[0036] Reference Figure 1-Figure 3 The basic embodiment of the first aspect of the present invention provides a connecting component, including:
[0037] The first bracket 100 is provided with a card slot 110, and the card slot 110 is recessed in the first bracket 100;
[0038] The second bracket 200 is provided with a buckle 210 that cooperates with the slot 110, and the buckle 210 protrudes from the second bracket 200 along the first direction;
[0039] The first bracket 100 and the second bracket 200 have at least one slot 130 extending along the second direction on one side, and at least one plug-in 260 on the other side. The plug-in 260 can be inserted into the corresponding slot 130 .
[0040] According to the embodiment of the present invention, by such a setting, at least some of the following effects can be achieved: the second bracket 200 is inserted into the first bracket 100 along the second direction, so that the plug-in 260 can correspond to the slot 130, so that the range of movement of the second bracket 200 is limited to the second direction; through the mutual cooperation of the buckle 210 structure protruding from the second bracket 200 and the card slot 110 structure recessed in the first bracket 100, the first direction and the second direction are two directions facing different directions, so that the buckle 210 is clamped on the card slot 110, and the two cooperate with each other, so that it can limit the movement of the second bracket 200 in the second direction. Combined with the cooperation of the plug-in 260 and the slot 130, the second bracket 200 can be fixed on the first bracket 100 without the use of other connecting structures, which is convenient for installation.
[0041] It can be understood that the first direction and the second direction are any two directions that are not parallel to each other. Preferably, the first direction and the second direction are perpendicular to each other.
[0042] It is understandable that the slot 130 may be a rectangular slot, a circular slot or an irregularly shaped slot.
[0043] In some embodiments, the insert 260 is provided with a positioning rib 220, and the slot 130 is provided with a groove 131 that cooperates with the positioning rib 220. The cooperation between the positioning rib 220 and the groove 131 can improve the installation stability between the slot 130 and the insert 260. The cooperation between the positioning rib 220 and the groove 131 can also act as a limiter, increasing the contact area between the insert 260 and the slot 130, and facilitating installation. The positioning rib 220 can provide guiding, positioning, and support functions, ensuring accurate and stable assembly.
[0044] In some embodiments, a reinforcing rib 230 is provided between the insert 260 and the second bracket 200. The reinforcing rib 230 enhances the durability and rigidity of the product: the rib 230 can increase the rigidity and strength of the plastic part and reduce deformation or distortion caused by stress without increasing the wall thickness of the part, thereby saving material, reducing weight, and lowering costs. It also provides flow guidance: the rib 230 can serve as an internal flow channel, helping the plastic melt flow into thin-walled or hard-to-fill parts of the product, improving plastic flow during the injection molding process and ensuring mold cavity filling. It also assists in assembly: when assembled with other parts, the rib 230 can provide guidance, positioning, and support functions to ensure accurate and stable assembly. It also prevents warping: the rib 230 helps reduce uneven stress caused by varying wall thickness, thereby preventing product warping. It also reduces material usage: by properly designing the rib 230, the rigidity of the part can be increased without increasing the wall thickness, thereby reducing material usage. It also provides structural reinforcement: adding ribs 230 to certain areas of the plastic part, such as corners or sidewalls, can locally increase the rigidity of the product, especially when subjected to twisting or bending loads.
[0045] In some embodiments, the second bracket 200 is formed as an inverted U-shaped block, and the first bracket 100 is provided with a U-shaped groove 120 that supports the bottom and sides of the inverted U-shaped block. The U-shaped configuration of the second bracket 200 effectively increases the lateral surface area of the second bracket 200. Conversely, the corresponding lateral surface area of the U-shaped groove 120 is also increased, resulting in a larger contact area between the two, which facilitates the stability of the installation of the second bracket 200.
[0046] In some embodiments, the second bracket 200 is provided with an avoidance groove 240, and the slot 130 can pass through the avoidance groove 240. By providing the avoidance groove 240, each position of the second bracket 200 can pass through the slot 130 to prevent interference.
[0047] In some embodiments, the second bracket 200 is provided with a mounting hole 250. The mounting hole 250 is used to mount a chair back or other chair components.
[0048] Furthermore, the mounting hole 250 may be a threaded hole.
[0049] In some embodiments, the width of the buckle 210 gradually decreases along the second direction. Due to the varying width of the buckle 210, when the buckle 210 moves along the second direction, the edge of the buckle 210 abuts the first bracket 100, and the buckle 210 acts as a guide, causing the second bracket 200 to slightly deform and pass through the edge of the first bracket 100, so that the buckle 210 and the slot 110 can cooperate with each other.
[0050] It can be understood that the width of the buckle is the distance of the buckle along the first direction.
[0051] In some embodiments, multiple slots 130 are located in different planes. Referring to the positions of the slots 130 in the accompanying drawings, the slots 130 may not only have a left-right positional deviation, but also a front-back positional deviation. By providing slots 130 in different positions, the overall installation stability can be increased.
[0052] In some embodiments, the slot 130 includes a first slot and at least two second slots. The first slot and the second slot are both located at the top of the second bracket, with the first slot located in the middle of the second bracket and the second slots located on either side of the first slot. By providing three different slots and the deviation in the left and right positions of the three slots, a better connection can be provided to the top.
[0053] In some embodiments, the slot 130 further includes at least two third slots, each of which is located on the side of the second bracket. The third slots are offset from the first slots in the front-to-back direction, and the third slots are located on the side of the second bracket to provide a better connection and enhance installation stability.
[0054] In some embodiments, the second bracket 200 has an inner cavity, and the buckle 210, the plug 260, or the slot 130 are all disposed in the inner cavity. The second bracket 200 is entirely injection molded, and the inner cavity structure can reduce a large amount of material loss. The buckle 210, the plug 260, or the slot 130 are disposed in the inner cavity, which can effectively utilize the internal space.
[0055] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", "extended embodiment" may be used to describe several embodiments of the present utility model. The specific features, structures, materials or characteristics in several embodiments may be combined in accordance with the principles and purposes of the present utility model.
[0056] Although some embodiments of the present invention have been shown and described in this specification, the present invention should not be limited to the above embodiments. As long as the technical effects of the present invention are achieved by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations to these embodiments within the spirit and principles disclosed in the present invention and without departing from the principles and purpose of the present invention should be included in the scope of protection disclosed in the present invention and should be deemed to fall within the scope of protection of the present invention.
