Description
Technical field
The utility model relates to building material technical field, is specifically related to a kind of dry wall opposite-pull screw special.
Background technology
Clear-water concrete claims again ornamental concrete, because it has decorative effect, gains the name.It belongs to one-time cast-forming; do not make any outer decoration; directly adopt the natural surface effect of cast-in-situ concrete as facing; therefore be different from ordinary concrete; its surface color is even, corner angle clearly demarcated, without clashing and breaking and pollution; just on surface, be coated with one deck or two-layer transparent protective agent, seem very natural, serious.Objective demand along with green building, improving constantly of people's environmental consciousness, return Piao and return being rooted in the hearts of the people of genuine natural thought, the demand of China's clear-water concrete engineering is no longer confined to road and bridge, factory building and airport, in industry and civilian construction, also obtained certain application, clear-water concrete need to be used Screw arbor with nut at both-ends in construction and fix template, existing Screw arbor with nut at both-ends is in application, the assembly and disassembly of screw rod are more time-consuming, because afterbody adopts nut and screw cooperation, carry out fastening, when dismantling, nut is easily lost, and when installing, the time is longer, improved the time of installing and dismantling.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of can Fast Installation and do not adopt nut and screw to be fixed to prevent the dry wall opposite-pull screw special that nut is lost.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: a kind of dry wall opposite-pull screw special, comprise the first outer bar, the second outer bar, connecting rod, the first cone and the second cone, the two ends of connecting rod are provided with external screw thread, the internal thread of external screw thread and the first cone and second cone one end spins, the other end of the first cone and the second cone is connected with the second outer bar with the first outer bar respectively, the first described outer bar and the tail end of the second outer bar are respectively provided with one first and rotate fixed structure, the first described rotation fixed structure comprises turning cylinder, the axis of turning cylinder and the first outer bar, the axis of the second outer bar is vertical, on described turning cylinder, being provided with one can be around the foot piece of turning cylinder rotation, on described foot piece, be provided with a positioning bead, at the first outer bar corresponding with it, the second outer bar be provided with locating hole, locating hole coordinates with positioning bead.
Further concrete, the cylinder of described foot piece is provided with a screwed hole, on described screwed hole, one handle is installed.
Further concrete, the afterbody of described foot piece be provided with one with the first outer bar, the second rotation fixed structure that the second outer bar tail structure is identical.
The utlity model has following beneficial effect: it is simple in structure, reasonable in design, easy to use, and good looking appearance is generous, and fixed form is firm, convenience quick for installation, nut is not easy to lose, and its cost is low, more economically, cost-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram that in Fig. 1, A part first is rotated fixed structure.
In figure: 1, connecting rod; 2, the first cone; 3, the second cone; 4, the first outer bar; 5, the second outer bar; 6, foot piece; 7, handle; 8, turning cylinder; 9, locating hole.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is explained in detail.
A kind of dry wall opposite-pull screw special as depicted in figs. 1 and 2, comprise the first outer bar 4, the second outer bar 5, connecting rod 1, the first cone 2 and the second cone 3, the two ends of connecting rod 1 are provided with external screw thread, the internal thread of external screw thread and the first cone 2 and second cone 3 one end spins, the other end of the first cone 2 and the second cone 3 is connected with the second outer bar 5 with the first outer bar 4 respectively, the first described outer bar 4 and the tail end of the second outer bar 5 are respectively provided with one first and rotate fixed structure, the first described rotation fixed structure comprises turning cylinder 8, the axis of turning cylinder 8 and the first outer bar 4, the axis of the second outer bar 5 is vertical, on described turning cylinder 8, being provided with one can be around the foot piece 6 of turning cylinder 8 rotations, on described foot piece 6, be provided with a positioning bead, at the first outer bar 4 corresponding with it, the second outer bar 5 be provided with locating hole 9, locating hole 9 coordinates with positioning bead.
Dismantle for convenience the first outer bar 4 and the second outer bar 5, the cylinder of described foot piece 6 is provided with a screwed hole, one handle 7 is installed on described screwed hole, rectangular by handle 7 and foot piece 6 and the outer bar 5 of the first outer bar 4, second, by handle 7 rotations, dismantle.
Another embodiment, the afterbody of described foot piece 6 is provided with a second rotation fixed structure identical with outer bar 5 tail structures of the first outer bar 4, second, also by rotation, completes dismantlement work.
