Abstract
The utility model relates to an expansion bolt, comprising a screw rod, nuts, a movable fastening rod and a spring piece. The utility model is characterized in that one end of the screw rod can be in the bending shape, the anchoring position of the screw rod is provided with a concave cavity, the inner side of the concave cavity is provided with the movable fastening rod, and the spring piece is connected and positioned between the concave cavity and the movable fastening rod. The expansion bolt has the advantages of simple structure, convenient and rapid performance, and time-saving and labor-saving arrangement and construction, and can be anchored automatically.
Description
Technical field:
The utility model belongs to bolt, especially a kind of novel EXPANSION ANCHOR BOLTS.
Background technique:
Present commercially available EXPANSION ANCHOR BOLTS, its installment work is loaded down with trivial details, need be with instrument fastening nut multi-turns such as spanner or pliers, could be good the EXPANSION ANCHOR BOLTS anchoring, installation rate is slow, and working dynamics is big.
Summary of the invention:
The purpose of this utility model is to provide a kind of novel EXPANSION ANCHOR BOLTS quick and easy for installation, time saving and energy saving, anchoring automatically.
The technical solution of the utility model is as follows:
1, a kind of novel EXPANSION ANCHOR BOLTS comprises by screw rod, nut, movable kelly, spring sheet, it is characterized in that, described screw rod one end is the elbow shape, screw rod anchoring position is provided with cavity, and device has movable kelly in the cavity, has spring sheet to be connected the location between cavity and the movable kelly.
2, as technological scheme 1 described novel EXPANSION ANCHOR BOLTS, wherein, the open-shaped attitude of spring sheet between described movable kelly and the cavity.
The utility model has the advantages that simple in structurely, installation is time saving and energy saving, and is convenient and swift, anchoring automatically.
Description of drawings:
Fig. 1 is an overall structure plan view of the present utility model.
Fig. 2 installs the main sectional view of looking for overall structure of the present utility model.
In Fig. 1, Fig. 2, screw rod anchoring position (1), elbow (2), movable kelly (3), spring sheet (4), cavity (5), screw rod (6), nut (7), basis boring (8).
Embodiment:
Most preferred embodiment of the present utility model is such, with reference to Fig. 1, shown in Figure 2, described screw rod (6) one ends are elbow (2) shape, screw rod anchoring position (1) is provided with cavity (5), cavity (5) is gone up device movable kelly (3), the two ends of spring sheet (4) are connected with cavity (5) and movable kelly (3) respectively, effect by spring sheet (4), prevent that movable kelly (3) from coming off from cavity (5), and make the open-shaped attitude of spring sheet (4) between movable kelly (3) and the cavity (5); One lateral bending head (2) of cavity (5) is held movable kelly (3), prevents to put the left side on the movable kelly (3); Under the acting in conjunction of elbow (2) and spring sheet (4), prevent movable kelly (3) lower end move left and right.
During installation, the EXPANSION ANCHOR BOLTS of corresponding specification is put into basis boring (8), under the effect of spring sheet (4), basis boring (8) is blocked at the upper end of movable kelly (3) and screw rod anchoring position (1), because the distance between movable kelly (3) upper end and the side, screw rod anchoring position (1) is greater than the diameter of basis boring (8), movable kelly (3) cannot enlarge relatively with angle between the screw rod (6), therefore, can make EXPANSION ANCHOR BOLTS realize the purpose of automatic anchoring, as long as EXPANSION ANCHOR BOLTS is put into the position of nut (7) toward boring (8) lining, basis.
Claims (2)
1, a kind of novel EXPANSION ANCHOR BOLTS, comprise screw rod, nut, movable kelly, spring sheet, it is characterized in that, described screw rod (6) one ends are elbow (2) shape, screw rod anchoring position (1) is provided with cavity (5), device has movable kelly (3) in the cavity (5), has spring sheet (4) to be connected the location between cavity (5) and the movable kelly (3).
2, novel EXPANSION ANCHOR BOLTS according to claim 1 is characterized in that, the open-shaped attitude of spring sheet (4) between described movable kelly (3) and the cavity (5).
