[0027] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.
[0028] See Figure Figure 1 , Figure 3 and Figure 4 As shown, an embodiment of the utility model provides a frame structure of a sliding door, including a frame profile 1 arranged around a door body 2 of the sliding door, wherein at least one hollow cavity 3 is arranged in the frame profile 1 along its axial direction.
[0029] This embodiment improves the inner wall structure of the hollow cavity, thereby reducing the production cost of the profile while ensuring the strength of the profile.
[0030] Specifically, a plurality of strip grooves 31 arranged at a predetermined interval are provided along the inside of the hollow cavity 3, the axial direction of the strip grooves 31 is consistent with the axial direction of the hollow cavity 3, and the gap between two adjacent strip grooves 31 forms a supporting protrusion 32, and the distance from the top surface of the supporting protrusion 32 to the outer surface of the frame profile 1 is a first thickness, and the first thickness is not less than 1.8 mm.
[0031] The working principle of the utility model is that at least one hollow cavity 3 is provided in the frame profile, and the inner wall of the hollow cavity 3 is provided with a plurality of strip grooves 31, and the gaps between adjacent strip grooves 31 form support protrusions 32. In particular, the top surface of the support protrusion 32 and the bottom surface of the strip groove 31 have different wall thicknesses to the outer side profile of the frame profile 1, and the distance from the support protrusion 32 to the outer side of the frame profile 1 is the first thickness, and the first thickness is not less than 1.8 mm to meet the requirements of the wall thickness of the frame profile 1, so the structural strength of the frame profile 1 can be guaranteed.
[0032] Compared with the single wall thickness structure of the prior art, it can effectively save the production materials of the profile while ensuring the structural strength of the profile, thereby reducing the production cost of the frame structure.
[0033] Preferably, the distance from the bottom surface of the strip groove 31 to the outer side surface of the frame profile 1 is the second thickness, and the second thickness is less than 2.0 mm. In order to save the preparation cost of the frame profile 1, the second thickness is limited to less than 2.0 mm.
[0034] More preferably, the second thickness is in the range of 1.2-1.4 mm. When the second thickness is less than 1.2 mm, since the bottom surface of the strip groove 31 is the thin part of the hollow cavity 3, when the thickness is less than 1.2 mm, it will affect the structural strength of the profile, causing this part to be easily bent and deformed. When the second thickness is greater than 1.4 mm, the thickness is too thick, which will cause waste and increase the production cost of the profile.
[0035] Preferably, the cross section of the strip groove 31 is a V-shaped or arc-shaped structure. In order to ensure the structural strength of the strip groove 31, the cross section structure is selected to be a V-shaped or arc-shaped structure.
