Detailed Description

The present invention will be further described with reference to the following examples.

The first embodiment is as follows:

a concealed bolt with a simple structure as shown in fig. 1 to 4 comprises a bolt seat 1, a handle 2, a spring plate 5, a push-pull plate 6 and a bolt rod 7.

The lower end of the bolt seat 1 is provided with an installation plate 14, the installation plate 14 is provided with a sliding hole 13, the bolt rod 7 is movably inserted in the sliding hole 13, and the bolt rod 7 can slide up and down in the sliding hole 13.

The front of bolt seat 1 is equipped with handle mounting hole 11, and handle 2 passes handle mounting hole 11, and handle 2 articulates on bolt seat 1 through first round pin axle 3. A recessed handle slot 12 is also provided in the front of the latch housing 1 and the exterior of the handle 2 will be located in the handle slot 12 when the latch lever 7 is in the extended or retracted state.

The lower end of the push-pull plate 6 is fixedly welded with the bolt rod 7, and the upper end of the push-pull plate inclines outwards and is hinged with the inner end of the handle 2 through a second pin shaft 8. Specifically, as shown in fig. 4, a connecting lug 61 is provided at the upper end of the push-pull plate 6, a hinge hole 62 is provided on the connecting lug 61, and the second pin 8 is inserted into the hinge hole 62.

The lower end part of the elastic sheet 5 is welded and fixed on the push-pull plate 6, the back surface of the bolt seat 1 is provided with a stop lever 4 corresponding to the upper end part of the elastic sheet, the stop lever 4 is positioned between the push-pull plate 6 and the upper end of the bolt seat 1, the upper end of the elastic sheet 5 is pressed on the inner surface of the stop lever 4 to generate backward force to the stop lever 4, then the elastic sheet 5 generates forward force to the push-pull plate 6, and the force of the elastic sheet 5 acting on the push-pull plate 6 also acts on the handle 2.

When the handle 2 is pulled, the push-pull plate 6 drives the latch rod 7 to move, in the process, the elastic sheet 5 always generates forward force on the push-pull plate 6 and also always generates restoring force on the handle 2, and in the process, the elastic sheet 5 also slides relative to the stop rod 4.

Seen from above-mentioned structure, will no longer use the mounting such as screw, screw in the dark bolt of this embodiment, the cost is lower, and is simpler, and more reliable.

Of course, the blocking rod 4 can also be arranged at a position corresponding to the middle part of the elastic sheet 5.

Example two:

the difference between the hidden latch of the second embodiment and the hidden latch of the first embodiment is the difference between the spring 5 and the stop lever 4.

As shown in fig. 5, the mounting direction of the elastic sheet 5 of the second embodiment is opposite to the mounting direction of the elastic sheet 5 of the first embodiment, the upper end portion of the elastic sheet 5 of the second embodiment is welded and fixed to the push-pull plate 6, the stop rod 4 is arranged at a position corresponding to the lower end portion of the elastic sheet 5, and the stop rod 4 is directly opposite to the rear portion of the push-pull plate 6.

Example three:

the difference between the hidden pin of the third embodiment and the hidden pin of the first embodiment is the spring piece 5.

As shown in fig. 6, the elastic sheet 5 of the third embodiment is a portion directly cut from the push-pull plate 6, and the lower end of the elastic sheet 5 is still integrally connected to the push-pull plate 6, so that it is no longer necessary to fix the elastic sheet 5, and it is no longer necessary to make the elastic sheet 5 of another material, and at this time, a through hole 63 is formed in a corresponding portion of the push-pull plate 6.

Example four:

the hidden pin of the fourth embodiment is different from the hidden pin of the first embodiment in the spring piece 5 and the stop lever 4.

As shown in fig. 7, the elastic piece 5 of the fourth embodiment is a part directly cut from the push-pull plate 6, as in the third embodiment, but the elastic piece 5 of the fourth embodiment is downward, the upper end of the elastic piece 5 is integrally connected with the push-pull plate 6, the stop lever 4 is arranged at a position corresponding to the lower end of the elastic piece 5, and the stop lever 4 is located right behind the push-pull plate 6.

The above embodiments of the present invention are not right the utility model discloses the limited protection scope, the utility model discloses an embodiment is not limited to this, all kinds of basis according to the above-mentioned of the utility model discloses an under the above-mentioned basic technical thought prerequisite of the utility model, right according to ordinary technical knowledge and the conventional means in this field the modification, replacement or the change of other multiple forms that above-mentioned structure made all should fall within the protection scope of the utility model.
