Abstract

The utility model relates to a device for fixing inner corners of table legs. The device for fixing inner corners of table legs is pillar which is sheathed between two orthogonal plates that compose a table leg and is made of composite materials in an integral forming way. Besides, two slant faces on both sides of the pillar are screwed and fixed on the plates by wood screws and are smoothly appressed on the two plates to keep the plates tightly appressed on the pillar.

Description

The interior angle fixture of table leg

The utility model relates to a kind of interior angle fixture of table leg, and the interior angle that particularly relates to a kind of table leg is fixedly used pilum.

General on four corners of desktop the affixed table leg that forms the right angle with the butt joint of two plates, because of two plates dock built on the sand, so wooden pilum of interior angle socket in the formation of two plates, two oblique surfaces that are posted by two plates of saw are cut in the pilum both sides, and, make two plates be fixed in the oblique surface of pilum with wood screw be spirally connected pilum and two plates.

When cutting the angle of saw two oblique surfaces, cutting angle usually produces error and inaccurate, makes two oblique surfaces often can not be 90 ° of angles, and when being fixed on two plates, two plates also produce deflection makes vertical angle inaccurate.And pilum is the wooden wooden lines that has, and when being spirally connected pilum with wood screw, the hole peripheral that is easy to be spirally connected from wood screw produces the crack, and then damages of splitting, and cuts two oblique surfaces of wooden pilum with manually-operated, more than the procedure and cost high.

The purpose of this utility model, being that a kind of interior angle fixture of table leg is being provided, is exactly at the affixed pilum of two plates of table leg, utilizes the oblique surface of pilum both sides steadily to abut in the two plate interior angles, make two plates be right angle accurately, the good joint plate of firmly shoring of the intensity of pilum.

Feature of the present utility model, be with two at right angles between two plates on the table leg formed of the plate of butt joint one of socket by the integrated pilum of composite, and it is fixing to be spirally connected with wood screw, utilize the pilum both sides to form the oblique surface that is accurate right angle, and the characteristic of the good be full of cracks of composite material strength, two oblique surfaces of pilum are abutted on the interior angle of two plates reposefully, and two plates are right angle accurately, make pilum can shore plate securely.

The interior angle fixture of a kind of table leg of the present utility model, be to set firmly four table legs of being formed with the plate of two Corner butt joints in four corners of a desktop, integrated pilum of composite of each socket between two pole pieces of each table leg, and it is fixing to be spirally connected with wood screw, the pilum both sides are formed with oblique surface, two oblique surfaces are right angle accurately relatively, respectively be provided with on the oblique surface and adhere to line and most grooves, the pilum outer surface is provided with most depressions, in depression, form for what wood screw covered and compress perforation on the face with affixed plate, with pilum both sides oblique surface firm engagement in two plates, make two plates be Corner butt joint accurately, and pilum intensity is good can shore the joint plate securely.

Below by most preferred embodiment and accompanying drawing interior angle fixture to table leg of the present utility model; Be elaborated, in the accompanying drawing:

Fig. 1 is the part combination schematic diagram of the utility model preferred embodiment.

Fig. 2 is the part decomposing schematic representation of the utility model preferred embodiment.

Fig. 3 is the schematic perspective view of the utility model preferred embodiment.

Fig. 4 is the cross-sectional schematic of the utility model preferred embodiment.

Fig. 5 is the cross-sectional schematic of the corresponding plate of groove of the utility model preferred embodiment pilum guiding incline.

As shown in Figure 1, 2, be the preferred embodiment of the interior angle fixture of the utility model table leg, it comprises that four are separately fixed at four pilums 30 on the table leg 20.

Table leg 20 is that correspondence is fixed on four corner location of a rectangle desktop 21, and each table leg 20 has the strip plate 22 that two side butt joints form the right angle, and an end of plate 22 is fixed on four corners of desktop 21.

Pilum 30, be one-body molded with composite (as polypropylene (poly propylene) composite, plastic material), form in pilum 30 both sides two have specific gradient and rectangular relatively oblique surface 31, as Fig. 4, what respectively be provided with concaveconvex shape on the oblique surface 31 adheres to line 32 and most grooves 33.Outer surface 34 both end sides of pilum 30 respectively are provided with two depressions 35, and depression 35 close and parallel oblique surfaces 31 form the smooth face that compresses 36, compress face 36 and are provided with a perforation 36.Outer surface 34 both sides of pilum 30 are provided with the fin 37 that two arches are extended near two oblique surfaces 31.

Perforation 36 covers corresponding to pilum 30 are installed with wood screw 40, and wood screw 40 also is fixed on the plate 22.

The utility model is when being used in combination, be that each pilum 30 is nested with in the interior angle that two plates 22 at each table leg 20 are surrounded, two oblique surfaces 31 of pilum 30 are fitted on the surface of two plates 22, because two oblique surfaces 31 are that to be 90 ° of angles relatively vertical, and two plates 22 of table leg 20 are also vertical relatively, oblique surface 31 specific gradients with pilum 30 two ends can form the convergent shape relatively, and the oblique surface 31 at pilum 30 two ends is enclosed within 22 of two plates, and applying supports on plate 22.

Shown in Fig. 3,4, it is to have the surface of nonslip properties with the plate 22 that firmly reclines because of adhering to line 32 that oblique surface 31 is provided with the purpose that concaveconvex shape adheres to line 32, can apply rubberizing the line 32 of adhering to of oblique surface 31 is fixed with plate 22 fastening applyings, make the oblique surface 31 firm engagement plates 22 of pilum 30 both sides.

Shown in Fig. 3,5, when the purpose that is provided with groove 33 on the oblique surface 31 is when oblique surface 31 applying plates 22, can utilize groove 33 corresponding applyings for the part of plate 22 injustice, so oblique surface 31 still can fit tightly plate 22.Wood screw 40 wears in the perforation 36 of pilum 30, and compress the face that compresses 36 of pilum 30, make the oblique surface 31 of pilum 30 both sides form very big pressure and abut on the plate 22, so can make the oblique surface 31 of pilum 20 and plate 22 keep fitting tightly by above-mentioned groove 33 and wood screw 40.

It is higher and extend into arch fin 37 to be provided with two central authorities on the outer surface both sides of pilum 30, and its purpose is to make pilum 30 to form preferable intensity, can very firmly shore to engage fixed plate 22, makes plate 22 by the support position and be vertical butt joint relatively and fix.

Pilum 30 of the present utility model is that composite is one-body molded, its intensity and force resistance, the more wooden plate of toughness are good, do not have the phenomenon of be full of cracks, and the integral injection molding manufacturing are quick, it is very accurate that its precision can be controlled, and it is vertically very accurate to make the oblique surface 31 of pilum 30 be 90 ° of angles relatively.And solid during at plate 22 when wood screw 40 spiral shells, the face that compresses 36 that can be pressed on pilum 30 forms the location, and wood screw 40 can unrestrictedly not continue to screw in, and plate 22 can not cause the disappearance of sealed wooden plate 22 be full of cracks so wood screw 40 is spirally connected.

In sum, the interior angle fixture of the utility model table leg is one-body molded with composite, has the good advantage that does not chap of accurate intensity, and is placed in the two plate interior angles of table leg, props up plate and makes it be vertical butt joint and firmly engage fixing.
