Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.
Referring to the attached drawing 1, the attached drawing shows the utility model provides a novel scalable horizontal bar, including outer tube 1, inner tube 2, screw rod 3 and locating piece 4, inner tube 2 is two, and the setting of symmetry is in outer tube 1 to by the direction of outer tube 1, the one end of inner tube 2 stretch out outer tube 1 and with 4 fixed connection of locating piece, the tip of the other end inwards extends there is dog 21, is provided with the external screw thread on the dog 21, screw rod 3 set up in outer tube 1 and with the screw-thread fit, the both ends of screw rod 3 all are provided with dog 31, and dog 31 and dog 21 are spacing mutually after 2 outside removals of inner tube.
The theory of operation of this kind of horizontal bar is as follows, it is to be located the normal condition, and inner tube 2 contracts in outer tube 1, when needs carry out the horizontal bar support, directly rotates inner tube 2, through inner tube 2 and 3 direct threaded connection of screw rod, two inner tubes 2 are outwards stretched out, directly withstands the door frame position, and locating piece 4 is with firm the fixing on the door frame of whole horizontal bar, and the people just can move on the horizontal bar, and the intensity of whole horizontal bar has been guaranteed in the shaft hole cooperation of outer tube 1 and inner tube 2.
When the movement is finished or the door frame needs to be moved to other door frames, the contraction of the whole horizontal bar is realized by rotating the inner pipe 2, and the contracted horizontal bar is portable and convenient.
In addition, because the telescopic horizontal bar has a certain length requirement, if the telescopic horizontal bar extends beyond the original design range, danger is generated, therefore, in the embodiment, the stop blocks 31 are arranged at the two sides of the screw rod 3, when the inner tube 2 rotates, the stop heads 21 move outwards along the axis and collide with the stop blocks 31, and then the inner tube 2 is limited to move continuously, so that the user is prevented from installing the horizontal bar at the position beyond the limit.
For the stability of further promotion horizontal bar, can not lead to horizontal bar length change to produce the risk because of the mistake is rotatory promptly, in this embodiment, the middle part of screw rod 3 is provided with polished rod portion 32, polished rod portion 32 is provided with the first through-hole that link up, outer tube 1 corresponds the middle part and is provided with the second through-hole, still is provided with the round pin on the horizontal bar, the round pin passes second through-hole and first through-hole.
Specifically, when the pin is inserted into the first through hole and the second through hole, the screw rod 3 is firmly positioned, axial movement and radial rotation cannot be generated, and the positioning block 4 is more stably fixed on the doorframe.
In this embodiment, the end of the positioning block 4 is provided with a friction surface matched with the door frame, and the friction surface provides a larger friction force with the door frame, so that the positioning block 4 is fixed more firmly, and the use safety is ensured.
Furthermore, because the user has a downward pulling force when using the horizontal bar, in order to further promote the fastness, the fitting surface of locating piece 4 and door frame is the inclined plane, and the tip on inclined plane is down, and this kind of design not only provides frictional force, also has an inward pressure simultaneously, has guaranteed the firm fixed of whole horizontal bar.
In this embodiment, the matching portion of the positioning block 4 and the inner tube 2 is provided with a rotating portion convenient for hand rotation, the rotating portion is provided with a holding groove convenient for holding, and the holding groove matches with the hand to hold, so that the whole positioning block 4 can be rotated more easily.
In this embodiment, dog 31 is the nut, the screw rod 3 both ends extend out little screw thread section, and the nut is revolved admittedly on little screw thread section, and the setting of nut has realized dog 31 removable adjustable, can not directly cause the damage of whole horizontal bar because dog 31 damages.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
