Abstract
The utility model discloses an adjustable hook wrench, and the utility model is composed of a hook head, a bow arm, a hand lever and an adjusting mechanism. Two guiders are arranged on the utility model, a threaded rod penetrates through the two guiders and is in threaded connection with a regulating nut arranged between the two guiders, the regulating nut is rotated to cause the threaded rod to move forwards and backwards in the two guiders, and space between the contact tip of the threaded rod and the hook head is changed. The adjustable hook wrench can be universal to the assembly and the disassembly of a circular nut ranging from M10 to M20 if the adjustable hook wrench is designed to four model numbers; the specifications of the Hook wrenches are reduced, tools and materials are saved, the utility model is convenient in use, and the utility model improves efficiency in disassembling assembling equipment.
Description
The utility model relates to a kind of Hook wrench, particularly the Hook wrench of being made up of eave tile, bow arm and handle with what folding dress round nut.
Using the most general securing member in mechanical industry is that the round nut of six square nuts and round nut two big classes, standard has tens of kinds of specifications approximately from M10-M200, and the installation and demolition instrument of round nut has only traditional fixed hook spanner, it is made up of eave tile, bow arm and handle, and every kind of fixed hook spanner can only be rolled over the close round nut of dress specification, so all will be equipped with the Hook wrench of plurality of specifications usually, join complete being difficult for, use inconvenience.
The purpose of this utility model provides the bigger adjustable Hook wrench of a kind of scope of application.
For achieving the above object, the solution that the utility model adopts is: round nut is divided into four intervals from M10-M200, be designed to the adjustable Hook wrench of four specifications and models, the design principle of every kind of model is identical with structure, it is made up of eave tile, bow arm and handle, it is characterized in that: the intersection at bow arm and handle is provided with two guiders, in two guiders screw rod is housed, and between two guiders the screw rod adjusting nut is housed.For making adjustable Hook wrench guarantee that in the maximal regulated scope force, fulcrum distribute rationally, its eave tile 1 center line by the round hearts in the bow arm 8 and with the bow arm in the circle center line become angle α 1, the center line of screw rod 5 intersects angle α 2 with bow arm 8 interior circle center extended lines, and the vertical distance of the round heart is H in the center line of screw rod 5 and the bow arm 8.
Owing to adopted technique scheme, the round nut folding dress that only needs the adjustable Hook wrench of four specifications can satisfy the dozens of specification uses, reduced and colluded wrench specification quantity, save tool materials, and the fulcrum of adjustable Hook wrench, force reasonable in design, easy to use, do not damage round nut, improve folding and pretend industry efficient.
Below in conjunction with drawings and Examples the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the adjustable Hook wrench structure of a utility model front view.
Fig. 2 is that the adjustable Hook wrench screw rod of Fig. 1 moves dynamic figure.
Adjustable Hook wrench shown in Figure 1, by eave tile, the bow arm, composition such as handle and adjusting screw, two guiders are fixed on bow arm and handle intersection, in two guiders screw rod 5 is housed, adjusting nut 3 is arranged between guider 2 and the guider 4 and be threaded with the screw rod 5 that passes two guiders, rotation adjusting nut 3 makes screw rod 5 along moving forward and backward in guider 2 and the guider 4, change the distance between screw rod contact 9 and the eave tile 1, to be suitable for the round nut dismounting of what different-diameter, guarantee the force for cooperating in round nut maximum gauge and the minimum diameter scope, fulcrum distributes rationally, its eave tile 1 center line is 0 °-45 ° by the round heart in the bow arm 8 and with bending arm 8 interior circle center line angle α 1, it is 0 °-30 ° that the center line of screw rod 5 intersects angle α 2 with bow arm 8 interior circle center extended lines, and the center line of screw rod 5 is 100mm to the maximum with the vertical range H of the bow arm 8 interior round hearts.
Fig. 2 is that dynamically scheme the screw rod shift position of adjustable Hook wrench shown in Figure 1.By shown in Figure 2, rotation adjustable nut 3, screw rod 5 will move forward and backward along guider, its maximum magnitude that moves promptly is that the round nut minimum diameter that is suitable for is to the maximum gauge scope, remain at best position of the fulcrum at this adjustable range inner screw contact 9, it is the optimum position that is guaranteed adjustable extent inner-support, force by the α among Fig. 11, α 2 and H value parameter.
Present embodiment is divided into four intervals with the round nut of tens of kinds of specifications between the M10-M200, the adjustable Hook wrench of each interval corresponding a kind of specification, the maximum gauge of each interval round nut and minimum diameter are exactly the maximal regulated scope of the adjustable Hook wrench of this specification, the adjustable Hook wrench of such four kinds of specifications can be used as the general utility tool of tens of kinds of specification round nut folding dresses, save tool materials, easy to use, be suitable for all kinds of machine-building of what, installation and maintenance department.
