Description

Technical Field

[0001] This utility model relates to the field of car audio manufacturing, specifically to an installation mechanism that prevents the gas pipe shell of a car audio system from being installed backwards. Background Technology

[0002] The gas pipe housing is an important component of car audio systems. For certain special models, the installation and fixation of the gas pipe housing requires a specially shaped clamp structure. This clamp consists of an upper conical part, a middle disc part, and a lower square disc part. It needs to be fitted into a wing slot on one side of the gas pipe housing, with the disc part positioned above the wing slot and the square disc part below it. However, in actual production, it has been found that the clamp is easily installed backwards, meaning that after installation, the disc part is located below the wing slot and the square disc part is located above it. This situation is not easily noticed and is only discovered during the final assembly. In this case, the gas pipe housing must be reworked separately, which affects the production schedule.

[0003] Furthermore, existing technologies for preventing reverse installation typically design structures tailored to the characteristics of different devices or components. For example, patent CN2462446Y discloses a reverse-installation optical drive front baffle, which, based on the structural features of the optical drive front baffle and chassis, uses single-fold buckles, multi-fold buckles, and asymmetrical two curved surfaces to prevent reverse installation. However, due to the unique shape of the fixing clip used in the gas pipe housing of automotive audio systems, there is no existing technology suitable for preventing the reverse installation of this fixing clip.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] like Figures 1-10 As shown, this utility model includes a cylinder 1, a press-fit push rod 2, a push guide seat 3, and a fixing clamp 4, wherein... Figure 2 and Figure 4 As shown, the propulsion guide seat 3 has a through guide groove along its length, and the two side walls of the guide groove are provided with a guide slope 304, a first limiting protrusion 302, a second limiting protrusion 301, and a second guide groove 305 from top to bottom. A first guide groove 303 is formed between the first limiting protrusion 302 and the second limiting protrusion 301. The fixing clip 4 is disposed in the guide groove, and as shown... Figure 8 As shown, the fixing clip 4 includes a tapered portion 401, a disc portion 402, and a square disc portion 403 arranged sequentially from top to bottom, wherein... Figure 4 As shown, the lower side of the circular portion 402 contacts the guide inclined surface 304 and the first limiting protrusion 302, and the square portion 403 is disposed in the first guide groove 303; the push rod portion 202 of the press-fit push rod 2 is inserted into the guide groove and driven to move by the cylinder 1, wherein... Figure 2As shown, the front end of the push rod portion 202 is provided with an upper pushing portion 2021 and a lower pushing portion 2024, and a receiving groove is formed between the upper pushing portion 2021 and the lower pushing portion 2024. The push rod portion 202 has a first guide protrusion 2023 and a second guide protrusion 2022 arranged sequentially from top to bottom on both sides. When the fixing clamp 4 is pressed in, as... Figure 2 and Figure 4 As shown, the upper pushing part 2021 contacts the conical part 401, the lower pushing part 2024 contacts the square disk part 403, the circular disk part 402 is placed in the receiving slot, the first guide protrusion 2023 slides along the upper surface of the corresponding side first limiting protrusion 302, and the second guide protrusion 2022 moves along the corresponding side second guide groove 305. This utility model, through the structural design of the pushing guide seat 3, ensures that the fixing clip 4 can only be inserted into the guide groove inside the pushing guide seat 3 with the conical part 401 facing upwards, thereby avoiding the fixing clip 4 being installed backwards. Simultaneously, the pressing push rod 2 ensures that the fixing clip 4 is fully pressed in.

[0030] like Figures 1-3 As shown, in this embodiment, the propulsion guide seat 3 is provided with a wing plate positioning seat 7 on the side away from the cylinder 1, and as... Figure 1 As shown, the wing plate positioning seat 7 has a transition surface 702 on the side near the propulsion guide seat 3, such as... Figure 2 As shown, the height of the first guide groove 303 is higher than the transition surface 702, so that the fixing clamp 4 can be placed into the guide groove from the side of the push guide seat 3 away from the cylinder 1.

[0031] like Figure 1 As shown, in this embodiment, the wing plate positioning seat 7 has a positioning platform 701 in the middle, and the positioning platform 701 is higher than the transition surface 702. The positioning platform 701 is provided with a positioning post 6, such as... Figures 5-7 As shown, when this utility model is used, the wing plate 12 to be installed on the gas pipeline shell is placed on the wing plate positioning seat 7, and the positioning post 6 passes through the wing plate 12 to achieve its positioning. The wing plate 12 has a wing plate slot 1201 on the side facing the push guide seat 3 for the insertion of the fixing clip 4. The height of the positioning platform 701 needs to ensure that the fixing clip 4 can be smoothly aligned and inserted into the wing plate slot 1201. At the same time, the height of the transition surface 702 is lower than that of the positioning platform 701. In addition to ensuring that the fixing clip 4 can be placed into the guide groove of the push guide seat 3 before pressing, it can also ensure that the lower end of the fixing clip 4 will not come into contact with the transition surface 702 and cause frictional obstruction when the fixing clip 4 moves along the wing plate slot 1201 during pressing.

[0032] like Figure 1As shown, in this embodiment, the wing plate positioning seat 7 is provided with a marking device 8 on the side away from the propulsion guide seat 3 for marking the wing plate 12 after installation. The marking device 8 is a technology known in the art and is a commercially available product.

[0033] like Figure 1 As shown, in this embodiment, the wing plate positioning seat 7 has a housing support seat 9 on one side in the left-right direction and a positioning and clamping device 5 on the other side, wherein... Figure 5 As shown, the housing 13 of the gas pipeline shell can be fixed to the housing support 9 for positioning. At the same time, the positioning post 6 passes through the wing plate through hole 1202 on the wing plate 12 and is pressed and fixed on the positioning platform 701 by the positioning clamping device 5, thereby ensuring that the wing plate 12 will not move when the fixing clamp 4 is installed.

[0034] like Figure 1 As shown, in this embodiment, the housing support 9 is provided with multiple fixing holes, and the housing 13 part of the gas pipeline shell can be fixed to the fixing holes by bolts. The positioning and pressing device 5 includes a positioning block 502 that is driven to rise and fall by a positioning cylinder 503, and the end of the positioning block 502 is provided with a positioning head 501 that presses the positioning column 6.

[0035] like Figure 1 As shown, in this embodiment, the cylinder 1, the propulsion guide seat 3, the wing plate positioning seat 7, and the positioning and clamping device 5 are all mounted on a bracket 10. The bracket 10 is provided with a cylinder hinge seat 11, and the front end of the cylinder body of the cylinder 1 is rotatably mounted on the cylinder hinge seat 11. The front end of the cylinder rod of the cylinder 1 is provided with a mounting seat 101, and the rear end of the push rod portion 202 of the press-fit push rod 2 is provided with a connecting block 201, which is fixedly connected to the mounting seat 101 by bolts. Figures 9-10 The bracket 10 has a rotating receiving recess 1001 at one end for the cylinder body of the cylinder 1 to rotate into. Through the above structural design, this utility model allows for the replacement of press-fit push rods 2 of different specifications as needed. For example, during replacement... Figures 9-10The cylinder rod of cylinder 1 is fully retracted. Then, the connecting block 201 is first separated from the mounting base 101. Then, the front end of cylinder 1 is rotated upward so that the press-fit push rod 2 has enough space to retract from the push guide seat 3. The cylinder body of cylinder 1 rotates into the rotating receiving recess 1001. Then, the operator removes the original press-fit push rod 2 and puts the new press-fit push rod 2 into the space between cylinder 1 and push guide seat 3. Then, the operator reinserts the new press-fit push rod 2 into the guide groove of push guide seat 3 and moves the new press-fit push rod 2 forward so that the front end of cylinder 1 can rotate and be lowered. Finally, the operator rotates the front end of cylinder 1 downward to restore it to a horizontal state and reconnects the connecting block 201 at the rear end of the new press-fit push rod 2 to the mounting base 101 to complete the replacement.

[0036] Additionally, a pressure sensor can be installed in the mounting base 101 as needed to detect in real time whether the pressing force of the pressing push rod 2 meets the requirements. The pressure sensor is a technology known in the art and is a commercially available product.

[0037] The working principle of this utility model is as follows:

[0038] The following steps are included when using this utility model:

[0039] Step 1: Select press-fit push rod 2.

[0040] Select the appropriate pressing push rod 2 according to the specifications of the fixing clamp 4 to be pressed. The length of the pressing push rod 2 remains unchanged for various specifications. The main difference is whether the structure of the front end upper push part 2021, lower push part 2024, and receiving slot can be matched with the fixing clamp 4 of different specifications.

[0041] Step 2: Install press-fit push rod 2.

[0042] like Figure 10 As shown, the front end of cylinder 1 is rotated upwards and lifted. Then, the selected press-fit push rod 2 is sent below the front end of cylinder 1 and moved forward to insert it into the guide groove on the push guide seat 3. At this time, as shown... Figure 2 As shown, the lower side of the first guide protrusion 2023 on both sides of the press-fit push rod 2 contacts the upper surface of the first limiting protrusion 302 on the corresponding side of the upper end of the push guide seat 3, and at the same time... Figure 2 and Figure 4 As shown, the second guide protrusions 2022 on both sides of the push rod 202 are respectively inserted into the second guide grooves 305 on the corresponding sides of the push guide seat 3. After the press-fit push rod 2 is inserted, the front end of the cylinder 1 is rotated downward to return to a horizontal state, and the connecting block 201 at the rear end of the press-fit push rod 2 is fixedly connected to the mounting seat 101 to complete the installation.

[0043] Step 3: Place the clamp 4 to be pressed into the container.

[0044] like Figure 2 As shown, the fixing clamp 4 to be pressed is fed into the guide groove from the side of the push guide seat 3 away from the cylinder 1, wherein, as shown... Figure 2 and Figure 4 As shown, the lower side of the disc portion 402 of the fixing clamp 4 cooperates with the guide slope 304 at the upper end of the push guide seat 3, and the square disc portion 403 of the fixing clamp 4 is inserted into the first guide groove 303 inside the push guide seat 3.

[0045] Step 4: Insert the gas pipe shell and secure it.

[0046] like Figure 5 As shown, the housing 13 of the gas pipeline shell can be fixed on the housing support 9, and the wing plate 12 is placed on the positioning platform 701 of the wing plate positioning seat 7 and positioned by the positioning post 6 passing through it. The positioning post 6 is pressed by the positioning clamping device 5, thereby ensuring that the wing plate 12 will not move when the fixing clamp 4 is pressed in.

[0047] Step 5: The cylinder 1 starts to drive the press-fit push rod 2 to move, and presses the fixing clamp 4 on the push guide seat 3 into the wing plate slot 1201 on one side of the wing plate 12.

[0048] The present invention ensures that the fixed clamp 4 is not installed backwards when it is inserted through the structural design of the push guide seat 3. Then, the cooperation design of the press-fit push rod 2 ensures that the fixed clamp 4 is press-fitted firmly. At the same time, the structural design of the wing plate positioning seat 7, the shell support seat 9, the positioning column 6, etc. can ensure that the wing plate 12 will not move during press-fitting, and can also avoid friction and jamming at the lower end when the fixed clamp 4 moves along the wing plate slot 1201.

[0049] After the installation or replacement of the press-fit push rod 2 is completed in steps one and two above, steps three to five can be repeated to install each product one by one until the specifications of the fixing clip 4 change.
