Description

Technical Field

[0001] The utility model relates to the technical field of charger shells, in particular to a car charger shell. Background Art

[0002] The car charger, also known as the GCA series charger and silicon rectifier charger, is a relatively convenient portable charging tool. The battery can be charged without being disassembled. It is safe to use, has a fast charging speed and strong applicability. It has a high electrical conversion rate and can minimize power loss. It consists of a casing, an engine and a transmission line. The casing is made of sheet metal and is coated with insulating paint.

[0003] At present, the existing car chargers are assembled with an upper shell and a lower shell. When the upper shell and the lower shell are not aligned, a lot of time is needed to adjust them. They can only be fixed after they are completely overlapped. In addition, most car charger shells are fixed by screw threaded holes. Tools are needed for installation and disassembly, and the flexibility is relatively poor.

[0004] To this end, we propose a car charger housing. Utility Model Content

[0005] The main purpose of the utility model is to provide a car charger shell, in order to enhance the fixing effect of the upper shell and the lower shell, and to facilitate the installation and removal of the car charger shell, improve the convenience of the device, and effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A car charger shell, comprising an upper shell and a lower shell, wherein the upper shell is buckled and connected to the inside of the lower shell, and both inner walls of the lower shell are provided with stoppers, wherein four groups of stoppers are provided, and the stoppers include a fixing plate, a threaded rotating rod, a gear, a rack, an insert rod, a first stopper and a locking nut, and a protrusion is fixedly connected to the middle of the inner walls of both ends of the lower shell;

[0008] The bottom end of the upper shell is fixedly connected with a connecting frame, and the middle parts of the inner walls at both ends of the connecting frame are fixedly connected with second limiting blocks arranged oppositely, and the second limiting blocks are provided with symmetrical and staggered limiting grooves on one side close to the connecting frame.

[0009] By adopting the above technical solution, the upper shell is buckled and connected to the lower shell, so that the upper shell and the lower shell overlap, and then the four groups of limiters are controlled in sequence, and at the same time, the threaded rotating rod is rotated to drive the gear to rotate. Due to the meshing of the gear and the rack, the two groups of racks drive the two groups of plug rods to move in opposite directions, and finally the first limit blocks are squeezed away from each other into the limit groove of the upper shell. Finally, the threaded rotating rod is fixed with one hand, and the locking nut is continuously rotated with the other hand to make it move downward continuously until it contacts the outer walls at both ends of the lower shell. At this time, the locking nut is fixed without rotating, and the locking work is completed. The upper shell and the lower shell can be fixed without using tools, thereby improving the convenience of installing and removing the car charger shell;

[0010] It should be noted that the connection frame is located at one end of the fixing plate and is limited between the gear and the rack, and the width of the protrusion is greater than the width of the fixing plate.

[0011] Furthermore, the gear is fixedly connected to the outer side of one end of the threaded rotating rod, and the other end of the threaded rotating rod passes through the lower shell and is threadedly connected to the locking nut.

[0012] Furthermore, the top and bottom ends of the gear are both meshed with the rack, the racks are symmetrical and staggered, and one end of the rack close to the fixed plate is fixedly connected to one end of the insertion rod.

[0013] Furthermore, the other end of the insertion rod passes through the fixing plate and is fixedly connected to a first limiting block, and the first limiting block is adapted to the limiting groove in size.

[0014] Furthermore, a groove is provided between adjacent second limit blocks, and the groove is clamped on the outside of the protrusion.

[0015] By adopting the above technical solution, the groove on the inner side of the second limiting block is clamped to the outside of the protrusion, and at the same time, the fixing plate close to the protrusion is clamped to the outside of the second limiting block.

[0016] Furthermore, a handle is fixedly installed on the upper end surface of the upper shell, and the lower shell is a horizontally arranged rectangular box structure, and supporting legs are fixedly installed at the four corners of the lower shell.

[0017] By adopting the above technical solution, the arrangement of the handle facilitates the movement of the car charger housing, and the supporting legs improve the stability of the car charger housing when it is placed.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] (1) The utility model provides a car charger shell, wherein the upper shell is snap-fitted into the lower shell, at which time the groove on the inner side of the second limit block is snapped onto the outer side of the protrusion, and at the same time the fixing plate close to the protrusion is snapped onto the outer side of the second limit block, so that the upper shell overlaps with the lower shell, further limiting the position of the car charger shell, thereby preventing the upper shell and the lower shell from being difficult to align, and achieving a better fixing effect.

[0020] (2) The utility model provides a car charger shell, which sequentially controls four groups of limiters, and at the same time, rotates the threaded rotating rod to drive the gear to rotate. Due to the meshing of the gear and the rack, the two groups of racks drive the two groups of plug rods to move in opposite directions, and finally the first limit blocks are squeezed away from each other into the limit groove of the upper shell. Finally, one hand fixes the threaded rotating rod, and the other hand continuously rotates the locking nut to make it move downward until it contacts the outer walls at both ends of the lower shell. At this time, the locking nut cannot rotate and completes the locking work. The upper shell and the lower shell can be fixed without using tools, thereby improving the convenience of installing and removing the car charger shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The bottom end of the upper shell 1 is fixedly connected to a connecting frame 12, and the middle parts of the inner walls at both ends of the connecting frame 12 are fixedly connected to second limiting blocks 13 that are relatively arranged, and the second limiting blocks 13 are provided with symmetrical and staggered limiting grooves 15 on the side close to the connecting frame 12.

[0030] When in use, the upper shell 1 is snap-fitted and connected to the lower shell 2, so that the upper shell 1 overlaps with the lower shell 2, and then the four groups of limiters 3 are manipulated in sequence, and at the same time, the threaded rotating rod 6 is rotated to drive the gear 7 to rotate. Since the gear 7 is meshed with the rack 8, the two groups of racks 8 drive the two groups of plug rods 9 to move in opposite directions, and finally the first limit blocks 10 are squeezed away from each other into the limit groove 15 of the upper shell. Finally, the threaded rotating rod 6 is fixed with one hand, and the locking nut 11 is continuously rotated with the other hand to make it move downward continuously until it contacts the outer walls at both ends of the lower shell 2. At this time, the locking nut 11 is fixed without rotating to complete the locking work. The upper shell 1 and the lower shell 2 can be fixed without using tools, thereby improving the convenience of installing and removing the car charger shell;

[0031] It should be noted that the connection frame 12 is located at one end of the fixing plate 5 and is limited between the gear 7 and the rack 8 , and the width of the protrusion 4 is greater than the width of the fixing plate 5 .

[0032] In order to further limit the upper shell 1 and the lower shell 2, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the utility model also includes that the gear 7 is fixedly connected to the outer side of one end of the threaded rotating rod 6, and the other end of the threaded rotating rod 6 passes through the lower housing 2 and is threadedly connected with the locking nut 11;

[0033] The top and bottom ends of the gear 7 are meshed with the rack 8, the racks 8 are symmetrical and staggered, and one end of the rack 8 close to the fixing plate 5 is fixedly connected to one end of the insertion rod 9;

[0034] The other end of the insertion rod 9 passes through the fixing plate 5 and is fixedly connected to the first limiting block 10. The first limiting block 10 is adapted to the limiting groove 15 in size.

[0035] A groove 14 is provided between the adjacent second limiting blocks 13 , and the groove 14 is clamped on the outside of the protrusion 4 .

[0036] When in use, the groove 14 on the inner side of the second limiting block 13 is clamped on the outer side of the protrusion 4 , and at the same time, the fixing plate 5 close to the protrusion 4 is clamped on the outer side of the second limiting block 13 .

[0037] For example, Figure 1 , Figure 2 As shown, the utility model further includes that a handle 16 is fixedly installed on the upper end surface of the upper shell 1, and the lower shell 2 is a horizontally arranged rectangular box structure, and support legs 17 are fixedly installed at the four corners of the lower shell 2.

[0038] When in use, the handle 16 facilitates the movement of the car charger housing, and the support legs 17 improve the stability of the car charger housing when it is placed.

[0039] It should be noted that the utility model is a car charger shell. When in use, the upper shell 1 is snap-fitted and connected to the lower shell 2. At this time, the groove 14 on the inner side of the second limit block 13 is clamped on the outside of the protrusion 4, and the fixing plate 5 close to the protrusion 4 is clamped on the outside of the second limit block 13, so that the upper shell 1 coincides with the lower shell 2, and then the four groups of limiters 3 are manipulated in sequence, and at the same time, the threaded rotating rod 6 is rotated to drive the gear 7 to rotate. Since the gear 7 is meshed with the rack 8, the two groups of racks 8 drive the two groups of plug rods 9 to move in opposite directions, and finally the first limit blocks 10 are squeezed away from each other into the limit groove 15 of the upper shell. Finally, the threaded rotating rod 6 is fixed with one hand, and the locking nut 11 is continuously rotated with the other hand to make it move downward continuously until it contacts the outer walls at both ends of the lower shell 2. At this time, the locking nut 11 is unable to rotate to complete the locking work. The upper shell 1 and the lower shell 2 can be fixed without using tools, thereby improving the convenience of installing and removing the car charger shell.
