The lifting type fixing and locking device is characterized in that the lower end of the fixed stand column is provided with a sub cup conical thread, a flat wrench clamping opening is arranged between the sub cup conical thread and the external thread, a sub cup cone matched with the main cup cone is additionally arranged, the sub cup cone is connected to the sub cup conical thread at the lower end of the fixed stand column through an internal thread, and the fixed stand column is vertically fixed to the internal thread of the main cup cone through the sub cup conical thread.
The lifting type fixing and locking device is characterized in that the external thread of the fixing stand column is matched with the internal thread of the adjusting nut, the adjusting nut is rotated clockwise, the adjusting nut descends along the external thread of the fixing stand column, the adjusting nut is rotated anticlockwise, and the adjusting nut ascends and descends along the external thread of the fixing stand column.
The beneficial effect of this application lies in: 1) The device fixes the structural part on the support upright post through the clamping nut and the clamping bolt, and adjusts the height of the clamping bolt through the adjusting nut on the support upright post, thereby realizing the adjustment of the fixed height and the fixed length of the structural part. 2) The female cup cone of the device can be embedded underground, the whole set of fixed locking device is made into a ground rooting device, and the fixed processing equipment is fixed on the ground by the plurality of lifting fixed locking devices and is not directly connected with a processed object, so that the processing error caused by factors such as equipment dead weight and vibration is reduced, and the processing quality is improved. 3) The butt joint mode of the primary cup cone and the secondary cup cone of the device is rapid and accurate in positioning, and convenient to detach and install. 4) The specifications and sizes of all parts in the device can be adjusted according to actual fixed locking objects, and the using number of the device can be changed according to the characteristics of the fixed locking objects, namely, the small-sized structure can achieve the fixed locking function only by one set of the device, and a large-sized structure can simultaneously adopt a plurality of devices for fixing, so the device has strong applicability and wide application prospect.
The present application is described in further detail below with reference to the accompanying drawings of embodiments.
Drawings
Fig. 1 is a schematic structural diagram of a lifting type fixing and locking device.
Fig. 2 is a schematic view of the connection relationship of the lifting type fixing and locking device.
Fig. 3 is a schematic structural view of a fixed upright post.
The numbering in the figures illustrates: the structure comprises a structural member 1, a fixed upright post 2, an adjusting nut 3, a clamping bolt 4, a clamping nut 5, a secondary cup cone 6, a primary cup cone 7, a wrench clamping opening 8 and a secondary cup cone screw thread 9.
Detailed Description
Referring to the attached drawings, the lifting type fixing and locking device comprises a fixing upright post 2, a clamping nut 5, a clamping bolt 6 and an adjusting nut 3, wherein the fixing upright post 2 is of a screw rod structure, and the adjusting nut 3 is connected to the external thread on the middle part of the fixing upright post 2 through internal threads.
A wrench clamping opening is formed, so that the cup cone screw rod descends until an external thread at the lower part of the cup cone screw rod is connected with an internal thread of the female cup cone and is screwed, and at the moment, the adjusting bolt and the adjusting nut are still in a locking state;
in implementation, the lower end of the fixed upright post 2 is provided with a sub-cup cone thread 9, a flat wrench clamping opening 8 is arranged between the sub-cup cone thread 9 and the external thread, a sub-cup cone 6 matched with the mother cup cone 7 is arranged, and the sub-cup cone 6 is connected to the sub-cup cone thread 9 at the lower end of the fixed upright post 2 through an internal thread.
In implementation, the female cup cone is usually embedded underground, the sub cup cone at the lower end of the fixed upright post is butted on a central hole of the female cup cone, and the fixed upright post 2 is rotated by a tool through a wrench clamping opening 8 at the lower end of the fixed upright post, so that the fixed upright post 2 is vertically fixed on an internal thread of the female cup cone 7 through a screw thread 9 of the sub cup cone.
The internal thread of the clamping nut 5 is matched with the external thread on the clamping bolt 4, the clamping bolt 4 is a hollow bolt with a central through hole, the clamping bolt 4 is sleeved on the upper part of the fixed upright post 2 through the central through hole, one end of a bolt rod of the clamping bolt 4 faces upwards, and a bolt head of the clamping bolt 4 is positioned on the upper surface of the adjusting nut 3.
