Description

Technical Field

[0001] This utility model relates to the field of soldering iron tip technology, and in particular to a durable rotary soldering iron tip. Background Technology

[0002] Soldering tip is a key consumable component of soldering equipment such as soldering irons and soldering stations, and is widely used in soldering electronic components. Because different electronic components have different soldering positions and shapes, the soldering tip angle needs frequent adjustment to ensure soldering accuracy. However, traditional soldering tips are often fixed to the handle, making angle adjustment difficult. This not only increases the difficulty of operation but may also lead to a decrease in soldering quality due to improper soldering angles.

[0003] According to a rotary soldering iron tip rotation drive unit with announcement number CN217529549U, the soldering iron tip angle is adjusted by driving a clamping plate to clamp a fixed plate via a bidirectional lead screw: rotating the rotating block drives the bidirectional lead screw to rotate, causing the clamping plate to move along the slide bar to loosen or tighten the fixed plate, thereby realizing the rotation and locking of the soldering iron tip. However, this solution has the following shortcomings: The clamping force between the clamping plate and the fixed plate depends on the thread accuracy of the double-acting screw. After long-term use, thread wear can easily cause the clamping plate to loosen. Moreover, the anti-slip texture design can only alleviate surface slippage and cannot solve the problem of decreased axial positioning accuracy.

[0004] Therefore, we propose a durable rotary soldering tip. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. The clamping force between the clamping plate and the fixed plate depends on the thread accuracy of the bidirectional lead screw. After long-term use, thread wear can easily lead to loosening of the clamping plate. Furthermore, the anti-slip texture design can only alleviate surface slippage and cannot solve the problem of decreased axial positioning accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A durable rotary soldering iron tip includes a hollow shell with an internal cavity; a soldering iron tip body installed inside the cavity of the hollow shell; and a rotating assembly that passes through the soldering iron tip body and is connected to the inner wall of the hollow shell for driving the soldering iron tip body to rotate and achieve angle adjustment. A drive rotation mechanism is disposed inside the cavity of the hollow shell and connected to the rotation assembly. It is used to drive the rotation assembly to rotate. It includes a connecting part, a driving part, and a locking part. The driving part is connected to the connecting part and is used to drive the connecting part to rotate. The connecting part is connected to the rotation assembly, thereby driving the rotation assembly to rotate and adjust. The locking part is connected to the connecting part by plugging and unplugging, thereby limiting and fixing the connecting part.

[0007] As a preferred embodiment of this utility model, the rotating assembly includes: A rotating rod, which passes through the soldering iron tip body and is connected at both ends to the hollow shell; The first gear is fixedly mounted on the rotating rod.

[0008] As a preferred embodiment of this utility model, the connecting portion includes: A rotating shaft is disposed within the receiving cavity of the hollow shell, and its two ends are connected to the hollow shell; The turbine is fixedly installed at the center of the rotating shaft, and several locking holes are equidistantly arranged around its side wall; The second gear is fixedly mounted on the rotating shaft and meshes with the first gear.

[0009] As a preferred embodiment of this utility model, the driving unit includes: The worm gear is located inside the hollow housing and meshes with the turbine. A rotating cap is fixedly connected to one end of the worm gear, and the rotating cap is located on the outside of the hollow shell for hand rotation.

[0010] As a preferred embodiment of this utility model, the locking part includes: The mounting bracket is fixedly installed inside the hollow shell, and its outer side has an arc surface that matches the curvature of the receiving cavity of the hollow shell. A locking rod is inserted inside the mounting bracket and is used to insert into the locking hole to lock the locking hole.

[0011] As a preferred embodiment of this utility model, the locking part further includes: The mounting plate is fixedly connected to the plug-in locking rod; A compression spring is fitted at both ends onto the plug-in locking rod and the mounting bracket, respectively. The compression spring is compressed or extended as the mounting plate moves. The pull cap is fixedly installed at one end of the plug-in locking rod and is used to pull the plug-in locking rod to move it.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the rotating assembly is driven by the meshing transmission of a worm and a turbine, replacing the method of using a bidirectional lead screw to drive the clamping plate in the prior art. This avoids the wear problem of the threads after long-term use. The drive unit adopts a reduction transmission structure of a worm and a turbine. The small-amplitude rotation of the rotating cap can be converted into a fine rotation of the soldering iron tip body through gear meshing, and it has a self-locking characteristic. At the same time, the locking rod of the locking part is directly inserted into the locking hole on the side wall of the turbine to form a rigid lock. Compared with the friction locking of the clamping plate and the fixed plate, it can effectively prevent axial displacement, avoid accidental contact with the rotating cap and damage to the soldering iron tip body, and improve the positioning stability after angle adjustment.

[0013] The mounting bracket of the locking part fits against the inner wall of the hollow housing, and the plug-in locking rod achieves automatic reset through compression spring, avoiding the linear friction loss between the clamping plate and the slide rod in the comparison document. At the same time, the gear transmission structure of the rotating component adopts rigid meshing, which can reduce the generation of metal chips and extend the service life of the drive mechanism compared with the contact transmission of the clamping plate clamping the fixed plate.

However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a durable rotary soldering iron tip, including a hollow shell 10, the hollow shell 10 having an internal cavity; a soldering iron tip body 20, installed inside the cavity of the hollow shell 10; and a rotating assembly 30, penetrating the soldering iron tip body 20 and connected to the inner wall of the hollow shell 10, for driving the soldering iron tip body 20 to rotate, thereby adjusting the angle. The drive rotation mechanism 40 is disposed inside the cavity of the hollow housing 10 and connected to the rotation assembly 30. It is used to drive the rotation assembly 30 to rotate. It includes a connecting part, a driving part and a locking part. The driving part is connected to the connecting part and is used to drive the connecting part to rotate. The connecting part is connected to the rotation assembly 30 and thus drives the rotation assembly 30 to rotate and adjust. The locking part is connected to the connecting part by plugging and unplugging and thus limits and fixes the connecting part.

[0021] When the angle of the soldering iron tip body 20 needs to be adjusted, the drive unit drives the rotating component 30 to rotate through the connecting part. The rotating component 30 passes through the soldering iron tip body 20 and drives it to rotate. The locking part cooperates with the connecting part through a plug-in method. When the angle is adjusted to the correct position, the locking part is inserted into the connecting part to fix it and prevent the soldering iron tip body 20 from shaking. This structure replaces the method of clamping the clamping plate by driving the bidirectional lead screw in the comparative document through the transmission and locking of the drive rotating mechanism 40. It uses the worm gear meshing and rigid locking hole structure to avoid thread wear and improve locking reliability.

[0022] Rotating assembly 30 includes: Rotating rod 301 passes through soldering iron tip body 20 and is connected to hollow shell 10 at both ends; The first gear 302 is fixedly installed at the rotating rod 301.

[0023] The rotating rod 301 serves as the rotation axis of the soldering iron tip body 20, passing through its interior and connected to the hollow housing 10 via a bearing to ensure smooth rotation. The first gear 302 is fixed on the rotating rod 301 and meshes with the second gear 404 in the drive rotation mechanism 40. When the second gear 404 rotates, it drives the first gear 302 to rotate through gear transmission, thereby driving the rotating rod 301 and the soldering iron tip body 20 to rotate. This gear transmission structure adopts rigid meshing, which, compared with the friction transmission between the clamp and the fixed plate in the comparison document, can reduce the generation of metal chips and extend the service life.

[0024] The connecting part includes: A rotating shaft 401 is disposed inside the receiving cavity of the hollow shell 10, and its two ends are connected to the hollow shell 10. The turbine 402 is fixedly installed at the center of the rotating shaft 401, and a number of locking holes 403 are equidistantly arranged around its side wall; The second gear 404 is fixedly mounted on the rotating shaft 401 and meshes with the first gear 302.

[0025] The rotating shaft 401 is fixed inside the hollow housing 10 by bearings, serving as the transmission core of the connecting part. The turbine 402 and the second gear 404 are both fixed on the rotating shaft 401. When the worm 406 of the drive part rotates, the worm 406 meshes with the turbine 402, driving the rotating shaft 401 to rotate. Then, through the meshing of the second gear 404 with the first gear 302, the power is transmitted to the rotating assembly 30. The locking hole 403 on the side wall of the turbine 402 cooperates with the insertion locking rod 408 of the locking part. When the angle is adjusted to the correct position, the insertion locking rod 408 is inserted into the locking hole 403 to form a rigid lock, preventing the rotating shaft 401 from moving accidentally due to external force, thus solving the problem of easy loosening of the clamping plate in the comparison document.

[0026] The drive unit includes: The worm gear 406 is disposed inside the hollow housing 10 and meshes with the turbine 402; The rotating cap 405 is fixedly connected to one end of the worm gear 406, and the rotating cap 405 is located on the outside of the hollow housing 10 for hand rotation.

[0027] The rotating cap 405 is exposed on the outside of the hollow shell 10. When the operator rotates the rotating cap 405, it drives the worm gear 406 to rotate synchronously. The worm gear 406 meshes with the turbine gear 402. Due to the deceleration characteristics of the worm gear drive, the small-amplitude rotation of the rotating cap 405 can be converted into the slow rotation of the turbine gear 402. This, in turn, drives the soldering iron tip body 20 to finely adjust the angle through the rotating shaft 401 and the second gear 404. At the same time, the self-locking characteristic of the worm gear drive allows the soldering iron tip body 20 to automatically maintain its position after adjustment without the need for additional manual locking. Compared with the operation of repeatedly rotating the rotating block to control the opening and closing of the clamp in the comparison document, the adjustment efficiency and accuracy are significantly improved.

[0028] The locking mechanism includes: Mounting bracket 407 is fixedly installed inside the hollow shell 10, and its outer side is provided with an arc surface, which is consistent with the curvature of the receiving cavity of the hollow shell 10. A locking rod 408 is inserted inside the mounting bracket 407 and is used to insert into the locking hole 403 to lock the locking hole 403.

[0029] Mounting bracket 407 is fixed to the inner wall of hollow housing 10 with screws. Its arc surface is consistent with the arc of the housing to ensure installation stability. The plug-in locking rod 408 passes through mounting bracket 407. When the angle needs to be adjusted, the operator pulls the plug-in locking rod 408 outward to disengage it from the locking hole 403 of turbine 402. At this time, the drive unit can rotate freely. When the angle is adjusted to the correct position, the plug-in locking rod 408 is released. Under the action of compression spring 410, it automatically inserts into the adjacent locking hole 403 to form a rigid limit. This structure replaces the friction locking between the clamp and the fixed plate in the comparison document with a plug-in locking, avoiding axial displacement. Moreover, the arc surface design of mounting bracket 407 fits the hollow housing 10, reducing sliding friction loss and improving structural durability.

[0030] The locking mechanism also includes: Mounting plate 409 is fixedly connected to plug-in locking rod 408; Compression spring 410, with its two ends respectively sleeved on the plug-in locking rod 408 and the mounting bracket 407, compresses or extends as the mounting plate 409 moves; Pull cap 411 is fixedly installed at one end of plug-in locking rod 408 and is used to pull plug-in locking rod 408 to move.

[0031] Pull cap 411 is exposed on the outside of hollow housing 10. The operator pulls pull cap 411 to move plug-in locking rod 408. Mounting plate 409 moves with plug-in locking rod 408 and compresses compression spring 410, causing plug-in locking rod 408 to disengage from locking hole 403. When pull cap 411 is released, compression spring 410 returns to its original position and pushes mounting plate 409, causing plug-in locking rod 408 to automatically insert into locking hole 403. The setting of compression spring 410 ensures automatic reset of plug-in locking rod 408, avoiding linear frictional wear between clamp and slide bar in comparison file. At the same time, the cooperation between rigid locking hole 403 and plug-in locking rod 408 can precisely control the rotation angle of soldering tip body 20, such as fixed angle corresponding to each hole, to achieve graded locking.

[0032] This durable rotary soldering iron tip achieves angle adjustment and locking through the coordinated transmission of the drive rotation mechanism 40 and the rotation assembly 30. The specific working principle is as follows: I. Power transmission path for angle adjustment Drive unit start-up: The operator rotates the rotating cap 405 on the outside of the hollow housing 10, which drives the worm gear 406 to rotate.

[0033] Worm gear reducer transmission: The worm 406 meshes with the worm gear 402. Due to the reduction characteristics of the worm gear, the small-amplitude rotation of the rotating cap 405 is converted into the slow rotation of the worm gear 402.

[0034] Gear meshing transmission: The turbine 402 is fixed on the rotating shaft 401, which drives the rotating shaft 401 to rotate. Then, through the second gear 404, it meshes with the first gear 302 of the rotating assembly 30 to transmit power to the rotating rod 301.

[0035] Soldering iron tip body rotation: Rotating rod 301 passes through soldering iron tip body 20 and drives it to rotate around the axis to achieve angle adjustment.

[0036] II. Working Logic of the Locking Mechanism Unlocked state: Pulling the locking cap 411 of the locking part causes the plug-in locking rod 408 to move outward, the compression spring 410 is compressed, and the plug-in locking rod 408 disengages from the locking hole 403 on the side wall of the turbine 402. At this time, the drive part can rotate freely.

[0037] Locked state: After adjusting to the target angle, release the pull cap 411, the compression spring 410 returns to its original position and pushes the mounting plate 409, so that the plug-in locking rod 408 automatically inserts into the adjacent locking hole 403, forming a rigid limit to prevent the turbine 402 and the rotating shaft 401 from moving accidentally.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
