Technical Field

The invention relates to a cushion, in particular to a push-button cushion lifting device.

Background

Along with the continuous development of society and economy, the demand of people on vehicles is larger and larger, but the heights of people are different, and along with the increasing and increasing requirements on the lifting of a vehicle cushion, the vehicles using the cushion at present basically increase the sliding friction force in a pressure increasing mode to fix the height of the cushion; however, this method has disadvantages, such as a relatively long time for lifting, a fixed height of the seat cushion still not suitable for the height of the user, a large force consumption, etc.

Disclosure of Invention

The purpose of the invention is as follows: the invention provides a button type cushion lifting device, which aims to overcome the defects in the prior art.

The technical scheme is as follows: the invention relates to a push-button type cushion lifting device, which comprises a cushion and a multi-stage seat rod; the multistage sitting rod comprises a first-stage sitting rod, a second-stage sitting rod, a third-stage sitting rod and a fourth-stage sitting rod; the multistage seat rod is provided with a sliding ball, a spring and a rolling steel ball, the spring is transversely fixed in the multistage seat rod, the sliding ball is connected with the spring, the side surfaces of the upper ends of the second-stage seat rod, the third-stage seat rod and the fourth-stage seat rod are provided with sliding ball clamping openings, and the sliding ball is embedded in the sliding ball clamping openings; the lower end of the multi-stage seat rod is provided with a baffle plate, and the distance from the top of the lower-stage seat rod to the baffle plate is less than the distance from the bottom of the upper-stage seat rod to the slide ball bayonet; the rolling steel ball is positioned between the outer wall of the upper-level seat rod and the inner wall of the lower-level seat rod.

The cross section of the multi-stage seat rod is square.

The bottom end of the inner wall of the side surface of the multistage seat rod is provided with an inward protruding groove, and the rolling steel balls are positioned in the grooves. The second-level seat rod and the fourth-level seat rod are provided with sliding ball bayonets in the same side direction.

The direction of the third-stage seat rod for arranging the sliding bead bayonet is opposite to the direction of the second-stage seat rod for arranging the sliding bead bayonet.

Has the advantages that: the invention has the following advantages:

(1) the seat rod is connected in a multilayer mode, the built-in springs are connected with the sliding balls and connected into the seat rod, the seat rods in different levels are clamped in one section through the sliding ball clamping openings, the sliding ball clamping openings are arranged in different directions of the seat rod to reduce the influence of the gravity of a person on the seat rod, and a user can manually press the sliding balls and the seat cushion to achieve lifting of the seat cushion so as to meet the requirements of people with different heights;

(2) the cross section of the seat rod is quadrangular to ensure that the seat rod cannot rotate, so that the sliding balls of the seat rod pass through the bayonet position of the lower-level seat rod when the seat rod is pulled up;

(3) the rolling steel ball is attached to the groove in the lower end of the seat rod through grease, and then the original sliding friction is changed into rolling friction to reduce the influence of friction force on force applied by people, so that the seat rod is safer and better in controllability than an air pressure seat rod.

Detailed Description

As shown in fig. 1 and 2, the invention comprises a cushion 1, a first-stage seat rod 2, a sliding ball 3, an internal spring 4, a rolling steel ball 5, a second-stage seat rod 6, a seat rod groove 7, a third-stage seat rod 8, a fourth-stage seat rod 9, a sliding ball bayonet 10 and a plane baffle 11.

Each level of seat rod is provided with a sliding ball, a spring and a rolling steel ball, wherein the sliding ball 3 is connected with the built-in spring 4, and the whole body is transversely connected and fixed in the seat rod. The user presses the slide ball 3 in the slide ball bayonet 10 to compress the built-in spring 4, and then presses the seat cushion 1 to lower the seat cushion 1.

When a user wants to lift the seat cushion 1, the seat cushion 1 is pulled upwards, and when the user reaches a corresponding position, the sliding balls 3 can be clamped into the sliding ball clamping openings 10 of the next-stage seat rods under the stretching action of the built-in springs 4, so that the seat cushion is fixed. The pole of sitting of different grades passes through sliding ball bayonet socket 10, and a lesson blocks a lesson, and the sliding ball bayonet socket is laid and is reduced people's gravity and to sitting the influence of pole in the equidirectional not of sitting the pole, specifically as shown in figure 3, figure 4, and the bayonet socket of pole 6 is sat at No. 3 region b to the second grade, and the bayonet socket of pole 8 is sat at No. 1 region a to the third grade, and the bayonet socket of pole 9 is sat at No. 3 region b to the fourth grade, thereby the one-level separates the one-level and distributes 1, 3 regions to realize alleviating gravity on the. The sliding ball bayonets 10 are distributed on the upper part of the seat post.

The seat rod is designed to be quadrilateral so as to ensure that the seat rod which is taken in cannot rotate, and further, when the seat rod is pulled up, the sliding ball 3 of the seat rod passes through the sliding ball bayonet 10 of the seat rod at the next level, the rolling steel ball 5 and the seat rod groove 7 are in inscribed relation, the gap distance between the upper seat rod and the lower seat rod is the radius of the rolling steel ball 5, at the moment, the rolling steel ball 5 can realize free rolling between the seat rod groove 7 of the upper seat rod and the inner wall of the lower seat rod, and the phenomenon that the rolling steel ball 5 slides down cannot occur. The rolling steel balls 5 are attached to the seat rod groove 7 at the lower end of the seat rod through grease, the original sliding friction is changed into rolling friction to reduce the influence of friction force on the force applied by people, two rolling steel balls are designed on four surfaces of the lower portion of the seat rod as shown in figure 2, and the number of the sections of the seat rod is designed into a plurality of sections so as to meet the requirements of people with different heights.

The distance from the top of the sitting rod to the plane baffle 11 is less than the distance from the bottom of the upper sitting rod to the sliding ball bayonet 10, so that when the cushion is adjusted downwards, the sliding ball 3 of the upper sitting rod is clamped in the sliding ball bayonet of the lower sitting rod, and each sitting rod can be adjusted downwards normally. The function of the plane baffle is that the fixed seat rod does not descend any more.
