Description

Technical Field

[0001] The present application relates to the technical field of combined sheet metal parts, and in particular to a combined sheet metal part. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car body), etc. Its notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts.

[0003] However, in practical applications, most of the existing modular sheet metal parts are usually composed of two or more sheet metal plates that are clamped together and then fastened with screws to achieve a combined effect. However, the screw fastening method is cumbersome to operate and wastes a lot of time. In addition, the screws are prone to loosening after long-term use, which in turn reduces the stability of the connection.

[0004] Therefore, those skilled in the art provide a combined sheet metal component to solve the problems raised in the above background technology. Utility Model Content

[0006] A combined sheet metal part provided in the present application adopts the following technical solution: it includes a lower sheet metal part and an upper sheet metal part, the top sides of the left and right side walls of the lower sheet metal part are fixedly connected with connecting slide rods, the bottom side of the upper sheet metal part is provided with two connecting slide grooves, the two connecting slide rods correspond to the two connecting slide groove boxes respectively, the top side of the lower sheet metal part is provided with four limit holes, the top side of the upper sheet metal part is provided with four countersunk holes, and the inner walls of the four countersunk holes are slidably connected with limit pins.

[0007] Preferably, the top inner walls of the four limit pins are all fixedly connected with nebulium magnetic ring pieces.

[0008] Preferably, the top sides of the four limit pins are rotatably connected with pull rings.

[0009] Preferably, the outer surfaces of the four limit pins are provided with conveying threads, and the bottom ends of the four limit pins are chamfered.

[0010] Preferably, the inner walls of the four sides of the lower sheet metal component are fixedly connected with a same rectangular sealing strip, and the rectangular sealing strip is flush with the top side of the lower sheet metal component.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. By setting the sliding rod and the limit pin, when the lower sheet metal and the upper sheet metal are combined, the connecting slide groove is slid from one end of the connecting slide rod until the two are completely overlapped. At this time, the two are in a clamping state. The columnar design of the slide rod can prevent slipping during the pulling process. At the same time, when the two are completely overlapped, the limit pin on the upper sheet metal will fall into the limit hole, thereby limiting the forward and backward movement direction of the upper sheet metal. In this way, the combination operation between the two sheet metal parts can be completed. Compared with the method of tightening with multiple screws, it can effectively reduce tediousness, save time, and avoid the occurrence of reduced stability after long-term use.

[0013] 2. By setting the rubidium magnetic ring sheet, when the limit pin is inserted into the limit hole, the limit pin will sink into the countersunk hole. At this time, the suction force of the rubidium magnetic ring sheet can make the top inner wall of the limit pin and the bottom inner wall of the countersunk hole fit together, thereby avoiding slippage between the limit pin and the limit hole, and further ensuring the stability of subsequent use.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The present application embodiment discloses a combined sheet metal part, referring to Figure 1-3, including a lower sheet metal part 1 and an upper sheet metal part 2, the top sides of the left and right side walls of the lower sheet metal part 1 are fixedly connected with connecting slide bars 7, the bottom side of the upper sheet metal part 2 is provided with two connecting slide grooves, the two connecting slide bars 7 correspond to the two connecting slide groove boxes respectively, the top side of the lower sheet metal part 1 is provided with four limit holes, the top side of the upper sheet metal part 2 is provided with four countersunk holes, and the inner walls of the four countersunk holes are slidably connected with limit pins 3; by setting the slide bar 7 and the limit pin 3, when the lower sheet metal part 1 and the upper sheet metal part 2 are combined, the connecting slide groove is moved from one end of the connecting slide bar 7 to the upper side of the connecting slide groove. The two are slidably connected until they completely overlap, at which point they are in a locked state, and the columnar slide bar 7 can prevent slipping during the pulling process. At the same time, when the two completely overlap, the limit pin 3 on the upper sheet metal part 2 will fall into the limit hole, thereby limiting the forward and backward movement direction of the upper sheet metal part 2, thereby completing the combination operation between the two sheet metal parts. Compared with the method of tightening with multiple screws, it can effectively reduce tediousness, save time, and avoid the occurrence of reduced stability after long-term use.

[0020] In the present application, the top inner walls of the four limit pins 3 are fixedly connected with a rubidium magnetic ring piece 4; by setting the rubidium magnetic ring piece 4, when the limit pin 3 is inserted into the limit hole, the limit pin 3 will be immersed in the countersunk hole. At this time, the suction force of the rubidium magnetic ring piece 4 can be used to make the top inner wall of the limit pin 3 and the bottom inner wall of the countersunk hole fit together, thereby avoiding slippage between the limit pin 3 and the limit hole, and further ensuring the stability of subsequent use.

[0021] In the present application, the top sides of the four limit pins 3 are rotatably connected with pull rings 5; by providing the pull rings 5, the limit pins 3 can be easily pulled out upwards using the pull rings 5, which is convenient for subsequent disassembly and improves the convenience of use. After the pull rings 5 ​​are flipped over and fit with the limit pins 3, they are at the same horizontal height as the top side of the upper sheet metal part 2.

[0022] In the present application, the outer surfaces of the four limit pins 3 are all provided with conveying threads, and the bottom ends of the four limit pins 3 are all chamfered; by setting the outer surfaces of the limit pins 3 to be provided with conveying threads, when the interior of the limit hole is easily caused to remain dust after long-term use, at this time, the rotating limit pin 3 can use the conveying threads on the surface to get the remaining dust stuck between the threads when rotating, and then the limit pin 3 can be pulled upward to clean out the remaining dust, thereby ensuring that the limit pin 3 fits the limit hole.

[0023] In the present application, the inner walls of the four sides of the lower sheet metal 1 are fixedly connected with the same rectangular sealing strip 6, and the rectangular sealing strip 6 is flush with the top side of the lower sheet metal 1; by setting the rectangular sealing strip 6, after the lower sheet metal 1 and the upper sheet metal 2 are combined, the rectangular sealing strip 6 can be used to improve the sealing of the contact position between the two, thereby improving the scope of application.

[0024] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0025] The implementation principle of a combined sheet metal part in the embodiment of the present application is as follows: during use, when the lower sheet metal part 1 and the upper sheet metal part 2 are combined, the connecting slide groove is slid from one end of the connecting slide rod 7 until the two are completely overlapped. At this time, the two are in a clamping state. The columnar slide rod 7 can avoid slipping during the pulling process. At the same time, when the two are completely overlapped, the limit pin 3 on the upper sheet metal part 2 will fall into the limit hole, thereby limiting the forward and backward movement direction of the upper sheet metal part 2. In this way, the combination operation between the two sheet metal parts can be completed. Compared with the method of tightening with multiple screws, it can effectively reduce tediousness and save time. It can also avoid the situation where stability is reduced after long-term use. When the limit pin 3 is inserted into the limit hole, the limit pin 3 will sink into the countersunk hole. At this time, the suction force of the rubidium magnetic ring piece 4 can make the limit pin The top inner wall of 3 and the bottom inner wall of the countersunk hole fit together, thereby preventing the limit pin 3 from slipping off the limit hole, further ensuring the stability of subsequent use, and using the pull ring 5 to easily pull the limit pin 3 upwards, which is convenient for subsequent disassembly and improves the convenience of use. After the pull ring 5 is turned over and fits with the limit pin 3, it is at the same horizontal height as the top side of the upper sheet metal 2. When the interior of the limit hole is used for a long time, dust is easily left. At this time, the rotating limit pin 3 uses the conveying thread opened on the surface to get the remaining dust stuck between the threads when rotating, and then the limit pin 3 is pulled upward to clean up the remaining dust, thereby ensuring that the limit pin 3 fits the limit hole. After the lower sheet metal 1 and the upper sheet metal 2 are assembled, the rectangular sealing strip 6 can be used to improve the sealing of the contact position between the two, thereby improving the scope of application.
