Abstract

The utility model discloses a sucker rod assembly mechanism with a reset function. The mechanism comprises two sucker rods and a connecting tube (4), wherein the connecting tube (4) is provided with an inner thread. Each sucker rod comprises a cylindrical sucker rod body (1), a thread head (2) and a connecting rod (5) connecting the sucker rod body (1) with the thread head (2). Each thread head (2) is provided with an outer thread matched with the inner thread of the connecting tube (4). The two sucker rods are embedded into the connecting tube (4) from the two ends of the connecting tube (4) through the thread heads (2) respectively and are connected with the connecting tube (4). The connecting rods (5) of the two sucker rods are located in the connecting tube (4). An elastic reset element (6) is connected between the side wall of each connecting rod (5) and the inner wall of each connecting tube (4). Due to the facts that the two sucker rods are connected through the connecting tube (4) and the elastic reset elements (6) are additionally arranged, by means of the function of a connecting mode of thread matching, the risks of cracking of the assembly mechanism are reduced, and normal oil exploitation can be guaranteed.

Description

Sucker rod assembling mechanism with reset function
Technical field
The utility model relates to the frame for movement of field of petroleum exploitation, specifically is the sucker rod assembling mechanism with reset function.
Background technology
Usually be applied to rod pumping system in the oil exploitation, wherein, rod pumping system mainly is made up of oil pumper, sucker rod, oil well pump three parts, oil pumper is oil production equipment, sucker rod then is the critical component of oil pumping system, sucker rod is used for connecting oil well pump and oil pumper, and plays the effect of transferring power.The length of single sucker rod is generally 7.6 meters or 8 meters; when adopting sucker rod to connect oil pumper and oil well pump; generally need many sucker rods are spliced; Pin Jie sucker rod is when using now; fracture usually can appear because twisting resistance is excessive in the syndeton between two sucker rods, and this can have influence on the normal exploitation of oil.
The utility model content
The purpose of this utility model is that the sucker rod that solves existing splicing is prone to the problem that syndeton ruptures when using, a kind of sucker rod assembling mechanism with reset function is provided, it is by the opposing twisting resistance, and then reduce the risk that fracture appears in sucker rod connection structure, guarantee normally carrying out of oil exploitation.
The purpose of this utility model is achieved through the following technical solutions: the sucker rod assembling mechanism with reset function, the tube connector that comprises two sucker rods and circular casing shape, described tube connector is provided with internal thread, described sucker rod comprises columned sucker rod body, the connecting rod of thread head and connection sucker rod body and thread head, described thread head is provided with the external screw thread with tube connector internal thread coupling, two sucker rods embed in the tube connector from the tube connector two ends by thread head respectively and are connected with tube connector, the connecting rod of two sucker rods all is positioned at tube connector, and is connected with elastic reset spare between connecting rod sidewall and the tube connector inwall.The utility model connects sucker rod by tube connector, and tube connector is when connecting two sucker rods, and the two ends of tube connector have all embedded sucker rod.
Be arranged with on the described sucker rod body and be positioned at the outer spacing ring of tube connector.Wherein, the utility model limits sucker rod by spacing ring and embeds the degree of depth in the tube connector.
Embed in the tube connector when being subjected to bigger active force for fear of spacing ring, the outer ring diameter of described spacing ring is greater than the internal diameter of tube connector.
Sucker rod body of the present utility model, thread head and spacing ring both can become one, can connect as one by the mode of welding again, in order to strengthen the structural strength of sucker rod, improve the ability of its opposing stress, as preferably, described sucker rod body, thread head and spacing ring become one.
Because of spring be convenient to draw materials, with low cost, as preferably, described elastic reset spare is spring.
Compared with prior art, the utlity model has following beneficial effect: (1) the utility model comprises the tube connector of two sucker rods and circular casing shape, wherein, sucker rod comprises columned sucker rod body and the thread head that is connected with the sucker rod body, two sucker rods all are connected with tube connector by the mode of screw thread coupling, this can cushion the twisting resistance between the syndeton, reduces the risk that occurs fracture when the utility model is used.
(2) connecting rod of two sucker rods of the utility model all is positioned at tube connector, be connected with elastic reset spare between connecting rod sidewall and the tube connector inwall, distortion can twist when elastic reset spare is subjected to twisting resistance when sucker rod rotates, also can cushion twisting resistance, elastic reset spare can not drive sucker rod and resets when sucker rod is subjected to reversing, so, can further reduce the risk that fracture appears in package assembly of the present utility model, structure was firm when assurance connected two sucker rods, and then can avoid sucker rod connection structure fracture to occur and influence the normal exploitation of oil.
(3) be arranged with the spacing ring that is positioned at outside the tube connector on the sucker rod body of the present utility model, wherein, spacing ring can play spacing and effect that bear twisting resistance, and then can strengthen the ability of resisting stress when the utility model is used.

Fig. 1 is the structural representation of the utility model embodiment.
The corresponding name of Reference numeral is called in the accompanying drawing: 1, sucker rod body, 2, thread head, 3, spacing ring, 4, tube connector, 5, connecting rod, 6, elastic reset spare.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment:
As shown in Figure 1, sucker rod assembling mechanism with reset function, comprise two sucker rods and circular casing shape tube connector 4, wherein, tube connector 4 is provided with internal thread, sucker rod comprises sucker rod body 1, the connecting rod 5 of thread head 2 and connection sucker rod body 1 and thread head 2, sucker rod body 1 constitutes cylindric, thread head 2 is provided with the external screw thread with tube connector 4 internal threads coupling, two sucker rods embed in the tube connector 4 from tube connector 4 two ends by thread head 2 respectively and are connected with tube connector 4, and namely the two ends of tube connector 4 are connected with a sucker rod by the mode of screw thread coupling respectively.
The connecting rod 5 of two sucker rods all is positioned at tube connector 4, is provided with elastic reset spare 6 between connecting rod 5 sidewalls and tube connector 4 inwalls.For the ease of drawing materials and saving cost, elastic reset spare 6 is preferably spring, and the quantity of spring is many, and the two ends of every spring are connected to connecting rod 5 sidewalls and tube connector 4 inwalls.Be arranged with on the sucker rod body 1 and be positioned at the outer spacing ring 3 of tube connector 4, in order to guarantee that spacing ring 3 can embed the degree of depth in the tube connector 4 to sucker rod and carry out spacingly, the outer ring diameter of spacing ring 3 is greater than the internal diameter of tube connector 4.In order to strengthen the intensity of sucker rod, as preferably, sucker rod body 1, thread head 2 and spacing ring 3 threes become one.
