DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 The worm 6 and the worm gear 5 are connected to each other, and the worm 6 is engaged with the two groups of worm gears 5. The worm 6 penetrates the protective cover 4 and is connected to the handle 8. The screw 7 penetrates the protective cover 4 and the bottom plate 2 and extends into the mounting groove. A pressing plate 9 is also provided in the mounting groove. Two groups of screw grooves threadedly connected to the corresponding screw 7 are provided on the pressing plate 9.

[0025] The shape and size of the mounting slot allow it to accommodate built-in reducers of different specifications (within a certain range). During installation, the reducer can be simply inserted upward from the lower opening of the mounting slot, which is relatively simple to operate. This universal design takes advantage of the spatial tolerance of the mounting slot. As long as the reducer's external dimensions can fit the internal space of the mounting slot, it can be placed. There is no need to customize a different load-bearing structure for each specific size of reducer, making it convenient to use this mounting base to install different models of built-in reducers in a variety of application scenarios.

[0026] The output hole on the top wall of the housing 1 is designed to meet the power output requirements of the built-in reducer. Once the reducer is installed in the mounting slot, its power output shaft and other related output components can pass through the housing 1 through this output hole and then connect to external equipment to be driven (such as the drive roller of a conveyor belt, the joint transmission components of a robotic arm, etc.), ensuring smooth power transmission and achieving normal operation of the entire equipment.

[0027] The connectors symmetrically arranged on the left and right sides of the bottom wall of the cover body 1 are used to connect with the connection frame 3 of the closing component, so that the bearing component and the closing component form an integral structure, which together provide a stable support environment for the built-in reducer;

[0028] The bottom plate 2 in the closed assembly serves as the bottom basic support structure of the entire mounting base. The connection frames 3 symmetrically arranged on the left and right sides are connected to the connectors of the load-bearing assembly, ensuring uniform force when connected to the load-bearing assembly, making the overall structure more stable. The protective cover 4 arranged below the bottom plate 2, firstly, protects the transmission components inside it, preventing external dust, moisture, debris, etc. from entering the interior and affecting the normal operation of the transmission components (such as the worm 6, worm wheel 5, etc.), thereby extending the service life of these components; secondly, together with the bottom plate 2, it provides further support for the built-in reducer installed above, thereby enhancing the load-bearing capacity of the entire mounting base for the reducer, preventing the reducer from loosening, shifting, or even being damaged due to unexpected external force impacts (such as equipment vibration, minor collisions, etc.) during operation, and ensuring that the reducer is in a stable working environment;

[0029] The worm 6, two sets of worm wheels 5, screw 7, handle 8, and pressure plate 9, housed within the protective cover 4, together form an adjustable fixing system. The worm 6 meshes with the two sets of worm wheels 5. When the operator grasps the friction grooves 15 on the handle 8 (which increase the friction between the hand and the handle 8, facilitating force application and stable rotation of the handle 8) and turns the handle 8, the worm 6 drives the worm wheel 5 to rotate according to the transmission principle of the worm wheel 5 and worm 6. Due to the corresponding connection between the worm wheel 5 and screw 7,

[0030] The rotation of the worm gear 5 drives the screw 7 to rotate synchronously, and the screw 7 passes through the protective cover 4 and the base plate 2 and extends into the mounting groove of the bearing assembly cover 1. The pressure plate 9 in the mounting groove is provided with two sets of screw grooves that are threadedly connected to the corresponding screws 7;

[0031] When it is necessary to fix the built-in reducer installed in the mounting groove, the handle 8 is turned forward to drive the worm 6, worm wheel 5, and screw 7 to rotate in sequence. During the rotation of the screw 7, due to its threaded connection with the screw groove on the pressure plate 9, the pressure plate 9 will move downward along the axial direction of the screw 7. The pressure plate 9 gradually approaches and finally presses tightly on the built-in reducer. The pressure exerted by the pressure plate 9 on the reducer can achieve a firm fixation of the reducer, ensuring that it will not shake or shift during operation, thereby ensuring the stability of the support. According to the structure of the reducer, a suitable pressure plate 9 can be selected for assembly.

[0032] The connecting member includes an insert block 10, an elastic member and a card block 11. The connecting frame 3 is symmetrically provided with card holes on the front and rear sides. The insert block 10 is also symmetrically provided with movable grooves on the front and rear sides. The two ends of the elastic member are respectively connected to the inner wall of the movable groove and the card block 11. The elastic member includes a spring 12 and a telescopic rod 13. The spring 12 is sleeved on the telescopic rod 13. Both ends of the spring 12 and the telescopic rod 13 are respectively connected to the inner wall of the movable groove and the card block 11. The card block 11 is also provided with an inclined surface 14 at one end close to the cover body 1, and a hollow hole 16 is provided on the side wall of the cover body 1. The connecting member is composed of an insert block 10, an elastic member (including a spring 12 and a telescopic rod 13 sleeved on the spring 12, the spring 12 provides elastic force to enable the card block 11 to be telescopic, and the telescopic rod 13 ensures that the telescopic direction of the card block 11 is stable) and the card block 11. When connecting the load-bearing assembly to the closure assembly, the connector's insert 10 is aligned with the corresponding position of the closure assembly's connecting frame 3 and inserted. During the insertion of the insert 10, the inclined surface 14 on the clamping block 11 near the end of the housing 1 first contacts the edge of the connecting frame 3. Due to the guiding effect of the inclined surface 14, the connecting frame 3 applies a squeezing force to the clamping block 11 into the movable groove, causing the clamping block 11 to retract into the movable groove, overcoming the elastic force of the elastic member. As the insert 10 continues to be inserted, when the clamping block 11 moves to the corresponding latching hole position on the connecting frame 3, the elastic force of the elastic member automatically ejects the clamping block 11 and locks it into the latching hole, thus firmly connecting the connector to the connecting frame 3. This allows the load-bearing assembly to be securely attached to the closure assembly, laying the foundation for the subsequent installation and fixation of the built-in reducer. This connection method also facilitates subsequent disassembly. Simply press the clamping block 11 to retract it, and the insert 10 can be pulled out of the connecting frame 3 to separate the two. This is simple and convenient operation. In addition, the hollow holes 16 provided on the side wall of the cover body 1 can, on the one hand, reduce the weight of the cover body 1 itself, and on the other hand, facilitate internal air circulation during the operation of the reducer, help the reducer to dissipate heat, ensure its stable performance, and avoid affecting the service life and working efficiency of the reducer due to overheating.
