[0002] The shaft connection support refers to a box-type slider, which is used to fix and install linear bearings and is a linear motion guide component used in conjunction with the optical axis.

[0003] The Chinese patent with the announcement number CN212899405U discloses a box-type slider, including a box body and a linear bearing detachably arranged in the box body, and a limit component is arranged on both sides of the box body to prevent the linear bearing from slipping off from both ends of the box body, and an adjustment device for ensuring the center position of the linear bearing is also arranged in the box body, and a circular through groove with an inner diameter slightly larger than the outer diameter of the linear bearing for installing the linear bearing is arranged in the box body, and limit strips are arranged on both sides of the opening of the circular through groove for placing the linear bearing in the circumferential and axial rotation. The limit strips and the circular through groove are The groove is fixedly connected, the limiting component includes a limiting ring and a clamping ring, the limiting ring is arranged in the circular through groove, the limiting ring is fixedly connected to one side of the circular through groove, arc-shaped grooves are respectively arranged on both sides of the circular through groove, the clamping ring is detachably arranged in the groove away from the limiting ring, the adjusting component includes a limiting groove, an elastic member and a clamping strip, the length direction of the limiting groove is parallel to the axis of the circular through groove, the cross-section of the limiting groove is convex, the length of the clamping strip is consistent with the length of the limiting groove, the bottom of the clamping strip is connected to the limiting groove through an elastic member, and the elastic member is a compression spring.

[0004] The above structure can remove the linear bearing installed in the circular through groove for replacement by disassembling the retaining ring in the circular through groove, but the inner diameter of the circular through groove is fixed, so the diameters of the installed linear bearings are the same. If the diameter of the linear bearing to be installed changes, the entire box-type slider needs to be replaced, resulting in lower applicability. Utility Model Content

[0005] The utility model provides a shaft connection support in view of the disadvantage that the linear bearings replaced in the prior art can only have the same diameter as before the replacement. If the diameter of the linear bearing to be installed changes, the entire box-type slider needs to be replaced, resulting in low applicability.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] A shaft connection support includes a box body, a mounting hole for mounting a shaft and a bearing is arranged in the box body, an adjustment component for adjusting the diameter of the mounting hole is arranged on a side wall of one side of the box body, the adjustment component includes a slot opened on the side wall of one side of the box body and connected to the mounting hole, and a plurality of locking components for driving the two side walls of the slot to approach each other are arranged on the box body.

[0008] By adopting the above scheme, the provided mounting holes can be used to install shafts and bearings. When the bearing needs to be installed in the mounting holes, the bearing can be inserted into the mounting holes first. Thereafter, the side walls on both sides of the slot are driven close to each other by the locking components provided on the housing, thereby clamping the bearing inserted into the mounting holes. If the diameter of the bearing in the mounting holes changes after replacement, the locking components can also be used after installation to drive the side walls on both sides of the slot close to each other, thereby clamping the replaced bearing, thereby improving its applicability.

[0009] Preferably, the locking component comprises a socket which is arranged on the box body perpendicular to the slot and passes through the box body, a bolt which drives the two side walls of the slot closer to each other is inserted in the socket, and a nut which matches the bolt is arranged at the bottom of the socket.

[0010] By adopting the above scheme, after the bearing is installed in the mounting hole, the bolt or nut can be rotated to make the nut gradually screw into the threaded section of the bolt. At this time, the bolt head and the nut will exert pressure on the two side walls of the slot, causing them to deform and approach each other. At this time, the two side walls of the slot will drive the box to clamp the bearing installed in its mounting hole. Since the diameter of the mounting hole can be changed by the bolt and the nut exerting pressure on the two side walls of the slot, the applicability of the shaft connection bracket is improved.

[0011] Preferably, the bolt comprises a bolt head in the shape of an outer hexagon and a threaded section, and a receiving component for receiving and limiting the rotation of the bolt head is provided near the bolt head in the box.

[0012] Preferably, the storage component includes a storage groove which is arranged on the box body near the bolt head and has the same width as the bolt head.

[0013] By adopting the above scheme, the receiving groove can be used to receive the bolt head, and the width of the receiving groove is set to be the same as the bolt head, so that the bolt head cannot rotate after being installed in the receiving groove, thereby facilitating the nut to be screwed into the threaded section of the bolt.

[0014] Preferably, the depth of the receiving groove is greater than or equal to the thickness of the bolt head, and an anti-dropping component for covering the receiving groove and preventing the bolt head from falling out of the receiving groove is provided at the opening end of the receiving groove.

[0015] Preferably, the anti-drop component includes a cover plate arranged on the top of the storage slot, and a limiting component is provided between the cover plate and the box body for limiting the cover plate when the cover plate is closed on the top of the storage slot.

[0016] By adopting the above scheme, the set cover plate can be covered on the top of the storage groove after the bolt head is inserted into the storage groove, thereby hiding the bolt head, thereby increasing the overall beauty of the shaft connection support, and the set limiting component can limit the cover plate when the cover plate is covered on the top of the storage groove to prevent it from moving after it is covered on the top of the storage groove. At the same time, it can also limit the bolt head in the storage groove to prevent the bolt head from falling out of the storage groove when the nut is screwed into the threaded section of the bolt, thereby making it easier for the user to screw the nut into the threaded section of the bolt.

[0017] Preferably, the limiting component comprises elastic hooks respectively arranged on both sides of the cover plate, and slots for partially engaging the elastic hooks are arranged on the side walls of both sides of the box body at positions opposite to the elastic hooks.

[0018] By adopting the above scheme, the elastic hooks can be partially engaged in the slots on both sides of the box body when the cover is closed on the top of the storage slot, thereby limiting the cover and preventing it from moving when it is closed on the top of the storage slot.

[0019] The utility model has significant technical effects due to the adoption of the above technical scheme: the provided mounting holes can be used to install shafts and bearings, and when the bearings need to be installed in the mounting holes, the bearings can be first inserted into the mounting holes, and then the side walls on both sides of the slots can be driven close to each other by the locking components provided on the housing, thereby clamping the bearings inserted into the mounting holes; if the diameter of the bearings in the mounting holes changes after replacement, the locking components can also be used after the bearings are installed to drive the side walls on both sides of the slots close to each other, thereby clamping the replaced bearings, thereby improving the applicability of the utility model.
