[0025] The specific embodiments of the present invention are described in detail below. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the orientation in the assembled use state. "Inside" and "outside" refer to the inside and outside relative to the contour of each component itself.
[0026] The present invention provides a fastener protection device, such as Figure 1 or Figure 2 As shown, the fastener protection device includes an elastic protection body, which includes an upper protective cover 10 and a lower protective cover 20 that are connected to each other and have openings facing each other, and the upper protective cover 10 and the lower protective cover 20 have a tendency to approach each other to close the openings; the upper protective cover 10 and the lower protective cover 20 include a cavity for covering the fastener and a wall portion that defines the cavity; the fastener protection device also includes a fastening structure 30 for tightening the upper protective cover 10 and the lower protective cover 20 to facilitate fixing the upper protective cover 10 and the lower protective cover 20 on the fastener.
[0027] Through the above technical solution, after the nut 71 and the bolt 70 are fixed, the fastener protection device of the present invention can bypass the obstacles between the nut 71 and the bolt 70, and at the same time, the exposed nut 71 and the bolt 70 are placed in the fastener protection device to isolate the fastener from the external environment. In this way, not only can the fastener be protected, but also the fastener can be effectively prevented from rusting, corrosion and other problems.
[0028] It should be noted that the "bolt 70" mentioned above includes both the bolt head 73 and the screw shaft portion 72 of the bolt (see Figure 4 ).
[0029] Furthermore, the protective body can be made of rubber material.
[0030] In the above, the fastening structure 30 can be independently arranged or attached to the protective body.
[0031] Specific implementation method 1, as Figure 2 As shown, the fastening structure 30 is independently provided from the protective body. Specifically, the fastening structure 30 includes an elastic rubber ring independently provided from the protective body. Optionally, the rubber ring is provided as a rubber ring. Figure 3 As shown, the rubber ring can be put on the root of the upper protective cover 10 and / or the lower protective cover 20 to fix the upper protective cover 10 and / or the lower protective cover 20 on the fastener to prevent the upper protective cover 10 and the lower protective cover 20 from being separated from the fastener and losing the protective function.
[0032] It should be noted that the "root" refers to the position close to the opening of the upper protective cover 10 and the lower protective cover 20 after they are installed on the fastener; or, it refers to the position close to the obstacle 74 after the upper protective cover 10 and the lower protective cover 20 are installed on the fastener.
[0033] Specific implementation method 2: Figure 1 As shown, the fastening structure 30 is attached to the protective body. Specifically, the fastening structure 30 includes an elastic band attached to the protective body, and both ends of the elastic band are simultaneously connected to the wall of the upper protective cover 10 or the lower protective cover 20. Preferably, both ends of the elastic band are simultaneously connected to the wall of the lower protective cover 20; the elastic band is configured as a rubber band. The elastic band can be wound around the other protective cover starting from one of the protective covers to cover it firmly on the fastener. In this specific embodiment, after the upper protective cover 10 and the lower protective cover 20 are covered on the fastener, the elastic band is wound around the obstacle 74 starting from the lower protective cover 20 and wrapped around the upper protective cover 10, so that the upper protective cover 10 and the lower protective cover 20 can be firmly covered on the fastener.
[0034] In order to prevent the elastic band wound on the upper protective cover 10 from being separated from the upper protective cover 10, a groove may be provided on the circumferential side wall of the upper protective cover 10. When in use, the elastic band is inserted into the groove to prevent the elastic band from being separated from the upper protective cover 10.
[0035] Compared with the first embodiment, the second embodiment has the advantage that the fastening structure 30 and the fastening body are integrated into one body, thereby improving the portability of the fastener protection device.
[0036] Specific implementation method three: Specific implementation method one and specific implementation method two are combined, that is, the fastening structure 30 includes both the rubber ring in the specific implementation method one and the elastic band in the specific implementation method two.
[0037] In practice, generally speaking, Figure 4As shown, the height of the screw portion 72 protruding from the plane will be greater than the height of the bolt head 73 protruding from the plane. Therefore, in a preferred case, the lengths of the upper protective cover 10 and the lower protective cover 20 should be different. In an optional specific embodiment, the length of the upper protective cover 10 is greater than the length of the lower protective cover 20, and the elastic band is arranged on the lower protective cover 20. The opening edge of the upper protective cover 10 and the opening edge of the lower protective cover 20 are partially bonded together, and a gap 40 is provided between the remaining parts. It can also be understood that an opening is provided on the integrally formed upper protective cover 10 and lower protective cover 20, and the opening is the gap 40. The shape of the gap 40 can be various. However, it should be noted that the general direction of the gap 40 is arranged to extend along the circumference of the protective body, rather than extending axially.
[0038] It should be explained that the length of the upper protective cover 10 and the length of the lower protective cover 20 are measured as follows: the length of the upper protective cover 10 refers to the distance from the top of the upper protective cover 10 to the connection between the upper protective cover 10 and the lower protective cover 20; the length of the lower protective cover 20 is the distance from the bottom of the lower protective cover 20 to the connection between the upper protective cover 10 and the lower protective cover 20.
[0039] In an optional specific embodiment, the overall shape of the gap 40 is set to be an arc, so that a closing blade 50 can be formed at the opening of the upper protective cover 10 or the lower protective cover 20. Preferably, the closing blade 50 is formed at the opening of the lower protective cover 20. The function of the closing blade 50 is that when the lower protective cover 20 is covered on the fastener, the closing blade 50 helps the lower protective cover 20 to be tightly attached to the fastener.
[0040] The wall portion is provided with an oil filling hole 60, so that in subsequent maintenance, an anti-corrosion medium, such as butter or liquid oil, can be added to the protective body at any time through the oil filling hole 60 on the fastener protection device, so as to achieve lubrication and rust prevention of nuts and bolts at any time. Optionally, an oil filling hole 60 is provided at the top of the upper protection cover 10 and the bottom of the lower protection cover 20. Further, a sealing cover is provided at the oil filling hole 60, and the sealing cover can be a rubber plug.
[0041] To facilitate understanding of the technical solution of the present invention, the working principle of the present invention is briefly described below: When in use, Figure 3 or Figure 4As shown, the upper protective cover 10 is covered on the nut 71 and the screw part 72. Since the protective body is made of elastic rubber material, after the lower protective cover 20 is stretched, the lower protective cover 20 can be covered on the bolt head 73, and then the upper protective cover 10 and the lower protective cover 20 are fixed by the fastening structure 30 to prevent them from being separated from the nut 71 and the bolt 70. In the first embodiment, as shown in FIG. Figure 2-Figure 4 As shown, since the fastening structure 30 is independently arranged from the protective body, the fastening method is achieved by putting a rubber ring on the root of the upper protective cover 10 and / or the lower protective cover 20. Since the rubber ring has an inward contraction force, the upper protective cover 10 and / or the lower protective cover 20 can be tightly bound to the nut 71 and the bolt. Figure 1 Since the fastening structure 30 is attached to the protective body and the rubber belt is arranged on the wall of the lower protective cover 20, when fixing, the rubber belt needs to be stretched from the lower protective cover 20 to the upper protective cover 10 and wrapped around the upper protective cover 10. Preferably, the rubber belt is wrapped around the root of the upper protective cover 10. Although the fastening structure 30 of the second embodiment is not shown in the drawings, according to the above description and the first embodiment and Figure 3 Those skilled in the art can understand this implementation mode.
[0042] It should be noted that, in addition to the fastening structure 30 having a fastening effect on the fastener, the properties of the upper protective cover 10 and the lower protective cover 20 themselves also have a fastening effect. Specifically, since the upper protective cover 10 and the lower protective cover 20 are made of elastic rubber material, they themselves have an inward tightening force. In addition, after the installation, a certain friction force will be generated between the upper protective cover 10 and the lower protective cover 20 and the nut 71 and the bolt 70. These factors all help the upper protective cover 10 and the lower protective cover 20 to cover the fastener firmly.
[0043] It should be noted that the fastener protection device of the present invention is mainly aimed at Figure 4 The bolt 70 and nut 71 shown, and there is an obstacle between the bolt 70 and the nut 71. Of course, if the fastener protection device can be adapted to other fasteners, it is also applicable.
[0044] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.
[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
[0046] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
