Description

Technical Field

[0001] The utility model relates to the technical field of throat clamps, in particular to a combined throat clamp. Background Art

[0002] The hose clamp is a screw-driven fastening device, which is mainly used to connect and fasten various soft and hard pipes. The hose clamp is widely used in many industries, such as agricultural irrigation, small machinery, and automobile pipeline connections.

[0003] Most existing throat hoops are integrally formed. When connecting a pipe, a screw is passed through the connection holes at both ends of the throat hoops, and then the nut threaded on the screw is rotated to bring the two ends of the throat hoops closer to each other, thereby tightly holding the throat hoops on the outer wall of the pipe. However, when connecting pipes with existing throat hoops, there are the following problems: after the throat hoops have been used for a period of time, the screw and the connection hole are no longer concentric, causing the screw and the connection hole to be easily bent and deformed in the axial direction. Utility Model Content

[0004] The utility model aims to provide a combined throat clamp to solve the problems raised in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combined throat clamp comprises:

[0006] Hose clamp body;

[0007] The center of the throat clamp body is provided with a circular groove for accommodating the pipe, and the two ends of the throat clamp body are bent away from the center of the circular groove to form ears, and the ears are provided with connecting notches;

[0008] The locking block includes a right-angle plate and a tongue block. The tongue block is arranged at the lower part of the right-angle plate. The tongue block is configured so that the side surface of the tongue block is parallel to the outer side surface of the right-angle plate. The side surfaces of the tongue block and the right-angle plate are provided with concentric connecting holes. The tongue block can pass through the connecting notch and keep the outer side surfaces of the two right-angle plates always parallel.

[0009] A screw rod passes through all the connection holes located on the same axis, and a nut is threadedly connected to the end of the screw rod.

[0010] Furthermore, a rubber sleeve is arranged in the circular groove.

[0011] Furthermore, a first transition arc is provided at the connection between the tongue block and the right-angle plate.

[0012] Furthermore, a second transition arc is provided at the right-angle connection of the right-angle plate.

[0013] Furthermore, the ear portion is provided with a plurality of connection notches, and the plurality of connection notches are arranged at equal intervals along the axis of the circular groove portion;

[0014] There are a plurality of tongue blocks arranged on each of the right-angle plates, and the plurality of tongue blocks correspond one-to-one to the plurality of connection notches.

[0015] Furthermore, a limiting protrusion is also provided at the lower part of the right angle plate;

[0016] A limiting groove is arranged on the ear, and the limiting groove is matched with the limiting protrusion.

[0017] Compared with the prior art, the utility model provides a combined throat clamp, which has the following beneficial effects:

[0018] The combined throat clamp is provided with a right-angle plate and a throat clamp body.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] See also Figure 1-Figure 4 As shown, a combined throat clamp includes a throat clamp body 100, a locking block 200 and a screw 400. The center of the throat clamp body 100 has a circular groove portion 110 for accommodating a pipe. Both ends of the throat clamp body 100 are bent in a direction away from the center of the circular groove portion 110 to form an ear portion 120. The ear portion 120 is provided with a connecting notch 121, a locking block 200, and the locking block 200 includes a right-angle plate 210 and a tongue block 220. The tongue block 220 is arranged at the lower part of the right-angle plate 210. The tongue block 220 is configured so that the side surface of the tongue block 220 is parallel to the outer side surface of the right-angle plate 210. The sides of the tongue block 220 and the right-angle plate 210 are provided with concentric connecting holes 230. The tongue block 220 can pass through the connecting notch 121 and make the outer side surfaces of the two right-angle plates 210 always remain parallel. The screw 400 passes through all the connecting holes 230 located on the same axis, and the end of the screw 400 is threadedly connected with a nut 410.

[0027] The specific usage and function of this embodiment are as follows:

[0028] When in use, the staff first disassembles the three components of the throat clamp body 100, the locking block 200 and the screw 400, and then puts the throat clamp body 100 on the outside of the pipe to be connected (that is, the pipe is located in the circular groove portion 110), and then installs the two locking blocks 200 on the throat clamp body 100, and finally passes the two locking blocks 200 through the screw 400, and finally threadedly connects the nut 410 to the screw 400, and then increases the clamping force between the pipe and the throat clamp body 100. Specifically, the staff rotates the nut 410 with a wrench with one hand and fixes the screw 400 with the other hand, so that the nut 410 moves toward the center of the screw 400, and the nut 410 pushes one of the locking blocks 200 close to the other locking block 200, so that the two ears 120 of the throat clamp body 100 are close to each other, thereby increasing the clamping force between the throat clamp body 100 and the pipe.

[0029] It can be understood that the right-angle plate 210 and the ear 120 are slidably abutted via the connecting groove 121 rather than fixedly connected. Therefore, when the two ends of the throat clamp body 100 are close to each other, the two right-angle plates 210 can adaptively adjust their angles so that the two right-angle plates 210 always remain parallel to each other. Therefore, the screw 400 and the connecting hole 230 can always remain concentric, thereby avoiding bending deformation of the screw 400 in its axial direction.

[0030] In a further embodiment, Figure 2 As shown, a rubber sleeve 500 is disposed in the circular groove 110 , and the rubber sleeve 500 is used to protect the pipeline.

[0031] In a further embodiment, Figure 3As shown, a first transition arc 240 is provided at the connection between the tongue block 220 and the right-angle plate 210 . The first transition arc 240 is provided to enable the right-angle plate 210 to be smoothly installed into the connection slot 121 and to be smoothly removed from the connection slot 121 .

[0032] In a further embodiment, Figure 3 As shown, a second transition arc 250 is provided at the right-angle connection of the right-angle plate 210 .

[0033] The second transition arc 250 has the same function as the first transition arc 240 , which is to enable the right-angle plate 210 to be smoothly installed into the connection slot 121 and to be smoothly removed from the connection slot 121 .

[0034] In a further embodiment, Figure 3 and Figure 4 As shown, the ear portion 120 is provided with a plurality of connection slots 121 , which are arranged at equal intervals along the axis of the circular groove portion 110 , and a plurality of tongue blocks 220 are arranged on each right-angle plate 210 , and the plurality of tongue blocks 220 correspond one-to-one to the plurality of connection slots 121 .

[0035] The connection notches 121 and tongue blocks 220 are provided with multiple purposes, which is to disperse the force and increase the stability of the connection.

[0036] In a further embodiment, Figure 3 and Figure 4 As shown, a limiting protrusion 260 is further provided at the lower portion of the right-angle plate 210 , and a limiting groove 122 is provided on the ear portion 120 , and the limiting groove 122 is adapted to the limiting protrusion 260 .

[0037] The limiting protrusion 260 and the limiting groove 122 are provided to limit the relative movement between the right-angle plate 210 and the throat clamp body 100 along the axial direction of the throat clamp body 100 .

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
