DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0049] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0050] The adjustable tire mounting seat provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0051] like Figures 1 to 10 As shown, an embodiment of the present application provides an adjustable tire mount, including a base 100, a positioning shaft 300 is rotatably provided on the base 100, an adjustment shaft 400 is slidably provided along the rotation axis on the end of the positioning shaft 300 away from the base 100, a positioning assembly 500 is fixedly provided on the end of the adjustment shaft 400 away from the positioning shaft 300, and an adjustment assembly 600 is detachably connected to the positioning assembly 500.

[0052] Among them, the positioning component 500 and the adjustment component 600 can respectively limit the two ends of the hub component 700, and an axial locking unit is provided between the positioning shaft 300 and the adjustment shaft 400, and the axial locking unit can limit multiple relative position points between the positioning shaft 300 and the adjustment shaft 400.

[0053] During actual use, the base 100 is initially fixed on a mounting base, and the adjusting assembly 600 is not installed on the positioning assembly 500. The axial position of the adjusting shaft 400 relative to the positioning shaft 300 is adjusted based on usage requirements, and the relative position between the positioning shaft 300 and the adjusting shaft 400 is fixed by an axial locking unit. After the hub component 700 is placed horizontally on the positioning assembly 500, the adjusting assembly 600 is installed on the positioning assembly 500, and the two ends of the hub component 700 are limited by the positioning assembly 500 and the adjusting assembly 600.

[0054] In an embodiment of the present application, the above-mentioned adjustable tire mounting seat is adopted, and the axial relative position between the positioning assembly 500 and the positioning shaft 300 is adjustable, and their relative positions can be fixed by an axial locking unit, so that the height of the positioning assembly 500 can be flexibly adjusted during the installation of the wheel hub component 700, thereby matching wheel hub components 700 of different specifications or different installation methods, thereby improving the overall applicability of the device.

[0055] In a preferred embodiment, Figure 1 , Figure 2 , Figure 4 , Figures 6 to 10 As shown, a plug hole 320 is provided at one end of the positioning shaft 300 away from the base 100 , and the adjustment shaft 400 is slidably disposed in the plug hole 320 and extends to the outside of the plug hole 320 at one end away from the base 100 .

[0056] The axial locking unit includes a locking hole 310 radially penetrating the insertion hole 320 on the positioning shaft 300 , and a plurality of positioning holes 410 radially penetrating the adjustment shaft 400 are arranged in a linear array along the axial direction of the adjustment shaft 400 .

[0057] The axial locking unit further includes a latch pin 210 that can penetrate the locking hole 310 and one of the positioning holes 410 , and a split pin 220 that can be inserted radially along the latch pin 210 at one end of the latch pin 210 that penetrates the locking hole 310 and the positioning hole 410 .

[0058] When the latch 210 is not installed, the adjusting shaft 400 can slide relative to the positioning shaft 300 to adjust the height of the positioning assembly 500. When the relative position between the adjusting shaft 400 and the positioning shaft 300 is adjusted to a predetermined position, the latch 210 is inserted into the lock hole 310 and passes through the positioning hole 410 at the corresponding position, and then the cotter pin 220 is inserted into the latch 210 to fix the relative position of the latch 210, the positioning shaft 300 and the adjusting shaft 400.

[0059] It is understandable that the fixing method of the latch 210 is not limited to the above-mentioned one. For example, the latch 210 can be fixed by bolts after being inserted, or an external thread can be directly provided on the latch 210, and an internal thread matching the external thread on the latch 210 can be provided on the lock hole 310 and / or the positioning hole 410. As long as the latch 210 can be fixed on the positioning shaft 300, it will not be elaborated here.

[0060] It can be understood that the setting form of the axial locking unit is not limited to the above-mentioned one. For example, a buckle can be set on the positioning shaft 300, and a plurality of slots that can be engaged with the buckle on the positioning shaft 300 can be set along an axial linear array on the adjusting shaft 400. When the adjusting shaft 400 moves to adjust the relative position with the positioning shaft 300, the relative position between the positioning shaft 300 and the adjusting shaft 400 is fixed by the cooperation of the buckle and the slot. As long as the positioning shaft 300 and the adjusting shaft 400 can be limited at multiple relative position points, it will not be elaborated here.

[0061] In a preferred embodiment, Figure 1 , Figure 2 , Figure 4 As shown, two positioning holes 410 are radially penetrated on the adjusting shaft 400 , and the two positioning holes 410 are arranged in a linear array along the axial direction of the adjusting shaft 400 .

[0062] like Fig. 9 As shown, when the hub member 700 is reversely installed on the positioning assembly 500, the latch 210 is plugged into the positioning hole 410 on the adjustment shaft 400 away from the positioning shaft 300. At this time, the relative distance between the positioning assembly 500 and the base 100 is shorter; Fig.10 As shown, when the hub component 700 is forwardly installed on the positioning assembly 500, the latch 210 is plugged into the positioning hole 410 on the adjusting shaft 400 close to the positioning shaft 300. At this time, the relative distance between the positioning assembly 500 and the base 100 is longer, thereby avoiding interference with the position of the hub component 700.

[0063] In the embodiment of the present application, the above-mentioned adjustable tire mounting seat is adopted, by setting two positioning holes 410 of different heights on the adjusting shaft 400, and when the adjusting shaft 400 and the positioning shaft 300 are matched, the relative position is restricted by the pin 210, and the positioning holes 410 in different positions cooperate with the pin 210 to obtain different heights of the positioning component 500, so that the positioning component 500 has two freely adjustable installation heights, and is suitable for the forward and reverse installation methods of the wheel hub component 700, and the applicability and practicality are greatly improved. At the same time, the matching structure is simple, the working stability is strong, and the maintenance cost is low.

[0064] In a preferred embodiment, Figure 7 , Figure 8 As shown, an elastic member 330 is provided between the adjusting shaft 400 and the bottom wall of the insertion hole 320 .

[0065] It is understandable that the elastic member 330 is mainly used to prevent the adjusting shaft 400 from directly colliding with the bottom wall of the hole 320 under the action of its own gravity after the pin 210 is pulled out, thereby alleviating the degree of wear of the positioning shaft 300 and the adjusting shaft 400 and ensuring the working stability of the device.

[0066] In a preferred embodiment, Figure 7 , Figure 8 As shown, the elastic member 330 is specifically configured as a tower spring, and the two ends of the tower spring can respectively abut against the bottom wall of the insertion hole 320 and the corresponding end of the adjustment shaft 400.

[0067] It is understandable that the configuration of the elastic member 330 is not limited to the above-mentioned one, as long as it can achieve collision buffering between the positioning shaft 300 and the adjustment shaft 400, which will not be elaborated herein.

[0068] In a preferred embodiment, Figures 1 to 3 , Fig. 9 , Fig.10 As shown, the adjustment assembly 600 includes an operating shaft 610 , a screw sleeve 640 threadedly connected to the operating shaft 610 , and a stopper 650 slidably disposed on the operating shaft 610 and located on a side of the screw sleeve 640 close to the positioning assembly 500 .

[0069] Among them, the end of the abutment 650 close to the positioning component 500 can abut the corresponding end of the hub component 700, and the end away from the positioning component 500 can abut against the screw sleeve 640, and the end of the control shaft 610 close to the base 100 can be detachably fixedly connected to the positioning component 500.

[0070] It can be understood that when the hub member 700 is placed on the side of the positioning assembly 500 away from the base 100, the control shaft 610 passes through the center hole of the hub member 700 and is fixedly connected to the positioning assembly 500. At this time, the abutment 650 is located on the side of the hub member 700 away from the positioning assembly 500. The operator can adjust its relative position with the hub member 700 by rotating the screw sleeve 640, thereby pushing the abutment 650 to move to the side of the hub member 700 through the screw sleeve 640 until it abuts against the hub member 700. Under the abutting force of the positioning assembly 500 and the abutment 650, the hub member 700 can be limited.

[0071] It is understandable that the abutment 650 can also be directly fixedly disposed on the end of the screw sleeve 640 close to the positioning assembly 500 . However, in this case, the rotation of the screw sleeve 640 will drive the abutment 650 to rotate, which may cause wear between the abutment 650 and the hub 700 .

[0072] In a preferred embodiment, Figures 1 to 3 , Fig. 9 , Fig.10 As shown, the abutment 650 is in a conical structure, and the end with a smaller radius faces the positioning assembly 500 .

[0073] It is understandable that when the abutment 650 abuts against the hub member 700 , the abutment 650 can abut against the inner wall of the center hole of the hub member 700 through its own conical structure, thereby achieving automatic alignment of the center axis of the abutment 650 with the center axis of the hub member 700 .

[0074] In a preferred embodiment, Figures 1 to 3 , Fig. 9 , Fig.10 As shown, the adjustment assembly 600 further includes a handle member 620 fixedly disposed on an end of the control shaft 610 away from the positioning assembly 500 .

[0075] In a preferred embodiment, Figures 1 to 3 , Fig. 9 , Fig.10 As shown, the adjustment assembly 600 further includes two handles 630 symmetrically arranged on the outer circumferential surface of the screw sleeve 640 along the central axis of the screw sleeve 640 and elastically hinged to the screw sleeve 640 .

[0076] It is understandable that the operator can conveniently control the rotation of the screw sleeve 640 by holding the handle 630 .

[0077] In a preferred embodiment, Figures 2 to 6 As shown, a clamping portion 660 is fixedly provided at one end of the control shaft 610 close to the base 100, and two locking grooves 670 are symmetrically provided on the clamping portion 660 about the central axis of the control shaft 610. A connecting hole 420 is provided at one end of the adjustment shaft 400 away from the positioning shaft 300, and two first locking pins 430 symmetrically arranged along the central axis of the adjustment shaft 400 and parallel to each other are fixedly provided on the inner wall of the connecting hole 420, and a second locking pin 440 is also fixedly provided on the side of the first locking pin 430 close to the positioning shaft 300.

[0078] When the clamping portion 660 and the adjusting shaft 400 are at a first relative angle, the clamping portion 660 can pass through the two first locking pins 430 and abut against the second locking pin 440; when the clamping portion 660 and the adjusting shaft 400 are at a second relative angle, the end of the clamping portion 660 close to the base 100 can abut against the second locking pin 440, and the two first locking pins 430 are respectively embedded in the two locking grooves 670 to realize the axial limitation of the clamping portion 660 on the adjusting shaft 400.

[0079] The first relative angle is specifically that the extending direction of the locking groove 670 is perpendicular to the axial direction of the first locking pin 430 , and the second relative angle is specifically that the extending direction of the locking groove 670 is parallel to the axial direction of the first locking pin 430 .

[0080] When the adjusting assembly 600 is installed on the positioning assembly 500, the clamping portion 660 passes through the gap between the two first locking pins 430 until it abuts against the second locking pin 440. At this time, the clamping portion 660 is located between the first locking pin 430 and the second locking pin 440. When the operator rotates the control shaft 610, the clamping portion 660 rotates synchronously, and the two first locking pins 430 respectively enter the two locking grooves 670, that is, the outer surfaces of the first locking pins 430 on both sides along the axial direction of the adjusting shaft 400 abut against the inner walls of the corresponding sides of the locking grooves 670, and the axial displacement of the clamping portion 660 relative to the adjusting shaft 400 is restricted. When the two first locking pins 430 are completely embedded in the two locking grooves 670, the installation of the adjusting assembly 600 on the positioning assembly 500 is completed.

[0081] It is understandable that the detachable connection form of the adjustment component 600 is not limited to the above-mentioned one. For example, a snap-fit ​​structure can be set between the adjustment component 600 and the adjustment shaft 400 (or the positioning component 500), or a bolt fixing structure can be set between the adjustment component 600 and the adjustment shaft 400 (or the positioning component 500). As long as the relative position between the control shaft 610 and the positioning component 500 can be fixed, it will not be elaborated here.

[0082] In a preferred embodiment, Figure 1 , Figure 2 , Figure 4 As shown, the positioning assembly 500 includes a positioning plate 510 fixedly disposed at one end of the adjusting shaft 400 away from the positioning shaft 300 , and a stop plate 520 fixedly disposed at one end of the positioning plate 510 away from the adjusting shaft 400 .

[0083] A fixing pin 511 is fixedly provided on the positioning plate 510 , a rotating plate 512 is rotatably provided on the fixing pin 511 , and a positioning pin 513 is fixedly provided on the rotating plate 512 .

[0084] A clearance groove 521 is formed on the contact plate 520 along its axial direction. The positioning pin 513 is slidably disposed in the clearance groove 521 and extends away from one end of the rotating plate 512 to a side of the contact plate 520 away from the positioning plate 510 .

[0085] It can be understood that when the hub component 700 is placed on the end of the abutment 520 away from the positioning plate 510, the rotating plate 512 can swing to adjust the position of the positioning pin 513, so that the positioning pin 513 is plugged into the through hole on the hub component 700, and then cooperates with the abutment 650 on the adjustment assembly 600 to realize automatic centering of the hub component 700.

[0086] In a preferred embodiment, Figure 1 , Figure 2 , Figures 7 to 10As shown, the base 100 includes a mounting seat 110 fixedly disposed on a mounting base, a sleeve member 130 is fixedly disposed on the mounting seat 110 , and a positioning shaft 300 is rotatably disposed on the sleeve member 130 .

[0087] The end of the positioning shaft 300 away from the adjusting shaft 400 passes through the sleeve member 130 and the mounting seat 110 and is connected to the external driving assembly.

[0088] In a preferred embodiment, Figure 7 , Figure 8 As shown, a receiving cavity 131 is formed through the sleeve member 130 along the axial direction, and a through groove 111 is formed through the mounting seat 110 along the axial direction.

[0089] The positioning shaft 300 is rotatably disposed in the accommodating cavity 131 and one end away from the adjusting shaft 400 passes through the through slot 111 .

[0090] In a preferred embodiment, Figure 7 , Figure 8 As shown, a bushing 140 is disposed between the inner wall of the accommodating cavity 131 and the outer circumferential surface of the positioning shaft 300 .

[0091] In a preferred embodiment, Figure 7 , Figure 8 As shown, two bushings 140 are disposed between the inner wall of the accommodating cavity 131 and the outer circumferential surface of the positioning shaft 300 , and the two bushings 140 are respectively located at two ends of the sleeve member 130 .

[0092] In a preferred embodiment, Figure 7 , Figure 8 As shown, a first washer 120 is sandwiched between the positioning shaft 300 and one end of the sleeve member 130 close to the mounting seat 110 .

[0093] In a preferred embodiment, Figure 7 , Figure 8 As shown, a retaining spring 160 is embedded on the outer circumferential surface of the positioning shaft 300 , and a second washer 150 is sandwiched between the retaining spring 160 and the end of the sleeve member 130 away from the mounting seat 110 .
