Description

Technical Field

[0001] The invention relates to a handleless mobile phone carrying equipment extraction device. Background Art

[0002] With the development of sensors, data processing and machine learning technologies, new commercial aircraft have introduced a large number of electronic and electrical equipment, and the number of signal transmissions of airborne equipment has increased massively. Traditional airborne equipment is connected by circular connectors, but the density of circular connectors is low, and it is increasingly difficult to meet the growing usage requirements. To solve the above problems, rectangular connectors have been introduced for airborne equipment. The pin density of rectangular connectors has been greatly improved compared to circular connectors, but the dense pins form a large plug-in and pull-out force. Many airborne devices are affected by factors such as human-machine efficiency and weight, and it is impossible to set a gripping interface such as a handle. To unplug such devices, usually you can only shake them slowly until the connector loosens. This unplugging method is very time-consuming and laborious. At the same time, this unplugging method is prone to deformation of the connector pins or even damage to the connector due to uneven force on the connector, which damages the function of the device. And when the device connector is disconnected, the device has no protective measures and is prone to accidental drop, causing abnormal damage to the device. Therefore, it is urgent to develop a handleless mobile phone device unplugging device to solve the above-mentioned current problems. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned problems existing in the prior art and to provide a handleless mobile phone equipment extraction device. The connection with the equipment is reliable and simple, the unlocking is convenient, the operation process will not damage the surface of the equipment, and it can be used as a temporary transfer device for the equipment to prevent the equipment from accidentally falling during disassembly and transportation. Only two extraction bolts need to be added to the equipment end, which has little effect on the overall weight of the equipment. For many devices installed on the airborne equipment rack, the handle and other extraction devices can be eliminated. Only two extraction bolts need to be set, and the same extraction device can be reused to reduce the overall weight.

[0004] The present invention is a device for extracting a mobile phone device without a handle, which includes a handle and a base.

[0012] The present invention is described in detail below with reference to the accompanying drawings and embodiments. Implementation

[0013] The figure shows a handleless mobile phone device extraction device, which includes a handle 1 and a base 2, and is characterized in that: a fixed hook 3 is provided at the bottom of the end of the handle, a locking pin hole 4 is provided at the front end of the handle, a locking pin 5 is installed in the locking pin hole, a free hook limiting surface 6 is provided on the front end surface of the handle, a handle fixed support end 7 is provided at the end of the base, and the handle fixed support end is connected to the end of the handle by a rotating shaft 23, a handle position locking end 8 is provided at the front end of the base, and the front and rear ends of the base are connected by a middle base body 9, and the free hook 22 is connected to the handle position locking end 8 by a rotating shaft 10. The fixed hook 3 provided at the bottom of the handle end has a U-shaped opening to the outside, and the fixed hook is an inner concave surface. The free hook limit surface 6 provided on the front end surface of the handle is composed of an upper plane 11 and a rear arc front 12. The free hook limit surface corresponds to the rotation positioning block 13 of the free hook installed below the handle position locking end. The upper end surface of the rotation positioning block of the free hook is composed of a plane 14 and an arc surface 15 at the rear end. The free hook is provided with a U-shaped opening toward the outside, and the free hook is an inner concave surface. A waist-shaped long hole 16 is provided in the middle of the locking pin hole provided at the front end of the handle, and a radial locking limit pin 17 is provided in the middle of the locking pin. The limit pin is located in the waist-shaped long hole. A spring 18 is provided below the bottom of the locking pin installed in the locking pin hole. An inward semi-open waist-shaped groove 19 is provided at the upper part of the handle position locking end of the base, and the locking limit pin 17 corresponds to the semi-open waist-shaped groove 19. An anti-wear pad installation groove 20 is provided at the bottom of the middle base body of the base, and an anti-wear pad 21 made of polytetrafluoroethylene is installed in the anti-wear pad installation groove. The center distance between the fixed hook end and the free hook of the handle is equal to or slightly smaller than the distance between the extraction bolts arranged on the handleless mobile phone device.

[0014] like Figure 5When in use, in order to make the fixed hook and the free hook of the handle clamp the extraction bolt 30 at the same time, press the locking pin, open the handle, and make the fixed hook of the handle rotate along the pin shaft of the fixed end of the base handle. When the handle is opened to the maximum position, the fixed hook can be recovered to the minimum position; at the same time, the free hook fixed at the locking end of the base position can also be rotated along the pin shaft and recovered to the minimum position; after the fixed hook and the free hook of the handle are recovered in place, their maximum spacing is smaller than the extraction bolt spacing, and the extraction device can be easily placed between the two extraction bolts of the equipment.

[0015] Place the extraction device approximately in the middle of the two extraction bolts of the equipment. The locking pin should be located in a direction that is convenient for the thumb to operate. At this time, only the anti-wear pad on the bottom of the base is in contact with the equipment. Slowly lower the handle and align the fixed hook end of the handle with the neck of the extraction bolt until the handle begins to contact the base. Rotate the free hook so that its U-shaped opening is aligned with the neck of the extraction bolt on the other side. Continue to rotate the handle so that the limit pin slides into the semi-open waist-shaped groove opened at the upper part of the handle position locking end of the base. At this time, the fixed hook of the handle rotates to be fully connected, and the free hook is also fully connected under the action of the guide surface and the limit plane of the handle. The limit pin on the locking pin enters the semi-open waist-shaped groove opened at the upper part of the handle position locking end of the base, which means that the extraction device is locked.

[0016] The handle and the base form a natural space after the connection is completed, and the space allows one hand to hold the extraction device. By holding the extraction device in this position, the device 31 can be extracted.

[0017] Press the locking pin to unlock the handle; pull the handle, the fixed hook of the handle rotates and retracts, and at the same time, the free hook of the handle separates at the limit surface, and the free hook is unlocked; continue to lift the extraction device to separate the extraction device from the equipment, thereby realizing one-button unlocking of the extraction device.

[0018] Preferably, the extraction device is arranged on a structure on the back side of the rectangular connector in the extraction direction, and the extraction force is not transmitted to the connector through a turn, and no accessory bending moment is formed, so the extraction operation is simpler.

[0019] like Figure 6 A method for unplugging a mobile phone-mounted device without a handle, using two of the above-mentioned onboard device unplugging devices. The method comprises the following steps: The hooks on both sides of each airborne equipment extraction device are moved outward and expanded, connected to the extraction bolts on the airborne equipment, and lock them.

[0020] The two onboard equipment extraction devices are parallel to each other and are located on both sides of the equipment.

[0021] The two extraction devices and the equipment form a stable connection through four extraction bolts, which evenly transmit the extraction force to the connector at the rear of the equipment and enable the operator to grasp the progress and status of the equipment extraction through the feedback of the reaction force.

[0022] Hold the two pull-out devices with both hands and pull out the device.

[0023] The extraction device and the equipment are reliably connected, and the equipment is allowed to be turned over after extraction, and can be used as a handle to temporarily carry the equipment. The extraction, clamping and related carrying work of the equipment can be realized by the above method.

[0024] The retracted spacing of the two side hooks of the extraction device of the present invention is smaller than the spacing of the extraction bolts, and the two side hooks can be respectively inserted from below to clamp the extraction bolts; the position locking pin can be pressed with only one finger, and the operation is simple.

[0025] The above only expresses the implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
