Description

Technical Field

[0001] The utility model relates to the technical field of rivets, in particular to a copper-iron rivet for a printer. Background Art

[0002] A rivet is a fastener used to connect two or more workpieces. It usually consists of a nail with a head and a hollow sleeve. The method of using a rivet is to insert one end of the nail into a pre-drilled workpiece, and then expand it together with the sleeve by applying pressure at the other end of the nail. During the expansion process, the tail of the nail will be sheared or bent to form a strong connection. The design of the nail head can prevent the rivet from slipping off the workpiece. Rivets are a reliable connection method used to connect two or more workpieces. By inserting the nail into a pre-drilled workpiece and applying pressure to expand it together with the sleeve to form a strong connection, rivets can withstand forces such as tension, shear and vibration to provide a stable connection. Rivet connections have high strength and rigidity and can withstand large loads, which makes rivets very useful in applications that require high strength and reliability, such as aviation, automobiles and machinery manufacturing. Rivet connections have high strength and rigidity and can withstand large loads, which makes rivets very useful in applications that require high strength and reliability, such as aviation, automobiles and machinery manufacturing. Compared with welding, rivet connection does not require additional subsequent treatment, such as heat treatment or coating, which saves time and cost and improves production efficiency. The "rivet" disclosed by the authorization announcement number "CN213870636U" has solved the problem that the single-drum blind rivets on the market currently lack locking measures for the broken end of the rivet mandrel and the rivet body during riveting, and the fastening of the rivet body is poor and the fixing strength is low. After further search, it was found that the authorization announcement number "CN213270628U The disclosed "anti-pulling rivet head loosening rivet" effectively solves the problem that the existing rivet head is easy to loosen during use through a specific technical structure setting. There is no locking device between the screw head and the rivet rod. If it is loose, it will affect the use of mechanical equipment. For this reason, we propose the problem of anti-pulling rivet head loosening rivet. However, in actual use, rivets with similar structures still have many defects, such as: general rivets are easy to loosen after long-term use, thereby affecting the stability of the rivets, and it is not convenient to disassemble the rivets. Therefore, it is necessary to design a copper-iron rivet for printers. Utility Model Content

[0003] The utility model aims to provide a copper-iron rivet for a printer to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a copper-iron rivet for a printer, comprising a nail cap, a nail core and an expansion block, the bottom of the nail cap is fixedly connected to the nail core, the bottom of the nail core is fixedly connected to the expansion block, a mounting hole is provided inside the nail core, a block is fixedly connected inside the mounting hole, the inside of the mounting hole is fixedly installed with a pressure rod through the block, and a fixing groove is provided inside the pressure rod outside the block.

[0005] When using rivets to fix the printer, first insert the nail core into the fixed hole reserved on the printer, then press the pressure rod into the mounting hole inside the nail core, and during the press installation, make the block move inside the slide groove. After the pressure rod is completely immersed in the mounting hole, use the rotating key to control the pressure rod to rotate through the pressing block, so that the block inside the nail core can enter the fixed groove. After the nail core rotates to a certain angle, remove the rotating key to vacate the mounting groove on the pressing block, and then reset the block through the spring inside the nail core. The card block is made to enter the interior of the installation groove, so that the mutual cooperation between the stop block and the card block can prevent the pressure rod from being separated from the installation hole inside the nail core when the printer is used, thereby causing the problem of rivet loosening to occur. When removing the rivet, the rotating key is inserted into the installation groove inside the pressing block, and the rotating key completely pushes the card block inside the nail cap into the nail core, and then the pressing block is rotated in the opposite direction by the rotating key, so that the pressing block drives the pressure rod to rotate inside the installation hole, so that the stop block enters the sliding groove inside the pressure rod, and then the pressing block is pulled out of the installation hole in the nail core together with the pressure rod. Because the material used for the expansion block has resilience, after the pressure rod is pulled out from the installation hole, the expansion block will automatically rebound, and then the rivet is removed from the printer as a whole, thereby achieving the purpose of facilitating the removal of the rivet.

[0006] Preferably, a slide groove is provided inside the pressure rod at the bottom of the fixing groove, and a pressing block is fixedly connected to the top of the pressure rod at the top of the nail cap. The slide groove can prevent the block from blocking the installation path of the pressure rod when the pressure rod is installed, and can allow the block to enter the inside of the fixing groove. The contact area of ​​the pressure rod can be increased by the pressing block, and the combination of the pressing block and the nail cap can beautify the overall appearance of the device.

[0007] Preferably, the pressing block is provided with an installation slot inside which a rotation key is fixedly installed. The installation slot allows the block to be combined with the pressing block, thereby preventing the pressing rod from rotating inside the nail core, and the pressing block can be controlled to rotate by the rotation key.

[0008] Preferably, a clamping block is movably connected inside the nail core at the bottom of the rotating key, and a spring is fixedly installed inside the nail cap at the bottom of the clamping block. The clamping block can prevent the pressing block from rotating after the pressing rod is installed in the installation hole, and the spring can assist the clamping block, and at the same time, when the pressing rod is disassembled, a thrust force can be generated on the pressing block to make the disassembly of the pressing rod more convenient.

[0009] Preferably, a pressure plate is fixedly connected to the bottom of the clamping block at the top of the spring, and a limited position cavity is provided inside the nail cap outside the spring. The pressure plate can increase the contact area between the clamping block and the spring, so that the clamping block can squeeze the spring, and the limited position cavity can provide an installation position for the spring and limit the movement trajectory of the pressure plate.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] Through the cooperation between the stopper and the internal sliding groove and the fixing groove of the pressure rod, when the rivet is used to fix the printer, the nail core is first inserted into the fixed hole reserved on the printer, and then the pressure rod is pressed into the mounting hole inside the nail core. During the press-fitting, the stopper is moved inside the sliding groove. After the pressure rod is completely immersed in the mounting hole, the pressure rod is controlled to rotate by the rotating key, so that the stopper inside the nail core can enter the interior of the fixing groove. After the nail core is rotated to a certain angle, the mounting groove on the pressing block is vacated by removing the rotating key, and then the card block inside the nail core is reset to allow the card block to enter the interior of the mounting groove, so that the cooperation between the stopper and the card block can prevent the pressure rod from being separated from the mounting hole inside the nail core when the printer is used, thereby causing the problem of rivet loosening. The contact area between the card block and the spring can be increased by the pressure plate, so that the card block can squeeze the spring. The limiting cavity can provide an installation position for the spring and limit the movement trajectory of the pressure plate.

[0012] Through the cooperation between the nail core and the pressure rod, when the rivet is disassembled, the rotating key is inserted into the installation groove inside the pressing block, and the rotating key completely pushes the block inside the nail cap into the nail core, and then the pressing block is rotated in the opposite direction by the rotating key, so that the pressing block drives the pressure rod to rotate inside the installation hole, so that the blocking block enters the sliding groove in the pressure rod, and then the pressing block is pulled out of the installation hole in the nail core together with the pressure rod. Because the material used for the expansion block has resilience, after the pressure rod is pulled out from the installation hole, the expansion block will automatically rebound, thereby achieving the purpose of facilitating the disassembly of the rivet.
