Abstract
This utility model relates to full-automatic sewing machine field, particularly relates to the middle depression bar of middle presser bar lifting mechanisms.Depression bar in the full-automatic template sewing machine of one of the present utility model, the upper end of middle depression bar is provided with female thread, and described female thread is for being connected with pressure regulation guide rod.This utility model has the advantage improving pressure regulation guide rod intensity.
Description
Technical field
This utility model relates to full-automatic sewing machine field, particularly relates to the middle depression bar of middle presser bar lifting mechanisms.
Background technology
In prior art, the middle pressure hoisting mechanism of full-automatic template sewing machine is that computer controls automatic lifting, and its structure is:
One end of pressure regulation guide rod is placed in the bar chamber of middle depression bar, and the other end of pressure regulation guide rod is connected with hoisting mechanism, due to pressure regulation guide rod
Restricted diameter in the internal diameter in the bar chamber of middle depression bar, cause pressure regulation guide rod the most easily broken, considerably increase the fault rate of machine, increase
The big cost of user, also reduces the efficiency of work simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of middle depression bar improving pressure regulation guide rod intensity.
Of the present utility model disclose full-automatic template sewing machine with in depression bar, the upper end of middle depression bar is provided with female thread, institute
State female thread for being connected with pressure regulation guide rod.
The length of medium pressure bar is less than or equal to 200mm and more than or equal to 50mm.The external diameter of medium pressure bar is less than or equal to
15mm and more than or equal to 6mm.Preferably length 105mm of medium pressure bar, the external diameter 9mm of medium pressure bar.
This utility model has the advantage that
1, it is connected because of middle depression bar of the present utility model and pressure regulation guide rod so that the globality of middle depression bar lifting device is more
By force.
2 secondly because middle depression bar and pressure regulation guide rod are connected, and middle depression bar moves and stress together with pressure regulation guide rod so that
The lifting intensity of pressure regulation guide rod is greatly improved, and fastness the most significantly strengthens.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model structure.
Fig. 2 is that this utility model uses view.
Scheme of installation when Fig. 3 is this utility model use.
In figure:
Depression bar in 1,10 female threads, the external diameter of depression bar in D, the length of depression bar in L,
2 pressure regulation guide rods, 21 cap portions,
3 springs, 4 pressure regulation guide rod pipe boxes, 41 steps,
5 cylinders fix seat, and 51 cylinders fix nut,
6 cylinders, 61 piston rods, 7 nuts.
Detailed description of the invention
Being described further this utility model below in conjunction with the accompanying drawings, following example are only preference, are not right
Scope of the present utility model is any limitation as, on the contrary, its objective is to wish to contain various change and have being arranged in of equality
This utility model is intended in the category of the scope of the claims applied for.
Embodiment 1: this utility model is described further by 1 to Fig. 3 below in conjunction with the accompanying drawings:
Depression bar 1 in a kind of full-automatic template sewing machine, the upper end of middle depression bar is provided with female thread 10, length L of middle depression bar
For 105mm, the outer diameter D of middle depression bar is 9mm.
Depression bar lifting device in depression bar 1 is applied to full-automatic template sewing machine in the full-automatic template sewing machine of one
Time: the upper end of pressure regulation guide rod 2 passes pressure regulation guide rod pipe box 4, and the cap portion 21 of the upper end of pressure regulation guide rod 2 is placed in pressure regulation guide rod pipe box 4
In, spring 3 is sheathed on pressure regulation guide rod 2, and the cap portion 21 of the upper end of pressure regulation guide rod 2 coordinates with the step 41 of pressure regulation guide rod pipe box 4,
41 position-limiting actions of step so that the cap portion 21 of pressure regulation guide rod 2 is placed in pressure regulation guide rod pipe box 4 all the time.Middle depression bar 1 female thread with
The external screw thread of pressure regulation guide rod 2 is connected and passes through nut 7 and fixes.Spring 3 between pressure regulation leader casing 4 and middle depression bar 1, when
When middle depression bar 1 moves up and down together with pressure regulation guide rod 2, spring 3 is compressed between pressure regulation leader casing 4 and middle depression bar 1.Pneumatic lifting
Piston rod 61 one end of the cylinder 6 rising mechanism is fixed seat 5 through cylinder and is connected with the threaded upper ends of pressure regulation guide rod pipe box 4.
