Detailed description of the invention
The present invention is as shown in figs. 1-12, including barred body 1, connect seat 2 and the hook 3 of pair of opposing, described connection seat 2 is fixedly connected on one end of barred body 1, the top of described connection seat 2 is equipped with central shaft 20, link up with 3 described in a pair and be divided into fixed hook 31 and Removable hook 32, the bottom of described fixed hook 31 is socketed on central shaft 20, and the bottom of described Removable hook 32 is fixedly linked with central shaft 20；I.e. fixed hook can do relative rotary motion with central shaft, and Removable hook then keeps synchronous rotary motion with central shaft；
Described drop bar is additionally provided with driving assembly 4 and shifter assemblies 5；
Described driving assembly 4 includes drive rod 41, horizontal helical gear 42, a pair vertical helical gear 43 and a pair driving ring 44, described drive rod 41 is arranged in barred body 1, and drive rod 41 top extend out to connect in seat 2, described horizontal helical gear 42 is fixedly connected on the top of drive rod 41, and with drive rod 41 concentric, described in a pair, vertical helical gear 43 is respectively fixedly connected with in the bottom of a pair hook 3, described vertical helical gear 43 and central shaft 20 concentric, and set up separately in the both sides of horizontal helical gear 42, described in two, vertical helical gear 43 is all suitable with horizontal helical gear 42, and two the spacing of vertical helical gear 43 more than the external diameter of horizontal helical gear 42；Driving ring 44 be fixedly connected with on central shaft 20 and set up separately in the both sides of fixed hook 31 described in a pair, two drive the spacing of rings 44 bottom more than the fixed hook 31 axial length along central shaft 20 and the axial length sum along central shaft 20 of vertical helical gear 43；Described fixed hook 31 is provided with some fixing tapered ends 310 away from the bottom of a side end face of Removable hook 32, and described connection seat 2 offers some and fixing tapered end 310 adaptation locked groove on the end face of fixing tapered end；As shown in Fig. 3-12, first, after by the position of central shaft Fig. 8,9,10 can being divided into, in, front third gear；
Before using, first central shaft can be pushed rear shelves and make to be positioned at the vertical helical gear (hereinafter referred to as helical gear two) that fixed hook is fixedly connected on fixed hook bottom away from driving ring (hereinafter referred to as the driving ring two) compressing of the side of Removable hook and engage with the holding of horizontal helical gear；
So, as shown in Figure 8, under rear shelves state, operating personnel can rotate drive rod at far-end, and by the transmission between horizontal helical gear and helical gear two, be adjusted the angle of fixed hook according to the actual requirements；I.e. achieve the purpose to " angle between hook and barred body conveniently regulates "；
After treating angular adjustment, promote central shaft, it is allowed to be transferred to front shelves state by rear shelves state, now, fixed hook will be directed away from the side translation of Removable hook under the compressing at the driving ring (hereinafter referred to as driving ring one) between fixed hook and Removable hook, thus finally make some fixing tapered ends be pushed in locked groove to guarantee that fixed hook and the angle of barred body keep constant, i.e. efficiently accomplish the purpose of " easily the angle between hook and barred body is adjusted and is fixed "；Meanwhile, the vertical helical gear (hereinafter referred to as helical gear one) being fixedly connected on Removable hook also by the motion with central shaft gradually with horizontal helical gear to engaging；
So, as shown in Figure 10, under front shelves state, fixed hook can be overlapped on electric wire by operating personnel, and constantly rotates drive rod at far-end so that the most sagging Removable hook is flipped up, until clamping electric wire together with fixed hook；I.e. efficiently accomplish the purpose of " stability after drop bar mounting and between electric wire is high ", and effectively prevent the problem of " it is big that electric wire enters hook difficulty " in prior art；
And after drop bar uses, only need that central shaft has front shelves state push middle-grade state, now, as shown in figure 11, helical gear one will depart from horizontal helical gear, so that Removable hook is the most sagging under gravity, i.e. completes the hook unblock to electric wire by one-touch simple operations, thus effectively prevent the problem of " electric wire pull-out hook difficulty is big " in prior art；
Finally, when reusing, central shaft is pushed again in rear shelves, can again the angle of fixed hook be adjusted；
Described shifter assemblies 5 includes power frame 51, power rail 52 and centre mount 53, described power frame 51 includes a pair power plate 511 and fixes bar 512 for a pair, power plate 511 described in two is fitted on the both sides end face of central shaft 20 respectively, and fix bar 512 be fixedly linked by two, the top of described power rail 52 is hinged in the middle part of fixing bar 512, described centre mount 53 includes that the pedestal 531 of C font and a pair top take turns 532, described pedestal 531 is socketed and is fixedly connected on the top of barred body 1, described in two, top wheel 532 is hingedly connected in the two ends of pedestal 531, power rail 52 top is stuck between two top wheels 532.So, operating personnel can on the position of operation drive rod (far-end) complete by push-and-pull power rail central shaft before, during and after efficiently switching between three gears, effectively optimize the type of drive of central shaft, and use lever principle to effectively reduce the labour intensity of operating personnel.
Described drive rod 41 extend out to outer one of barred body 1 and brings out and be also associated with rotary handle 6, described rotary handle 6 is socketed in the end of drive rod 41, it is fixedly connected with slide key 410 on the termination of described drive rod 41, and length adaptive with slide key 410 sliding tray 60 more than slide key is offered on the inwall of described rotary handle 6, it is fixedly connected with some latches 61 on the end face of described rotary handle 6, the bottom surface of described barred body offers some for housing described lock bolt groove.So, operating personnel can be very convenient by operation rotary handle to complete the driving to drive rod rotary motion.Additionally, when central shaft is in front shelves, after operating personnel's turn rotary handle drives Removable hook to be rotated up locking electric wire, can on push away rotary handle so that some latches snap in pin-and-hole, to complete " locking " to Removable hook.
Described connection seat 2 is fixedly connected with vertical cushion block 21 on the end face of fixing tapered end 310 bottom, and some described locked grooves are all opened on vertical cushion block 21, offers the slide opening for accommodating driving ring 44 in the middle part of described vertical cushion block 21；
The bottom surface of described horizontal helical gear 42 is additionally provided with horizontal cushion block 22 with being connected between seat, and described horizontal cushion block 22 is socketed described drive rod 41.So, vertical cushion block and horizontal cushion block by setting up effectively optimize product structure so that drop bar is the most more stable, attractive in appearance, symmetry is more preferable.
Described power plate 511 top is also fixedly connected with horizontal slide plate, and described horizontal slide plate fits in the top connecting seat 2.So that the driving of " gearshift " action of central shaft is the most smooth, stability when being effectively improved device action and the labour intensity of operating personnel.
The middle part of the outer wall of described barred body 1 is also fixedly connected with damping draw-in groove 10.Make operating personnel can find middle-grade accurate location the most intuitively, easily when operation, significantly reduce operation easier, improve operating efficiency.
Some fixing tapered ends 310 are distributed on same circumference for the center of circle with the axle center of central shaft and fit between adjacent fixing tapered end 310.So, as shown in fig. 6-7, after the angle regulation between fixed hook and barred body, what some fixing tapered ends can be more smoothly pushes in locked groove.
