Description

Technical Field

[0001] The present invention relates to a hammer for electric power equipment construction, and particularly to an electrician's snow-melting hammer. Background Art

[0002] During the construction and maintenance of electric power, such as the installation and repair of outdoor distribution boxes, electric power cabinets and other electric power equipment, it is necessary to strike the electric power equipment. When the existing electrician's hammer strikes on the electrical equipment covered with snow, it only has the function of a hammer and cannot accelerate the melting of the snow on the electrical striking part. In addition, when performing the above installation and maintenance on the existing electric power equipment, a hammer head and a shovel are usually carried at the same time to meet different requirements. The separate existence of multiple tools is likely to cause the phenomenon that it is not easy to find in time if one is forgotten to carry or lost. Moreover, the cutting edge of the shovel is exposed when not in use, and the safety is poor. Summary of the Invention

[0003] The first object of the present invention is to provide an electrician's snow-melting hammer that can sprinkle salt when striking an electrical appliance to promote snow melting, and solves the problem that the hammer used in the existing electric power construction cannot accelerate the melting of snow on the electrical equipment.

[0004] The second object of the present invention is to further provide an electrician's snow-melting hammer with a shovel rod that can shovel the surface of an object to remove dirt and the cutting edge of the shovel can be accommodated when not in use, and solves the problems that it is easy to lose or miss one of them when carrying an independent hammer and a shovel during the existing electric power construction and the cutting edge of the shovel is in a long-term exposed state with poor safety.

[0005] The following technical problems are solved by the following technical solutions: An electric snow hammer includes a hammer body and a handle connected to the hammer body. One end of the hammer body is provided with a hammer head. The characteristic is that a sliding cavity is provided in the hammer body, and the extending direction of the sliding cavity intersects with the extending direction of the handle. A stepped surface is formed between the hammer head and the end surface of the hammer head. A partition board is hermetically and slidably connected in the sliding cavity. The partition board divides the sliding cavity into a salt storage cavity and an oscillator moving cavity. A salt outlet hole communicating with the salt storage cavity is provided on the stepped surface. A salt adding hole communicating with the salt storage cavity is provided on the hammer body. A plug is provided in the salt adding hole. An oscillator is provided in the oscillator moving cavity. The oscillator is connected to the partition board through a compression spring. A partition board moving spring for driving the partition board to press on the salt in the salt storage cavity so that the salt storage cavity is kept filled with the salt in the salt storage cavity is provided in the hammer head. A sliding hole is provided on the side wall of the salt outlet hole. A salt outlet hole closing valve plate is provided in the sliding hole. A valve plate closing spring for driving the salt outlet hole closing valve plate to extend out of the sliding hole to close the salt outlet hole is provided in the sliding hole. A driving inclined surface is provided between the end surface of the valve plate away from the sliding hole and the surface of the valve plate facing the salt storage cavity. When in use, salt is stored in the salt storage cavity. When the hammer is struck, when the hammer strikes an electrical device and stops, the oscillator still moves towards the direction where the salt storage cavity is located under the action of inertia, compresses the compression spring and drives the partition board to push the salt. The salt generates a force to push out the salt outlet hole closing valve plate. Under the guidance of the driving inclined surface, the salt outlet hole closing valve plate squeezes the valve plate closing spring to open the valve plate. The salt is scattered from the salt outlet hole onto the snow on the electrical appliance, playing a role in melting the snow. When the oscillator stops moving forward due to inertia, the valve plate is closed again under the action of the valve plate closing spring. Under the action of the compression spring, the oscillator resets so that there is a moving space for the oscillator during the next strike, and the inertia of the oscillator is used to push the partition board to squeeze out the salt..

[0006] Preferably, when the valve plate closes the salt outlet hole, the driving inclined surface extends into the sliding hole. This can make it more reliable to squeeze open the valve plate when flowing towards the salt outlet hole..

[0007] Preferably, a resistance reducing inclined surface is provided between the end surface of the valve plate away from the sliding hole and the surface of the valve plate away from the salt storage cavity. This can not only make the force required for the valve plate to close small, but also enable the valve plate to occupy a larger space in the salt outlet hole when it extends so that the salt can be discharged more fully. If the valve plate is designed as a triangular pointed head composed only of a driving inclined surface, it can also achieve that the force required for the valve plate to close is small, but at this time, the extension of the valve plate cannot play a role in discharging more salt in the salt outlet hole.

[0008] Preferably, the oscillator is slidably connected in the sliding cavity, and the oscillator is provided with a flow channel communicating with the spaces at both ends of the oscillator storage cavity. This can avoid the radial shaking of the oscillator.

[0009] Preferably, a guiding hole is provided at one end of the sliding cavity away from the isolation plate. The isolation plate is connected with a guiding rod passing through the guiding hole. The isolation plate moving spring is located in the guiding hole, and the isolation plate moving spring drives the isolation plate through the guiding rod, which has better reliability during operation.

[0010] Preferably, the compression spring is sleeved on the guiding rod.

[0011] Preferably, the other end of the hammer body is detachably connected with an end cap. A shovel rod with a pointed head is hinged on the end cap. Limiting grooves distributed along the circumferential direction of the hammer head are provided on the surface of the hammer head, and the pointed head is inserted into the limiting grooves. When used as a hammer for knocking, hold the handle and use the hammer head to knock. When shoveling something, remove the end cap so that the shovel rod is not restricted by the limiting grooves, and then shovel the object with the pointed head of the shovel rod, achieving the second invention purpose.

[0012] Preferably, there are at least three shovel rods. The three shovel rods are distributed along the circumferential direction of the hammer body, and the widths of the shovel rods along the circumferential direction of the pituitary body are different from each other, which can meet the requirements of shoveling with shovel rods of different widths.

[0013] Preferably, when the pointed heads of all the shovel rods are inserted into the limiting grooves, the shovel rods form an annular body covering the pituitary body, which has a compact structure.

[0014] Preferably, there are 6 shovel rods, and the central angles corresponding to the radial cross-sections of the six shovel rods are 5 degrees, 25 degrees, 45 degrees, 60 degrees, 90 degrees and 135 degrees respectively.

[0015] Preferably, the pointed head of the shovel rod with a central angle of 5 degrees is formed by the intersection of two planes, and the pointed heads of the other shovel rods are formed by the intersection of a cylindrical surface and a conical surface, which can meet the requirements for different shovel head structures.

[0016] Preferably, the end cap is threadedly connected with the pituitary body, with fewer components.

[0017] Preferably, the side surface of the limiting groove along the outer end of the diameter of the pituitary body is a conical surface, and the side surface of the limiting groove along the outer end of the diameter of the pituitary body intersects with the outer surface of the pituitary body to form a cutting edge, which can be used to scrape an object through the cutting edge to achieve surface peeling.

[0018] Preferably, a receiving hole is provided on the end surface of the end of the pituitary body connected with the end cap, which can hold an insulating tape in the receiving hole for carrying. The function is expanded, and the load capacity of the toolbox can be improved.

[0019] Preferably, the pituitary includes a head section and a tail section. The hammer head is disposed at one end of the head section, and a connection hole is provided at the other end of the head section. A tapered surface section is provided at one end of the connection hole away from the hammer head. One end of the tail section is inserted into the connection hole, and the other end is connected to the end cap. A limiting groove is defined between the tail section and the tapered surface section.

[0020] Preferably, the head section and the tail section are detachably connected together by bolts. After removing the tail section, the connection hole of the head section can be used to punch holes in the insulating paper.

[0021] The present invention has the following beneficial effects: When hitting an electrical appliance, salt can be scattered to accelerate the melting of ice along the electrical appliance; the shovel is integrated on the hammer, with a compact structure; as long as one of them is carried or both are carried, and as long as one of them is lost, it is equivalent to losing both, so that it can be timely discovered whether there is a shortage or loss; the joint of the shovel rod used as a shovel is accommodated in the limiting groove, which can not only prevent the sharp tip from being exposed when not in use, resulting in insecurity, but also prevent the shovel rod from swinging when used as a hammer for hitting, interfering with the use; the shovel rod can play a role in increasing the weight of the hammer, so that when the weight requirement of the hammer is certain, the weight of the pituitary can be reduced.

A driving inclined surface 23 is provided between the end surface of the valve plate far from the sliding hole and the surface of the valve plate facing the salt storage cavity. When the valve plate closes the salt outlet hole, the driving inclined surface extends into the sliding hole. A resistance reducing inclined surface 24 is provided between the end surface of the valve plate far from the sliding hole and the surface of the valve plate far from the salt storage cavity. A salt adding hole 25 communicating with the salt storage cavity is provided on the hammer body. A plug 26 is provided inside the salt adding hole. The plug is threadedly connected inside the salt adding hole. A guiding hole 27 is provided at one end of the sliding cavity far from the partition plate. A guiding rod 31 passing through the guiding hole is connected to the partition plate. A partition plate moving spring is provided inside the guiding hole. The partition plate moving spring drives the partition plate through the guiding rod. The partition plate moving spring is used to drive the partition plate to press on the salt in the salt storage cavity so that the salt in the salt storage cavity is in a filled state. An oscillator 32 is provided inside the oscillator moving cavity. The oscillator is slidably connected inside the sliding cavity. The oscillator is provided with a flow channel 28 communicating with the spaces at both ends of the oscillator storage cavity.

[0028] At the other end of the first section, a connection hole 6 is provided. A conical surface section 7 is provided at one end of the connection hole far from the hammer head. The tail section is a circular tubular structure. One end of the tail section is inserted into the connection hole. The first section and the tail section are detachably connected together by a bolt 8. A limiting groove 9 is formed between the tail section and the conical surface section. The side surface of the limiting groove along the outer end of the pituitary body diameter (i.e., the inner surface of the conical surface section) intersects with the outer surface of the pituitary body to form a cutting edge 10. The internal space of the tail section constitutes a receiving hole 11. A end cap 12 is threadedly connected to the other end of the tail section. Six shovel rods 13 are hinged to the end cap.

The pointed head of the shovel rod 14 with a central angle of 5 degrees is formed by the intersection of two planes. The pointed heads of the other shovel rods are formed by the intersection of a cylindrical surface and a conical surface.

[0029] The process of salting in this invention is as follows: Salt is stored in the salt storage cavity. When it is struck with a hammer, when the hammer hits the electrical equipment and stops, the oscillator still moves towards the direction of the salt storage cavity under the action of inertia, compresses the compression spring and drives the isolation plate to push the salt. The salt generates a force to push out the closing valve plate of the salt outlet hole. Under the guidance of the driving inclined surface, the closing valve plate of the salt outlet hole squeezes the valve plate closing spring to open the valve plate, and the salt is scattered from the salt outlet hole onto the snow on the electrical appliance to play the role of melting the snow. When the oscillator stops moving forward due to inertia, the valve plate closes again under the action of the valve plate closing spring. Under the action of the compression spring, the oscillator resets to provide space for the oscillator to move during the next strike, so as to utilize the inertia of the oscillator to push the isolation plate to extrude the salt.
