Technical Field

[0001] The utility model relates to the technical field of roller brackets, in particular to a detachable roller bracket. Background Art

[0002] As a rolling component, the roller is often used in scenarios where resistance and noise are reduced. There are many ways to install the roller in the prior art, but all of them are to fix the roller bearing to the mounting column, which is then connected to the roller bracket through the mounting column. The mounting column is usually installed by riveting, welding, or threaded locking. This installation method does not pose great difficulty in installation or disassembly for a structure that is transparent on both sides.

[0003] However, some rollers in the prior art, such as rubber-coated bearings, are installed on the roller bracket in a single-sided installation manner; and this installation manner is usually to extend the roller into the guide rail from the side to ensure connection stability and support performance; taking the sliding column of the side curtain car as an example, the sliding column is an integral type, and one or both ends of the sliding column are riveted to the mounting column of the rubber-coated bearing, and then the rubber-coated bearing is extended into the guide rail installed on the car; the rubber-coated bearing is a wearing part, and the sliding column is a commonly used part, so when the rubber-coated bearing is damaged; because the rubber-coated bearing extends into the guide rail laterally, the installation and disassembly working surface is located at the innermost side of the guide rail, there is no operating space, and the disassembly is inconvenient. When replacing, it is necessary to disassemble the side curtain cloth and the sliding column as a whole before the rubber-coated bearing can be disassembled and replaced as a whole. In particular, the sliding column is relatively large in size and weight, which will cause the problem of complex disassembly and high labor intensity;

[0004] Therefore, in order to solve the problem that the installation and disassembly working surface of the roller extending into the guide rail or guide groove from one side is blocked and thus the disassembly is difficult, a detachable roller bracket is proposed. Utility Model Content

DETAILED DESCRIPTION

[0037] 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 of 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. Specific embodiment 1

[0039] See also Figure 1-3 As shown, the utility model is a detachable roller bracket, comprising a connecting bracket 1, a clamping block 2 and a rolling part 3, wherein:

[0040] The rolling part 3 includes a mounting column 31 and a connecting column 32. The connecting column 32 is fixedly connected to one end of the mounting column 31. The mounting column 31 is used to mount the roller, and the connecting column 32 is used to be mounted to the connecting bracket 1.

[0041] The clamping block 2 includes a clamping portion 21 and an abutting portion 22, and the abutting portion 22 is fixedly connected to the clamping portion 21;

[0042] The connecting bracket 1 includes a bracket seat 11 and a bracket connecting ear 12, the bracket connecting ear 12 is fixedly connected to the bracket seat 11, a mounting groove 122 is provided on one side of the bracket connecting ear 12, and a clamping groove 121 is also provided on the bracket connecting ear 12, and a connecting groove connected to the mounting groove 122 is provided on one side of the clamping groove 121;

[0043] When the connecting column 32 is located in the installation groove 122 and the clamping portion 21 is located in the clamping groove 121 , the abutting portion 22 passes through the communicating groove to abut against the connecting column 32 , and a pressing force is exerted between the abutting portion 22 and the connecting column 32 .

[0044] The working principle is as follows: when disassembly is required, the clamping portion 21 is pushed out of the clamping groove 121 by external force. After the clamping portion 21 is separated from the clamping groove 121, the abutting force between the abutting portion 22 and the connecting column 32 also disappears. Therefore, the connecting column 32 of the rolling portion 3 can be pulled out from the side of the bracket connecting ear 12 along the clamping groove 121 with the mounting column 31 and the roller on the mounting column 31. Therefore, the rolling portion 3 can be taken out separately, and then the roller on the mounting column 31 that needs to be replaced and the bearing on the roller can be removed, and a new roller can be reinstalled.

[0045] After completion, the connecting column 32 can be installed into the installation groove 122 along the opening of the side installation groove 122 of the bracket connecting ear 12, and the clamping part 21 can be clamped into the clamping groove 121, so that the clamping force between the abutting part 22 and the connecting column 32 is restored to limit the connecting column 32.

[0046] This easily removable roller bracket structure is suitable for situations where the roller extends into the guide rail or guide groove from one side, causing the installation and disassembly work surface to be blocked. The rolling part 3 can be taken out separately from the side for replacement without removing the roller bracket and the carrier connected to it. The installation and replacement are simple, and the roller that can be replaced separately ensures the service life of the overall structure. Specific embodiment 2

[0048] See also Figure 4-5 As shown, in the specific embodiment 1, since the rolling part 3 is connected solely by the connecting column 32, it is not conducive to the thinness of the structure, or the thin structure is not stable enough. In order to improve the connection stability of the rolling part 3, this embodiment is based on the specific embodiment 1, and the rolling part 3 further includes a locking plate 33, and the locking plate 33 is fixedly connected to the end of the connecting column 32 away from the mounting column 31;

[0049] When the connecting column 32 is located in the installation groove 122 and the clamping portion 21 is located in the clamping groove 121 , the locking plate 33 includes a first working state and a second working state;

[0050] When the locking plate 33 is in the first working state, the projections of the locking plate 33 and the clamping block 2 on the same plane do not have overlapping parts;

[0051] When the locking plate 33 is in the second working state, the projections of the locking plate 33 and the clamping block 2 on the same plane have overlapping parts.

[0052] Therefore, when disassembly is required, the locking plate 33 can be used to rotate the entire rolling portion 3 through external force, so that the locking plate 33 is transformed from the second working state to the first working state, and the locking plate 33 provides clearance for the clamping block 2 to punch out;

[0053] When installation is required, after the clamping block 2 is installed in the clamping groove 121, the locking plate 33 is rotated so that the locking plate 33 is changed from the first working state to the second working state to prevent the clamping block 2 from detaching from the locking plate 33.

[0054] The end surface positioning function of the locking plate 33 makes the connection between the rolling portion 3 and the bracket connecting ear 12 more stable. In addition, the locking plate 33 can also take into account the limiting function of the clamping block 2. Specific embodiment three

[0056] See also Figure 4-5 As shown, on the basis of the specific embodiment 2, the diameter of the connecting column 32 is smaller than the mounting column 31. The size of the mounting column 31 is used to adapt to the standard bearing specifications to improve the versatility and interchangeability. The reduction in the size of the connecting column 32 can allow the end face of the mounting column 31 to form the end face positioning function on the other side, further improving the connection stability between the rolling portion 3 and the bracket connecting ear 12. In addition, the end face of the mounting column 31 can also take into account the limiting function on the other side of the clamping block 2, but the mounting column 31 cannot completely cover the clamping block 2.

[0057] When disassembly is required, since the mounting column 31 and the roller thereon have a certain size, there is also a certain space between the bracket connecting ear 12 and the roller. Therefore, when the clamping block 2 needs to be punched out, a hook-shaped tool can be used to punch out from the inside of the bracket connecting ear 12 to the outside. Specific embodiment 4

[0059] There are a plurality of bracket connecting ears 12 , and each of the plurality of bracket connecting ears 12 is equipped with a clamping block 2 and a rolling portion 3 .

[0060] A plurality of connecting brackets 1 can be used as a set and mounted to the same carrier using the bracket seat 11;

[0061] When used as a set, the carrier is usually larger in size and weight, and multiple connecting brackets 1 restrict each other. The roller that can be removed separately does not need to be removed together with the carrier and other connecting brackets 1, thereby reducing after-sales costs and improving efficiency.

[0062] It is particularly suitable for sliding pillars in side curtain carriages. The sliding pillars are large in size and heavy in weight, and need to be connected to hanging curtains. The structures restrict each other, while the rubber-coated bearings (rollers) are small in size and have little effect on the punching out of the clamping block 2. Therefore, there is no need to disassemble the side curtain cloth and the sliding pillar as a whole for repair and replacement, which greatly reduces the labor intensity and after-sales cost. This easily detachable roller bracket structure is also suitable for other products with the same structure.

[0063] The clamping portion 21 and the clamping slot 121 are in interference fit, which improves the connection stability of the clamping portion 21 .

[0064] In addition, a guide portion 13 is fixedly connected to the bracket seat 11, and the guide portion 13 is used to guide or connect the guide roller. The guide portion 13 is a prior art and will not be described in detail. Specific embodiment five

[0066] On the basis of the fourth specific embodiment, since the snap-in groove 121 and the snap-in portion 21 are interference fit, it is difficult to punch out. In order to facilitate the punching out of the snap-in block 2, this embodiment is based on the fourth specific embodiment. The bracket connecting ear 12 includes a first connecting ear 123 and a second connecting ear 124. The first connecting ear 123 is fixedly connected to the bracket seat 11. The first connecting ear 123 and the second connecting ear 124 are combined to form the snap-in groove 121. The second connecting ear 124 is fastened to the first connecting ear 123 by a fastener. The fastener can be loosened along the side of the bracket connecting ear 12, and then the interference fit of the snap-in groove 121 can be released by moving the second connecting ear 124, so as to facilitate punching out the snap-in block 2. The snap-in groove 121 formed by the combination of the second connecting ear 124 and the first connecting ear 123 should ensure that when the snap-in block 2 is installed in the snap-in groove 121, after the fastener is removed, the movement of the second connecting ear 124 is not restricted by the first connecting ear 123. Specific embodiment six

[0068] In the second specific embodiment, since the contact between the abutting portion 22 and the connecting column 32 is line contact, the rolling portion 3 is easy to slide. Therefore, based on the second specific embodiment, the clamping block 2 is further provided with a fixing hole 221, and the fixing hole 221 is connected with a fixing screw, which is used to fix the connecting column 32.

[0069] The connecting column 32 has a matching hole 321 at a position corresponding to the fixing hole 221.

[0070] When disassembly is required, before rotating the locking plate 33, it is necessary to loosen the set screw along the mounting groove 122 from the side of the bracket connecting ear 12 to release the limit of the set screw on the connecting column 32;

[0071] During installation, after rotating the locking plate 33, tighten the set screw and limit the rotation of the rolling part 3 to enhance the stability of the connection; Specific embodiment seven

[0073] In the second specific embodiment, since the contact mode between the abutting portion 22 and the connecting column 32 is line contact and the abutting force cannot be adjusted, the rolling portion 3 is easy to slide. Therefore, on the basis of the second specific embodiment, the connecting column 32 is further provided with a connecting hole 322, and the connecting hole 322 is detachably connected with an arc plate 323;

[0074] When disassembly is required, the locking plate 33 is rotated, the locking plate 33 drives the connecting column 32 to rotate, and the connecting column 32 drives the arc-shaped plate to rotate, so that the arc-shaped plate 323 leaves the abutting portion 22, reducing the force between the clamping block 2 and the rolling portion 3, making it easier to punch out the clamping block 2;

[0075] During installation, after punching in the clamping block 2, rotate the locking plate 33, the locking plate 33 drives the connecting column 32 to rotate, and the connecting column 32 drives the arc plate 323 to rotate to the abutment portion 22, and contacts with the abutment portion 22, and increases the abutment force through the arc plate 323. Not only can the abutment force be increased through the arc plate 323, but the size of the abutment force can also be adjusted through the angle of rotation.

[0076] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
