Detailed Description
The present invention will be described in further detail with reference to the following examples, which are given in the accompanying drawings.
As shown in fig. 1 to 6, the present embodiment provides an example of a horizontal bar support including a fixed member 1 and a movable member 2, the fixed member 1 having a cavity 11 opened to face the movable member 2, the movable member 2 having a connecting portion 21 fitted into the cavity 11, the connecting portion 21 being slidable in the cavity 11 in the up-down direction. The cavity 11 is provided with a stop protrusion 111, and the connecting portion 21 is provided with an elastic limiting member 211 engaged with the stop protrusion 111. When the connecting portion 21 is in the initial installation state, the upper end of the connecting portion 21 abuts against the upper end wall 112 of the cavity 11, and the lower surface 2111 of the elastic limiting member 211 abuts against the upper surface 1111 of the stopping protrusion 111, so that the connecting portion 21 is limited and maintained at the upper end position in the cavity 11 without up-and-down shaking. When the connecting portion 21 slides downward in the cavity 11 due to an external force (e.g., gravity applied to a horizontal bar when a person uses the horizontal bar) applied to the movable member 2, the elastic limiting member 211 is bent and deformed, so that the downward sliding motion of the connecting portion 21 is not prevented, and the elastic limiting member 211 stores elastic potential energy (i.e., energy is stored) due to the bending deformation. When the external force acting on the movable member 2 is removed, the elastic stopper 211 releases energy (i.e., releases the aforementioned accumulated elastic potential energy) to return the connection portion 21 upward to the initial installation state.
The lower surface 2111 of the elastic stopper 211 is a slope structure inclined upward from the movable part 2 to the fixed part 1, and the upper surface 1111 of the stopper protrusion 111 is a slope structure inclined downward from the fixed part 1 to the movable part 2. By such a design, it is easier to ensure that the connecting portion 21 makes the lower surface 2111 of the elastic limiting member 211 enter the upper surface 1111 of the stopping protrusion 111 to abut against and cooperate with the upper surface 1111 when being installed in the cavity 11.
The elastic limiting member 211 is an elastic sheet-like or plate-like structure, one end of the elastic limiting member is connected to the connecting portion 21, and the lower surface 2111 of the other end abuts against the upper surface 1111 of the stopping protrusion 111, and the size of the portion 211a of the elastic limiting member 211 abutting against the stopping protrusion 111 is smaller than that of the remaining portion 211b of the elastic limiting member 211. With such a design, the elastic limiting member 211 is more easily elastically deformed or the elastic deformation of the elastic limiting member 211 is increased, so as to improve the sliding stroke and reliability of the connecting portion 21.
The bottom wall of the concave cavity 11 is provided with a first slope surface 113 which inclines from top to bottom towards the connecting part 21, the connecting part 21 is provided with a second slope surface 212 which inclines from top to bottom towards the direction far away from the bottom wall of the concave cavity 11, and the second slope surface 212 is in sliding contact fit with the first slope surface 113, so that when the connecting part 21 slides downwards in the concave cavity 11, the fixing part 1 can move outwards to increase the friction force with the supported surface, and further can be firmly supported on the supported surface. The stopping protrusion 111 is convexly disposed on the first slope surface 113, the second slope surface 212 is concavely disposed with an avoiding groove 2121 for the stopping protrusion 111 to enter, and the elastic limiting member 211 is disposed in the avoiding groove 2121.
In addition, specifically, the elastic limiting member 211 is a cantilever structure extending from the bottom wall of the avoiding groove 2121 to the first slope surface 113, so that the elastic deformation capability of the elastic limiting member 211 can be further increased. The lower surface 2111 of the free end of the cantilevered structure abuts the upper surface 1111 of the stop protrusion 111, and the end 2110 of the free end of the cantilevered structure abuts the first ramp surface 212.
The first slope surfaces 113 have three and are continuously provided on the bottom wall of the cavity 11 in a step shape in the up-down direction. The second slope surfaces 212 are also provided in three numbers, and are continuously provided on the connecting portion 21 in a step shape in the up-down direction. The first slope surfaces 113 are parallel to each other, the second slope surfaces 212 are also parallel to each other, and the second slope surfaces 212 are in one-to-one corresponding sliding contact fit with the first slope surfaces 113.
The stopper protrusion 111 has two and is divided into two first slope surfaces 113 at the upper end and the lower end. The escape grooves 2121 are provided in two, and are respectively provided on the two second slope surfaces 212 at the upper end and the lower end. The two elastic stoppers 211 are respectively disposed in the corresponding avoiding groove 2121.
The bottom of each of the two side walls of the cavity 11 is provided with a slot 114, and the two sides of the connecting portion 21 are provided with an inverted buckle 213 for being clamped into the corresponding slots 114, so that the connecting portion 21 cannot be separated after being installed in the cavity 11.
As shown in fig. 7, this embodiment also provides an example of a horizontal bar, which includes a telescopic rod 3 and supporting seats 4 installed at two ends of the telescopic rod 3, where the supporting seats 4 are the horizontal bar supporting seats as described above.
The above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made in the claims and the description of the present invention are within the scope of the present invention.
