Description

Technical Field

[0001] This invention relates to a multifunctional cover, belonging to the field of connection structure technology, a mechanism that can be connected, fixed, and quickly disassembled, and relates to the structural technology of end face connection of cylindrical products. Background Technology

[0002] Traditional end-face connection methods have many shortcomings. Common structures include... Figure 1 As shown, it mainly includes a cover sleeve (1), a cylinder (2), and a protective cover (3); the protective cover (3) is directly glued to the cylinder (2), making it impossible to disassemble and inconvenient to maintain or inspect the inside of the cylinder. The cover sleeve (1) and the cylinder (2) are connected by a thread, which requires multiple turns during assembly and disassembly, which is time-consuming, laborious, and inconvenient. In addition, in order to prevent the product from being dropped or damaged by impact, a rubber sleeve (1a) is usually additionally pressed into the end face of the metal cover sleeve (1), which increases the number of parts and manufacturing processes, and increases the cost.

[0003] Therefore, there is an urgent need for an end-face connection mechanism that can integrate locking, fixing, and protection functions and enable rapid assembly and disassembly, in order to solve the problems of complex structure, low assembly and disassembly efficiency, and numerous protection procedures in existing technologies. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cylindrical product end cover mechanism that is simple in structure, highly integrated, can be quickly locked and disassembled, and has good anti-drop and anti-vibration performance.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] A multifunctional cover, with an improved structure as follows: Figure 2 As shown, it includes a brake lever (4), a spring (5), a multi-functional cover (6), a cylinder (2), and a sealing ring (7).

[0007] The multifunctional cover (3) is an integrated component, with a protective cover (6a) fixedly wrapped around its exterior as a protective layer, and a cover sleeve (6b) with a connecting and locking structure inside. The cover sleeve (6b) has an annular sealing groove for installing a sealing ring [7] on its inner side, and its outer side is designed to be able to be inserted into the end of the cylinder (2).

[0008] The brake lever (4) extends through the center or side of the multifunctional cover (6), and its lower end can be inserted into or removed from the corresponding locking hole or slot provided on the cover sleeve (6b). The spring [5] is sleeved on the brake lever (4) and acts between the brake lever (4) and the multifunctional cover (6), providing the brake lever (4) with a return force toward the locked position.

[0009] Its working principle is as follows:

[0010] Installation and locking process: First, insert the sealing ring (7) into the sealing groove of the cover sleeve (6b). Then, pull the brake rod (4) upward, causing the compressed spring (5) to move upward to the unlock position (at this time, the lower end of the brake rod retracts). Next, align the multi-functional cover (6) with and cover the end face of the cylinder (2). Finally, release the brake rod (4), the compressed spring (5) returns to its original position, and drives the brake rod (4) downward, so that its lower end is inserted into the locking position formed by the corresponding hole groove on the cover sleeve (6b) and the cylinder (2), thereby realizing the fixed locking of the cover and the cylinder.

[0011] Quick disassembly process: When disassembly is required, simply pull the brake lever (4) upwards to compress the spring again [5], so that the lower end of the brake lever (4) is completely pulled out from the locked position. At this time, the mechanical lock between the multi-functional cover (6) and the cylinder (2) is released, and the multi-functional cover (6) can be directly removed from the cylinder (2) to complete the quick disassembly.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. High integration and simplified structure: The functions of the original independent protective cover (3) and cover sleeve (6b) are integrated into a multi-functional cover (6), merging the three parts into one, which significantly reduces the number of parts and assembly steps.

[0014] 2. Easy to operate and quick to assemble and disassemble: Locking can be completed with a simple "pull-release" action, and disassembly only requires a single pull action. Compared with the traditional threaded screw method, it greatly improves the efficiency of assembly and disassembly.

[0015] 3. Comprehensive functions: This single part simultaneously achieves multiple functions such as end face sealing and fixing, mechanical locking, quick disassembly, and drop protection and vibration protection through the external protective cover (6a).

[0016] 4. High reliability: The spring-driven brake lever locking mechanism has a stable locking force and is not easy to loosen in a vibration environment. At the same time, the sealing ring ensures the sealing of the connection. Attached Figure Description

[0018] Figure 2 This is a cross-sectional schematic diagram of an improved structure of a multifunctional cover. Detailed Implementation

[0019] The following is in conjunction with the appendix Figure 2 The preferred embodiments of the present invention will be described in further detail below.

[0020] The quick locking and unlocking cover mechanism of this embodiment consists of a brake rod (4), a spring (5), a multi-functional cover (6), a cylinder (2), and an O-ring (7).

[0021] The multifunctional cover (6) is integrally injection molded from engineering plastic, and its exterior is entirely covered with a soft rubber layer as a protective cover (6a). The cover sleeve (6b) is stepped, with the small-diameter section inserted into the port of the cylinder (2) and the large-diameter section fastened to the end face of the port. A pair of radial through-holes are opened in the middle of the small-diameter section, and a pair of radial holes are also opened at the corresponding positions on the cylinder (2).

[0022] The brake lever (4) is a stepped shaft with an operating head at the top and a locking pin at the bottom. The brake lever (4) passes vertically through the guide hole at the top of the multi-functional cover (6). A compression spring (5) is fitted in the middle of the brake lever (4), with its upper end pressing against the inside of the operating head and its lower end pressing against the inner stepped surface of the cover sleeve (6b).

[0023] The multifunctional cover (6) includes an outer protective cover (6a) and an inner cover sleeve (6b), the cover sleeve (6b) being used to insert into the end of the cylinder (2);

[0024] The brake lever (4) is movably mounted on the multifunctional cover (6) and can move between a first position and a second position. When it is in the first position, its lower end is inserted into and locked between the cover sleeve (6b) and the cylinder (2), so that the multifunctional cover (6) and the cylinder (2) are fixedly connected. When it is in the second position, its lower end is disengaged from the locking position.

[0025] The spring (5) acts between the brake lever (4) and the multifunctional cover (6), providing the brake lever (4) with an elastic force that tends it toward the first position.

[0026] The inner side of the cover sleeve (6b) is provided with a sealing groove for installing a sealing ring (7).

[0027] The external protective cover (6a) is an elastic material layer fixed to the cover sleeve (6b) by bonding or overmolding.

[0028] The lower end of the brake lever (4) is a locking pin, and the cover sleeve (6b) and the cylinder (2) are respectively provided with locking holes or slots for the locking pin to be inserted; the spring (5) is a compression spring sleeved on the brake lever (4).

[0029] During assembly, first place the O-ring (7) into the annular sealing groove of the small diameter section of the cover sleeve (6b). When installing the cover, lift the operating head of the brake lever (4) upwards to compress the spring (5), so that the lower locking pin is raised to be completely above the locking hole of the multi-functional cover (6). Then insert the multi-functional cover (6) into the port of the cylinder (2) until the stepped surface of the cover sleeve (6b) is in contact with the end face of the cylinder. At this time, release the brake lever (4), and under the restoring force of the compression spring (5), the brake lever (4) moves down, and the locking pin at its lower part passes through the locking hole of the cover sleeve (6b) and the corresponding hole on the cylinder (2) in sequence, like a "pin" to rigidly lock the two, completing the installation.

[0030] During disassembly, simply pull up the brake lever (4) again to disengage the locking pin from the hole in the cylinder (2), and the entire multi-functional cover (6) can be easily pulled out.

[0031] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
