DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 4 As shown, this embodiment provides a transformer clamp for clamping a transformer 1, and the transformer clamp includes a substrate 2, a clamping member 3, a locking member 4, and an elastic member 5. The substrate 2 is used to carry the transformer 1; the clamping member 3 is rotatably connected to the substrate 2, and the clamping member 3 is used to rotate relative to the substrate 2 to clamp or release the transformer 1; one end of the locking member 4 passes through the clamping member 3 and is screwed to the substrate 2; the elastic member 5 is sleeved outside the locking member 4, and the two ends of the elastic member 5 are respectively against the clamping member 3 and the locking member 4, and the elastic member 5 is used to apply elastic force to the clamping member 3 to clamp the transformer 1.

[0029] The transformer clamp includes a base plate 2 for supporting the transformer 1 upward, a plurality of clamping members 3 arranged at intervals for pressing the transformer 1 downward, and a locking member 4 which penetrates the clamping member 3 vertically and is connected with the base plate 2 by thread and is used to drive the clamping member 3 close to the base plate 2 to clamp the transformer 1; the clamping member 3 includes a connecting portion 31, and a plurality of supporting portions 32 protruding toward the adjacent clamping members 3; after the threaded portion 41 of the locking member 4 penetrates the connecting portion 31, the limiting portion 42 of the locking member 4 forms a vertical extrusion with it, and the supporting portion 32 is pressed on the top surface of the transformer 1. The locking member 4 vertically penetrates the clamping member 3 and is connected with the base plate 2 by thread. When the locking member 4 is screwed out upward, its limiting portion 42 moves upward, so that the clamping member 3 has a movable space for moving upward. At this time, the operator can move the clamping member 3 upward according to the height of the transformer 1 on the base plate 2, so that the bottom surface of the supporting portion 32 is flush with or slightly higher than the top surface of the transformer 1. Because the clamping member 3 and the base plate 2 are connected only by the locking member 4, the clamping member 3 can move the supporting portion 32 to the top of the transformer 1 by rotating around the locking member 4. When the locking member 4 is screwed downward, its limiting portion 42 moves downward and pushes the clamping member 3 to move downward, so that the supporting portion 32 exerts downward pressure on the top surface of the transformer 1, thereby fixing it. Conversely, the transformer 1 can be released by simply screwing the locking member 4 upward and moving the supporting portion 32 out from the top of the transformer 1 by rotating. It can be seen that the fixing clamp disclosed in the present application only clamps the top and bottom surfaces of the transformer 1 and will not cause damage to the side walls of the transformer 1. In addition, when using the fixing clamp, the transformer 1 can be locked and released by simply twisting the locking member 4 and rotating the clamping member 3. The operation is very simple and easy to use.

[0030] In this embodiment, the clamping member 3 includes a connecting portion 31 and a clamping portion 32 connected to each other, wherein the connecting portion 31 is rotatably connected to the substrate 2, and the clamping portion 32 protrudes from the connecting portion 31 in a direction perpendicular to the rotation axis of the connecting portion 31. The connecting portion 31 can drive the clamping portion 32 to rotate relative to the substrate 2, and the clamping portion 32 is used to clamp the transformer 1. There are two clamping portions 32, and the two clamping portions 32 are arranged on opposite sides of the connecting portion 31 in a direction perpendicular to the rotation axis of the connecting portion 31.

[0031] The substrate 2 is in the shape of a strip, and the clamping members 3 are distributed along a straight line at intervals along the length direction of the substrate 2. Correspondingly, a screw hole 21 for adapting to the locking member 4 is formed on the substrate 2. The clamping member 3 is in the shape of a "T", and the two supporting parts 32 are distributed on the opposite sides of the connecting part 31. The transformer 1 is placed on the substrate 2 and is located between two adjacent clamping members 3. Each transformer 1 is clamped simultaneously by the clamping members 3 on both sides thereof. Since a protruding structure may be provided at the bottom of the transformer 1, in order to avoid damage caused by extrusion, the substrate 2 is formed with a receiving groove 22 and a receiving hole 23 between two adjacent clamping members 3 for adapting to the protruding structure at the bottom of the transformer 1.

[0032] In this embodiment, the number of the clamping members 3 is six, and the clamping portions 32 of each two adjacent clamping members 3 are used to clamp the transformer 1 together. Since the clamping members 3 are provided with two opposite clamping portions 32, that is, each clamping member 3 can lock two transformers 1 at the same time, the transformer clamp is more compact in structure and can reduce the number of operations (taking the fixing of five transformers 1 as an example, twelve clamping tools need to be fixed on the transformer 1 respectively in the prior art, while only six clamping members 3 need to be operated by the fixing clamp of the present application), thereby improving work efficiency. It is understandable that in some other embodiments, the number of clamping members 3 can be set according to actual needs, such as five, seven, etc., which are not limited here.

[0033] In this embodiment, along the rotation axis direction of the clamping member 3 , the clamping member 3 is provided with a connecting hole 311 , the base plate 2 is provided with a screw hole 21 , and one end of the locking member 4 passes through the connecting hole 311 and is screwed to the screw hole 21 .

[0034] The connecting hole 311 includes a first hole section 312 and a second hole section 313, the second hole section 313 is connected to the first hole section 312 and the screw hole 21 respectively, the inner diameter of the second hole section 313 is smaller than the inner diameter of the first hole section 312, and a step surface 314 is provided between the second hole section 313 and the first hole section 312;

[0035] The elastic member 5 is at least partially received in the first hole section 312 , and one end of the elastic member 5 facing the substrate 2 abuts against the step surface 314 .

[0036] The locking member 4 has a threaded portion 41 and a limiting portion 42 at both ends thereof. The threaded portion 41 is connected to the base plate 2 , and one end of the elastic member 5 that is away from the base plate 2 abuts against the limiting portion 42 .

[0037] The connecting portion 31 is vertically formed with a connecting hole 311 for the locking member 4 to pass through; the connecting hole 311 includes a first hole section 312 and a second hole section 313 located below the first hole section 312; the inner diameter of the first hole section 312 is greater than or equal to the outer diameter of the limiting portion 42 of the locking member 4, and the inner diameter of the second hole section 313 is greater than or equal to the outer diameter of the threaded portion 41 of the locking member 4 and smaller than the outer diameter of the limiting portion 42 of the locking member 4. The fixing fixture also includes an elastic member 5, which is sleeved on the threaded portion 41 of the locking member 4, one end of which abuts against the limiting portion 42 of the locking member 4, and the other end of which abuts against the step surface 314 formed at the junction of the first hole section 312 and the second hole section 313. When the locking member 4 is screwed downward, its limiting portion 42 presses the elastic member 5 downward, and transmits the pressure downward to the clamping member 3 through the elastic member 5, thereby generating downward pressure on the transformer 1. By providing the elastic member 5 , a certain movable space is provided between the clamping member 3 and the transformer 1 (the elastic member 5 is squeezed to deform), so the probability of the clamping member 3 squeezing and damaging the transformer 1 can be reduced to a certain extent.

[0038] In this embodiment, the substrate 2 is provided with a receiving groove 22, which is provided on one side of the clamping member 3 along a direction perpendicular to the rotation axis of the clamping member 3, and the receiving groove 22 is used to receive the transformer 1. There is one receiving groove 22 between each two adjacent clamping members 3, that is, the number of the receiving grooves 22 is one less than the number of the clamping members 3.

[0039] The substrate 2 is further provided with a receiving hole 23, which is provided at one side of the receiving groove 22, and is used to receive components of the transformer 1. It is understandable that, in some other embodiments, the position of the receiving hole 23 can also be set according to the actual shape of the transformer, such as being set to communicate with the receiving groove 22, or being set to overlap with the receiving groove 22, which is not limited here.

[0040] By providing the receiving groove 22 and the receiving hole 23 on the substrate 2, interference with the protruding part of the transformer 1 can be avoided and positioning can be achieved.

Any technician familiar with the art can use the above disclosed technical content to make many possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
