Description

Technical Field

[0001] This utility model relates to the field of bed sheet fastening technology, specifically a bed sheet fastener. Background Technology

[0002] In daily life, bed sheets are inevitably used, and in most cases, they are simply laid flat on the mattress. Because the connection between the sheet and the mattress is relatively casual, the sheet tends to shift significantly relative to the mattress after a period of use, requiring frequent adjustments and causing inconvenience for the user.

[0003] To ensure user safety, most modern bed sheet fasteners use side-clamp type fasteners to secure the sheets. These fasteners clamp the sheets to the mattress to hold them in place. However, these fasteners are prone to loosening during use, and the sheets can easily detach from the fasteners, resulting in an unsatisfactory securing effect. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a bed sheet fastener that solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution:

[0006] This utility model discloses a bed sheet fastener, including a first clamp and a second clamp.

[0007] The first lower plate is located in the lower half of the first clamping plate;

[0008] The first upper plate is located in the upper half of the first clamping plate, and side plates are fixedly connected to both sides.

[0009] Mounting holes are formed on the side surface of the first upper plate;

[0010] The second lower plate is located in the lower half of the second clamping plate;

[0011] The second upper plate is located in the upper half of the second clamping plate and is smaller than the first upper plate. Side plates are also fixed on both sides.

[0012] The fixed shaft is fixed to the outer surface of the side plate of the second upper plate, and its position corresponds to the mounting hole. By fitting the second upper plate inside the first upper plate, the fixed shaft is installed in the mounting hole, so that the first clamping plate and the second clamping plate are connected, thereby reducing unnecessary parts.

[0013] Furthermore, the surface of the first upper plate is provided with two corresponding first isolation grooves.

[0014] Furthermore, the first upper plate is divided into a set of movable plates and two sets of fixed plates by two first isolation grooves.

[0015] Furthermore, the inner wall of the fixing plate is fixed with the first gear teeth.

[0016] Furthermore, a second isolation groove is provided on the surface of the second upper plate near the two side plates.

[0017] Furthermore, the second upper plate is divided into a support plate by a second isolation groove, and a second gear is fixed on the top of the support plate corresponding to the position of the first gear tooth.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model has a simple structure. When in use, pressing the movable plate opens the first and second lower clamping plates, and the bed sheet and mattress are secured in the cavity between the first and second lower clamping plates. Then, the first and second lower clamping plates are pressed together. The ratchet engagement of the first gear and the second gear ensures that the first and second clamping plates can only move in one direction, preventing the first and second lower clamping plates from opening automatically, thereby achieving the effect of fixing the bed sheet.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-8 The system includes a first clamping plate 1 and a second clamping plate 2; a first lower clamping plate 3, located in the lower half of the first clamping plate 1, which is semi-circular in shape and has several protruding strips fixed on its inner wall; the bottom end of the first lower clamping plate 3 has a wavy toothed pattern, and the outer wall is fixed with anti-slip strips; a first upper clamping plate 4, located in the upper half of the first clamping plate 1, with side plates fixedly connected to both sides; the first upper clamping plate 4 and the first lower clamping plate 3 are an integral structure, with a baffle connected in the middle of the inner wall; mounting holes 5 are opened on the side surface of the first upper clamping plate 4, and have a structure basically the same as the first lower clamping plate 3; the mounting holes 5 and the first lower clamping plate 3 can be spliced ​​to form a cavity, through which the bed sheet is fixed; and a second lower clamping plate 10, located in the lower half of the second clamping plate 2, which has a structure basically the same as the first lower clamping plate 3; the curve at the bottom end can engage with the wavy toothed pattern of the first lower clamping plate 3; the second lower clamping plate 10 and the first lower clamping plate 3 are an integral structure, with several protruding strips fixed on its inner wall, and the bottom end of the first lower clamping plate 3 has a wavy toothed pattern, and the bottom end of the first lower clamping plate 10 can engage with the wavy toothed pattern of the first lower clamping plate 3. The first and second upper plates 10 are joined together to form a cavity, through which the bed sheet is fixed. The second upper plate 11 is located in the upper half of the second clamping plate 2 and is smaller in size than the first upper plate 4. Side plates are also fixed on both sides. The baffle fixed on the inner wall of the second upper plate 11 corresponds to the baffle on the inner wall of the first upper plate 4, thereby blocking the cavity formed by the first and second lower plates 10. The second upper plate 11 can be installed inside the first upper plate 4, so that the second upper plate 11 and the first upper plate 4 form a separate cavity. The fixing shaft 12 is fixed on the outer surface of the side plate of the second upper plate 11 and its position corresponds to the mounting hole 5. By fitting the second upper plate 11 into the first upper plate 4 and installing the fixing shaft 12 into the mounting hole 5, the first clamping plate 1 and the second clamping plate 2 are connected, thereby reducing unnecessary parts.

[0031] The surface of the first upper plate 4 has two corresponding first isolation grooves 6. The first upper plate 4 is divided into a set of movable plates 7 and two sets of fixed plates 8 by the two first isolation grooves 6. The outer surface of the movable plate 7 is fixed with anti-slip strips, and the two sides of the fixed plate 8 are fixed to the side plates. The inner wall of the fixed plate 8 is fixed with first gear teeth 9.

[0032] A second isolation groove 13 is formed on the surface of the second upper plate 11 near the side plates. A support plate 14 is divided in the middle of the second upper plate 11 by the second isolation groove 13. A second gear 15 is fixed to the top of the support plate 14 corresponding to the position of the first gear tooth 9. After the first upper plate 4 and the second upper plate 11 are installed, the second gear 15 meshes with the first gear tooth 9. Since both the first gear tooth 9 and the second gear 15 are ratchet structures, they cannot move in opposite directions when meshed, thus preventing the movement of the first clamping plate 1 and the second clamping plate 2. Simultaneously, it restricts the opening and closing of the first lower plate 3 and the second lower plate 10. The support plate 14... A through hole is provided at the position of the movable plate 7, and a boss is fixed on the top of the support plate 14 near the movable plate 7. The top of the boss abuts against the inner surface of the movable plate 7. When the movable plate 7 is pressed, the inner wall of the movable plate 7 pushes the boss of the support plate 14 to move, so that the support plate 14 and the movable plate 7 move together. When the support plate 14 moves, it drives the second gear 15 at the top to sink at the same time, so that the second gear 15 disengages from the first gear 9, thereby facilitating the movement of the first clamping plate 1 and the second clamping plate 2, and opening the first lower clamping plate 3 and the second lower clamping plate 10.

[0033] The working principle is as follows: the first clamping plate 1 and the second clamping plate 2 are assembled so that the second upper clamping plate 11 is locked inside the first upper clamping plate 4. The fixing shafts 12 on both sides of the second upper clamping plate 11 are locked inside the mounting holes 5, which facilitates the rotation of the first clamping plate 1 and the second clamping plate 2. When the bed sheet is fixed and laid flat, the movable plate 7 is pressed to push the support plate 14 to move inward. The support plate 14 drives the second gear 15 to disengage from the first gear 9. When the movable plate 7 and the support plate 14 move, the first isolation groove 6 on both sides of the movable plate 7 and the second isolation groove 13 on both sides of the support plate 14 prevent the side plates of the first upper clamping plate 4 and the second upper clamping plate 11 from moving with the movable plate 7, thereby maintaining the engagement of the fixing shafts 12 and the mounting holes 5, so that the first clamping plate 1 and the second clamping plate 2 are always connected. After the second gear 15 disengages from the first gear 9, the first lower plate 3 and the second lower plate 10 open outwards, securing the sheet and mattress together within their cavities. Then, the first lower plate 3 and the second lower plate 10 are pushed inwards to secure the sheet to the mattress. The wavy teeth at the ends of the first lower plate 3 and the second lower plate 10 further enhance the sheet's anti-slip properties. After the movable plate 7 is released, it automatically resets, allowing the support plate 14 to drive the second gear 15 to continue meshing with the first gear 9. This ensures that the first gear 9 and the second gear 15 can only close the first lower plate 3 and the second lower plate 10, preventing them from opening automatically and thus preventing the sheet from detaching from the mattress, further ensuring the sheet's secure hold.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
