Description

Technical Field

[0001] The utility model relates to the technical field of comb teeth, in particular to a structure of a wire-dividing comb tooth. Background Art

[0002] A wire-dividing comb is generally used for combing silk threads. Therefore, the comb teeth need to have a rotating function to avoid entanglement between the comb teeth and the silk threads. However, there are certain problems in the installation of the existing comb teeth. For example, the installation is very troublesome and bolts are required to fix the comb teeth. When using bolts for fixation, loosening will occur as the comb teeth rotate. For this reason, a structure of a wire-dividing comb tooth is proposed. Summary of the Utility Model

[0003] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by the utility model is as follows:

[0005] A structure of a wire-dividing comb tooth includes a housing. A core shaft is inserted into the interior of the housing. A second bearing is sleeved at the top end of the core shaft, and a first bearing is sleeved in the middle of the core shaft. A quick insertion slot is formed at the tail end of the core shaft. Steel balls are placed inside the quick insertion slot, and a screw is threadedly connected to the quick insertion slot.

[0006] Preferably, the size of the first bearing is larger than that of the second bearing, and both the first bearing and the second bearing are bonded to the inner wall of the housing.

[0007] Preferably, a through groove is formed at the tail of the core shaft, and the length of the through groove is longer than that of the quick insertion slot.

[0008] Preferably, there is a gap between the top end of the core shaft and the housing, and the top end of the screw abuts against the steel ball.

[0009] By adopting the above technical solution, the beneficial effects obtained by the utility model are as follows:

[0010] In the utility model, by providing a through groove at the tail of the core shaft, the tail of the core shaft is divided into two parts. At this time, by tightening the screw, the steel ball jacks open the tail, expanding the distance, realizing the quick installation of the device, so that it will not become loose during use, improving the firmness of the structural connection. At the same time, the sizes of the first bearing and the second bearing are different, so that after the second bearing is inserted into the housing, there will be no residual glue, effectively avoiding the glue sticking to the first bearing or the second bearing and causing them unable to rotate, improving the practicability of the device.

[0016] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments may be combined with each other.

[0017] The following describes a structure of the teeth of a wire dividing comb provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0018] Embodiment:

[0019] Combined with Figures 1-3 As shown, a structure of the teeth of a wire dividing comb provided by the present utility model includes a housing 110. A mandrel 120 is inserted into the interior of the housing 110. A second bearing 140 is sleeved on the top end of the mandrel 120, and a first bearing 130 is sleeved in the middle of the mandrel 120. The size of the first bearing 130 is larger than that of the second bearing 140, and both the first bearing 130 and the second bearing 140 are adhesively bonded to the inner wall of the housing 110. A quick slot 160 is formed at the tail end of the mandrel 120. A through slot that transversely cuts off the tail end of the mandrel 120 is formed at the tail of the mandrel 120. The length of the through slot is longer than that of the quick slot 160. A steel ball 150 is placed inside the quick slot 160, and a screw 170 is threadedly connected to the quick slot 160. A gap is left between the top end of the mandrel 120 and the housing 110. The top end of the screw 170 abuts against the steel ball 150.

[0020] Specifically, due to the different diameters of the first bearing 130 and the second bearing 140, glue will not overflow during installation, avoiding the glue on the second bearing 140 remaining at the position of the first bearing 130, resulting in the situation that the first bearing 130 cannot rotate, and improving the reliability of the device.

[0021] Working principle and usage process of the present utility model: First, insert the tail end of the mandrel 120 into the comb tooth connection structure of the wire dividing comb. At this time, the screw 170 is engaged with the wire dividing comb. Rotating the mandrel 120 can make the screw 170 move towards the inside of the mandrel 120, pushing the steel ball 150 to move towards the inside, thereby expanding the tail end of the mandrel 120 and firmly clamping it on the wire dividing comb to complete the installation.

[0022] In addition, when connecting the mandrel 120 and the housing 110, apply glue on the outer side of the second bearing 140, and then insert it into the inside of the housing 110. After the glue dries, bonding can be achieved and it can be started to be used.

[0023] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
