Abstract
This invention relates to a nut-like ramli including a bow, a front cover, an outer screw cover, a mind seat, a press rod, a screw rod, a base, a shell, a ratchet wheel, a column pin, gears, bearings, a mind and a connecting rod, in which, the ratchet wheel unit passes through the shell to fix the small gear joggled with the big one connected with the screw rod by a copper nut, which operates with rather little force and flexibly.
Description
Technical field
A kind of nut type puller of the present invention, what relate to is the hardware ﹠ tools technical field, specifically a kind of interference fit is a kind of instrument of part dismounting usefulness in addition.
Background technology
All in the market draw horse,, have traditional screw to draw horse and fluid pressure type to draw horse by its classification, fluid pressure type draws horse to be divided into split type two kinds of hydraulic pressure integral type and hydraulic pressure again, it is firmly big that screw draws horse to exist operation, instability, and pulling force is little, simultaneously, because fluctuation of service causes vibration easily, the warp-wise power of generation makes the slippage of transporting persons or goods by cart be drawn workpiece, the industrial accident that causes happens occasionally; Fluid pressure type draws horse, though the light advantage of tool operation, its volume is big relatively, owing to reasons such as leakage of oils, is not suitable for especially closing use at the field boundary that requirement of explosion proof is arranged, and has directly placed restrictions on the expansion of its range of application.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, design a kind of compact conformation, be suitable for different field boundarys and close the nut type puller of use.Its technology be achieved in that comprise top, protecgulum, external thread sleeve, the seat of transporting persons or goods by cart, press hand rod, screw rod, base, housing, ratchet mechanism, garden pin, gear, bearing, transport persons or goods by cart, the structure of connecting rod, it is characterized in that: ratchet mechanism passes housing by overlapping fixedly pinion, pinion and gear wheel engagement, gear wheel is connected with screw rod by copper nut, between module 2.5～6mm.The positive effect of implementing after this technology is: both having overcome screw, to draw horse to exist operation firmly big, unstable, pulling force is little, simultaneously, because fluctuation of service, cause vibration easily, the warp-wise power that produces makes the slippage of transporting persons or goods by cart be drawn the defective of workpiece, it is big relatively to have overcome its volume again, owing to reasons such as leakage of oils, be not suitable for especially closing use at the field boundary that requirement of explosion proof is arranged, directly placed restrictions on the defective of the expansion of its range of application, owing to adopted ratchet mechanism, operation is firmly less relatively, flexible operation, be the renewal product of a kind of valency in both.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of the embodiment of the invention;
Wherein, transport persons or goods by cart seat, 5-of 1-top, 2-protecgulum, 3-external thread sleeve, 4-presses that hand rod, 6-screw rod, 7-base, 8-housing, 9-ratchet mechanism, 10-garden pin, 11-copper nut, 12-large bevel gear, 13-cone pinion, 14-bearing, 15-cover, 16-connecting rod, 17-are transported persons or goods by cart, the 18-dust cover;
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
See accompanying drawing 1, ratchet mechanism (9) passes housing (8) by overlapping (15) fixedly pinion (13), pinion (13) and gear wheel (12) engagement, copper nut (11) is fixed in the gear wheel (12) and active connection of screw rod (6), screw rod (6) front end is used the guide-localization hole of passing protecgulum (2), the top is fixed with top (1), fixedly connected with external thread sleeve (3) in protecgulum (2) outer end, external thread sleeve (3) is fixedlyed connected with base (7), housing (8) is fixedlyed connected with base (7), be provided with bearing (14) between housing (8) and the gear wheel (12), the seat (4) of transporting persons or goods by cart is threaded with external thread sleeve (3), and can pass through the threaded adjusting position, transport persons or goods by cart (17) by and pin, connecting rod (16) with transport persons or goods by cart that (4) are active is connected for seat, housing (8) is fixing with base (7), dust cover (18) covers housing (8), and garden pin (10) is gear wheel (12) and copper nut (11) fixedly.
See accompanying drawing 1, example; When needs dismounting belt pulley, the seat (4) 3 transport persons or goods by cart (17) of transporting persons or goods by cart hooks belt pulley, pressing hand rod (5) rotates, drive the unidirectional rotation of ratchet mechanism (9), drive pinion (13) with its unidirectional rotation, drive with gear wheel (12) drive of its engagement and can't rotate by axially movable copper nut (11), the copper nut of rotation (11) is lead-screw (6), top conflict Pulley shaft axially, so continuous propelling is withdrawed from until belt pulley.
Claims (3)
1. a kind of nut type puller of the present invention, the structure that comprises top (1), protecgulum (2), external thread sleeve (3), transports persons or goods by cart seat (4), presses hand rod (5), screw rod (6), base (7), housing (8), ratchet mechanism (9), garden pin (10), gear, bearing (14), transport persons or goods by cart (17), connecting rod (16), it is characterized in that: ratchet mechanism (9) passes housing (8) by overlapping (15) fixedly pinion (13), pinion (13) and gear wheel (14) engagement, gear wheel (14) is connected with screw rod (6) by copper nut (11).
2. according to the described a kind of nut type puller of claim 1, it is characterized in that: the modulus of described gear is between 2.5～6mm.
3. according to the described a kind of nut type puller of claim 1, it is characterized in that: described gear can be bevel gear, garden stud wheel, worm gear, worm screw.
