Description
Technical Field
[0001] The utility model relates to the field of unlocking locking rudder wings, in particular to a portable unlocking tool for unlocking complex rudder wings. Background Art
[0002] The folding rudder wing servo is developed under the condition that tactical missiles seek miniaturized launch devices to make launch, transportation and storage simple and convenient. For missiles, it reduces the lateral dimension, is convenient for storage, transportation and launch in boxes (cylinders), saves the storage and transportation space of missiles, increases the storage and transportation capacity of storage and transportation devices, and improves the combat ability of weapon systems.
[0003] During the use and transportation of the servo, in order to prevent damage such as scratches and bending of the rudder wing of the servo during transportation, as well as for loading and using, it is usually necessary to fold the rudder wing of the servo. However, before folding the rudder wing, the rudder wing needs to be unlocked, and at this time, an unlocking tool is required to complete the operation.
[0004] However, the patents in the prior art have the following several disadvantages:
[0005] (1) Most of the folding rudder wings belong to the two-hole unlocking type. The existing ordinary unlocking tools require two people to unlock one hole each. When multiple people operate, the force is uneven and the direction is inaccurate, resulting in problems such as unlocking failure, which is very troublesome to use on products. Content of the Utility Model
[0006] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a portable unlocking tool that can be operated by a single person and unlocks with two needles simultaneously.
[0007] To solve the above problems, the technical solution of the utility model is: a portable unlocking tool, including: a servo, a rudder wing and an unlocking component;
[0008] Both sides of the servo are fixedly connected with support plates. One end inside of the support plate is fixedly connected with a fixed shaft. The rudder wing is rotationally connected to the outside of the fixed shaft through a connecting ring. A torsion spring is sleeved on the outside of the fixed shaft. One end of the torsion spring is fixedly connected with the fixed shaft, and the other end of the torsion spring is fixedly connected with the connecting ring of the rudder wing. The rudder wing is supported and pushed by the torsion spring to be locked in the unlocked state. A straight insertion hole is opened on one side of the connecting ring of the rudder wing, and an inclined insertion hole is opened on the other side of the connecting ring of the rudder wing. The inclined insertion hole is communicated with the straight insertion hole. A sliding groove is opened on one end inside of the support plate. A pin is slidably connected inside the sliding groove. A spring is fixedly connected between the pin and the bottom end of the sliding groove. The spring pushes the pin to insert into the straight insertion hole of the connecting ring of the rudder wing to lock the rudder wing. The unlocking component is arranged on one side of the rudder wing. The unlocking component is detachably installed. The unlocking component includes: a handle and steel wire needles. There are two steel wire needles in total, both of which are fixedly connected to one end of the handle. The steel wire needles can be inserted into the inclined insertion hole.
[0009] Further, the handle shape is modeled according to the shape of the rudder wing. The handle has a limiting step on its outer shape, which can better align with the unlocking direction and control the safe distance of the steel wire needle for unlocking. The handle is made of aluminum alloy material.
[0010] Further, the length of the steel wire needle is determined according to the unlocking requirements of the rudder wing. When the length of the steel wire needle is such that the limiting step coincides with the step of the rudder wing, the unlocking component just achieves the unlocking effect. When the rudder wing is toggled, the steel wire needle will not be broken. The material of the steel wire needle uses high-speed steel used in machining turning tools.
[0011] The advantages of the present utility model compared with the existing technology are as follows:
[0012] (1) The portable unlocking tool of the present utility model changes the original single-needle unlocking to double-needle unlocking and changes the original multi-person operation to single-person single-machine operation, which not only improves work efficiency but also saves most of the labor force. The handle has a limiting step that can not only maintain the unlocking direction but also limit the insertion length of the steel wire needle to prevent the steel wire needle from being twisted and broken during unlocking.

[0020] Embodiment 1:
[0021] As Figures 1 to 4 shown, a portable unlocking tool includes: an unlocking component. Both sides of the steering gear are fixedly connected with support plates. One end of the inner side of the support plate is fixedly connected with a fixed shaft. The steering vane is rotatably connected to the outside of the fixed shaft through a connecting ring. A torsion spring is sleeved on the outside of the fixed shaft. One end of the torsion spring is fixedly connected with the fixed shaft, and the other end of the torsion spring is fixedly connected with the connecting ring of the steering vane. When in the unlocking state, the steering vane is supported and pushed by the torsion spring to be locked. A straight insertion hole is provided on one side of the connecting ring of the steering vane, and an inclined insertion hole is provided on the other side of the connecting ring of the steering vane. The inclined insertion hole is communicated with the straight insertion hole. A chute is provided on the inner side of one end of the support plate. A pin is slidably connected to the inside of the chute. A spring is fixedly connected between the pin and the bottom end of the chute. The spring pushes the pin to insert into the straight insertion hole of the connecting ring of the steering vane to lock the steering vane. The unlocking component is arranged on one side of the steering vane and is detachably installed. The unlocking component includes: a handle and a wire pin. There are two wire pins in total, both of which are fixedly connected to one end of the handle. The wire pins can be inserted into the inclined insertion holes.
[0022] The shape of the handle is modeled according to the shape of the steering vane. The outer shape of the handle has a limiting step to better align the unlocking direction and control the safe distance of the wire pin for unlocking. The material of the handle is made of special aluminum alloy material.
[0023] The length of the wire pin is formulated according to the unlocking requirements of the steering vane. When the length of the wire pin is such that the limiting step coincides with the step of the steering vane, the unlocking component just achieves the unlocking effect. When the steering vane is turned, the wire pin will not be broken. The material of the wire pin uses high-speed steel used for machining turning tools.
[0024] In specific use, with the limiting step of the handle 11 facing the steering vane 4, the wire pin 12 is inserted into the inclined insertion hole 7 of the connecting ring of the steering vane 4. Hold the steering vane 4 by hand, press with the thumb contacting the stress surface of the handle 11. When the limiting step coincides with the step of the steering vane 4, turn the steering vane 4 by 90°. During the insertion of the wire pin 12, gradually push the pin 8 back into the chute of the support plate 2, so that the steering vane 4 can rotate around the fixed shaft 3. Then take out the unlocking component 10 to complete the unlocking. After unlocking, external forces (such as tape, strapping, sleeve, etc.) are needed to fix the steering vane 2 in the unlocked state. If the external force is removed, the steering vane 2 will be supported and pushed by the torsion spring 5 and automatically bounce back to the locked state.
[0025] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
