Detailed Description

The invention is further illustrated below by means of specific examples:

as shown in fig. 1, a horizontal push hinge includes a first rail 100, a second rail 200, a first cross link 300, a second cross link 400, and a synchronizing bar 500.

The first guide 100 and the second guide 200 are parallel to each other, and the first cross link 300 and the second cross link 400 are provided in parallel between the first guide 100 and the second guide 200.

The first and

second cross links

300 and 400 have the same structure, and each include a first support bar 310 and a second support bar 320 hinged by a pin at the middle. One end of the first supporting rod 310 and the other end of the second supporting rod 320 located on the same side are fixed hinged ends, and the other end located on the same side are movable hinged ends.

The fixed hinge end of the first cross link 300 is hinged to the first and

second rails

100 and 200 by a first hinge 330. The movable hinge end is hinged with the first slider 104 arranged on the first guide rail 100 and the second guide rail 200 through the second hinge 340.

The fixed hinge end of the second cross link 400 is hinged to the first and

second rails

100 and 200 by the first hinge 330. The movable hinged end is hinged with the second sliding block 201 arranged on the first guide rail 100 and the second guide rail 200 through the second hinge piece 340.

The synchronization rod 500 is disposed outside the first guide rail 100, and two ends of the synchronization rod are respectively stacked and fixed on the first slider 104 and the second slider 201. The synchronizing bar 500 is also provided with a slot 501 therein for avoiding the first hinge 330.

The synchronization rod 500 of the same structure is also fixed in the second guide rail 200 in the same mounting manner, which is not shown in the drawings. Of course, it is also possible to provide the synchronizing bar 500 only at one of the first rail 100 or the second rail 200.

Under the action of the synchronization lever 500, the first and

second cross links

300 and 400 can be operated in synchronization, so that the first and

second guide rails

100 and 200 can be constantly kept parallel when approaching or departing, and the ventilation window, the protection door, and other parts mounted on the horizontal push hinge can be ideally opened in parallel.

Secondly, the synchronous lever 500 is disposed outside the first guide rail 100 or the second guide rail 200 instead of inside the guide rail, so that the sliding resistance can be reduced and the operation of the hinge can be smoother. In addition, the synchronous rod 500 is arranged outside the guide rail, so that the processing requirements on the straightness and the surface smoothness of the synchronous rod 500 can be obviously reduced, the manufacturing is more convenient, and the cost is lower.

Referring to fig. 1 and 2, the first rail 100 and the second rail 200 have the same structure, and have a C-shaped cross section, including a bottom plate 101 and side edges 102 disposed at both sides of the bottom plate 101, and the top of the side edges 102 have parallel inward flanges 103 extending toward each other.

The first slider 104 and the second slider 201 have the same structure, and have a C-shaped cross section, an arch 105 in the middle, and outwardly extending insertion edges 106 on both sides. When the mounting is performed, the insertion edge 106 is inserted into the gap between the base plate 101 and the flange 103, and the sliding on the first rail 100 or the second rail 200 can be realized. The sliding block 104 is preferably made of copper material to reduce resistance and ensure strength.

The arching 105 of the first slider 104 and the second slider 201 is slightly higher than the upper surfaces of the first guide rail 100 and the second guide rail 200. Both ends of the synchronization rod 500 are respectively overlapped on the arch parts 105 of the first slider 104 and the second slider 201, and are fixedly connected with the first slider 104 and the second slider 201 through fixing pins.

In order to make the first and

second cross links

300 and 400 smoothly operate while preventing the first and

second rails

100 and 200 from being scratched, the first and

second hinges

330 and 340 for hinge-coupling preferably adopt the following structure:

referring to fig. 1 and 3, the first hinge member 330 is different in structure according to whether it is located in the slot 501 of the synchronizing lever 500, and for the first hinge member 330 located in the slot 501 of the synchronizing lever 500, it includes a hinge shaft 341 for hingedly fixing the first support rod 310 or the second support rod 320 to the bottom plate 101 of the first guide rail 100 or the second guide rail 200, a washer 342 fitted over the hinge shaft 341, and a guide sleeve 331 fitted over the washer 342. The guide 331 is stepped and includes a first step 332 adapted to the gap of the rail flange 103 and a second step 333 adapted to the width of the slot 401. The guide sleeve 331 is preferably made of a metal material such as stainless steel, copper, or zinc alloy. Thus, when the synchronizing bar 500 moves relative to the first hinge 330, the guide sleeve 331 can perform a guiding and sliding function to reduce the operation resistance.

The top surface height of this packing ring 342 is a little higher than the top surface height of synchronizing bar 500, the top surface height of this uide bushing 331 flushes with the top surface height of synchronizing bar 500, the cover has gasket 334 on the packing ring 342 between uide bushing 331 top surface and first bracing piece 310 or the second bracing piece 320 bottom surface, because the existence of gasket 334, make first bracing piece 310 or second bracing piece 320 and synchronizing bar 500 have certain clearance all the time, avoid scraping each other, reduce the hinge appear the card die or the unusual probability that increases of resistance.

Referring to fig. 1 and 2, for the first hinge member 330 located outside the slot 501 of the synchronizing bar 500, the first hinge member 330 includes a supporting block 335 provided in the first rail 100 or the second rail 200, a hinge shaft 341 for hinge-fixing the first supporting bar 310 or the second supporting bar 320 to the supporting block 335, and a washer 342 sleeved on the hinge shaft 341 for lifting the first supporting bar 310 or the second supporting bar 320. The supporting block 335 is fixedly connected to the first rail 100 or the second rail 200, has substantially the same shape as the slider 104, and also has an arch 105 higher than the first rail 100 or the second rail 200, and the hinge shaft 341 is connected to the arch 105.
