Description

Technical Field

[0001] This utility model relates to connection structures, and in particular to a hinged assembly and a hookah device. Background Technology

[0002] The existing hookah device has a hinge structure, similar to a hinge mechanism, including a first connector and a second connector. The first connector is connected to the first housing of the hookah device, and the second connector is connected to the second housing of the hookah device. The first connector and the second connector can be rotated relative to each other to open the hookah device and add heatable material inside.

[0003] However, the existing hookah device has a hinged structure with a 360° relative rotation angle between the first and second connectors and lacks a stop function. This causes the first and second shells to rotate irregularly when adding heatable material into the hookah device, resulting in the second shell hitting the adding device and causing the adding to fail. This is not only inconvenient to operate, but also causes the heatable material to spill and be wasted, which greatly troubles consumers. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a hinge assembly and a hookah device with a simple structure and a stop structure.

[0005] This utility model discloses a hinge assembly, which includes a first connector and a second connector disposed on a connecting shaft. The first connector and the second connector are movable towards or away from each other in the vertical direction along the connecting shaft, and one of the first connector and the second connector is rotatable relative to the other about the axis of the connecting shaft. The surface of the first connector facing the second connector is respectively provided with a first protrusion and a first groove, and the surface of the second connector facing the first connector is respectively provided with a second groove and a second protrusion corresponding to the first protrusion and the first groove.

[0006] When the first connector and the second connector move toward each other, the first protrusion can extend into the second groove, and at the same time, the second protrusion can extend into the first groove; when the first connector and the second connector move in opposite directions along the connecting shaft and rotate around the connecting shaft, the first protrusion can abut against the second protrusion.

[0007] Furthermore, the length of the first protrusion extending out of the first connector is equal to the depth of the second groove, and the depth of the first groove is equal to the length of the second protrusion extending out of the second connector.

[0008] Furthermore, when the first connector and the second connector need to rotate around the connecting shaft, the travel distance of the first connector and the second connector moving in opposite directions is greater than or equal to the maximum value of the length of the first protrusion and the length of the second protrusion, and less than the sum of the lengths of the first protrusion and the second protrusion.

[0009] Furthermore, at least one end of the connecting shaft is provided with a limiting member to limit the maximum stroke of the back-to-back movement of the first connecting member and the second connecting member.

[0010] Furthermore, the connecting shaft is recessed with a limiting groove corresponding to the limiting member, and the limiting member is engaged in the limiting groove.

[0011] Furthermore, the first connector has a first movable hole in its middle part, the second connector has a second movable hole in its middle part, and the connecting shaft passes through the first movable hole and the second movable hole.

[0012] Furthermore, the lower end of the connecting shaft is fixedly installed in the first movable hole, the connecting shaft is slidably disposed in the second movable hole and the second connecting member can be slidably disposed up and down along the connecting shaft, and the limiting member is disposed at the upper end of the connecting shaft.

[0013] Furthermore, the side walls of the first protrusion and the second protrusion are both arranged radially with the axis of the connecting shaft as the center; the side walls of the first groove and the second groove are also arranged radially with the axis of the connecting shaft as the center.

[0014] Furthermore, the first protrusion is spaced apart from the first groove; the second protrusion is spaced apart from the second groove.

[0015] This utility model also discloses a hookah device, including a first housing and a second housing, and the aforementioned hinge assembly. The first connector is connected to the first housing, and the second connector is connected to the second housing. The first connector has a protruding first mounting block, and the first connector is fixedly mounted on the first housing through the first mounting block. The second connector has a protruding second mounting block, and the second connector is fixedly mounted on the second housing through the second mounting block.

[0016] The hinge assembly and hookah device provided by this utility model feature a first protrusion on the first connecting member and a second protrusion on the second connecting member. When the second connecting member rotates relative to the first connecting member around the connecting shaft, the first and second protrusions abut against each other to achieve a stop. This design not only simplifies the structure but also effectively prevents the second connecting member from rotating arbitrarily relative to the first connecting member, greatly facilitating consumers. Furthermore, the second connecting member has a second groove that mates with the first protrusion, and the first connecting member has a first groove that mates with the second protrusion. When the second connecting member abuts against the first connecting member, the insertion of the first protrusion into the second groove and the second protrusion into the first groove not only achieves relative locking between the second and first connecting members but also reduces the volume of the hinge assembly when closed, making it highly popular with consumers.

[0027] Please see Figures 1-6 This utility model discloses a hinge assembly 300 applied to a hookah device. The hinge assembly 300 includes a first connector 301 and a second connector 302 disposed on a connecting shaft 303. The first connector 301 and the second connector 302 can move towards or away from each other in the vertical direction along the connecting shaft 303, and one of the first connector 301 and the second connector 302 can rotate relative to the other about the axis of the connecting shaft 303. The surface of the first connector 301 facing the second connector 302 is respectively provided with a first protrusion 3013 and a first groove 3014. The second connector 302 faces the first connector 301. One side of the hinge assembly 300 is provided with a second groove 3024 and a second protrusion 3023 corresponding to the first protrusion 3013 and the first groove 3014, respectively. When the first connector 301 and the second connector 302 move toward each other, the first protrusion 3013 can extend into the second groove 3024, and at the same time, the second protrusion 3023 can extend into the first groove 3014. Furthermore, when the first connector 301 and the second connector 302 move a certain distance away from each other along the connecting shaft 303 and rotate around the axis of the connecting shaft 303, the first protrusion 3013 can abut against the second protrusion 3023.

[0028] Please see Figures 2-5The length of the first protrusion 3013 extending out of the first connector 301 is equal to the depth of the second groove 3024, and the depth of the first groove 3014 is equal to the length of the second protrusion 3023 extending out of the second connector 302. More specifically, the vertical projection of the first protrusion 3013 coincides with the second groove 3024, and the vertical projection of the second protrusion 3023 coincides with the first groove 3014, to ensure that when the second connector 302 and the first connector 301 move toward each other to fit together, the first protrusion 3013 is completely filled in the second groove 3024, and at the same time, the second protrusion 3023 is completely filled in the first groove 3014.

[0029] Please see Figure 6 To enable the first connector 301 and the second connector 302 to stop when they rotate relative to each other, when the first connector 301 and the second connector 302 need to rotate around the connecting shaft 303, the stroke of the first connector 301 and the second connector 302 moving in opposite directions must be greater than or equal to the maximum value of the length of the first protrusion 3013 and the length of the second protrusion, and less than the sum of the lengths of the first protrusion and the second protrusion.

[0030] Please see Figure 3 and Figure 6 Furthermore, at least one end of the connecting shaft 303 is provided with a limiting member 304 to limit the maximum stroke of the back-to-back movement of the first connecting member 301 and the second connecting member 302. More specifically, the connecting shaft 303 is recessed with a limiting groove 3031 corresponding to the limiting member 304, and the limiting member 304 is engaged within the limiting groove 3031.

[0031] In one embodiment, both ends of the connecting shaft 303 are provided with limiting members 304, and the limiting members 304 are engaged in the limiting grooves 3031. The first connecting member 301 has a first movable hole 3011 in its middle, and the second connecting member 302 has a second movable hole 3021 in its middle. The connecting shaft 303 passes through the first movable hole 3011 and the second movable hole 3021. At this time, both the first connecting member 301 and the second connecting member 302 can rotate around the connecting shaft 303, and the limiting members 304 located at both ends of the connecting shaft 303 restrict the stroke of the first connecting member 301 and the second connecting member 302 in opposite directions.

[0032] Please continue reading. Figure 6The limiting member 304 is disposed at the upper end of the connecting shaft 303 and engaged in the limiting groove 3031. The lower end of the connecting shaft 303 is fixedly installed in the first movable hole 3011. The connecting shaft 303 is slidably disposed in the second movable hole 3021, and the second connecting member 302 can slide up and down along the connecting shaft 303. The first connecting member 301 is fixed to the lower end of the connecting shaft 303, and the limiting member 304 is disposed at the upper end of the connecting shaft to limit the relative travel of the first connecting member 301 and the second connecting member 302, ensuring that the first connecting member 301 and the second connecting member 302 can stop when they rotate relative to each other, thus preventing 360° rotation.

[0033] Please see Figure 4 and Figure 5 The two side walls of the first protrusion 3013 and the second protrusion 3023 are both arranged radially with the axis of the connecting shaft 303 as the center; the two side walls of the first groove 3014 and the second groove 3024 are also arranged radially with the axis of the connecting shaft 303 as the center, so as to achieve face-to-face contact when the first protrusion 3013 and the second protrusion 3023 abut against each other.

[0034] In this embodiment, the first protrusion 3013 and the first groove 3014 are spaced apart; the second protrusion 3023 and the second groove 3024 are spaced apart. In other embodiments, the first protrusion 3013 and the first groove 3014 may also be connected; the second protrusion 3023 and the second groove 3024 may also be connected. Furthermore, the positions of the first protrusion 3013 and the second protrusion 3023 are set according to the rotation angle requirements of the first connector 301 and the second connector 302.

[0035] Please see Figure 1 The present invention also discloses a hookah device, including a first housing 100 and a second housing 200, and the aforementioned hinge assembly 300, wherein the first connector 301 is connected to the first housing 100, and the second connector 302 is connected to the second housing 200.

[0036] Please see Figures 1-6 The first connector 301 has a first mounting block 3012 protruding from its side wall. The first connector 301 is fixedly mounted on the first housing 100 through the first mounting block 3012. The second connector 302 has a second mounting block 3022 protruding from its side wall. The second connector 302 is fixedly mounted on the second housing 200 through the second mounting block 3022.

[0037] When the hinge assembly 300 and the hookah device of this utility model are used...

[0038] First, the second housing 200 is pulled upward relative to the first housing 100. At the same time, the second connector 302 moves upward relative to the first connector 301 along the connecting shaft 303. When the second connector 302 abuts against the limiting member 304, the first protrusion 3013 disengages from the second groove 3024, and the second protrusion 3023 disengages from the first groove 3014.

[0039] Next, the second housing 200 is rotated clockwise around the axis of the connecting shaft 303, that is, the second connector 302 rotates around the axis of the connecting shaft 303. When the first protrusion 3013 abuts against the second protrusion 3023, the second housing 200 stops rotating, and a heatable material can be added into the first housing 100 so that the water pipe device can heat the heatable material to generate smoke for the consumer to inhale.

[0040] Finally, the second housing 200 is rotated counterclockwise around the axis of the connecting shaft 303, that is, the second connector 302 rotates around the axis of the connecting shaft 303. When the second housing 200 and the first housing 100 are completely coincident in the vertical projection direction, the first protrusion 3013 corresponds to the second groove 3024, and the second protrusion 3023 corresponds to the first groove 3014. Then, the second housing 200 is placed on the first housing 100, the first protrusion 3013 extends into the second groove 3024, and the second protrusion 3023 extends into the first groove 3014. The first housing 100 and the second housing 200 form a heating space for the heatable material to be heated in the heating space.

[0041] The hinge assembly and hookah device provided by this utility model have a first protrusion 3013 provided in the first connector 301 and a second protrusion 3023 provided in the second connector 302. When the second connector 302 rotates relative to the first connector 301 around the connecting shaft 303, the first protrusion 3013 and the second protrusion 3023 abut against each other to stop the rotation. This not only has a simple structure, but also effectively prevents the second connector 302 from rotating randomly relative to the first connector 301, which greatly facilitates consumers. In addition, the second connector 302 is provided with a second groove 3024 that cooperates with the first protrusion 3013, and the first connector 301 is provided with a first groove 3014 that cooperates with the second protrusion 3023. When the second connector 302 abuts against the first connector 301, the first protrusion 3013 is inserted into the second groove 3024, and the second protrusion 3023 is inserted into the first groove 3014. This not only achieves relative locking between the second connector 302 and the first connector 301, but also reduces the volume of the hinge assembly 300 when closed, which is very popular with consumers.

[0042] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
