[0033] In daily life, a sheet is laid on the surface of a mattress; the sheet is secured by placing the sheet fastener of this application under the four corners of the mattress. The specific implementation method is as follows:
[0034] This application protects a sheet fastener, such as... Figure 1-6 As shown, the sheet fastener includes: a base 1, at least one support plate 2, and at least one locking member 3; the base 1 extends horizontally and is configured to be placed on the lower surface of the mattress during use; at least one sliding groove assembly 11 is provided at the edge of the base 1; each support plate 2 has an insert plate assembly 21 at its bottom, which is embedded in the sliding groove assembly 11 in the installed state to connect the support plate 2 with the base 1, and a locking plate 22 is provided on the side of the support plate 2; the locking member 3 is engaged with the locking plate 22, and the sheet is placed between the locking member 3 and the locking plate 22 in use to fix the sheet; the locking plate 22 has a through hole 221, which can be a rectangular hole or a circular hole; the locking member 3 has a protrusion 31, which is inserted into the through hole 221 of the locking plate 22 in the installed state.
[0035] To better understand some embodiments of this application, one application scenario of the sheet fastener protected by this application is as follows: before fastening the sheet, the locking member 3 is not engaged with the clamping plate 22; the base 1 is placed on the lower surface of the corner of the mattress, and the support plate 2 is correspondingly attached to the side of the mattress. By laying the sheet and letting it hang naturally to the side of the mattress, the locking member 3 is engaged with the clamping plate 22 to achieve the fastening of the sheet. It can be seen that the sheet fastener can quickly fasten the sheet, is easy to operate, and has a simple and reliable structure.
[0036] In some implementations, such as Figure 1-2 As shown, there are two support plates 2, and two corresponding locking elements 3. Similarly, there are two sliding groove assemblies 11 and two insert plate assemblies 21. The support plates 2 are respectively attached to the two sides of the mattress. After the support plates 2 and the locking elements 3 are engaged, they can better fix the bed sheet and prevent the bed sheet from loosening or slipping during use.
[0037] In some implementations, such as Figure 3-4 As shown, the sliding groove assembly 11 is provided with an installation groove 111, and the insert plate assembly 21 is provided with an insertion block 211, which is inserted into the installation groove 111. The installation groove 111 is correspondingly provided with an installation block 112, and the insertion block 211 is correspondingly provided with an insertion slot 212, which is inserted into the insertion slot 212. By moving the insert plate assembly 21, with the insertion block 211 inserted into the installation groove 111 and the installation block 112 inserted into the insertion slot 212, stable installation between the support plate 2 and the base 1 is achieved. Simultaneously, thanks to the sliding groove design, the support plate 2 and the base 1 can be flexibly disassembled. Therefore, this device, through the split design between the support plate 2 and the base 1, improves the stability, flexibility, and versatility of the sheet fastener.
[0038] Furthermore, the slide rail assembly 11 also includes a convex locking block 113. The lower surface of the insertion block 211 of the insert plate assembly 21 is provided with a limiting groove 214. In the installed state, the convex locking block is placed in the limiting groove to realize the cooperation between the insert plate assembly and the slide rail assembly. Preferably, the cross-section of the convex locking block 113 is arc-shaped, and the limiting groove 214 is an arc-shaped groove to facilitate the engagement and disengagement of the convex locking block 113 and the limiting groove 214.
[0039] When installing the support plate 2, the plug-in block 211 is embedded into the mounting groove 111. During the embedding process, the limiting groove 214 moves with the plug-in block 211 until it engages with the convex locking block 113, thus achieving a stable connection between the support plate 2 and the base 1, thereby preventing the support plate 2 from easily detaching from the base 1 during use. The base 1 and the support plate 2 of this device are preferably made of plastic. When it is necessary to disassemble the support plate 2 from the base 1, a reverse force is applied to the support plate 2. Within a certain deformation range of the limiting groove 214 or the convex locking block 113, the convex locking block 113 slides out from the limiting groove 214, thereby separating the support plate 2 from the base 1.
[0040] In some implementations, such as Figure 3-5 As shown, a limiting block 213 is provided on one side of the plug-in block 211 to prevent the sliding groove assembly 11 from being over-embedded in the plug-in plate assembly 21. Specifically, when installing the support plate 2, the plug-in block 211 at the end away from the limiting block 213 is first embedded in the mounting groove 111. After being embedded to a certain length, one side of the limiting block 213 contacts the mounting block 112, preventing it from being further embedded in the mounting groove 111. At the same time, the limiting groove 214 engages with the protruding locking block 113. This arrangement can avoid damage caused by over-installation, while ensuring the correct installation position of the support plate 2 and the base 1, thus improving the accuracy and reliability of the installation.
[0041] In some implementations, such as Figure 5-6 As shown, the card plate 22 extends outward from the support plate 2, and a snap-fit cavity 24 is provided between the support plate 2 and the card plate 22; the locking member 3 is provided with locking parts 32 on both sides, and each locking part 32 is configured to be inserted into the snap-fit cavity 24 to realize the connection between the locking member 3 and the card plate 22; when fixing the bed sheet, each locking part 32 of the locking member 3 is embedded in the snap-fit cavity 24, so that the bed sheet is fixed between the locking member 3 and the support plate 2; at the same time, since the locking member 3 is provided with a protrusion 31, when the protrusion 31 is embedded in the through hole 221 of the card plate 22, the bed sheet is further fixed.
[0042] In some implementations, such as Figure 1 and Figure 6 As shown, the card plate 22 also includes a hand-held block 33, which extends downward along the edge of one of the locking parts 32 and is integrally formed with the card plate 22. When it is necessary to change the bed sheet, the hand-held block 33 can be pushed away from the end of the support plate 2 to remove the locking member 3 from the card plate 22. The hand-held block 33 makes it easier to remove the locking member 3, making the operation of changing the bed sheet more convenient and labor-saving.
[0043] In some implementations, such as Figure 4 As shown, a reinforcing rib 23 is provided between the card plate 22 and the support plate 2. Furthermore, the reinforcing rib 23 is provided on both sides of the card plate 22 to enhance the connection strength between the card plate 22 and the support plate 2 and improve the overall structural strength of the support plate 2 and the card plate 22.
[0044] In some implementations, such as Figure 3 As shown, the upper surface of the base 1 is provided with a plurality of first anti-slip strips 12; preferably, the number of first anti-slip strips 12 is 4. The first anti-slip strips 12 are used to increase the friction between the base 1 and the lower surface of the mattress; to prevent the sheet fastener from sliding on the mattress, to ensure the stability of its fixed position, and to avoid the sheet from becoming loose due to the displacement of the sheet fastener.
[0045] In some implementations, such as Figure 1 As shown, the outer surface of the hand-held block 33 is provided with a plurality of second anti-slip strips 331; preferably, the number of second anti-slip strips 331 is 3, so as to increase the friction between the hand-held block 33 and the hand, so that the user can hold the hand-held block 33 when disassembling the locking piece 3 and prevent the hand from slipping.
[0046] The working principle of the sheet fastener in this embodiment is as follows:
[0047] The bed sheet fastener of this technical solution secures the bed sheet through the cooperation of a base 1, a support plate 2, and a locking element 3. In use, the base 1 is first placed on the underside of the mattress. The sliding groove assembly 11 on the edge of the base 1 engages with the insert plate assembly 21 at the bottom of the support plate 2, connecting the support plate 2 to the base 1. The support plate 2 fits against the side of the mattress, and its side locking plate 22 engages with the locking element 3. When the locking element 3 engages with the locking plate 22, the locking part 32 of the locking element 3 embeds into the locking cavity 24 between the locking plate 22 and the support plate 2, fixing the bed sheet between the locking element 3 and the locking plate 22. Simultaneously, the through hole 221 on the locking plate 22 cooperates with the protrusion 31 on the locking element 3, further enhancing the fixing effect. Furthermore, the sliding groove assembly 11, through the protruding locking block 113, cooperates with the limiting groove 214 of the insert plate assembly 21, preventing the support plate 2 from easily detaching from the base 1 during use.
[0048] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
