Description

Technical Field

[0001] The utility model relates to the technical field of electric hammers and electric picks, and relates to the detection function of electric hammers and electric picks, and in particular to an electric hammer and electric pick with external detection equipment. Background Art

[0002] Electric hammers and electric picks are usually power tools used for drilling. Because some walls or floors under construction have buried wires and steel bars, drilling directly with electric hammers or electric picks will have certain safety hazards. In actual operations, the detection of wires and steel bars in walls or floors is usually achieved through wall detectors. However, when some walls or floors are thick, wall detectors may not be able to detect them. During the drilling process, drilling and detecting at the same time will not only increase the difficulty of operation, but also affect the drilling efficiency.

[0003] Some patents, such as the patent application number CN201710894074.8, provide an electric hammer construction equipment with a foldable shoulder support frame, in which the electric hammer can be used for drilling, and the electric hammer is also provided with an infrared rangefinder to detect the depth of the drilling hole.

[0004] However, the electric hammer is not equipped with a metal detection device, which makes it impossible to use the electric hammer to detect metals on walls or floors when drilling. When metal detection on walls or floors is required, detection can only be achieved by replacing the wall detector. When drilling on thick walls or floors, it is also necessary to promptly replace the wall detector or electric hammer for metal detection and drilling construction, which seriously affects the drilling efficiency of the electric hammer.

DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.

[0030] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0031] This embodiment mainly describes an electric hammer and electric pick that is an external detection device that has both metal detection and depth detection functions, as follows:

[0032] like Figure 1-7 As shown, the electric hammer and electric pick of the external detection equipment include a main body, a telescopic rod 2, a metal sensor probe 3 and a metal sensor body 4. The main body 1 is provided with an auxiliary handle 1a and a connecting portion 1b. The telescopic rod 2 is detachably mounted on the auxiliary handle 1a. The telescopic rod 2 is located on one side of the main body 1, and the metal sensor probe 3 is mounted on the telescopic rod 2. The metal sensor probe 3 is located at the front end of the telescopic rod 2, and the metal sensor body 4 is detachably mounted on the connecting portion 1b. The metal sensor body 4 is located at the top of the main body 1, and a connecting signal line 5 is provided between the metal sensor body 4 and the metal sensor probe 3.

[0033] Preferably, the metal sensor body 4 has the functions of signal amplification and alarm.

[0034] By setting the metal sensor probe 3 on the telescopic rod 2 and installing the telescopic rod 2 and the metal sensor body 4 on the main body 1, the electric hammer and electric pick can perform metal detection on the wall or ground that needs to be drilled.

[0035] like Figure 3-7 As shown, in this embodiment, the telescopic rod 2 includes a front section 2a, a rear section 2b, a compression spring 2c and a plug 2d, wherein the front section 2a and the rear section 2b are both tubular structures, the outer diameter of the front section 2a is smaller than the outer diameter of the rear section 2b, the front section 2a is inserted into the rear section 2b for installation, the compression spring 2c is arranged in the rear section 2b, and the plug 2d is threadedly installed at the tail end of the rear section 2b, the compression spring 2c is located between the front section 2a and the plug 2d, and the compression spring 2c elastically supports the front section 2a.

[0036] The metal sensor probe 3 is threadedly installed at the front end of the front section 2a, and the signal line 5 connecting the metal sensor probe 3 passes through the front section 2a and the rear section 2b, and passes through the plug 2d to connect to the metal sensor body 4, and the compression spring 2c located in the rear section 2b is wound outside the signal line 5.

[0037] In order to prevent the front section 2a from being separated from the rear section 2b by the action of the compression spring 2c, a limiting portion 2a1 is provided at the tail end of the front section 2a, and a limiting sleeve 2b1 is provided at the front end of the rear section 2b. The limiting portion 2a1 and the limiting sleeve 2b1 are in a structure that is small in the front and large in the back. The front section 2a is inserted into the rear section 2b from the tail end of the rear section 2b and passes through the rear section 2b. The limiting portion 2a1 of the front section 2a and the limiting sleeve 2b1 of the rear section 2b cooperate to limit the front section 2a from being separated from the front end of the rear section 2b, and the compression spring 2c is also inserted from the tail end of the rear section 2b. The plug 2d is threadedly installed at the tail end of the rear section 2b, which can limit the compression spring 2c and the front section 2a from falling out of the tail end of the rear section 2b.

[0038] Two depth markings 2a2 are provided on the front section 2a, and the value of one depth marking 2a2 increases from front to back, and the value 0 is the front end of the metal sensor probe 3, which can be used to read the hole depth when the telescopic rod 2 is inserted into the hole drilled by the electric hammer and pick. The value of the other depth marking 2a2 increases from front to back, and the value 0 is the front end of the rear section 2b of the telescopic rod 2. When the electric hammer and pick are drilling, the depth of the drilled hole can be detected in time, so that the electric hammer and pick have the function of depth detection while having the function of metal detection, which diversifies the additional functions of the electric hammer and pick, and effectively improves the safety and work efficiency of the electric hammer and pick when drilling.

[0039] like Figure 5-7 As shown, the auxiliary handle 1a is provided with a mounting portion 1a1, and the mounting portion 1a1 is located on one side of the main body 1. The mounting portion 1a1 is provided with an insertion cavity 1a2, and the insertion cavity 1a2 is provided with an opening, and an insertion block 6 is provided to be inserted into the insertion cavity 1a2. The insertion cavity 1a2 is provided with a socket 1 1a3 that passes through the front and back, and the insertion block 6 is provided with a socket 2 62. The insertion block 6 is inserted into the insertion cavity 1a2, and the rear end of the telescopic rod 2 is inserted into the socket 1 1a3 and the socket 2 62 for installation.

[0040] To ensure that the plug block 6 can limit the rear section 2b from separating from the socket 1a3 and the socket 2 62, a mounting hole 61 with a lower opening is provided at the lower end of the plug block 6, and a spring 7 is provided in the mounting hole 61. The spring 7 contacts the bottom of the cavity 1a2 and elastically supports the plug block 6, so that misalignment can occur between the socket 1a3 and the socket 2 62. The hole walls of the socket 1a3 and the socket 2 62 clamp the rear section 2b, increase the friction between the rear section 2b and the hole walls of the socket 1a3 and the socket 2 62, and limit the sliding of the rear section 2b in the socket 1a3 and the socket 2 62, that is, limit the sliding of the rear section 2b relative to the mounting portion 1a1 and the plug block 6.

[0041] Because the plug block 6 can move up and down in the insertion cavity 1a2, when the rear section 2b of the telescopic rod 2 is detached from the plug block 6 and the mounting portion 1a1, in order to avoid the plug block 6 from being lost, the plug block 6 can be detachably installed in the insertion cavity 1a2. In this embodiment, a hook hole 1a4 is opened on the cavity wall behind the insertion cavity 1a2, and the hook hole 1a4 is connected to the plug hole 1a3 on the cavity wall of the insertion cavity 1a2, and an elastic hook 63 that can cooperate with the hook hole 1a4 is provided on the plug block 6. The elastic hook 63 is hooked in the hook hole 1a4 to limit the plug block 6 from being separated from the insertion cavity 1a2.

[0042] like Figure 6 As shown, a connecting portion 1b with a T-shaped or dovetail structure is provided above the main body 1, and a sliding sleeve 8 is provided which is slidably installed on the connecting portion 1b. The metal sensor body 4 is fixedly connected to the sliding sleeve 8 by screws 11, and a limiting member 9 and a spring 10 are installed between the sliding sleeve 8 and the metal sensor body 4. The spring 10 elastically supports the limiting member 9 to extend from the lower end of the sliding sleeve 8. A plurality of limiting grooves 1b1 distributed front and back are provided on the end surface of the connecting portion 1b, and the limiting member 9 can be inserted into a limiting groove 1b1 to limit the sliding of the sliding sleeve 8.

[0043] Preferably, the notch of the limit groove 1b1 and the lower end of the limit member 9 are chamfered to facilitate the pushing action of the sliding sleeve 8 relative to the connecting portion 1b. The chamfered cooperation between the limit member 9 and the limit groove 1b1 can cause the limit member 9 to move upward and out of the limit groove 1b1, thereby realizing the sliding of the sliding sleeve 8 relative to the connecting portion 1b.
