CN-224228523-U - Bottom beam profile for automatic door

Abstract

The utility model belongs to the technical field of electric retractable doors, and particularly relates to a bottom beam section for an automatic door, wherein a supporting roller installation cavity is arranged at the lower part of the cross section of the bottom beam section, a downward opening is formed in the supporting roller installation cavity, an upper guide groove and a lower guide groove are formed in the same side of the supporting roller installation cavity, openings are formed in the upper guide groove and the lower guide groove, and the openings of the upper guide groove and the lower guide groove face to the outer side. Compared with the prior art, the bottom beam section bar for the automatic door is more reasonable, and because the upper circulating rope guide groove and the lower circulating rope guide groove are opened to the side surfaces, the bottom surfaces of the guide grooves can support the circulating ropes and cannot be exposed, the circulating ropes are prevented from being damaged, the protection effect is achieved, and meanwhile, the appearance of the telescopic door is more attractive.

Description

Bottom beam profile for automatic door Technical Field The utility model relates to a bottom beam section bar for an automatic door, and belongs to the technical field of electric retractable doors. Background The electric telescopic door mainly comprises a door body, a driver and a control system, wherein the door body of the telescopic door is generally made of aluminum alloy sections, has large flexible telescopic travel, and is widely applicable to various occasions and used as a movable enclosing wall. The application discloses an electric sliding door transmission structure and a sliding door, which are applied by the inventor in 2022 and have the patent number of CN202210747579.2, wherein the motion of a door body can be transmitted to a power transmission bracket through a circulating rope wheel and a circulating rope, and then the next door body is directly pushed to move through the power transmission bracket, so that the quick and stable motion of the sliding door is realized. The working principle is described in detail in the cited patent and is not described too much here. Because the lower part of the original section is an integral supporting roller mounting cavity for arranging the supporting roller of the main driving fixing bracket, no special circulating rope mounting cavity exists, and therefore, the circulating rope is exposed, is easy to damage and is not attractive. The applicant then improves the profile and claims the utility model patent number 2023201423192, as shown in fig. 1 and 2, although the circulating rope installation cavity is arranged, the problems are solved to a certain extent, the guiding and protecting effects are achieved, the opening of the lower cavity is downward, the circulating rope is easily hung and exposed from the opening at the lower part, and the circulating rope is not attractive and is easily damaged. Disclosure of utility model According to the defects in the prior art, the utility model aims to provide a bottom beam section bar for an automatic door, which is provided with two lateral circulating rope guide grooves so as to solve the problems. The utility model relates to a bottom beam section for an automatic door, wherein the lower part of the cross section of the bottom beam section is a supporting roller installation cavity, the supporting roller installation cavity is provided with a downward opening, the same side of the supporting roller installation cavity is provided with an upper guide groove and a lower guide groove, the upper guide groove and the lower guide groove are also provided with openings, and the openings of the upper guide groove and the lower guide groove face to the outer side. In the scheme of the utility model, a sliding block is arranged in the upper guide groove and is linked with the circulating rope, the upper section of the circulating rope is also positioned in the upper guide groove, the opening on the upper guide groove is used for connecting the sliding block with a connecting piece, and the sliding block is connected with the next door body through the connecting piece. The lower section of the circulating rope is positioned in the lower guide groove, and the end head of the circulating rope is fixed on the rope end fixing frame. Because the upper circulating rope guide groove and the lower circulating rope guide groove are opened to the side face, the bottom surface of the guide groove can support the circulating rope and cannot be exposed, and the novel circulating rope guide device has the protection and attractive effects. Preferably, the sum of the heights of the upper guide groove and the lower guide groove is consistent with the height of the supporting roller installation cavity. The upper guide groove is provided with a sliding block, so that the height of the upper guide groove is larger than that of the lower guide groove. Preferably, the widths of the upper guide groove and the lower guide groove are equal. Compared with the prior art, the utility model has the following beneficial effects: Compared with the prior art, the bottom beam section bar for the automatic door is more reasonable, and because the upper circulating rope guide groove and the lower circulating rope guide groove are opened to the side surfaces, the bottom surfaces of the guide grooves can support the circulating ropes and cannot be exposed, the circulating ropes are prevented from being damaged, the protection effect is achieved, and meanwhile, the appearance of the telescopic door is more attractive.
