Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a shovel. Background Technology

[0002] Currently, due to the impact of the economic downturn and declining demand in the automotive market, competition in the automotive industry is becoming increasingly fierce. Faced with declining market demand, automakers are resorting to measures such as lowering prices to increase sales and capture market share. To implement the concept of producing the highest quality cars at the lowest cost and eliminate waste in the production process, an investigation of the vehicle production process revealed that after the PVC (Polyvinyl chloride) was used up, a large amount of unused PVC adhesive remained on the inner wall of the tank. Even using a stainless steel shovel, it was impossible to scrape off most of the PVC adhesive adhering to the inner wall of the tank, resulting in material waste and increased production costs.

[0003] Therefore, how to scrape off the residual adhesive adhering to the inner wall of the can is a problem that urgently needs to be solved. Utility Model Content

The handle includes a telescopic rod, and the shovel head includes a polyurethane shovel head. The connecting mechanism includes a joint assembly and an adjusting assembly. The adjusting assembly includes a connecting frame and a fastener. The telescopic rod and the connecting frame are both connected to the joint assembly. The connecting frame is provided with a mutually communicating limiting groove and a threaded hole. The fastener is provided with a threaded section. The limiting groove is used to accommodate at least a portion of the structure of the polyurethane shovel head. The threaded section is threadedly engaged with the threaded hole. The fastener is used to abut against the polyurethane shovel head located in the limiting groove, so that the fastener can restrict the movement of the polyurethane shovel head relative to the connecting frame.

[0006] In one embodiment, the fastener includes an abutment portion, a connecting portion, and an operating portion. The abutment portion and the operating portion are respectively connected to both ends of the connecting portion. The outer wall of the connecting portion is provided with the threaded section. The diameter of the abutment portion is larger than the diameter of the connecting portion. The abutment portion is used to abut against the polyurethane shovel head located in the limiting groove.

[0007] In one embodiment, the opening of the limiting groove is disposed away from the connector assembly.

[0008] In one embodiment, the connector assembly includes a direct head, a first reinforcing connector, and a second reinforcing connector. The two ends of the direct head are respectively connected to the telescopic rod and the connecting frame. The first reinforcing connector and the second reinforcing connector are respectively located on both sides of the direct head. The two ends of the first reinforcing connector are respectively connected to the telescopic rod and the connecting frame, and the two ends of the second reinforcing connector are respectively connected to the telescopic rod and the connecting frame.

[0009] In one embodiment, the included angle between the first reinforcing joint and the direct head ranges from 30° to 55°;

[0010] And / or,

[0011] The angle between the second reinforcing connector and the direct connector ranges from 30° to 55°.

[0012] In one embodiment, the connecting frame includes a first frame body, a second frame body, and a third frame body. The first frame body, the second frame body, and the third frame body are spaced apart along the width direction of the polyurethane shovel head. Each of the first frame body, the second frame body, and the third frame body is provided with mutually communicating limiting grooves and threaded holes. The number of fasteners is the same as the number of threaded holes and they are arranged in a one-to-one correspondence. The first frame body is connected to the first reinforcing joint, the second frame body is connected to the direct head, and the third frame body is connected to the second reinforcing joint.

[0013] In one embodiment, the telescopic rod includes a telescopic region and a gripping region, the telescopic region and the gripping region being slidably engaged, and one end of the telescopic region away from the gripping region being connected to the connector assembly.

[0014] In one embodiment, the shovel further includes an anti-slip rubber pad disposed in the gripping area.

[0015] In one embodiment, the polyurethane shovel head includes a support portion and a working portion, a limiting groove for accommodating at least a portion of the structure of the support portion, and a fastener for abutting against the support portion located within the limiting groove, such that the fastener can restrict the movement of the support portion relative to the connecting frame; the side of the support portion away from the connecting frame is connected to the working portion, and the size of the working portion is smaller than the size of the support portion.

[0016] In one embodiment, the size of the working part is gradually reduced along a first direction.

[0017] In this embodiment of the invention, the telescopic rod design allows the shovel to adapt to plastic cans of different heights. The length before extension is 1.5 meters, and the length after extension can reach 2.7 meters. This design minimizes the space occupied when not in use, making it easy to store, while easily handling plastic cans of various heights. The traditional stainless steel shovel head is replaced with a polyurethane shovel head. The elastic properties of polyurethane allow the shovel head to better conform to the curved inner wall of the plastic can, thus scraping away the adhering substances more efficiently and thoroughly, effectively improving cleaning efficiency and quality. The polyurethane shovel head is simple and quick to assemble and disassemble; different sizes of polyurethane shovel heads can be easily replaced by loosening or tightening the fasteners to adapt to plastic cans of different sizes and opening diameters. This design greatly improves the flexibility and practicality of the shovel. Compared to traditional stainless steel shovels, the weight of the shovel in this invention is significantly reduced from 8 kg to 3 kg, making it easier for the operator during use and effectively reducing the operator's labor intensity. This utility model embodiment uses a telescopic rod to adjust the length of the shovel handle, allowing the shovel to adapt to glue cans of different depths, providing greater flexibility and applicability. The polyurethane shovel head better conforms to the inner walls of cans with various curvatures, enabling more efficient and thorough scraping of residual glue, improving cleaning efficiency and effectiveness. The design of the connector and adjustment components allows for quick adjustment of the polyurethane shovel head's position and fastening status, enabling the shovel to be quickly configured according to different cleaning needs. The design of the limiting groove and threaded hole, along with its engagement with the threaded section on the fastener, allows for precise fixation of the polyurethane shovel head, ensuring its stability and reliability during cleaning.

[0032] Currently, due to the economic downturn and declining demand in the automotive market, competition in the automotive industry is becoming increasingly fierce. Faced with declining market demand, automakers are resorting to measures such as lowering prices to increase sales and capture market share. To implement the concept of producing the highest quality cars at the lowest cost and eliminate waste in the production process, an investigation revealed that after the PVC receiving tank was used up, a large amount of unused PVC glue remained on the inner wall of the tank. Even using a stainless steel shovel, it was impossible to scrape off most of the PVC glue adhering to the inner wall of the tank, resulting in material waste and increased production costs.

[0033] After careful investigation, the applicant discovered that due to the strong adhesion of PVC glue, a significant portion of it remains on the glue can after use. Furthermore, because the glue cans are cylindrical with a curved inner wall, existing stainless steel spatulas not only cannot fully adhere to the can's inner wall but are also too heavy due to their material, making it difficult to scrape off most of the PVC glue, resulting in material waste and increased production costs. Moreover, existing spatulas are inconvenient to use with shorter glue cans due to their short extension rods; and with cans having smaller openings, the spatulas are too large, requiring the use of smaller-headed spatulas. Additionally, due to the varying sizes and curvatures of glue cans, even with multiple spatulas of different lengths and head curvatures, the removal of residual glue from the inner wall remains unsatisfactory.

[0034] The main purpose of this invention is to propose a scraper to solve the problem of how to scrape off the residual adhesive adhering to the inner wall of a can.

[0035] Please see Figures 1 to 4In one embodiment of this utility model, the shovel 100 includes a shovel handle 1, a connecting structure 2, and a shovel head. The shovel handle 1 includes a telescopic rod 11, and the shovel head includes a polyurethane shovel head 3. The connecting mechanism includes a connector assembly 21 and an adjusting assembly 22. The adjusting assembly 22 includes a connecting frame 221 and a fastener 222. The telescopic rod 11 and the connecting frame 221 are both connected to the connector assembly 21. The connecting frame 221 is provided with a limiting groove 22111 and a threaded hole (not shown in the figure) that are interconnected. The fastener 222 is provided with a threaded section 22221. The limiting groove 22111 is used to accommodate at least a part of the structure of the polyurethane shovel head 3. The threaded section 22221 is threadedly engaged with the threaded hole. The fastener 222 is used to abut against the polyurethane shovel head 3 located in the limiting groove 22111, so that the fastener 222 can restrict the movement of the polyurethane shovel head 3 relative to the connecting frame 221.

[0036] In this embodiment of the invention, the telescopic rod 11 allows the shovel 100 to adapt to plastic cans of different heights. Its length before extension is 1.5 meters, and after extension it can reach 2.7 meters. This design makes the shovel 100 space-saving when not in use, facilitating storage, while easily handling plastic cans of various heights. The traditional stainless steel shovel head is replaced with a polyurethane shovel head 3. The elastic properties of polyurethane allow the shovel head to better conform to the curved inner wall of the plastic can, thus scraping away the adhering substances more efficiently and thoroughly, effectively improving cleaning efficiency and quality. The polyurethane shovel head 3 is easy to assemble and disassemble; different sizes of polyurethane shovel heads 3 can be easily replaced by loosening the fasteners 222 to adapt to plastic cans of different sizes and opening diameters. This design greatly improves the flexibility and practicality of the shovel 100. Compared to traditional stainless steel shovels, the weight of the shovel 100 of this invention is significantly reduced from 8 kg to 3 kg, making it easier for the operator during use and effectively reducing the operator's labor intensity.

[0037] The technical solution of this utility model uses a telescopic rod 11 to adjust the length of the shovel handle 1, enabling the shovel 100 to adapt to glue cans of different depths, providing greater flexibility and applicability. The use of a polyurethane shovel head 3 allows for better contact with the inner walls of cans with various curvatures, enabling more efficient and thorough scraping of residual adhesive from the inner walls, thus improving cleaning efficiency and effectiveness. The design of the connector assembly 21 and the adjustment assembly 22 allows for quick adjustment of the position and fastening state of the polyurethane shovel head 3, allowing the shovel 100 to be quickly configured according to different cleaning needs. The design of the limiting groove 22111 and the threaded hole, along with the engagement with the threaded section 22221 on the fastener 222, allows for precise fixing of the polyurethane shovel head 3, ensuring its stability and reliability during cleaning.

[0038] In this embodiment, polyurethane boards can be cut into different models of polyurethane shovel heads 3 according to different sizes and thicknesses to cope with glue cans of different sizes and curvatures. This not only increases the variety of polyurethane shovel head 3 models, but also effectively reduces production costs.

[0039] Please see Figures 4 to 6 In one embodiment, the fastener 222 includes an abutment portion 2221, a connecting portion 2222, and an operating portion 2223. The abutment portion 2221 and the operating portion 2223 are respectively connected to both ends of the connecting portion 2222. A threaded section 22221 is provided on the outer wall of the connecting portion 2222. The diameter of the abutment portion 2221 is larger than the diameter of the connecting portion 2222. The abutment portion 2221 is used to abut against the polyurethane shovel head 3 located in the limiting groove 22111. Specifically, the threaded section 22221 is provided on the outer wall of the operating portion 2223, allowing the user to adjust the tightness of the fastener 222 by rotating the operating portion 2223. Precise control of the fixed state between the polyurethane scraper head 3 and the connecting frame 221 ensures the stability and reliability of the polyurethane scraper head 3 under various working conditions. It is also easy to operate, as the fastener 222 can be tightened or loosened with a simple rotation action, making the installation and replacement of the polyurethane scraper head 3 faster and more convenient, and also easier for subsequent maintenance. The diameter of the abutment part 2221 of the fastener 222 is larger than the diameter of the connecting part 2222. This design increases the contact area between the fastener 222 and the polyurethane scraper head 3, improves the stability of the connection, and ensures that the scraper head will not loosen or fall off due to force during the scraping process.

[0040] In one embodiment, the opening of the limiting groove 22111 is positioned opposite to the joint assembly 21. Specifically, the positioning groove 22111's opening being positioned opposite to the joint assembly 21 helps maintain the straight alignment between the polyurethane shovel head 3 and the shovel handle 1. This allows the operator to move the shovel 100 downwards more smoothly, reducing force loss and improving work efficiency. It also makes it easier for the operator to scrape the residual adhesive on the inner wall of the tank with the shovel 100, allowing them to feel the force acting on the polyurethane shovel head 3 more directly. The operator can better control the force and direction, ensuring the cleaning effect.

[0041] In one embodiment, the connector assembly 21 includes a direct head 211, a first reinforcing connector 212, and a second reinforcing connector 213. The two ends of the direct head 211 are respectively connected to the telescopic rod 11 and the connecting frame 221. The first reinforcing connector 212 and the second reinforcing connector 213 are located on opposite sides of the direct head 211. The two ends of the first reinforcing connector 212 are respectively connected to the telescopic rod 11 and the connecting frame 221, and the two ends of the second reinforcing connector 213 are respectively connected to the telescopic rod 11 and the connecting frame 221. Specifically, by providing the first reinforcing connector 212 and the second reinforcing connector 213, the mechanical strength of the entire shovel 100 can be enhanced, making the shovel 100... The first reinforcing joint 212 and the second reinforcing joint 213 can effectively distribute the force acting on the direct head 211 during the use of the scraper 100, reduce stress concentration, thereby reducing the risk of the scraper 100 breaking or being damaged, reducing the replacement frequency, reducing maintenance costs, and improving the durability and stability of the scraper 100. In addition, the first reinforcing joint 212 and the second reinforcing joint 213 are located on both sides of the direct head 211, and this symmetrical layout provides more balanced support and improves the connection stability between the telescopic rod 11 and the connecting frame 221.

[0042] In one embodiment, the included angle between the first reinforcing joint 212 and the direct head 211 ranges from 30° to 55°; and / or, the included angle between the second reinforcing joint 213 and the direct head 211 ranges from 30° to 55°. Specifically, the included angles between the first reinforcing joint 212 and the direct head 211, and between the second reinforcing joint 213 and the direct head 211, allow the joint assembly 21 to distribute the force more evenly when bearing load, reducing local stress concentration and thus lowering the risk of breakage of the shovel 100. Furthermore, by providing the clamps, the force-bearing area of ​​the polyurethane shovel head 3 in the width direction can be increased, thereby increasing the stability of the polyurethane shovel head 3. In this embodiment, the included angle between the first reinforcing joint 212 and the direct head 211 is 45°, and the included angle between the second reinforcing joint 213 and the direct head 211 is 45°.

[0043] In one embodiment, the connecting frame 221 includes a first frame body 2211, a second frame body 2212, and a third frame body 2213. The first frame body 2211, the second frame body 2212, and the third frame body 2213 are spaced apart along the width direction of the polyurethane shovel head 3. Each of the first frame body 2211, the second frame body 2212, and the third frame body 2213 is provided with interconnected limiting grooves 22111 and threaded holes. The number of fasteners 222 is the same as the number of threaded holes and they are arranged in a one-to-one correspondence. The first frame body 2211 is connected to the first reinforcing joint 212, and the second frame body 2212 is connected to the direct head 211. Next, the third body 2213 is connected to the second reinforcing joint 213. Specifically, by arranging the first body 2211, the second body 2212, and the third body 2213 at intervals along the width direction of the polyurethane shovel head 3, the force acting on the polyurethane shovel head 3 can be distributed more evenly, reducing stress concentration. By arranging the first body 2211, the second body 2212, and the third body 2213, three support points are provided for the polyurethane shovel head 3, thereby enhancing the structural strength and stability of the entire shovel 100 and reducing the safety risks that may occur due to unstable connections during long-term repeated use.

[0044] In one embodiment, the telescopic rod 11 includes a telescopic region 111 and a gripping region 112, which are slidably engaged. One end of the telescopic region 111 away from the gripping region 112 is connected to the connector assembly 21. Specifically, the slidable engagement between the telescopic region 111 and the gripping region 112 means that the user can easily adjust the length of the shovel 100 as needed, providing greater flexibility to adapt to different working environments and heights without additional tools or complex operations, reducing adjustment time and improving work efficiency. In this embodiment, the telescopic rod 11 is also provided with a button 113 and a limiting member. The button 113 can control the extension and retraction of the telescopic rod 11. The button 113 is connected to the end of the gripping area 112 away from the telescopic area 111. The limiting member is connected to the gripping area 112 and slides with the telescopic area 111. The button 113 is connected to the limiting member in a transmission manner. The button 113 can drive the limiting member to slide relative to the telescopic area 111. When the telescopic rod 11 is extended, the button 113 is pressed. The button 113 drives the limiting member to slide relative to the telescopic area 111 so that the limiting member and the telescopic area 111 are separated, thereby allowing the telescopic area 111 to automatically extend and lock. The telescopic rod 11 can be extended for use with glue cans of different depths. After the work is completed, the button 113 is pressed. The button 113 drives the limiting member to return to its original position. Both hands are pressed inward to retract the telescopic area 111 relative to the gripping area 112 until the limiting member and the telescopic area 111 abut against each other, and the telescopic rod 11 is fully retracted.

[0045] According to one embodiment of the present invention, the telescopic rod 11 includes an electric telescopic rod, which can be extended or retracted by a button 113 or a remote control. It requires no effort and is convenient and quick to operate. Moreover, the electric telescopic rod, through automated control and precise positioning, can reduce the time and difficulty of manual operation and improve work efficiency.

[0046] In one embodiment, the shovel 100 also includes an anti-slip rubber pad 4, which is disposed in the grip area 112. Specifically, by providing the anti-slip rubber pad 4, the operator's grip experience can be optimized, and the comfort of using the shovel 100 can be improved. When the user operates the shovel 100 by holding it with both hands on the anti-slip rubber pad 4 in the grip area 112, the anti-slip rubber pad 4 provides additional friction, which can prevent the hands from slipping, allowing the operator to better grip the handle 1, reducing the risk of slipping, and improving the safety and durability of use.

[0047] Please see Figure 7 In one embodiment, the polyurethane shovel head 3 includes a support portion 31 and a working portion 32. A limiting groove 22111 is used to accommodate at least a portion of the structure of the support portion 31. A fastener 222 is used to abut against the support portion 31 located within the limiting groove 22111, so that the fastener 222 can restrict the movement of the support portion 31 relative to the connecting frame 221. The side of the support portion 31 away from the connecting frame 221 is connected to the working portion 32, and the size of the working portion 32 is smaller than the size of the support portion 31. Specifically, the support portion 31 is connected to the fastener via the limiting groove 22111. 222 is fixed to the connecting frame 221, providing better structural stability for the working part 32 and ensuring that the polyurethane shovel head 3 will not shift or fall off during use; the working part 32 can be ground thinner, and the size of the working part 32 is smaller than that of the support part 31, making the working part 32 more prone to elastic deformation, thereby being able to cope with more inner walls of different curvatures, increasing the applicability and flexibility of the shovel 100, and the working part 32 can penetrate deeper into the corners and gaps of the inner wall of the tank during scraping, improving the effect and thoroughness of scraping residual adhesive.

[0048] In one embodiment, the size of the working part 32 is gradually reduced along a first direction; specifically, the first direction is the vertical direction. The size of the working part 32 is gradually reduced along the vertical direction, which makes the working part 32 more easily deformable, helps to concentrate the force on the tip of the working part 32, and makes it easier for the polyurethane shovel head 3 to be inserted into narrow or hard-to-reach areas, improving cleaning efficiency. It also allows the operator to more accurately control the position and direction of the shovel head, especially when performing delicate work. Moreover, the gradually reduced design provides a streamlined appearance, increasing the aesthetics of the shovel 100.

[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
