[0029] 300. Vehicle body. Detailed Implementation

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0031] This embodiment of a movable railing for a vehicle body relates to the field of rail work platform vehicle technology. By setting a stable and detachable structure between the railing and the vehicle body 300, the railing can be disassembled when necessary, facilitating the up-and-down movement of engineering machinery and personnel.

[0032] Please see Figures 1 to 8 The movable guardrail of the vehicle body in this embodiment includes: a guardrail body 100 and a plurality of connecting components 200. The guardrail body 100 includes a plurality of connectors 110. Each connector 110 is detachably connected to the vehicle body 300 through the connecting component 200, which can realize simple assembly and disassembly of the guardrail.

[0033] The connecting assembly 200 includes a first connecting unit 210, a connecting seat 220, and a connecting sleeve 230. The first connecting unit 210 is disposed on the connecting head 110, and the connecting seat 220 is used to connect with the vehicle body 300. The first connecting unit 210 includes an abutment ring 211 disposed on the connecting head 110. The connecting head 110 is movably inserted into the connecting seat 220, and the connecting sleeve 230 is slidably sleeved on the connecting head 110. The inner wall of the connecting sleeve 230 is threadedly connected to the outer wall of the connecting seat 220. The two ends of the abutment ring 211 abut against the ends of the connecting seat 220 and the connecting sleeve 230, respectively. The connecting sleeve 230 can lock the abutment ring 211 in the axial space between the connecting sleeve 230 and the connecting seat 220.

[0034] The threaded connection system of the abutment ring 211, connecting sleeve 230, and connecting seat 220 ensures that the guardrail will not loosen during normal operation, thus guaranteeing the safety of the workers. The guardrail can be quickly detached from the vehicle body 300 when necessary, reducing the operational difficulty and time required when operating the work platform.

[0035] During use, multiple connectors 110 are inserted into multiple connector seats 220, so that the bottom of the abutment ring 211 abuts against the connector seat 220. Then, the connecting sleeve 230 is rotated so that the connecting sleeve 230 is threadedly connected to the connector seat 220, and the two ends of the abutment ring 211 abut against the ends of the connector seat 220 and the connecting sleeve 230 respectively, thus fixing the connector 110. By rotating the connecting sleeve 230 in the opposite direction, the connector 110 can be removed from the vehicle body 300, thus completing the disassembly of the railing.

[0036] In some embodiments, please refer to Figures 2 to 4The upper end of the connecting sleeve 230 is provided with a flange 231 extending inward. The flange 231 abuts against the upper end of the abutment ring 211, which can effectively enhance the fixed connection between the connecting sleeve 230 and the connector 110 (especially the abutment ring 211 on the connector 110). Through contact with the abutment ring 211, the flange 231 prevents the connecting sleeve 230 from loosening or falling off due to vibration or external force during use, thereby improving the tensile strength and impact resistance of the entire railing structure.

[0037] It should be noted that the outer diameter of the abutment ring 211 is larger than the outer diameter of the connector 110, and the inner diameter of the flange 231 is smaller than the outer diameter of the abutment ring 211. The end of the flange 231 can act on the end of the abutment ring 211. The connecting sleeve 230 is pre-installed on the connector 110 during the railing welding process, and the abutment ring 211 can prevent the connecting sleeve 230 from falling off the connector 110.

[0038] In some embodiments, please refer to Figure 2 and Figure 3 The connecting seat 220 includes a base 221 and a connecting cylinder 222. The base 221 can be detachably connected to the vehicle body 300 by means of a screw. The connecting cylinder 222 is set perpendicular to the base 221 and is integrally connected to the base 221. The connecting head 110 is movably inserted into the connecting cylinder 222. The inner wall of the connecting sleeve 230 is threadedly connected to the outer wall of the connecting cylinder 222.

[0039] The base 221 is detachably connected to the vehicle body 300. The railings can be installed or removed according to the work requirements. They do not need to be fixed to the platform for a long time. When moving engineering equipment or personnel to and from the platform, the railings can be quickly removed to provide a larger working space.

[0040] The connector 110 is movably inserted into the connecting cylinder 222, allowing the railing to be freely inserted or removed from the connecting cylinder 222 for quick assembly and disassembly. The inner wall of the connecting sleeve 230 is threaded to the outer wall of the connecting cylinder 222. This threaded connection structure makes the railing more secure after installation and less prone to loosening during operation. Simultaneously, the threaded connection provides an adjustable tightening effect, allowing the locking force of the railing to be adjusted as needed.

[0041] In some embodiments, please refer to Figure 2 , Figure 5 and Figure 7 The connecting assembly 200 also includes a snap-fit ​​unit 240, which includes at least one snap-fit ​​body 241 and a slot 242 adapted to the snap-fit ​​body 241. The snap-fit ​​body 241 is disposed at the bottom end of the connector 110 and extends axially along the connector 110. The slot 242 is formed on the connecting cylinder 222 and is axially arranged along the connecting cylinder 222. The snap-fit ​​body 241 is movably inserted into the slot 242.

[0042] The engagement of the snap-fit ​​body 241 and the slot 242 is physically locked to ensure that the connector 110 and the connecting cylinder 222 will not slip or separate, thus enhancing the stability of the railing. Especially during operation, under the vibration of the vehicle body 300 or the action of external forces, this snap-fit ​​structure effectively prevents the connection from loosening or separating, ensuring the safety of the operators.

[0043] The snap-fit ​​body 241 is movably inserted into the snap-fit ​​slot 242. No complicated tools or operations are required. Simply align the snap-fit ​​body 241 with the snap-fit ​​slot 242 and insert it easily to fix the railing. This improves the installation speed and reduces the difficulty of manual operation.

[0044] The movable insertion of the snap-fit ​​unit 240 can position the connector 110 so that each connector 110 is inserted into the corresponding connector 222 at the same angle. This ensures that the railing body and different connectors 222 cooperate with each other and avoids incorrect bending of different connectors 110, which would interfere with the insertion and removal of the connectors 110.

[0045] It should be noted that there are usually multiple snap-fit ​​units 240. Multiple snap-fit ​​units 240 are arranged at equal intervals around the connector 110. The snap-fit ​​units 240 can strengthen the connection between the connecting cylinder 222 and the connector 110, thereby enhancing the stability of the railing.

[0046] For further implementation details, please refer to [link / reference]. Figure 4 and Figure 5 The axial opening of the slot 242 allows the connecting cylinder 222 to withstand external forces along the longitudinal direction, thereby improving the bonding strength between the connector 110 and the connecting cylinder 222. The slot 242 dividing the connecting cylinder 222 can achieve a more uniform force distribution and avoid deformation or loosening caused by excessive local force.

[0047] The connecting sleeve 230, through compression, allows the connecting cylinder 222 to fit more tightly against the connector 110. This compression effect makes the fit between the connecting parts tighter, effectively preventing loosening or instability. The increased contact area between the connector 110 and the connecting cylinder 222 enhances the strength and tensile strength of the connection.

[0048] By segmenting the connecting cylinder 222, a more uniform force distribution is achieved, preventing damage caused by excessive force on a single connection point. The presence of the slot 242 allows the connecting cylinder 222 to effectively disperse the force transmission when under stress, enhancing the impact resistance of the entire connecting component.

[0049] During use, the connecting sleeve 230 presses inward against the connecting cylinder 222, ensuring greater friction and a tighter contact between the connected components. This tightening effectively reduces wear between components and improves durability over long-term use. Even under vibration or external impact, the connection remains stable. When necessary, the railing can be quickly removed from the vehicle body 300, facilitating the movement of machinery and personnel up and down the vehicle.

[0050] In some embodiments, please refer to Figure 5 and Figure 6 The connecting assembly 200 also includes a locking unit 250, which includes a movable pin 251 that is sequentially inserted into the connecting cylinder 222 and the connector 110.

[0051] The locking unit 250 effectively secures the connector 110 to the connecting cylinder 222, preventing loosening or detachment during operation. The locking function of the movable pin 251 ensures that the connector will not loosen due to accidental operation or vibration during use, protecting the safety of operators. The locking unit 250 provides additional protection, especially when used in dynamic environments.

[0052] The movable pin 251 allows the connecting parts to be quickly locked or unlocked via a simple pin operation. During installation, the user simply passes the pin through the connecting sleeve 222 and the connector 110 to easily secure it. During disassembly, the locking can also be quickly released by pulling out the pin, avoiding complicated tool operations.

[0053] Compared to traditional bolt and nut connections, the design of the movable pin 251 greatly simplifies the operation process, requiring no additional tools or time. Operators can complete installation and disassembly more quickly, improving work efficiency.

[0054] In a specific embodiment, please refer to Figure 5 and Figure 6 The locking unit 250 also includes a first insertion hole 252 and a second insertion hole 253. The first insertion hole 252 is formed on the connector 110 and is positioned opposite the locking body 241. The second insertion hole 253 is formed on the connecting cylinder 222 and is positioned opposite the slot 242. The first insertion hole 252 and the second insertion hole 253 are coaxially arranged. When the locking body 241 engages with the slot 242, the movable pin 251 is inserted into these two insertion holes respectively.

[0055] The first insertion hole 252 and the second insertion hole 253 are coaxially arranged, ensuring precise alignment when the movable pin 251 is inserted, and avoiding loose or unstable connections caused by asymmetrical pin positions. The coaxial arrangement ensures that the pin passes accurately through both holes during insertion, avoiding the risk of loose connections or improper installation due to misalignment.

[0056] The first insertion hole 252 and the second insertion hole 253 are provided so that the movable pin 251 can be inserted into these two holes to effectively lock the mating part of the snap-fit ​​body 241 and the slot 242, thereby enhancing the firmness of the connection and the ability to prevent loosening, ensuring that the connection component 200 remains fixed during operation and is not easily loosened due to external vibration or frequent operation.

[0057] The movable pin 251, inserted into two precisely mating mortise holes, provides a highly reliable mechanical locking function, making the connection of the entire railing system more secure and preventing connection failure caused by any external force or improper operation.

[0058] In some embodiments, please refer to Figure 8 The outer wall of the connecting sleeve 230 is provided with anti-slip strips 232. Multiple anti-slip strips 232 are equidistantly arranged around the axial direction of the connecting sleeve 230. The anti-slip strips 232 increase the coefficient of friction between the outer wall of the connecting sleeve 230 and the operator's hand or tools, allowing the operator to grip the connecting sleeve 230 more firmly during manual operation, installation, or disassembly. This effectively prevents errors caused by slipping hands in wet or oily environments, increasing safety during operation.

[0059] Workflow:

[0060] First, install the connector 220 at the predetermined position on the vehicle body 300, and connect the connector 220 and the interface of the vehicle body 300 with bolts to ensure that the connector 220 is firmly fixed on the vehicle body 300 and prevent it from loosening.

[0061] Then, insert the connector 110 into the connector 220 so that the snap-fit ​​body 241 can be smoothly inserted into the slot 242, and fix the railing by sliding or snapping to ensure that the connector 110 is inserted into the connector 220 and that its mating position is accurate.

[0062] Next, slip the connecting sleeve 230 onto the connector 110, ensuring a proper fit between the threaded portions of the connecting sleeve 230 and the connector 110. Tighten the connecting sleeve 230 using a tool to increase the friction between the connector 110 and the connecting sleeve 230, ensuring a secure connection of the railing.

[0063] Then, insert the movable pin 251 into the first insertion hole 252 and the second insertion hole 253 to complete the locking. At this time, the connector 110 and the connector 220 are now connected and fixed by the pin.

[0064] Finally, by reversing the above steps, the railing can be removed from the vehicle body 300, facilitating the movement of engineering equipment and personnel up and down.

[0065] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the present utility model.
