Description

TECHNICAL FIELD

[0001] The utility model relates to a door closer field especially to a slide rail quick -mounting clasp spring rocker. BACKGROUND

[0002] The door closer can keep the fireproof door in the normally closed or normally open state, or play the role of blocking the spread of fire or facilitating people to walk through, and the application of the door closer is very wide, the door closer is a similar spring hydraulic device, when you manually push the door open, the spring in the door closer is compressed to store energy, and then the spring is released to transmit the door closing force to the door leaf through the rocker of the door closer, so that the door is closed actively without external force, and the door frame and the door body are protected from violent impact, the existing door closer rocker has obvious deficiencies in the installation process, that is, the installation efficiency is slow, that is, the two rocker arms in the rocker need to be hinged together through fasteners, which greatly reduces the installation efficiency of the door closer. SUMMARY

[0003] The utility model solves the above-mentioned prior art defects, and provides a slide rail quick-mounting clasp spring rocker capable of quickly assembling the rocker, meeting the requirements of quick installation and high efficiency of the rocker.

[0004] The utility model discloses a technical scheme that solves the technical problems: the slide rail quick-mounting clasp spring rocker, first rocker arm and second rocker arm are fixed with the bolt at the outer end of the first rocker arm, the mounting seat is fixed with the mounting seat at the outer end of the second rocker arm, the mounting seat is opened with the insertion hole matched with the bolt, the insertion hole is opened with the clasp spring groove, the clasp spring groove is installed with the clasp spring, the bolt includes the cylinder and the insertion block at the top of the cylinder, and the cross section of the insertion block is greater than that of the cylinder. Here, the functions of the bolt, the mounting seat, the insertion hole, the clasp spring groove and the clasp spring are that the first rocker arm and the second rocker arm can be quickly assembled and hinged together, and the rocker can be assembled, so that the installation efficiency of the door closer can be greatly improved.

[0005] Further improvement, the outer contour of the insertion block is conical. Here, the function of the conical shape is to facilitate and quickly guide the assembly of the insertion block to the insertion hole.

[0006] Further improvement, the outer contour of the insertion block is arc-shaped at the top and the bottom. Here, the function of the arc is to facilitate the expansion of the clasp spring, thereby facilitating the quick assembly or disassembly of the first rocker arm and the second rocker arm.

[0007] Further improvement, the outer contour of the insertion block is provided with a self-lubricating layer. Here, the self-lubricating layer can reduce the friction resistance between the insertion block and the mounting seat, and the noise of the rocker is smaller; here, the self-lubricating layer is made of tin bronze material.

[0008] The utility model discloses the beneficial effect is:

[0009] 1). Through the latch, mounting seat, jack, card spring groove, card spring can quickly first rocker and second rocker card joint assembly hinged together, assembled into a rocker, can greatly improve the installation efficiency of the door closer;

[0010] 2). Not only convenient rocker card installation, also convenient, quick rocker disassembly;

[0011] 3). Rocker running resistance, noise is small. BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 2 It is Figure 1 A-A section view.

[0014] Mark for explanation: first rocker 1, second rocker 2, latch 3, cylinder 3-1, plug 3-2, taper 3-2a, circular arc 3-2b, self-lubricating layer 3-3, mounting seat 4, jack 4-1, card spring groove 4-1a, card spring 5, door closer 6. DETAILED DESCRIPTION

[0015] The utility model will be further described in connection with the drawings:

[0016] Referring to the drawings: this slide rail quick-mounting card spring rocker, including first rocker 1 and second rocker 2, the outer end of first rocker 1 is fixed with latch 3, the outer end of second rocker 2 is fixed with mounting seat 4, and the mounting seat 4 is provided with jack 4-1 matched with latch 3, the jack 4-1 is provided with card spring groove 4-1a, the card spring groove 4-1a is installed with card spring 5, the latch 3 includes cylinder 3-1 and plug 3-2 located at the top end of cylinder 3-1, and the cross section of plug 3-2 is greater than the cross section of cylinder 3-1.

[0017] The outer contour of plug 3-2 is taper 3-2a that is small on top and large at bottom.

[0018] The outer contour top end and bottom end of plug 3-2 are circular arc 3-2b.

[0019] The outer contour of latch 3 is provided with self-lubricating layer 3-3.

[0020] The utility model discloses a working principle: first, the door closer 6 is installed on the door frame, then the second rocker 2 upper articulated member is installed on the door, then, the first rocker 1 is assembled on the pivot of the door closer 6, then adjust the position of the door, make the first rocker 1 and the second rocker 2 be in reasonable angular position, then, the bolt 3 on the first rocker 1 is quickly matched to the insertion hole 4-1 through the insertion block 3-2, at this time, the snap spring 5 has been located at the snap spring groove 4-1a, and the insertion block 3-2 of quick insertion can open the snap spring 5 and make the snap spring 5 reset to the original state at the cylinder 3-1, so that the installation of the rocker arm and the installation of the door closer are completed, and the efficiency is very high, because the connecting part of the rocker arm during the work of the door closer, the force generated is in the transverse direction, so in the longitudinal direction, as long as the position can be clamped, the first rocker 1 and the second rocker 2 can not be separated in the longitudinal direction, so the blocking force generated by the snap spring is enough, and the frictional resistance between the insertion block 3 and the mounting seat 4 is small due to the effect of the self-lubricating layer 3-2a, the noise of the rocker arm running is extremely small, and it is worth popularization and application.

[0021] Although the utility model has been illustrated and described through the reference preferred embodiment, but, the professional ordinary skilled person should understand, in the scope of the patent claim, can make various various changes on the form and the details.
