The quick-connect support inner side plate and the quick-connect support outer side plate are provided with a second locking groove at the bottom near the rear end of the quick-connect support inner side plate and the quick-connect support outer side plate. The four second locking grooves are symmetrically arranged from left to right. By designing the quick-connect support side plate as a double-layer structure, the overall thickness of the second locking grooves on both sides can be increased, so that it can easily withstand the tensile force brought by the excavator bucket during operation and extend its service life.

[0028] 3. By providing a limiting baffle at the rear end between the two quick-connect support side plates, during the bucket installation process, the rear end of the limiting baffle is inserted into the upper end of the second locking groove to lock and limit the bucket connecting rod inside the second locking groove. This prevents the connecting rod inside the second locking groove from falling outward during the bucket installation process, thus ensuring the smooth completion of the bucket installation work.

[0039] The present invention will be further described below with reference to the embodiments.

[0040] pass Figures 1-8 As can be seen, the excavator swing-type quick connector assembly with anti-detachment structure includes a connecting rod fixing seat assembly 1, a swing cylinder 2, and a quick-connect assembly 3. The connecting rod fixing seat assembly 1 is located at the upper end of the swing cylinder 2 and is fixedly connected to the swing cylinder 2. The quick-connect assembly 3 is located at the lower end of the swing cylinder 2 and is rotatably connected to the swing cylinder 2.

[0041] The connecting rod fixing seat assembly 1 is provided with a connecting rod fixing shaft support plate 102, and a connecting rod fixing shaft 101 is fixedly provided on the connecting rod fixing shaft support plate. The connecting rod fixing shaft 101 is used to connect and fix with the boom connecting rod of the excavator. A first support seat plate 201 is fixedly provided on the outer side of the outer shell of the swing cylinder 2. The first support seat plate 201 is fixedly connected to the connecting rod fixing shaft support plate 102. Second support seat plates 202 are fixedly provided on both sides of the main shaft of the swing cylinder 2. When the main shaft swings left and right, it can drive the second support seat plates 202 to swing synchronously. The quick-connect assembly 3 includes quick-connect support side plates 301. The quick-connect support side plates 301 are located on the left and right sides of the quick-connect assembly 3 respectively. The upper ends of the two quick-connect support side plates 301 are fixedly connected to the second support seat plates 202. The swing cylinder 2 can drive the quick-connect assembly 3 to swing left and right.

[0042] A second locking groove 303 is provided at the bottom of the quick-connect support side plate 301 near the rear end. The opening of the second locking groove 303 faces the rear side, and the bottom edge of the second locking groove 303 is curved upward. A locking support assembly 302 is provided between the two quick-connect support side plates 301 at the front end. A first locking groove 30205 is provided at the lower section of the locking support assembly 302. The opening of the first locking groove 30205 faces the front side. The first locking groove 30205 and the second locking groove 303 can be used to achieve lateral locking with the two fixing rods at the top of the bucket.

[0043] In particular, because the bottom edge of the second locking groove 303 is bent upward, the opening of the second locking groove 303 faces the rear and upward. When the second locking groove 303 hooks with the fixing rod of the bucket, the fixing rod of the bucket is not easy to fall off from the second locking groove 303 due to the blocking effect of the inclined side of the second locking groove 303, thus ensuring the smooth installation of the bucket.

[0044] A push-pull device is provided in the middle between the two quick-connect support side plates 301. The push-pull device is fixedly connected to the locking support assembly 302. The push-pull device can drive the locking support assembly 302 to slide back and forth, so as to realize the quick installation of the bucket.

[0045] A limiting baffle 305 is provided at the rear end between the two quick-connect support side plates 301. The limiting baffle 305 is fixedly connected to the locking support assembly 302. The locking support assembly 302 can drive the limiting baffle 305 to slide back and forth. When the limiting baffle 305 slides backward, it can enter the upper end of the second locking groove 303 to lock and limit the bucket connecting rod inside the second locking groove 303.

[0046] There are two connecting rod fixing shaft support plates 102, which are located on the left and right sides of the connecting rod fixing seat assembly 1, respectively. There are two connecting rod fixing shafts 101, which are located between the connecting rod fixing shaft support plates 102 on both sides, close to the front and rear sides. The two connecting rod fixing shafts 101 are used to connect and fix to the boom of the excavator.

[0047] In one embodiment, the locking support assembly 302 is composed of a fixed connecting section 30201, a sliding connecting section 30202, and a locking section 30203. The fixed connecting section 30201 is located at the upper section of the locking support assembly 302, the sliding connecting section 30202 is located at the middle section of the locking support assembly 302, and the locking section 30203 is located at the lower section of the locking support assembly 302.

[0048] The push-pull device is a linear hydraulic cylinder 304. A connecting support block 310 is fixedly provided between the two quick-connect support side plates 301 at the rear end of the linear hydraulic cylinder 304. The rear end of the linear hydraulic cylinder 304 is fixedly connected to the connecting support block 310. The piston rod of the linear hydraulic cylinder 304 is fixedly connected to the fixed connecting section 30201. The left and right sides of the sliding connecting section 30202 are respectively provided with second sliding grooves 30204. The inner ends of the two quick-connect support side plates 301 are respectively fixedly provided with sliders 307 at the front end. The sliders 307 are slidably connected to the second sliding grooves 30204. The linear hydraulic cylinder 304 can drive the locking support assembly 302 to slide back and forth along the sliders 307. The first locking groove 30205 is located at the front end of the locking section 30203 and the opening direction is facing forward.

[0049] The linear hydraulic cylinder 304 can be replaced with other push-pull devices with push-pull functions, such as lead screws, electric push rods, and pneumatic cylinders.

[0050] In one embodiment, a connecting rod 306 is provided between the sliding connecting section 30202 and the limiting baffle 305. The front end of the connecting rod 306 is fixedly connected to the rear end of the sliding connecting section 30202, and the rear end of the connecting rod 306 is fixedly connected to the front end of the limiting baffle 305. The inner ends of the two quick-connect support side plates 301 are respectively provided with first sliding grooves 30103 at the rear end. The limiting baffle 305 is slidably connected to the first sliding grooves 30103. The connecting rod 306 can drive the limiting baffle 305 to slide back and forth along the first sliding grooves 30103. By setting the connecting rod 306, the synchronous back and forth sliding of the locking support assembly 302 and the limiting baffle 305 can be realized, and the installation of the bucket can be completed.

[0051] In one embodiment, the limiting baffle 305 has a chamfer 30501 at the connection between the front end and the lower end. During the installation of the bucket, when the bucket connecting rod enters the second locking groove 303, the chamfer 30501 guides the bucket connecting rod smoothly into the interior of the second locking groove 303, preventing the bucket connecting rod from causing impact damage to the limiting baffle 305 and extending its service life.

[0052] To increase the load-bearing capacity of the second locking groove 303, the following embodiment is adopted:

[0053] In this embodiment, the quick-connect support side plate 301 is composed of a quick-connect support inner side plate 30101 and a quick-connect support outer side plate 30102. The rear sections of the quick-connect support inner side plate 30101 and the quick-connect support outer side plate 30102 are fixedly connected to each other. A second locking groove 303 is provided on the quick-connect support inner side plate 30101 and the quick-connect support outer side plate 30102 at the bottom near the rear end. The four second locking grooves 303 are symmetrically arranged from left to right. By designing the quick-connect support side plate 301 as a double-layer structure, the overall thickness of the second locking grooves 303 on both sides can be increased, so that it can easily withstand the pulling force brought by the bucket during operation and extend its service life.

[0054] To increase the stability of the quick-connect support inner plate 30101 and quick-connect support outer plate 30102, the following embodiment is adopted:

[0055] In this embodiment, a reinforcing support plate 311 is fixed between the two quick-connect support inner side plates 30101. The reinforcing support plate 311 forms an integrated structure of the quick-connect support side plates 301 on the left and right sides, so as to achieve uniform force on both sides and increase the stability and compressive strength of the overall structure.

[0056] In one embodiment, the fixed connecting section 30201 has support holes 30206 extending from front to back on both the left and right sides. The two support holes 30206 are respectively provided with connecting shafts 308. The connecting shafts 308 are slidably connected to the support holes 30206. The ends of the two connecting shafts 308 away from the support holes 30206 are respectively fixedly connected to the quick-connect support inner side plate 30101. Through the supporting effect of the connecting shafts 308, the piston shaft can be prevented from shaking when driving the locking support assembly 302 to slide back and forth, thereby further increasing the smoothness of the sliding of the locking support assembly 302 and the accuracy of the connection between the locking support assembly 302 and the bucket fixing rod.

[0057] In one embodiment, springs 309 are respectively provided on the outer circumference of the two connecting shafts 308 between the fixed connecting section 30201 and the quick-connect support inner plate 30101. The fixed connecting section 30201 and the quick-connect support inner plate 30101 are elastically supported by the springs 309. The springs 309 play an important role in the entire quick-connect assembly 3 structure. After the first locking groove 30205 and the second locking groove 303 are locked and fixed with the two fixed rods at the upper end of the bucket, the springs 309 are continuously in an open support state between the fixed connecting section 30201 and the quick-connect support inner plate 30101. During normal operation of the bucket, when the linear cylinder 304 fails, the springs 309 can maintain the quick-connect assembly 3 and the bucket in a clamped state, avoiding the situation where the connection between the quick-connect assembly 3 and the bucket becomes loose due to the failure of the linear cylinder 304, or even the bucket falling off, thus avoiding related safety hazards.

[0058] In one embodiment, the front and rear ends of the two quick-connect support side plates 301 are respectively provided with a quick-connect support front guard plate 312 and a quick-connect support rear guard plate 313. The quick-connect support front guard plate 312 is fixedly connected to the front end of the two quick-connect support side plates 301, and the quick-connect support rear guard plate 313 is fixedly connected to the rear end of the two quick-connect support side plates 301. The quick-connect support side plates 301, quick-connect support front guard plate 312, and quick-connect support rear guard plate 313 together form an enclosed structure, which can prevent external forces from causing bumps and damage to the internal components during operation.

[0059] In the installation of this swing-type quick connector assembly, firstly, according to the placement angle of the bucket, the angle of the quick connector assembly 3 is adjusted by the swing cylinder 2. Then, the piston shaft on the linear cylinder 304 is moved forward. Simultaneously, the piston shaft slides forward, causing the locking support assembly 302 and the limit baffle 305 to slide forward synchronously. At this point, the rearmost position of the limit baffle 305 disengages from the second locking groove 303. Next, the excavator boom is manipulated to bring the second locking groove 303 closer to one of the connecting rods on the bucket until the connecting rod falls into the bottom of the second locking groove 303. Finally, the piston shaft on the linear cylinder 304 is moved backward. Simultaneously, the piston shaft moves backward, causing the locking support assembly 302 and the limit baffle 305 to slide forward synchronously. After sliding backward, the rear end of the limiting baffle 305 enters the upper part of the second locking groove 303, locking and limiting the bucket connecting rod inside the second locking groove 303 to prevent the connecting rod inside the second locking groove 303 from falling outward. Then, the excavator boom presses down, pressing the first locking groove 30205 to the position of the other connecting rod of the bucket. Then, the piston shaft on the linear cylinder 304 is moved forward again, driving the first locking groove 30205 forward until it is tightly fitted with the corresponding bucket connecting rod. At this time, the limiting baffle 305 disengages from the second locking groove 303 again. The second locking groove 303 and the first locking groove 30205 provide opposing support and locking for the bucket connecting rod, finally completing the bucket installation process.

[0060] During this process, since the second locking groove 303 and the first locking groove 30205 provide opposing support and locking for the bucket connecting rod, even if the limit baffle 305 disengages from the second locking groove 303, the connecting rod will not fall off.

[0061] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
