Detailed Description

The invention will be further described with reference to the following specific embodiments and the accompanying drawings.

As shown in fig. 1 to 6, an optional adaptor for a security door/window includes a rod member body 1, and the rod member body 1 may be a rectangular hollow tube, a circular hollow tube, or an i-shaped rod member. One end of the rod piece body 1 is provided with an expansion joint 2, the other end of the rod piece body is provided with a pulley joint 3, the expansion joint 2 is matched with the upper sliding of the window frame, the pulley joint 3 is matched with the lower sliding of the window frame, namely the expansion joint 2 and the pulley joint 3 are matched with the width of the window-shaped track and can be replaced and changed at will. The rod body 1 is connected through the existing curved arm pieces in sequence, and the anti-theft lattice of the door and the window is formed. The expansion joint 2 comprises an outer joint 201 and an inner joint 202, the inner joint 202 is fixed in the rod body 1, and the outer joint 201 is positioned above the inner joint 202 and matched with the rod body 1 to slide. An expansion piece 4 and a connecting piece 5 are arranged between the outer joint 201 and the inner joint 202. The top of outer joint 201 is provided with spout 6, and spout 6 is used for the last slip of cooperation window frame. The pulley joint 3 comprises a joint seat 301 and a pulley 302 installed in the joint seat 301, the joint seat 301 and the rod body 1 are detachably connected, such as plugging, clamping and the like, and the pulley 302 is used for sliding in cooperation with the window frame.

Wherein, the bottom of the sliding groove 6 is provided with a counter bore 7 vertically penetrating through the whole outer joint 201 downwards, a connecting piece 5 is arranged in the counter bore 7, and the counter bore part of the counter bore 7 has a certain depth and is used for the passage of the connecting piece 5 at the outer joint 201. The connecting element 5 is a countersunk screw which extends through the nipple 202. The countersunk head screw and the countersunk head hole 201 are in clearance fit, so that the extension and retraction of the outer joint 201 are facilitated, and the extension and retraction cannot be restricted or hindered by the countersunk head screw. The countersunk head screw is in threaded fit with the nipple 202, and plays a role in connecting, fixing and adjusting the length.

The top of the inner joint 202 is provided with a column cap 8, the bottom of the outer joint 201 is provided with a blind hole 9, the blind hole 9 corresponds to the column cap 8, and a telescopic piece 4 is arranged between the blind hole 9 and the column cap 8. The telescopic part 4 is a spring, the upper end of the spring is positioned in the blind hole 9, and the lower end of the spring is sleeved on the column head 8. Like this, the spring props up outer joint 201 through elasticity, and outer joint 201 is spacing by countersunk screw again to realize the flexible and adjustable function of outer joint 201.

The connector base 301 is preferably connected to the rod body 1 in a plug-in manner, but it is possible to select different detachable connection manners according to different rod bodies 1. The width of the joint seat 301 is consistent with that of the rod body 1, so that no gap exists when the anti-theft lattice is folded. The length of joint seat 301 matches with the width in the slide rail groove of gliding down, can formulate different pulley joint 3 according to the slide rail groove width of difference like this match can, need not to change whole theftproof check, its adaptability and functional stronger, be favorable to changing, installing, it is with low costs.

The utility model discloses simple structure, reasonable in design, the practicality is strong, is favorable to changing and installing, can cooperate advantages such as to the window frame spout of difference simultaneously, has solved the problem of current existence. The operation method is that the length of the rod body 1 can be adjusted within a certain range according to different door and window heights. The countersunk head screw is rotated upwards to extend the rod body 1, and the countersunk head screw is rotated downwards to shorten the rod body 1. According to the matched pulley joint 3, the rod piece is inserted and connected on the rod piece body 1. During the installation, earlier with expansion joint 2 cooperation in going up the slide, then upwards make power, the spring is compressed, outer joint 201 is flexible in to member body 1, member body 1 shortens, again with pulley joint 3 butt joint in the gliding, loosens member body 1 at last, under the effect of spring force, outer joint 201 stretches out the return, is spacing by countersunk screw to the installation finishes.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
