[0003] The existing horizontal bar on the door is usually a non-drilling horizontal bar, which includes an extendable holding cross bar and horizontal support seats at both ends of the holding cross bar. When installing, by making the holding cross bar extend relatively, the horizontal support seats at both ends support on the wall. However, the support of this kind of horizontal bar on the door only relies on the friction between its two horizontal support seats and the wall for support and fixation, and the stability is insufficient. When in use, the horizontal bar is easy to fall off, and then it is easy to cause the situation of the user falling and being injured, and there are relatively large safety hazards.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0027] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] Refer to Figure 1-7As shown in the figure, as an embodiment of the present utility model, a gantry-type horizontal bar device is provided, which includes a gantry and a horizontal bar. The gantry includes two vertically arranged side columns 2 arranged opposite to each other and a cross beam 1 connected between the tops of the two vertically arranged side columns 2. The vertically arranged side columns 2 are provided with a plurality of positioning holes 3 along the up and down direction. The horizontal bar includes a gripping cross bar 4 and pin columns 5 that can be elastically telescoped at both ends of the gripping cross bar 4. Through the movable limit fit between the pin columns 5 and the positioning holes 3, the height of the horizontal bar can be adjusted and fixed between the two vertically arranged side columns 2. When the height of the horizontal bar needs to be adjusted, first control the pin columns 5 to retract inward, so that the pin columns 5 withdraw from the positioning holes 3. After the whole horizontal bar is moved to the required height position, then control the pin columns 5 to extend outward so that they are fixedly limited in the positioning holes 3 through perforation, thereby completing the height adjustment process of the horizontal bar, and this adjustment process only takes 3 seconds, and the adjustment operation is convenient and fast. Through the corresponding limit fit between the pin columns 5 and the positioning holes 3, the present utility model realizes the fixed support of the horizontal bar between the two vertically arranged side columns 2, with better stability and a larger load-bearing range. After testing, the maximum load-bearing value is 1000 kgs, which can prevent the horizontal bar from falling off during use, thereby avoiding the situation of users being injured and eliminating potential safety hazards.

[0029] Specifically, the gantry has 40 pairs of positioning holes 3, that is, 40 adjustment gears. The height range corresponding to the positioning holes on the vertically arranged side columns is 15 - 208 cm, that is, the highest gear height is 208 cm, the lowest gear is 15 cm, and the spacing range between two adjacent positioning holes up and down is 2 - 7 cm. In this embodiment, the spacing between two adjacent positioning holes up and down is 5.08 cm. This setting can meet the adaptation adjustment and use of different users and users at different times due to different heights, and meet the use requirements in most cases.

[0030] In this embodiment, the horizontal bar further includes a pulling member 6 and an elastic member 7. A through activity channel 8 is formed inside the gripping cross bar 4. Long slot holes 9 communicating with the activity channel 8 are opened at both ends of the gripping cross bar 4. A blocking member 16 is arranged in the activity channel 8. The elastic member 7 is installed in the activity channel 8 between the blocking member 16 and the pin column 5. A connecting rod 10 is arranged on the pin column 5. The connecting rod 10 passes through the long slot hole 9 and is fixedly connected to the pulling member 6. The pulling member 6 is used to drive the pin column 5 to move telescopically in the activity channel 8. Specifically, the elastic member 7 is closer to the middle of the gripping cross bar 4 than the pulling member 6. The elastic member 7 is a spring. When the user holds the pulling member 6 and moves it inward, the pin column 5 is driven to move inward and retract, so that the pin column 5 withdraws from the positioning hole 3. At this time, the spring is compressed and stores energy. When the user releases the pulling member 6, under the elastic force of the spring, the pin column 5 moves outward and extends to reset, so that the pin column 5 is fixedly limited in the positioning hole 3 through perforation.

[0031] In this embodiment, the gripping bar 4 is made of 304 stainless steel, which has better feel and strength. The pulling member 6 is an annular pulling member 6 mounted on the outside of the gripping bar 4, which is convenient for both hands to hold tightly for pulling operations, and has better comfort and stability.

[0032] In this embodiment, there are two long slot holes 9 at one end of the holding bar 4 which are arranged opposite to each other up and down, and the length direction of the long slot holes 9 is the same as the length direction of the holding bar 4, so that the guiding stability of the pin 5 is better during telescopic movement.

[0033] In this embodiment, the door frame is an aluminum alloy door frame, and a track 15 is arranged on the inner side of the vertical side column 2. The horizontal bar also includes sliders 12 fixedly installed at both ends of the holding horizontal bar 4. The sliders 12 are set in the track 15 for sliding up and down. This arrangement ensures that the horizontal bar will not be separated from the door frame when adjusting the height and during the movement, thereby further improving the safety and reliability of the use process.

[0034] In this embodiment, the slider 12 is a long rectangular metal slider, which is provided with a clearance hole 13 . The slider 12 is sleeved on the outside of the two ends of the holding bar 4 through the clearance hole 13 .

[0035] In this embodiment, anti-rotation plates 14 are fixedly connected to the bottom sides of both ends of the holding bar 4, a limiting hole 11 is provided on the slider 12, one side of the anti-rotation plate 14 is locked and fixed in the limiting hole 11, thereby preventing the slider 12 from rotating relative to the holding bar 4, and the anti-rotation plate 14 is arranged on the bottom side of the holding bar 4, which is more beautiful and stable and reliable.

[0036] Specifically, it also includes a screw lock part. The slider 12 and the anti-rotation plug plate 14 are provided with corresponding locking holes. The screw lock part cooperates with the locking holes to lock and fix one side of the anti-rotation plug plate in the limiting plug hole 11.

[0037] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes made to the present invention in form and detail, without departing from the spirit and scope of the present invention as defined in the appended claims, shall fall within the scope of protection of the present invention.
