[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Please refer to Figures 1 to 4 The utility model provides a screw protection member, which includes: a base 1, on which a plurality of positioning structures 12 are provided, and the plurality of positioning structures 12 are sequentially arranged along the circumference of the base 1, and at least part of the positioning structures 12 is protruded from the outer peripheral surface of the main part of the base 1; a top cover 2, which is detachably matched with the base 1, and when the top cover 2 is matched with the base 1, an accommodating cavity for accommodating the screw head of the screw 10 is formed between the base 1 and the top cover 2.

[0025] With the screw guard of this structural design, when in use, the base 1 and the top cover 2 cooperate to form a receiving cavity, which can wrap and protect the screw head of the screw 10, thereby reducing the risk of damage to the screw head caused by external factors. Since a plurality of raised positioning structures 12 are designed on the outer peripheral surface of the base 1, when the screw guard is in use, when the base 1 is placed in the screw mounting hole of the mounting base 20, the positioning structure 12 can contact the inner wall of the screw mounting hole, thereby positioning and fixing the base 1, ensuring that the screw 10 can be accurately and smoothly installed in the screw mounting hole, and will not cause adverse effects on the installation of the screw. The screw guard of the embodiment of the utility model solves the technical problem in the related art that the screws are easily damaged by the external environment after installation.

[0026] In addition, the screw guard can isolate the screw head from surrounding objects, and can prevent the screw head from scratching the surface of the device where it is located. After the screw guard wraps the screw head, it can also improve the aesthetics of the screw installation location.

[0027] The circumference of the base 1 needs to be determined with reference to the situation when it is used, and the circumference of the base 1 is consistent with the circumference of the screw 10 .

[0028] In a preferred embodiment, the protrusion height of the positioning structure 12 gradually increases along a preset direction, wherein the preset direction is a direction from the base 1 to the top cover 2 .

[0029] In this embodiment, the height of the protrusion of the positioning structure 12 is designed to be a gradually increasing structure along the direction from the base 1 to the top cover 2. In this way, when the base 1 is installed in the screw mounting hole, as the base 1 is pressed in, the pressure between the positioning structure 12 and the inner wall of the screw mounting hole will gradually increase, thereby making the base 1 more stably positioned in the screw mounting hole.

[0030] In an optional embodiment, the positioning structure 12 is a strip-shaped protrusion extending along a preset direction, so that the base 1 can be easily inserted into the screw installation hole and can play a good anti-twist effect when the screw 10 is screwed in, preventing the base 1 from rotating with the screw 10.

[0031] The base 1 is provided with a first snap-fitting portion 11 , and the top cover 2 is provided with a second snap-fitting portion 21 . When the base 1 is matched with the top cover 2 , the first snap-fitting portion 11 is snap-fitted with the second snap-fitting portion 21 .

[0032] In this embodiment, the base 1 and the top cover 2 are connected by the snap fit between the first snap fit portion 11 and the second snap fit portion 21. This structural design can make the fit between the base 1 and the top cover 2 faster, which is conducive to improving the installation speed of the screw guard. Of course, in actual implementation, there can be other ways for the fit between the base 1 and the top cover 2: for example, matching threads are designed on the base 1 and the top cover 2, and the two are connected and matched by threaded connection. For another example, the base 1 and / or the top cover 2 are made of deformable material. When the two are matched, a part of one is inserted into the other, so that a certain amount of interference is formed under the elastic action of the material to achieve the connection between the two.

[0033] The first snap-fitting portion 11 is a slot provided on the side wall of the base 1 , and the second snap-fitting portion 21 includes a main body structure and a protruding structure provided on the main body structure. When the first snap-fitting portion 11 is snap-fitted with the second snap-fitting portion 21 , the protruding structure is embedded in the slot.

[0034] In this embodiment, the main body structure is extended along a preset direction, and the protruding structure is arranged at the free end of the main body structure.

[0035] In this embodiment, a guide portion 13 is provided on the base 1, and the guide portion 13 has a guide surface. When the top cover 2 and the base 1 are close to each other, the second snap-fitting portion 21 contacts the guide surface, and under the guidance of the guide surface, the protruding structure moves into the groove.

[0036] By designing the guide portion 13, when the top cover 2 is buckled against the base 1, the guide surface of the guide portion 13 contacts the second snap-fitting portion 21, thereby guiding its movement trajectory, so that the protruding structure can smoothly move into the slot, thereby realizing the snap-fitting of the first snap-fitting portion 11 and the second snap-fitting portion 21. The design of the guide portion 13 can effectively facilitate the matching between the first snap-fitting portion 11 and the second snap-fitting portion 21, so that the screw guard can be assembled without strictly aligning the first snap-fitting portion 11 and the second snap-fitting portion 21 during use, which is conducive to improving the assembly efficiency of the screw guard.

[0037] Optionally, there are multiple first snap-fitting parts 11 and multiple second snap-fitting parts 21, and the multiple first snap-fitting parts 11 are arranged in a one-to-one correspondence with the multiple second snap-fitting parts 21; and / or, there are multiple guide parts 13 and multiple second snap-fitting parts 21, and the multiple guide parts 13 are arranged in a one-to-one correspondence with the multiple second snap-fitting parts 21.

[0038] In a preferred embodiment, a first notch 22 is provided at an edge of a side of the top cover 2 close to the base 1 , and / or a second notch is provided at an edge of a side of the base 1 close to the top cover 2 .

[0039] By designing a first notch 22 on the edge of one side of the top cover 2 close to the base 1 and / or designing a second notch on the edge of one side of the base 1 close to the top cover 2, an effective force point can be provided, so that it is convenient to apply force to separate the top cover 2 from the base 1. For example, in actual implementation, the top cover 2 can be removed from the base 1 by inserting a screwdriver or a fingernail into the first notch 22 or the second notch. In a preferred embodiment, the first notch 22 is an annular notch, and the annular notch is extended along the circumference of the top cover 2 of the base 1.

[0040] In this embodiment, a screw avoidance hole 14 is provided on the base 1, and the screw avoidance hole 14 connects the accommodating cavity and the external space of the screw protection member.

[0041] In this embodiment, the base 1 is provided with a screw avoidance hole 14 for the screw to pass through. Of course, in some embodiments, the screw avoidance hole 14 may not be provided, and the screw may drill a matching avoidance hole on the base 1 under its own action when being installed.

[0042] In addition, the utility model further provides a screw assembly, which includes a screw 10 and the above-mentioned screw protective member, and the screw head of the screw 10 is wrapped and arranged in the accommodating cavity of the screw protective member.

[0043] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0044] The screw protection member of the utility model comprises: a base 1, on which a plurality of positioning structures 12 are arranged in sequence along the circumference of the base 1, and at least part of the positioning structures 12 is protruded from the outer peripheral surface of the main part of the base 1; a top cover 2, which is detachably matched with the base 1, and when the top cover 2 is matched with the base 1, a receiving cavity for accommodating the screw head of the screw 10 is formed between the base 1 and the top cover 2. When the screw protection member adopts this structural design, when in use, the base 1 and the top cover 2 cooperate to form a receiving cavity, which can wrap and protect the screw head of the screw 10, thereby reducing the risk of damage to the screw head caused by external factors. Since a plurality of protruding positioning structures 12 are designed on the outer peripheral surface of the base 1, when the screw protection member is in use, when the base 1 is placed in the screw mounting hole of the mounting base 20, the positioning structure 12 can contact the inner wall of the screw mounting hole, thereby positioning and fixing the base 1, ensuring that the screw 10 can be accurately and smoothly installed in the screw mounting hole, and will not cause adverse effects on the installation of the screw. The screw protection member of the embodiment of the utility model solves the technical problem in the related art that the screws are easily damaged by the external environment after installation.
