A structure for quickly installing blades on blade forks

Abstract

The utility model discloses a structure for quickly assembling a blade on a blade fork. During the factory assembly process of the utility model, the plug-in rod and the blocking member are fixedly installed on the blade fork to form an integral structure. Therefore, during the on-site assembly process of the utility model, it is only necessary to assemble the blade on the blade fork. During the on-site assembly, the staff operates the blade to align the plug-in hole with the corresponding end of the plug-in rod, and then operates the blade to move toward the side of the blade fork so that the blocking member passes through the plug-in hole and is fully or partially exposed outside the plug-in hole, that is, the plug-in hole is sleeved on the plug-in rod and is located between the blocking member and the blade fork. At this moment, the blocking member elastically deforms and resets to act on the upper surface of the blade, providing the blade with a force that tends to move in the direction of the blade fork, so that the blocking member cooperates with the blade fork to clamp and lock the blade. For this reason, the utility model has the characteristics of convenient assembly and stable and reliable connection.

[0028] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-5As shown, the utility model is a structure for quickly installing a blade 2 on a blade fork 1, comprising a blade fork 1 and a blade 2, wherein a quick-installation structure 3 for quickly assembling the blade 2 on the blade fork 1 is provided between the blade 2 and the blade fork 1, the quick-installation structure 3 comprises a plug-in hole 31 provided on the blade 2 and a plug-in rod 32 provided on the blade fork 1 and used for the plug-in hole 31 to be sleeved, the plug-in rod 32 is provided with a blocking member 33 which is elastically deformable and has a cross-sectional width greater than the inner diameter of the plug-in hole 31, and when the blade 2 is assembled on the blade fork 1 through the quick-installation structure 3, the blocking member 33 cooperates with the blade fork 1 to clamp and lock the blade 2. During the factory assembly process of the utility model, the plug-in rod and the blocking member are fixedly installed on the blade fork to form an integral structure. Therefore, during the on-site assembly process of the utility model, it is only necessary to assemble the blade to the blade fork; during the on-site assembly, the staff operates the blade to align the plug-in hole with the corresponding end of the plug-in rod, and then operates the blade to move toward the side of the blade fork so that the blocking member passes through the plug-in hole and is fully or partially exposed outside the plug-in hole, that is, the plug-in hole is sleeved on the plug-in rod and is located between the blocking member and the blade fork. At this moment, the blocking member elastically deforms and resets to act on the upper surface of the blade, providing the blade with a force tending to move in the direction of the blade fork, so that the blocking member cooperates with the blade fork to clamp and lock the blade. For this reason, the utility model has the characteristics of convenient assembly and stable and reliable connection.

[0030] like Figure 1 , 4 As shown, the connecting lines between the three plug-in rods form a triangular connection structure.

[0031] like Figure 3 , 4 As shown, in order to improve the load-bearing capacity and structural stability, a mounting plate 11 is provided at the corresponding end of the blade fork 1, and the inner wall cross-section of the mounting plate 11 is arranged in an arc surface; a plurality of the plug-in rods 32 are arranged on the inner wall of the mounting plate 11 at circumferential intervals.

[0032] like Figure 3 As shown, for easy disassembly and assembly, a connecting protrusion 111 is provided on the inner wall of the mounting plate 11 , a threaded hole 112 is opened at the upper end of the connecting protrusion 111 , and the plug-in rod 32 is a plug-in screw for threaded connection with the threaded hole 112 .

[0033] When the blade 2 is assembled to the blade fork 1 through the quick-fit structure 3, the plug hole 31 is simultaneously sleeved on the plug rod 32 and the connecting protrusion 111, which can reduce the force of the blade on the plug rod and extend the service life of the plug rod; at the same time, the structural strength and stability between the blade and the blade fork are improved. Figure 3 , 4 As shown, the connecting protrusion 111 and the mounting plate 11 are an integral structure formed in one piece.

[0034] like Figure 3 ,4 As shown, the cross section of the connecting protrusion 111 is wide at the bottom and narrow at the top, which can avoid the upper end of the connecting protrusion 111 from interfering with the edge of the plug hole 31 and affecting the assembly effect, and is conducive to the plug hole 31 being smoothly sleeved on the connecting protrusion 111; at the same time, when the plug hole is assembled in the preset position, the outer wall of the connecting protrusion 111 and the lower edge of the plug hole 31 block and cooperate to prevent the blade from continuing to move toward the blade fork side. At this time, the upper edge of the mounting convex ring 113 is abutted against the lower surface of the blade 2, as shown in FIG. Figure 3 shown.

[0035] like Figure 3 , 4 As shown, in order to increase the contact area between the mounting plate and the blade to better support the blade, the edge of the mounting plate 11 has an upwardly protruding mounting convex ring 113, and when the blade 2 is assembled to the blade fork 1 through the quick-install structure 3, the mounting convex ring 113 abuts against the lower surface of the blade 2. Figure 3 As shown, when the mounting convex ring 113 is in abutment with the lower surface of the blade 2, the connecting protrusion 111, part of the plug-in rod 32 and part of the blocking member 33 are hidden by the space formed by the mounting plate 11 and the lower surface of the blade 2, making the overall appearance structure of the utility model more concise and neat.

[0036] Furthermore, the lower surface of the blade 2 has a positioning groove for the installation convex ring 113 to enter and position, which is not shown in the figure. In this embodiment, the installation convex ring 113 is positioned and matched with the positioning groove, which can make the connection between the installation plate and the blade more stable and reliable, and also reduce the force of the blade on the plug rod and the connection convex part.

[0037] like Figure 3-5 As shown, in order to better block the blade and avoid the gap between the plug hole and the plug rod, the blocking member 33 includes a blocking member body 331 sleeved on the plug rod 32, and the upper end of the blocking member body 331 is provided with a blocking cap body 332 used to cooperate with the blade fork 1 to clamp and lock the blade fork 1 when the blade 2 is assembled on the blade fork 1 through the quick-install structure 3. The cross-sectional width of the blocking cap body 332 is greater than the inner diameter of the plug hole 31. Figure 3 As shown, the blocking member body 331 is sleeved on the plug rod 32 and the connecting protrusion 111 to prevent the inner wall of the plug hole from directly making rigid contact with the two and causing mutual wear, thereby extending their service life and reducing maintenance and replacement costs.

[0038] like Figure 3-5 As shown, the upper end of the blocking cap body 332 is provided with a guiding inclined surface 3321, which can prevent the plug hole from interfering with the upper end of the blocking cap body and affecting the assembly effect through the guiding inclined surface and the guiding cooperation with the plug hole, thereby ensuring smooth assembly.

[0039] like Figure 3-5As shown, a blocking slope 3322 is provided at the lower end of the blocking cap body 332. When the blade 2 is assembled to the blade fork 1 through the quick-release structure 3, the blocking slope 3322 is partially located on the inner side of the plug-in hole 31, which is conducive to better acting on the upper surface of the blade (the upper edge of the plug-in hole), providing a force for the blade to move in the direction of the blade fork, so that the blocking member cooperates with the blade fork to clamp and lock the blade.

[0040] Furthermore, in order to improve the deformation effect and better compress the blades, the blocking member 33 is made of silicone or rubber.
