Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and in particular to a double-pole folding mechanism and an electric scooter. Background Technology

[0002] With the increasing severity of urban traffic congestion and people's growing pursuit of convenient travel options, electric scooters have gained widespread attention due to their compact size, flexibility, and portability. Currently, electric scooter stands on the market typically use a single-stick design or connect two sticks through a relatively complex mechanical structure.

[0003] The existing connection methods for the poles mainly include welding and bolt fixing. Although welding provides a more secure connection, it fixes the overall structure of the electric scooter, preventing it from folding and greatly affecting its portability. Bolting allows for partial folding to some extent, but the operation is cumbersome, and the connection points are prone to loosening, affecting safety and stability during use.

[0004] Furthermore, the shortcomings of existing poles are also reflected in the following aspects: On the one hand, electric scooters with a single pole design are relatively unstable and prone to tipping; on the other hand, the existing connection method cannot meet users' needs for quick folding and unfolding, and takes up a lot of space when carrying and storing, causing many inconveniences for users. In summary, there is currently a lack of a folding structure in electric scooters that can simultaneously and detachably connect two poles. Utility Model Content

[0005] The main purpose of this utility model is to provide a double-pole folding mechanism and an electric scooter, aiming to solve the technical problem that the current electric scooter lacks a folding structure that can detachably connect two poles at the same time, resulting in a complex connection structure and a large space occupation when carrying and storing the electric scooter.

[0006] To achieve the above-mentioned utility model objectives, this utility model proposes a double-pole folding mechanism, including a first pole, a second pole, a sliding sleeve, a locking mechanism, a first connecting member, and a second connecting member;

[0007] The second connector is rotatably connected to the first upright, the second upright, and the first connector;

[0008] The first upright and the second upright are slidably sleeved in the sliding sleeve, and the first upright and the second upright are separably sleeved on the first connecting member through the sliding sleeve;

[0009] The locking mechanism is rotatably mounted on the sliding sleeve. The locking mechanism is used to control the sliding sleeve to clamp or release the first upright and the second upright, so that the first upright and the second upright are detachably connected to the first connecting member, and the first upright and the second upright rotate and fold relative to the second connecting member.

[0010] Furthermore, the sliding sleeve is provided with a first space that cooperates with the first upright, a second space that cooperates with the second upright, and a third space that communicates with the first space and the second space respectively. The first upright is slidably fitted in the first space, the second upright is slidably fitted in the second space, and the locking mechanism is provided on the sliding sleeve and corresponds to the third space.

[0011] Furthermore, the locking mechanism is rotatably connected to the side of the sliding sleeve away from the second connecting member via a pull rod. The locking mechanism is provided with a protrusion, and when the sliding sleeve is in a clamped state, the protrusion contacts the sliding sleeve, and when the sliding sleeve is in a released state, the protrusion separates from the sliding sleeve.

[0012] Furthermore, the double-pole folding mechanism also includes a first movable member, a second movable member, a first elastic member, and a second elastic member. The first pole and the second pole are respectively provided with a first cavity and a second cavity. The first movable member and the first elastic member, and the second movable member and the second elastic member are respectively movably disposed in the first cavity and the second cavity, so that the first movable member and the second movable member move in the first pole and the second pole respectively under the action of the first elastic member and the second elastic member.

[0013] Furthermore, the double-pole folding mechanism also includes a first sliding sleeve fixing member and a second sliding sleeve fixing member. The sliding sleeve is provided with a first sliding sleeve fixing member slot and a second sliding sleeve fixing member slot. The first sliding sleeve fixing member and the second sliding sleeve fixing member respectively pass through the first sliding sleeve fixing member slot and the second sliding sleeve fixing member slot and are connected to the first movable member and the second movable member. The first pole and the second pole are respectively provided with a first sliding groove and a second sliding groove. The first sliding sleeve fixing member and the second sliding sleeve fixing member are respectively movably disposed in the first sliding groove and the second sliding groove.

[0014] Furthermore, the first connector is provided with a first connecting part and a second connecting part that cooperate with the sliding sleeve at one end near the first upright and the second upright. The first space and the second space of the sliding sleeve are respectively separably sleeved on the first connecting part and the second connecting part, and the first movable member and the second movable member are respectively movably connected in the first connecting part and the second connecting part.

[0015] Furthermore, the first slide groove and the second slide groove are respectively provided with a first slide groove notch and a second slide groove notch at the ends away from the first connecting part and the second connecting part, the angle between the first slide groove notch and the first slide groove is greater than or equal to 90°, and the angle between the second slide groove notch and the second slide groove is greater than or equal to 90°.

[0016] Furthermore, the double-pole folding mechanism also includes a blocking device, which is a telescopic structure. The blocking device is located on the sliding sleeve near the third space and corresponds to the locking mechanism. The rotation of the locking mechanism is controlled by the telescopic movement of the blocking device.

[0017] Furthermore, the locking mechanism is provided with a cam structure. When the locking mechanism rotates to the first position, the cam structure presses the sliding sleeve, causing the sliding sleeve to clamp the first upright and the second upright. When the locking mechanism rotates to the second position, the cam structure releases the sliding sleeve, causing the sliding sleeve to release the first upright and the second upright.

[0018] This utility model also proposes an electric scooter, including the double-pole folding mechanism described in any of the above embodiments.

[0019] Beneficial effects:

[0020] This utility model discloses a double-pole folding mechanism, comprising a first pole, a second pole, a sliding sleeve, a locking mechanism, a first connector, and a second connector. The second connector is rotatably connected to the first pole, the second pole, and the first connector. The first pole and the second pole are simultaneously slidably fitted into the sliding sleeve, and the first pole and the second pole are detachably fitted onto the first connector via the sliding sleeve. The locking mechanism is rotatably mounted on the sliding sleeve, and the locking mechanism is used to control the sliding sleeve to clamp or release the first pole and the second pole, so that the first pole and the second pole are detachably connected to the first connector, and the first pole and the second pole are detachably connected. The pole rotates and folds relative to the second connector. Therefore, by setting a sliding sleeve to simultaneously release or clamp the first and second poles, a detachable connection with the first connector is achieved. The rotation, folding, and locking of the first and second poles with the second connector are also achieved. This allows users to easily fold and lock the poles using the design of the sliding sleeve and locking mechanism, without complicated operating steps, thus improving ease of use. In the folded state, the locking mechanism ensures that the poles are firmly fixed in place, preventing accidental loosening or unfolding during carrying or transportation, thus improving safety. At the same time, the folded poles occupy little space, making them easy to store in environments with limited space, such as homes and offices, and also convenient to carry on public transportation.

[0038] Reference Figures 1-10 This embodiment provides a double-pole folding mechanism, including a first pole 1, a second pole 2, a sliding sleeve 3, a locking mechanism 4, a first connecting member 5, and a second connecting member 6;

[0039] The second connector 6 is rotatably connected to the first upright 1, the second upright 2 and the first connector 5;

[0040] The first upright 1 and the second upright 2 are simultaneously slidably sleeved in the sliding sleeve 3, and the first upright 1 and the second upright 2 are separably sleeved on the first connecting member 5 through the sliding sleeve 3;

[0041] The locking mechanism 4 is rotatably mounted on the sliding sleeve 3. The locking mechanism 4 is used to control the sliding sleeve 3 to clamp or release the first upright 1 and the second upright 2, so that the first upright 1 and the second upright 2 are detachably connected to the first connecting member 5, and the first upright 1 and the second upright 2 are rotated and folded relative to the second connecting member 6.

[0042] In the above embodiment, the double-pole folding mechanism includes a first pole 1, a second pole 2, a sliding sleeve 3, a locking mechanism 4, a first connecting member 5, and a second connecting member 6. The first pole 1 and the second pole 2 are important support structures for the electric scooter, similar to the frame of a bicycle, providing vertical support for the entire scooter and serving as the base for mounting handlebars and other components. The sliding sleeve 3 is a component fitted over the first pole 1 and the second pole 2, with an inner diameter slightly larger than the outer diameter of the poles, allowing the poles to slide smoothly within the sleeve. It also plays a crucial role in connecting the poles and the first connecting member 5. The locking mechanism 4 is a wrench-like device mounted on the sliding sleeve 3 and can be used to lock the poles around the sliding sleeve 6. A shaft rotates, and its main function is to change the inner diameter of the sliding sleeve 3 by rotating itself, thereby realizing the clamping or loosening operation of the first upright 1 and the second upright 2. The first connecting part 5 (front wheel assembly) is the front wheel part of the electric scooter and the related connecting structure. It includes the front wheel, the front fork and other parts used to connect the front wheel and the scooter body. It is a key component for the scooter to achieve steering and partial support functions. The second connecting part 6 (pedal assembly and related) consists of the pedal assembly and the rear wheel assembly connected to the pedal assembly and corresponding to the front wheel assembly. The pedal assembly is where the user stands and operates the scooter, while the rear wheel assembly and the front wheel assembly jointly undertake the support and driving functions of the scooter.

[0043] The first upright 1 and the second upright 2 are slidably fitted into the sliding sleeve 3, and are detachably connected to the first connecting member 5 (front wheel assembly) via the sliding sleeve 3. This allows the uprights to move relative to the front wheel assembly to a certain extent, facilitating the folding and unfolding of the scooter. The second connecting member 6 (pedal assembly and related components) is connected to the first upright 1, the second upright 2, and the first connecting member 5 via the upright connecting member 25. Specifically, the second connecting member 6 is rotatably connected to the first upright 1 and the second upright 2 on the upright connecting member 25, allowing the pedal assembly to rotate relative to the uprights. Simultaneously, the second connecting member 6 is also connected to the first connecting member 5 (front wheel assembly) via the upright connecting member 25, and this connection also allows for a certain degree of rotational movement. The first upright 1 and the second upright 2 are rotatably connected to the end of the upright connecting member 25 away from the first connecting member 5, and the planes formed by their rotation are perpendicular to each other, making the first upright 1 and the second upright 2... The two uprights 2 can be folded relative to the first connecting member 5 (front wheel assembly) and the second connecting member 6 (pedal assembly and related components), thereby greatly reducing the space occupied by the scooter when not in use. Therefore, users can easily fold and unfold the first uprights 1 and the second uprights 2 by simply operating the locking mechanism 4. Compared with the traditional complex folding structure, this design greatly improves the convenience of user operation. Whether it is necessary to frequently fold the scooter for carrying in daily use or to save space when storing the scooter, the operation can be completed quickly and conveniently. Furthermore, since the first uprights 1 and the second uprights 2 can be folded relative to the first connecting member 5 and the second connecting member 6, the folded structure is compact, greatly reducing the space occupied by the scooter when not in use. At the same time, in the folded state, the locking mechanism 4 can ensure that the first uprights 1 and the second uprights 2 are firmly fixed in place, preventing accidental loosening or unfolding during carrying or transportation.

[0044] Reference Figures 1-8 In one embodiment, the sliding sleeve 3 is provided with a first space 22 that cooperates with the first upright 1, a second space 23 that cooperates with the second upright 2, and a third space 24 that communicates with the first space 22 and the second space 23 respectively. The first upright 1 is slidably fitted in the first space 22, and the second upright 2 is slidably fitted in the second space 23. The locking mechanism 4 is provided on the sliding sleeve 3 and corresponds to the third space 24.

[0045] In the above embodiment, the sliding sleeve 3 is provided with a first space 22, a second space 23, and a third space 24. The first space 22 is specifically designed to cooperate with the first upright 1, and its shape and size are adapted to the first upright 1, allowing the first upright 1 to slide smoothly within it. The second space 23 is a space tailored for the second upright 2, ensuring that the second upright 2 can be slidably fitted within it. The third space 24 is located between the first space 22 and the second space 23, and the third space 24 connects the first space 22 and the second space 23, providing convenience for the operation of the entire structure. The locking mechanism 4 is provided on the sliding sleeve 3 and corresponds to the third space 24, and is used to control the clamping or loosening of the sliding sleeve 3 on the first upright 1 and the second upright 2. The first upright 1 is located in the first space 22 of the sliding sleeve 3, and the second upright 2 is located in the second space 23. The two are defined in relative position and slidably connected by the sliding sleeve 3. The locking mechanism 4, positioned on the sliding sleeve 3 corresponding to the third space 24, indirectly affects the clamping or loosening state of the uprights in the first space 22 and the second space 23 by acting on the related structures of the third space 24. As the locking mechanism 4 moves, it acts on the related structures of the third space 24, thereby reducing the inner diameter of the first space 22 and the second space 23 of the sliding sleeve 3, thus clamping the first upright 1 and the second upright 2. The reverse movement of the locking mechanism 4 changes the related structures of the third space 24, increasing the inner diameter of the first space 22 and the second space 23 of the sliding sleeve 3, allowing the first upright 1 and the second upright 2 to loosen and slide freely within their respective spaces. The first space 22 and the second space 23 provide precise positioning for the first upright 1 and the second upright 2, ensuring the stability and accuracy of the uprights sliding within the sliding sleeve 3, reducing swaying and offset, and improving the reliability of the entire structure.

[0046] Reference Figures 1-8 In one embodiment, the locking mechanism 4 is rotatably connected to the side of the sliding sleeve 3 away from the second connecting member 6 via a pull rod 42. The locking mechanism 4 is provided with a protrusion 43. When the sliding sleeve 3 is in a clamped state, the protrusion 43 is in contact with the sliding sleeve 3. When the sliding sleeve 3 is in a loosened state, the protrusion 43 is separated from the sliding sleeve 3.

[0047] In the above embodiment, the locking mechanism 4 includes a wrench 40 and a support member 41. The wrench 40 is part of the locking mechanism 4 and is rotatably connected to the support member 41 via a pull rod 42, allowing it to rotate around an axis. The support member 41 is located on the side of the sliding sleeve 3 away from the second connecting member 6, providing support and a base for the wrench 40 to rotate. The pull rod 42 connects the wrench 40 and the support member 41, enabling the wrench 40 to rotate around the support member 41. A protrusion 43 is located at the end of the wrench 40 near the support member 41, contacting or separating from the sliding sleeve 3 to achieve different states. The support member 41 is fixed on the side of the sliding sleeve 3 away from the second connecting member 6. The wrench 40 is rotatably connected to the support member 41 via the pull rod 42 and is located near the sliding sleeve 3. The protrusion 43 is located on the wrench 40 near the support member. When the wrench 40 is operated, the position of the wrench 41 changes its contact state with the sliding sleeve 3, thereby controlling the clamping or loosening of the sliding sleeve 3. Hold the end of the wrench 40 away from the protrusion 43 and rotate the wrench 40 towards the sliding sleeve 3. As the wrench 40 rotates, the protrusion 43 gradually approaches the sliding sleeve 3 until it contacts the sliding sleeve 3. At this time, the sliding sleeve 3 is subjected to the pressure of the protrusion 43, and its inner diameter becomes smaller, clamping the first upright 1 and the second upright 2. The loosening operation is the opposite. The clamping and loosening of the sliding sleeve 3 can be achieved by rotating the wrench 40. The operation is simple and intuitive, and users can easily master it. The contact design between the protrusion 43 and the sliding sleeve 3 ensures that a stable clamping force can be provided in the clamping state, so that the first upright 1 and the second upright 2 are firmly fixed.

[0048] Reference Figures 1-8 In one embodiment, the locking mechanism 4 is provided with a cam structure. When the locking mechanism 4 rotates to the first position, the cam structure presses the sliding sleeve 3, causing the sliding sleeve 3 to clamp the first upright 1 and the second upright 2. When the locking mechanism 4 rotates to the second position, the cam structure releases the sliding sleeve 3, causing the sliding sleeve 3 to release the first upright 1 and the second upright 2.

[0049] In the above embodiments, the locking mechanism 4 is provided with a cam structure, wherein the cam structure is a component with a curved profile. As another embodiment of the wrench 40, it is not shown in the drawings. The locking mechanism 4 is installed on the sliding sleeve 3, and the cam structure is located on the locking mechanism 4. The sliding sleeve 3 is located outside the first upright 1 and the second upright 2. The upright is clamped or released by the operation of the locking mechanism 4. The locking mechanism 4 is located in a suitable position on the sliding sleeve 3 so as to effectively control the clamping and releasing action of the sliding sleeve 3. When the locking mechanism 4 is rotated to different positions, it can produce a corresponding action with the sliding sleeve 3, that is, to press or release the sliding sleeve. Through the cooperation of the cam structure and the sliding sleeve 3, the user only needs to rotate the locking mechanism to the corresponding position to easily clamp or release the upright. The operation is simple and convenient, without complicated tools or operating steps. When it is necessary to fold the electric scooter, the locking mechanism 4 is rotated to the second position, the cam structure releases the sliding sleeve 3, and the sliding sleeve 3 releases the first upright 1 and the second upright 2, so that the upright can be rotated and folded, reducing the space occupied by the scooter and making it easy to carry and store.

[0050] When the locking mechanism 4 rotates to the first position, during the rotation, the cam structure on the locking mechanism 4 gradually approaches the sliding sleeve. The cam structure presses against the sliding sleeve, and due to the special shape of the cam structure, it applies an inward pressure to the sliding sleeve 3, making the inner diameter of the sliding sleeve 3 smaller, thereby clamping the first upright 1 and the second upright 2. At this time, the friction between the first upright 1 and the second upright 2 and the sliding sleeve 3 increases, and they are firmly fixed together, achieving a stable connection and providing a reliable support structure for the electric scooter. When the locking mechanism 4 rotates to the second position, during the rotation, the cam structure gradually moves away from the sliding sleeve 3, and the pressure on the sliding sleeve 3 gradually decreases. The cam structure completely releases the sliding sleeve 3, and the inner diameter of the sliding sleeve 3 returns to its initial state (or close to its initial state). The first upright 1 and the second upright 2 can slide freely inside the sliding sleeve 3, thereby releasing the uprights and facilitating subsequent folding operations.

[0051] Reference Figures 1-8 In one embodiment, the double-pole folding mechanism further includes a first movable member 7, a second movable member 8, a first elastic member 9, and a second elastic member 10. The first pole 1 and the second pole 2 are respectively provided with a first cavity and a second cavity. The first movable member 7 and the first elastic member 9, and the second movable member 8 and the second elastic member 10 are respectively movably disposed in the first cavity and the second cavity, so that the first movable member 7 and the second movable member 8 move in the first pole 1 and the second pole 2 respectively under the action of the first elastic member 9 and the second elastic member 10.

[0052] In the above embodiment, the double-pole folding mechanism further includes a first movable member 7, a second movable member 8, a first elastic member 9, and a second elastic member 10. The first movable member 7 and the second movable member 8 are components that can move within the upright cavity, and their shape and size are adapted to the upright cavity. The first elastic member 9 and the second elastic member 10 are typically made of elastic materials such as springs, providing elasticity to the movable members. The first cavity and the second cavity are located inside the first upright 1 and the second upright 2, respectively, providing accommodating space for the movable members and the elastic members. The first movable member 7 and the first elastic member 9 are disposed within the first cavity of the first upright 1, and the second movable member 8 and the second elastic member 10 are disposed within the second cavity of the second upright 2. The movable members, in their elastic... Under the action of the components, the first movable component 7 can move within the cavity. When the upright is in the unfolded state, the first movable component 7 moves towards the connection part under the elastic force of the first elastic component 9, making close contact with the connecting parts. The second movable component 8 moves in the same way under the action of the second elastic component 10, enhancing the connection stability. If an external force causes the upright to have a displacement tendency, the connection part will exert pressure on the movable component. Under the action of pressure, the first movable component 7 overcomes the elastic force of the first elastic component 9 and moves accordingly within the first cavity. The second movable component 8 moves in the same way. Through the buffer of the elastic component, the overall structure is protected. When the upright is unfolded and in use, the movable component makes close contact with other connecting parts under the action of the elastic component, enhancing the stability of the connection between the upright and other parts and reducing shaking.

[0053] Reference Figures 1-8 In one embodiment, the double-pole folding mechanism further includes a first sliding sleeve fixing member 11 and a second sliding sleeve fixing member 12. The sliding sleeve 3 is provided with a first sliding sleeve fixing member slot 13 and a second sliding sleeve fixing member slot 14. The first sliding sleeve fixing member 11 and the second sliding sleeve fixing member 12 pass through the first sliding sleeve fixing member slot 13 and the second sliding sleeve fixing member slot 14 respectively and are connected to the first movable member 7 and the second movable member 8. The first pole 1 and the second pole 2 are respectively provided with a first sliding groove 15 and a second sliding groove 16. The first sliding sleeve fixing member 11 and the second sliding sleeve fixing member 12 are respectively movably disposed in the first sliding groove 15 and the second sliding groove 16.

[0054] In the above embodiment, the double-pole folding mechanism further includes a first sliding sleeve fixing member 11 and a second sliding sleeve fixing member 12. The first sliding sleeve fixing member 11 and the second sliding sleeve fixing member 12 are used to connect the sliding sleeve 3 and the movable member, and are components that move within the sliding groove. The first sliding sleeve fixing member slot 13 and the second sliding sleeve fixing member slot 14 are located on the sliding sleeve 3, providing openings for the sliding sleeve 3 fixing member to pass through. The first sliding groove 15 and the second sliding groove 16 are respectively on the first upright 1 and the second upright 2, providing movement space for the sliding sleeve 3 fixing member. The first sliding sleeve fixing member 11 passes through the first sliding sleeve fixing member slot 13 and connects to the first movable member 7, and can move within the first sliding groove 15 of the first upright 1. The second sliding sleeve fixing member 12 is similarly connected through the first sliding sleeve fixing member slot 13. The second sliding sleeve 3 is connected to the second movable part 8 through the second sliding sleeve fixing slot 14 and moves within the second sliding groove 16 of the second upright 2. When folding, the sliding sleeve 3 fixing part moves with the movable part in the sliding groove, maintaining the connection. At the same time, the sliding sleeve 3 fixing part passes through the slot, so that the sliding sleeve 3 and the movable part move together to realize the folding of the upright. When unfolding, the sliding sleeve 3 fixing part moves in the opposite direction in the sliding groove, driving the movable part, so that the sliding sleeve 3 and the movable part return to the unfolded position, ensuring structural stability. The sliding sleeve 3 fixing part connects the movable part to the sliding sleeve 3, making the overall structure more tightly connected and reducing loosening. The sliding groove provides a guide for the sliding sleeve 3 fixing part, ensuring the accuracy and stability of its movement, which is beneficial to folding and unfolding operations.

[0055] Reference Figures 1-10 In one embodiment, the first connecting member 5 is provided with a first connecting part 17 and a second connecting part 18 that cooperate with the sliding sleeve 3 at one end near the first upright 1 and the second upright 2. The first space 22 and the second space 23 of the sliding sleeve 3 are respectively separably sleeved on the first connecting part 17 and the second connecting part 18, and the first movable member 7 and the second movable member 8 are respectively movably connected in the first connecting part 17 and the second connecting part 18.

[0056] In the above embodiment, the first connecting part 17 and the second connecting part 18 are provided in a specific structure near one end of the first connecting member 5, close to the first upright 1 and the second upright 2, for establishing a connection with the sliding sleeve 3 and the movable part. The first sliding groove 15 and the second sliding groove 16 are respectively located on the elongated structures on the first upright 1 and the second upright 2, providing movement space for related components. The first space 22 and the second space 23 of the sliding sleeve 3 are respectively fitted onto the first connecting part 17 and the second connecting part 18. This fitting is separable and facilitates folding operation. The first movable part 7 and the second movable part 8 are respectively located on the first connecting part 17 and the second connecting part 18. The movable connection within part 17 and the second connecting part 18 enhances the stability of the connection. The length design of the first sliding groove 15 and the second sliding groove 16 is crucial; it is greater than or equal to the depth of the sliding sleeve 3 entering the first connecting part 17 and the second connecting part 18, ensuring that the uprights can move smoothly during folding without being obstructed by the sliding sleeve 3 and the connecting part. During folding, confirm that the locking mechanism 4 is in the released state. At this time, the sliding sleeve 3 has no clamping force on the first upright 1 and the second upright 2. Then, hold the first upright 1 and the second upright 2 and rotate them around the connection point with the first connecting member 5 in the folding direction. Since the length of the first sliding groove 15 and the second sliding groove 16 is sufficient, the sliding sleeve 3 will not obstruct the rotation, and the uprights can be folded smoothly. During the folding process, the first movable member 7 and the second movable member 8 will move accordingly within the first connecting part 17 and the second connecting part 18, maintaining the connection relationship with each component. The fitting of the sliding sleeve 3 with the first connecting part 17 and the second connecting part 18, as well as the connection of the movable members, forms a stable connection structure between the first upright 1 and the second upright 2 and the first connecting member 5. This connection method allows the electric scooter to withstand various forces during use, ensuring the stability and safety of the overall structure.

[0057] Reference Figures 1-8 In one embodiment, the first slide groove 15 and the second slide groove 16 are respectively provided with a first slide groove slot 19 and a second slide groove slot 20 at the ends away from the first connecting portion 17 and the second connecting portion 18. The angle between the first slide groove slot 19 and the first slide groove 15 is greater than or equal to 90°, and the angle between the second slide groove slot 20 and the second slide groove 16 is greater than or equal to 90°.

[0058] In the above embodiment, the first slide groove 15 and the second slide groove 16 are elongated groove structures on the first upright 1 and the second upright 2, providing movable space for the sliding sleeve 3 fixing member. The first slide groove latch 19 and the second slide groove latch 20 are respectively provided in the opening structure at the end of the first slide groove 15 and the second slide groove 16 away from the connecting part. The first slide groove 15 and the second slide groove 16 cooperate with the sliding sleeve 3 fixing member, and the sliding sleeve 3 fixing member can move within it. The first slide groove latch 19 and the second slide groove latch 20 are located at the end of the slide groove and form a specific angle with the slide groove, so as to slide the slide... Insert the sleeve 3 fastener along the first slide groove 15 or the second slide groove 16 until the sleeve 3 fastener reaches the bayonet position. Due to the angle design of the bayonet and the slide groove, the sleeve 3 fastener can be smoothly inserted into the bayonet to complete the installation. Apply appropriate external force to make the sleeve 3 fastener overcome the bayonet restriction and disengage from the bayonet. Then, move the sleeve 3 fastener along the slide groove to complete the disassembly. The large angle bayonet design allows the sleeve 3 fastener to be effectively locked when it is far away from the connecting part, which enhances the stability of the structure and prevents the sleeve 3 fastener from accidentally sliding during use.

[0059] Reference Figures 1-8 In one embodiment, the double-pole folding mechanism further includes a blocking device 21, which is a telescopic structure. The blocking device 21 is located on the sliding sleeve 3 near the third space 24 and corresponds to the locking mechanism 4. The rotation of the locking mechanism 4 is controlled by the telescopic movement of the blocking device 21.

[0060] In the above embodiment, the blocking device 21 is a retractable structure used to control the rotation of the locking mechanism 4. The locking mechanism 4 is used to control the clamping or loosening of the sliding sleeve 3 on the upright. The blocking device 21 is located near the third space 24 of the sliding sleeve 3 and corresponds to the locking mechanism 4. The blocking device 21 is spatially closely related to the sliding sleeve 3 and the locking mechanism 4. It affects the rotation of the locking mechanism 4 through its own telescopic movement. When it is necessary to lock the upright, first ensure that the blocking device 21 is in a retracted state so as not to obstruct the rotation of the locking mechanism 4. Then operate the locking mechanism 4 to rotate it to the position of clamping the sliding sleeve 3, thereby clamping the upright. When it is necessary to unlock the upright, first retract the blocking device 21 so that the locking mechanism 4 can be operated. Operate the locking mechanism 4 to rotate it to the position of releasing the sliding sleeve 3 to complete the unlocking. At the same time, when it is not necessary to operate the locking mechanism 4, the blocking device 21 can be extended to prevent it from rotating accidentally. The presence of the blocking device 21 can effectively prevent the locking mechanism 4 from being rotated accidentally, thereby avoiding the sliding sleeve 3 from accidentally loosening or clamping the upright during use, improving the safety and stability of use.
