Abstract

The invention relates to a limiting split type connecting key, and belongs to the technical field of mechanical connecting keys. The clamping device comprises a clamping part and an inserting part, wherein the clamping part is composed of two opposite semi-cylinders with the front ends connected, a gap for accommodating the inserting part is formed between the semi-cylinders, the side walls of the semi-cylinders are also provided with vertically outward protruding parts, the inserting part can be inserted into the clamping part and clamped, and the distance between the two semi-cylinders is increased. Compared with the original integrated butterfly-shaped connecting key, the problem that the honeycomb restraining system is easy to rotate and fall off is solved, and meanwhile, the honeycomb restraining system can be used for pre-installation, so that the laying time of the honeycomb restraining system is shortened. The connection mode that the syntropy set up only needs just can accomplish the operation in adapting unit's one side, and the installation time that has significantly reduced and to installation space's requirement, lets the connection operation more convenient, and the stability of connecting is higher.

Description

Spacing split type connecting key
Technical Field
The invention relates to a limiting split type connecting key, and belongs to the technical field of mechanical connecting keys.
Background
The limiting split type connecting key is used for connecting two parts and limiting the position, and the limiting split type connecting key is used for a honeycomb restraint system and is used for upgrading the structure of the previous generation of integrated butterfly type connecting key. Integral type butterfly type connection key inserts through oval through-hole when using, then rotatory 90 spacing chucking reaches the effect of connecting parts among the honeycomb restraint system, but when the use, often because of the influence of filler, leads to integral type butterfly type connection key chucking back to rotate again, breaks away from the screens, drops from oval through-hole once more, loses connection function.
Disclosure of Invention
The invention aims to solve the problems in the prior art and further provides a limiting split type connecting key.
The purpose of the invention is realized by the following technical scheme:
the utility model provides a spacing split type connection key, includes joint portion and insertion portion, its characterized in that, joint portion comprises the relative halfcylinder that two front ends are connected, have the space that holds insertion portion between the halfcylinder, the halfcylinder lateral wall still has perpendicular outside bulge, insertion portion can insert joint portion and chucking, increases the distance between two halfcylinders simultaneously.
Further, the insertion portion is t-shaped.
Further, the protruding part is a circular ring-shaped protruding part.
Further, the projections are oppositely disposed.
The invention has the beneficial effects that: compared with an integrated butterfly-shaped connecting key, the problem that the honeycomb restraining system is easy to rotate and fall off is solved, and meanwhile, the honeycomb restraining system can be used for pre-installation, so that the laying time of the honeycomb restraining system is shortened. The connection mode that the syntropy set up only needs just can accomplish the operation in adapting unit's one side, and the installation time that has significantly reduced and to installation space's requirement, lets the connection operation more convenient, and the stability of connecting is higher.
Drawings
Fig. 1 is a split schematic view of the limiting split type connecting key of the invention.
Fig. 2 is a schematic view of the connection structure of the limit split type connection key of the present invention.
In the figure, reference numerals 1 denote a clamping portion, 2 denote an insertion portion, 3 denote a semi-cylinder, and 4 denote a protrusion portion.
Detailed Description
The invention will be described in further detail below with reference to the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation is given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1 and fig. 2, the spacing split type connection key that this embodiment relates to, including joint portion 1 and insertion part 2, joint portion 1 comprises two relative halfcylinders 3 that the front end is connected, has the space that holds insertion part 2 between the halfcylinder 3, and the 3 lateral walls of halfcylinder still have perpendicular outside bulge 4, and insertion part 2 is the T-shaped, and insertion part 2 can insert joint portion 1 and chucking, increases the distance between two halfcylinders 3 simultaneously, bulge 4 is the ring shape bulge, and the increase of distance between the halfcylinder 3 leads to the outside expansion of ring shape bulge, and then chucking adapting unit, preferably, bulge 4 sets up relatively, can be square or arc, and two or more than two pairs of relative settings of quantity play the effect of chucking adapting unit.
For integral type butterfly type connector key, the problem that easy rotation drops has been overcome to spacing split type connector key, can be used for installing in advance simultaneously, reduces honeycomb restraint system's laying time. The connection mode that the syntropy set up only needs just can accomplish the operation in adapting unit's one side, and the installation time that has significantly reduced and to installation space's requirement, lets the connection operation more convenient, and the stability of connecting is higher.
The above description is only a preferred embodiment of the present invention, and these embodiments are based on different implementations of the present invention, and the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
