[0032] Example 1

[0033] Reference Figures 1-4As shown, a connecting structure of an electric trolley 1 is installed between the electric trolley 1 and a driven assembly 2 arranged behind the electric trolley 1, which includes a mounting clamp seat 3 arranged on the electric trolley 1, a mounting clamp head 4 abutting against the mounting clamp seat 3, a first connecting hole 5 opened on the mounting clamp seat 3, and a second connecting hole 6 opened on the mounting clamp head 4. The first connecting hole 5 is aligned with the second connecting hole 6, and a screw 7 is screwed into the first connecting hole 5 and the second connecting hole 6. The bottom of the rod body of the electric trolley 1 is arranged on the mounting clamp seat 3, and the mounting clamp head 4 abuts against the rod body of the electric trolley 1.

[0034] The screw 7 is arranged at the first connecting hole 5 and fixed. The outer periphery of the screw 7 is integrally formed with a square clamping body. The second connecting hole 6 is a directional clamping hole. The mounting clamp head 4 is clamped between the second connecting hole 6 and the square clamping body of the outer periphery of the screw 7. The screw 7 penetrates the second connecting hole 6, and a nut 8 is screwed into the part penetrating the second connecting hole 6.

[0035] Through the cooperation of the square clamping body of the screw 7 and the directional clamping hole of the mounting clamp head 4, the loosening or slipping of the screw 7 during use can be effectively avoided. The cooperation of the square clamping body and the directional clamping hole provides better clamping effect and improves the stability of the connection, preventing the connection from loosening due to vibration or external force. The structure design of the square clamping body and the directional clamping hole simplifies the connection process. During installation, the square clamping body of the screw 7 can be accurately clamped into the directional clamping hole of the mounting clamp head 4, ensuring that the two are aligned and fixed by screwing in the nut 8. This not only reduces the dependence on complex tools, but also improves the installation efficiency, saves time and labor costs.

[0036] The cooperation structure of the square clamping body and the directional clamping hole enables the connection part to disperse and transmit pressure when subjected to external impact or vibration, enhancing the shock resistance and carrying capacity of the connection. Compared with the traditional design of circular holes and circular screws 7, the square clamping body design effectively enhances the stability and durability of the connection. The cooperation of the screw 7 and the nut 8, especially the screwing of the nut 8 after the screw 7 penetrates the second connecting hole 6, effectively enhances the firmness of the connection, preventing the connection components from loosening or damaging due to long-term use or increased load. This double fixing method ensures that the electric trolley 1 can still maintain firm connection under high load conditions.

[0037] Due to the abutting design of the mounting clamp head 4 and the bottom of the rod body of the electric trolley 1, the bottom of the rod body of the electric trolley 1 can evenly distribute pressure during use, reducing local wear and tear, and improving the durability of the connection part. Due to the fixing method of the screw 7 and the nut 8, it is more convenient to disassemble and replace the connection components. Users can disassemble by rotating the nut 8, reducing complex disassembly operations and facilitating subsequent maintenance and replacement.

[0038] Example 2

[0039] Referring to Figures 5-6 The difference between this embodiment and embodiment 1 is that a rectangular insertion slot is provided on the mounting bracket 3, the mounting clamp 4 is inserted into the rectangular insertion slot to form a clamping structure, the first connecting hole 5 penetrates through the rectangular insertion slot and is in butt joint with the second connecting hole 6, and the screw 7 is screwed into the second connecting hole 6 from the first connecting hole 5.

[0040] The mounting clamp 4 is inserted into the rectangular insertion slot to form a clamping structure, which can ensure the stability of the mounting clamp 4 in the mounting bracket 3 and prevent the clamp from slipping or rotating due to external force or vibration. This clamping design provides better mechanical locking effect, making the connection more firm and reliable; the design of the rectangular insertion slot allows the mounting clamp 4 to be accurately inserted into the bracket, reducing alignment errors during installation and improving the simplicity and efficiency of operation. At the same time, the butt joint design of the first connecting hole 5 and the second connecting hole 6 ensures the precise butt joint between the mounting clamp 4 and the electric pull rod 1, and the screw 7 is screwed into the second connecting hole 6 from the first connecting hole 5, which simplifies the installation steps and avoids complex operations and tool requirements; the clamping structure of the rectangular insertion slot can effectively disperse and bear the force transmitted by the electric pull rod 1, enhancing the anti-vibration and anti-load capacity of the connection part. This design avoids excessive wear of the connection components, especially in environments with high stress, and can provide more stable and durable connection performance, ensuring that the electric pull rod 1 can still maintain good working condition during long-term operation.

[0041] Embodiment 3

[0042] Referring to Figures 7-8 The difference between this embodiment and embodiment 1 is that one end of the screw 7 is screwed into the second connecting hole 6 for fixation, and the other end of the screw 7 penetrates through the first connecting hole 5 and is screwed with a nut 8 on the part penetrating through the first connecting hole 5.

[0043] The design of the screw 7 screwed into the second connecting hole 6 at one end and screwed with the nut 8 at the other end effectively realizes bidirectional fixation. This structure can ensure that the screw 7 is firmly fixed in place between the connection components, preventing loosening due to vibration, external force or use, and improving the long-term stability and firmness of the connection.

[0044] Screwing the screw 7 part penetrating through the first connecting hole 5 with the nut 8 can further ensure that the screw 7 is not easy to loosen. The nut 8 provides additional locking effect by applying additional locking force to the screw 7. This double locking method (screw 7 and nut 8) effectively avoids loosening caused by vibration or load changes, thereby improving the safety and reliability of the entire connection structure.

[0045] As the screw 7 is screwed into the nut 8 from the other end, only the nut 8 needs to be unscrewed during disassembly, and the screw 7 can be easily taken out. This makes maintenance and replacement of parts more convenient. Users can quickly disassemble or replace damaged components without the need for complex tools or operation steps, thereby reducing maintenance costs and time, improving system maintainability and ease of use.

[0046] Embodiment 4

[0047] Referring to Figure 1 , 2 , 9, 10, a connecting structure of an electric trolley 1 is installed between the electric trolley 1 and a driven assembly 2 arranged at the rear of the electric trolley 1, comprising a mounting seat 3 arranged on the electric trolley 1, a mounting chuck 4 abutting against the mounting seat 3, a first connecting hole 5 opened on the mounting seat 3, and a second connecting hole 6 opened on the mounting chuck 4. The first connecting hole 5 and the second connecting hole 6 are aligned and screwed with a screw 7 for fixation. The bottom of the shaft of the electric trolley 1 is arranged on the mounting seat 3, and the mounting chuck 4 forms a hoop around the shaft of the electric trolley 1.

[0048] The mounting seat 3 is provided with a mounting slot, and the mounting chuck 4 is inserted into the mounting slot. The first connecting hole 5 penetrates the mounting slot and is connected to the second connecting hole 6.

[0049] The mounting chuck 4 is fixed by being inserted into the mounting slot and connected to the first connecting hole 5 and the second connecting hole 6 on the mounting seat 3, ensuring that the connection between the electric trolley 1 and the driven assembly 2 is more stable and firm. The screw 7 tightly combines the first connecting hole 5 and the second connecting hole 6, avoiding loosening or falling off caused by external force or vibration, thereby improving the safety and reliability of the system.

[0050] The design of the mounting chuck 4 inserted into the slot simplifies the installation process and makes the alignment more accurate. The connection part of the electric trolley 1 and the driven assembly 2 can be easily connected during the installation process, reducing the installation time and operation difficulty. In addition, the matching of the chuck and the slot can ensure the correct connection of the components, avoiding human operation errors.

[0051] The mounting chuck 4 forms a hoop around the shaft of the electric trolley 1, enhancing the connection strength between the electric trolley 1 and the seat. This hoop structure effectively disperses the pressure generated during the use of the electric trolley 1, reducing the risk of damage caused by uneven local stress. Combined with the locking effect of the screw 7, the connection part can withstand greater force, thereby improving the overall mechanical strength and durability of the structure.

[0052] Embodiment 5

[0053] Referring to Figures 11-12As shown, the difference between this embodiment and embodiment 4 is that the mounting seat 3 is provided with a mounting stop, the mounting head 4 abuts against the mounting stop, the screw 7 is fixed at the first connecting hole 5, the screw 7 penetrates the second connecting hole 6, and the portion penetrating the second connecting hole 6 is screwed with a nut 8.

[0054] The design of the mounting head 4 abutting against the mounting stop ensures the precise butt joint between the head and the seat, avoiding installation errors and unstable connection. The first connecting hole 5 and the second connecting hole 6 are fixed by the screw 7, and the screw 7 penetrates the second connecting hole 6 and is locked by the nut 8, so that the double fixing mode can effectively prevent the screw 7 from loosening and enhance the stability of the connection.

[0055] The design of locking by the nut 8 not only fixes the connecting hole by screwing, but also further prevents the screw 7 from loosening by the additional tightening force of the nut 8. This anti-loosening design is particularly suitable for dynamic load conditions such as vibration and impact, ensuring the stability and safety of the connection during long-term operation.

[0056] The design of the screw 7 and the nut 8 enables the connection structure to be easily disassembled and maintained. When disassembly is required, the screw 7 can be easily removed by loosening the nut 8, and the disassembly operation can be quickly completed, reducing the complexity and time cost during maintenance. At the same time, this connection structure does not require special tools, which can improve the maintenance efficiency.

[0057] The above embodiments of the present application are not a limitation of the protection scope of the present application, and the implementation manner of the present application is not limited thereto. According to the above content of the present application, according to the ordinary technical knowledge and common means in the art, other various forms of modifications, replacements or changes to the above structure of the present application without departing from the above basic technical idea of the present application should fall within the protection scope of the present application.
