Abstract
The utility model relates to an adjustable bottom foot which is characterized by comprising an upper cover and a bottom cover. The upper cover is arranged on the upper portion of the bottom cover and encloses the bottom cover. A cavity body is formed between the upper cover and the bottom cover. A torsional spring is arranged inside the cavity body. The upper cover and the bottom cover are connected together by the torsional spring. A fastening screw sequentially penetrates through the bottom cover and the upper cover along the axial direction. A threaded rod of the fastening screw stretches out of the upper cover to the exterior. The upper cover is connected with the fastening screw through a clamping spring. An adjusting mechanism used for adjusting the relative height between the upper cover and the bottom cover is arranged inside the cavity body. The adjustable bottom foot has the advantages of being rapid in connection, simple in operation, good in stability, high in safety, strong in appearance integrity, low in cost, uneasy to damage and suitable for various occasions and environments. Besides, influences of external forces on the adjustable bottom foot are small.
Description
Technical field
The utility model relates to a kind of adjustable bottom feet for desk and other furniture.
Background technology
When desk or other furniture used in different occasions, often meeting because ground is uneven, make desk steady not, cause unnecessary trouble to the user, therefore at desk bottom installation adjustable bottom feet, can make desk steady by the adjusting bottom height.Existing adjustable bottom feet has following several types, and its pluses and minuses are respectively:
Screw thread manual adjustments footing is the height of regulating Leg support for furniture by screw-in or the back-out of screw thread.Its advantage is that to regulate rear smoothness high, and each footing is stressed comparatively even, but regulate very inconvenient, mobile if the desk the restaurant in often needs, regulate very bothering.
Gas bag formula footing has added the air bag in footing inside, can automatically shrink after gas bag is stressed, automatically regulates the Leg support for furniture height with this.The footing of the type is regulated more convenient, in case but after automatically adjusting, furniture is subject to external pressure, after the stressed increase of gas bag, still can further shrink, and cause furniture to tilt.If when being subjected to external impacts, tilting can be apparent in view; And each footing unbalance stress, easily cause the furniture distortion even to damage; Be subjected to the impact of air pressure, adjustable range is less; Gas bag is fragile when iterative cycles is stressed.
Plastics spring formula footing, plastics spring is stressed can be shunk automatically, automatically regulates the Leg support for furniture height with this.The footing of the type is regulated more convenient, but is subjected to the impact of coefficient of elasticity, and adjustable extent is less, and in a single day furniture be subject to external impacts, and spring meeting natural shrinking causes furniture to tilt so that distortion even damages.
Swinging the rod-type footing, is that swing by threaded rod reaches and regulates the Leg support for furniture height.The mechanism of oscillating rod type is easy to adjust, but less stable easily deforms when being subjected to external impacts, damages.
Summary of the invention
For overcoming the defective of prior art, the utility model provides a kind of adjustable bottom feet.The technical solution of the utility model is: a kind of adjustable bottom feet, it is characterized in that: comprise upper cover and bottom, described upper cover is arranged on the top of bottom, and bottom is surrounded, and form cavity between bottom, in described cavity, torsion spring is installed, this torsion spring links together described upper cover and bottom, trip bolt passes bottom and upper cover vertically successively, its screw rod passes upper cover to outside, described upper cover is connected with trip bolt by jump ring, also is provided with the guiding mechanism of adjusting relative altitude between upper cover and bottom in described cavity.
Described guiding mechanism is upper cover slide block and the bottom slide block that is separately positioned on upper cover and bottom, is slidably matched between described upper cover slide block and bottom slide block, and its mating surface is the inclined-plane.
Described upper cover slide block and bottom slide block are at least two pairs, evenly arrange along trip bolt.
Be provided with the termination plug on described bottom, corresponding with described trip bolt.
The utility model has the advantages that: have advantages of connect quick, simple to operate, be subjected to that external force affects little, good stability, safe, overall appearance strong, cost is lower, not fragile, be fit to various occasions and environment.
Description of drawings
Fig. 1 is agent structure schematic diagram of the present utility model;
Structural representation when Fig. 2 is the utility model upper cover slide block and the cooperation of bottom slide block;
Fig. 3 is the structural representation that in Fig. 2, upper cover slide block and bottom slide block relatively move.
The specific embodiment
Referring to Fig. 1, the utility model relates to a kind of adjustable bottom feet, comprise upper cover 3 and bottom 5, described upper cover 3 is arranged on the top of bottom 5, and bottom 5 is surrounded, and form cavity between bottom 5, torsion spring 4 is installed in described cavity, this torsion spring 4 links together described upper cover 3 and bottom 5, trip bolt 1 passes bottom 5 and upper cover 3 vertically successively, the screw rod of trip bolt passes upper cover 3 to the outside, and described upper cover 3 is connected with trip bolt 1 by jump ring 2, also is provided with the guiding mechanism of adjusting relative altitude between upper cover 3 and bottom 5 in described cavity.
Referring to Fig. 2 and Fig. 3, described guiding mechanism is upper cover slide block 7 and the bottom slide block 8 that is separately positioned on upper cover 3 and bottom 5, be slidably matched between described upper cover slide block 7 and bottom slide block 8, its mating surface is the inclined-plane, described upper cover slide block 7 and bottom slide block 8 are at least two pairs, evenly arrange along trip bolt.
Be provided with termination plug 6 on described bottom 5, corresponding with described trip bolt 1.
The utility model is arranged on furniture by trip bolt of the present utility model when in use, only needs during installation to arrest upper cover with hand, the screw portion of trip bolt is screwed in furniture can realize installation of the present utility model, does not need any instrument.The gravity of furniture and extraneous pressure pass to upper cover by trip bolt and jump ring, and upper cover passes to bottom to power, the direct kiss the earth of bottom or workbench by the inclined-plane that cooperatively interacts with bottom.After installation, as the ground out-of-flatness, only need gently make furniture produce the tendency of rotation with hand, the inclined-plane of upper cover and bottom can produce and relatively move under the effect of slight outer moment of torsion this moment, until a plurality of footing is stressed even.In case adjust completely, furniture is subject to any pressure and impact again, and the inclined-plane of upper cover and bottom can not produce and relatively move.
For the utility model, the angle on inclined-plane is crucial, the size of angle is relevant with the coefficient of friction of material, as long as angle is controlled in rational scope, add how much external force and all can be decomposed by the inclined-plane on furniture, the component of parallel-slope is as long as just guaranteed the stability of footing less than the frictional force of vertical inclined-plane component generation.Can automatic spring when torsion spring guarantees that the utility model is not stressed, simultaneously the coefficient of friction of upper cover and bottom carried out effective compensation, simultaneously, for different use occasions and environment, can select the different manufacture of materials.
