BRIEF DESCRIPTION OF DRAWINGS

[0026] Figure 1 The overall structure of an embodiment of the present application is shown in the figure.

[0027] In the drawings, the components represented by the numbers are listed as follows:

[0028] 1, protective device body; 2, protective device fixing marker; 3, water absorbing part; 4, sealing guide part; 5, sealing ball; 6, cover plate; 7, speed difference device. DETAILED DESCRIPTION

[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0030] Firstly, such as Figure 1 As shown, this utility model provides a protective device for a differential speed device, including: a protective device body 1. Since the inlet and outlet of the wire rope on the differential speed device housing is the only "open" point, during installation, the protective device body 1 is directly installed at the inlet and outlet of the wire rope of the differential speed device 7. The wire rope passes through the protective device body 1, thus protecting the differential speed device 7. Furthermore, a water-absorbing component 3 and a sealing guide component 4 are sequentially arranged inside the protective device body 1 in the direction away from the differential speed device 7. It is conceivable that a first opening is provided inside the protective device body 1 for the wire rope to pass through, and the wire rope also passes through the water-absorbing component 3 and the sealing guide component 4, i.e., the water-absorbing component 3 and the sealing guide component 4 cover the outer wall of the first opening. During the stretching and retraction of the wire rope, the water-absorbing component 3 removes moisture, salt, dust, and other foreign matter adhering to the wire rope, thereby protecting the differential speed device 7.

[0031] In this embodiment, by directly installing the protective device body 1 at the wire rope inlet and outlet of the differential speed device 7 and wrapping the wire rope, a physical barrier is formed. The water-absorbing component 3 installed inside the protective device body 1 can efficiently remove moisture, salt, dust, and other foreign matter adhering to the wire rope, effectively preventing external impurities and moisture from directly intruding into the differential speed device 7, thereby extending the service life of the differential speed device 7, improving its performance stability, and reducing maintenance costs. The sealing guide component 4 not only further enhances the sealing performance of the protective device and prevents interference from the external environment, but also guides the wire rope. During the stretching and retraction of the wire rope, the sealing guide component 4 ensures that the wire rope maintains the correct path, avoiding unnecessary friction and wear, and further protecting the water-absorbing component 3.

[0032] like Figure 1 As shown, in the preferred embodiment, a cover plate 6 is further provided between the protective device body 1 and the differential gear 7. The size of the cover plate 6 is approximately the same as the size of the end of the protective device body 1 near the differential gear 7, so that both the protective device body 1 and the cover plate 6 are fixed to the housing of the differential gear 7 by the protective device fixing bracket 2. In this embodiment, the protective device fixing bracket 2 can be a threaded fastener. By using the protective device fixing bracket 2 to install the cover plate 6 and the protective device body 1, the installation process is simpler and faster, which not only improves the installation efficiency but also facilitates subsequent maintenance and replacement work.

[0033] It is conceivable that a second opening is provided on the cover plate 6 for the steel wire to pass through, and the first opening is coaxial with the second opening. The coaxial first opening and the second opening provide a continuous and unobstructed passage for the steel wire, ensuring smooth operation of the steel wire during stretching and retraction. In this embodiment, the axis of the first opening and the second opening is on the central axis of the protective device body 1.

[0034] As Figure 1 shown, in a preferred embodiment, the protective device body 1 is provided with a protrusion on the side close to the cover plate 6. Specifically, the protrusion extends radially away from the protective device body 1, and a connecting hole is provided on the protrusion for cooperation with the protective device fixing member 2. Similarly, the cover plate 6 is also provided with a mounting hole for cooperation with the protective device fixing member 2. During installation, the protective device fixing member 2 passes through the connecting hole and the mounting hole to fix the protective device body 1 and the cover plate 6 to the housing of the speed differential device 7. The protrusion provides installation space for the protective device fixing member 2, achieving firm fixation of the protective device body 1, the cover plate 6 and the housing of the speed differential device 7, and ensuring the stability and safety of the overall structure.

[0035] As Figure 1 shown, one end of the water absorption member 3 abuts against the cover plate 6, and the other end of the water absorption member 3 abuts against one end of the sealing guide member 4. In this embodiment, the cover plate 6 is used for limiting the water absorption member 3 to prevent it from falling into the speed differential device 7 when it loosens, and the other end of the water absorption member 3 is limited by the sealing guide member 4 to ensure its continuous and normal operation. The water absorption member 3 can be made of a relatively soft material with water absorption and scraping effect, such as sponge, sodium polyacrylate, etc.

[0036] As Figure 1 shown, the other end of the sealing guide member 4 away from the water absorption member 3 extends to the end of the protective device body 1 away from the speed differential device 7. During installation, the sealing guide member 4 is interference-fitted with the inner wall of the cavity of the protective device body 1 to fix its position, greatly simplifying the installation process. The sealing guide member 4 can be made of a relatively hard material, such as PVC or other hard plastic.

[0037] As Figure 1As shown, after the protective device is installed on the housing of the speed differential device 7, the end of the sealing guide part 4 away from the water absorbing part 3 is directly in contact with the sealing ball 5 at the end of the steel wire rope. In order to avoid the "open mouth", prevent the water vapor, salt mist and dust in the atmosphere from entering the speed differential device 7 during the stretching and retraction of the steel wire rope, the end of the sealing guide part 4 in contact with the sealing ball 5 is designed as a circular arc concave to the inside of the protective device body 1, which is consistent with the shape of the outer wall of the sealing ball 5, so that the sealing ball 5 is pulled away from the sealing guide part 4 when the steel wire rope is pulled down, and the sealing ball 5 contacts the sealing guide part 4 when the steel wire rope is retracted, thereby achieving sealing.

[0038] In the present embodiment, the sealing guide part 4 also has a sealing function, which is used to close the steel wire rope port by the spherical shape when the speed differential device 7 is not in use, that is, when the steel wire rope is fully retracted. The end of the sealing guide part 4 in contact with the sealing ball 5 is designed as a circular arc concave to the inside of the protective device body 1, which is consistent with the shape of the outer wall of the sealing ball 5, thereby ensuring that the sealing ball 5 is tightly attached to the sealing guide part 4 during the pulling down and retraction of the steel wire rope, and effectively preventing the water vapor, salt mist and dust from entering the speed differential device 7, thereby protecting the speed differential device 7.

[0039] In some preferred embodiments, a cover plate 6 is further arranged between the protective device and the housing of the speed differential device 7.

[0040] In the above scheme, the protective device is directly installed at the outlet of the steel wire rope, which can reduce the erosion of the external environment, such as dust, moisture, corrosive substances, etc. to the inside of the speed differential device 7, thereby prolonging the overall service life of the speed differential device 7. Due to the protection of the protective device, the maintenance frequency and cost of the speed differential device 7 can be significantly reduced, and the protective device is directly installed on the housing of the speed differential device 7, without the need for additional mounting brackets or fixing devices, thereby simplifying the installation process.

[0041] Although the embodiments of the utility model have been shown and described above, it should be understood that the above embodiments are exemplary and cannot be understood as limiting the utility model. Those skilled in the art can make changes, modifications, replacements and modifications to the above embodiments within the scope of the utility model.
