Abstract
The utility model discloses an adjustable anti-drop puller. A threaded hole penetrating through a jaw disc is machined between the upper surface and the lower surface of the jaw disc, locating holes perpendicular to the threaded hole are further symmetrically and respectively formed in the positions, on two sides of the threaded hole, of the jaw disc in a machining mode, a threaded ejector rod is assembled in the threaded hole, pulling jaws and the jaw disc are assembled through locating shafts and the locating holes in the jaw disc, one ends of adjusting connecting rods are assembled with the locating holes, closest to the threaded hole, in the jaw disc through locating pins, adjusting grooves are formed in the adjusting connecting rods in a machining mode, fastening screws penetrate through the adjusting grooves to assemble the adjusting connecting rods with the pulling jaws, and an adjustable triangular stable structure is formed among the jaw disc, each pulling jaw and each adjusting connecting rod. The adjustable anti-drop puller is simple in structure and convenient to operate, rough adjustment, fine adjustment and locking can be respectively carried out on a detachable range through the locating holes in the jaw disc and the adjusting grooves in the adjusting connecting rods, and therefore an adjustable function of the anti-drop puller is achieved, magnets are arranged on the pulling jaws, and two structures act together to prevent the pulling jaws from dropping.
Description
Technical field
The utility model relates to a kind of extracting tool, is specifically related to a kind of adjustable anticreep and draws horse.
Background technology
Draw horse to be commonly used to dismantle axles such as bearing, gear, belt pulley and tighten firmware, the adjustable range of the existing common detachable diameter that draws horse is generally less, and versatility is not enough, can not dismantle multiple part; In addition, in the course of the work, because the self gravitation of pulling claw; or the unreasonable discontinuity that causes is installed, or firmly excessive, the situation that pulling claw comes off automatically appears through regular meeting; this can bring great inconvenience to dismantlement work, seriously reduces operating efficiency, influences the progress of work.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is, provides a kind of rational in infrastructure, and adjustable anticreep easy and simple to handle draws horse.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of adjustable anticreep draws horse, comprise the pawl dish, pulling claw, regulate connecting rod, threaded mandrel and trip bolt, wherein, between the upper surface of pawl dish and lower surface, be processed with the screwed hole that connects the pawl dish, also be symmetrily processed with the locating hole vertical with screwed hole on the pawl dish of screwed hole both sides respectively, threaded mandrel is assemblied in the screwed hole, assemble by the locating hole on locating shaft and the pawl dish between pulling claw and the pawl dish, an end of regulating connecting rod assembles by the locating hole of the most close screwed hole on alignment pin and the pawl dish, regulate on the connecting rod and be processed with regulating tank, trip bolt passes that regulating tank will be regulated connecting rod and pulling claw is assembled together, the pawl dish, form an adjustable triangle rock-steady structure between pulling claw and the adjusting connecting rod.
The utility model also has following technical characterstic:
Locating hole on the described pawl dish is at least four.
Be processed with the outer-hexagonal bolt head on the described threaded mandrel, also be processed with on the outer-hexagonal bolt head for the through hole that lever is installed.
Described pulling claw be disassembled the embedded magnet that is equipped with on the contacted end face of part.
The utility model is simple in structure, easy to operate, can carry out thick bar, fine setting and locking to the dismounting scope respectively by the regulating tank on the locating hole on the pawl dish and the adjusting connecting rod, but thereby realize the regulatory function that anticreep draws horse, at pulling claw magnet is installed, two kinds of structure actings in conjunction prevent that pulling claw from coming off.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
The implication of each label is among the figure: 1-through hole, 2-outer-hexagonal bolt head, 3-threaded mandrel, 4-alignment pin, 5-locating hole, the 6-pulling claw, the 7-regulating tank, the 8-trip bolt, 9-magnet, 10-is disassembled axle, 11-is disassembled part, and 12-regulates connecting rod, 13-pawl dish, 14-screwed hole.
Below in conjunction with drawings and Examples particular content of the present utility model is done explanation in further detail.
The specific embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as shown in Figure 1, a kind of adjustable anticreep draws horse, comprise pawl dish 13, pulling claw 6, regulate connecting rod 12, threaded mandrel 3 and trip bolt 8, wherein, between the upper surface of pawl dish 13 and lower surface, be processed with the screwed hole 14 that connects pawl dish 13, also be symmetrily processed with the locating hole 5 vertical with screwed hole 14 on the pawl dish 13 of screwed hole 14 both sides respectively, threaded mandrel 3 is assemblied in the screwed hole 14, assemble by the locating hole 5 on locating shaft 4 and the pawl dish 13 between pulling claw 6 and the pawl dish 13, regulate an end of connecting rod 12 by locating hole 5 assemblings of the most close screwed hole 14 on alignment pin 4 and the pawl dish 13, regulate on the connecting rod 12 and be processed with regulating tank 7, trip bolt 8 passes regulating tank 7 and will regulate connecting rod 12 and be assembled together pawl dish 13 with pulling claw 6, form an adjustable triangle rock-steady structure between pulling claw 6 and the adjusting connecting rod 12.
Locating hole 5 on the pawl dish 13 is at least four, is used for regulating the detachable radius of pulling claw 6.
Be processed with outer-hexagonal bolt head 2 on the threaded mandrel 3, also be processed with on the outer-hexagonal bolt head 2 for the through hole 1 that lever is installed, be used for installing activation lever.
