Technical Field
[0001] This invention relates to the field of hammer technology, specifically a hammer handle structure for fixing the hammer head to prevent it from falling off. Background Technology
[0002] A hammer is a tool used to strike objects, causing them to move or deform. It is most commonly used to drive nails, straighten things, or break objects apart. Hammers come in various forms, the most common being a handle and a top. One side of the top is flat for striking, and the other side is the hammerhead. The hammerhead can be shaped like a ram's horn or a wedge, its function being to pull out nails. There are also round-headed hammers.
[0003] The hammer head and handle of a hammer are usually connected by an interference fit. The handle is inserted into the hammer head for use. During use, the hammer head will receive a reaction force from the object it hits each time, which may cause the hammer head to vibrate and wobble. The reaction force on the hammer head will also act on the connection between the hammer head and the handle. If the hammer head is tilted when it comes into contact with an object, the reaction force will also act on the connection between the hammer head and the handle at an angle. The handle is usually made of metal or wood. After prolonged use, the area of concentrated force on the handle may deform, which may cause the hammer head to wobble or fall off when using the hammer. Summary of the Invention
[0004] To address the problems in the prior art, the present invention provides a hammer handle structure for fixing the hammer head to prevent it from falling off.
[0005] The technical solution adopted by the present invention to solve its technical problem is: a hammer handle structure for fixing the hammer head to prevent it from falling off, comprising: a handle, and a hammer head being sleeved on one end of the handle;
[0006] A connector is integrally formed with the handle, the connector is located at the end of the handle, and the hammer head is inserted into the outside of the connector;
[0007] A rubber gasket is fixedly sleeved at the connection between the plug and the handle; a limit component is provided inside the plug, and an adjustment component is provided inside the handle;
[0008] The connector is equipped with a clamping component, which includes an adjusting block. The connector has a storage groove in the middle, and the adjusting block is slidably connected in the storage groove. A moving spring is provided between the inner wall of the storage groove and the adjusting block. Multiple inclined grooves are provided on both sides of the adjusting block. Multiple sets of through holes are opened on the side wall of the connector. An anti-detachment rod is slidably installed in one of the through holes. The end of the anti-detachment rod placed outside the connector can abut against the outer wall of the hammer head. The end of the anti-detachment rod placed inside the storage groove is matched with the inclined grooves on both sides of the adjusting block.
[0009] Specifically, the outer wall of the connector is provided with a corrugated abutment plate, which is fixedly connected to the side wall of the handle. The corrugated abutment plate is made of metal material. The hammer head is provided with a groove that matches the corrugated abutment plate. A retaining rod slides through the middle of the connector. The end of the retaining rod near the outside of the connector is pressed against the corrugated abutment plate. The end of the retaining rod inside the connector is matched with the inclined grooves provided on both sides of the adjusting block.
[0010] Specifically, the limiting component includes a limiting concave block, the middle of which contacts the end of the connector, the limiting concave block is slidably connected in the storage groove, and recycling grooves are provided on both outer walls of the limiting concave block. A snap-fit wedge is provided in the recycling groove, the snap-fit wedge is arranged in a parallelogram shape, a triangular fixing block is provided on the inner wall of the connector, and the end of the snap-fit wedge placed outside the recycling groove cooperates with the triangular fixing block.
[0011] Specifically, a pressing push block is slidably provided on the inner wall of the recycling tank. The pressing push block contacts one end of the locking inclined block placed inside the recycling tank. A pressing spring is fixedly connected to one end of the pressing push block, and the other end of the pressing spring is fixedly connected to the inner side wall of the recycling tank.
[0012] Specifically, a connecting cylinder is fixedly connected to the end of the limiting concave block away from the adjusting block, and the adjusting assembly includes a threaded rod that passes through the middle of the handle, with one end of the threaded rod inserted into the connecting cylinder.
[0013] Specifically, a limiting ring groove is formed on the inner wall of the connecting cylinder, and a sliding ring is slidably disposed in the limiting ring groove. A limiting ring is fixedly connected to the outer wall of one end of the threaded rod placed inside the connecting cylinder, and the outer diameter of the limiting ring is larger than the inner diameter of the sliding ring.
[0014] Specifically, one end of a pull rope is fixedly connected to one side of the sliding ring, and the other end of the pull rope passes through the recycling trough. The end of the pull rope placed in the recycling trough is fixedly connected to the pressing push block.
[0015] Specifically, the outer wall of the threaded rod is threaded with an adjusting wheel, the middle of the handle has a rotating hole that matches the adjusting wheel, and the outer wall of the adjusting wheel is provided with multiple anti-slip balls.
[0016] Specifically, the handle is threaded with a threaded knob, a return spring is fixedly connected to the inner wall of the rotating hole, a friction plate is fixedly connected to the end of the return spring away from the inner wall of the rotating hole, and the end of the threaded knob placed in the rotating hole contacts the outer wall of the friction plate, so that the friction plate can abut against the outer wall of the adjusting wheel.
[0017] The beneficial effects of this invention are:
[0018] (1) The hammer handle structure for fixing the hammer head to prevent it from falling off, as described in this invention, can push the anti-detachment locking rod to the outside of the connector through the inclined grooves set on both sides by the movement of the adjusting block, which can block the hammer head. When the hammer head is in a rotating state when hitting an object, it will generate outward centrifugal force. The anti-detachment locking rod directly blocks the hammer head, preventing the hammer head from detaching from the connector under the action of centrifugal force. At the same time, under the action of centrifugal force, the hammer head will be pressed more tightly against the anti-detachment locking rod, preventing the hammer head from shaking during the downward hitting process.
[0019] (2) The hammer handle structure for fixing the hammer head to prevent it from falling off, as described in this invention, has a clamping rod that can clamp the corrugated clamping plate against the inner wall of the hammer head, thus playing a role in preventing slippage. During the downward swing of the hammer head, under the action of centrifugal force, the adjusting block tends to move towards the end of the receiving groove, further clamping the adjusting block more firmly, ensuring that the hammer head will not shake during the downward hammering process.
[0020] (3) The hammer handle structure for fixing the hammer head and preventing it from falling off, as described in this invention, allows the snap-fit inclined block to slide into the recycling groove when the hammer head needs to be replaced or removed. At this time, the limiting concave block can move away from the adjusting block, and the adjusting block will move closer to the limiting concave block under the push of the moving spring. The anti-falling clip rod can enter the storage groove under the push, and the hammer head can be removed, saving time and effort.
[0021] (4) The hammer handle structure for fixing the hammer head to prevent it from falling off, as described in this invention, after the hammer head is fixed, rotate the threaded knob so that the end of the threaded knob placed inside the rotating hole pushes the friction plate against the outer wall of the adjusting wheel to prevent the adjusting wheel from rotating when the hammer head is used to hit an object, which would cause the threaded rod to loosen and the hammer head to fall off.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0036] like Figures 1-8 As shown, the hammer handle structure for fixing the hammer head to prevent it from falling off, according to the present invention, includes: a handle 2, and a hammer head 1 is sleeved on one end of the handle 2.
[0037] Connector 21: Connector 21 is integrally formed with handle 2, and connector 21 is located at the end of handle 2. The hammer head 1 is inserted into the outside of connector 21.
[0038] Rubber gasket 3: The rubber gasket 3 is fixedly sleeved at the connection between the plug 21 and the handle 2; the plug 21 is provided with a limit component 7, and the handle 2 is provided with an adjustment component 4;
[0039] The connector 21 is provided with a clamping component 6, which includes an adjusting block 61. The connector 21 has a storage groove 211 in the middle. The adjusting block 61 is slidably connected in the storage groove 211. A moving spring 64 is provided between the inner wall of the storage groove 211 and the adjusting block 61. Multiple inclined grooves are provided on both sides of the adjusting block 61. Multiple sets of through holes are opened on the side wall of the connector 21. An anti-detachment rod 63 is slidably provided in one of the through holes. The end of the anti-detachment rod 63 placed outside the connector 21 can be clamped against the outer wall of the hammer head 1. The end of the anti-detachment rod 63 placed inside the storage groove 211 is matched with the inclined grooves on both sides of the adjusting block 61.
[0040] When smashing an object, the force exerted by the hammer on the handle 2 is mostly concentrated at the rubber pad ring 3. The rubber pad ring 3 can play a buffering role, reducing the impact of the buffering force on the handle 2, increasing the service life of the handle 2, and also reducing the vibration of the handle 2 when smashing an object. At the same time, the rubber pad ring 3 can press tightly against the inner wall of the hammer head to prevent the hammer head from slipping off.
[0041] By moving the adjusting block 61, the anti-detachment lever 63 can be pushed outward of the connector 21 through the inclined grooves on both sides, which can block the hammer head 1. When the hammer head 1 is in a rotating state when hitting the object, it will generate outward centrifugal force. The anti-detachment lever 63 directly blocks the hammer head 1, preventing the hammer head 1 from detaching from the connector 21 under the action of centrifugal force. At the same time, under the action of centrifugal force, the hammer head 1 will be pressed more tightly against the anti-detachment lever 63, preventing the hammer head 1 from shaking during the downward smashing process.
[0042] Specifically, the outer wall of the connector 21 is provided with a corrugated abutment plate 22, which is fixedly connected to the side wall of the handle 2. The corrugated abutment plate 22 is made of metal. The hammer head 1 is provided with a groove that matches the corrugated abutment plate 22. A retaining rod 62 slides through the middle of the connector 21. One end of the retaining rod 62 near the outside of the connector 21 is abutted against the corrugated abutment plate 22. The end of the retaining rod 62 inside the connector 21 is engaged with the inclined grooves provided on both sides of the adjusting block 61.
[0043] During the movement of the adjusting block 61, the clamping rod 62 is also pushed to move towards the outside of the connector 21. The clamping rod 62 can press the corrugated clamping plate 22 against the inner wall of the hammer head 1, which plays a role in preventing slippage. During the downward swing of the hammer head 1, under the action of centrifugal force, the adjusting block 61 tends to move towards the end of the receiving groove 211, further pressing the adjusting block 61 more firmly, ensuring that the hammer head 1 will not shake during the downward strike.
[0044] Specifically, the limiting component 7 includes a limiting concave block 71, the middle of which contacts the end of the connector 21. The limiting concave block 71 is slidably connected in the storage groove 211. Both outer walls of the limiting concave block 71 are provided with recycling grooves 711. A snap-fit inclined block 72 is provided in the recycling groove 711. The snap-fit inclined block 72 is arranged in a parallelogram shape. A triangular fixing block 23 is provided on the inner wall of the connector 21. One end of the snap-fit inclined block 72, which is placed outside the recycling groove 711, cooperates with the triangular fixing block 23.
[0045] By engaging the inclined block 72 and the triangular fixing block 23, the adjusting block 61 can be pressed against the limiting concave block 71, preventing the adjusting block 61 from moving towards the handle 2 when the hammer head 1 hits an object, thus preventing the hammer head 1 from becoming loose. The recycling groove 711 serves to store the hammer head. At the same time, when the hammer head needs to be replaced or removed, the inclined block 72 can slide into the recycling groove 711. At this time, the limiting concave block 71 can move away from the adjusting block 61. Under the push of the moving spring 64, the adjusting block 61 will move towards the limiting concave block 71. The anti-disengagement lever 63 can enter the recycling groove 211 under the push, and the hammer head 1 can be removed, which is convenient and quick.
[0046] Specifically, a pressing push block 73 is slidably provided on the inner wall of the recycling tank 711. The pressing push block 73 contacts one end of the locking inclined block 72 placed inside the recycling tank 711. A pressing spring 74 is fixedly connected to one end of the pressing push block 73, and the other end of the pressing spring 74 is fixedly connected to the inner side wall of the recycling tank 711.
[0047] The clamping spring 74 pushes the clamping push block 73 so that the clamping push block 73 and the snap-fit inclined block 72 are in a clamping state. The clamping push block 73 can attract the contact surface with the snap-fit inclined block 72. When the contact surfaces of the clamping push block 73 and the snap-fit inclined block 72 slide relative to each other, the contact surfaces of the clamping push block 73 and the snap-fit inclined block 72 are still in contact.
[0048] Specifically, the end of the limiting concave block 71 away from the adjusting block 61 is fixedly connected to the connecting cylinder 76, and the adjusting component 4 includes a threaded rod 42 that passes through the middle of the handle 2, with one end of the threaded rod 42 inserted into the connecting cylinder 76.
[0049] The threaded rod 42 presses against the limiting concave block 71 through the connecting cylinder 76, thereby ensuring that the hammer head 1 will not wobble during operation.
[0050] Specifically, a limiting ring groove 761 is formed on the inner wall of the connecting cylinder 76, and a sliding ring 762 is slidably disposed in the limiting ring groove 761. The limiting ring 42 is fixedly connected to the outer wall of one end of the threaded rod 42 inside the connecting cylinder 76. The outer diameter of the limiting ring 421 is larger than the inner diameter of the sliding ring 762.
[0051] When it is necessary to replace the hammer head 1, adjust the threaded rod 42 away from the limiting concave block 71. The limiting ring 421 will pull the sliding ring 762 away from the limiting concave block 71. At the same time, the pulling rope 75 will pull the pressing push block 73 along the inner wall of the recycling groove 711 in the same direction. The locking inclined block 72 will retract into the recycling groove 711. Under the push of the moving spring 64, the adjusting block 61 will move closer to the limiting concave block 71. The anti-detachment locking rod 63 can enter the storage groove 211 under the push, and the hammer head 1 can be removed, which is convenient and quick.
[0052] Specifically, one end of a pull rope 75 is fixedly connected to one side of the sliding ring 762, and the other end of the pull rope 75 passes through the recycling trough 711. The end of the pull rope 75 placed in the recycling trough 711 is fixedly connected to the pressing push block 73.
[0053] Adjust the threaded rod 42 away from the limiting concave block 71. The limiting ring 421 will pull the sliding ring 762 away from the limiting concave block 71. At the same time, the pulling rope 75 will pull the pressing push block 73 along the inner wall of the recycling groove 711 in the same direction. The locking inclined block 72 will retract into the recycling groove 711. Under the push of the moving spring 64, the adjusting block 61 will move closer to the limiting concave block 71. The anti-detachment locking rod 63 can enter the storage groove 211 under the push, and the hammer head 1 can be removed, which is convenient and quick.
[0054] Specifically, the outer wall of the threaded rod 42 is threaded with an adjusting wheel 41, the handle 2 has a rotating hole in the middle that matches the adjusting wheel 41, and the outer wall of the adjusting wheel 41 is provided with multiple anti-slip balls.
[0055] Rotating the adjusting wheel 41 allows the threaded rod 42 to move along the inside of the handle 2, thereby controlling the threaded rod 42 to press against the connecting cylinder 76 and preventing the hammer head 1 from falling off. When it is necessary to remove the hammer head 1, simply rotate the adjusting wheel 41 in the opposite direction to move the threaded rod 42 away from the hammer head 1. Anti-slip balls prevent slippage when rotating the adjusting wheel 41.
[0056] Specifically, the handle 2 is threaded with a threaded knob 11, and a return spring 14 is fixedly connected to the inner wall of the rotating hole. A friction plate 13 is fixedly connected to the end of the return spring 14 away from the inner wall of the rotating hole. The end of the threaded knob 11 placed in the rotating hole contacts the outer wall of the friction plate 13, and the friction plate 13 can abut against the outer wall of the adjusting wheel 41.
[0057] After the hammer head 1 is fixed, rotate the threaded knob 11 so that the end of the threaded knob 11 placed inside the rotating hole pushes the friction plate 13 against the outer wall of the adjusting wheel 41 to prevent the adjusting wheel 41 from rotating when the hammer head 1 is used to hit an object, which would cause the threaded rod 42 to loosen and the hammer head 1 to come off. When the threaded rod 42 needs to be adjusted, rotate the threaded knob 11 to move away from the adjusting wheel 41. Under the action of the return spring 14, the friction plate 13 separates from the outer wall of the adjusting wheel 41, and the adjusting wheel 41 can rotate smoothly.
