Abstract
Description
Technical Field
[0001] This utility model relates to the field of security technology, specifically to a SIM card cover fixing device for a control ball. Background Technology
[0002] With the widespread adoption of intelligent surveillance equipment, PTZ cameras, as a common outdoor security device, are widely used in various monitoring systems. PTZ cameras typically need to operate for extended periods in harsh outdoor environments; therefore, their design must consider multiple requirements, including waterproofing, dustproofing, and resistance to high and low temperatures. Furthermore, to ensure normal operation, PTZ cameras require regular replacement of storage media such as SIM cards and TF cards. Since these cards are crucial to the normal functioning of the device, designing a card cover that is both easy to operate and effectively protects the card slots has become a challenge in PTZ camera design.
[0003] Currently, several design solutions for SIM card cover on the market have several problems: To ensure the security of the SIM card cover, it usually needs to be locked with screws. However, some SIM card cover products place the screws externally, requiring them to be tightened onto the SIM card cover during use. While this design provides some security, the screws are easily lost when removing or replacing the card, causing significant inconvenience. Some SIM card cover systems prevent screw loss by attaching chains to the screws. Although this design avoids screw loss, the addition of chains and other extra components increases production costs and may affect the product's aesthetics and ease of use. Other SIM card cover systems use plastic materials and rely on screws that cannot be easily loosened and forceful compression to enhance the cover's anti-detachment capability. This design is not only prone to damage during actual operation but also still carries the risk of the cover falling off under extreme conditions, failing to effectively guarantee security. To ensure the device's waterproof performance, SIM card cover systems typically incorporate sealing rings at the joint of the SIM card cover. However, most existing sealing rings are flat designs, requiring excessive pressure to fully adhere and achieve a waterproof effect. This not only increases the difficulty of operation but may also cause the sealing ring to gradually fail during long-term use, thus affecting the waterproof effect. Utility Model Content
[0004] The purpose of this invention is to provide a SIM card cover fixing device for a control ball, thereby solving the problems existing in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a SIM card cover fixing device for a control ball, comprising:

[0016] As can be seen from the above technical solution, this utility model has the following beneficial effects:
[0017] The SIM card cover fixing device of this control ball effectively prevents the problem of screw loss in traditional designs by using a combination of a non-detachable screw and the SIM card cover, avoiding inconvenience caused by screw loss during operation. At the same time, the non-detachable screw design increases the connection stability between the screw and the SIM card cover, ensuring the efficiency and safety of the device in daily use. Compared to the traditional design that requires an additional chain, this invention simplifies the structure through the reasonable layout of the screw fixing device and connecting chain, avoiding unnecessary additional components and thus effectively reducing production costs. Furthermore, the product has a compact structure, improving its overall aesthetics and reliability. The sealing ring of this invention adopts a structure with elasticity and a concave-convex design, where the protrusion on the upper part and the recess on the lower part of the sealing ring can better form a tight contact with the SIM card cover and the middle shell during installation, thereby ensuring a stronger waterproof effect. Compared to existing flat sealing rings, this design achieves a superior sealing effect without requiring excessive pressure, reducing the risk of seal damage caused by excessive pressure. The design of fixing the SIM card plate to the middle shell improves the stability of the card slot, effectively avoiding the problem of card slot loosening or damage caused by frequent card removal and replacement, and extending the service life of the control ball. The design of this invention ensures that the SIM card cover is easy and safe to install and remove, avoiding the trouble caused by lost screws or insecure fixing in traditional designs, while improving the convenience of equipment maintenance and reducing maintenance time and costs.

The SIM card cover 3 is secured by a non-removable screw, preventing it from loosening due to vibration or other factors during prolonged use. Simultaneously, the sealing ring effectively prevents moisture and dust from entering, protecting the internal circuitry and enhancing the device's waterproof and dustproof performance. The overall structure is simple and easy to assemble, improving the device's reliability and durability.
[0026] In practical implementation, the middle shell 1 can be made of high-strength plastic or metal to provide sufficient strength and stability. The SIM card plate 5 can be fixed inside the middle shell by clips or screws to ensure a secure connection. The sealing ring 6 is made of rubber or other elastic and corrosion-resistant materials, and the upper protrusion 61 and the lower recess 62 ensure a sealing effect. The design of the non-removable screw 2 can adopt a self-locking thread or an anti-loosening structure to prevent the screw from loosening. The SIM card cover 3 can be made of different materials such as plastic or metal according to usage requirements to adapt to different environments and usage conditions.
[0027] The SIM card plate 5 is fixed inside the middle shell 1. In this embodiment, the SIM card plate 5 is fixed inside the middle shell 1 by means of screws or card slots. Stable fixing of the SIM card plate effectively prevents displacement or loosening of the SIM card due to external forces during use, thereby ensuring stable electrical connection of the SIM card and reducing operational malfunctions. This embodiment allows the SIM card plate 5 to be more firmly fixed inside the middle shell 1, avoiding loosening or displacement of the SIM card plate due to external forces such as vibration and impact. This fixing method enhances the overall stability and durability of the device, improves the electrical performance of the SIM card, and reduces the occurrence of malfunctions.
[0028] In this embodiment, the SIM card plate 5 can be fixed by a pre-set slot or screw hole inside the middle shell 1. The slot can be designed to accommodate SIM cards of different sizes and shapes to ensure secure installation. The screw hole can mate with the positioning hole inside the middle shell, using screws to firmly fix the SIM card plate 5, enhancing stability.
[0029] The sealing ring 6 is fitted inside the middle shell 1. After being inserted into the middle shell 1, the sealing ring 6 makes tight contact with the inner surface of the middle shell, forming a sealing structure when the SIM card cover 3 is installed, preventing external contaminants such as moisture and dust from entering the device. The elasticity and concave-convex design of the sealing ring ensures a good seal, maintaining high sealing performance even during prolonged use. The installation of the sealing ring 6 effectively isolates the device from external environmental damage, extending its lifespan, especially in harsh environments, preventing damage or malfunction caused by moisture or dust infiltration. This design enhances the device's waterproof and dustproof capabilities, improving its stability and reliability. The sealing ring 6 can be made of rubber, silicone, or other elastic materials, and its surface can be designed as circular, rectangular, or self-adaptive shapes to better fit the inner surface of the middle shell 1. The sealing ring may have internal reinforcing ribs or structures to enhance the sealing effect and ensure its elasticity and durability during long-term use.
[0030] The SIM card cover 3 is secured to the middle shell 1 by a captive screw 2. This captive screw design prevents the screw from loosening due to vibration or external force, ensuring the SIM card cover remains firmly installed. This design guarantees the long-term stability of the SIM card cover and prevents it from easily falling off. The captive screw 2 effectively prevents screw loosening, especially during long-term operation and in vibrating environments, avoiding the risk of the SIM card cover falling off due to loose screws. This design improves the reliability and long-term durability of the device, making it particularly suitable for environments requiring high safety and stability.
[0031] The lock-on screw can be a self-locking thread or a specially designed lock-on screw, such as one with a lock washer or locking mechanism. The screw can be made of corrosion-resistant alloy or stainless steel to ensure long-term stability and durability in various environments.
[0032] A washer 4 is attached to the captive screw 2, and the washer 4 has a notch. In this embodiment, the captive screw 2 is fitted with a washer 4, and the washer 4 has a notch. The notch design allows the washer to fit more tightly between the screw and the SIM card cover 3 during installation, enhancing its fixing effect. The notch helps the washer distribute force evenly when under stress, thereby avoiding damage caused by the screw being too tight or too loose. Through this design, the captive screw 2 can more firmly fix the SIM card cover 3, avoiding loosening caused by vibration and other factors during long-term use. This embodiment can provide a more stable fixing effect through the cooperation of the washer 4 and the captive screw 2. The notch design on the washer 4 allows the washer to provide even support when under stress, avoiding excessive or uneven pressure at a single point. At the same time, the notch design also facilitates the installation and removal of the washer, making it convenient for operation during maintenance or replacement. Overall, the washer 4 effectively enhances the anti-loosening function of the captive screw 2 and improves the reliability of the device in high-vibration environments.
[0033] In practical implementation, gasket 4 can be made of rubber, silicone, metal, or other materials with a certain degree of elasticity and durability to adapt to the usage requirements in different environments. The shape and position of the notch can be adjusted according to the screw design and usage requirements to ensure that the gasket can function correctly. The thickness and material selection of gasket 4 need to be reasonably optimized based on factors such as the vibration environment and temperature changes of the equipment.
[0034] The sealing ring 6 has a protrusion 61 on its upper surface and a recess 62 on its lower surface. In this embodiment, the sealing ring 6 has a protrusion 61 on its upper surface and a recess 62 on its lower surface. When the sealing ring 6 is installed inside the middle shell 1, the protrusion 61 can fit tightly against the inner surface of the middle shell, while the recess 62 forms a mating fit with the corresponding surface of the middle shell. In this way, the sealing ring can form an effective sealing structure when under pressure, preventing external moisture, dust, etc. from entering the equipment. The design of the protrusion 61 and the recess 62 ensures that the sealing ring can provide a more uniform and stable sealing effect when the device is under stress, thereby improving the waterproof and dustproof capabilities. By providing the protrusion 61 and the recess 62 on the sealing ring 6, the present invention can effectively enhance the sealing performance. The protrusion 61 provides a tighter contact surface to prevent moisture and dust from entering; the recess 62 helps the sealing ring to form a better sealing effect when under external pressure, enhancing the waterproof and dustproof function. This design makes the sealing ring more stable and reliable, and can continuously and effectively protect the internal components of the equipment in different environments. It is especially suitable for equipment such as control balls that are exposed to the external environment for a long time.
[0035] In practical implementation, the sealing ring 6 can be made of materials with excellent elasticity and anti-aging properties, such as rubber, silicone, and polyurethane, to ensure a good sealing effect. The shape, size, and position of the protrusion 61 and the recess 62 can be optimized according to the specific equipment design to better fit the middle shell 1 and other structural components. The material of the sealing ring 6 should be selected according to the equipment's operating environment, such as temperature, humidity, and chemical exposure, to ensure good sealing performance under various operating conditions.
[0036] Working process: First, the middle shell 1 serves as the basic support structure for the entire device, providing a fixed position and support. The SIM card plate 5 is installed into the middle shell 1 using screws or slots, ensuring the SIM card's stable position. Next, the sealing ring 6 is installed at the corresponding position on the middle shell 1, with the protrusion 61 and the recess 62 engaging to form an effective seal, preventing external moisture and dust from entering. Subsequently, the SIM card cover 3 covers the SIM card plate 5 and is secured by a captive screw 2 passing through it. The washer 4 on the captive screw 2 enhances the stability of the screw's fixation through its notch design, ensuring that the SIM card cover will not loosen due to vibration or external force. After completing the above steps, the entire device possesses stable fixation and good sealing performance, allowing the SIM card to operate stably, while also providing strong waterproof and dustproof capabilities.
