Description

Technical Field

[0001] This application relates to the field of accessory installation auxiliary devices, specifically to a hole accessory installation structure. Background Technology

[0002] For structural components with holes on the inner edge, when accessories need to be installed, they are usually installed by direct adhesive bonding or with the help of auxiliary parts. If adhesive is used, once disassembled, it can only be re-adheded with adhesive. When reinstallation is no longer needed, the residual adhesive affects the appearance, is difficult to clean, and may damage the accessories during cleaning. When auxiliary parts are needed for installation, it is usually necessary to make a connection part on the structural component for fixing the auxiliary parts or use the auxiliary parts to clamp and fix them before installing the accessories. The clamping and fixing method of using auxiliary parts has certain requirements on the structure. Making a connection part on the structural component will affect the shape of the structural component. When the accessories are no longer used, the shape of the structural component cannot be restored.

[0003] This application provides a hole-mounted fitting installation structure that enables convenient installation of fittings using holes. Utility Model Content

[0006] A hole fitting installation structure includes a cover plate with a movable locking foot on the back. The locking foot cooperates with a locking structure. In use, the cover plate presses against the outer end face of the hole. When the locking foot engages with the opening edge of the hole, the cover plate is locked. When the locking foot separates from the opening edge of the hole, the cover plate is unlocked.

[0007] Furthermore, the cover plate has a groove that slides with a corresponding locking foot cup, which moves along the groove to approach or move away from the opening edge of the hole.

[0008] Furthermore, the locking cup has a limiting part that mates with the groove, and the limiting part can be separated from the groove.

[0009] Furthermore, the locking structure clamps the cover plate and the locking foot cup against the opening edge of the hole by pulling up the locking foot cup.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0024] refer to Figures 1 to 3,like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a hole fitting installation structure, including a cover plate 1. The back of the cover plate 1 has a movable locking cup 2. The locking cup 2 is used in conjunction with a locking structure. After the locking cup 2 moves into place, it is locked by the locking structure. In use, the cover plate 1 presses against the outer end face of the hole. When the locking cup 2 is hooked and connected with the opening edge of the hole, the opening edge of the hole is clamped between the cover plate 1 and the locking cup 2, and the cover plate 1 is locked. When the locking cup 2 separates from the opening edge of the hole, the cover plate 1 is unlocked.

[0025] Preferably, the number of locking feet 2 in this application can be set to one, two or three. When the number of locking feet 2 is one, the cover plate 1 can be provided with a fixed slot that hooks into the opening edge of the hole. During installation, the slot is first inserted into the opening edge of the hole and then the cover plate 1 is pressed tightly. Then the locking feet 2 are used to lock the cover plate 1. When the number of locking feet 2 is more than one, multiple locking feet 2 can be used to lock the cover plate 1.

[0026] One installation method of the locking foot cup 2 is as follows: the locking foot cup 2 is hinged to the cover plate 1. The locking foot cup 2 has a cam part. The rotation of the locking foot cup 2 controls the protrusion of the cam part to enter the inner side of the opening edge of the hole to form a hook connection. The locking structure can be an elastic clamping structure or a floating lock head that cooperates with the groove located on the hinge shaft for locking. When the locking structure is an elastic clamping structure, the locking structure relies on the friction force acting on the hinge shaft to prevent the locking foot cup 2 from rotating freely.

[0027] In this embodiment, another installation method for the locking foot cup 2 is as follows: the cover plate 1 has a groove 11 that slides with the corresponding locking foot cup 2. The locking foot cup 2 moves along the groove 11 to approach or move away from the opening edge of the hole. The groove 11 can also be straight or curved. The locking foot cup 2 can move to a set end or both ends of the groove 11 to approach the opening edge, depending on the direction of the groove 11. With the above structure, holes with a certain diameter range can be used, and the adaptability is better.

[0028] Specifically, one installation method for the locking foot cup 2 is as follows: a sliding groove that mates with the corresponding side of the groove 11 can be provided on the limiting part 21 of the locking foot cup 2, so that one or both sides of the limiting part 21 form a concave-convex fit structure, making it difficult for the limiting part 21 to separate from the groove 11. The locking foot cup 2 can be moved along the groove 11 in the corresponding direction by the elastic pushing structure or the screw pushing structure provided on the cover plate 1, thereby achieving locking. Alternatively, a rotatable locking rod provided on the cover plate 1 can be used to prevent the locking foot cup 2 from moving in the opposite direction after it has moved into place. The cover plate 1 is locked. A limiting structure to prevent the cover plate 1 from rotating can be selected between the cover plate 1 and the structural component as needed. The limiting structure can be a limiting shaft or a limiting groove or a clamping screw set on the cover plate 1 that can act on the structural component. In this embodiment, another installation form of the locking foot cup 2 is: the locking foot cup 2 has a limiting part 21 that cooperates with the groove 11, and the limiting part 21 can be separated from the groove 11, so that the locking foot cup 2 can be easily replaced. The locking structure locks the cover plate 1 by pulling up the locking foot cup 2, so that the cover plate 1 and the locking foot cup 2 clamp the opening edge of the hole.

[0029] In this embodiment, the locking foot cup 2 is installed in a way that allows it to be separated from the groove 11, making the locking foot cup 2 easy to replace.

[0030] One type of locking structure is as follows: the top of the locking foot cup 2 has a protruding lead screw, and the nut threaded onto the lead screw can be pressed against the cover plate 1.

[0031] Another type of locking structure is as follows: the limiting part 21 has a pin that passes through radially, and the corresponding end of the groove 11 is provided with an upward reset elastic element. When the pin moves to the elastic element, the elastic element lifts the pin, thereby lifting the locking foot cup 2 to achieve locking.

[0032] Another type of locking structure is as follows: the locking structure is a locking bolt 4 that is threadedly connected to the limiting part 21, and the locking bolt 4 presses against the cover plate 1. The locking foot cup 2 is locked or released by turning the locking bolt 4.

[0033] In this embodiment, another preferred locking structure is as follows: the locking structure includes a locking bolt 4 and a washer 3. The locking bolt 4 passes through the washer 3 and is connected to the limiting part 21. The washer 3 presses against the cover plate 1. By using the washer 3, a small locking bolt 4 can be used, and the elastic deformation of the washer 3 can prevent the locking bolt 4 from loosening easily, making the connection reliable, stable, and convenient to use.

[0034] Specifically, the cover plate 1 is provided with a limiting groove 12 that slides with the gasket 3. The limiting groove 12 is formed by an annular reinforcing rib 13 provided at the groove 11, so that the gasket 3 and the locking bolt 4 can be installed in a concealed manner, making it safer to use and more aesthetically pleasing.

[0035] To facilitate installation, the limiting part 21 is square. The limiting part 21 rotates inside the groove 11, making it more reliable and convenient to tighten the locking bolt 4.

[0036] In this application, the locking foot cup 2 also includes a cup body 22 connected to the limiting part 21, and the cup body 22 has a limiting inclined surface that can hook with the opening edge of the hole. By setting the limiting inclined surface, this application can be installed in holes with different edge thicknesses without adjusting the length of the locking bolt 4.

[0037] To simplify the structure, ensure high strength and long service life, the limiting part 21 is fixedly connected to the cup body 22.

[0038] In this application, the cover plate 1 is provided with an installation structure for installing accessories.

[0039] For the use of this application, please refer to Figure 3 As shown, it is installed in the sound hole of the musical instrument, so that the accessory is sunk into the sound hole for concealment.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
