Description

Technical Field

[0001] This utility model relates to the field of chain box technology, specifically a plastic chain box for vehicles. Background Technology

[0002] A motorcycle chain guard (also known as a chain protector) is a device used to protect the chain in a motorcycle's drivetrain. Its function is to prevent the chain from colliding with external objects, reduce chain wear, extend chain life, and prevent the chain from slipping or jumping.

[0003] For example, the motorcycle chain box installation structure disclosed in patent publication number CN219134378U includes an upper chain box and a lower chain box. The upper chain box has a positioning post at its lower end, and the lower chain box has a positioning hole at its upper end. Upper fixing plates are symmetrically arranged on both sides of the upper chain box, and lower fixing plates are symmetrically arranged on both sides of the lower chain box. A pressing assembly is provided on the upper fixing plate, including a lifting rod that reciprocates linearly in a vertical direction. A rotatable locking block is provided at the bottom of the lifting rod, and an oil injection hole is provided at the end of the upper chain box. This installation structure allows the upper and lower chain boxes to be installed relatively quickly together through the lifting rod and locking block, protecting the chain from dirt entry. Furthermore, the lower chain box is detachable for easy maintenance, solving the problem of the entire chain box being difficult to disassemble and assemble. While the above device solves the problem of the entire chain box being difficult to disassemble and assemble, it still has certain shortcomings.

[0004] A typical chain box consists of two U-shaped boxes, one upper and one lower, fixed around the chain. When a motorcycle is in motion, especially on muddy roads, the chain accumulates a lot of dust during high-speed transmission. Oil, dust, and other grime build up on the inner wall of the chain box, requiring maintenance personnel to remove and clean it to ensure unimpeded chain operation and reduce wear. However, cleaning a U-shaped chain box is difficult and inconvenient.

[0005] Therefore, existing chain boxes suffer from the drawback of being difficult to clean. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a plastic chain box for vehicles, making the chain box easier to clean.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a vehicle plastic chain box, comprising two half-boxes forming the chain box body, each half-box being composed of a left plate and a right plate, a connecting plate being fixedly connected to the inner side wall of the left plate, and a side plate being fixedly connected to the inner side wall of the right plate, the connecting plate being located at the top of the side plate and being snapped into it, and screws being threaded to both ends of the connecting plate and the side plate.

[0008] Furthermore, a fixing plate is fixedly connected to the outer wall of the connecting plate, and multiple insert plates are fixedly connected to the inner side of the fixing plate. Slots are provided on the connecting plate and the side plate, and the insert plates are inserted into the slots.

[0009] Furthermore, an elastic protrusion is fixedly connected to the bottom of the insert plate, and the bottom of the elastic protrusion is rounded.

[0010] Furthermore, protruding plates are fixedly connected to the inner walls of both ends of the connecting plate, and grooves are provided on the inner walls of the protruding plates, which are inserted into the two ends of the side plates.

[0011] Furthermore, the screws penetrate the fixing plate, connecting plate, and side plate for threaded connection.

[0012] Furthermore, the slot is designed as a rectangular slot.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention separates the original one-piece half-box into a left and right panel, allowing for easy separation during cleaning. This facilitates cleaning of both panels and, compared to the original U-shaped half-box, makes it much easier for maintenance personnel to thoroughly clean the oil and dust accumulated on the inner walls of the left and right panels without any limitations. The use of connecting plates and side plates, along with screws, makes it easy to connect and secure the left and right panels after connection. The structure is simple, easy to operate, and highly practical. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figures 1 to 7 As shown, a vehicle plastic chain box includes two half-boxes forming the chain box body 1. Each half-box is composed of a left plate 11 and a right plate 12. A connecting plate 7 is fixedly connected to the inner side wall of the left plate 11, and a side plate 6 is fixedly connected to the inner side wall of the right plate 12. The connecting plate 7 is located on the top of the side plate 6 and is snapped into it. Both ends of the connecting plate 7 and the side plate 6 are threaded with screws 3.

[0025] like Figure 1 As shown, the automotive plastic chain box of this utility model has a similar installation structure to the existing motorcycle chain box, such as the motorcycle chain box installation structure disclosed in patent publication number CN219134378U. The main improvement of this utility model is that it makes the chain box easier to clean. Figures 1 to 7 As shown, when the vehicle plastic chain box of this utility model needs to be cleaned after a period of use, the chain box body 1 can be removed from the motorcycle frame. Then, the left plate 11 and the right plate 12 of one half of the box can be separated. During separation, it is only necessary to separate the screws 3 at both ends of the side plate 6 and the connecting plate 7, so that the side plate 6 and the connecting plate 7 are no longer restricted. Then, the connecting plate 7 on the left plate 11 can be separated from the side plate 6 on the right plate 12. After separation, the left plate 11 and the right plate 12 become two plates, making cleaning simpler and more convenient.

[0026] By dividing the original one-piece half-box into a left panel 11 and a right panel 12, the two can be directly separated during cleaning, making it easier for people to clean the left panel 11 and the right panel 12. Compared with the original U-shaped half-box, it is easier for maintenance personnel to thoroughly clean the oil stains and dust accumulated on the inner walls of the left panel 11 and the right panel 12 without any restrictions. By using the connecting plate 7 and the side plate 6 in conjunction with the screws 3, the left panel 11 and the right panel 12 are easy to connect and fix after being connected.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, a fixing plate 2 is fixedly connected to the outer wall of the connecting plate 7, and multiple insert plates 5 are fixedly connected to the inner side of the fixing plate 2. Slots 4 are provided on the connecting plate 7 and the side plate 6, and the insert plates 5 are inserted into the slots 4.

[0028] Specifically, before using screw 3 to fix it, the user can first place the fixing piece 2 on the top surface of the connecting plate 7, so that the insert plate 5 is just engaged with the slot 4. This setting can ensure that the left plate 11 and the right plate 12 are more stable, and ensure the stable connection between the left plate 11 and the right plate 12 during long-term use and chain operation, preventing them from loosening.

[0029] like Figure 5 As shown, a flexible protrusion 51 is fixedly connected to the bottom of the insert plate 5, and the bottom of the flexible protrusion 51 is arc-shaped. By setting the bottom of the insert plate 5 as a flexible protrusion 51, when the insert plate 5 is connected to the slot 4, the flexible protrusion 51 at the bottom of the insert plate 5 will directly lock into the bottom of the slot 4. This setting fixes the insert plate 5 in the slot 4, further reinforcing the fixing piece 2; at the same time, the arc-shaped bottom of the flexible protrusion 51 makes it easier to insert into the slot 4.

[0030] like Figure 6 and Figure 7 As shown, protruding plates 71 are fixedly connected to the inner walls of both ends of the connecting plate 7. The inner walls of the protruding plates 71 are provided with grooves, which are inserted into the two ends of the side plate 6.

[0031] Specifically, when the side plate 6 and the connecting plate 7 are engaged, the protruding plate 71 ensures that the side plate 6 and the connecting plate 7 have a certain degree of stability after being inserted.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, screw 3 passes through the fixing plate 2, the connecting plate 7, and the side plate 6, forming a threaded connection. This arrangement allows the fixing plate 2, the connecting plate 7, and the side plate 6 to form a relatively tight whole, resulting in stronger connectivity and increased stability.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, slot 4 is a rectangular slot. This design allows the insert plate 5 to be confined within slot 4, further stabilizing the fixing piece 2 on the outside of the connecting plate 7.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
