Description
Technical field
The utility model belongs to assembly tooling technical field, is specifically related to a kind of spanner for trim ring assembling.
Background technology
Trim ring assembling need to utilize wrench operated to carry out conventionally. For the ease of assembling, conventional trim ring has trim ring groove or hole conventionally, to coordinate with spanner, spanner is realized fastening function by trim ring groove or hole rotation trim ring.
But; also there is at present some trim rings that have appearance requirement or the special trim ring of structure; it is not because the consideration of outward appearance or structural factor arranges trim ring groove or hole; this trim ring is in the time of assembling; because it cannot coordinate with spanner; causing spanner can not use or assemble effect poor, how in can realizing assembling trim ring, also will protect the presentation quality of part not damaged, is the subject matter facing in current trim ring assembling.
Utility model content
For above defect or the Improvement requirement of prior art; the utility model provides a kind of elastic wrench for trim ring assembling; it is by being optimized design to spanner structure; make to realize trim ring assembling by the frictional force of spanner and trim ring; thereby solve the trim ring assembly problem that there is no spanner groove or hole, in realizing functions of wrench, protect the presentation quality of part not damaged.
For achieving the above object, according to the utility model, provide a kind of elastic wrench for trim ring assembling, wherein, this elastic wrench comprises that the wrench body and the edge that are hollow cylinder shape are circumferentially enclosed within the rubber sleeve on cylindrical shell, wherein, the cylindrical shell barrel periphery of described wrench body is provided with many elastic grooves vertically, and described rubber sleeve is sleeved on cylindrical shell working position periphery, can make spanner profile shrink, increase elasticity, be convenient to spanner simultaneously and coordinate with trim ring, thereby the elasticity of being beneficial to and frictional force realize trim ring assembling.
As improvement of the present utility model, the barrel periphery of described wrench body working position is provided with projection, for the location of assembling.
As improvement of the present utility model, the elastic groove of described cylindrical shell periphery setting is many.
As improvement of the present utility model, the elastic groove of described cylindrical shell periphery setting is three, is uniformly distributed circumferentially in barrel periphery.
As improvement of the present utility model, described wrench body is metal material, is preferably aluminium or copper material.
In general, the above technical scheme of conceiving by the utility model compared with prior art, has following beneficial effect:
(1) the utility model is provided with many elastic grooves in the cylindrical shell periphery of wrench body, for trim ring Elastic Contact with produce frictional force
(2) the utility model work end is provided with rubber sleeve along being circumferentially enclosed within cylindrical shell, and it can make spanner profile shrink, and increases elasticity, is convenient to spanner simultaneously and coordinates with trim ring, makes assembling more convenient, and protection trim ring presentation quality.
(3) spanner of the present utility model, by specific shape, utilizes the elasticity of material, realizes trim ring assembling by the frictional force of spanner and trim ring, solves the trim ring assembly problem that there is no spanner groove or hole, raises the efficiency, and ensures the quality of products.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model. In addition,, in each embodiment of described the utility model, involved technical characterictic just can combine mutually as long as do not form each other conflict.
According to the constructed a kind of elastic wrench for trim ring assembling of the utility model embodiment, comprise that wrench body 1 and the elastic ring 3 being sleeved in wrench body 1 form.
Fig. 1 is the structural representation of the spanner of the present embodiment, and as shown in Figure 1, the main body 1 of the elastic wrench of the present embodiment adopts sleeve-shaped, and bush material is preferably aluminium from economic and practical consideration, can be also copper material and other metalworks.
As shown in Figure 1, sleeve periphery is provided with many equally distributed elastic grooves 2 vertically, spatially each groove be parallel to each other (be preferably in one embodiment 3, it is upwards mutually 120 degree in week). Preferably in the bottom of every elastic groove, groove is widened, to increase elasticity. Bottom width can be groove width 3-5 doubly, in the present embodiment preferably 3 times, but be not limited to this in the utility model, specifically can arrange according to actual conditions.
As shown in Figure 1, the working position of spanner is provided with projection, coordinates the parts of location as spanner with trim ring 4 end faces, accurate positioning when assembling.
The flexible circle 3 of working position periphery overcoat of spanner; for example rubber sleeve; it is set in the working position of spanner cylindrical shell end; rubber sleeve can make spanner cylindrical shell profile shrink; increase elasticity, be convenient to spanner simultaneously and coordinate with trim ring 4, make assembling more convenient; and protection trim ring 4 presentation qualities, spanner utilizes elasticity and frictional force to realize trim ring assembling.
As shown in Figure 2, be the schematic diagram of two kinds of different structure trim rings, the trim ring with screw-driver slot can rotate with traditional spanner sheet, and the trim ring with screw-driver slot just can not rotate with elastic wrench.
When work, utilize elasticity that spanner working position is shunk, pack in trim ring 4 endoporus, the step of spanner working position coordinates location with trim ring 4 end faces, not crooked while ensureing spanner work; Utilize spanner elastic groove to produce radical elasticity simultaneously, when spanner rotation, have enough large frictional force to drive trim ring 4 to rotate together, realize assembling function.
As shown in Figure 3, in the time of assembling, the working position of wrench body 1 coordinates with the endoporus of trim ring 4, utilizes the relative position of flexible fastening spanner and trim ring 4; The enough large frictional force of utilizing rotary course to produce, assembling trim ring 4 put in place and ensure fastening reliably.
In the present embodiment, by three elastic grooves, utilize flexible fastening spanner and the trim ring 4 of material, realize assembling function.
The spanner of this programme, by specific shape, utilizes the elasticity of material, realizes trim ring assembling by the frictional force of spanner and trim ring 4, solves the trim ring assembly problem that there is no spanner groove or hole, raises the efficiency, and ensures the quality of products.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
