Abstract
The utility model discloses a jaw type hydraulic puller, which particularly relates to a retaining structure of a central thread spindle of the hydraulic puller. The retaining mechanism of the hydraulic puller comprises a fixing disk and a central thread spindle thereof, the fixing disk is provided with a groove, and the two walls of the groove are provided with hole sites. The central part of the retaining block is provided with a hole and is fixed in the groove by a spindle. One end of the retaining block is connected with a spring, and the other end of the retaining block is matched with a thread groove of the thread spindle. The utility model has the advantages of simple structure, easy use, etc.
Description
The hydraulic pressure that the utility model relates to a kind of pawl formula draws horse, is specifically related to the thrust structure that a kind of hydraulic pressure draws Malaysia and China's heart thread spindle.
Existing pawl formula machinery draws horse simple in structure on the market, catches when three pawls and is drawn thing, and fixed disk cooperates precession with the thread spindle at center with trapezoidal thread, when withdrawing from, need screw out with screw thread equally, and is cumbersome, when turn length is longer, then uses extremely inconvenient.
The purpose of this utility model is to provide a kind of a kind of hydraulic pressure simple in structure, easy to use to draw the stopping mechanism of horse.
The purpose of this utility model is achieved like this, hydraulic pressure draws the stopping mechanism of horse, comprise fixed disk and center thread spindle thereof, it is characterized in that: a groove is arranged on the fixed disk, porose position on two cell walls, the retreat stop block central part has a hole, and is fixed in the groove with bearing pin, retreat stop block one end is connected with spring, and the other end cooperates with the thread groove of thread spindle.
One projection is arranged on the retreat stop block, and projection cooperates with the spring mesopore, and the spring other end is fixed in bottom portion of groove.
The utlity model has following advantage: only set up a thrust structure of forming by retreat stop block, bearing pin, spring, and removed the screw thread of fixed disk centre bore at once former drawing, simple in structure; When the center of fixed disk thread spindle pushed away forward, stopping mechanism was inoperative, advanced smoothly; When withdrawing from, can screw out with screw thread, also can compress spring, the screw thread of retreat stop block and thread spindle is disengaged, then thread spindle can be free to slide in the fixed disk centre bore, and is easy to use.
Below in conjunction with drawings and Examples the utility model is done step detailed description.
Fig. 1 is the front view of the utility model embodiment
As shown in Figure 1, the groove of a U type on the fixed disk 1 has position, a hole on the left cell wall, a screwed hole is arranged on the right cell wall, and retreat stop block 2 middle positions have position, a hole, and bearing pin 3 one ends are screw threads, and retreat stop block 2 is fixed on the fixed disk 1 by bearing pin 3.
One end of retreat stop block 2 has a projection, cooperate with the medium pore of spring 4, the other end of spring 4 is fixed on the bottom of U type groove, the other end of retreat stop block 2 inserts in the trapezoidal thread groove of thread spindle 5, retreat stop block 2 projection tops are provided with a flat board by piece 6, and it is moving dull and stereotyped by piece 6 to press...with one's finger, compression spring 4, the trapezoidal thread groove of retreat stop block end and thread spindle 5 is thrown off, and then thread spindle 5 can be free to slide in the centre bore of fixed disk 1.
When thread spindle 5 promoted forward, the trapezoidal thread groove was released the end of retreat stop block 2, compresses spring 4 simultaneously, and like this, stopping mechanism is inoperative in the process before thread spindle pushes away, and process is not interrupted before pushing away.
Claims (2)
1, hydraulic pressure draws the stopping mechanism of horse, comprise fixed disk and center thread spindle thereof, it is characterized in that: a groove is arranged on the fixed disk, porose position on two cell walls, the retreat stop block central part has a hole, and be fixed in the groove with bearing pin, retreat stop block one end is connected with spring, and the other end cooperates with the thread groove of thread spindle.
2, hydraulic pressure according to claim 1 draws the stopping mechanism of horse, it is characterized in that: a projection is arranged on the retreat stop block, and projection cooperates with the spring mesopore, and the spring other end is fixed in bottom portion of groove.
