Abstract
The utility model discloses a locking device capable of achieving bidirectional synchronous locking. The locking device comprises a telescopic pipe consisting of an inner pipe and an outer pipe, a conical screw mounted in the telescopic pipe and an expansion nut matching with the conical screw in use. The locking device is characterized in that one end of the conical screw is a connector connected with a hole of the inner pipe, the expansion nut is connected with a hole of the outer pipe, the other end of the conical screw is a butt end, the middle of the conical screw is a conical thread, the expansion nut matching with the conical screw is provided with a conical screw hole, and at least one straight slot is formed along the wall of the expansion nut longitudinally at intervals. The connector of the conical screw is connected with the inner pipe of the telescopic pipe, and the inner pipe is rotated; since the conical screw provided with the conical thread rotates in the inner pipe, the expansion nut generates bidirectional expansion on the Y-axis, and then the inner pipe and the outer pipe are fixed by packing; meanwhile, the conical screw also generates increase displacement on the X-axis of the expansion nut, and at the moment, the telescopic pipe can be fixed between two parallel wall surfaces by packing; the locking device is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to locking device, but is specifically related to a kind of locking device of bi-directional synchronization locking.
Background technique
In the prior art, sometimes need two flexible rods that are sleeved on inside and outside pipe fitting are together carried out axially and radially Telescopic Fixed, just the end that two pipe fittings are socket-connected fixes and does not produce radially (moving growth outward) rotation, an other end of two pipe fittings is resisted against respectively on two sidewalls, existing Telescopic Fixed mode is as follows: spring eccentric expansion eccentric expansion adds spring structure, there is following defective in said structure: the oxidation of getting rusty of chip architecture of the spring body, the part complexity, need the gravity squeeze operation, structure is too heavy.
Summary of the invention
The purpose of this utility model is, at the above-mentioned defective of prior art, provides a kind of simple in structure, but the locking device of easy to operate bi-directional synchronization locking.
But construct a kind of locking device of bi-directional synchronization locking, but the locking device that comprises a kind of bi-directional synchronization locking, comprise the telescopic pipe of being formed by interior pipe and outer tube, be installed in the conical screw in the described telescopic pipe, the expanding nut that is used with described conical screw, one end of described conical screw is one and is used for the connecting head be connected with inner orifice, described expanding nut is connected with described outer pore, the other end of described conical screw is a butt end, the stage casing of described conical screw is a taper thread, the described expanding nut that is mated has conical bolt hole, has at least one groove along the longitudinal separation of described expanding nut wall.
But in the locking device of above-mentioned bi-directional synchronization locking, the right side of described expanding nut is the inclined-plane, and the face corresponding with described nut inclined-plane at described conical screw is provided with a screens projection.
But in the locking device of above-mentioned bi-directional synchronization locking, have a groove in the longitudinal separation of described expanding nut.
But in the locking device of above-mentioned bi-directional synchronization locking, be wear resistant plastic or metal construction at described expanding nut.
But in the locking device of above-mentioned bi-directional synchronization locking, the face corresponding with described nut inclined-plane at described conical screw is provided with a screens projection.
The utlity model has following advantage: the connecting head of conical screw is connected with the interior pipe of flexible rod, expanding nut can be sought connections with in the flexible rod outer tube wall, interior pipe inner telescoping tube outside moves the total length of adjusting inner and outer pipes in order to flexible, pipe in the operation rotation, seek connections with the expanding nut in outer tube wall this moment, because the conical screw that conical screw is housed rotates at interior pipe, generation is to the expansion of Y direction, and then in packing fixed, outer tube, simultaneously because of above-mentioned action, the interior pipe that conical screw is housed rotates the movement that expanding nut has also been produced X-axis direction, if load onto on-slip and rubber-like cushion at two ends of telescopic pipe, displacement produces the cushion at packing telescopic pipe two ends, and this moment, flexible rod can be fixed between the two parallel metopes.The utility model is simple in structure, and is easy to operate.

Embodiment
With reference to Fig. 1-shown in Figure 6, but design a kind of locking device of bi-directional synchronization locking, be provided with the telescopic pipe of being formed by interior pipe 4 and outer tube 3, be installed in the conical screw 1 in the described telescopic pipe, the expanding nut 2 that is used with described conical screw 1, one end of described conical screw 1 is one and is used for the connecting head 101 be connected with interior pipe 4 holes, described expanding nut 2 is connected with the endoporus of described outer tube 3, the other end of described conical screw 1 is a butt end, the stage casing of described conical screw 1 is a taper thread, the described expanding nut that is mated 2 has conical bolt hole, has at least one groove 201 along the longitudinal separation of described expanding nut 2 walls.
With reference to Fig. 4-shown in Figure 6, but in the locking device of above-mentioned bi-directional synchronization locking, the right side of described expanding nut 2 is inclined-planes 202, corresponding, 202 corresponding faces are provided with a screens projection 103 on the inclined-plane of described conical screw 1 and described expanding nut 2, when needs unclamp flexible rod, the inclined-plane of expanding nut 2 may be stuck in protruding 103 places, conical screw 1 can rotate synchronously with described expanding nut 2, can be not improper because overworking, when continuous counterrotating, make that conical screw 1 is stuck mutually with described expanding nut 2, lose lock function fixedly the time thereby be directed in needs elongation packing.
But in the locking device of above-mentioned bi-directional synchronization locking, described expanding nut vertically have at least one an expansion groove 201, for reaching good expansion effect, can also have many obstructed expansion slots in the longitudinal separation of expanding nut.
But in the locking device of above-mentioned bi-directional synchronization locking, be wear resistant plastic or metal construction at described expanding nut 2.
The connecting head 101 of conical screw 1 is connected with the interior pipe of flexible rod, expanding nut 2 can be sought connections with in the flexible rod outer tube wall, interior pipe inner telescoping tube outside moves the total length of adjusting inner and outer pipes in order to flexible, pipe in the operation rotation, seek connections with the expanding nut 2 in outer tube wall this moment, because the conical screw 103 that conical screw is housed rotates at interior pipe, generation is to the expansion of Y direction, and then in packing fixed, outer tube, simultaneously, because of above-mentioned action, the interior pipe that conical screw is housed rotates the movement that expanding nut has also been produced X-axis direction, if load onto on-slip and rubber-like cushion at two ends of telescopic pipe, displacement produces the cushion at packing telescopic pipe two ends, and this moment, flexible rod can be fixed between the two parallel metopes.
