Description
Technical field
The utility model belongs to the fixing device technical field, especially relates to a kind of shank fixing device.
Background technique
Shank has been widely used in various field at present, and shank comprises loop bar and the inserted link that is plugged on the loop bar, and inserted link can freely stretch in loop bar, so just can adjust the length of shank very easily.
When the length adjustment of shank just need be fixed it to suitable, the simplest means of fixation is offered screw exactly on loop bar, screw rod screws in from screw, utilize the end conflict of screw rod on inserted link, to realize the fixing of inserted link, adopt fixedly inserted link of this mode, wherein deficiency is: 1, directly conflict and be very easy to the surface of damage inserted link on the surface of inserted link in the end of screw rod; If 2 use shank as bearing bar, because of the surface of contact of screw rod end and plunger surface very little (if circular shank then surface of contact can be littler), when the gravity that bears when shank is big, will oppress in the inserted link retraction loop bar, cause plunger surface scratch to occur, even occur dangerous; 3, present most of inserted link is hollow, and when screw rod screwed in from screw, as firmly excessive, screw rod can be with inserted link extrusion-deformation.
The different shank fixing device of multiple structure is also arranged in the market, and complex structure, use bother, bearing capacity is little, the shortcoming of poor stability but all exist.
The model utility content
At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of shank fixing device, and it has characteristics simple in structure, easy to use, that bearing capacity is strong, safe.
To achieve these goals, the technological scheme that the utility model adopted is: the shank fixing device, comprise screw rod and the hand-screw handle that is connected with screw rod, it also comprises fixed block and Fastener, fixed block comprises holding base and the pole socket that is connected with holding base, the through hole of pole socket inside matches with shank, and the inside of holding base communicates with the through hole of pole socket inside, and holding base is provided with screw and guide rail; Fastener comprises cover plate and the fixture block that is connected with cover plate, and cover plate is positioned on the guide rail, and can move along the guide rail straight line, and fixture block matches with shank; A be connected end of hand-screw handle of screw rod is positioned at the holding base outside, and the other end passes screw and protrudes into holding base inside, matches with fixture block in its end.
Described fixed block adopts integrally moulded.
Described Fastener adopts integrally moulded.
After adopting said structure, the utility model is compared the advantage that is had with prior art and is: the utility model only is made of fixed block, Fastener, screw rod and hand-screw handle, and it is simple in structure, easy to use.Fixed block and Fastener all adopt integrally moulded, can not damage the surface of shank.The cooperation of pole socket and fixture block is wrapped in the joint of shank wherein and closely cooperates, and its surface of contact is very big, can guarantee that shank can bear very strong pressure, and Security greatly improves, simultaneously can be with shank extrusion-deformation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is a sectional view of the present utility model;
Fig. 3 is the utility model embodiment's a sectional view.
Among the figure: 11, holding base; 12, pole socket; 13, guide rail; 21, cover plate; 22, fixture block; 30, screw rod; 31, hand-screw handle; 100, loop bar; 200, inserted link.
Embodiment
The following stated only is preferred embodiment of the present utility model; therefore do not limit protection domain of the present utility model; for convenience of description; shank among the embodiment is in vertical state; shank is an example with the circular loop bar 100 of circular inserted link 200 grafting; circular inserted link 200 is last, and circular loop bar 100 is following.
Embodiment, see that Fig. 1 is to shown in Figure 3: the shank fixing device, comprise fixed block, Fastener, screw rod 30 and the hand-screw handle 31 that is connected with screw rod 30, fixed block and Fastener all adopt integrally moulded.Fixed block comprise holding base 11 and with holding base 11 integrated pole sockets 12, the through hole of pole socket 12 inside matches with shank, loop bar 100 is plugged on pole socket 12 bottoms, inserted link 200 is inserted into the loop bar 100 from pole socket 12 tops, the inside of holding base 11 communicates with the through hole of pole socket 12 inside, the upper end of holding base 11 forms guide rail 13, offers screw with the opposite side that pole socket 12 links to each other.Fastener comprise cover plate 21 and with cover plate 21 integrated fixture blocks 22, cover plate 21 matches with guide rail 13, cover plate 21 fits on the guide rail 13 and can move along guide rail 13 straight lines, fixture block 22 and the circular arc of shank inserted link 200 places of fitting for indent, and fixture block 22 can fit tightly with inserted link 200.A be connected end of hand-screw handle 31 of screw rod 30 is positioned at holding base 11 outsides, and the other end passes screw and protrudes into holding base 11 inside, and its end can promote fixture block 22 and move.
During use, earlier shank is adjusted to proper height, rotate hand-screw handle 31 then, screw rod 30 is along with the rotation of hand-screw handle 31 slowly inwardly advances, on fixture block 22 is conflicted in the end of screw rod 30, will head on fixture block 22 and advance, after fixture block 22 and inserted link 200 fit tightly, promptly realize the fixing of inserted link 200.
Assemble shank of the present utility model and can be applicable to various field, for example shank is used on Medical stand as lifting bar, during assembling, the medicine bottle hanger is fixed on the upper end of inserted link 200, loop bar 100 lower ends are solid on base, can adjust the height of medicine bottle hanger very easily by the utility model, shank can bear the gravity of a plurality of medicine bottles, and Security is very good.
Of particular note: the utility model also is applicable to the shank of other shape, as use square shank, only need with the through hole of pole socket 12 inside be arranged to match with square shank square, simultaneously fixture block 22 is made as the square of indent with the square shank place of fitting and gets final product.
