DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-6 The utility model provides a technical solution: a quick-connect reducer cover, comprising a reducer 1, an output shaft 3 is sleeved inside the reducer 1, a connecting port 2 is arranged on the front of the reducer 1, and a reducer cover 4 is movably installed on one side of the connecting port 2, a limiting groove 5 is arranged inside the connecting port 2, a fixing rod 6 and a clamping assembly 8 are arranged in a circular array on the front of the connecting port 2, three connecting ears 9 are arranged in a circular array outside the reducer cover 4, and a countersunk hole 10 and a connecting hole 12 are arranged on the back of the connecting ear 9, and a mounting hole 11 is arranged inside the countersunk hole 10, and an axial hole 13 is arranged in the middle of the reducer cover 4, and the axial hole 13 passes through the connecting port 2, a limiting block 14 is fixedly installed on the back of the reducer cover 4, and a sealing gasket 15 is installed on the outer wall of the back of the reducer cover 4, and a clamping hole 16 is arranged on the front of the connecting ear 9.

[0026] The limit block 14 and the sealing gasket 15 can be installed respectively through the reducer cover 4. Since the back of the connecting ear 9 is provided with a countersunk hole 10 and a connecting hole 12, and the interior of the countersunk hole 10 is provided with a mounting hole 11, the reducer cover 4 can be easily installed to the surface of the connecting port 2 through the countersunk hole 10 and the connecting hole 12, and the limit block 14 is allowed to enter the limit groove 5 by pushing the reducer cover 4. At this time, the fixing rod 6 is inserted into the interior of the connecting hole 12, and the clamping assembly 8 is inserted into the interior of the mounting hole 11, and is extended and clamped in the interior of the clamping hole 16 through the clamping assembly 8. At this time, the sealing gasket 15 contacts the connecting port 2, and the clamping assembly 8 fixes the connecting port 2 and the reducer cover 4. When the reducer cover 4 is removed, the clamping assembly 8 is pushed to disengage the clamping assembly 8 from the clamping hole 16. The clamping assembly 8 contacts and limits the reducer cover 4, and the reducer cover 4 can be removed. The setting of the countersunk hole 10 and the clamping hole 16 prevents the clamping assembly 8 from protruding from the surface of the reducer cover 4.

[0027] See alsoFigure 2 , Figure 3 , the number of the clamping components 8 is three. The three clamping components 8 penetrate through the inside of the mounting hole 11, and the fixing rod 6 penetrates through the inside of the mounting hole 11, and the limiting block 14 is clamped inside the limiting groove 5. The inner diameter value of the shaft hole 13 is adapted to the outer diameter value of the output shaft 3, and the connection port 2 penetrates through the inside of the shaft hole 13.

[0028] Through the three clamping components 8, it is convenient to stably install the reducer cover 4. And through the fixing rod 6 penetrating through the inside of the mounting hole 11, the fixing rod 6 is convenient for positioning the reducer cover 4. At the same time, the clamping component 8 penetrates through the inside of the mounting hole 11, so that the clamping component 8 extends and is clamped inside the clamping hole 16. Furthermore, the connection port 2 and the reducer cover 4 are fixed through the clamping component 8.

[0029] Refer to Figure 2 , Figure 3 , the limiting block 14 is adapted to the limiting groove 5, and the limiting block 14 and the limiting groove 5 are kept horizontal. A convex block is fixedly installed on one side of the limiting block 14, and the convex block is clamped inside the limiting groove 5.

[0030] By keeping the limiting block 14 and the limiting groove 5 horizontal, when the reducer cover 4 is pushed, the reducer cover 4 drives the limiting block 14 into the inside of the limiting groove 5. Furthermore, the fixing rod 6 is inserted into the inside of the connection hole 12, and the clamping component 8 is clamped inside the mounting hole 11. And due to a convex block being fixedly installed on one side of the limiting block 14, it is convenient to position and install the reducer cover 4.

[0031] Refer to Figure 2 , Figure 6 , the clamping component 8 includes a pin 801. The pin 801 is fixedly installed on the front surface of the connection port 2. Slots 802 are opened on both the left and right sides inside the pin 801. At the same time, a clamping block 803 is hinged at the top of the slot 802. The inner side of the clamping block 803 is fixedly connected with a spring 804, and the other end of the spring 804 is fixedly connected with the inside of the slot 802.

[0032] The reducer cover 4 can be fixed through the pin 801 in the clamping component 8. Since slots 802 are opened on both the left and right sides inside the pin 801, and the clamping block 803 is hinged at the top of the slot 802, when the clamping component 8 is inserted into the mounting hole 11, the mounting hole 11 compresses the clamping block 803 to rotate around the hinged position at the top of the clamping block 803, so that the bottom of the clamping block 803 contracts towards the inside of the slot 802, and the bottom of the clamping block 803 compresses the spring 804. After the pin 801 is inserted to a certain position, the spring 804 pushes the clamping block 803 to reset. At this time, the clamping block 803 contacts the clamping hole 16, and thus the reducer cover 4 can be fixed.

[0033] During operation, the limit block 14 and the gasket 15 can be installed through the reducer cover 4 respectively. Since a counterbore 10 and a connection hole 12 are provided on the back of the connecting ear 9, and an installation hole 11 is provided inside the counterbore 10, it is convenient to install the reducer cover 4 on the surface of the connection port 2 through the counterbore 10 and the connection hole 12. By pushing the reducer cover 4, the limit block 14 enters the inside of the limit groove 5. At this time, the fixing rod 6 is inserted into the inside of the connection hole 12, and the clamping component 8 is inserted into the inside of the installation hole 11, and the clamping component 8 extends and is clamped inside the clamping hole 16. At this time, the gasket 15 contacts the connection port 2, and the clamping component 8 fixes the connection port 2 and the reducer cover 4. When the reducer cover 4 is removed, the clamping component 8 is pushed to make the clamping component 8 disengage from the clamping hole 16, and the clamping component 8 limits the contact of the reducer cover 4, so that the reducer cover 4 can be removed. And through the settings of the counterbore 10 and the clamping hole 16, it is prevented that the clamping component 8 protrudes from the surface of the reducer cover 4.

[0034] Through the three clamping components 8, it is convenient to stably install the reducer cover 4. And through the fixing rod 6 passing through the inside of the installation hole 11, it is convenient for the fixing rod 6 to position the reducer cover 4. At the same time, the clamping component 8 passes through the inside of the installation hole 11, so that the clamping component 8 extends and is clamped inside the clamping hole 16, and then the connection port 2 and the reducer cover 4 are fixed through the clamping component 8.

[0035] By keeping the limit block 14 and the limit groove 5 horizontal, when the reducer cover 4 is pushed, the reducer cover 4 drives the limit block 14 to enter the inside of the limit groove 5. Then the fixing rod 6 is inserted into the inside of the connection hole 12, and the clamping component 8 is clamped inside the installation hole 11. And a convex block is fixedly installed on one side of the limit block 14, which makes it convenient to position and install the reducer cover 4.

[0036] The reducer cover 4 can be fixed by the pin 801 in the clamping component 8. Since clamping grooves 802 are provided on the left and right sides inside the pin 801, and a clamping block 803 is hinged at the top of the clamping groove 802, when the clamping component 8 is inserted into the installation hole 11, the installation hole 11 compresses the clamping block 803 to rotate around the hinge at the top of the clamping block 803, so that the bottom of the clamping block 803 contracts into the inside of the clamping groove 802, and the bottom of the clamping block 803 compresses the spring 804. When the pin 801 is inserted into a certain position, the spring 804 pushes the clamping block 803 to reset. At this time, the clamping block 803 contacts the clamping hole 16, and then the reducer cover 4 can be fixed.

[0037] In summary, the device pushes the reducer cover 4 to drive the limit block 14 into the limit groove 5. At this time, the fixing rod 6 is inserted into the connection hole 12, and the clamping component 8 is inserted into the installation hole 11 and extends to be clamped in the clamping hole 16 through the clamping component 8. At this time, the clamping component 8 fixes the connection port 2 and the reducer cover 4. By pushing the clamping component 8, the clamping component 8 is disengaged from the clamping hole 16, and the clamping component 8 limits the contact with the reducer cover 4, so that the reducer cover 4 can be removed.
