Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, expansion link 1 comprises external extension bar 11 and is entrenched in the interior expansion link 12 of external extension bar 11 inside, and external extension bar 11 and interior expansion link 12 are all be made up of square steel, and the top of interior expansion link 12 is provided with the first screw mechanism 13.External extension bar 11 be provided with the top that at least 1 the first connecting hole 111, first connecting hole 111 is preferably located at external extension bar 11, the collapsing length that expansion link 1 can be made like this to reach maximum, can ensure again the stability of expansion link 1.Interior expansion link 12 is provided with at least 2 the second connecting hole 121, second connecting holes 121 and uniformly distributes on interior expansion link 12, and the structural stability of expansion link 12 in ensureing like this, also can calculate the length of expansion link 1 simultaneously fast.Distance between second connecting hole 121 is generally 3 ~ 10cm, when needing the height of expansion link 1 to fix, the fixture 14 matched with the first connecting hole 111 and the second connecting hole 121 is fixed, fixture 14 can be latch or bolt, when for the second nut (not illustrating in the drawings) be meshed with bolt can also be had during bolt, just latch can be inserted the first connecting hole 111 and the second corresponding with it connecting hole 121 if fixture 14 is latch, like this, expansion link 12 is just fixed, expansion link 1 after highly fixing has very high mechanical support intensity.The side that first connecting hole 111 and the second connecting hole 121 are at least corresponding is through hole, and opposite side is through hole or blind hole or does not have Kong Junke.First connecting hole 111 and the second connecting hole 121 are pin-and-hole or screwed hole, as improvement, the both sides of the second connecting hole 121 are through hole and the side of the first connecting hole 111 is through hole opposite side is blind hole or through hole, interior expansion link 12 just can more firmly be fixed on external extension bar 11 by such fixture 14, further, make further improvement on this basis, first connecting hole 111 side is pin-and-hole, the blind hole of opposite side or through hole are screwed hole, two side through hole of the second connecting hole 121 are pin-and-hole, insert the second connecting hole 121 from the pin-and-hole of the first connecting hole 111 when being bolted like this to screw at the screwed hole of opposite side, more convenient to operate, also the instability of the loosening expansion link 1 caused of fixture 14 can be prevented.When needing the height of adjustable telescopic rod 1, fixture 14 is removed, interior expansion link 12 is pulled to carry out Telescopic moving, when reaching required height, fixture 14 is inserted external extension bar 11 the first connecting hole 111 and corresponding with the first connecting hole 111 in the second connecting hole 121 of expansion link 12, just the height of expansion link 1 can be fixed.Have certain spacing between the second connecting hole 121 due to interior expansion link 12, expansion link 1 to the full extent close to required height, now can only just can need the height by regulating the first screw mechanism 13 to finely tune expansion link 1.First screw mechanism 13 comprises screw rod 131, first nut 132 and support set 133, wherein, first nut 132 and screw rod 131 are meshed, first nut 132 can be wing nut, or handle (not illustrating in the drawings) is set up on the first nut 132, need or not directly to rotate the first nut 132 by instrument during the height of finely tuning expansion link 1 and regulate.The top of screw rod 131 is provided with supporting plate 134, the lower end of screw rod 131 is provided with limiting section 135, this limiting section 135 can limit screw rod 131 and rotate relative to inside spin bar 12, now can realize the first nut 132 to rotate relative to screw rod 131, increase or shorten the distance between the first nut 132 to supporting plate 134 thus the height of adjustment expansion link 1, this limiting section 135 can be steel plate, also can be other conventional limiting sections, when limiting section 135 is steel plate, a block plate is welded respectively in the corresponding side of screw rod 131 lower end, when inside spin bar 12 is made for square steel, directly screw rod 131 is diagonally inserted inside spin bar 12, effectively can limit screw rod 131 to rotate relative to inside spin bar 12.Support set 133 is located on the screw rod 131 between the first nut 132 and limiting section 135, support set 133 can be linked in the top of interior expansion link 12, support set 133 can reduce the mechanical friction of the first nut 132 and interior expansion link 12 end, prevent the mechanical damage of the first nut 132 and interior expansion link 12 end, increase the application life of expansion link 1.As improvement, the bottom of expansion link 11 outside can also have additional the second screw mechanism (not illustrating in the drawings), this second screw mechanism is identical with the first screw mechanism structure, when needed this second screw mechanism is arranged on the bottom of expansion link 1.Just do not need when the height required for expansion link 1 is very high like this to regulate the first screw mechanism 13 that inside spin bar 12 is arranged, directly utilize the height of the second screw mechanism fine setting expansion link 1 of bottom.
As shown in Figure 2, the support set 133 of the first screw mechanism 13 is also provided with the first locking hole 136, the second locking hole 137 is provided with the first locking hole 136 corresponding site after support set 133 is enclosed within interior expansion link 12 top, first locking hole 136 is screwed hole, second locking hole 137 is pin-and-hole or screwed hole, screw rod 131 can hold out against by the lock bolt 15 matched with the first locking hole 136 and the second locking hole 137, so just effectively can prevent screw rod 131 from loosening, add the safety and stability of use.
As shown in Figure 3, a kind of discharging platform comprises platform 2 and support bar 3, support bar 3 is located at the side of platform 2, support bar 3 is detachable connection with platform 2, when not using discharging platform, support bar 3 can be dismantled, so just can reduce the volume of discharging platform, store and transport also convenient.Support bar 3 comprises 4 be parallel to each other expansion link 1 and some connecting rods 4, be connected as a single entity by connecting rod 4 between expansion link 1, be movable connection between expansion link 1 and connecting rod 4, such discharging platform convenient disassembly, dismounting after institute take up space little, be easy to transport and deposit.Because discharging platform employs above-mentioned expansion link 1, the height of adjustable telescopic rod 1 fast can either be carried out by the telescoping movement of external extension bar 11 and interior expansion link 12, the first screw mechanism 13 again by being located at interior expansion link 12 top realizes the height of fine setting expansion link 1, improves stability and the safety of discharging platform.Discharging platform of the present invention, can allow erection personnel in building, complete all installations erection, need not be pre-buried when diverse location is installed, expansion link can adjust required height fast and accurately, easy for installation, improve the installation effectiveness of platform simultaneously to greatest extent, simultaneously because the accuracy of expansion link adjustment can ensure that discharging platform is firmly fixed, discharging platform of the present invention is significantly improved than traditional discharging platform safety.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
