Abstract

The utility model relates to an improved rail structure of the lorry awning frame, which mainly comprises an inclined grid sheet, a vertical slide shaft, a horizontal slide shaft, an elevating slide block and a horizontal slide block, wherein, the elevating slide block is sheathed on the vertical slide shaft; the horizontal slide block is sheathed at the lower part of the vertical slide shaft. The inner end surfaces of the elevating slide block and the horizontal slide block are equally provided with three convex parts so that the elevating slide block is contacted with the vertical slide shaft, a horizontal slide block and the horizontal slide shaft bythree points; thus, the friction is decreased and collision is avoided.

Description

Improved rail structure of lorry awning frame

The utility model relates to the improved structure of slide rail in a kind of paulin frame of lorry.

The canopy of lorry is located at the top of seat-box behind the car body usually, and this canopy serves as maximum with the dual-purpose type slide rail canopy that can draw in, draw back.Its structure as shown in Figure 1, tilted grating (11) is fixing in the skeleton upper end with screw (115), fixed with three packing rings (112) and rivet (114) at two tilted grating infalls, be provided with lifting slider (13) on erect sliding shaft (12), it is the cross sliding clock (14) of track with cross sliding shaft (15) that the below of each erect sliding shaft (12) is provided with one.As shown in Figures 2 and 3, this lifting slider (13) is to be linked on the erect sliding shaft (12) with inner end surface (131), which is provided with an axostylus axostyle (132), and with packing ring (112) and screw (113) tilted grating (11) is fixed on this axostylus axostyle (132).Again as shown in Figure 4 and Figure 5, this cross sliding clock (14) has two kinds of forms, slide against on the cross sliding shaft (15) with its inner end surface (140), its top is provided with one and inserts axle (145), and be engaged in the hollow tube bottom of erect sliding shaft (12) by two screws (141,142) with two-screw, one side of this cross sliding clock (14) can be provided with a screw (143), and is fixed in an end of cross sliding shaft (15) with screw (144).

Still there are following 2 shortcomings in the use in above rail structure: the one, and it is big that the knot of slide block and slide-bar touches face, and friction acutely causes the slip difficulty of lifting slider and cross sliding clock, makes the tension of paulin frame draw in difficult; The 2nd, gapped between slide block and slide-bar, vehicle slide block inner end surface and slide-bar under steam collides and can make a noise.

The purpose of this utility model is the improvement structure that slide rail in a kind of goods vehicle awning frame will be provided, and the contact surface of its slide block and slide-bar is very little and can reduce friction to make and slide smoothly, and can avoid the noise that bumps.

The purpose of this utility model is achieved in that on the inner end surface of lifting slider and cross sliding clock and with 120 degree three projectioies is set, and lifting slider is contacted with bikini with cross sliding shaft with erect sliding shaft, cross sliding clock, and reduce friction face and crash-avoidance.

The utility model just carries out a very little improvement and can reach and reduce friction and the purpose of crash-avoidance on original slide block structure, it is simple in structure and have a practicality.

Further specify concrete structure of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is the formation scheme drawing of this goods vehicle awning frame.

Fig. 2 is the combination scheme drawing of lifting slider and tilted grating.

Fig. 3 is lifting slider and erect sliding shaft fit scheme drawing.

Fig. 4 is the combination scheme drawing of cross sliding clock and tilted grating.

Fig. 5 is cross sliding clock and cross sliding shaft fit scheme drawing.

Fig. 6 is the fit scheme drawing of lifting slider of the present utility model and erect sliding shaft.

Fig. 7 is the fit scheme drawing of cross sliding clock of the present utility model and cross sliding shaft.

As shown in Figure 6 and Figure 7, divide 120 degree to be provided with three projectioies (211) on the inner end surface of lifting slider (21), it is fashionable with erect sliding shaft (12) cover to be to contact with bikini.On the inner end surface of cross sliding clock (22), also divide 120 degree to be provided with three projectioies (221), it is fashionablely contacted with bikini overlapping with cross sliding shaft (15).This bikini way of contact has knot and touches the little characteristics of face, thereby the friction force between slide block and the slide-bar is reduced, and makes the fit of slide block and slide-bar stablize and can not bump.

Claims

1, the improvement structure of slide rail in a kind of goods vehicle awning frame, it mainly comprises tilted grating, erect sliding shaft, cross sliding shaft, lifting slider and cross sliding clock, wherein this lifting slider is sleeved on the erect sliding shaft, and is arranged with cross sliding clock below erect sliding shaft; The internal end surface that it is characterized in that this lifting slider and cross sliding clock divides 120 degree to be provided with three projectioies, and this lifting slider all contacts with bikini with cross sliding shaft with erect sliding shaft, cross sliding clock.
