Abstract
The utility model discloses a novel anchor rod, which is composed of an anchor head (1), a rod body (2), a tray (3), and a nut (4). The novel anchor rod is characterized in that screw threads are arranged all over the rod body (2), and the screw threads are tube screw threads. The nut (4) is matched with the screw threads on the rod body, and the internal screw threads are also tube screw threads. In addition, the screw threads on the nut and the rod body can realize self lock. The novel anchor rod has the advantage of novel design. The problem that the anchor rod is not screwed tightly can be avoided effectively, and stress concentration of the screw threads of the anchor rod can also be reduced. The screw threads are prevented from thread shedding.
Description
The utility model relates to a kind of anchor pole, particularly a kind of novel anchor rod.
Bolt support is widely used aspect supporting roadway surrounding rock, it is simple in structure, cost is low, easy to use, supporting effect is good, but also found its some defectives in the use, the one, because anchor bar body tailing screw flight length is shorter, the degree of depth of anchor pole insertion sometimes is suitable inadequately, particularly the anchor tail exposes when too many, nut does not also compress pallet, has arrived the screw thread end, causes pallet loosening, do not have due support action, tooth form owing to screw thread on the present anchor pole mostly is triangle on the other hand, and this tooth form is easy to produce stress and concentrates, thereby causes running.
The purpose of this utility model just provides a kind of modern design, and it is tight effectively to avoid anchor pole to twist, and can reduce the stress of screw thread again and concentrate, and prevents the novel anchor rod of screw thread running.
The utility model adopts technical scheme as described below for achieving the above object: novel anchor rod also is made up of anchor head, the body of rod, pallet and nut, its difference is that entire body all has screw thread on the body of rod, and the tooth form of this screw thread is the gas thread tooth form, also be the gas thread tooth form with the tooth form of internal thread on the nut that body of rod screw thread matches, and the screw thread on the nut and the body of rod can be realized self-locking.
After having adopted said structure and since the length of screw thread with the equal in length of anchor rod body, can not occur again that nut is screwed to the screw thread end and the phenomenon that do not press tightly pallet, adopt gas thread in addition after, the stress that has significantly reduced screw thread is concentrated, thereby prevents the screw thread running.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the body of rod and nut form of thread schematic diagram under engagement.
With reference to Fig. 1, Fig. 2.Novel anchor rod is made up of anchor head 1, the body of rod 2, pallet 3 and nut 4, entire body all has screw thread on the body of rod 2, and this screw thread is a gas thread, with the tooth form of internal thread on the supporting nut 4 of body of rod threaded engagement also be the gas thread tooth form, and the screw thread on the nut and the body of rod can be realized self-locking.
Claims (2)
1, a kind of novel anchor rod, it is made up of anchor head (1), the body of rod (2), pallet (3) and nut (4), it is characterized in that: the body of rod (2) is gone up entire body all screw thread.
2, novel anchor rod according to claim 1 is characterized in that: the screw thread on the body of rod (2) is a gas thread.
