Description

Technical Field

[0001] This utility model relates to the field of precision drilling technology, and in particular to a drilling depth control rod for architectural glass. Background Technology

[0002] With the development of unitized construction technology for building curtain walls and BIM digital construction, in the production and on-site installation of prefabricated components for curtain walls of super high-rise buildings, it is necessary to carry out high-precision positioning and drilling and low-damage processing of special glass such as tempered glass and laminated glass, which requires the use of control rods.

[0003] In practical use, control rods with similar structures still have many defects. For example, traditional handheld electric drills lack guiding devices and rely solely on visual positioning by workers, which is easily affected by hand tremors and causes cumulative errors. At the same time, conventional impact drilling tools release energy instantaneously, which can easily cause micro-cracks to expand. Therefore, it is necessary to design a drilling depth control rod for architectural glass. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a drilling depth control rod for architectural glass.

[0005] This utility model is achieved using the following technical solution: a drilling depth control rod for architectural glass, comprising: an adsorption assembly, wherein the adsorption assembly includes a fixed plate, a movable chamber is provided on the top of the fixed plate, and a first connecting seat is fixedly connected to the outer surface of the movable chamber; and further comprising:

[0006] A drilling assembly, comprising a fixed chamber movably installed inside a movable chamber, wherein a drilling drill is disposed inside the fixed chamber;

[0007] The control assembly includes a main connecting rod rotatably connected to the outer surface of a first connecting seat via a third connecting seat, and an operating handle is provided at the bottom of the main connecting rod via a secondary connecting rod.

[0008] As a further improvement to the above solution, suction plugs are fixedly connected to both sides inside the fixed plate, and a movable chamber is fixedly connected to the top center of the fixed plate.

[0009] Through the above technical solution, this multi-point positioning method effectively solves the stress concentration problem caused by single-point adsorption, prevents thin glass from warping and deforming during drilling, and enhances the adaptability to glass workpieces of different sizes.

[0010] As a further improvement to the above solution, a movable plug is slidably installed inside the movable compartment, and a fixed compartment is fixedly connected to the top of the movable plug.

[0011] Through the above technical solution, the sliding pair formed by the movable plug and the fixed chamber forms a linear motion guide rail, which strictly constrains the rotational motion to axial displacement, avoiding radial displacement caused by hand tremors in traditional hand tools, and significantly improving the hole position accuracy.

[0012] As a further improvement to the above solution, the internal threaded connection of the fixed chamber is provided with a drilling drill, and the top of the fixed chamber is fixedly connected with a second connecting seat.

[0013] Through the above technical solution, the screw drive mechanism transforms rotational motion into precise linear feed, and with the self-locking characteristic of the thread, it achieves micron-level depth control. The operator can judge the drilling progress by sensing the change in torque, and the design depth requirement can be achieved without frequent measurement, thus improving work efficiency.

[0014] As a further improvement to the above solution, a main connecting rod is rotatably connected inside the second connecting seat, and a connecting frame is rotatably connected at the center of the main connecting rod.

[0015] Through the above technical solution, the rotary joint design enables the main connecting rod to transmit axial force and adapt to angular deflection. Together with the connecting frame, it forms a universal joint effect. This flexible transmission system can automatically compensate for tool tilting errors during operation, ensuring that the direction of force is always perpendicular to the glass surface and reducing the risk of edge chipping.

[0016] As a further improvement to the above solution, a third connecting seat is fixedly connected to the bottom of the connecting frame, and the third connecting seat is rotatably connected to the outer surface of the first connecting seat.

[0017] Through the above technical solution, the spatial linkage mechanism constructed by the double rotary joint allows the tool head to automatically adjust its angle according to the direction of the surface normal, enabling it to handle complex architectural components such as curved glass and irregularly shaped curtain walls.

[0018] As a further improvement to the above solution, a secondary connecting rod is fixedly connected to the inner wall of the main connecting rod, and an operating handle is fixedly connected to the outer surface of the secondary connecting rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention utilizes a lever transmission structure consisting of a main connecting rod, a secondary connecting rod, and an operating handle to drive the linear displacement of the fixed chamber along the movable chamber, thereby achieving an efficient conversion of manual force application into precise feeding motion. The four-bar linkage uses the second connecting seat as a fulcrum to amplify and convert the lifting torque applied by the operator to the operating handle into the vertical descent motion of the fixed chamber. The guide rail constraint system formed by the synchronous sliding of the movable plug further limits the radial sway error.

[0021] This invention utilizes the vacuum adsorption force generated by the adsorption plug and the angle compensation mechanism composed of the main connecting rod and the connecting structure to drive the dynamic stability of the glass substrate, thereby achieving a dual protection effect of vibration suppression and damage protection. When the drilling tool contacts the glass surface, the reverse force provided by the adsorption component effectively offsets the axial impact force, while the adaptive adjustment function of the four-bar linkage corrects the tool tilt angle deviation in real time.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5 This embodiment of a drilling depth control rod for architectural glass includes an adsorption assembly 1. The adsorption assembly 1 includes a fixed plate 101, a movable chamber 103 is provided on the top of the fixed plate 101, and a first connecting seat 104 is fixedly connected to the outer surface of the movable chamber 103. It also includes:

[0032] Drilling assembly 2 includes a fixed chamber 202 that is movably installed inside the movable chamber 103, and a drilling drill 203 is provided inside the fixed chamber 202;

[0033] Control component 3 includes a main connecting rod 301 rotatably connected to the outer surface of the first connecting seat 104 via a third connecting seat 305. An operating handle 303 is provided at the bottom of the main connecting rod 301 via a secondary connecting rod 302.

[0034] Adsorption plugs 102 are fixedly connected to both sides inside the fixed plate 101, and a movable chamber 103 is fixedly connected to the center of the top of the fixed plate 101.

[0035] An active plug 201 is slidably installed inside the active compartment 103, and a fixed compartment 202 is fixedly connected to the top of the active plug 201.

[0036] The fixed chamber 202 has an internal threaded connection to a drilling drill 203, and the top of the fixed chamber 202 is fixedly connected to a second connecting seat 204.

[0037] The main connecting rod 301 is rotatably connected inside the second connecting seat 204, and the connecting frame 304 is rotatably connected at the center of the main connecting rod 301.

[0038] A third connecting seat 305 is fixedly connected to the bottom of the connecting bracket 304, and the third connecting seat 305 is rotatably connected to the outer surface of the first connecting seat 104.

[0039] A secondary connecting rod 302 is fixedly connected to the inner wall of the main connecting rod 301, and an operating handle 303 is fixedly connected to the outer surface of the secondary connecting rod 302.

[0040] The operator first holds the operating handle 303, which transmits torque to the main connecting rod 301 through the auxiliary connecting rod 302. Since the top of the main connecting rod 301 is connected to the fixed chamber 202 through the second connecting seat 204, and its bottom is rotatably connected to the first connecting seat 104 through the third connecting seat 305, a lever system is formed with the second connecting seat 204 as the fulcrum. As the operating handle 303 is pulled upward, the main connecting rod 301 rotates around the axis of the second connecting seat 204 and drives the fixed chamber 202 to slide down the inner wall of the movable chamber 103. This design converts manual force application into linear displacement.

[0041] The implementation principle of a drilling depth control rod for architectural glass in this embodiment is as follows: When precise drilling of architectural glass is required, the operator first holds the operating handle 303, and the torque is transmitted to the main connecting rod 301 through the auxiliary connecting rod 302. Since the top of the main connecting rod 301 is connected to the fixed chamber 202 through the second connecting seat 204, and its bottom is rotatably connected to the first connecting seat 104 through the third connecting seat 305, a lever system is formed with the second connecting seat 204 as the fulcrum. As the operating handle 303 is pulled upward, the main connecting rod 301 rotates around the axis of the second connecting seat 204 and drives the fixed chamber 202 to slide down along the inner wall of the movable chamber 103. This design converts manual force application into linear displacement, enabling the fixed chamber 202 and the drilling drill 203 inside to achieve controllable downward movement. The movable plug 201 moves synchronously when the fixed chamber 202 is pressed down, playing a guiding and limiting role to ensure the stability of the movement trajectory.

[0042] After the fixed chamber 202 is lowered to the preset depth, the operator rotates the drilling drill 203. Since the drilling drill 203 is tightly engaged with the fixed chamber 202 through threads, the rotation action can gradually screw it into the glass surface to complete the drilling operation. At the same time, the adsorption plug 102 in the adsorption component 1 is in close contact with the glass substrate to generate vacuum adsorption force, which effectively prevents the glass from shifting due to vibration or impact. This mechanical limiting and adsorption fixation not only improves the drilling positioning accuracy, but also avoids the risk of glass breakage. Throughout the process, the four-bar linkage mechanism composed of the main connecting rod 301 and the connecting frame 304 automatically compensates for the angle deviation, ensuring that the direction of force is always perpendicular to the glass plane, further improving the hole quality.

[0043] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
