Abstract
The utility model discloses a novel bolt. The bolt comprises a base and a push rod, wherein the push rod is matched with the base; a deflector rod is arranged on the push rod; a hollow metal plate is used as the base; limiting baffle plates relatively extend out of the hollow inner wall along the radial direction of the push rod; the limiting baffle plate is punched to form one or more fixed rings integrated with the base, and an opening which is large enough for the deflector rod to pass through is arranged in the fixed ring; in the embodiment of the utility model, the number of the fixed rings is two and two flanges extend out of the ends of the two fixed rings along the radial direction of the push rod in opposite directions; and a seam joint of the back surface of the base is fixed by welding. The bolt has the beneficial technical effects that the fixed rings and the base are formed by integrally punching, and the seam joint of the back surface is welded in the front and back, so that the whole base is firm and durable; and welding marks between the fixed rings and the base do not exist, so that the appearance is attractive.
Description
Technical field
The utility model relates to a kind of new type bolt, belongs to the technical field for the affixed device of door or window.
Background technology
The bottom surface of tradition latch firm banking forms with a block plate, and clamping rings is welded on above the steel plate of bottom surface, causes retainer ring and bottom surface steel plate sealing-off and has shortened latch application life easily like this.
The utility model content
The purpose of this utility model is to provide a kind of new type bolt that can increase the service life, and solves the shortcoming that prior art exists.
The utility model adopts following technical scheme to realize:
A kind of new type bolt, comprise base and the push rod that mates with base, driving lever is installed on the push rod, it is characterized in that, described base is the metal sheet of a hollow, and the inwall of hollow radially extends position-limited block relatively along push rod, makes position-limited block form retainer ring with the base one by punching press, described retainer ring is one or more, and having on the retainer ring is enough to hold the opening that driving lever passes through.
Further, the quantity of described retainer ring is two, radially extends in the opposite direction respectively two beads in the end of retainer ring along push rod.
Further, the seam crossing of base back surface is by being welded and fixed.
The useful technique effect that the utility model possesses is: retainer ring and base are that integrated punching forms, respectively burn-on a bit before and after the seam at the back side again, whole like this base is very sturdy and durable, and owing to do not have weld mark between clamping rings and the bottom surface, more attractive in appearance.

The specific embodiment
By following description to embodiment; to more help public understanding the utility model; but can't the specific embodiment that the applicant is given be considered as the restriction to technical solutions of the utility model, any definition to parts or technical characterictic change and/or to overall structure do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
New type bolt of the present utility model comprises base 1 and the push rod 2 that mates with base as shown in Figures 1 to 4, and 2 are equipped with driving lever 5 on the push rod, and base 1 is the metal sheet of a hollow as shown in Figure 3; Material is preferably steel plate, the inwall of hollow radially extends position-limited block 4 relatively along push rod 2, make the retainer ring of position-limited block 4 formation and base one by punching press, retainer ring is one or more, having on the retainer ring is enough to hold the opening that driving lever passes through, the quantity of retainer ring is two in the present embodiment, in the end of retainer ring along push rod radially extend in the opposite direction respectively two beads 6, the seam crossing 3 of base back surface is by being welded and fixed.Whole firm banking 1 is comprised of a steel plate, the steel plate die mould is formed retainer ring and the base that the bottom surface is connected as a single entity, respectively burn-on a bit in the seam at back side front and back, whole like this base is very sturdy and durable, and owing to do not have weld mark between clamping rings and the bottom surface, more attractive in appearance.The effect of two permanent opening annulus is exactly when latch uses in the middle of arranging, and above the opening annulus that can be fixed in the above push rod, when latch uses, can be fixed under the lower aperture annulus, reaches the locking purpose.
Certainly; the utility model can also have other various embodiments; in the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
