[0028] Example 1

[0029] Reference Figures 1-6For the first embodiment of the utility model, this embodiment provides the shutter bearing convenient to install, the shutter bearing convenient to install includes main part assembly 100, including shutter shaft 101, shutter shaft 101 outside is equipped with bearing 102.

[0030] Shutter shaft 101 provides support for the blade of the shutter, enabling the blade to rotate around it, thereby achieving the opening and closing and angle adjustment functions of the shutter, bearing 102 can convert the sliding friction between shutter shaft 101 and other components into rolling friction, greatly reducing the friction coefficient, making the rotation of shutter shaft 101 more smooth, reducing energy consumption, also reducing the wear of components due to friction, prolonging the service life of the shutter.

[0031] By directly placing shutter shaft 101 into the inner wall of bearing 102, and then adjusting bearing 102 to make it clamped with shutter shaft 101 to be fixed, shutter shaft 101 and bearing 102 can be installed.

[0032] Specifically, the fixing assembly 200 is arranged at one end of the bearing 102 and includes a fixing piece 201, four clamping rods 201a, support shafts 201b inserted into the inner walls of the clamping rods 201a, support frames 201c sleeved on the outer sides of the support shafts 201b, a rotating shaft 201d arranged on one side of the support frame 201c, a rotating disc 201e arranged at one end of the rotating shaft 201d, a clamping block 201f arranged on the inner wall of the rotating disc 201e, a fixing disc 201g sleeved on the outer side of the clamping block 201f, and a plurality of clamping grooves 201g-1 formed in the inner wall of the fixing disc 201g.

[0033] The rotating disc 201e is used to support the rotating shaft 201d, the inner wall of the shutter shaft 101 is provided with clamping grooves corresponding to the clamping rods 201a, the support shafts 201b are used to support the clamping rods 201a and are movably connected with the clamping rods 201a, and the number of the clamping rods 201a, the support shafts 201b and the support frames 201c is three.

[0034] When it is necessary to install the louver shaft 101 and the bearing 102, by moving the locking block 201f, the locking block 201f moves and separates from the locking groove 201g-1, and then the rotating disk 201e can be rotated. The rotating disk 201e drives the rotating shaft 201d to rotate. The rotation of the rotating shaft 201d can move the support frame 201c. The movement of the support frame 201c drives the support shaft 201b to move. The movement of the support frame 201c will also drive the clamping rod 201a to move. By moving the clamping rod 201a to engage with the locking groove on the louver shaft 101, the bearing 102 can be fixed to the louver shaft 101. Then, by releasing the locking block 201f, the locking block 201f re-engages with the locking groove 201g-1, thereby limiting the rotation disk 201e, thus completing the installation of the bearing 102 and the louver shaft 101.

[0035] When it is necessary to install the louver shaft 101 and the bearing 102, the locking block 201f is moved, and the locking block 201f moves and separates from the locking groove 201g-1. Then the rotating disk 201e can be rotated. The rotating disk 201e drives the rotating shaft 201d to rotate. The rotation of the rotating shaft 201d can move the support frame 201c. The movement of the support frame 201c will also drive the clamping rod 201a to move. The movement of the clamping rod 201a will engage with the locking groove on the louver shaft 101. After the clamping rod 201a moves to the required position, the locking block 201f is released, and the locking block 201f re-engages with the locking groove 201g-1, thereby limiting the rotation disk 201e and completing the installation of the bearing 102 and the louver shaft 101.

[0036] Example 2

[0037] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the fixing component 200 also includes a movable component 202, which includes a first spring 202a that is sleeved on the outside of the support shaft 201b. One end of the first spring 202a is fixed to one end of the clamping rod 201a, and the other end is fixed to the inner wall of the support frame 201c.

[0039] The fixed components 200 consist of three sets.

[0040] The movement of the support frame 201c drives the support shaft 201b to move. The movement of the support frame 201c also drives the clamping rod 201a to move. When one end of the clamping rod 201a is in contact with the louver shaft 101, it applies pressure to the first spring 202a. The installation of the louver shaft 101 is completed by the engagement of the clamping rod 201a with the louver shaft 101.

[0041] Specifically, a drive block 202b is provided at one end of the support frame 201c, and a positioning disk 202c is sleeved on the outside of the drive block 202b.

[0042] The other end of the positioning disk 202c is fixed to one end of the bearing 102 to support the drive block 202b. By moving the drive block 202b, the support frame 201c can be moved.

[0043] Specifically, both ends of the drive block 202b are provided with slide bars 202d, which slide on the inner wall of the positioning disk 202c.

[0044] The movement of the drive block 202b can drive the slider 202d to slide on the inner wall of the positioning disk 202c, so that the drive block 202b can slide stably.

[0045] Specifically, the inner wall of the positioning disk 202c is provided with a drive disk 202e, and the inner wall of the drive disk 202e is provided with a sliding groove 202e-1. The inner wall of the sliding groove 202e-1 is provided with a slider 202f, and the other end of the slider 202f is fixed to one end of the drive block 202b.

[0046] By rotating the drive disk 202e, the drive disk 202e rotates the slide groove 202e-1, which in turn drives the slider 202f to move through its guide. The movement of the slider 202f can then drive the drive block 202b to move up and down.

[0047] Specifically, the inner wall of the drive disc 202e is also provided with a toothed groove 202e-2, and a gear 202h is engaged at one end of the toothed groove 202e-2.

[0048] By rotating gear 202h, gear 202h will mesh with tooth groove 202e-2, causing drive disk 202e to rotate. The rotation of drive disk 202e will drive slide groove 202e-1 to rotate.

[0049] When the louver shaft 101 needs to be installed, the gear 202h is rotated. The gear 202h meshes with the tooth groove 202e-2, causing the drive disc 202e to rotate. The rotation of the drive disc 202e then drives the slide 202e-1 to rotate. The slide 202e-1 drives the three sliders 202f to move through its guide. The movement of the sliders 202f drives the three drive blocks 202b to move up and down. The movement of the drive block 202b can cause the slide bar 202d to slide on the inner wall of the positioning plate 202c. The movement of the drive block 202b can cause the three support frames 201c to move. The movement of the support frames 201c will also cause the three clamping rods 201a to move. When one end of the clamping rod 201a is in contact with the louver shaft 101, the clamping rod 201a will apply pressure to the first spring 202a. The clamping rod 201a engages with the locking groove on the louver shaft 101, thereby completing the installation.

[0050] When it is necessary to release the clamping of the louver shaft 101, the clamping rod 201a will separate from the louver shaft 101 by means of the reverse gear 202h. At this time, the clamping rod 201a can be returned to its original position by the rebound force of the first spring 202a for the next use.

[0051] Example 3

[0052] Reference Figures 5-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0053] Specifically, a rotating shaft 201d is inserted into the inner wall of the gear 202h, and the two ends of the rotating shaft 201d are also inserted into the inner wall of the positioning disk 202c for rotation.

[0054] By rotating the shaft 201d, the rotation of the shaft 201d can drive the gear 202h to mesh with the tooth groove 202e-2, thereby causing the drive disk 202e to rotate.

[0055] Specifically, the fixing component 200 also includes a limiting member 203, which includes a support rod 203a inserted into the inner wall of the locking block 201f. One end of the locking block 201f is also fixed with a second spring 203b, and the other end of the second spring 203b is fixed to the inner wall of the rotating disk 201e.

[0056] The support rod 203a is used to support the locking block 201f and is movably connected to it. When the limit on the rotating disk 201e is released, the locking block 201f is moved. The movement of the locking block 201f will squeeze the second spring 203b. The movement of the locking block 201f will also separate it from the slot 201g-1. Then, by moving the support rod 203a, the rotating disk 201e can be driven to rotate. The rotation of the rotating disk 201e can cause the rotating shaft 201d to rotate.

[0057] Specifically, one end of the card block 201f is fixed with a handle 203c.

[0058] By moving the handle 203c, the block 201f can be moved.

[0059] Specifically, two fixing posts 203d are fixed to one end of the fixing plate 201g, and the other end of the fixing post 203d is fixed to one end of the positioning plate 202c.

[0060] The fixing column 203d is used to support the fixing plate 201g and prevent the fixing plate 201g from falling off due to lack of support.

[0061] In use, when it is necessary to fix the louver shaft 101 to the bearing 102, the louver shaft 101 is placed into the bearing 102, and then the handle 203c is moved. The movement of the handle 203c causes the locking block 201f to move. The movement of the locking block 201f will compress the second spring 203b. When the locking block 201f moves, it will separate from the locking groove 201g-1. Then, by moving the support rod 203a, the support rod 203a can drive the rotating disk 201e to rotate. The rotating disk 201e drives the rotating shaft 201d to rotate. The rotation of the rotating shaft 201d can drive the gear 202h to mesh with the tooth groove 202e-2, thereby causing the drive disk 202e to rotate. The rotation of the drive disk 202e will drive the slide groove 202e-1 to rotate. The slide groove 202e-1 drives the three sliders 202f to move through its guide. The movement of block 202f can drive the three drive blocks 202b to move up and down. The movement of drive blocks 202b can drive the slide bar 202d to slide on the inner wall of the positioning plate 202c. The movement of drive blocks 202b can drive the three support frames 201c to move. The movement of support frames 201c can also drive the three clamping rods 201a to move. When one end of clamping rod 201a is in contact with the louver shaft 101, clamping rod 201a will apply pressure to the first spring 202a. The clamping rod 201a engages with the locking groove on the louver shaft 101, thereby completing its fixation. After the fixation is completed, when it is necessary to limit the rotation plate 201e, by releasing the movement of handle 203c, the force of the rebound of the second spring 203b can make the locking block 201f re-engage with the locking groove 201g-1, thereby completing the installation of the louver shaft 101.

[0062] When it is necessary to release the clamping of the louver shaft 101, the limit of the rotating disk 201e is released again, and then the gear 202h is reversed. The rotation of the gear 202h can move the clamping rod 201a to separate from the engagement groove on the louver shaft 101. At this time, the force of the first spring 202a can return the clamping rod 201a to its original position for the next use.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
