the leather cushion comprises an upper cushion and a lower cushion, wherein the middle of the upper cushion is hollowed out, an annular groove is formed in the lower cushion, a plurality of spiral springs are arranged in the groove at equal intervals, the bottoms of the spiral springs are connected with the groove, the upper end of each spiral spring is provided with an annular separation blocking piece which can be clamped in the groove, a plurality of support columns are arranged above the separation blocking piece at equal intervals, the upper ends of the support columns are fixedly connected with balls, and the upper cushion is provided with an annular sliding groove which can be buckled on the balls.

Preferably, a plurality of slots are arranged on the two side edges of the groove at equal intervals, and the blocking piece is provided with a convex block which can be clamped in the slot.

Preferably, the number of the card slots is three or more, and the number of the bumps is equal to the number of the card slots.

Preferably, the width of the baffle plate is consistent with the width of the groove.

Preferably, the shape of the slot and the bump is a cube.

Preferably, the surface of the upper cushion is sleeved with a leather sleeve.

Due to the adoption of the technical scheme, compare with prior art, the utility model discloses following beneficial effect has:

the spiral spring is arranged between the lower seat cushion and the upper seat cushion and can play a certain shockproof and buffering role. The middle of the upper layer seat cushion is hollowed, the sliding groove at the bottom of the upper layer seat cushion is buckled on the rolling balls, the upper layer seat cushion can rotate left and right relative to the rolling balls, and the position of a body of a hemorrhoid patient can be conveniently and comfortably adjusted when the hemorrhoid patient sits on the leather cushion.

Detailed Description

The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiment of the present invention, all other embodiments that a person skilled in the art can obtain without creative work all belong to the protection scope of the present invention.

As shown in fig. 1, the leather pad comprises an upper cushion 1 and a lower cushion 2 with hollow-out middle parts, wherein an annular groove 3 is arranged in the lower cushion 2, a plurality of spiral springs 4 are arranged in the groove 3 at equal intervals, the lower ends of the spiral springs 4 are connected with the groove 3, the upper ends of the spiral springs are provided with annular separation blades 5 which can be clamped in the groove 3, a plurality of support columns 6 are arranged on the separation blades 5 at equal intervals, the upper ends of the support columns 6 are fixedly connected with balls 7, the upper cushion 1 is provided with an annular chute 8, and the chute 8 is buckled on the balls 7.

The lower end of the spiral spring 4 is fixedly connected with the bottom of the groove 3, and the height of the spiral spring is slightly smaller than that of the groove 3. As a preferred solution, the helical spring 4 may be made of stainless steel material, with a diameter slightly smaller than the width of the groove 3. Thus, the spiral spring 4 can play a good shockproof buffer role.

The baffle 5 is arranged in a ring shape, and the width of the baffle is matched with that of the groove 3. Generally, the width of the baffle 5 is equal to or slightly less than the width of the recess 3. The upper end of spiral spring 4 is connected in the bottom that separates separation blade 5, separates separation blade 5 joint in recess 3, when the user sits in upper seatpad 1, separates separation blade 5 downstream, can force spiral spring 4 to produce an ascending elasticity, so can alleviate the impact force that the leather pad received, brings comfortable impression for the haemorrhoids patient.

In order to enable the separation blocking piece 5 to be clamped in the groove 3 better, a plurality of clamping grooves 9 are formed in the edges of the two sides of the groove 3 at equal intervals, and then convex blocks 10 matched with the clamping grooves 9 in size are installed on the edges of the two sides of the separation blocking piece 5. The shape of the slots 9 and the bumps 10 is preferably a cube or a cuboid, and the number of the two is equal, and may be three or more. During installation, the slot 9 can be as high as the groove 3, and the height of the coil spring 4 is less than that of the groove 3. The height of the coil spring 4 in the natural state, added to the height of the projection 10, is equal to the height of the slot 9, preferably smaller than the height of the slot 9. Therefore, when the bump 10 is clamped into the slot 9, the blocking piece 5 can be stably and firmly clamped into the groove 3. If a user needs to replace and maintain the spiral spring 4 or the separation blade 5, the separation blade 5 can be easily and conveniently detached from the groove 3 through the supporting column 6.

In addition, as a further improvement, a leather sheath 11 can be pre-installed on the surface of the upper cushion 1, or a layer of compressed sponge which can play a role in buffering and warming is additionally arranged between the leather sheath 11 and the upper cushion 1 when the leather sheath 11 is installed.

As a modification, the balls 7 in the present embodiment may be replaced with ball bearings. The inner ring of the ball bearing is connected to the support column 6, and the outer ring of the ball bearing is equal in width to the sliding groove 8. The sliding groove 8 is buckled on the ball bearing, when the upper layer cushion rotates, the ball bearing can roll simultaneously, and the service life of the leather cushion can be prolonged.

The above all be the utility model discloses a preferred embodiment, the utility model discloses a protection scope does not confine above-mentioned embodiment to, the all belong to the utility model discloses other technical scheme under the thinking all belong to the utility model discloses a protection scope. It should be noted that various modifications and decorations made by those skilled in the art without departing from the principle of the present invention should be considered as the protection scope of the present invention.
