Abstract
The utility model relates to a round-link chain connecting structure which comprises a front connecting piece and a rear connecting piece, a front connecting piece is provided with a front connecting tooth with the tooth thickness extending along the left-and-right direction, and the rear connecting piece is provided with a rear connecting tooth which is meshed with the front connecting tooth in a complementary mode when used. The front connecting tooth is provided with a connecting hole of the front connecting piece, the connecting hole extends axially along a vertical direction, the rear connecting tooth is provided with a connecting hole of the rear connecting piece, and the rear connecting hole extends axially along a vertical direction and corresponds to and is communicated with the connecting hole of the front connecting piece coaxially when the front connecting piece is meshed with the rear connecting piece. The round-link chain connecting structure further comprises a connecting piece which is arranged inside the connecting holes of the front connecting piece and the rear connecting piece in an inserting mode when in use and carries out limit to the left-and-right motion of the front connecting piece and the rear connecting piece. The round-link chain connecting structure is small in occupied space in the left-and-right direction.
Description
Technical field
The utility model relates to for the hoop chain linkage structure that connects hoop chain.
Background technique
In the equipment of field of mining, often can use the hoop chain that transmission is used, and in order to make a hoop chain consist of enclosed construction or two hoop chains to be coupled together, often need to connect two hoop chain joints by specific hoop chain linkage structure.Existing hoop chain linkage structure such as Chinese patent CN201246442Y disclosed " circular ring chain fast connecting ring ", comprise forward and backward link, be provided with the front connection teeth that transverse tooth thickness is extended along left and right directions on the front link, be provided with the rear connection teeth with the complementary interlock of front connection teeth on the rear connectors, forward and backward connection teeth is locked along bolt, nut that left and right directions extends by the locking direction.During use, two hoop chain joints that need to connect are connected on the forward and backward connection teeth, by the complementary interlock of the rear connection teeth on the front connection teeth on the front link and the rear connectors forward and backward link is moved up in front and back spacing, then by bolt, nut forward and backward link is locked, forward and backward link can not be relatively moved on left and right directions, reach the purpose that two hoop chain joints are connected with this.But this bolt, the nut of passing through is to the spacing form in the forward and backward link left and right sides, the bolt head of bolt and nut all must protrude from forward and backward link at left and right directions, the hoop chain of using for transmission, this has just increased hoop chain taking up room on left and right directions, is not suitable for using in the occasion of some left and right sides limited space systems.
Summary of the invention
The purpose of this utility model is to provide a kind of hoop chain linkage structure that takes up room less at left and right directions.
In order to address the above problem, the technical solution of the utility model is:
The hoop chain linkage structure, before comprising, rear connectors, be provided with the front connection teeth that transverse tooth thickness is extended along left and right directions on the described front link, be provided with when using on the described rear connectors and the rear connection teeth of described front connection teeth complementation interlock, be provided with the front link attachment hole that axially extends along the vertical direction on the described front connection teeth, be provided with on the described rear connection teeth axially and extend along the vertical direction and front, during the rear connectors interlock with the coaxial corresponding rear connectors attachment hole that communicates of described front link attachment hole, described hoop chain linkage structure also comprise be threaded onto when using described before, in the rear connectors attachment hole with to before described, the link that the rear connectors move left and right is spacing.
Described link is for connecting pin, and described forward and backward link attachment hole is pin-and-hole.
The length of described connection pin is not more than the height sum of described forward and backward link on above-below direction.
The beneficial effects of the utility model are: by the forward and backward link attachment hole that axially extends along the vertical direction is set at forward and backward link, during use, can be threaded onto in the forward and backward link attachment hole by corresponding link, and realize spacing to the move left and right of forward and backward link, link is threaded onto in the forward and backward link attachment hole, on left and right directions, can not protrude from forward and backward link, reduce the hoop chain linkage structure in space that left and right directions takies.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the structural representation of front link among Fig. 1;
Fig. 4 is the structural representation of rear connectors among Fig. 1.
Embodiment
The embodiment of hoop chain linkage structure is shown in Fig. 1 ~ 4: comprise front link 1 and rear connectors 2, be provided with the front connection teeth 1-1 that transverse tooth thickness is extended along left and right directions on the front link 1, be provided with when using the rear connection teeth 2-1 with front connection teeth 1-1 complementation interlock on the rear connectors 2, the front link that is provided with axial along the vertical direction extension on the front connection teeth 1-1 connects pin-and-hole 1-2, is provided with on the rear connection teeth 2-1 axially to extend along the vertical direction also to be connected in use the coaxial rear connectors connection pin-and-hole 2-2 of pin-and-hole 1-2 with front link.The hoop chain linkage structure comprises that also being threaded onto described forward and backward link when using connects in the pin-and-hole with the connection pin (not shown) spacing to described forward and backward link move left and right.
During use, two hoop chain joints to be connected link to each other with forward and backward link respectively, then engaged to realize that forward and backward link moves up in front and back spacing by forward and backward connection teeth, in forward and backward link connection pin-and-hole, install the connection pin, spacing with the move left and right that realizes forward and backward link.The upper end that connects pin is not higher than the upper end of front link, the lower end that connects pin is not less than the lower end of rear connectors, the connection pin can not increase the size on forward and backward link left and right directions and the above-below direction, the hoop chain linkage structure can be identical with single hoop chain in the space that left and right directions takies like this, so that this hoop chain linkage structure is fit to some on to left and right directions and on the above-below direction in the conditional working environment of usage space very much, for the connection pin is stable in the pin hole, general the best adopts resilient key.
In other embodiment of this hoop chain linkage structure: some to above-below direction in the hard-core working environment, the length that connects pin also can be greater than the height of forward and backward link on above-below direction; Connecting pin can also be replaced by other links such as screw rods.
