Abstract
The invention relates to a hardware part, in particular to a double-ended left-right threaded drawbar with a long telescopic distance. The double-ended left-right threaded drawbar comprises a middle connector and connecting heads mounted at the two ends of the connector, wherein the connector is a structure with nuts at two ends and a square frame in middle; the nuts at the two ends are separately a left-handed left nut and a right-handed right nut; each connecting head comprises a screw and a pendant; each screw is a structure matched with the corresponding nut; each pendant is arranged at the outer end of the corresponding screw; each pendant is a bent hook or a connecting ring; the inner part of the screw, which is a first screw, of one connecting rod is of a hollow core structure; the outer surface of the screw, which is a second screw, of the other connecting rod can be inserted into the hollow core structure; and the center line of the first screw and the center line of the second screw are on an integrated straight line. The double-ended left-right threaded drawbar with the long telescopic distance has the advantages of being capable of increasing a range within which the two pendants can be moved, and meeting some mounting requirements.
Description
Technical field
The present invention relates to five metals parts, concretely relate to double end left and right thread.
Background technology
Double end left and right thread has the connector of centre and is arranged on the union joint at connector two ends, and described connector is that two ends have nut, there is the structure of square frame centre, and the nut at two ends is the right nut of left-handed left nut and dextrorotation respectively; Union joint includes screw rod and suspension member, screw rod is to cooperate with the structure of nut, and screw rod outer end is suspension member, and described suspension member is crotch or connects ring, the body that is rotatably connected during use can make two suspension members closely close to centre or separate at a distance, to reach tension or to unclamp the effect of connection member; In prior art, the screw rod of two connectors is all solid, and so, it is limited that certain connector has the position that connector moves, it is impossible to meets the requirement that the longer distance of suspension member is flexible, can not meet the requirement of some installations.
Summary of the invention
The purpose of the present invention is aiming at disadvantages mentioned above, it is provided that two moveable scopes of suspension member of a kind of increase, meet the double end left and right thread long telescopic distance of some installation requirements from double end left and right thread.
The technical scheme is that and be achieved in that: long telescopic distance from double end left and right thread, including middle connector and the union joint being arranged on connector two ends, described connector is that two ends have nut, there is the structure of square frame centre, and the nut at two ends is the right nut of left-handed left nut and dextrorotation respectively; Union joint includes screw rod and suspension member, screw rod is to cooperate with the structure of nut, screw rod outer end is suspension member, described suspension member is crotch or connects ring, it is characterized in that: the inside screw of one of them union joint is hollow core structures, this screw rod is the first screw rod, may be inserted in hollow core structures outside the screw rod of another union joint, this screw rod is the second screw rod, and the first screw rod and the second pitch line are on one straight line.
Saying further, the described hollow core structures in the first screw rod has screw thread, the screw thread outside threaded engagement the second screw rod.
The invention has the beneficial effects as follows: such double end left and right thread has the advantage that can increase two moveable scopes of suspension member, meet some installation requirements;The described hollow core structures in the first screw rod has screw thread, the screw thread outside threaded engagement the second screw rod, the advantage also with the bearing strength increasing the present invention.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the present invention.
Wherein: 1, connector 2, union joint 3, screw rod 4, suspension member 5, hollow core structures the 6, first screw rod the 7, second screw rod 8, screw thread.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, long telescopic distance from double end left and right thread, including middle connector 1 and the union joint 2 being arranged on connector two ends, described connector is that two ends have nut, there is the structure of square frame centre, and the nut at two ends is the right nut of left-handed left nut and dextrorotation respectively; Union joint includes screw rod 3 and suspension member 4, screw rod is to cooperate with the structure of nut, screw rod outer end is suspension member, described suspension member is crotch or connects ring, it is characterized in that: the inside screw of one of them union joint is hollow core structures 5, this screw rod is the first screw rod 6, may be inserted in hollow core structures outside the screw rod of another union joint, this screw rod is the second screw rod 7, and the first screw rod and the second pitch line are on one straight line.
So, can also continue to move to the direction that suspension member shrinks time staggered two union joint screw rod ends, add the stroke of union joint, there is advantages of the present invention.
Saying further, the described hollow core structures in the first screw rod has screw thread 8, the screw thread outside threaded engagement the second screw rod, so can also share at the position of this cooperation some suspension members outside pull strength, there is the advantage that ability to bear is higher.
The foregoing is only specific embodiments of the invention, but the architectural feature of the present invention is not limited to this, any those skilled in the art is in the field of the invention, and change or the modification made all are encompassed in the scope of the claims of the present invention.
Claims (2)
1. long telescopic distance from double end left and right thread, including middle connector and the union joint being arranged on connector two ends, described connector is that two ends have nut, there is the structure of square frame centre, and the nut at two ends is the right nut of left-handed left nut and dextrorotation respectively; Union joint includes screw rod and suspension member, screw rod is to cooperate with the structure of nut, screw rod outer end is suspension member, described suspension member is crotch or connects ring, it is characterized in that: the inside screw of one of them union joint is hollow core structures, this screw rod is the first screw rod, may be inserted in hollow core structures outside the screw rod of another union joint, this screw rod is the second screw rod, and the first screw rod and the second pitch line are on one straight line.
2. long telescopic distance according to claim 1 from double end left and right thread, it is characterized in that: the described hollow core structures in the first screw rod has screw thread, the screw thread outside threaded engagement the second screw rod.
