Description

Technical Field

[0001] This utility model relates to the field of spark plug mounting technology, and in particular to a quick-release engine spark plug mounting system. Background Technology

[0002] The spark plug holder is a connecting structure mounted on the engine block, used for precise positioning and secure fixing of the spark plug. Its main function is to ensure strict alignment between the spark plug and the ignition hole in the cylinder block, while reliably pressing it against the mounting surface using mechanical structures such as threads and clips, forming a good airtight seal and electrical connection. During engine operation, the spark plug holder must withstand the impact of high-temperature, high-pressure gases, as well as high-frequency vibration and thermal expansion and contraction. Therefore, its structural precision and assembly efficiency directly affect the engine's operational stability and ease of maintenance.

[0003] However, existing spark plugs often require the use of extension tools or magnetic pull ropes to remove them from the cylinder block. This process is cumbersome, time-consuming, and labor-intensive, and is prone to problems such as jamming or falling. This not only increases the difficulty of maintenance but also affects the efficiency and safety of spark plug replacement, making it difficult to meet the needs of efficient and convenient engine maintenance. Utility Model Content

[0004] Therefore, it is necessary to address the issue that existing spark plugs often require the use of extension tools or magnetic pull ropes to remove them from the cylinder block, resulting in a cumbersome, time-consuming, and labor-intensive process. Furthermore, problems such as jamming or dropping can easily occur, increasing maintenance difficulty and affecting the efficiency and safety of spark plug replacement, failing to meet the needs of efficient and convenient engine maintenance. To address this, a quick-release engine spark plug holder is provided, comprising: a holder with multiple spark plugs arranged on one side; and a telescopic access mechanism for facilitating spark plug removal and disassembly, disposed on one side of the holder. The access mechanism includes multiple mounting seats fixedly installed on the surface of the holder, each mounting seat containing a quick-release assembly, and a mounting assembly on the top of each mounting seat.

[0005] The quick-release assembly includes a drive ring disposed inside the mounting base. The drive ring is sleeved on the outside of the spark plug, and one side of the drive ring abuts against the spark plug. A spring is fixedly installed at the bottom of the drive ring, and the other end of the spring is fixedly connected to the mounting base.

[0006] A telescopic sleeve is fixedly installed at the bottom of the drive ring, the spring is located inside the telescopic sleeve, and the other end of the telescopic sleeve is fixedly connected to the inner wall of the mounting base.

[0007] A retaining frame is fixedly installed on the top of the drive ring. The retaining frame is cylindrical and is located on the outside of the spark plug.

[0008] A fixing ring is fixedly installed on the top of the mounting base, and the mounting component is disposed on one side of the fixing ring.

[0009] The mounting assembly includes a fixing cap disposed on the top of the spark plug, a limiting block being fixedly mounted on the surface of the fixing cap, and an inlet being provided on the inner ring surface of the fixing ring.

[0010] The inner ring surface of the fixed ring is provided with a movable groove. One side of the movable groove is connected to the inlet, and the other side of the movable groove is connected to a limiting groove. The limiting groove is provided on the inner ring surface of the fixed ring.

[0011] A pull rod is fixedly installed on the top of the fixed cover, and a gap is provided between the bottom of the pull rod and the fixed cover.

[0012] Beneficial effects

[0013] 1. The installation assembly enables quick installation and precise positioning of the spark plug, ensuring its stability on the mounting bracket. The quick-release assembly allows the spark plug to be automatically ejected during removal, eliminating the need for additional tools, simplifying the maintenance process and improving repair efficiency;

[0014] 2. After the limiting block enters the movable groove through the inlet, the operator can rotate the fixed cover 90 degrees to move the limiting block along the movable groove to the bottom of the limiting groove. At this time, the spring-driven clamping frame pushes the fixed cover upward, causing the limiting block to lock into the limiting groove, thus achieving a stable lock on the fixed cover and spark plug.

[0028] The following is combined Figures 1-5 This invention describes a quick-release engine spark plug holder.

[0029] In one embodiment, a quick-release engine spark plug holder includes: a holder 100, on one side of which a plurality of spark plugs 200 are disposed; and a service mechanism 300, a telescopic service mechanism 300 disposed on one side of the holder 100 for facilitating the removal and disassembly of the spark plugs 200; wherein the service mechanism 300 includes a plurality of mounting seats 310 fixedly mounted on the surface of the holder 100, each of the mounting seats 310 having a quick-release assembly 320 inside, and a mounting assembly 330 being disposed on the top of the mounting seat 310.

[0030] In this embodiment, the installation component 330 enables the spark plug 200 to be quickly installed and precisely positioned, allowing the spark plug 200 to be easily assembled onto the mounting base 100, ensuring the stability of the spark plug 200 during operation. The quick-release component 320 allows the spark plug 200 to be automatically ejected during disassembly, making it easy to remove the spark plug 200 without the need for additional tools. This simplifies the maintenance process, improves maintenance efficiency, and reduces the difficulty of operation and the risk of misoperation.

[0031] It should be noted that the existing spark plug 200 mounting base 100 typically includes basic components such as the body structure for mounting the spark plug 200, threaded holes or positioning holes, sealing gaskets, and related fastening structures. These components work together to ensure that the spark plug 200 can reliably connect to the engine block, achieving functions such as precise positioning, sealing, and conductivity, thus meeting the performance requirements of the ignition system for normal engine operation.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, the quick-release assembly 320 includes a drive ring 321 disposed inside the mounting base 310. The drive ring 321 is sleeved on the outside of the spark plug 200, and one side of the drive ring 321 abuts against the spark plug 200. A spring 323 is fixedly installed at the bottom of the drive ring 321, and the other end of the spring 323 is fixedly connected to the mounting base 310.

[0033] In this embodiment, when the mounting assembly 330 is removed, the spring 323 can push the drive ring 321 to move upward along the axial direction, thereby automatically ejecting the spark plug 200 from the mounting seat 310, achieving quick removal of the spark plug 200. This structure not only simplifies the disassembly operation of the spark plug 200, but also allows the ejection and removal process to be completed without the need for external tools.

[0034] A telescopic sleeve 322 is fixedly installed at the bottom of the drive ring 321, and a spring 323 is located inside the telescopic sleeve 322. The other end of the telescopic sleeve 322 is fixedly connected to the inner wall of the mounting base 310.

[0035] In this embodiment, a telescopic sleeve 322 is fixedly installed at the bottom of the drive ring 321, and a spring 323 is disposed inside the telescopic sleeve 322. The other end of the telescopic sleeve 322 is fixedly connected to the inner wall of the mounting base 310. The telescopic sleeve 322 can effectively protect the spring 323, preventing the spring 323 from being affected by external dust, impurities, or lubricating oil during compression or extension.

[0036] A retaining frame 324 is fixedly installed on the top of the drive ring 321. The retaining frame 324 is cylindrical and is located on the outside of the spark plug 200.

[0037] In this embodiment, the clamping frame 324 can form a surface contact fit with the mounting component 330 during the installation process, thereby applying uniform axial pressure to the mounting component 330 and effectively enhancing the fixing stability of the mounting component 330.

[0038] A retaining ring 325 is fixedly mounted on the top of the mounting base 310, and the mounting assembly 330 is disposed on one side of the retaining ring 325.

[0039] In this embodiment, the retaining ring 325 can cooperate with the mounting component 330 to effectively limit and press the spark plug 200, ensuring that the spark plug 200 always maintains a stable installation state during use.

[0040] like Figure 2 , Figure 3 and Figure 5 As shown, the mounting assembly 330 includes a fixing cover 331 disposed on the top of the spark plug 200, a limiting block 332 fixedly mounted on the surface of the fixing cover 331, and an inlet 333 opened on the inner ring surface of the fixing ring 325.

[0041] In this embodiment, the fixing cover 331 inserts and fixes the limiting block 332 through the inlet 333, and at the same time tightens and fixes the spark plug 200.

[0042] The inner ring surface of the fixed ring 325 is provided with a movable groove 334. One side of the movable groove 334 is connected to the inlet 333, and the other side of the movable groove 334 is connected to a limiting groove 335. The limiting groove 335 is provided on the inner ring surface of the fixed ring 325.

[0043] In this embodiment, after the limiting block 332 enters the movable groove 334 through the inlet 333, the operator can rotate the fixed cover 331 ninety degrees, causing the limiting block 332 to move along the movable groove 334 to below the limiting groove 335. At this time, the spring 323 drives the abutment frame 324 to push the fixed cover 331 upward, causing the limiting block 332 to engage in the limiting groove 335, thus achieving a stable lock on the fixed cover 331 and the spark plug 200.

[0044] A pull rod 336 is fixedly installed on the top of the fixed cover 331, and a gap is provided between the bottom of the pull rod 336 and the fixed cover 331.

[0045] In this embodiment, the lateral layout of the pull rod 336 facilitates the lifting and rotation of the fixed cover 331 by the operator within a limited space. When it is necessary to remove or install the spark plug 200, the operator can lift or rotate the fixed cover 331 and unlock or lock the limiting block 332 by pulling or rotating the pull rod 336, which greatly improves the convenience and safety of assembly and disassembly.

[0046] Working principle: During normal operation, the mounting base 100 is used to install and secure multiple spark plugs 200. Each spark plug 200 is sequentially inserted into multiple mounting seats 310 on one side of the mounting base 100. Each mounting seat 310 has a mounting component 330 on its top. The mounting component 330, through structures such as the fixing cover 331 and the limiting block 332, precisely limits and presses the spark plug 200, ensuring that the spark plug 200 is stably assembled on the mounting base 100, meeting the positioning, sealing, and conductivity requirements for engine ignition. During maintenance, the operator can easily lift and rotate the fixing cover 331 in a space-constrained environment using the horizontally arranged pull rod 336 to lock and unlock the limiting block 332. The limiting block 332 is inserted into the movable groove 334 of the fixing ring 325 through the inlet 333. After rotating the fixing cover 331 ninety degrees, the limiting block 332 enters the limiting groove 335 and is driven by the spring 323 to push the clamping frame 324 upward to achieve locking. When removing the spark plug 200, after removing the mounting assembly 330, the spring 323 in the quick-release assembly 320 releases its elastic force, pushing the drive ring 321 and the clamping frame 324 on its top to move upward along the axis, thereby automatically pushing the spark plug 200 out of the mounting seat 310. It can be easily removed without external tools. The spring 323 is located inside the telescopic sleeve 322, which protects it from external impurities and ensures that the spring 323 moves smoothly and reliably.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
