Description

Technical Field

[0001] The utility model belongs to the technical field of vibration reduction, and in particular relates to a semi-enclosed composite spring vibration damper. Background Art

[0002] At present, effective vibration reduction methods must be adopted during the construction of air-conditioning units to prevent damage to the units caused by vibrations generated later. Most of the time, vibration absorbers are installed on the air-conditioning units.

[0003] Existing shock absorbers have the following defects during use: 1. Air-conditioning units are generally installed outdoors and are affected by the external environment for a long time, which makes them prone to rust and damage, shortening their service life, or requiring regular maintenance, which has high maintenance costs; 2. Shock absorbers are generally made of rigid materials, which make loud noises during operation. At the same time, due to their own weight, shock absorbers made of rigid materials are less convenient to install; 3. The existing shock absorber spring is installed inside it, which makes it difficult to observe the working condition of the spring and subsequently adjust the spring force; those skilled in the art urgently need to solve this technical problem.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] like Figure 1-6 As shown, the present invention provides a semi-enclosed composite spring shock absorber, comprising a support portion 1 made of nylon material;

[0033] a vibration-damping portion 2 , which is mounted on the supporting portion 1 and is made of a rigid material;

[0034] The protective portion 3 is sleeved on the vibration-damping portion 2 and built into the supporting portion 1. The protective portion 3 is made of nylon;

[0035] in,

[0036] The support portion 1 includes an ear plate 11, a slide 12 disposed on the ear plate 11, and a spring seat 13 disposed on the ear plate 11 and built into the slide 12. The slide 12 is configured as a rectangular structure with an open top, and a first through slot is formed on one side of the slide 12.

[0037] The vibration damping part 2 includes a spring body 21 installed in the spring seat 13. The spring body 21 protrudes from the upper end surface of the slide 12 and is covered with a spring cover 22. A screw 23 is passed through the middle of the spring cover 22 and is locked to the spring cover 22 by a first bolt 24.

[0038] The protection portion 3 includes a protection plate 31 and a sliding sleeve 32 disposed at the lower end of the protection plate 31. The sliding sleeve 32 is configured as a rectangular structure with an open lower end. The spring body 21 is sleeved on the sliding sleeve 32 and is placed in the sliding seat 12. A second through-slot corresponding to the first through-slot is defined on the sliding sleeve 32.

[0039] The protective plate 31 is provided with a hole for the screw 23 , and the screw 23 passes through the protective plate 31 and is locked on the protective plate 31 by a second bolt 25 ;

[0040] The working principle and beneficial effects of the above embodiment are as follows:

[0041] When the shock absorber is working, the spring body 21 is compressed or stretched based on the spring seat 13, and the sliding seat 12 and the sliding sleeve 32 cooperate to absorb and reduce vibration. Since the protective part 3 is sleeved in the supporting part 1, a good side force protection effect is formed between the two, thereby enhancing the stability of the shock absorber.

[0042] The support and protection parts of the utility model are made of reinforced nylon material, which does not make extra noise when the shock absorber is working. It also has the advantages of light weight, high strength and good sound absorption effect. The shock absorber of the utility model has the advantages of easy transportation and installation. In addition, the reinforced nylon material will not rust due to environmental reasons, thereby ensuring the durability and long-term stability of the shock absorber.

[0043] The utility model adopts a semi-enclosed structure, and the running state of the shock absorber spring can be well observed during use. At the same time, the protective part is sleeved in the supporting part, and the two have a good side force protection effect.

[0044] In one embodiment,

[0045] The support portion 1 and the protective portion 3 are integrally formed of nylon material. The sliding seat 12 is the same width as the ear plate 11, and the length of the sliding seat 12 is less than the length of the ear plate 11.

[0046] The sliding sleeve 32 is as wide as the protective plate 31 , and the length of the sliding sleeve 32 is less than that of the protective plate 31 , thereby providing a sufficient supporting surface and facilitating subsequent assembly with the air conditioning unit.

[0047] In one embodiment,

[0048] The ear plate 11 is provided with an opening slot for passing a bolt, which serves to connect and fix the external device.

[0049] In one embodiment,

[0050] Reinforcing ribs are added to the outer side wall of the slide 12 in the width direction, and two groups of reinforcing ribs are arranged on one side of the outer side wall in the width direction. The reinforcing ribs can significantly improve the local stiffness and strength of the slide 12, so that it can better withstand external loads, reduce deformation, disperse stress, and improve the structural stability of the entire shock absorber, especially when it is subjected to large loads or impacts.

[0051] In one embodiment,

[0052] The spring seat 13 is configured as two concentric semicircular structures, and the spring body 21 is placed in the inner diameter thereof. The spring body 21 is configured as a cylindrical spring.

[0053] The concentric circle design provides good symmetry, which helps the spring body 21 remain stable during compression and extension and reduces the influence of eccentric force. The cylindrical spring body 21 is easy to install and disassemble, and is convenient for maintenance and replacement.

[0054] In one embodiment,

[0055] The assembly clearance between the above-mentioned sleeve 32 and one side of the slide seat 12 is set to 0.5-0.8mm; appropriate assembly clearance can reduce the friction between the sleeve 32 and the slide seat 12, thereby reducing wear, improving the service life and operating efficiency of the shock absorber, and at the same time having a good anti-side force effect between the two.

[0056] In summary:

[0057] During the use of the unit of the utility model, the unit generates a certain vibration, and the vibration reduction part 2 expands and contracts to absorb and release the vibration impact, and the vibration reduction effect is obvious; when the unit generates a certain lateral force, it is bound to have a certain impact on the vibration reduction part 2. The mutually nested support part 1 and the protective part 3 effectively solve the impact of the lateral force on the vibration reduction device, and the anti-lateral force effect is significant.

[0058] The utility model is a composite shock absorber with high performance, low noise, and easy observation and maintenance.
