Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliance applications, and particularly relates to an all-round shock-absorbing installation structure and method for a micro-compressor. Background Art

[0002] Most of the main units of common air-conditioning protective suits are worn on the back by a strap-type bracket. Due to the vibration generated by the compressor during the working process of this wearable main unit, because its contact points are in contact with the skin surface of the wearer, under the influence of resonance, the friction generated on the back of the patient is affected. Especially in summer, in order to maintain breathability, the wearer wears thinner clothes and trousers, and is in a long-term working state, the intensity of the generated friction will greatly affect the comfort. Therefore, we propose an all-round shock-absorbing installation structure and method for a micro-compressor. Summary of the Invention

[0003] The main purpose of the present invention is to provide an all-round shock-absorbing installation structure and method for a micro-compressor.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0005] An all-round shock-absorbing installation structure for a micro-compressor includes an external surrounding shell and a bottom shell of the compression mechanism. A shock-absorbing washer is screwed and fixed inside the external surrounding shell. An assembly gap maintaining component is provided between the shock-absorbing washer and the bottom shell of the compression mechanism for reducing the assembly gap and achieving buffering after assembly. Two housing limiting sleeves for restricting the lateral displacement of the bottom shell of the compression mechanism after embedding and installation are fixedly connected to the top wall of the external surrounding shell. The shock-absorbing washer includes an embedded sandwich washer and a filling and fitting pad. The embedded sandwich washer is screwed and fixed to the filling and fitting pad. The filling and fitting pad is embedded and clamped inside the external surrounding shell. The assembly gap maintaining component includes a clamping limiting piece, a connecting and clamping pad block, a bottom connecting locking bracket, and an assembly screw. The clamping limiting piece is arranged on the top of the connecting and clamping pad block. The top end of the assembly screw penetrates through the connecting and clamping pad block, and the top end of the assembly screw is threadedly connected to the clamping limiting piece. The bottom connecting locking bracket is fixedly connected to the bottom of the bottom shell of the compression mechanism. The connecting and clamping pad block is disposed between the clamping limiting piece and the bottom connecting locking bracket.

[0006] A further improvement of the present invention is that the external surrounding shell is provided with an assembly groove cavity for embedding and buffering the filling and fitting pad. The filling and fitting pad is snap-connected to the inside of the assembly groove cavity. An internal thread assembly groove is provided at the bottom side of the assembly groove cavity. The bottom end of the assembly screw is threadedly connected to the internal thread assembly groove.

[0007] A further improvement of the present invention is that the two casing limiting sleeves are symmetrically distributed, and an annularly distributed elastic fitting clip is fixedly connected to the inner side of the casing limiting sleeve. A bottom fitting arc pad fixedly connected to the top wall of the external surrounding casing is arranged inside the casing limiting sleeve. After the bottom shell of the compression mechanism is embedded inside the casing limiting sleeve through the compression mechanism, the elastic fitting clip wraps the outer wall of the bottom shell of the compression mechanism to reduce the joint gap. At the same time, the bottom of the bottom shell of the compression mechanism is buffered by the bottom fitting arc pad.

[0008] A further improvement of the present invention is that a buffer cotton layer is provided on the side wall of the connecting clip and fitting pad in contact with the bottom connecting and locking bracket.

[0009] A further improvement of the present invention is that Teflon coatings are sprayed on the contact surfaces of the embedded sandwich washer and the bottom connecting and locking bracket to reduce the contact friction between the embedded sandwich washer and the bottom connecting and locking bracket.

[0010] A further improvement of the present invention is an installation method of an all-round shock-absorbing installation structure for a micro-compressor, including:

[0011] S1. During assembly, first embed the shock-absorbing washer into the position of the external surrounding casing. Through the threaded action of the internal thread assembly groove and the assembly screw, the assembly support between the embedded sandwich washer and the external surrounding casing is completed. Until the filling and fitting pad is embedded inside the assembly groove cavity, the assembly of the shock-absorbing washer is completed.

[0012] S2. After the assembly of the shock-absorbing washer is completed, insert the bottom of the bottom shell of the compression mechanism into the inner side of the casing limiting sleeve, so that the assembly screw penetrates through the bottom connecting and locking bracket to complete the lateral displacement limitation of the bottom shell of the compression mechanism. Until the bottom of the bottom shell of the compression mechanism contacts the bottom fitting arc pad, the elastic fitting clip wraps around the outside of the bottom shell of the compression mechanism. At this time, the pre-locking of the position of the bottom shell of the compression mechanism is completed.

[0013] S3. After the assembly between the bottom of the bottom shell of the compression mechanism and the casing limiting sleeve is completed, sleeved the connecting clip and fitting pad on the top of the assembly screw. Then, sleeved the clamping limiting piece on the outside of the assembly screw and screwed it through the threaded action. Until the connecting clip and fitting pad are clamped by the bottom connecting and locking bracket under the threaded action of the clamping limiting piece through extrusion and positioning, the assembly is completed. Furthermore, when the bottom of the bottom shell of the compression mechanism vibrates, due to the bottom and the outside being wrapped by the elastic fitting clip and the bottom fitting arc pad, and at the same time, the upper and lower ends of the bottom connecting and locking bracket are resonantly buffered by the filling and fitting pad and the connecting clip and fitting pad, the shock absorption of the compressor carried inside the bottom shell of the compression mechanism is realized.

[0014] Compared with the prior art, after the compressor is assembled in the present invention, the connecting clip pastes the cushion block to extrude the beam position under the action of the thread of the clamping limiting piece, thereby realizing the clamping of the bottom connection locking bracket and the connecting clip pasting the cushion block, so that after the bottom shell of the compression mechanism is fixed, the connecting clip pasting the cushion block and the bottom connection locking bracket are clamped on the top of the embedded sandwich washer. When the work generates vibration, since the filling and fitting pad is embedded in the inner side of the assembly groove cavity, the shaking displacement generated after the shock-absorbing washer is assembled can be reduced, thereby reducing the displacement amplitude of the shock-absorbing washer. At the same time, after the connecting clip pastes the cushion block and is clamped between the bottom connection locking bracket and the clamping limiting piece, when the bottom connection locking bracket generates vibration along with the bottom shell of the compression mechanism, the elastic release of the connecting clip pasting the cushion block can also buffer the tilting swing. Moreover, after the bottom of the compression mechanism bottom shell is embedded in the inner side of the casing limiting sleeve, and the elastic fitting clip wraps around the outer side of the compression mechanism bottom shell, when the local contact vibration is enlarged due to the displacement and twisting of the body of the wearing person, it can buffer the local single-direction vibration of the compression mechanism bottom shell, thereby improving the shock-absorbing adaptation effect.

For those skilled in the art, it is understandable that some well-known structures and their descriptions in the attached drawings may be omitted. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] Embodiment

[0022] Please refer to Figures 1-4 , which includes an external surrounding cartridge case 1 and a compression mechanism bottom case 3. A shock-absorbing washer 2 is screwed and fixed inside the external surrounding cartridge case 1. An assembly gap maintaining component 4 for reducing the assembly gap and achieving buffering after assembly is provided between the shock-absorbing washer 2 and the compression mechanism bottom case 3. Two housing limiting sleeves 5 for restricting the lateral displacement of the compression mechanism bottom case 3 after being embedded and installed are fixedly connected to the top wall of the external surrounding cartridge case 1. The shock-absorbing washer 2 includes an embedded sandwich washer 21 and a filling and fitting pad 22. The embedded sandwich washer 21 is screwed and fixed to the filling and fitting pad 22. The filling and fitting pad 22 is embedded and engaged inside the external surrounding cartridge case 1. The assembly gap maintaining component 4 includes a clamping limiting piece 41, a connecting and pasting pad block 42, a bottom connecting and locking bracket 43, and an assembly screw 44. The clamping limiting piece 41 is arranged on the top of the connecting and pasting pad block 42. The top end of the assembly screw 44 penetrates through the connecting and pasting pad block 42, and the top end of the assembly screw 44 is threadedly connected to the clamping limiting piece 41. The bottom connecting and locking bracket 43 is fixedly connected to the bottom of the compression mechanism bottom case 3. The connecting and pasting pad block 42 is placed between the clamping limiting piece 41 and the bottom connecting and locking bracket 43.

[0023] In this embodiment, after the compressor and the bottom shell 3 of the compression mechanism are fixedly assembled by screws, first, the operator installs the shock-absorbing washer 2 by embedding it in the position of the external surrounding shell 1. Then, through the screwing and fixing of the internal thread assembly groove 12 and the assembly screw 44, the assembly support between the embedded sandwich washer 21 and the external surrounding shell 1 is completed. After the filling fitting pad 22 is embedded in the inner side of the assembly groove cavity 11, the fixation between the shock-absorbing washer 2 and the external surrounding shell 1 is completed. Then, the bottom of the compression mechanism bottom shell 3 is inserted into the inner side of the housing limiting sleeve 5, so that the assembly screw 44 penetrates through the bottom connection locking bracket 43 to complete the lateral displacement limitation of the compression mechanism bottom shell 3. Until the bottom of the compression mechanism bottom shell 3 contacts the bottom fitting arc pad 52, the elastic fitting clip 51 wraps around the outside of the compression mechanism bottom shell 3. At this time, the pre-locking of the position of the compression mechanism bottom shell 3 is completed. After the assembly between the bottom of the compression mechanism bottom shell 3 and the housing limiting sleeve 5 is completed, the connecting clip fitting pad 42 is sleeved on the top of the assembly screw 44. Then, the clamping limiting piece 41 is sleeved on the outside of the assembly screw 44 and screwed through the thread action. Until the connecting clip fitting pad 42 is squeezed and positioned under the thread action of the clamping limiting piece 41, after the clamping between the bottom connection locking bracket 43 and the connecting clip fitting pad 42 is realized, the compression mechanism bottom shell 3 is fixed, and the connecting clip fitting pad 42 and the bottom connection locking bracket 43 are clamped on the top of the embedded sandwich washer 21 by the clamping limiting piece 41. When it works and generates vibrations, since the filling fitting pad 22 is embedded in the inner side of the assembly groove cavity 11, the shaking displacement amount generated after the shock-absorbing washer 2 is assembled can be reduced, thereby reducing the displacement amplitude of the shock-absorbing washer 2. At the same time, after the connecting clip fitting pad 42 is clamped between the bottom connection locking bracket 43 and the clamping limiting piece 41, when the bottom connection locking bracket 43 vibrates with the compression mechanism bottom shell 3, the elastic release of the connecting clip fitting pad 42 can also buffer the tilting vibration. And after the bottom of the compression mechanism bottom shell 3 is embedded in the inner side of the housing limiting sleeve 5, since the elastic fitting clip 51 wraps around the outside of the compression mechanism bottom shell 3, when the local contact vibration is enlarged due to the displacement and twisting of the wearer's body, it can buffer the local single-direction vibration of the compression mechanism bottom shell 3, thereby improving the shock absorption adaptation effect.

[0024] Among them, the external surrounding jam 1 is provided with an assembly groove cavity 11 for filling and embedding the buffer of the fitting pad 22. The filling fitting pad 22 is snap-connected to the inner side of the assembly groove cavity 11. An internal thread assembly groove 12 is provided at the bottom side of the assembly groove cavity 11. The bottom end of the assembly screw member 44 is threadedly connected to the internal thread assembly groove 12. After the embedded sandwich washer 21 is fixed by screwing between the assembly screw member 44 arranged on the inner side and the internal thread assembly groove 12, the filling fitting pad 22 sinks to the inner side of the assembly groove cavity 11, increasing the friction force and reducing the displacement caused by vibration. At the same time, when the embedded sandwich washer 21 vibrates with the bottom shell 3 of the compression mechanism, it can also be buffered by the contact between the filling fitting pad 22 and the assembly groove cavity 11 under vibration, avoiding hard contact between the shock-absorbing washer 2 and the external surrounding jam 1 during vibration and causing the vibration amount to expand.

[0025] Among them, the two housing limiting sleeves 5 are symmetrically distributed. An annularly distributed elastic fitting clip 51 is fixedly connected to the inner side of the housing limiting sleeve 5. A bottom fitting arc pad 52 fixedly connected to the top wall of the external surrounding jam 1 is provided on the inner side of the housing limiting sleeve 5. After the bottom shell 3 of the compression mechanism is embedded in the inner side of the housing limiting sleeve 5, the elastic fitting clip 51 wraps the outer wall of the bottom shell 3 of the compression mechanism to reduce the joint gap. At the same time, the bottom fitting arc pad 52 buffers the bottom of the bottom shell 3 of the compression mechanism. After the bottom of the bottom shell 3 of the compression mechanism is embedded in the inner side of the housing limiting sleeve 5, it is laterally restricted by the housing limiting sleeve 5. Since the elastic fitting clip 51 wraps the outside of the bottom shell 3 of the compression mechanism, when the wearer displaces and twists the body, resulting in an increase in local contact vibration, the elastic fitting clip 51 plays a role in buffering the local single-direction vibration of the bottom shell 3 of the compression mechanism, thereby improving the shock-absorbing adaptation effect. At the same time, due to the support of the bottom fitting arc pad 52 at the bottom of the bottom shell 3 of the compression mechanism, the compressor plays an elastic release role when vibration occurs.

[0026] Among them, a buffer cotton layer is provided on one side wall of the connecting clip attaching block 42 in contact with the bottom connecting locking bracket 43. The bottom of the connecting clip attaching block 42 is provided with a buffer cotton layer to maintain the contact surface between the connecting clip attaching block 42 and the bottom connecting locking bracket 43 after the clamping limiting piece 41 is installed. When the longitudinal displacement occurs between the bottom connecting locking bracket 43 and the connecting clip attaching block 42 due to the vibration of the compressor, it can increase the contact friction force and reduce the displacement amount. At the same time, it can also buffer the contact surface between the connecting clip attaching block 42 and the bottom connecting locking bracket 43.

[0027] Among them, the contact surfaces of the embedded sandwich washer 21 and the bottom connection locking bracket 43 are all sprayed with a Teflon coating, which is used to reduce the contact friction between the embedded sandwich washer 21 and the bottom connection locking bracket 43; through the Teflon coating sprayed on the contact surfaces of the embedded sandwich washer 21 and the bottom connection locking bracket 43, it plays a role in reducing the friction generated during their contact, avoiding the phenomenon that excessive wear occurs between the embedded sandwich washer 21 and the bottom connection locking bracket 43 under the influence of compressor vibration, resulting in an increase in the assembly gap and further an increase in the vibration gap, and playing a protective role.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
