Technical Field
[0001] The utility model relates to the technical field of mechanical parts, in particular to a quick-installation T-shaped nut. Background Art
[0002] In mechanical manufacturing, it is often necessary to fix parts in a T-shaped groove on a vertical plane, and at this time, a T-shaped nut is needed for connection; the traditional assembly method of the T-shaped nut is to insert it through the side notch of the T-shaped groove and slide it along the T-shaped groove to the pre-set position.
[0003] However, in many cases, the pre-set position of the T-shaped nut does not meet the requirements and needs to be adjusted again. At this time, the T-shaped nut needs to be slid out of the T-shaped groove at the pre-set position and then slid into another T-shaped groove corresponding to the position to be adjusted. Often, under complex mechanical working conditions, there are workpieces blocking on the T-shaped groove. At this time, the workpiece needs to be lifted to adjust the T-shaped nut. And when the working environment is harsh, dirt is likely to accumulate in the T-shaped groove, resulting in difficulty for the T-shaped nut to slide therein; this causes the installation of the T-shaped nut to take a long time and the clamping efficiency to be low; and the commonly used T-shaped nut in the vertical T-shaped groove also has problems of being unable to fix the position and being easy to slide along the T-shaped groove. Summary of the Utility Model

Detailed Description of the Preferred Embodiments
[0025] To enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the present utility model with reference to the accompanying drawings. Other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] As Figure 1 、 Figure 4 、 Figure 5 and Figure 7 shown, the present utility model provides a quick-installation T-shaped nut, which includes a T-shaped block 1 for installation in a T-shaped groove 2. The T-shaped block 1 includes a clamping portion 101 that fits with the inner groove of the T-shaped groove 2 and a rotating shaft portion 102 that is rotatably arranged relative to the opening groove of the T-shaped groove 2. The lower end of the rotating shaft portion 102 is fixedly connected to the clamping portion 101, and the upper end extends out of the opening groove of the T-shaped groove 2 to form a connecting seat 103 with an internal thread groove 104. The long side dimension L3 of the clamping portion 101 is greater than the width L1 of the opening groove of the T-shaped groove 2, and the short side dimension L4 of the clamping portion 101 is not greater than the width L1 of the opening groove of the T-shaped groove 2. A top-tightening assembly that elastically tensions with the bottom of the inner groove of the T-shaped groove 2 is provided at the bottom of the clamping portion 101. Preferably, the rotating shaft portion 102 is cylindrical, the outer diameter of the rotating shaft portion 102 is the same as the short side dimension L4 of the clamping portion 101, and is smaller than the width L1 of the opening groove of the T-shaped groove 2. Due to the above structural design of the T-shaped block 1, when the long side of the T-shaped block 1 rotates to a position parallel to the T-shaped groove 2, the T-shaped block 1 enters and exits the T-shaped groove 2 from the positive notch of the T-shaped groove 2. Continuing to rotate the T-shaped block 1 that enters the T-shaped groove 2, and under the elastic action of the top-tightening assembly, the upper surface of the clamping portion 101 of the T-shaped block 1 is in close contact with the top surface of the inner groove of the T-shaped groove 2, so that the T-shaped block 1 is clamped and tightly fixed in the T-shaped groove 2, thereby preventing the T-shaped block 1 from sliding in the vertically arranged T-shaped groove 2. Further preferably, in order to facilitate the rotation of the clamping portion 101, the short side of the clamping portion 101 is an arc surface, and the arc surfaces of the two short sides are concentrically arranged. The diameter of the corresponding circle of the arc surface is the long side dimension L3 of the clamping portion 101, and this dimension is not greater than the inner groove width L2 of the T-shaped groove 2.
[0027] A rotation-stopping assembly 3 for restricting the rotation of the T-shaped block is further provided on the connecting seat 103 along the short side direction of the clamping portion 101. When the T-shaped block 1 is clamped with the T-shaped groove 2, the setting of the rotation-stopping assembly 3 can restrict the continuous rotation of the T-shaped block 1, completing the quick installation of the T-shaped nut at any position in the T-shaped groove 2, with high installation efficiency.
[0028] In one embodiment, as Figure 4 shown, there are two rotation-stopping assemblies 3, which are symmetrically distributed on both sides of the internal thread groove 104 of the connecting seat 103. Among them, as Figure 6 and Figure 8As shown, the anti-rotation assembly 3 includes an anti-rotation column 301 and a guide pin 302. A vertical sliding hole 105 is formed in the connecting seat 103. The anti-rotation column 301 is slidably arranged in the vertical sliding hole 105, and the lower end of the anti-rotation column 301 extends out of the connecting seat 103 and is inserted into the opening groove of the T-shaped groove 2. The guide pin 302 is sequentially arranged through the connecting seat 103 and the anti-rotation column 301, and a guide through groove 307 for the vertical movement of the guide pin 302 is provided on the anti-rotation column 301. The lower end of the anti-rotation column 301 passes through the vertical sliding hole 105 up and down to complete the limit switching of the anti-rotation of the T-shaped block 1. In order to stably install the guide pin 302 on the connecting seat 103, one end of the guide pin 302 has an external thread, and an internal thread is provided in any through hole of the connecting seat 103. Through the cooperation of the internal and external threads, the guide pin 302 is fixed in the connecting seat 103. Further preferably, the above anti-rotation column 301 is a column with a non-cylindrical cross-section, so that while the anti-rotation column 301 slides up and down along the vertical sliding hole 105, it can drive the connecting seat 103 to rotate at the same time.
[0029] As Figure 2 and Figure 9 shown, in order to further improve the replacement speed and reduce the space usage during the switching process, the anti-rotation assembly 3 includes a first spring 303 and a first set screw 304. An adjustment cavity 305 is formed in the anti-rotation column 301. The upper end of the adjustment cavity 305 is communicated with the guide through groove 307, and the lower end of the adjustment cavity 305 is communicated with the bottom of the anti-rotation column 301 through a first internal thread portion 306. The first spring 303 is located in the adjustment cavity 305, and the two ends of the first spring 303 are sequentially abutted against the first set screw 304 screwed on the first internal thread portion 306 and the guide pin 302 inserted into the anti-rotation column 301. Preferably, the adjustment cavity 305, the first thread portion and the anti-rotation column 301 are coaxially arranged. When adjusting the position of the T-shaped nut, lift the anti-rotation column 301 upward. At this time, the guide pin 302 presses the first spring 303 and moves along the guide through groove 307 until the bottom of the anti-rotation column 301 is higher than the end face of the opening groove of the T-shaped groove 2. Then rotate the connecting seat 103, and the bottom of the anti-rotation column 301 gradually turns to the upper end face of the T-shaped groove 2. At the same time, the short side of the clamping portion 101 also gradually turns to the position of the opening groove of the T-shaped groove 2. When the short side of the clamping portion 101 is completely parallel to the side of the opening groove width, the bottom of the anti-rotation column 301 completely falls on the upper end face of the T-shaped groove 2, and the connecting seat 103 drives the T-shaped block 1 to quickly move upward and leave the T-shaped groove 2 under the tension of the first spring 303, realizing the rapid adjustment of the position of the T-shaped nut and also realizing the convenience of replacement in a narrow space.

As shown Figure 2 in, the upward - lifting part 308 extends to the outside of the connecting seat 103 along the direction away from the internal thread groove 104. The setting of the upward - lifting part 308 facilitates the lifting operation of the anti - rotation column 301.
[0032] As shown Figure 4 、 Figure 5 and Figure 6 in, a clamping groove 106 matching with the upward - lifting part 308 is formed on the connecting seat 103, and the surface of the connecting seat 103 is flush with the surface of the upper - lifting part. This ensures that the surface of the assembled T - shaped nut is flat and at the same time reduces the adjustment space.
[0033] As shown Figure 2 、 Figure 3 and Figure 6 in, the tightening assembly includes a second spring 4, a second set - screw 5 and a locking pin 6. An installation cavity 107 is arranged in the T - shaped block 1. One end of the installation cavity 107 communicates with the bottom of the clamping part 101 through a stepped hole 109, and the other end of the installation cavity 107 is connected with the internal thread groove 104 through a second internal thread part 108. The second spring 4 and the locking pin 6 are located in the installation cavity 107. The two ends of the second spring 4 are respectively in contact with the second set - screw 5 thread - connected to the second internal thread part 108 and the large - head end of the locking pin 6. The small - head end of the locking pin 6 extends out of the connecting seat 103 through the stepped hole 109; preferably, the small - head end of the above - mentioned locking pin 6 has an arc surface, and at the same time, the internal thread groove 104, the second internal thread part 108, the installation cavity 107 and the stepped hole 109 are coaxially arranged; by arranging an anti - detachment assembly in the elastic part, where the small - head end of the locking pin 6 extends out of the connecting seat 103 and abuts against the bottom of the T - shaped groove 2, under the action of the second spring 4, the clamping part 101 of the T - shaped block 1 is jacked up and tightly pressed against the inner groove of the T - shaped groove 2, which can effectively prevent the T - shaped nut from slipping in the T - shaped groove 2.
[0034] There are internal hexagon holes in the middle of the first set - screw 304 and the second set - screw 5. The internal hexagon holes are through - holes, which are convenient for discharging liquids such as cutting fluid extending into the internal thread groove 104 and the adjustment cavity 305 during the processing.
[0035] When using the above - mentioned T - shaped nut, Figure 5Take the T-block 1 with the anti-rotation assembly 3 on one side as an example, make the long side of the clamping part 101 of the T-block 1 parallel to the opening groove of the T-slot 2, so as to insert it into the T-slot 2 from any position above the T-slot 2; press the T-block 1 downward or lift the upper part 308 of the anti-rotation column 301 while pressing the T-block 1 downward, the anti-rotation column 301 moves up and compresses the first spring 303, the relative T-block 1 moves downward, and the anti-loosening pin 6 at the lower end of the T-block 1 contacts the T The bottom of the T-slot 2 retracts under the pressing force; until the clamping part 101 completely enters the inner groove of the T-slot 2, the T-block 1 is rotated until the anti-rotation column 301 is inserted into the open groove of the T-slot 2 under the action of the first spring 303, and the lower end of the anti-rotation column 301 cooperates with the open groove of the T-slot 2 to form a anti-rotation force on the T-shaped member; at the same time, due to the action of the second spring 4, the small head end of the anti-loosening pin 6 is in close contact with the bottom of the T-slot 2, and the clamping part 101 of the T-block 1 is When the locking nut 301 is in place, the locking nut 301 will not slide relative to the T-slot 2, thus preventing the locking nut from falling off the vertically arranged T-slot 2.
