Description

The metal table foot structure

Technical field

The utility model relates to a kind of metal table foot structure, and referring in particular to a kind of pin upper end build-in that is used in has pad, and is the metal table foot structure of the up-narrow and down-wide Dou taper that inclines in this pad outer rim.

Background technology

Press, desk is present in the human life and occupies the very important ground of a seat, and brings people and enjoy great convenience in life, as: have a meal, write, work ... need use it Deng all; Wherein desk wants can firm support to be placed in the article of its desktop, and the situation that nonvoluntary generation is toppled over, and be to be common people's considering greatly when choosing desk, and the steadiness of desk and durability is established with the structural group of a pin, and sizable close association is then arranged.

Wherein, as shown in Figure 4, be and generally be common in the employed metal table foot group-setting structure of industry, it is made up of desktop 41 collocation table pin 42, wherein:

This desktop 41, it convexes with several trepannings 411 respectively downwards in the periphery appropriate position, this trepanning 411 supports plate 412 in the outer rim utilization, give being welded to each other fixing with desktop 41 bottom faces, then be provided with spacing plate 413 in trepanning 411 upper side, these spacing plate 413 peripheries then are welded to each other fixingly with supporting plate 412, then offer screw 414 in trepanning 411 outsides in addition, this screw 414 can for bolting element 415 revolved establish in.

This pin 42, it just can supply to wear in the trepanning 411 of inserting desktop 41 bottoms of pulling, and can utilize bolting element 415 to give the most urgent contact location.

This structure in group establish in conjunction with the time, see also shown in Figure 5, in its order table pin 42 is pulled by trepanning 411 places of desktop 41 bottoms are slotting, treat after this pin 42 tops are subjected to spacing plate 413 contacts location in the trepanning 411, screw 414 places that offer in trepanning 41 outsides again, utilize bolting element 415 to give establishing, with these pin 42 urgent contact location, make this desktop 41 not produce and rock, do not break away from table pin 42 to inward turning.

Yet, though above-mentioned metal table foot group-setting structure can reach the firm group of expection effect of setting the position, also in using, its actual enforcement finds that this structure still has many disappearances, as:

1, this structure is when assembling is used, because the weight of the related desktop of the weight of its desktop integral body upper end bearing article, all be only to support against the pre-spacing plate of locating that supports of table pin upper end institute, and this spacing plate is the support position at sheet space that only directly is welded in the cover hole peripheral, make the support strength extreme difference that it is whole, very easily when bearing very big weight, cause coming off of this banking stop, and can't bear heavier pressure.

2, this structure is last in desktop and table combining between pin, it is only against being established by trepanning side screw institute spiral shell into the urgent outside of foot location that is resisted against of interior bolting element, make and bear than big pressure or through also rocking or long-term the use down in desktop, cause getting loose of this bolting element, the desktop generation is rocked, unsteady situation takes place and make.

Summary of the invention

The purpose of this utility model provides a kind of metal table foot structure, mainly pad is housed in the table footmuff, between this pad and table pin and with convex ring edge and the mutual build-in of concave ring groove, this pad outer rim then is a up-narrow and down-wide Dou taper that inclines, and with fashionable in utilizing itself and desktop trepanning to overlap, it is good to reach structural strength, and born bigger pressure, and when desktop bears pressure when big more, combine between its desktop and table pin also firm more, to increase desk steadiness and durability.

The utility model provides a kind of metal table foot structure, mainly is made up of desktop, table pin and pad; This desktop wherein, it has supporting seat in the downward respectively solid welding of peripheral position, offers trepanning in the supporting seat inboard, and this trepanning inwall is a up-narrow and down-wide Dou taper that inclines, then in trepanning, offer screw in the supporting seat outside, and for bolting element revolved establish in; This pin, it is arranged with in the upper end position place and is formed with concave ring groove, and combines with its mutual build-in for pad; This pad, it is two-phase corresponding circle arc sheet and rabbets composition mutually, is convexly equipped with in the concave ring groove of the corresponding table of its inner side end pin to be formed with convex ring edge, and end face then is a up-narrow and down-wide Dou taper that inclines in the pad outside; By utilizing pad to be coated on a pin outer rim, and it utilizes the mutual build-in of concave ring groove and convex ring edge to combine each other, and the table pin is inserted urgent combination in the trepanning of the desktop of pulling together with pad again.

The utility model provides a kind of metal table foot structure, and this supporting seat is directly arranged and is welded in the desktop bottom face.

It is good that the utility model can reach structural strength, also increases desk steadiness and durability.

The specific embodiment

At first, see also shown in Figure 1ly, the utility model is made up of desktop 1, table pin 2 and pad 3; Wherein:

This desktop 1, downward respectively solid welding has supporting seat 11 in the periphery appropriate location for it, offer trepanning 12 in supporting seat 11 inboards, these trepanning 12 inwalls are a up-narrow and down-wide Dou taper that inclines, then in trepanning 12, offer screw 111 in supporting seat 11 outsides, with can for bolting element 13 revolved establish in.

This pin 2, it is arranged with in the appropriate position, upper end and is formed with concave ring groove 21, just can combine with its mutual build-in for pad 3.

This pad 3, it is two-phase corresponding circle arc sheet and rabbets composition mutually, is convexly equipped with in the concave ring groove 21 of the corresponding table of its inner side end pin 2 to be formed with convex ring edge 31, then is a up-narrow and down-wide Dou taper that inclines in pad 3 outside end faces.

The utility model is when being used in combination, see also shown in Fig. 2,3, it gives embedding with pad 3 and pulls and be coated on a pin 2 upper ends, pull with the convex ring edge 31 mutual embeddings of pad 3 with the concave ring groove 21 of proper order table pin 2 and to set firmly, table pin 2 being inserted together with pad 3 pulls in the trepanning 12 of desktop 1 and urgent combination location again, and in screw 111 places in desktop 1 bottom supporting seat 11 outsides, with bolting element 13 revolve establish in, make the pad 3 of these these pin 2 outer rim build-ins of bolting element 13 urgent contacts and finish assembling.

In addition, please consult shown in Figure 3ly again, the utility model also can directly be arranged supporting seat 11 be welded in desktop 1 bottom face appropriate position, supports the reinforcement effect can make this desktop have more.

By the above, the composition of this element with use implementation as can be known, the utility model is compared down the following advantage of tool with commonly using:

1, the utility model is in desktop integral body and article overall weight that the upper end bore thereof, be scattered in respectively on supporting seat trepanning inwall and the pad, it is better to make its structural strength commonly use, thus can bear bigger compression weight, and more can increase the durability of the utility model integral body.

2, the utility model is because the pad outer rim cooperates the desktop trepanning all to be a up-narrow and down-wide Dou taper that inclines, make when the compression weight of bearing when desktop is big more, its pin is together with combining between pad and desktop trepanning promptly more for firm, and more can increase the steadiness of the utility model integral body.
