[0002] Casters are a common mechanical accessory installed at the bottom of an appliance to make the appliance move conveniently and flexibly. They are widely used in scaffolding, shelves, instruments, mechanical equipment, furniture and other fields. At present, the wheels of casters on the market are generally riveted to the fork through a transverse axis or the two are connected by bolts. When such casters are used on the chairs of barbershops, the hair cut on the ground can easily get entangled on the wheels and the connection between the wheels and the fork; because the casters with the above structure cannot be quickly disassembled and assembled during use, that is, the wheels cannot be quickly separated and assembled from the fork.
[0003] To this end, we provide a quick-release caster with a buffer to solve the above-mentioned problems. Utility Model Content

[0006] The utility model is further configured such that the buffer member includes a spring and a rod, wherein the top of the rod is fixed to the lower side of the support plate, the bottom of the rod is passed through the middle position of the mounting frame, and a nut structure is fixed to the bottom of the rod, the spring is sleeved on the outside of the rod, and the spring is located between the mounting frame and the support plate.
[0007] The utility model is further configured that the mounting frame is an integrally formed structure, and the ends of the mounting frame are horizontally connected.
[0008] The utility model is further configured that a plurality of elastic convex balls are linearly arranged, and the elastic convex balls are in contact with and fit the positioning piece.
[0009] The utility model is further configured that the wheel body includes a middle receiving member, a wheel hub fixed to the outer ring of the middle receiving member, and a tire sleeved on the outer ring of the wheel hub.
[0010] The utility model is further configured that a mounting groove is provided at an edge of the support plate, the support plate is fixed to an external mounting surface, and the buffer pad is clamped between the support plate and the external mounting surface.
[0011] The utility model has the following beneficial effects:
[0012] The utility model realizes double buffering of the caster body by arranging the buffer pad and the buffer member, effectively improving the buffering effect of the caster body. At the same time, an elastic convex ball structure is added to the end of the shaft rod to replace the traditional nut fixing structure, making it convenient to load and unload.
[0013] The elastic convex ball is movably arranged in the shaft rod, and a notch is arranged on the circumference of the shaft rod for the movement of the elastic convex ball. The elastic structure built in the notch pushes the elastic convex ball so that it is exposed outside the shaft rod. At the same time, under the limiting effect of the notch, the elastic convex ball cannot be separated from the shaft rod, and the elastic convex ball is pressed to be stored inside the shaft rod.

[0022] Example
[0023] See also Figure 1-3 The utility model is a quick-release caster with buffering, comprising a caster body 1; the caster body 1 comprises a bracket 11, a support plate 12 fixed to the top of the bracket 11, a buffer pad 13 fixed to the middle position of the upper side of the support plate 12, a mounting frame 14 connected to the lower end of the bracket 11, a wheel body 18 movably arranged at the end of the mounting frame 14 via a shaft 17, an elastic convex ball 111 elastically arranged at the end of the shaft 17, a positioning member 19 sleeved on the end of the shaft 17, a stop member 110 installed at the end of the positioning member 19, and a buffer member arranged at the middle position of the mounting frame 14.
[0024] Specifically, in the quick-release caster with buffering proposed in the present application, a buffer pad 13 and a buffering member are provided to realize double buffering of the caster body 1, thereby effectively improving the buffering effect of the caster body 1. At the same time, an elastic convex ball 111 structure is added to the end of the shaft 17 to replace the traditional nut fixing structure, so that the caster body 1 is easy to load and unload.
[0025] The elastic convex ball 111 is movably arranged in the shaft rod 17. A notch is arranged on the circumference of the shaft rod 17 for the movement of the elastic convex ball 111. The elastic structure built in the notch pushes the elastic convex ball 111 so that it is exposed outside the shaft rod 17. At the same time, under the limiting effect of the notch, the elastic convex ball 111 cannot be separated from the shaft rod 17, and the elastic convex ball 111 is pressed to be stored inside the shaft rod 17.
[0026] Furthermore, the buffer member includes a spring 15 and a rod 16, wherein the top of the rod 16 is fixed to the lower side of the support plate 12, the bottom of the rod 16 is passed through the middle position of the mounting frame 14, and a nut structure is fixed to the bottom of the rod 16, the spring 15 is sleeved on the outside of the rod 16, and the spring 15 is located between the mounting frame 14 and the support plate 12, the mounting frame 14 is an integrally formed structure, and the ends of the mounting frame 14 are horizontally connected.
[0027] Specifically, the buffer is used for buffering protection of the caster body 1. When the caster body 1 is subjected to pressure, the support plate 12 tends to approach the mounting frame 14. During this process, the support plate 12 drives the rod 16 to move downward, and the spring 15 is compressed under the compression of the protrusion at the end of the rod 16 to achieve buffering of external pressure. The bottom of the rod 16 is movably arranged relative to the mounting frame 14. At the same time, under the limiting action of the nut structure, the rod 16 cannot be separated from the mounting frame 14.
[0028] The support plate 12 is provided with a mounting groove at its edge, the support plate 12 is fixed to the external mounting surface, and the buffer pad 13 is clamped between the support plate 12 and the external mounting surface.
[0029] Specifically, the support plate 12 is generally fixed to the outer mounting surface via a bolt structure. After installation and fixation, the buffer pad 13 is clamped and installed between the support plate 12 and the outer mounting surface, and also plays a partial buffering role.
[0030] Furthermore, a plurality of elastic convex balls 111 are linearly arranged, and the elastic convex balls 111 are in contact with and fit the positioning member 19 .
[0031] Specifically, the elastic convex balls 111 are provided in plurality, so that the elastic convex balls 111 have multiple fixing points, which facilitates the fixing of wheels 18 of different widths.
[0032] Furthermore, the wheel body 18 includes a middle receiving member 1803 , a wheel hub 1802 fixed to the outer ring of the middle receiving member 1803 , and a tire 1801 sleeved on the outer ring of the wheel hub 1802 .
[0033] Specifically, the middle receiving part 1803 in the wheel body 18 is connected to the shaft 17, the wheel hub 1802 is fixed to the outside of the middle receiving part 1803, and the tire 1801 is embedded in the recessed area in the middle of the wheel hub 1802. The three are combined to form the overall structure of the wheel body 18.
