Description

Technical Field

[0001] The present invention relates to the technical field of filters, and specifically relates to a filter anti-loosening and anti-dropping structure. Background Art

[0002] In modern electronic devices, filters, as key components, directly affect the stability and reliability of the entire system. With the rapid development of electronic technology, filters are increasingly widely used in various complex environments, which poses higher requirements for their structural stability and long-term performance.

[0003] During the actual use of filters, many challenges are often faced. On the one hand, the vibrations generated during the operation of the device will cause continuous mechanical stress impacts on the internal structure of the filter. In a long-term vibration environment, the epoxy resin potting part inside the filter is easily affected. On the other hand, long-term use will gradually reduce the adhesion of the epoxy resin, resulting in loosening or even dropping between the epoxy resin and the housing. Once this situation occurs, the electrical performance of the filter will be severely disturbed, and even the entire device may malfunction. Summary of the Invention

[0004] To solve the above technical problems, a filter anti-loosening and anti-dropping structure is provided, which solves the problems in the above background art.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: a filter anti-loosening and anti-dropping structure, including a housing, and further including a strengthening mechanism for preventing the epoxy resin from dropping off;

[0006] The strengthening mechanism is composed of an anchoring component placed inside the housing and a heat treatment component placed outside the housing, wherein there are two groups of the anchoring components, and the two groups are symmetrically distributed on the inner side of the housing.

[0007] Preferably, the anchoring component is mainly composed of a plurality of longitudinally distributed anchoring plates, the anchoring plate includes a contact plate and a strengthening plate, one side of the contact plate fits the inner wall of the housing, and the strengthening plate is vertically fixed on the other side of the contact plate.

[0008] Preferably, a connecting groove is vertically opened on the inner wall of the housing, and a connecting block fixed to the contact plate slides in the connecting groove.

[0009] Preferably, a locking screw is vertically fixed on the inner wall of the bottom end of the housing, the end of the locking screw sequentially penetrates through a plurality of the strengthening plates, and a locking nut that abuts against the uppermost locking screw is threadedly connected to the end of the locking screw.

[0010] Preferably, the heat treatment component includes a spiral coil pipe sleeved on the outer wall of the shell, the water inlet end of the spiral coil pipe is fixedly communicated with an output pipe, and the water outlet end of the spiral coil pipe is fixedly communicated with a conveying pipe.

[0011] Preferably, a heat preservation sleeve fixedly connected with the outer wall of the shell is sleeved outside the spiral coil pipe, the output pipe and the conveying pipe both penetrate through the inner wall of the heat preservation sleeve, and a heat insulation paper is also glued on the inner wall of the heat preservation sleeve.

[0012] Preferably, the heat insulation paper is made of a multi-layer composite material.

[0013] Compared with the prior art, the advantages of the present invention are as follows:

[0014] (1) Through the arrangement of the anchoring plate, epoxy resin is filled into the inner cavity of the shell, and the reinforcing plate in the anchoring plate is immersed in the epoxy resin. Then, after the epoxy resin is cured, the reinforcing plate and the epoxy resin are tightly combined to form mechanical anchoring, greatly enhancing the overall strength of the epoxy resin potting and preventing it from falling off.

[0015] (2) Through the arrangement of the connecting block and the connecting groove, only by aligning the connecting block and sliding it into the connecting groove, several anchoring plates can be longitudinally arranged along the connecting groove. Then, it is convenient for workers to quickly adjust the arrangement quantity and height of the anchoring plates according to the depth of the epoxy resin to be potted, so as to avoid the situation that due to the unreasonable arrangement of the anchoring plates, an effective anchoring support structure cannot be formed after the epoxy resin is cured. Reasonably adjusting the anchoring plates can ensure that the epoxy resin can be tightly combined with the anchoring plates at different potting depths, evenly disperse stress, and avoid cracking of the epoxy resin or detachment from the outer shell caused by local stress concentration. At the same time, accurately matching the quantity and height of the anchoring plates can effectively improve the potting efficiency, avoid material waste, and reduce production costs.

[0016] (3) Through the arrangement of the heat preservation sleeve and the heat insulation paper, the heat preservation sleeve can effectively establish a heat preservation barrier outside the spiral coil pipe, reducing the temperature influence of the external environment on the flowing medium in the spiral coil pipe. And the heat insulation paper is usually made of a multi-layer composite material, which includes a reflection layer, a heat insulation layer, a base layer, etc. It reduces heat transfer by reflecting and absorbing heat, and has good heat insulation performance, so as to avoid the heat dissipated by the spiral coil pipe being transferred to the heat preservation sleeve and scalding the operators by mistake.

[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and other obvious variations can be conceived by those skilled in the art.

[0023] Referring to Figures 1-3 As shown, a filter anti-loosening and anti-dropping structure includes a housing 1, and further includes a strengthening mechanism for preventing epoxy resin from falling off;

[0024] The strengthening mechanism is composed of an anchoring component placed inside the housing 1 and a heat treatment component placed outside the housing 1;

[0025] Among them, there are two groups of anchoring components, which are symmetrically distributed on the inner side of the housing 1;

[0026] The anchoring component is mainly composed of a number of longitudinally distributed anchoring plates. The anchoring plate includes a contact plate 2 and a reinforcing plate 3. One side of the contact plate 2 is attached to the inner wall of the housing 1, and the reinforcing plate 3 is vertically fixed on the other side of the contact plate 2;

[0027] Through the arrangement of the anchoring plates, epoxy resin is filled into the inner cavity of the housing 1. The reinforcing plate 3 in the anchoring plate is immersed in the epoxy resin. Then, after the epoxy resin cures, the reinforcing plate 3 is tightly combined with the epoxy resin to form a mechanical anchor, greatly enhancing the overall strength of the epoxy resin potting and preventing it from falling off.

[0028] Furthermore, referring to Figure 3 As shown, it should be noted that a connection groove is vertically opened on the inner wall of the housing 1, and a connection block fixed to the contact plate 2 slides in the connection groove;

[0029] Through the arrangement of the connection block and the connection groove, only by aligning and sliding the connection block into the connection groove, several anchoring plates can be longitudinally arranged along the connection groove. Then, it is convenient for manual adjustment of the arrangement quantity and height of the anchoring plates according to the depth of the epoxy resin to be potted, so as to avoid the situation that due to unreasonable arrangement of the anchoring plates, an effective anchoring support structure cannot be formed after the epoxy resin cures. Reasonably adjusting the anchoring plates can ensure that the epoxy resin can be tightly combined with the anchoring plates at different potting depths, evenly disperse the stress, and avoid cracking of the epoxy resin or detachment from the outer shell due to local stress concentration. At the same time, accurately matching the quantity and height of the anchoring plates can effectively improve the potting efficiency, avoid material waste, and reduce production costs.

[0030] Furthermore, referring toFigure 3 As shown, it is worth noting that a locking screw rod 4 is vertically fixed on the inner wall at the bottom end of the housing 1. The end of the locking screw rod 4 sequentially penetrates through a plurality of reinforcing plates 3, and a locking nut 5 that abuts against the uppermost locking screw rod 4 is threadedly connected to the end of the locking screw rod 4;

[0031] Through the arrangement of the locking screw rod 4 and the locking nut 5, when the connecting block is aligned and slid into the connecting groove, the reinforcing plate 3 in the anchoring plate can synchronously slide to the rod body of the locking screw rod 4. Then, after the longitudinal arrangement of the anchoring plates is completed, only need to screw the locking nut 5 onto the end of the locking screw rod 4 so that it abuts against the uppermost reinforcing plate 3. In this way, the locking screw rod 4 cooperates with the locking nut 5 to effectively limit a plurality of longitudinally arranged anchoring plates together, ensuring their stability during the epoxy resin potting.

[0032] In addition, referring to Figure 1 and Figure 2 As shown, it is worth noting that the heat treatment component includes a spiral coil pipe 6 sleeved on the outer wall of the housing 1. The water inlet end of the spiral coil pipe 6 is fixedly communicated with an output pipe 8, and the water outlet end of the spiral coil pipe 6 is fixedly communicated with a conveying pipe 7;

[0033] Through the arrangement of the heat treatment component, before potting the epoxy resin, the output pipe 8 is externally connected to a hot water pipe, so that the hot water medium continuously flows into the spiral coil pipe 6 and is discharged outward through the conveying pipe 7. In this way, by preheating the housing 1, the viscosity of the epoxy resin is reduced, making it flow and fill into each part of the housing better. At the same time, it can also reduce the curing shrinkage stress caused by temperature differences, improve the bonding quality between the epoxy resin and the housing, and enhance the anti-detachment property.

[0034] Furthermore, referring to Figure 1 and Figure 2 As shown, it is worth noting that a heat preservation sleeve 9 fixedly connected to the outer wall of the housing 1 is sleeved outside the spiral coil pipe 6. Both the output pipe 8 and the conveying pipe 7 penetrate through the inner wall of the heat preservation sleeve 9, and a heat insulation paper 10 is also glued on the inner wall of the heat preservation sleeve 9. The heat insulation paper 10 is made of multiple composite materials, including a reflective layer, a heat insulation layer, a base layer, etc.;

[0035] Through the arrangement of the heat preservation sleeve 9 and the heat insulation paper 10, the heat preservation sleeve 9 can effectively establish a heat preservation barrier outside the spiral coil pipe 6, reducing the temperature influence of the external environment on the flowing medium in the spiral coil pipe 6;

[0036] And the heat insulation paper 10 is usually made of multiple composite materials, including a reflective layer, a heat insulation layer, a base layer, etc. It reduces heat transfer by reflecting and absorbing heat, and has good heat insulation performance to prevent the heat emitted by the spiral coil pipe 6 from being transferred to the heat preservation sleeve 9 and scalding the operator by mistake.

[0037] The foregoing has shown and described 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, and what is described in the above embodiments and the specification is only the principle of the present invention.
