The telescopic arm assembly 100 comprises: a fixed arm 110 and an extension arm 120. A through groove 111 is formed in the fixing arm 110 for accommodating the extending arm 120. The extending arm 120 is provided in the through groove 111 on the fixing arm 110, and the extending arm 120 is movable along the through groove 111 and can protrude from either of the opposite ends of the fixing arm 110. In fig. 1 to 3, and in fig. 4 to 6, the extension arms 120 respectively protrude from either of the opposite ends of the fixing arm 110. The telescopic arm assembly 100 has a simple structure, a small self weight and a long stroke of the extending arm 120.

The telescopic arm assembly 100 provided by the embodiment of the application provides an accommodating space for the extending arm 120 by arranging the through groove 111 in the fixed arm 110. The extending arm 120 moves along the through groove 111 and can extend from either of the two opposite ends of the fixed arm 110, so that the extending arm 120 can have a long stroke, and meanwhile, the telescopic arm assembly 100 has the advantages of simple structure, small self weight, small telescopic resistance, larger stroke than that of the traditional telescopic structure, simple structure, small occupied area and convenient movement, and can be used for a telescopic arm assembly 100.

The through groove 111 is arranged inside the fixed arm 110, which is beneficial to the movement of the extending arm 120 in a state of hanging heavy objects, and also enables the gap between the extending arm 120 and the fixed arm 110 to be downward, thereby preventing sand and dust or other sundries from falling into the gap from top to bottom, keeping the gap clean, and prolonging the service life of the telescopic arm assembly 100.

In one embodiment provided by the present invention, the fixing arm 110 includes: a top panel 112 and two side panels 113. Wherein the top plate 112 is located at the top, the two side plates 113 are vertically connected to the bottom surface of the top plate 112, and the two side plates 113 are spaced apart from each other, so that the top plate 112 and the two side plates 113 jointly enclose the through slot 111. The profile of the extension arm 120 is matched to the through slot 111 so that the extension arm 120 can move in the through slot 111 and can protrude from either end of the through slot 111. The structure is simple in structure, convenient to process and high in strength.

The following description will be given taking an example in which the cross-sectional shape of the fixing arm 110 is rectangular.

Further, a guiding structure is provided between the fixed arm 110 and the extending arm 120, so that when the extending arm 120 moves relative to the fixed arm 110, the extending arm 120 can be guided, and the movement of the extending arm 120 can be accurately limited. The structure of the guiding structure may be various, for example, it may be: a plurality of sets of guide members 130 are provided on the inner side walls of the side plates 113, and guide rails 140 matched with the guide members 130 are provided on the outer side walls of the extension arms 120. Of course, the guiding structure may be in other forms, which is not limited in this embodiment. The following description will be given only by way of example in which the guide 130 is provided on the inner side wall of the side plate 113.

Fig. 7 is a partial structural view of an arm in a telescopic arm assembly according to the present invention, and fig. 7 shows a structure of a guide 130, see fig. 7. In the above embodiment, the number of the guide members 130 may be plural groups to ensure that the guide rail 140 does not fall off the fixing arm 110 away from the guide members 130. Each set of guides 130 comprises: the double-layer rollers 131 arranged up and down play a role in limiting the guide rail 140 by arranging the guide rail 140 between the double-layer rollers 131, and the rollers 131 positioned at the lower layer can also support the guide rail 140. The friction between the upper and lower surfaces of the guide rail 140 and the rollers 131 of the upper and lower layers is reduced by rolling friction, so that the friction resistance of the guide rail 140 during the movement process is reduced. The guide structure of the roller 131 has large bearing capacity, and the structure is convenient to install and adjust, has low requirements on the machining precision and the service environment during working, and is easy to maintain.

The number of the rollers 131 in each set of the guide members 130 may be set according to requirements, and for example, may include one upper roller 131 and two lower rollers 131, or two upper rollers 131 and one lower roller 131.
