Description

Technical Field

[0001] This utility model relates to the field of vehicle body structure technology, specifically to a screw cover plate for preventing loss. Background Technology

[0002] Currently, most screws on the vehicle body are installed on the B side of the product to avoid the screw heads being exposed after fixing the screws and affecting the appearance of the vehicle body. However, for some locations where screws must be fixed on the A side of the product, in order to avoid the screw heads being exposed, a screw cover plate is connected to the A side of the product. When the screw is fixed on the A side of the product, the screw cover plate is used to cover the screw head.

[0003] In existing technologies, screw cover plates are typically detachably attached to side A of the product. A mounting groove is usually created on side A; after the screw is secured, the screw cover plate is then attached to the groove. However, since the product and screw cover plate are manufactured simultaneously, and product assembly is completed at a different assembly station, pairing and delivery are necessary when transporting the product and screw cover plate or delivering them to the customer for self-assembly. During transportation and delivery, the screw cover plate is often unattached and easily lost, resulting in cost waste and impacting assembly schedules. Therefore, it is necessary to improve the existing screw cover plate structure to reduce the occurrence of lost screw cover plates. Utility Model Content

[0004] The present invention aims to provide a screw cover plate to prevent loss, thereby solving the problem that screw covers in the prior art are easily lost during transportation or product delivery.

[0005] To solve the above problems, the present invention adopts the following technical solution: a cover plate for preventing lost screws, including a cover plate body, a snap-fit ​​part provided at one end of the cover plate body, a connecting part connected to the end of the cover plate body opposite to the snap-fit ​​part, an elastic compression frame connected to the connecting part, the elastic compression frame being formed by four parallelogram-shaped frame edges connected end to end, and an anti-retraction part fixedly connected to the outer side of the elastic compression frame.

[0006] The principles and beneficial effects of this application are as follows: In this application, a snap-fit ​​part is connected to the cover plate body. It is only necessary to open a slot on the A side of the product in the prior art to snap the cover plate body and the snap-fit ​​part. When fixing, the cover plate body is snapped into the slot. The snap-fit ​​part and the slot engage with each other, which can prevent the cover plate body from loosening and falling off after being connected to the slot, so that the cover plate body can shield the screws connected in the slot.

[0007] In addition, this application includes a connecting part on the cover plate body, and an elastic compression frame is provided on the connecting part. Since the elastic compression frame is composed of four parallelogram-shaped sidewalls connected end to end, when an external force is applied to compress the elastic compression frame inward, the elastic compression frame will shrink. When installing the cover plate body, only a through hole communicating with the slot needs to be opened on the product. The connecting part and the elastic compression frame can pass through the through hole after being compressed and elastically contracted. When the compressive force on the elastic compression frame disappears, the elastic compression frame automatically resets, so that the anti-retraction part fixedly connected to the outside of the elastic compression frame forms a limiting engagement with the B side of the product, preventing the elastic compression frame and the anti-retraction part from exiting the through hole and falling off. At this time, under the connecting action of the connecting part, even if the entire cover plate body is separated from the slot, the cover plate body will not fall off the product due to the connecting action of the elastic compression frame and the anti-retraction part. After the screws are installed, the cover plate body can be snapped into the slot, which can cover the screws and improve the aesthetics.

[0008] Therefore, by adopting the technical solution in this application, not only can the cover plate body be easily snapped into the slot to cover the screws installed during assembly, but also, before assembly, the connection limit of the connecting part and the anti-retraction part can form a connection between the cover plate body and the product, avoiding the cover plate body from falling off and being lost before the screws are assembled. In addition, in this application, the connecting part is set on the end of the cover plate body directly opposite the snapping part, avoiding the connection part from affecting the snapping part and the slot structure opened on the product, thus improving the operability and stability of the connection between the cover plate body and the product.

[0009] Preferably, as an improvement, the elastic compression frame consists of two adjacent first borders and two adjacent second borders, with the connecting part fixedly connected to the connection position of the two first borders; the number of anti-retraction parts is two, and the two anti-retraction parts are fixedly connected to two points at the connection positions of the two first borders and the two second borders, respectively.

[0010] In this solution, the connecting part is connected to the connection position where the two first frames are connected to each other, so that the connecting part can evenly transmit the force to the elastic compression frame. In addition, the two anti-retraction parts are respectively set at two points at the connection positions of the two first frames and the two second frames and fixedly connected. When the entire elastic compression frame passes through the through hole of the product, the two anti-retraction parts can simultaneously play the role of blocking the elastic compression frame, so as to form a stable connection between the entire elastic compression frame and the product and prevent the cover plate body from being lost.

[0011] Preferably, as an improvement, the anti-reverse part includes an anti-reverse stop protrusion fixedly connected to the connection position between the first frame and the second frame, and the anti-reverse stop protrusion is arranged along the length direction of the second frame.

[0012] In this design, the anti-backlash protrusion is set along the length of the second frame, which not only allows the elastic compression frame to easily pass through the through hole on the product and be installed and limited, but also allows the anti-backlash protrusion to easily and stably abut against the product after the elastic compression frame is installed, thereby preventing backlash and improving the stability of the connection between the elastic compression frame and the product.

[0013] Preferably, as an improvement, the elastic compression frame is connected to a guide portion, which is fixedly connected to the two second frames at their respective connection points.

[0014] In this design, the guide is located at the connection point of the two second frame edges. When the elastic compression frame is inserted into the through hole of the product, the guide first contacts the through hole. At this time, the guide can guide the insertion of the elastic compression frame into the through hole, making it convenient for the elastic compression frame to be installed quickly and accurately.

[0015] Preferably, as an improvement, the guide portion includes a guide protrusion fixedly connected to the position where the two second frames are connected to each other, and the guide protrusion is arranged along the direction of the reverse extension of the angle bisector of the two second frames.

[0016] In this design, the guide protrusion is located on the reverse extension line of the angle bisector of the two second frame sides. When the elastic compression frame is installed into the through hole, the two second frame sides of the elastic compression frame are subjected to more uniform force, which is conducive to the stable and smooth installation of the elastic compression frame into the through hole.

[0017] Preferably, as an improvement, the guide portion and the anti-recoil portion are integrally formed with the elastic compression frame.

[0018] In this design, the guide section and anti-reverse section are integrally formed with the elastic compression frame, which is convenient to form and has a stable structure.

[0019] Preferably, as an improvement, the connecting part includes a connecting plate and a connecting strip that are fixedly connected to each other, with the connecting strip connecting between the connecting plate and the elastic compression frame.

[0020] In this solution, a connecting plate is set to ensure a stable connection between the connecting strip and the cover plate body. The connecting strip structure allows the elastic compression frame to form a flexible connection with the cover plate body through the connecting strip. After the elastic compression frame is installed, it can be stably connected to the through hole of the product, while the cover plate body can rotate and turn relative to the elastic compression frame, which facilitates the installation and connection of screws on the product.

[0021] Preferably, as an improvement, the snap-fit ​​part includes a snap-fit ​​spring plate and a snap-fit ​​protrusion fixedly connected to the snap-fit ​​spring plate. The snap-fit ​​protrusion is located on the side of the snap-fit ​​spring plate facing away from the cover plate body, and a guide slope is provided on the snap-fit ​​protrusion.

[0022] In this solution, when it is necessary to snap the cover plate body into the product's slot, simply insert one end of the cover plate body with the connecting part into the slot, and then press the cover plate body into the slot. Under the contact and pressing force between the guide slope of the snap protrusion and the product, the snap-fit ​​spring plate automatically deforms elastically, causing the snap protrusion to snap into the B side of the product. Thus, the cover plate body is snapped into the product's slot. The structure is simple and the installation is convenient.

[0023] Preferably, as an improvement, the snap-fit ​​spring plate is located in the plane of the outer side wall of the cover plate body on the side facing away from the cover plate body.

[0024] In this design, the side of the snap-fit ​​spring plate facing away from the cover plate body is located within the plane of the outer wall of the cover plate body. That is, the outer wall of the snap-fit ​​spring plate is recessed into the cover plate body, creating a gap between the outer wall of the snap-fit ​​spring plate and the outer wall of the cover plate body. When the cover plate body is installed in the product's slot, the gap between the outer wall of the snap-fit ​​spring plate and the side wall of the slot allows for easy manual insertion of auxiliary disassembly tools such as steel bars into the gap between the snap-fit ​​spring plate and the slot. Then, the snap-fit ​​spring plate is pried open to disengage the snap-fit ​​spring plate from the B-side of the product, facilitating the removal of the cover plate body for maintenance or screw replacement.

[0025] Preferably, as an improvement, the distance between the outer wall of the snap-fit ​​spring plate and the outer wall of the cover plate body is 1-2 mm.

[0026] In this solution, the distance between the outer wall of the snap-fit ​​spring plate and the outer wall of the cover plate body is set to 1-2mm. This not only allows for easy prying of the snap-fit ​​spring plate with tools to remove the cover plate body, but also avoids excessive gaps between the snap-fit ​​spring plate and the side wall of the slot due to excessive spacing, effectively ensuring the aesthetics of the cover plate body after it is installed on the A side of the product.

[0032] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: cover plate body 1, snap-fit ​​spring plate 2, snap-fit ​​protrusion 3, guide slope 301, connecting plate 4, connecting strip 5, first frame 6, second frame 7, anti-backward protrusion 8, door body 9, slot 901, through hole 902, and guide protrusion 10.

[0033] Example 1 This embodiment is as shown in the appendix. Figure 1 and Figure 2 As shown: A screw cover for preventing loss includes a cover body 1. One end of the cover body 1 is provided with a snap-fit ​​part, which includes a snap-fit ​​spring plate 2 and a snap-fit ​​protrusion 3 fixedly connected to the snap-fit ​​spring plate 2. The left side wall of the cover body 1 is provided with a groove. The snap-fit ​​spring plate 2 is integrally formed in the groove. The side of the snap-fit ​​spring plate 2 facing away from the cover body 1 is located in the plane of the left side wall of the cover body 1, and the distance between the outer wall of the snap-fit ​​spring plate 2 and the cover body 1 is 1-2 mm, preferably 1.5 mm or 2 mm. The snap-fit ​​protrusion 3 is integrally formed on the side of the snap-fit ​​spring plate 2 facing away from the cover body 1. The outer end of the snap-fit ​​protrusion 3 away from the cover body 1 is provided with a guide slope 301 so as to snap the snap-fit ​​part to other products in the prior art.

[0034] Combination Figure 1 and Figure 2A connecting part is connected to the right end of the cover plate body 1, which is directly opposite the snap-fit ​​spring plate 2. An elastic compression frame is connected to the connecting part, and an anti-retraction part is fixedly connected to the outer side of the elastic compression frame. The connecting part includes a connecting plate 4 and a connecting strip 5 fixedly connected to the connecting plate 4. The connecting strip 5 connects the connecting plate 4 and the elastic compression frame and has a certain degree of flexibility, allowing it to twist or bend. The connecting plate 4 and the connecting strip 5 are integrally injection molded to the cover plate body 1. In this embodiment, the elastic compression frame is formed by integrally injection molding four parallelogram-shaped frames connected end-to-end. The four frames include two adjacent first frames 6 and two adjacent second frames 7. In this embodiment, the first frames 6 and the second frames 7 are of equal length and have the same cross-sectional size and shape. In other embodiments besides this one, the first frames 6 and the second frames 7 may be different, which will not be elaborated here. The connecting strip 5 is integrally formed at the connection point between the end away from the connecting plate 4 and the two first frame 6. When the connecting strip 5 is not subjected to external force, it is located on the reverse extension line of the angle bisector of the two first frame 6. There are two anti-recoil parts, which are integrally formed at two points corresponding to the connection point of the first frame 6 and the second frame 7. The anti-recoil part includes an anti-recoil protrusion 8 provided along the length direction of the second frame 7. The cross-section of the anti-recoil protrusion 8 is the same as the cross-section shape and size of the second frame 7 so that the anti-recoil protrusion 8 can be injection molded on the second frame 7. The length of the anti-recoil protrusion 8 is 3-5mm, preferably 4mm or 5mm.

[0035] Combination Figure 3 and Figure 4 When the anti-loss screw cover plate of this embodiment is installed on the product, the product is described with the door body 9 as an example. The door body 9 is provided with a slot that cooperates with the cover plate body 1. The slot is recessed into the door body 9. The slot is provided with a slot 901 and a through hole 902 that penetrate the door body 9. The width of the through hole 902 is less than the distance between the two anti-backward protrusions 8. When installing the anti-loss screw cover, first manually press the two anti-retraction protrusions 8 inwards towards the elastic compression frame. The two anti-retraction protrusions 8 transmit the pressure to the elastic compression frame, causing the elastic compression frame to be compressed. This compression allows the anti-retraction protrusions 8 and the elastic compression frame to pass through the through hole 902. After passing through the through hole 902, the elastic compression frame automatically resets, causing the anti-retraction protrusions 8 to reset outwards. At this time, due to the blocking effect of the two anti-retraction protrusions 8, the anti-retraction protrusions 8 cannot automatically exit the through hole 902, causing the elastic compression frame and the anti-retraction protrusions 8 to automatically connect at the position of the through hole 902. With the connection of the connecting strip 5 and the connecting plate 4, the cover body 1 can be effectively prevented from being lost.

[0036] When the screws in the prior art are installed into the slot of the door body 9, the cover plate body 1 can be pressed to insert the snap-fit ​​spring plate 2 into the slot 901. After the guide slope 301 on the snap protrusion 3 contacts and abuts against the side wall of the slot, the snap-fit ​​spring plate 2 undergoes elastic deformation. When the snap protrusion 3 is inserted into the B side of the door body 9, it automatically snaps into the door body 9. At this time, the snap-fit ​​spring plate 2 automatically resets, so that the cover plate body 1 is snapped into the slot. The cover plate body 1 can shield the screw head connected in the slot.

[0037] Example 2 The difference between Example 2 and Example 1 is as follows: Figure 5 As shown, the elastic compression frame is connected to a guide portion, which includes a guide protrusion 10 connected to the junction of the two second side frames 7. The guide protrusion 10 is integrally formed with the two second side frames 7, and is arranged along the reverse extension of the angle bisector of the two second side frames 7. In this embodiment, by providing the guide protrusion 10, when the elastic compression frame is compressed and inserted into the through hole 902 of the door body 9, the guide protrusion 10 guides the insertion process, making the installation of the elastic compression frame more convenient, accurate, and efficient.
