Abstract
The utility model discloses a welded nut, which is a cylindrical structure, wherein the exterior of the cylindrical structure is annularly provided with a boss. The welded nut is divided into an insert portion and a connection portion through the boss, a screw hole extending to the connection portion is processed into the insert portion, and one end of the boss approaching the connection portion is inwards concave to form an annular step. The boss of an original welded nut contacts with a mounting surface and is provided with the step, thereby leading soldering tin to coat the boss on the bottom layer of the step during welding and avoiding faulty welding. Simultaneously, height of the soldering tin does not exceed the top of the step, thereby effectively controlling using quantity of the soldering tin without wasting, and leading welding spots to be attractive.
Description
Technical field
The utility model relates to nut, more particularly, relates to the improvement to a kind of welded nut.
Background technique
At present, at some occasion is installed and adopts welded nut to increase the tightness and the sealing of connection, need adopt welded nut to connect when installing as LED public transport stop board display screen box body.With reference to Fig. 1, for the used welded nut 91 of display screen box body, with reference to Fig. 2, for described welded nut 91 and display screen box body 92 are installed sectional view.Welded nut shown in the figure 91 has an insertion part 911 and a junction 912, described joint 912 is provided with an annular protrusion 9121, inserted in the mounting hole (not shown) of display screen box body 92 described insertion part 911 when described welded nut 91 was connected with display screen box body 92, and around described annular protrusion 9121 and display screen box body 92 surface of contact, weld, as shown in FIG., because described annular protrusion 9121 is vertical the contact with display screen box body 92, in when welding if adopt less scolding tin, can cause rosin joint at the surface of contact edge, can not accomplish waterproof, dustproof; If adopt more scolding tin, then the amount of wayward scolding tin causes waste, and face of weld is not attractive in appearance.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of welded nut, adopts this welded nut can guarantee effectively that welding quality avoids the waste to scolding tin simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of welded nut is provided, it is the cylindrical structural that an external rings is provided with boss, described boss is divided into insertion part and joint with described welded nut, be processed with the screw that extends to joint in the described insertion part, it is characterized in that: an end of the close described joint of described boss caves inward and forms a ring-shaped step.
Technical solutions of the utility model will be established a step on original welded nut with on the boss that attachment face contacts, the boss of scolding tin parcel step bottom when making welding, avoid occurring rosin joint, the height of scolding tin is no more than the top of step simultaneously, effectively controlled the scolding tin consumption, can not cause waste, and make solder joint attractive in appearance.
Description of drawings
Fig. 1 is a kind of welded nut structural representation in the prior art;
Fig. 2 is the installation sectional view of welded nut shown in Fig. 1;
Fig. 3 is the structural representation of the utility model one preferred embodiment;
Fig. 4 is the installation sectional view of welded nut shown in Fig. 3.
Embodiment
In order to make technical problem to be solved in the utility model, technological scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 3, be the structural representation of the utility model one preferred embodiment.With reference to Fig. 4, be described welded nut 1 and a display screen box body 2 installation sectional views.Welded nut shown in the figure 1, it is the cylindrical structural that an external rings is provided with boss 11, described boss 11 is divided into insertion part 12 and joint 13 with described welded nut 1, be processed with the screw 14 that extends to joint 13 in the described insertion part 12, an end of described boss 11 close described joints 13 caves inward and forms a ring-shaped step 111.
During installation, the insertion part 12 of described welded nut 1 is inserted in the attachment hole of display screen box body 2, this moment, boss 11 formed a surface of contact near the plane and the described display screen box body 2 of insertion part 12, for prevent rainwater, dust from then on surface of contact enter, need to adopt scolding tin carry out seal welding around the described boss 11.Owing to be formed with a ring-shaped step 111 on the described boss 11, during welding, with scolding tin cover the boss of step 111 bottoms and contact with display screen box body 2 around, wrap with the boss of scolding tin step 111 bottoms like this and effectively avoided rosin joint, guaranteed welding quality, simultaneously with the site of exceeding, the top of step 111, the height of scolding tin is no more than this spacing point, effectively control the scolding tin consumption, can not cause waste, and made solder joint attractive in appearance.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
