Description

Technical Field

[0001] This utility model relates to the field of hand tool technology, and more specifically, to a screwdriver with a level. Background Technology

[0002] Screwdrivers are a commonly used hand tool in many installation and maintenance tasks. However, in practice, many work scenarios not only require tightening or loosening screws but also demand strict levelness of the installed components. For example, when wiring protection cabinets in wind farm substations, improper use of screwdrivers, such as not maintaining a level position or applying force, can lead to tool wear.

[0003] Currently, the common practice for this type of work is to first install the screws using a screwdriver, and then use a separate level to check the levelness of the installed parts. If it is found to be uneven, the position of the parts needs to be readjusted, and the screws need to be tightened or loosened again. This repeated operation not only wastes time and effort, but may also cause wear to the screw holes due to multiple adjustments, affecting the stability of the installation.

[0004] Furthermore, traditional operating methods require operators to carry both a screwdriver and a level, increasing the burden of tool carrying. In confined spaces or complex operating environments, frequent tool changes are extremely inconvenient and reduce work efficiency. Moreover, because there is a time interval and change in operating position between the two operations (tightening screws and checking the level), other factors (such as slight bumps from the operator, ground vibrations, etc.) may cause the originally adjusted parts to change position, thus affecting the final installation result.

[0005] Meanwhile, most existing tools that integrate a level with a screwdriver use a fixed connection. If the level fails, the entire tool may become unusable, resulting in high repair costs. Furthermore, this fixed integration method may affect the structural strength and handling of the screwdriver itself, causing inconvenience to the user. Utility Model Content

Detailed Implementation

[0037] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] like Figures 1-6 The screwdriver shown is equipped with a level indicator. The screwdriver mainly consists of a handle body 1, a level indicator component 6, a visual observation window 3, and a locking adjustment mechanism 4.

[0039] The handle body 1 serves as the grip part of the screwdriver, with a screwdriver shaft 2 connected to one end, which is used to realize the basic function of tightening or loosening screws in a traditional screwdriver.

[0040] The horizontal indicator component 6 is detachably installed inside the handle body 1. This design not only facilitates replacement when the horizontal indicator component 6 is damaged, reducing maintenance costs, but also allows it to be disassembled when the horizontal measurement function is not needed, restoring the screwdriver to its traditional form and ensuring a good operating feel.

[0041] The level indicator component 6 includes a sealed cavity and a position indicator 64 suspended in the fluid medium within the cavity. The sealed cavity prevents fluid leakage and ensures the normal operation of the level indicator component 6. The position change of the position indicator 64 in the fluid medium can intuitively reflect whether the screwdriver is in a level state, providing the user with a levelness reference. Specifically, the level indicator component 6 includes a transparent tubular shell 61, which forms a sealed cavity inside. The transparent design allows the user to observe the state of the position indicator 64 from the outside. The assembly joints 62 at both ends are used to install the level indicator component 6 inside the handle body 1. At least one assembly joint 62 is provided with an assembly positioning structure 67. The assembly positioning structure 67 can be a cross-shaped positioning protrusion. The positioning protrusion matches the positioning slot 51 at the bottom of the mounting groove 5, which helps to accurately position and install the level indicator component 6 inside the handle body 1. Here, the position indicator 64 is an air bubble placed in the fluid medium. Utilizing the characteristic that the air bubble always rises in the fluid medium, when the screwdriver is in a level state, the air bubble is located in a specific position. The user can judge whether the screwdriver is level by observing the position of the air bubble.

[0042] A visual observation window 3 is set on the outer peripheral surface of the handle body 1, corresponding to the position of the horizontal indicator component 6. Through the visual observation window 3, the user can directly observe the status of the position indicator body 64 without disassembling the horizontal indicator component 6, which is convenient and quick to obtain level information. In addition, the surface of the visual observation window 3 is provided with a scale layer 31 containing scales. The scale layer 31 corresponds to the movement trajectory of the position indicator body 64. The scale setting allows the user to more accurately judge the angle of the screwdriver deviating from the horizontal position, thereby adjusting the operation more accurately and improving the accuracy of the work.

[0043] The locking adjustment mechanism 4 includes an axially arranged adjusting member. The axial displacement of the adjusting member enables the installation or removal of the horizontal indicator component 6 within the handle body 1. Specifically, the locking adjustment mechanism 4 includes an adjusting rod with a pressure-bearing part 47 at its front end that rotatably engages with the end of the horizontal indicator component 6. The pressure-bearing part 47 stably pushes or pulls the horizontal indicator component 6 when the adjusting rod moves axially. The rotatable engagement design prevents damage to the horizontal indicator component 6 during operation. An elastic reset component is located inside the adjusting rod and includes a spring element and a sliding guide structure. The spring element provides elastic force, pressing the horizontal indicator component 6 firmly within the handle body 1, preventing a rigid connection between the two. The horizontal indicator component 6 is damaged or not securely fixed; the sliding guide structure ensures the stability and accuracy of the adjusting rod during axial movement. Specifically, the adjusting rod includes a rear rod 43 and a front rod 44. The rear rod 43 is a hollow tube, and one end of the front rod 44 is inserted into the rear rod 43. The end of the front rod 44 is rotatably connected to the pressure bearing part 47. The spring element is set inside the hollow rear rod 43. One end of the spring element is connected and fixed to the top inside the rear rod 43, and the other end is connected and fixed to the end of the front rod 44 that is inserted. The inner wall of the rear rod 43 is provided with a radial positioning groove 45, and the front rod 44 is provided with a protrusion 46 that matches the positioning groove 45. The protrusion 46 and the positioning groove 45 are also in sliding fit.

[0044] The threaded head 42 is located at the rear end of the adjusting rod. It achieves axial displacement adjustment by engaging with the threaded part of the mounting groove 5. By rotating the adjusting rod, the user can achieve axial movement of the adjusting rod by utilizing the interaction between the threaded head 42 and the mounting groove 5, thereby enabling the installation and removal of the horizontal indicator component 6.

[0045] In addition, it also includes an anti-rotation positioning structure that is provided on the pressure-bearing part 47 and the assembly joint 62 to cooperate with each other. It includes the pressure-bearing part 47 and the guide groove 63 provided on the assembly joint 62. The pressure-bearing part 47 and the guide groove 63 can be provided with a structure similar to the positioning protrusion and the positioning slot 51 to ensure that the horizontal indicator component 6 can withstand a large torque when it is installed and locked.

[0046] The transparent tubular housing 61 is fitted with a metal protective sleeve 65. The protective sleeve has a detection window 66 corresponding to the visual observation window 3. The metal protective sleeve 65 can enhance the structural strength of the level indicator component 6, prevent it from being damaged by external impact during use, and extend the service life of the level indicator component 6.

[0047] As a further improvement to this device, the locking adjustment mechanism 4 also includes a top cap 41. A concentric embedding groove 7 is provided at the opening of the mounting groove 5. The diameter of the embedding groove 7 is larger than the diameter of the mounting groove 5. The outer end of the threaded head 42 is provided with a top cap 41. The diameter of the top cap 41 is larger than the diameter of the mounting groove 5 and can be completely embedded in the embedding groove 7. A cutting edge 48 is provided on the outer side of the top cap 41. The threaded engagement is locked in the opening of the mounting groove 5 by the cooperation of other screwdrivers with the threaded end.

[0048] The specific implementation method of this utility model is as follows:

[0049] Installing the horizontal indicator component 6: First, fit the metal protective sleeve 65 onto the outside of the transparent tubular housing 61, ensuring that the detection window 66 corresponds to the position of the transparent tubular housing 61. Then, place the horizontal indicator component 6 at the lower part of the mounting groove 5 inside the handle body 1, so that the positioning protrusion on the assembly joint 62 matches the positioning slot 51 at the bottom of the mounting groove 5, thereby achieving circumferential limiting of the horizontal indicator component 6. Next, rotate the pressure bearing part 47 at the front end of the adjusting rod to engage with the end of the horizontal indicator component 6, so that the pressure bearing part 47 engages with the guide groove 63 on the assembly joint 62, preventing the horizontal indicator component 6 from bearing excessive torque when the adjusting rod rotates. At this time, the elastic reset component is in its natural state. Finally, by rotating the adjusting rod, the threaded head 42 engages with the internal thread of the mounting groove 5, gradually pushing the adjusting rod axially until the horizontal indicator component 6 is securely installed inside the handle body 1.

[0050] Using a screwdriver: Hold the handle body 1 and align the screwdriver shaft 2 with the screw to tighten or loosen it. During operation, observe the position of the bubble through the visual observation window 3. If the bubble is located in the center of the scale layer 31, it means that the screwdriver is in a horizontal position. If the bubble deviates from the center position, adjust the angle of the screwdriver according to the direction of the bubble deviation and the scale layer 31 to bring the bubble back to the center position, ensuring that the parts are in a horizontal position during screw installation or removal.

[0051] Disassembling the horizontal indicator component 6: When it is necessary to disassemble the horizontal indicator component 6, rotate the adjusting rod in the opposite direction so that the threaded head 42 gradually disengages from the internal thread of the positioning slot 51. The adjusting rod moves axially and resets under the action of the elastic reset component. When the adjusting rod moves to a certain position, the horizontal indicator component 6 is no longer locked and can be removed from the mounting slot 5 of the handle body 1 to complete the disassembly.

[0052] Through the above specific implementation methods, the screwdriver with a level of this utility model can efficiently and accurately meet the user's needs for levelness detection during screw operation, and provide convenience for various installation and maintenance work.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
