Technical Field

The invention relates to a buckle component, in particular to a buckle component which pushes a hook through magnetic force.

Background

Generally, a server includes a cabinet and a chassis installed in the cabinet, and the chassis is usually locked to the cabinet by screws, however, the screw locking not only has a problem that the disassembling and assembling operation needs to be performed by an external tool, but also has a problem that a lot of locking time is consumed. That is, the assembler often takes a lot of time to disassemble and assemble the chassis. In addition, in the process of disassembling and assembling the chassis, the screws are likely to be lost. Therefore, in order to solve the above problems, it is seen that the case is fixed to the cabinet by using the movable fixing structure of the hook and the slot, so as to achieve the effects of facilitating the detachment and preventing the loss of the screws.

The existing movable hook is usually connected with an elastic member, so that the elastic force of the elastic member is utilized to push the hook out of the housing and fix the hook at a clamping position, and the hook can be temporarily retracted into the housing to a release position under the action of external force due to the characteristic that the elastic member can be deformed under stress. However, the elastic member has a problem of elastic fatigue or even deformation after long-term or frequent use.

The buckle assembly comprises a shell, a hook piece, a first magnetic piece and a second magnetic piece. The clamping hook piece is arranged in the shell and slides between a clamping position and a releasing position. When the clamping hook piece is positioned at the clamping position, the clamping hook piece is used for being buckled with the clamping groove. When the clamping hook piece is located at the releasing position, the clamping hook piece is separated from the clamping groove. The first magnetic piece is fixed on the shell, and the second magnetic piece is fixed on the clamping hook piece. The first magnetic piece and the second magnetic piece enable the clamping hook piece to be located at the clamping position.

According to the buckle assembly disclosed in the above embodiment, the first magnetic member is fixed to the housing, and the second magnetic member is fixed to the hook member, so that the hook member is located at the buckle position due to the magnetic force between the first magnetic member and the second magnetic member, and is used for buckling the buckle slot of the fixing frame. In addition, the buckle component utilizes the magnetic force to push the clamping hook piece to the buckle position, so that the problem that an elastic piece for providing movable clamping hook pushing force in the prior art is elastically fatigued or even deformed after long-term or frequent use can be solved.

The fastening assembly 1 includes a housing 10, a hook 20, a first magnetic member 30, a second magnetic member 40, a guiding member 50 and a pushing member 60.

The housing 10 includes a first side plate 110, a second side plate 120, a third side plate 130 and a fourth side plate 140 connected together. The first side plate 110 and the second side plate 120 are opposite to each other, the third side plate 130 and the fourth side plate 140 are opposite to each other, and the third side plate 130 and the fourth side plate 140 are located between the first side plate 110 and the second side plate 120. In addition, the first side plate 110 includes a through hole 111, the second side plate 120 includes a guiding hole 121, the third side plate 130 includes a sliding slot 131, and the fourth side plate 140 includes a through hole 141. In this embodiment, the housing 10 further includes two vertical walls 132 protruding from the third side plate 130, so that the sliding slot 131 is formed between the two vertical walls 132. The standing wall 132 is formed by bending the third side plate 130 by, for example, bending a sheet metal, or the standing wall 132 may be protruded from the third side plate 130 by welding, but the invention is not limited thereto.

The hook member 20 includes a pushed portion 210, a hooking portion 220 and a guiding post 230, and the hooking portion 220 and the guiding post 230 are respectively connected to two opposite sides of the pushed portion 210. The pushed portion 210 is slidably disposed in the sliding slot 131 of the third side plate 130, and the pushed portion 210 slides along a first sliding direction D1, so that the hook member 20 slides between a locking position and a releasing position. When the hook member 20 is located at the fastening position, the fastening portion 220 is inserted through the through hole 111 of the first side plate 110 and is used for fastening the fastening portion to the fastening groove 90; when the hook member 20 is located at the release position, the hook portion 220 is separated from the through hole 111 and the engaging groove 90. The guiding column 230 is slidably disposed through the guiding hole 121 of the second side plate 120. The end of the guiding post 230 away from the pushed portion 210 includes a stop plate 233, and the width W1 of the stop plate 233 is greater than the width W2 of the guiding hole 121. In the embodiment, the pushed portion 210 has a pushed inclined surface 211, and the angle between the normal direction N1 of the pushed inclined surface 211 and the first sliding direction D1 is, for example, 45 degrees, but the invention is not limited to the angle between the normal direction N1 and the first sliding direction D1.

The first magnetic member 30 and the second magnetic member 40 are both sleeved on the guiding column 230 and located between the second side plate 120 and the pushed portion 210. The first magnetic member 30 is fixed to the second side plate 120, and the second magnetic member 40 is fixed to the pushed portion 210, so that the second magnetic member 40 is located between the first magnetic member 30 and the through hole 111. In the present embodiment, the first magnetic element 30 and the second magnetic element 40 are opposite to each other with the same polarity and mutually exclusive, so that the hook element 20 is located at the locking position. Specifically, the hook member 20 is continuously pushed toward the through hole 111 by the repulsive force between the first magnetic member 30 and the second magnetic member 40, and is pushed toward the through hole 111 to be located at the locking position.

The guide 50 is fixed to the fourth side plate 140 and corresponds to the through hole 141 of the fourth side plate 140. The guiding element 50 includes a guiding groove 51, and the guiding groove 51 is connected to the through hole 141 of the fourth side plate 140.

The pushing element 60 slidably penetrates through the guiding element 50, and the pushing element 60 slidably moves along a second sliding direction D2. The second sliding direction D2 of the pushing element 60 is perpendicular to the first sliding direction D1 of the pushed part 210. The end of the pushing member 60 close to the pushed portion 210 has a pushing inclined surface 610, and a normal direction N2 of the pushing inclined surface 610 is parallel to a normal direction N1 of the pushed inclined surface 211. The end of the pushing element 60 away from the pushed portion 210 includes a pressing portion 620, and the width W3 of the pressing portion 620 is greater than the width W4 of the through hole 141. In the embodiment, the second sliding direction D2 of the pushing element 60 is perpendicular to the first sliding direction D1 of the pushed portion 210, but the invention is not limited thereto. In other embodiments, the second sliding direction of the pushing element and the first sliding direction of the pushed portion may form an acute angle.

Referring to fig. 3 and fig. 4 together, fig. 4 is a schematic view of the hook member of fig. 3 in a release position. When the user wants to separate the hooking portion 220 from the through hole 111, a pushing force is applied to the pressing portion 620 of the pushing member 60 in a direction toward the third side plate 130, so that the pushing inclined surface 610 of the pushing member 60 pushes against the pushed inclined surface 211, and the pushed portion 210 is driven to slide in a direction away from the through hole 111 along the first sliding direction D1 against the mutual repulsive force between the first magnetic member 30 and the second magnetic member 40, so that the hooking member 20 moves from the hooking position (as shown in fig. 3) to the releasing position (as shown in fig. 4). When the user releases the pressing portion 620, the hook member 20 is pushed from the releasing position to the through hole 111 and located at the locking position due to the repulsive force between the first magnetic member 30 and the second magnetic member 40.

In the embodiment, the guiding hole 121 of the second side plate 120 limits the guiding column 230, and the two vertical walls 132 of the third side plate 130 limit the pushed portion 210, so as to assist in limiting and guiding the direction in which the pushed portion 210 slides after being stressed, but the invention is not limited thereto. For example, in other embodiments, the hook member may not have a guiding column, and only the two upright walls 132 of the third side plate 130 are used as a guiding and limiting means when the pushed portion 210 slides. Alternatively, in other embodiments, the third side plate may not be provided with a vertical wall, and only the guide hole 121 of the second side plate 120 and the guide post 230 of the hook member 20 are used as a guide and limit means when the pushed portion 210 slides.

It should be noted that the guide 50 of the present embodiment can be optional, and the invention is not limited thereto. For example, in other embodiments, the buckle assembly may not include the guide, in which case, the moving direction of the pushing element may be limited and guided only by the through hole of the fourth side plate. In addition, the latch assembly 1 of the present embodiment pushes the hook member 20 from the latching position to the releasing position through the pushing member 60 disposed on the fourth side plate 140, but the invention is not limited thereto. For example, in other embodiments, the housing of the buckle assembly may not be provided with the pushing element, but an external tool is used to push the hook element.

Furthermore, the present invention is not limited to the position characteristics of the first magnetic element 30 and the second magnetic element 40, and in other embodiments, as long as the first magnetic element is fixed to the housing, the second magnetic element is fixed to the hook element, the second magnetic element is located between the first magnetic element and the through hole, and the first magnetic element and the second magnetic element are arranged in the same polarity and opposite direction, the effect of enabling the hook element to be located at the fastening position can also be achieved by the mutual repulsion force between the first magnetic element and the second magnetic element.

Specifically, in the embodiment, since the first magnetic member 30 and the second magnetic member 40 are both sleeved on the guiding pillar 230 and located between the second side plate 120 and the pushed portion 210, the first magnetic member 30 and the second magnetic member 40 can respectively abut against the second side plate 120 and the pushed portion 210 through mutual repulsion, so that the first magnetic member 30 and the second magnetic member 40 can be respectively fixed on the second side plate 120 and the pushed portion 210 without an additional fixing manner, but the invention is not limited thereto. In other embodiments, the first magnetic member and the second magnetic member may be fixed to the second side plate and the pushed portion, respectively, for example, by an adhesive.

In the present embodiment, the hook member 20 is located at the locking position by the repulsive force between the first magnetic member 30 and the second magnetic member 40, but the invention is not limited thereto. For example, referring to fig. 5 and 6, fig. 5 is a cross-sectional side view of a buckle assembly and a fixing frame according to a second embodiment of the invention, and fig. 6 is a schematic view of the hook member of fig. 5 in a release position.

The structure of the latch assembly 1b of this embodiment is similar to that of the latch assembly 1 of the first embodiment, and the difference is that the first magnetic member and the second magnetic member are disposed at different positions, and the first magnetic member 30b and the second magnetic member 40b of this embodiment are opposite in polarity and attract each other.

Specifically, the first magnetic element 30b of the present embodiment is fixed to the second side plate 120b at a side away from the first side plate 110b, the second magnetic element 40b is fixed to the stop plate 233b of the guiding post 230b, the first magnetic element 30b is located between the second magnetic element 40b and the through hole 111b, and the first magnetic element 30b and the second magnetic element 40b are opposite in opposite polarity and attracted to each other. In this way, the hook member 20b is continuously pushed toward the through hole 111b by the attraction between the first magnetic member 30b and the second magnetic member 40b, and is pushed toward the through hole 111b and located at the locking position.

It should be noted that the present invention is not limited to the position characteristics of the first magnetic element 30b and the second magnetic element 40b, and in other embodiments, as long as the first magnetic element is fixed to the housing, the second magnetic element is fixed to the hook element, the first magnetic element is located between the second magnetic element and the through hole, and the first magnetic element and the second magnetic element are arranged in opposite directions, the effect of enabling the hook element to be located at the fastening position can be achieved by the attraction force between the first magnetic element and the second magnetic element.

According to the fastening assembly of the embodiment, the first magnetic piece is fixed on the shell, and the second magnetic piece is fixed on the fastening piece, so that the fastening piece is located at the fastening position due to the fact that the magnetic force between the first magnetic piece and the second magnetic piece continuously receives the pushing force towards the direction of the through hole, the fastening part penetrates through the through hole of the first side plate and is used for being fastened in the clamping groove of the fixing frame, and the chassis is fixed on the chassis. In addition, the buckle component utilizes the magnetic force to push the clamping hook piece to the buckle position, so that the problem that an elastic piece for providing movable clamping hook pushing force in the prior art is elastically fatigued or even deformed after long-term or frequent use can be solved.

In addition, in some embodiments, the pushing and abutting piece is arranged on the shell, so that a user can conveniently push the clamping hook piece inwards to a release position, and the requirement of unlocking is met. In addition, the design of the pushed inclined plane on the pushed part can change the conduction direction of the force applied to the pushing part, so that the pushing part can be arranged at a position convenient for a user to press, and the case can be detached conveniently.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
