Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic protective covers, and more particularly to a BDU plastic protective cover. Background Technology
[0002] refer to Figures 1-4 The existing plastic protective cover includes a mating cover body 1, an assembly cover body 2, and an installation structure disposed between the mating cover body 1 and the assembly cover body 2 for assembling the two. The installation structure includes a horizontal limiting component that limits the horizontal direction of the assembly cover body 2 when it is installed onto the mating cover body 1, and a vertical limiting component that limits the vertical direction of the assembly cover body 2. The horizontal limiting component includes a hook 3 protruding from one side wall of the mating cover body 1 and a locking plate 4 disposed on the assembly cover body 2 that engages with the hook 3 when the assembly cover body 2 is installed onto the mating cover body 1. The vertical limiting component… The component includes an elastic plate 5 at one end of the assembly cover 2 where a retaining plate 4 is provided. A limiting block 6 protrudes from the end of the elastic plate 5 away from the assembly cover 2. The mating cover 1 is provided with a limiting groove 7 for the limiting block 6 to be inserted when the assembly cover 2 is installed on the mating cover 1, and the top of the limiting block 6 abuts against the top surface of the limiting block 6. After the limiting block 6 is inserted into the limiting groove 7, the side of the limiting block 6 away from the elastic plate 5 abuts against the side wall of the limiting groove 7 and pushes the assembly cover 2 backward, so that the retaining plate 4 squeezes the hook 3, improving the tightness of the fit between the two, and reducing the probability of noise caused by the collision between the assembly cover 2 and the mating cover 1 when the plastic protective cover is in use.
[0003] The hooks on the mating cover in the above structure can engage with the locking plate on the mating cover when the assembly cover is installed into the mating cover, thereby limiting the horizontal direction of the assembly cover. However, after the limiting block is inserted into the limiting groove, the assembly cover will move away from the mating cover due to the push of the limiting block, causing the locking plate surface to press against the hooks, improving the tightness of the fit between the two. However, after being pressed for a long time, the hooks are prone to deformation, which reduces the horizontal limiting effect between the assembly cover and the mating cover, and the plastic protective cover is prone to making abnormal noises during use. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies, such as the tendency of the hook to deform under prolonged pressure, which reduces the horizontal limiting effect between the assembled cover and the mating cover, and causes abnormal noises during use. It provides a BDU plastic protective cover that reduces the probability of abnormal noises during use.
[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:
[0006] A BDU plastic protective cover includes a mating cover body, an assembly cover body, and an assembly structure for assembling the two. The assembly structure includes a horizontal limiting component that limits the horizontal direction of the assembly cover body after it is installed onto the mating cover body, and a vertical limiting component that limits the vertical direction of the assembly cover body after it is installed onto the mating cover body. The horizontal limiting component includes an installation groove recessed on one side of the mating cover body for the assembly cover body to be inserted into, limiting slots respectively provided on the side walls of the installation groove, and limiting plates respectively provided on both sides of the assembly cover body, which are inserted into the limiting slots to limit the horizontal direction of the assembly cover body when it is installed into the installation groove.
[0007] With the above solution, the limiting plates on both sides of the assembly cover can be inserted into the limiting slots on both sides of the mating cover mounting groove when the assembly cover is installed onto the mating cover, thereby achieving horizontal limiting between the assembly cover and the mating cover, reducing the probability of abnormal noise during use of the plastic protective cover. At the same time, since the horizontal limiting between the assembly cover and the mating cover is achieved through the insertion between the limiting plate and the limiting slot, and the limiting plate and the limiting slot have a low probability of deformation after long-term use, the service life of the plastic protective cover is improved.
[0008] Preferably, at least one pair of limiting plates are provided on both sides of the assembly cover, and the number and position of the limiting slots provided on the side walls of the mounting groove correspond one-to-one with the number and position of the limiting plates.
[0009] Preferably, the vertical limiting component includes a spring clip provided on one side wall of the assembly cover, a snap-fit block protruding on the side of the spring clip away from the assembly cover, and a snap-fit groove provided in the mounting groove for inserting the snap-fit block and for the top of the snap-fit block to abut against the top surface of the snap-fit block. A deformation limiting component is provided on the assembly cover to reduce the probability that the snap-fit block will fall out of the snap-fit groove due to the deformation of the spring clip.
[0010] Using the above solution, the snap-fit block on the spring clip can be inserted into the snap-fit groove in the mounting groove when the assembly cover is installed into the mounting groove on the mating cover, thereby achieving vertical positioning between the assembly cover and the mating cover. The deformation limiting component on the assembly cover can reduce the probability of deformation of the spring clip, thereby reducing the probability of the snap-fit block on the spring clip coming out of the snap-fit groove. At the same time, when one side of the abutment plate abuts against the spring clip, the spring clip will also apply a reaction force to the abutment plate, thereby pushing the assembly cover to move away from the mounting groove. At this time, one side of the limiting plate on both sides of the assembly cover will abut against the side wall of the limiting slot, thereby further reducing the probability of abnormal noise when the plastic protective cover is used.
[0011] Preferably, the deformation limiting component includes a groove provided on the top surface of the assembly cover, an abutment plate which, after being flipped over, abuts against the spring clip and limits the deformation of the spring clip, and a first limiting component that limits the position of the abutment plate when one end of the abutment plate is flipped over to abut against the spring clip, and a second limiting component that limits the position of the abutment plate when the end of the abutment plate abutting against the spring clip is flipped away from the spring clip.
[0012] Using the above solution, the abutment plate set in the groove can abut against the spring clip after being flipped over. The first limiting component then limits the flipped abutment plate, thereby reducing the probability of deformation of the spring clip when it is used under the plastic protective cover. This makes the engagement between the locking block and the locking groove on the spring clip more stable. The second limiting component can limit the position of the abutment plate when it is flipped away from the spring clip on the side that abuts against it, so that the abutment plate is stored in the groove, thereby reducing the probability of accidental damage to the abutment plate when it is not abutting against the spring clip.
[0013] Preferably, the first limiting component includes a first semi-circular hole provided on one side wall of the abutment plate, a second semi-circular hole provided on one side wall of the groove, which, when the abutment plate is flipped to one end to abut against the spring clip, combines with the first semi-circular hole to form an integral limiting hole, and a first limiting pin inserted into both the first semi-circular hole and the second semi-circular hole when one end of the abutment plate abuts against the spring clip.
[0014] Using the above solution, when the abutment plate is flipped to abut one end against the spring clip, the first semicircular hole on the abutment plate and the second semicircular hole on the side wall of the groove will fit together to form a whole limiting hole. Then, inserting the first limiting pin into the limiting hole formed by the first semicircular hole and the second semicircular hole can restrict the abutment plate from flipping, so that the abutment plate remains in abutting one end against the spring clip.
[0015] Preferably, the second limiting component includes a through hole vertically disposed on the abutment plate, an insertion hole disposed on the bottom surface of the groove that is opposite to the through hole when the end of the abutment plate that abuts against the spring is flipped away from the spring, and a second limiting pin that passes through the through hole and is inserted into the insertion hole.
[0016] Using the above scheme, the second limiting pin can be inserted into the insertion hole after passing through the through hole when the abutment plate is flipped up so that the through hole and the insertion hole are aligned, thereby restricting the abutment plate from flipping up.
[0017] Preferably, when the end of the abutment plate that abuts against the spring clip is flipped away from the spring clip and is limited by the second limiting component, the top surface of the abutment plate is flush with the top surface of the assembly cover, and the assembly cover is provided with an operation groove near the groove to facilitate the operator to flip the abutment plate in the groove.
[0018] By adopting the above solution, the top surface of the abutment plate is set to be flush with the top surface of the assembly cover when the abutment plate is flipped to be limited by the second limiting component. This can further reduce the probability of accidental damage to the abutment plate stored in the groove. The operating slot set on one side of the groove can facilitate the operator to flip the abutment plate stored in the groove.
[0019] This utility model, by adopting the above technical solution, has significant technical effects: the limiting plates set on both sides of the assembly cover can be inserted into the limiting slots on both sides of the mounting groove of the mating cover when the assembly cover is installed onto the mating cover, thereby achieving horizontal limiting between the assembly cover and the mating cover, reducing the probability of abnormal noise during use of the plastic protective cover. At the same time, since the horizontal limiting between the assembly cover and the mating cover is achieved through the insertion between the limiting plate and the limiting slot, and the limiting plate and the limiting slot have a low probability of deformation after long-term use, the service life of the plastic protective cover is improved.

[0031] Example
[0032] A BDU plastic protective cover, reference Figure 5 , Figure 7 , Figure 9 The assembly includes a mating cover 1, an assembly cover 2, and an assembly structure for assembling the two. The assembly structure includes a horizontal limiting component that limits the horizontal direction of the assembly cover 2 after it is installed onto the mating cover 1, and a vertical limiting component that limits the vertical direction of the assembly cover 2 after it is installed onto the mating cover 1. The horizontal limiting component includes an installation groove 8 recessed on one side of the mating cover 1 for the assembly cover 2 to be inserted into, limiting slots 9 respectively provided on the side walls of the installation groove 8, and limiting plates 10 respectively provided on both sides of the assembly cover 2, which are inserted into the limiting slots 9 when the assembly cover 2 is installed into the installation groove 8 to limit the horizontal direction of the assembly cover 2. At least one pair of limiting plates 10 are provided on both sides of the assembly cover 2, and the number and position of the limiting slots 9 provided on both sides of the installation groove 8 correspond one-to-one with the number and position of the limiting plates 10. In this embodiment, two pairs of limiting plates 10 are provided on both sides of the assembly cover 2.
[0033] refer to Figures 5-9The vertical limiting component includes a spring clip 11 disposed on one side wall of the assembly cover 2, a latching block 12 protruding from the side of the spring clip 11 away from the assembly cover 2, and a latching groove 13 disposed in the mounting groove 8 for inserting the latching block 12 and for its top to abut against the top surface of the latching block 12. A deformation limiting component is provided on the assembly cover 2 to reduce the probability that the latching block 12 will dislodge from the latching groove 13 due to deformation of the spring clip 11. In this embodiment, the assembly cover 2 is provided with a deformation-resistant component for the spring clip 11. The groove 22 and the deformation limiting component include a groove 14 provided on the top surface of the mounting cover 2. The mounting groove 8 is provided with abutment plate 15, which abuts against the spring clip 11 at one end after being flipped and limits the deformation of the spring clip 11. The mounting groove 8 is provided with a first limiting component that limits the position of the abutment plate 15 when it is flipped to abut against the spring clip 11 at one end, and a second limiting component that limits the position of the abutment plate 15 when the end of the abutment plate 15 that abuts against the spring clip 11 is flipped away from the spring clip 11.
[0034] The first limiting component includes a first semi-circular hole 16 provided on one side wall of the abutment plate 15, a second semi-circular hole 17 provided on one side wall of the groove 14, which, when the abutment plate 15 is flipped to abut against the spring clip 11, assembles with the first semi-circular hole 16 to form a single limiting hole, and a first limiting pin that is inserted into both the first semi-circular hole 16 and the second semi-circular hole 17 when one end of the abutment plate 15 abuts against the spring clip 11; the second limiting component includes a through hole 19 vertically provided on the abutment plate 15, and a through hole 19 provided on the bottom surface of the groove 14, which, when the end of the abutment plate 15 abuts against the spring clip 11, flips away from the spring clip 11. The insertion hole 20 is directly opposite the through hole 19, and the second limiting pin is inserted into the insertion hole 20 after passing through the through hole 19. In this embodiment, the limiting hole formed by the first semi-circular hole 16 and the second semi-circular hole 17 is the same size as the through hole 19 on the abutment plate 15. The first limiting pin and the second limiting pin are the same pin 18. When the abutment plate 15 is flipped to abut against the spring clip 11 at one end, the pin 18 is inserted into the limiting hole formed by the first semi-circular hole 16 and the second semi-circular hole 17. When the abutment plate 15 is flipped to be housed in the groove 14, the pin 18 passes through the through hole 19 and is inserted into the insertion hole 20.
[0035] When the end of the abutment plate 15 that abuts against the spring clip 11 is flipped away from the spring clip 11 and is limited by the second limiting component, the top surface of the abutment plate 15 is flush with the top surface of the assembly cover 2, and the assembly cover 2 is provided with an operation groove 21 near the groove 14 to facilitate the operator to flip the abutment plate 15 in the groove 14.
[0036] Specific installation process: When the assembly cover 2 needs to be installed onto the mating cover 1, firstly, move the assembly cover 2 directly above the mounting groove 8. Then, align the limiting plates 10 on both sides of the assembly cover 2 with the limiting slots 9 on the mating cover 1 and install the assembly cover 2 into the mating cover 1. When the assembly cover 2 is installed into the mounting groove 8, the spring clip 11 on the assembly cover 2 will abut against the side wall of the mounting groove 8. The spring clip 11 will deform as the assembly cover 2 is installed, thereby driving the locking block 12 on the spring clip 11 away from the mating cover 1. When the assembly cover 2 descends to the point where the locking block 12 on the spring clip 11 engages with the locking block 12, the assembly cover 2 continues to move away from the mating cover 1. When the slot 13 is aligned, the spring clip 11 will recover due to its elastic deformation, thereby allowing the snap-fit block 12 to be inserted into the snap-fit slot 13. After the limiting plate 10 is inserted into the bottom of the limiting slot 9, the pin 18 is pulled out from the through hole 19. Then, the abutment plate 15 is flipped so that one end abuts against the surface of the spring clip 11. At this time, the first semi-circular hole 16 and the second semi-circular hole 17 will fit together to form an integral limiting hole. Then, the pin 18 can be inserted into the limiting hole to keep the abutment plate 15 abutting against the spring clip 11, thereby realizing the overall assembly between the mating cover 1 and the assembly cover 2.
