[0002] A motor protector is a device used to protect motors. It monitors abnormal conditions such as the motor's current, temperature, overload, and short circuit, and automatically cuts off the power supply when a fault occurs, thereby preventing the motor from being overloaded or damaged. It is a key safeguard in motor control systems and is widely used in various motor equipment.

[0003] At present, most motor protectors on the market are installed in distribution boxes by bolts. However, for distribution boxes with compact internal space, using bolts to install motor protectors may take up too much space, resulting in the inability to arrange other electrical components reasonably or making installation difficult. In addition, industrial sites are usually filled with dust, moisture and various chemicals. These environmental factors pose a potential threat to the electronic components and connection lines of the motor protector, which may cause their performance to degrade or malfunction. Therefore, maintenance personnel need to regularly disassemble, clean and inspect the motor protector. However, the traditional bolt installation method often requires the use of more tools, which increases the complexity of installation and disassembly.

[0004] Therefore, in order to solve the above problems, a side-mounted motor protector is proposed. Utility Model Content

[0006] To achieve the above object, the utility model provides the following technical solution: a side-mounted motor protector comprises a protector and a telescopic assembly, a support plate is mounted on one side of the outer wall of the protector, and the telescopic assembly is mounted on a side surface of the mounting plate away from the protector;

[0007] Among them, the telescopic assembly includes a receiving tube, which is installed horizontally along the support plate and rotatably connected to the support plate. The first screw and the second screw are respectively threadedly connected in the receiving tube, and a fixing plate is installed on the side of the first screw and the second screw that are away from each other.

[0008] Furthermore, two mounting plates are installed at intervals along the horizontal direction of the support plate on the side surface of the support plate away from the protector, and the two mounting plates are both installed with first bearings passing through the support plate along the horizontal direction; the outer wall of the receiving tube is connected to the inner walls of the inner rings of the two first bearings, and the receiving tube is rotatably connected to the support plate through the first bearing and the mounting plate.

[0010] Further, the thread directions of the first internally threaded tube and the second internally threaded tube are opposite, and the thread directions of the first screw rod and the second screw rod are opposite.

[0011] Furthermore, both mounting plates are provided with positioning holes extending transversely through the support plate and located below the first bearing, and bidirectional telescopic rods are clamped in the two positioning holes, and the extending ends on both sides of the bidirectional telescopic rods are respectively connected to the opposite surfaces of the two fixing plates.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 In this embodiment, a side-mounted motor protector utilizes a telescopic assembly 3 mounted on a support plate 2. By rotating a receiving tube 33, a first screw rod 36 and a second screw rod 37 can perform opposite telescopic movements in the receiving tube 33, thereby adjusting the distance between the two fixing plates 39. Thus, the protector 1 can be flexibly installed on the relative plate surfaces in different distribution boxes, and at the same time, it is also convenient to disassemble the protector 1.

[0023] Specifically, a side-mounted motor protector 1 in this embodiment includes a protector 1 and a telescopic assembly 3, a support plate 2 is mounted on one side of the outer wall of the protector 1, and the telescopic assembly 3 is mounted on a side surface of the mounting plate 31 away from the protector 1;

[0024] Among them, the telescopic assembly 3 includes a receiving tube 33, which is installed horizontally along the support plate 2 and is rotatably connected to the support plate 2. The first screw 36 and the second screw 37 are respectively threadedly connected in the receiving tube 33, and a fixing plate 39 is installed on the side of the first screw 36 and the second screw 37 that are away from each other.

[0025] In actual use, the user drives the first screw 36 and the second screw 37 to move in opposite directions by rotating the receiving tube 33 clockwise and counterclockwise, so that the first screw 36 and the second screw 37 can be close to and away from each other in the receiving tube 33. Therefore, the distance between the two fixing plates 39 can be adjusted, so that the protector 1 can be flexibly installed on the relative plate surfaces in different distribution boxes.

[0026] Two mounting plates 31 are installed at a horizontal interval along the upper edge of the support plate 2 on one side of the support plate 2 away from the protector 1, and the two mounting plates 31 are both installed with first bearings 32 passing through the support plate 2 laterally; the outer wall of the receiving tube 33 is connected to the inner walls of the inner rings of the two first bearings 32, and the receiving tube 33 is rotatably connected to the support plate 2 through the first bearing 32 and the mounting plate 31.

[0027] The first internally threaded tube 34 and the second internally threaded tube 35 are respectively clamped on the inner walls on both sides of the receiving tube 33 . The first internally threaded tube 34 is threadedly connected to the first screw rod 36 , and the second screw rod 37 is threadedly connected to the second internally threaded tube 35 .

[0028] The thread directions of the first internally threaded tube 34 and the second internally threaded tube 35 are opposite, and the thread directions of the first screw rod 36 and the second screw rod 37 are opposite.

[0029] In actual use, by rotating the receiving tube 33, the first screw 36 and the second screw 37 can be rotated in the first internal threaded tube 34 and the second internal threaded tube 35 respectively. Since the thread directions of the first internal threaded tube 34 and the second internal threaded tube 35 are opposite, rotating the receiving tube 33 can make the first screw 36 and the second screw 37 move in opposite directions.

[0030] Both mounting plates 31 are provided with positioning holes 4 extending transversely through the support plate 2 and located below the first bearing 32 . Two-way telescopic rods 41 are clamped in the two positioning holes 4 . The two side extension ends of the two-way telescopic rods 41 are respectively connected to the opposite surfaces of the two fixing plates 39 .

[0031] The restriction of the bidirectional extension rod can prevent the first thread and the second screw rod 37 from sliding out of the first internally threaded tube 34 and the second internally threaded tube 35 respectively when the receiving tube 33 rotates.

[0032] Bearing seats 38 are installed on the opposite surfaces of the two fixed plates 39. The outer walls of the first thread and the second screw 37 at one end away from each other are respectively connected to the inner walls of the inner rings of the bearings inside the two bearing seats 38. The first screw 36 and the second thread are rotatably connected to the two fixed plates 39 through the bearing seats 38.

[0033] The side surfaces of the two fixing plates 39 that are away from each other are both provided with anti-skid pads 5 .

[0034] The protective pad can increase the friction between the fixing plate 39 and the inner wall of the distribution box, so that the protector 1 can be installed more firmly.

[0035] A warning light 6 and an alarm 7 are installed at intervals on the upper end of the protector 1 .

[0036] In actual use, when the protector 1 detects that the current, voltage, etc. of the motor are faulty, the warning light 6 and the alarm 7 can emit obvious sound and light signals to remind the staff to pay attention and take timely measures to check or repair.

[0037] The working principle of the above embodiment is:

[0038] In the first step, when the user needs to install the protector 1 in the distribution box, by rotating the receiving tube 33, the first screw 36 and the second screw 37 respectively engaged in the first internal threaded tube 34 and the second internal threaded tube 35 move away from each other. With the cooperation of the two-way telescopic rod 41, the two fixing plates 39 can be driven to extend to the two ends of the receiving tube 33 respectively, so that the spacing between the two fixing plates 39 can be adjusted according to the size of the relative panels inside the different distribution boxes, and the protector 1 is clamped between the two relative panels in the distribution box, so that the protector 1 can be flexibly used in distribution boxes of different sizes and distribution boxes of different environments.

[0039] In the second step, when the maintenance personnel need to disassemble the protector 1, by rotating the receiving tube 33 in the opposite direction, the first screw 36 and the second screw 37 are driven to retract along the two ends of the receiving tube 33 to the inside of the receiving tube 33, so that the two fixing plates 39 are close to each other, thereby the protector 1 can be taken out of the distribution box. Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents.
