Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 3, for the utility model discloses a combination formula is built with to wearing pull rod in room, including connecting rod 1, connecting hole 11 rather than with the central axis is seted up respectively at the both ends of connecting rod 1, and threaded connection has rather than the solenoid 12 with the central axis in two connecting holes 11 respectively. A locking piece 13 (marked in figure 2) which can lock the screw pipe 12 in a rotating way is arranged in the screw pipe 12, and the screw pipe 12 is sleeved and connected with a screw connecting piece 14 for clamping a concrete template in a threaded way. Wherein, the profile of the 12 threaded tooth of solenoid is right trapezoid, and the right trapezoid inclined plane of two 12 threaded screw of solenoids sets up in opposite directions to bear the ability of axial force when being connected between solenoid 12 and connecting rod 1 for increasing. Wherein, the two ends surrounding the connecting rod 1 are respectively and fixedly connected with an abutting flange 16 used for abutting against the concrete formwork.

When using, the both ends of connecting rod 1 butt respectively in the template that is used for concreting, make the concrete form by the centre gripping between the tip of spiro union piece 14 and connecting rod 1 can, simultaneously because need rotate spiro union piece 14 with concrete form fastening centre gripping, do the rotation locking to screwed pipe 12 through lock piece 13, when reducing to rotate spiro union piece 14 and do the fastening centre gripping to the concrete form, lead to the not hard up possibility of screwed pipe 12 relative connecting rod 1, after the construction is accomplished, only need make the relative screwed pipe 12 of lock piece 13 break away from, then rotate screwed pipe 12 make its relative connecting rod 1 break away from can, it is comparatively convenient to dismantle, in order to optimize the result of use.

Referring to fig. 2 and 3, the inner wall of the solenoid 12 is in a regular hexagon structure, the locking member 13 is in a rod-shaped structure and is adapted to the inner wall of the solenoid 12, the bottom wall of the connecting hole 11 is provided with a locking hole 111 having the same central axis as the connecting hole, the locking hole 111 is adapted to the outer wall of the locking member 13, and the locking member 13 passes through the solenoid 12 and is inserted into the locking hole 111. So that after in 12 threaded connection connecting holes 11 of solenoid, because the outer wall adaptation of locking piece 13 is in the inner wall and the locking hole 111 of solenoid 12, locking piece 13 can be through passing solenoid 12 and insert and locate in locking hole 111 for solenoid 12 relative connecting rod 1 rotates the locking, when dismantling, only needs to extract locking piece 13 can cancel the rotation locking to solenoid 12 simultaneously, uses comparatively convenient light relatively.

The end of the coil 12 far from the locking hole 111 is formed with a rotating portion 122 having an outer wall in a regular hexagonal structure so as to rotate the coil 12.

The end part of the locking piece 13 far away from the locking hole 111 is provided with a limiting piece 15 for sliding and locking the locking piece 13, so that the possibility that the locking piece 13 slides out of the locking hole 111 to cause rotation locking failure of the screw pipe 12 relative to the connecting rod 1 is reduced when the connecting rod is used.

Referring to fig. 2 and 3, one end of the coil 12, which is far away from the locking hole 111, is fixedly connected with a limiting coil 121 which is coaxial with the end, and the outer diameter of the limiting coil 121 is smaller than that of the coil 12; the limiting piece 15 is of a tubular structure with one closed end, the limiting piece 15 is connected to the outer wall of the limiting screw pipe 121 in a threaded mode, and the outer diameter of the limiting piece 15 is smaller than or equal to that of the screw pipe 12. Wherein the limiting member 15 is sleeved on the limiting screw tube 121, and the closed end of the limiting member 15 is rotatably connected to the end of the locking member 13 far away from the locking hole 111.

The screw 14 includes a backing plate 141 and a fastening block 142 externally sleeved on the screw 12, opposite side plates of the two backing plates 141 can be respectively abutted against the concrete formwork, the fastening block 142 is in threaded connection with the outer wall of the screw 12, and the two fastening blocks 142 are respectively located on opposite sides of the two backing plates 141.
