Description
Technical field
Physical Experiment equipment technical field is the utility model is related to, specially a kind of Height Adjustable tripod.
Background technology
Tripod can be often used in Physical Experiment, such as, it is necessary to use alcolhol burner heating during observation flame reaction
Different metals, tripod support alcolhol burner is at this moment just needed to carry out heating metal, because the height of tripod is usually to fix,
So cause many experiments to be difficult to complete, otherwise exactly comparatively laborious tripod can adjust height, it is inconvenient during regulation, it is high
The regulation of degree is important for tripod, and the tripod of a convenient regulation height can improve the efficiency of experiment.
Utility model content
The purpose of this utility model is to provide a kind of Height Adjustable tripod, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides following technical scheme：A kind of Height Adjustable tripod, including
Base, the middle of the base install support column, support column inner chamber grafting expansion link, and rack is welded in the expansion link side, described
Installation two contiguous blocks in side at the top of support column, the contiguous block middle part grafting rotating shaft, the fixedly sleeved gear in the rotating shaft middle part,
The gear is ratcheting through support column side and rack, and described rotating shaft one end is connected with crank, is welded at the top of the expansion link
The bottom of guardrail bottom plate, the corner of the guardrail bottom plate are connected by spring with susceptor surface, and the guardrail bottom plate surrounding passes through
The upper guardrail of support bar welding.
Preferably, the spring has four.
Preferably, support column inner chamber side is provided with rectangular recess, rack clamping with groove.
Preferably, the rotating shaft is provided with bearing with contiguous block junction.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, is rotated by crank
Band moving gear, gear driving rack cause expansion link regulation height, and principle is simple, simple structure, practical, while coordinates four
The spring at angle, spring can provide some elastic force, while can make it that guardrail is more stable, and the utility model is adapted to widely push away
It is wide practical.
Brief description of the drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model support column arrangement top view.
Fig. 3 is guard bar structure top view on the utility model.
In figure：Guardrail, 2 support bars, 3 guardrail bottom plates, 4 expansion links, 5 springs, 6 racks, 7 bases, 8 support columns, 9 connect on 1
Connect block, 10 cranks, 11 gears, 12 rotating shafts.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of Height Adjustable tripod, including bottom
Rack 6 is welded in seat 7, the middle part of the base 7 installation support column 8, the inner chamber grafting expansion link 4 of support column 8, the side of expansion link 4,
The inner chamber side of support column 8 is provided with rectangular recess, the clamping of rack 6 with groove, the top side of support column 8 installs two
Contiguous block 9, the middle part grafting rotating shaft 12 of contiguous block 9, the rotating shaft 12 and the junction of contiguous block 9 are provided with bearing, described turn
The fixedly sleeved gear 11 in the middle part of axle 12, the gear 11 is ratcheting through the side of support column 8 and rack 6, and described one end of rotating shaft 12 connects
Crank 10 is connected to, the top of expansion link 4 is welded on the bottom of guardrail bottom plate 3, and the corner of the guardrail bottom plate 3 passes through spring 5
It is connected with the surface of base 7, the spring 5 there are four, and the surrounding of guardrail bottom plate 3 welds upper guardrail 1 by support bar 2.
In summary：During practical tripod, height, the rack 6 and tooth of the side of expansion link 4 can be adjusted by expansion link 4
Take turns 11 ratcheting, rotated by rotating crank 10 with moving gear 11, gear 11 can drive rack 11 to be moved upwardly or downwardly, simultaneously
Coordinate the spring 5 of 3 four jiaos of guardrail bottom plate both to have improved the stability of guardrail, certain bullet can also be given in elevating guardrail
Power.
Crank 10 is collapsible Z-type structure, and the height of expansion link 4 can be fixed by coordinating to interior folding and contiguous block 9.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
