Description

Technical Field

[0001] This utility model relates to the field of hammer technology, specifically a portable hammer for quality supervision and inspection of construction projects. Background Technology

[0002] Currently, the construction quality testing hammer is an indispensable tool in the supervision and inspection of construction project quality. It helps construction personnel to promptly identify and address quality issues with building materials, ensuring that project quality meets standard requirements. Simultaneously, the hammer test can also assess the overall structural safety of the building, providing crucial information for project acceptance and subsequent maintenance.

[0003] A portable hammer for quality supervision and inspection in construction engineering is disclosed in Chinese utility model patent application publication CN 216771603 U. This device utilizes a magnetic ring on the piston rod near a partition, creating an attractive force between the magnetic ring and the partition. The rebound of a spring coil further secures the piston rod to the partition. However, this device requires an external cylinder and is relatively heavy, making it inconvenient to carry. Utility Model Content

[0008] The mounting handle has its top end fixedly located below the hammer body. A fixing screw hole is provided on one side of the mounting handle. A connecting handle is fixedly located below the mounting handle by screws. A scale is fixedly located on one side of the connecting handle. A handle is movably located below the connecting handle. A handle groove is provided on one side of the handle. A portable column is fixedly located below the handle. A locking hole is provided on one side of the portable column. A hanging ring is movably located on the inner wall of the locking hole.

[0009] Preferably, the shock absorption mechanism includes shock absorption plates and shock absorption grooves. Shock absorption plates are movably disposed at both ends of the hammer body, and shock absorption grooves are formed at both ends of the hammer body. Shock absorption rods are movably disposed on the inner walls of the shock absorption grooves. The right side of the shock absorption rod is fixedly disposed on the left side of the shock absorption plate, and a baffle is fixedly disposed on one side of the shock absorption rod. A shock absorption spring is movably disposed on one side of the shock absorption rod, and the shock absorption spring is movably disposed on one side of the shock absorption groove. Under the action of the shock absorption plates at both ends of the hammer body, and with the action of the shock absorption spring installed in the shock absorption groove through the shock absorption rod on one side, a certain shock absorption effect is achieved, thereby reducing the damage caused to the hammer body by the hammer impact.

[0010] Preferably, the inner wall of the damping groove is provided with a positioning groove, and a positioning plate is movably disposed on the inner wall of the positioning groove. The right side of the positioning plate is fixedly disposed at one end of the damping rod, and a positioning hole is provided on one side of the positioning plate. A positioning rod is movably disposed on the inner wall of the positioning hole, and both ends of the positioning rod are fixedly disposed on the inner wall of the positioning groove. With the positioning plate and positioning rod installed in the positioning groove, the positioning of the damping plate can be restricted, the resistance of the positioning plate pushing backward can be blocked, and the hammering can play a role in assisting the damping plate.

[0011] Preferably, the installation mechanism includes an installation screw groove and an installation stud. The installation screw groove is provided on the right side of the shock-absorbing plate, and the installation stud is movably disposed on the inner wall of the installation screw groove. One end of each of the two installation studs has a flat hammer head and a convex hammer head, respectively. The flat hammer head and the convex hammer head are installed and fixed by the installation screw groove on one side of the shock-absorbing plate and the installation studs on the side of the flat hammer head and the convex hammer head on both sides of the hammer body.

[0012] Preferably, the adjustment mechanism includes an adjustment groove, an adjustment screw, and an adjustment tube. The adjustment tube is fixedly installed on the inner wall of the handle. An adjustment groove is opened at the bottom end of the connecting handle. The top end of the adjustment tube is movably installed on the inner wall of the adjustment groove. An adjustment screw is fixedly installed on the inner wall of the adjustment groove. The bottom end of the adjustment screw is movably installed on the inner wall of the adjustment tube. Fixed docking holes are opened on both sides of the connecting handle. A receiving screw groove is opened at the top end of the connecting handle. When the handle is rotated, the length of the handle can be adjusted by the interaction between the internally installed adjustment tube and the internally installed adjustment screw of the connecting handle.

[0013] Preferably, a storage groove is provided on the top of the hammer body, and a storage handle is movably disposed on the inner wall of the storage groove. A metal ball hammer is fixedly disposed at the top of the storage handle, and a storage stud is fixedly disposed at the bottom of the storage handle. The bottom of the storage stud is movably disposed on the inner wall of the storage screw groove. By connecting the storage screw groove at the top of the handle and the storage groove at the top of the hammer body, a small metal ball hammer can be placed and stored. When it is taken out, the metal ball hammer can be rotated to take it out, thereby achieving the storage effect.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This portable hammer for quality supervision and inspection in construction engineering comprises a hammer body, flat and convex hammer heads mounted on both sides, and a connecting handle and a handle at the bottom. The flat and convex hammer heads are installed and fixed by mounting grooves on one side of the shock-absorbing plate on both sides of the hammer body and mounting studs on the side of the flat and convex hammer heads. The connecting handle is then installed by screws through the mounting handle at the bottom of the hammer body. A small metal ball hammer can be placed and stored through the storage groove at the top of the connecting handle and the storage slot at the top of the hammer body. When the hammer is removed, it can be rotated to take it out, thus achieving the storage effect.

[0016] This portable hammer for quality supervision and inspection in construction engineering features a shock-absorbing design. When struck with a flat or convex hammer head, the hammer body benefits from the damping plates at both ends. A damping rod on one side, fitted with a damping spring within a damping groove, further reduces vibration and minimizes damage. A positioning plate and rod within a positioning groove limit the positioning of the damping plates and mitigate their resistance during impact, while also providing assistance during hammering. The handle, when rotated, allows for length adjustment via an internal adjusting screw and a connecting screw. A hanging loop at the bottom of the handle, attached to a portable post, facilitates easy carrying. Attached Figure Description

When it is taken out, the metal ball hammer 105 can be rotated to take it out, thus achieving the storage effect.

[0038] During the striking process using the flat hammer head 102 or the convex hammer head 103, the shock-absorbing plates 101 at both ends of the hammer body 100, along with the shock-absorbing rod 119 on one side and the shock-absorbing spring 121 installed in the shock-absorbing groove 118, provide a certain degree of shock absorption, thereby reducing the damage to the hammer body 100 caused by the hammering. The positioning plate 122 and the positioning rod 124 installed in the positioning groove 123 can limit the positioning of the shock-absorbing plate 101 and block the resistance of the positioning plate 122 pushing backward, thus providing assistance during the hammering. Furthermore, the handle 110 below can be rotated, and the length of the handle 110 can be adjusted by the interaction of the internally installed adjusting screw tube 129 and the internally installed adjusting screw 131 of the connecting handle 109. Finally, the hanging ring 115 installed at the bottom of the handle 110 via the carrying post 113 makes it convenient for the user to carry.
