Description
Technical field
The utility model relates to mechanical equipment technical field, especially relates to wheels after a kind of Novel jack.
Background technology
Common packaged type jack, after generally having front wheel combination, wheels two groups are total to four wheels, and wherein, wheels are generally universal wheels, can change moving direction; But in the actual use procedure of packaged type jack, because some occasion ground is smooth not, in rear wheels two wheels may be caused to produce and to be uneven, normally cannot use jack, need to level up jack and could continue to use; Also likely ground insufficient strength, causes sinking of ground when jack load, and this can cause jack jacking direction to change and generation accident.
Summary of the invention
The utility model in use runs into the uneven and problem that self cannot adjust in ground to solve movable jack, provides a kind of structure simple, use safety, can self-adaptative adjustment, improves wheels after the Novel jack of stability.
To achieve these goals, the utility model is by the following technical solutions: wheels after a kind of Novel jack, wheels after comprising two groups, described rear wheels comprise universal wheels, wheel carrier, universal wheels, wheel carrier adopts tie bolt, captive nut connects, described rear wheels also comprise guide pin bushing, Compress Spring, described guide pin bushing is tubulose, described guide pin bushing one end and wheel carrier are fixed, the described guide pin bushing other end is provided with end cap, described end cap is provided with the through hole that can hold tie bolt and pass, described tie bolt body is provided with detouchable locating button, described tie bolt body is also provided with the step coordinated with Compress Spring, described tie bolt body afterbody is provided with the screw thread coordinated with captive nut, described locating button is located between universal wheels and wheel carrier, described Compress Spring is located between guide pin bushing rubbing surface of end cover and tie bolt step, described captive nut is provided with spacing between its bottom end face and guide pin bushing end cap lateral surface after tightening on tie bolt.In prior art, tie bolt is each passed through universal wheels, with captive nut, the two is fixed together after wheel carrier, wheel carrier is fixedly connected on jack body, this programme passes universal wheels at tie bolt, on the basis the two is fixed together with captive nut after wheel carrier, increase the guide pin bushing on wheel carrier, special construction design is carried out to tie bolt, utilize Compress Spring, and reserved adjustment spacing, make to be no longer cannot move after fixing between universal wheels and wheel carrier, but spacing can be adjusted, so, when running into the rugged situation in ground, jack deadweight and Compress Spring elastic force combined action under, universal wheels can adjust high and low position automatically, jack can normally be used, add stability.
As preferably, the spacing between described captive nut bottom end face and guide pin bushing end cap lateral surface is 5mm-8mm.Limitting by jack height, the adjustable scope of jack is little, and it is nonsensical that spacing is too little, but spacing is excessive does not also accomplish, so 5mm-8mm is range of choices, gets 6mm for best.
As preferably, described guide pin bushing and wheel carrier fixed end are provided with positioning step, and described positioning step external diameter and wheel carrier close-fitting, described guide pin bushing and wheel carrier are welded and fixed.Guide pin bushing and wheel carrier need fixing, coaxial with the hole supplying tie bolt to pass on wheel carrier owing to will ensure the through hole on guide pin bushing end cap, adopt positioning step, positioning step with the hole close-fitting on wheel carrier, then can be welded, just can ensure the right alignment in hole.
As preferably, described guide pin bushing is integral type structure.Integral structure intensity is large, and precision is high, is convenient to manufacture.
Therefore, the utility model has following beneficial effect: (1) structure is simple, use safety; (2) environment for use can be adapted to by self-adaptative adjustment; (3) jack stability is improved.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the detonation configuration schematic diagram of wheels after a group in Fig. 1.
In figure: 1, universal wheels 2, wheel carrier 3, tie bolt 4, captive nut
5, guide pin bushing 6, Compress Spring 7, end cap 8, through hole 9, locating button
10, step 11, spacing 12, positioning step.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, in embodiment shown in Fig. 2, wheels after a kind of Novel jack, wheels after comprising two groups, rear wheels comprise universal wheels 1, wheel carrier 2, universal wheels 1, wheel carrier 2 adopts tie bolt 3, captive nut 4 connects, rear wheels also comprise guide pin bushing 5, Compress Spring 6, guide pin bushing 5 is tubulose, guide pin bushing 5 one end and wheel carrier 2 are fixed, guide pin bushing 5 other end is provided with end cap 7, end cap 7 is provided with the through hole 8 that can hold tie bolt 3 and pass, tie bolt 3 body is provided with detouchable locating button 9, tie bolt 3 body is also provided with the step 10 coordinated with Compress Spring 6, tie bolt 3 body afterbody is provided with the screw thread coordinated with captive nut 4, locating button 9 is located between universal wheels 1 and wheel carrier 2, Compress Spring 6 is located between guide pin bushing 5 end cap 7 medial surface and tie bolt 3 step 10, captive nut 4 is provided with spacing 11 between its bottom end face and guide pin bushing 5 end cap 7 lateral surface after tightening on tie bolt 3, spacing 11 is apart from being 6mm, guide pin bushing 5 and wheel carrier 2 fixed end are provided with positioning step 12, positioning step 12 external diameter and wheel carrier 2 close-fitting, guide pin bushing 5 and wheel carrier 2 are welded and fixed, guide pin bushing 5 is integral type structure.
Specific implementation process is, in this jack use procedure, if run into ground injustice, when running into the rugged situation in ground, under the elastic force combined action of jack deadweight and Compress Spring 6, universal wheels 1 can adjust high and low position automatically, keep the contact with ground, make jack body keep balance, normally can use, add the stability of jack.
