Description

Technical Field

[0001] This utility model belongs to the field of drilling device technology, and more specifically, it relates to a drilling device for slender holes. Background Technology

[0002] When drilling holes in walls or wood, drilling equipment is often required. The existing drilling equipment is generally a drill gun. Since many walls or wood are quite thick, when it is necessary to drill through holes in thick wood or walls, it is generally necessary to install a thin drill bit on the drill gun to perform the drilling operation.

[0003] The existing application number is CN202123226611.2. This utility model discloses a drilling device for burying a geophone in hard ground conditions. It includes a drill gun, a detachable connecting device at the left end of the drill gun, a level on the right end of the outer wall of the drill gun, a rotating device on the left end of the connecting device, a guide device at both ends inside the connecting device, and a limiting device at both ends inside the guide device. The rotating device is a slender conical drill bit, which is located at the left end of the connecting device. This utility model uses the rotating device to drill a hole in the ice surface and then bury the geophone, so that the geophone is completely fitted with the drill hole, thereby increasing the accuracy of the geophone data detection.

[0004] Based on the above, when drilling long and narrow holes in wood or walls, the operator usually pushes the drill gun forward. However, often the operator's forward pushing force is too great, causing the drill bit to drill too fast, which can easily cause the drill bit to shake and damage it. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a drilling device for elongated holes, which solves the problem that when drilling elongated holes in wood or walls, the operator usually squeezes the drill gun forward. However, often the operator's forward squeezing force is too large, causing the drill bit to drill too fast, which can easily cause the drill bit to shake and damage it.

[0006] The purpose and effect of this utility model for a drilling device for slender holes are achieved by the following specific technical means:

[0007] A drilling device for elongated holes includes a drill gun body, a long drill bit, a drilling limiter, a drilling protective cover, a drilling drive box, a drilling drive handwheel, a drilling display mechanism, and a drilling auxiliary mechanism.

[0008] The long drill bit is mounted at the front end of the drill gun body;

[0009] The drilling limiting component is fixedly connected to the top of the drill gun body, and the drilling limiting component is provided with a sliding groove structure;

[0010] The drill bit protective cover is installed at the front end of the drill bit body;

[0011] The drilling drive box is fixedly connected to the rear right side of the drilling limiter.

[0012] The drilling drive handwheel is rotatably connected to the upper end of the drilling drive box;

[0013] The drilling display mechanism is positioned above the drilling limiter.

[0014] The drilling auxiliary mechanism is located on the outside of the drilling limiter.

[0015] Furthermore, the drilling display mechanism includes: a vertical display element;

[0016] The vertical display component is fixedly connected above the drilling limit component, and the vertical display component is a semi-circular structure with scale.

[0017] Furthermore, the drilling display mechanism also includes: a display pointer and a display counterweight;

[0018] The display pointer is rotatably connected to the left side of the vertical display component;

[0019] The display counterweight is fixedly connected to the lower end of the display pointer.

[0020] Furthermore, the drilling auxiliary mechanism includes: a drilling drive rack and a drilling drive gear;

[0021] The drilling drive rack is slidably connected inside the groove of the drilling limiter, and the front end of the drilling drive rack is fixedly connected to the drilling protective cover.

[0022] The drilling drive gear is rotatably connected to the inner rear end of the drilling limiter, and the drilling drive gear meshes with the drilling drive rack.

[0023] Furthermore, the drilling auxiliary mechanism also includes: a drilling drive worm and a drilling drive worm wheel;

[0024] The drilling drive worm is rotatably connected inside the drilling drive box, and the drilling drive worm is coaxially and fixedly connected to the lower end of the drilling drive handwheel.

[0025] The drilling drive worm gear is rotatably connected inside the drilling drive box. The drilling drive worm gear meshes with the drilling drive worm, and the drilling drive worm gear is coaxially and fixedly connected with the drilling drive gear.

[0026] Furthermore, the drilling auxiliary mechanism also includes: a dustproof connecting plate and a dustproof connecting spring;

[0027] Two sets of dustproof connecting plates are provided, and the two sets of dustproof connecting plates are slidably connected to the left and right sides of the drilling protective cover respectively;

[0028] Two sets of dustproof connecting springs are provided. The two sets of dustproof connecting springs are fixedly connected to the upper left and right sides of the drilling protective cover, and the outer sides of the two sets of dustproof connecting springs are fixedly connected to the dustproof connecting plate.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] This utility model, through the setting of a drilling display mechanism, causes the display counterweight and the vertical display component to rotate relative to each other when the drilling limit component tilts vertically. The rotation of the display counterweight drives the display pointer to rotate, which in turn causes the scale indicated by the display pointer to change, thus reminding the operator and preventing the drilling from going astray, thereby ensuring the quality of the drilling.

[0031] This invention, through the design of a drilling auxiliary mechanism, achieves dust protection during the drilling process with a drilling protective cover. When drilling, rotating the drilling drive handwheel causes the drilling drive worm to rotate, which in turn drives the drilling drive worm wheel, which in turn drives the drilling drive gear. This movement of the drilling drive gear then moves the drilling drive rack backward, which in turn moves the drilling protective cover backward. This allows for slow, forward drilling, preventing damage to the long drill bit caused by forceful forward pressure during drilling. It protects the long drill bit from shaking during drilling, ensuring stable drilling and allowing the user to operate the drill gun with both hands, thus improving drilling safety. After drilling is complete, pressing the dustproof connecting plates inward seals the drilling protective cover, allowing for the collection of drilled dust. Attached Figure Description

[0039] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0040] Example 1: As shown in the attached document Figure 1 To be continued Figure 4 As shown:

[0041] This utility model provides a drilling device for slender holes, including a drill gun body 1, a long drill bit 2, a drilling limiter 3, a drilling protective cover 4, a drilling drive box 5, a drilling drive handwheel 6, and a drilling display mechanism.

[0042] The long drill bit 2 is installed at the front end of the drill gun body 1;

[0043] The drilling limiter 3 is fixedly connected to the top of the drill gun body 1, and the drilling limiter 3 is provided with a sliding groove structure;

[0044] The drill bit protective cover 4 is installed at the front end of the drill bit body 1;

[0045] The drilling drive box 5 is fixedly connected to the rear right side of the drilling limiter 3;

[0046] The drilling drive handwheel 6 is rotatably connected to the upper end of the drilling drive box 5;

[0047] The drilling indicator mechanism is located above the drilling limiter 3.

[0048] The drilling display mechanism includes: a vertical display component 101, a display pointer 102, and a display counterweight 103;

[0049] The vertical display component 101 is fixedly connected above the drilling limit component 3. The vertical display component 101 is a semi-circular structure with scale.

[0050] The pointer 102 is rotatably connected to the left side of the vertical display 101;

[0051] The counterweight 103 is fixedly connected to the lower end of the display pointer 102.

[0052] During use, when drilling, if the drilling limiter 3 tilts vertically, the display counterweight 103 and the vertical display 101 will rotate relative to each other. The rotation of the display counterweight 103 will cause the display pointer 102 to rotate, and the rotation of the display pointer 102 will cause the scale indicated by the display pointer 102 to change, thus reminding the operator and preventing the drilling from going astray, ensuring the quality of the drilling.

[0053] Example 2: This utility model provides a drilling device for elongated holes, based on Example 1, such as... Figures 1 to 5 As shown, it also includes a drilling auxiliary mechanism, which is located on the outside of the drilling limit member 3.

[0054] The drilling auxiliary mechanism includes: a drilling drive rack 601, a drilling drive gear 602, a drilling drive worm 603, a drilling drive worm wheel 604, a dustproof connecting plate 605, and a dustproof connecting spring 606.

[0055] The drilling drive rack 601 is slidably connected inside the groove of the drilling limiter 3, and the front end of the drilling drive rack 601 is fixedly connected to the drilling protective cover 4.

[0056] The drilling drive gear 602 is rotatably connected to the inner rear end of the drilling limit member 3, and the drilling drive gear 602 meshes with the drilling drive rack 601.

[0057] The drilling drive worm 603 is rotatably connected inside the drilling drive box 5, and the drilling drive worm 603 is coaxially fixedly connected to the lower end of the drilling drive handwheel 6;

[0058] The drilling drive worm gear 604 is rotatably connected inside the drilling drive box 5. The drilling drive worm gear 604 meshes with the drilling drive worm 603 and is coaxially and fixedly connected with the drilling drive gear 602.

The two sets of dustproof connecting springs 606 are fixedly connected to the upper left and right sides of the drilling protective cover 4, respectively. The outer sides of the two sets of dustproof connecting springs 606 are fixedly connected to the dustproof connecting plate 605.

[0061] During use, when drilling is required, the drill guard 4 provides dust protection during the drilling process. When drilling begins, rotating the drill drive handwheel 6 rotates the drill drive worm 603, which in turn rotates the drill drive worm wheel 604. The worm wheel 604 then rotates the drill drive gear 602, which in turn moves the drill drive rack 601 backward, thus driving the drill... The borehole protective cover 4 moves backward, enabling slow forward drilling. This prevents the user from pressing forward forcefully during drilling, which could damage the long drill bit 2. It protects the long drill bit 2 and prevents it from shaking during drilling, ensuring stable drilling. At the same time, it allows the user to operate the drill gun with both hands, improving drilling safety. After drilling is completed, the dustproof connecting plate 605 is pressed inward. At this time, the two sets of dustproof connecting plates 605 seal the borehole protective cover 4, thereby collecting the drilled dust.
