Description

Technical Field

[0001] The present invention relates to the technical field of communication equipment, and in particular to a clamp and a fiber distribution box and a use method thereof. Background Art

[0002] The fiber splitter box is a widely used device in the communication field, which is used to connect the trunk optical cable and the distribution optical cable. When the fiber splitter box is installed outdoors, it is mostly fixed on a rod-shaped support by a clamp. The clamp structure currently used is as follows: Figure 1 As shown, it usually includes two semicircular connectors 1-1 that can be connected, and each connector 1-1 is provided with a straight section 1-2 at both ends. After the two connectors 1-1 are connected, a bolt assembly 1-3 is arranged on the straight section 1-2, so that the two connectors 1-1 are embraced on the rod-shaped support body. In actual use, the clamp is usually connected to other connecting parts on the connector 1-1, so as to facilitate fixing other cables and the like that need to be fixed on the rod-shaped support body. When installing the clamp, the embracing diameter of the two connectors 1-1 is usually smaller than the diameter of the rod-shaped support body. After tightening the bolt assembly 1-3, the two connectors 1-1 are tightly embraced on the rod-shaped support body. In this state, the rod-shaped support body has a large outward force on the two connectors 1-1. In addition, in order to facilitate the screwing of the bolt assembly 1-3, the junction of the connector 1-1 and the straight section 1-2 has a certain distance from the bolt assembly 1-3. Therefore, it is easy to make this part appear as shown in the figure. Figure 2 The deformation shown in the figure makes the embracing diameter of the two connectors 1-1 larger, which seriously affects the stability of the clamp on the rod-shaped support body, and further affects the stability of the fiber distribution box. In order to solve this problem, a commonly used method at this stage is to set a reinforcing rib 1-4 at the connection between the straight section 1-2 and the connector, such as Figure 3 As shown, however, the clamp of this structure is very inconvenient to use tools to screw the bolt assembly in actual use. Summary of the invention

[0003] The purpose of the present invention is to avoid the deficiencies of the prior art and to provide a clamp and a fiber splitter box and a use method, thereby effectively solving the deficiencies in the prior art.

When the first connecting member and the second connecting member approach each other, the first connecting end and the second connecting end are tightened, and when the first connecting member and the second connecting member move away from each other, the first connecting end and the second connecting end are loosened.

[0014] Furthermore, the first connecting member and the second connecting member are threadedly engaged with each other.

[0015] Furthermore, the first connecting member and the second connecting member are interference fit.

[0016] Furthermore, the first connecting end includes a first connecting portion and a second connecting portion, and a through groove adapted to the second connecting end is formed between the first connecting portion and the second connecting portion.

[0017] Furthermore, the taper direction of the first connecting portion and the taper direction of the second connecting portion are the same or opposite.

[0041] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0042] In the description of the present invention, unless otherwise specified, "multiple" means two or more than two; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] like Figure 4-13As shown, a hoop described in this embodiment includes two embracing bodies 1, both ends of the embracing bodies 1 are provided with connecting bodies 2, and the connecting bodies 2 are connected by a locking member, under the action of the locking member, the two embracing bodies 1 are embraced and docked, specifically, the locking member can be a bolt assembly (not shown in the figure), the two ends of the embracing body 1 are respectively provided with a first connecting end 4 and a second connecting end 5, the first connecting end 4 and the second connecting end 5 are respectively arranged at the two ends of the embracing body 1, and the connecting body 2 at one end is connected to one end of the embracing body 1 through the first connecting end 4, and the other end The connector 2 is connected to the other end of the embracing body 1 through the second connecting end 5, and also includes a tensioning member 6, which is used to connect the first connecting end 4 and the second connecting end 5. When the two embracing bodies 1 are docked and embraced, the first connecting end 4 and the second connecting end 5 can be partially misaligned and matched. The tensioning member 6 cooperates with the first connecting end 4 and the second connecting end 5 respectively to tighten the two ends of the embracing body 1, so that the cooperation of the two embracing bodies 1 is more secure, and the joint of the connector 2 and the embracing body 1 will not be deformed, which effectively prevents the embracing diameter of the two embracing bodies 1 from becoming larger.

[0044] Specifically, the first connection end 4 and the second connection end 5 are both arc-shaped, the end of the embracing body 1 is extended a portion and then bent in the reverse direction, and then connected to the end of the connecting body 2 close to the embracing body 1, so the first connection end 4 and the second connection end 5 are partially extended out of the embracing body 1, when the two embracing bodies 1 are butt-jointed and embraced, the first connection end 4 at one end of one embracing body 1 cooperates with the second connection end 5 at the corresponding end of the other embracing body 1, and the first connection end 4 and the second connection end 5 partially cross and overlap to form a channel structure 7, as shown Figure 7 As shown, the channel structure 7 can be adapted to the tensioning member 6, and can further pull its first connection end 4 toward the direction of the other embracing body 1, and at the same time pull the second connection end 5 toward the direction of the other embracing body 1, thereby directly applying tension to the two ends of the embracing body 1. In this state, when the embracing body 1 is clamped on the rod-shaped support, for the same embracing body 1, the direction of the force of the tensioning member 6 on the first connection end 4 (the second connection end 5) is in one direction, and the reasonable directions of the force of the embracing body 1 on the first connection end 4 (the second connection end 5) and the force of the connector 2 on the first connection end 4 (the second connection end 5) are opposite to the previous direction, so that the embracing body 1 is in a tensioned state, and the connection between the embracing body 1 and the connector 2 will not occur as Figure 2 The deformation shown can effectively prevent the embracing diameter of the embracing body 1 from becoming larger, thereby greatly increasing the installation stability of the present invention.

[0045] More specifically, the cross-sectional areas of the two ends of the channel structure 7 are different, and the channel structure 7 forms a virtual cone. Correspondingly, the tensioning member 6 is also cone-shaped. In one embodiment, Fig.11 , Fig.12As shown, the tensioning member 6 can be an integral conical member 8, and the outer surface of the conical member 8 is provided with a thread. By screwing the conical member 8 into the above-mentioned channel structure 7, the first connecting end 4 and the second connecting end 5 are tightened in two directions respectively under the mutual extrusion of the conical surfaces. In another embodiment, the tensioning member 6 includes a first connecting member and a second connecting member, and the first connecting member and the second connecting member can be separated from each other or approached to each other. When the two are close to each other, the first connecting end 4 and the second connecting end 5 are pulled toward both sides respectively. When the first connecting member and the second connecting member are separated from each other, the first connecting end 4 and the second connecting end 5 are loosened.

[0046] More specifically, the first connection end 4 includes a first connection part 9 and a second connection part 10, and a through groove adapted to the second connection end 5 is formed between the first connection part 9 and the second connection part 10. When the two embracing bodies 1 are docked and embraced, the second connection end 5 can pass through the through groove and cooperate with the first connection part 9 and the second connection part 10 to form a channel structure 7.

[0047] In this embodiment, the first connecting member and the second connecting member can be connected by threaded fit or interference fit. Specifically, Figure 4-6 As shown, the taper direction of the first connection part 9 and the taper direction of the second connection part 10 can be the same, the first connection part 9, the second connection end 5 and the second connection part 10 are in a virtual cone shape, the first connection member can be a tapered section 11, the second connection member is a tension bolt 12, the end of the tapered section 11 with a smaller diameter is provided with a hole adapted to the tension bolt 12, the tapered section 11 is inserted from the end of the channel structure 7 with a larger diameter, and then the tension bolt 12 is inserted from the end of the channel structure 7 with a smaller diameter, and the tension bolt 12 is made to 2 and the holes on the tapered section 11 cooperate so that the tightening bolt 12 is against the outside of the first connecting part 9. While tightening, the tapered section 11 continues to extend into the channel structure 7 and cooperates with the first connecting part 9, the second connecting part 10, and the second connecting end 5 respectively, thereby pushing the second connecting end 5 toward one side and pushing the first connecting part 9 and the second connecting part 10 toward the other side to tighten the two ends of the embracing body 1. The tightening bolt 12 can be a bare rod bolt, and the bare rod bolt and the hole on the tapered section 11 have an interference fit, which is more convenient to install.

[0048] In another embodiment, if Figure 8-10As shown, the taper directions of the first connection part 9 and the second connection part 10 are opposite, that is, the first connection part 9 and the second connection part 10 are symmetrically arranged, and the end with a larger diameter of the first connection part 9 and the end with a larger diameter of the second connection part 10 are both facing outward. In this embodiment, the first connection member is a main cone section 13, and the second connection member is a secondary cone section 14. The end with a smaller diameter of the main cone section 13 is provided with a mounting hole 15, and the end with a larger diameter of the secondary cone section 14 is provided with a connecting rod 16. The connecting rod 16 and the mounting hole 15 can be threaded or interference fit. The end with a smaller diameter of the main cone section 13 is inserted by the outer end of the first connection part 9, and the end with a smaller diameter of the secondary cone section 14 is inserted by the outer end of the second connection part 10. A part of the main cone section 13 cooperates with the second connection end 5, and a part of the secondary cone section 14 cooperates with the second connection end 5, thereby pushing the second connection end 5 toward one side and pushing the first connection part 9 and the second connection part 10 toward the other side.

[0049] Specifically, notches or cut edges are provided on the cone 8, the cone section 11, the tension bolt 12, the main cone section 13 and the auxiliary cone section 14 to facilitate screwing by a tool.

[0050] In another embodiment, if Fig.13 As shown, the first connection end 4 and the second connection end 5 are respectively close to different sides of the embracing body 1. When the two embracing bodies 1 are docked and embraced, the first connection end 4 and the second connection end 5 are staggered with each other. In this embodiment, the adaptation of the first connection end 4 and the second connection end 5 is more convenient, which is conducive to improving the installation efficiency.

[0051] like Figure 14-16As shown, the fiber splitting box described in this embodiment includes a fiber splitting box body, which is connected to one of the two embracing bodies 1, and the fiber splitting box body is provided with a connecting structure for convenient connection in cooperation with the embracing body 1. Specifically, the fiber splitting box body includes a containing box body 1-10 and a cover 1-11, and the containing box body 1-10 and the cover 1-11 are hinged to each other, and the connecting structure is arranged on the back of the containing box body 1-10, that is, the connecting structure is arranged on the side of the containing box body 1-10 away from the cover 1-11. On one side, more specifically, the connecting structure protrudes from the back of the accommodating box 1-10, so that there is a certain distance between the encircling body 1 and the accommodating box 1-10, and the operator tightens the two encircling bodies 1. The connecting structure can be a fixing seat 1-12 protruding from the back of the accommodating box 1-10, and the fixing seat 1-12 is connected to the encircling body 1, and the fixing seat 1-12 is provided with an arc receiving groove 1-13 that matches the shape of the encircling body 1, increasing the distance between the fixing seat 1-12 and the encircling body 1. The contact area between the two sides increases the connection strength between the embracing body 1 and the containing box 1-10, and improves the stability of the present invention. More specifically, the fixing seat 1-12 can be a portal frame structure. In this embodiment, the portal frame structure includes an arc portion 1-14, and the arc portion 1-14 is arranged in an arc shape to form an arc receiving groove 1-13 adapted to the embracing body 1, so that the arc portion 1-14 can fit on the embracing body 1. The arc portion 1-14 and the embracing body 1 can also be connected by a rivet or bolt assembly, or welded. In this embodiment, a connecting hole structure is provided on the embracing body 1 connected to the containing box 1-10 to facilitate the passage of the rivet or bolt assembly so as to be connected with the arc portion 1-14. The connecting hole structure is not shown in the figure. In practice, the specific number and position of the connecting hole structure are determined according to the situation. Straight portions 1-15 are respectively provided at both ends of the arc portion 1-14, and the straight portion 1-15 is connected to the containing box 1-10.

[0052] In this embodiment, the number of fixing seats 1-12 on the accommodating box 1-10 is preferably two, and the two fixing seats 1-12 are aligned vertically so as to provide two sets of upper and lower clamps to increase the connection strength between the rod-shaped supports.

[0053] Usually when installing the clamp, the embracing diameter of the clamp is mostly equivalent to the diameter of the rod-shaped support. Usually, the diameter of the two parts of the clamp after they are fully connected is slightly smaller than the diameter of the rod-shaped support, which makes installation more convenient. After the two parts of the clamp are connected and embraced on the rod-shaped support, there is a certain gap between the two ends of the clamp, and the size of the gap is generally 2-10 mm. Then, the bolt assembly is used to tighten the two ends of the clamp so that the two ends of the two parts are in contact or the distance is reduced to about 2 mm. Therefore, the method of using the present invention is as follows: during specific installation, the distribution box body is aligned, and when the fiber distribution box body is aligned, the two embracing bodies 1 are embraced on the rod-shaped support, and the connecting bodies 2 at both ends are connected by locking pieces so that the embracing body 1 does not fall off the rod-shaped support. At this time, the first connecting end 4 and the second connecting end 5 are staggered to form a virtual cone-shaped channel structure 7. In this state, the first connecting end 4 and the second connecting end 5 are partially staggered to form a virtual cone-shaped channel structure 7. In this state, the first connecting end 4 and the second connecting end 5 are partially staggered, and the two embracing bodies 1 and the rod-shaped support are not completely Tighten, then adapt the first connecting member and the second connecting member to the two ends of the channel structure 7 respectively, and make the first connecting member and the second connecting member tighten each other, and then tighten the first connecting end 4 and the second connecting end 5, and then further lock the connecting body 2 at both ends of the encircling body 1 through the locking member, the first connecting member, the second connecting member and the locking member cooperate, so that the encircling body 1 is tightly encircled on the rod-shaped support, so the present invention, during the entire installation process, first makes the first connecting end 4 and the second connecting end 5 partially overlap and cooperate, at this time there is still a certain tightening margin between the first connecting end 4 and the second connecting end 5 and the corresponding two connecting bodies 2, after the tensioning member 6 and the first connecting end 4 and the second connecting end 5 are matched, then the corresponding two connecting bodies 2 are completely tightened, the first connecting member and the second connecting member are completely tightened, the first connecting end 4 and the second connecting end 5 are completely tightened, and then the two ends of the encircling body 1 are completely tightened to prevent deformation at the connection between the encircling body 1 and the connecting body 2.

[0054] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
