Abstract
The utility model discloses an air pressure ball net lifting device which comprises an air cylinder. A second piston is arranged in the air cylinder, the second piston enables the air cylinder to be divided into a first air chamber and a second air chamber, a first piston is arranged at the upper end of the air cylinder, a first check valve is arranged at the upper end of the air cylinder, a second check valve is arranged on the side portion of the lower end of the air cylinder, a third air chamber is formed between the side portion, where the second check valve is located, of the air cylinder and the first piston, and a pedal is connected to the position of the top of the first piston. According to the air pressure ball net lifting device, the rising, stopping and falling movements of a ball net can be adjusted through movements of the pistons, and therefore the height of the ball net can be adjusted conveniently and accurately.
Description
Technical field
The utility model relates to a kind of pressure liftable net assembly.
Background technique
Net mainly comprises volleyball net, badminton net etc.But the lifting process of current net when regulating height mainly has manually and complete, and the efficiency of manual tune is lower like this, speed is slow, after secondly regulating, the insufficient height of net is accurate, can affect like this training or competition effect.
Model utility content
The utility model, for the deficiencies in the prior art, provides a kind of pressure liftable net assembly, and this pressure liftable net assembly can regulate the height of net easily and accurately.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of pressure liftable net assembly, comprise cylinder, described cylinder interior is provided with the second piston, described the second piston is divided into the first air chamber and the second air chamber by cylinder, described cylinder upper end is provided with first piston, and described cylinder upper end is provided with the first one-way valve, and described cylinder lower end sidepiece is provided with the second one-way valve, between the sidepiece of described the second one-way valve place cylinder and first piston, form the 3rd air chamber, place, described first piston top is connected with foot-operated.
In technique scheme, described cylinder outside is arranged with supporting sleeve.
In technique scheme, described first piston top links together by bearing pin with foot-operated.
Beneficial effect: compared with prior art, it has following beneficial effect to the utility model:
The motion that pressure liftable net assembly of the present utility model can regulate net to rise, stop, declining by the motion of piston, thus the height of net can be regulated easily and accurately.
Accompanying drawing explanation
Fig. 1 is pressure liftable net assembly structural representation.
Embodiment
Participate in Fig. 1, a kind of pressure liftable net assembly, comprise cylinder 1, described cylinder 1 inside is provided with the second piston 2, and described the second piston 2 is divided into the first air chamber 1a and the second air chamber 1b by cylinder 1, and described cylinder 1 upper end is provided with first piston 3, described cylinder 1 upper end is provided with the first one-way valve 4, described cylinder 1 lower end sidepiece is provided with the second one-way valve 5, forms the 3rd air chamber 1c between the sidepiece of described the second one-way valve 5 place cylinders 1 and first piston 3, and described first piston 3 3a places, top are connected with foot-operated 6.
Described cylinder 1 outside is arranged with supporting sleeve 7, like this regulating during net height, and can be more stable.
Described first piston 3 top 3a link together by bearing pin 8 with foot-operated 6, foot-operated 6 can rotate more flexibly like this.
When depressing foot-operated 6, first piston 3 up moves, and the first air chamber 1a is identical with the second air chamber 1b, according to pascal's principle, obtains, and the gas of the second air chamber 1b moves toward the first air chamber 1a, realizes the motion that cylinder 1 rises.
When unclamping, ride 6, first piston 3 gets lodged on the connection mouth of the first air chamber 1a and the second air chamber 1b, and the first air chamber 1a and the second air chamber 1b separate, and realize the out-of-work state of cylinder 1.
When opening the first one-way valve 4, according to pascal's principle, because the air pressure of the first air chamber 1a is greater than the air pressure of the 3rd air chamber 1c, the gas in the first air chamber 1a moves to the 3rd air chamber 1c, realizes cylinder 1 descending motion.
Complete when declining, while continuing to rise, because can making the air pressure of the second air chamber 1b, rising reduces, when the draught head of the second air chamber 1b and the 3rd air chamber 1c reaches certain difference, the second one-way valve 5 opens that (wherein the first one-way valve 4 is by switch opens, poor the opening of the second one-way valve 5 depended on pressure), gas in the 3rd air chamber 1c moves to the second air chamber 1b, the gas of the second air chamber 1b is because ascending motion is moved to the first air chamber 1a, therefore so circulation realizes the rising of cylinder 1, the motion requirement that stops, declining, thereby regulates easily and accurately the height of net.
In sum, the motion that the utility model pressure liftable net assembly can regulate net to rise, stop, declining by the motion of piston, thus can regulate easily and accurately the height of net.
Embodiment recited above is described preferred implementation of the present utility model, not design of the present utility model and scope is limited.Do not departing under the prerequisite of the utility model design concept; various modification and improvement that related domain ordinary person makes the technical solution of the utility model; all should drop into protection domain of the present utility model; the technology contents of the utility model request protection, has all been documented in claims.
