[0049] To solve the above technical problems, as shown in Figures 2-4 The present embodiment provides a fixing structure 3 of two components for fixing the support 2 and the support beam 1 in the above-mentioned escalator transportation system. The two components are a first component and a second component. In the present embodiment, the first component is the support beam 1, and the second component is the support 2.

[0050] In some embodiments, the opposite sides of the first component and the second component are respectively provided with a first plug-in part 101 and a second plug-in part 201. The fixing structure 3 comprises a first rotating part 301 and a second rotating part 302, the first rotating part 301 is rotatably connected with the first plug-in part 101, and the second rotating part 302 is rotatably connected with the second plug-in part 201.

[0051] Further, the first plug-in part 101 and the second plug-in part 201 are plug-in matched to form a first splicing joint 202, the first rotating part 301 and the second rotating part 302 are abutted to form a second splicing joint 303, and the first rotating part 301 can rotate together with the second rotating part 302, so that the first component and the second component have a locked state and an unlocked state; when the second splicing joint 303 is arranged at an angle with the first splicing joint 202, the first component and the second component are in the locked state, and when the second splicing joint 303 coincides with the first splicing joint 202, the first component and the second component are in the unlocked state. The quick fixing and dismounting between the two components are realized, the installation and dismounting steps are simplified, the operation is simple, and the work efficiency is improved.

[0052] In some embodiments, the first inserting part 101 comprises a first inserting groove 1011 and a first protruding part 1012, the first rotating part 301 is rotatably arranged on the first protruding part 1012, the second inserting part 201 comprises a second inserting groove 2011 and a second protruding part 2012, the second rotating part 302 is rotatably arranged on the second protruding part 2012, the second protruding part 2012 is insertedly matched with the first inserting groove 1011, the second inserting groove 2011 is insertedly matched with the first protruding part 1012, and a first splicing seam 202 is formed between the first protruding part 1012 and the second protruding part 2012. In this embodiment, the first inserting part 101 and the second inserting part 201 are insertedly matched to realize the splicing guidance and positioning of the first part and the second part, ensure the splicing precision, and improve the installation efficiency of the parts. In this embodiment, the first rotating part 301 and the second rotating part 302 are both semicircular rotating blocks.

[0053] Specifically, the first inserting groove 1011 and the first protruding part 1012 are arranged on the first part, and both are arranged on the side of the first part opposite to the second part. The second inserting groove 2011 and the second protruding part 2012 are arranged on the second part, and both are arranged on the side of the second part opposite to the first part, the first rotating part 301 is rotatably arranged on the first protruding part 1012, and the second rotating part 302 is rotatably arranged on the second protruding part 2012. When the first part and the second part are spliced, the first protruding part 1012 is inserted into the second inserting groove 2011, the second protruding part 2012 is inserted into the first inserting groove 1011, and the first splicing seam 202 is formed at the splicing position of the first protruding part 1012 and the second protruding part 2012.

[0054] Further, the first protruding part 1012 is provided with a first installation groove 106, the first rotating part 301 is arranged in the first installation groove 106, the second protruding part 2012 is provided with a second installation groove 208, and the second rotating part 302 is arranged in the second installation groove 208. The displacement of the first rotating part 301 and the second rotating part 302 in the radial direction is limited, so that the first rotating part 301 and the second rotating part 302 cannot be dislocated when the first part and the second part are installed, and the second splicing seam 303 cannot be formed.

[0055] Specifically, the first installation groove 106 is arranged at the top of the first protruding part 1012, and the first rotating part 301 can rotate in the first installation groove 106. The second installation groove 208 is arranged at the top of the second protruding part 2012, and the second rotating part 302 can rotate in the second installation groove 208. After the first protruding part 1012 and the second protruding part 2012 are spliced, the first installation groove 106 and the second installation groove 208 are spliced to form a circular accommodating groove, and the first rotating part 301 and the second rotating part 302 can jointly rotate in the circular accommodating groove after being spliced.

[0056] Preferably, the first rotating member 301 and the second rotating member 302, as the core components of the fixing structure 3 of the two components provided in the embodiment, can be made of hard metal or high-performance composite material, so that the first rotating member 301 and the second rotating member 302 have higher hardness, and the overall rigidity and service life of the fixing structure 3 are improved.

[0057] In some embodiments, the first rotating member 301 is provided with a pushing member 304, the first insertion part 101 is provided with a first recess 103, the first recess 103 is provided with a first elastic assembly 102, one end of the first elastic assembly 102 is connected with the groove wall of the first recess 103, and the other end is connected with the pushing member 304. The first rotating member 301 and the second rotating member 302 are butted, the pushing member 304 can drive the first rotating member 301 and the second rotating member 302 to jointly rotate to the unlocked state, and the elastic restoring force of the first elastic assembly 102 can drive the first rotating member 301 and the second rotating member 302 to jointly rotate to the locked state. The driving force is transmitted by the elastic restoring force of the first elastic assembly 102, which ensures the synchronization of the rotating process of the first rotating member 301 and the second rotating member 302 and the reliability of the driving force. At the same time, the first elastic assembly 102 can rely on its own continuous elastic force to apply a force to the pushing member 304 towards the groove wall of the first recess 103, so that the side wall of the pushing member 304 and the groove wall of the first recess 103 always remain in abutting state, avoiding the coincidence of the two splicing seams due to vibration or external interference.

[0058] Specifically, the pushing member 304 is rotatably arranged in the first recess 103 of the first component, one end of the pushing member 304 is fixedly connected with the peripheral wall of the first rotating member 301, one end of the first elastic assembly 102 is fixedly connected with the groove wall of the first recess 103, and the other end abuts against the pushing member 304. The first elastic assembly 102 can drive the pushing member 304 to rotate in the first recess 103 by the elastic force, and the pushing member 304 synchronously drives the first rotating member 301 and the second rotating member 302 to rotate to the first splicing seam 202 and the second splicing seam 303 coincide, at this time, the first component and the second component are in the unlocked state; the elastic restoring force of the first elastic assembly 102 drives the first rotating member 301 and the second rotating member 302 to rotate to the first splicing seam 202 and the second splicing seam 303 are arranged at an angle, at this time, the first component and the second component are in the fixed state.

[0059] In some embodiments, the fixed connection mode of the first elastic assembly 102 and the groove wall of the first recess 103 can be selected from welding or screwing and other connection modes, so as to improve the structural stability between the first elastic assembly 102 and the first recess 103.

[0060] In some embodiments, the second rotating member 302 is provided with a knob 305 on the circumferential side, and the second connecting part 201 is provided with a through slot 203 penetrating the outer wall of the second part, and the knob 305 extends out of the second part through the through slot 203. By operating the knob 305, the second rotating member 302 is driven to rotate, and since the second rotating member 302 abuts against the first rotating member 301, the second rotating member 302 can push the first rotating member 301 to rotate, so as to make the first joint 202 coincide with the second joint 303, thereby realizing the unlocking of the fixed structure 3 and facilitating the disassembly of the first part and the second part by the operator.

[0061] Specifically, the knob 305 is rotatably arranged in the through slot 203, one end of the knob 305 is fixedly connected to the side wall of the second rotating member 302, and the other end of the knob 305 extends out of the second part through the through slot 203. The operator can rotate the knob 305 by applying an external force to the extended part of the knob 305.

[0062] Preferably, the pushing member 304 is a pushing rod, and the knob 305 is a knob rod. The pushing member 304 and the knob 305 can be made of hard metal or high-performance composite material, so as to avoid deformation of the pushing member 304 and the knob 305 and improve the overall rigidity of the fixed structure 3.

[0063] Preferably, the pushing member 304 and the circumferential side wall of the first rotating member 301 need to be stably axially fixed, and the knob 305 and the circumferential side wall of the second rotating member 302 need to be stably axially fixed, so as to avoid relative displacement of the pushing member 304 and the first rotating member 301 and relative displacement of the knob 305 and the second rotating member 302 when the first rotating member 301 and the second rotating member 302 rotate. The fixing modes of the pushing member 304 and the first rotating member 301 and the fixing modes of the knob 305 and the second rotating member 302 can be selected according to actual working conditions, and specifically include but are not limited to clamping by buckling and slot cooperation. In this embodiment, epoxy resin glue is used for bonding, so as to improve the stability of the fixing between the pushing member 304 and the first rotating member 301 and the fixing between the knob 305 and the second rotating member 302. In order to facilitate the maintenance and replacement of the fixed structure 3 in the later stage, the pushing member 304 and the first rotating member 301 and the knob 305 and the second rotating member 302 can also be clamped and fixed by buckling and slot cooperation, which is convenient for assembly and disassembly, and can avoid falling off of the pushing member 304 and the first rotating member 301 and falling off of the knob 305 and the second rotating member 302.

[0064] Preferably, in addition to the above driving modes of the pushing member 304 driving the first rotating member 301 and the knob 305 driving the second rotating member 302, in the low-frequency operation scene, a manual direct driving implementation mode can also be directly used to drive the rotation of the first rotating member 301 and the second rotating member 302.

[0065] Further, the second insertion part 201 is also provided with a second groove 205, and the second elastic assembly 204 is arranged in the second groove 205. The second elastic assembly 204 is connected with the poking member 305, and the through groove 203 is communicated with the second groove 205. The second elastic assembly 204 can exert a force on the poking member 305 towards the groove wall of the through groove 203 by relying on the continuous elastic force of itself, so that the side wall of the poking member 305 and the groove wall of the through groove 203 always maintain the abutting state. Under the combined action of the abutting relationship of the first rotating member 301 and the abutting relationship, the relative rotation of the second rotating member 302 and the first rotating member 301 can be simultaneously limited, the state that the first splicing joint 202 and the second splicing joint 303 form an angle is maintained, and the fixing effectiveness of the first component and the second component in long-term use is further ensured.

[0066] Specifically, one end of the second elastic assembly 204 is fixedly connected with the groove wall of the second groove 205, the other end abuts against the poking member 305, and the second rotating member 302 can rotate in the through groove 203. The one end of the second elastic assembly 204 fixedly connected with the groove wall of the second groove 205 is opposite to the one end of the first elastic assembly 102 fixedly connected with the groove wall of the first groove 103. This reverse layout makes the driving force of the first elastic assembly 102 acting on the pushing member 304 and the driving force of the second elastic assembly 204 acting on the poking member 305 form equal size and opposite direction moments on the first rotating member 301 and the second rotating member 302, thereby forming a stable moment balance state, effectively limiting the rotation of the first rotating member 301 and the second rotating member 302 caused by external vibration or impact, avoiding the risk of the first splicing joint 202 and the second splicing joint 303 coinciding, and improving the overall stability of the fixing structure 3. In some embodiments, the fixed connection manner of the second elastic assembly 204 and the groove wall of the second groove 205 can be welding or the like, so as to improve the structural stability between the second elastic assembly 204 and the second groove 205.

[0067] In some embodiments, the first elastic assembly 102 includes a first telescopic member 1021 and a first elastic member 1022, the first elastic member 1022 is sleeved on the outer periphery of the first telescopic member 1021, the first telescopic member 1021 is connected with one side wall of the first groove 103 at the first end of the first elastic assembly 102, and the second end abuts against the pushing member 304; the second elastic assembly 204 includes a second telescopic member 2041 and a second elastic member 2042, the second elastic member 2042 is sleeved on the outer periphery of the second telescopic member 2041, the second telescopic member 2041 is connected with one side wall of the second limiting groove at the first end of the second elastic assembly 204, and the second end is connected with the poking member 305.

[0068] In some embodiments, the first telescopic member 1021 and the second telescopic member 2041 are both telescopic rods, and the first elastic member 1022 and the second elastic member 2042 are both springs. The two springs are respectively sleeved on the outer periphery of the two telescopic rods. Of course, the first elastic assembly 102 and the second elastic assembly 204 can also adopt other elastic structures, such as torsion springs. A fixed rotating column is arranged between the first groove 103 and the pushing member 304 and between the second groove 205 and the pushing member 305, respectively. Two torsion springs are sleeved on the outer periphery of the two fixed rotating columns. A clamping groove is arranged between the two side walls opposite to each other of the first groove 103 and the pushing member 304, and a clamping groove is arranged between the two side walls opposite to each other of the second groove 205 and the pushing member 305, for fixing the two torsion arms of the torsion springs. When the first component is mounted on the second component, the first rotating member 301 and the second rotating member 302 are synchronously rotated to the first splicing joint 202 and the second splicing joint 303 coincide, the torsion arms of the two torsion springs are deflected, the spring is torsionally deformed, and the elastic potential energy is stored. After the first component and the second component are mounted, the elastic restoring force of the spring drives the first rotating member 301 and the second rotating member 302 to synchronously rotate to the first splicing joint 202 and the second splicing joint 303 are arranged at an angle, and at the same time, the state of the first splicing joint 202 and the second splicing joint 303 being arranged at an angle is maintained through the elastic force of the spring, thereby improving the stability of the fixing structure 3.

[0069] In some embodiments, the first rotating member 301 is provided with a first guide groove 104, the first plug-in part 101 is provided with a first guide rod 105, the first guide rod 105 cooperates with the first guide groove 104; the second rotating member 302 is provided with a second guide groove 206, the second plug-in part 201 is provided with a second guide rod 207, the second guide rod 207 cooperates with the second guide groove 206, the first rotating member 301 rotates around the first guide rod 105 along the first guide groove 104, the second rotating member 302 rotates around the second guide rod 207 along the second guide groove 206, thereby avoiding the relative displacement of the first rotating member 301 and the second rotating member 302 when rotating, and improving the structural stability of the fixing structure 3. In this embodiment, the first guide groove 104 and the second guide groove 206 are both arc-shaped grooves, and the first guide rod 105 and the second guide rod 207 are both pins. In order to make the relative rotation of the first rotating member 301 and the second rotating member 302 more smooth, the first guide rod 105 and the second guide rod 207 in this embodiment are both provided with two.

Two first guide rods 105 in the first guide slot 104 are arranged at intervals along the first guide slot 104, and two second guide rods 207 in the second guide slot 206 are arranged at intervals along the second guide slot 206, which provide fulcrums for the rotation of the first rotating member 301 and the second rotating member 302, and improve the fluency of the synchronous rotation of the first rotating member 301 and the second rotating member 302.

[0071] In some embodiments, the opposite side walls of the through slot 203 are respectively the first limiting surface 2031 and the second limiting surface 2032. When the actuator 305 is rotated to abut against the first limiting surface 2031, the first splicing seam 202 is coincident with the second splicing seam 303; when the actuator 305 is rotated to abut against the second limiting surface 2032, the first splicing seam 202 is arranged at an angle with the second splicing seam 303. The fixing and dismounting between the first component and the second component can be completed only by rotating the actuator 305, which is simple in operation and improves the efficiency of fixing and dismounting between the two components.

[0072] The working principle of the above embodiments is as follows: When the operator needs to fix the first component and the second component, first, the first rotating member 301 is put into the first mounting slot 106 of the first component, and at the same time, the first guide rod 105 on the first component is inserted into the first guide slot 104 of the first rotating member 301; the second rotating member 302 is put into the second mounting slot 208 of the second component, and at the same time, the second guide rod 207 on the second component is inserted into the second guide slot 206 of the second rotating member 302; the first protruding part 1012 of the first component is inserted into the second insertion slot 2011 of the second component, and the second protruding part 2012 of the second component is inserted into the first insertion slot 1011 of the first component; under the elastic driving of the first elastic assembly 102 and the second elastic assembly 204, the first splicing seam 202 and the second splicing seam 303 are arranged at an angle, which ensures that the actuator 305 abuts against the first limiting surface 2031 and improves the stability of the fixing between the two components, and at this time, the two components are fixed. The operator actuates the actuator 305 to make the actuator 305 abut against the second limiting surface 2032, and the actuator 305 drives the second rotating member 302 to rotate, and the second rotating member 302 and the first rotating member 301 rotate together to make the first splicing seam 202 and the second splicing seam 303 coincide, at which time the first component and the second component are dismounted, and the operator can dismount the second component from the first component.

Various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the scope of the present application. It is not necessary or possible to enumerate all the embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
