Description

Technical Field

[0001] The utility model relates to the technical field of locking structures, in particular to an eccentric locking structure. Background Art

[0002] When connecting several pipes, a long screw or other object is generally used to penetrate two pipes to connect the two pipes. Although this connection method can ensure the firm strength of the connection between the two adjacent pipes, it is not convenient for operators to perform subsequent disassembly operations. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an eccentric locking structure, which has the effect of greatly facilitating operators to carry out disassembly and assembly operations on a plurality of pipelines.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] An eccentric locking structure, a rotating block installed on a pipe, the rotating block is rotatably connected to the pipe, a screw rod is passed through the rotating block, the screw rod part is located in an adjacent pipe, and the screw rod is threadedly connected to the adjacent pipe;

[0006] The screw rod is driven to move toward the center of the rotating block by rotating the rotating block, and finally two adjacent pipes are brought into contact with each other.

[0007] In a preferred example, the utility model can be further configured as follows: the outer peripheral surface of the rotating block is partially open;

[0008] The interior of the rotating block is cut out by the drum to form a placement space, and the straight line where the central axis of the drum is located is not colinear with the straight line where the central axis of the rotating block is located;

[0009] The interior of the placement space is connected to the interior of the opening, and circular through holes are separately provided on the outer circumferential surface of the rotating block, and the interior of the circular through holes is connected to the interior of the opening;

[0010] The interior of the rotating block is cut off by the drum-shaped object to form an inclined surface;

[0011] The inclined surface and the opening form a sideline, and the shortest distance from a point on the sideline to the straight line where the central axis of the rotating block is located is recorded as L1. The closer to the circular through hole, the smaller the length of L1.

[0012] In a preferred example, the utility model can be further configured as follows: the diameter of the circular through hole is 1.2-1.4 times the opening width.

[0013] In a preferred example, the utility model can be further configured as follows: a connection seat is provided at one end of the screw rod located inside the rotating block, the cross section of the connection seat is circular, and the cross section diameter of the connection seat is smaller than the diameter of the circular through hole but larger than the opening width;

[0014] The shape of the connecting seat and the surface in contact with the inclined surface are in close contact.

[0015] In a preferred example, the utility model can be further configured as follows: a rotating handle is integrally provided on one side of the rotating block away from the central axis of the pipeline.

[0016] In summary, the present invention includes at least one of the following beneficial technical effects:

[0017] 1. A rotating block is arranged on the pipeline, and a screw is arranged on the rotating block. The screw part enters into the adjacent pipeline. The rotating block is rotated to drive the screw to move, so that the two adjacent pipelines are contacted and the positions of the two pipelines are fixed, which greatly facilitates the operator to disassemble and assemble several pipelines.

[0018] 2. By matching the shape of the upper half of the connecting seat with the inclined surface, the contact area between the connecting seat and the inclined surface is increased, ensuring that the connecting seat can be quickly driven to move when the rotating block rotates, and secondly, the friction between the inclined surface and the connecting seat is increased.

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1-Figure 5 As shown, the utility model discloses an eccentric locking structure, the locking structure is installed on the pipeline, and three locking structures are installed on each pipeline.

[0028] The locking structure comprises a rotating block 1 mounted on the pipeline. The rotating block 1 is rotatably connected to the pipeline. A rotating handle 5 is integrally provided on one side of the rotating block 1 away from the central axis of the pipeline. The rotating handle 5 is located outside the pipeline.

[0029] The outer peripheral surface of the rotating block 1 is partially open, and the interior of the rotating block 1 is cut off by the drum to form a placement space 2, and the straight line where the central axis of the drum is located is not colinear with the straight line where the central axis of the rotating block 1 is located. The interior of the placement space 2 is connected to the interior of the opening. The interior of the rotating block 1 is cut off by the drum to form an inclined surface 22.

[0030] The inclined surface 22 intersects with the opening to form a sideline 3. The shortest distance from a point on the sideline 3 to the straight line where the central axis of the rotating block 1 is located is recorded as L1, and the closer to the circular through hole 21, the smaller the length of L1.

[0031] The outer circumference of the rotating block 1 is provided with circular through holes 21, the inside of which is connected to the inside of the opening. The diameter of the circular through hole 21 is 1.2-1.4 times the width of the opening. In this embodiment, the diameter of the circular through hole is 1.3 times the width of the opening.

[0032] The rotating block 1 is provided with a screw 11, which is partially located in the adjacent pipes and is threadedly connected to the adjacent pipes. Rotating the rotating block 1 drives the screw 11 to move toward the center of the rotating block 1, and finally makes the two adjacent pipes contact.

[0033] The end of the screw rod 11 located inside the rotating block 1 is provided with a connecting seat 4, the cross section of which is circular, the cross section diameter of which is smaller than the diameter of the circular through hole 21 but larger than the opening width. The shape of the side of the connecting seat 4 that contacts the inclined surface 22 is in close contact with each other.

[0034] The implementation principle of the above embodiment is:

[0035] The operator first screws three screws 11 partially into the bottom of another pipe.

[0036] Then, the three screw rods 11 are placed into the corresponding rotating blocks 1. The connecting seat 4 passes through the circular through hole 21 and enters into the placement space 2.

[0037] The operator uses a tool to rotate the rotating handle 5 , the rotating handle 5 drives the rotating block 1 to rotate, the rotating block 1 drives the inclined surface 22 to rotate, and the inclined surface 22 begins to contact with the upper half of the connecting seat 4 .

[0038] As the rotating block 1 rotates, the inclined surface 22 drives the connecting seat 4 to start moving downward, the connecting seat 4 drives the screw rod 11 to move downward, and the screw rod 11 drives the pipe connected thereto to move downward.

[0039] When one end of the two pipes touches, the operator stops turning.

[0040] It is particularly noted that attention should be paid to the length of the reserved portion of the screw rod 11 on the pipe. This length ensures that the connecting seat 4 at the bottom of the screw rod 11 can enter the placement space 2.

[0041] In addition, when the two pipes are in contact, due to the friction between the connecting seat 4 and the inclined surface 22 and other reasons, the rotating block 1 cannot rotate without the application of external force.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
