[0025] The technical solutions of the present application are further illustrated below by specific embodiments in conjunction with the drawings.

[0026] As Figure 1The utility model provides a kind of connecting device, including connecting seat 1 and locking assembly 2, connecting seat 1 is provided with at least two chambers 11, at least two locking assemblies 2 are provided in each chamber 11, each locking assembly 2 includes locking piece 21, elastic piece 22 and connecting shaft 23, locking piece 21 is rotatably arranged in the side wall of chamber 11 by connecting shaft 23, when needing to connect each to-be-connected piece, each to-be-connected piece can be inserted into each chamber 11 respectively, so that locking piece 21 rotates around connecting shaft 23 and drives elastic piece 22 to be energy storage state, under the elastic force of elastic piece 22, locking piece 21 can lock the to-be-connected piece inserted into chamber 11, i.e. locking assembly 2 can realize the locking of to-be-connected piece while inserting to-be-connected piece, the locking position of to-be-connected piece is initial insertion position, the connection precision between each to-be-connected piece is higher, can be applicable to various construction operations requiring connection precision, and the connection between each to-be-connected piece can be realized by inserting to-be-connected piece into chamber 11, and the connection efficiency between each to-be-connected piece is higher.

[0027] Two locking assemblies 2 can be provided in each chamber 11, so that locking assembly 2 can be fixed and limited to to-be-connected piece from different directions, to ensure that the stress of to-be-connected piece in two directions is uniform, locking assembly 2 can be installed evenly along the inner wall of chamber 11, to enhance the clamping effect of to-be-connected piece and ensure that the stress of to-be-connected piece in each direction is uniform, in other embodiments, multiple locking assemblies 2 can be evenly arranged along the inner wall of each chamber 11 in circumferential direction, without too much limitation here.

[0028] Locking assembly 2 includes locking piece 21, elastic piece 22 and connecting shaft 23, to make the connecting device achieve automatic locking effect after inserting to-be-connected piece, single locking piece 21 needs to be matched with single connecting shaft 23 and at least one elastic piece 22, when connecting heavier or larger diameter to-be-connected piece, the number of elastic piece 22 matched with single locking piece 21 can be appropriately increased. In the locking process, with the help of the existence of connecting shaft 23 and elastic piece 22, there is a rotating space between locking piece 21 and the inner wall of chamber 11, to-be-connected pieces of different diameter ranges can be connected by the connecting device. Avoidance groove 111 can be arranged in chamber 11, the existence of avoidance groove 111 can improve the rotating process of locking piece 21, to avoid the rotating process of locking piece 21 in chamber 11 from being disturbed.

[0029] In an embodiment, the elastic member 22 is a spring, one end of the spring is arranged on the side wall of the cavity 11, and the other end is in abutment with the locking member 21. After the to-be-connected member is inserted into the cavity 11, the spring can exert pressure on the locking member 21 in contact with the spring, so as to promote the locking member 21 to rotate along the direction of the wall surface on the side where the locking member 21 is located. When the locking member 21 rotates, the locking member 21 will compress the spring in abutment with the locking member 21. By virtue of the restoring property of the spring itself, the spring will drive the locking member 21 to rotate along the direction of the wall surface away from the side where the locking member 21 is located, and the locking member 21 will lock the to-be-connected member, so as to fix the position of the to-be-connected member in the cavity 11, and avoid the to-be-connected member from loosening or falling off. That is, after the process of inserting the to-be-connected member into the cavity 11 is completed, the locking process of the connecting device on the to-be-connected member is also completed. In essence, the process of inserting the to-be-connected member into the cavity 11 is a process of overcoming the elastic force of the spring. In order to achieve the effect of saving labor, the spring can be arranged at a position where the distance between the spring and the connecting shaft 23 is greater than the distance between the spring and the end of the locking member 21 away from the connecting shaft 23.

[0030] In other embodiments, the elastic member 22 can be a torsion spring, the torsion spring is sleeved on the connecting shaft 23, one end of the torsion spring is arranged on the side wall of the cavity 11, and the other end is connected with the locking member 21. After the to-be-connected member is inserted into the cavity 11, the to-be-connected member can exert pressure on the locking member 21 in contact with the to-be-connected member, so as to promote the locking member 21 to rotate along the direction of the wall surface on the side where the locking member 21 is located. The rotating process of the locking member 21 will cause the torsion spring to be elastically deformed. By virtue of the restoring property of the torsion spring itself, the locking member 21 can rotate along the direction of the wall surface away from the side where the locking member 21 is located, so as to achieve the locking effect of the locking member 21 on the to-be-connected member.

[0031] Specifically, the locking member 21 is provided with a pressing surface 211. When the to-be-connected member is inserted into the cavity 11, the locking member 21 locks the to-be-connected member under the action of the elastic member 22, and the pressing surface 211 is pressed against the outer wall surface of the to-be-connected member. The opening relative to the opening of the cavity 11 can be arranged obliquely, so that the opening surrounded by the pressing surface 211 arranged on each locking member 21 is smaller than the opening area of the cavity 11. When the to-be-connected member continuously moves in the insertion direction, the elastic deformation amount of the elastic member 22 continuously increases, the locking effect of each locking member 21 on the to-be-connected member under the elastic restoring property of the elastic member 22 is stronger, and the connecting and fixing effect of the connecting device on the to-be-connected member is better.

[0032] The chamber 11 can include a guide cavity 112 and a limiting cavity 113, the to-be-connected member can enter the guide cavity 112 through the limiting cavity 113, the locking assembly 2 is arranged in the guide cavity 112, the guide cavity 112 is in a contraction shape along the insertion direction of the to-be-connected member, that is, the guide cavity 112 is in a conical shape, the conical guide cavity 112 can be matched with the pressing surface 211 arranged in an inclined direction compared with the opening of the chamber 11, to provide a guiding effect for the insertion of the to-be-connected member, and as the insertion depth increases, the gap between the to-be-connected member and the side wall of the guide cavity 112 gradually decreases, so that the connection between the to-be-connected member and the guide cavity 112 is more tight, and the reliability and stability of the connection are improved, and in combination with the elastic member 22 connected to the locking member 21 and the side wall of the chamber 11 and the limiting cavity 113, the connecting device can effectively prevent the to-be-connected member from loosening after being inserted into the connecting device, and improve the integrity and safety of the to-be-connected member after being connected with the connecting device.

[0033] The connecting device can be applied to the connection process in various construction technical fields, and the to-be-connected member can be a reinforcing bar. For example, when there is a requirement for long-distance arrangement of reinforcing bars in a construction area or there is a difference in the load bearing demand of reinforcing bars in different parts of the area, the connecting device can be used to connect multiple reinforcing bars. To enhance the pressing effect of the pressing surface 211 on the reinforcing bar, threads can be machined on the pressing surface 211, which can be matched with the threads on the outer surface of the reinforcing bar. Alternatively, a threaded interface capable of being sleeved on the insertion end of the reinforcing bar can be pre-machined, and a toothed structure 212 is machined on the pressing surface 211. After multiple reinforcing bars with threaded interfaces are inserted into different chambers 11, the toothed structure 212 on the pressing surface 211 can be clamped into the threaded structure of the threaded interface. At this time, the pressing surface 211 can be tightly connected with the outer surface of the reinforcing bar, and the connecting device can realize the fixation of multiple reinforcing bars. To enhance the fixation effect of the reinforcing bar in the connecting device, the shape of the threaded interface can be machined to correspond to the shape of the guide cavity 112. In addition, to enhance the versatility of the connecting device, the connecting device is produced in multiple models to meet the connection requirements under different construction conditions, and at least two chambers 11 are arranged in each connecting device to meet the connection requirements of different construction operations, such as connection angle or connection length, of each to-be-connected member.

[0034] Since at least two chambers 11 are arranged in the connecting device, to improve construction efficiency during actual construction, multiple construction personnel usually construct at the opening positions of different chambers 11 at the same time. To avoid collision or mutual interference of each to-be-connected member during the connection process, a positioning surface 12 can be arranged on the inner wall of the chamber 11. When the connecting device is used, the to-be-connected member is inserted into the chamber 11 until the to-be-connected member abuts against the positioning surface 12, and then the force acting on the to-be-connected member is stopped. At this time, the elastic member 22 can drive the locking member 21 to lock the to-be-connected member by relying on the reset characteristic thereof, and the positioning surface 12 can ensure the orderly progress of the connection process between each chamber 11.

[0035] In order to facilitate the installation of the plurality of locking pieces 21, the connecting shaft 23 and the elastic piece 22 into the connecting seat 1, the connecting seat 1 can comprise at least two detachably connected seat bodies, one end of the connecting shaft 23 is arranged on one seat body, and the other end is arranged on the adjacent other seat body, and the plurality of locking pieces 21, the connecting shaft 23 and the elastic piece 22 are respectively installed on the two seat bodies, and then the seat bodies are assembled, so that the complete connecting device can be obtained, the fixing of the connecting shaft can be realized, the subsequent locking assembly 2 can work normally, and the locking process of the to-be-connected pieces in the cavity 11 can be successfully realized. The connecting device provided by the utility model does not need to consider the influence of weather and other factors, can be suitable for various construction environments, and only needs to insert each to-be-connected piece into each cavity 11 to complete the connecting process, the connecting efficiency is high, the connecting process does not cause the waste of the to-be-connected pieces compared with the binding connection, and the utilization efficiency of materials can be effectively improved.
