Description

Technical Field

[0001] This utility model relates to the field of rubber protective sleeve technology, and in particular to an easy-to-install automotive rubber protective sleeve. Background Technology

[0002] The rubber protective sleeve (CV joint sleeve) of an automotive driveshaft is a key component protecting the universal joint. It ensures smooth power transmission and extends the driveshaft's life by sealing the internal lubricant and isolating it from external dust and moisture. This component is a wear part and requires periodic replacement. Therefore, it must be easy to install: a simple installation design significantly reduces maintenance time and labor costs, avoids improper installation or incomplete sealing due to complex operations, thus ensuring protective effectiveness and encouraging vehicle owners to replace it promptly to prevent minor issues from causing major problems.

[0003] When replacing and installing traditional automotive driveshaft rubber protective sleeves, workers usually need to use tools to enlarge the small opening of the protective sleeve, then use tools to put the rubber protective sleeve onto the surface of the driveshaft, align its large opening with the groove of the housing, and then use special tools to tighten the new metal clamp. This results in workers having to perform a lot of intensive disassembly work to replace a small part, which is extremely time-consuming and labor-intensive, leading to high maintenance costs. Furthermore, the need to use large tools to operate the rubber protective cover in a confined space causes great inconvenience to the workers. Utility Model Content

[0004] Therefore, it is necessary to provide a car rubber protective cover that is easy to install, addressing the problem that traditional car rubber protective covers are inconvenient to replace.

[0005] An easy-to-install car rubber protective cover includes: two rubber shells cut in half from the middle.

[0006] Multiple quick-release mechanisms are mounted on the surface of the rubber housing. Each quick-release mechanism includes multiple reinforcing members that are fixedly connected to the surface of the rubber housing. Each reinforcing member is arranged in a semi-circular shape, and each of the reinforcing members on the surface of the rubber housing has a fixing claw at both ends.

[0007] In one embodiment, two fixing claws located on the same reinforcing member are used in cooperation. One of the fixing claws has a card block fixedly connected to its end away from the reinforcing member, and the other fixing claw located on the same reinforcing member has a card slot corresponding to the card block at its end away from the reinforcing member.

[0008] In one embodiment, a top block is slidably connected to the inner wall of the card block. The cross-section of the top block is a right-angled triangle with an arc. Multiple springs are fixedly connected between the bottom end of the top block and the inner bottom wall of the card block.

[0009] In one embodiment, a buffer pad is fixedly connected to the inner side of the fixing claw, and connectors are fixedly connected to both ends of the outer side of the reinforcement part on which the fixing claw is provided, and the fixing claw is hinged to the connectors.

[0010] In one embodiment, the reinforcement with the fixing claw has insertion holes at both ends, and the reinforcement without the fixing claw has insertion blocks fixedly connected to both ends corresponding to the insertion holes.

[0011] In one embodiment, multiple resistance blocks are fixedly connected to both the upper and lower ends of the insertion block, and the resistance blocks are arranged in a hemispherical shape.

[0012] In one embodiment, a plurality of filler strips are fixedly connected to the cross-sectional side of the rubber housing on which the insert is provided, the filler strips being arranged along the cross-sectional wall of the rubber housing.

[0013] In one embodiment, the cross-sectional side of the rubber shell with the fixing claw is provided with a plurality of sealing grooves corresponding to the filler strip.

[0014] Beneficial effects 1. By splitting the rubber protective shell into two outer rubber shells in the middle and setting a reinforcement and fixing claw between the two outer rubber shells for quick installation, the extensive disassembly of the drive shaft assembly required for replacing the protective shell is avoided, significantly reducing labor intensity and time costs. During installation, there is no need to use tools to forcibly pry open the small port, eliminating the risk of damage to the rubber parts during operation, and overcoming the inconvenience of using large tools in confined spaces. The cooperation between the reinforcement and fixing claw ensures the reliability of the shell docking, realizes rapid on-site assembly, greatly improves maintenance efficiency and reduces overall maintenance costs. 2. By setting multiple inserts and holes at the connection between the two rubber shells for precise matching, the split shell can be quickly pre-positioned and radially limited, effectively restricting misalignment and offset during installation. At the same time, the tight engagement of the filler strip and the sealing groove forms multiple redundant sealing barriers, which significantly improves the airtightness of the connection interface and reduces the probability of dust and moisture intrusion and grease leakage. Thus, while ensuring convenient and efficient installation, it also ensures the long-term stable operation and service life of the drive shaft universal joint. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figure 1 - Figure 5 This invention describes an easy-to-install automotive rubber protective cover.

[0020] In one embodiment, an easy-to-install automotive rubber protective cover includes: two rubber shells 100 cut in half from the middle; Multiple quick-installation mechanisms 200 are installed on the surface of the rubber housing 100. Each quick-installation mechanism 200 includes multiple reinforcing members 210 fixedly connected to the surface of the rubber housing 100. Each reinforcing member 210 is arranged in a semi-circular shape. Both ends of one of the reinforcing members 210 on the surface of the rubber housing 100 are provided with fixing claws 220.

[0021] In this device, the reinforcing member 210 is made of stainless steel, and the two rubber shells 100 of this device, when combined, form a standard ball cage sleeve. The reinforcing member 210 is located at the multi-section connection of the ball cage sleeve, which improves the overall durability of the rubber shell 100 and provides a rigid connection point for the fixing claw 220. The materials in this device are all common hardware parts on the market, and the materials can be selected according to the actual needs of the user to control the processing cost. All the components in this device are for single use. When disassembling this device, it can be directly removed from the drive shaft by breaking it with a tool.

[0022] like Figure 2 , Figure 4 and Figure 5 As shown, two fixing claws 220 located on the same reinforcing member 210 cooperate in use. One fixing claw 220 has a locking block 221 fixedly connected to its end away from the reinforcing member 210, and the other fixing claw 220 located on the same reinforcing member 210 has a locking groove 223 corresponding to the locking block 221 at its end away from the reinforcing member 210. A top block 2211 is slidably connected to the inner wall of the locking block 221. The cross-section of the top block 2211 is a right-angled triangle with an arc. Multiple springs 2212 are fixedly connected between the bottom end of the top block 2211 and the inner bottom wall of the locking block 221. A buffer pad 241 is fixedly connected to the inner side of the fixing claw 220. Both ends of the outer side of the reinforcing member 210 with the fixing claw 220 are fixedly connected to the connecting member 240, and the fixing claw 220 is hinged to the connecting member 240.

[0023] In this embodiment, the fixing claws 220 at the multi-section connection of the rubber shell 100 are all adapted to the size of the connection. The connector 240 consists of two fixing blocks and a rotating shaft. The end of the fixing claw 220 near the reinforcing member 210 is rotatably connected to the rotating shaft and forms a hinge under the constraint of the reinforcing member 210. The thickness of the buffer pad 241 is greater than the surface of the drive shaft to the reinforcing member 210. Therefore, after each set of fixing claws 220 are interlocked, the buffer pad 241 is in a compressed state. The buffer pad 241 is used to fill the gap between the fixing claw 220 and the reinforcing member 210, while reducing the force between the fixing claw 220 and the fixing member, so as to improve the durability of the fixing claw 220 and the reinforcing member 210. It should be noted that this device cuts a traditional one-piece rubber protective sleeve in the middle into two rubber shells 100, and sets a quick-installation mechanism 200 between the two rubber shells 100 to fix them, so that the two rubber shells 100 can be installed quickly to achieve an optimized effect. This device is only used to isolate and protect the components in the drive shaft, so the quick-installation mechanism 200 can achieve the effect of stably connecting the two rubber shells 100 and provide a certain connection support force at the connection between the two rubber shells 100, without causing any impact on the internal structure or normal use of the rubber shells 100.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the reinforcing member 210 with fixing claws 220 has insertion holes 212 at both ends, and the reinforcing member 210 without fixing claws 220 has insertion blocks 211 fixedly connected to both ends corresponding to the insertion holes 212. Multiple resistance blocks 2111 are fixedly connected to both the upper and lower ends of the insertion blocks 211, and the resistance blocks 2111 are hemispherical. Multiple filler strips 230 are fixedly connected to the cross-sectional side of the rubber shell 100 with insertion blocks 211, and the filler strips 230 are arranged along the cross-sectional wall of the rubber shell 100. Multiple sealing grooves 231 corresponding to the filler strips 230 are opened on the cross-sectional side of the rubber shell 100 with fixing claws 220.

[0025] In this embodiment, when installing the device, since the drive shaft is located at the bottom of the car and surrounded by a large number of car components, it is impossible for the operator to directly align each set of fixing claws 220. Therefore, when the operator installs the rubber shell 100, it is necessary to use multiple sets of insertion holes 212 in conjunction with insertion blocks 211 for pre-positioning. After the insertion block 211 is inserted into the insertion hole 212, the resistance block 2111 on the insertion block 211, in conjunction with the corresponding groove in the insertion hole 212, achieves a certain resistance effect, fixing the two rubber shells 100 into a complete rubber protective sleeve. Then, the rubber protective shell is precisely reinforced by multiple sets of fixing claws 220 to improve its durability.

[0026] Working principle: When installing the rubber housing 100, the operator needs to place two corresponding rubber housings 100 on the corresponding positions of the drive shaft and align the insertion hole 212 with the insertion block 211. At this time, the two rubber housings 100 are combined into a rubber protective sleeve. Then, the operator inserts the two fixing claws 220 together. During this process, the locking block 221 of one of the fixing claws 220 will be inserted into the slot 223. During the insertion process, the inclined surface of the top block 2211 is squeezed into the inside of the locking block 221 by the surface of the other fixing claw 220 and compresses the spring 2212 until the top block 2211 is completely inserted into the inside of the locking block 221. At this time, the locking block 221 moves into the depth of the slot 223 until the front end of the locking block 221 abuts against the end of the slot 223. At this time, the top block 2211 enters the preset position in the slot 223 and the locking is completed. Repeat the above operation to lock multiple sets of fixing claws 220 together and fix the rubber protective shell on the surface of the drive shaft.

[0027] It should be noted that the rubber housing 100, spring 2212, buffer pad 241 and filler strip 230 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
