Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a filter anti-loosening and anti-detachment structure. Background Technology

[0002] In modern electronic devices, filters are key components whose performance directly affects the stability and reliability of the entire system. With the rapid development of electronic technology, filters are increasingly used in various complex environments, which places higher demands on their structural stability and long-term performance.

[0003] In practical applications, filters often face numerous challenges. On one hand, vibrations generated during equipment operation cause continuous mechanical stress on the filter's internal structure. Prolonged exposure to vibration can easily affect the epoxy resin encapsulation within the filter. On the other hand, prolonged use can gradually reduce the adhesion of the epoxy resin, leading to loosening or even detachment between the epoxy resin and the outer shell. If this occurs, the filter's electrical performance will be severely compromised, potentially even causing the entire device to malfunction. Utility Model Content

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

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a filter anti-loosening and detachment structure, including a housing and a reinforcing mechanism for preventing epoxy resin from falling off;

[0006] The reinforcing mechanism consists of anchoring components placed inside the housing and heat-treated components placed outside the housing, wherein the anchoring components are in two sets, which are symmetrically distributed on the inner side of the housing.

[0007] Preferably, the anchoring component is mainly composed of several longitudinally distributed anchoring plates. Each anchoring plate includes a contact plate and a reinforcing plate. One side of the contact plate is attached to the inner wall of the housing, and the reinforcing plate is vertically fixed to the other side of the contact plate.

[0008] Preferably, a connecting groove is vertically formed 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 at the bottom of the housing, the end of the locking screw passes through several reinforcing plates in sequence, and the end of the locking screw is threadedly connected to a locking nut that abuts against the uppermost locking screw.

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

[0011] Preferably, the spiral coil is fitted with an insulating sleeve that is fixedly connected to the outer wall of the housing. The output pipe and the delivery pipe both penetrate the inner wall of the insulating sleeve, and the inner wall of the insulating sleeve is also bonded with heat-insulating paper.

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

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] (1) By setting the anchor plate, epoxy resin is filled into the inner cavity of the shell. The reinforcing plate in the anchor plate is immersed in the epoxy resin. After the epoxy resin is cured, the reinforcing plate and the epoxy resin are tightly bonded to form a mechanical anchor, which greatly enhances the overall strength of the epoxy resin potting and prevents it from falling off.

[0015] (2) By using connecting blocks and connecting grooves, simply aligning the connecting blocks and sliding them into the connecting grooves allows several anchor plates to be arranged longitudinally along the grooves. This facilitates quick manual adjustment of the number and height of the anchor plates according to the depth of the epoxy resin to be potted, preventing the epoxy resin from failing to form an effective anchoring support structure after curing due to improper anchor plate placement. Proper adjustment of the anchor plates ensures that the epoxy resin can tightly bond with the anchor plates at different potting depths, evenly distributing stress and preventing cracking or detachment of the epoxy resin from the shell due to localized stress concentration. Simultaneously, accurately matching the number and height of the anchor plates effectively improves potting efficiency, avoids material waste, and reduces production costs.

[0016] (3) By setting up the insulation sleeve and the heat insulation paper, the insulation sleeve can effectively form a heat insulation barrier outside the spiral coil, reducing the influence of the external environment on the temperature of the medium flowing inside the spiral coil. The heat insulation paper is usually made of multi-layer composite material, including a reflective layer, a heat insulation layer and a base layer. It reduces heat transfer by reflecting and absorbing heat, and has good heat insulation performance, so as to prevent the heat emitted by the spiral coil from being transferred to the insulation sleeve and accidentally scalding the operator.

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figure 1-3 As shown, a filter anti-loosening and detachment structure includes a housing 1 and a reinforcing mechanism for preventing epoxy resin from falling off.

[0024] The reinforcing mechanism consists of an anchoring component placed inside the housing 1 and a heat-treated component placed outside the housing 1;

[0025] The anchoring components consist of two sets, which are symmetrically distributed inside the shell 1.

[0026] The anchoring component is mainly composed of several longitudinally distributed anchoring plates. The anchoring plates include contact plates 2 and reinforcing plates 3. One side of the contact plate 2 is attached to the inner wall of the shell 1, and the reinforcing plate 3 is vertically fixed to the other side of the contact plate 2.

[0027] By setting the anchor plate, epoxy resin is filled into the inner cavity of the shell 1. The reinforcing plate 3 in the anchor plate is immersed in the epoxy resin. After the epoxy resin is cured, the reinforcing plate 3 and the epoxy resin are tightly bonded to form a mechanical anchor, which greatly enhances the overall strength of the epoxy resin potting and prevents it from falling off.

[0028] Furthermore, referring to Figure 3 As shown, it is worth noting that a connecting groove is vertically provided on the inner wall of the housing 1, and a connecting block that is fixed to the contact plate 2 slides in the connecting groove.

[0029] By using connecting blocks and connecting grooves, simply aligning the connecting blocks and sliding them into the connecting grooves allows several anchor plates to be arranged longitudinally along the grooves. This facilitates quick manual adjustment of the number and height of the anchor plates according to the depth of the epoxy resin to be potted, preventing improper anchor plate placement that could result in the epoxy resin failing to form an effective anchoring support structure after curing. Proper adjustment of the anchor plates ensures a tight bond between the epoxy resin and the anchor plates at different potting depths, evenly distributing stress and preventing cracking or detachment of the epoxy resin from the shell due to localized stress concentration. Simultaneously, accurately matching the number and height of the anchor plates effectively improves potting efficiency, avoids material waste, and reduces production costs.

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

[0031] With the locking screw 4 and locking nut 5 in place, once the connecting block is aligned and slid into the connecting groove, the reinforcing plate 3 in the anchor plate can slide simultaneously to the body of the locking screw 4. After the anchor plates are arranged longitudinally, the locking nut 5 only needs to be screwed into the end of the locking screw 4 so that it abuts against the uppermost reinforcing plate 3. In this way, the locking screw 4 and the locking nut 5 can effectively bind several longitudinally arranged anchor plates together, ensuring their stability during epoxy resin potting.

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

[0033] By setting up heat treatment components, a hot water pipe is connected to the output pipe 8 before potting the epoxy resin, so that the hot water medium is continuously fed into the spiral coil 6 and discharged out through the delivery pipe 7. In this way, the viscosity of the epoxy resin is reduced by preheating the shell 1, so that it can flow better and fill into various parts of the shell. At the same time, it can also reduce the curing shrinkage stress caused by temperature difference, improve the bonding quality between the epoxy resin and the shell, and enhance the anti-detachment property.

[0034] Furthermore, referring to Figure 1 and Figure 2 As shown, it is worth noting that the spiral coil 6 is fitted with an insulation sleeve 9 that is fixedly connected to the outer wall of the shell 1. The output pipe 8 and the delivery pipe 7 both penetrate the inner wall of the insulation sleeve 9. Furthermore, the inner wall of the insulation sleeve 9 is also bonded with heat insulation paper 10, which is made of multi-layer composite material, including a reflective layer, a heat insulation layer, and a base layer.

[0035] By setting up the insulation sleeve 9 and the heat insulation paper 10, the insulation sleeve 9 can effectively form an insulation barrier outside the spiral coil 6, reducing the influence of the external environment on the temperature of the medium flowing inside the spiral coil 6.

[0036] Furthermore, the heat insulation paper 10 is usually made of multi-layer composite materials, including a reflective layer, a heat insulation layer, and a base layer. It reduces heat transfer by reflecting and absorbing heat, and has good heat insulation performance, so as to prevent the heat emitted by the spiral coil 6 from being transferred to the heat insulation sleeve 9 and accidentally scalding the operator.
