Description

Technical Field

[0001] The invention relates to the technical field of key production, in particular to a pin remover. Background Art

[0002] As people's living standards continue to improve, cars have become a common means of transportation. Most car keys use electronic signal remote control to control the car doors, etc. Some car keys are remotely controlled by electronic signals and are also connected to a mechanical key through a pin structure, and the pin structure is used to pull out and retract the mechanical key.

[0003] Car keys may be damaged during use. For example, the circuit inside the electronic key of a car key is prone to damage. In this case, the electronic key needs to be replaced. In order to save resources, when repairing a car key, the mechanical key of the car key is usually removed from the electronic key and replaced with a normal electronic key. At this time, the pin in the pin structure needs to be removed to facilitate the replacement of the electronic key. However, due to the position of the pin, the pin in the pin structure usually needs to be rotated to a certain angle to be visible. The current method for removing the pin is usually to match the ejector pin with the pin hole, and then knock the pin out of the pin hole by applying an external force to the ejector pin. This method has a too narrow force surface and directly applies force to the pin. It is difficult to control the direction of the force and the direction of the pin removal to remain in the same straight line, which can easily break the pin or ejector pin, making it very difficult to remove the pin. At the same time, since the pin hole is very small, the installation of the pin is also difficult. Summary of the invention

[0022] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0023] The following is combined with Figure 1-4 The present invention is described in detail:

[0024] The present invention provides a pin remover, such as Figure 1As shown, it includes: a frame 1, a pressing piece 2, a pushing component 3, and a driving mechanism; the frame 1 is provided with a recessed portion; the pressing piece 2 is provided at one end of the frame 1, and the pressing piece 2 is convexly provided relative to the upper end surface of the frame 1; the pushing component 3 includes a pushing platform 31, the pushing platform 31 is provided in the recessed portion, and the end of the pushing platform 31 facing the pressing piece 2 is provided with a push pin 32 and / or a pin hole 33; the output end of the driving mechanism is connected to the pushing platform 31, and when the driving mechanism drives the pushing component 3 to move toward the pressing piece 2, the pushing platform 31 moves linearly toward the pressing piece 2.

[0025] In the present embodiment, the pressing member 2 is fixedly mounted on one end surface of the frame 1, and a boss is provided at the part of the recessed portion close to the pressing member 2 to facilitate the bearing of the key. In other embodiments, the pressing member 2 can also be integrally formed with the frame 1; an ejector pin 32 and a pin hole 33 are provided at one end of the pushing platform 31 facing the pressing member 2, and the pin hole 33 and the ejector pin 32 are respectively axially arranged on both sides of the pushed platform 31 in parallel, and a pin hole 21 is provided at the protruding portion of the pressing member relative to the frame, so that the ejector pin 32 disengages the pin from the pin hole 21; in other embodiments, the ejector pin 32 or the pin hole 33 can be provided separately; when the pin needs to be removed, the car key is placed between the pressing member 2 and the pushing platform 31, and the ejector pin 32 is inserted into the pin hole of the key pin to drive the key. The push pin 32 cooperates with the push pin 2 to push out the pin, and the pin comes out of the pin outlet hole 21; the push pin 32 moves linearly, and the force directly acting on the push pin 32 is dispersed to the push platform 31, which has good mechanical properties and reduces the risk of deformation and breakage of the push pin 32 or the pin, and a driving device is provided to drive the push platform 31; when the pin needs to be installed, the key is placed between the push pin 2 and the push platform 31, and the pin is placed in the pin installation hole 33, and force is applied to the driving mechanism, and the driving mechanism drives the push component 3 to move toward the push pin 2, and the push pin 2 cooperates with the push platform 31 to install the pin, which can realize the removal of the pin in the car key and the installation of the pin in the car key, and has a simple structure and is convenient and quick to use.

[0026] In one embodiment, in combination Figure 2 and Figure 3 As shown, the driving mechanism includes a force-applying part 41 and a transmission member 42, the force-applying part 41 and the transmission member 42 are rotatably connected, and the connection between the force-applying part 41 and the transmission member 42 is set to be eccentric, and the upper end of the transmission member 42 is engaged with the lower end of the pushing platform 31; the pushing platform 31 is penetrated by a guide rod 311, and the frame 1 is provided with a through hole 22 for allowing the guide rod 311 to pass through.

[0027] The eccentric rotation setting of the transmission member 42 is convenient for reducing the force, thereby reducing the force applied to the force-applying part 41. The eccentric rotation setting plus the guide rod 311 make the output direction of the transmission member 42 a straight line, thereby making the pushing platform 31 move in a straight line, and the guide rod 311 can disperse the force on the ejector pin 32, reduce the risk of breakage of the ejector pin 32, make the pin easier to remove, and not easy to bend and deform; in this embodiment, two guide rods 311 are provided, and two through holes 22 are also correspondingly provided. The two guide rods 311 and the line connecting the centers of the two guide rods 311 are parallel to the ground, so that the pushing platform 31 moves more smoothly and disperses the force on the ejector pin 32 more evenly, further reducing the risk of breakage of the ejector pin 32.

[0028] In one embodiment, the driving mechanism also includes: a connecting member 44, a sliding member 43 and an elastic element 45, one end of the connecting member 44 is connected to the sliding member 43, the elastic element 45 is connected to the end of the connecting member 44 facing the sliding member 43, the other end of the connecting member 44 is connected to one side of the force-applying portion 41, and the other end of the elastic element 45 is connected to the transmission member 42; a sliding groove is provided on the upper end surface of the sliding member 43, and a fixed rod 431 is slidably provided in the sliding groove, and the fixed rod 431 is fixedly connected to the frame 1; when force is applied to the force-applying portion 41, the connecting member 44 drives the sliding member 43 to move relative to the frame 1.

[0029] In this embodiment, a slide groove is provided on the sliding member 43, and a fixed rod 431 is slidably provided in the slide groove. The sliding member 43 is connected to the frame 1 through the fixed rod 431, so that the sliding member 43 can move relative to the frame 1. When force is applied to the force-applying part 41, the force-applying part 41 drives the connecting member 44 to move, so that the sliding member 43 moves toward the top pressure member 2. At the same time, the connecting member 44 drives the elastic element 45, and the elastic element 45 lifts the transmission member 42, so that the transmission member 42 engages with the pushing platform 31, thereby driving the pushing platform 31 to move toward the top pressure member 2.

[0030] In one embodiment, in combination Figure 3 and Figure 4 As shown, the pin remover also includes a cylindrical pawl 5, and a concave cavity 13 for placing the cylindrical pawl 5 is provided in the frame 1. The upper end surface of the cylindrical pawl 5 includes a ratchet surface and an inclined surface. The ratchet surface of the cylindrical pawl 5 and the upper end of the transmission member 42 are jointly engaged with the lower end of the pushing platform 31; and when the ratchet surface of the cylindrical pawl 5 is engaged with the lower end of the pushing platform 31, a cavity is formed between the inclined surface and the pushing platform 31, and the cavity is for the transmission member 42 to move along the inclined surface.

[0031] In this embodiment, the concave cavity 13 is arranged in the frame 1 and is connected to the bottom surface of the recessed portion. The inclined surface cooperates with the transmission member 42, and the high ratchet surface cooperates with the ratchet surface at the bottom of the pushing platform 31. The cylindrical pawl 5 and the transmission member 42 and the pushing platform 31 form a ratchet mechanism. When the force applied to the force-applying portion 41 is withdrawn, the transmission member 42 moves downward and then disengages from the pushing platform 31. At this time, the cylindrical pawl 5 is still engaged with the pushing platform 31. When the force is applied to the force-applying portion 41 again, the transmission member 42 is lifted up, so that the transmission member 42 is engaged with the pushing platform 31 again, and the downward movement is performed. The pushing platform 31 is driven once to press the force applying part 41, and the ratchet mechanism is driven to move through the transmission member 42, so that when holding the force applying part 41, a large distance is not required, and a large force is not required to hold it, which is convenient for taking out or installing the pin, and the pushing platform 31 slowly pushes the pin out several times, so that when the pin is removed, the force on the ejector pin 32 is more evenly distributed, and the ejector pin 32 is prevented from being broken by excessive force, thereby reducing the possibility of the ejector pin 32 breaking. The pin is removed or installed by pressing the force applying part 41 multiple times, and the operation is simple, and the pin can be quickly removed.

[0032] In one embodiment, a first elastic member (not shown in the figure) is further provided inside the cylindrical pawl 5, and the first elastic member extends toward the lower end of the cylindrical pawl 5 when in a natural state; the pin remover also includes a rear seat 6, which is connected to an end of the frame 1 away from the top pressure member 2 through a second elastic member 7, and a separating member 61 is provided on a side of the rear seat 6 facing the frame 1, and a force is applied to the rear seat 6 toward the frame 1 so that the separating member 61 is inserted between the cylindrical pawl 5 and the pushing platform 31.

[0033] In this embodiment, the first elastic member (not shown in the figure) is a spring, the second elastic member 7 is also configured as a spring, and the end of the separator 61 inserted between the cylindrical pawl 5 and the pushing platform 31 is configured as a wedge-shaped structure. The wedge-shaped structure has an inclined surface, which makes it easier to insert the separator 61. When the pin is removed or installed successfully, the rear seat 6 is pushed, the elastic member is compressed, and the separator 61 is inserted between the cylindrical pawl 5 and the pushing platform 31. The separator 61 presses the transmission member 42 downward, and the frame 1 cooperates with the cylindrical pawl 5 to compress the internal spring of the cylindrical pawl 5. The cylindrical pawl 5 continues to move downward, and the cylindrical pawl 5 is separated from the pushing platform 31, and force is applied to the pushing platform 31, thereby returning the pushing platform 31, and resetting the pushing platform 31 with one button, so as to carry out the next round of pin removal or pin installation. When the rear seat 6 is released, the second elastic member 7 is naturally stretched, so that the rear seat 6 returns to its natural state; the operation is simple.

[0034] In one embodiment, in combination Figure 1 and Figure 2 The pin remover also includes a tension spring 8, one end of the tension spring 8 is connected to the push platform 31, and the other end of the tension spring 8 is connected to an end of the frame 1 away from the top pressure piece 2.

[0035] When the cylindrical pawl 5 and the pushing platform 31 are separated, the tension spring 8 provides a pulling force to make the pushing platform 31 return to its original position automatically.

[0036] In one embodiment, the push platform 31 and the ejector pin 32 are detachably connected. In this embodiment, a card slot 312 is provided at the end of the push platform 31 facing the ejector 2, and a card block is provided at the ejector pin 32. The card block of the ejector pin 32 is carded in the card slot 312, so that the push platform 31 is detachable and easy to install; at the same time, according to different key models, the diameter or length of the ejector pin 32 is provided with different models and specifications, so that the pin remover is more practical.

[0037] In one embodiment, a magnet block 9 is provided on the push platform 31 (see Figure 1 ).

[0038] In this embodiment, a placement groove 313 is provided on the pushing platform 31, and a magnet block 9 is placed on the placement groove 313, so that when installing the pin, the pushing platform 31 of the pin remover has magnetism, which is convenient for sucking the pin and then facilitating the installation of the pin.

[0039] In one embodiment, the frame 1 is a gun-shaped structure, including a main body 11 and a handle 12, and the recess is arranged on the main body 11. Preferably, the frame 1 is a gun-shaped structure, including a main body 11 and a handle 12, and the top pressure piece 2 and the rear seat 6 are both connected to the main body 11.

[0040] The frame 1 is configured as a gun shape, and this structural shape is more in line with people's usage habits and is convenient for people to hold and operate.

[0041] In one embodiment, the hand-held portion 12 is configured to be hollow.

[0042] In this embodiment, the force applying portion 41 is also hollowed out. The force applying portion 41 or the hand-held portion 12 is hollowed out to reduce the overall weight of the pin remover and the force required to be applied when people use it.

[0043] The principles of this embodiment are as follows:

[0044] After placing the key between the top pressure piece 2 and the pushing platform 31 and inserting the ejector pin 32 into the pin hole or the pin into the pin installation hole 33, the force applying part 41 is pressed, the force applying part 41 drives the transmission part 42 to move, the transmission part 42 drives the ratchet mechanism to move, and then the pushing platform 31 slows down and the ejector pin 32 moves toward the top pressure piece 2, so as to remove or install the pin; when the pin is removed or installed, the rear seat 6 is pushed, the second elastic member 7 is compressed, and the separating member 61 is inserted between the cylindrical pawl 5 and the pushing platform 31, the separating member 61 presses the cylindrical pawl 5 downward, the first elastic member inside the cylindrical pawl 5 is compressed, the transmission member 42 continues to move downward, the transmission member 42 and the pushing platform 31 are separated, the tension spring 8 returns the pushing platform 31, and then the pushing platform 31 is reset with one key, so as to carry out the next round of pin removal or pin installation.
