Technical Field
[0001] The utility model relates to the field of nut loosening prevention, and more specifically, it relates to a nut anti - detachment structure for an emergency lamp. Background Art
[0002] An emergency lamp is a lighting device, mainly to ensure that in the event of an emergency or critical situation, it provides necessary lighting and indication, thereby protecting people's lives and property. Common emergency lamps include a housing, a light source is arranged inside the housing, and a bolt - nut is detachably connected to the housing. The bolt - nut connection is a common mechanical connection method, usually used to connect two or more connecting parts. It consists of a bolt with a thread and a nut with a matching thread. The bolt and the nut are connected through the thread to form a tight connection, which can be used to fix and support various mechanical structures. However, in actual applications, due to the long - term vibration generated by the mechanical structure during operation, the bolt - nut connection often faces the problem of loosening, resulting in the nut becoming detached.
[0003] Therefore, a new solution is needed to solve this problem. Summary of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a nut anti - detachment structure for an emergency lamp.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A nut anti - detachment structure for an emergency lamp, including a housing, an installation seat is arranged on the housing, a groove is opened on the installation seat, a nut is detachably connected in the groove, a bolt for cooperating with the nut is detachably connected to the housing, the diameter of the groove opening is greater than the width of the nut, the diameter of the groove bottom is equal to the width of the nut, and several convex ribs for restricting the nut from detaching from the groove are arranged on the inner wall of the groove.
[0006] The utility model is further arranged as follows: A through - hole communicating with the groove and allowing the bolt to pass through is opened on the installation seat, a socket communicating with the through - hole is opened downward on the side of the installation seat facing away from the groove, and a limiting ring for tightly pressing against the socket is arranged on the bolt.
[0007] The utility model is further arranged as follows: The limiting ring is fixedly connected to the bolt and the limiting ring has elasticity.
[0008] The utility model is further arranged as follows: The limiting ring is made of rubber material.
[0009] The utility model is further arranged as follows: A guiding surface is opened on the inner wall of the socket.
[0010] The present utility model is further configured such that: there are two convex ribs, the two convex ribs are symmetrically arranged on the inner wall of the groove, and the distance between the convex ribs is less than the width of the nut.
[0011] The present utility model is further configured such that: the minimum distance from the convex rib to the bottom of the groove is equal to the thickness of the nut.
[0012] The present utility model is further configured such that: the distance from the convex rib to the mouth of the groove is less than the distance from the convex rib to the bottom of the groove.
[0013] In summary, the present utility model has the following beneficial effects: through the groove design on the mounting base, the nut can be stably placed in the groove. At the same time, the diameter of the bottom of the groove is equal to the width of the nut, ensuring that the nut is not easily shaken when subjected to an external force. Since the mouth of the groove is larger than the width of the nut, it makes it more efficient to install the nut into the groove, facilitating the insertion and removal of the nut. The convex ribs provided on the inner wall of the groove can effectively prevent the nut from falling out of the groove, greatly improving the connection stability, thereby avoiding the phenomenon of the nut coming off. Further, the design of the groove and the setting of the convex ribs both endow this nut anti - detachment structure of an emergency lamp with high structural strength and stability. Even when subjected to a large external force or vibration, the nut can remain in the groove, not easily loosening or falling off, thus ensuring the firmness of the overall connection.

[0020] The present utility model will be described in detail below with reference to the drawings and embodiments.
[0021] Embodiment:
[0022] A nut anti-loosening structure for an emergency lamp, as Figure 1 , Figure 2 and Figure 3 shown, includes a housing 1 made of plastic material. An installation seat 2 is provided on the housing 1, and a groove 3 is formed on the installation seat 2. A nut 4 is detachably connected in the groove 3, and a bolt 5 for cooperating with the nut 4 is detachably connected to the housing 1. Since both the bolt 5 and the nut 4 are detachably connected, it is convenient for people to repair and replace, thus reducing the maintenance cost of the equipment. The groove 3 can provide a protection space for the nut 4, so that the nut 4 is not easily damaged. And the cross-section of the groove 3 is hexagonal, which can just match the hexagonal nut 4, thus improving the stability of the nut 4 and making it not easy to shake during use.
[0023] As Figure 4 and Figure 5 shown, the diameter of the groove opening of the groove 3 is greater than the width of the nut 4, the diameter of the groove bottom of the groove 3 is equal to the width of the nut 4, and several convex ribs 6 for restricting the nut 4 from detaching from the groove 3 are provided on the inner wall of the groove 3. Specifically, two convex ribs 6 are provided, and the two convex ribs 6 are symmetrically arranged on the inner wall of the groove 3 and the distance between the convex ribs 6 is less than the width of the nut 4. Through the design of the groove 3 on the installation seat 2, the nut 4 can be stably placed in the groove 3. At the same time, the diameter of the groove bottom of the groove 3 is equal to the width of the nut 4, ensuring that the nut 4 is not easy to shake when subjected to external force. Since the groove opening of the groove 3 is larger than the width of the nut 4, it makes it more efficient to install the nut 4 into the groove 3, facilitating the insertion and removal of the nut 4. The convex ribs 6 provided on the inner wall of the groove 3 can effectively restrict the nut 4 from falling off the groove 3, greatly improving the connection stability, thus avoiding the phenomenon of the nut 4 detaching. Further, the design of the groove 3 and the setting of the convex ribs 6 both make this anti-loosening structure have high structural strength and stability. Even when subjected to large external force or vibration, the nut 4 can remain in the groove 3 and is not easy to loosen or fall off, thus ensuring the firmness of the overall connection. Since the two convex ribs 6 are symmetrically distributed on the inner wall of the groove 3, a double-locking mechanism is formed. When the nut 4 is placed in the groove 3, these two convex ribs 6 will respectively clamp the nut 4 from both sides, effectively preventing the movement of the nut 4. This double-locking not only increases the anti-loosening reliability but also improves the stability of the whole structure. Since the distance between the convex ribs 6 is less than the width of the nut 4, the nut 4 cannot freely rotate in the groove 3. This design can effectively prevent the nut 4 from loosening or rotating when subjected to external force or vibration, thus ensuring the tightness and durability of the connection.
[0024] Further, as Figure 4 and Figure 5As shown, the minimum distance from the convex rib 6 to the bottom of the groove 3 is equal to the thickness of the nut 4, and the distance from the convex rib 6 to the notch of the groove 3 is less than the distance from the convex rib 6 to the bottom of the groove 3. Since the minimum distance from the convex rib 6 to the bottom of the groove 3 is equal to the thickness of the nut 4, when the nut 4 is placed in the groove 3, its bottom will closely adhere to the bottom of the groove 3, and the convex rib 6 will exactly clamp the nut 4 from both sides, thus ensuring the precise position of the nut 4 in the groove 3 and avoiding loose or unstable connections caused by position deviation. Since the distance from the convex rib 6 to the notch of the groove 3 is less than the distance from the convex rib 6 to the bottom of the groove 3, when people place the nut 4 at the notch of the groove 3, the convex rib 6 will press against one side of the nut 4, and part of the nut 4 will still protrude outside the groove 3, which facilitates people to apply force to press the nut 4 into the groove 3 for fixation. Subsequently, people can screw the bolt 5 into the nut 4 to complete the installation operation.
[0025] As Figure 3 , Figure 4 and Figure 5 shown, a through hole 7 that communicates with the groove 3 and can accommodate the bolt 5 to pass through is provided on the mounting seat 2. A recess 8 that communicates with the through hole 7 is provided downward on the side of the mounting seat 2 facing away from the groove 3. A limiting ring 9 for pressing against the recess 8 is provided on the bolt 5. The design of the through hole 7 allows the bolt 5 to pass through the mounting seat 2 and cooperate with the nut 4 for connection. By tightening the bolt 5, the nut 4 can be firmly fixed in the groove 3, thereby improving the connection stability. The combined use of the recess 8 and the limiting ring 9 further enhances the connection strength between the bolt 5 and the mounting seat 2, preventing the bolt 5 from loosening or falling off, and thus improving the overall connection stability. Further, the limiting ring 9 is fixedly connected to the bolt 5 and the limiting ring 9 has elasticity. Specifically, the limiting ring 9 is made of rubber material. A guiding surface 10 is provided on the inner wall of the recess 8. Since the limiting ring 9 is fixedly connected to the bolt 5, it will not shift or fall off during use, thus ensuring a stable fit with the recess 8. Since the limiting ring 9 has elasticity, it can adapt to size changes within a certain range. Even if there are slight differences in the size of the recess 8, the limiting ring 9 can adapt to these differences through its elastic deformation to ensure a tight fit with the recess 8. The rubber material has good elasticity and buffering performance, which enables the limiting ring 9 to undergo elastic deformation when subjected to external forces, thereby absorbing and dispersing the impact force, protecting the structural integrity of the bolt 5 and the mounting seat 2, and extending the service life. The guiding surface 10 provided on the inner wall of the recess 8 can provide guidance and positioning for the installation of the bolt 5, ensuring the correct fit between the limiting ring 9 and the recess 8, which helps to improve the installation accuracy and reduce the risk of connection failure caused by improper installation.

All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
