[0022] The realization, functional features and advantages of the present utility model will be further described in conjunction with embodiments with reference to the accompanying drawings. Detailed implementation manners

[0023] In order to make the objectives, technical solutions and beneficial effects of the present utility model more clear and understandable, the technical solutions in the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] In the embodiment of the present utility model, as Figures 1 - 4 shown, the steel bar connector includes: a connector main body and a positioning structure; the connector main body includes two first connection sleeves 1 arranged coaxially and at intervals, and a second connection sleeve 2 connecting the two first connection sleeves 1. The two first connection sleeves 1 and the second connection sleeve 2 jointly form a cavity for the steel bar to be inserted, and the second connection sleeve 2 is provided with an internal thread structure for fixing the steel bar; the positioning structure includes a positioning port 3 and a positioning partition 4. The positioning port 3 is formed on the side wall of the first connection sleeve 1, and the positioning partition 4 is slidably arranged in the second connection sleeve 2, and its sliding direction is consistent with the axial direction of the cavity.

[0025] Wherein, the second connection sleeve 2 is provided with a floating member, and the floating member is floatingly connected to the positioning partition 4 to control the sliding distance of the positioning partition 4 under an external force.

[0026] Specifically, in the embodiment of the present utility model, the connector main body includes two first connection sleeves 1 located on both sides, and a second connection sleeve 2 for connecting the two first connection sleeves 1. All three are hollow structures to jointly form a cavity for the steel bar to be inserted; at the same time, an internal thread structure matching the end of the steel bar is arranged on the inner wall of the second connection sleeve 2. The two steel bars are arranged in one-to-one correspondence with the two first connection sleeves 1 and can be screwed into the second connection sleeve 2 asynchronously to achieve the purpose of connecting and fixing the two steel bars. Moreover, the two first connection sleeves 1 located at the opposite ends of the second connection sleeve 2 can increase the contact area with each steel bar to improve the structural stability and strength of the connection part of the two steel bars and avoid the situation of bending deformation. Of course, the above internal thread structure can be adjusted accordingly according to the thread structure of the steel bar, and the purpose is to be thread-fitted with the steel bar, and no limitation is made here.

[0027] In the embodiment of the present utility model, the positioning structure includes a positioning port 3 and a positioning partition 4. The positioning port 3 is formed on the side wall of the first connection sleeve 1. The position state of the steel bar can be roughly judged manually by whether the steel bar passes through the positioning port 3; or a certain length is measured on the surface of the steel bar and marked. When the mark is located at or disappears from the positioning port 3, the insertion depth of the steel bar can be judged. As Figure 1 、 Figure 3As shown, the positioning ports 3 can also be set to two and are arranged in mirror symmetry along the axis of the cavity; the opposite ends of the positioning ports 3 extend to the opposite ends of the first connecting sleeve 1. The enlarged positioning ports 3 can not only reduce the overall weight of the first connecting sleeve 1, but also facilitate a more intuitive view of the insertion of the steel bars therein. Of course, the above method is applicable to experienced workers and has certain limitations in installation. Therefore, in this embodiment, a positioning partition 4 is slidably arranged in the second connecting sleeve 2. The positioning partition 4 can slide along the axis of the cavity under the action of an external force. It can not only divide the internal space of the second connecting sleeve 2 into two parts to prevent the ends of the two steel bars from touching and colliding with each other, but also finely adjust the lengths of the two parts to facilitate controlling the insertion depth of the two steel bars into the above space.

[0028] Specifically, a floating member is provided at the second connecting sleeve 2, and the floating member is floatingly connected to the positioning partition 4; thus, when one of the two steel bars is screwed into the cavity, it gradually fits with the positioning partition 4 after separating from it, and during the continuous rotation process, it pushes the positioning partition 4 to move towards the direction of the other steel bar (the other connecting sleeve). At the same time, the floating member switches from the force balance state in the natural state to the state of moving together with the positioning partition 4 after being stressed. Therefore, under the action of an external force, the sliding distance of the positioning partition 4 can be adjusted, and then the insertion depth of the steel bar can be controlled; similarly, when this steel bar is in place, the other steel bar is screwed into the remaining part of the cavity, and the steel bar can be positioned by abutting against the positioning partition 4 to control the insertion depth of the two steel bars. On the other hand, the setting of the floating member can not only provide a certain resistance when screwing in the steel bar, reasonably judge the insertion depth of the steel bar according to the change of the resistance, and improve its installation accuracy; moreover, the floating member can suspend the positioning partition 4 at any position in its sliding direction to facilitate fine-tuning the insertion depth of the two steel bars.

[0029] The utility model connects the two first connecting sleeves 1 and the second connecting sleeve 2 and constructs a cavity to increase the contact area between the steel bars and the sleeve and ensure the structural strength at the connection of the two steel bars; in addition, the insertion depth of the two steel bars can be controlled through the cooperation of the positioning ports 3 and the positioning partition 4, so that the force at the connection of the two steel bars is uniform.

[0030] As Figures 1 - 4 shown, in an embodiment, a chute 201 is provided on the side wall of the second connecting sleeve 2, and the positioning partition 4 is slidably arranged in the chute 201. Specifically, in order to define the sliding of the positioning partition 4 along the axis of the cavity, in this embodiment, a chute 201 is provided on the side wall of the second connecting sleeve 2. The chute 201 is arranged along the above axis direction, and the positioning partition 4 is slidably arranged at the chute 201 to guide its sliding. Of course, the length of the chute 201 is positively correlated with the fine adjustment depth of the steel bar. Different sizes of chutes 201 can be customized according to needs during actual processing, and no limitation is made here.

[0031] Preferably, the positioning baffle 4 is integrally formed with a mounting ear 5, and the mounting ear 5 slides into the slide slot 201; on the one hand, the positioning baffle 4 can be linked to slide by the mounting ear 5 sliding in the slide slot 201, and on the other hand, the mounting ear 5 is exposed outside the second connecting sleeve 2 through the slide slot 201, so as to more intuitively check the sliding distance of the positioning baffle 4. In other embodiments, two mounting ears 5 can be provided, and they are mirror-imaged; of course, two slide slots 201 are also provided, and the two slide slots 201 are connected to the two mounting ears 5 in a one-to-one correspondence, so as to ensure that the positioning baffle 4 is subjected to balanced force and avoid tilting.

[0032] Preferably, the plane parallel to the axis of the cavity is defined as the first plane, the plane perpendicular to the first plane is defined as the second plane, and the slide groove 201 and the positioning port 3 are projected on the first plane and the second plane respectively. In this way, it can be ensured that the slide groove 201 and the positioning port 3 are not in the same plane, and the vertically arranged slide groove 201 and the positioning port 3 can balance the force of the connector as a whole, avoiding the occurrence of a weak point of force after being located in the same plane. In other embodiments, the positions of the slide groove 201 and the positioning port 3 can be interchanged.

[0033] like Figures 2 - 4 As shown, in one embodiment, the floating member is a spring 6, and the deformation direction of the spring 6 is consistent with the axial direction of the cavity. Specifically, the two ends of the spring 6 are respectively connected to the second connecting sleeve 2 and the positioning baffle 4, and the spring 6 can be compressed when the positioning baffle 4 is pushed, so that the spring 6 applies a reverse resistance to the positioning baffle 4. At the same time, when the steel bar is stagnant at a certain place in the cavity, the positioning baffle 4 can continuously squeeze the spring 6, so that the steel bar is fixed at the corresponding position through the spring 6.

[0034] like Figures 1 - 4 As shown, in one embodiment, a stop ring 7 is provided at one end of the first connecting sleeve 1 away from the second connecting sleeve 2. The stop ring 7 is coaxially arranged with the cavity and has a notch on its circumference. Specifically, in order to further fix the steel bar and prevent it from detaching from the connector, the present embodiment provides a stop ring 7 at one end of the first connecting sleeve 1 away from the second connecting sleeve 2. The stop ring 7 has a notch. In this way, the steel bar is fixed in the cavity after passing through the stop ring 7. Due to the notch, the steel bar can rotate in the stop ring 7. Preferably, two support blocks 8 are formed on opposite sides of the notch and protrude outward. The two support blocks 8 are integrally formed with the stop ring 7 and can be detachably connected to adjust the size of the notch. The stop ring 7 and the two support blocks 8 together form a clamp structure. The clamp structure is fastened by bolts and fixes the steel bar to the first connecting sleeve 1, thereby improving the connection tightness between the steel bar and the connector and preventing the steel bar from detaching.

[0035] An anti-corrosion layer is provided on the side wall of the first connecting sleeve 1 and / or the side wall of the second connecting sleeve 2 to prevent the connector from rusting or the like when exposed to air for a long time.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
