[0033] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0034] like Figure 1-6 As shown, this embodiment discloses a rotary spraying carrier with a concealed handle housing.

[0035] A rotary spraying carrier with a concealed handle housing includes a bracket 100, several annular hanging arms 200 arranged vertically on the bracket 100, and a plurality of bracket assemblies 300 arranged circumferentially on the annular hanging arms 200; the annular hanging arms 200 are provided with a plurality of fastening slots 201 arranged circumferentially, and the bracket assemblies 300 are detachably mounted to the annular hanging arms 200 through the fastening slots 201.

[0036] The bracket assembly 300 is provided with a buckle 321 that can limit the assembly to the buckle 411 inside the handle housing 400.

[0037] The above is the basic scheme of this embodiment.

[0038] Specific reference Figure 1 and Figure 2As shown, multiple annular hanging arms 200 are provided and spaced apart in the vertical direction. Meanwhile, bracket assemblies 300 are arranged circumferentially on the annular hanging arms 200. Each bracket assembly 300 carries a handle housing 400. That is to say, one annular hanging arm 200 can carry multiple handle housings 400, and a carrier can be provided with multiple annular hanging arms 200 as needed, thereby increasing the number of handle housings 400 on the carrier and improving the spraying effect.

[0039] When an external rotating device drives the carrier to rotate, the bracket assembly 300 drives the handle housing 400 to rotate synchronously, thereby achieving rotary spraying of the handle housing 400.

[0040] In this embodiment, multiple hangers 100 are provided and arranged circumferentially along the annular hanging arm 200.

[0041] In this embodiment, the lower end of the hanger 100 is mounted on an annular drive ring 500 for connection with external rotating equipment.

[0042] In this embodiment, to ensure the stable installation of the handle housing 400, the bracket assembly 300 is installed to the annular hanging arm 200 through the buckle groove 201, and the handle housing 400 is connected to the bracket assembly 300 through the buckle rib 411, so that the handle housing 400 does not directly contact the rotating annular hanging arm 200, but is supported by the bracket assembly 300, which ensures the stability of the handle housing 400 during rotation and makes it less prone to shaking.

[0043] To simplify the installation process, in this embodiment, the bracket assembly 300 includes a receiving bracket 310 connected to the buckle groove 201, and a positioning fixture 320 slidably mounted on the receiving bracket 310, wherein the buckle 321 protrudes from the outer periphery of the positioning fixture 320.

[0044] Specific reference Figure 3 As shown, the outer surface of the concealed handle on the car is designed to be flat to form an integral part with the door, and a side panel 410 is provided around its outer perimeter. The side panel 410 and the end face form a groove structure at the bottom, and multiple fastening ribs 411 are provided on the inner wall of the side panel 410. During installation, the support bracket 310 is installed on the fastening groove 201 of the annular hanging arm 200. At the same time, the upper part of the positioning fixture 320 is placed into the groove. The fastening position 321 and the fastening ribs 411 on the outer periphery of the positioning fixture 320 are connected to form a connection between the handle housing 400 and the positioning fixture 320. Then, the positioning fixture 320 is installed on the support bracket 310 to complete the installation of the handle housing 400 and the carrier.

[0045] In this embodiment, the buckle 411 is an L-shaped rib, and a gap is formed between the top surfaces of the handle housing 400 in the horizontal direction. The buckle 321 slides into the gap, thereby limiting the movement of the handle housing 400 in the vertical direction.

[0046] To avoid contact between the bracket assembly 300 and the outer surface of the handle housing 400, in this embodiment, the slot of the handle housing 400 is able to cover at least the upper surface of the positioning fixture 320. That is to say, the bracket assembly 300 and at least the positioning fixture 320 will not be exposed to the outside of the handle housing 400.

[0047] Based on the above configuration, when the handle housing 400 is installed on the vehicle, the handle housing 400 is suspended on the annular hanging arm 200, and the outer surface to be painted does not come into contact with the vehicle, thus enabling complete painting.

[0048] Specifically, the receiving support 310 includes a lower part with a hanging arm groove 311 and an upper part with a sliding groove 312;

[0049] The bottom of the hanging arm groove 311 is provided with a latching protrusion 313 that cooperates with the buckle groove 201.

[0050] Specific reference Figure 4 As shown, the main body of the support 310 is a rectangular block structure. A hanging arm groove 311 is provided on the lower part facing the annular hanging arm 200. The support 310 is installed from the outside of the annular hanging arm 200. The opening of the hanging arm groove 311 is located on the side. A locking protrusion 313 that cooperates with the fastening groove 201 is provided at the bottom of the groove. When the annular hanging arm 200 is inserted into the hanging arm groove 311, the locking protrusion 313 is inserted into the fastening groove 201, thus positioning the support 310 and the annular hanging arm 200.

[0051] Preferably, the opening of the hanging arm groove 311 is set as a flared opening.

[0052] In other words, the upper and lower end faces of the hanging arm groove 311 are set as symmetrical inclined surfaces to guide the annular hanging arm 200, so that the annular hanging arm 200 can be smoothly inserted into the hanging arm groove 311.

[0053] The upper part of the support 310 is provided with a slide groove 312 for installing the positioning fixture 320.

[0054] Preferably, in this embodiment, in order for the protrusion 313 to smoothly enter the groove 201, the opening of the groove 201 is set to be flared.

[0055] The two beveled surfaces of the flared opening guide the snap protrusion 313, allowing it to smoothly enter the snap groove 201.

[0056] To ensure the connection between the receiving support 310 and the annular hanging arm 200, in this embodiment, the lower part of the receiving support 310 extends toward the annular hanging arm 200 and is provided with an installation arm 314, the end of which is provided as a downward-facing installation hook 315.

[0057] Specific reference Figure 4 As shown, the mounting arms 314 are located at both ends of the main body of the receiving bracket 310 along its length. They face the side of the annular hanging arm 200, and their length is just enough for the mounting hook 315 to hook the inner ring of the annular hanging arm 200.

[0058] Based on the above configuration, the bottom of the hanging arm groove 311 abuts against the outer ring of the annular hanging arm 200, and the mounting hook 315 abuts against the inner ring of the annular hanging arm 200, thereby limiting the radial movement of the annular hanging arm 200 and the support bracket 310. Combined with the locking protrusion 313 and the buckle groove 201, the support bracket 310 is completely positioned on the annular hanging arm 200.

[0059] In this embodiment, the slide groove 312 is an inverted T-shaped groove with its opening extending to the top surface of the support 310; the bottom of the positioning fixture 320 is provided with a T-shaped slide rail 322 that mates with the slide groove 312.

[0060] Furthermore, to ensure the installation position of the positioning fixture 320 on the support 310, only one end of the T-slot along the sliding direction is set as a complete T-shaped opening for the T-shaped slide rail 322 to slide into, while the other end is set as a closed or partially closed end to stop the T-shaped slide rail 322.

[0061] In order to allow the T-shaped slide rail 322 to slide smoothly into the T-shaped groove, in this embodiment, guide bars 323 are provided at both ends of the T-shaped slide rail 322 along the sliding direction, and the ends of the two guide bars 323 are both set as wedge-shaped guide surfaces.

[0062] Specific reference Figure 5 As shown, the width of the guide bar 323 is not greater than the width of the groove at the narrowest position of the slide groove 312.

[0063] In this embodiment, a gap a is left between the positioning fixture 320 and the receiving support 310.

[0064] Specific reference Figure 6 As shown, the vertical length of the T-shaped slide rail 322 is greater than the vertical depth of the slide groove 312, thus leaving a gap a between the upper end face of the positioning fixture 320 and the lower end face of the main body of the support 310. When the T-shaped slide rail 322 slides into the slide groove 312, the positioning fixture 320 and the main body of the support 310 do not contact each other, thereby reducing friction and making the sliding smoother.

[0065] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
