Description

Technical Field

[0001] This utility model belongs to the field of windshield technology, and in particular relates to an installation structure for a curved windshield of a tractor. Background Technology

[0002] The installation structure of the tractor curved windshield is a special assembly system that adapts to the curved contour of the tractor cab and takes into account both sealing protection and shock resistance. It is usually based on the curved mounting frame of the metal frame at the front of the cab, such as cold-rolled steel or aluminum alloy. The inner side of the frame has a pre-set sealing groove and a weather-resistant rubber sealing strip. The glass body is made of reinforced curved glass, and the initial seal is achieved by the tight fit between the glass edge and the sealing strip.

[0003] However, existing windshields are fixed using bolts and nuts during installation. This requires aligning each bolt hole and tightening it during the installation phase. If maintenance or replacement is needed later, the bolts and nuts must be loosened and removed one by one. The whole process is cumbersome and time-consuming, which not only increases the workload of operators but also directly leads to a significant reduction in the efficiency of windshield installation and removal, making it difficult to meet the actual needs of efficient operation. Utility Model Content

[0004] The purpose of this utility model is to provide an installation structure for a curved windshield of a tractor. By setting a fixing part, the problem of using bolts and nuts for fixing is solved. This method requires aligning the bolt holes one by one and tightening them during the installation and fixing stage. If maintenance or replacement is required later, the bolts and nuts need to be loosened and removed one by one. The whole process is cumbersome and time-consuming. This not only increases the workload of the operators, but also directly leads to a significant reduction in the efficiency of windshield installation and removal, making it difficult to meet the actual needs of efficient operation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an installation structure for a curved windshield of a tractor, comprising a tractor and a curved mounting bracket mounted on the tractor. A plurality of mounting blocks are fixedly connected to the curved mounting bracket. The curved windshield is disposed on the front of each of the mounting blocks. Each of the mounting blocks has a fixing hole communicating with the curved windshield. The structure further includes: a fixing part, comprising a plurality of fixing parts disposed within the plurality of fixing holes; and a limiting part, comprising a plurality of limiting parts disposed on the fixing parts. The fixing part includes a quick-release mechanism. The quick-release assembly is disposed within a fixing hole; the fixing assembly is mounted on the quick-release assembly; the quick-release assembly includes a screw rod slidably connected within the fixing hole, the outer wall of the screw rod having a folding groove, two folding rods rotatably connected within the folding groove, two stops fixedly connected within the folding groove, a telescopic rod fixedly connected to the side of the two folding rods that are close to each other, a reset component provided on the outer wall of the telescopic rod, both stops being adapted to the two folding rods, the reset component including a spring wound around the outer wall of the telescopic rod, the ends of the springs that are far apart from each other being fixedly connected to the two folding rods.

[0007] Furthermore, the limiting part includes a balancing component mounted on the mounting block; and a limiting component mounted on the balancing component.

[0008] Furthermore, the fixing component includes several positioning holes on the back of the mounting block, a limiting groove on the screw, a limiting ring slidably connected in the limiting groove, a nut threadedly connected to the outer wall of the screw, and the front end of the limiting ring extending into the several positioning holes and slidably connected to them. The several positioning holes on the back of the mounting block can provide multiple fixing points for the screw to adapt to different position adjustment needs. The limiting groove on the screw provides a sliding guide for the limiting ring, ensuring that the limiting ring is accurately inserted into the corresponding positioning hole and initially locking the position of the screw. The nut threadedly connected to the outer wall can further tighten the limiting ring, enhance the locking stability, and prevent the limiting ring from loosening and dislodging from the positioning hole.

[0009] Furthermore, the balancing assembly includes a rectangular plate fixedly connected to the back of the mounting block. Two balance rods are slidably connected to the rectangular plate. Limiting blocks are fixedly connected to the left ends of the two balance rods. The limiting blocks are adapted to nuts. The rectangular plate on the back of the mounting block provides stable sliding support for the two balance rods, ensuring that the balance rods do not deviate when moving. The limiting blocks at the left ends of the balance rods are adapted to nuts. The limiting blocks can be tightened to lock the nuts by sliding the balance rods, preventing the nuts from loosening due to vibration during equipment operation, and further reinforcing the fixed state of the screw.

[0010] Furthermore, the limiting component includes a screw threadedly connected to a rectangular plate. The left end of the screw is rotatably connected to a limiting block. A rotating component is provided on the screw, including a knob sleeved on the outer wall of the screw. The knob is located on the outer wall of the right end of the screw. The left end of the screw threadedly connected to the rectangular plate is rotatably connected to the limiting block. By rotating the knob at the right end, the screw can be driven to rotate. The threaded transmission drives the limiting block to move precisely, ensuring that it is tightly engaged or disengaged from the nut.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting a fixing part, when installing the curved windshield to the tractor, first align the fixing holes on the glass with the fixing holes on the mounting block of the curved mounting bracket, then insert the screw into the fixing hole. The folding rod at its front end is squeezed and folds inward and retracts into the folding groove. At the same time, the compression telescopic rod and spring accumulate potential energy. After the screw is fully inserted, the folding rod unfolds under the reset thrust. Pull the screw to make the folding rod fit against the glass and limit its position. The stop block limits the angle of the folding rod. Then, insert the limiting ring into the limiting groove at the other end of the screw, which matches the positioning hole of the mounting block to prevent the screw from rotating. Finally, screw in the nut to fix it. This setting eliminates the cumbersome steps of traditional installation, simplifies the process, improves efficiency, and ensures that the structure is initially stable after installation.

[0013] 2. By setting a limiting part, after the nut on the screw is fixed in place, turn the knob on the screw so that the knob drives the screw to slowly rotate under the assistance of the rectangular plate and the guidance of the two balance bars. This pushes the limiting block closer to the nut and limits the nut. This setting can effectively prevent the nut from loosening or falling off due to vibration when the tractor is operating, further strengthen the installation structure of the curved windshield, and ensure its long-term stability and safety.

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.

[0024] Please see Figure 1-5As shown, this utility model is an installation structure for a curved windshield of a tractor, including a tractor 111 and a curved mounting bracket 112 mounted on the tractor 111. A plurality of mounting blocks 113 are fixedly connected to the curved mounting bracket 112. A curved windshield 114 is provided on the front of each mounting block 113. Each mounting block 113 has a fixing hole 115, which communicates with the curved windshield 114. The structure also includes: a fixing part 2, of which a plurality of fixing parts 2 are provided, each disposed within one of the fixing holes 115; and a limiting part 3. Several limiting parts 3 are provided, and all of the limiting parts 3 are provided on the fixing part 2; the fixing part 2 includes a quick-release assembly 21, which is disposed in the fixing hole 115; a fixing assembly 22 is mounted on the quick-release assembly 21; the quick-release assembly 21 includes a screw 211 slidably connected in the fixing hole 115, a folding groove 212 is provided on the outer wall of the screw 211, two folding rods 213 are rotatably connected in the folding groove 212, two stops 214 are fixedly connected in the folding groove 212, and a telescopic rod 2 is fixedly connected to one side of the two folding rods 213 that are close to each other. 15. The outer wall of the telescopic rod 215 is provided with a reset component. Both stops 214 are adapted to the two folding rods 213. The fixing component 22 includes several positioning holes 221 opened on the back of the mounting block 113. A limit groove 222 is opened on the screw 211. A limit ring 223 is slidably connected in the limit groove 222. A nut 224 is threadedly connected to the outer wall of the screw 211. The front end of the limit ring 223 extends into several positioning holes 221 and is slidably connected to several positioning holes 221. The reset component includes a spring 216 wound around the outer wall of the telescopic rod 215. The spring 216 is... The ends that are far apart from each other are fixedly connected to two folding rods 213. By setting the fixing part 2, the following steps can be taken during the installation of the curved windshield 114 and the tractor 111: First, the fixing holes 115 on the curved windshield 114 need to be aligned and matched with the fixing holes 115 of the multiple mounting blocks 113 on the curved mounting bracket 112. After the alignment is completed, one end of the screw 211 is inserted into the fixing hole 115. During the insertion process, the two folding rods 213 at the front end of the screw 211 will be squeezed by the fixing hole 115, and then fold inward and retract into the folding groove 212.During retraction, the telescopic rod 215 and spring 216 in the folding groove are simultaneously compressed, allowing the spring to accumulate elastic potential energy and providing power support for the subsequent reset of the folding rod. When the screw 211 completely passes through the fixing hole 115, the two folding rods 213 in the folding groove 212 will unfold under the reset thrust of the telescopic rod 215 and spring 216. At this time, pull the screw 211 to the other end, causing it to drive the two unfolded folding rods 213 to completely fit against the curved windshield 114, and limit the insertion end of the screw 211. At the same time, the two stops 214 in the folding groove 212 will limit the angle of the unfolded folding rods 213 to prevent them from over-extending. To facilitate subsequent operations, the limiting ring 223 is inserted into the limiting groove 222 at the other end of the screw 211, and the limiting ring 223 is fitted with the multiple positioning holes 221 on the mounting block 113. This design positions the screw 211, effectively preventing it from rotating during subsequent operations. After the screw 211 is positioned, the nut 224 is screwed into the screw 211 to fix the other end of the screw 211. This design eliminates the tedious steps of aligning the holes one by one and making repeated adjustments in traditional installation, greatly simplifying the installation process of the curved windshield, improving installation efficiency, and ensuring the initial stability of the structure after installation.

[0025] The limiting part 3 includes a balancing component 31, which is mounted on the mounting block 113; and a limiting component 32, which is mounted on the balancing component 31. The balancing component 31 includes a rectangular plate 311 fixedly connected to the back of the mounting block 113. Two balancing rods 312 are slidably connected to the rectangular plate 311. A limiting block 313 is fixedly connected to the left end of the two balancing rods 312. The limiting block 313 is adapted to a nut 224. The limiting component 32 includes a screw 321 threadedly connected to the rectangular plate 311. The left end of the screw 321 is rotatably connected to the limiting block 313. A rotating component is provided on the screw 321, which includes components sleeved on the outside of the screw 321. The knob 322 is located on the outer wall of the right end of the screw 321. By setting the limiting part 3, after the nut 224 on the screw 211 is fixed in place, the knob 322 on the screw 321 is rotated. The knob 322 drives the screw 321 to slowly rotate under the assistance of the rectangular plate 311 and the guidance of the two balance bars 312. This pushes the limiting block 313 closer to the nut 224, and finally limits the nut 224. This setting can effectively prevent the nut 224 from loosening or falling off due to vibration during tractor operation, further strengthen the installation structure of the curved windshield, and ensure its long-term stability and safety.

[0026] A specific application of this embodiment is as follows: During the installation of the curved windshield 114 and the tractor 111, the following steps can be followed: First, the fixing holes 115 on the curved windshield 114 need to be aligned with the fixing holes 115 of the multiple mounting blocks 113 on the curved mounting bracket 112. After alignment, one end of the screw 211 is inserted into the fixing hole 115. During insertion, the two folding rods 213 at the front end of the screw 211 will be squeezed by the fixing hole 115, and then fold inward and retract into the folding groove 212; when retracting, the telescopic rods 215 in the groove will also be compressed simultaneously. Spring 216 stores elastic potential energy to provide power support for the subsequent reset of the folding rods. After screw 211 completely passes through the fixing hole 115, the two folding rods 213 in the folding groove 212 will unfold under the reset thrust of the telescopic rod 215 and spring 216. At this time, pull screw 211 to the other end to make the unfolded two folding rods 213 completely fit against the curved windshield 114 and limit the insertion end of screw 211. At the same time, the two stops 214 in the folding groove 212 will limit the angle of the unfolded folding rods 213 to prevent them from over-unfolding and affecting the windshield. In the next step, the limiting ring 223 is inserted into the limiting groove 222 at the other end of the screw 211, and the limiting ring 223 is fitted with the multiple positioning holes 221 on the mounting block 113. This design positions the screw 211, effectively preventing it from rotating during subsequent operations. After the screw 211 is positioned, the nut 224 is screwed into the screw 211 to fix the other end of the screw 211. This setting eliminates the tedious steps of aligning the holes one by one and making repeated adjustments in traditional installation, greatly simplifying the installation process of the curved windshield and improving installation efficiency. Ensure the initial stability of the structure after installation; after the nut 224 on the screw 211 is fixed in place, rotate the knob 322 on the screw 321. With the assistance of the rectangular plate 311 and the guidance of the two balance bars 312, the screw 321 slowly rotates in, thereby pushing the limit block 313 closer to the nut 224, and finally limiting the nut 224. This setting can effectively prevent the nut 224 from loosening or falling off due to vibration during tractor operation, further strengthening the installation structure of the curved windshield and ensuring its long-term stability and safety.
