Abstract
Description
Technical Field
[0001] The utility model relates to a clamping mechanism. The utility model also relates to a child stroller connector.
Background Art
[0002] Child strollers are common products in the process of children's growth. Currently, a general child stroller can only accommodate one child. However, with the relaxation of the second-child policy, many families have two children. Therefore, when children go out, two child strollers are needed. If they are pushed separately, at least two adults are required, which is inconvenient to operate.
[0003] Chinese Patent Publication No. (CN210822426U) discloses a child stroller connector. This connector uses a connection method in which the lower cover and the upper cover are combined to clamp the side tubes of two child strollers in the left and right limiting holes formed by the upper cover and the lower cover. Then, the upper cover and the lower cover are locked by a connection knob, so as to connect the two child strollers together, facilitating one adult to push. Although this connection structure can connect two child strollers together, the shapes of the left and right limiting holes must match the side tubes of the child stroller. Otherwise, it is easy to shake due to excessive gaps and the connection is not firm. Moreover, the shapes of child strollers on the market are various, and the shapes and thicknesses of the side tubes are different. Therefore, the versatility of this child stroller connector is poor.
[0004] Therefore, the present utility model is precisely produced based on the above deficiencies.
Content of the Utility Model
[0005] The purpose of the present utility model is to overcome the deficiencies of the prior art and provide a clamping structure with a simple structure and firm clamping.
[0006] The present utility model also provides a child stroller connector with a simple structure, firm clamping and good versatility.
[0007] The present utility model is realized through the following technical solutions:
[0008] A clamping mechanism includes a seat body assembly. A flexible and bendable clamping belt is provided on the seat body assembly. A channel is also provided on the seat body assembly for the clamping belt to move therein when the clamping belt bends. When the clamping belt is threaded through the channel, a clamping space is formed between the clamping belt and the seat body assembly. A plurality of threads are provided on the clamping belt, and a nut is connected to the seat body assembly. When the nut rotates, it can cooperate with the threads to drive the clamping belt to move in the channel.
[0009] The seat body assembly includes a first seat body and a second seat body that is inserted and matched with the first seat body. The clamping belt is arranged on the second seat body, and the channel is arranged on one side of the end of the first seat body.
[0010] When the first body and the second body are connected, an annular groove is formed therebetween, and all the threads of the nut are located in the annular groove.
[0011] One side of the second body is provided with a notch that communicates with the channel and allows the bent clamping belt to move therein.
[0012] The second body and the clamping belt are an integrally injection-molded integral structure.
[0013] A children's stroller connector includes a transverse connecting rod. Clamping mechanisms as described above are respectively provided at both ends of the connecting rod, and both ends of the connecting rod are respectively connected to the seat body assembly.
[0014] The seat body assembly is slidably connected to the connecting rod so as to adjust the distance between the two clamping mechanisms.
[0015] A slideway is provided on the seat body assembly. The connecting rod is inserted into the slideway and can move therein. A locking mechanism for locking the relative positions of the two is further provided between the seat body assembly and the connecting rod.
[0016] The locking mechanism includes a lug provided on the seat body assembly. A rotating seat is hinged on the lug. A handle is provided at one end of the rotating seat, and a convex block protruding outward is provided at the other end of the rotating seat. A through hole identical to the slideway is further provided on the seat body assembly. An extrusion block that can be pushed by the convex block to extrude the connecting rod when the rotating seat rotates is provided in the through hole.
[0017] There are two convex blocks and they have arc surfaces.
[0018] Compared with the prior art, the present utility model has the following advantages: The clamping belt of the clamping mechanism of the present utility model can be deformed and bent. After the clamping belt is bent, it passes through the channel of the seat body assembly, so as to enclose a clamping space for clamping an object with the seat body assembly. By rotating the nut, the clamping belt is driven to move in the channel. When the clamping belt moves, the size of the clamping space is changed, so that the object in the clamping space can be clamped and locked. The children's stroller connector of the present utility model includes a connecting rod and the aforementioned clamping mechanisms provided at both ends of the connecting rod. Each clamping mechanism clamps and locks the side tube of a children's stroller. Regardless of the shape and thickness of the side tube of the children's stroller, it can be clamped and locked by rotating the nut, so that two children's strollers can be firmly connected together, facilitating an adult to push two children's strollers at the same time and making the pushing more convenient.

Specific Embodiment
[0024] The present utility model will be further described below with reference to the accompanying drawings:
[0025] As Figures 1 to 5 shown, a clamping mechanism 1 includes a seat body assembly 11. A flexible and bendable clamping belt 12 is provided on the seat body assembly 11. A channel 13 for the clamping belt 12 to move therein is further provided on the seat body assembly 11 when the clamping belt 12 bends. When the clamping belt 12 is threaded through the channel 13, a clamping space 14 is formed between the clamping belt 12 and the seat body assembly 11. A plurality of threads 15 are provided on the clamping belt 12. A nut 16 is connected to the seat body assembly 11 and can cooperate with the threads 15 when rotating to drive the clamping belt 12 to move in the channel 13. After the clamping belt 12 bends and is threaded into the channel 13 of the seat body assembly 11, a clamping space 14 for clamping an object is formed with the seat body assembly 11. By rotating the nut 16, the clamping belt 12 is driven to move in the channel 13. When the clamping belt 12 moves, the size of the clamping space 14 is changed, so that the object in the clamping space 14 can be clamped and locked. Therefore, regardless of the shape and thickness of the object, by rotating the nut 16, it can be clamped and locked. This clamping mechanism 1 can be used on the stroller connector. The clamping mechanism 1 is provided at both ends of the connecting rod 2. Regardless of the shape and thickness of the side tube of the stroller, by rotating the nut 16 on this side, the side tube can be clamped and locked, so that two strollers are firmly connected together, facilitating an adult to push two strollers at the same time and bringing convenience to travel. Of course, this clamping mechanism 1 can also be used alone in other occasions, such as for bundling other thin rod-shaped objects such as stationery pens.
[0026] As Figure 3 and Figure 5 shown, the seat body assembly 11 includes a first seat body 111 and a second seat body 112 that is inserted and cooperated with the first seat body 111. The clamping belt 12 is provided on the second seat body 112. The channel 13 is provided on one side of the end of the first seat body 111. In order to make the connection between the first seat body 111 and the second seat body 112 more firm, after the two are inserted, they can also be connected by riveting through a rivet 117.
[0027] As Figure 5As shown, when the first seat body 111 is connected to the second seat body 112, an annular groove 113 is formed therebetween, and all the threads of the nut 16 are located within the annular groove 113, ensuring that when the nut 16 is rotated, only the clamping belt 12 moves within the channel 13 and the nut 16 will not move back and forth.
[0028] As Figure 3 shown, a notch 114 communicating with the channel 13 and allowing the bent clamping belt 12 to move therein is provided on one side of the second seat body 112. The notch 114 can play a role in guiding and positioning, enabling the clamping belt 12 to move smoothly within the channel 13.
[0029] As Figure 3 described, the second seat body 112 and the clamping belt 12 are an integrally injection-molded integral structure, with a simple molding process and low cost.
[0030] As Figure 4 and Figure 5 shown, a children's stroller connector includes a horizontal connecting rod 2. The two ends of the connecting rod 2 are respectively provided with the aforementioned clamping mechanisms 1, and the two ends of the connecting rod 2 are respectively connected to the seat body assembly 11. When connecting two children's strollers, first, the clamping belt 12 bypasses the side tube of the children's stroller and passes through the channel 13 on the seat body assembly 11. The side tube of the children's stroller is then located within the clamping space 14. At this time, the nut 16 can be rotated. During the rotation of the nut 16, it drives the clamping belt 12 to move within the channel 13, and the clamping space 14 gradually decreases, thereby clamping and locking the side tube of the children's stroller. When the clamping mechanisms 1 at both ends of the connecting rod 2 have locked the children's strollers, the children's strollers can be pushed out for travel, facilitating one adult to push two children's strollers. Therefore, regardless of the shape and thickness of the side tube of the children's stroller, it can be clamped and locked by rotating the nut 16, making the children's stroller connector highly versatile and firmly clamped.
[0031] As Figure 4 and Figure 5 shown, the seat body assembly 11 is slidably connected to the connecting rod 2 to adjust the distance between the two clamping mechanisms 1. By relatively sliding the relative position between the connecting rod 2 and the seat body assembly 11, the distance between the two children's strollers can be changed, facilitating the user to adjust according to their own needs.
[0032] As Figure 5 shown, a slideway 115 is provided on the seat body assembly 11. The connecting rod 2 is inserted into the slideway 115 and can move within the slideway 115. A locking mechanism 3 for locking their relative positions is further provided between the seat body assembly 11 and the connecting rod 2. When the distance between the two children's strollers is adjusted by sliding the connecting rod 2 relative to the seat body assembly 11, the distance can be locked by the locking mechanism 3.
[0033] As Figure 4 and Figure 5 shown, the locking mechanism 3 includes a lug 31 provided on the seat body assembly 11. A rotating seat 32 is hinged on the lug 31. One end of the rotating seat 32 is provided with a handle 33, and the other end of the rotating seat 32 is provided with a convex block 34 protruding outward. There are two convex blocks 34 and they have arc surfaces. The seat body assembly 11 is also provided with a through hole 116 identical to the slideway 115. An extrusion block 35 that can be pushed by the convex block 34 to extrude the connecting rod 2 is provided in the through hole 116. When it is necessary to adjust the distance between two baby strollers, the handle 33 is toggled, the rotating seat 32 rotates, the convex block 34 releases the extrusion block 35, the extrusion block 35 releases the connecting rod 2, and the connecting rod 2 can slide in the slideway 115 on the seat body assembly 11 to change its position. When adjusted to a suitable position, the handle 33 is pushed again, the rotating seat 32 rotates, the convex block 34 pushes and presses the extrusion block 35 again, and the extrusion block 35 extrudes the connecting rod 2, so that the connecting rod 2 tightly abuts against the inner side wall of the slideway 115, thereby realizing the locking of the relative position between the connecting rod 2 and the seat body assembly 11. The entire unlocking or locking operation is very convenient and fast.
[0034] The above has described this embodiment in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiment. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
