Abstract
The invention discloses a kind of lower margin and fix pricker device, comprise fixing drill steel and supporting pull up bar two parts, described fixing drill steel by the body of rod, can turn nut and swing arm form, the body of rod is cylinder, and be provided with round platform on its top, tail end is provided with cone, lower horizontal near round platform is provided with two symmetrical hollow cylinder swing arms, being provided with near the below of swing arm can turn nut, is threaded connection, turn nut horizontal direction within one week, can evenly having one group of groove between itself and the body of rod; Described supporting one end pulling up bar is the part with swing arm grafting, the other end be with can the part of groove grafting on turn nut.The present invention does not need to lever up instrument, and avoid because External Force Acting causes the damage on drill steel top, structure is simple, cost is low, easy to use, fixed.
Description
Technical field
The present invention relates to Machine Design and manufacture field, particularly a kind of for ground support fastening devices.
Background technology
The conventional ground support fixed equipments such as tent, prefabricated house, booth, flagpole, guardrail, hedge are generally the taper single pole shape with rivet or annulus, in fixation procedure, need to utilize iron hammer to knock in ground play fixing effect, and when dismantling this equipment, need utilization to lever up instrument and utilize lever principle to be prized as the one end such as nail puller, crowfoot or iron pipe are against rivet lower end.Not only carrying implement is many, and very easily damages rivet.
Summary of the invention
the technical problem solved:the invention provides a kind of lower margin and fix pricker device, can when not needing to lever up instrument fixed bottom boundary support, avoid because External Force Acting causes the damage on drill steel top.
technical scheme:a kind of lower margin fixes pricker device, comprise fixing drill steel and supporting pull up bar two parts, described fixing drill steel by the body of rod, can turn nut and swing arm form, the body of rod is cylinder, and be provided with round platform on its top, tail end is provided with cone, lower horizontal near round platform is provided with two symmetrical hollow cylinder swing arms, being provided with near the below of swing arm can turn nut, is threaded connection, turn nut horizontal direction within one week, can evenly having one group of groove between itself and the body of rod; Described supporting one end pulling up bar is the part with swing arm grafting, the other end be with can the part of groove grafting on turn nut.
The α angle of body of rod top round platform described above is 60 °, and the β angle of tail end cone is 40 °.
Described above can the groove on turn nut be 2 ~ 6.
Described above can be provided with spiral pattern in turn nut surface.
It is 45 steel that surface is coated with white zine that lower margin described above fixes pricker device.
beneficial effect:compared with prior art, the present invention can reach following beneficial effect:
1. can fixing drill steel be securely fixed on ground after turn nut, prevent external force from causing loosening of fixing drill steel;
2. swing arm be arranged so that when not needing in addition to lever up instrument, fixing drill steel can being extracted in ground, the External Force Acting because levering up can being avoided to cause the damage on drill steel top;
3. the present invention adopts 45 steel, and make machining convenient, structure easily realizes;
4. support device of the present invention is few, and cost is low.

Detailed description of the invention
embodiment 1
Shown in composition graphs 1, the present invention includes fixing drill steel 1 and supporting pull up bar 2.The body of rod 3 of fixing drill steel 1 is cylinder, to be α angle be on its top round platform of 60 °, is two symmetrical hollow cylinder swing arms 5 below round platform, tail end to be β angle the be cone of 40 °.Can be positioned at below swing arm 5 by turn nut 4, and be threaded connection between the body of rod 3, spiral pattern is carved with on its surface, not used time desirable lower preservation.The horizontal direction of turn nut 4 within one week, can evenly have 4 grooves, be used for coordinating the supporting tail end turn pulling up bar 2 can turn nut 4.The supporting top pulling up bar 2 is used for being enclosed within the outside of swing arm 5 by its turn, and the port of swing arm 5 is equipped with corresponding locking member.The supporting bar 2 that pulls up has 2 ~ 4.
Regularly during foot support, first can screw on the body of rod 3 by turn nut 4, and and leave a fixed gap between swing arm 5, more fixing drill steel 1 is penetrated support to be fixed annulus hinge plate hole in together press on the ground, knock the projection position on fixing drill steel 1 top with iron hammer.
As shown in Figure 1, utilize the supporting downward turn of the projecting tails pulling up bar 2 can recess hole on turn nut 4 until be screwed into the tightest.
During dismounting, as shown in Figure 1, first unscrewing with the supporting afterbody pulling up bar 2 can turn nut 4, then is enclosed within swing arm 5 by the supporting upper horizontal pulling up bar 2, as shown in Figure 2, is unscrewed, and takes out fixing drill steel 1 from ground.
Described in the present invention, concrete case study on implementation is only better case study on implementation of the present invention, is not used for limiting practical range of the present invention.Namely all equivalences done according to the content of the present patent application the scope of the claims change and modify, all should as technology category of the present invention.
