Description

Technical Field

[0001] The present application relates to the technical field of fasteners for electrical pipelines, and in particular to a quick-installation pipe clamp. Background Art

[0002] The published text of the Chinese invention application entitled "Structural Fastener" with publication number CN111102399A discloses a technical solution for hanging and fastening electrical conduits. The invention application entitled "Supporting pipe clamp comprising a worm gear for accommodating various pipe sizes" with publication number TW202307356A discloses the common structural form of this type of pipe clamp. The published text of the U.S. patent application entitled "Support system for pipes and other loads" with publication number US4961553A provides a similar method of hanging and installing electrical conduits. The above prior art explains one of the common installation forms of electrical conduits and the common structure of the pipe clamp used when installing electrical conduits. It is recorded here for reference. The following is a brief description of the technical background related to this application in the prior art.

[0003] For the installation of electrical conduits, please refer to Figure 1 Schematic diagram of. In order to facilitate the installation and adjustment of the wire tube 2, the wire tube 2 is usually not fixed directly on the ceiling, but is suspended in the installation groove 3 fixed on the ceiling through the pipe clamp 1. The pipe clamp 1 is a U-shaped clamp formed by two mounting frames 11 butted at one end, and the wire tube 2 passes through the U-shaped area of ​​the pipe clamp 1. On the one hand, it is easy to adjust to different directions of the pipeline, and on the other hand, it can also simplify the installation process of the wire tube 2.

[0004] Figure 2 It is a structural diagram of a pipe clamp 1 in the prior art. The upper end of the mounting frame 11 is suspended in the mounting groove 3, and the lower end is connected to another mounting frame by fasteners or mutually cooperating snap-fit ​​structures. The lower opening 32 of the mounting groove 3 is retracted, such as the inwardly folded flange shape shown in the figure. In order to be suspended in the mounting groove 3, the upper end of the mounting frame 11 is respectively formed with an expansion portion 11D and a contraction portion 11E from top to bottom. Along the cross-sectional width direction of the mounting groove 3, the width of the expansion portion 11D is greater than the width of the lower opening of the mounting groove 3, and the width of the contraction portion 11E is less than the width of the lower opening of the mounting groove 3. For this reason, when the pipe clamp 1 is placed in the mounting groove 3 in the manner shown in the figure, it is obvious that the lower opening of the mounting frame 11 blocks the fall of the expansion portion 11D, thereby realizing the hanging function of the mounting frame 11 on the mounting groove 3.

[0005] The inconveniences of similar pipe clamps are obvious. The presence of the expansion part 11D of the mounting bracket 11 makes it impossible to place the mounting bracket 11 into the mounting groove 3 in the hanging posture. Instead, it needs to be inserted from the end of the mounting groove 3 and moved to the corresponding position. This is not only extremely inconvenient, but also may be impossible when other pipe clamps 1 are pre-installed on the mounting groove 3. Therefore, most of the time, it is necessary to take a single mounting bracket 11 as a unit and rotate it by a certain angle around the up-down direction to deflect the mounting bracket 11 in the length direction of the mounting groove 3 so that it can be inserted into the mounting groove 3. However, when two mounting brackets 11 are assembled into a pipe clamp 1, it cannot be put into the mounting groove 3. Such an installation process is complex and not convenient for actual operation.

Detailed implementation manners

[0031] The technical solutions of the present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments. In this specification, the dimensions of the drawings do not represent the actual size ratio. The drawings are only used to reflect the relative positional relationship and connection relationship between components. Components with the same name or the same reference numeral represent similar or the same structures, and are only for illustrative purposes.

[0032] The pipe clamp 1 of the present application mainly realizes the effect of being inserted directly into the mounting groove 3 without changing its rotation direction, so as to achieve the purpose of simplifying the installation process. Figure 3 Schematic diagram of one solution of the pipe clamp 1. Figure 4 Based on Figure 3 Schematic diagram of the installation method of the wire pipe 2 of the pipe clamp 1.

[0033] Taking Figure 3For example, the pipe clamp 1 has a supporting body 13, and a penetration space 12 for the wire tube 2 to be penetrated is formed on the supporting body 13. Usually, the penetration space is U-shaped. A suspension point 131 is formed on both sides of the penetration space 12 on the supporting body 13, that is, two suspension points 131 belonging to both sides of the penetration space 12 are formed, and two hanging ears 113 are arranged oppositely on each hanging point 131. Therefore, the system formed by the two hanging ears 113 can be divided into a relative outer side and a relative inner side. For one of the hanging ears 113, the relative outer side refers to the side away from the other hanging ear 113, and the relative inner side refers to the side facing the other hanging ear 113.

[0034] The hook 113 has a hook 114 extending away from the hanging point 131. The two hooks 113 are relatively movable. On this basis, the hooks 114 of the two hooks 113 are located on the relative outside of each other. The two hooks 113 also form a chamfered structure 115 located on the outside at the end where the hook 114 is located, which is used to guide and drive the hook 114 of the movable hook 113 to move relatively inward during insertion to achieve the purpose of entering the installation groove 3. Here, it is only required that the two hooks 113 are relatively movable, and it is not necessary to require that the two hooks 113 are movable relative to the supporting body 13. The hook 114 has a contraction portion 11E and an expansion portion 11D. The contraction portion 11E is formed by removing material from the relative outside near the end of the hook 113, and the expansion portion 11D is a protrusion formed on one side of the end of the contraction portion 11E and protruding to the relative outside compared with the contraction portion 11E.

[0035] refer to Figure 4 The installation flow chart shows that the movable setting of the hanging ear 113 is mainly to make the relative distance between the two hooks 114 variable, so as to achieve the purpose of direct insertion installation. Specifically, in the process of inserting the pipe clamp 1 into the installation slot 3 with the hanging point 131 facing the installation slot 3, the chamfered structure 115 first contacts the opening edge 31 of the installation slot 3. The chamfered structure 115 is squeezed by the opening edge 31 so that the hook 114 of the movable hanging ear 113 deviates to the relative inner side, so that the distance between the expansion parts 11D of the hooks 114 of the two hanging ears 113 is less than or equal to the retracted opening of the installation slot 3, so as to achieve the purpose of insertion. After the hook 114 is inserted into the installation slot 3, since the retracted opening of the installation slot 3 no longer squeezes the expansion part 11D, the hook 114 is reset, and the retracted opening edge 31 of the installation slot 3 enters the contraction part 11E of the hook 114 and supports the expansion part 11D, so as to achieve the purpose of hanging the pipe clamp 1. In line with this purpose, the hanging ear 113 can be configured to have a reset function based on the movable setting, that is, after deviating from the corresponding position under the action of external force, it will reset to the original position if the corresponding external force is lost. The reset function can be achieved by a corresponding elastic component.

[0036] like Figure 5, the supporting body 13 may be formed by connecting two mounting frames 11. The supporting body 13 may include two mounting frames 11 arranged opposite to each other, one end of the mounting frame 11 is a connecting end 111, and the other end is a hanging end 112. When in use, the two mounting frames 11 arranged opposite to each other are butted against each other at the connecting end 111, and the hanging ends 112 of the two mounting frames 11 point to the same side, so that the two mounting frames 11 are combined into a penetration space 12. The way in which the connecting ends 111 are butted against each other may be a shaft connection, a fastener connection, a snap-fit ​​structure connection, or other structures for interconnection that have been used in the prior art. The drawings of the present application only show examples of fastener connections. In this case, the size of the penetration space 12 can be changed by placing gaskets of different thicknesses between the connecting ends 111 of the two mounting frames 11 to adapt to wire tubes 2 of different sizes. Alternatively, the wire tube 2 is clamped by tightening fasteners such as screws, and wire tubes of different diameters are adapted to pipe clamps of different sizes. In the actual product development process, the mounting frame 11 and the two hanging ears 113 arranged thereon are usually arranged in one piece, and the whole can exist as an independent connecting piece 126 product. When used, it is only necessary to connect the connecting ends 111 of the mounting frame 11 of the two sets of connecting pieces 126 to be installed through the corresponding connecting means to form the pipe clamp 1 with the hanging points 131 on both sides.

[0037] Figure 9 , 10 FIG. 1 is a schematic diagram of another embodiment of a pipe clamp 1 formed by combining two connecting members 126, wherein the two connecting members 126 are engaged with each other in the installed state through the buckle structure of the respective mounting frames 11 at the connecting ends 111, so that the wire pipe 2 can be fixed when it is suspended. Figure 9 As shown, a slot 141 and a foot 142 are respectively formed on the connecting ends 111 of the two mounting frames 11 connected to each other, wherein the slot 141 is a through slot formed at the connecting end 111 and passing through both sides thereof, and generally extends along the width direction of the connecting end 111. The foot 142 is an extended member of a certain width formed at the connecting end 111, and this member usually has a bend that is not parallel to the opening direction of the slot 141 in the installed state. The width of the slot 141 is adapted to the width of the foot 142, so in the installed state, after the positions of the two connecting ends 111 are determined, due to the existence of the bend of the foot 142, the buckling structure formed by the foot 142 and the slot 141 is effective, thereby combining the two connecting members 126 into a whole that can bear the force to suspend the wire tube 2.

[0038] The insertion space 12 is used for inserting the wire tube 2. For the mounting frame 11, two hanging ears 113 are arranged opposite to each other at the hanging end 112, so the system formed by the two hanging ears 113 can be divided into a relatively outer side and a relatively inner side. For one of the hanging ears 113, the relatively outer side refers to the side away from the other hanging ear 113, and the relatively inner side refers to the side facing the other hanging ear 113.

[0039] Figure 5 In one embodiment, both the two hanging ears 113 are rotatably arranged on the mounting frame 11, one end of the hanging ear 113 is rotatably arranged around the pivot O arranged on the mounting frame 11, and the other end is a free end, and a hook 114 and a chamfered structure 115 at the end are formed on the free end. The hanging ear 113 is driven by an elastic component 116 to achieve reset. In actual applications, the pivot O is a riveted shaft. The elastic component 116 can be directly connected between the two hanging ears 113 or can be connected to the hanging ears 113 and the mounting frame 11 respectively to achieve elastic reset of the hanging ears 113.

[0040] Preferably, a limiting structure 124 may be formed between the mounting frame 11 and the hanging ear 113, and the limiting structure 124 is a limiting groove 241 and a limiting protrusion 242 that moves in a limited manner in the limiting groove 241, wherein one of the limiting groove 241 and the limiting protrusion 242 is formed on the mounting frame 11, and the other is formed on the hanging ear 113. Since the limiting groove 241 limits the range of motion of the limiting protrusion 242, the range of motion of the hanging ear 113 on the mounting frame 11 is also limited, regardless of whether the hanging ear 113 is connected to the mounting frame 11 by rotation, movement, or other connection methods.

[0041] exist Figure 5 In the embodiment, the elastic component 116 is a spring 119 whose two ends are respectively connected to the two ears 113. More specifically, the two ends of the spring 119 are respectively connected to the hooks 114 of the ears 113, and the spring 119 is compressed when the distance between the two hooks 114 becomes smaller, thereby providing the elastic force required for the hook 114 to reset. In order to orient the deformation direction of the spring 119, the spring 119 is preferably V-shaped, with its two ends respectively connected to the ears 113, and the middle part passes through the limiting ring 120 on the surface of the mounting frame 11. The first function of the limiting ring 120 is to limit the range of movement of the spring 119, so that the spring 119 deforms in a specific direction when compressed, and the second function is to limit the movement distance of the spring 119 along the preset deformation direction, that is, to limit the spring 119 to move only between the first limit position A and the second limit position B of the limiting ring 120. The movement range also corresponds to the range of variation of the distance between the two ears 113, which partially achieves the purpose of limiting the range of movement of the ears 113.

[0042] A more specific spring 119 has a guiding section 121 at the vertex of the V shape, which serves to evenly distribute the displacement amounts of the two lugs 113, such that the hooks 114 at both ends are evenly pushed away from their original positions. The guiding section 121 forms a receiving area for accommodating the limiting ring 120. The receiving area 122 can be nearly rectangular or nearly elliptical to provide a nearly rectangular space with a large aspect ratio. When the limiting ring 120 moves upward within this receiving area, since the gaps between the guiding sections 121 on both sides of the limiting ring 120 and the limiting ring 120 are limited, the V-shaped vertex of the spring 119 can be restricted near the limiting ring 120 to a certain extent, which also means that the spring displacement amounts distributed to the hooks 114 on both the left and right sides of the limiting ring 120 are approximately the same. On this basis, a receiving opening area 123 can be formed at the end of the guiding section 121. The space width of the receiving opening area 123 is smaller than the space width at the strip-shaped area 122, and its purpose is to prevent the limiting ring 120 from leaving the receiving area 122. This does not require the width of the receiving opening area 123 to be smaller than the width of the limiting ring 120, but only needs to ensure that the width of the receiving opening area 123 is smaller than the width of the receiving area 122. Because when the spring is deflected under force, due to the action of the lateral force, one of the guiding sections 121 is always in contact with the limiting ring 120, so a slight constriction can also play a role in restricting the limiting ring 120 from escaping from the receiving area 122.

[0043] As Figure 6 shown in the embodiment of, the setting manner of the elastic member 116 is not unique. Figure 6 The technical solution of respectively arranging the elastic members 116 on each lug 113 is given. Figure 6 This is one of the embodiments. The elastic member 116 is a snap ring 125 wound around the pivot O. One end of the snap ring 125 abuts against the supporting body 13, and the other end abuts against the lug 113. Then, the reset function of the lug 113 can be realized by relying on the snap ring 125.

[0044] Actually, in order to realize the insertion of the pipe clamp 1, it is only required that the distance between the hooks 114 of the two lugs 113 can be compressed, and it is not necessary that both lugs 113 are movably arranged. Figure 7 For another embodiment, one of the lugs 113 can be fixedly arranged at the hanging end 112 of the mounting bracket 11, such as being directly integrally formed with the mounting bracket 11 by stamping. The other lug 113 can be movably arranged on the mounting bracket 11 and is arranged opposite to the fixed lug 113.

[0045] As Figure 8In the embodiment, in order to realize the relative retraction of the hooks 114 of the two hanging ears 113 to reduce the distance between the two, its essence is that the position of the hook 114 needs to float in the relative direction between the two. For this, the hanging ears 113 do not need to be rotated, and the hanging ears 113 can also be moved at the hanging end 112 of the mounting frame 11. Specifically, it is only necessary to meet the requirement that the two hanging ears 113 can move toward each other at the hanging end 112. Therefore, at least one of the two hanging ears 113 can be configured to move toward each other at the hanging end 112 to achieve this purpose. Specifically, for example, a first folded edge 117 of a U shape or other shape is provided at the hanging end 112 along the arrangement direction of the two hanging ears 113, and a second folded edge 118 cooperating with the first folded edge 117 is provided at the root of the hanging ear 113. The first folded edge 117 is engaged with the second folded edge 118, and can slide along the direction in which the first folded edge 117 extends, so that the relative sliding between the hanging ears 113 can be achieved.

[0046] like Figure 9 In an embodiment, the pipe clamp 1 may also have a supporting body 13, on which a space 12 for the wire tube 2 to pass is formed. Specifically, it may be formed only by a bent mounting frame 11. The supporting body 13 only needs to be provided with one suspension point 131, at which two hanging ears 113 are relatively provided, so that the system formed by the two hanging ears 113 can be divided into a relative outer side and a relative inner side. For one of the hanging ears 113, the relative outer side refers to the side away from the other hanging ear 113, and the relative inner side refers to the side facing the other hanging ear 113. As shown in the figure, the structure between the two hanging ears 113 can follow the design in the above embodiment. It seems that in the case of a single hanging point 131, there is no need to consider the rotation direction during installation, so it seems unnecessary to set up a corresponding hanging mechanism with two hanging ears 113. However, it should be noted that in most cases, due to the influence of the pre-positioning of the wire tube 2, even if only a single hanging point 131 is set, the rotation direction of the pipe clamp 1 cannot be changed during the insertion process due to the limitation of the wire tube 2. Therefore, it is still necessary to achieve the effect of installing the pipe clamp 1 into the installation groove 3 by direct insertion without changing its rotation direction through the technical solution of the present application.

[0047] The above content only describes the preferred implementation mode of the present application, and does not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements made to the technical solution of the present application by ordinary technicians in this field should fall within the protection scope determined by the claims of the present application.
