Description

Anti-lost manual bolt

Technical Field

The utility model discloses be applied to connection structure's technical field, in particular to prevent losing manual bolt.

Background

With the development of automation equipment, one equipment is gradually popularized for the production of a plurality of models. The screw that fixes when switching between the machine type at present all is the hexagon socket head cap screw commonly used, uses the problem of this kind of screw to need the spanner, and the screw is lost easily. Debugging personnel often waste a significant amount of valuable tuning time because no wrench or screw is lost.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a simple structure, convenient to use's prevent losing hand bolt.

The utility model adopts the technical proposal that: the utility model discloses a manual knob, clamp plate and support frame, the clamp plate with support frame fixed connection, the support frame is kept away from the one end and the work piece fixed connection of clamp plate, manual knob includes integrated into one piece's knob piece and screw rod, be equipped with the activity hole on the clamp plate, the aperture in activity hole is greater than the external diameter of screw rod, be provided with gland nut on the screw rod, the clamp plate is located the knob piece with between the gland nut.

According to the scheme, the support frame is used for limiting the manual knob, and the manual knob is prevented from falling when the machine type is disassembled and switched. The matching length of the screw rod and the workpiece is manually adjusted through the knob block, so that the workpiece and the machine type are connected, locked or separated. Through gland nut with the clamp plate cooperation realizes spacing anti-drop, and then saves debugging personnel's operating time, improves production efficiency. The movable hole is used for limiting the screw rod and providing a certain movable space for the screw rod at the same time, so that the manual knob can freely rotate.

Preferably, the diameter of the movable hole is smaller than the maximum outer diameter of the compression nut.

According to the scheme, the pressing nut is used for reliably limiting the manual knob and preventing the manual knob from falling off.

According to a preferable scheme, the support frame comprises a pair of C-shaped supports, the two C-shaped supports are symmetrically arranged by taking the axis of the movable hole as a center, the upper ends of the two C-shaped supports are welded and fixed with the pressure plate, and the lower ends of the two C-shaped supports are welded and fixed with the workpiece.

According to the scheme, the C-shaped structure is adopted, so that the production cost is saved, the space occupancy rate is reduced, and a certain moving space is provided for the manual knob.

According to a preferable scheme, the lower end of the knob block is further provided with a limiting round table, the screw penetrates through the limiting round table, and the outer diameter of the limiting round table is larger than the diameter of the movable hole.

According to the scheme, the limiting round platform is arranged to prevent the edge of the knob block from being worn when the knob block is in contact with the pressing plate, and meanwhile, a gap exists between the knob block and the pressing plate when the knob block is screwed down, so that debugging personnel can rotate the knob block conveniently.

Preferably, the compression nut is located in the middle section of the screw, and the compression nut and the screw are fixed in a welding mode.

According to the scheme, the compression nut is arranged in the middle section of the screw rod, so that the screw rod is ensured to have enough moving distance to be in threaded fit with a workpiece and a machine table.
