[0032] To make the objectives, technical solutions, and advantages of this utility model more apparent, exemplary embodiments according to this utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, and not all embodiments of this utility model. It should be understood that this utility model is not limited to the exemplary embodiments described herein.

[0033] Example 1:

[0034] See Figures 1 to 3 This utility model provides a signal amplifier, including a signal amplifier body 1 and a fixing structure 2, a slot 5, and a connection port 4 disposed on the signal amplifier body 1. The fixing structure 2 is movably disposed on the signal amplifier body 1. The slot 5 can hold an IoT card, and the connection port 4 connects to an external cable. The external cable refers to a cable connected to the outside of the signal amplifier body 1, that is, a cable that is not part of the signal amplifier's own structure but is accessed from the outside or used in conjunction with the amplifier.

[0035] Furthermore, the fixing structure 2, the slot 5, and the wiring port 4 are all located on the side wall of the amplifier body 1.

[0036] As a preferred technical solution, the fixed structure 2 is movably disposed on the wall surface at the bottom of the signal amplifier body 1.

[0037] Furthermore, the fixing structure 2 includes a fixing frame 212, a spring 206, a guide groove 207, a guide rod 208, a guide plate 209, and a clamping plate 210. The fixing frame 212 has a wiring groove 202, a guide groove 207, and a placement hole 205. The spring 206 is installed in the placement hole 205, with one end of the spring 206 fixed to the bottom of the placement hole 205 and the other end fixed to the guide plate 209. The clamping plate 210 is installed on the side wall of the guide plate 209. The guide rod 208 is slidably disposed in the guide groove 207, and one end of the guide rod 208 is fixed to the side wall of the guide plate 209.

[0038] When the guide plate 209 contacts the side wall of the fixing frame 212, the clamping plate 210 and the cable tray 202 mate to form a fixing cavity for clamping the external cable. At this time, the spring 206 is in its natural state, and the clamping plate 210 cooperates with the cable tray 202 to fix the external cable.

[0039] In use, pulling the guide plate 209 causes the guide rod 208 to slide within the guide groove 207 under the influence of the guide plate 209. The spring 206 is stretched, causing the clamping plate 210 to separate from the cable tray 202, allowing the external cable to pass through the cable tray 202 and connect to the connector 4. After releasing the guide plate 209, the guide plate 209 contacts the side wall of the fixing frame 212 under the action of the spring 206, and the clamping plate 210 and the cable tray 202 align to form a fixing cavity for clamping the external cable.

[0040] In summary, according to the technical solution provided by the embodiments of this utility model, by setting a fixing structure on the amplifier body, the external cable is fixed in the fixing cavity formed by the cable tray and the clamp during use, which can prevent the interface between the cable interface and the signal amplifier end face from loosening when the external cable is pulled by external force, thereby improving the stability of the signal amplifier operation.

[0041] The aforementioned signal amplifier can be a wireless base station stabilized signal amplifier, etc., and this utility model does not limit it.

[0042] Furthermore, the guide groove 207 and the placement hole 205 are provided on the side wall of the fixed frame 212 opposite to the guide plate 209, and the spring 206 and the clamping plate 210 are provided on the side wall of the guide plate 209 opposite to the fixed frame.

[0043] As a preferred technical solution, multiple sets of guide grooves 207 are provided, symmetrically arranged on the side wall of the fixed frame 212 opposite to the guide plate 209. The number of guide rods 208 corresponds one-to-one with the number of guide grooves 207. Multiple sets of guide grooves 207 and guide rods 208 can make the guide plate 209 more stable during movement.

[0044] As a preferred technical solution, a pair of springs 206 and placement holes 205 are provided, and the pair of placement holes 205 are symmetrically arranged on the side wall opposite to the guide plate 209 of the fixing frame 212. The pair of springs 206 are respectively provided in the placement holes 205 and are symmetrically arranged, which can make the guide plate 209 move stably.

[0045] Furthermore, a rubber layer 203 is provided inside the cable tray 202. The rubber layer 203 can buffer the external cable when fixing it, preventing the external cable from being damaged when the clamp 210 and the guide groove 207 clamp it.

[0046] Furthermore, the fixing structure 2 also includes a slider 201. The signal amplifier body 1 has a groove 6 that matches the slider 201. The slider 201 can slide within the groove 6, allowing the fixing structure to move on the signal amplifier. When it is necessary to fix an external cable, the fixing structure 2 can be pulled outward relative to the signal amplifier body 1 by using the slider 201 in conjunction with the groove 6. When it is not necessary to fix an external cable, the fixing structure 2 can be stored at the bottom of the signal amplifier body 1, saving space.

[0047] As a preferred technical solution, a pair of sliders 201 are provided, and correspondingly, a pair of sliding grooves 6 are provided. The pair of sliders 201 and the pair of sliding grooves 6 are adapted to each other, so that the fixing bracket 212 can move on the side wall of the signal amplifier body 1. When it is necessary to fix the external cable, it can be moved out to save space.

[0048] Furthermore, the guide plate 209 has a pull block 211 on the side wall away from the clamping plate 210, and the side wall of the clamping plate 210 near the cable tray 202 is arc-shaped. The pull block 211 makes it easy to pull the guide plate 209. The arc-shaped clamping plate 210 is compatible with external cables and can better fix external cables.

[0049] Furthermore, the fixing structure 2 also includes a heat dissipation hole 204, which is opened on the fixing frame 212 and communicates with the cable tray 202. It is used to provide a heat dissipation channel for the external cables in the cable tray 202, so as to avoid the accumulation of heat generated by the external cables during power-on and signal transmission, which would affect the safety and stability of the equipment or cables.

[0050] Example 2:

[0051] See Figure 1 and Figure 4 Based on Embodiment 1, this embodiment provides a signal amplifier, including a support structure 3.

[0052] Furthermore, the support structure 3 includes a placement frame 308, a fixing rod 303, a connecting plate 305, and a backing plate 307. The connecting plate 305 is installed at the bottom of the signal amplifier body 1, the fixing rod 303 is installed at the bottom of the signal amplifier body 1 via the connecting plate 305, the upper end of the placement frame 308 is movably sleeved on the fixing rod 303, and the lower end is equipped with the backing plate 307.

[0053] Preferably, a plurality of support structures are provided and disposed at the bottom of the signal amplifier body 1 to support the signal amplifier body.

[0054] As a preferred technical solution, there are four support structures 3, which are symmetrically arranged at the bottom of the signal amplifier body.

[0055] Preferably, the support structure 3 further includes a limiting pin 302 disposed on the placement frame 308, a plurality of limiting holes 304 are provided on the fixing rod 303, and a locking hole 301 matching the limiting hole 304 is provided on the placement frame 308.

[0056] In use, the placement rack 308 can move on the fixed rod 303. The limiting pin 302 can pass through the card hole 301 and the limiting hole 304 to fix the placement rack 308 on the fixed rod 303, thereby facilitating the adjustment of the height of the signal amplifier body 1. The abutment 307 contacts the placement plane to keep the signal amplifier body 1 stable when it is working.

[0057] Furthermore, multiple limiting holes 304 are provided, and the size of the limiting pin 302 is adapted to the size of the limiting hole 304 and the card hole 301. Multiple limiting holes 304 are equally spaced on the side wall of the fixing rod 303, and the matching limiting pin 302 can make the fixed placement frame 308 more stable.

[0058] Furthermore, the placement rack 308 is provided with multiple sets of reinforcing ribs 306, and the bottom of the support plate 307 is provided with anti-slip texture. The multiple sets of reinforcing ribs 306 are evenly distributed on the placement rack 308 to increase the strength of the placement rack 308, and the anti-slip texture increases the friction between the support plate 307 and the placement surface, which can reduce the probability of the support plate 307 sliding when supporting.

[0059] Working principle: The movable fixed frame 212 allows a pair of sliders 201 to slide within a pair of grooves 6 on the signal amplifier body 1. An IoT card is inserted into the card slot 5. Pulling the pull block 211 causes the guide plate 209 to slide through several guide rods 208 within several guide grooves 207. At this time, a pair of springs 206 are stretched. The external cable passes through the wiring groove 202 and connects to the wiring port 4. One side of the external cable abuts against the rubber layer 203 of the wiring groove 202. Releasing the pull block 211 resets the pair of springs 206, causing the guide plate 209 to move. This accelerates the movement of the guide plate. 209 moves towards the cable tray 202 to contact the external cable, thereby fixing the external cable in the cable tray 202 to prevent it from coming off. When placing the signal amplifier body 1, the limiting pin 302 is removed, and the placement bracket 308 moves a certain distance on the fixing rod 303 so that the locking hole 301 corresponds to one of the several limiting holes 304. The limiting pin 302 is inserted, and the limiting pin 302 passes through the locking hole 301 and one of the several limiting holes 304, so that the placement bracket 308 can be fixed on the fixing rod 303, thereby facilitating the adjustment of the height of the signal amplifier body 1 and facilitating heat dissipation.

[0060] See above. Figures 1 to 4 The signal amplifier provided by this utility model is described in detail, and the signal amplifier has the following characteristics:

[0061] First, it features a unique fixing structure. The method of fixing the external cable by having a rubber layer in the cable tray abut against the side wall of the external cable, combined with a spring-reset mechanism that moves the guide plate to contact the external cable, is innovative. This effectively prevents the external cable from coming loose due to external forces, a fundamental difference from traditional signal amplifiers that rely solely on interface connections. This fixing method ensures a stable connection of the external cable during use, greatly reducing signal transmission interruptions caused by loose cables and ensuring stable operation of the signal amplifier. Existing technologies often fall short in ensuring stability and cannot achieve this effect.

[0062] Second, it has a unique support structure. By setting a support structure at the bottom of the signal amplifier body 1, and using the combination of the placement bracket 308, fixing rod 303, limiting pin 302, limiting hole 304 and card hole 301, the height of the signal amplifier body can be adjusted, which facilitates heat dissipation.
