Example 1
Referring to fig. 1 to 4, the telescopic column 100 of the present embodiment includes an inner tube 10 and an outer tube 20 that are coupled to each other, and a locking mechanism that fixes the inner tube 10 and the outer tube 20 together. The inner tube 10 has an open end 110 inserted into the outer tube 20, and a strip-shaped opening 120 is provided in the side wall of the inner tube 10, the strip-shaped opening 120 extending longitudinally to the opening edge. The locking mechanism comprises a tensioning component for providing a tensioning force for expanding the opening end 110 outwards along the direction perpendicular to the length direction of the inner tube 10, and a matching component which is arranged on the inner tube 10 and matched with the tensioning component to tension the opening end 110, wherein the side walls of the inner tube 10 and the outer tube 20 are provided with operation holes corresponding to the tensioning component. Specifically, the inner tube is provided with an operation hole 101, and the outer tube 20 is provided with an operation hole 201.
The inner tube 10 and the outer tube 20 are square tubes, and in some embodiments, at least one strip-shaped opening 120 is formed on at least two surfaces of a side wall of the inner tube 10, and the at least two strip-shaped openings 120 divide the side wall of the opening end portion of the inner tube 10 into at least two side wall deformation portions. For example, at least one strip-shaped opening 120 is formed on two opposite surfaces of the sidewall of the inner tube 10, and the at least two strip-shaped openings 120 divide the sidewall of the opening end of the inner tube 10 into two sidewall deformation portions, and each of the two sides of each sidewall deformation portion includes a side edge divided by the strip-shaped opening 120. At least two strip-shaped openings 120 provided on opposite sides divide the side wall of the open end of the inner tube 10 into two U-shaped side wall deformations, each side wall deformation comprising a corner 170 on each side, each corner 170 comprising at least one of said sides.
In this embodiment, four sides of the side wall of the inner tube 10 are respectively provided with one strip-shaped opening 120, the four strip-shaped openings 120 divide the side wall of the open end of the inner tube 10 into two U-shaped side wall deformation parts, two sides of each side wall deformation part respectively comprise a corner 170, and each corner 170 comprises one side edge as shown in fig. 4. Of course, more than one strip-shaped opening 120 may be formed on any one of the four sides of the inner tube 10, and the side wall of the open end of the inner tube 10 may be divided into four corners 170.
Wherein the tensioning component is a screw 130, the matching component comprises a first elastic tensioning piece 140 and a second elastic tensioning piece 150 which are respectively fixed on two sides of the side wall of the opening end 11, the screw 13 is movably connected between the first elastic tensioning piece 140 and the second elastic tensioning piece 150 along the axial direction of the screw 13, and at least one of the first elastic tensioning piece 140 and the second elastic tensioning piece 150 is in threaded connection with the screw 130. For example, the first elastic tension member 140 and the screw 130 are abutted or fixed together, and the second elastic tension member 150 and the screw 130 are screwed. Alternatively, the second elastic tension member 150 is abutted against or fixed to the screw 130, and the first elastic tension member 140 is screwed to the screw 130. When the screw 130 is rotated, the portions of the first and second elastic tension members 140 and 150 that are in contact with the screw 130 are separated from or brought close to each other, respectively.
The two ends of the first elastic tension member 140 are respectively connected between the two corners 170 of the first sidewall deformation portion, and the two ends of the second elastic tension member 150 are respectively connected between the two corners 170 of the second sidewall deformation portion. In the present embodiment, as shown in fig. 3 and 4, the two ends of the first elastic tension member 140 are respectively connected to two adjacent corners 170 of the four corners 170, and the two ends of the second elastic tension member 150 are respectively connected to the other two adjacent corners 170 of the four corners 170. In order to increase the friction force between the inner tube 10 and the outer tube 20, the four corners 170 are further provided with wear-resistant members 171 for frictional contact with the inner wall of the outer tube 20, respectively, and the wear-resistant members 171 may be rubber blocks or rubber sleeves.
The first elastic tension member 140 includes first connection sections 141 located at both sides and respectively connected with two adjacent corners 170, and first elastic deformation sections 142 connected between the first connection sections 141 at both sides; the second elastic tension member 150 includes second connection sections 151 located at both sides and respectively connected with the other two adjacent corners 170, and second elastic deformation sections 152 connected between the second connection sections 151 at both sides. In the present embodiment, the first elastic deformation section 142 and the second elastic deformation section 152 are disposed opposite to each other and are respectively arched inward, and thus, the first elastic tensioning member 140 and the second elastic tensioning member 150 have an "M" shape in the present embodiment. The first and second elastically deforming sections 142 and 152 are each arc-shaped.
In order to enhance the elastic force and the service life of the first elastic tensioning member 140 and the second elastic tensioning member 150, the first elastic tensioning member 140 and the second elastic tensioning member 150 may be integrally bent by metal elastic sheets. The first and second connection sections 141 and 151 may be fixedly connected to the inner wall of the inner tube 10 by welding, clamping or bolts.
In this embodiment, the first end of the screw 130 is threaded and passes through the arched top of the first elastically deforming section 142 of the first elastic tensioning element 140, and the second end of the screw 130 abuts against the arched top of the second elastically deforming section 152 of the second elastic tensioning element 150. An internal screw 160 is fixed to the first elastic deformation section 142, and a first end of the screw 130 is screwed and passes through the internal screw 160. An operation portion, specifically, an inner hexagonal hole 131 is formed at a first end portion of the screw 130. When the first end of the screw 130 is aligned with the operation hole 201 of the outer tube 20, the screw 130 is operated to be rotated by inserting an allen wrench into the operation hole 201 of the outer tube 20 opened corresponding to the screw 130.
When the screw 130 rotates forward, the force of the second end portion against the second elastic tensioning member 150 is continuously increased, the first elastic deformation section 142 and the second elastic deformation section 152 are relatively abutted, at this time, the radian of the first elastic deformation section 142 is reduced, and the first connection sections 141 on two sides tend to straighten, so that the first connection sections 141 on two sides are separated from each other to open, and the two corners 170 of the corresponding U-shaped first side wall deformation part are driven to open relatively to be tightly attached to the inner wall of the outer tube 20; meanwhile, the radian page of the second elastic deformation section 152 becomes smaller and tends to straighten, so that the second connection sections 151 at two sides are separated from each other to open, and the two corners 170 of the corresponding U-shaped second side wall deformation part are driven to open relatively to be close to the inner wall of the outer tube 20, thereby achieving the effect that the four corners 170 are opened outwards along the axial direction perpendicular to the screw 130 to be close to the inner wall of the outer tube 20, and then the opening end 110 of the inner tube 10 is expanded and the outer tube 20 is close to be fixed together.
When the screw 130 rotates reversely, the force of the second end portion against the second elastic tensioning member 150 is continuously reduced until the second end portion is separated from the second elastic tensioning member 150, so that the mutually-abutting force between the first elastic deformation section 142 and the second elastic deformation section 152 is reduced until the abutting force is eliminated, at this time, the first elastic deformation section 142 tends to bend and return to a natural bending state under the self elastic force, so that the first connection sections 141 on two sides are mutually closed and reset, and the two corners 170 of the corresponding U-shaped first side wall deformation part are relatively closed and separated from the inner wall of the outer tube 20; meanwhile, the second elastic deformation section 152 tends to bend and return to a natural bending state under the self elastic acting force, so that the second connection sections 151 at two sides are close to each other and reset, and the other two corners 170 of the corresponding U-shaped second side wall deformation part are relatively close to separate from the inner wall of the outer tube 20, thereby achieving the effect that the four corners 170 are contracted inwards along the axial direction perpendicular to the screw 130 to separate from the inner wall of the outer tube 20, and the inner tube 10 and the outer tube 20 are separated and can relatively slide along the length direction to adjust the telescopic length of the inner tube and the outer tube.
In this embodiment, in order to facilitate positioning when adjusting the telescopic position of the inner tube, the inner tube 10 is further provided with an elastic positioning member, the elastic positioning member includes a pin shaft 190 and a spring 200, the spring 200 and the pin shaft 190 are mounted on a guide seat fixed in the inner tube 10, a through hole is formed in a side wall of the inner tube 10, one end of the pin shaft 19 is provided with a positioning convex portion 191 movably disposed in the through hole of the inner tube 1 and protruding outwards, and a positioning hole matched with the positioning convex portion 191 is formed in a side wall of the outer tube 20.
The locking mechanism further comprises a housing 210 sleeved on the opening of the outer tube 20, and a positioning auxiliary hole 211 for accommodating the positioning protrusion 191 is formed on the housing 210 corresponding to the positioning hole. The casing 210 is provided with an operation auxiliary hole corresponding to the operation hole 201 of the outer tube 20. The housing 210 is further provided with a button 213 for pressing the inward retraction of the driving detent projection 191.
When the inner tube 10 and the outer tube 20 are locked, the inner tube 10 and the outer tube 20 are adjusted to proper lengths, and the positioning convex parts 191 of the pin shafts 190 are ejected from the inner tube 10 and clamped into the positioning auxiliary holes 211. Then, when the screw 130 is screwed down, the force of the screw 130 against the second elastic tension member 150 becomes large by penetrating the operation auxiliary hole on the housing 210, the operation hole 201 on the outer tube 20 and the operation hole 101 on the inner tube 10 in order with the socket head cap wrench, both the first elastic tension member 140 and the second elastic tension member 150 tend to straighten, and the four corners 170 of the open end portion of the inner tube 1 are expanded outward, so that the inner tube 10 and the outer tube 20 are pressed and fixed together.
When the screw 130 is unscrewed during the operation of unlocking the inner tube 10 and the outer tube 20, the force of the screw 130 against the second elastic tensioning member 150 is reduced, the abutting force between the first elastic tensioning member 140 and the second elastic tensioning member 150 is reduced, the opening end of the inner tube 10 is actively retracted inwards from expanding, the pressing force between the inner tube 10 and the outer tube 20 is reduced, and at the moment, the button 213 is pressed down, so that the positioning convex part 191 of the pin shaft 190 is retracted into the inner tube 10 from the positioning auxiliary hole 211, and the inner tube 10 and the outer tube 20 can be telescopically adjusted.
A plurality of positioning holes and a plurality of operation holes 201 can be further arranged on the outer tube 20 along the length direction thereof, so as to adapt to positioning of the inner tube 10 and the outer tube 20 in a plurality of different telescopic lengths. The inner tube 10 and the outer tube 20 can be contracted to the minimum or can be disassembled during transportation, reducing the packaging length.
The diameter of the screw 13 should be larger than the diameter of the operation hole 101 on the inner tube 10 to avoid the screw 130 from coming out therefrom. In order to avoid misoperation, an end cover 214 for blocking the operation hole 201 is also arranged on the shell 210.
After the telescopic upright 100 of this embodiment is stretched to the longest length, the elastic positioning piece (the pin shaft 190 and the spring 200) is used to position the inner tube 10 and the outer tube 20, and then the tool is threaded into the locking mechanism to twist the screw 130 so that the open end 110 of the inner tube 10 expands outwards, and the open end 110 of the inner tube 10 is pressed against the outer tube 20 after being expanded, so that the inner tube 10 and the outer tube 20 are tightly attached and fixed together, the structure of the telescopic upright 100 is more stable, the bearing capacity is larger, and the telescopic upright can be ensured to have a more stable supporting effect. When the telescopic upright 100 is in use, the outer tube 20 can be supported on the ground, and the inner tube 10 is positioned above; alternatively, the inner tube 10 may be supported on the ground and the outer tube 20 may be positioned above.
Example two
The structure of the telescopic column of this embodiment is basically the same as that of the first embodiment, except that: the two end portions of the screw 130 are respectively screwed with the first elastic tension member 140 and the second elastic tension member 150, an internal screw member 160 is respectively provided on the first elastic tension member 140 and the second elastic tension member 150, and the screw direction of the screw threads on the two end portions of the screw 130 is opposite as shown in fig. 5. When the screw 130 is rotated in the forward direction, the first and second elastically deforming sections 142 and 152 are relatively tightened, so that the four corners 170 are each outwardly opened in the axial direction perpendicular to the screw 130 against the inner wall of the outer tube 20, and the open end 110 of the inner tube 10 is expanded and the outer tube 20 is tightly fixed together. When the screw 130 rotates reversely, the force of the first elastic deformation section 142 and the second elastic deformation section 152 against each other becomes smaller, and the four corners 170 are contracted inward in the axial direction perpendicular to the screw 130 and separated from the inner wall of the outer tube 20, so that the inner tube 10 and the outer tube 20 are separated and the telescopic length of the two can be adjusted by sliding relatively in the length direction.
