Description

Technical Field

[0001] The utility model relates to the technical field of bus accessories, in particular to a stable bus hanging ring. Background Art

[0002] The number of seats on a bus is limited, so handrail rings are provided for passengers to hold on to in order to prevent passengers from falling during driving. Existing handrail rings are usually connected to the crossbar handrail by a non-elastic sling. When in use, due to the large movable space between the handrail ring and the crossbar handrail, the handrail ring can swing freely and has poor stability. When the bus makes a sharp turn or suddenly brakes, under the action of inertia, the passengers and the handrail rings will move forward due to inertia, which can easily cause the center of gravity to be unstable and dangerous, causing the passengers to fall or sprain their wrists, and it is difficult to provide passengers with a stable grip point. Utility Model Content

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] Provided is a stable bus lifting ring, comprising an outer frame and two gusset plate assemblies, two lifting straps are fixed between the two gusset plate assemblies, mounting plates are fixed to the bottom ends of the two lifting straps, the two mounting plates are fixed to the top surface of the outer frame, a pull ring is slidably matched with the inner side of the outer frame, two first slide grooves are provided in the outer frame, and a gear is rotatably connected in the outer frame, a first rack plate is slidably matched in the first slide groove, a tension spring is fixed between the bottom end of the first rack plate and the bottom of the first slide groove, the first rack plate is meshed with the gear, and two card slots are provided at the bottom of the gusset plate assembly;

[0006] A second sliding groove is provided on both inner side walls of the outer frame, and a second rack plate is fixed on both side surfaces of the pull ring. The second rack plate is slidably fitted inside the second sliding groove, and a spring is fixed between the second rack plate and the bottom of the second sliding groove, and the second rack plate is meshedly connected with the gear.

[0007] Furthermore, a groove is provided on the inner side of the outer frame, and the gear is rotatably connected to the inner side of the groove.

[0008] Furthermore, limiting plates are fixed on both sides of the second rack plate, and a group of limiting grooves connected with the second sliding grooves are opened on both sides of the outer frame, and the limiting plates are slidably fitted in the limiting grooves.

[0009] Furthermore, the two gusset plate assemblies are fixedly connected by a group of second bolts and a group of first bolts. The gusset plate assembly includes two connecting blocks. A connecting rod is fixed between the two connecting blocks. A clamp is provided on the top of the connecting block for fixing to the cross bar inside the bus.

[0010] Furthermore, the second bolt is assembled on the top of the clamp, the inner side of the bottom of the connecting block is provided with a mounting groove, the first bolt is assembled on the bottom of the connecting block, and the middle end of the first bolt is located on the inner side of the mounting groove, and the top end of the sling is wrapped around the outside of the first bolt and clamped in the mounting groove.

[0011] Furthermore, the slot is provided on a side of the bottom surface of the connecting block away from the mounting slot, the top of the first rack plate is a pin structure without teeth, the top of the pin slides through the outer frame and slides in the inner sides of the two slots.

[0012] Furthermore, the two connecting blocks are symmetrically arranged relative to the connecting rod, the two mounting plates are symmetrically arranged relative to the outer frame, the first rack plate is made of metal material, and the top end of the pin is a prism-shaped structure.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The stable bus lifting ring of the utility model example increases the firmness of the connection between the lifting ring and the bus crossbar through the arrangement of two clamps, and has higher structural strength. The arrangement of two slings can give lateral pulling forces in two directions to the outer frame, reduce the lateral swing amplitude of the outer frame, and prevent the outer frame from hitting passengers due to large swings caused by sudden braking of the bus. In addition, the two slings decompose the downward pulling force, have stronger tensile strength, and improve the structural strength and stability of the entire lifting ring.

[0015] 2. In the stable bus lifting ring of the utility model example, when the passenger uses the lifting ring, after holding the pull ring, the natural downward force of the arm is used to cause the second rack plate to slide down in the second slide groove, driving the gear to rotate. The rotating gear drives the first rack plate to slide up, and the pin on the top of the first rack plate will slide into the two slots, so that the buckle plate assembly, the outer frame and the pull ring are connected as a rigid whole. At this time, as long as the passenger holds the pull ring firmly, it will not swing due to the inertia of the bus, and a stable gripping point can be given to the passenger, thereby improving the passenger's riding safety. When the passenger no longer holds the pull ring, the first rack plate slides out of the slot under the action of the tension spring and the elastic restoring force of the spring, and the pull ring slides up to the inside of the outer frame, and the buckle plate assembly and the outer frame are restored to a flexible connection again.
