Description

Spring adjusting mechanism for spring bed net Technical Field The utility model relates to the technical field of spring bed nets, in particular to a spring adjusting mechanism for a spring bed net. Background The spring bed net is a core supporting structure in the spring mattress and is mainly made of high-carbon steel wires, and a net structure with inherent elasticity is formed by mechanical braiding or manual braiding. It has the functions of supporting body weight, dispersing pressure, and enhancing the elasticity and durability of mattress. The high-quality spring bed net has high rebound resilience, pressure resistance and good ventilation performance, is a key component for improving sleeping quality, and is widely applied to mattress products such as home, hotel, medical treatment and the like. The prior spring mattress has the following problems in structural design. For example, the overall support firmness of most mattresses is fixed and cannot be adjusted to individual needs. Meanwhile, the mattress is difficult to differentially support different parts of the body, and the local height and the hardness degree cannot be accurately adjusted. This results in a mattress that does not fit well around the body curve, affecting the comfort and sleep quality of the user. Although some mattresses with adjustable functions are already available on the market, the products are generally complex in structure, inconvenient in adjustment operation, lack of stable and effective limiting and positioning mechanisms, and are easy to cause loosening of the mattress structure or functional failure. Therefore, there is a need for a spring mattress adjustment mechanism that is more rational in construction and flexible in adjustment. The adjusting mechanism can conveniently adjust the overall hardness, and simultaneously support to finely control the local supporting height, so that the adjusting mechanism is better suitable for the body types and sleeping habits of different users, and the comfort and the fitting degree are improved. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present utility model is to provide a spring adjusting mechanism for a spring bed net, which can achieve individual adjustment of hardness and height of different parts of the bed net by adjusting positions of a pull rope and a hollow threaded rod, thereby improving use comfort and supporting effect. The spring adjusting mechanism for the spring bed net comprises a first spring, wherein the top of the first spring is fixedly connected with a fixed plate, the bottom of the fixed plate is provided with a pull rope, the bottom of the first spring is fixedly connected with a movable plate, the center of the top of the movable plate is fixedly connected with an internal thread cylinder, the bottom of the movable plate is provided with a spring fixing piece, the spring fixing piece and the top of the first spring are connected with adjacent springs through connecting springs, the internal threads of the internal thread cylinder are connected with a hollow threaded rod, one end of the bottom of the hollow threaded rod is rotatably arranged at the top of the spring fixing piece, and the pull rope penetrates through the hollow threaded rod. Preferably, the bottom of the spring fixing piece is rotatably provided with a C-shaped buckle, and the outer wall of the pull rope is provided with a plurality of limit knots which are equidistantly arranged. Preferably, the spring fixing piece comprises a cross plate, a bearing is fixedly connected to the top of the cross plate, one end of the bottom of the hollow threaded rod is fixedly connected to the inner ring of the bearing, four through holes are symmetrically formed in the top of the cross plate, and the connecting springs penetrate through the through holes. Preferably, the spring fixing piece comprises a disc, a bearing is fixedly connected to the top of the disc, a cross hoop is fixedly connected to the outer wall of the disc, one end of the bottom of the hollow threaded rod is fixedly connected to the inner ring of the bearing, and the connecting spring penetrates through the cross hoop. Preferably, a limiting block is arranged at one end of the top of the hollow threaded rod. Preferably, one end of the bottom of the hollow threaded rod is provided with a rectangular groove Preferably, the cross hoop is connected with the adjacent spring through a connecting spring. Compared with the prior art, the spring adjusting mechanism has the beneficial effects that when the spring adjusting mechanism is arranged in the spring bed net, a user can adjust the positions of the stay rope and the hollow threaded rod according to the self requirements, so that the individual adjustment of the hardness and the height of different parts of the bed net is realized, the structure is flexible to adjust,
