[0001] The utility model belongs to the technical field of barbecue equipment, and particularly relates to a double-axis telescopic synchronous structure and a barbecue machine applying the same. Background Art

[0002] In the existing double-axis telescopic structure, two telescopic members are often rigidly connected to a connecting component. During use, if the pushing or pulling force applied to the connecting component is not in the same direction as the telescopic direction of the telescopic member, it will cause the two telescopic members to approach each other or turn outwards, generating a bending moment on the telescopic member. Since there is a certain gap between the multiple sections of the telescopic member for sliding, the bending moment generated thereon will cause an angular deviation of the central axis of the telescopic member, resulting in unsmooth telescoping, easy jamming or jamming, and affecting the use effect. Summary of the Utility Model

[0003] In view of this, the purpose of the present utility model is to provide a double-axis telescopic synchronous structure, which solves the problems of unsmooth telescoping, easy jamming or jamming, and affecting the use effect of the existing double-axis telescopic structure during use.

[0004] The purpose of the present utility model is also to provide a barbecue machine applying the above double-axis telescopic synchronous structure.

[0005] To achieve the above purpose, the first technical solution of the present utility model is realized as follows: A double-axis telescopic synchronous structure includes two relatively arranged telescopic shafts, a crossbeam assembly, and a connecting component. The crossbeam assembly is located between the two telescopic shafts, and both ends of the crossbeam assembly are respectively connected to the two telescopic shafts through the connecting component; during the process of pushing the crossbeam assembly to drive the two telescopic shafts to telescope, the connecting component ensures that the telescopic directions of the two telescopic shafts are the same, avoiding the phenomenon of jamming or jamming of the two telescopic shafts.

[0006] Further, the crossbeam assembly includes at least two crossbeams, and both ends of each crossbeam are respectively connected to the two telescopic shafts through the connecting component.

[0007] Further, U-shaped fixing clips are provided at both ends of the crossbeam, and the connecting component is inserted into the U-shaped fixing clips and the two are cooperatively connected.

[0008] Further, two crossbeams are provided, and both ends of the two telescopic shafts are respectively hinged to the U-shaped fixing clips at both ends of the crossbeam through the connecting component.

[0009] Further, two crossbeams are provided, and the ends of the two telescopic shafts on the same side are fixed to the U-shaped fixing clips at both ends of the crossbeam through the connecting component, and the ends on the other side are hinged to the U-shaped fixing clips at both ends of the crossbeam through the connecting component.

[0010] Further, the connecting component includes a sleeve, a rotating member and an ear plate arranged on the outer side wall of the sleeve. A fixing hole is provided on the ear plate. A through hole for penetrating the rotating member is formed at a position corresponding to the rotating member on the U-shaped fixing clip, and a connecting hole is formed at a position corresponding to the fixing hole on the U-shaped fixing clip.

[0011] Further, a positioning member is provided on the inner wall of the sleeve, and a positioning hole for cooperating with the positioning member is provided on the side wall of the telescopic shaft near the end; or a positioning hole is provided on the side wall of the sleeve, and a positioning member for cooperating with the positioning hole is provided on the outer side wall of the telescopic shaft near the end.

[0012] Further, the end of the sleeve away from the telescopic shaft is bent towards the axis of the sleeve to form an anti-drop retaining ring.

[0013] Further, a locking opening is axially formed on the sleeve wall, and two groups of ear plates are provided. The two groups of ear plates are respectively located on both sides of the locking opening.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the ends of the two telescopic shafts are connected to the ends of the crossbeam assembly through the connecting component. When the pushing and pulling force received on the crossbeam assembly is inconsistent with the telescopic direction of the two telescopic shafts, the connecting component can eliminate the bending moment generated by the unbalanced force at the end of the telescopic shaft, so that the two telescopic shafts only bear the pushing and pulling force along their own axial directions, avoiding the phenomenon of jamming or jamming when the telescopic shafts are telescopic, and greatly improving the smoothness of the double-shaft telescopic and the user experience effect.

[0024] Embodiment 1

[0025] As Figure 1 shown, a dual-axis telescopic synchronization structure provided in this embodiment includes two relatively arranged telescopic shafts 1, a crossbeam assembly 2, and a connection component 3. The crossbeam assembly 2 is located between the two telescopic shafts 1, and both ends of the crossbeam assembly 2 are respectively connected to the two telescopic shafts 1 through the connection component 3. During the process of pushing the crossbeam assembly 2 to drive the two telescopic shafts 1 to expand and contract, the connection component 3 ensures that the expansion and contraction directions of the two telescopic shafts 1 are the same, avoiding the phenomenon that the two telescopic shafts 1 are stuck or jammed.

[0026] Based on the above structure, the two-axis telescopic synchronization structure connects the ends of two telescopic shafts 1 to the crossbeam assembly 2 through the connection assembly 3. When the pushing or pulling force applied by the user on the crossbeam assembly 2 is not in the same direction as the telescopic direction of the two telescopic shafts 1, the connection assembly 3 can eliminate the bending moment generated by the unbalanced force at the end of the telescopic shaft 1, so that the two telescopic shafts 1 only bear the pushing and pulling force along their own axial directions, avoiding the phenomenon of jamming or jolting when the telescopic shafts 1 are telescoping, and greatly improving the smoothness of the telescoping of the two telescopic shafts 1 and the user experience effect.

[0027] In some embodiments of the present application, the crossbeam assembly 2 includes at least two crossbeams 21, and both ends of each crossbeam 21 are respectively connected to the two telescopic shafts 1 through the connection assembly 3; the number of connection assemblies 3 provided is twice the number of crossbeams 21.

[0028] As Figure 2 and Figure 4 shown, in some embodiments of the present application, U-shaped fixing clips 211 are provided at both ends of the crossbeam 21, and the connection assembly 3 is inserted into the U-shaped fixing clips 211 and the two are cooperatively connected.

[0029] In this embodiment, the connection assembly 3 is inserted into the U-shaped fixing clip 211 and the two are cooperatively connected to ensure the uniformity of force transmission between the crossbeam 21 and the connection assembly 3.

[0030] In some embodiments of the present application, there are two crossbeams 21, and both ends of the two telescopic shafts 1 are respectively hinged to the U-shaped fixing clips 211 at both ends of the crossbeam 21 through the connection assembly 3; in this embodiment, the rotational connection between both ends of the telescopic shaft 1 and the crossbeam 21 is indirectly realized through the connection assembly 3, which can eliminate the bending moment generated by the unbalanced force applied to the telescopic shaft 1 through the crossbeam 21 on the central axis of the telescopic shaft 1 and ensure the smoothness of telescoping.

[0031] As Figure 5 shown, in some embodiments of the present application, the connection assembly 3 includes a sleeve 31 and a rotating member 32 provided on the outer sidewall of the sleeve 31. The end of the telescopic shaft 1 extends into the sleeve 31, and a through hole 212 for penetrating the rotating member 32 is opened at a position on the U-shaped fixing clip 211 corresponding to the rotating member 32, so that the U-shaped fixing clip 211 is hinged to the rotating member 32.

[0032] When this embodiment is in use, the end of the telescopic shaft 1 is inserted into the sleeve 31 of the connecting component 3, so that the telescopic shaft 1 and the sleeve 31 have the same axis. The rotating member 32 on the outer side wall of the sleeve 31 is rotatably inserted into the corresponding through hole 212 on the U-shaped fixing clip 211. When the pushing or pulling force applied to the U-shaped fixing clip 211 is not consistent with the telescopic direction of the telescopic shaft 1, the U-shaped fixing clip 211 can rotate relative to the sleeve 31 to eliminate the bending moment transmitted from the cross beam 21 to the telescopic shaft 1, so that the telescopic shaft 1 only bears the pushing or pulling force along its own axis direction, ensuring the smooth telescoping of the telescopic shaft 1.

[0033] In some embodiments of the present application, the rotating member 32 is a rotating shaft extending radially along the sleeve 31, and the rotating shaft is rotatably connected in the through hole 212 on the U-shaped fixing clip 211.

[0034] In some embodiments of the present application, there are two cross beams 21. The ends on the same side of the two telescopic shafts 1 are fixed to the U-shaped fixing clips 211 at both ends of the cross beam 21 through the connecting component 3, and the ends on the other side are hinged to the U-shaped fixing clips 211 at both ends of the cross beam 21 through the connecting component 3.

[0035] In this embodiment, the unbalanced force applied to the telescopic shaft 1 through the cross beam 21 will cause the hinge joint between the connecting component 3 and the U-shaped fixing clip 211 to rotate, and then be eliminated, so as to ensure the smooth coaxial telescoping of the two telescopic shafts 1.

[0036] In some embodiments of the present application, the connecting component 3 includes a sleeve 31, a rotating member 32 and an ear plate 35 provided on the outer side wall of the sleeve 31. The ear plate 35 is provided with a fixing hole 36. A through hole 212 for penetrating the rotating member 32 is opened at a position corresponding to the rotating member 32 on the U-shaped fixing clip 211, and a connecting hole 213 is opened at a position corresponding to the fixing hole 36 on the U-shaped fixing clip 211.

[0037] When this embodiment is in use, the ends on the same side of the two telescopic shafts 1 are rotatably connected to the U-shaped fixing clips 211 at both ends of the cross beam 21 through the rotating member 32 in the connecting component 3, and the ends on the other side of the two telescopic shafts 1 are fixedly connected through structures such as bolts inserted into the fixing hole 36 and the connecting hole 213. When the telescopic shaft 1 is pushed through the cross beam 21, the applied unbalanced force will be eliminated through the rotation of the rotating member 32 and the U-shaped fixing clip 211, so as to ensure the smooth coaxial telescoping of the two telescopic shafts 1.

[0038] Such as Figure 3 、 Figure 5As shown, in some embodiments of the present application, a positioning member 33 is provided on the inner wall of the sleeve 31, and a positioning hole 11 that cooperates with the positioning member 33 is provided on the side wall of the telescopic shaft 1 near the end; or a positioning hole 11 is provided on the side wall of the sleeve 31, and a positioning member 33 that cooperates with the positioning hole 11 is provided on the outer side wall of the telescopic shaft 1 near the end.

[0039] In this embodiment, when in use, the end of the telescopic shaft 1 is inserted into the sleeve 31. After reaching the specified position, the positioning member 33 is snapped into the positioning hole 11 to limit the axial position and circumferential position of the telescopic shaft 1 in the sleeve 31, and the structure is simple, and the installation and disassembly are convenient to operate.

[0040] In some embodiments of the present application, the end of the sleeve 31 away from the telescopic shaft 1 is bent towards the axis of the sleeve 31 to form an anti - detachment retaining ring 34.

[0041] Specifically, the telescopic shaft 1 is composed of multiple small sections connected in series. In this embodiment, by providing the anti - detachment retaining ring 34 on the sleeve 31, when the telescopic shaft 1 expands and contracts, the ends of multiple small sections can be in contact with the anti - detachment retaining ring 34, avoiding detachment and ensuring the use effect.

[0042] In some embodiments of the present application, a locking opening is axially formed on the wall of the sleeve 31, and two groups of ear plates 35 are provided. The two groups of ear plates 35 are respectively located on both sides of the locking opening.

[0043] Specifically, the cross - section of the sleeve 31 is C - shaped, and the two groups of ear plates 35 are respectively located on both sides of the C - shaped notch. Each group of ear plates 35 includes at least one ear plate 35. In this embodiment, by setting bolts in the fixing holes 36 to connect the two ear plates 35, the C - shaped notch on the sleeve 31 is narrowed, prompting the sleeve 31 to clamp the telescopic shaft 1 inserted therein, ensuring the stability of the connection between the sleeve 31 and the telescopic shaft 1.

[0044] The working principle of the double - shaft telescopic synchronization structure provided by this embodiment is as follows:

[0045] When in use, the user pushes the cross - beam 21 inward from both ends of the telescopic shaft 1 or pulls the cross - beam 21 outward, and then drives the two telescopic shafts 1 to expand and contract synchronously through the connection assembly 3. During this process, if the pushing and pulling force applied to the cross - beam 21 is not consistent with the expansion and contraction direction of the telescopic shaft 1, the rotating member 32 in the connection assembly 3 will rotate relative to the U - shaped fixed clip 211 in the cross - beam 21 to eliminate the bending moment generated by this unbalanced force on the end of the telescopic shaft 1, so that the telescopic shaft 1 only bears the force along its own axis direction, avoiding the telescopic shaft 1 from being stuck or jammed, and ensuring the smoothness of the expansion and contraction of the double - shaft telescopic synchronization structure and the use experience.

[0047] A barbecue grill, comprising two heating mechanisms and the double-axis telescopic synchronization structure described in Embodiment 1, and the two heating mechanisms are respectively arranged at both ends of the two telescopic shafts 1 in the double-axis telescopic synchronization structure.

[0048] In this embodiment, the two heating mechanisms are respectively arranged at both ends of the telescopic shaft 1. By arranging a structure such as a grill between the two heating mechanisms to place food for barbecue, it can avoid the oil from dripping on the heat source during the baking of food, resulting in oil fumes, and can also avoid frequent cleaning of the heating mechanism.

[0049] In addition, through this double-axis telescopic synchronization structure, the distance between the two heating mechanisms can be adjusted, which is convenient for baking different amounts of food, meets the usage requirements of multiple people dining, and is also convenient for shrinking the size for storage, saving kitchen storage space.

[0050] In some embodiments of the present application, connection plates 214 are arranged at the ends of at least two cross beams 21, and the connection plates 214 are connected to the heating mechanism by bolts to increase the connection stability between the double-axis telescopic synchronization structure and the heating mechanism.
