Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle sealing devices, specifically relating to a vehicle sealing device for transporting building materials. Background Technology

[0002] Vehicle sealing devices used for transporting building materials are elastic strip-shaped components installed at the joints between the cargo compartment and doors, hatches, etc. of transport vehicles (such as trucks, tankers, etc.).

[0003] Its core function is to fill the gaps between components through its own elastic deformation, thereby achieving a sealing effect. Specifically, it can prevent building materials (such as sand, cement, boards, etc.) from falling out of the gaps due to bumps and vibrations during transportation, while blocking rainwater, dust and other external debris from entering the cargo compartment, protecting building materials from contamination or damage, reducing material loss during transportation, and ensuring transportation safety and efficiency.

[0004] Building material transport vehicles operate in environments with high dust concentrations and complex airflow. Existing sealing devices mostly use a planar sealing structure of "single-layer rubber sealing strip + simple glue bonding". Vibration during vehicle operation can cause the sealing strip to loosen from the mating surface. Traditional sealing strips have poor elasticity and no reinforcing structure. After long-term vibration, they are prone to aging and cracking, and the sealing layer loses its sealing ability. On average, the sealing parts need to be replaced every 3-4 months, resulting in a high maintenance frequency. Utility Model Content

[0005] The purpose of this utility model is to provide a vehicle sealing device for building material transportation, in order to solve the problems in the background art where the operating environment of building material transportation vehicles has high dust concentration and complex airflow. Existing sealing devices mostly adopt a planar sealing structure of "single-layer rubber sealing strip + simple glue bonding". When the vehicle is moving, the vibration will cause the sealing strip to loosen with the contact surface. Traditional sealing strips have poor elasticity and no reinforcing structure. After long-term vibration, they are prone to aging and cracking, and the sealing layer loses its sealing ability. On average, the sealing parts need to be replaced every 3-4 months, resulting in high maintenance frequency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vehicle sealing device for transporting building materials, including a sealing window and a sealing rubber mounting layer disposed at the joint between the sealing window and the outer frame;

[0007] The inner middle side of the sealed window is provided with a hollow sound insulation layer;

[0008] The joint between the sealed window and the sealing rubber mounting layer is filled with an adhesive layer.

[0009] A bottom pad is provided at the bottom of the middle of the sealing rubber mounting interlayer, and a bottom rubber sealing strip is provided on the upper side of the bottom pad;

[0010] The bottom rubber sealing strip has a central hole on its inner side and side holes on the upper left and right sides of its interior. The inner side of the central hole is provided with a desiccant and the inner side of the side holes is provided with a filler adhesive.

[0011] Rubber pads are provided at both ends of the upper side of the bottom rubber sealing strip.

[0012] Preferably, the bottom pad is connected to the sealing rubber mounting interlayer by adhesive bonding, and the bottom rubber sealing strip is connected to the bottom pad by adhesive bonding.

[0013] Preferably, the front and rear ends of the central hole are sealed by covering the bottom with a rubber sealing strip, and the front and rear ends of the two side holes are sealed by covering the bottom with a rubber sealing strip.

[0014] Preferably, the outer side of the sealing rubber mounting interlayer is connected to the external vehicle frame by a snap-fit ​​and mounting method, and the connection is sealed with glue.

[0015] Preferably, the degumming agent is a special degumming agent material for epoxy resin adhesives, and the filler adhesive and adhesive bonding layer material are corresponding decomposable epoxy resin adhesives.

[0016] Preferably, the sealing rubber mounting interlayer extends upward by one centimeter on both sides and wraps around the sealing window, and the bottom of the sealing window has a smooth arc design.

[0017] Compared with the prior art, this utility model provides a vehicle sealing device for transporting building materials, which has the following beneficial effects:

[0018] 1. Building material transport vehicles frequently travel to and from construction sites, sand and gravel pits, and other dusty areas, and often face severe weather conditions such as rain and strong winds. Traditional sealing devices are prone to dust infiltration and rainwater leakage due to gaps and aging of the sealing layer. This not only affects the cab environment and driving safety, but may also contaminate the building materials in the cargo box (such as cement, paint, and other building materials that are easily affected by dust), causing economic losses.

[0019] This device employs an elastic seal with a bottom rubber sealing strip, reinforced with adhesive. The bottom rubber sealing strip itself is highly elastic, adapting to vehicle vibrations and deforming accordingly. It tightly adheres to the sealing rubber mounting interlayer and the surface of the base pad, filling minute gaps during static assembly. Simultaneously, the pre-filled adhesive within the side holes, once activated, forms a complete sealant layer in the gap between the bottom rubber sealing strip and the sealing rubber mounting interlayer. This combination of "elastic sealing" and "adhesive sealing" effectively blocks the path of dust and rainwater seeping in through the interlayer gaps.

[0020] 2. The rubber gasket covers the edge where the bottom rubber sealing strip meets the sealed window. When the sealed window is embedded, the rubber gasket is squeezed and deformed, which can fill the edge gap between the window and the sealing strip. Traditional devices often form "sealing blind spots" due to poor edge fit, while the rubber gasket can specifically seal these blind spots to prevent dust from entering from the edge of the window.

[0021] The interlayer extends upwards on both sides and wraps around the sealed window, forming a double protection of "interlayer wrapping + adhesive bonding". This reduces direct friction and wear between the window and the frame, and prevents dust carried by airflow from seeping in through the joint between the window and the frame. It is especially suitable for complex working conditions such as strong airflow carrying dust in the transportation of building materials, ensuring long-term stable sealing effect.

[0022] 3. Traditional vehicle sealing devices often use an installation method of "on-site glue injection + one-time bonding". This not only requires precise operation by professional personnel (to avoid glue overflow and contamination of parts), resulting in low installation efficiency, but also requires forceful prying and high-temperature heating during disassembly, which can easily damage the windows, frames or sealing components, leading to "replacing the whole set every time it is disassembled", resulting in extremely high maintenance costs. This is a significant pain point for building material transport vehicles that require frequent maintenance (due to dust wear on the seals).

[0023] In this device, the bottom rubber sealing strip is pre-filled with filler glue. During installation, the glue can be activated simply by cutting the edge hole with a knife, eliminating the need for manual mixing and pouring on-site. The operation steps are simplified (ordinary workers can complete the task after simple training). At the same time, the pre-installed design of the bottom pad, bottom rubber sealing strip and sealing rubber installation interlayer means that on-site installation only requires "overall snap-fit ​​+ window pressing", which greatly shortens the installation time of a single set of devices. It is especially suitable for the batch modification needs of building material transportation fleets.

[0024] The central hole is pre-filled with a special adhesive remover for epoxy resin. During disassembly, only a knife is needed to penetrate the wall of the central hole, and the adhesive remover will automatically penetrate to all bonded areas, specifically destroying the adhesive structure. Compared with traditional disassembly methods, no violent operation is required, and core components such as sealed windows, sealed rubber mounting layers, and base pads can be preserved intact, avoiding component damage caused by disassembly. Moreover, the adhesive remover reacts quickly, eliminating the need for long waiting times and significantly reducing maintenance time. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides, for example Figure 1-4 The vehicle sealing device shown includes a sealing window 1 and a sealing rubber mounting layer 3 disposed at the joint between the sealing window 1 and the outer frame.

[0032] A hollow sound insulation layer 2 is provided on the inner side of the middle of the sealed window 1, and an adhesive layer 9 is provided at the connection between the sealed window 1 and the sealing rubber mounting interlayer 3.

[0033] Among them, a bottom pad 5 is provided at the bottom of the middle of the sealing rubber installation interlayer 3, a bottom rubber sealing strip 4 is provided on the upper side of the bottom pad 5, a central hole 10 is provided on the inner side of the middle of the bottom rubber sealing strip 4, and side holes 11 are respectively provided on the upper left and right sides of the bottom rubber sealing strip 4. A desiccant 6 is provided on the inner side of the central hole 10, and a filler adhesive 7 is provided on the inner side of the side holes 11. Rubber pads 8 are respectively provided on the upper left and right ends of the bottom rubber sealing strip 4.

[0034] In this embodiment, during the assembly of the sealing device for building material transportation vehicles, the device completes assembly through a process of "component pretreatment - positioning and installation - sealing reinforcement". First, the sealing window 1 is pretreated. Based on the size and outline of the window opening in the cab or cargo compartment of the building material transportation vehicle, the sealing window 1 is cut and polished to ensure that its shape perfectly matches the window opening. The hollow sound insulation layer 2 is pre-installed on the inner middle side of the sealing window 1. It is integrally formed during the production and processing stage of the sealing window 1, requiring no additional on-site assembly. Only the sealing performance of the hollow sound insulation layer 2 needs to be checked before assembly. Finally, the sealing window 1 is connected and fixed to the sealing rubber mounting interlayer 3: first, in the sealed... Apply adhesive layer 9 evenly to the joint between the sealed window 1 and the sealing rubber mounting interlayer 3 (i.e., the gap area where the two contact). When applying, ensure that the adhesive layer 9 covers the entire joint gap and has a uniform thickness (avoiding excessive thickness leading to overflow or insufficient sealing due to insufficient thickness in some areas). Then, align the sealed window 1 with the preset installation position of the sealing rubber mounting interlayer 3 and slowly press the sealed window 1 to make the sealed window 1 and the sealing rubber mounting interlayer 3 fit tightly together. At the same time, squeeze the adhesive layer 9 to expel the air in the interlayer and ensure that the adhesive layer 9 fills all the tiny gaps. Let it stand until the adhesive layer 9 is completely cured, forming a stable connection between the sealed window 1 and the sealing rubber mounting interlayer 3, and the assembly is complete.

[0035] Preferably, the sealed window 1, as the core component of the vehicle sealing device, functions primarily to block direct communication between the external environment and the vehicle's interior. Building material transport vehicles often operate in dusty and complex environments such as construction sites and sand and gravel pits, and are susceptible to the effects of rain, strong winds, and other natural factors during transport. The sealed window 1, through its tight fit with the vehicle's external frame and the sealing rubber mounting layer 3, forms a physical barrier: on the one hand, it prevents external dust and gravel particles from entering the vehicle interior (avoiding dust adhering to the dashboard or cargo material surfaces, affecting driving safety and material quality); on the other hand, it isolates rainwater and strong winds, preventing rainwater seepage that could cause moisture damage to the cab and electrical components, while also reducing vibration noise generated by strong winds directly impacting the window. Furthermore, the smooth, rounded design at the bottom of the sealed window 1 reduces air resistance as the vehicle moves, minimizing airflow noise, and preventing sharp edges from scratching operators or damaging other components during installation or use.

[0036] Optionally, the hollow sound insulation layer 2 is pre-installed on the inner side of the sealed window 1, and its core principle is based on the mechanisms of "air layer sound insulation" and "sound wave attenuation". When building material transport vehicles are in motion, they will generate various noises such as engine running noise, tire friction noise, and noise from the shaking and collision of building materials in the cargo box. These noises will enter the interior of the vehicle through the windows. When the hollow sound insulation layer 2 is subjected to sound waves, the sound waves first contact the outer wall of the sealed window 1, and some of the sound waves are reflected by the outer wall. When the sound waves entering the window reach the hollow sound insulation layer 2, they undergo multiple reflections and refractions within the air layer. As the sound waves propagate in the air layer, they rub against air molecules, converting mechanical energy into heat energy, which is then dissipated. At the same time, the presence of the air layer breaks the continuous propagation path of the sound waves, significantly weakening their energy. When the remaining small amount of sound waves reaches the inner wall of the window, they are reflected and absorbed again, ultimately achieving effective noise reduction. Simultaneously, the hollow sound insulation layer 2 also has a heat insulation function: when building material transport vehicles operate in summer under direct sunlight or in winter in low temperatures, external high or low temperatures can easily be conducted to the interior through the windows. The air layer in the hollow sound insulation layer 2 is a poor conductor of heat, slowing down the rate of heat conduction—reducing external heat entering the vehicle in summer and lowering the cooling load on the cab; reducing heat loss from the vehicle in winter, maintaining a stable interior temperature, improving driving comfort, and preventing fogging of the windows due to excessive temperature differences, ensuring clear visibility for the driver.

[0037] Optionally, the adhesive layer 9 serves as the connecting medium between the sealed window 1 and the sealing rubber mounting interlayer 3, and its functions are divided into "structural fixation" and "gap sealing." In terms of structural fixation, the adhesive layer 9, after curing, possesses strong bonding strength, firmly connecting the sealed window 1 and the sealing rubber mounting interlayer 3 into a single unit, preventing separation due to vibration during vehicle operation and ensuring the stability of the sealing structure. In terms of gap sealing, the adhesive layer 9 has good fluidity and filling properties. When the sealed window 1 is pressed, it can penetrate into the tiny pores of the connection between the sealed window 1 and the sealing rubber mounting interlayer 3, forming a complete sealing layer after curing. This prevents air, dust, and rainwater from entering the vehicle through the gaps, compensating for any minor gaps that may exist in the physical bonding, and further enhancing the overall sealing effect.

[0038] like Figure 1-4As shown, the base pad 5 is connected to the sealing rubber mounting interlayer 3 by adhesive bonding. The bottom rubber sealing strip 4 is connected to the base pad 5 by adhesive bonding. The front and rear ends of the central hole 10 are sealed by being covered by the bottom rubber sealing strip 4. The front and rear ends of the two side holes 11 are sealed by being covered by the bottom rubber sealing strip 4. The outer side of the sealing rubber mounting interlayer 3 is connected to the external vehicle frame by snap-fit ​​and installation, and the connection is sealed with adhesive. The adhesive release agent 6 is a special adhesive release agent for epoxy resin. The filler adhesive 7 and the adhesive bonding layer 9 are made of the corresponding decomposable epoxy resin adhesive. The sealing rubber mounting interlayer 3 extends one centimeter upward on both sides and wraps around the sealing window 1. The bottom of the sealing window 1 has a smooth arc design.

[0039] Preferably, the innovative structure of this device uses the sealing rubber mounting interlayer 3 as the basic carrier, integrating the bottom pad 5, the bottom rubber sealing strip 4, the adhesive release agent 6, the filler adhesive 7, the rubber gasket 8, and the central hole 10 and the side hole 11 pre-set in the bottom rubber sealing strip 4. Each component forms a functional structure that can achieve "convenient installation" and "quick disassembly" through a specific connection method. Its core advantage lies in solving the pain points of "cumbersome installation" and "difficult disassembly" of traditional vehicle sealing devices, while enhancing the sealing performance.

[0040] The installation of the innovative structure is divided into two stages: "pre-installation of the sealing rubber installation interlayer 3" and "assembly of the whole with the vehicle frame".

[0041] The first stage involves pre-installation inside the sealing rubber mounting interlayer 3. First, apply adhesive evenly to the bottom center of the sealing rubber mounting interlayer 3. Then, fix the base pad 5 to the bottom center of the sealing rubber mounting interlayer 3 by adhering it with adhesive, ensuring that the base pad 5 is completely attached to the bottom of the sealing rubber mounting interlayer 3 without any offset or lifting (the base pad 5 needs to cover the core stress area of ​​the bottom of the sealing rubber mounting interlayer 3 to provide stable support for the subsequent bottom rubber sealing strip 4). Let it stand until the adhesive cures to complete the installation of the base pad 5.

[0042] Then, evenly apply adhesive to the upper side of the base pad 5, align the bottom rubber sealing strip 4 with the preset position of the base pad 5 (ensuring that the central axis of the bottom rubber sealing strip 4 coincides with the central axis of the sealing rubber installation interlayer 3), and slowly press the bottom rubber sealing strip 4 to make it fit tightly against the base pad 5; at this time, pay attention to the central hole 10 and the side hole 11 inside the bottom rubber sealing strip 4—the central hole 10 is located in the middle inner side of the bottom rubber sealing strip 4, and is pre-filled with adhesive release agent 6, and the front and rear ends of the central hole 10 are sealed by the bottom rubber sealing strip 4 itself; the side hole 11 is located on the upper left and right sides inside the bottom rubber sealing strip 4, and is pre-filled with filler adhesive 7, and the front and rear ends are also sealed by the bottom rubber sealing strip 4. During installation, avoid squeezing the bottom rubber sealing strip 4 to prevent the central hole 10 or the side hole 11 from cracking and the internal medium from leaking; let it stand until the adhesive cures to complete the connection between the bottom rubber sealing strip 4 and the base pad 5.

[0043] Apply adhesive to the left and right ends of the upper side of the bottom rubber sealing strip 4, and attach the rubber gasket 8 to the preset position. Ensure that the rubber gasket 8 covers the upper edge area of ​​the bottom rubber sealing strip 4 and fits tightly with the bottom rubber sealing strip 4, thus completing the pre-installation of the innovative component inside the sealing rubber installation interlayer 3.

[0044] The second stage is the overall assembly with the vehicle frame. First, the user can use an external sharp knife (such as a utility knife) to gently scratch the surface of the bottom rubber sealing strip 4 at the position corresponding to the side hole 11 on the outside (the scratch depth should be just enough to penetrate the surface of the bottom rubber sealing strip 4 and contact the side hole 11, to avoid damaging the internal structure of the side hole 11). Then, the knife is inserted into the two side holes 11, and the wall of the side hole 11 is slightly pried to allow the pre-filled filler glue 7 in the side hole 11 to overflow into the gap between the bottom rubber sealing strip 4 and the sealing rubber mounting interlayer 3. After the filler glue 7 overflows, it is necessary to wait for it to initially cure, further strengthening the bonding strength between the bottom rubber sealing strip 4 and the sealing rubber mounting interlayer 3, while filling any possible small gaps.

[0045] Apply sealant to the outside of the sealing rubber mounting layer 3, then connect the sealing rubber mounting layer 3 to the external vehicle frame using a snap-fit ​​method—align the sealing rubber mounting layer 3 with the sliding groove of the vehicle frame and slowly push it into the preset position, ensuring that the outside of the sealing rubber mounting layer 3 is completely flush with the sliding groove of the vehicle frame; at the same time, the upper and lower extensions of the sealing rubber mounting layer 3 on both sides need to wrap around the edge of the sealing window 1 to form a secondary seal; after connection, check the connection between the sealing rubber mounting layer 3 and the vehicle frame. If there are gaps, apply more sealant to ensure that there are no leaks at the connection. To prevent air and water leakage, align the sealed window 1 (with the hollow sound insulation layer 2 integrated and the adhesive layer 9 applied) with the mounting groove of the sealing rubber mounting interlayer 3, and slowly press the sealed window 1 so that it is completely embedded in the sealing rubber mounting interlayer 3, and the sealed window 1 and the sealing rubber mounting interlayer 3 are tightly bonded together by the adhesive layer 9. During the pressing process, the sealed window 1 must be kept horizontal and centered to avoid cracking of the sealed window 1 or the formation of sealing gaps due to uneven force. Let it stand until the adhesive layer 9 and the filler glue 7 are completely cured to complete the installation of the entire sealing device.

[0046] Preferably, when the sealing device needs maintenance or replacement (such as when the sealed window 1 is damaged or the sealing rubber is aged), the innovative structure allows for quick disassembly. The user first pulls the sealed window 1 and the sealing rubber mounting interlayer 3 out of the slide groove of the frame (if the clamping is too tight, the edge of the sealing rubber mounting interlayer 3 can be slightly pried to avoid damage to the parts due to violent pulling).

[0047] Then, insert a knife into the gap of the sealing rubber mounting interlayer 3, aligning it with the central hole 10 of the bottom rubber sealing strip 4, and penetrate the wall of the central hole 10 of the bottom rubber sealing strip 4 (the penetration depth should ensure that the adhesive remover 6 can flow out smoothly); the adhesive remover 6 (a special adhesive remover for epoxy resin) pre-filled in the central hole 10 will flow out along the damaged area and penetrate to key bonding areas such as the adhesive bonding layer 9, the bonding area between the filler adhesive 7 and the bottom pad 5. After standing for a period of time, the adhesive remover 6 will fully react with the adhesive layer (adhesive bonding layer 9, filler adhesive 7, and adhesive bonding area of ​​the bottom pad 5) - the adhesive remover 6 will destroy the high molecular cross-linking structure of the adhesive and weaken the adhesive strength; when the adhesive layer completely loses its adhesive force, the sealing window 1, the sealing rubber mounting interlayer 3, the bottom pad 5 and the bottom rubber sealing strip 4 can be easily separated, and the disassembly is completed; after disassembly, the intact parts can be cleaned and reused according to the damage of the parts, and the damaged parts can be replaced separately.

[0048] Preferably, the operating environment of building material transport vehicles is characterized by high dust and strong vibration, making traditional sealing devices prone to seal failure due to gaps. This device features an innovative structure that enhances overall sealing performance through a multi-dimensional sealing design. The bottom rubber sealing strip 4 is positioned between the sealing rubber mounting layer 3 and the bottom pad 5. It possesses excellent elasticity and deformation capabilities. Vibrations generated during vehicle operation cause the bottom rubber sealing strip 4 to adapt and deform, tightly adhering to the surfaces of the sealing rubber mounting layer 3 and the bottom pad 5, filling the tiny gaps between them. Simultaneously, after the glue 7 overflows from the side holes 11 within the bottom rubber sealing strip 4, it forms a complete sealant layer in the gap between the bottom rubber sealing strip 4 and the sealing rubber mounting layer 3, further preventing dust and rainwater from seeping in through the gaps.

[0049] The rubber gasket 8 is located on the upper left and right ends of the bottom rubber sealing strip 4, covering the edge joint between the bottom rubber sealing strip 4 and the sealed window 1. When the sealed window 1 is embedded in the sealing rubber mounting layer 3, the rubber gasket 8 will be squeezed and deformed to fill the edge gap between the sealed window 1 and the bottom rubber sealing strip 4, avoiding sealing leaks caused by poor edge fit. At the same time, the elasticity of the rubber gasket 8 can buffer the vibration friction between the sealed window 1 and the bottom rubber sealing strip 4, preventing long-term vibration from causing edge seal failure.

[0050] The upper and lower portions of the sealing rubber installation interlayer 3 on both sides wrap around the sealing window 1, forming a double sealing structure of "interlayer wrapping + adhesive bonding". The extended portion can cover the edge area of ​​the sealing window 1, reducing the direct contact between the sealing window 1 and the vehicle frame and avoiding sealing gaps caused by wear on the edge of the window. At the same time, the close fit between the extended portion and the sealing window 1 can further block airflow and dust from intruding from the edge of the window, which is suitable for the sealing requirements of high dust and strong airflow in the construction material transportation scenario.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
