Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an octagonal hammer for building construction with a grip-resistant, anti-drop design. Background Technology

[0002] Building construction is one of the most critical aspects of building engineering, involving multiple aspects such as concrete pouring, steel reinforcement installation, structural erection, and decoration construction. During the construction process, various construction tools are needed to complete different tasks. In foundation construction, component installation, and material hammering and shaping, hammer tools are widely used due to their ease of operation and wide applicability. Among them, the octagonal hammer, with its hammerhead shape design, can effectively distribute the force when striking, making it suitable for various building conditions. Therefore, it has gradually become a commonly used tool in building construction.

[0003] Most existing octagonal hammers used in construction only have a single anti-slip structure on the handle. They enhance grip stability by adding friction texture to the outer wall, but the overall design still relies mainly on active hand control and lacks an anti-slip design that can accommodate the natural rotation of the worker's wrist. When sweat, dust, or prolonged use cause a decrease in grip strength during construction, the octagonal hammer is at risk of accidentally slipping. At the same time, although some octagonal hammers have a wrist strap added to the end of the handle for enhanced protection, it is usually fixed and non-removable. This structure is prone to getting tangled or hooked with other objects in narrow spaces or when frequent tool changes are required, affecting the flexibility of construction operations.

[0004] Therefore, this utility model proposes an octagonal hammer for building construction with a grip-resistant, anti-drop design. Utility Model Content

[0005] Therefore, in order to overcome the problems that existing octagonal hammers used in construction often adopt a single anti-slip handle, relying solely on friction texture to enhance stability, and lack an anti-slip design that can rotate with the wrist, they are prone to slipping when wet with sweat or used for a long time. Although some octagonal hammers have wrist straps at the end of the handle, they are mostly non-removable structures, which can easily cause entanglement and hooking in narrow spaces or when changing tools, affecting the flexibility of construction.

[0006] The technical solution of this utility model is as follows: an octagonal hammer for construction with a grip and anti-detachment type, comprising a connecting handle, a handle tail, and a rotating ball; an anti-detachment disc is fixedly connected to the bottom end of the connecting handle, and an anti-slip pad is fixedly connected to the end of the anti-detachment disc away from the connecting handle, the anti-slip pad being located near the center of the anti-detachment disc; the handle tail is fixedly connected to the end of the anti-slip pad away from the anti-detachment disc; a connecting seat is engaged inside the handle tail, the connecting seat being located near the center of the handle tail; and the rotating ball is rotatably connected inside the connecting seat.

[0007] Preferably, the anti-detachment disc has a disc-shaped structure, the anti-slip pad has anti-slip textures on its outer side wall, and the rotating ball has a spherical structure.

[0008] Preferably, a connecting washer is fixedly connected to the top of the connecting handle, and an octagonal hammerhead is fixedly connected to the outer wall of the connecting washer. The octagonal hammerhead is located away from the anti-detachment disc, and both ends of the octagonal hammerhead have an octagonal structure.

[0009] Preferably, a filling soft pad is fixedly connected to the inner wall of the anti-slip pad, and a handle core is fixedly connected to the inner wall of the filling soft pad. The filling soft pad and the handle core are fixedly connected to the bottom end of the anti-slip disc, and the handle tail is fixedly connected to the end of the filling soft pad and the handle core away from the anti-slip disc.

[0010] Preferably, a button is slidably connected inside the handle tail. The button is symmetrically installed near the connecting seat. A connecting shaft and a limiting rod are fixedly connected to the side of the button near the handle tail. The connecting shaft and the limiting rod are symmetrically installed near both ends of the button. The connecting shaft is slidably connected inside the handle tail. A return spring is sleeved on the outside of the limiting rod. One end of the return spring is fixedly connected inside the handle tail, and the other end of the return spring is fixedly connected to the side of the button near the handle tail.

[0011] Preferably, the connecting seat has a locking pin slidably connected inside, the locking pin is symmetrically installed near the end of the handle, the locking pin is slidably connected inside the end of the handle, the connecting shaft is close to the end of the locking pin away from the connecting seat, the end of the locking pin away from the connecting shaft is fixedly connected to a sliding seat, the sliding seat is slidably connected inside the connecting seat, the end of the sliding seat away from the locking pin is fixedly connected to a fastening spring, and the end of the fastening spring away from the sliding seat is fixedly connected inside the connecting seat.

[0012] Preferably, a rotating shaft is fixedly connected inside the rotating ball, the rotating shaft is located away from the connecting seat, and an anti-slip wristband is rotatably connected to the outer wall of the rotating shaft.

[0013] The beneficial effects of this utility model are: 1. During the use of the device, the operator puts the anti-slip wristband on their wrist. The anti-slip wristband can rotate around the rotation axis as the center, thus ensuring flexible and comfortable wearing. Then, the operator holds the anti-slip pad. The soft pad can fit the shape of the operator's hand, and the inner core of the handle ensures the overall strength of the grip. The anti-slip pad provides anti-slip support during construction and effectively absorbs sweat and oil from the palm through its anti-slip texture, maintaining stable friction with the skin and preventing slippage. The anti-slip disc forms a barrier against the palm, preventing it from sliding towards the connecting handle. The rotating ball on the connecting seat achieves a universal joint effect, allowing the anti-slip wristband to rotate freely with the wrist movement, preventing the anti-slip wristband from getting tangled, thus ensuring the safe and reliable operation of the device and preventing accidental slippage when the operator's grip strength decreases due to sweat, dust, or prolonged use during construction. 2. When the device needs to be used in a narrow environment, press both sets of buttons simultaneously to move them inwards towards the handle. The connecting shaft moves synchronously with the buttons, continuously compressing the locking pin and driving it to move inwards towards the connecting seat through the sliding seat. When the locking pin is completely disengaged from the handle and enters the connecting seat, the engagement between the connecting seat and the handle is released. At this time, pull the anti-detachment wrist strap to remove the connecting seat from the handle, thus completing the disassembly process of the device. Since the buttons have a dual structure, they must be pressed simultaneously to complete the disassembly, thereby achieving the anti-accidental touch effect. This prevents the anti-detachment wrist strap from getting tangled with other objects in narrow spaces or in environments where tools need to be changed frequently. 3. When the anti-slip wristband needs to be reassembled, align the connector and insert it into the handle end. When the connector is inserted to the deepest point, the fastening spring pushes the locking pin through the sliding seat, causing the locking pin to slide into the handle end. The connecting shaft then fits tightly against the outer end of the locking pin, preparing for the next disassembly, thus completing the anti-slip wristband reassembly process and achieving quick installation of the anti-slip wristband.

[0020] Please see Figures 1-7This utility model provides a technical solution: an octagonal hammer for construction with a grip and anti-detachment type, including a connecting handle 1, a handle tail 4, and a rotating ball 6; an anti-detachment disc 2 is fixedly connected to the bottom end of the connecting handle 1, and an anti-slip pad 3 is fixedly connected to the end of the anti-detachment disc 2 away from the connecting handle 1, the anti-slip pad 3 is located near the center of the anti-detachment disc 2, the handle tail 4 is fixedly connected to the end of the anti-slip pad 3 away from the anti-detachment disc 2, a connecting seat 5 is engaged inside the handle tail 4, the connecting seat 5 is located near the center of the handle tail 4, and the rotating ball 6 is rotatably connected inside the connecting seat 5.

[0021] The anti-slip disc 2 has a disc-shaped structure, and the outer wall of the anti-slip pad 3 has anti-slip texture. The rotating ball 6 has a spherical structure. The anti-slip disc 2 can effectively block the hand from sliding down and prevent the hand from sliding towards the connecting handle 1, thus improving the safety of holding. The anti-slip texture on the anti-slip pad 3 can increase the friction between the palm and the grip during construction. The spherical rotating ball 6 can achieve omnidirectional rotation during use.

[0022] A connecting washer 101 is fixedly connected to the top of the connecting handle 1, and an octagonal hammer head 102 is fixedly connected to the outer wall of the connecting washer 101. The octagonal hammer head 102 is located away from the anti-detachment disc 2. The two ends of the octagonal hammer head 102 are octagonal structures. The connecting washer 101 can make the connection between the octagonal hammer head 102 and the connecting handle 1 more stable and avoid loosening due to long-term impact.

[0023] A filling pad 301 is fixedly connected to the inner wall of the anti-slip pad 3, and a handle core 302 is fixedly connected to the inner wall of the filling pad 301. The filling pad 301 and the handle core 302 are fixedly connected to the bottom end of the anti-slip disc 2. The handle tail 4 is fixedly connected to the end of the filling pad 301 and the handle core 302 away from the anti-slip disc 2. The filling pad 301 makes the device flexible and comfortable to fit the hand shape when in use. At the same time, the handle core 302 provides sufficient structural strength to avoid deformation or breakage due to excessive force.

[0024] A button 401 is slidably connected inside the handle tail 4. The button 401 is symmetrically installed near the connecting seat 5. A connecting shaft 402 and a limiting rod 403 are fixedly connected to the side of the button 401 near the handle tail 4. The connecting shaft 402 and the limiting rod 403 are symmetrically installed near both ends of the button 401. The connecting shaft 402 is slidably connected inside the handle tail 4. A return spring 404 is sleeved on the outside of the limiting rod 403. One end of the return spring 404 is fixedly connected inside the handle tail 4, and the other end of the return spring 404 is fixedly connected to the side of the button 401 near the handle tail 4. The symmetrical arrangement of the buttons 401 maintains the synchronization of operation and achieves the effect of preventing accidental touch when disassembling components. After releasing external force on the button 401, the return spring 404 releases its elastic force to push the button 401 to reset. The limiting rod 403 prevents the return spring 404 from shaking, ensuring the reliability of the device after multiple operations.

[0025] The connecting seat 5 has a sliding connection of a locking pin 501 inside. The locking pins 501 are symmetrically installed near the handle tail 4. The locking pins 501 are slidably connected inside the handle tail 4. The connecting shaft 402 is close to the end of the locking pin 501 away from the connecting seat 5. The end of the locking pin 501 away from the connecting shaft 402 is fixedly connected to a sliding seat 502. The sliding seat 502 is slidably connected inside the connecting seat 5. The end of the sliding seat 502 away from the locking pin 501 is fixedly connected to a fastening spring 503. The end of the fastening spring 503 away from the sliding seat 502 is fixedly connected inside the connecting seat 5. The fastening spring 503 ensures that the locking pin 501 automatically returns to the locking position, realizing the automatic reset and relocking of the structure, and preventing loosening or falling off.

[0026] A rotating shaft 601 is fixedly connected inside the rotating ball 6. The rotating shaft 601 is located away from the connecting seat 5. An anti-detachment wristband 602 is rotatably connected to the outer wall of the rotating shaft 601. The anti-detachment wristband 602 can rotate flexibly around the rotating shaft 601. At the same time, the rotating ball 6 rotates in all directions within the connecting seat 5. When the operator performs multi-angle tapping, the anti-detachment wristband 602 can freely adjust its direction with the movement, avoiding the restriction of wrist movement by the anti-detachment wristband 602.

[0027] Working principle: See Figures 1-7 As shown, when the device is ready to be used, first, place the entire device in the work area, and hang the entire device on the external hook through the anti-slip wristband 602, and maintain the connection with the connecting handle 1 and the inner core of the handle 302 through the connecting seat 5 and the handle tail 4, thus completing the preparation before use. See Figures 3-7 As shown, during the use of the device, firstly, the worker puts the anti-slip wristband 602 on their wrist. The anti-slip wristband 602 can rotate in a circle around the rotation axis 601, thus ensuring flexibility and comfort when wearing it. Then, the worker holds the anti-slip pad 3. Since the filling pad 301 is made of flexible material, it can conform to the shape of the worker's hand. The innermost handle core 302 ensures the overall strength of the grip. At this time, the octagonal hammer head 102 is swung by the connecting handle 1 and the connecting washer 101, so that the device enters the construction position. In this process, the anti-slip pad 3 provides anti-slip support and effectively absorbs sweat and oil from the palm through its surface anti-slip texture, maintaining stable friction with the skin and preventing slippage. At the same time, the anti-slip disc 2 blocks the palm and prevents it from sliding towards the connecting handle 1. As the octagonal hammer 102 swings, the rotating ball 6 achieves a universal joint effect on the connecting seat 5, allowing the anti-slip wristband 602 to rotate freely with the wrist movement, preventing the anti-slip wristband 602 from getting tangled at the connection point with the connecting seat 5, thereby ensuring the safe and reliable operation of the device. See Figures 4-7As shown, when the device needs to be used in a narrow environment, firstly, press both sets of buttons 401 simultaneously with external force to make them overcome the elastic force of the return spring 404 and move into the handle tail 4. During this process, the limiting rod 403 limits the return spring 404 to prevent shaking and affect the action of the buttons 401. At this time, the connecting shaft 402 moves synchronously with the buttons 401, continuously compressing the locking pin 501 and driving it to move into the connecting seat 5 through the sliding seat 502 to overcome the elastic force of the fastening spring 503. When the locking pin 501 completely disengages from the handle tail 4 and enters the connecting seat 5, the engagement between the connecting seat 5 and the handle tail 4 is released. At this time, apply external force to pull the anti-disengagement wristband 602 to remove the connecting seat 5 from the handle tail 4, thereby realizing the disassembly process of the device. Since the buttons 401 have a dual structure, they must be pressed simultaneously to complete the disassembly, thereby achieving the anti-accidental touch effect. See Figures 4-7 As shown, when the anti-slip wristband 602 needs to be reassembled, first, align the connecting seat 5 and insert it into the handle tail 4. When the connecting seat 5 is inserted to the deepest point, under the elastic force of the fastening spring 503, the sliding seat 502 pushes the locking pin 501, causing the locking pin 501 to slide into the handle tail 4. The connecting shaft 402 then fits tightly against the outer end of the locking pin 501, preparing for the next disassembly, thus completing the reassembly process of the anti-slip wristband 602.

[0028] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
