The other end of the driving screw rod is fixedly connected with a ball pin. A spherical-surface connection pair is formed by the ball pin and the ball pin boss. The self-locking type feed inlet width adjusting device has the advantages of reasonable design, simple structure, convenient operation, small size, light weight, convenient disassembly, easy maintenance, long service life, wide application range, low production cost, and convenient popularization and application.
Description
Technical field
The utility model belongs to and relates to a kind of width adjusting apparatus, is specifically related to a kind of retractor device with auto-lock function.
Background technology
Along with the development of Building Trade in China, the construction materials such as timber, plasterboard need to be processed to regular shape in enormous quantities on power planer or sawing machine.Construction material need to be determined true edge when processed, then according to the width of the adjusted size charging aperture of machined material.Suitable charging aperture width can make material sideslip not in the process of processing, and machining accuracy is improved.Scarcely there is width adjusting apparatus in the workbench charging aperture of current planer or sawing machine, individual work platform charging aperture is with width adjusting apparatus, but these device ubiquity designs are unreasonable, complex structure, the problems such as adjusting operation inconvenience.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of self-locking charging aperture width adjusting apparatus is provided, and it is reasonable in design, simple in structure, easy to operate, volume is small and exquisite, lightweight, easy accessibility, be convenient to safeguard, long service life, applied widely, production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of self-locking charging aperture width adjusting apparatus, comprise and it is characterized in that lever arm and the frame playing fixed supporting role: also comprise the drive screw for driving described lever arm to move forward and backward, the inner thread sleeve matching with described drive screw, for fixedly mounting the bearing of described inner thread sleeve and being fixedly mounted on the ball pin seat on described lever arm; In described frame, be installed with described bearing, on described bearing, be installed with described inner thread sleeve, in described inner thread sleeve, be provided with described drive screw, described drive screw one end is installed with rolling disc, described rolling disc outer ledge place is provided with for driving the driving handle of described turn disc, the described drive screw other end is fixedly connected with ball pin, and described ball pin and described ball pin seat form sphere auxiliary connection.
Above-mentioned self-locking charging aperture width adjusting apparatus, is characterized in that: described ball pin seat welds or is fixedly connected with described lever arm by screw thread.
Above-mentioned self-locking charging aperture width adjusting apparatus, is characterized in that: described bearing welds or is fixedly connected with described frame by screw thread.
The utility model compared with prior art has the following advantages:
(1) design of this self-locking charging aperture width adjusting apparatus is very reasonable, simple and compact for structure, and operating personnel only need rotate rolling disc can complete width adjustment, and this device also has auto-lock function, uses very easy.
(2) this self-locking charging aperture width adjusting apparatus volume is small and exquisite, lightweight, and easy accessibility is convenient to safeguard and carrying.
(3) this self-locking charging aperture width adjusting apparatus is in use without rigid shock, long service life, and the scope of application is very extensive.
(4) production technology of this self-locking charging aperture width adjusting apparatus is simple, and requirement on machining accuracy is not high, and a lot of parts are all convenient to produce very much, purchase, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.

The specific embodiment
A kind of self-locking charging aperture width adjusting apparatus as depicted in figs. 1 and 2, comprise lever arm 1 and the frame 4 playing fixed supporting role, also comprise the drive screw 2 for driving described lever arm 1 to move forward and backward, the inner thread sleeve 3 matching with described drive screw 2, for fixedly mounting the bearing 7 of described inner thread sleeve 3 and being fixedly mounted on the ball pin seat 9 on described lever arm 1; In described frame 4, be installed with described bearing 7, on described bearing 7, be installed with described inner thread sleeve 3, in described inner thread sleeve 3, be provided with described drive screw 2, described drive screw 2 one end are installed with rolling disc 5, described rolling disc 5 outer ledge places are provided with the driving handle 6 for driving described rolling disc 5 to rotate, described drive screw 2 other ends are fixedly connected with ball pin 8, and described ball pin 8 forms sphere auxiliary connection with described ball pin seat 9.
In the present embodiment, described ball pin seat 9 welds or is fixedly connected with described lever arm 1 by screw thread.
In the present embodiment, described bearing 7 welds or is fixedly connected with described frame 4 by screw thread.
The course of work of the utility model self-locking charging aperture width adjusting apparatus is: first this self-locking charging aperture width adjusting apparatus is fixedly mounted on to operating position, operator is rotated in the forward rolling disc 5 by driving handle 6, rolling disc 5 drives drive screw 2 to be rotated in the forward in inner thread sleeve 3, drive screw 2 drives lever arm 1 to move forward, thereby charging aperture is diminished.Reverse rotation rolling disc 5, can make drive screw 2 drive lever arm 1 to move backward, thereby makes charging aperture become large.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every any simple modification, change and equivalent structure transformation of above embodiment being done according to the utility model technical spirit, all still belongs in the protection domain of technical solutions of the utility model.
