Abstract
The utility model relates to a screw-thread self-locking type quick-assembling mechanism, which is composed of connected parts 1 and 2, a screw rod 3, locking blocks 4, a fixed shaft 5, a pin shaft 6, a spacing part 7 and a spring 8. When the utility model is used, the screw rod 3 is rotated to drive locking blocks 4 to move, and quick assembling and disassembling of two connected parts are rapidly realized. The utility model has the advantages of convenient use, high efficiency and safety. The utility model can be used for a heavy-duty driving shaft which needs to be frequently disassembled.
Description
The utility model relates to a kind of fast mounting mechanism, particularly a kind of screw thread self-locking quick mounting mechanism.
At present, on the heavy load transmission axle of often dismounting, as the widely used fast mounting mechanism of occasions such as rolling mill, testing stand: coupled 9,10 makes it to join together fast by retaining ring 11 with closing bolt 12.This existing fast mounting mechanism, easily loosening closing bolt, operating reliability is poor, and when mounting or dismounting, retaining ring will choose to move, and the gas of both having required great effort is also dangerous.
The utility model is exactly to realize the purpose of quicker mounting or dismounting in order to reach safety and reliability ground, and a kind of screw thread self-locking quick mounting mechanism is provided.
The purpose of this utility model is achieved in that by a kind of screw thread self-locking quick mounting mechanism of coupled to be formed.Be characterized in: coupled along end face axial designed inward one-sided in the ring locking face; Outer rim design has the latch segment of spill locking slot, when mounted, its spill locking slot two sides, locking contacts with ring locking face in two coupled one-sided respectively; Latch segment is designed to the 2-4 piece, and it is right to be symmetrically distributed into 1-2; Restrict mutually by locating part between the latch segment; Design has spring, the elastic force of spring to make latch segment and coupled auto lock on the latch segment; Be limited in a screw rod on coupled, the one end is a sinistral external thread, and an end is the dextrorotation external screw thread, matches with a pair of internal thread latch segment with different rotation directions respectively.
The utility model screw thread self-locking quick mounting mechanism has the following advantages:
The first, rotary screw drives the latch segment motion, has realized quick mounting or dismounting at once for two coupled.
The second, the operational reliability height, this be since on the latch segment design spring is arranged, during operation, can keep latch segment and coupled 's locking state automatically.
The 3rd, before and after the mounting or dismounting, all parts still are connected on coupled, need not take care of separately and there is fragmentary loose mail.
The 4th, the structure parts all design in coupled abdominal cavity, make whole specious.
Fig. 1 is existing fast mounting mechanism structural map
Fig. 2 is a structural map of the present utility model
For an embodiment, contrast accompanying drawing 2 is illustrated below.
Among the figure, latch segment 4 its spill locking slots when mounted, the two sides locking that contacts with ring locking face in two coupled 1,2 one-sided respectively; Screw rod 3 is limited on coupled 1 by fixed axis 5 and bearing pin 6, one end design sinistral external thread, the other end is designed to the dextrorotation external screw thread, respectively with have different rotation direction internal thread latch segments 4 and match; Locating part 7 is to guarantee that each latch segment 4 together moves when rotary screw 3; Design has spring 8, its spring tension can keep latch segment 4 and coupled 1,2 locking state automatically on the latch segment 4.During use, rotary screw 3 can be realized two coupled 1,2 quick mounting or dismounting rapidly.
