Abstract
Description
Technical Field
[0001] The utility model relates to a through-hole sheath for a cab front panel, belonging to the technical field of automotive parts. Background Art
[0002] The throttle operating system of a national II emission engine uses a mechanical structure. The throttle cable needs to pass through the cab and be connected to the engine cylinder. Usually, a through-hole sheath is required at the through-hole position of the cab. The existing through-hole sheath is clamped into the front panel hole of the cab in the circumferential direction, and the through-hole sheath and the front panel cannot be tightly pressed to form a seal. On the other hand, there is no diversion structure on the outer side of the original through-hole sheath. The water flowing down along the front panel is likely to enter the cab through the gap between the through-hole sheath and the front panel on the one hand, and on the other hand, it is likely to flow onto the surface of the cable and enter the cab interior along the cable. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to provide a through-hole sheath for a cab front panel to ensure that the through-hole sheath is closely attached to the surface of the cab front panel and improve the sealing performance in view of the defects existing in the prior art.
[0004] To solve this technical problem, the utility model provides a through-hole sheath for a cab front panel, including a sheath body. The sheath body is provided with an inner lip, an outer lip, an extension part, a retaining edge and a T-shaped wire threading channel. The middle part of the sheath body is a T-shaped wire threading channel. One end of the T-shaped wire threading channel is provided with an inner lip and an outer lip, and a groove is arranged between the inner lip and the outer lip for fixing the through-hole sheath of the cab front panel.
[0005] The other end of the sheath body is provided with a retaining edge, and the retaining edge is connected to the outer lip through the extension part.
[0006] The distance from the outer edge of the retaining edge to the center line of the T-shaped wire threading channel is 1 cm to 2 cm.
[0007] The length of the extension part is 3 to 5 cm.
[0008] The end of the outer lip is an arc structure.
[0009] The dimension of the outer circle of the outer lip from the center line of the T-shaped wire threading channel is 7.5 to 9.5 mm larger than the dimension of the outer circle of the inner lip from the center line of the T-shaped wire threading channel.
[0010] The distance from the outer edge of the outer lip to the center line of the T-shaped wire threading channel is 10 cm to 15 cm.
[0011] The distance from the outer edge of the inner lip to the center line of the T-shaped wire threading channel is 5 cm to 7.5 cm.
[0012] The sheath body is in interference fit with the cab front panel through the groove.
[0013] A groove is provided circumferentially between the inner lip and the outer lip. The inner lip passes through a hole in the front panel of the cab, and the hole in the front panel of the cab is snapped into the groove of the through-hole sheath. The inner lip is in contact with the inner side surface of the front panel of the cab, and the outer lip is in close contact with the outer side surface of the front panel of the cab. The throttle cable passes through the T-shaped wire threading channel and exits from the inside of the cab.
[0014] Beneficial effects: The utility model can ensure that the through-hole sheath is in close contact with the surface of the front panel, improving the sealing performance. At the same time, it can achieve the function of rainwater separation, ensuring that rainwater cannot enter the cab. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will specifically describe the utility model in conjunction with the drawings and embodiments.
[0019] As Figure 1 and Figure 2 shown, the utility model provides a through-hole sheath for the front panel of a cab, including a sheath body. The sheath body is provided with an inner lip 1, an outer lip 2, an extension part 4, a stop edge 5 and a T-shaped wire threading channel 6. The middle part of the sheath body is a T-shaped wire threading channel 6 for arranging wire harnesses. One end of the T-shaped wire threading channel 6 is provided with an inner lip 1 and an outer lip 2, and a groove 3 is provided between the inner lip 1 and the outer lip 2, which can tightly clamp the through-hole sheath body on the hole of the cab for fixing the through-hole sheath of the front panel of the cab.
[0020] The other end of the sheath body is provided with a stop edge 5. The stop edge 5 is connected to the outer lip 2 through the extension part 4. The stop edge 5 can intercept the rainwater flowing down along the outer lip 2 and guide it away through the extension part, preventing the rainwater from flowing back into the cab interior through the wire threading channel.
[0021] The distance from the outer edge of the stop edge 5 to the center line of the T-shaped wire threading channel 6 is 1 cm to 2 cm (the specific dimensions are set according to the actual situation).
[0022] The length of the extension part 4 is 3 to 5 cm (the specific dimensions are set according to the actual situation).
[0023] The ends of the outer lip 2 and the inner lip 1 are arc-shaped structures. The arc-shaped structure at the end of the outer lip 2 can ensure that the through-hole sheath can be tightly fitted and sealed with the front panel surface, preventing rainwater from flowing into the cab interior.
[0024] The dimension of the outer circle of the outer lip 2 from the center line of the T-shaped wire threading channel 6 is 7.5 - 9.5 mm larger than the dimension of the outer circle of the inner lip 1 from the center line of the T-shaped wire threading channel 6.
[0025] The distance from the outer edge of the outer lip 2 to the center line of the T-shaped wire threading channel 6 is 10 cm - 15 cm (the specific dimension is set according to the actual situation).
[0026] The distance from the outer edge of the inner lip to the center line of the T-shaped wire threading channel is 5 cm - 7.5 cm (the specific dimension is set according to the actual situation).
[0027] The sheath body is in interference fit with the cab front panel through the groove 3.
[0028] A groove 3 is provided circumferentially between the inner lip 1 and the outer lip 2. The inner lip 1 passes through the hole of the cab front panel 7, and the hole of the cab front panel 7 is clamped into the groove 3 of the through-hole sheath. The inner lip 1 is in contact with the inner side surface of the cab front panel 7, and the outer lip 2 is in close contact with the outer side surface of the cab front panel 7, improving the sealing performance of the through-hole sheath. The throttle cable passes through the T-shaped wire threading channel 6 and exits from the cab interior.
[0029] When rainwater flows down from the cab front panel 7, the outer lip 2 can divert the rainwater to both sides of the through-hole sheath. The rainwater flowing along the outer lip 2 is effectively intercepted by the baffle 5, and the rainwater is separated through the extension part 4, preventing the rainwater from flowing back into the cab interior along the inner side of the T-shaped wire threading channel 6.
[0030] The utility model is easy to install, has good sealing performance, and at the same time has a rainwater separation function, solving the problem of rainwater flowing back into the cab interior on rainy days.
[0031] The above embodiments of the utility model are only examples, not the only ones. All changes within the scope of the utility model or equivalent to the scope of the utility model are encompassed by the utility model.
