Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof hammers, in particular to an explosion-proof and shock-proof hammer. Background Art

[0002] When performing some operations such as hitting in flammable and explosive places such as oil, natural gas, oil pipelines, and natural gas pipelines, it is extremely easy to generate sparks, which may lead to explosion. Therefore, in such occasions, people often use explosion-proof hammers. The explosion-proof hammer is the most important explosion-proof tool for hitting in various flammable and explosive places. The existing explosion-proof hammer head is solid, and a large vibration will be generated at the moment of hitting. The vibration will be transmitted to the worker's arm along the hammer handle. The arms of workers engaged in long-term hitting operations are likely to be injured by the vibration of the explosion-proof hammer. Content of the Utility Model

[0003] The purpose of the utility model is to avoid the deficiencies of the prior art and provide an explosion-proof and shock-proof hammer, thereby effectively solving the deficiencies existing in the prior art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: an explosion-proof and shock-proof hammer, including a hammer head and a hammer handle. The hammer head includes a cylindrical hammer body and hammer caps arranged at the upper and lower ends of the hammer body. The hammer body is filled with shock-proof sand.

[0005] Further, a support rod is axially arranged in the hammer body. The support rod is supported between the two hammer caps, and the support rod is connected to the hammer body through a connecting rod.

[0006] Further, four connecting rods are evenly arranged in the circumferential direction of the support rod.

[0007] Further, rubber pads are arranged at both ends of the support rod.

[0008] Further, the hammer head is screwed on the hammer handle, and a locking mechanism for preventing the hammer head from rotating is arranged on the hammer handle.

[0009] Further, the locking mechanism includes a sliding sleeve axially movably arranged on the hammer handle. A plurality of clamping protrusions are arranged on the front side of the sliding sleeve in the circumferential direction, and a plurality of clamping grooves are arranged on the hammer head to cooperate with the clamping protrusions.

[0010] Further, the cross-section of the part of the hammer handle that cooperates with the sliding sleeve is square.

[0011] Further, a stop edge is arranged on the hammer handle at the rear side of the sliding sleeve, and an elastic member is arranged between the sliding sleeve and the stop edge.

[0012] The above technical solution of the present utility model has the following beneficial effects: The present utility model is provided with a hollow hammer head, and shock-proof sand is filled in the hammer body. When the explosion-proof hammer is about to vibrate and rebound after hitting, the shock-proof sand in the hammer body falls and applies a downward pressure to the hammer head, generating resistance to the rebound of the hammer head, thereby reducing the vibration when the explosion-proof hammer hits and reducing the harm to workers.

[0017] The following describes the preferred embodiments of the present utility model in detail in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0018] In the description of the present utility model, unless otherwise specified, "a plurality of" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model. In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] Such as Figure 1-2As shown in the figure, an explosion-proof and shock-proof hammer according to this embodiment includes a hammer head 1 and a hammer handle 2. The hammer head 1 includes a cylindrical hammer body 3 and hammer caps 4 provided at the upper and lower ends of the hammer body 3. The hammer body 3 is filled with shock-proof sand. When the explosion-proof hammer is about to vibrate and rebound after being struck, the shock-proof sand in the hammer body 3 falls and exerts a downward pressure on the hammer head 1, generating resistance to the rebound of the hammer head 1, thereby reducing the vibration when the explosion-proof hammer strikes and reducing the harm to the worker.

[0020] Preferably, a support rod 5 is axially arranged in the hammer body 3. The support rod 5 is supported between the two hammer caps 4. The support rod 5 is connected to the hammer body 3 through a connecting rod 6. The support rod 5 can support the hammer cap 4 and enhance the strength of the hammer cap 4 during hammering.

[0021] Preferably, four connecting rods 6 are evenly arranged in the circumferential direction of the support rod 5. The shock-proof sand in the hammer body 3 can pass between the connecting rods 6. The uniform arrangement of the four connecting rods 6 can balance the force on the connecting rods 6.

[0022] Preferably, rubber pads 7 are provided at both ends of the support rod 5. When the hammer cap 4 is installed, the hammer cap 4 compresses the rubber pads 7 and then is installed on the hammer body 3.

[0023] Preferably, the hammer head 1 is screwed onto the hammer handle 2. A locking mechanism for preventing the hammer head 1 from rotating is provided on the hammer handle 2. When the whole hammer head 1 needs to be replaced, a new hammer head 1 can be screwed onto the hammer handle 2, and then the locking mechanism is used to prevent the hammer head 1 from rotating, avoiding the hammer head 1 from detaching from the hammer handle 2.

[0024] Preferably, the locking mechanism includes a sliding sleeve 8 that is axially movable on the hammer handle 2. A plurality of clamping protrusions 9 are arranged in the circumferential direction on the front side of the sliding sleeve 8. A plurality of clamping grooves 10 are provided on the hammer head 1 to cooperate with the clamping protrusions 9. After the hammer head 1 is installed on the hammer handle 2, the sliding sleeve 8 is moved so that the clamping protrusions 9 are inserted into the clamping grooves 10, thereby restricting the rotation of the hammer head 1.

[0025] Preferably, the cross-section of the part of the hammer handle 2 that cooperates with the sliding sleeve 8 is square. The sliding sleeve 8 and the hammer handle 2 are cooperated through the square cross-section to restrict rotation.

[0026] Preferably, a stop edge 11 is provided on the hammer handle 2 at the rear side of the sliding sleeve 8. An elastic member 12 is provided between the sliding sleeve 8 and the stop edge 11. The elastic member 12 is a spring. The spring drives the sliding sleeve 8 to approach the hammer head 1, so that the clamping protrusions 9 can be kept inserted into the clamping grooves 10.
