Description

Technical Field

[0001] This utility model relates to the field of entertainment equipment technology, and in particular to a base assembly and a swing chair. Background Technology

[0002] A swing chair is a recreational device that combines leisure and entertainment functions with seating attributes. It is supported by a base, and the rocker arm drives the seat to sway, thus realizing the entertainment of swinging.

[0003] In related technologies, the base includes multiple interconnected tubes, and the connections between the tubes are prone to loosening, causing the base to wobble and fail to stably support the swing chair. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a base assembly and a swing chair to solve the problem that the base of the swing chair in the prior art is prone to shaking and thus cannot provide stable support.

[0005] The technical solution adopted by this utility model to solve its technical problem is a base assembly for connecting with the support assembly of a swing chair, comprising: A first pipe fitting and a second pipe fitting, both of which are connected to the support assembly. The first pipe fitting includes a main body section and an insertion section connected to each other. The free end of the main body section is connected to the support assembly, and the free end of the insertion section is inserted into the second pipe fitting. A connector is fitted outside the connection between the first pipe and the second pipe. The connector has a first abutting part and a second abutting part. The first abutting part abuts against the outer wall surface of the second pipe and supports the second pipe radially. The second abutting part abuts against the outer wall surface of the main body segment and supports the main body segment radially.

[0006] This utility model has at least the following beneficial effects: The connector is fitted outside the connection between the first and second pipes, so that the first abutting part of the connector abuts radially against the outer wall of the second pipe, while the second abutting part of the connector abuts radially against the outer wall of the main body section. This allows the connector to support the second pipe and the main body section radially at the same time, so that the connector, the first pipe, and the second pipe are subjected to force together. This avoids excessive force between the first and second pipes, which could cause them to loosen. It also solves the problem of the base assembly being prone to shaking, and allows the base assembly to support the swing chair more stably.

[0007] Furthermore, along the axial direction of the insertion segment, the connector includes a first connecting segment, a second connecting segment, and a third connecting segment. The first connecting segment and the second connecting segment are both sleeved outside the second pipe fitting, and the third connecting segment is sleeved outside the main body segment.

[0010] Furthermore, the end of the rib facing away from the inner wall of the connector is provided with a third abutting surface, which abuts against the outer wall of the insertion section.

[0011] Furthermore, the rib includes a body portion and a guide portion. The body portion has a first side surface and a second side surface that are disposed opposite to each other along the axial direction of the insertion section. The guide portion is disposed on the second side surface. The first abutting surface is formed on the first side surface, and the second abutting surface is formed on the side of the guide portion opposite to the body portion. Along the direction from the main body segment toward the insertion segment, both the outer wall surface of the transition segment and the second abutment surface gradually extend inward.

[0012] Furthermore, along the circumferential direction of the insertion segment, a plurality of the protruding ribs are provided on the inner wall surface of the connector, and two adjacent protruding ribs are connected or separated from each other, and a space is formed between two separated protruding ribs for the protruding ribs to deform.

[0013] Furthermore, the inner wall surface of the connector is provided with a plurality of protrusions arranged in the circumferential direction, and the second abutting portion is formed on the protrusions; the plurality of protrusions abut against the outer wall surface of the main body segment.

[0024] Please refer to Figure 1 This embodiment discloses a swing chair, including a base assembly 100, a support assembly 200, and a swing assembly 300. The swing assembly 300 includes a rocker arm 320 and a seat 310, and the seat 310 can be swung by rotating the rocker arm 320. The support assembly 200 includes a fixed seat 210 connected to the rocker arm 320 for supporting the swing assembly 300. The base assembly 100 is connected to the fixed seat 210 for supporting the swing assembly 300 and the support assembly 200. The detailed structure of the base assembly 100 is described below.

[0025] Please refer to Figures 2 to 8 This embodiment discloses a base assembly 100 for connection with a support assembly 200 of a swing chair, including a first tube 110, a second tube 120, and a connector 130. Both the first tube 110 and the second tube 120 are connected to the support assembly 200. The first tube 110 includes a main body section 111 and an insertion section 112 connected to each other. The free end of the main body section 111 is connected to the support assembly 200, and the free end of the insertion section 112 is inserted into the second tube 120. The connector 130 is sleeved outside the connection between the first tube 110 and the second tube 120. The connector 130 has a first abutment portion 1301 and a second abutment portion 1302. The first abutment portion 1301 abuts against the outer wall surface of the second tube 120 and supports the second tube 120 radially, while the second abutment portion 1302 abuts against the outer wall surface of the main body section 111 and supports the main body section 111 radially.

[0026] Specifically, both the first pipe fitting 110 and the second pipe fitting 120 are hollow structures. One end of the second pipe fitting 120 is bent upwards and connected to the fixed seat 210 of the support assembly 200. The first pipe fitting 110 includes a main body section 111 and an insertion section 112. The end of the main body section 111 facing away from the insertion section 112 (the free end) is bent upwards and connected to the fixed seat 210 of the support assembly 200, so that the first pipe fitting 110 and the second pipe fitting 120 jointly support the fixed seat 210 and the swing assembly 300 connected to the fixed seat 210. The outer diameter of the insertion section 112 is approximately equal to the inner diameter of the second pipe fitting 120, so that the insertion section 112 can extend into the interior of the second pipe fitting 120 from the end of the second pipe fitting 120 facing away from the support assembly 200, thereby realizing the connection between the first pipe fitting 110 and the second pipe fitting 120.

[0027] Importantly, in this embodiment, a connector 130 is provided at the connection between the first pipe 110 and the second pipe 120, so that the first abutting part 1301 of the connector 130 abuts radially against the outer wall surface of the second pipe 120, while the second abutting part 1302 of the connector 130 abuts radially against the outer wall surface of the main body segment 111. This allows the connector 130 to simultaneously support the second pipe 120 and the main body segment 111 radially, ultimately causing the connector 130, the first pipe 110, and the second pipe 120 to bear force together. This avoids excessive force between the first pipe 110 and the second pipe 120, which could cause them to loosen. This solves the problem of the base assembly 100 being prone to wobbling, allowing the base assembly 100 to support the swing chair more stably.

[0028] Further, please refer to Figure 6 and Figure 8 Along the axial direction of the insertion section 112, the connector 130 includes a first connecting section 1303, a second connecting section 1304, and a third connecting section 1305. The first connecting section 1303 and the second connecting section 1304 are both sleeved outside the second pipe fitting 120, and the third connecting section 1305 is sleeved outside the main body section 111. Along the radial direction of the insertion section 112, the projection of the second connecting section 1304 coincides with the projection of the insertion section 112. It should be noted that in... Figure 5 and Figure 6 In the middle, the insertion section 112 did not fully extend into the second pipe fitting 120. Figure 7 and Figure 8 In the middle, the insertion section 112 extends into the connector 130, but has not yet begun to enter the second pipe 120.

[0029] Specifically, the connector 130 includes, along the axial direction, a first connecting segment 1303, a second connecting segment 1304, and a third connecting segment 1305. The second connecting segment 1304 overlaps with the insertion segment 112 radially. One end of the second connecting segment 1304 extends towards the second pipe fitting 120 to form the first connecting segment 1303, which connects to the second pipe fitting 120. The other end of the second connecting segment 1304 extends towards the main body segment 111 to form the third connecting segment 1305, which connects to the main body segment 111. This allows the connector 130 to not only cover the insertion segment 112 but also extend at both ends to partially cover the second pipe fitting 120 and the main body segment 111. This ensures that the second pipe fitting 120 (including the overlapping and non-overlapping portions), the insertion segment 112, the main body segment 111, and the connector 130 share the load, further improving the connection strength between the first pipe fitting 110 and the second pipe fitting 120 and preventing loosening at the connection between the insertion segment 112 and the second pipe fitting 120.

[0030] Please refer to Figure 4 and Figure 8 In this embodiment, the second pipe fitting 120 has a first end face facing away from the support assembly 200; a transition section 113 is also provided between the insertion section 112 and the main body section 111; a rib 131 is provided on the inner wall surface of the connector 130, the rib 131 has a first abutting surface and a second abutting surface arranged opposite to each other along the axial direction of the insertion section 112, the first abutting surface abuts against the first end face, and the second abutting surface abuts against the outer wall surface of the transition section 113. Exemplarily, the rib 131 is provided on the inner wall of the connector 130 and located at the connection between the second connecting section 1304 and the third connecting section 1305.

[0031] Specifically, the rib 131 has a first abutting surface and a second abutting surface arranged axially opposite to each other. The first abutting surface abuts against the first end face of the second pipe fitting 120, and the second abutting surface abuts against the outer wall surface of the transition section 113. This arrangement achieves at least the following technical effects: First, it prevents the first end face from abutting against the outer wall surface of the transition section 113, preventing stress concentration at the abutting point of the two surfaces due to insufficient contact area caused by the different curvatures of the two surfaces; second, the rib 131 increases the contact area between the connector 130, the first pipe fitting 110, and the second pipe fitting 120, thereby improving the connection strength between the first pipe fitting 110, the second pipe fitting 120, and the connector 130.

[0032] Furthermore, the end of the rib 131 facing away from the inner wall of the connector 130 is provided with a third abutment surface, which abuts against the outer wall of the insertion section 112. Specifically, the third abutment surface abuts against the outer wall of the insertion section 112 radially to further increase the contact area between the connector 130 and the first pipe fitting 110, thereby improving the connection strength between the first pipe fitting 110, the second pipe fitting 120, and the connector 130. At the same time, the rib 131 is more easily deformed than the inner wall of the connector 130, and can undergo a certain deformation when abutting against the insertion section 112, so as to allow the insertion section 112 and the connector 130 to have larger dimensional tolerances and reduce the requirements for processing technology.

[0033] Please refer to Figure 4 In this embodiment, the rib 131 includes a body portion 1311 and a guide portion 1312. The body portion 1311 has a first side surface and a second side surface that are disposed opposite each other along the axial direction of the insertion section 112. The guide portion 1312 is disposed on the second side surface. A first abutting surface is formed on the first side surface, and a second abutting surface is formed on the side of the guide portion 1312 that is away from the body portion 1311. Along the direction from the body portion 111 toward the insertion section 112, the outer wall surface of the transition section 113 and the second abutting surface both gradually extend inward.

[0034] Specifically, the second abutment surface gradually extends inward along the main body section 111 toward the insertion section 112. When the insertion section 112 extends axially into the second pipe fitting 120, the second abutment surface of the guide portion 1312 can guide the insertion section 112 to gradually enter the second pipe fitting 120 for quick assembly. At the same time, the outer wall surface of the transition section 113 gradually extends inward along the main body section 111 toward the insertion section 112. After the insertion section 112 is inserted into the second pipe fitting 120, the outer wall surface of the transition section 113 fits against the second abutment surface to further increase the contact area between the first pipe fitting 110 and the connector 130, thereby improving the connection strength between the first pipe fitting 110 and the connector 130.

[0035] Meanwhile, the outer diameter of the second fitting 120 is equal to the outer diameter of the main body section 111, so that the appearance of the first fitting 110 and the second fitting 120 after connection is more regular. The outer diameter of the insertion section 112 is smaller than the outer diameters of the second fitting 120 and the main body section 111, resulting in a step with a sudden change in outer diameter at the connection between the insertion section 112 and the main body section 111. In order to avoid stress concentration at this step and damage to the first fitting 110, a transition section 113 is provided between the insertion section 112 and the main body section 111. One end of the transition section 113 is connected to the main body section 111 with a larger outer diameter, and the other end is connected to the insertion section 112 with a smaller outer diameter. This allows the outer diameter of the main body section 111 to change evenly from the insertion section 112 to avoid stress concentration.

[0036] In some other embodiments, a first abutting surface is formed on a first side of the rib 131, and a second abutting surface is formed on a second side of the rib 131.

[0037] Please continue to refer to Figure 4 In this embodiment, a plurality of protruding ribs 131 are provided on the inner wall surface of the connector 130 along the circumferential direction of the insertion section 112, and adjacent two protruding ribs 131 are connected or separated from each other, with a space formed between the two separated protruding ribs 131 for deformation of the protruding ribs 131. Exemplarily, the inner wall surface of the connector 130 is provided with a plurality of first protruding ribs and a plurality of second protruding ribs, which are arranged radially opposite each other or alternately arranged circumferentially; the second side of the first protruding rib is provided with a guide portion 1312, and the second side of the second protruding rib forms a second abutment surface; adjacent two first protruding ribs are separated from each other, thereby creating a gap between the two first protruding ribs to allow deformation when the insertion end is inserted into the second pipe fitting 120, facilitating assembly and providing pre-tightening force generated by deformation after assembly, thereby improving the connection strength between the insertion section 112 and the second pipe fitting 120. Meanwhile, adjacent two second protruding ribs are connected to each other, and because they do not have a large deformation space, they cannot generate large deformation, thus providing more stable support for the insertion section 112. The above not only facilitates the assembly of the insertion section 112 and the second pipe fitting 120, but also enhances the connection strength between the two.

[0038] It should be noted that if the inner wall of the connector 130 is required to fit completely with the outer wall of the main body segment 111, the dimensional tolerances of the connector 130 and the main body segment 111 need to be controlled within a very small range, which requires high processing technology.

[0039] Based on this, please continue to refer to Figure 4 In this embodiment, a plurality of protrusions 132 arranged circumferentially are provided on the inner wall surface of the connector 130, and a second abutment portion 1302 is formed on the protrusions 132; the plurality of protrusions 132 abut against the outer wall surface of the main body segment 111. For example, the protrusions 132 are provided on the inner wall surface of the third connecting segment 1305. When the main body segment 111 extends into the third connecting segment 1305, the outer wall surface of the main body segment 111 can compress the protrusions 132, causing the protrusions 132 to undergo a certain deformation and abut against the outer wall surface of the main body segment 111, thereby allowing the dimensional tolerances of the connector 130 and the main body segment 111 to fluctuate within a larger range and reducing the requirements for the processing technology.

[0040] In this embodiment, the connector 130 is made of a material that is more easily deformed than the first pipe 110 and the second pipe 120. For example, the first pipe 110 and the second pipe 120 are made of metal to provide sufficient support, while the connector 130 is made of plastic so that when it is connected to the first pipe 110 and the second pipe 120, the protrusion 132 and the rib 131 can deform to a certain extent, so that the connector 130, the first pipe 110 and the second pipe 120 are connected more tightly.

[0041] In some other embodiments, the first abutment portion 1301 is formed on the inner wall surface of the first connecting segment 1303 and the second connecting segment 1304, and the second abutment portion 1302 is formed on the inner wall surface of the third connecting segment 1305; the outer wall surface of the insertion segment 112 abuts against the inner wall surface of the second pipe fitting 120; the inner wall surfaces of the first connecting segment 1303 and the second connecting segment 1304 both abut against the outer wall surface of the second pipe fitting 120, and the inner wall surface of the third connecting segment 1305 abuts against the outer wall surface of the main body segment 111. The abutment of the contact surfaces of the first pipe fitting 110, the second pipe fitting 120, and the connector 130 can be understood as partial or complete abutment of two surfaces (i.e., two surfaces are in contact). While this increases the requirements of the processing technology, it increases the contact area of ​​the connector 130, the first pipe fitting 110, and the second pipe fitting 120, thereby improving the connection strength.

[0042] Please refer to Figure 8 In this embodiment, the inner wall surface of the connector 130 is further provided with a locking protrusion 133; the second pipe 120 is provided with a locking hole 121, and the locking protrusion 133 extends into the locking hole 121 to lock the relative movement between the connector 130 and the second pipe 120. Specifically, the locking protrusion 133 can extend radially into the locking hole 121 and abut against the locking hole 121 axially, thereby achieving axial locking of the second pipe 120 and the connector 130.

[0043] In this embodiment, the first pipe 110, the second pipe 120, and the connector 130 are all provided with support members 140, and each support member 140 is in contact with the working surface to jointly support the base assembly 100. Specifically, the support member 140 is provided on the connector 130 so that the support members 140 on the connector 130, the first pipe 110, and the second pipe 120 together support the entire swing chair, preventing the base assembly 100 from being unstable due to the area where the connector 130 is located being suspended. For example, the support member 140 can be configured as a rolling caster or a fixed support column, etc.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
