Description

Technical Field

[0001] The utility model belongs to the field of plate connector production, in particular to a plate connector clamper for refrigeration equipment. Background Art

[0002] Connectors of various structures are commonly used in refrigeration equipment. Connectors are mostly formed by cutting, bending and processing plates to form plate connectors. The plate connectors have high installation strength and stability.

[0003] A clamp is required in the processing of sheet metal connectors. One end of the sheet metal is fixed by the clamp, and then the corresponding bending operation is performed. Most of the existing commonly used clamps for sheet metal processing include a screw and two pressure blocks. The two pressure blocks are arranged opposite to each other. The screw is rotatably connected to one of the pressure blocks. The screw thread is installed on the support block. The screw rotates to push the pressure block to move, and the sheet metal connector is clamped by the two pressure blocks. In the clamp, a bearing rotation connection structure is generally provided between the screw and the clamp block, resulting in higher process requirements. On the other hand, the clamping force of the clamp block is fixed, and sometimes the extension force is too large during the sheet metal bending process, causing the connector to loosen from the clamp, which is not conducive to production operations. Utility Model Content

[0004] In view of this, the utility model aims to provide a plate connector clamp for refrigeration equipment to simplify the structure, improve the stability of the clamp in clamping and fixing the plate connector, and improve production safety.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A plate connector clamp for refrigeration equipment, comprising a fixed block, wherein a wedge-shaped groove is provided in the vertical direction and a slide groove is provided in the horizontal direction, wherein the wedge-shaped groove is located above and connected to the slide groove, wherein the width of the upper end of the wedge-shaped groove is greater than the width of the lower end, wherein one groove wall is an inclined groove wall, and the other three groove walls are all vertical groove walls;

[0007] A lifting block is provided in the slide groove for horizontal sliding, and a clamping block is matched in the wedge-shaped groove. One side surface of the clamping block is an inclined surface that is in contact with the inclined groove wall of the wedge-shaped groove, and the remaining three side surfaces are vertical surfaces, wherein the vertical side surface that is away from the inclined side surface is a clamping side surface of the clamping block, and the bottom end of the clamping block extends out of the wedge-shaped groove and abuts against the top surface of the lifting block, and the bottom surface of the clamping block and the top surface of the lifting block are matching inclined surface structures.

[0008] Furthermore, the angle between the oblique side surface and the bottom surface of the clamping block is an acute angle.

[0009] Furthermore, the angle between the inclined side surface and the bottom surface of the clamping block is 40° to 50°, and the inclined angle of the inclined groove wall is 60° to 70°.

[0010] Furthermore, the clamping side surface of the clamping block is provided with anti-slip grooves.

[0011] Furthermore, a screw rod is provided on the small end surface of the lifting block, and the screw rod extends out of the fixing block and is matched with a nut.

[0012] Furthermore, a push rod is provided on the large end surface of the lifting block, and the push rod extends out of the fixed block. A spring is provided at a position of the push rod located inside the fixed block.

[0013] Furthermore, a dovetail groove is provided at the bottom of the slide groove, and a sliding protrusion matching the dovetail groove is protruded from the bottom surface of the lifting block, and the sliding protrusion and the dovetail groove form a sliding auxiliary structure.

[0014] Compared with the prior art, the plate connector holder for refrigeration equipment described in the utility model has the following advantages:

[0015] (1) The utility model has a simple structure. The lifting block lifts the clamping block and rises along the inclined groove wall of the wedge-shaped groove. The clamping block can press and fix the plate connector to be bent on the vertical groove wall of the wedge-shaped groove, thereby realizing convenient bending operation.

[0016] (2) In the present invention, the angle between the oblique side surface of the clamp block and its bottom surface is an acute angle, so that the clamp block and the oblique groove wall of the wedge-shaped groove are always in contact with each other, which is convenient for placing the plate connecting part between the clamp block and the vertical side wall, and facilitating the clamping operation of the plate connecting part.

[0017] (3) In the utility model, a screw-nut locking structure is provided on the small end face of the lifting block to fix the position of the lifting block. A push rod is provided on the large end face of the lifting block, and a spring is mounted on the push rod. When the plate connector is bent, the greater the extension force, the clamping block is driven upward, and the spring pushes the lifting block to move and continue to lift the clamping block, so that the greater the extension force of the plate connector, the greater the clamping force it receives, which effectively prevents the plate connector from falling off and ensures the bending safety.

The wedge-shaped groove 11 is located above the slide groove 12. The cross section of the wedge-shaped groove 11 is square, and the width of the upper end is greater than the width of the lower end. The upper end of the wedge-shaped groove 11 extends out of the top surface of the fixed block 1, and the lower end of the wedge-shaped groove is connected to the slide groove 12. Three of the four groove walls constituting the wedge-shaped groove 11 are vertical groove walls, and the other is an inclined groove wall 112. The inclined groove wall 112 has an inclination angle of 60° to 70°. At this time, a wedge-shaped structure is formed between the inclined groove wall 112 and the vertical groove wall 111 directly opposite to it.

[0030] The lifting block 5 is installed in the slide groove 12 in a horizontal sliding direction. In order to improve the sliding linearity of the lifting block 5, a dovetail groove 13 is opened at the bottom of the slide groove 12. A sliding protrusion matching the dovetail groove 13 is protruded from the bottom surface of the lifting block 5. The sliding protrusion and the dovetail groove form a sliding auxiliary structure. The clamping block 2 is installed in the wedge-shaped groove 11 in a sliding manner, and one side of the clamping block 2 is an inclined surface structure matching the inclined groove wall 112. The inclined surface is in contact with the inclined groove wall 112 of the wedge-shaped groove 11. The other three sides of the clamping block 2 are vertical surface structures, wherein the vertical side facing away from the inclined side of the clamping block is the clamping side of the clamping block 2. The clamping side is directly opposite to a vertical groove wall 111 of the wedge-shaped groove, and a clamping space 14 is formed between the clamping side and the vertical groove wall 111 for the bent sheet connector to be installed.
