Description

The structure-improved of shelving combination

The utility model relates to a kind of structure-improved of shelving combination, refers to that especially a kind of can fixing fast simultaneously makes it have the structure-improved of the more firm a kind of shelving combination that is difficult for rocking by combining closely of suit place.

As shown in Figure 1, traditional shelving combination is by several sleeve A, joint seat B and plate body (not shown) are formed, wherein sleeve A is a hollow tube, then be provided with several connecting heads C on each joint seat B, as shown in Figure 1, the footpath just can be inserted in the sleeve A and be mutually combined to reach outside the connecting head C, need only the length of change sleeve A and be used joint seat B by aforesaid structure user with varying number connecting head C, can assemble out different sizes fast, the shelving combination of the volume and the number of plies, because it has aforesaid convenience and polytrope, so it quite is subjected to liking of ordinary consumer and businessman, though the aforementioned shelving combination of inner and outer pipes fit that mainly utilizes has assembling quick advantage easily, but it still has many shortcomings and demands research urgently and improve on reality is used, at first, connecting head C on the joint seat B can insert the purpose that reaches quick assembling in the sleeve A easily for convenience, the external diameter of connecting head C all can be less than the internal diameter of sleeve A, therefore when reaching ease of assembly, more or less all can there be certain clearance after connecting head C and the sleeve A assembling and can't closely chimericly fixes, cause firm inadequately being easy to generate of structure of assembling back shelving combination to rock, especially come to cause easily especially to topple in earthquake temporarily, therefore it also can't bear too big strength, so shelving combination commonly used also is not suitable for putting overweight, frangible or emphasis is unstable topple over easily article, cause the purposes of actual use to be subjected to great restriction, also want extreme care if will move or directly carry shelving combination on the other hand, because accidentally connecting head C promptly can break away from sleeve A and produce accident, cause the very big inconvenience of user to demand being studied improvement urgently with puzzlement.

Though shelving combination commonly used has characteristics easy to assembly, but it still has the firm inadequately shortcoming of rocking that is easy to generate of structure, in order to improve above-mentioned every shortcoming, the utility model designer studies intensively with great concentration to be engaged in year research and development more than such Related product, manufacturing and marketing experience; Through constantly making great efforts research, test and improvement, propose a kind of reasonable in designly finally, and can effectively improve the utility model of above-mentioned shortcoming.

The main purpose of the utility model is the structure-improved that is to provide a kind of composition, to overcome the shortcoming of prior art shelving combination.

A kind of structure-improved of shelving combination, it mainly is by joint seat, sleeve pipe, plate body and screw are formed, wherein joint seat is provided with more than one connecting head, sleeve pipe is a hollow tube, by being formed a Combined shelf body, joint seat and sleeve combination make plate body can place on the Combined shelf body, it is characterized in that: the front end of connecting head is provided with two elastomers, be provided with screw in an elastomer wherein, the relative position place that is engaged in simultaneously on the sleeve pipe is provided with penetration hole, after the connecting head on the joint seat is in inserting sleeve pipe, the penetration hole that passes on the sleeve pipe with screw is screwed in by the screw of connecting head front end elastomer, make the front end of screw withstand the elastomeric inwall of opposite side, this elastomer is reached to extrapolation strut, packing, in conjunction with locking.

Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing, so that further understand the purpose of this utility model, effect and feature.Wherein:

Fig. 1 is the three-dimensional exploded view of joint seat and sleeve pipe in the common combinations frame;

Fig. 2 is the three-dimensional exploded view of the utility model sleeve pipe and joint seat;

Fig. 3 is the three-dimensional combination figure of the utility model;

Fig. 4 is the generalized section of the utility model connecting head and thimble joint;

Fig. 5 A, Fig. 5 B are another enforcement illustrations of the utility model joint seat.

At first, see also Fig. 2 and Fig. 3, be three-dimensional exploded view and three-dimensional combination figure for the utility model, the structure-improved of the utility model shelving combination mainly is by joint seat 1, sleeve pipe 2, plate body 3 and screw 4 are formed, wherein joint seat 1 is provided with more than one connecting head 11, sleeve pipe 2 is to be a hollow tube, by being combined to form a Combined shelf body, joint seat 1 and sleeve pipe 2 make plate body 3 can place on the Combined shelf body, it is characterized in that, end is provided with two elastomers 12 before the connecting head 11, be provided with screw 13 in an elastomer 12 wherein, the relative position place that is engaged in simultaneously on the sleeve pipe 2 is provided with penetration hole 21, after connecting head 11 on joint seat 1 inserts in the sleeve pipe 2, the penetration hole 21 that passes on the sleeve pipe 2 with screw 4 is screwed in by the screw 13 of connecting head 11 front end elastomers 12, makes before the screw 4 end withstand within the opposite side elastomer wall and this elastomer 12 is reached to extrapolation (as shown in Figure 4) combines closely, the effect of locking.

In the described structure of leading portion, set penetration hole 21 is to lock to make things convenient for screw 4 for slotted hole on the sleeve pipe 2, and side can be located within the sleeve pipe 1 in the position of penetration hole 21 in addition or the bottom surface makes it have more effect attractive in appearance.

Again, screw 4 in the utility model can use grub screw, as Fig. 2 and shown in Figure 4, or screw 13 front ends that sunk screw 5 is engaged in connecting head 11 front end elastomers 12 simultaneously are provided with shrinkage pool 14, shown in Fig. 5 A, make this screw 4 or sunk screw 5 after locking screw 13, it is outer and can be hidden in fully in the sleeve pipe 2 that end can not protrude in sleeve pipe 2 outside the screw 4,5, makes it have effect more attractive in appearance.

The section configuration of sleeve pipe of the present utility model 2 and connecting head 11 also can be used circle or other polygonals except the square shown in graphic, can both reach identical effect, in addition, joint seat 1 of the present utility model can be looked actual demand and make the structure (shown in Fig. 5 A and Fig. 5 B) with varying number connecting head 11, so as to the variation that increases shelving combination and increase its practicability.

The above is the preferred embodiment of the utility model, the scope that the utility model is contained is not limited to the embodiment shown in the utility model, all changes of being done according to the utility model content, the embodiment of effect that it produced and feature and the utility model is similar, and can all belong to the scope that the utility model is contained by knowing the conceiver of this those skilled in the art institute.

In sum, the structure-improved of a kind of shelving combination of the utility model, it not only has simple in structure, the low easy feature of manufacturing assembling that reaches of cost, it not only possesses has the assembling of common combinations frame to be easy to advantage, the elastomer that can utilize screw will fill in the interior connecting head front end of sleeve pipe simultaneously really struts and withstands wall within the sleeve pipe, make to combine more closely firmly between this joint seat and sleeve pipe, make the characteristics of the soundness of its convenience that has shelving combination simultaneously and fixing frame.
