Description

Technical Field

[0001] The present invention is a tool for disassembling the back cover of a product, which can achieve the disassembly of the back cover of the product. Background Art

[0002] In aerospace products, the back cover of a certain type of product needs to be disassembled multiple times. Since the torsion piece needs to be installed first during the assembly of the back cover and then inserted into the rear end of the product, the torsional force of the torsion piece makes the back cover closely attached to the product, and the frictional force during the disassembly of the back cover is relatively large. Currently, the disassembly of the product back cover generally uses a screwdriver to insert into the disassembly groove of the product back cover, and the back cover is separated from the product by methods such as "prying", "twisting", and "knocking". This method mainly has the following two problems:

[0003] (1) When using a screwdriver for disassembly, it is easy to make the product rotate, and the surface of the product is easily scratched by the screwdriver when the operation is improper.

[0004] (2) Certain skills and experience are required during the operation, and the work efficiency is low. Summary of the Invention

[0005] The purpose of the present invention is to provide a tool for disassembling the back cover of a product, which can achieve the rapid disassembly of the back cover of the product, improve the work efficiency and avoid scratching the product.

The inclined surface 211 on the hook head 21 contacts and is stressed by the back cover 12, and the hook claws 2 open to both sides. After the two hook heads 21 enter the disassembly slots 121 of the product back cover 12, the hook claws 2 are subjected to the inward torsion force of the torsion springs 3, and the two hook heads 21 are clamped in the two disassembly slots 121 of the product back cover 12; pinch the two handles 8, and the two handles 8 drive the connecting rod I 6 and the connecting rod II 7 to move towards each other and slide forward around the pin 5. The connecting rod I 6 and the connecting rod II 7 push the push rod 4 to slide forward. After the cylindrical head 41 of the push rod 4 contacts the torsion piece of the product, it will cause the hook claws 2 to drive the product back cover 12 to move backward relative to the product torsion piece. Continue to pinch the two handles 8 to complete the disassembly of the product back cover 12.

The specific device solution is as follows: A tool for disassembling the product rear cover includes a cover plate, a hook claw, a torsion spring, an ejector rod, a pin, a connecting rod I, a connecting rod II, a handle, a compression spring, a bolt and a nut.

[0033] The cover plate is in the shape of a stepped plate, with a quantity of 2 pieces. The inner surface of the lower step has a rectangular keyway and a through-hole, which are respectively used for assembling a pin and a bolt to pass through and connect the handle. The middle of the inner surface of the upper step has a semi-cylindrical groove for assembling the ejector rod. The two ends of the inner surface of the upper step have an open groove and a through-hole, which are respectively used for assembling a torsion spring and a bolt to pass through and connect the torsion spring and the hook claw. There is a boss on the side of the upper step for restricting the position of the hook claw.

[0034] The hook claw is in an L-shaped hook structure, with a quantity of 2 pieces. The rear end of the long arm has an open groove for assembling the cover plate. There are through-holes in the two forks at the rear end of the long arm for a bolt to pass through and connect the torsion spring and the cover plate. There is an inclined surface on the short arm.

[0035] The ejector rod is in the shape of a stepped shaft. The head of the stepped shaft is a cylinder. There are round through-holes in the two forks at the tail of the stepped shaft for a pin to pass through and connect the connecting rod Ⅰ and the connecting rod Ⅱ.

[0036] The pin is in the structure of a stepped cylinder. The small-diameter end of the cylinder is used to connect the ejector rod, the connecting rod Ⅰ and the connecting rod Ⅱ.

[0037] The connecting rod Ⅰ is in a fork-shaped structure. There is a small cylinder at the rear end of the fork for passing through the mounting hole of the handle to connect the handle. There are round through-holes in the two forks at the front end of the fork for a pin to pass through and connect the ejector rod and the connecting rod Ⅱ.

[0038] The connecting rod Ⅱ is in a rod-shaped structure. There is a small cylinder at the rear end of the rod for passing through the mounting hole of the handle to connect the handle. There is a round through-hole at the front end of the rod for a pin to pass through and connect the ejector rod and the connecting rod Ⅰ.

[0039] The handle is in an inclined L-shaped rod structure, with a quantity of 2 pieces. There is a convex block in the middle of the long arm for installing a compression spring. There is a round through-hole at the head of the short arm for assembling the connecting rod Ⅰ and the connecting rod Ⅱ.

[0040] Specifically, first insert the pin into the through-holes of the ejector rod, the connecting rod Ⅰ and the connecting rod Ⅱ to connect the three. Connect the front through-holes of the two handles with the small cylinders of the connecting rod Ⅰ and the connecting rod Ⅱ. Put the cylindrical head of the ejector rod into the semi-cylindrical groove of the cover plate. Put the pin into the keyway of the cover plate. Connect the cover plate and the handle through bolts and nuts. The handle can rotate around the rotating bolt. Place the torsion spring and the hook claw on the cover plate, and connect the hook claw, the torsion spring and the cover plate frame through bolts and nuts. The hook claw can rotate around the bolt. Install the compression spring on the convex block of the handle. When in use, first push the hook claw towards the disassembly groove of the product rear cover. The inclined surface on the hook head contacts and is stressed by the rear cover, and the hook claw opens to both sides. After the hook head enters the disassembly groove of the product rear cover, the hook claw is clamped in the disassembly groove of the product rear cover by the inward torsion force of the torsion spring. Squeeze the handle, and the handle drives the connecting rod Ⅰ and the connecting rod Ⅱ to move towards each other and slide forward around the pin, thereby pushing the ejector rod to slide forward. After the cylindrical head of the ejector rod contacts the torsion piece of the product, it will cause the hook claw to drive the product rear cover to move backward relative to the product torsion piece. Continue to squeeze the handle to complete the disassembly of the product rear cover.
