[0047] Figure 1 A structure schematic diagram of a golf sand-trap simulation practice board provided by an embodiment of the present application; wherein the heightening structure 4 of the golf sand-trap simulation practice board is in a storage position. Figure 2 A structure schematic diagram of a golf sand-trap simulation practice board provided by another embodiment of the present application; wherein the heightening structure 4 of the golf sand-trap simulation practice board is in a supporting position.

[0048] As Figures 1-8 shown, the embodiment of the application provides a sand-trap-simulating golf practice board, which mainly comprises a bottom plate 1, a first pile layer 2, a second pile layer 3 and a heightening structure 4. The first pile layer 2 and the second pile layer 3 are both protruded from one side of the bottom plate 1, and there is a height difference between the first pile layer 2 and the second pile layer 3. The first pile layer 2 and the second pile layer 3 are arranged alternately. The heightening structure 4 is connected with the bottom plate 1, so that the bottom plate 1 is inclined to form a slope.

[0049] In the embodiment, the bottom plate 1 can be a rectangular plate, and the size of the bottom plate 1 can be designed according to actual conditions, which is not set in the application. Optionally, the material of the bottom plate 1 includes plastic.

[0050] In some embodiments, the bottom plate 1 is slightly arc-shaped upward, so that the bottom plate 1 has better grip and stronger stability.

[0051] The bottom plate 1 is horizontally arranged. The first pile layer 2 and the second pile layer 3 are protruded upward from the bottom plate 1. The first pile layer 2 and the second pile layer 3 both comprise a bundle-shaped pile structure composed of a plurality of single "piles". The material of the "piles" can be nylon yarn or polypropylene yarn, so that the pile layer has certain resistance to bending, support, elasticity and other characteristics. The density of the pile structure can also be adjusted appropriately to improve the authenticity of the simulated sand trap. Optionally, the first pile layer 2 is higher than the second pile layer 3. Optionally, the first pile layer 2 is lower than the second pile layer 3.

[0052] It should be noted that the embodiments of the application are exemplified with the height of the first pile layer 2 being higher than the height of the second pile layer 3.

[0053] In some embodiments, there can also be a height difference between the pile structures of the same pile layer to improve the authenticity of the simulation. The height difference between the first pile layer 2 and the second pile layer 3 can be a fixed value or different values, which can be designed according to actual conditions, which is not set in the application.

[0054] The heightening structure 4 is arranged at the bottom of the bottom plate 1, which can be close to one end of the bottom plate 1, and is used to lift the bottom plate 1. The two ends of the bottom plate 1 form a height difference, so that the bottom plate 1 is inclined to form a slope.

[0055] Through the embodiments provided by the application, the first pile layer and the second pile layer with different heights and arranged alternately are fixed to the bottom plate 1. The golf ball sinks into the pile layer with a higher height, and the pile layer with a lower height supports the golf ball, so as to simulate the depth of the golf ball sinking into the sand trap. The user can use the heightening structure 4 to realize that the bottom plate 1 has a slope according to his own needs, so as to perform a hitting practice.

[0056] As Figure 4 and 7As an optional embodiment, the golf sand-trap practice board further comprises anti-skid protrusions 5 protruding from the bottom plate 1 on the side opposite to the first and second layers of bristles 2 and 3.

[0057] Based on the foregoing embodiment, in this embodiment, the anti-skid protrusions 5 protrude downward from the bottom plate 1 to increase the friction with the ground, prevent the bottom plate 1 from sliding, ensure the stability of the bottom plate 1 during use, and avoid the sliding of the bottom plate 1 to reduce the user experience.

[0058] In some embodiments, the anti-skid protrusions 5 have a conical shape with a small end at the bottom.

[0059] In some embodiments, the bottom plate 1 is provided with a plurality of anti-skid protrusions 5 arranged in an array.

[0060] As shown in Figure 4 and 7 As an optional embodiment, the bottom plate 1 is formed with grooves 11 on the side opposite to the first and second layers of bristles 2 and 3, a part of the anti-skid protrusions 5 are embedded in the grooves 11, and the other part of the anti-skid protrusions 5 protrude from the bottom plate 1; the bottom plate 1 is provided with through-hole structures 12 along the thickness direction and in communication with the grooves 11, the bristle structures included in the first layer of bristles 2 and / or the bristle structures included in the second layer of bristles 3 are inserted into the through-hole structures 12 and connected with the anti-skid protrusions 5.

[0061] Based on the foregoing embodiment, in this embodiment, the bottom plate 1 is provided with upwardly recessed grooves 11 at the bottom, and the openings of the grooves 11 face downward. The grooves 11 are adapted to the anti-skid protrusions 5. The bottom plate 1 is provided with through-hole structures 12 along the vertical direction, and the grooves 11 are located below the through-hole structures 12.

[0062] The bristle structures included in the first layer of bristles 2 and / or the bristle structures included in the second layer of bristles 3 are inserted into the through-hole structures 12 through the top ends of the through-hole structures 12. A part of the anti-skid protrusions 5 are embedded in the grooves 11 to support and connect with the first and / or second layers of bristles 2 and 3. The anti-skid protrusions 5 are fixed by gluing and adhered to the bristle structures inserted into the through-hole structures 12, so that the bristle structures are fixed more firmly and are less likely to fall off, improving the durability of use.

[0063] In some embodiments, the bottom plate 1 is provided with a plurality of through-hole structures 12 arranged in an array.

[0064] In some embodiments, the through-hole structures 12 include circular holes and / or long strip-shaped holes; if both the circular holes and the long strip-shaped holes exist, the circular holes and the long strip-shaped holes are arranged alternately.

[0065] As shown in Figure 5 and 7As shown, in one optional embodiment, the base plate 1 has a countersunk hole structure 13 along the thickness direction, and the hair structure included in the first hair layer 2 and / or the hair structure included in the second hair layer 3 is inserted into the countersunk hole structure 13.

[0066] Based on the aforementioned embodiments, in this embodiment, the opening of the countersunk hole structure 13 is set upward. After the bottom end of the rough structure is coated with glue, it is inserted into the countersunk hole structure 13 through the top end of the countersunk hole structure 13 to achieve fixation.

[0067] In some embodiments, the higher-height layer of the first layer 2 and the second layer 3 is fixed by a countersunk hole structure 13; the lower-height layer of the first layer 2 and the second layer 3 is fixed by a through hole structure 12. This is because the lower-height layer, as the structure supporting the golf ball, is subjected to greater stress and wear, and therefore requires a more secure fixing method to improve durability and prevent shedding.

[0068] like Figure 3 As shown, in one optional implementation, the first layer 2 includes a plurality of first hair structures 21 arranged in strips and side by side; the second layer 3 includes a plurality of second hair structures 31 arranged in strips and side by side; the first hair structures 21 and the second hair structures 31 extend in the same direction and are alternately arranged in a direction perpendicular to the extension direction.

[0069] Based on the aforementioned embodiments, in this embodiment, the base plate 1 is a rectangular plate, and the first textured structure 21 and the second textured structure 31 both extend along the length direction of the base plate 1. The first textured structure 21 and the second textured structure 31 are arranged to intersect along the width direction of the base plate 1. For example, along the width direction of the base plate 1, the first textured structure 21 is followed by the second textured structure 31, and the second textured structure 31 is followed by the first textured structure 21, and so on, repeating alternately to achieve alternating heights and uniform distribution of the first textured layer 2 and the second textured layer 3.

[0070] The raised structure 4 has multiple implementation methods, which will be described in detail below.

[0071] like Figures 1-4 As shown in Figures 7 and 8, in one optional embodiment, the raised structure 4 includes a first support, which is rotatably connected to the base plate 1 and disposed at the edge of the base plate 1. The first support rotates between a retracted position and a supported position. The first support includes a leg, which includes a first plate 41 and a second plate 42 connected at an angle. The first plate 41 is rotatably connected to the base plate 1. When the leg is in the retracted position, the first plate 41 is retracted to the side of the base plate 1, and the second plate 42 is retracted to the bottom of the base plate 1. When the leg is in the supported position, a portion of the first plate 41 and at least a portion of the second plate 42 are located at the bottom of the base plate 1 for a support connection with the base plate 1.

[0072] Based on the foregoing embodiments, in this embodiment, when the first support is in the storage position, the first support is not in a supporting relationship with the bottom plate 1, and the bottom plate 1 can be placed at will. If the bottom plate 1 is placed on a horizontal surface, the bottom plate 1 has no slope; if the bottom plate 1 is placed on an inclined surface, the bottom plate 1 forms a slope. When the first support is in the supporting position, the first support and the bottom plate 1 are in a supporting relationship, so that the bottom plate 1 has a slope. For example, the bottom plate 1 is placed on a horizontal surface, and the first support supports the bottom plate 1, so that one end of the bottom plate 1 is higher to form a slope; for another example, the bottom plate 1 is placed on an inclined surface, and the bottom plate 1 does not reach the slope desired by the user or is horizontal, and the first support can be used to support and adjust the bottom plate 1.

[0073] As shown in Figure 8 , Figure 8 a structure diagram of a high structure 4 in a golf sand trap practice board provided by an embodiment of the present application; wherein, Figure 8 The position identified by the dashed line in the figure is the joint of the first segment 411 and the second segment 412.

[0074] The first support includes corresponding supporting legs, that is, two symmetrical supporting legs are arranged on opposite sides of the bottom plate 1, or two symmetrical supporting legs are arranged on the same side of the bottom plate 1.

[0075] In some embodiments, the first plate 41 and the second plate 42 are connected perpendicularly; the first plate 41 includes a first segment 411 and a second segment 412 connected to each other, the side edge of the first segment 411 is connected to the second plate 42, and the second segment 412 is not connected to the second plate 42 to form a clearance space, so as to avoid interference between the second plate 42 and the bottom plate 1 in the supporting leg rotation stage, so that the supporting leg can be rotated to the designed position; optionally, the first segment 411 and the second segment 412 are integrally formed.

[0076] The second section 412 is provided with a first hole 413 in the thickness direction, and the side edge of the bottom plate 1 is provided with a second hole 14 matched with the first hole 413. The screw passes through the first hole 413 and the second hole 14 to realize the rotational connection of the support leg and the bottom plate 1. The support leg can rotate clockwise and counterclockwise relative to the bottom plate 1 to adjust the relative position of the support leg and the bottom plate 1, that is, to move between the storage position and the support position. When the support leg is in the support position, the bottom of the bottom plate 1 forms a protruding structure, so that one end of the bottom plate 1 is high and the other end is low. Among them, the bottom end of the first plate 41 contacts the ground to form a support, and the top end of the second plate 42 contacts the bottom plate 1 to form a support. In a specific embodiment, the first support includes three sub-supports with different support heights, wherein the support heights are in order from low to high as the first sub-support, the second sub-support and the third sub-support. One first sub-support, one second sub-support and one third sub-support form a group of support legs, and two groups of support legs are arranged on the same side edge of the bottom plate 1. The rotation direction of the two groups of support legs from the storage position to the support position is opposite, that is, the rotation direction of one group from the storage position to the support position is clockwise, and the rotation direction of the other group from the storage position to the support position is counterclockwise.

[0077] Figure 9 A structure schematic diagram of a plurality of sub-supports with different support heights in a golf sand trap practice board provided by an embodiment of the application and all in the storage position.

[0078] As shown in Figure 9 , the lengths of the plurality of sub-supports with different support heights are different, and the longer the length of the sub-support, the higher the support height, that is, the first plate 41 of the sub-support with the lowest support height has the longest length, and the first plate 41 of the sub-support with the highest support height has the shortest length.

[0079] Figure 10 A structure schematic diagram of a plurality of sub-supports with different support heights in a golf sand trap practice board provided by an embodiment of the application, wherein the first sub-support is in the support position, and the second sub-support and the third sub-support are both in the storage position.

[0080] Figure 11 A structure schematic diagram of a plurality of sub-supports with different support heights in a golf sand trap practice board provided by an embodiment of the application, wherein the first sub-support and the second sub-support are both in the support position, and the third sub-support is in the storage position.

[0081] Figure 12 A structure schematic diagram of a plurality of sub-supports with different support heights in a golf sand trap practice board provided by an embodiment of the application, wherein the first sub-support, the second sub-support and the third sub-support are all in the support position.

[0082] As shown in Figure 10As shown, only when the first sub-support leg with the lowest support height is in the support position is the first plate 41 of the first sub-support leg connected to the second plate 42, and the second plate 42 of the first sub-support leg connected to the base plate 1. In this state, the slope of the base plate 1 is the gentlest.

[0083] like Figure 11 As shown, when the second sub-support leg with a higher support height is in the support position, the first sub-support leg is also in the support position. The second plate 42 of the first sub-support leg is connected to the base plate 1, and the first and second sub-support legs are connected together. In this state, the slope of the base plate 1 is moderate.

[0084] like Figure 12 As shown, when the third sub-support leg, which has the highest support height, is in the support position, the first and second sub-support legs are also in the support position. The second plate 42 of the first sub-support leg is connected to the base plate 1, and the first, second, and third sub-support legs are connected together. In this state, the slope of the base plate 1 is the steepest.

[0085] like Figures 9-12 As shown, in one optional implementation, the support leg includes multiple sub-support legs with different support heights. When all the sub-support legs are in the retracted position, the first plates 41 of the multiple sub-support legs are stacked, with the first plate 41 of the sub-support leg with the lower support height located outside the first plate 41 of the sub-support leg with the higher support height. The second plates 42 of all the sub-support legs are retracted into the bottom of the base plate 1. When only the first sub-support leg with the lowest support height is in the supported position, the first plate 41 of the first sub-support leg is supported and connected to the second plate 42, and the second plate 42 of the first sub-support leg is supported and connected to the base plate 1. When the second sub-support leg with the higher support height is in the supported position, all the sub-support legs with the lower support height are in the supported position and form a supporting relationship relative to the second sub-support leg, and the second plate 42 of the first sub-support leg is supported and connected to the base plate 1.

[0086] Based on the aforementioned embodiments, in this embodiment, multiple sub-supports with different support heights refer to the support feet that, when in the support position, cause the base plate 1 to form support feet with different tilt angles. This allows for more flexible adjustment of the slope to meet the user's needs for different slopes.

[0087] The lengths of the multiple sub-legs with different support heights are different. The higher the support height, the longer the sub-leg. That is, the first plate 41 of the sub-leg with the lowest support height is the longest, and the first plate 41 of the sub-leg with the highest support height is the shortest.

[0088] The bottom plate 1 is horizontally arranged, and the first plates 41 of all the sub-stands are in abutment when all the sub-stands are in the storage position. The first plate 41 of the sub-stand with the lowest support height is in abutment with the outer side of the first plate 41 of the sub-stand with the highest support height, i.e., the first plate 41 of the sub-stand with the lowest support height is located at the outermost side, and the first plate 41 of the sub-stand with the highest support height is located at the innermost side. This arrangement can realize the arrangement of multiple sub-stands with less space and facilitate the movement of any sub-stand.

[0089] Based on the foregoing embodiment, only the first sub-stand with the lowest support height is in the support position, the first plate 41 of the first sub-stand is in support connection with the second plate 42, and the second plate 42 of the first sub-stand is in support connection with the bottom plate 1. In this state, the slope of the bottom plate 1 is the gentlest.

[0090] When the second sub-stand with the higher support height is in the support position, the first sub-stand is in the support position, the second plate 42 of the first sub-stand is in support connection with the bottom plate 1, and the first sub-stand and the second sub-stand are in support connection. In this state, the slope of the bottom plate 1 is moderate.

[0091] When the third sub-stand with the highest support height is in the support position, the first sub-stand and the second sub-stand are in the support position, the second plate 42 of the first sub-stand is in support connection with the bottom plate 1, and the first sub-stand, the second sub-stand, and the third sub-stand are in support connection. In this state, the slope of the bottom plate 1 is the steepest.

[0092] As an optional embodiment, the heightening structure 4 comprises a second support which is detachably connected with the bottom plate 1; the second support has a first slot; the bottom plate 1 is inserted into the second support through the first slot, and the second support is arranged on the side of the bottom plate 1 opposite to the first and second pile layers 2 and 3, so that the bottom plate 1 is inclined to form a slope.

[0093] Based on the foregoing embodiment, in this embodiment, the second support is a "U"-shaped structure with low middle and high two ends, i.e., the first slot. The bottom plate 1 is inserted into the second support through the first slot, so that one end of the bottom plate 1 is high and the other end is low. When the slope is not needed, the second support is not used. Optionally, the material of the second support comprises silica gel.

[0094] As an optional embodiment, the heightening structure 4 comprises a third support which is detachably connected with the bottom plate 1; the side of the bottom plate 1 opposite to the first and second pile layers 2 and 3 and close to the edge of the bottom plate 1 is formed with a second slot; a part of the third support is inserted into the second slot, and the other part of the third support protrudes from the bottom plate 1, so that the bottom plate 1 is inclined to form a slope.

[0095] Based on the foregoing embodiments, in this embodiment, the bottom of the bottom plate 1 has a concave portion, i.e., a second slot, which is concave upward. The third support can be block-shaped, strip-shaped, or of a special shape. The third support is adapted to the concave portion. Part of the third support is embedded in the second slot, and another part of the third support protrudes from the bottom plate 1. The bottom of the bottom plate 1 is formed with a protruding structure, so that one end of the bottom plate 1 is higher than the other end. When the slope is not needed, the third support is not used. Optionally, the material of the third support includes silica gel.

[0096] As shown in Figures 13-18 , as an optional embodiment, the cushioning structure 4 includes a fourth support which is column-shaped. The two ends of the fourth support are respectively rotationally connected with the opposite edges of the bottom plate 1. The fourth support is rotatable between a storage position and a support position. When the fourth support is in the storage position, it is arranged on one side of the bottom plate 1 and there is a gap between the fourth support and the bottom plate 1. When the fourth support is in the support position, it is arranged on the side of the bottom plate 1 opposite to the first and second battens 2 and 3, so that the bottom plate 1 is inclined to form a slope.

[0097] Based on the foregoing embodiments, in this embodiment, the fourth support is rotationally connected with the bottom plate 1 for adjusting the relative positions of the two. Assuming that the bottom plate 1 is arranged horizontally, when the fourth support is in the storage position, it is located on the side of the bottom plate 1. The gap between the fourth support and the bottom plate 1 is used for the user to insert his hand. The fourth support serves as a handle, and the user moves the bottom plate 1 by holding the fourth support with his hand. When the fourth support is in the support position, the fourth support is located on the bottom of the bottom plate 1 and close to one end of the bottom plate 1, so that the two ends of the bottom plate 1 form a height difference.

[0104] Based on the foregoing embodiment, in this embodiment, the fourth support and the bottom plate 1 are both provided with rotating shafts, and the two ends of the rotating connecting rod 43 are rotatably connected with the rotating shafts of the fourth support and the bottom plate 1, respectively. The connection between the rotating connecting rod 43 and the two rotating shafts is provided with an elastic sheet 44 having a wave-shaped elastic structure; in the rotating fourth support stage, the elastic sheet 44 is deformed to form a space for the rotation of the rotating connecting rod 43; in the fourth support stopping stage, the elastic sheet 44 presses the rotating connecting rod 43 and the rotating shafts to achieve the fastening of the fourth support and avoid the movement of the fourth support.

[0105] In some embodiments, the rotating connecting rod 43 has a long strip-shaped sheet structure, and the rotating connecting rod 43 is provided with a long strip-shaped adjusting hole. At least one of the rotating shafts of the fourth support and the bottom plate 1 is arranged in the adjusting hole, so that the distance between the fourth support and the bottom plate 1 can be adjusted by pushing or pulling along the adjusting hole.

[0106] When the bottom plate 1 is horizontally arranged and the fourth support is in the storage position, the fourth support is also horizontally arranged, and the fourth support can be pushed towards the bottom plate 1 until the two are in contact. When the fourth support has a cuboid shape, the height of the fourth support can be adjusted by rotating the fourth support.

[0107] In some embodiments, the golf sand trap practice board further comprises a protective shell, which is arranged on the bottom shell, and the first and second layers of hair are stored in the space formed between the protective shell and the bottom shell. In this way, the hair layers can be better protected from being squeezed and deformed during transportation and carrying.

[0108] In some embodiments, the protective shell has a display area that can display information such as advertisements, promotions, and corporate introductions.
