Abstract

The utility model discloses a foldable and height-adjustable table tennis table with a latching device and a lifting device. As is shown in the pictures, table legs are installed at the middle parts of two table-top boards. The table legs are connected by a quadrilateral support formed through combination of connecting rods. The table legs installed at the middle parts of the table-top boards make the two sides of each table-top board balanced in weight. The rhombus quadrilateral support enables the table legs to be unfolded or folded in parallel stably without falling. As for manual handles (20) installed at the middle of the rhombus quadrangle, when the table descends, a hole at one side of each hinge is automatically latched with a hook of a corresponding manual handle. To make table-tennis playing convenient for children, a height fixing sleeve (23, 23') is arranged additionally on each table leg to adjust the height of the table leg so that the height of the table tops can be adjusted. The connecting rods (4, 4') are used and a top tension force generated when the table tops are folded enables the table legs to ascend so that a problem that after the table tops are adjusted to be lower, the table legs are not high enough when the table is folded is solved. Turning damping rods (15, 15') and damping springs (16, 16') are arranged additionally between the table legs and the table tops so that operations in unfolding and folding of the table tennis table are easier and safer.

Description

A kind of ping-pong table that can fold energy lifting with locker and lowering or hoisting gear

Technical field:

The present invention relates to a kind of Foldable table tennis table, especially a kind of outer fold-type Foldable table tennis table.During expansion, when two desktops become horizontal positioned (use state) folding at the bottom of two desktops relative thirty years of age (folded state)

Background technology:

Table tennis is all-ages sports, in China, there is mass foundation widely, continuous quickening along with people's life and work rhythm, the effective time of taking exercises to gymnasium is less, in addition, the child of 5 to 6 years old practises playing table tennis from little just beginning, for their physical and mental health and standby talent's choice, will be very useful.At home a standby ping-pong table that can fold, again can lifting is a good selection, but existing folding ping-pong table supporting mechanism design is loaded down with trivial details, unfolded is harder, there is no elevating function, be unfavorable for child's operation and use, and fold mechanism exposes, place rear floor space and space larger, inconvenience is used in family.

The present invention is current condition and proposing Given this, and ball table launches and be folding easily simple, also has elevating function simultaneously, is suitable for adult's motion, is also suitable for child's motion.After folding, outwardly, in the middle of supporting mechanism is sandwiched in, appearance is smooth attractive in appearance for two desktops, and floor space is little, and adult child can safety operation.

Summary of the invention:

In order to reach above-mentioned purpose, have following problem to need to solve:

1, ball table can easily launch and fold, and guarantees the stable of desktop and table leg, can not produce and topple over.

2, ball table desktop is heavier, launches or has certain inertia when folding, for the sake of security, should have the setting that slows down desktop velocity of rotation.

3, after ball table folds, there is no, under External Force Acting, to keep stable state.

4, after ball table folds completely, it is very near that two desktop table legs lean on, and now must guarantee the stable of desktop.

5, ball table can lock the collision in the time of should not moving after launching and be out of shape.

6, desktop lifting should facilitate, and does not answer desktop lifting and to affect ball table folding.

The scheme overcoming the above problems is:

1, under each piece desktop centre, two table legs are installed, as shown in Figure 7: the weight balancing that makes same desktop both sides, the power more slightly at desktop two ends, just can make table tennis desktop fold or launch, ping-pong table is when folding and expansion, and four table leg all-the-time stable are to realize the folding key of ping-pong table vertically downward.In Fig. 2, table tennis desktop (1, 1 '), upper table leg (2, 2 '), lower table leg (3, 3 '), connecting rod (4, 4 ', 5, 5 ', 6, 7), rod hinge connection pin (9, 9 ', 10, 10 ', 11, 11 ', 12, 12 '), hollow hinged cover (13), height slip cap (14, 14 '), it is characterized in that, by upper table leg (2, 2 '), lower table leg (3, 3 ') connecting rod (4, 4 ', 5, 5 ') triangle and the connecting rod (4 that surround, 4 ', 5, 5 ', 6, 7) rhombus surrounding is by rod hinge connection pin (9, 9 ', 10, 10 ', 11, 11 ', 12, 12 ') and hollow hinged cover (13) and height slip cap (14, 14 '), the folding stand being combined into, symmetrical two parts are relied on mutually, solved four table leg all-the-time stable problem vertically downward.

2, for desktop, may rotate too fast problem, between desktop and table leg, set up break-in damper rod (15, 15 ') and damping spring (16, 16 '), upper table leg (2, 2 '), lower table leg (3, 3 '), table leg hinged seat (8, 8 ') mobile universal wheel (17, 17 '), band curved rod (4, 4 ', 5, 5 '), it is characterized in that, break-in damper rod (15, 15 ') fix with the relative position of desktop, with desktop, rotate, table leg hinged seat (8, 8 ') be located at table tennis desktop (1, 1 ') centre, damping spring (16, 16 ') one end is connected on damper rod, the other end is connected on upper table leg, as shown in Fig. 2 left side, at left side desktop, now damping spring (16) has a counterclockwise moment of torsion to desktop, when desktop folds into Fig. 9 position from Fig. 8, desktop is produced again to a clockwise moment of torsion, right side is just in time contrary, thereby play the effect that slows down desktop velocity of rotation.

3, when desktop is about to all fold, the weight of desktop is by connecting rod (4,4 ', 5,5 ') bear, if connecting rod (4,4 ', 5,5 ') make directly, when folding into position shown in Fig. 9, connecting rod (4,4 ') and connecting rod (5,5 ') have an angle that is less than 180 degree in rod hinge connection pin (10,10 ') intersection, under the effect of desktop gravity, desktop has the power of a slight outward spreading.In order to prevent this from occurring, connecting rod (4,4 '), connecting rod (5,5 ') are made a call to 3.7 ° of foldings at lead-in wire indication place, make their loading angles in intersection be slightly larger than 180 degree, thereby keep the stable of folding rear desktop.

4, in order to guarantee the stability after desktop folds completely, allow the wheel under each table leg choose certain distance to both sides, also have the wheel of choosing inwards, the wheel of choosing inwards can avoid table leg to produce moment of flexure simultaneously, prevent that desktop from producing excessive resistance when lifting.The wheel of outwards choosing is to choose below from desk, and the prerequisite that realizes this point is that the clear height of table leg (removing the height of universal wheel) is greater than half of a width of ping-pong table (137cm), i.e. 68.5cm.Otherwise the wheel of outwards choosing just can not be chosen below from desk.The top tension that this device utilizes connecting rod (4,4 ', 5,5 ') to produce when folding is pulled open the distance between upper table leg (2,2 ') and lower table leg (3,3 '), thereby has realized the target that wheel is chosen below desk.

5, after ball table launches, keeping desktop stable is also the problem that will solve, and uses hollow hinged cover (13) in intermediate connecting rod rotation place for this reason, middle through snap close turning cylinder (19) at hollow hinged cover.As the enlarged drawing of Fig. 2, like this, the shearing force of connecting rod (6,7) is born by hollow hinged cover (13), and snap close turning cylinder (19) just can easily rotate.Manually (20) are arranged on snap close turning cylinder (19), when desktop is deployed into certain position, desk connection hinge (22 ') with manually (20) are collided, under the effect of latch spring (21), manually just can snap close (20) and ball table connection hinge (22).

6 if the height of lifting desk surface only need arrive position as shown in Figure 8 foldable table top, manually adjusts height fixed cover (23,23 '), the manual fastening screw of hand-tight make-up (24,24 ') after putting in place.Because the upper table leg that square tube is made (2,2 ') is enclosed within on lower table leg (3,3 '), in the top of upper table leg and the bottom of lower table leg, leave the position of identical lifting distance, because desktop is heavier, in order to make desktop lifting easy and convenient, the table leg inner spring (25,25 ') of corresponding coefficient of elasticity is set in table leg.Make most weight pass to lower table leg (3,3 ') by spring upper, thereby disperseed the pressure on connecting rod.In spring, insert spring interpolation pole (26,26 '), upper end is connected with rod hinge connection pin (9,9 '), and other end seat is in the bottom of lower table leg, and its effect is while preventing spring-compressed, and spring gives a discount.

This invention is compared with existing folding ping-pong table, has simple to operate, easy to usely, and ball table launches locking as switch gate, two manually (20) with a snap close turning cylinder (19) connection, while opening, people on which limit can operate.Do not increasing under more facilities, considering that child is from the little needs that start to play table tennis, ping-pong table has increased again liftable function.Heave amplitude can freely be adjusted between 76cm～60cm, and after mixing up, within a period of time, desktop launches and be folding all without adjusting height.After child's stature grows tall, in the time that height of table top need to being adjusted, repeat above-mentioned action.After ping-pong table is folding, guarantee that the stable of it can have several different methods, relatively simple method is to set up a hook, and this invention is connecting rod (4,4 '), and (5,5 ') is once curved at lead-in wire indication place, more simple and direct after folding.Due to the universal wheel of installing under table leg all the time vertically downward, no matter ball table is to launch or folding, can move easily.In addition, ping-pong table overall setup is relatively simple, and manufacturing cost is also relatively low.
