Abstract
The utility model provides a novel expansion bolts pulls out and connects ware, belongs to the bolt equipment technical field that chooses, and the technical problem that solve is the device that provides the expansion bolts that can choose, the technical scheme who adopts: a novel expansion bolts pulls out and connects ware, connects the pole, pulls out the nipple including pulling out, first landing leg and second landing leg, pull out and connect the outside cover of pole to be equipped with to pull out the nipple, first landing leg and second landing leg symmetry set up is pulling out the nipple both sides, pull out and connect the pole bottom for pulling out the joint to pull out the joint and for the external screw thread hollow tube, be used for with the bloated pipe thread connection of division female, pull out and connect peak of the staff portion to be the handle, the utility model discloses be applied to the expansion bolts that chooses.
Description
Technical field
A kind of upset bolt pulls out and connects device, belongs to bolt and to choose equipment technical field.
Background technology
The style of expansion bolt has varied, and generally conventional is expansible anchor of metal, is also Tube type expanded bolt.In the GB/T22795 of national standard, be referred to as sleeve pipe strengthen expansion bolt, the reinforced expansion bolt of sleeve pipe is made up of 4 dozens of parts, is dormant bolt respectively, expand tube, plain washer and spring pad add hex nut composition.Serve object fixation in daily life.But fixture reach certain time limit discarded after, expansion bolt is also discarded in body of wall, causes the wasting of resources.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of device of expansion bolt of can choosing.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts: a kind of upset bolt pulls out and connects device, comprise pull out extension bar, pull out female connector, the first supporting leg and the second supporting leg, described extension bar outer cover of pulling out is equipped with and pulls out female connector, described first supporting leg and the second supporting leg are symmetricly set on and pull out female connector both sides, described in pull out for pulling out joint bottom extension bar, and to pull out joint be external screw thread hollow pipe, for being threaded with opening female expand tube, described in pull out extension bar top be handle.
Describedly pull out joint and to pull out extension bar be detachable installation.
Describedly pull out extension bar and to pull out female connector be matched in clearance.
Described first supporting leg and the second supporting leg are fixedly connected on and pull out female connector both sides.
Described first supporting leg and the second supporting leg are movably connected in and pull out female connector both sides.
Compared to the prior art the utility model has following beneficial effect.
One, by opening the externally threaded tube expanding joint pulling out joint and open internal thread, contact as fulcrum with the second supporting leg with wall by the first supporting leg again, handle just can be caught to be taken out from body of wall by expansion bolt easily, thus efficiently again can utilize expansion bolt, stop the wasting of resources.
Two, by pulling out joint and pulling out extension bar and be designed to removably connect, pull out joint can as required for different size expansion bolt thus adopt the hollow male-pipe of different size, application is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is handle, and 2 for pulling out female connector, and 3 is the first supporting leg, and 4 is the second supporting leg, and 5 for pulling out extension bar, and 6 for pulling out joint.
Detailed description of the invention
Embodiment one
As shown in Figure 1, a kind of upset bolt pulls out and connects device, comprise and pull out extension bar 5, pull out female connector 2, first supporting leg 3 and the second supporting leg 4, described extension bar 5 outer cover of pulling out is equipped with and pulls out female connector 2, described first supporting leg 3 and the second supporting leg 4 are symmetricly set on and pull out female connector 2 both sides, described in pull out for pulling out joint 6 bottom extension bar 5, and pull out joint 6 for external screw thread hollow pipe, for being threaded with opening female expand tube, described in pull out extension bar 5 top be handle 1.
Describedly pull out joint 6 and pull out extension bar 5 for detachable installation.
Describedly pull out extension bar 5 and pull out female connector 2 for matched in clearance.
Described first supporting leg 3 and the second supporting leg 4 are fixedly connected on and pull out female connector 2 both sides.
Embodiment two
As shown in Figure 1, a kind of upset bolt pulls out and connects device, comprise and pull out extension bar 5, pull out female connector 2, first supporting leg 3 and the second supporting leg 4, described extension bar 5 outer cover of pulling out is equipped with and pulls out female connector 2, described first supporting leg 3 and the second supporting leg 4 are symmetricly set on and pull out female connector 2 both sides, described in pull out for pulling out joint 6 bottom extension bar 5, and pull out joint 6 for external screw thread hollow pipe, for being threaded with opening female expand tube, described in pull out extension bar 5 top be handle 1.
Describedly pull out joint 6 and pull out extension bar 5 for detachable installation.
Describedly pull out extension bar 5 and pull out female connector 2 for matched in clearance.
Described first supporting leg 3 and the second supporting leg 4 are movably connected in and pull out female connector 2 both sides.
The utility model to pull out the expansion bolt that connects substantially identical with expansion bolt structure of the prior art, all add a hex nut by dormant bolt, expand tube, plain washer and spring pad to form, both unique difference be exactly the utility model pull out the expansion bolt connect expand tube have internal thread, be convenient to like this match with the externally threaded joint 6 that pulls out.
Above-described embodiment is unrestricted to explanation of the present utility model; not departing from the distortion done under the utility model principle prerequisite also within protection domain of the present utility model, such as, from three supporting legs, three more stable supporting legs are become to the quantity of the first supporting leg 3 and the second supporting leg 4.
