DETAILED DESCRIPTION

[0025] The following is a detailed description of a thermoplastic polyolefin vapor barrier provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative methods to implement them; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0026] like Figure 1 - Figure 5 As shown, the embodiment of the utility model provides a thermoplastic polyolefin vapor barrier film, including a frame 1, which is a U-shaped rod structure as a whole, based on the use direction (refer to Figure 1) That is, the closed end of the U-shaped structure faces upward and the open end faces downward. Support rods 2 are provided at the bottom of the lower side of the rod bodies on both sides of the frame 1. The support rods 2 and the side rod parts of the frame 1 are cross-distributed in a herringbone shape. The end walls of the frame 1 and the support rods 2 at the bottom are provided with rollers 3; the mounting seat 4 includes a connecting block 41 and an ear plate 42 fixedly connected to the connecting block 41. The connecting block 41 is fixedly connected to the middle section of the rod bodies on both sides of the frame 1 by screws. The ear plate 42 is located below the connecting block 41, and a connecting hole 43 is opened on the ear plate 42; the mounting shaft 5 is slidably connected with the connecting hole 43, and the mounting shaft 5 is rollingly connected with a vapor barrier membrane 7 on its shaft body; the limiting member 6 is slidably connected with the side rod bodies on both sides of the frame 1, and is arranged parallel to the mounting shaft 5. The limiting member 6 includes a limiting rod 62, and the limiting rod 62 is arranged to be in close contact with the outer side of the vapor barrier membrane 7 when the vapor barrier membrane is laid.

[0027] The vapor barrier film 7 is installed by setting up a frame 1. During use, the frame 1 is pushed or pulled by holding the top of the frame 1, and the frame 1 is driven to drive the vapor barrier film 7 to make horizontal linear motion on the ground under the support of the roller 3, and unwind it at the same time, thereby completing the laying of the vapor barrier film 7. With the auxiliary support of the frame 1, the work is time-saving and labor-saving, and the laid vapor barrier film is of good quality and easy to promote. At the same time, the friction of the limit rod 62 on the vapor barrier film 7 increases the rotational resistance of the vapor barrier film 7 when unwinding, thereby avoiding the problem that the vapor barrier film 7 is unrolled too long due to inertia due to laying too quickly, resulting in stacking and the need to rewind.

[0028] like Figure 1 As shown, there are four rollers 3, and the bottom end of each roller 3 is distributed in a rectangular shape on the same horizontal plane. The roller 3 adopts a directional pulley, and the installation direction of the four rollers 3 is the same, and the rotation center axis of the roller 3 is parallel to the installation axis 5.

[0029] Through this arrangement, during the movement of the frame 1, the directional arrangement of the plurality of rollers 3 assists the frame 1 in performing linear motion.

[0030] like Figure 4 As shown, there are two mounting seats 4, the radial cross section of the connecting block 41 is U-shaped, and fits with the rod bodies on both sides of the frame 1, and a mounting hole is provided in the middle section of the side rod body of the frame 1, and the connecting block 41 is fixedly connected to the side rod body of the frame 1 by bolts.

[0031] like Figure 2 As shown, the installation shaft 5 includes a round shaft 51, which passes through the connecting holes 43 opened on the two ear plates 42 in sequence and is threadedly connected to the limiting block 52; the vapor isolation membrane 7 is in a rolled-up structure, and a sleeve for easy installation is provided at the center position. The vapor isolation membrane 7 is rotatably connected with the round shaft 51 through the center sleeve, and the vapor isolation membrane 7 is located between the two side rods of the frame 1.

[0032] This arrangement makes it easy to replace and install the vapor barrier membrane 7 , and after installation, the vapor barrier membrane 7 is located at the lower side of the side rod body of the frame 1 , thereby lowering its overall center of gravity and further reducing the convenience of controlling the frame 1 .

[0033] like Figure 3 and Figure 5 As shown, a slide groove 8 is provided on the side wall of the rod body on both sides of the frame 1, and the radial cross-section of the slide groove 8 is T-shaped; the limiting member 6 includes a limiting rod 62, and a slider 61 fixedly connected to the two ends of the limiting rod 62 by a thin rod, and the slider 61 is slidably connected with the slide groove 8.

[0034] By providing the slide grooves 8 on the opposite sides of the frame 1 to slide with the slider 61 , the limiting rod 62 can slide linearly when moving.

[0035] like Figure 2 As shown, a spring 9 is provided inside the slide groove 8, one end of the spring 9 is in close contact with the slider 61, and the other end of the spring 9 is in close contact with an end wall of the slide groove 8 away from the mounting shaft 5.

[0036] The spring 9 provides a pressing force for the limiting rod 62 to apply to the vapor isolation membrane 7, thereby improving the rotation limiting effect of the vapor isolation membrane 7.

[0037] The utility model provides a technical solution. Before the vapor barrier film is laid, the finished vapor barrier film 7 is mostly in a roll shape (hereinafter referred to as the vapor barrier film 7, referred to as the vapor barrier film roll) and the vapor barrier film 7 is placed in the middle position of the frame 1 and the limit rod 62 is pressed against the elastic force of the spring 9 so that the central circular hole of the vapor barrier film 7 and the connecting hole 43 on the ear plate 42 are on the same axis. Subsequently, the circular shaft 51 is passed from one end of the ear plate 42 through the connecting hole 43 on the ear plate 42, and successively passes through the central through hole of the vapor barrier film 7 and the connecting hole 43 on the other ear plate 42, and is finally threadedly connected with the limit block 52. At this time, the vapor barrier film 7 is rotatably connected with the circular shaft 51. When laying, the frame 1 is pushed or pulled by holding the top of the frame 1, and the frame 1 is driven to drive the vapor barrier film 7 to make horizontal linear motion on the ground under the support of the roller 3, and the film is unwound at the same time, thereby completing the laying of the vapor barrier film 7.
