Abstract

The utility model discloses a combined rack which comprises a base, an insertion type connection pipe, and a reinforcing disc, wherein, the base is formed by the engagement of four arc-shaped stand bars adopting a swallow-tailed mortise structure. The insertion type connection pipe is inserted in and connected with a circular ring groove at the center of the base. The reinforcing disc is clamped on an elastic clip hook at the lower part of the base. The combined rack which is provided by the utility model has the advantages of large bearing capacity, beautiful appearance, low cost, and convenient storage and transportation, and can be disassembled. The utility model is the better combined rack, compared with the prior art.

Description

Modular support

The utility model relates to support, is specifically related to a kind of removable modular support.

Usually, people adopt support to do the carrier of ornament when making some tree-shaped ornaments (as Christmas tree), generally adopt plastic cement to make, and the center of this support can not be unsettled, if unsettled, rack bearing power is then less.And not unsettled inevitable moulding is stiff, stereotyped in the middle of the support, and profile is difficult to be broken through, and sight is poor.

The purpose of this utility model is to provide that a kind of bearing capacity is big, cost is low and the unsettled modular support of removable support bottom center.

The purpose of this utility model adopts following technical scheme to realize: construct a kind of modular support, comprise a base, socket connection pipe and reinforce disk, described base adopts tenon, groove structure grafting interlock to form by 4 arc legs, described socket connection pipe is plugged in the annular groove of being made up of described 4 arc legs, and described reinforcing disk is connected on the elastic fastening hook of 4 legs.

The tenon of described arc leg, groove structure are to be provided with one 90 ° fan-shaped cylinder at an end of leg, on two side planes of cylinder, respectively be provided with the tenon of a swallow-tail form, on two side planes of another leg cylinder, then respectively be provided with a dovetail groove, promptly be provided with in pairs.

Described socket connection pipe is that the end at a hollow pipe is provided with interface, is shaped on 2 guide-localization grooves on the inner surface of interface, and symmetry is shaped on two clamping through holes on the body of interface; The other end at tube connector is provided with a grafting tubing string identical with the interface diameter, is provided with on its surface and corresponding 2 the location tenons of interface, with the corresponding clamping small boss of described clamping through hole; On tubing string, also have 2 opening straight troughs.

Symmetry is shaped on by the termination to two that hold tail uniform zigzag small stairs on the outer surface of described tube connector.

Described arc leg is that the arc rounding off by different curvature forms an arc support plate, is provided with reinforcement below support plate, is shaped on reinforcement and reinforces the disk elastic fastening hook and the open slot of clamping mutually.

On the disk of described reinforcing disk, be evenly equipped with 4 with the wide locating slot of leg reinforcement, be provided with and the corresponding blocked hole of leg elastic fastening hook at bottom land.

Implement modular support of the present utility model, its base is made up of by the tenon groove structure grafting interlock of swallow-tail form 4 arc legs, in conjunction with tight, the bearing capacity of arc leg is more many greatly than the bearing capacity of other structure leg, under the effect of reinforcing disk, and its good integrity, intensity is higher, with tube connector termination another tube connector end of pegging graft, can many tube connectors freely be pegged graft according to different demands and be combined into the mobile jib of differing heights, be fit to different purposes and convenient the use; This support adopts dismantled and assembled structure, and unsettled, handsome in appearance in the middle of the base; The convenient storage and transportation, cost is low; It is the good modular support of a kind of performance.

Below in conjunction with drawings and Examples, further describe the utility model, in the accompanying drawing:

Fig. 8 is the grafting column structure schematic diagram of tube connector shown in Figure 6.

With reference to each accompanying drawing, modular support of the present utility model comprises base, socket connection pipe 3 and reinforces disk 5 that base adopts the form grafting interlock of tenon, groove structure to form (Fig. 1) by 4 arc legs 4; Described tenon groove structure is to be provided with fan-shaped cylinder 8 (Fig. 2-Fig. 4) of one 90 ° at an end of an arc leg 4, on two side planes of cylinder, respectively be provided with a swallow-tail form tenon 13,14 (Fig. 3), then respectively be provided with a dovetail groove 11,12 (Fig. 4) on cylinder two side planes of another arc leg, promptly the column side face of 4 arc supports is provided with 4 pairs of swallow-tail form tenons, the groove of the interlock of can pegging graft mutually; 4 leg grafting interlocks are good, and the end face of 4 fan-shaped cylinders and leg is formed an annular groove 1, and an end of socket connection pipe 3 is plugged in this annular groove.As shown in Figure 2, be to improve the intensity of leg, the support plate of leg 4 is designed to the arc support plate 6 be made up of different curvature plate rounding off, below support plate, be provided with reinforcement 7, below reinforcement, be provided with and reinforce disk 5 elastic fastening hook 2 and the

open slot

9,10 of clamping mutually, as shown in Figure 5.Described reinforcing disk 5 is to be provided with 4 equally distributed straight troughs 15 on its disk, have in the bottom of each straight trough one can with the suitable blocked hole 16 of elastic fastening hook 2.

Shown in Fig. 6-8, described socket connection pipe 3 is that the end at a hollow pipe is provided with an interface 19, on the inner surface of interface 19, be shaped on the guide-localization groove 24 that is no less than 2, on the body of interface 19, be symmetrically arranged with two blocked holes 20, the other end of tube connector 3 be provided with one straight with interface 19 through identical grafting tubing string 17, be provided with and corresponding positioning convex strip 22 and two positioning tooths 21 that are no less than 2 of interface on its surface, pegging graft, on tubing string, have many open slots 23 to making tubing string flexible.

During assembling, 4 leg grafting interlocks are good, load onto the reinforcing disk, tube connector on pegging graft in the annular groove of base, the mobile jib that the last many tube connectors of can pegging graft are as required formed differing heights is used for different ornaments.It is big that this support has bearing capacity, intensity height, good looking appearance, the characteristics that cost is low.
