Abstract
The utility model relates to the technical field of a gas spring, in particular to an automatic resetting gas spring. The automatic resetting gas spring comprises an outer bushing, an inner tube which is sleeved inside the outer bushing, a piston and a piston rod, wherein the piston and the piston rod are arranged in the inner tube, one side, adjacent to the piston, inside the outer bushing is provided with an air cylinder, a guide sleeve is arranged between the outer bushing and the inner tube, the guide sleeve is fixedly connected with the outer bushing through a cylindrical pin, one side of the guide sleeve is provided with a slide sleeve, a bearing is arranged outside the inner tube, the slide sleeve is arranged between the bearing and the guide sleeve, a compression spring is also arranged outside the inner tube, and the compression spring is arranged between the bearing and the air cylinder. According to the automatic resetting gas spring, through the matching of the guide sleeve and the slide sleeve, the automatic resetting effect can be well realized, the structure is reasonable to set, the performance is excellent, and the automatic resetting gas spring can be rapidly reset in the application process to enter a next operation, so that the application field and the application range of the automatic resetting gas spring can be effectively enlarged .
Description
Technical field
The utility model relates to air spring technical field, especially the one air spring that automatically resets.
Background technique
Air spring is that one can labour-saving lifting spring, can be divided into can self-locking air spring (as the bottom elevation of seat, executive chair rear backrest etc.), can not self-locking air spring (as the lifting of car trunk, closet door is supported), the structure of air spring is mainly made up of sleeve, piston and piston rod etc., in sleeve, add high-pressure air or high pressure nitrogen, do not wait and produce pressure reduction because side face of piston ring is long-pending, promote piston and piston rod and move and support people or weight.The air spring that automatically resets is the one of air spring, application in medical apparatus is very extensive, the most complex structure of the existing air spring that automatically resets, fabricating cost is high, becomes the focus in row therefore research and develop a kind of simple in structure air spring that automatically resets on the basis of the good reseting performance of maintenance.
Model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of simple in structure, the air spring that automatically resets that can reset rapidly.
The utility model solves the technological scheme that its technical problem adopts: the one air spring that automatically resets, comprise outer sleeve, be sheathed on the inner core in outer sleeve and be positioned at piston and the piston rod of inner core, a side near piston in described outer sleeve has pneumatic cylinder, between described outer sleeve and inner core, be provided with guide sleeve, described guide sleeve is fixedly connected with outer sleeve by straight pin, one side of guide sleeve is provided with sliding sleeve, described inner core has bearing outward, sliding sleeve is between bearing and guide sleeve, described inner core also has Compress Spring outward, described Compress Spring is between bearing and pneumatic cylinder.
Further, in such scheme, the front end of described pneumatic cylinder is provided with gas-pressure ring.
The beneficial effects of the utility model are: the one described in the utility model air spring that automatically resets, by being used in conjunction with of guide sleeve and sliding sleeve, can well realize the effect that automatically resets, structure arranges rationally, function admirable, the utility model in use can be replied rapidly, enter next working level, effectively widened the utility model application and application area.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. outer sleeve, 2. inner core, 3. piston, 4. piston rod, 5. pneumatic cylinder, 6. guide sleeve, 7. straight pin, 8. sliding sleeve, 9. Compress Spring, 21. bearings, 51. gas-pressure rings.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The air spring that automatically resets of one as shown in Figure 1, comprise outer sleeve 1, be sheathed on the inner core 2 in outer sleeve 1 and be positioned at piston 3 and the piston rod 4 of inner core 2, the interior side near piston 3 of outer sleeve 1 has pneumatic cylinder 5, between outer sleeve 1 and inner core 2, be provided with guide sleeve 6, guide sleeve 6 is fixedly connected with outer sleeve 1 by straight pin 7, one side of guide sleeve 6 is provided with sliding sleeve 8, outside inner core 2, there is bearing 21, sliding sleeve 8 is between bearing 21 and guide sleeve 6, inner core 2 is also outer has Compress Spring 9, and Compress Spring 9 is between bearing 21 and pneumatic cylinder 5.
Further, in such scheme, the front end of pneumatic cylinder 5 is provided with gas-pressure ring 51.
Working principle: use the utility model, pneumatic cylinder 5 internal air pressures are pushed piston 3 to move left to, piston rod 4 is also moved to the left, Compress Spring 9 is in compressive state and promote sliding sleeve 8 and a part for guide sleeve 6 is moved to the left, when return, because guide sleeve 6 is fixedly connected with outer sleeve 1 by straight pin 7, reset rapidly to a part of guide sleeve 6 moving to left, drive sliding sleeve 8 to reset, piston 3 resets rapidly for 9 times at Compress Spring, can carry out next action simultaneously.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this model utility technological thought, carry out various change and modification completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
