Description

Technical Field

[0001] The utility model relates to the technical field of air pipe joints, in particular to a quick-insert anti-retraction joint and a vehicle suspension air storage system. Background Art

[0002] The gear disc used to clamp the trachea in traditional trachea joints is a flat structure. This flat design can easily cause the gear disc to deform during the processing and assembly process. At the same time, the fixed teeth of the gear disc are exposed outside the gear disc, which can easily damage the gear disc teeth and result in insufficient force to clamp the trachea during installation. Utility Model Content

[0003] The technical problem to be solved by the utility model is how to prevent the air pipe from retreating from the joint.

[0004] The utility model solves the above technical problems through the following technical means:

[0005] A quick-insert, anti-retraction connector with a bell mouth at one end of the connector body; the chuck includes a cone portion adapted to the bell mouth and a non-return element disposed on the conical surface of the cone portion. The non-return element on the conical surface of the cone portion allows the air tube to be squeezed and deformed during assembly of the connector body and chuck, thereby locking the air tube.

[0006] Furthermore, the non-return unit includes a plurality of non-return grooves circumferentially opened on the cone portion, and the non-return grooves are located on the same circumference or staggered on different circumferences.

[0007] The utility model provides a check groove on the conical surface of the chuck, whether continuous or discontinuous, so that when the joint body and the chuck are assembled, the air pipe is squeezed and deformed into the check groove, and the barbed notch can lock the air pipe to prevent it from retreating.

[0008] Furthermore, the chuck also includes a disc surface, and the disc surface is connected to the large diameter end of the cone portion through a neck.

[0009] Furthermore, the diameter of the neck portion is the same as or slightly smaller than the diameter of the larger diameter end of the cone portion, and the neck portion has a certain height. The neck portion of the present invention has a certain height, so that an adjustable gap is formed between the end face of the connector body and the disc surface, thereby preventing the cone surface from loosening due to vibration and keeping the chuck in a locked state.

[0010] This embodiment also provides a vehicle suspension air storage system, including the above-mentioned quick-insert anti-retraction joint, an air storage tank, and a bladder spring; one end of the air pipe is connected to the air outlet of the air storage tank through the quick-insert square leg joint, and the other end is connected to the bladder spring.

[0011] The advantages of the present invention are:

[0012] The utility model provides a non-return unit on the conical surface of the conical part, so that when the joint body and the chuck are assembled, the trachea is squeezed to deform the trachea, thereby clamping the trachea.

[0013] The utility model provides a check groove on the conical surface of the chuck, whether continuous or discontinuous, so that when the joint body and the chuck are assembled, the air pipe is squeezed and deformed into the check groove, and the barbed notch can lock the air pipe to prevent it from retreating.

[0014] The neck of the utility model has a certain height, so that an adjustment gap is formed between the end face of the joint body and the disc surface, thereby preventing the cone surface from loosening due to vibration and keeping the chuck in a locked state at all times.

[0017] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0018] Example 1

[0019] This embodiment describes a quick-insert anti-retraction connector, such as Figure 1 As shown, it includes a connector body 1 and a chuck 2; the connector body 1 is provided with a bell mouth 11; the chuck 2 includes a cone portion 21 adapted to the bell mouth 11; and a non-return unit is provided on the cone surface of the cone portion 21.

[0020] In this embodiment, the cone portion 21 is a frustum, and the non-return unit provided on its cone surface is at least one continuous non-return groove 22 provided in the circumference of the cone portion 21, or a discontinuous non-return groove 22 provided in the circumference of the cone portion 21. If the non-return groove 22 is discontinuous, the multiple sections of the non-return groove 22 can be located on the same circumference or staggered on different circumferences. In order to achieve the non-return effect, the non-return groove 22 in this embodiment forms a barb structure toward the notch of the small diameter end of the cone portion 21, such as Figure 1 、 Figure 2As shown, the cross-sectional shape of the check groove 22 is: an acute angle at the bottom of the groove, the groove wall toward the small diameter end of the cone portion 21 is parallel to the end face of the cone portion 21, or slightly inclined toward the large diameter end from the bottom of the groove to the groove mouth, and the groove wall of the check groove 22 toward the large diameter end of the cone portion 21 is inclined toward the large diameter end from the bottom of the groove to the groove mouth, thereby forming a barb structure to prevent the trachea 3 from retreating.

[0021] When using, such as Figure 2 As shown, in this embodiment, the toothed disc is designed with a tapered bell mouth 11, and the chuck 2 is quickly inserted into the trachea 3 by using the self-guided tapered bell mouth 11. The rotation of the thread on the joint generates a force to axially squeeze the end face of the chuck 2, so that the chuck 2 is forced to be inserted into the depth of the trachea 3. As the thread is screwed in, the inner taper of the joint and the outer taper of the chuck 2 are squeezed and compressed, and the trachea 3 enters the non-return groove 22 on the inner taper of the joint, embeds into the trachea 3, and firmly fastens the trachea 3 to prevent the trachea 3 from retreating.

[0022] Example 2

[0023] This embodiment is based on embodiment 1. Figure 2 As shown, a neck 24 is further connected between the disk surface 23 and the large diameter end of the cone portion 21. The diameter of the neck 24 is the same as that of the large diameter end of the cone portion 21, but can also be slightly smaller. In this embodiment, for ease of processing, a cylindrical body with the same dimensions as the large diameter end is used as the neck 24. Since the neck 24 has a certain height, when the joint is fixed to the chuck 2, a certain adjustment gap 25 is provided between the cross section of the joint and the disk surface 23. This adjustment gap 25 prevents the cone surface from loosening due to vibration, and keeps the chuck 2 locked at all times.

[0024] Example 3

[0025] The anti-retraction connector described in Example 1 or Example 2 is used in a vehicle suspension system. The connector is used to connect an air tank to an air pipe, the other end of which is connected to a bladder spring. The connector prevents the air pipe from falling off the air tank, thereby ensuring the normal operation of the suspension system.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
