Description

Technical Field

[0001] The present invention relates to an assembly structure, and in particular to an assembly structure provided with a groove, wherein the assembly structure can be disassembled or assembled only after a clamping piece is inserted into the groove. Background Art

[0002] The assembly structure of existing table lamps or floor lamps is designed to allow the inner joint component and the outer joint component to rotate relative to each other, so that the lighting device set in the assembly structure can change its lighting angle, adjust the brightness or be switched on and off. However, the assembly structure of the Chinese patent application CN201922245446.1 only provides two-stage rotation of the lamp, but cannot rotate steplessly and cyclically, and during the rotation process, the outer joint component and the inner joint component may sometimes loosen from each other. Summary of the invention

[0003] The object of the present invention is to provide an assembly structure in which an inner joint component and an outer joint component can achieve stepless and cyclic rotation, and the assembly structure can be disassembled or installed only by means of a clamping member to prevent the outer joint component and the inner joint component from loosening from each other during relative rotation.

[0004] The technical means adopted by the present invention are described as follows.

[0005] According to the purpose of the present invention, an assembly structure is provided, which includes an outer joint component and an inner joint component. The outer joint component includes a first shell, wherein a first accommodating space is formed inside the first shell, the first shell has a first outer surface and a first inner surface, the first outer surface and the first inner surface correspond to each other, and the first inner surface forms a first locking structure at the first accommodating space. The inner joint component includes a second shell and a core component, wherein the core component is composed of a core and a third shell, the second shell can extend into the first accommodating space, a second accommodating space is formed inside the second shell, the second shell has a second outer surface and a second inner surface, the second outer surface and the second inner surface correspond to each other, the second outer surface forms a second locking structure corresponding to the first locking structure, the core can extend into the second accommodating space, one side of the core is connected to one side of the third shell, the outer surface of the core is in contact with the second inner surface, and a groove is formed between the second shell and the third shell.

[0006] According to the above technical features, when the clamp is inserted into the groove, the two sides of the clamp are respectively clamped to the second shell and the third shell, and the second locking structure can be rotationally locked or rotationally unlocked with the first locking structure, so that the outer joint component and the inner joint component can be disassembled or assembled. When the clamp is not inserted into the groove, the second locking structure cannot be rotationally locked or rotationally unlocked with the first locking structure, but the core component can rotate relative to the second shell about the rotation axis.

[0007] According to the above technical features, when the clamping part is not inserted into the groove, the first maximum static friction force that needs to be overcome when the core component is rotated relative to the second shell about the rotation axis is smaller than the second maximum static friction force that needs to be overcome when the second locking structure is rotationally locked or rotationally unlocked with the first locking structure. Therefore, when the core component is rotated relative to the second shell about the rotation axis, the second locking structure cannot be rotationally locked or rotationally unlocked with the first locking structure.

[0008] According to the above technical features, when the clamping part is inserted into the groove, one side of the clamping part contacts the second shell and generates a third maximum static friction force that needs to be overcome when the core component is rotated relative to the second shell about the rotation axis, wherein the third maximum static friction force is greater than the second maximum static friction force, so that when the second locking structure and the first locking structure are rotationally locked or rotationally unlocked, the core component cannot rotate relative to the second shell about the rotation axis.

[0009] According to the above technical features, the first locking structure includes a plurality of first threads, and the second locking structure includes a plurality of second threads relative to the plurality of first threads, so that the first locking structure and the second locking structure can be rotatably engaged.

[0010] According to the above technical features, an electrical base or an electrical connector is provided on a side of the core away from the third shell.

[0011] According to the above technical features, the first shell also has an inner wall surface, which is arranged in the first accommodating space, connected to the first inner surface and perpendicular to the first inner surface, and the inner wall surface is provided with an electrical base or an electrical connector.

[0012] According to the above technical features, the core and the third shell are integrally formed to form a core assembly.

[0013] According to the above technical features, the core and the third shell are connected to each other by at least one fixing means to form a core assembly.

[0014] According to the above technical features, the internal joint assembly further includes a limiting ring, which is connected to the side of the second shell away from the groove and partially protrudes from the second inner surface, and a limiting hole is provided on the outer surface of the core away from the third shell, so that when the core extends into the second accommodating space, the part of the limiting ring protruding from the second inner surface will be received in the limiting hole to limit the core.

[0015] In summary, the embodiment of the present invention provides an assembly structure with a groove, wherein only when the groove is inserted into a clamping piece, the inner joint component and the outer joint component can be rotationally locked or rotationally unlocked, otherwise the inner joint component can only be rotated relative to the outer joint component, but cannot be rotationally locked or rotationally unlocked. Accordingly, the technical problem that the inner joint component and the outer joint component are easily loosened when the inner joint component is rotated to rotate the electrical device installed on the inner joint component can be reduced.

[0054] In order to solve the problem of loosening that may occur in the assembly structure of the prior art when the user wants to rotate the inner joint component to change the rotation process of the lighting device installed in the inner joint component, an embodiment of the present invention provides an assembly structure with a groove, wherein only when a clamping piece is inserted into the groove can the inner joint component and the outer joint component be rotationally locked or rotationally unlocked. Otherwise, the inner joint component can only rotate relative to the outer joint component but cannot be rotationally locked or rotationally unlocked.

[0055] Please refer to Figure 1 , Figure 11 is a three-dimensional schematic diagram of an electrical device using the assembly structure of the first embodiment of the present invention. In this embodiment, the electrical device is a table lamp or a floor lamp, but the present invention does not limit the application of the assembly structure 100 by the type of electrical device. The electrical device in this embodiment includes a plurality of external joint components 1, a plurality of internal joint components 2 and a base B. Each external joint component 1 can be connected to at least one or more internal joint components 2, and each internal joint component 2 can be connected to at least one or more external joint components 1. In addition, one of the upright external joint components 1 is connected to the base B. An electrical device LP, such as a lighting device, a heating device, a display device or other electrical device, can be installed in the internal joint component 2. In this embodiment, one of the external joint components 1 is L-shaped, but the present invention is not limited to this.

[0056] The assembly structure 100 may have a groove S (eg Figure 2 As shown), without the card member H (as shown Figure 5 and Figure 6 When the second housing 21 (as shown in FIG. Figure 4 ) and the outer joint assembly 1 cannot be rotationally locked or rotationally unlocked, but the core assembly 24 of the inner joint assembly 2 (as shown Figure 4 The inner joint assembly 2 (as shown) can be rotated relative to the outer joint assembly 1, so that the electrical device LP installed in the inner joint assembly 2 can be rotated together. In this way, the technical problem that the inner joint assembly 2 and the outer joint assembly 1 are easily loosened when the electrical device LP is rotated can be solved. In addition, the groove S can be deliberately designed to have the same thickness as a general credit card, coin or EasyCard, so that the user can use the belongings as the card member H when disassembling and installing the assembly structure 100.

[0057] Please refer to Figure 2 , Figure 3 and Figure 4 , Figure 2 is a structural disassembly diagram of the assembly structure of the first embodiment of the present invention, Figure 3 is a structural disassembly diagram of the inner joint assembly of the assembly structure of the first embodiment of the present invention, and Figure 4 1 is a cross-sectional view of the assembly structure of the first embodiment of the present invention. The external connector assembly 1 includes a first housing 11, wherein Figure 2 , Figure 3 and Figure 4 The assembly structure 100 is a reflection of Figure 1The first housing 11 has a first accommodating space S1 formed inside. The first housing 11 has a first outer surface 111 and a first inner surface 112. The first outer surface 111 and the first inner surface 112 correspond to each other, and the first inner surface 112 has a first locking structure 113 formed at the first accommodating space S1. The first inner surface 112 is an annular inner surface, but the first outer surface 111 may be a non-annular outer surface.

[0058] The inner joint assembly 2 includes a second shell 21 and a core assembly 24, wherein the core assembly 24 is composed of a core 22 and a third shell 23, and one side of the core 22 is connected to one side of the third shell 23. The core 22 can be integrally formed with the third shell 23 to form the core assembly 24, or the core 22 and the third shell 23 are connected to each other by at least one fixing means to form the core assembly 24, wherein the fixing means is, for example, a screw SC, but the present invention is not limited thereto, and other types of fixing means such as bonding, welding, riveting, clamping or nailing can be used.

[0059] The second shell 21 can extend into the first accommodation space S1, and a second accommodation space S2 is formed inside the second shell 21. The second shell 21 has a second outer surface 211 and a second inner surface 212, and the second outer surface 211 and the second inner surface 212 correspond to each other. The second inner surface 212 is an annular inner surface, but the second outer surface 211 is an annular outer surface. The second outer surface 211 is formed with a second locking structure 213 corresponding to the first locking structure 113. The first locking structure 113 includes a plurality of first threads, and the second locking structure 213 includes a plurality of second threads relative to the plurality of first threads, so that the first locking structure 113 and the second locking structure 213 can be rotatably engaged. The core 22 can extend into the second accommodation space S2, and the outer surface 221 of the core 22 contacts the second inner surface 212, and a groove S is formed between the second shell 21 and the third shell 23.

[0060] In addition, the inner joint assembly 2 may selectively further include a limiting ring CR. The limiting ring CR is connected to a side of the second shell 21 away from the groove S and partially protrudes from the second inner surface 212, and a limiting hole 222 is provided at the outer surface 221 of the core 22 away from the third shell 23, so that when the core 22 extends into the second accommodating space S2, the portion of the limiting ring CR protruding from the second inner surface 212 will be received in the limiting hole 222, thereby limiting the core 22.

[0061] When the clamping member H is not inserted into the groove S, the second locking structure 213 cannot be rotationally locked or rotationally unlocked with the first locking structure 113, but the core component 24 can rotate relative to the second housing 21 about the rotation axis X. In other words, at this time, the inner joint component 2 can rotate relative to the outer joint component 1, but the inner joint component 2 and the outer joint component 1 will not be loosened.

[0062] Furthermore, when the clamping member H is not inserted into the groove S, when the core component 24 is rotated relative to the second shell 21 about the rotation axis X, it is necessary to overcome the first maximum static friction force existing when the outer surface 221 of the core 22 contacts the second inner surface 212 of the second shell 21. The second locking structure 213 and the first locking structure 113 are in contact with each other, so there will be a second maximum static friction force. In terms of design, the first maximum static friction force is smaller than the second maximum static friction force through the selection of materials, surface roughness or other factors affecting the maximum static friction force. Therefore, when the user applies a rotation force greater than the first maximum static friction force, the core component 24 will be rotated relative to the second shell 21 about the rotation axis X in a stepless cycle. At this time, there is still dynamic friction when the outer surface 221 of the core 22 contacts the second inner surface 212 of the second shell 21. Therefore, as long as the rotation force does not instantly exceed the second maximum static friction force, the second locking structure 213 cannot be rotationally locked or rotationally unlocked with the first locking structure 113.

[0063] Please continue, refer to Figure 5 and Figure 6 , Figure 5 is a cross-sectional view of the assembly structure of the first embodiment of the present invention when being disassembled, and Figure 6 It is a cross-sectional view of the assembly structure of the first embodiment of the present invention when it is installed. When the assembly structure 100 is to be disassembled or installed, as long as the clamping member H is inserted into the groove S, the two sides H1 and H2 of the clamping member H will be clamped on the second shell 21 and the third shell 23 respectively, so that the second locking structure 213 can be rotationally locked or rotationally unlocked with the first locking structure 113, but the core component 24 cannot rotate relative to the second shell 21 about the rotation axis X, so that the outer joint component 1 and the inner joint component 2 can be disassembled or assembled.

[0064] Furthermore, when the clamping member H is inserted into the groove S, one side H of the clamping member H contacts the second shell 21, so there is a third maximum static friction force generated by one side H1 of the clamping member H and the second shell 21. At this time, if the core component 24 is to be able to rotate relative to the second shell 21 with the rotation axis X, a rotation force that is instantly greater than the third maximum static friction force is required. In terms of design, the third maximum static friction force is greater than the second maximum static friction force through the selection of materials, surface roughness or other factors that affect the maximum static friction force. Therefore, when the user applies a rotation force greater than the second maximum static friction force, the second locking structure 213 and the first locking structure 113 will be rotationally locked or rotationally unlocked. At this time, there is still dynamic friction between the second locking structure 213 and the first locking structure 113. Therefore, as long as the rotation force does not instantly exceed the third maximum static friction force, the core component 24 cannot rotate relative to the second shell 21 with the rotation axis X.

[0065] Please refer to Figure 7 and Figure 8 , Figure 7 is a cross-sectional view of an assembly structure of a second embodiment of the present invention, and Figure 8 It is a cross-sectional view of the assembly structure of the third embodiment of the present invention. Since the inner joint component 2 may have an electrical device LP installed therein, it is necessary to set an electrical base SL or an electrical connector PL in the inner joint component 2 or the outer joint component 1, wherein the electrical base SL or the electrical connector PL can be used for transmitting signals in addition to power supply. When the electrical device LP is an LED lighting device, the electrical base SL or the electrical connector PL can adopt the specifications of a T8 lamp tube. For example, the electrical base SL and the electrical connector PL can be a ring-shaped electrical socket and a ring-shaped plug, respectively, and the ring-shaped electrical socket and the ring-shaped plug can be the specifications of a single-pin electrical socket and a plug of a T8 lamp tube, but the present invention is not limited thereto, so the ring-shaped electrical socket and the ring-shaped plug can also rotate steplessly in a cycle with each other.

[0066] At Figure 7 In the figure, the side of the core 22 of the left assembly structure away from the third shell 23 is provided with an electrical connector PL, and the side of the core 22 of the right assembly structure away from the third shell 23 is provided with an electrical base SL, and the electrical connector PL is inserted into the electrical base SL to electrically connect the electrical devices in the left and right inner connector assemblies 2 in series. Figure 8 In the embodiment, the core 22 is provided with an electric base SL on one side away from the third shell 23, and the inner wall 114 of the outer connector assembly 1 is provided with an electric connector PL, wherein the inner wall 114 is arranged in the first accommodation space S1, and the inner wall 114 is connected to the first inner surface 112 and is perpendicular to the first inner surface 112. In addition, Figure 8 The third embodiment can also be modified so that the electric base SL and the electric connector PL are respectively arranged in the outer connector assembly 1 and the inner connector assembly 2.

[0067] Accordingly, compared to the prior art, the assembly structure of the present invention can reduce the technical problem that the inner joint component and the outer joint component are easily loosened when the inner joint component is rotated to rotate the electrical device installed on the inner joint component. On the other hand, through the assembly structure of the present invention, the inner joint component can be rotated steplessly and cyclically to rotate the electrical device installed on the inner joint component. Simply put, only when the groove is inserted into the clamping piece can the inner joint component and the outer joint component be allowed to be rotationally locked or rotationally unlocked, otherwise the inner joint component can only be rotated relative to the outer joint component, but cannot be rotationally locked or rotationally unlocked.
