Description
Technical Field
The utility model relates to the field of mechanical engineering, in particular to a binding clip, a clamp release clamp and a clamp assembly.
Background
In many places in the automobile, the connection is carried out through pipe fittings, such as a water pipe, an air inlet pipe, an oil pipe and the like. Because the working condition of the automobile has temperature difference, the pipe fitting expands with heat and contracts with cold, and the tightness of the elastic clamp can change along with the change of the expansion with heat and the contraction with cold of the pipe fitting, thereby the pipe fitting is connected in a sealing way.
Elasticity clamp among the prior art includes pre-expansion type clamp and non-pre-expansion type clamp, and the difference of two kinds of clamps lies in:
the non-pre-expansion type clamp is in a contraction state in an initial state, and is converted into a pre-expansion state from the contraction state by using a tool when in use, and then the non-pre-expansion type clamp is sleeved on the pipe clamp for application.
The initial state of the pre-expansion type clamp is a pre-expansion state, so that the pre-expansion type clamp can be directly sleeved on the pipe clamp for application, and the pre-expansion type clamp is more convenient to use compared with a non-pre-expansion type clamp.
However, during the manufacturing process of the pre-expanded clamp, the pre-expanded clamp still needs to be manually turned from the release state to the pre-expanded state by means of a tool. The current pliers that generally adopt will open type clamp in advance changes from the release state into the state of opening in advance, specifically as follows: one hand holds the pre-expansion type clamping hoop, the other hand holds the pliers, the tooth sections on the pliers are used for being clamped at the free ends of the pre-expansion type clamping hoop, and then the pliers are clamped, so that one free end is clamped at the other free end.
However, simple pre-expansion clamps can only be operated by pliers, of many types, and other pre-expansion clamps can only be operated by special tools.
In addition, in the above operation, when the clamping force applied to the pliers is unstable, the clamp is easy to fly out of the pliers, and the clamp may injure the worker and the nearby worker; the experience is insufficient, the self is easily injured, and the production efficiency is low, so that the method has higher requirements on operators.

Effects and effects of the embodiments
According to the clamp subassembly that this embodiment is related, a pair of looks adaptation ground butt head has, this butt head has the installation face, an inclined plane, concave surface and first plane, first plane is connected with the one end of concave surface, the inclined plane is connected with the other end of concave surface, the concave surface is the cambered surface, this concave surface forms with first plane and draw-in groove with big foot and little foot looks adaptation, consequently, when installing the binding clip that this embodiment provided and open pre-open type clamp, big foot on the pre-open type clamp slides in the draw-in groove along the inclined plane on one of them butt head, big foot on the pre-open type clamp slides in the draw-in groove along the inclined plane on another butt head, because pre-open type clamp and binding clip area of contact are big among the prior art pliers and pre-open type clamp area of contact for the stable butt of pre-open type clamp and binding clip. Therefore, the use of the binding clip provided in this embodiment enables the pre-expansion type band to be opened safely.
Further, because the clamp head is provided with the inclined surface, the large foot and the small foot of the pre-expansion type clamp can slide into the clamping groove through the inclined surface, so that a pipe fitting connecting person can clamp the pre-expansion type clamp.
Furthermore, the third plane is higher than the second plane, so when the pre-expansion type clamp is converted from a release state to a pre-expansion state, the pair of third planes are abutted, the purpose of limiting is achieved, and the operation safety is further improved.
Furthermore, the concave surface is tangent to the inclined surface and the first plane, so that the clamp head can be conveniently separated from the pre-opened clamp in a pre-opened state.
Furthermore, because the big foot of pre-expansion type clamp is provided with the nose eye, consequently, the bridge of the nose card can carry out stable support to the big foot in the nose eye.
Further, since the nose bridge is obliquely arranged on the outer side of the small foot arc, a pipe connector can gradually apply pressure to change the pre-expansion type clamp from the release state to the pre-expansion state, so that the operation safety is improved.
Furthermore, because the big foot and the little foot of pre-open type clamp all are equipped with the perk for pre-open type clamp card is in the draw-in groove better.
Further, because the clamp release clamp has locking mechanism, consequently, the accessible is with the locating plate card on the locating pin for first articulated pole keeps in fixed position with the second articulated pole, need not the long-time tight pincers main part of user and makes non-pre-open type clamp keep opening the state. In addition, close clamp release pincers on the locating pin through with the locating plate card under unused state, conveniently manage clamp release pincers.
The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention.
In the above embodiments, the clip release clip has a locking mechanism, however, this locking mechanism does not affect the clip release clip to open the pre-expanded clip, and therefore, in other embodiments, the locking mechanism may be omitted.
