Detailed Description

The invention will be further described with reference to the following specific embodiments and the accompanying drawings.

Example one

As shown in fig. 3 to 4, the anti-theft lattice rod comprises a rod body 1, wherein the rod body 1 is a hollow tube made of metal, preferably a stainless steel rectangular hollow tube. As shown in fig. 1, in the prior art, the pulley 2 is installed by cutting one installation opening at both ends of a rectangular hollow tube for installing the pulley 2, and generally, the pulley 2 is installed at the bottom and may or may not be installed at the upper part. Because the width of the rectangular hollow tube is limited, generally 18mm, the size of the upward and downward sliding of the section bars of some manufacturers on the market cannot be met, and naturally, the window made of the section bars cannot be matched with the window. Generally, the lower slide 3 is provided with a slide rail which can be matched with the pulley 2, and the upper slide 4 is mostly of a groove-shaped structure, the groove-shaped structure is not matched with the rectangular hollow pipe in size, the gap is large, and the swing is easy to occur. Therefore, the mounting structure of the original rod piece is improved, and the upper end part and the lower end part of the rod piece body 1 are detachably connected with the pulley joints 5. The pulley joint 5 comprises a pulley mounting part, the pulley mounting part comprises a bottom panel 6 and side panels 7 connected to the left end and the right end of the bottom panel 6, and the bottom of the bottom panel 6 is connected with an inserting part 8. The insertion part 8 is inserted into the end of the rod body 1 to replace the original installation structure of the end of the rod, so that the width of the end of the rod is increased. A wheel shaft 9 is connected between the side panels 7, and at least one pulley 2 is arranged on the wheel shaft 9. E.g. one pulley 3, on both the top and bottom, as shown in fig. 5. The lower slide 3 is generally provided with one pulley 2 and the upper slide is provided with two pulleys 2 as an example, as shown in fig. 6. Can set up gasket 10 between the pulley 2, adjust the distance between the pulley 2 through gasket 10, through its regulation, make its pulley 2 match with the width of groove-shaped structure, by pulley 2 cooperation groove-shaped structure slip, avoided current problem that exists. The gasket 10 is provided with a bayonet 11, and the gasket 10 is directly buckled on the wheel shaft 9 through the bayonet 11 so as to be capable of freely rotating along with the pulley 2. Of course, the washer 10 may be provided without the bayonet 11, and only the middle axle hole is needed, and the axle 9 is inserted into the axle hole when being installed. The spacer 10 is preferably made of elastic plastic, and the spacer 10 can be provided with spacers of various thicknesses, so that the mounting adjustment is more facilitated, and the distance between the pulleys 2 is controlled. The pulley joint 5 can be an integral joint made of metal materials or an integral rubber piece made of rubber.

The utility model has simple structure, reasonable design and strong practicability, and can realize the adjustment of the distance between the pulleys 2 by arranging the gasket 10 between the pulleys 2 so as to realize the matching butt joint of the up-down sliding 3 and the pulleys 2; meanwhile, the installation is convenient, the cost is reduced, and the corresponding problems in the prior art are effectively solved.

Example two

The pulley joint 5 as in the first embodiment is in the form of a rubber member made of rubber, because its strength is not so good. Transverse plates 101 can be arranged on the left side and the right side of the end part of the rod body 1, a vertical plate 102 perpendicular to the transverse plates 101 is arranged at the free end of the transverse plates 101 upwards, and the transverse plates 101 and the vertical plate 102 form a bearing space 501 matched with the outside of the pulley joint 5, as shown in fig. 2. When the insertion part 8 of the pulley joint 5 is inserted into the end of the rod body 1, the bottom panel 6 of the pulley joint 5 is attached to the horizontal plate 101 of the rod body 1, and the side panel 7 of the pulley joint 5 is attached to the vertical plate 102 of the rod body 1, as shown in fig. 7. The bearing space 501 formed by the transverse plate 101 and the vertical plate 102 can be directly formed by stamping and expanding the rod body 1, and the corresponding glue pieces arranged on the bearing space can meet the requirements of up-and-down sliding sizes of different aluminum products.

EXAMPLE III

The difference between this embodiment and the above embodiments is that, as shown in fig. 8, the side of the rod member body 1 is provided with the adjusting screw 20, and the adjusting screw can be arranged on one side alone, or on both sides correspondingly, and the two sides are symmetrically arranged to better satisfy the strength. The adjusting screw 20 is used for adjusting the plugging depth of the plugging portion 8. The principle is that a threaded hole is formed in the side face of the rod body 1, and the adjusting screw 20 is in threaded fit with the threaded hole, so that the inserting portion 8 is loosened or pressed. Loosening adjusting screw 20, grafting degree of depth's regulation just can be carried out to grafting portion 8, that is to the regulation of member overall length promptly, and when member overall length is suitable the back, the grafting degree of depth of grafting portion 8 is confirmed, then compresses tightly grafting portion 8 through screwing up adjusting screw 20, realizes its fixed, and is very convenient and fast.

Example four

The difference between this embodiment and the above embodiments is that the pulley joint 5 located at the upper part of the rod member body 1 may not be provided with the pulley 2, but only the pulley joint 5 located at the bottom of the rod member body 1 is provided with the pulley 2, the pulley joint 5 at the upper part is matched with the groove-shaped structure, and the pulley joint 5 without the pulley 2 is limited by the side panels 7 at both sides of the pulley joint 5 and can slide along with the friction, as shown in fig. 11.

Meanwhile, in order to further ensure sufficient strength and difficult fracture of the stamping, as shown in fig. 12, the vertical plate 102 of the bar body 1 is provided with an inward folded edge 30, the transverse plate 101 is also provided with an inward folded edge 30, and the folded edge 30 of the transverse plate 101 is not shown in the figure. The height of the flange 30 projecting is equivalent to the thickness of the tube wall of the rod body 1. Therefore, the strength can be enhanced, and a better stabilizing effect can be achieved on the rubber part. If the flange 30 is not provided, only the metal sheet of the wall thickness is easily deformed and does not have much strength. Of course, in order to make the rod body less prone to fracture during the stamping process, the end portion of the rod body 1 may be stamped into the structural form shown in fig. 13, that is, the angle is not limited to 90 degrees, and similarly, the rubber member needs to be provided with a shape matched with the rubber member.

The utility model has simple structure, reasonable design and strong practicability, and can realize the adjustment of the rod piece in the length direction through the adjusting screw 20; the distance between the pulleys 2 can be adjusted by arranging the gaskets 10 between the pulleys 2, so that the up-down sliding and the pulley 2 are in matched butt joint; meanwhile, the installation is convenient, the cost is reduced, and the corresponding problems in the prior art are solved. The installation-mated state thereof is shown in fig. 9 and 10.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
