post 605 of this embodiment is a limiting post 605 that passes horizontally through the inner tube 402 and is fixedly connected to the inner tube 402 at both ends.

[0045] See again Figure 7As shown in the figure, as an embodiment of the present invention, in order to facilitate the quick insertion and locking of the locking pin 604 on the inner tube 402 and the locking hole 403 on the outer tube 401 when the telescopic assembly 4 is in the expanded state, the outer tube 401 is provided with a positioning slot 405 extending along the length of the outer tube 401. The positioning slot 405 is clearance-fitted with a positioning member 404. The inner end of the positioning member 404 is connected to the inner tube 402 and moves synchronously with the inner tube 402. When the inner tube 402 slides and expands relative to the outer tube 401 until the positioning member 404 abuts the outer end of the positioning slot 405, the locking pin 604 is movably inserted into the locking hole 403 of the outer tube 401. The positioning member in this embodiment can be a pin or a screw.
