Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a striking tool for installing scaffolding fasteners. Background Art

[0002] Scaffolding is an integral part of building construction, primarily used to support the building structure and provide a construction platform. During scaffolding construction, numerous fasteners are required to connect components such as steel pipes, ensuring the stability and safety of the entire scaffolding system. Traditional fastener installation relies primarily on manual tightening, a method that is not only inefficient but also prone to operator fatigue over long periods of time, potentially leading to occupational illnesses.

[0003] At present, workers mostly use a wrench to knock on the screws during installation. However, the wrench has a small knocking area, which can easily cause the fastener to deform. In addition, during the knocking process, the collision between the tool and the fastener will generate a large reaction force, which is directly transmitted to the operator's hand. Long-term work will cause arm soreness and even vibration disease. Therefore, a knocking tool for scaffold fastener installation is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] See also Figure 1-Figure 5 A striking tool for installing scaffolding fasteners includes a striking head 100 and a movable jaw 101. The striking head 100 is provided with a wrench 1001, and the movable jaw 101 is movably installed in the wrench 1001. A rotatably connected expansion plate 200 is provided on the side of the striking head 100, and a movably connected handle 300 is provided at the bottom of the striking head 100.

[0023] An axis hole 1004 is provided at the bottom of the handle 300 striking head 100, an axis hole 1004 is provided on the handle 300, a rotating shaft 3001 cooperating with the axis hole 1004 is provided on the handle 300, a pressure rod 3002 is provided on the handle 300, a second spring 303 is provided between the pressure rod 3002 and the striking head 100, and the striking head 100 and the handle 300 are elastically rotatably connected via the second spring 303.

[0024] The elastically rotatably connected striking head 100 and handle 300 can reduce the vibration of the hand during striking and improve the comfort of the device.

[0025] Furthermore, a guide rod 1002 is provided in the wrench 1001 , and a guide hole 1011 is provided on the movable jaw 101 to cooperate with the guide rod 1002 . The movable jaw 101 and the striking head 100 are slidably connected through the guide rod 1002 and the guide hole 1011 .

[0026] The sliding connection of the movable jaw 101 allows it to slide along the guide rod 1002, thereby changing the size of the wrench 1001 to accommodate bolts of different sizes.

[0027] Furthermore, a first spring 103 is provided between the movable jaw 101 and the striking head 100, a first screw hole 1003 is provided on the striking head 100, a first knob 102 threadedly engaged with the striking head 100 is provided in the first screw hole 1003, the top of the first knob 102 is a spherical top structure, and the bottom edge of the movable jaw 101 is a sloped structure.

[0028] The height of the wrench 1001 is adjusted by rotating the first knob 102. When the first knob 102 moves upward, the first knob 102 squeezes the bottom edge of the movable jaw 101, causing the movable jaw 101 to move sideways, thereby changing the size of the wrench 1001. When the first knob 102 moves downward, the movable jaw 101 is reset under the action of the spring.

[0029] Furthermore, there are two expansion plates 200 , and the two groups of expansion plates 200 are mirror-mounted on the front and rear sides of the striking head 100 . The expansion plates 200 are right-angled triangular prism structures, and a damping hinge 201 is provided between the expansion plates 200 and the striking head 100 .

[0030] The expansion plate 200 can be flipped outward along the damping hinge 201 to enlarge the striking area and improve the striking efficiency, or it can be folded sideways to form an axe-shaped structure to facilitate the disassembly of fasteners and improve the disassembly efficiency.

[0031] Furthermore, a second knob 301 is provided on the pressure rod 3002, a sleeve 302 is provided at the front end of the second knob 301, a slide groove 3021 is provided on the sleeve 302, a second spring 303 is sleeved on the second knob 301, the second knob 301 is inserted into the slide groove 3021 and is elastically slidably connected to it through the second spring 303, and a limiting portion 3004 is provided on the pressure rod 3002 side of the handle 300.

[0032] When the device is striking, the striking head 100 drives the shaft sleeve 302 to move, causing it to press the second spring 303, thereby achieving the purpose of adjusting shock absorption.

[0033] Furthermore, a second screw hole 3003 is provided on the pressure rod 3002, and an external thread matching the second screw hole 3003 is provided on the second knob 301. The second knob 301 is inserted into the second screw hole 3003 and is slidingly connected to the pressure rod 3002. The top of the sleeve 302 is an arc surface structure, and the sleeve 302 is in sliding contact with the striking head 100.

[0034] By rotating the second knob 301 , the depth of the second knob 301 inserted into the slide groove 3021 is adjusted, and the sliding stroke of the second knob 301 is changed until the second knob 301 is fully inserted into the slide groove 3021 , thereby realizing the conversion between the elastic connection and the rigid connection.

[0035] Furthermore, a ventilation hole 3022 is provided at the bottom of the side end surface of the slide groove 3021.

[0036] The air is slowly exhausted through the air holes 3022, so that a damping effect is formed between the shaft sleeve 302 and the knob, thereby improving the shock absorption effect.

[0037] When the present device is in use, first, according to the size of the bolt or nut to be tightened or loosened, the size of the spanner 1001 is adjusted by rotating the first knob 102. When the first knob 102 rises, it squeezes the inclined portion of the movable jaw 101, causing the movable jaw 101 to move outward, thereby expanding the size of the spanner 1001; when the first knob 102 falls, under the action of the first spring 103, the movable jaw 101 returns to its initial position, and the size of the spanner 1001 is reduced. When the fastener needs to be installed on the scaffold, in order to ensure that the fastening clamp is clamped, the expansion plate 200 can be flipped outward along the damping hinge 201 to increase the knocking area, and the scaffolding fastener can be knocked with a tool close to the side end surface of the expansion plate 200 to make the fastener fit. At this time, The handle 300 on the knocking head 100 is used to perform the knocking action. During use, the elastic rotation connection design between the handle 300 and the knocking head 100 reduces the vibration transmitted to the operator's hand during the knocking process. In addition, the design of the second spring 303 and the second knob 301 also allows a certain degree of shock absorption. By rotating the second knob 301, the depth of its insertion into the slide groove 3021 can be adjusted, thereby changing the shock absorption effect. If the fastener needs to be removed, the tool can be used as a crowbar to fold the expansion plate 200 to the side to form an axe-shaped structure, and hammer the gap of the fastener to separate the fastener. When installing the fastener, align the wrench 1001 with the fastener bolt or nut that needs to be tightened, and ensure that the wrench 1001 correctly clamps the bolt or nut for tightening and installation.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
