Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and more specifically, to a combined circular telescopic protective cover. Background Technology

[0002] Circular telescopic covers are important protective devices used in the industrial field to protect mechanical parts. They have a circular cross-section and can elastically expand and contract. Their core functions include dustproof, waterproof, oilproof, and protection against emulsion and chemical corrosion. They also have properties such as high temperature resistance and aging resistance.

[0003] Currently, when circular telescopic covers protect mechanical components such as lead screws and guide rails, both ends need to be fixed to the mechanical components with bolts. The cover body then expands and contracts with the movement of the mechanical components to prevent external impurities from affecting their operation. However, when the length of the circular telescopic cover is insufficient, existing circular telescopic covers need to be connected with bolts to extend the cover length. Bolted circular telescopic covers are not only inconvenient, but also prone to loosening at the bolt joints after long-term use, resulting in poor stability. Therefore, this utility model proposes a combined circular telescopic cover. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a combined circular telescopic cover, which aims to solve the problem that when the length of the existing circular telescopic cover is insufficient, it needs to be connected by bolts to extend the length of the cover. Bolting the circular telescopic cover is not only inconvenient, but also prone to loosening and poor stability at the bolt connection point after long-term use.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A combined circular telescopic protective cover includes multiple circular protective covers, which are detachably connected and coaxially arranged. Each circular protective cover has end connection holes at both ends, and multiple buckle assemblies are provided between each pair of adjacent circular protective covers.

[0009] Each of the aforementioned buckle assemblies includes a first fixing block, a connecting fastener, a second fixing block, a push rod, a plug, two telescopic locking blocks, and a spring. The first fixing block and the second fixing block are respectively fixedly connected to two adjacent circular protective covers. The connecting fastener is rotatably connected to the first fixing block. The push rod is slidably inserted into the second fixing block. The plug is fixedly connected to one end of the push rod, and the plug corresponds to the connecting fastener. The two telescopic locking blocks are slidably connected into the plug, and the ends of the two telescopic locking blocks that are far apart extend to the symmetrical sides of the plug. The spring is disposed in the plug and is located between the two telescopic locking blocks.

[0010] As a preferred embodiment of this utility model, the connector is provided with a limiting groove, and the two telescopic blocks are fixedly connected to limiting sliders, and the two limiting sliders are slidably connected in the limiting groove.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) In this solution, the combined circular telescopic cover can be combined with multiple circular protective covers through multiple buckle components. The multiple buckle components are more efficient in disassembly and assembly than bolt connections. After connection, it is not easy to loosen. It can quickly combine multiple circular protective covers to meet the usage requirements of mechanical parts of different lengths. Moreover, the second fixing block, push rod and plug in the buckle component are located inside the circular protective cover. The connecting fastener can also rotate to the inside of the circular protective cover on the first fixing block. It will not affect the connection of the two farthest circular protective covers to the mechanical parts through the two end connection hole groups. It does not hinder the installation of multiple circular protective covers on the mechanical parts, and it can quickly combine and connect multiple circular protective covers.

[0017] (2) In this scheme, multiple circular protective covers are integrally formed by casting. The surface of the directly cast circular protective covers has no welding points.

[0027] Example:

[0028] Please see Figure 1-4 A combined circular telescopic protective cover includes multiple circular protective covers 1, which are detachably connected and coaxially arranged. Each circular protective cover 1 has end connection hole groups 2 at both ends, and multiple buckle assemblies are provided between each pair of adjacent circular protective covers 1.

[0029] Each buckle assembly includes a first fixing block 3, a connecting fastener 4, a second fixing block 5, a push rod 6, a plug connector 7, two telescopic locking blocks 8, and a spring 9. The first fixing block 3 and the second fixing block 5 are respectively fixedly connected to two adjacent circular protective covers 1. The connecting fastener 4 is rotatably connected to the first fixing block 3. The push rod 6 is slidably inserted into the second fixing block 5. The plug connector 7 is fixedly connected to one end of the push rod 6, and the plug connector 7 corresponds to the connecting fastener 4. The two telescopic locking blocks 8 are slidably connected into the plug connector 7, and the ends of the two telescopic locking blocks 8 that are far apart extend to the symmetrical sides of the plug connector 7. The spring 9 is disposed in the plug connector 7, and the spring 9 is located between the two telescopic locking blocks 8.

[0030] In this embodiment, when the length of the circular telescopic protective cover is insufficient, multiple circular protective covers 1 are selected and combined according to the required length. Each pair of adjacent circular protective covers 1 are connected by multiple snap-fit ​​components. By rotating the connecting fastener 4 of each snap-fit ​​component, the connecting fastener 4 rotates on the first fixing block 3 to correspond with the plug 7. Then, the push rod 6 is pushed to slide in the second fixing block 5, so that the plug 7 is inserted into the connecting fastener 4. During the insertion of the plug 7, the two telescopic locking blocks 8 are retracted by force and the spring 9 is compressed. When the end of the plug 7 passes through the connecting fastener 4, the two telescopic locking blocks 8 follow the plug 7 through to one side of the connecting fastener 4. The spring 9 causes the two telescopic locking blocks 8 to pop out from the plug 7, so that the plug 7 and the connecting fastener 4 form a snap-fit, thereby combining two adjacent circular protective covers 1 to adapt to different usage lengths. After the multiple circular protective covers 1 are combined, the ends of the two outermost circular protective covers 1 that are far apart are respectively installed on the mechanical parts through the end connecting hole group 2 and bolts, so that the multiple circular protective covers 1 can provide telescopic protection for the mechanical parts.

[0031] Specifically, the connector 7 has a limiting groove 11, and the two telescopic blocks 8 are fixedly connected to limiting sliders 12, and the two limiting sliders 12 are slidably connected in the limiting groove 11.

[0032] In this embodiment, the two telescopic blocks 8 will drive the two limiting sliders 12 to slide within the limiting groove 11 respectively. The two limiting sliders 12 and the limiting groove 11 can restrict the sliding of the two telescopic blocks 8 and prevent the two telescopic blocks 8 from falling out of the connector 7.

[0033] Specifically, each of the two telescopic blocks 8 has a positioning port 13 at one end that is close to the other, and the two ends of the spring 9 are located in the two positioning ports 13 respectively.

[0034] In this embodiment, the two positioning ports 13 are used to position the spring 9, so that the spring 9 can perform stable elastic work between the two telescopic blocks 8.

[0035] Specifically, each circular protective cover 1 is integrally formed by casting.

[0036] In this embodiment, multiple circular protective covers 1 are integrally formed by casting. The surface of the directly cast circular protective cover 1 is seamless, has high strength, and is not easy to crack.

[0037] Specifically, each circular protective cover 1 is fixedly connected with multiple limiting blocks 10, and the multiple limiting blocks 10 correspond to multiple connecting fasteners 4 respectively.

[0038] In this embodiment, the limiting block 10 is used to restrict the rotation of the connecting fastener 4 so that the connecting fastener 4 can be accurately inserted into the connector 7 after rotation.

[0039] Working principle: When the length of the circular telescopic protective cover is insufficient, multiple circular protective covers 1 are selected and combined according to the required length. Each pair of adjacent circular protective covers 1 is connected by multiple buckle assemblies. By rotating the connecting fastener 4 of each buckle assembly, the connecting fastener 4 rotates on the first fixed block 3 to correspond with the plug 7. Then, the push rod 6 is pushed to slide in the second fixed block 5, so that the plug 7 is inserted into the connecting fastener 4. During the insertion of the plug 7, the two telescopic locking blocks 8 are forced to retract and compress the spring 9. When the end of the plug 7 passes through the connecting fastener 4, the two telescopic locking blocks 8 follow the plug 7 through to one side of the connecting fastener 4. The spring 9 causes the two telescopic locking blocks 8 to pop out from the plug 7, so that the plug 7 and the connecting fastener are connected. A snap-fit ​​is formed between 4, and at the same time, the second fixing block 5 restricts the push rod 6 from continuing to push. With the restriction of the two telescopic blocks 8 on the side of the connecting fastener 4, the two adjacent circular protective covers 1 can be stably combined to adapt to different usage lengths. After the multiple circular protective covers 1 are combined, the ends of the two outermost circular protective covers 1 that are far apart are respectively installed on the mechanical parts through the end connecting hole group 2 with bolts, so that the multiple circular protective covers 1 can extend and retract to protect the mechanical parts. When the multiple circular protective covers 1 need to be disassembled, the two telescopic blocks 8 are pressed to retract into the connector 7, the restriction on the connector 7 is removed, and the connector 7 is pulled out from the connecting fastener 4, thereby realizing the quick disassembly of the multiple circular protective covers 1.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
