Slider embodiment one
Referring to fig. 1, there is representatively illustrated a perspective view of a slider in accordance with the present invention. In the exemplary embodiment, the slider proposed by the present invention is explained by taking an example of application to a four-way valve. Those skilled in the art will readily appreciate that various modifications, additions, substitutions, deletions, or other changes may be made to the embodiments described below in order to utilize the concepts of the present invention in other types of valves, and still fall within the scope of the slider concepts set forth herein.
As shown in fig. 1, in the present embodiment, a slider 100 according to the present invention is used for a valve provided in, for example, a four-way valve. The slider 100 includes a body 110 and a hinge pin 120. Referring to fig. 2-3 in conjunction, fig. 2 representatively illustrates an exploded schematic view of a slider 100 which can embody principles of the present invention; a schematic cross-sectional view of a slider 100 that can embody principles of the present invention is representatively illustrated in fig. 3. The structure, connection and functional relationship of the main components of the slider 100 according to the present invention will be described in detail with reference to the above drawings.
As shown in fig. 1 to 3, in the present embodiment, the body 110 of the slider 100 has a slot 111, and two opposite accommodating grooves 112 are formed on the slot wall of the slot 111. The supporting pin 120 has two connecting end portions 121, and the two connecting end portions 121 are respectively locked to the two accommodating grooves 112, so that the supporting pin 120 is disposed at the notch of the slot 111. Through the above structural design, the present invention can arrange the hinge pin 120 inside the slider 100 in a partially embedded manner through the locking and fitting of the hinge pin 120 and the receiving groove 112, thereby optimizing the connection strength of the hinge pin 120 in the slider 100 and avoiding the occurrence of the deformation and loosening phenomenon of the hinge pin 120 under extreme conditions.
Alternatively, in the present embodiment, the surface of the connection end portion 121 of the stay pin 120 may be coated with an anti-slip layer. Accordingly, based on the structural design that the connection end portion 121 of the supporting pin 120 is locked in the accommodating groove 112, the connection end portion 121 coated with the protective layer can be locked with the accommodating groove 112 more stably, and the problem that the supporting pin 120 slips from the accommodating groove 112 is further avoided.
Further, based on the structural design that the surface of the connecting end portion 121 of the supporting pin 120 is covered with the anti-slip layer, in this embodiment, the material of the anti-slip layer may include plastic. In other embodiments, the material of the protective layer may also include other materials, and the friction coefficient of the material relative to the body 110 is greater than the friction coefficient of the hinge pin 120 relative to the body 110.
It should be noted that, based on the structural design that the surface of the connecting end portion 121 of the supporting pin 120 is coated with the anti-slip layer, in the present embodiment, the surface of the other portion of the supporting pin 120 except for the connecting end portion 121 may not be coated with the anti-slip layer, so that the surface of the portions of the supporting pin 120 can maintain a better surface smoothness, thereby reducing the flow resistance of the portions of the supporting pin 120 exposed to the slot 111 to the fluid in the valve when the slider 100 provided by the present invention is applied to a device such as a valve.
Alternatively, as shown in fig. 2, in the present embodiment, the hinge pin 120 has a first surface 122 and a second surface 123, the first surface 122 faces the notch of the slot 111, and the second surface 123 faces away from the notch of the slot 111. On this basis, the first surface 122 may be a plane, and the second surface 123 may be a curved surface. Through the above structure design, one surface of the brace pin 120 can be a curved surface, so that the structural strength of the brace pin 120 is better, and the other surface is a plane, thereby further avoiding the problem that the brace pin 120 rotates and loosens relative to the accommodating groove 112. In other embodiments, the first surface 122 and the second surface 123 of the hinge pin 120 may be other types of surfaces, and are not limited to the present embodiment.
Optionally, in the present embodiment, the body 110 is connected to the connecting end portion 121 of the supporting pin 120 in an over-molding manner, so that the body 110 forms the receiving groove 112 covering the locking connecting end portion 121. Therefore, the cross-sectional shape of the connection end portion 121 of the stay pin 120 matches the shape of the receiving groove 112. Based on the above design, before the slider 100 is molded, the supporting pin 120 may be pre-embedded in the mold of the slider 100, and then the melted material for forming the body 110 is injected, after the material is cooled and molded, the formed body 110 may form the accommodating groove 112 covering the connecting end portion 121 of the supporting pin 120. Therefore, compared with the design that the support pin is directly clamped into the groove of the sliding block in the prior art, the anti-falling structure is equivalently added by adopting the design, so that the connection strength of the support pin 120 and the body 110 is further enhanced, and the anti-falling effect is optimized. Alternatively, as shown in fig. 1 to 3, in the present embodiment, the stay 120 extends substantially along the first direction X, and on this basis, the two connecting end portions 121 of the stay 120 may be respectively located at the two ends of the stay 120 along the first direction X.
Further, as shown in fig. 1 to 3, based on the structural design that the two connecting end portions 121 of the stay pin 120 are respectively located at the two ends of the extending direction of the stay pin 120 (i.e., the first direction X described above), in the present embodiment, the slot 111 of the slider 100 may have two slot walls respectively perpendicular to the first direction X and oppositely arranged. On the basis, the two accommodating grooves 112 may be respectively disposed at the middle positions of the two groove walls along the second direction Y, which is perpendicular to the first direction X.
Second embodiment of the slider
Based on the above detailed description of the first embodiment of the slider proposed by the present invention, a second embodiment of the slider proposed by the present invention will be described below with reference to fig. 4 and 5. Fig. 4 representatively shows an exploded schematic view of a slider in a second embodiment of the present invention, and fig. 5 representatively shows a cross-sectional schematic view of the slider. The slider in the second embodiment has substantially the same design as that of the first embodiment, and the design of the slider in the second embodiment different from that of the first embodiment will be described below.
As shown in fig. 4 and 5, in the present embodiment, the connection end portion 121 of the hinge pin 120 may have a substantially step-like structure, and the connection end portion 121 has a first step 1211 and a second step 1212. Wherein, in the first direction X, the length of the first step 1211 is greater than the length of the second step 1212, and the cavity shape of the receiving groove 112 may match the shape of the stepped structure. On this basis, the connecting end 121 of the hinge pin 120 can be locked in the receiving groove 112 by the first step 1211 and the second step 1212. In other words, when the hinge pin 120 is locked in the receiving cavity 112 through the connecting end portion 121, the first step 1211 and the second step 1212 of the connecting end portion 121 having the step-shaped structure are both locked in the receiving cavity 112. Correspondingly, the groove wall of the receiving groove 112 may also be provided with a step structure matching with the first step 1211 and the second step 1212 of the connecting end portion 121.
Third embodiment of slider
Based on the above detailed description of the first embodiment of the slider proposed by the present invention, a third embodiment of the slider proposed by the present invention will be described below with reference to fig. 6 and 7. Fig. 6 representatively shows an exploded schematic view of a slider in a third embodiment of the present invention, and fig. 7 representatively shows a cross-sectional schematic view of the slider. The slider in the third embodiment has substantially the same design as that of the first embodiment, and the design of the slider in the third embodiment different from that of the first embodiment will be described below.
As shown in fig. 6 and 7, in the present embodiment, the connection end portion 121 of the hinge pin 120 may have a substantially step-like structure, and the connection end portion 121 has a first step 1211 and a second step 1212. Wherein, in the first direction X, the length of the first step 1211 is greater than the length of the second step 1212, and the cavity shape of the receiving groove 112 may match the shape of the first step 1211. In addition, the connecting end 121 of the hinge pin 120 can be locked in the receiving cavity 112 by the first step 1211. In other words, when the hinge pin 120 is locked in the receiving cavity 112 through the connecting end portion 121, the first step 1211 of the connecting end portion 121 having the step-shaped structure is locked in the receiving cavity 112.
As shown in fig. 5 and 7, in the present embodiment, the connecting end portion 121 of the stay pin 120 is designed to have a substantially stepped structure, as compared to the second embodiment. Since the hinge pin 120 is locked in the receiving groove 112 by the first step 1211 of the connection end portion 121 in the present embodiment, the length difference between the first step 1211 and the second step 1212 in the first direction X may be larger in the present embodiment than in the second embodiment.
It should be noted herein that the sliders shown in the drawings and described in the present specification are but a few examples of the many types of sliders that can employ the principles of the present invention. It should be clearly understood that the principles of the present invention are in no way limited to any of the details or any components of the slider shown in the drawings or described in this specification.
