Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

The embodiment is as follows: as shown in fig. 1 to 4, the through-hole locking mechanism of the present embodiment is used for connecting and locking two members having through-holes, and the through-hole locking mechanism includes a first locking member 1, a second locking member 2 and a fastening member 3, where the first locking member 1 is an elongated rod-shaped member, one end of which is provided with a notch extending through the first locking member along its length direction, and the notch extends to an end, the second locking member 2 is an elongated rod-shaped member and is placed in the notch and is rotatably connected to both sides of the notch, the second locking member 2 can rotate around the rotational connection with the notch until one end extends into the notch and is parallel to the first locking member 1 or rotates to be perpendicular to the first locking member 1, and the fastening member 3 is detachably connected to the other end of the first locking member 1 for locking the two members.

As shown in fig. 2, taking the locking between the part a and the part b as an example, the part a has a through hole c, the part b has a through hole d, and of the two parts, a is fixed in position, and b can move freely (or both can move freely), the specific operation process is as follows:

make second retaining member 2 rotate to one end and arrange the breach in completely, make first retaining member 1 and second retaining member 2 constitute a body of rod, afterwards, stretch into the one end at second retaining member 2 place by through-hole department, until second retaining member 2 stretches into part a completely, then, external force makes first retaining member 1 slope in through-hole c down, make first retaining member 1 and second retaining member 2 be the contained angle each other, next, outwards draw first retaining member 2, second retaining member 2 and part an inboard mutual contact extrusion down, can rotate for first retaining member 2, until second retaining member 2 and part an inboard counterbalance, under this state, second retaining member 2 can rotate to being perpendicular with first retaining member 1, next, the other end of first retaining member 1 passes part b's through-hole d, and make part b and part a hug closely, finally, install fastener 3 on the first retaining member 1 other end locking part b and part a can, whole locking mechanical structure reasonable in design, can be under the limited condition in space, make two through-hole parts or equipment fix together, the convenience is convenient.

As shown in fig. 2, the upper end surface of the part a is flat and is provided with a through hole c, the part b can be a plate surface member, when the locking is performed, the first locking member 1 is vertical, under gravity, the second locking member 2 naturally droops to keep one end thereof placed in the gap, and after the second locking member 2 is placed in the part a, the first locking member 1 is slightly inclined to form an included angle with the second locking member 2, and then the first locking member 1 is pulled upwards, so that the operation is very simple.

Preferably, the first locking member 1 is a circular rod-shaped member.

In a preferred embodiment, an extension 21 adapted to the notch is integrally formed at a middle portion of one end of the second locking member 2 along a length direction thereof, and one end of the extension 21, which is close to the second locking member 2, is inserted into the notch and is rotatably connected to both sides of the notch.

In this embodiment, the second locking member 2 is engaged with the notch of the first locking member 1 through the extension portion 21, and the engaging structure is compact.

In a preferred embodiment, through holes are formed at both sides of the notch near an end of the first locking member 1, a fitting hole is formed at an end of the extension portion 21 near the second locking member 2, and a pivot pin is inserted into the through hole and the fitting hole to pivotally connect the extension portion 21 to both sides of the notch.

In this embodiment, the extension 21 does not contact the inner walls of both sides of the notch during actual production, and the damping of the connection with the rotation pin is low, thereby allowing the second securing member 2 to rotate smoothly with respect to the first securing member 1.

At the beginning of the design, the weight of extension 21 should be less than the weight of the cylindrical main body of second retaining member 2 (i.e. the weight except extension 21) to when first retaining member 1 is in vertical state, second retaining member 2 is under the effect of gravity, and the main part is downward all the time, and extension 21 is in the breach all the time, makes things convenient for under the vertical state of whole locking mechanical system in the through-hole to part a.

In a preferred embodiment, the two surfaces of the second locking member 2 corresponding to the two ends of the notch are respectively formed as planes parallel to each other.

In this scheme, also be round bar component under the 2 main part initial conditions of above-mentioned second retaining member, form the plane parallel to each other after its both ends truncation, the diameter of second retaining member 2 is close or equals with the diameter of first retaining member 1, when part an is inboard is hugged closely to second retaining member 2, the plane at its both ends just in time laminates with part an's medial surface, easily whole locking mechanism is firmly locked between two parts, the condition emergence of avoiding locking back easy not hard up (rocking).

In a preferred embodiment, the fastening member 3 is a nut, the first fastening member 1 is provided with a thread on an outer surface thereof, and the fastening member 3 is screwed to an outer portion of the first fastening member 1.

In this scheme, fastener 3 adopts the nut, can directly screw on the body of rod external screw thread of first retaining member 1 to, after part a and part b laminate each other, can directly be in the same place part a and the firm locking of part b through pretension nut.

Preferably, the fastening member 3 is a flat spring washer nut.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
