Lock latch of telescopic pole connection part
Technical field
The utility model belongs to demonstrating apparatus technical field, relates to a kind of lock latch of telescopic pole connection part.
background technique
Top and bottom column is a kind of demonstrating apparatus for places such as large-scale shopping plaza, clock and watch, household electrical appliances, clothes sale monopoly, cosmetics, cosmetology salons.Existing market, shop can often use top and bottom column and support the exhibition booth of opening up bar or supported by exhibition bar to show the commodity such as clothes while arranging Display Rack, the height of exhibition bar or exhibition booth need be able to regulate arbitrarily, to meet different user demands.On a top and bottom column, be often provided with multiple snap close connection parts, if the patent No. is the pipe snap close on " adjustable heaven-earth pole " of " 201020674581.4 ", for another example the patent No. is " 201020674607.5 " " lock latch of telescopic pole ", all there is following shortcoming: first, dismounting difficulty, after general top and bottom column installs, just can need according to showing, lock latch of telescopic pole is installed on top and bottom column, reduce after showpiece, after top and bottom column need to being packed up, the lock latch of telescopic pole being placed on above top and bottom column could be pulled down.Second, can not be applicable to the top and bottom column of different-diameter, " lock latch of telescopic pole " this snap close that is " 201020674607.5 " as the patent No. coordinates with top and bottom column by two trips of inner side, this snap close complex manufacturing technology, and on top and bottom column, also will join and do and the corresponding groove of trip, cost significantly promotes.Because trip is axially to arrange, so the loading weight can bear for lock latch of telescopic pole does not have a significant effect, and trip can not be at radial expansion, thus run into slightly greatly or slightly the top and bottom column of minor diameter cannot use.The 3rd, connecting groove is few, and connecting direction is single, can not carry different types of multiple article.
Summary of the invention
For above-mentioned situation, the utility model provides a kind of lock latch of telescopic pole connection part, uses simply, and easy accessibility, can adapt to the top and bottom column of different-diameter size, and is provided with multi-direction connecting groove, as required the different showing article of connection.
To achieve these goals, the technical solution of the utility model is as follows:
Lock latch of telescopic pole connection part, comprise snap close body, it is characterized in that, snap close body is fabricated structure, snap close body comprises two semiorbicular snap close splicing components, the stitching portion of a snap close splicing component is provided with tenon, and the relevant position of another snap close splicing component is provided with tongue-and-groove, and described tenon is connected with tongue-and-groove clamping.
Described snap close splicing component is provided with tapping hole radially, in tapping hole, be provided with the screw rod mating with tapping hole screw thread, screw rod outside is fixedly connected with rotatable handle, push jack inside screw rod, push jack top is provided with block, push jack middle part one side is provided with two guide pillars, on snap close splicing component, is provided with guide groove with the corresponding position of guide pillar.
Described lock latch of telescopic pole connection part also comprises gasket ring, top and the bottom of gasket ring periphery are equipped with fixture block, the inwall at snap close splicing component two ends is provided with draw-in groove, fixture block and draw-in groove clamping, in gasket ring, be also provided with thickening ring, thickening ring top and bottom are equipped with folding edge, and thickening ring is connected on gasket ring by folding edge.
Described snap close splicing component periphery is provided with some connection snap close splicing component top layers and bottom and the T-shaped groove that do not connect.
The number of described T-shaped groove is 7.
The folding of described thickening ring top and bottom is all greater than gasket ring external diameter along diameter.
The utility model has the advantages that: use simply, easy accessibility, can adapt to the top and bottom column of different-diameter size, and is provided with multi-direction connecting groove, as required the different showing article of connection.
