Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, and in particular to a multi-functional hammer for construction engineering. Background Technology

[0002] In the field of construction engineering, the hammer, as a basic construction tool, primarily functions to fix, disassemble, or shape materials through striking. A traditional hammer typically consists of a hammerhead and a handle. The hammerhead is made of metal to ensure strength, while the handle is often made of wood or fiber-reinforced plastic to balance weight and grip comfort. However, in actual operation, the instantaneous contact between the hammer and the object being struck generates a significant reaction force, which is directly transmitted to the operator's arm and shoulder through the handle. Prolonged repetitive operation can easily lead to arm muscle fatigue, joint damage, and even occupational vibration-related illnesses, becoming a significant constraint on construction safety and work efficiency.

[0003] Furthermore, the complexity of construction projects requires workers to carry multiple tools simultaneously. For example, tightening operations require the use of screwdrivers. In traditional construction methods, workers need to carry separate tool bags, and frequent tool switching not only reduces the continuity of work but also affects mobility due to the weight and size limitations of the tools. Although modular tools (such as Swiss Army knife-type multi-tools) exist on the market, their functional integration is limited, and the strength and shock absorption performance of core components (such as hammers) often cannot meet the high-strength requirements of construction projects. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a multi-functional hammer for construction engineering. This design effectively solves the problems that the existing hammer body structure and function are simple and cannot meet the needs of actual use, and that during use, they can cause muscle fatigue, joint damage, and even occupational vibration disease to workers' arms.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a hammer body, a fixing hole extending longitudinally through the hammer body, a storage hole provided on the side of the fixing hole, the storage hole being placed laterally in the middle of the hammer body, a damper provided in the storage hole, a hammer handle provided on the side of the damper, and the hammer handle being fixedly connected to the fixing hole.

[0006] The damper includes a damping block, which is slidably connected to the storage hole. Both sides of the damping block are provided with pads, which are slidably connected to the storage hole. The outer sides of the two pads are provided with springs that apply force to the pads in the direction of the damping block, and the springs are located inside the storage hole.

[0007] Preferably, the lower end of the hammer handle is provided with a threaded hole, a connecting rod is threaded into the threaded hole, a handle support is fixedly connected to the connecting rod, a limit rod is installed between the handle support and the hammer handle, and a hexagonal wrench is fixedly connected to the outside of the handle support.

[0008] Preferably, the hammer handle is fitted with a rubber sleeve, the outer diameter of which is the same as the diameter of the handle support, and the rubber sleeve is provided with anti-slip texture.

[0009] Preferably, the connecting rod has a first slot, in which a screwdriver is connected; the hammer handle has a hexagonal slot; the connecting rod is an inscribed cylinder of the hexagonal slot; and the hexagonal slot engages with the hexagonal wrench.

[0010] Preferably, the screwdriver includes a connector head that engages with the first slot. One end of the connector head is fixedly connected to a wedge-shaped connector, and the other end of the connector head is provided with a second slot, in which a cross-shaped connector is connected.

[0011] Preferably, the hammer body includes a hammer head and a nail-removing head, the storage hole is located on the side near the hammer head, the nail-removing head has a hook-shaped structure, and a V-shaped nail-removing groove is opened in the middle of the nail-removing head.

[0012] Compared with the prior art, the outstanding advantages of this utility model are:

[0013] This invention features a storage hole and a damper inside the hammer body. The damper absorbs part of the reaction force, reducing the force exerted by the hammer handle on the worker's arm and protecting the worker's arm. It also helps to speed up the construction efficiency of the project.

[0014] This invention adds an extra tool component to the end of the hammer handle, thereby achieving the effect of multiple uses for one hammer, reducing the amount of tools workers need to carry, and expanding the applicable scenarios of the device. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see the appendix Figure 1-6 This embodiment discloses a multi-functional hammer for construction engineering: it includes a hammer body 1, a fixing hole 2 extending longitudinally through the hammer body 1, a placement hole 3 on the side of the fixing hole 2, the placement hole 3 being placed laterally in the middle of the hammer body 1, a damper 4 being provided in the placement hole 3, and a hammer handle 5 being provided on the side of the damper 4, the hammer handle 5 being fixedly connected to the fixing hole 2; the damper 4 includes a damping block 401, the damping block 401 being slidably connected to the placement hole 3, and pads 402 being provided on both sides of the damping block 401, the pads 402 being slidably connected to the placement hole 3, and springs 403 being provided on the outer sides of the two pads 402 to exert force on the pads 402 towards the damping block 401, the springs 403 being located inside the placement hole 3.

[0024] The hammer body 1 is made of solid steel. The fixing hole 2 is located in the middle of the hammer body 1 and serves as the connection between the hammer body 1 and the hammer handle 5. The upper end of the hammer handle 5 is interference-fitted with the fixing hole 2 to securely install the hammer body 1 and the hammer handle 5. The storage hole 3 is located directly opposite the center of the hammer body 1. The damper 4 inside the storage hole 3 absorbs the recoil force of the hammer body 1, protecting the user's arm during striking. The connection between the hammer handle 5 and the hammer body 1 is a solid structure, ensuring the strength and pressure-bearing capacity of the hammer handle 5 during construction. The damper 4 is located inside the storage hole 3. The damping block 401 inside the damper 4 is a solid cylindrical structure. The damping block 401 can move left and right within the mounting hole. The damping block 401 has pads 402 tightly attached to its left and right sides, and the pads 402 can slide left and right within the mounting hole. Springs 403 are installed on the outer sides of both pads 402. Figure 2 As shown, the spring 403 installed on the left is supported by the hammer body 1, and the spring 403 installed on the right is supported to the left by the hammer handle 5. The two springs 403 have the same elastic coefficient. In the initial state, the two springs 403 press the damping block 401 in the middle of the storage hole 3 through the pad 402. After the hammer body 1 is struck, the hammer body 1 is subjected to a reaction force, and the damping block 401 inside it will swing left and right. The damping block 401 is made of a material with a relatively high density. The contact surface between the pad 402 and the damping block 401 is made of rubber material, which reduces the noise generated between the damping block 401 and the pad 402.

[0025] The upper part of the hammer handle 5 is a solid structure. The lower end of the hammer handle 5 is equipped with a handle support 8. The upper end of the handle support 8 is threadedly connected to the threaded hole 6 through the connecting rod 7. The lower end of the handle support 8 is a hex wrench 10. The size of the hex wrench is smaller than that of the handle support 8. In order to ensure the stability of the connection between the handle support 8 and the hammer handle 5, and to allow the hammer handle 5 to drive the handle support 8 and the hex wrench 10 to rotate, both the handle support 8 and the hammer handle 5 have limit holes. The limit holes are inserted into the limit rod 9. The limit rod 9 restricts the rotation between the handle support 8 and the hammer handle 5. In this way, the hex wrench 10 can be used for operation.

[0026] To improve user comfort, a rubber sleeve 11 is added below the hammer handle 5. The size of the rubber sleeve 11 is the same as the diameter of the handle support 8. This way, there is no protrusion of the hand during use, reducing wear on the hand on the hammer handle 5. The rubber sleeve 11 has anti-slip texture 12. The anti-slip texture 12 and the rubber sleeve 11 increase the friction when the hand is in contact. At the same time, the rubber material has a certain shock absorption effect, which protects the user's arm.

[0027] The depth of the threaded hole 6 within the hammer handle 5 does not exceed the length of the rubber sleeve 11. To improve the functionality of the device, a screwdriver 14 is engaged on the other side of the connecting rod 7 via the first slot 13. In the initial state, the screwdriver 14 and the first connecting rod are located within the threaded hole 6. When the screwdriver 14 is needed for operation, the limiting rod 9 is removed first. Then, the connecting rod 7 is disassembled from the threaded hole 6 via the threaded installation method of the connecting rod 7 and the threaded hole 6. The handle support 8 is reversed, and the hex wrench 10 is inserted into the hexagonal slot 15 for engagement. At this time, the screwdriver 14 outside the connector 1401 faces outward. The hammer handle 5 can be rotated by holding the hammer head 101. The hammer handle 5 can drive the connecting rod 7 and the screwdriver 14 to rotate, thereby achieving the purpose of work. Furthermore, to ensure that there is no interference between the threaded hole 6 and the hexagonal slot 15, the diameter of the threaded hole 6 is equal to the diameter of the inscribed circle of the hexagonal slot 15.

[0028] Furthermore, to improve the overall applicability of the screwdriver 14, the screwdriver 14 has two different sets of connectors at both ends of the internal connector 1401. The wedge connector 1403 is fixedly connected to the connector 1401, and the other end of the connector 1401 is a second slot 1402. The second slot 1402 engages with the Phillips head and is a magnetic slot. The second slot 1402 is detachably connected to the Phillips head 1404. During use, it can be replaced according to the screw type. Users only need to carry different types of Phillips heads 1404.

[0029] The hammer body 1 consists of two parts: a hammer head 101 and a nail puller 102. The hammer head 101 is a cylindrical structure and is used for hammering. The nail puller 102 is a hook-shaped structure. The nail puller groove 103 in the middle of the nail puller 102 is used to hook the nail head. Then, the hammer handle 5 is rotated to pull out the nail using the lever principle.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
