Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heavy-duty truck coolers, specifically a sealing strip structure for heavy-duty truck coolers. Background Technology
[0002] In the field of traditional heavy-duty truck cooler seals, common sealing methods rely on simple rubber rings or gaskets. Heavy-duty trucks operate under complex conditions daily, experiencing severe vibrations due to road bumps, which continuously impact the cooler seal structure. The engine compartment is constantly exposed to high temperatures, especially during heavy-load transport or prolonged high-speed driving, where the temperature can far exceed the optimal operating temperature range for rubber and gaskets. Simultaneously, various additives in the coolant can chemically corrode the contacting rubber rings and gaskets during circulation.
[0003] Under the combined influence of the aforementioned adverse factors, rubber rings and gaskets are prone to aging after a period of use, resulting in a significant reduction in elasticity and a gradual increase in brittleness. Aged gaskets are easily deformed under vibration and impact, compromising their sealing shape and reducing their fit with inlet, outlet, and connecting pipes. Wear also intensifies over time, smoothing out the fine structure of the sealing surface and leading to decreased sealing performance. Once the sealing performance is reduced, there is a significant risk of coolant leakage.
[0004] When coolant leaks, the amount of coolant in the cooling system becomes insufficient, failing to adequately dissipate the heat generated by the engine. This significantly reduces cooling effectiveness and can lead to engine overheating. Prolonged overheating can cause internal components to expand, deform, or even burn, resulting in severe damage. This not only severely impacts vehicle operation but can also render critical components like the engine unusable, necessitating expensive repairs and replacements. This significantly increases maintenance costs, forces vehicles to remain out of service due to prolonged repairs, delays transportation operations, and causes indirect economic losses.

[0010] Preferably, the top end of the first limiting rod is fixedly connected to the bottom of the second fixing plate near the right side. The top right side of the arc-shaped clamping plate has a hole that matches the first limiting rod, and the arc-shaped clamping plate is slidably connected to the surface of the first limiting rod through the hole. The first limiting rod limits the two arc-shaped clamping plates, so that the two arc-shaped clamping plates move towards each other as the bidirectional screw rotates.
[0011] Preferably, the extrusion mechanism includes guide rods, which are symmetrically arranged on the front side of the first fixed plate. A sliding ring is fixedly connected to the front end of the guide rod, and a fixed ring is provided at the rear end of the guide rod.

[0014] Compared with the prior art, this utility model provides a sealing strip structure for a heavy-duty truck cooler, which has the following advantages:
[0015] 1. This heavy-duty truck cooler uses a sealing strip structure. The sealing sleeve tightly fits into the sealing groove and adheres to the inner wall of the connecting pipe, forming the first effective sealing line. This prevents coolant leakage, ensures the normal operation of the cooling system, and reduces the decrease in cooling efficiency and potential engine overheating caused by coolant leakage. A two-way screw drives the arc-shaped clamps to move in opposite directions, further tightening the connection between the connecting pipe and the inlet and outlet pipes of the cooler body, enhancing the reliability of the seal. This combination of multiple sealing measures improves the sealing performance of the entire cooler system. Compared to traditional sealing strip structures, it better adapts to the complex operating conditions of heavy-duty trucks, reduces the need for frequent maintenance due to poor sealing, and improves vehicle efficiency and reliability.
[0016] 2. The heavy-duty truck cooler uses a sealing structure. The screw and guide rod in the extrusion mechanism allow the operator to adjust the position of the fixing ring by rotating the second crank, thereby applying pressure to the sealing sleeve and further optimizing the sealing effect. Simultaneously, the limiting function of the guide rod and the second limiting rod ensures the stability and accuracy of the adjustment process, allowing the operator to precisely control the extrusion force and position, improving the precision of installation and adjustment.

[0028] This utility model provides the following technical solution:
[0029] Example 1
[0030] Please see Figure 1-5 This utility model provides a technical solution: a sealing strip structure for a heavy truck cooler, including a cooler body 1, a connecting pipe 2 sleeved on the surface of the inlet pipe and outlet pipe of the cooler body 1, a sealing mechanism 3 provided on the surface of the inlet pipe and the surface of the outlet pipe of the cooler body 1, and a squeezing mechanism 4 provided on the back of the sealing mechanism 3.
[0031] The sealing mechanism 3 includes a sealing groove 31, which is formed on the surface of the inlet pipe and the outlet pipe in the cooler body 1. A sealing sleeve 32 is fitted inside the sealing groove 31. A first fixing plate 33 is fixedly connected to the surface of the inlet pipe and the outlet pipe in the cooler body 1. A second fixing plate 34 is fixedly connected to the top of the first fixing plate 33. A third fixing plate 35 is fixedly connected to the bottom of the first fixing plate 33. A bidirectional screw 36 is rotatably connected to the bottom of the second fixing plate 34 near the left side. An arc-shaped clamping plate 37 is symmetrically threaded on the surface of the bidirectional screw 36. A first crank 38 is fixedly connected to the top of the bidirectional screw 36. A first limiting rod 39 is fixedly connected to the bottom of the second fixing plate 34 near the right side.
[0032] The sealing sleeve 32 is located inside the connecting pipe 2 and fits against the inner wall of the connecting pipe 2.
[0033] The top of the third fixing plate 35 is provided with a hole near the left side that matches the bidirectional lead screw 36, and the surface of the bidirectional lead screw 36 passes through and is rotatably connected to the hole.
[0034] The top end of the first limiting rod 39 is fixedly connected to the bottom of the second fixing plate 34 near the right side. The top right side of the arc-shaped clamping plate 37 has a hole that matches the first limiting rod 39, and the arc-shaped clamping plate 37 is slidably connected to the surface of the first limiting rod 39 through the hole. The first limiting rod 39 limits the two arc-shaped clamping plates 37, so that the two arc-shaped clamping plates 37 move towards each other as the bidirectional lead screw 36 rotates.
[0035] Example 2
[0036] Please see Figure 6-7 Furthermore, based on Example 1, the extrusion mechanism 4 is obtained.
[0037] The extrusion mechanism 4 includes a guide rod 41, which is symmetrically arranged on the front of the first fixed plate 33. A sliding ring 42 is fixedly connected to the front end of the guide rod 41, and a fixed ring 43 is provided at the rear end of the guide rod 41. A lead screw 44 is rotatably connected to the back of the first fixed plate 33. A second crank 45 is fixedly connected to the rear end of the lead screw 44. A second limiting rod 46 is fixedly connected to the back of the first fixed plate 33.
[0038] The first fixing plate 33 has holes on the left and right sides of its front side that match the guide rod 41, and the guide rod 41 is slidably connected to the hole through the surface of the plate. The fixing ring 43 has a threaded hole on its front side that matches the lead screw 44, and the fixing ring 43 is threadedly connected to the surface of the lead screw 44 through the threaded hole.
[0039] The fixed ring 43 has a hole on its front side that matches the second limiting rod 46. The fixed ring 43 is slidably connected to the surface of the second limiting rod 46 through the hole. The second limiting rod 46 limits the fixed ring 43, so that the fixed ring 43 moves back and forth as the lead screw 44 rotates.
[0040] In actual operation, when this device is used, the sealing sleeve 32 is pre-installed in the sealing groove 31 on the surface of the inlet and outlet pipes of the cooler body 1 and is located inside the connecting pipe 2. When the connecting pipe 2 is sleeved on the surface of the inlet and outlet pipes, the sealing sleeve 32 fits tightly with the inner wall of the connecting pipe 2, forming the first physical sealing barrier to prevent coolant leakage. Rotating the first crank 38 drives the bidirectional screw 36 to rotate. The upper and lower symmetrical threads on the surface of the bidirectional screw 36 drive the two arc-shaped clamps 37 to move towards each other along the first limiting rod 39. The arc-shaped clamps 37 gradually clamp the outer wall of the connecting pipe 2. Through the squeezing action, the fit between the sealing sleeve 32 and the inner wall of the connecting pipe 2 is enhanced, forming the second mechanical sealing barrier. The first limiting rod 39 ensures that the arc-shaped clamps 37 slide only in the vertical direction to avoid displacement.
[0041] The guide rod 41 is symmetrically fixed to the front of the first fixed plate 33. The front end is connected to the sliding ring 42 and the rear end is connected to the fixed ring 43. The guide rod 41 passes through the hole of the first fixed plate 33 and is slidably connected to ensure that the fixed ring 43 moves only back and forth along the axis of the guide rod 41. Rotating the second crank 45 drives the lead screw 44 to rotate. The thread on the surface of the lead screw 44 drives the fixed ring 43 to move back and forth along the guide rod 41. The second limiting rod 46 passes through the hole of the fixed ring 43 and is slidably connected to prevent the fixed ring 43 from rotating and ensure that the movement direction is stable. When the fixed ring 43 moves forward, it pushes the sliding ring 42 and the sealing sleeve 32 to apply pressure to the inner wall of the connecting pipe 2 through the guide rod 41, further compressing the sealing sleeve 32 and improving its sealing performance. The extrusion mechanism 4 cooperates with the arc-shaped clamp 37 of the sealing mechanism 3 to form a double extrusion effect, ensuring that the sealing sleeve 32 remains tightly fitted under complex working conditions such as vibration and thermal expansion and contraction.
