Description

Technical Field

[0001] The utility model relates to the technical field of mechanical assembly fasteners, in particular to an embedded combined fastener. Background Art

[0002] The existing mechanical assembly fasteners have a relatively simple structure, poor assembly and fixing effects, and not very ideal assembly accuracy. Due to defects in the structure of the fasteners themselves, the assembly process is rather cumbersome, seriously affecting work efficiency. In this regard, the publication number CN202301396U discloses an arbitrarily positioned embedded combined fastener, which mainly includes a fastener body. An arc surface is formed on the lower surface of the fastener body, and at least one friction limiting fin is formed at the arc surface. The edge of the friction limiting fin is an arc surface. At least two embedded bumps are provided on the upper surface of the fastener body. A gasket assembly part is formed between the two embedded bumps, and a screw assembly hole is formed at the gasket assembly part. A gasket is provided in the recessed part, and a round hole corresponding to the screw assembly hole is provided at the gasket. The screw penetrates through the round hole and the screw assembly hole. The product has a reasonable structure and can greatly improve the efficiency of system assembly and installation. It can effectively ensure the assembly quality, ensure the same direction of the fastener and the support profile, and is easy to operate. The fastener can be added to the required structure at any time and slid to the accurate installation position, thus ensuring quality, improving work efficiency, and being convenient to operate, and having good practicability.

[0003] For the arbitrarily positioned embedded combined fastener disclosed in the above technology, by sliding and inserting the fastener body into the T-shaped chute of the profile and using the external arc of the fastener body to fit and adhere to the T-shaped chute of the profile, the position of the fastener body can be adjusted, and the operation is simple. However, it still has the following deficiencies: 1. Since the external arc of the fastener body is adapted to and directly adheres and rubs against the T-shaped chute of the profile, a large squeezing and grinding phenomenon is likely to occur when adjusting the position of the fastener body, and the smoothness and ease of adjustment are not ideal; 2. It cannot conveniently and quickly unlock and lock the fastener body before and after use without tools. A special tool needs to be used to operate the screw alone to make it tightly fit in the chute, and the unlocking and locking convenience before and after adjustment is not ideal. Improvements are needed. In view of this, this application proposes an embedded combined fastener to solve the above problems. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 4 shown, an embedded combined fastener proposed in this embodiment includes a profile 100 having a T-shaped chute 101 and an embedded combined fastener body adapted to the T-shaped chute 101. Both the front and rear sides of the T-shaped chute 101 are open, and the lower parts of the inner walls on both sides of the T-shaped chute 101 are arc-shaped structures. The embedded combined fastener body includes a loop-shaped slider 1 inserted into the T-shaped chute 101. The top of the loop-shaped slider 1 is fixedly connected with an internal thread sleeve 4. The top of the internal thread sleeve 4 penetrates through the middle of the T-shaped chute 101 and extends above the profile 100. A screw 5 is screwed into the internal thread sleeve 4, and a nut is sleeved on the screw 5;

[0025] Both the bottom sides of the loop-shaped slider 1 are arc-shaped structures and are movably nested with two first anti-wear balls 2. The first anti-wear balls 2 are in movable contact with the arc-shaped structure inside the T-shaped chute 101. Both sides of the top of the loop-shaped slider 1 are movably embedded with two second anti-wear balls 3 that are in movable contact with the inner wall of the top of the T-shaped chute 101. The provided loop-shaped slider 1 is used for performing an anti-loosening and anti-detaching work after being inserted into the T-shaped chute 101 of the profile 100. The provided first anti-wear balls 2 and second anti-wear balls 3 are used for allowing the loop-shaped slider 1 to move smoothly and easily in the T-shaped chute 101 for anti-wear when the fastening position needs to be adjusted;

[0026] A lifting plate 6 is arranged inside the loop-shaped slider 1. A pressure-regulating elastic tensioning assembly fixedly connected to the bottom of the lifting plate 6 is installed on the bottom inner wall of the loop-shaped slider 1. A vertical guiding and pressing assembly is fixedly connected to the top of the lifting plate 6. Both the loop-shaped slider 1 and the internal thread sleeve 4 are slidably sleeved on the vertical guiding and pressing assembly. On both sides of the top of the lifting plate 6, a squeezing and locking assembly that tightly contacts the top inner wall of the T-shaped chute 101 is fixedly connected. The pressure-regulating elastic tensioning assembly is used to elastically tension the lifting plate 6 upward. The vertical guiding and pressing assembly is used for personnel to drive the lifting plate 6 to move downward by simply pressing on the upper part. The squeezing and locking assembly is used to tightly squeeze against the top inner wall of the T-shaped chute 101 when the lifting plate 6 is elastically tensioned, so as to lock the loop-shaped slider 1, and is used to release the locked state when the lifting plate 6 moves downward.

[0027] Specifically, the pressure-regulating elastic tensioning assembly includes a rectangular block 12. A rectangular chute 10 is opened on the bottom inner wall of the loop-shaped slider 1. The rectangular block 12 is slidably sleeved in the rectangular chute 10. Between the top of the rectangular block 12 and the bottom of the lifting plate 6, two compression springs 9 in a compressed state are fixedly connected. A T-shaped screw rod 11 is rotatably embedded at the bottom of the loop-shaped slider 1. Among them, a circular hole is opened at the bottom of the loop-shaped slider 1, and a bearing is fixedly sleeved in the circular hole. The inner side of the inner ring of the bearing is fixedly connected to the outer side of the T-shaped screw rod 11, achieving the effect of rotatably installing the T-shaped screw rod 11. The rectangular block 12 is threadedly sleeved on the T-shaped screw rod 11. Among them, a thread groove threadedly connected to the T-shaped screw rod 11 is opened at the bottom of the rectangular block 12. By using the threaded connection relationship between the T-shaped screw rod 11 and the thread groove, it achieves the effect of conveniently driving the rectangular block 12 to move up and down when the T-shaped screw rod 11 rotates; the arranged rectangular chute 10, rectangular block 12, T-shaped screw rod 11 and compression spring 9 cooperate. By using the compression spring 9, the lifting plate 6 is elastically tensioned upward. By rotating the T-shaped screw rod 11 to drive the rectangular block 12 to move up and down, and using the upward compression of the compression spring 9 by the upward movement of the rectangular block 12, the initial compression degree of the compression spring 9 can be adjusted, so as to adjust the tensioning elastic force of the compression spring 9 on the lifting plate 6, improve the tensioning stability, and overcome the phenomenon that the elastic force of the subsequent compression spring 9 becomes weak due to elastic fatigue, and improve the long-term use stability.

[0028] Furthermore, the vertical guiding and pressing assembly includes two vertical guiding rods 8 fixedly connected to the top of the lifting plate 6. The top ends of the two vertical guiding rods 8 both extend above the internal thread sleeve 4 and are fixedly connected to the same annular pressing block 7. The annular pressing block 7 is slidably sleeved on the screw 5. Both the loop-shaped slider 1 and the internal thread sleeve 4 are slidably sleeved on the two vertical guiding rods 8. Among them, two vertical guiding holes are opened on the top inner wall of the loop-shaped slider 1 and the top of the internal thread sleeve 4. The vertical guiding holes are slidably sleeved on the outer sides of the corresponding vertical guiding rods 8, achieving the effect of allowing the vertical guiding rods 8 to pass through and guiding their vertical sliding; the arranged vertical guiding rods 8 and annular pressing block 7 cooperate. By simply pressing the annular pressing block 7 from the upper part, the annular pressing block 7 drives the lifting plate 6 to move downward through the vertical guiding rods 8, achieving the effect of conveniently operating the movement of the lifting plate 6 by simply pressing from the upper part.

[0029] Further, the extrusion and locking assembly includes a top block 13 fixedly connected to the top of the lifting plate 6. The top of the top block 13 extends above the return-shaped slider 1 and is adhesively fixed with an anti-slip rubber block 14. The top of the anti-slip rubber block 14 is in tight contact with the inner wall of the top of the T-shaped chute 101. The return-shaped slider 1 is slidably sleeved on the two top blocks 13. Among them, two rectangular through holes are formed in the inner wall of the top of the return-shaped slider 1 and are respectively slidably sleeved on the outer sides of the corresponding top blocks 13, which has the effect of allowing the top blocks 13 to pass through and guiding their vertical sliding; the arranged top block 13 and the anti-slip rubber block 14 cooperate, and the elastic tensioned lifting plate 6 drives the two anti-slip rubber blocks 14 to be tightly pressed against the inner wall of the top of the T-shaped chute 101 through the two top blocks 13. By using the squeezing friction between the anti-slip rubber block 14 and the T-shaped chute 101, the locking of the return-shaped slider 1 is realized.

[0030] The usage method of this embodiment is as follows: Before the return-shaped slider 1 slides and is embedded in the T-shaped chute 101 of the profile 100, first press down the annular pressing block 7 so that it drives the lifting plate 6 to move downward through the vertical guide rod 8 and compresses the compression spring 9. The lifting plate 6 drives the two top blocks 13 to move downward, and the top blocks 13 drive the corresponding anti-slip rubber blocks 14 to move downward. At this time, directly insert the return-shaped slider 1 into the T-shaped chute 101 from one end of the profile 100, and then release the pressing force on the annular pressing block 7. At this time, the compression spring 9 in the compressed state drives the lifting plate 6 to move upward. The lifting plate 6 drives the two anti-slip rubber blocks 14 to be tightly pressed against the inner wall of the top of the T-shaped chute 101 through the two top blocks 13. By using the squeezing friction between the anti-slip rubber block 14 and the T-shaped chute 101, the locking of the return-shaped slider 1 is realized, making it convenient to quickly and conveniently embed the return-shaped slider 1 into the T-shaped chute 101 of the profile 100;

[0031] When it is necessary to adjust the fixed position of the loop slider 1 in the T-shaped chute 101, press down the annular pressing block 7 to drive the lifting plate 6 to move downward through the vertical guide rod 8, and compress the compression spring 9. The lifting plate 6 drives the two anti-slip rubber blocks 14 to move downward through the two top blocks 13, releasing the squeezing and locking state. At this time, moving the annular pressing block 7 forward or backward can drive the loop slider 1 to move back and forth through the vertical guide rod 8 for adjustment. The loop slider 1 drives the four first anti-wear balls 2 and the four second anti-wear balls 3 to roll on the inner wall of the T-shaped chute 101. After adjustment, release the pressing force on the annular pressing block 7 again. The compression spring 9 in the compressed state drives the two anti-slip rubber blocks 14 to be tightly squeezed against the top inner wall of the T-shaped chute 101 through the lifting plate 6 and the two top blocks 13 in sequence, locking the loop slider 1 again. Through the arrangement of the four first anti-wear balls 2 and the four second anti-wear balls 3, while anti-wearing and supporting the loop slider 1 in the T-shaped chute 101, it can avoid the frictional force caused by its contact with the inner wall of the T-shaped chute 101, making it convenient to adjust its anti-wearing movement smoothly and easily, avoiding the phenomenon of jamming due to excessive frictional force, and improving the smoothness and ease of adjustment; and by simply pressing and releasing to unlock and lock the loop slider 1, it is convenient to unlock, adjust and lock the loop slider 1 quickly without tools before and after use, without the need to use special tools for operation, improving the convenience of unlocking and locking before and after adjustment;

[0032] Before insertion, the operator can drive the rectangular block 12 to move up and down in the rectangular chute 10 by rotating the T-shaped screw 11, and use the upward movement of the rectangular block 12 to compress the compression spring 9 upward, which can adjust the initial compression degree of the compression spring 9, so as to adjust the tension force on the lifting plate 6 and improve the tension stability. In addition, by using the method of adjustable elastic tension, it can also overcome the phenomenon of weakening of the elastic fatigue force of the subsequent compression spring 9 and improve the long-term use stability; after the set screw 5 is screwed into the inner thread sleeve 4 after the external installation part is screwed and fixed on the lower surface of the head of the screw 5 by using a nut.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
