Description
Technical Field
[0001] The utility model relates to the technical field of motorcycles, and particularly relates to a quick-release belt protection cover fixing structure. Background Technique
[0002] The motorcycle belt protection cover is a protection device designed specifically for motorcycles. Its main function is to cover and protect the belt drive system of the motorcycle, preventing external objects such as dust, stones, water, etc. from entering and damaging the belt or related components. This protection cover is usually made of strong and durable materials such as metal or high-strength plastic to ensure that it can withstand various environmental and condition impacts during the motorcycle's operation.
[0003] Specifically, the design of the motorcycle belt protection cover takes into account the size and shape of the belt to ensure that it can closely fit on the belt and cover the entire working area of the belt. At the same time, the protection cover also adopts appropriate fixing methods such as screws, buckles, etc. to ensure that it can be firmly installed on the motorcycle and will not loosen or fall off during operation.
[0004] In addition to preventing external objects from entering and damaging the belt, the motorcycle belt protection cover also has other important functions. For example, it can reduce the noise and vibration generated by the belt during operation, improving the driving stability and comfort of the motorcycle. In addition, the protection cover can also prevent the belt from aging, cracking or wearing due to long-term exposure to the external environment, thereby extending the service life of the belt.
[0005] The fixing method of the motorcycle belt protection cover usually depends on the specific model and design, but generally speaking, the fixing methods mainly include the following two:
[0006] First, many motorcycle belt protection covers are directly fixed to the engine or other related components by bolts or screws. This method ensures the stability of the protection cover and can withstand the vibration and force during operation. During installation, it is necessary to pre-drill holes in the protection cover and the fixing position and use appropriate bolts or screws for fastening.
[0007] Second, some protection covers may adopt a buckle or strap design to be fixed to the frame. This fixing method is relatively simple, does not require additional drilling operations, and is also convenient for disassembly and replacement. The user only needs to align the protection cover with the fixing position and then fasten the buckle or strap.
[0008] Since motorcycles have excellent passing ability, they often travel on rough unpaved roads. As a transmission vulnerable part on motorcycles, the belt needs to be regularly inspected and maintained to ensure its normal operation. If there is a problem with the belt during the journey, it is necessary to quickly check the condition of the belt and quickly repair it to support the motorcycle to drive to the repair place. When the belt guard is directly fixed by drilling holes in the pre-position and using bolts or riveting, it may not be possible to disassemble the belt guard because the driver does not carry a screwdriver. For a belt guard directly using a buckle or a strap, its fixing method is not reliable. When encountering rough and bumpy roads on the way, the belt guard may be directly shaken off, and the belt may be collided by foreign objects, resulting in accelerated wear or direct damage. Summary of the Invention
[0009] The present invention provides a quick-release fixing structure for a belt guard, which solves the problem in the prior art that when the belt guard is directly fixed by drilling holes in the pre-position and using bolts or riveting, it may not be possible to disassemble the belt guard because the driver does not carry a screwdriver.
[0010] Secondly, for a belt guard directly using a buckle or a strap, due to its unreliable fixing method, when encountering rough and bumpy roads on the way, the belt guard may be directly shaken off, and the belt may be collided by foreign objects, resulting in accelerated wear or direct damage.
[0011] In order to achieve the above object, the present invention adopts the following technical solutions:
[0012] A quick-release fixing structure for a belt guard, including a belt guard, which is an arc-shaped plate structure. An open pin is provided at one end of the outer side surface. The open pin connects the belt guard and the rear protection bracket. A front fixing hook plate is provided at the other end. The front fixing hook plate includes a fixing plate and a hook plate.

[0013] Preferably, a first riveting hole is provided at the edge of one side of the belt guard and is equally distributed along the arc. A CVT guard is also provided on the side of the belt guard where the first riveting hole is located. The belt guard and the CVT guard are fixedly riveted by matching the first riveting holes. A middle shaft hole is provided in the middle of the CVT guard.
[0014] Preferably, the rear protection bracket is a plate structure. A pin hole convex block is provided at one end. A pin position hole is also provided at the end of the end of the belt guard where the open pin is provided. The pin hole convex block matches and passes through the pin position hole, and the open pin is inserted into the pin hole convex block.
[0015] Preferably, both the fixing plate and the hook plate are plate-shaped structures. The hook plate is located on one side of the fixing plate and is perpendicular to the fixing plate. The hook plate and the fixing plate are integrally formed. A plurality of riveting holes II are provided on the fixing plate. The fixing plate is attached to the belt protection cover and is fixedly riveted by means of the riveting holes II.
[0016] Preferably, the front protection bracket is a plate-shaped structure. A plurality of through holes are equidistantly distributed on the surface of the front protection bracket.

The hook groove cooperates with the hook plate, and the hook plate is accommodated in the hook groove.
[0017] Preferably, an intermediate shaft mounting bracket is fixed to the same-side ends of the front fixing hook plate and the rear protection bracket. The intermediate shaft mounting bracket is also provided with a central hole.
[0018] Preferably, the fixing plate and the belt protection cover are fixedly riveted by blind rivets.
[0019] Preferably, a plurality of reinforcing ribs are provided on the belt protection cover and the rear protection bracket.
[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0021] The present utility model includes a split pin and a front fixing hook plate. The belt protection cover is cooperatively connected with the front protection bracket and the rear protection bracket through the split pin and the front fixing hook plate. The split pin can effectively limit the longitudinal displacement of the belt protection cover, and the front fixing hook plate can effectively reduce the lateral displacement of the belt protection cover. The combined cooperation of the split pin and the front fixing hook plate makes the belt protection cover more firmly and stably fixed.

Specific embodiments
[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0028] The fixing method of the motorcycle belt protection cover usually depends on the specific motorcycle model and design. Generally speaking, the fixing methods mainly include the following two types:
[0029] First, many motorcycle belt protection covers are directly fixed to the engine or other related components by bolts or screws. This method ensures the stability of the protection cover and can withstand the vibration and force during operation. During installation, it is necessary to pre-drill holes in the protection cover and the fixing position, and use appropriate bolts or screws for fastening.
[0030] Second, some protection covers may adopt a snap or buckle design to be fixed to the frame. This fixing method is relatively simple, does not require additional drilling operations, and is also convenient for disassembly and replacement. The user only needs to align the protection cover with the fixing position and then fasten the snap or buckle.
[0031] Due to the excellent passing ability of motorcycles, they often travel on rough unpaved roads. As a transmission vulnerable part on motorcycles, the belt needs to be regularly inspected and maintained to ensure its normal operation. If the belt has problems during the journey, it is necessary to quickly check the condition of the belt and quickly repair it to support the motorcycle to drive to the repair place. When the belt protection cover is directly fixed by pre-drilling holes in the pre-position and using bolts or riveting methods, it may not be possible to disassemble the belt protection cover because the driver does not carry a screwdriver. For the belt protection cover directly using snaps or buckles, its fixing method is not reliable. When encountering rough and bumpy roads on the way, the belt protection cover may be directly shaken off, and the belt may be collided by foreign objects, resulting in accelerated wear or direct damage. To solve the above problems, this embodiment is thus provided.
[0032] Refer toFigures 1 to 4 For this embodiment, Figure 1 FIG. 1 is a front view schematic diagram of the overall structure of this embodiment. Figure 2 FIG. 2 is a right view schematic diagram of the overall structure. This embodiment relates to a quick-release belt protection cover fixing structure, which is mainly composed of a belt protection cover. The belt protection cover is designed in an arc-shaped plate as a whole. At one end of its outer side, a split pin is specially provided, which plays a role in connecting the belt protection cover and the rear protection bracket, ensuring the stability of the structure. At the other end, a front fixing hook plate is provided, which is composed of a fixing plate and a hook plate. Among them, the fixing plate is tightly fixed to the belt protection cover, and the hook plate is matched with the front protection bracket, further enhancing the firmness of the whole structure. Through this design, both the stability of the belt protection cover can be ensured and quick disassembly can be realized, improving the use efficiency.
[0033] In addition, for the front fixing hook plate part, a higher-strength alloy material is selected, which not only improves the wear resistance and impact resistance of the hook plate, but also ensures the high precision of the mating surface between the hook plate and the front protection bracket through precise die processing, reducing the loosening problem caused by excessive clearance. At the same time, anti-slip tooth patterns are added inside the front fixing hook plate, which can maintain a stable connection state even under harsh working conditions, effectively preventing accidental detachment caused by vibration or impact.
[0034] Finally, considering the convenience of installation and maintenance, there is a broken opening on the outer periphery of the belt protection cover. The opening design not only increases the installation dimension allowance to suit different specifications of vehicles, but also serves as an observation and maintenance window. This design allows users to directly observe the internal belt and the surrounding area from the bottom of the vehicle without completely removing the protection cover. According to the observation results, the user can decide whether to clean and maintain, effectively extending the service life of the equipment and reducing the risk of wear and damage caused by frequent disassembly.
[0035] At a certain side edge part of the belt protection cover, there are several riveting holes arranged at equal intervals in an arc shape. The main function of these riveting holes is to facilitate the connection with other components. On the side where the riveting holes are provided, a CVT protection cover is specially added. The main function of the CVT protection cover is to further protect the precision components inside the belt protection cover. The fixing method between the two is mainly through the cooperation of the riveting holes with other components and fixed by riveting, ensuring the firmness and stability of the connection. In addition, a middle shaft hole is specially opened at the middle position of the CVT protection cover to meet the passing requirement of the middle shaft and also provide guarantee for the stability and service life of the overall structure.
[0036] The edge of the CVT cover is designed with anti-skid texture, which not only improves the operator's hand grip during maintenance or installation, but also prevents slipping due to improper operation to a certain extent, enhancing the safety of the operation. At the same time, the precise layout of the anti-skid texture also reflects the ultimate pursuit of product details, which complements the industrial aesthetics of the overall design.
[0037] In order to further optimize the heat dissipation performance and ensure the stable operation of the precision parts in the belt protection cover, the surface of the CVT cover adopts advanced heat dissipation coating technology. This coating can not only effectively absorb and quickly dissipate the heat generated by the operation of the parts, but also has excellent corrosion and wear resistance, which prolongs the service life of the cover and reduces maintenance costs.
[0038] In addition, considering the vibration and impact problems that may be encountered in actual working conditions, we added an elastic buffer pad between the CVT guard and the belt guard. This design can not only effectively alleviate the impact of external vibration on internal precision components, but also play a certain buffering role when impacted, protecting the stable operation of the entire system. The selection of the buffer pad material has also been carefully considered. It must have good elastic recovery ability and be able to withstand harsh environments such as high temperature and oil pollution.
[0039] The rear protection bracket is designed in a plate shape, one end of which is provided with a pin hole protrusion for connection with other parts. The structure of the belt protection cover is also quite delicate. At the end of the end where the split pin is provided, a pin hole is specially designed to match the pin hole protrusion. When the pin hole protrusion is correctly aligned with the pin hole and passes through the pin hole, a stable connection can be formed. In addition, the split pin is cleverly inserted inside the pin hole protrusion. This design not only enhances the stability of the structure, but also improves the safety performance during use.
[0040] The surface of the belt protection cover and the rear protection bracket is evenly distributed with a number of reinforcement ribs. These reinforcement ribs are intended to enhance the structural strength and stability of the protection cover and the bracket, ensuring that they can maintain good integrity when subjected to external impact and pressure, thereby providing more reliable protection for the belt.
[0041] In order to ensure a firm and flexible connection, a set of tiny spring washers are embedded at the junction of the pin hole protrusion and the pin hole. These washers play a role of buffering and pre-tightening during the connection process, allowing the pin hole protrusion to easily slide into the pin hole and automatically lock when it reaches the predetermined position, effectively preventing loosening caused by vibration or external force. At the same time, the presence of spring washers also allows the connection part to have a certain degree of self-adjustment ability when encountering slight deformation, thereby extending the service life of the entire component.
[0042] In addition, to meet the safety requirements under extreme working conditions, a safety locking mechanism is also added at the connection between the rear protection bracket and the belt protection cover. This mechanism is made of high-strength alloy material. After being activated manually or automatically, it can further strengthen the connection point to ensure that the connection will not fail even under extreme loads or impacts. The design of the safety lock is simple and efficient, and the operation is convenient, providing another solid barrier for the stable operation of the equipment.
[0043] In terms of appearance and detail processing, the entire connection system also demonstrates a high level of craftsmanship. The edges of the pin hole bumps and the pin holes are all finely polished to ensure smoothness during connection. At the same time, the insertion position of the split pin is also precisely calculated, which not only ensures its stability but also avoids an unnecessary obtrusive feeling on the appearance. The entire connection system is not only powerful in function but also neat and beautiful in appearance, fully reflecting the perfect combination of the designer's pursuit of practicality and aesthetics.
[0044] Both the fixed plate and the hook plate are designed in a plate shape. Among them, the hook plate is placed on one side of the fixed plate and is arranged at a perpendicular angle relative to the fixed plate. These two components are manufactured by an integral molding process, ensuring their structural integrity and fitting accuracy. On the surface of the fixed plate, several riveting holes II are designed. The main function of these holes is to provide connection points to achieve a tight fit with the belt protection cover. In addition, the connection between the fixed plate and the belt protection cover is achieved through riveting holes II and the corresponding riveting process for fixation. This fixation method is both firm and reliable, and can ensure a stable connection in various working environments.
[0045] In addition, the connection between the fixed plate and the belt protection cover is fixed by using blind rivets for riveting. This connection method has the advantages of simple structure, firm connection, and convenient disassembly. As a special type of rivet, the blind rivet is characterized in that during the riveting process, the core rod inside the rivet body will be pushed out, increasing the contact area between the rivet body and the connected parts, thereby improving the firmness of the connection. At the same time, the structure of the blind rivet also makes it more convenient to disassemble. Just gently tap the core rod to remove the rivet from the connected parts. Therefore, in this embodiment, using blind rivets to connect the fixed plate and the belt protection cover not only ensures the stability of the connection but also facilitates subsequent maintenance and replacement.
[0046] Specifically, the riveting holes II not only shoulder the heavy responsibility of structural fixation but also reserve sufficient operating space, enabling the riveting to be easily released with specific tools when the belt protection cover needs to be maintained or replaced, without damaging the entire structure. This design significantly reduces the maintenance cost and improves the work efficiency, and is a model of the combination of humanization and practicality in industrial equipment design.
[0047] Meanwhile, to enhance the durability and anti-fatigue performance of the entire structure, the material selection of the fixing plate and the hook plate has been carefully considered. They are usually made of high-strength and corrosion-resistant alloy materials, which can not only effectively resist wear and corrosion during daily use but also maintain the structural stability when subjected to large external forces, extending the service life of the equipment.
[0048] In addition, the vertical arrangement between the hook plate and the fixing plate not only optimizes the space utilization rate but also improves the installation flexibility. Whether it is horizontally installed or inclinedly installed, this design can ensure that the hook plate can firmly hold or support the belt protection cover, preventing it from shaking or falling off during operation, thus ensuring the operation safety and stability of the equipment.
[0049] The front protection bracket adopts a plate-shaped design, and a number of equally spaced through holes are evenly arranged on its surface to achieve good ventilation and heat dissipation effects. At the same time, one end of the front protection bracket extends outward and forms a bend, and a hook groove is provided at this bend. The design of the hook groove is ingenious and can closely cooperate with the hook plate. The size and shape of the hook plate perfectly fit the hook groove and can be stably accommodated in the hook groove, ensuring the firmness and reliability of the entire structure.
[0050] On the same side end of the front fixing hook plate and the rear protection bracket, an intermediate shaft mounting bracket is fixed. This bracket plays a connecting role, not only fixing the front fixing hook plate and the rear protection bracket but also undertaking the installation task of the intermediate shaft. The design of the intermediate shaft mounting bracket takes into account the installation convenience and structural stability. It is also specially provided with a central hole, which not only provides an accurate installation position for the intermediate shaft but also makes the entire structure more compact, saves space, and improves the overall performance of the equipment.
[0051] The beneficial effects produced by this embodiment are:
[0052] This embodiment includes a split pin and a front fixing hook plate. Through the split pin and the front fixing hook plate, the belt protection cover is cooperatively connected with the front protection bracket and the rear protection bracket. The split pin can effectively limit the longitudinal displacement of the belt protection cover, and the front fixing hook plate can effectively reduce the lateral displacement of the belt protection cover. The joint cooperation of the split pin and the front fixing hook plate makes the fixation of the belt protection cover more firm and stable. When the vehicle is driving on a bumpy road surface, the belt protection cover structure is still firmly fixed, reducing the problem of the belt protection cover falling off caused by bumps. Moreover, both the split pin and the front fixing hook plate are of quick-release design; by pulling out the split pin and offsetting and pulling out the front fixing hook plate and other operations, the belt protection cover can be disassembled without tools. Therefore, disassembly and maintenance are more convenient, facilitating the user's inspection of the vehicle condition in case of emergency, saving the disassembly and assembly time, improving the disassembly and assembly efficiency, eliminating any professional tools for disassembly and assembly, and can be operated by hand.
[0053] In addition to the above embodiments, within the scope disclosed in the claims and the specification of the present utility model, the technical features or technical data of the present utility model can be reselected and combined to form new embodiments, and these should also be regarded as specific embodiments of the present utility model and fall within the protection scope of the present utility model.
