Description

Technical Field

[0001] This utility model relates to a storage and display device, and more specifically, to a hook device. Background Technology

[0002] Rail-mounted storage systems are widely used in homes, offices, factories, shops, and other fields. These systems are based on wall-mounted rails, with various hooks and shelves suitable for different applications attached to the rails using specialized connecting hooks. Because the connecting hooks are installed in a non-fixed manner, the various hooks and other products on the rails can be easily installed, removed, or repositioned as needed. Currently, many rail-mounted storage systems on the market use a method where the upper end of the hook connects to the sliding groove, or leave a large gap for easy disassembly, leading to instability when the hook slides. Utility model patent CN217118102U discloses a rail hook device, including a rail bracket and a first hook, which is slidably connected to the rail bracket by inserting the first hook into the rail bracket and rotating it 90 degrees. However, in this utility model, the first hook is only connected to the rail bracket at its upper end, thus also suffering from the aforementioned problem of unstable hook sliding. Utility Model Content

[0003] Existing guide rail hook devices have few connection points between the hook and the guide rail, and the hook cannot be limited in multiple directions, resulting in instability during sliding. To overcome this defect, this utility model provides a hook device that can improve the stability of the hook during sliding.

[0004] The technical solution of this utility model is: a hook device, including a hook assembly and a mounting slide rail. The hook assembly includes a main body, and the mounting slide rail is provided with an upper sliding groove and a lower sliding groove. The main body is slidably connected to the upper sliding groove and the lower sliding groove. The slidable connection between the main body and the upper sliding groove and the lower sliding groove allows the hook assembly to form a multi-point connection with the mounting slide rail, making it easier to achieve multi-directional limiting of the hook assembly, eliminating the degree of freedom of movement of the hook assembly other than the sliding direction, thereby improving the stability of the hook assembly when sliding.

[0005] Preferably, the mounting rail includes a base plate and a boss protruding from the surface of the base plate. The back of the main body has a recess that fits into the boss. The boss has a stop parallel to the base plate. An upper sliding groove and a lower sliding groove are located between the base plate and the stop. The two sides of the boss fit against the recess, which restricts the lateral movement of the main body across the two sides of the boss. The stop acts like a barb on the boss, making the main body engage with the two sides of the boss and unable to disengage. Therefore, the engagement of the recess and the boss limits the hook assembly in the lateral direction of the mounting rail. The sliding connection between the main body and the upper and lower sliding grooves limits the hook assembly in the vertical direction of the mounting rail, that is, in the thickness direction of the mounting rail. This ensures that the hook assembly only has a degree of freedom of movement in the longitudinal direction of the mounting rail, thus ensuring that the hook assembly slides stably on the mounting rail.

[0006] Preferably, the bottom of the upper sliding groove is an undulating surface with alternating protrusions and recesses, while the bottom of the lower sliding groove is a flat surface. The main body has a locking part corresponding to the undulating groove bottom that can engage with the recesses, and an elastic piece corresponding to the flat groove bottom. The elastic piece reduces wobbling during the sliding of the hook assembly. When the hook assembly slides on the mounting rail, the locking parts pass through the protrusions and recesses one by one. When passing a protrusion, the protrusion presses against the locking part, and the pressure of the protrusion on the locking part tends to gradually lift the main body. Simultaneously, as the main body is lifted, the distance between the elastic piece and the flat groove bottom decreases accordingly. The elastic piece can adapt to the reduced distance through its own elastic deformation, thus ensuring that the locking part can smoothly pass over the protrusion, meaning the protrusion will not obstruct the sliding of the hook assembly. When the snap-fit ​​part passes through the recessed part, the pressure that lifts the main body disappears, the elastic sheet recovers its elasticity, and the bottom of the flat groove pushes the elastic sheet back down to reset the main body. The snap-fit ​​part snaps into the recessed part. If no sliding force is applied to the hook assembly at this time, the hook assembly will stop due to the engagement between the snap-fit ​​part and the recessed part, preventing the hook assembly from moving easily during use.

[0007] Preferably, the top end of the protrusion and the bottom end of the recess are both smooth curved surfaces. This reduces resistance when the engaging portion moves over the protrusion and out of the recess.

[0008] Preferably, the main body is an injection-molded part, and the elastic sheet is integrally molded with the main body. When using an integral molding method, the elastic sheet and the main body can be generated simultaneously, which facilitates efficient manufacturing.

[0009] Preferably, the hook assembly also includes a hanging component, with a clamping part on the main body, and the hanging component is rotatably connected to the clamping part. The hanging component is used to hang, store, or display items. The rotatable connection between the hanging component and the clamping part allows the hanging component to be flipped, thus switching between the use and storage states.

[0010] Preferably, the clamping part is a flexible arc-shaped clamp seat, and the suspension component is detachably installed in the clamping part. The flexible arc-shaped clamp seat facilitates the removal of the suspension component, so that different types and functions of suspension components can be replaced for different application scenarios.

[0011] Preferably, the main body features a detachable panel. The panel can be replaced according to the application scenario to better match the scene and serve a better purpose of prompting, labeling, or decoration.

[0012] Preferably, the mounting rail is provided with fastener mounting holes. These holes can be used to install fasteners such as cement nails and screws, allowing the mounting rail to be installed on a supporting surface such as a wall or wooden board.

[0013] Alternatively, the mounting rail has a magnet on the back. The mounting rail can also be quickly connected to the metal support surface via the magnet.

[0014] The beneficial effects of this utility model are:

[0015] Improve the stability of the hook assembly. In this invention, the hook assembly and the mounting slide rail form a multi-point connection, which makes it easier to achieve multi-directional limiting of the hook assembly, eliminates the degree of freedom of movement of the hook assembly other than the sliding direction, and thus improves the stability of the hook assembly when sliding; in addition, the elastic sheet can also reduce the shaking of the hook assembly when sliding, and the undulating groove bottom can prevent the hook assembly from moving easily during use.

[0016] It offers multiple functions. The suspension components and panel in this utility model are easy to replace, and there are multiple options for installing the slide rail, making it better adaptable to different application scenarios and easier to use. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1:

[0028] like Figures 1 to 5 As shown, a hook device includes a hook assembly 1 and a mounting rail 2. The hook assembly 1 includes a main body 101 and a hook 102. The main body 101 is an injection-molded part, and the hook 102 is located at the bottom of the main body 101 and is integrally formed with the main body 101. The mounting rail 2 includes a base plate 203 and a boss 204. The boss 204 protrudes from the surface of the base plate 203 and is integrally injection-molded with the base plate 203. The boss 204 is oval in shape, and its long axis is aligned with the length direction of the base plate 203. During normal installation of the slide rail 2, the base plate 203 is fixed against a vertical or near-vertical support surface. The long axis of the boss 204 is located in a horizontal plane. An upper sliding groove 201 is provided on the upward-facing circumferential surface of the boss 204, and a lower sliding groove 202 is provided on the downward-facing circumferential surface of the boss 204. A retaining edge 205 is provided on the boss 204, which is parallel to the base plate 203 and integrally formed with the boss 204. The upper sliding groove 201 and the lower sliding groove 202 are located between the base plate 203 and the retaining edge 205, and the retaining edge 205 forms the outer groove of the upper sliding groove 201 and the lower sliding groove 202. The back of the main body 101 has a recess 103 that fits into the boss 204. The main body 101 straddles the boss 204 through the recess 103. The upper and lower sides of the recess 103 are each provided with an inwardly recessed protrusion, namely an upper protrusion 109 and a lower protrusion 110. The upper protrusion 109 and the lower protrusion 110 are integrally formed with the main body 101. The upper protrusion 109 is slidably embedded in the upper sliding groove 201, and the lower protrusion 110 is slidably embedded in the lower sliding groove 202, so that the main body 101 forms a sliding connection with the upper sliding groove 201 and the lower sliding groove 202. The bottom of the upper sliding groove 201 has protrusions and recesses. The protrusions are triangular prisms, and the recesses are funnel-shaped, consisting of two parallel left and right sides and two front and rear inclined surfaces. The protrusions and recesses are spaced evenly to form an undulating groove bottom. The bottom of the lower sliding groove 202 is a flat groove bottom. The part of the main body 101 corresponding to the undulating groove bottom, i.e., the upper protrusion, has a locking part 104 that can be engaged with the recess. The part of the main body 101 corresponding to the flat groove bottom, i.e., the lower protrusion, has an elastic sheet 105. The elastic sheet 105 is integrally formed with the main body 101. The top of the protrusion and the bottom of the recess are both smooth curved surfaces.

[0029] The hook assembly 1 also includes a suspension member 108, which is an S-shaped hook made of bent steel wire, having a connecting part and a hooking part, with the steel wire in the connecting part being straight. The main body 101 has a clamping part 106 inside, consisting of two elastic arc-shaped clamping seats. The connecting part of the suspension member 108 is fitted into the elastic arc-shaped clamping seats, allowing the suspension member 108 to rotate within and be removed from the clamping part 106. The main body 101 has a detachable panel 107 for covering the interior of the main body 101. The panel 107 can be configured with various colors and patterns for different application scenarios. The mounting rail 2 has fastener mounting holes for installing fasteners such as cement nails and screws to fix the mounting rail 2 to a supporting surface such as a wall or wooden board.

[0030] When the hook assembly 1 slides on the mounting rail 2, the engaging part 104 passes through the protrusions and recesses one by one. When passing through the protrusions, the protrusions press against the engaging part 104. The pressure of the protrusions on the engaging part 104 tends to gradually lift the main body 101. At the same time, as the main body 101 is lifted, the distance between the elastic piece 105 and the bottom of the planar groove also decreases accordingly. The elastic piece 105 can adapt to the reduction of the distance between itself and the bottom of the planar groove through its own elastic deformation, thereby ensuring that the engaging part 104 can smoothly pass over the protrusions, that is, the protrusions will not hinder the sliding of the hook assembly 1. When the locking part 104 passes through the recessed part, the pressure that lifts the main body 101 disappears, the elastic sheet 105 elastically recovers, and the bottom of the flat groove pushes the elastic sheet back down to reset the main body. The locking part 104 engages with the recessed part. If no sliding force is applied to the hook assembly 1 at this time, the hook assembly 1 will stop due to the engagement between the locking part 104 and the recessed part, preventing the hook assembly 1 from moving easily during use.

The back of the main body 101 has a recess 103 that fits and engages with the boss 204. The main body 101 straddles the boss 204 through the recess 103. The recess 103 has an inwardly recessed protrusion on its upper and lower sides, namely an upper protrusion 109 and a lower protrusion 110.

The part of the main body 101 corresponding to the undulating groove bottom, that is, the upper protrusion, is provided with a snap-fit ​​part 104 that can be snapped into the recess. The part of the main body 101 corresponding to the flat groove bottom, that is, the lower protrusion, is provided with an elastic sheet 105. The elastic sheet 105 is integrally formed with the main body 101.

[0033] The hook assembly 1 also includes a suspension member 108, which is an S-shaped hook made of bent steel wire, having a connecting part and a hooking part, with the steel wire in the connecting part being straight.

The mounting rail 2 has fastener mounting holes for installing fasteners such as cement nails and screws to fix the mounting rail 2 to a supporting surface such as a wall or wooden board. The rest is the same as in Embodiment 1.

[0034] When the hook assembly 1 slides on the mounting rail 2, the engaging part 104 passes through the protrusions and recesses one by one. When passing through the protrusions, the protrusions press against the engaging part 104. The pressure of the protrusions on the engaging part 104 tends to gradually lift the main body 101. At the same time, as the main body 101 is lifted, the distance between the elastic piece 105 and the bottom of the planar groove also decreases accordingly. The elastic piece 105 can adapt to the reduction of the distance between itself and the bottom of the planar groove through its own elastic deformation, thereby ensuring that the engaging part 104 can smoothly pass over the protrusions, that is, the protrusions will not hinder the sliding of the hook assembly 1. When the locking part 104 passes through the recessed part, the pressure that lifts the main body 101 disappears, the elastic sheet 105 elastically recovers, and the bottom of the flat groove pushes the elastic sheet back down to reset the main body. The locking part 104 engages with the recessed part. If no sliding force is applied to the hook assembly 1 at this time, the hook assembly 1 will stop due to the engagement between the locking part 104 and the recessed part, preventing the hook assembly 1 from moving easily during use.

The mounting rail 2 includes a base plate 203 and a boss 204. The boss 204 protrudes from the surface of the base plate 203 and is integrally injection-molded with the base plate 203. The boss 204 is oval in shape, and its long axis is aligned with the length direction of the base plate 203.

An upper sliding groove 201 is provided on the upward-facing circumferential surface of the boss 204, and a lower sliding groove 202 is provided on the downward-facing circumferential surface of the boss 204. A retaining edge 205 is provided on the boss 204, which is parallel to the base plate 203 and integrally formed with the boss 204. The upper sliding groove 201 and the lower sliding groove 202 are located between the base plate 203 and the retaining edge 205, and the retaining edge 205 forms the outer groove of the upper sliding groove 201 and the lower sliding groove 202. The back of the main body 101 has a recess 103 that fits into the boss 204. The main body 101 straddles the boss 204 through the recess 103. The upper and lower sides of the recess 103 are each provided with an inwardly recessed protrusion, namely an upper protrusion 109 and a lower protrusion 110. The upper protrusion 109 and the lower protrusion 110 are integrally formed with the main body 101. The upper protrusion 109 is slidably embedded in the upper sliding groove 201, and the lower protrusion 110 is slidably embedded in the lower sliding groove 202, so that the main body 101 forms a sliding connection with the upper sliding groove 201 and the lower sliding groove 202. The bottom of the upper sliding groove 201 has protrusions and recesses. The protrusions are triangular prisms, and the recesses are funnel-shaped, consisting of two parallel left and right sides and two front and rear inclined surfaces. The protrusions and recesses are spaced evenly to form an undulating groove bottom. The bottom of the lower sliding groove 202 is a flat groove bottom.

The suspension member 108 can rotate within the clamping part 106 and can also be removed from it. Unlike embodiment 1, in this embodiment, the suspension member 108 also includes a straight hook, facilitating the display of boxed tool sets. The straight hook is welded from two U-shaped steel wires. One U-shaped steel wire is located in the horizontal plane, with two parallel sections on both sides extending out of the main body 101, forming a hanging part. The end of the hanging part is slightly curved upwards, and the middle section is straight, fitting into the clamping part 106, forming the connecting part. Another U-shaped steel wire is vertically welded to the middle section of the U-shaped steel wire in the horizontal plane and closely attached to the interior of the main body 101, forming a support to enhance the load-bearing capacity of the hanging part and prevent the U-shaped steel wire in the horizontal plane from flipping downwards after being hung with a load. The main body 101 is provided with a detachable panel 107 to cover the interior of the main body 101. The panel 107 can be configured with various colors and patterns for selection in different application scenarios. The mounting rail 2 is provided with fastener mounting holes for installing fasteners such as cement nails and screws to fix the mounting rail 2 to the supporting surface such as walls and wooden boards.

[0038] When the hook assembly 1 slides on the mounting rail 2, the engaging part 104 passes through the protrusions and recesses one by one. When passing through the protrusions, the protrusions press against the engaging part 104. The pressure of the protrusions on the engaging part 104 tends to gradually lift the main body 101.
