Description
Technical field
The utility model is related to a kind of tensioning apparatus, more particularly to inner wall tensioning apparatus.
Background technology
Tensioning apparatus used at present is mainly that plastic shrapnel is constituted, and is connect with product orientation column, utilizes plastics bullet
The tension of piece comes pair, and hollow product carries out expansion setting, although plastic shrapnel structure is relatively simple, the peace with product orientation column
Fill it is more convenient, expansion it is more uniform, be less prone to expansion out-of-flatness the case where, plastic shrapnel band had the disadvantage that at that time,
Elasticity is difficult to adjust, and the size of expansion is fixed, can not use with other products not of uniform size, strainer is due to by plastics structure
At, the phenomenon that being susceptible to fracture when in use, and plastic shrapnel is easy the inner wall of scratching products, it is therefore desirable to a kind of scheme
To solve the above problems.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of inner wall tensioning apparatus.
The utility model is to solve above-mentioned technical problem by following technical proposals：A kind of inner wall tensioning apparatus,
Including pedestal, product center positioning column, product, left side fixed block, right side fixed block, extension rod, spring cushion block, spring groove, bullet
Spring and spherical tensioning contact, the product center positioning column are mounted on pedestal, and the product is mounted on product center positioning column
Outside, the left side fixed block and right side fixed block are separately mounted in the groove at left and right sides of product, the extension rod connection
The inner wall and spring cushion block of product, the spring groove are connect with spring cushion block, and the spring is mounted in spring groove, the spherical shape
Tensioning contact is connect with spring, and is connect with the inner wall on the right side of product.
Preferably, the spring is carbon steel pressure spring.
Preferably, ranging from 5 millimeters to 10 millimeters of the tensioning of the spring.
Preferably, the left side fixed block and the opposite both sides for being mounted on product of right side fixed block.
The positive effect of the utility model is：The utility model inner wall tensioning apparatus is compared to current plastics bullet
Piece tensioning apparatus, mechanism is more compact, is suitble to use in the range of narrow space, whole since it uses spring structure
The intensity higher of structure, is hardly damaged, and the size of tension can be adjusted in a certain range, when product is inserted into,
It is tensioned using spherical surface, good guiding role can be played, product inner wall is avoided to occur scratching phenomenon.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, pedestal 1, product center positioning column 2, product 3, left side fixed block 4, right side fixed block 5, extension rod 6, spring
Cushion block 7, spring groove 8, spring 9, spherical tensioning contact 10.
Specific implementation mode
The utility model preferred embodiment is provided below in conjunction with the accompanying drawings, the technical solution of the utility model is described in detail.
As shown in Figure 1, a kind of inner wall tensioning apparatus comprising pedestal 1, product center positioning column 2, product 3, left side are fixed
Block 4, right side fixed block 5, extension rod 6, spring cushion block 7, spring groove 8, spring 9 and spherical tensioning contact 10, product center positioning
Column 2 is mounted on pedestal 1, and product 3 is mounted on 2 outside of product center positioning column, and left side fixed block 4 and right side fixed block 5 are distinguished
In the groove of 3 left and right sides of product, extension rod 6 connects the inner wall and spring cushion block 7 of product 3, spring groove 8 and spring pad
Block 7 connects, and spring 9 is mounted in spring groove 8, and spherical shape tensioning contact 10 is connect with spring 9, and connects with the inner wall on 3 right side of product
It connects.
Spring 9 is carbon steel pressure spring.
Ranging from 5 millimeters to 10 millimeters of the tensioning of spring 9.
Left side fixed block 4 and the opposite both sides for being mounted on product 3 of right side fixed block 5.
For the utility model inner wall tensioning apparatus compared to current plastic shrapnel tensioning apparatus, mechanism is more compact, fits
Conjunction uses in the range of narrow space, since it uses spring structure, integrally-built intensity higher to be hardly damaged, and
The size of tension can be adjusted in a certain range, when product is inserted into, is tensioned using spherical surface, can be played and lead well
To effect, product inner wall is avoided to occur scratching phenomenon.
Particular embodiments described above, the technical issues of to the solution of the utility model, technical solution and advantageous effect
It has been further described, it should be understood that the foregoing is merely specific embodiment of the utility model, not
For limiting the utility model, within the spirit and principle of the utility model, any modification for being made, changes equivalent replacement
Into etc., it should be included within the scope of protection of this utility model.
